We reported rare manifestations of adult T cell lymphoma/leukemia. Patient was 41 year-old woman who has had progressive alopecia from childhood and developed multiple huge tumors (largest 10 x 15 cm) of scalp and wide destruction of cerebral bone at age of 39. A few abnormal lymphocytes (10%) appeared in the peripheral smear. Surface markers of peripheral lymphocytes showed two populations of CD4+/CD8- and CD4+/CD8+. HTLV-1 proviral DNA was demonstrated in the peripheral lymphocytes. Serum anti-ATLA antibodies was positive (X80). Biopsy of tumor revealed diffuse and large cell type of malignant lymphoma. Magnetic resonance imaging of head showed that tumors lysed the bone and invaded into cerebral regions. She was treated with CHOP regimen and irradiation, resulting of decreased tumor size and population of CD4+/CD8+.

We have retrospectively analyzed the characteristics of 24 adult patients affected with non-endemic Burkitt's lymphoma (BL) and Burkitt cell acute leukemia (L3 ALL). The median age of the entire group was 29 years with a male preponderance (75%). Median LDH value was 580 mU/mL. Test for HIV-antibodies was carried-out in 16 patients; 5 of them (21%) showed HIV positive. CNS was involved in 25% of patients at diagnosis. In all cases studied for karyotype, the t(8;14) translocation was evident. As to therapy, 5 patients were not evaluable for early death, 12 were given an intensive ALL program, 5 a cyclic chemotherapy and 2 a new protocol alternating high-dose cyclophosphamide, high-dose cytarabine with mitoxantrone and the CHOP regimen. The overall complete remission rate was 42%; among 7 remitters, 4 have relapsed so far within a median time of 6 months. Three of 13 (23%) patients with lymphoma presentation are long remitters and may be cured; all cases had stage II disease and low LDH at diagnosis (less than 250 mU/mL). No patients with Burkitt's leukemia survive. CNS disease (8 cases) and septic shock (6 cases) were the most frequent terminal events. In our experience, the prognosis of advanced stage BL and L3 ALL in adults does remain dismal; the high prevalence of CNS disease and HIV-positivity may have contributed to the poor outcome.

In a group of 9 patients with chronic lymphocytic or lymphoplasmocytic leukaemia in clinical stage from 2 to 4 (classification of Rai et al.) 8 various CHOP programmes (cyclophosphamide, hydroxyldaunomycin, oncovin, prednisone) were used. In 6 cases (67%) partial remission was obtained, with normalization of peripheral blood and bone marrow patterns, with statistically significant decrease of the proportion of cells forming rosettes with murine erythrocytes, and with reduction or full normalization of the size of previously enlarged lymph nodes. In one case the control examination of a lymph node failed to demonstrate the previously present clone of cells with chromosomal aberration, although in histological examination the diagnosis of lymphoplasmocytic lymphoma was maintained. In the remaining 3 cases no partial remission was noted, and in one case progression was recognized. We think similarly as the French haematologists studying chronic lymphatic leukaemia, that the CHOP programme is effective in the treatment of chronic lymphatic or lymphoplasmocytic leukaemia.

Children with "poor-risk" nonlymphoblastic lymphoma, especially those with marrow or nervous system (CNS) involvement at presentation, have fared poorly even on aggressive chemotherapy regimens. We report here the results of a pilot study of 30 children treated with a highly intensive chemotherapy regimen. This regimen includes an intensive Induction Phase consisting of three cycles of CHOP therapy (cyclophosphamide, doxorubicin, vincristine, and corticosteroids) as well as intensive intrathecal therapy with each cycle. This is followed by a CNS Consolidation Phase consisting of a single cycle of CHOP therapy with five intrathecal doses of "triple" chemotherapy (methotrexate, cytosine arabinoside, and hydrocortisone). Thereafter, a Maintenance Phase consists of alternating cycles of 1) cytosine arabinoside and 6-thioguanine, 2) oral methotrexate and VP-16, and 3) CHOP, for a duration that varied from 36 to 72 wk. Neither debulking surgery nor radiation therapy were recommended. There were 20 patients with Stage III disease (St. Jude's Staging System) and an additional ten patients with bone marrow and/or CNS involvement. The latter group included six patients with B-cell leukemia, three of whom also had CNS disease at presentation. Two additional patients had CNS disease without marrow involvement. Twenty-nine of 30 patients achieved a complete response. Six patients died with recurrent or progressive disease. Twenty-three patients are alive without any adverse events between 21 and 65 mo after diagnosis, with the median time of survival not yet reached (at least 32 mo). All seven adverse events occurred within 7 mo of diagnosis. Event-free survival for all patients is 77%, for Stage III patients is 80%, and for patients with marrow and/or CNS involvement is 70%. This pilot study offers encouragement for improvement in the prognosis of children with "poor-risk" nonlymphoblastic lymphoma and merits evaluation in a Phase III randomized trial in the multicenter cooperative group setting.

Treatment results remain very poor for some clinical and histopathologic subsets of patients with aggressive non-Hodgkin's lymphoma. We treated 21 such patients with a high-dose combination chemotherapy regimen [Mega-COMLA (cyclophosphamide, cytarabine, vincristine, and methotrexate followed by leucovorin and prednisone) + CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone)] in an attempt to improve disease-free survival. Neoplasms were classified using the Lukes-Collins system. Eight patients had T-cell lymphomas (convoluted lymphocytic lymphoma, four patients; T-cell lymphoma/leukemia, one; and peripheral T-cell lymphoma, three), eight had B-cell lymphomas (immunoblastic sarcoma, five patients; small noncleaved follicular center cell, one; and large noncleaved follicular center cell, two), and five had nontypable large noncleaved cell lymphomas. All patients were previously untreated; 18 of 21 patients had clinical stage III or IV disease. Following induction therapy (4-8 weeks' duration), 16 patients (76%) achieved complete remission, while three had partial remission. Two patients died of sepsis during induction therapy. Eleven of 16 complete responders (69%) remain in complete remission after a median follow-up of 35 months. The actuarial 3-year survival rate is 51% for the entire group. Myelosuppression with this regimen was severe and prolonged, with a median duration of neutropenia (less than 500 cells/microliter) of 14 days. Seven patients (33%) developed severe neuropathy following induction treatment. High-dose induction therapy with this regimen resulted in a high complete remission rate with manageable toxicity. Survival results are encouraging when compared retrospectively to our patients with similar poor-prognosis histologies treated with standard combination chemotherapy. However, the value of this intensive therapy, relative to newer ("third-generation") regimens, can only be established by prospective randomized studies.

5 patients with hairy-cell leukaemia were treated with chemotherapy. 3 of them received multiple courses of CHOP (cyclophosphamide-doxorubicin-vincristine-prednisolone); 1 patient received cyclophosphamide monotherapy for 6 months. The 5th patient developed a Mikulicz's syndrome after splenectomy and was initially treated with cyclophosphamide monotherapy, then received 1 course of CHOP, and finally 9 courses of intermediate-dose methotrexate. 1 complete remission (45 months+) and 3 partial remissions (75+, 68, 32+ months) were observed, while 1 patient had progressive disease. Our results indicate that chemotherapy may be a valuable alternative to alpha-interferon in the treatment of hairy-cell leukaemia progressing after splenectomy.

Demethoxydaunorubicin (DMDR), a new anthracycline available both for intravenous and oral administration, was given in 14 cases of leukaemia, non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM) replacing either daunorubicin (DNR) or doxorubicin (DOX) in conventional chemotherapy regimes. In acute leukaemia (6 myeloblastic and 1 common lymphoblastic) there were 5 complete (CR) and 2 partial (PR) remissions; one patient, previously brought into remission with a regime including i.v. DMDR was thereafter maintained in CR with oral DMDR. Among the patients treated with the oral DMDR, 2 NHL cases were treated; 1 patient had a sustained remission of 12 months so far, with DMDR alone; another patient had a CR with a combined regime. In MM, one patient with very advanced disease treated with i.v. DMDR/CHOP did not respond, but three cases treated with oral DMDR plus other drugs showed a partial remission. Toxic effects were limited to brief episodes of nausea and vomiting in a few i.v. treated patients; a prolonged bone marrow depression was observed in one case only. No cardiotoxic effect was recorded.

Burkitt's lymphoma was first reported by Burkitt in 1958 as a sarcoma involving the jaw in African children with characteristic symptoms. Forty three Japanese cases have been reported since the first description by Oboshi et al. in 1969. We report a case of Burkitt's lymphoma with left total ophthalmoplegia. A 73-year-old Japanese female was admitted in Sadamoto Hospital on July 11, 1983 with a two-week history of headache, ptosis and double vision. The patient was exposed to the atomic bomb in Hiroshima and had ten-year history of hypertension. On admission, physical examination showed hypertension and neurological examination revealed only left total ophthalmoplegia (such as left ptosis, external ophthalmoplegia, mydriasis and deficit of light reflex). Plain X-ray film and enhanced CT scan showed no remarkable abnormalities. Laboratory examinations revealed high serum levels of GOT(51 K.U.) and LDH (1300 U.). Left carotid and right retrograde branchial angiograms showed no remarkable abnormal findings. While the patient was treated only conservatively, left abducent and trochleal nerve palsy appeared on August 5, 1983. On plain and enhanced CT scans at the time, abnormal density mass with bone destruction of the left sphenoidal sinus was demonstrated. Biopsy specimen from the left sphenoidal sinus showed lymphosarcomatous cells. Peripheral blood and bone marrow smears showed lymphoma cells which are compatible with L3-Burkitt's type according to FAB leukemia classification. The patient was diagnosed as leukemic transformation of Burkitt's lymphoma and treated with CHOP; Cyclophosphamide (C), Hydroxydaunorubicin(H), Vincristine (O), and Prednisolone (P).(ABSTRACT TRUNCATED AT 250 WORDS)

Forty years ago, nitrogen mustard was first used in the treatment of a group of six patients with neoplastic diseases, including lymphosarcoma and Hodgkin's disease at Yale University. Since then different kinds of chemotherapeutic agents have been discovered, which clinical efficacy was reviewed as a single agent and in combination. Especially over the past two decades, the management of malignant lymphoma has improved significantly with combination chemotherapy. Now there are several potentially curative regimens, such as MOPP therapy for Hodgkin's disease, and MOPP (or C-MOPP), CHOP (or HOP), BACOP and COMLA for diffuse histiocytic lymphoma. There are recent trends to include methotrexate in combination and to use two non-cross-resistant regimens alternatively (CVP/ABP, MOPP/ABVD) for improving complete remission rate and remission duration. Treatment for favorable histologies, and clinical features and treatment of adult T-cell leukemia lymphoma were also briefly reviewed.

The treatment strategy for adult T-cell leukemia has not been established. CHOP derived combination chemotherapy protocols such as VEPA and VEPAM have failed to yield high complete remission rates and long survivals. Second or third generation combination chemotherapy regimens using alternative non-cross resistant drugs also have not achieved satisfactory results. A new multi-institutional trial attempting to increase dose intensity supported by granulocyte colony-stimulating factor is bringing improved remission rates and survival times. Other strategies using autologous bone marrow or peripheral blood progenitor cells should be studied as a next step.
