Trimethylcolchicinic acid methyl ether d-tartrate (TMCA; NSC-36354) was administered daily by mouth to 71 patients with malignant lymphomas. Partical ( > 50%) responses were observed in eleven of 37 patients with Hodgkin’s disease, two of 22 patients with lymphocytic lymphoma, and one of two patients with mixed cell lymphoma. One complete and three partial responses were noted in nine patients with histiocytic lymphoma. Responses lasted from one to 91 + months (median: four months) and occurred in patients whose disease was resistant to alkylating agents, vinblastine, vincristine, procarbazine, prednisone or BCNU. Toxic effects included leukopenia, thrombocytopenia, nausea, diarrhea, stomatitis, alopecia and dermatitis.

A 30-year-old man underwent orchiectomy in 1962 for a testicular carcinoma composed of choriocarcinomatous and teratocarcinomatous elements. Bilateral pulmonary metastases regressed completely on combination chemotherapy. However, a cerebral metastasis developed in 1963 and caused severe neurologic signs. At craniotomy a large mass of choriocarcinomatous tissue was incompletely removed. Further chemotherapy resulted in a complete remission. The patient remains free of disease more than 16 years later. The treatment of cerebral metastasis is discussed, with emphasis on the possibility of long-term survival and the role of surgery.

Streptozotocin (NSC‐85998) was administered to 53 patients at a dose of 1 to 2 g/m2 weekly. Response to therapy could be evaluated in 39 patients. Responses exceeding 50% in magnitude of tumor reduction were noted in three patients; responses of 25–50% were noted in an additional four patients. Responses were noted in two of four patients with islet cell carcinoma, one of four patients with malignant carcinoid, one of two patients with carcinoma of the lung, one of two patients with squamous carcinoma of the oral cavity, one patient with synovial sarcoma, and one patient with adenocarcinoma of the gallbladder. Renal toxicity was manifested by azotemia in 21 patients and by proteinuria in 28 patients. Elevation of serum glucose occurred in seven patients, but clinical diabetes did not develop. Nausea and vomiting occurred in 40 patients. Hematologic toxicity was noted in four patients.

Polycythemia vera is a condition charac terized by the overproduction of red blood cells, and in many cases of leukocytes and platelets as well, in the absence of hypoxia or other known inciting factors.' The as sociation of polycythemia vera and acute leukemia is well known,2 but the authoris unaware of prior reports of polycy themia vera and Hodgkin's disease con current in the same patient.
