[Objective] To evaluate the effectiveness and the cosmetic result of radiotherapy after breast conserving surgery for early breast cancer. [Methods] A total of 97 early invasive breast carcinoma in women who had undergone previous breast-conserving surgery were treated with postoperative irradiation. [Results] The median follow-up time was 60 months, the overall survival rate was 97.3% and the locoregional recurrence rate was 3.21%, as calculated using the Kaplan-Meier method. Excellent and good cosmetic result was noted in 91 patients. [Conclusion] Breast-conserving therapy, consisting of breast-conserving surgery followed by breast radiotherapy, has therefore become the standard regimen for treatment of early invasive breast cancer.

Numerous studies have investigated the risk of colorectal cancer (CRC) associated with the polymorphism of DNA methyltransferase 3B (DNMT3B) 149 C>T, but results have been inconsistent. We performed this meta-analysis to drive a more precise estimation of the association between this polymorphism and risk of CRC. A comprehensive search was conducted to identify all case-control studies of the -149C>T polymorphism of DNMT3B and CRC risk. A total of seven eligible studies, including 2,666 cases and 4,022 controls, relating the DNMT3B polymorphism of -149C>T to the risk of CRC were identified. It suggested no significant associations between -149C>T polymorphism of DNMT3B gene and the risk of developing CRC in the recessive, dominant, and co-dominant models (for CC versus TT: OR = 0.90, 95 % CI = 0.90-1.25, P heterogeneity = 0.37; for recessive model: OR = 0.54, 95 % CI = 0.28-1.04, P heterogeneity = 0.00001; for dominant model: OR = 1.07, 95% CI = 0.93-1.23, P heterogeneity = 0.83; and for C allele versus T allele: OR = 0.70, 95 % CI = 0.43-1.13, P heterogeneity = 0.00001). In the subgroup analysis, there is no significant associations were also found in European populations (for CC versus TT: OR = 1.09, 95 % CI = 0.92-1.30, P heterogeneity = 0.88; for recessive model: OR = 1.00, 95 % CI = 0.88-1.13, P heterogeneity = 0.14; for dominant model: OR = 1.50, 95 % CI = 0.89-2.54, P heterogeneity = 0.00001; and for C allele versus T allele: OR = 0.70, 95 % CI = 0.38-1.28, P heterogeneity = 0.00001). In conclusion, no significant association was found between the -149C>T polymorphisms in DNMT3B and CRC susceptibility. © 2013 International Society of Oncology and BioMarkers (ISOBM). Source
