  • Title: [Prognostic factors in breast cancer and recurrence: study using a quantification theory; type-II].
    Author: Murayama Y, Ogiwara H.
    Journal: Gan No Rinsho; 1984 Apr; 30(4):353-6. PubMed ID: 6727036.
    Abstract:
    The relevance of age, menopausal status, histological type as classified by the Japan Mammary Cancer Society, level of invasion of the primary tumor, invasion of breast cancer cells into blood vessels, invasion of breast cancer into lymphatic vessels, histopathological TNM stage, and SHBG as a prognostic factors was studied to determine their discriminatory powers in predicting cancer recurrence by the type II quantification theory using a computer. We followed up 98 breast cancer patients with 23 recurrent cancers from 3-9 years; the followup period in cases with no recurrence was 10 years after mastectomy. Our study showed that the discriminatory power of those prognostic factors in predicting recurrence were ly (0.44108) greater than histopathological TNM stage (0.39719) greater than menopausal status (0.35701) greater than v (0.30513) greater than level of invasion of primary tumor (0.26072) greater than histological type (0.24311) greater than age (0.23369). The discriminatory rate of these 7 parameters in predicting recurrence was 82.609%. SHBG, which shows hormone dependence of breast cancer, had low discriminatory power.
