Article: [Efficacy of modified radical operation of preserving nipple-areolar complex on early stage breast cancer].[show abstract] [hide abstract]
ABSTRACT: Modified radical mastectomy of preserving nipple-areolar complex (NAC) is an important surgical therapy for stage I-IIa breast cancer, but the oncological risk is controversial. This study was to compare the efficacy of NAC-preserving modified radical operation and conventional modified radical operation on early stage breast cancer. The patients who received NAC-preserving modified radical operation (42 patients) or conventional modified radical operation (84 patients) from January 1998 to December 2003 in the First Affiliated Hospital of Bengbu Medical College were matched with a ratio of 1:2 by age at diagnosis, axillary lymph node status, sexual hormone receptor status, tumor size and Her-2/neu expression for retrospective analysis. The loco-regional recurrence, distant metastasis, 5-year disease-free survival (DFS) and 5-year overall survival (OS) between the two groups were compared. Median follow-up time was 48 months in NAC-preserving operation group and 44 months in conventional operation group. The 5-year occurrence rate of loco-regional recurrence was 2.44% in NAC-preserving operation group and 3.21% in conventional operation group (P=0.771). The 5-year occurrence rate of distant metastasis was 5.64% in NAC-preserving operation group and 4.30% in conventional operation group (P=0.654). The 5-year OS rates were 96.00% in NAC-preserving operation group and 98.18% in conventional operation group (P=0.694). The 5-year DFS rates were 91.67% in NAC-preserving operation group and 92.26% in conventional operation group (P=0.597). Modified NAC-preserving radical operation results in the same effect on early stage breast cancer as conventional modified radical operation based on careful consideration of the indications, and results in better cosmetic appearance after restitution and better quality of life.Ai zheng = Aizheng = Chinese journal of cancer 05/2009; 28(4):408-11.
Article: [Clinicopathologic analysis of the nipple-areolar complex occult involvement in early stage breast carcinoma].[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to investigate the incidence of nipple-areola complex (NAG) involvement in stage I - II a breast cancer patients who underwent skin-sparing mastectomy and to determine the associated risk factors, to provide a theoretical basis for modified radical mastectomy preserving NAC and breast reconstruction in early stage breast cancer patients. A total of 68 women with primary breast cancer were included in this study. The following associated risk factors of NAC involvement were assessed and compared with those of non-involvement: the distance from the tumor site to the edge of areola (D), axillary lymph node status, over-expression of HER-2/neu, location of tumor, TNM stage, abnormal nipple (nipple indentation, erosion, discharge), tumor size, age, histological type, as well as status of estrogen receptor (ER) and progesterone receptor (PR), by Chi-square test. The positive rate of NAG involvement was 13.2%. It decreased with an increase in the distance from the tumor site to the edge of the areola (D) (chi2 = 10.68, P <0.01)), and higher incidence of NAG involvement was found in patients with axillary lymph node metastasis (chi2 = 14. 61, P < 0.01) and over-expression of HER-2/neu (chi2 =6.83, P <0.01). Location of tumor (P <0.01), TNM stage (chi2 =3.85, P <0.05), abnormal nipple (chi2 = 11.65, P<0.01), and tumor size (chi2 =4.13, P <0.05) also had influence on the NAG involvement. No significant correlation between NAC involvement and age (P > 0.05)), histological type (chi2 = 0.07, P > 0.05)), as well as status of estrogen receptor (ER) (chi2 = 0.06, P > 0.05) and progesterone receptor (PR) (chi2 = 0.04, P > 0.05) was found. Most of the NAG involvement was caused by ductal infiltration. In the stage I - II a breast cancer patients, location of tumor, TNM stage, the distance from the tumor site to the edge of areola (D), abnormal nipple, over-expression of HER-2 and metastases in axillary lymph nodes are the primary influential factors of NAG involvement.Zhonghua zhong liu za zhi [Chinese journal of oncology] 04/2008; 30(3):203-6.
