Predictive modeling for postoperative delirium in elderly patients with abdominal malignancies using synthetic minority oversampling technique

BACKGROUND Postoperative delirium,particularly prevalent in elderly patients after abdominal cancer surgery,presents significant challenges in clinical management.AIM To develop a synthetic minority oversampling technique(SMOTE)-based model for predicting postoperative delirium in elderly abdominal cancer patients.METHODS In this retrospective cohort study,we analyzed data from 611 elderly patients who underwent abdominal malignant tumor surgery at our hospital between September 2020 and October 2022.The incidence of postoperative delirium was recorded for 7 d post-surgery.Patients were divided into delirium and non-delirium groups based on the occurrence of postoperative delirium or not.A multivariate logistic regression model was used to identify risk factors and develop a predictive model for postoperative delirium.The SMOTE technique was applied to enhance the model by oversampling the delirium cases.The model’s predictive accuracy was then validated.RESULTS In our study involving 611 elderly patients with abdominal malignant tumors,multivariate logistic regression analysis identified significant risk factors for postoperative delirium.These included the Charlson comorbidity index,American Society of Anesthesiologists classification,history of cerebrovascular disease,surgical duration,perioperative blood transfusion,and postoperative pain score.The incidence rate of postoperative delirium in our study was 22.91%.The original predictive model(P1)exhibited an area under the receiver operating characteristic curve of 0.862.In comparison,the SMOTE-based logistic early warning model(P2),which utilized the SMOTE oversampling algorithm,showed a slightly lower but comparable area under the curve of 0.856,suggesting no significant difference in performance between the two predictive approaches.CONCLUSION This study confirms that the SMOTE-enhanced predictive model for postoperative delirium in elderly abdominal tumor patients shows performance equivalent to that of traditional methods,effectively addressing data imbalance.

Nab-paclitaxel(abraxane)-based chemotherapy to treat elderly patients with advanced non-small-cell lung cancer:a single center,randomized and open-label clinical trial

Background： The purpose of this study is to evaluate the clinical efficacy and safety of abraxane-based chemotherapy with/without nedaplatin in elderly patients with non-small-cell lung cancer （NSCLC）. Materials and methods： From October 2009 to January 2013, 48 elderly patients （≥65 years） with NSCLC were investigated in this clinical trial. The patients were randomized and equally allocated into arms A and AP- （A） abraxane （130 mg/m2, days 1, 8）; （B） abraxane ＋ nedaplatin （20 mg/m2 days 1-3, q3w）. The parameters of objective response rate （ORR）, disease control rate （DCR）, progression-free survival （PFS）, overall survival （OS） and side effects were evaluated between two arms. Results： Over 80% of the patients completed four cycles of chemotherapy. The total ORR was 21.3 %, DCR was 55.3%, PFS 4.5 months and OS 12.6 months. No significant difference was found between arms A and AP in terms of ORR （16.7% vs. 26.1%, P=0.665） or DCR （55.3% vs. 56.5%, P=0.871）. The median PFS in arm A was 3.3 months [25-75% confidence interval （CI）： 3.1-7.2] and 5.5 months （25-75% CI： 3.2-7.0） in arm AP with no statistical significance （P=0.640）. The median OS in arm A was 12.6 months （25-75% CI： 5.7-26.2） and 15.1 months （25-75% CI： 6.4-35.3） in arm AP with no statistical significance （P=0.770）. The side effects were mainly grade 1-2. The incidence of grade 3-4 toxicities was 29.1% in arm A and 62.5% in arm AP with a statistical significance （P=0.020）. Conclusions： Compared with combined therapy, abraxane alone chemotherapy was beneficial for elderly NSCLC patients with better tolerability and less adverse events, whereas did not significantly differ in terms of ORR, DCR, PFS or OS.

The Process of How Elderly Patients with Lung Cancer Who Are Receiving Molecularly Targeted Therapy with Oral Agents Establish Self-Management

Purpose: In Japan, many elderly cancer patients are receiving chemotherapy using oral molecularly targeted drugs. They receive treatment in outpatient setting and have a need to self-manage at home. The purpose of this study was to clarify how elderly patients with lung cancer who are undergoing treatment with molecularly targeted drugs in outpatient setting establish self-management. Methods: The study used Kinoshita’s Modified Grounded Theory. Semi-structured interviews were conducted with 17 patients (eight males and nine females). Results: This study identified six categories: Accepting life with cancer, Maintaining activities of daily living without feeling shackled by cancer, Reconsidering how to continue being themselves in daily life until life comes to an end, Using trial and error to integrate treatment and daily living, Formulating their criteria for continuing treatment, and Obtaining help from caregivers. Conclusion: The self-management process in elderly patients consisted of maintaining treatment and integrating treatment with daily living. And they are exploring the effects of treatment and side effects in order to live their own life. Implications for Nursing: In many elderly patients with lung cancer the purpose of treatment is curative extension of survival and improved quality of life. Our findings suggest that is important we help patients to identify how patients want to live, identify ways to improve their quality of life, and share the goals of treatment between the patient and the caregiver.

The Results Observation on Adjuvant Chemotherapy with Microwave Hyperthermia and Stereotactic Radiotherapy in Retreated Elderly Patients with Advanced (III/IV Stage) Lung Cancer

Objective: To evaluate the significance of adjuvant chemotherapy and radiotherapy (Gamma-knife) in the elderly patients with retreated advance lung cancer. Methods 83 patients (age 50 to 81 years) with retreating advanced (III/IV stage) lung cancer were divided into three groups according to patients received treating by different methods. The cases were treated by synchronous chemo-radiotherapy (A group), sequentially chemo-radiotherapy (B group) and continuous systematized chemotherapy alone (C group). The systemic 3-dimensional orientation apparatus was used in radiotherapy. The chemotherapy regimen in combined radiotherapy was given by common first line regimen on lung cancer. The regimen of chemotherapy combated with whole body hyperthermia by using micro-wave on abodeman about 2 or 3 line was used in C group only. Results: The overall responses rates (RR) of A, B and C groups were 17.1%, 11.5% and 31.8%, but it was non-significance difference (P > 0.05). Overall responses rates (RR) of III and IV stage groups were 18.2% and 20.0%. The average overall survival time (OS) and median survival time (MST) of the patients treated by chemotherapy (C group) were highest about 14.2 and 9.3 months (respectively at A group 6.7 and 6.0 months. P < 0.01), in which B group was longer than A group (P < 0.05), and 95.5% CI value was not overlap. The total survival time of postoperative patients was longer in the various groups by different treated than that in non-operations. Conclusion: The rates (RR) of III and IV stage groups were non-significance difference. The higher of ORR, OS and MST in a few patients of re-treated advanced lung cancer was presented in case with treated by continuous system chemotherapy. There were survival superiority in initial postoperative patients groups by different treated. It is a profitable and effect treatment that the pure reasonable systemic chemotherapy was used for elderly case with advanced retreated lung cancer.

The related effects of astragalus polysaccharides on the improvement of bone marrow suppression and hematopoietic stem cells during chemotherapy in elderly patients with lung cancer

Objective:To investigate the effects of astragalus polysaccharides(APS)on bone marrow suppression and hematopoietic stem cells during chemotherapy in elderly patients with lung cancer.Methods:120 elderly patients with lung cancer treated in the first hospital of Xingtai city from January 2019 to early December 2019 were divided into the treatment group and the control group by the random number table method,all of whom received pemetrexed+carboplatin chemotherapy,and the treatment group was treated with APS at the same time.The efficacy was evaluated after 2 cycles of chemotherapy,bone marrow suppression was observed,and levels of TCM symptoms score,peripheral blood T lymphocyte subgroup index,L-selectin(CD62L)and macrophage differentiation antigen-1(Mac-1)were measured before and after 2 cycles of chemotherapy.Results:The response rate(RR)was 56.67%in the treatment group and 45.00%in the control group,with no statistically significant difference(P>0.05);The disease control rate(DCR)in the treatment group was 81.67%,which was significantly higher than 65.00%in the control group(P<0.05);The reduction degree of leukopenia in the treatment group was significantly lower than that in the control group(P<0.05);The treatment group had a platelet reduction of grade 1+2 at a rate of 40.00%,and hemoglobin reduction of grade 1+2 at a rate of 28.33%,which were significantly lower than the control group at 65.00%and 58.33%(P<0.05);Compared with those before chemotherapy,the total score of TCM symptoms,serum CD62L and Mac-1 levels in the two groups all decreased significantly after chemotherapy,and they were significantly lower in the treatment group than in the control group(P<0.05);After chemotherapy,CD3+,CD4+and CD4+/CD8+in the treatment group increased significantly and they were all higher in the treatment group than in the control group,while CD8+decreased significantly and was lower in the treatment group than in the control group(P<0.05).There was no statistically significant difference in T lymphocyte subsets before and after chemotherapy in the control group(P>0.05).Conclusion:Astragalus polysaccharide can improve the chemotherapy effect and improve the bone marrow suppression in elderly patients with lung cancer,which may be related to its obvious enhancement of immune function and decrease of CD62L and Mac-1 levels.

Chemotherapy (Gemcitabine plus Carboplatin versus Paclitaxel plus Carboplatin) in Elderly Patients with Non-Small Cell Lung Cancer

Background: This retrospective study was to evaluate the efficacy and toxicity of gemcitabine plus carboplatin (GC regimen) and paclitaxel plus carboplatin (PC regimen) combination chemotherapy in elderly patients with non-small cell lung cancer. Methods: Seventy-four patients (GC regimen, n = 44;PC regimen, n= 30) received gemcitabine at a dose of 1000 mg/m2 on days 1 and 8, and carboplatin with the target dose of area under the curve (AUC) of 4 on day 8 every 28 days and paclitaxel at a dose of 70 mg/m2 on days 1, 8 and 15, and carboplatin with the target dose of AUC of 5 on day 1 every 28 days. Patients were divided in two groups (younger one: n = 42, old;elderly one: n= 32, ≥70 years old). Results: A total of 222 cycles of the treatment wasadministered. Seventy-one patients (95.9%) completed the scheduled cycles. Two patients in the elderly group were discontinued (6.3%) due to hematological toxicity and melena in the GC regimen and to grade 4 pneumonia in the PC regimen. The dose was reduced in 8 patients (10.8%) due to grade 4 thrombocytopenia. Grade 3/4 neutropenia was not significantly observed in both groups (younger group: 24/42, 57.1%;elderly group: 19/32, 59.4%, p = 0.8471). The nonhematological toxicities were mild in both groups. However, in theelderly group, grade 3/4 thrombocytopenia was significantly observed in the GC group (GC: 5/17, 29.4%;PC: 0/15, 0.0%, p = 0.0222). There was no treatment-related death. Conclusion: These results demonstrate that the GC and PC combination chemotherapies are efficacious and feasible regimens for lung cancer therapy, especially, both regimens should be considered as one of the standard therapies for elderly patients during lung cancer therapy.

Elderly Lung Cancer Patients and Radiochemotherapy: A Review

More than 60% of lung cancer patients in Europe and the USA are older than 65 years at the time of diagnosis. Despite this, elderly patients are generally under-represented in clinical trials. That being so, a general consensus on how to treat elderly patients is still far from being achieved. In this review, we address some of the issues and challenges surrounding the treatment of older cancer patients and radiochemotherapy. We discuss the existing evidence related to radio-chemotherapy in the elderly, focusing primarily on the lung cancer (NSCLC and SCLC) most commonly seen in older patients, and making general treatment recommendations.

Combining the Patient-Generated Subjective Global Assessment (PGSGA) and Objective Nutrition Assessment Parameters Better Predicts Malnutrition in Elderly Patients with Colorectal Cancer

Background Malnutrition is common in colorectal cancer(CRC)patients,especially in elderly patients.The Patient-Generated Subjective Global Assessment(PG-SGA)is a widely used tool developed to detect malnutrition.The aim of this study was to compare the value of the PG-SGA and objective nutrition assessment parameters,in order to identify a better predictive index for malnutrition in elderly patients with CRC.Methods A total of 131 elderly patients(age≥60 years)with CRC were included and were evaluated for their individual nutritional status using the PG-SGA.Anthropometric and serological indicators were also assayed within 48 h of admission to the hospital.Body composition analysis was implemented by bioelectrical impedance analysis(BIA)instrument.The Chi-squared test,univariate and multivariate logistic regression analysis,or Spearman’s rank correlation analysis were used to determine the differences among the above indices and parameters with regard to predicting malnutrition.Results According to the PG-SGA score,the incidence of total malnutrition in elderly patients with CRC was 80.92%(PG-SGA score≥2),which increased with age.It was found that 28%of the patients with PG-SGA classification A(PG-SGA score 0-1)had a low fat-free mass index(FFMI).Compared with those with PG-SGA A,patients with PG-SGA C PG-SGA score≥9)showed an increased neutrophil to lymphocyte ratio(NLR)and an increased platelet and lymphocyte ratio(PLR)(median=1.78 VS.2.35,P=0.015 and median=108.8 VS.141.6,P=0.001,respectively).In terms of objective nutrition assessment parameters,severely malnourished CRC patients had significantly lower values of serum albumin(ALB),and retinol conjugated protein(RBP)than those who were well-nourished[(38.35±4.84)g/L VS.(40.56±3.44)g/L,P=0.039 and(30.31±15.83)mg/L VS.(39.01±11.95)mg/L,P=0.033,respectively].The Spearman’s rank correlation analysis showed that the PG-SGA findings had positive correlations with the NLR and PLR;while it had negative correlations with the FFMI,body mass index(BMI),ALB,prealbumin,and RBP.Conclusions In clinical practice,a comprehensive nutritional diagnosis,including the PG-SGA score and these objective indicators,can avoid the underdiagnosis of malnutrition,and is more suitable to detect malnutrition(as well as its causes)in elderly patients with CRC.

Clinical outcomes of targeted therapies in elderly patients aged ≥ 80 years with metastatic colorectal cancer

BACKGROUND The 5-fluorouracil-based chemotherapy combined with oxaliplatin or irinotecan is usually used in colorectal cancer(CRC).The addition of a targeted agent(TA) to this combination chemotherapy is currently the standard treatment for metastatic CRC.However,the efficacy and safety of combination chemotherapy for metastatic CRC in patients aged above 80 years has yet to be established.AIM To assess the clinical outcomes and feasibility of combination chemotherapy using a TA in extremely elderly patients with CRC.METHODS Eligibility criteria were:(1) Age above 80 years;(2) Metastatic colorectal cancer;(3) Palliative chemotherapy na?ve;(4) Eastern Cooperative Oncology Group performance status 0-1;and(5) Adequate organ function.Patients received at least one dose of combination chemotherapy with or without TA.Response was evaluated every 8 wk.RESULTS Of 30 patients,the median age of 15 patients treated with TA was 83.0 years and that of those without TA was 81.3 years.The median progression-free survival(PFS) and overall survival(OS) in patients treated with TA were 7.4 mo and 15.4 mo,respectively,compared with 4.4 mo and 15.6 mo,respectively,in patients treated without TA.There was no significant difference in PFS(P:0.193) and OS(P:0.748) between patients treated with and without TA.Common grade 3/4 hematologic toxicities were anemia(16.7%) and neutropenia(10.0%).After disease progression,the median OS of patients who were treated with and without salvage chemotherapy were 23.5 mo and 7.0 mo,respectively,suggesting significant difference in OS(P = 0.001).CONCLUSION Combination chemotherapy with TA for metastatic CRC may be considered feasible in patients aged above 80 years,when with careful caution.Salvage chemotherapy can help improve OS in some selected of these elderly patients.

Comparison of involved-field intensity-modulated radiotherapy combined with S-1 vs radiotherapy alone for elderly patients with esophageal cancer

BACKGROUND It is estimated that about 30%of esophageal cancer(EC)patients are over 70 years old.Therefore,there is less evidence on the diagnosis and management of elderly EC patients.It is important to explore how elderly EC patients benefit from radical radiochemotherapy regimens,including the target area of radiotherapy(RT),radiation dose and fraction,and choice of chemotherapy drugs.AIM To compare the efficacy of involved-field intensity-modulated RT(IF-IMRT)combined with S-1 vs RT alone in the treatment of elderly EC patients in terms of safety,short-term response,and survival.METHODS Thirty-four EC patients aged>70 years were prospectively enrolled between December 2017 and December 2019.Based on the random number table,they were divided into an IF-IMRT+S-1 group and an IF-IMRT alone group,with 17 patients in each group.All patients were treated with IF-IMRT at a dose of 50.4-56 Gy in 28-30 fractions(1.8-2 Gy/fraction,5 fractions/wk).Oral S-1 was administered concomitantly in the IF-IMRT+S-1 group for 14 consecutive days,and a second cycle was started 7 d after drug withdrawal.After RT,4 cycles of S-1 treatment were offered as the consolidation chemotherapy.The safety,short-term response,and survival were observed after the treatment.RESULTS As of April 2022,these 34 patients had been followed up for 15.2-32.5 mo,with a median follow-up period of 24.5 mo.Complete efficacy indicators were obtained from all the patients.The objective response rate was 88.2%vs 76.5%,respectively,in the IF-IMRT+S-1 group and the RT alone group,where as the disease control rate was 100%vs 82.4%,respectively.The incidence of adverse events including grade 1-2 fatigue,granulocytopenia,thrombocytopenia,anemia,radiation esophagitis,radiation-induced skin injury,and radiation-induced lung injury was not significantly different between these two groups,so was the incidence of the grade 3 radiation esophagitis(0%vs 5.7%).The rate of progressive disease(PD)was 52.9%(n=9)in the IF-IMRT+S-1 group and 64.7%(n=11)in the RT alone group.The median progression-free survival(PFS)was 23.4 mo vs 16.3 mo,and the 2-year PFS rate was 42%vs 41.2%.The median overall survival(OS)was 27.0 mo vs 23.0 mo,and the 2-year OS rate was 58.8%vs 47.1%.Multivariate analysis showed that age was a significant prognostic factor(P=0.0019);patients aged<75 years had a significant survival advantage over patients aged≥75 years.The locations of EC also affected the prognosis.In the IFIMRT+S-1 group,the number of chemotherapy cycles was a significant prognostic factor(P=0.0125),and the risk of PD was significantly lower in EC patients who had received 6 cycles of chemotherapy than those who had received 2-5 cycles of chemotherapy.CONCLUSION Compared with IF-IMRT alone,IF-IMRT+S-1 shows the benefits of preventing PD and prolonging survival without increasing adverse reactions.Therefore,this concurrent radiochemotherapy deserves clinical application.

Implantable Venous Access Ports for Chemotherapy in Lung Cancer Patients: Comparison of the Femoral and Subclavian Vein Approaches without Guidance

Background: The goal of this study was to retrospectively compare the initial success rate and rate of intraoperative and late complications between the femoral and subclavian vein approaches used to implant venous access ports without guidance in lung cancer patients. Methods: We conducted a retrospective review of total 163 lung cancer patients who underwent implantations of a central venous access port for chemotherapy. 95 patients received the ports by the femoral vein blind-puncture technique and 68patients had the port implanted via the subclavian vein blind-puncture technique. The initial success rate of port implantation and the frequency of occurrence of complications were calculated. Results: The primary success rate of venous port implantation was 93.7% for femoral approach and 88.2% for the subclavian approach respectively (p < 0.05). Intraoperative complications developed in two patients (2.1%) in the femoral approach group and in five patients (7.4%) in the subclavian approach group. Although a higher intraoperative complication ratio for the subclavian approach was encountered compared to that for the femoral vein approach, there was no statistically significant difference (p = 0.103). Nor was there any statistically significant difference in terms of the occurrence of late complications. Conclusions: Venous access port implantation via the femoral vein approach is safe, and its success rate is very high, with the equal complication rates comparable to the subclavian approach. This approach avoids many of the intraoperative complications. Thus, the femoral vein approach for implanting a venous access port in lung cancer patients should be considered a valid, and safe technique.

Process of Decision-Making of Anti-Cancer Treatment in Elderly Patients with Advanced Lung Cancer

The aim of this study was to identify the decision-making process of anti-cancer treatment in elderly patients with advanced lung cancer. Semi-structured interviews were conducted with 17 patients aged 70 and above to collect data on their feelings and thoughts from the time of diagnosis till they made treatment decisions. The data was analyzed using the Modified Grounded Theory Approach that was modified by Prof. Yasuhito Kinoshita. We found the process to be composed of six categories. The results showed that elderly patients with advanced lung cancer were panicked over unavoidable death when informed of stage IV lung cancer and offered suggestions about anti-cancer treatment. However, trying to accept the situation where death is imminent, patients reconsidered having cancer in older age and recognized a desire to survive even in older age. This process diverged into two paths: one group of patients changed their ideas from radical to life-prolonging treatment by recognizing a desire to survive even in older age and then made anti-cancer treatment decisions by carefully choosing treatment that would allow to carry on their usual way of life;the other group of patients made treatment decisions by carefully choosing physicians to whom they could entrust their life in older age. These findings suggest that it is important for nurses to: 1) encourage patients to talk in order to have them think about what they have valued and want to value in the rest of their life;2) assess if patients prefer to decide on their own by carefully choosing treatment or entrust treatment decisions to physicians;and 3) offer support according to patients’ preferences.

The Clinical Investigation of Pemetrexed Plus Carboplatin as an Active and Tolerable Treatment Plan in Chinese Elderly Patients with Advanced Lung Adenocarcinoma

The standard chemotherapy for Chinese elderly patients with non-small cell lung cancer (NSCLC) remains undefined. The study was to evaluate the therapeutic effects as well as side effects of pemetrexed plus carboplatin regimen as the first-line therapy for Chinese elderly patients with advanced lung adenocarcinoma. Twenty-three Chinese elderly patients (male 14 and female 9, average age 73.7 years, range 70~81 years) with advanced lung adenocarcinoma received pemetrexed plus carboplatin as the first-line therapy, in detail, pemetrexed 500 mg/m2 and carboplatin AUC 5 mg/ml/m2 were given intravenously on day 1. The treatment was repeated everyday in the 21 days cycle. Therapeutic effects were evaluated at least after two cycles of treatment. The remission rate, disease control rate, time to progression and overall survival were observed. The results showed that all the cases were valid for response evaluation, with the complete remission 0 case, partial remission 8 cases, stabilize disease 9 cases and progression disease 6 cases. The remission rate (including complete remission and partial remission) was 34.8%, disease control rate 73.9%, the time to progression was 5.8 months and the overall survival 13.7 months. There showed the positive relationship between the curative effects (either time to progression or overall survival) and chemotherapy cycles. The main toxicities were bone marrow suppression, nausea and vomiting. There was no chemotherapy-related death. The data suggested that the combination regimen with pemetrexed plus carboplatin is an active and tolerable treatment plan for Chinese elderly patients with advanced lung adenocarcinoma, in which the side effects were tolerable and manageable.

A Multicenter Cohort Study for XELOX (Capecitabine, Leucovorin plus Oxaliplatin) Therapy as First-Line Treatment in Elderly Patients with Unresectable Colorectal Cancer

Oxaliplatin-based chemotherapy with bevacizumab is now widely used for colorectal cancer patients. This study evaluated the efficacy and tolerability of XELOX (capecitabine + oxaliplatin + leucovorin combined) therapy with or without bevacizumab in elderly patients. One hundred and seven patients, consisting of 52 elderly (>70 years of age) and 55 non-elderly, with unresectable colorectal cancer were enrolled in this multicenter cooperative group study using a database between October 2009 and March 2012. We evaluated the outcomes in terms of the median time to treat failure (TTF), overall response rate (ORR), disease control rate (DCR) and tolerability in both age groups. The median TTF for the XELOX + bevacizumab regimen was 7.1 months in the non-elderly group and 8.1 months in the elderly group (p = 0.838). There was no significant difference in TTF between the two groups. The ORR and DCR in the non-elderly group were 30.8% and 73.1%, respectively. In the elderly group, the ORR was 40.0% and the overall DCR was 90.0%. No severe or uncontrollable adverse events were observed in the two groups. These data indicated that the XELOX chemotherapy with or without bevacizumab has an equivalent efficacy in both groups, without increasing the adverse events even in the elderly population.

Decision-Making Process for the Place of Death of Elderly Patients with Advanced Cancer and Their Families

Purpose: This study aims to understand how elderly patients with advanced cancer and their families make a decision for a place of death for the patient. Methods: Semi-structured interviews were conducted with 17 pairs of elderly patients and members of their family. The patients had finished anticancer treatment and made some decision about the preferred place of death. A modified grounded-theory approach was used for the data analysis. Results: Making a “tentative” decision for the place of death of the elderly patients is a process with the core category [carefully choosing the final place for self-fulfillment]. The patients were “conducting a comprehensive review of the place of death” and “embracing the wishes for a way of life without difficulty”. Involving the family in making a “tentative” decision about the place of death of the elderly patients is the process with the core category [realizing the wish of patients in the terminal condition for the way for death]. The families were “examining the place of death from different aspects” and “respecting the patient’s intention as far as possible”. Conclusions: When the patients [carefully choosing the final place for self-fulfillment], it was important to reconcile their wishes with the burden on the families. When the families were trying to [realize the wish of patients in the terminal condition for the way for dying], it was important to balance the respect for the patient intentions and homecare they can provide for the patient. For the patients and their families, it is essential to mutually understand the intentions and wishes of the other party in decision making about the place of death.

Treatment Patterns and Mortality Risk among Elderly Patients with Metastatic Triple Negative Breast Cancer in the United States: An Observational Cohort Study Using SEER-Medicare Data

Purpose: Triple negative breast cancer is more aggressive than other breast cancer subtypes and accounts for up to 20% of all breast cancers. Despite the poorer prognosis, there are no approved targeted treatments available and chemotherapy remains the only choice. We examined treatment patterns and outcomes among elderly metastatic triple-negative breast cancer (mTNBC) patients in routine clinical practice. Methods: Patients were identified from the linked SEER-Medicare database between 1/1/2001 and 12/31/2013 and included de novo Stage IV (n = 776) and patients with distant metastasis followed an initial diagnosis of Stage I - III disease (n = 1851). Kaplan-Meier analyses and time-varying Cox proportional hazards regression were used to assess overall survival (OS). Results: The mean age at metastatic diagnosis was 77.6 years and 1259 (48%) patients received chemotherapy. Compared to <70 year olds, ≥70 year olds had worse performance status, higher comorbidity burden, and were less likely to receive chemotherapy (45% vs. 66%). Patients treated with chemotherapy had increased OS compared to untreated patients, and the survival advantage was more pronounced in the -month longer unadjusted OS compared to the ≥70 cohort (log rank p < 0.0001). This finding was supported in the adjusted multivariate model which showed a 46% increased risk of death for untreated patients in the <70 year olds and a 17% increased risk of death for untreated patients in the ≥70 year olds (vs. treated). Conclusions: In this real-world analysis, 48% of elderly mTNBC patients did not receive chemotherapy and a greater proportion were untreated in the ≥70 year old cohort (55%). Although the survival benefits of chemotherapy were greater in the younger cohort, the benefits of treatment persisted in ≥70 year olds. These findings suggest opportunities exist to improve the clinical treatment of elderly mTNBC patients.

Effect of Astragalus Injection Combined with Chemotherapy on Qual ity of Life in Patients with Advanced Non-small Cell Lung Cancer

Objective: To observe the effect of Astragalus injection (AI) combined with chemotherapy on quality of life (QOF) in patients with advanced non-small cell lung caner (NSCLC). Methods: Sixty NSCLC patients were randomly divided into the treated group (n=30,treated with AI combined with chemotherapy) and the control group (n=30, treated with chemotherapy alone). Chemotherapy of MVP protocol was applied to both groups. AI was supplemented to the treated group by intravenous dripping 60 ml per day. Treatment of 21-28 days consisted one treatment cycle, and 2-3 cycles were applied. WResults: The effective rate in the treated group was 40.0% and in the control group was 36.7%, the mean remission rate in them being 5.4 month s and 3.3 months, the median survival period 11 month and 7 month and the 1-year survival rate 46.75% and 30.0%, respectively, the difference of these indexes between the two groups were all significant (P<0 05). Moreover, the clinical improving rate and QOF elevation rate in the treated group was 80.4% and 43.3%, as compared with those in the control group (50.0% and 23.3% respectively), the different was also significant (P<0 01). Conclusion: AI combined with chemotherapy can significantly improve the QOF in NSCLC patients of advanced stage.

Significance of music therapy in treating depression and anxiety disorders among people with cancer

Globally,cancer cases and mortality have recently escalated and have attracted global concern.The clinical diagnosis and manifestation of cancer can result in significant mental health issues like depression and anxiety disorders.The tendency of people with cancer to suffer from psychological disorders such as anxiety and depression is usually high.A significant number of deaths related to cancer may likely not be from the killer disease but from psychological disorders associated with the illness.The utilization of music as a remedial approach to healing mental disorders cannot be overstated.Thus,identifying the impacts of music therapy in dealing with depression and anxiety disorders among people with cancer is relevant,as the majority of methods used in treating cancer have some side effects which may trigger psychological disorders in cancer patients.Ultimately,this study explored the significance of music therapy in treating depression and anxiety disorders among people with cancer.To achieve the aim of this study,the authors employed a narrative literature review to investigate the significance of music therapy in addressing depression and anxiety disorders among people with cancer.The type of literature review employed in this study is to provide an understanding of the selected research papers.The review found that music therapy significantly reduces depression and anxiety disorders among breast cancer,lung cancer,prostate cancer,and colorectal cancer patients.It is needful for healthcare providers to incorporate music therapy interventions while treating people with cancer.This will help reduce cancer deaths resulting from psychological disorders rather than the killer disease,cancer.However,the standardized procedures and evaluation criteria for applying music-based intervention strategies in oncology medicine still need to be further established and improved.

Quality of life of hospitalized patients after lung cancer operation and analysis of influencing factors

Objective:To explore the current status and influencing factors of quality of life in patients with lung cancer after surgery in a tertiary hospital in Hainan province.Methods:To investigate the influencing factors of quality of life of lung cancer patients after surgery in a tertiary hospital in Hainan province by cross‑sectional survey method.Results:The scores of insomnia,appetite loss,constipation and pain in 186 lung cancer patients after surgery in a tertiary hospital in Hainan Province were significantly higher than the reference value.Multiple linear regression analysis showed that older patients(>60 years)had lower scores in physical function domain(β=-0.193),and female patients had more appetite loss symptoms(β=0.245).Compared with other minority ethnic groups,Han ethnic group had lower scores in role function domain(β=0.179),more severe fatigue symptoms(β=-0.162),and higher general health level(β=0.166).Patients with employee medical insurance had lower scores of emotional function(β=0.194),cognitive function(β=0.281),the lowest score in social function(β=0.188),and severe pain in other parts(β=-0.227).Smokers had less cough symptoms(β=0.175)and more arm and shoulder pain symptoms(β=-0.21)than non‑smokers.Patients with secondhand smoke exposure had lower cognitive function scores(β=-0.158)and more obvious symptoms of oral ulcer(β=0.185).Patients who drank alcohol frequently(drinking frequency>1 time/day)had more severe cough symptoms(β=0.27).Patients with small number of children(0‑1)had milder cough symptoms(β=0.178).Patients who did not understand the disease had obvious symptoms of arm and shoulder pain(β=0.151).Patients with early pathological stage(stageⅠ‑Ⅱ)had more severe shortness of breath(β=-0.159)and pain(β=-0.181).The symptoms of appetite loss were more obvious in patients living in cities(β=0.192).The symptoms of peripheral neuropathy were more obvious(β=0.174).Patients who often consumed pickulated food had severe pain symptoms(β=-0.219),and pain in other parts was obvious(β=-0.149).Male patients had obvious alopecia symptoms(β=-0.306).Conclusion:Age,ethnicity,residence,type of medical insurance,number of children,pathological stage of lung cancer,smoking,second‑hand smoke exposure,alcohol consumption,and frequent consumption of pickled food were related to the quality of life of lung cancer patients in hospital after surgery.Medical staff and family members should pay attention to the emotional communication of patients during the treatment of lung cancer patients in hospital after surgery.Patients should avoid exposure to smoking,alcohol and second‑hand smoke,and reduce consumption of pickled food.

Protective effect of sevoflurane on lung function of elderly chronic obstructive pulmonary disease patients undergoing total hip arthroplasty

BACKGROUND Chronic obstructive pulmonary disease(COPD)is a common respiratory disorder that affects the elderly population and increases the risk of postoperative pulmonary complications(PPCs)after major surgeries.Sevoflurane is a volatile anesthetic that has been shown to have anti-inflammatory and antioxidant properties and attenuate lung injury in animal models.AIM To evaluate the protective effect of sevoflurane on the lung function of elderly COPD patients undergoing total hip arthroplasty(THA).METHODS In this randomized controlled trial,we randomly assigned 120 elderly patients with COPD,who were scheduled for THA,to receive either sevoflurane(sevoflurane group)or propofol(propofol group)as the maintenance anesthetic.The primary outcome was the incidence of PPCs within seven days after surgery.The secondary outcomes were changes in the lung function parameters,inflammatory markers,oxidative stress markers,and postoperative pain scores.RESULTS The results showed that the incidence of PPCs was significantly lower in the sevoflurane group than in the propofol group(10%vs 25%,P=0.02).Furthermore,the decline in the forced expiratory volume in 1 s,forced vital capacity,and peak expiratory flow was significantly lesser in the sevoflurane group than in the propofol group at 24 h and 48 h after surgery(P<0.05).The interleukin-6,tumor necrosis factor-alpha,malondialdehyde,and 8-hydroxy-2α-deoxyguanosine levels were significantly lower in the sevoflurane group than in the propofol group at 24 h after surgery(P<0.05).The sevoflurane group showed significantly lower postoperative pain scores than the propofol group at 6 h,12 h,and 24 h after surgery(P<0.05).CONCLUSION Sevoflurane protects the lung function of elderly COPD patients undergoing THA under general anesthesia by reducing the incidence of PPCs,attenuating inflammatory and oxidative stress responses,and alleviating postoperative pain.
