Abstract
In accordance with the Classification of Breast Carcinoma proposed by the Japan Mammary Cancer Society (J. M. C. S.) and the new classification by WHO, a review was made on prognosis and recurrence of various histological types of breast carcinoma that were treated in the Kyorin University Hospital from 1971 to 1978. The five-year survival rate for 69 cases of breast carcinoma was 75%. This series of study includes 4 cases of papillotabular carcinoma, 42 cases of medullary tubular carcinoma and 19 cases of scirrhous carcinoma based on the Japan Mammary Cancer Society classification. The five-year suvival rate was 100% for the group of papillotabular carinoma, 70.7% for that of medullary tubular carcinoma and 73.7% for that of scirrhous carcinoma. Based on the WHO classification, 64 cases were invasive ductal carcinoma and their five-year survival rate was 73.4%. In the cases of this series of study, papillotubular cacinoma, either non-infiltrative or infiltrating, and special types of carcinoma were comparatively few in number. Their prognosis was excellent and no case died of recurrence during the period of 5 years of follow up study. Medullary tubular carcinoma and scirrhous carcinoma (J. M. C. S.) can be put into the category of invasive ductal carcinoma in the WHO classification. Recurrence deaths occurred more frequently in medullary tubular carcinoma than in scirrhous carcinoma. The clinical stage rather than the histological type has a great influence upon the prognosis of patients. The survival period of medullay tubular cprcinoma after surgical operation up to death by cancer recurrence was, on the average, one year longer than that of scirrhous carcinoma. In medullary tubular carcinoma, recurrence occurred frequently by lung, bone and brain metastasis. However, lymphnode metastasis was prominent in scirrhous carcinoma. Local recurrenece was observed in only one case.
