After adjuvant chemotherapy, autologous CIK cells were introduced in 147 cases(CIK group), while adjuvant chemotherapy alone was used to treat the remaining 147 cases(control group). The major endpoints of the investigation were the disease-free survival(DFS) and overall survival(OS). Additionally, the side effects of the treatment were evaluated.Results: In the CIK group, the DFS and OS intervals of the patients were significantly longer than those of the control group(DFS:P = 0.047;OS: P = 0.007). The multivariate analysis demonstrated that the TNM(tumor-node-metastasis) stage and adjuvant CIK treatment were independent prognostic factors for both DFS [hazard ratio(HR)= 0.520, 95% confidence interval(CI):0.271-0.998, P = 0.049;HR = 1.449, 95% CI:1.118-1.877, P = 0.005, respectively] and OS(HR=0.414, 95% CI:0.190-0.903, P = 0.027;HR= 1.581, 95% CI:1.204-2.077, P = 0.001, respectively) in patients with TNBC. Additionally, longer DFS and OS intervals were associated with increased number of CIK treatment cycles(DFS: P = 0.020;OS: P = 0.040). The majority of the patients who benefitted from CIK cell therapy were relatively early-stage TNBC patients.Conclusion: Chemotherapy in combination with adjuvant CIK could be used to lower the relapse and metastasis rate, thus effectively extending the survival time of TNBC patients, especially those at early stages.展开更多

In this study, we performed a retrospective analysis using clinical and pathologic data from 109 nonmetastatic operable male breast cancer patients treated from January 1996 to December 2011 at Tianjin Medical University Cancer Institute and Hospital. Log-rank test showed that lower tumor stage, no lymph node involvement, and positive estrogen/progesterone receptor status were good predictors of both disease-free survival and overall survival on univariate analysis. However, hormonotherapy is only a good predictive factor of disease-free survival, and not of overall survival. In addition, based on a Cox proportional hazard regression model, only lymph node involvement, and estrogen/progesterone receptor status were statistically significant predictive factors on multivariate analysis. Our results demonstrated that although adjuvant systemic therapy is used extensively in male breast cancer patients and prognosis has improved over the last few decades, lymph node involvement, and estrogen/progesterone receptor status are still the most important prognostic factors. A prospective multi-center study with a larger sample size is urgently needed to further understand male breast cancer.展开更多
