Lymphocyte subpopulations and reactivity in breast cancer recurrence following adjuvant postoperative chemotherapy.

The size of various subset of blood lymphocytes and stimulations with PHA and allogeneic cells (MLC) were examined in 45 women with breast cancer receiving postoperative adjuvant cyclic chemotherapy with chlorambucil, methotrexate, and 5-fluorouracil (LMF). The patients who remained disease-free (n = 19) and those who relapsed (n = 26) during a 4.5 to 6-year follow-up period had similar initial values; and similar kinetics of the examined immunological parameters during and following completion of treatment.
