TLDR
Analysis of survival curves of women with breast cancer suggests that two or more populations exist, with about 40% suffering fatal outcome unaffected by treatment, and the remaining 60% exhibit a relative mortality only modestly different from that of women of similar ages without evidence of disease.Abstract:
Randomized trials comparing surgical treatments of breast cancer show that radical mastectomy offers no greater benefit than simple mastectomy followed by radiotherapy. Furthermore, in terms of survival, radical mastectomy seems to be no better than wide excision followed by radiotherapy when the disease is clinically diagnosed as stage 1. The incidence of diagnosed breast cancer showed an 18% increase between 1935 and 1965 and a 50% increase between 1965 and 1975. However, breast cancer mortality has remained unchanged for at least the past 40 years. Analysis of survival curves of women with breast cancer suggests that two or more populations exist, with about 40% suffering fatal outcome unaffected by treatment. The remaining 60% exhibit a relative mortality only modestly different from that of women of similar ages without evidence of disease. Increasing detection of an entity that is histologically defined as malignant but biologically relatively benign could account for the observed increase in incidence. (JAMA241:489-494, 1979)read more

TL;DR: The results strongly support the idea that many of these breast tumor subtypes represent biologically distinct disease entities.

Screening for breast cancer with mammography.
TL;DR: It is found that breast cancer mortality was an unreliable outcome that was biased in favour of screening, mainly because of differential misclassification of cause of death.

TL;DR: A small effect of breast cancer screening on breast cancer mortality in women aged younger than 50 years compared with older women and various possible reasons have been suggested are suggested.

Male Breast Cancer: A Population-Based Comparison With Female Breast Cancer
TL;DR: Age-specific incidence patterns showed that the biology of male breast cancer resembled that of late-onset female breast cancer, and similar breast cancer incidence trends among men and women suggested that there are common breast cancer risk factors that affect both sexes, especially estrogen receptor-positive breast cancer.

Indicators of prognosis in node-negative breast cancer
TL;DR: It is concluded that a prognostic index that includes indicators of the proliferative activity of tumor cells may be able to identify women with node-negative breast cancer in whom the risk of recurrence is sufficiently low that adjuvant chemotherapy can be avoided.

Survival Curve for Cancer Patients Following Treatment
Joseph Berkson,Robert P. Gage +1 more
TL;DR: A simple function, in terms of two physically meaningful parameters, has been evolved, which fits survivorship data very well and can be used to compare succinctly the mortality of two groups, different in respect of treatment, type of cancer, or other characteristics.

Evidence on screening for breast cancer from a randomized trial.
TL;DR: Based on current findings in the HIP study, there appears to be strong support for periodic screening at ages 50 years and over with clinical examination and mammography; to justify screening under 50, new information from other studies is required.

Treatment of Early Breast Cancer: A Report after Ten Years of a Clinical Trial
TL;DR: In patients with clinically involved axillary nodes there was a significantly higher incidence of local and distant recurrence in those having a wide excision, and the survival of these patients was significantly less than those who had a radical mastectomy.

TL;DR: The discovery that leaving behind positive axillary nodes has as yet not been influential in enhancing the incidence of distant metastases or the overall proportion of treatment failures and that a disproportionate number of treatments failures in the total mastectomy group occurred in those patients who subsequently required axillary dissection provides reinforcement to the view thatpositive axillary lymph nodes are not the predecessor of distant tumor spread but are a manifestation of disseminated disease.
