title: Cisplatin containing chemotherapy influences HLA-DR expression on monocytes from cancer patients.
abstract: The effect of cisplatin-containing chemotherapy regimen was evaluated on the expression of HLA-DR antigen in peripheral blood monocytes from patients with lung (LCP) and colorectal (CCP) cancer. Chemotherapeutic schedules employed in patients were etoposide and cisplatin for LCP and 5-fluorouracil and cisplatin for CCP. The results obtained showed a diminished percentage of monocytes expressing HLA-DR antigen in LCP (52.4 +/- 2.6, p < 0.004) and CCP (50.1 +/- 2.1, p < 0.001) respectively versus healthy donors (71.0 +/- 1.1%), and that their values increased during chemotherapy, raising them up to control level after the second cycle of treatment, independently of the course of the cancer growth. We conclude that both modalities of treatment allowed an increase of monocytes expressing HLA-DR antigen, suggesting that this effect may be due to cisplatin action.
