ABSTRACT
PURPOSE:
Malignant cells from non-Hodgkin's lymphomas (NHL) have been shown to express the somatostatin receptor on their cell surface and most NHL are visible on somatostatin radioscintigraphy scans. This provided the rationale to conduct a phase II trial of a somatostatin analog in patients with B- and T-cell lymphoproliferative disorders. PATIENTS ANDMETHODS:
Sixty-one patients with measurable or assessable lymphoproliferative disorders (31 stage III or IV low-grade NHL; 21 chronic lymphocytic leukemia [CLL]; and nine cutaneous T-cell NHL [CTCL]) were enrolled. Patients were treated with somatostatin 150 micrograms subcutaneously (SQ) every 8 hours for 1 month. Patients with stable or responding disease received 2 additional months of therapy; those who responded after 3 months were treated for an additional > or = 3 months.RESULTS:
Sixty patients were assessable for toxicity and 56 for response. There were no complete remissions. In the low-grade NHL group, 36% (10 of 28 patients; 95% confidence interval [CI], 19% to 56%) had a partial remission. Forty-four percent (four of nine; 95% CI, 14% to 79%) of patients with CTCL had a partial response. No patients with CLL had a partial remission. Among 45 patients with stable disease or a partial remission, the mean time to progression (TTP) was 10.9 months (median, 6.2; range, 1.6 to 48.5). The drug was well tolerated, with the most common side effects being diarrhea and hyperglycemia.CONCLUSION:
Somatostatin at a dose of 150 micrograms every 8 hours is well tolerated and has activity in low-grade NHL.
