T-suppressor cell chronic lymphocytic leukemia. Phenotypic characterization by monoclonal antibodies.

A patient with long standing seropositive rheumatoid arthritis developed lymphocytosis which phenotypically involved the cytotoxic/suppressor T-lymphocyte population. There are 10 reported instances of this new disease entity described as "chronic T-cell lymphocytosis with neutropenia" or "chronic suppressor T-cell lymphocytic leukemia." The disease is characterized by hepatosplenomegaly, neutropenia, and the frequent presence of rheumatoid factor without clinical evidence of rheumatoid arthritis. Splenectomy in our patient, as well as in other instances where undertaken, has been ineffective in alleviating the neutropenia. The peripheral blood lymphocytes in our patient were OKT-3+, OKT-5+, OKT-8+, OKT-11+, cALL-, OKT-6-, TdT-. They possessed ADCC but no NK activity and did not suppress PWM-induced B-cell differentiation in spite of the presence of Fc receptor for IgG. Since the lymphocytosis of OKT-8+ cells appears to be clonal, it is suggested that the disease be designated chronic suppressor T-cell lymphocytic leukemia.

Adenosquamous carcinoma of the thyroid after radiotherapy for Hodgkin's disease. A case report and review.

This is a case report of a patient who had received radiation therapy for Hodgkin's disease and 48 years later developed adenosquamous carcinoma of the thyroid gland. Radiation associated thyroid carcinoma is usually of differentiated variety and carried no different prognosis than one not related to radiation. Coexisting adenocarcinoma and squamous cell carcinoma is a very rare event, but makes the prognosis of patients with thyroid carcinoma much poorer. As a result, this kind of patient requires early recognition and aggressive therapy.

Adenocarcinoma

High-dose cytoreductive therapy with autologous bone marrow transplantation in advanced malignancies.

Twenty-one patients with advanced malignancies received high-dose chemotherapy and/or radiotherapy followed by autologous bone marrow infusion. Eighteen patients (85.7%) had fever greater than or equal to 100 degrees F for a median of 6 days; 14 of these patients required broad-spectrum antibiotics for a median of 13 days. Nineteen patients (90.5%) had a granulocyte count less than 500/mm3 for a median of 11 days. Thrombocytopenia (platelet count less than 50,000/mm3) was observed in 18 patients (85.7%) for a median of 14 days. Mucositis and diarrhea were not common, occurring in six (28.6%) and seven (33.3%) patients, respectively. Of the 21 patients studied, 16 were evaluable for tumor response; there were four complete responses and four partial responses, and two patients who showed no change for variable times. Two patients have unmaintained remissions for greater than 2 years. Our response rate (complete plus partial) is 50%. Our study shows that high-dose cytoreductive therapy can be given with moderate toxicity when combined with autologous bone marrow infusion. Because responses in this group of patients are generally of short duration, we believe that patients with advanced malignancies who have had less exposure to therapy or who have a high likelihood of disease recurrence should be considered for high-dose cytoreductive therapy with autologous transplantation.
