Method: A systematic review of the English language literature between 1990 and 2013 was conducted to identify studies relevant to the objective. Searches were carried out on the database PubMed, by using the title term “male breast cancer”. Results: The majority of male patients present with a painless, firm, subareolar lump. Experience of male breast imaging is good but limited. However, there is no definitive therapeutic algorithm. Men are often treated with mastectomy instead of breast conserving surgery and mostly tamoxifen is used as an adjuvant therapy. The most important prognostic factors are tumor size and lymph node status in the armpit. Conclusion: More increased awareness and further research are needed to improve the diagnosis and treatment of this disease.展开更多

Methods: 34 patients with male breast cancer were retrospectively analyzed, who were diagnosed and treated in the First Hospital of Jilin University between 1980 and March 2005. Results: Clinical TNM stage of the patients were stage Ⅰ, 6 patients, stage Ⅱ, 24 patients and stage Ⅲ, 4 patients'. Positive lymph nodes were found in 35.3% of the patients. All these patients received modified radical mastectomy. The 5-year survival rate was 65.3%. Postoperation recurrence rate was 11.8%. Conclusions: Patients with male breast cancer should receive surgical treatment, assisted with adjuvant treatment, such as radiotherapy, chemotherapy, endocrine therapy and so on. TNM stage and expression of hormone receptor may be the main factors affecting the prognosis.展开更多

The Barcelona Clinic Liver Cancer(BCLC) classification has been endorsed as the optimal staging system and treatment algorithm for HCC by the European Association for the Study of Liver Disease and the American Association for the Study of Liver Disease. However, in real life, the majority of patients who are not considered ideal candidates based on the BCLC guideline still were performed hepatic resection nowadays, which means many hepatic surgeons all around the world do not follow the BCLC guidelines. The accuracy and application of the BCLC classification has constantly been challenged by many clinicians. From the surgeons' perspectives, we herein put forward some comments on the BCLC classification concerning subjectivity of the assessment criteria, comprehensiveness of the staging definition and accuracy of the therapeutic recommendations. We hope to further discuss with peers and colleagues with the aim to make the BCLC classification more applicable to clinical practice in the future.展开更多

The aim of this study was to compare the prognosis of MBC and FBC patients in China and the prognosis of MBC and their corresponding postmenopausal FBC patients.Methods Thirty-five MBC patients who were treated at the Sun Yat-sen University Cancer Center between 1969 and 2004 were enrolled in the study. Seventy FBC patients who were matched with the MBC patients for TNM stage, year of diagnosis, and age at diagnosis were simultaneously enrolled in the study. A second group comprising 18 MBC patients and their corresponding 36 matched postmenopausal FBC patients were also enrolled. The whole group and the postmenopausal groups were compared for five- and ten-year survivals. Results All the factors that could potentially affect prognosis were comparable among the groups except more FBC than MBC patients underwent endocrine therapy and a modified radical mastectomy. The 5- and 10-year survivals in the whole group were 81.6% and 60.3% for men and 90.7% and 73.5% for women (P=0.02). The 5- and 10-year survival in the postmenopausal group was 82.5% and 100% for men and 66.0% and 85.9% for women (P=0.159).Conclusions Chinese FBC patients had a better prognosis than Chinese MBC patients. However, MBC patients and their corresponding postmenopausal FBC patients had a similar prognosis.展开更多
