目的 初步探讨影响男性乳腺癌患者预后的因素。 方法 收集2003年1月－2011年12月经病理确诊、接受治疗、临床资料较完整的36例男性乳腺癌患者的临床资料。采用对数秩检验和Cox回归分析影响男性乳腺癌患者预后的因素。 结果 36例患者无进展生存期（PFS）为3～95个月，中位PFS为45个月。单因素分析显示：肿瘤直径（P=0.001）、阳性淋巴结（P=0.001）、TNM分期（P＜0.001）、手术方式（P=0.001）是影响预后的因素。多因素分析显示：阳性淋巴结（P=0.024）和TNM分期（P=0.022）是影响预后的主要因素。 结论 阳性淋巴结和TNM分期是影响预后的主要因素，以手术为主的综合治疗模式是提高男性乳腺癌患者生存率的重要措施。
Objective To discuss the clinicopathologic risk factors related to local recurrence of rectal cancer after radical surgery. Methods The complete clinicopathologic data of 368 patients with rectal cancer from January 2004 to April 2011 in this hospital were retrospectively analyzed by univariate and multivariate analysis methods. Results There were 73 cases suffered from local recurrence and accounted for 19.84% （73/368） of rectal cancer during the same period. Univariate analysis results showed that gender， tumor from anal margin， tumor circumference， TNM staging， histology type， vessel infiltration， tumor perforation， stomal leak， and chemoradiotherapy were associated with postoperative recurrence （P＜0.05）. Multivariate analysis results showed that tumor from anal margin， tumor circumference， TNM staging， histology type， vessel infiltration， tumor perforation， and chemoradiotherapy were prognostic factor for local recurrence of rectal cancer （P＜0.05）. Conclusions There are many factors related to postoperative local recurrence， but the most dangerous factor is vessel infiltration.
ObjectiveTo investigate the prognostic factors for inflammatory breast cancer based on the data from West China Hospital with a relatively large sample. MethodsClinical data of 41 patients with histopathologically confirmed inflammatory breast cancer (IBC) who received treatment at West China Hospital Oncology Center of Sichuan University between January 2009 and December 2014 were collected and analyzed. Log-rank test and Cox regression model were used for statistical analysis. ResultsIn the study, negative estrogen receptor, negative progestrone receptor and positive human epidermal growth factor receptor-2 were identified in 58.5%, 61.0% and 34.2% of the inflammatory breast cancer tissues, respectively. Progress free survival (PFS) were between 2 and 60 months, with a median of 35 months. Univariate analysis showed that Tumor Node Metastasis (TNM) stage (P=0.016) and therapeutic effect (P=0.002) influenced the survival. Multivariate analysis showed that TNM stage (P=0.006), therapeutic effect (P=0.002), and anthracycline-taxane based chemotherapy (P=0.041) were the significant prognostic factors. ConclusionTNM stage is the major prognostic factor for IBC. Preoperative chemotherapy with paclitaxel-epirubicin combination can improve the PFS of IBC. Comprehensive treatment mode with operation is recommended for the treatment of IBC.
ObjectiveBy analyzing the correlation between the clinicopathological features of patients with colorectal liver metastases (CRLM) and their postoperative survival, this study is aimed to identify new and accurate prognostic indicators on the prognoses to provide a reference of the treatment strategy selection for patients with CRLM. MethodsThe clinical data of 233 patients with CRLM who received operation treatments in the Eastern Hepatobiliary Hospital of the Second Military Medical University from January 2006 to December 2009 were retrospectively investigated, and their clinicopathological features, as well as their prognosis were analyzed. The survival curve was drawn by Kaplan-Meier method, and the survival rates were analyzed by log-rank test. Parametric survival analysis was used to identify predictors of cancer-specific survival. ResultsThe median survival time after cancer resection was 37.0 months, with cumulative 1-year, 3-year, and 5-year survival rates of 93.0%, 61.0%, and 17.0%, respectively. The median survival time, with cumulative 3-year, and 5-year survival rates of patients who had received radical operations was better than the others who received palliative operations:40.53 months vs 27.20 months, 59.0% vs 29.0%, and 20.0% vs 0(P < 0.05), respectively. In overall surviva, the results of univariate analysis showed that 13 factors, including surgical method, the first relapse after liver metastasis resection, the number of liver metastases, surgical margin, other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, whether any chronic liver disease was associ-ated, preoperative serum CEA level, preoperative serum CA19-9 leve, the position of the liver metastases, whether the liver metastasis capsule was complete, TNM stagethe of primary cancer, whether the liver metastasis was simultaneous liver metastases, and the maximum diameter of the liver metastases, were closely related to the clinicopathological features associated with prognosis and the differences were statistically significant (P < 0.05). The results of multivariate survival analysis demonstrated that received palliative operations, simultaneous liver metastases, there were other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, liver metastases without a complete capsule, the number of liver metastases appeared as multiple and widedistribution, unassociated chronic liver disease of the patients, the maximum diameter of the liver metastases>3 cm, were the independent risk factors affecting the postoperative survival of the patients with CRLM (P < 0.05). ConclusionsIt is important for long-term survival of patients with CRLM who were received operations. Received palliative operations, simultaneous liver metastases, there were other unresectable extrahepatic metastases or resectable invasion in blood vessels or the surrounding tissue, liver metastases without a complete capsule, the number of liver metastases appeared as multiple and widedistribution, unassociated chronic liver disease of the patients, the maximum diameter of the liver metastases>3 cm, were the independent risk factors affecting the postoperative survival of the patients with CRLM.
