Objective:To investigate the prognostic factors of patients with pancreatic body and tail carcinoma.Methods:The clinical data of 64 patients with pancreatic body and tail carcinoma who underwent surgical resection or endoscopic ultrasound biopsy and were pathologically confirmed in the Second Affiliated Hospital of Jiaxing University from January 2013 to March 2020 were retrospectively analyzed. Age, gender, diabetes mellitus, serum CEA and CA19-9 levels at initial diagnosis, tumor site, maximum tumor diameter, TNM stage and treatment method were collected. Kaplan-Meier method was used to draw survival curve, and Log-rank test was used to analyze survival rate. Univariate and multivariate Cox proportional risk regression models were used for prognostic analysis.Results:Among the 64 patients, 24 patients were complicated with diabetes; serum CEA level was increased in 36 cases, and serum CA19-9 level was increased in 46 cases; 8 cases were in TNM stage ⅠA, 4 cases were in ⅠB stage, 4 cases were ⅡA stage, 4 cases were in ⅡB stage, 8 cases were in Ⅲ stage, and 36 cases were in Ⅳ stage. Symptomatic treatment was performed in 18 cases, chemotherapy combined with immunotherapy were in 18 cases, and surgical comprehensive therapy (surgery combined with chemotherapy and immunotherapy) were in 26 cases. Univariate analysis showed that diabetes mellitus, serum CEA and CA19-9 levels, TNM stage and treatment mode were related factors affecting the prognosis of patients with pancreatic body and tail carcinoma (all P value <0.05). Multivariate analysis indicated that TNM stage ( HR=2.536) and surgical comprehensive therapy ( HR=0.285) were the independent factors affecting the prognosis of patients with pancreatic body and tail carcinoma ( P<0.05). Median survival was 25 months (95% CI 21.416-28.584) for patients with TNM stage Ⅲ+ Ⅳ pancreatic body and tail carcinoma treated with surgical comprehensive therapy, 11 months (95% CI 7.246-14.754) for patients treated with chemotherapy combined with immunotherapy, and 6 months (95% CI 3.819-8.181) for patients treated with symptomatic treatment; the median survival time of patients with surgical comprehensive therapy was significantly longer than that of patients with chemotherapy combined with immunotherapy and symptomatic treatment, and the difference was statistically significant ( P<0.05). Conclusions:TNM stage and surgical comprehensive therapy were the prognostic factors affecting the prognosis of patients with pancreatic body and tail carcinoma, and surgical comprehensive therapy may be the best choice for long-term survival of patients.

Chest trauma is one of the most common injuries. Venous thromboembolism (VTE) as a common complication of chest trauma seriously affects the quality of patients′ life and even leads to death. Although there are some consensus and guidelines on the prevention and treatment of VTE at home and abroad, the current literatures lack specificity considering the diagnosis, treatment and prevention of VTE in patients with chest trauma have their own characteristics, especially for those with blunt trauma. Accordingly, China Chest Injury Research Society and editorial board of Chinese Journal of Traumatology organized relevant domestic experts to jointly formulate the Chinese expert consensus on the diagnosis, treatment and prevention of chest trauma venous thromboembolism associated with chest trauma (2022 version). This consensus provides expert recommendations of different levels as academic guidance in terms of the characteristics, clinical manifestations, risk assessment, diagnosis, treatment, and prevention of chest trauma-related VTE, so as to offer a reference for clinical application.

"The Expert Group on Tumor Ablation Therapy of Chinese Medical Doctor Association, The Tumor Ablation Committee of Chinese College of Interventionalists, The Society of Tumor Ablation Therapy of Chinese Anti-Cancer Association and The Ablation Expert Committee of the Chinese Society of Clinical Oncology" have organized multidisciplinary experts to formulate the consensus for thermal ablation of pulmonary subsolid nodules or ground-glass nodule (GGN). The expert consensus reviews current literatures and provides clinical practices for thermal ablation of GGN. The main contents include: (1) clinical evaluation of GGN, (2) procedures, indications, contraindications, outcomes evaluation and related complications of thermal ablation for GGN and (3) future development directions.
