[Methotrexate-induced skin detachment].

The undesirable effects of high-dose methotrexate on integument and mucosa are well-known, but lesions of the skin proper, characterized by distal erythema with desquamation, are rare. We report the case of a male patient presenting with extensive skin erosions after intravenous infusion of a 5 gram total dose of methotrexate to treat high-grade lymphoma. The skin disease was accompanied by renal, hepatic and mucosal lesions, as well as bone marrow aplasia. The mechanism of cutaneous necrosis is uncertain, but it might be due to direct toxicity of methotrexate to the epidermis. The patient was also treated with G-CSF. He recovered from aplasia within 6 days, without infectious complications. Haematopoietic growth factors might have reduced the risk of infection arising from the skin, by shortening the duration of cytopenia.

Prognosis and treatment of lymphoblastic lymphoma in adults: a report on 80 patients.

PURPOSE: We analyzed prognostic factors in 80 adult patients with lymphoblastic lymphoma (LBL). PATIENTS AND METHODS: Twenty-one patients received six monthly courses of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and maintenance chemotherapy for 12 months. The LNH-84 protocol (30 patients) consisted of four courses of high-dose CHOP followed by consolidation for 4 months. Both FRALLE (22 patients) and LALA (seven patients) protocols were two intensive chemotherapy regimens for acute lymphoblastic leukemia (ALL) that included an induction with daunorubicin, vincristine, cyclophosphamide, prednisolone (and asparaginase for the FRALLE regimen), consolidation, and maintenance chemotherapy that lasted for 2 years. RESULTS: Sixty-six patients (82%) achieved a complete remission (CR). The CR duration rate and overall survival rate at 30 months were estimated to be 46% and 51%, respectively, with a median follow-up of 55 months. Only two of 37 relapses occurred after 26 months. Chemotherapy protocol did not influence CR rate, CR duration, and survival. A higher CR rate was associated with an age of less than 40 years, lactic dehydrogenase (LDH) level of less than two times the upper limits of normal, and no or one extranodal site of disease. Short survival was associated with a failure to achieve CR, age older than 40 years, B symptoms, LDH level more than two times the upper limits of normal, and hemoglobin level of less than 100 g/L. Bone marrow involvement had no prognostic value. We could not evaluate precisely the prognostic value of Ann Arbor stage because inclusion criteria differed among treatment groups. CONCLUSION: Our findings suggest that age and LDH are two important pretreatment prognostic factors for adult LBL, and that the optimal prognostic staging system remains a controversial issue.

Autologous peripheral blood stem cell transplantation after high dose therapy in patients with advanced lymphomas.

Thirty-eight patients with refractory or relapsed non-Hodgkin's lymphoma (19 patients) or Hodgkin's disease (19 patients) were treated with salvage therapy. The peripheral stem cell collection was performed during hematologic recovery after myeloablative chemotherapy. In eight patients with Hodgkin's disease the number of CFU-GM collected was less than 0.5 x 10(4)/kg and these patients were excluded for stem cell transplantation. In the remaining 30 patients, a median of 4 x 10(4) CFU-GM/kg was collected (range 0.8-100 x 10(4)/kg) by three leukaphereses in 25 patients and six to 11 leukaphereses in five patients. Conditioning regimens were CBV (eight), BEAM (six), BEAC (10) and cyclophosphamide + total body irradiation (TBI) (six). Without TBI, the mean time for reaching a granulocyte count greater than 0.5 x 10(9)/l was 18 days and for a platelet count greater than 50 x 10(9)/l was 19 days in 23 out of 24 patients. With TBI, in five patients the mean time for reaching a granulocyte count greater tahn 0.5 x 10(9)/l was 37 days and for a platelet count greater than 50 x 10(9)/l was greater than 100 days. Complications were minor. There was only one toxic death. The outcome in these patients was similar to that observed in patients who received autologous bone marrow transplantation for advanced lymphomas. In conclusion, we observed good hematologic recovery except when TBI was used in the conditioning regimen.

Effects of escalating doses of recombinant human interleukin-2 in correcting functional T-cell defects following autologous bone marrow transplantation for lymphomas and solid tumors.

High-dose chemotherapy followed by autologous bone marrow transplantation (ABMT) in the treatment of malignancies is often associated with immune deficiency following transplantation, possibly contributing to tumor relapse or fatal infection. Interleukin 2 (IL-2), which enhances major histocompatibility complex (MHC)-unrestricted cytotoxicity in vitro, can be applied in vivo as immunotherapy to reduce these potential complications. Recombinant human IL-2 (rIL-2) was administered by continuous i.v. infusion for four courses in 19 patients following ABMT for lymphomas and solid tumors. The patients were assigned to five groups of escalating doses of rIL-2 ranging from 3 to 30 x 10(6) IU/m2/day. The immunological effects and toxicity were monitored. After a transient reduction of lymphocytes in the peripheral blood, a significant lymphocytosis was observed during the rIL-2 infusion with an augmentation of CD2+, CD25+, and CD8(+)-Ia+ T cells and a dose-related increase of CD56+ lymphocytes. Natural killer (NK) activity appeared enhanced in patients treated with as little as 6 x 10(6) IU/m2/day. No statistically significant increase in lymphokine-activated killer (LAK) activity was seen after rIL-2, when compared to LAK activity following ABMT prior to rIL-2 administration. Administration of exogenous rIL-2 to patients who have undergone ablative chemotherapy and ABMT has a role in restoring defective T-cell function. Further trials defining those patients most likely to benefit from rIL-2 integrated with ablative chemotherapy and ABMT are now warranted.

Hodgkin's disease, clinical stages I, II A-B and IIIA. Results of brief chemotherapy followed by irradiation.

From October 1980 to September 1985, 152 patients with Hodgkin's disease (HD) in clinical stages (CS) I, II A-B and IIIA were treated with combined modality therapy (CMT): brief chemotherapy (CT) followed by radiotherapy (RT). CS IA and IIA cases received 3 cycles of MOP, while CS IB, IIB and IIIA cases were randomly assigned to receive MOP or MOP alternating with ABVD (4 cycles). Irradiation was delivered according to the areas initially involved and response to CT. CS I and II subjects in complete remission (CR) received localized fields, whereas CS I, II and IIIA subjects in partial remission (PR) received extended fields, with subtotal nodal RT for CS I and II and CS IIIA without pelvic involvement and total nodal RT for CS I and II below diaphragm and CS IIIA with pelvic involvement. Following CT, CR was 60% (IA-IIA: 71.5%, IB-IIB: 37%, IIIA: 55.5%), PR 35.5% and failure 4.5%. After CT and RT, CR was 98% (IA-IIA: 100%, IB-IIB: 95.5%, IIIA: 94.5%). Responses were similar using MOP and MOP/ABVD regimens. Fifteen patients relapsed (10%) and 15 died, 11 due to HD and 4 due to other causes, while after 7 years overall survival and relapse free survival were respectively 87% and 82% (IA-IIA 90% and 85%, IB-IIB: 80% and 80%, IIIA: 87% and 62%). Results were equivalent irrespective of CT regimen.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hodgkin's disease associated with HIV infection: clinical characteristics and development. French registry of tumors associated with HIV infection].

From May 1987 to July 1990, 45 cases of Hodgkin's disease (HD) were recorded by the French Registry of HIV-associated tumors. Thirty-nine patients were male and median age was 30 years. Twenty-two cases had mixed cellularity type (MC), 18 nodular sclerosis, two lymphocyte depletion and three were not classified. Thirty-four patients had advanced HD clinical stages (CS III and IV). Thirty-six patients (80%) presented with B symptoms. Bone marrow involvement was diagnosed in 12 patients. Mediastinal involvement was present in only 4/30 patients (12%). Risk groups for AIDS were homosexuality in 18 cases, intravenous drug abuse in 17, both in one, and other in nine cases. In 40 cases (89%), HD occurred before any AIDS-related episode. Median CD4 cell count at HD diagnosis was 304 cells/microliters. Seventy-nine percent of the patients achieved complete remission with standard therapy, but hematological and infectious complications were very frequent. The rate of progression to AIDS was 71% at three years and opportunistic infections (mainly pneumocystis carinii pneumonia) were the most frequent cause of death. Overall two-year survival was 41% (78% for patients with initial CD4 cell count higher than 300 cell/microliters and 0% for those with CD4 cell count lower than 300/microliters). HD-HIV has a specific clinical profile as compared to primary HD, with a predominance of MC type and advanced clinical stage, without mediastinal involvement (88%). This study provides a basis for future clinical trials on HD-HIV: intensity of chemotherapy should be adapted to CD4 cell count; pneumocystis carinii prophylaxis is mandatory in all cases. Zidovudine should be included during and after HD treatment; the potential role of hematological growth factors has still to be evaluated.

The significance of a residual mediastinal mass following treatment for aggressive non-Hodgkin's lymphomas.

The chest radiographs of 252 patients with aggressive non-Hodgkin's lymphoma, prospectively treated according to one of three protocols of combination chemotherapy, were reviewed to determine the incidence and prognostic significance of mediastinal abnormalities following treatment. Residual mediastinal masses were defined as any abnormality, greater than 2 cm in diameter, that had initially responded to chemotherapy and then remained stable in size for at least three months after its maximal response, together with the disappearance of all other clinical and biological signs of active lymphoma. At the end of treatment, 21 (8%) patients had some residual mediastinal abnormality. The predominant histological pattern was the diffuse large cell subtype (p less than 0.001). Disease free survival and overall survival for these patients were similar to those observed among patients in complete remission without a persisting radiological mass after treatment. We conclude that mediastinal residual masses after completion of treatment for aggressive lymphoma are frequent and do not indicate a poorer prognosis. Such patients can be observed clinically without any need for additional chemotherapy or radiotherapy.

Cardiopulmonary toxicity after three courses of ABVD and mediastinal irradiation in favorable Hodgkin's disease.

The combination of chemotherapy and radiotherapy in Hodgkin's disease has been associated with iatrogenic effects. Forty adult patients were studied to evaluate the early toxicity following three courses of ABVD (cumulative dose of doxorubicin [Adriamycin] 150 mg/m2, and bleomycin 60 mg) and mediastinal irradiation at 40 Gy. Cardiopulmonary toxicity was assessed from six months to three years after completion of irradiation. Of the 40 patients, all of whom were in complete remission from Hodgkin's disease, 6 experienced dyspnea on exertion. In studies related to Cardiac toxicity, the left ventricular ejection fraction ranged from 50 to 77% (mean 63%); 8 patients had a minor pericardial effusion, 4 had valvular calcification, and 6 had minimal cardiac abnormalities. With regard to pulmonary toxicity, CT scan showed a small pleural effusion with pleural thickening in 19 patients and mediastinal or apical fibrosis in 15 patients. The total pulmonary capacity value was low (less than 80%), in 19 patients, and decreased carbon monoxide diffusion capacity (less than 70%) was found in 10 patients. We conclude that early cardiac toxicity was absent despite the use of Adriamycin and mediastinal irradiation. Pulmonary toxicity was present but minor, and it may decrease with the use of smaller fraction sizes for mantle field irradiation.

Surgical restaging of advanced Hodgkin's disease after first line chemotherapy.

47 patients with stages IIIB and IV Hodgkin's disease underwent laparotomy with splenectomy as restaging procedure after first-line chemotherapy (CT) which included 4 cycles of CT ABV/IMEP/PCAV/ABV. After surgical restaging (SR), all patients were scheduled to receive 2 additional cycles IMEP/PCAV followed by TNI 20 Gy and patients with residual clinical abnormality or positive restaging surgery received a 20 Gy boost to these areas. 11 patients (23.4%) were found to have active disease in the spleen (10 patients) and/or the lymph nodes (3 patients) after SR. In the spleen, foci of active disease had a size in millimeters and confirm the limits of clinical restaging. According to the response to CT, 5 of the 35 patients (14%) clinically restaged as good responders had active disease; 6 of the 12 patients (50%) clinically restaged as poor responders had active disease. SR is of interest in selected patients with slowly responding disease to determine the indication of an extended field RT for responding patients and salvage therapy for patients resistant to CT.

[Granulo-monocyte growth factors. Their value in pneumonologic oncologic practice].

Granulo-monocytic growth factors are important members of the family of growth factors which alter the biological response. These factors are glycoproteins and are hormones regulating the production of haematopoietic cells and show their adaptation to possible needs. There are four which are currently well recognised; they are now grouped collectively under the term colony-stimulating factor and of these two, GM-CSF and G-CSF are available thanks to genetic engineering and have reached the stage of therapeutic trials. It is essentially the treatment of solid tumours which should lead to the most profound changes in the current management of cytotoxic drugs because they may allow an increase of the dose and a shortening of the duration of the phase of neutropenia and thus the infection risk. In therapeutic pneumonology they would be able to be used as an adjuvant to chemotherapy in small cell cancers and available in protocols using polychemotherapy with a risk of marrow suppression, indeed even permitting the practice of intensified chemotherapy regimes with or without the support of bone marrow graft. However the clinical experience acquired using growth factors remains limited and is almost exclusively restricted to the haematological domain. Although the secondary effects appear tolerable their harmlessness--and notably the absence of a stimulating effect on tumour growth--remains to be shown before extension of their use will lead to any changes of therapeutic strategies.

Production of a monoclonal antibody (2B44) reactive on a shared epitope on dendritic reticulum cells, smooth muscle cells of vessels and Reed-Sternberg cells.

Lymph node cells from a patient with Hodgkin's disease (HD) were cultured without Epstein-Barr virus (EBV) or leukine adjuvant. A cell line (719-AB) emerged from the culture after four weeks. The cell line express CD20 (79%), CD 21 (30%), CD30 (63%), CD 35 (61%) antigens and weakly CD25 (19%). using Southern Blot technique, the existence of specific EBV DNA and polyclonal immunoglobulin genes rearrangement were observed in the cell line. In order to obtain a monoclonal antibodies (MoAb), mice Balb/C were immunized with this cell line. The splenic cells suspension of immunized animals were fused with the mouse myeloma NS1. Antibody IgM kappa from secreting clones 2B44 was studied using both indirect immunofluorescence with labeled anti-mouse immunoglobulin and immunohistochemistry based on alkaline phosphatase/antiphosphatase complex (APAAP) and ModAMeX technique on a panel of normal or pathological cells. Normal peripheral lymphocytes, monocytes, polymorphonuclear cells, and erythrocytes, did not react. The MoAb 2B44 recognized the dendritic reticulum cells and the smooth muscle cells of vessels on frozen section and paraffin section from HD or reactive lymph nodes. On specially processed paraffin sections (ModAMeX) Reed-Sternberg cells (RSC) were reactive with 2B44 MoAb (in 2 cases out of 5 tested). The molecular weight of the antigen recognized by 2B44 MoAb is of 37 kd. The description of a new epitope shared by different histological components might be of interest for defining a new cluster and better understanding the nature of RSC.

Value of imaging for the diagnosis of residual mediastinal mass in malignant lymphomas.

UNLABELLED: After optimal therapy, residual masses are defined as a mass greater than 2 cm of CT scann, and are present in 15 to 20% of mediastinal lymphomas. We prospectively studied 50 pts with gallium scan (32 cases) and a MRI (41 cases) after the diagnosis of residual masses. There were 38 Hodgkin's disease and 12 non Hodgkin lymphomas; stage I and II: 29 pts; stage III and IV: 21 pts; 32 cases had bulky mediastinal involvement at diagnosis. RESULTS: A negative gallium scan and/or a fibrotic signal on MRI was correlated with a complete remission in 43/50 cases. We observed 2 false positive with gallium scan and 7 cases were MRI was not conclusive with a high signal of indeterminate tissue. CONCLUSION: We propose to perform a gallium scan as soon as the residual mass is detected, than the follow up will be made an MRI. Surgical biopsy must be proposed only when both exams positive or not conclusive.

Treatment of relapsed and refractory Hodgkin's disease with high dose chemotherapy and autologous bone marrow transplantation.

Despite combination of chemotherapy and radiotherapy, some patients with refractory or relapsed Hodgkin's disease (HD) have a bad prognosis. We performed high dose chemotherapy (HDCT) (BCV regimen) with autologous bone marrow transplantation (ABMT) in 26 patients with advanced HD. 11 patients were considered refractory after at least two non cross-resistant chemotherapy regimens and radiotherapy in 8 cases. 15 patients had a poor prognosis relapse (in visceral or irradiated site) after complete remission and they received chemotherapy before ABMT. At the time of transplantation 4 patients had progressive disease with B symptoms and did not respond to HDCT; they all died 3 to 12 months post-transplantation from persistent HD. For the remaining 22 patients, 3 months after HDCT 19 patients (73%) were in complete remission, 2 (8%) in partial remission and one patient died from toxicity. After complete remission 4 patients relapsed at 12 to 18 months and 15 patients are in persistent remission 24 to 46 months after transplantation. These results are encouraging in patients with bad prognostic factors but able to respond to chemotherapy.

Autoimmune hemolytic anemia disclosing Hodgkin's disease associated with Castleman's disease.

A man was admitted for severe autoimmune hemolytic anemia with a mediastinal mass. He required corticosteroid treatment, which altered the first histological examination. Laparosplenectomy was performed and all histological sections were negative, but the hemolytic anemia was not improved. Finally, thoracotomy was performed when the mediastinal mass increased after reducing the corticosteroid treatment. Pathological examination revealed Hodgkin's disease associated with Castleman's disease. After chemotherapy and radiotherapy, the patient remains in complete remission.
