Intensive chemotherapy with 1-3 drugs and support with autologous myelopoietic cells extracted from the peripheral blood: the preliminary results

Fourteen patients with different solid tumors have been treated with high-dose combination chemotherapy followed by autologous PBSC support. A total of 15 procedures have been done. 4,5-7 x 10(10) mononuclear cells were obtained through 1-4 leukapheresis using a CS-3.000 continuous flow blood cell separator.

Cells were maintained in standard culture conditions for 3-5 days prior to infusion. Chemotherapy consisted in the administration of 1-3 agents: CPA 80 mg/kg; VP-16, 800 mg/m2; BCNU 700-800 mg/m2, CBDCA 1.000 mg/m2. APBSC were infused 48 hours after the last chemotherapy was given. Patients were maintained in single-bed rooms with standard prophylactic antibiotics, including gentamycin, piperacillin, vancomycin and amphotericin B during the period of aplasia. Currently 5 procedures are available for response and all patients are evaluable for toxicity. Responses have been: 2 complete responses and 3 partial response. All patients entered in aplasia, with 12 infections (73%), 8 bleeding (53%), 4 diarrhea (27%), 2 stomatitis (13%) and 3 renal failure (16%).

Conclusions:

1. Bone marrow recovery after high dose chemotherapy can be shortened with APBSC support.
2. APBSC can be safely maintained using standard culture techniques, thus avoiding the freezing procedure.
