Feasibility of a cell kinetic-based adjuvant chemotherapy trial in axillary node-negative breast cancer.

Abstract

AIMS AND BACKGROUND Accumulated information on biologic prognostic indicators and predictors of response to different types of treatment in patients with different tumor characteristics has made it possible to design clinical protocols on biologic bases. Among cell proliferation indices, the thymidine labelling index (TLI) has proved to be an independent and consistent prognostic indicator over time. Moreover, experimental and retrospective analyses of clinical studies have revealed a direct relation between TLI and response to chemotherapy. On the basis of the results, a prospective clinical protocol on axillary node-negative breast cancer was activated in Italy in 1989. METHODS Patients with low TLI tumors were treated with local-regional therapy alone, whereas patients with high TLI tumors were randomized to receive local-regional therapy followed or not by adjuvant chemotherapy consisting of 6 cycles of CMF. RESULTS AND CONCLUSIONS The present paper reports on the feasibility of a prospective clinical protocol based on a subgroup of patients with specific pathologic (node negative) and biologic (rapidly proliferating) breast cancers. However, patient eligibility was only 11%.
