Background: This study investigated the differences in clinicopathologic features and surgical treatment between an Italian and a Chinese cohort of premenopausal women with breast cancer, and highlighted the potential advantages of international medical exchange projects. Methods: Premenopausal women who underwent surgical treatment between 2012 and 2016 at one Italian and one Chinese institution participating in a medical exchange program were compared. Factors associated with the probability to receive mastectomy were determined via logistic analysis. Changes in surgical management at the Chinese institution in the period 2018–2019, after the exchange program, were also evaluated. Results: A total of 505 patients, 318 from Italy and 187 from China, were evaluated. The Chinese patients had more frequently advanced-stage tumours, large tumour size (30.9 vs. 18.1 mm, p < 0.01), invasive carcinoma (92.5 vs. 83.3%, p < 0.01), positive axillary lymph nodes (54.5 vs. 27.4%, p < 0.01), Her-2 positivity (36.4 vs. 22.0%, p < 0.01), and high proliferative index (55.1 vs. 30.2%, p < 0.01). Positive oestrogen receptor status and rates of triple-negative breast cancer did not differ (77.0 vs. 69.5%, p = 0.09 and 14.2 vs. 16%, p = 0.56, respectively). Mastectomy rates were higher among Chinese women (85 vs. 41%, p < 0.001), whereas use of sentinel node biopsy was more frequent among Italian women (77 vs. 33%, p < 0.001). Chinese women had more than 4-fold higher risk of receiving mastectomy. In the last 2 years, the rates of breast-conserving surgery and sentinel node biopsy at the Chinese institution increased from 15 to 23%, and from 33 to 42%, respectively. Conclusions: Tumour features and surgical strategies for premenopausal breast cancer may differ significantly between Italy and China. Since the international exchange program, patients from the Chinese institution have been offered more frequently less invasive surgery. International exchange programs can help in designing epidemiological studies which may be useful for strategies to improve breast cancer management and control.

Complete Lymph Node Dissection

SummaryThe international consensus conference from St. Gallen concerning the treatment of early breast cancer concluded in 2003, that sentinel node biopsy was now accepted as method allowing axillary staging in breast cancer. This procedure may avoid complete lymph node dissection in appropriate cases. Since numerous questions associated with the technique are still not defined and the procedure itself is not yet standardized, the German Society of Senology defined the conditions for the routine clinical use of sentinel node biopsy in an interdisciplinary consensus meeting.

ABSTRACT Objective: To determine if specific dietary patterns are associated with breast cancer risk in Chinese women. Design: Latent class analysis (LCA) was performed to identify generic dietary patterns based on daily food-frequency data. Setting: The Chinese Wuxi Exposure and Breast Cancer Study (2013-2014). Participants: A population-based case-control study (695 cases, 804 controls). Results: Four dietary patterns were identified, Prudent, Chinese traditional, Western, and Picky, the proportion in the controls and cases were 0.30/0.32/0.16/0.23 and 0.29/0.26/0.11/0.33, respectively. Women in Picky class were characterized by higher extreme probabilities of non-consumption on specific foods, the highest probabilities of consumption of pickled foods, and the lowest probabilities of consumption of cereals, soy foods, and nuts. Compared with Prudent class, Picky class was associated with a higher risk (OR=1.42, 95%CI=1.06, 1.90), while the relevant association was only in post- (OR=1.44, 95%CI=1.01, 2.05) but not premenopausal women. The Western class characterized by high-protein, -fat, and -sugar foods, the Chinese traditional class characterized by typical consumption of soy foods and white meat over red meat, both of them showed no difference in BC risk compared with Prudent class did. Conclusions: LCA capture the heterogeneity of individuals embedded in the population, could be a useful approach in the study of dietary pattern and disease. Our results indicated that the Picky class might have a positive association with the risk of breast cancer.
