Investigation and Analysis of Lung Cancer Risk Factors in the Health Check-Up Population

Objective: To investigate and analyze the risk factors of lung cancer in the population of health checkups. Methods: A total of 500 cases of the health check-up population were selected for data study. Surveyed showed that 19 cases of lung cancer were grouped as the lung cancer group and the remaining 481 cases made up the control group, and the risk factors were analyzed. Results: Among men, there was a significant proportion of individuals aged 60-69 years old, and women aged 30-39 years old. Additionally, individuals aged 60 and above were at increased risk of developing lung cancer. The results of the multifactorial analysis were that the risk factors affecting the detection of lung cancer in healthy people were smoking history, family history of lung cancer, secondhand smoke, history of respiratory diseases, psychosomatic factors, living environment, and kitchen fumes. Conclusion: People over 60 years of age were prone to early lung cancer, followed by individuals aged 30-39 years. It is important to identify the risk factors of lung cancer to strengthen the screening of high-risk groups for early detection and treatment.

The mechanism and risk factors for immune checkpoint inhibitor pneumonitis in non-small cell lung cancer patients

Immune checkpoint inhibitors(ICIs)are new and promising therapeutic agents for non-small cell lung cancer(NSCLC).However,along with demonstrating remarkable efficacy,ICIs can also trigger immune-related adverse events.Checkpoint inhibitor pneumonitis(CIP)has been reported to have a morbidity rate of 3%to 5%and a mortality rate of 10%to 17%.Moreover,the incidence of CIP in NSCLC is higher than that in other tumor types,reaching 7%to 13%.With the increased use of ICIs in NSCLC,CIP has drawn extensive attention from oncologists and cancer researchers.Identifying high risk factors for CIP and the potential mechanism of CIP are key points in preventing and monitoring serious adverse events.In this review,the results of our analysis and summary of previous studies suggested that the risk factors for CIP may include previous lung disease,prior thoracic irradiation,and combinations with other drugs.Our review also explored potential mechanisms closely related toCIP,including increasedT cell activity against associated antigens in tumor and normal tissues,preexisting autoantibodies,and inflammatory cytokines.

Trends and risk factors of lung cancer in China

China is faced with heavy burdens caused by lung cancer,which has climbed to the top of both cancer incidence and mortality spectrums.The age-standardized rates of incidence and mortality have shown a trend of gradual uptrends in the last decades,while the crude rates rise much quickly due to the aging of population.Although the improvement in health care has contributed to better survival of lung cancer,its prognosis is still challenging.Apart from the common risk factors such as tobacco use,air pollution,and occupational hazards,some specific factors like Chinese-style cooking also have posed great threats to human health.In light of such national conditions,specific interventions should be conducted to curb the burden of lung cancer including smoking cessation,improvement of air quality,early detection and effective treatment of lung cancer.

Awareness of Lung Cancer Symptoms and Risk Factors in General Population

Introduction: Lung cancer is often diagnosed in a late stage, which might be related to lack of risk factors and symptoms awareness. Aim of this study was to evaluate these factors. Methods: A survey was conducted to assess the awareness of lung cancer risk factors and symptoms. Kruskal-Wallis, Fisher and chi-square tests were used to compare the groups. Results: Altogether 403 participants (108 male;median age 29 (range 13 to 74) years;98 smokers, 90 ex-smokers and 212 non-smokers) completed the survey (321 filled in online questionnaire, 82 were interviewed face-to-face). Three per cent of the respondents were unable to name any lung cancer risk factor, 36% named one and 61% named two or more. Smoking was mentioned most commonly, others far less often. When presented with a list of lung cancer risk factors, 99.7% of respondents recognised two or more;most commonly smoking (99%) and second-hand smoking (95%). Concerning symptoms, 17% were unable to name any, 21% named one and 62% named two or more. Prolonged cough was mentioned most often (59%), followed by dyspnea (45%) and chest pain (30%). When presented with a list, 99% of respondents recognised two or more symptoms;most often prolonged cough (86%), weakness (85%) and chest pain (82%). There were no statistical differences in lung cancer symptom, risk factor or prognosis awareness among smokers, ex-smokers and non-smokers. There were some differences related to age, sex, education and type of used questionnaire. Conclusions: Awareness of lung cancer risks and symptoms is moderate in general population without major differences between smokers and non-smokers.

Study on psychological resilience and associated influencing factors in lung cancer patients with bone metastases

BACKGROUND Evaluating the psychological resilience of lung cancer(LC)patients helps understand their mental state and guides future treatment.However,there is limited research on the psychological resilience of LC patients with bone me-tastases.AIM To explore the psychological resilience of LC patients with bone metastases and identify factors that may influence psychological resilience.METHODS LC patients with bone metastases who met the inclusion criteria were screened from those admitted to the Third Affiliated Hospital of Wenzhou Medical University.The psychological scores of the enrolled patients were collected.They were then grouped based on the mean psychological score:Those with scores lower than the mean value were placed in the low-score group and those with scores equal to or greater than the mean value was placed in the high-score group.The baseline data(age,gender,education level,marital status,residence,monthly income,and religious beliefs),along with self-efficacy and medical coping mode scores,were compared.RESULTS This study included 142 LC patients with bone metastases admitted to our hospital from June 2022 to December 2023,with an average psychological resilience score of 63.24±9.96 points.After grouping,the low-score group consisted of 69 patients,including 42 males and 27 females,with an average age of 67.38±9.55 years.The high-score group consisted of 73 patients,including 49 males and 24 females,with a mean age of 61.97±5.00 years.χ2 analysis revealed significant differences between the two groups in education level(χ2=6.604,P=0.037),residence(χ2=12.950,P=0.002),monthly income(χ2=9.375,P=0.009),and medical coping modes(χ2=19.150,P=0.000).Independent sample t-test showed that the high-score group had significantly higher self-efficacy scores(t=3.383,P=0.001)and lower age than the low-score group(t=4.256,P<0.001).Furthermore,multivariate logistic regression hazard analysis confirmed that self-efficacy is an independent protective factor for psychological resilience[odds ratio(OR)=0.926,P=0.035,95%confidence interval(CI):0.862-0.995],while age(OR=1.099,P=0.003,95%CI:1.034-1.169)and medical coping modes(avoidance vs confrontation:OR=3.767,P=0.012,95%CI:1.342-10.570;resignation vs confrontation:OR=5.687,P=0.001,95%CI:1.974-16.385)were identified as independent risk factors.A predictive model based on self-efficacy,age,and medical coping modes was developed.The receiver operating characteristic analysis showed an area under the curve value of 0.778(95%CI:0.701-0.856,P<0.001),indicating that the model has good predictive performance.CONCLUSION LC patients with bone metastases are less psychologically resilient than the general population.Factors such as self-efficacy,age,and medical coping modes influence their psychological resilience.Patients with low self-efficacy,old age,and avoidance/resignation coping modes should be closely observed.

Analysis of Influencing Factors of Moderate to Severe Malnutrition in Elderly Patients with Lung Cancer during Chemotherapy

Objective:This study aims to identify the factors influencing moderate to severe malnutrition in elderly lung cancer patients undergoing chemotherapy and to provide a basis for developing clinical prevention and intervention strategies.Methods:The clinical data of 150 elderly lung cancer patients who received chemotherapy were retrospectively analyzed.Demographic data,clinical characteristics,laboratory indicators,treatment plans,and other relevant information were collected.Independent risk factors for moderate to severe malnutrition during chemotherapy were identified.Results:During chemotherapy,50 patients(33.33%)developed moderate to severe malnutrition.The BMI of patients with moderate to severe malnutrition was significantly lower than that of patients with no or mild malnutrition(21.20±1.60 vs.26.14±2.31,P<0.001),and the proportion of patients with stage IV tumors was significantly higher(60.00%vs.27.00%,P<0.001).Serum pre-albumin(pre-ALB)and hemoglobin(Hb)levels in patients with moderate to severe malnutrition were significantly lower than those in patients with no or mild malnutrition(152.67±30.41 g/L vs.252.47±51.24 g/L and 102.44±10.09 g/L vs.154.21±15.18 g/L,respectively,P<0.001 for all).Conclusion:Low BMI,decreased serum pre-ALB levels,and decreased serum Hb levels before chemotherapy are independent risk factors for moderate to severe malnutrition in elderly lung cancer patients during chemotherapy.Close clinical attention should be given to these patients,with early intervention measures such as nutritional support to reduce the incidence of malnutrition and improve patients’quality of life and prognosis.

Risk Factors for Lung Cancer in Non-smokers in Xuanwei County of China

Tobacco smoking and some types of occupational exposures have consistently been considered as important etiologic factors of lung cancer in industrial countries. At the First World Conference of Lung Cancer (Wyndwer, 1983), it was stressed that more attention should be paid to finding out the causes of lung cancer in non-smokers.In Xuanwei County, Yunnan Province, annual lung cancer death rate was 27.7 per 100,000 in males, among China's highest, and 25.3 per 100,000 in females, the China's highest. The female's lung cancer death rate in Xuanwei County was even much higher than that of the same period in USA white women (ECACM, 1979; Mulvihill, 1976). Marked district variation in cancer mortality exists within Xuanwei County. The county can be divided into high-, medium- and low-mortality areas. Over 90% of the population arc farmers. The local residents traditionally burned three major kinds of fuels: 'smoky' coal, 'smokeless' coal and 'wood', for heating and cooking. The three lung cancer high mortality areas, including 'Chengguan', 'Rongcheng' and 'Laibin' communes, mainly burned the 'smoky' coal from Laibin smoky-coal mine. The fuel was burned in a shallow, unventilated fire pit in the floor of the dwelling. Fuel burning in shallow unventilated pits has resulted in high indoor air pollution levels. The concentrations of airborne particles (pm 10) inside houses during smoky coal and wood combustion were very high. Indoor concentration of suspended particulates and dichloromethane extractable organics were 24.4mg/m3 and 17.6mg/m3 in burning of 'smoky' coal; 22.3mg/m3, 12.3mg/m3 for burning wood; and 1.8mg/m3, O.Smg/m-1 for burning of smokeless coals. Levels of individual polycyclic aromatic hydrocarbons, including benzo(a)pyrene, were generally highest during burning of smoky coal, intermediate in burning wood, and least in smokeless coal. Women did most household chores, which include starting fire and cooking. Less than 0.2% of females smoked tobacco. The population-based case-control study presented here is to evaluate the influence of factors on the occurrence of lung cancer in non-smoking women in Xuanwei County and to supplement the etiologic factors of lung cancer in Xuanwei County.

Lung cancer risk in never-smokers:An overview of environmental and genetic factors

Lung cancer is the leading cause of cancer-related mortality globally,accounting for 1.8 million deaths in 2020.While the vast majority are caused by tobacco smoking,15%-25%of all lung cancer cases occur in lifelong neversmokers.The International Agency for Research on Cancer(IARC)has classified multiple agents with sufficient evidence for lung carcinogenesis in humans,which include tobacco smoking,as well as several environmental exposures such as radon,second-hand tobacco smoke,outdoor air pollution,household combustion of coal and several occupational hazards.However,the IARC evaluation had not been stratified based on smoking status,and notably lung cancer in never-smokers(LCINS)has different epidemiological,clinicopathologic and molecular characteristics from lung cancer in ever-smokers.Among several risk factors proposed for the development of LCINS,environmental factors have the most available evidence for their association with LCINS and their roles cannot be overemphasized.Additionally,while initial genetic studies largely focused on lung cancer as a whole,recent studies have also identified genetic risk factors for LCINS.This article presents an overview of several environmental factors associated with LCINS,and some of the emerging evidence for genetic factors associated with LCINS.An increased understanding of the risk factors associated with LCINS not only helps to evaluate a never-smoker’s personal risk for lung cancer,but also has important public health implications for the prevention and early detection of the disease.Conclusive evidence on causal associations could inform longer-term policy reform in a range of areas including occupational health and safety,urban design,energy use and particle emissions,and the importance of considering the impacts of second-hand smoke in tobacco control policy.

Analysis of risk factors leading to anxiety and depression in patients with prostate cancer after castration and the construction of a risk prediction model

BACKGROUND Cancer patients often suffer from severe stress reactions psychologically,such as anxiety and depression.Prostate cancer(PC)is one of the common cancer types,with most patients diagnosed at advanced stages that cannot be treated by radical surgery and which are accompanied by complications such as bodily pain and bone metastasis.Therefore,attention should be given to the mental health status of PC patients as well as physical adverse events in the course of clinical treatment.AIM To analyze the risk factors leading to anxiety and depression in PC patients after castration and build a risk prediction model.METHODS A retrospective analysis was performed on the data of 120 PC cases treated in Xi'an People's Hospital between January 2019 and January 2022.The patient cohort was divided into a training group(n=84)and a validation group(n=36)at a ratio of 7:3.The patients’anxiety symptoms and depression levels were assessed 2 wk after surgery with the Self-Rating Anxiety Scale(SAS)and the Selfrating Depression Scale(SDS),respectively.Logistic regression was used to analyze the risk factors affecting negative mood,and a risk prediction model was constructed.RESULTS In the training group,35 patients and 37 patients had an SAS score and an SDS score greater than or equal to 50,respectively.Based on the scores,we further subclassified patients into two groups:a bad mood group(n=35)and an emotional stability group(n=49).Multivariate logistic regression analysis showed that marital status,castration scheme,and postoperative Visual Analogue Scale(VAS)score were independent risk factors affecting a patient's bad mood(P<0.05).In the training and validation groups,patients with adverse emotions exhibited significantly higher risk scores than emotionally stable patients(P<0.0001).The area under the curve(AUC)of the risk prediction model for predicting bad mood in the training group was 0.743,the specificity was 70.96%,and the sensitivity was 66.03%,while in the validation group,the AUC,specificity,and sensitivity were 0.755,66.67%,and 76.19%,respectively.The Hosmer-Lemeshow test showed aχ^(2) of 4.2856,a P value of 0.830,and a C-index of 0.773(0.692-0.854).The calibration curve revealed that the predicted curve was basically consistent with the actual curve,and the calibration curve showed that the prediction model had good discrimination and accuracy.Decision curve analysis showed that the model had a high net profit.CONCLUSION In PC patients,marital status,castration scheme,and postoperative pain(VAS)score are important factors affecting postoperative anxiety and depression.The logistic regression model can be used to successfully predict the risk of adverse psychological emotions.

Risk Factors for Chemotherapy-Induced Leukopenia in Patients with Lung Cancer

Objective: This analysis was conducted to clarify risk factors for chemotherapy-induced leukopenia (CIL) in lung cancer. Methods: A retrospective study was conducted on data from 358 patients with lung cancer who received chemotherapy. Results: Among 358 cases of lung cancer who received chemotherapy, a total of 240 patients experienced CIL, rate was 67%. The demographic data including gender (P = 0.795), age (P = 0.134), presence of selected chronic comorbidities (P = 0.23) were not significantly different in the two groups. The weight loss rate, PS score, sub-normal pre-WBC level, sub-normal pre-PLT level, and the cycle of chemotherapy were significantly different between the groups (P < 0.05). Multivariate analysis revealed that the weight loss rate ≥5% (OR = 0.503), sub-normal pre-WBC level (OR = 11.807), the cycle of chemotherapy ≥3 (OR = 3.100) were main risk factors for CIL in lung cancer. Conclusion: Before treatment, weight loss rate is 5% or higher, chemotherapy has a cycle of 3 or more and sub-normal WBC level is independent risk factor of lung cancer after chemotherapy-induced leucopenia.

Uncovering the epidemiology of bladder cancer in the Arab world: A review of risk factors, molecular mechanisms, and clinical features

Objective:Bladder cancer(BC)is a significant public health concern in the Middle East and North Africa,but the epidemiology and clinicopathology of the disease and contributors to high mortality in this region remain poorly understood.The aim of this systematic review was to investigate the epidemiological features of BC in the Arab world and compare them to those in Western countries in order to improve the management of this disease.Methods:An extensive electronic search of the PubMed/PMC and Cochrane Library databases was conducted to identify all articles published until May 2022,following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.A total of 95 articles were included in the final analysis after title,abstract,and full-text screening,with additional data obtained from the GLOBOCAN and WHO 2020 databases.

Hotspots and trends of risk factors in gastric cancer: A visualization and bibliometric analysis

BACKGROUND The lack of specific symptoms of gastric cancer(GC)causes great challenges in its early diagnosis.Thus it is essential to identify the risk factors for early diagnosis and treatment of GC and to improve the survival rates.AIM To assist physicians in identifying changes in the output of publications and research hotspots related to risk factors for GC,constructing a list of key risk factors,and providing a reference for early identification of patients at high risk for GC.METHODS Research articles on risk factors for GC were searched in the Web of Science core collection,and relevant information was extracted after screening.The literature was analyzed using Microsoft Excel 2019,CiteSpace V,and VOSviewer 1.6.18.RESULTS A total of 2514 papers from 72 countries and 2507 research institutions were retrieved.China(n=1061),National Cancer Center(n=138),and Shoichiro Tsugane(n=36)were the most productive country,institution,or author,respectively.The research hotspots in the study of risk factors for GC are summarized in four areas,namely:Helicobacter pylori(H.pylori)infection,single nucleotide polymorphism,bio-diagnostic markers,and GC risk prediction models.CONCLUSION In this study,we found that H.pylori infection is the most significant risk factor for GC;single-nucleotide polymorphism(SNP)is the most dominant genetic factor for GC;bio-diagnostic markers are the most promising diagnostic modality for GC.GC risk prediction models are the latest current research hotspot.We conclude that the most important risk factors for the development of GC are H.pylori infection,SNP,smoking,diet,and alcohol.

Identifying the risk factors for pancreatic fistula after laparoscopic pancreaticoduodenectomy in patients with pancreatic cancer

BACKGROUND Laparoscopic pancreaticoduodenectomy(LPD)is a surgical procedure for treating pancreatic cancer;however,the risk of complications remains high owing to the wide range of organs involved during the surgery and the difficulty of anastomosis.Pancreatic fistula(PF)is a major complication that not only increases the risk of postoperative infection and abdominal hemorrhage but may also cause multi-organ failure,which is a serious threat to the patient’s life.This study hypothesized the risk factors for PF after LPD.AIM To identify the risk factors for PF after laparoscopic pancreatoduodenectomy in patients with pancreatic cancer.METHODS We retrospectively analyzed the data of 201 patients admitted to the Fudan University Shanghai Cancer Center between August 2022 and August 2023 who underwent LPD for pancreatic cancer.On the basis of the PF’s incidence(grades B and C),patients were categorized into the PF(n=15)and non-PF groups(n=186).Differences in general data,preoperative laboratory indicators,and surgery-related factors between the two groups were compared and analyzed using multifactorial logistic regression and receiver-operating characteristic(ROC)curve analyses.RESULTS The proportions of males,combined hypertension,soft pancreatic texture,and pancreatic duct diameter≤3 mm;surgery time;body mass index(BMI);and amylase(Am)level in the drainage fluid on the first postoperative day(Am>1069 U/L)were greater in the PF group than in the non-PF group(P<0.05),whereas the preoperative monocyte count in the PF group was lower than that in the non-PF group(all P<0.05).The logistic regression analysis revealed that BMI>24.91 kg/m²[odds ratio(OR)=13.978,95%confidence interval(CI):1.886-103.581],hypertension(OR=8.484,95%CI:1.22-58.994),soft pancreatic texture(OR=42.015,95%CI:5.698-309.782),and operation time>414 min(OR=15.41,95%CI:1.63-145.674)were risk factors for the development of PF after LPD for pancreatic cancer(all P<0.05).The areas under the ROC curve for BMI,hypertension,soft pancreatic texture,and time prediction of PF surgery were 0.655,0.661,0.873,and 0.758,respectively.CONCLUSION BMI(>24.91 kg/m²),hypertension,soft pancreatic texture,and operation time(>414 min)are considered to be the risk factors for postoperative PF.

Predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa squamous cell lung cancer:A retrospective analysis

BACKGROUND Lung cancer(LC)is a global medical,social and economic problem and is one of the most common cancers and the leading cause of mortality from malignant neoplasms.LC is characterized by an aggressive course,and in the presence of disease recurrence risk factors,patients,even at an early stage,may be indicated for adjuvant therapy to improve survival.However,combined treatment does not always guarantee a favorable prognosis.In this regard,establishing predictors of LC recurrence is highly important both for determining the optimal treatment plan for the patients and for evaluating its effectiveness.AIM To establish predictors of disease recurrence after radical resection and adjuvant chemotherapy in patients with stage IIb-IIIa lung squamous cell carcinoma(LSCC).METHODS A retrospective case-control cohort study included 69 patients with LSCC who underwent radical surgery at the Orenburg Regional Clinical Oncology Center from 2009 to 2018.Postoperatively,all patients received adjuvant chemotherapy.Histological samples of the resected lung were stained with Mayer's hematoxylin and eosin and examined under a light microscope.Univariate and multivariate analyses were used to identify predictors associated with the risk of disease recurrence.Receiver operating characteristic curves were constructed to discriminate between patients with a high risk of disease recurrence and those with a low risk of disease recurrence.Survival was analyzed using the Kaplan-Meier method.The log-rank test was used to compare survival curves between patient subgroups.Differences were considered to be significant at P<0.05.RESULTS The following predictors of a high risk of disease recurrence in patients with stage IIb-IIa LSCC were established:a low degree of tumor differentiation[odds ratio(OR)=7.94,95%CI=1.08-135.81,P=0.049];metastases in regional lymph nodes(OR=5.67,95%CI=1.09-36.54,P=0.048);the presence of loose,fine-fiber connective tissue in the tumor stroma(OR=21.70,95%CI=4.27-110.38,P=0.0002);and fragmentation of the tumor solid component(OR=2.53,95%CI=1.01-12.23,P=0.049).The area under the curve of the predictive model was 0.846(95%CI=0.73-0.96,P<0.0001).The sensitivity,accuracy and specificity of the method were 91.8%,86.9%and 75.0%,respectively.In the group of patients with a low risk of LSCC recurrence,the 1-,2-and 5-year disease-free survival(DFS)rates were 84.2%,84.2%and 75.8%,respectively,while in the group with a high risk of LSCC recurrence the DFS rates were 71.7%,40.1%and 8.2%,respectively(P<0.00001).Accordingly,in the first group of patients,the 1-,2-and 5-year overall survival(OS)rates were 94.7%,82.5%and 82.5%,respectively,while in the second group of patients,the OS rates were 89.8%,80.1%and 10.3%,respectively(P<0.00001).CONCLUSION The developed method allows us to identify a group of patients at high risk of disease recurrence and to adjust to ongoing treatment.

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.

Analysis of factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19

Objective:To explore factors related to postoperative pulmonary infection in lung cancer patients after recovery from COVID-19 and to provide methods for preventing and reducing the incidence of postoperative lung infection in patients with lung cancer.Methods:A total of 92 patients who underwent lung cancer surgery in the Department of Thoracic and Cardiac Surgery of Yichang Central People’s Hospital from January 28,2023,to March 3,2023,were selected.They were divided into a pulmonary infection group(47 cases)and a nonpulmonary infection group(45 cases)according to whether pulmonary infection occurred.General clinical data of patients were collected and collated to analyse the related influencing factors of pulmonary infection in lung cancer patients after recovery from COVID-19.Results:Univariate analysis showed that patient age(≥60 years),fever after COVID-19 infection,oral and laryngeal symptoms,digestive tract symptoms,neurological symptoms,long-term smoking history,hypertension history,and operation time(≥3 h)were correlated with pulmonary infection(all P<0.05).There was no significant correlation between postoperative pulmonary infection and sex,ocular,nasal and tongue symptoms,systemic symptoms,duration of COVID-19,COPD,lobectomy site,incision pain,mechanical ventilation time(≥6 h),drainage tube retention time(3 d),surgical method(P>0.05).Logistic multivariate analysis showed that age(≥60 years old),long operation time(≥3 h)and long-term smoking history were independent influencing factors for postoperative pulmonary infection in patients with radical resection of lung cancer(P>0.05).Conclusion:In this study,older age(≥60 years old),long-term smoking history,and long operation time(≥3 h)were risk factors for pulmonary infection after lung cancer surgery.In the future,active treatment measures can be taken to address these risk factors during the perioperative period to reduce the incidence of postoperative pulmonary infection.

Clinical Features and Prognostic Factors of Small Cell Lung Cancer:A Retrospective Study in 148 Patients

To better understand the outcomes of small cell lung cancer（SCLC）,we examined the clinical features and prognostic factors of SCLC in this study.A total of 148 patients who were diagnosed as having SCLC between January 2009 and December 2013 in Cancer Center of Union Hospital,Wuhan,China,were enrolled and their clinical features and prognostic factors were retrospectively analyzed.Log-rank test and Cox regression model were employed for analysis of prognostic factors.The 1-and 2-year overall survival（OS） rates were 59.7% and 25.7%,respectively,for limited disease（LD） patients whose median survival time（MST） was 16 months.The 1-and 2-year OS rates were 29.5% and 5.3%,respectively,for extensive disease（ED） patients whose MST was 10 months.The univariate analysis and multivariate analysis revealed that age,tumor stage,serum CEA and Ki-67 antigen were significantly correlated to the outcomes of SCLC,and they were significant prognostic factors for SCLC.

Insomnia Burden among Informal Caregivers of Hospitalized Lung Cancer Patients and Its Influencing Factors

Objective This study aimed to reveal the insomnia burden and relevant influencing factors among informal caregivers(ICs)of hospitalized patients with lung cancer.Methods A cross-sectional study on ICs of hospitalized patients with lung cancer was conducted from December 31,2020 to December 31,2021.ICs’burden was assessed using the Caregiver Reaction Assessment(CRA),Hospital Anxiety and Depression Scale(HADS),and Insomnia Severity Index(ISI).Linear and logistic regression models were used to identify the influencing factors.Results Among 289 ICs of hospitalized patients with lung cancer,83(28.72%),53(18.34%),and 14(4.84%)ICs experienced mild,moderate,and severe insomnia,respectively.The scores concerning self-esteem,lack of family support,financial problems,disturbed schedule,and health problems were 4.32±0.53,2.24±0.79,2.84±1.14,3.63±0.77,and 2.44±0.95,respectively.ICs with higher Activities of Daily Living Scale(ADLS)scores were associated with a lower risk of insomnia,with an odd ratio(OR)and 95%confidence interval(CI)of 0.940(0.898–0.983).Among the ICs,female gender(OR=2.597),alcohol consumption(OR=3.745),underlying medical conditions(OR=11.765),long-term caregiving experience(OR=37.037),and higher monthly expenses(OR=5.714)were associated with a high risk of insomnia.Conclusion Of the hospitalized patients with lung cancer,51.9%experienced insomnia.Patients’ADL,ICs gender,alcohol consumption,underlying medical conditions,caregiving duration,and monthly expenses were influencing factors.Therefore,prompt screening and early intervention for ICs of patients with lung cancer is necessary.
