Objective:To conduct meta analysis to compare the effect of complete resection with or without postoperative radiotherapy (PORT) on survival in stage Ⅲ(N 2) non-small cell lung cancer (NSCLC). Methods:Relevant studies of the efficacy of PORT for stage Ⅲ(N 2) NSCLC were searched from Wanfang Data, PubMed, and Cochrane Library from January 2006 to January 2022. Literature screening, extraction of information and assessment of the risk of bias of the included literature was carried out by two independent researchers. Meta analysis was performed using R4.0.3 software. Results:A total of 12 publications consisting of 2992 patients were included, 1479 cases in the PORT group and 1513 cases in the control group. PORT improved the overall survival (OS) and disease free survival (DFS) compared to the control group. Fixed-effects model meta analysis of 6 randomized controlled trials showed that PORT did not significantly reduce the risk of death ( HR=0.98, 95% CI: 0.80-1.20). Fixed-effects model meta analysis of 6 retrospective studies showed that PORT improved prognosis ( HR=0.68, 95% CI: 0.59-0.79). PORT could improve OS of patients with multiple (station) metastasis of ipsilateral mediastinum and / or submandibular lymph nodes ( HR=0.89, 95% CI: 0.80-0.99). Conclusions:PORT could improve OS and DFS in stage Ⅲ(N 2) NSCLC. A trend towards benefit can be observed in the subgroup with multiple/multi-station N2 metastasis.

Non-small cell lung cancer(NSCLC) is highly malignant and has poor prognosis, in which stage ⅢA(N 2) NSCLC approximately accounts for 20%. Patients with stage ⅢA(N 2) NSCLC have high heterogeneity and distinct survival difference. Loco-regional recurrence and distant metastasis are the main causes of treatment failure. At present, whether stage ⅢA(N 2) NSCLC patients should receive postoperative radiotherapy(PORT) remains controversial. Such patients still lack high level proof to receive PORT.

Objective:To identify the clinical significance of CDK5 in colon cancer tissues.Methods:Two hundred colon cancer tissues were tested for CDK5 expression by immunohistochemistry on tissue microarrays. The correlation between CDK5 expression and clinicopathological features, prognosis and peripheral inflammation-related cells was analyzed.Results:CDK5 was low expressed in 100 cases (50.0%), and high in another 100 cases (50.0%). Longer time to tumor progression ( P=0.026) and overall survival ( P=0.035) were observed in patients with high CDK5 expression. By multivariate analysis , the expression of CDK5 was an independent risk factor for poor prognosis ( HR=0.45,95% CI: 0.21-0.99, P=0.049). The expression of CDK5 was not related to the counts of white blood cells and neutrophils ( P>0.05). Prognosis of patients with a positive lymph node ratio less than 0.15 was significantly better than that of patients with a higher lymph node ratio ( P<0.001). Conclusions:Patients with low CDK5 expression have poor prognosis, and CDK5 expression is not related to the counts of peripheral white blood cells and neutrophils.

Objective:To establish a standard colorectal neoplasm tissue biobank with complete clinical information to provide high quality samples for fundamental and clinical research of colorectal neoplasm.Methods:Based on Affiliated Jinhua Hospital, Zhejiang University School of Medicine, to conduct structural design of colorectal neoplasm tissues, normal tissues and related information. Establish standard operating procedures from the collection and storage of tissue samples, standardize the entry of basic information, medical history, pathology and other relevant clinical information of the patients, and conduct random quality inspections on the pathological morphology and molecular level on a regular basis.Results:A tissue biobank of colorectal neoplasm was successfully constructed. During the establishment and improvement of this tissue biobank, standardized quality control was implemented during the whole-process including sample collection, warehousing, storage and delivery. According to the random sampling quality inspection, the RNA preservation effect was good, the rates of neoplasms in cancer tissue was >80%, and the clinical data of samples were complete.Conclusions:The preliminary construction of colorectal neoplasm tissue biobank not only improves the utilization value of tissue samples, but also provides a guarantee for realizing the bidirectional transformation of fundamental research and clinical application.

PURPOSE: Although it is widely accepted that hormone receptor (HR) status is associated with later post-diagnostic periods, a debate exists as to whether the association is independent of age. The aim of our study was to confirm the impact of HR status on later period breast cancer-specific death (LP-BCSD) and later period non-breast cancer-specific death (LP-non-BCSD) in different age subgroups. METHODS: Surveillance, Epidemiology, and End Results databases were utilized to identify 181,108 breast cancer patients with > 5 years survival. The cumulative incidence of LP-BCSD and LP-non-BCSD was calculated using the Gray method. The subdistribution hazard ratio (SHR) of variables was estimated via the Fine and Gray proportional hazard regression model. Subgroup analyses for LP-BCSD and LP-non-BCSD were performed according to the HR status. RESULTS: The risk of LP-BCSD was exceeded by that of LP-non-BCSD at > 5 years since the diagnosis, particularly in old women. The competing risk regression model indicated that hormone receptor-positive (HR+) was an independent factor for more LP-BCSD (hazard ratio, 1.54; 95% confidence interval, 1.44–1.54; p < 0.001). However, stratified analysis indicated that HR+ was only associated with more LP-BCSD in the young women subgroup. Although HR+ was associated with more LP-non-BCSD, the predictive value of HR+ for LP-non-BCSD was eliminated after adjusting for age. CONCLUSIONS: HR+ was related to LP-BCSD in the premenopausal population. LP-BCSD should be an optimal endpoint in future trials designed to evaluate the role of extended adjuvant endocrine therapy.

Objective To analyze the clinical features, treatment outcomes and prognosis of patients with urinary tract lymphoma. Methods The clinical data of 16 patients in Tongji Hospital of Tongji University from January 2009 to April 2016 were collected and retrospectively analyzed. Results The median age of these patients was 68 years. The onset symptoms of 14 cases were related to urinary system and imaging studies of 10 cases showed masses in the urinary system. The onset regions of lymphoma included:4 cases were renal lymphoma, 5 cases were adrenal lymphoma, 5 cases were testicular lymphoma, 1 case was prostate lymphoma and 1 case was from urethral mouth. The histological type of 12 cases was diffuse large B-cell lymphoma and 10 patients were non-germinal center B cell-like (non-GCB) molecular profiling. Twelve cases belonged to Ann Arbor stages ⅢE- ⅣE, 10 cases had international prognostic index scores ≥3, and 7 cases had B symptoms. 10 patients were confirmed by surgery. Fourteen cases accepted rituximab-containing regimen chemotherapy. Five cases achieved complete response and 3 were partial response. Conclusions The clinical manifestations and imagine examination of patients with urinary tract lymphoma are lack of specificity. The clinical features are highly aggressive and most of the patients are diagnosed at advanced stage. The main histological type is diffuse large B-cell lymphoma and non-GCB molecular profiling. Treatment regimens include surgery combined with chemotherapy and radiotherapy. Earlier diagnosis and treatment may improve the survival of patients.

Objective To investigate the prevalence of nutritional risk and undernutrition of geriatric patients with hip fracture in the department of orthopaedics and analyze the relationship between nutritional risk scores and clinical outcomes.Methods In this prospective cohort study,the baseline demographic data of 235 elderly patients with hip fracture in the department of orthopaedics of Ningbo First Hospital were consecutively recorded from November 2013 to December 2015.The prevalence of nutritional risk and undernutrition,infectious complications,and length of hospital stay were also recorded.The infectious complications and length of hospital stay in patients in different age groups(60-69 years,70-79 years,and ≥80 years)and those with different nutritional risks(<3 points,3-4 points,and ≥5 points)were analyzed.Results All patients without PN EN support during hospitalized durations.The incidence of nutritional risk was 62.98％in 235 elderly patients with hip fracture,twenty patients were undernutritioned by multi-item standard based on Nutritional Risk Screening 2002 nutrition disorder score,and 15 patients were undernutritioned by one-item standard with body mass index.Hip arthroplasty patients had significantly higher nutritional risk than those who had undergone internal fixation(74.04％vs.54.20％,P=0.002).Patients with comorbidities had significantly higher nutritional risk than patients without comorbidities(71.56％vs.55.56％,P=0.011).There were significant differences in infectious complications(2.30％vs.3.91％vs.50.00％)and length of hospital stay[(6.35±0.87)d vs.(8.12±1.13)d vs.(10.85±1.52)d,(8.66±2.06)d vs.(10.45±2.43)d vs.(13.25 ±3.65)d] among patients with different nutritional risks(<3 points,3-4 points,and ≥5 points)(P=0.000).Conclusions Elderly patients with hip fracture has relatatively high nutritional risk.These patients tend to have more complications and longer hospital stay.

Objective To investigate the current situation of the knowledge,attitude and practice of diabetic foot self-care in elderly outpatients with diabetes,and to explore the effective methods of preventing diabetic foot in these population.Methods The study investigated 252 elderly outpatients with diabetes using convenient sampling.Self-designed questionnaires were used to investigate demographics data,and the knowledgeattitude-practice scores of preventing diabetic foot in elderly diabetic patients.The data would been analyzed.Results The average scores of knowledge,attitude and practice of self-care on preventing diabetic foot were respectively (4.74 ± 1.565),(17.69 ± 4.256) and (26.58 ± 4.899).Besides,the scores of the self-protection attitude and the self-protection practice had positive correlation (P ＜ 0.001).Conclusions Elderly outpatients with diabetes have poor knowledge but positive attitude towards self-care of preventing diabetic foot.Moreover,more universal training and education should be conducted,especially for migrant workers,due to their poor behaviors of self-care.

OBJECTIVETo investigate the efficacy and side effects of the consecutive chemotherapeutic protocol, Tongji-96, for adult patients with Philadelphia chromosome negative acute lymphoblastic leukemia (Ph-aALL).

METHODSA retrospective analysis was conducted on 95 cases of Ph-aALL patients treated between January 2004 and December 2012 with Tongji-96 regimen in Tongji hospital, Shanghai.

RESULTSAmong these 95 patients, the overall complete remission (CR) rate was 92.6%, 7-year overall survival (OS) and event-free survival (EFS) rates were (39.3±5.9)% and (31.5±5.3)%, respectively, with the median survival of 28 months. Based on multivariable COX proportional hazards regression model analysis, patients with the poor karyotype and failed to achieve CR after first course induction therapy had a higher risk of mortality compared to those who had good or normal cytogenetics and achieved CR after 1 course of induction treatment [the risk ratios (RR) were 3.380 (95% CI 1.530-7.463, P=0.003) and 3.005 (95% CI 1.522-5.933, P=0.002)，respectively]. By means of Kaplan-Meier analysis and Log-rank test，patients aged less than 60 years and successively achieved CR after first induction therapy had more favorable 7-year OS and EFS rates. Patients with normal karyotype and hyperdiploidy had significantly higher 2-year OS and EFS rates compared with those with complex karyotype, t(4;11) translocation and other karyotypes.

CONCLUSIONAge (60 years as the cut-off)，treatment courses for achieving CR and cytogenetics were predictive factors for the prognosis of Ph-aALL from this retrospective study. As a comprehensive and sequential therapy protocol, Tongji-96 regimen was proved to obtain long-term survival, reduce risks for relapse and improve outcomes for part Ph-aALL patients.

Objective To assess the clinical value of transcatheter arterial chemoembolization (TACE) together with radiofrequency ablation (RFA) and sorafenib in treating recurrent hepatocellular carcinoma (HCC) after surgery.Methods A total of 40 patients with recurrent HCC after surgery, who were encountered at authors' hospital during the period from December 2009 to May 2014, were collected. The patients were divided into the study group (n=20) receiving TACE combined with RFA and sorafenib and the control group (n=20) receiving TACE plus RFA. Within 7-10 days after TACE, RFA was carried out. In the study group, oral sorafenib therapy (400 mg, two times everyday) started at 4 days after TACE. Withdrawal of sorafenib would be ordered if drug resistance occurred. Each patient underwent TACE combined with RFA not less than two times. Results The median survival time of the study group and the control group was 31.0 months and 24.8 months respectively, and statistically significant difference existed between the two groups (P<0.05). The one-year, 2-year and 3-year survival rates of the study group were 85%, 70% and 50%respectively, while the one-year, 2-year and 3-year survival rates of the control group were 80%, 55% and 30% respectively; the differences between the two groups were not statistically significant (P>0.05). The progression free survival (PFS) time of the study group and the control group was 6.8 months and 5.7 months respectively, the difference between the two groups was statistically significant (P<0.05). Conclusion TACE combined with RFA and sorafenib can prolong the overall survival time and the progression free survival time of patients with recurrent HCC after surgery.
