[Relationship between the size of the primary tumor, the presence of lymph node metastases and the survival of breast cancer patients].
An analysis is given of 449 case reports of patients with nodular breast cancer for the period from 1953 to 1967, who showed one tumor node. Most of patients (68%) were radically operated upon, tumor size being 1--4 cm. This is characteristic of patients both with and without metastases in lymph nodes. An average tumor size in the presence of metastases was 3.6 cm, without metastases--3.1 cm. With increasing tumor size the number of patients with lymph node metastases increases too. Metastases were found in 22.2% +/- 13.8% of patients with the tumor up to 1 cm, in 43.4% +/- 5,4% of patients with the tumor up to 1--2 cm. A five-year survival depends on tumor size and, to a greater extent, on the presence of metastases in lymph nodes.
