Influence of humanistic care-based operating room nursing on safety,recovery,and satisfaction after radical surgery for colorectal carcinoma

BACKGROUND Radical surgery is a preferred treatment for colorectal carcinoma,wherein nursing intervention is essential for postoperative recovery and prevention of complications.Recently,the application of humanistic care in medical care has attracted attention.Humanistic care emphasizes comprehensive care,with importance attached to patients’physical needs as well as psychological and emotional support to provide more humane and personalized care services.However,no clinical reports have examined the use of humanistic care in patients undergoing radical surgery for colorectal carcinoma.AIM To investigate the influence of humanistic care-based operating room nursing on the safety,postoperative recovery,and nursing satisfaction of patients who have undergone radical surgery for colorectal carcinoma.METHODS In total,120 patients with rectal cancer who underwent surgery in Zhongnan Hospital of Wuhan University between August 2023 and March 2024 were selected and grouped based on the nursing methods employed.Of these patients,55 were treated with routine nursing intervention(control group)and 65 were provided humanistic care-based operating room nursing(research group).The patients’vital signs were recorded,including systolic/diastolic blood pressure(SBP/DBP)and heart beats per minute(BPM),as well as serum stress indices,including norepinephrine(NE),adrenal hormone(AD),and cortisol(Cor).Postoperative recovery and complications were also recorded.Patients’negative emotions,life hope,and nursing satisfaction were evaluated using the Self-rating Depression/Anxiety Scale(SDS/SAS),Herth Hope Index(HHI),and self-deve-loped nursing satisfaction questionnaire,respectively.RESULTS During emergence from anesthesia,SBP,DBP,and BPM levels were found to be lower in the research group than those in the control group,also serum Cor,AD,and NE levels were lower.In addition,the research group had shorter operative,awakening,anal exhaust,first postoperative ambulation,drainage tube removal,intestinal recovery,and hospital times.The total complication rate and the SDS and SAS scores were lower in the research group than those in the control group.The HHI and nursing satisfaction scores were higher in the research group.CONCLUSION Humanistic care-based operating room nursing can mitigate physiological stress responses,reduce postoperative complications,promote postoperative recovery,relieve adverse psychological emotions,and enhance life hope and nursing satisfaction in patients undergoing radical surgery for colorectal carcinoma,which can be popularized in clinical practice.

Recurrence risk model for esophageal cancer after radical surgery

Objective：The aim of the present study was to construct a risk assessment model which was tested by disease-free survival （DFS） of esophageal cancer after radical surgery.Methods：A total of 164 consecutive esophageal cancer patients who had undergone radical surgery between January 2005 and December 2006 were retrospectively analyzed.The cutpoint of value at risk （VaR） was inferred by stem-and-leaf plot,as well as by independent-samples t-test for recurrence-free time,further confirmed by crosstab chi-square test,univariate analysis and Cox regression analysis for DFS.Results：The cutpoint of VaR was 0.3 on the basis of our model.The rate of recurrence was 30.3 ％ （30/99）and 52.3％ （34/65） in VaR ＜0.3 and VaR ＞0.3 （chi-square test,x2 =7.984,P=0.005）,respectively.The 1-,3-,and 5-year DFS of esophageal cancer after radical surgery was 70.4％,48.7％,and 45.3％,respectively in VaR ＞≥0.3,whereas 91.5％,75.8％,and 67.3％,respectively in VaR ＜0.3 （Log-rank test,x2 =9.59,P=0.0020）,and further confirmed by Cox regression analysis [hazard ratio =2.10,95 ％ confidence interval （CI）：1.2649-3.4751; P=0.0041].Conclusions：The model could be applied for integrated assessment of recurrence risk after radical surgery for esophageal cancer.

Primary Treatment for Clinically Early Cervical Cancer with Lymph Node Metastasis:Radical Surgery or Radiation?

Objective To compare survival outcomes between primary radical surgery and primary radiation in early cervical cancer.Methods Patient information was extracted from the Surveillance,Epidemiology,and Results database.Patients diagnosed with early cervical cancer of stage T1a,T1b,and T2a(American Joint Committee on Cancer,7th edition)from 1998 to 2015 were included in this study after propensity score matching.Overall survival(OS)was analyzed using the Kaplan-Meier method.Results Among the 4964 patients included in the study,1080 patients were identified as having positive lymph nodes(N1),and 3884 patients were identified as having negative lymph nodes(N0).Patients with primary surgery had significantly longer 5-year OS than those with primary radiotherapy in both the N1 group(P<0.001)and N0 group(P<0.001).In the subgroup analysis,similar results were found in patients with positive lymph nodes of stage T1a(100.0%vs.61.1%),T1b(84.1%vs.64.3%),and T2a(74.4%vs.63.8%).In patients with T1b1 and T2a1,primary surgery resulted in longer OS than primary radiation,but not in patients with T1b2 and T2a2.In multivariate analysis,the primary treatment was identified as an independent prognostic factor in both N1 and N0 patients(HR_(N1)=2.522,95%CI=1.919–3.054,PN1<0.001;HR_(N0)=1.895,95%CI=1.689–2.126,PN0<0.001).Conclusion In early cervical cancer stage T1a,T1b1,and T2a1,primary surgery may result in longer OS than primary radiation for patients with and without lymph node metastasis.

ADJUVANT CHEMOTHERAPY FOLLOWING RADICAL SURGERYFOR NON-SMALL CELL LUNG CANCER:A RANDOMIZED STUDY

Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage I–III) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX) 300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 dl, cisplatin (DDP) 20 mg/m2, d1–5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600–900 mg/d for 1 year (adjuvant chemotherapy group). The other 35 patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4% in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage III was 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage I–II in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage III, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

The Application of Forward Control Nursing in Anesthesia, Recovery, and Rehabilitation of Thoracoscopic Lung Cancer Radical Surgery

Objective: To explore the clinical application effect of formulating the operating room nursing work procedure sheet for elderly lung cancer patients in thoracoscopic radical surgery. Methods: A total of 85 elderly patients with lung cancer treated in our hospital from May 2022 to May 2023 were included as the study population for this research. They were divided into a study group of 42 cases and a regular group of 43 cases. The regular group of elderly patients received routine nursing care, while the study group of elderly patients was provided with the operating room nursing care work procedure sheet. The surgical duration, intraoperative blood loss, time to mobilization, and postoperative complication rate were compared and analyzed between the two groups. Results: Compared to the regular group, the study group had significantly shorter surgical duration and time to mobilization, as well as less intraoperative blood loss (P < 0.05). The overall incidence of postoperative complications in the study group (4.76%) was significantly lower than that in the regular group (19.05%) (P Conclusion: Formulating the operating room nursing work procedure sheet for elderly lung cancer patients can effectively improve surgical efficiency, reduce the incidence of postoperative complications, and promote patient prognosis in thoracoscopic radical surgery. Therefore, this model is worth promoting and adopting in clinical practice.

Onset and prognostic features of anastomotic leakage in patients undergoing radical surgery after neoadjuvant chemoradiation for rectal cancer

BACKGROUND Anastomotic leakage(AL)is a significant complication of rectal cancer surgery,particularly in patients undergoing neoadjuvant chemoradiotherapy.This study aimed to evaluate the onset and prognostic factors influencing AL in these patients and provide insights for better postoperative management.AIM To explore AL incidence in patients who underwent neoadjuvant radiotherapy for rectal cancer and evaluate influencing factors and prognosis.METHODS We retrospectively analyzed data of patients with rectal cancer who underwent neoadjuvant chemoradiotherapy post-radical surgery admitted to our hospital from January 2020 to January 2023.Postoperative AL was recorded in all patients.Among 63 patients with AL initially enrolled,2 were lost to follow-up;thus,61 patients were included in the incident group.Another 59 patients without AL were included in the non-incident group.Clinical characteristics of both groups were analyzed to identify factors affecting postoperative AL and determine prognosis.RESULTS Multivariate analysis revealed that sex,operative time,bleeding,pelvic radiation injury,and intraoperative blood transfusion were independent risk factors for postoperative AL(P<0.05).The Swiss Institute for Experimental Cancer Research(ISREC)grades for patients with postoperative AL were mainly A(49.18%)and B(40.98%),and most leakages occurred in the posterior wall(65.57%).Clinical manifestations included anal sacrococaudal pain(29.51%),anal pus(26.23%),and other symptoms.Invasive interventions were performed<2 times in 80.33%of patients.Poor prognoses were mainly associated with chronic pressacral sinus formation(24.59%),anastomotic stenosis(29.51%),and long-term stoma(19.67%).Multivariate analysis revealed distance from the anal margin and ISREC grade as independent risk factors for poor prognosis following AL(P<0.05).CONCLUSION Sex,operative time,bleeding loss,pelvic radiation damage,and intraoperative blood transfusion are independent risk factors for AL and the distance between tumor and ISREC grade potentially affect prognosis.

Application value of dexmedetomidine in anesthesia for elderly patients undergoing radical colon cancer surgery

BACKGROUND Colon cancer presents a substantial risk to the well-being of elderly people worldwide.With advancements in medical technology,surgical treatment has become the primary approach for managing colon cancer patients.However,due to age-related physiological changes,especially a decline in cognitive function,older patients are more susceptible to the effects of surgery and anesthesia,increasing the relative risk of postoperative cognitive dysfunction(POCD).There-fore,in the surgical treatment of elderly patients with colon cancer,it is of pa-ramount importance to select an appropriate anesthetic approach to reduce the occurrence of POCD,protect brain function,and improve surgical success rates.METHODS One hundred and seventeen patients with colon cancer who underwent elective surgery under general anesthesia were selected and divided into two groups:A and B.Group A received Dex before anesthesia induction,and B group received an equivalent amount of normal saline.Changes in the mini-mental state exami-nation,regional cerebral oxygen saturation(rSO2),bispectral index,glucose uptake rate(GluER),lactate production rate(LacPR),serum S100βand neuron-specific enolase(NSE),POCD,and adverse anesthesia reactions were compared between the two groups.RESULTS Surgical duration,duration of anesthesia,and intraoperative blood loss were comparable between the two groups(P>0.05).The overall dosage of anesthetic drugs used in group A,including propofol and remifentanil,was significantly lower than that used in group B(P<0.05).Group A exhibited higher rSO2 values at the time of endotracheal intubation,30 min after the start of surgery,and immediately after extubation,higher GluER values and lower LacPR values at the time of endotra-cheal intubation,30 min after the start of surgery,immediately after extubation,and 5 min after extubation(P<0.05).Group A exhibited lower levels of serum S100βand NSE 24 h postoperatively and a lower incidence of cognitive dysfunction on the 1st and 5th postoperative days(P<0.05).CONCLUSION The use of Dex in elderly patients undergoing radical colon cancer surgery helps maintain rSO2 Levels and reduce cerebral metabolic levels and the incidence of anesthesia-and surgery-induced cognitive dysfunction.

Adjuvant chemotherapy following radical surgery for non-small-cell lung cancer: a randomized study on 70 patients

To evaluate the efficacy of adjuvantchemotherapy after radical surgery for non-small-celllung cancer (NSCLC). Methods Seventy patients with NSCLC (stages Ⅰ -Ⅲ ) undergoing radical surgery were randomized intotwo groups. Group 1 (n = 35): combination group,which received adjuvant chemotherapy withcyclophosphamide 300 mg/m 2, vincristine 1. 4 mg/m 2,adriamycin 50 mg/m 2, and lomustine 50 mg/m 2 on day1, and cisplatin 20 mg/m 2 on days 1-5. Thetreatment was repeated every 4-6 weeks for 4 cycles,followed by oral administration of ftorafur (FT-207) 600-900 mg/d for 1 year. Group 2 (n = 35): surgerygroup, which received surgical treatment only. Results The overall 5-year survival rate was 48.6%in the combination group versus 31 .4% in the surgerygroup, and difference between the two groups was notStatistically significant (x 2 = 3.09, P > 0.05). The year survival rate for patients with stage Ⅲ diseasewas 44% and 20.8% in the combination and surgerygroups, respectively, showing a statistically significantdifference (x 2 = 5.28, P < 0.025). The 5-yearsurvival rates of patients in stages Ⅰ -Ⅱ in the twogroups were 60.0% and 54.5%, respectively, andwere not significantly different (x 2 = 0. 03, P > 0. 75). Conclusion Postoperative adjuvant chemotherapy provides statistically significant improvement in the 5 year survival rate only in patients with stage ⅢNSCLC.

A new membrane anatomy-oriented classification of radical surgery for rectal cancer

For patients with different clinical stages of rectal cancer,tailored surgery is urgently needed.Over the past 10 years,our team has conducted numerous anatomical studies and proposed the“four fasciae and three spaces”theory to guide rectal cancer surgery.Enlightened by the anatomical basis of the radical hysterectomy classification system of Querleu and Morrow,we proposed a new classification system of radical surgery for rectal cancer based on membrane anatomy.This system categorizes the surgery into four types(A–D)and incorporates corresponding subtypes based on the preservation of the autonomic nerve.Our surgical classification unifies the pelvic membrane anatomical terminology,validates the feasibility of classifying rectal cancer surgery using the theory of“four fasciae and three spaces,”and lays the theoretical groundwork for the future development of unified and standardized classification of radical pelvic tumor surgery.

MANAGEMENT OF THE ORBITAL CONTENTS IN RADICAL SURGERY FOR SQUAMOUS CELL CARCINOMA OF THE MAXILLARY SINUS

We reviewed retrospectively 139 patients with squamous cell carcinoma of the maxillary sinus who were treated with planned combinations of preoperative radiotherapy and maxillectomy between 1958 and 1987. The 5-year survival rate of these patients was 30%. In 111 patients who had tumor invasion of the orbital floor 88 underwent radical surgery with orbital exenteration and 23 had their orbital contents preserved. If orbital exenteration was performed, the 5-year survival rate was 27.3% (24 / 88) and the rate of recurrence within the orbit was 12.5%. In patients with preservation of the orbital contents, the corresponding rates were 34.8% (8 / 23) and 8.6% respectively (P = 0.65). Histological study af ter maxillectomy with orbital exenteration showed that in 95% of 65 specimens (62 / 65) invasion of the orbit was limited. These tumors could be completely resected by total maxillectomy with limited removal of the periorbital tissues after preoperative radiotherapy. We conclude that after preoperative radiation, the eyeball could be safely preserved in most selected patients with maxillary sinus carcinoma invading the orbital floor.

Outcome of penile prosthesis implantation： are malleable prostheses an appropriate treatment option in patients with erectile dysfunction caused by prior radical surgery？

The aim of our study was to evaluate the outcome of penile prosthesis implantation in patients with various comorbidities as a cause of erectile dysfunction （ED）. The data of 181 patients who underwent surgery between 1998 and 2012 in two centers were evaluated. The mean age of the patients was 52.2 years （range： 31-71 years）. The study group contained 162 patients （89.5%） with malleable prostheses and 19 （10.5%） with inflatable implants. All patients were re-evaluated 1 month later to assess prosthesis function and complications, and further re-examinations were performed if needed. Satisfaction was defined as having satisfactory intercourse and happiness with the device in general. The follow-up period was at least 12 months for each patient. The postoperative complication rate was 32% （n = 58）. The number of complications with inflatable and malleable prostheses was 7 （3.9%） and 51 （28.1%）, respectively. Overall, 21 prostheses （11.6%） had to be removed because of various complications and patient dissatisfaction. Patients with prior radical surgery had higher extraction rates （n = 14.606, P 〈 0.05, Chi-square test）. The main reasons for removal were erosion （n = 11; 6.1%） and infection （n = 3; 2.1%）. With respect to satisfaction during intercourse, we found that 104 （57.5%） patients described themselves as very satisfied with the prosthesis, while 21 （11.6%） were unsatisfied. The high explantation rate in patients with prior surgery was remarkable in our study. Our results revealed that a malleable prosthesis should not be the preferred type of implant for patients with prior surgery.

Stage Ⅱ Pancreatic Cancer: Radical, Palliative Surgery or Stenting?

Background: Pancreatic ductal adenocarcinoma is the fourth most common reason of death among oncological diseases with ever increasing mortality. At the time of diagnosis, patients are usually suitable for three ways of treatment: radical, palliative surgery or stenting. Deciding the best option depends on clinical situation, but is still a matter of debate. Methods: We performed a retrospective research of patients with stage II pancreatic head cancer treated in our clinic between years 2002-2014. Four groups were formed according to the used treatment method: group A: radical surgery with R0 (microscopic tumour clearance) margin;group B: radical surgery with R1 (presence of tumour cells within 1 mm of the resection margin) margin;group C: biliary tract stenting;group D: biliodigestive anastomosis. Clinical data and most importantly the survival of these patients were compared. Results: 200 patients were involved in the final analysis, 82 (41%) of them were IIA and 118 (59%) were IIB. Group A consisted of 113 patients;group B consisted of 28 patients;group C consisted of 33 patients;group D consisted of 26 patients. In patients with IIA stage, group A had the highest survival rate compared with other groups, mean survival was 3.242 versus 1.600;0.454;0.652 years. Patients with IIB stage of cancer similarly had longer survival in group A versus other groups, 1.720 versus 0.931;0.713;0.957 years. Conclusions: Patients with IIA and IIB stage of pancreatic cancer benefit the most from radical surgery with R0 margin. However, for patients with lymph node involvement (stage IIB) and when achieving R0 margin is hardly possible, neoadjuvant treatment seems promising, but we need further randomized controlled trials to fully confirm its effectiveness.

Impact of dexmedetomidine-assisted anesthesia in elderly patients undergoing radical resection of colon cancer

BACKGROUND Radical resection of colon cancer under general anesthesia is one of the main treatment methods for this malignancy.However,due to the physiological charac-teristics of elderly patients,the safety of perioperative anesthesia needs special attention.As anα2-adrenergic receptor agonist,dexmedetomidine(Dex)has attracted much attention from anesthesiologists due to its stabilizing effect on heart rate and blood pressure,inhibitory effect on inflammation,and sedative and analgesic effects.Its application in general anesthesia may have a positive impact on the quality of anesthesia and postoperative recovery in elderly patients undergoing radical resection of colon cancer.METHODS A total of 165 colon cancer patients who underwent radical surgery for colon cancer under general anesthesia at Qingdao University Affiliated Haici Hospital,Qingdao,China were recruited and divided into two groups:A and B.In group A,Dex was administered 30 min before surgery,while group B received an equivalent amount of normal saline.The hemodynamic changes,pulmonary compliance,airway pressure,inflammatory factors,confusion assessment method scores,Ramsay Sedation-Agitation Scale scores,and cellular immune function indicators were compared between the two groups.RESULTS Group A showed less intraoperative hemodynamic fluctuations,better pulmonary compliance,and lower airway resistance compared with group B.Twelve hours after the surgery,the serum levels of TLR-2,TLR-4,IL-6,and TNF-αin group A were significantly lower than those of group B(P<0.05).After extubation,the Ramsay Sedation-Agitation Scale score of group A patients was significantly higher than that of group B patients,indicating a higher level of sedation.The incidence of delirium was significantly lower in group A than in group B(P<0.05).CONCLUSION The use of Dex as an adjunct to general anesthesia for radical surgery in elderly patients with colon cancer results in better effectiveness of anesthesia.

Laparoscopic vs open surgery for gastric cancer: Assessing time, recovery, complications, and markers

BACKGROUND Gastric cancer(GC)is one of the most common cancers worldwide.Morbidity and mortality have increased in recent years,making it an urgent issue to address.La-paroscopic radical surgery(LRS)is a crucial method for treating patients with GC;However,its influence on tumor markers is still under investigation.The data of 194 patients treated at Chongqing University Cancer Hospital bet-ween January 2018 and January 2019 were retrospectively analyzed.Patients who underwent traditional open surgery and LRS were assigned to the control(n=90)and observation groups(n=104),respectively.Independent sample t-tests andχ2 tests were used to compare the two groups based on clinical efficacy,changes in tumor marker levels after treatment,clinical data,and the incidence of posto-perative complications.To investigate the association between tumor marker levels and clinical efficacy in patients with GC,three-year recurrence rates in the two groups were compared.RESULTS Patients in the observation group had a shorter duration of operation,less in-traoperative blood loss,an earlier postoperative eating time,and a shorter hospital stay than those in the control group(P<0.05).No significant difference was observed between the two groups regarding the number of lymph node dissections(P>0.05).After treatment,the overall response rate in the control group was significantly lower than that in the observation group(P=0.001).Furthermore,after treatment,the levels of carbohydrate antigen 19-9,cancer antigen 72-4,carcinoembryonic antigen,and cancer antigen 125 decreased significantly.The observation group also exhibited a significantly lower incidence rate of postoperative complications compared to the control group(P<0.001).Additionally,the two groups did not significantly differ in terms of three-year survival and recurrence rates(P>0.05).CONCLUSION LRS effectively treats early gastric cancer by reducing intraoperative bleeding,length of hospital stays,and postoperative complications.It also significantly lowers tumor marker levels,thus improving the short-term prognosis of the disease.

Therapeutic effects of Buzhong Yiqi decoction in patients with spleen and stomach qi deficiency after routine surgery and chemotherapy for colorectal cancer

BACKGROUND According to the theory of traditional Chinese medicine(TCM),the spleen and stomach are the basis of acquired nature and the source of qi and blood biochemistry.After surgery and chemotherapy,patients with colorectal cancer often develop spleen and stomach qi deficiency syndrome,leading to decreased immune function.Buzhong Yiqi decoction,a classic TCM prescription,has the effect of tonifying middle-jiao and invigorating qi,boosting Yang,and suppressing immune-related inflammation.Moreover,it is widely used in the treatment of spleen and stomach qi deficiency syndrome.AIM To investigate the effect of Buzhong Yiqi decoction on spleen and stomach qi deficiency in patients with colorectal cancer.METHODS One hundred patients with colorectal cancer who underwent preoperative chemotherapy and laparoscopy at The First TCM Hospital of Changde from January 2022 to October 2023 were retrospectively analyzed.The patients were divided equally into control and observation groups.Both groups underwent conventional rehabilitation surgery,and the observation group was supplemented with Buzhong Yiqi decoction.SPSS 26.0 was used for statistical analyses.Theχ2 test was used for univariate analysis;independent sample t-tests were used in all cases.RESULTS No significant differences were observed preoperatively in the general characteristics of the two groups.Fourteen days post-surgery,the abdominal distension,emaciation,loose stool,loss of appetite,and vomiting scores were significantly lower in the observation group than in the control group(P<0.05).Immune function and interleukin(IL)-10 levels in the observation group were significantly higher than those of the control group,whereas IL-6,tumor necrosis factor-α,and C-reactive protein levels,tumor biological indexes,and adverse reactions in the observation group were significantly lower than those of the control group(P<0.05).One month after surgery,the patients’quality of life in the observation group was significantly higher than that of the patients in the control group(P<0.05).CONCLUSION Buzhong Yiqi decoction can regulate inflammatory responses and metabolic processes by enhancing immune function,thereby promoting overall immune nutrition and restoring the body’s balance.

Effects of psychological intervention on negative emotions and psychological resilience in breast cancer patients after radical mastectomy

Breast cancer(BC)is the most common malignant tumor in women,and the treatment process not only results in physical pain but also significant psychological distress in patients.Psychological intervention(PI)has been recognized as an important approach in treating postoperative psychological disorders in BC patients.It has been proven that PI has a significant therapeutic effect on postoperative psychological disorders,improving patients'negative emotions,enhancing their psychological resilience,and effectively enhancing their quality of life and treatment compliance.

Risk factors and survival prediction model establishment for prognosis in patients with radical resection of gallbladder cancer

BACKGROUND Gallbladder cancer(GBC)is the most common malignant tumor of the biliary system,and is often undetected until advanced stages,making curative surgery unfeasible for many patients.Curative surgery remains the only option for long-term survival.Accurate postsurgical prognosis is crucial for effective treatment planning.tumor-node-metastasis staging,which focuses on tumor infiltration,lymph node metastasis,and distant metastasis,limits the accuracy of prognosis.Nomograms offer a more comprehensive and personalized approach by visually analyzing a broader range of prognostic factors,enhancing the precision of treatment planning for patients with GBC.AIM A retrospective study analyzed the clinical and pathological data of 93 patients who underwent radical surgery for GBC at Peking University People's Hospital from January 2015 to December 2020.Kaplan-Meier analysis was used to calculate the 1-,2-and 3-year survival rates.The log-rank test was used to evaluate factors impacting prognosis,with survival curves plotted for significant variables.Single-factor analysis revealed statistically significant differences,and multivariate Cox regression identified independent prognostic factors.A nomogram was developed and validated with receiver operating characteristic curves and calibration curves.Among 93 patients who underwent radical surgery for GBC,30 patients survived,accounting for 32.26%of the sample,with a median survival time of 38 months.The 1-year,2-year,and 3-year survival rates were 83.87%,68.82%,and 53.57%,respectively.Univariate analysis revealed that carbohydrate antigen 19-9 expre-ssion,T stage,lymph node metastasis,histological differentiation,surgical margins,and invasion of the liver,ex-trahepatic bile duct,nerves,and vessels(P≤0.001)significantly impacted patient prognosis after curative surgery.Multivariate Cox regression identified lymph node metastasis(P=0.03),histological differentiation(P<0.05),nerve invasion(P=0.036),and extrahepatic bile duct invasion(P=0.014)as independent risk factors.A nomogram model with a concordance index of 0.838 was developed.Internal validation confirmed the model's consistency in predicting the 1-year,2-year,and 3-year survival rates.CONCLUSION Lymph node metastasis,tumor differentiation,extrahepatic bile duct invasion,and perineural invasion are independent risk factors.A nomogram based on these factors can be used to personalize and improve treatment strategies.

Risk factors for anastomotic fistula development after radical colon cancer surgery and their impact on prognosis

BACKGROUND Colon cancer is a common malignant tumor in the gastrointestinal tract that is typically treated surgically.However,postradical surgery is prone to complic-ations such as anastomotic fistulas.AIM To investigate the risk factors for postoperative anastomotic fistulas and their impact on the prognosis of patients with colon cancer.METHODS We conducted a retrospective analysis of 488 patients with colon cancer who underwent radical surgery.This study was performed between April 2016 and April 2019 at a tertiary hospital in Wuxi,Jiangsu Province,China.A t-test was used to compare laboratory indicators between patients with and those without postoperative anastomotic fistulas.Multiple logistic regression analysis was performed to identify independent risk factors for postoperative anastomotic fistulas.The Functional Assessment of Cancer Therapy-Colorectal Cancer was also used to assess postoperative recovery.RESULTS Binary logistic regression analysis revealed that age[odds ratio(OR)=1.043,P=0.015],tumor,node,metastasis stage(OR=2.337,P=0.041),and surgical procedure were independent risk factors for postoperative anastomotic fistulas.Multiple linear regression analysis showed that the development of postoperative anastomotic fistula(P=0.000),advanced age(P=0.003),and the presence of diabetes mellitus(P=0.015),among other factors,independently affected CONCLUSION Postoperative anastomotic fistulas significantly affect prognosis and survival rates.Therefore,focusing on the clinical characteristics and risk factors and immediately implementing individualized preventive measures are important to minimize their occurrence.

Effect of ultrasound-guided lumbar square muscle block on stress response in patients undergoing radical gastric cancer surgery

BACKGROUND Radical surgery is a common treatment for patients with gastric cancer;however,it can lead to postoperative complications and intestinal barrier dysfunction.Ultrasound-guided quadratus lumborum block is often used for postoperative analgesia,but its effects on stress response and intestinal barrier function are not well understood.AIM To investigate the effects of an ultrasound-guided quadratus lumborum block on stress response and intestinal barrier function in patients undergoing radical surgery for gastric cancer.METHODS A total of 100 patients undergoing radical surgery for gastric cancer were randomly categorized into observation and control groups.Plasma adrenaline and cortisol levels,intestinal mucosal barrier indexes,and complication rates were compared between the two groups before,during,and 1 day after surgery.RESULTS The observation group had significantly lower plasma adrenaline and cortisol levels during surgery and at 1 day postoperatively than that of the control group(P<0.05).Additionally,intestinal barrier indexes(endotoxin and D-dimer)at 1 day postoperatively were significantly lower in the observation group than in the control group(P<0.05).CONCLUSION Ultrasound-guided quadratus lumborum block could reduce stress response,protect intestinal barrier function,and decrease the incidence of complications in patients undergoing radical surgery for gastric cancer.This technique has the potential for clinical applications.

New classification system for radical rectal cancer surgery based on membrane anatomy

BACKGROUND Total mesorectal excision along the“holy plane”is the only radical surgery for rectal cancer,regardless of tumor size,localization or even tumor stage.However,according to the concept of membrane anatomy,multiple fascial spaces around the rectum could be used as the surgical plane to achieve radical resection.AIM To propose a new membrane anatomical and staging-oriented classification system for tailoring the radicality during rectal cancer surgery.METHODS A three-dimensional template of the member anatomy of the pelvis was established,and the existing anatomical nomenclatures were clarified by cadaveric dissection study and laparoscopic surgical observation.Then,we suggested a new and simple classification system for rectal cancer surgery.For simplification,the classification was based only on the lateral extent of resection.RESULTS The fascia propria of the rectum,urogenital fascia,vesicohypogastric fascia and parietal fascia lie side by side around the rectum and form three spaces(medial,middle and lateral),and blood vessels and nerves are precisely positioned in the fascia or space.Three types of radical surgery for rectal cancer are described,as are a few subtypes that consider nerve preservation.The surgical planes of the proposed radical surgeries(types A,B and C)correspond exactly to the medial,middle,and lateral spaces,respectively.CONCLUSION Three types of radical surgery can be precisely defined based on membrane anatomy,including nerve-sparing procedures.Our classification system may offer an optimal tool for tailoring rectal cancer surgery.
