pirarubicin and Leukemia--Lymphoid

Eighty-four previously treated adult patients with acute leukemia and malignant lymphoma were treated with (2"R)-4'-O-tetrahydropyranyladriamycin (THP). THP (10-55 mg/m2) was administered by i.v. bolus injection daily for acute leukemia, and according to three different schedules for malignant lymphoma: daily, weekly or once every 3-4 weeks. Complete and partial remission (CR and PR) were achieved by 1 (5%) and 3 of 19 patients with acute myelogenous leukemia and by 2 (13%) and 3 of 15 patients with acute lymphoblastic leukemia, respectively. All CRs were in the groups receiving 25 mg/m2 THP daily. CR and PR were achieved by 6 (14%) and 8 of 42 patients with non-Hodgkin lymphoma (NHL) and by 4 (50%) and 2 of 8 patients with Hodgkin's disease (HD), respectively. No particular sensitivity was found among the subtypes of NHL and HD. Response (CR + PR) was noted in 10 (40%) of 25 patients treated every 3-4 weeks, in 1 (17%) of 6 treated weekly, and in 9 (47%) of 19 treated daily. The major side effects were myelosuppression and gastrointestinal toxicities. Alopecia was observed in only 10 (12%) patients. ECG abnormalities were observed in 7 (10%) patients, all of whom had previously been treated with other anthracyclines. No severe cardiotoxicity was observed.

Thirty-eight patients with adult acute lymphoblastic leukemia (ALL) or non-Hodgkin's lymphoma (NHL) were treated intravenously with (2"-R)-4'-o-Tetrahydropyranyladriamycin (THP) at a dose of 10 mg/m2 for 5 consecutive days. Seven complete and 15 partial responses were observed in 35 evaluable patients (overall response rate, 62.8%). Both antitumor activity and antitumor spectrum were similar to those for doxorubicin. Since the patients who had had chemotherapy previously, including other kinds of anthracycline, responded rather poorly to THP, cross-resistance between THP and other anthracyclines may be present. Leukopenia and thrombocytopenia were dose-limiting factors. Nausea and vomiting episodes were mild, and epilation was also minimal. Although the observation period was short and a cumulative dose was not large enough to evaluate cardiotoxicity, there were no abnormal EKG changes or clinical signs of cardiotoxicity in this study. THP is a potent antitumor agent in the treatment of lymphoid malignancies.

Of 3 patients with adult ALL and 23 patients with NHL treated with intravenous administration of 10 mg/M2 of THP for 5 consecutive days, complete remission was observed in 3 patients and partial remission in 14. The antitumor spectrum of THP seemed to be similar to that of Adriamycin from evidence that THP was effective in patients with NHL of diffuse large and mixed cell type. Neither cardiotoxicity nor alopecia was noticed. Anorexia, nausea or vomiting was mild but granulocytopenia and thrombocytopenia were severe in the patients with ALL and leukemic type NHL. Further studies are required for determining cross resistance to other anthracyclines and an optimal dose schedule.
