“…Since its establishment in 1977, nearly all new breast cancer patients have been registered in the DBCG database. 19 The DBCG has prepared national guidelines for diagnostic and therapeutic procedures in patients with primary invasive breast cancer, which were later supplemented by guidelines for in situ carcinomas and hereditary breast cancer. 19 The information on the breast cancers includes date of primary surgery, tumor size (in mm), number of tumor-positive lymph nodes, estrogen and progesterone receptor status, chemotherapy and/or hormone therapy, radiotherapy, and date of disease recurrence and/or death.…”

BACKGROUND: A few small studies published to date have suggested that major psychosocial problems develop in the partners of cancer patients; however, to the authors' knowledge, no studies to date have addressed their risk for severe depression. In a retrospective cohort study, the risk for hospitalization with an affective disorder of the male partners of women with breast cancer was investigated, using unbiased, nationwide, population-based information. METHODS: Followed were 1,162,596 men born between 1925 and 1973 who were aged 30 years at study entry, resided in Denmark between 1994 and 2006, had no history of hospitalization for an affective disorder, and had lived continuously with the same partner for at least 5 years. A Cox regression analysis included detailed clinical information regarding the diagnosis and treatment of breast cancer and on annually updated socioeconomic and healthrelated indicators obtained from national administrative and disease registers. RESULTS: During the 13 years of follow-up, breast cancer was diagnosed in the partners of 20,538 men. On multivariable analysis, men whose partner was diagnosed with breast cancer were found to be at an increased risk of being hospitalized with an affective disorder (hazards ratio, 1.39; 95%confidence interval, 1.20-1.61), with a dose-response pattern for the severity of breast cancer. Furthermore, men whose partner died after breast cancer had a significant, 3.6-fold increase in risk for an affective disorder when compared with men whose partner survived breast cancer. CONCLUSIONS: The results of the current study supported the hypothesis that men whose partner had breast cancer were at an increased risk for hospitalization with an affective disorder.

“…Because information on radiotherapy is not kept by the Swedish Register, hospital records were used to determine which women had received radiotherapy. In Denmark, all women for whom data were recorded in the register held by the Danish Breast Cancer Cooperative Group 16 were considered for the study if they received the diagnosis of breast cancer between 1977 and 2000, were younger than 75 years at the time of diagnosis, and received radiotherapy. The study was approved by the Danish Data Protection Agency and by the ethics review board of the Karolinska Institutet in Stockholm.…”

Background: The continuous improvements in diagnosing and treatment of breast cancer are reflected in the ever changing pattern of recurrence. The aim of the study was to investigating recurrence pattern and prognostic factors of recurrence in a population-based cohort. Results: Median follow-up was 5.3 years (range 0.3-14.4). In total 183 women experienced breast cancer recurrence, 44 ipsilateral breast cancer recurrence, 13 regional recurrences, and 126 distant metastasis (DM). This corresponds to a cumulative risk of DM as first event at five and nine years of 6.5% and 12.6%, respectively. Further 42 women developed breast cancer in the contralateral breast. Disease-free survival (DFS) at five and nine years was 88% and 76%, respectively. Large tumor size (>20 mm), lymph node involvement, and vascular invasion were significantly associated with increased risk of DM. Margin width and age were not associated with risk of DM. Conclusion: Acceptable recurrence rates and DFS were observed. Patients with large tumors, lymph node involvement, and vascular invasion had an increased risk of DM.
