Objective To explore the characters and therapy of the triple-negative breast cancer （TNBC）. Methods The pertinent literatures with key words “triple-negative breast cancer”，“diagnosis”，and “therapy” were retrieved and reviewed. Results TNBC was a subtype of breast cancer characterized by negative expressions of estrogen receptor （ER），progesterone receptor （PR），and human epidermal growth factor receptor-2 （HER-2）. The clinicopathologic feature and prognosis of TNBC were distinct from other breast cancer. The age of onset was younger，disease free survival and total survival rate were lower in the patients with TNBC. At present， the therapy guideline was lack of TNBC，which referred to the non-TNBC，including local surgery，systemic chemotherapy，and the target therapy was at the clinical trial stage. Conclusions TNBC is one of heterogeneity characteristics for the breast cancer，which has extra much difference. For improving the TNBC prognosis，we hope that more and more significant markers to TNBC in the future are found，which are useful to make individuation treatment.
Objective To evaluate the feasibility, oncological safety, and aesthetic result of skin-spring mastectomy (SSM) or nipple-spring mastectomy (NSM) in breast reconstruction of implant (permanent gel or expander) for breast cancer patients who were not fit for the breast conserving surgery (BCS). Methods Between October 2005 and July 2011, 89 women with breast caner underwent SSM or NSM, with an average age of 42.4 years (range, 19-55 years) and an average disease duration of 5.7 months (range, 1-24 months). The pathological examination revealed invasive ductal carcinoma in 55 cases, ductal carcinoma in situ (DCIS) in 15 cases, invasive ductal carcinoma + DCIS in 8 cases, DCIS with infiltration in 10 cases, and occult breast cancer in 1 case. According to tumor staging criterion of American Joint Committee on Cancer (AJCC), 15 cases were rated as stage 0, 51 cases as stage I, 22 cases as stage II, and 1 case as unclear. Finally, 33 patients underwent SSM and 56 patients underwent NSM according to the location and diameter of tumor and the infiltration of tumor to nipple. Secondary breast reconstruction was performed with permanent gel replacement after axillary lymph node dissection in 9 patients with positive sentinel lymph node and 1 patient with occult breast cancer; immediate breast reconstruction was performed with permanent gel in the other patients. All the patients received the chemotherapy or/and radiotherapy according to the National Comprehensive Cancer Network (NCCN) guideline. Results Complications occurred in 5 patients undergoing breast reconstruction of permanent gel after NSM, including 1 case of haemorrhage, 2 cases of infection, and 2 cases of local skin necrosis. Primary healing of incision was obtained in the others. No nipple necrosis was observed in patients undergoing NSM. All the patients were followed up 14-88 months (median, 40 months). At 10 months after operation, the aesthetic results were excellent in 40 cases, good in 33 cases, fair in 14 cases, and poor in 2 cases, with an excellent and good rate of 82%. No recurrence or metastasis was found during follow-up. Conclusion The SSM or NSM is feasible and oncological safe for patients who are not fit for BCS, with satisfactory aesthetic result.
目的探讨甲状腺功能亢进（简称甲亢）手术后出现骨饥饿综合征的发病机理。方法回顾性分析四川大学华西医院2009年收治的2例甲亢手术后严重低钙患者的临床资料。结果本组2例病例在甲亢手术后均出现了严重低钙血症，1例低镁血症; 2例病例手术前、后骨代谢碱性磷酸酶均有不同程度升高。结论甲亢手术后骨饥饿综合征是多因素造成的临床症状，所以对手术后低钙症状应给予正确分析和判断，并尽可能在问题出现前给予预测和处理。对于甲亢患者和绝经期女性在围手术期给予钙的补充，手术中注意保存甲状旁腺血供是减少骨饥饿综合征的最佳手段，甲亢手术后及时补钙是必要的。
Objective To investigate the relationship between skin/pectoral muscle invasion and the prognosis of male breast cancer. Methods Clinical data and follow-up information of 79 male breast cancer patients who received treatment between September 2008 to April 2020 in West China Hospital were retrospectively reviewed, to analyze the clinicopathological features of male breast cancer and prognostic value of skin/pectoral muscle invasion. Results Among 79 male breast cancer patients, a total of 23 patients (29.1%) were with skin/pectoral muscle invasion at diagnosis. All the patients were followed up, with a median follow-up period of 63.3 months (1.0–204.5 months). Within follow-up period, 8 patients (10.1%) suffered from relapse, 19 patients (24.7%, 19/77) suffered from metastasis, and 4 patients (5.1%) died. Multivariate Cox proportional risk regression model suggested that patients with skin/pectoral muscle invaded had poor disease free survival [RR=4.48, 95%CI (1.08, 18.52), P=0.038]. Conclusions Skinor pectoral muscle invasion might be a valuable prognostic factor for male breast cancer patients. However, limited by sample size, the conclusion should be proved by further high-level studies.
