Objective To summarize the role of N-myc downstream regulated gene 1 (NDRG1) and the advancement of it in tumor research. Methods Publications on line at home and abroad involving the roles of NDRG1 and the correlation between it and tumor were collected and reviewed. Results NDRG-1, has a number of important functions such as in organism responses in hypoxia, histological differentiation, and so on, especially plays a significant role in generation, metastasis, and invasion of cancer. Conclusion NDRG1 may be a candidate of metastasis relevant gene for cancer and may serve as a useful prognostic marker of carcinoma.
ObjectiveTo evaluate the prognostic significance of metastatic lymph nodes ratio (MLNR) in patients with node-positive breast cancer. MethodsThe clinical data of 94 patients with nodepositive breast cancer underwent modified radical mastectomy were retrospectively analyzed. The survival rate and prognosis factors of patients with complete follow-up data were assessed by log-rank test and multivariate regression analysis. Results The survival time of 94 patients ranged from 12-75 months, with median 64 months. The 5-year overall survival rate was 72.34% (68/94). The total MLNR was 0.31 (486/1 553). Univariate analysis demonstrated that the survival was influenced significantly by tumor size, number of lymph node metastasis, MLNR, ER status, and radiotherapy or not (Plt;0.05), but not by patient’s age, menopause or not, PR status, endocrine therapy or not, and histological type (Pgt;0.05). Multivariate analysis showed that MLNR (OR=2.565, 95%CI=1.043-6.309， P=0.040) and tumor size (OR=2.220, 95%CI=1.045-4.716， P=0.038) were independent prognostic factors for the patients with node-positive breast cancer. Conclusion MLNR is a major independent prognostic factor for the patients with node-positive breast cancer, which is more accurate than the number of metastatic lymph nodes in predicting the survival of patients with node-positive breast cancer.
目的 探讨皮肌炎合并乳腺恶性肿瘤的临床特征、诊治及预后情况。方法 回顾性分析我科自2008年以来收治的3例皮肌炎合并乳腺恶性肿瘤患者的临床资料,就两者关系结合文献进行分析。结果 3例皮肌炎合并乳腺恶性肿瘤患者中2例行乳腺癌改良根治术,病理报告为浸润性导管癌(淋巴结14/21枚转移)和原位癌(淋巴结0/17枚转移,伴4枚癌结节),因术后不能耐受静脉化疗,予内分泌治疗。1例行乳房肿瘤切除术及腋窝淋巴结活检术,2个月后因肺间质病死亡。结论 女性皮肌炎患者易伴发乳腺恶性肿瘤且预后差,对明确诊断为皮肌炎的女性患者有必要进行乳腺恶性肿瘤的筛选。
