title: Treatment of cutaneous T-cell lymphomas with TP-5. Evaluation of the clinical effect in 8 patients.
abstract: Eight patients with cutaneous T-cell lymphomas (6 patients with mycosis fungoides, 1 patient with Sézary's syndrome, 1 patient with low-grade malignant lymphoma, unclassified) were treated with TP-5, a synthetic pentapeptide having the same biologic activity as the thymic hormone thymopoietin. TP-5 was administered three times weekly at a dosage of 50 mg subcutaneously in 6 patients, 50 mg intravenously in 1 patient, and 100 mg subcutaneously in 1 patient. Clinical evaluation at the end of the trial disclosed improvement in 4 patients (2 patients with mycosis fungoides, 1 patient with Sézary's syndrome, 1 patient with low-grade malignant lymphoma, unclassified), deterioration in 3 patients with mycosis fungoides and no change in 1 patient with mycosis fungoides. As TP-5 evidently exerts some effect on cutaneous T-cell lymphomas, further investigations of its therapeutic potential in this group of diseases seem worthwhile.
