An analysis of 800 breast cancer patients relapsed after radical mastectomy.
The chronology of first recurrences, their topographic distribution and survival from mastectomy were retrospectively studied in a series of 800 mastectomized women with special reference to the relationship between these data and treatment delay, TN categories and free interval. Visceral metastases were more frequent in patients under 50 years, whereas local recurrences were more common in patients over 50. The average free interval was 26 months (over 5 years in 18% of cases) and seemed to be influenced little by the treatment delay or by tumor size; it was shorter in patients under 50 years and shorter still in patients with lymph node involvement at operation. A similar correlation exists between these parameters and survival. The 5 years survival rate of the 800 cases with recurrence was 52%, which is quite different from the rate generally indicated for surgical cases, and much higher than the rate for the natural history of untreated breast cancer. The survival rate in cases with first metastases confined to the soft tissues is much higher than in those with bone and/or with visceral metastases. The survival after recurrence proves to be significantly influenced by the length of the free interval, but much more by the presence or absence of regional lymph node involvement so that the lymph nodes status (N--or N+) turns out to be a prognostic item of primary importance, even after the onset recurrence.
