Systemic chemotherapy alone for patients with non-acquired immunodeficiency syndrome-related central nervous system lymphoma: a pilot study of the BOMES protocol

BACKGROUND: Anecdotal reports have suggested that systemic chemotherapy with agents that better cross the blood-brain barrier may result in long term disease remission in some patients with central nervous system (CNS) lymphoma. This treatment strategy has the advantage of sparing patients the late neurologic complications from brain irradiation. METHODS: Eligible patients were required to 1) have tissue-proven and measurable non-acquired immunodeficiency syndrome (AIDS)- related primary or metastatic CNS lymphoma; 2) have normal hemogram, renal function, and hepatic function; 3) be age < or = 75 years; and 4) have provided informed consent. Patients with lymphoblastic lymphoma or patients who previously had been exposed to nitrosoureas, etoposide, or high dose methotrexate were not eligible. The systemic chemotherapy (BOMES regimen) included carmustine, 65 mg/m2/day, intravenously (i.v.) on Days 1-2; vincristine, 2 mg/day, i.v. on Days 1 and 8; methotrexate, 1.5 g/m2, i.v. on day 15 followed by leucovorin rescue; etoposide, 50 mg/m2/day, i.v. on Days 1-5; and methylprednisolone, 200 mg/day, i.v. on Days 1-7; repeated every 4 weeks (BOMES regimen). Four doses of intrathecal methotrexate were given to patients who had involvement in the cerebrospinal fluid. RESULTS: Between March 1991 and March 1997 a total of 19 patients were enrolled on the study. There were 13 men and 6 women, with a median age of 57 years. Fourteen patients had primary CNS lymphoma and 5 patients had concurrent extra-CNS lymphoma. Nine patients previously had been treated by radiotherapy (four patients), chemotherapy (three patients), or both (two patients). There were 11 complete remissions (CR) (57.9%) and 5 partial remissions (26.3%), with a total remission rate of 84.2%. One patient had had progressive brain lymphoma during systemic chemotherapy with the conventional cyclophosphamide, doxorubicin, vincristine, and prednisolone regimen, but achieved CR soon after the regimen was changed to BOMES. The median time to progression of the responders was 6 months. At last follow-up, 4 patients were alive without lymphoma at 10, 47, 64, and 66 months, respectively. There were two treatment-related deaths due to sepsis. Another two patients died of fulminant hepatitis that most likely was chemotherapy-related reactivation of chronic B viral hepatitis. CONCLUSIONS: The authors believe systemic chemotherapy alone may result in long term disease remission in some select patients with non-AIDS-related CNS lymphoma. Further investigation for better protocols is mandatory.     

Features of the lateralization of speech function in stutterers as a function of the sex of the subjects

BACKGROUND: To analyze the response to eradicative therapy and prognostic factors in 52 patients with primary gastrointestinal lymphoma (PGIL) diagnosed at a single institution in a 13 year period. PATIENTS AND METHODS: The main clinical, biological and evolutive data were recorded. Pathologic diagnosis of PGIL was made according to the Working Formulation. Clinical stage was determined by the Ann Arbor system modified by Mushoff. The results of therapy as well as the influence of such characteristics on complete remission (CR), disease-free survival (DFS) and overall survival (OS) were studied. RESULTS: Mean age of the series was 53 years (SD 15). Thirty patients were males. HIV infection preceded PGIL diagnosis in 10 cases. Seventeen had bad performance status (ECOG 2-4) and 30 B symptoms. The PGIL localization was gastric in 31 cases and 29 had a low grade malignant lymphoma. B phenotype was demonstrated in 98% and 22 patients presented advanced stages (IIE2-IV). Treatment was radical surgery followed by intensive chemotherapy in 32 cases, intensive chemotherapy alone in 17, and surgical resection in 3. CR was obtained in 34 patients and 6 of them relapsed. The projected DFS from CR at 9 years was 72% and OS was 26%. CR and survival were not influenced by PGIL localization and treatment type. The main unfavourable prognostic factors were advanced stage (CR and OS), B symptoms (DFS and OS) and advanced ECOG score (CR, DFS and OS). Previous HIV infection had an independent prognostic influence on both CR and OS. CONCLUSIONS: In patients with PGIL, the achievement of CR, DFS and survival have been independent of the type of eradicative treatment used. Performance status, B symptoms and clinical stage have been the main prognostic factors. HIV infection carried an independent prognostic significance.     

BEAM chemotherapy and autologous haemopoietic progenitor cell transplantation as front-line therapy for high-risk patients with diffuse large cell lymphoma

In two consecutive and unselected cohorts of diffuse large cell lymphoma (DLCL) patients with advanced stage disease (IIB or bulk or more) and aged < 60 years, we compared a standard (MACOP-B for 12 weeks, 60 patients) versus a high-dose chemotherapy programme (8 weeks of MACOP-B plus one or two cycles of intensification with mitoxanthrone, dexamethasone, high-dose Ara-C, and finally BEAM chemotherapy with autologous haemopoietic progenitor cell transplantation, 61 patients). 41 patients (68%) in the standard group and 51 (84%) in the high-dose chemotherapy group, achieved a complete remission (CR) or an uncertain complete remission (CRu) (P = 0.0491). With a median follow-up time of 28 months for the high-dose group and 63.5 months for the standard group, the actuarial estimate of event-free survival (EFS) at 2 years demonstrates a significant benefit (70% v 50%, P = 0.03) for patients treated with the intensive regimen. The analysis of subgroups of patients showed that only high-risk patients (two or three risk factors) benefitted from the high-dose chemotherapy programme. Nevertheless, the overall survival does not show a significant difference between the two treatment modalities. The treatment-related morbidity was similar and the mortality rate was 8% in the standard (MACOP-B) group and 3% in the high-dose chemotherapy programme. In conclusion, our results show that high-dose chemotherapy and autologous stem cell transplantation is a safe procedure which should be considered for the front-line treatment of non-Hodgkin lymphoma patients with poor prognostic features.     

Indications and relative indications for stem cell transplantation in non-Hodgkin's lymphoma

High dose chemotherapy with or without total body irradiation and autologous stem cell rescue has proven to be effective treatment to cure patients with relapsed intermediate grade and high grade non-Hodgkin's lymphoma. Important factors for selection of candidates most likely to do well with these approaches include patients whose disease is responsive to conventional therapy and those who have minimal disease volume at the time of transplant. The treatment-related mortality of autologous stem cell transplantation has diminished from 20% to less than 5% with improved supportive care and selection of patients with less advanced disease. Although the treatment-related mortality of allogeneic stem cell transplantation may be as high as 20-40%, a graft versus lymphoma effect may decrease relapse with the result that overall survival is not substantially different between autologous and allogeneic transplantation. The definitive indications for stem cell transplantation include patients who have relapsed with intermediate or high grade NHL. Relative indications include intermediate/high grade non-Hodgkin's lymphoma patients, "high risk" first complete remission (CR), resistant relapse; low grade non-Hodgkin's lymphoma in sensitive or resistant relapse, advanced disease (sensitive or resistant relapse, transformation), first CR (younger patients). Relative contraindications include specific patient profiles such as bulky high grade lymphoma which progresses on appropriate conventional therapy, poor performance status, active serious infection, serious cardiac, renal, pulmonary or liver dysfunction, active, central nervous system (CNS) disease unresponsive to cranial irradiation/intrathecal therapy. For patients with previous marrow involvement or active marrow involvement at the time of harvest or transplant, "purged" autografts, peripheral blood stem cell transplantation and allografts have been used successfully.     

Nodular histiocytic lymphoma: factors influencing prognosis and implications for aggressive chemotherapy

Twenty-five patients with Stage III and IV nodular histiocytic lymphoma (NH), entered on three different Eastern Cooperative Oncology Group protocols from 1972-78, were analyzed for response and survival. A complete response (CR) rate of 44% was observed, with 40% partial responders (PR). Four of the 11 CRs are continuing in their original remission. Median survival for CRs was 52 months; for PRs it was 30 months. The six patients treated with cyclophosphamide-prednisone had a median survival of 18 months versus 51 months for the 19 patients treated with more aggressive combination chemotherapy programs. No significant difference in survival was noted between those patients with both nodular and diffuse histology and those with a pure nodular pattern. The median survival of the 25 NH patients was 47 months and is similar to a group of 101 patients with nodular mixed lymphoma (NM) entered on the same ECOG protocols during this time. This survival is intermediate between the nodular lymphocytic poorly differentiated subtype and diffuse histiocytic lymphoma. It suggests that patients with NH histologies be treated with aggressive combination chemotherapy programs designed to achieve complete remission and prolonged disease-free survival.     

Treatment of children and young adults with early-stage non-Hodgkin's lymphoma

BACKGROUND: Children and young adults with early-stage non-Hodgkin's lymphoma have an excellent prognosis, but treatment is prolonged and is associated with many side effects. We performed two studies to determine whether therapy could be simplified. METHODS: Between 1983 and 1991, we conducted two consecutive trials in children and young adults (age, <21 years) with early-stage non-Hodgkin's lymphoma. In the first trial, patients were treated for 9 weeks with induction chemotherapy consisting of vincristine, doxorubicin, cyclophosphamide, and prednisone, followed by 24 weeks of continuation chemotherapy with mercaptopurine and methotrexate. Half the patients were randomly assigned to receive involved-field irradiation. In the second trial, after the 9 weeks of induction chemotherapy, the patients were randomly assigned to receive 24 weeks of continuation chemotherapy or no further therapy. RESULTS: A total of 340 patients were enrolled in the two trials, 12 of whom did not have complete remissions. One hundred thirteen patients received nine weeks of chemotherapy without radiotherapy, 131 received eight months of chemotherapy without radiotherapy, and 67 received eight months of chemotherapy with radiotherapy. At five years, the projected rates of continuous complete remission were 89, 86, and 88 percent for the three groups, respectively. At five years, event-free survival among the patients with early-stage lymphoblastic lymphoma was inferior to that among the patients with other subtypes of lymphoma (63 percent vs. 88 percent, P<0.001). Continuation therapy was effective only in patients with lymphoblastic lymphoma. CONCLUSIONS: A nine-week chemotherapy regimen without irradiation of the primary sites of involvement is adequate therapy for most children and young adults with early-stage, nonlymphoblastic non-Hodgkin's lymphoma.     

Autologous bone marrow transplantation in poor-prognosis intermediate-grade and high-grade B-cell non-Hodgkin's lymphoma in first remission: a pilot study

PURPOSE: Using high-dose therapy and autologous bone marrow transplantation (ABMT) to overcome cellular resistance and eradicate minimal disease, we initiated a pilot study during first remission in patients with non-Hodgkin's lymphoma (NHL) to examine whether the long-term disease-free survival (DFS) rate can be improved for patients with poor-prognosis intermediate/high-grade NHL. PATIENTS AND METHODS: Twenty-six patients with advanced-stage diffuse intermediate/high-grade B-cell NHL (including 16 patients with diffuse small cleaved-cell [DSC]) were selected at presentation by histologic and clinical characteristics to have less than a 25% probability of long-term DFS with conventional treatment. After induction chemotherapy, 16 patients were in complete remission (CR) and 10 were in a minimal disease state. Patients were then treated with high-dose cyclophosphamide, total-body irradiation (TBI), and anti-B-cell monoclonal antibody-purged ABMT. RESULTS: Following ABMT, no acute in-hospital treatment deaths occurred, and engraftment of granulocytes and platelets was significantly faster than for patients undergoing ABMT who were in second or subsequent remission. Of 26 patients, 21 remain in CR maintained without continued therapy, three relapsed in sites of prior nodal disease (4.8, 5.4, and 28 months post-ABMT), and two died in remission. The DFS rate is estimated to be 85% at 28 months and thereafter. The median follow-up period for the 21 patients who are alive and disease-free is 32 months. CONCLUSION: This pilot study suggests that consolidation of first remission with ABMT may improve the long-term DFS rate for diffuse intermediate/high-grade NHL patients at high risk for relapse.     

HATP chemotherapy combined with Chinese traditional medications in treating acute promyelocytic leukemia

18 patients with acute promyelocytic leukemia (APL) were treated with HATP (Harringtonine, Adriamycin, Thioguanine, Prednisone) chemotherapy combined with chinese traditional medications. These medications are known to strengthen vital energy, promote blood circulation, remove stasis and clear toxic materials. 16 patients had complete remission (88.8%) and one partial remission with a total effective rate of 94.4%. Complete remission (CR) was achieved after 3 to 4 courses of treatment in most of the cases. 14 patients were still in CR at the completion of this study and the average duration of survival was 40.5 months. With the various therapeutic actions mentioned above, the traditional medications might decrease the toxicity of chemotherapy, reduce its side effects and prevent the occurrence of DIC. The combined use of traditional medications with chemotherapy may increase the rate and duration of CR as well as prolong the survival.     

Laminin inhibits A beta 40 fibril formation promoted by apolipoprotein E4 in vitro

Multidrug chemotherapy with concomitant interferon (IFN)-alpha was performed in a patient with chronic hepatitis lacking the hepatitis Be antigen and malignant lymphoma (ML). Levels of trans-aminases and DNA polymerase (DNA-P) values increased after the fifth course of chemotherapy. Therapy with IFN-alpha for 9 weeks induced a remission in liver disease and complete remission of ML was obtained with subsequent chemotherapy. It was possible to prevent severe liver damage by administering IFN immediately after the elevation of DNA-P. Early introduction of IFN may be effective in the prevention of fulminant hepatic failure from hepatitis from a precore mutant after chemotherapy.     

Burkitt-type lymphoma in France among non-Hodgkin malignant lymphomas in Caucasian children

In a retrospective analysis of 87 cases of Caucasian childhood non-Hodgkin malignant lymphoma (NHML) from Lyon, France, all the case were diffuse lymphomas, but 47 were diagnosed as monomorphic small non-cleaved NHML, pathologically indistinguishable from Burkitt's lymphoma (BL). BL could then be the most frequent childhood lymphoma in France. This homogeneous series allows better definition of the characteristics of BL within NHML. Age distribution is similar to that of endemic BL, with a sex ratio of 3.7/1. Abdominal masses are initially present in 68% of the cases, whereas jaw is involved in only 4%. The disease is characterized by its overwhelming evolution in the absence of therapy. However, complete remission (CR) is usually obtained after the first chemtherapy regimen. Most relapses occur at 3-8 months. Death could be related to cerebrospinal fluid (CSF) involvement, local recurrence or secondary marrow involvement. Ninety per cent of the patients alive with no evidence of disease (NED) 8 months after CR can be considered as definitely cured. Our study on Caucasian children with NHML indicates that, from histological and clinical criteria, nearly half the cases are very similar to African BL. Even though EBV rarely associated with our cases, BL could be a worldwide lymphoma.     

Improved cure rate in children with B-cell acute lymphoblastic leukaemia (B-ALL) and stage IV B-cell non-Hodgkin's lymphoma (B-NHL)--results of the UKCCSG 9003 protocol

From June 1990 to February 1996, 35 patients with B-cell acute lymphoblastic leukaemia (B-ALL) 13 of whom had CNS disease and 28 patients with stage IV B-cell non-Hodgkin's lymphoma (B-NHL) 22 of whom had CNS involvement were treated with a short, intensive multiagent chemotherapy regimen (UKCCSG 9003 protocol) based on the French LMB 86 regimen. Fifty-five were boys. The age range was 11 months to 16.5 years (median 8.4 years). Chemotherapy included cyclophosphamide, vincristine, daunorubicin, high-dose methotrexate (COPADM) and etoposide/high-dose cytarabine (CYVE) with frequent intrathecal (i.t.) triple therapy (methotrexate, cytarabine and hydrocortisone). Cranial irradiation (24 Gy in 15 fractions) was recommended in patients with overt CNS disease. One patient with Wiskott-Aldrich syndrome was withdrawn after entry and has been excluded from the analysis. Ten patients (16%) have relapsed (CNS, four; BM, two; combined CNS and BM, three; and jaw, one) 4-11 months after diagnosis and two patients never achieved complete remission (CR). All have died. In seven of the patients who relapsed, treatment had been modified or delayed because of poor clinical condition. Seven patients (11%) died of toxicity 11 days to 4 months after diagnosis. The cause of death was sepsis (n = 5) or sepsis with renal failure (n = 2). With a median follow-up of 3.1 years from diagnosis (range 9 months to 6.3 years), 43 patients (69%) survive in CR. This study confirms the effectiveness of this regimen with regard to the relapse rate (16%), although the rate of toxic death is of concern.     

Networks of transcriptional regulation encoded in a grammatical model

In a prospective multicenter study 68 out of 158 patients with HIV infection and malignant lymphoma were assigned to a risk-adapted induction therapy using the following algorithm: High-risk patients fulfilled 2 of 3 criteria: T4 lymphocytes <50/microL; WHO activity index 3 or 4; pre-existing AIDS-defining opportunistic infection. Normal-risk patients received 4 to 6 cycles of CHOP chemotherapy; those that achieved complete remission (CR) received zidovudine (500 mg/d) and interferon-alpha maintenance therapy (5 million units three times a week) for one year. High-risk patients received low-dose CHOP or vincristine/prednisone chemotherapy. Supportive care was performed with pentamidine inhalation and G-CSF. Intrathecal (it) methotrexate was given for CNS prophylaxis. The median survival was 634 days for 38 patients of the normal-risk group and 129 days for 30 patients of the high-risk group. 18 high-risk patients treated with low-dose CHOP had better survival (156 days) than 12 patients treated with vincristine/prednisone (72 days p=0.044). 68% of the patients in the normal-risk group achieved complete remission. 5 out of 18 high-risk patients treated with low-dose CHOP achieved complete remission. Three normal-risk patients developed fatal opportunistic infections during chemotherapy. Immune parameters deteriorated after CHOP induction and partially recovered with maintenance treatment. We conclude that the normal-risk patients survived longer than reported in most published studies. Toxicity was low. Low-dose CHOP seems to be superior to vincristine/prednisone therapy in high-risk patients.     

Primary pulmonary lymphoma--clinical review from a single institution in Singapore

Primary pulmonary lymphoma is a rare and vexing subset of extranodal non-Hodgkin's lymphoma. We report 11 cases and provide a brief literature review. We also highlight an unusual case of a relapsed peripheral T-cell primary lung lymphoma that underwent apparent spontaneous remission. Eleven cases of primary pulmonary lymphoma treated in our institution were studied for their clinical characteristics, behaviour, response to treatment and clinical outcome. The median duration of follow up was 26 months. The mean age was in the 50s and the presenting symptoms generally respiratory and non-specific. LDH levels did not correlate with either stage or grade of disease. Lower lobe involvement was most common and nodules and mass-like lesions the main radiologic feature. Small lymphocytic lymphoma accounted for the majority of cases and were indolent in behaviour. Good symptom control and radiologic response was achieved with chemotherapy in disseminated low grade lung lymphomas. Combination chemotherapy was effective in the aggressive lymphomas. In conclusion, Small lymphocytic lymphoma of the lung is an indolent disease with a long symptom-free survival even after recurrence. Our series confirms the clinical characteristics of primary pulmonary lymphoma. The role of Ling Zhi in effecting the spontaneous remission in the peripheral T-cell lymphoma is speculative.     

Studies on the method of the analysis of sapogenin. III. Coulometric titration of diosgenin (author''s transl)

Fifteen of 146 (10%) adult patients with non-Hodgkin's lymphoma showed clinical and pathologic evidence of involvement of the central nervous system (CNS): in 6 patients, the CNS lymphoma was present at the onset of disease, in 3 of them it was the only sign detected. In the remaining 9 cases, CNS involvement appeared during the course of systemic disease. In all cases symptoms related to infiltration of the CNS were associated with advanced disease (stage IV); bone marrow or bone involvement was found in 9 patients (60%). The histologic subtypes were mostly of high-grade malignancy according to the Kiel classification: immunoblastic (3), centroblastic (3), Burkitt type (2), lymphoblastic (1), LP immunocytoma in polymorphic variant (3), unclassifiable (3). The prominent signs and symptoms of CNS lymphoma are listed: the cranial nerve palsies are the most common finding. The principal means of detecting CNS involvement are discussed: cerebrospinal fluid cytology, brain scan and CAT scan were the most useful diagnostic procedures. The reported data allow identification of patients at high risk of CNS lymphoma: this includes histologies of high-grade malignancy, advanced stage of disease, and bone marrow or bone infiltration. Therefore, either intensive systemic chemotherapy or CNS prophylaxis are recommended for patients with high risk of CNS disease.     

Successful treatment of non-Hodgkin's lymphoma of the central nervous system with BMPD chemotherapy followed by radiotherapy

The treatment of patients with primary non-Hodgkin's lymphoma of the central nervous system (PCNSL) is still of limited success, as compared with other extranodal sites. The poor results obtained with radiotherapy alone can be improved by adding chemotherapy reaching a median survival up to over 30 months and 5-years-survival rate up to 35%. The optimal management for patients with CNS relapse of systemic lymphoma remains uncertain and their prognosis is even worse. Here, we describe our preliminary data on the treatment of patients with CNS lymphoma with a new regimen composed of CNS-penetrating drugs, namely: carmustine (BCNU) 80 mg/m2 i.v. dl, methotrexate 1500 mg/m2 over 24h i.v. d2, procarbacine 100 mg/m2 p.o. d1-8, and dexamethasone 3 x 8 mg p.o. d1-14. An average of 3 treatment courses were given under response control seen using CT-scan or NMR. Patients with positive CSF cytology received additionally intrathecal therapy with methotrexate. Until now between March 1994 and September 1997, 7 patients with PCNSL and 4 patients with CNS relapse of systemic lymphoma have been treated. The median age of the patients was 56 (range, 39-74); 5 patients were > or =60 years old. Three patients had multifocal disease. Whole brain radiotherapy with 4000 to 5000 cGy was given in 7 patients (cerebrospinal in 1 patient). Complete response at the end of chemotherapy was achieved in 6 patients, and a partial response in two. Most remarkably, 2 elderly patients (70 and 57 years), 1 patient with multifocal disease and 1 with simultaneous CNS and systemic relapse after chemotherapy had a complete remission lasting for 40 months, and a partial remission lasting for 37 months, respectively.     

Evaluation of primary standard cisplatin-based chemotherapy for clinical stage II non-seminomatous germ cell tumours of the testis

OBJECTIVE: To evaluate the use of primary cisplatin-based chemotherapy before retroperitoneal lymph node dissection (RPLND) in patients with clinical stage II non-seminomatous germ cell tumours of the testis. PATIENTS AND METHODS: Between 1984 and 1992, 55 patients with clinical stage II testicular cancer (12 with stage IIA. 33 stage IIB and 10 stage IIC disease) were treated at Institut Gustave Roussy with primary chemotherapy using three conventional regimens including cisplatin. Patients were assessed 4 weeks after the end of chemotherapy and depending on the response, underwent RPLND; the overall survival and disease progression were monitored. RESULTS: Sixteen (29%) patients achieved a sustained complete remission after chemotherapy only, while 30 (55%) patients required subsequent RPLND for persistent residual tumour masses: nine other patients obtained a clinical partial remission. Six patients who initially had achieved either a clinical complete response (three) or a surgical complete response (one) or a clinical partial response (two) subsequently relapsed. Overall, 52 of 55 (95%) patients remained free of disease 33 to 111 months after the end of treatment. CONCLUSION: These results show that primary cisplatin-based chemotherapy can effect a cure of the tumour in all subgroups of patients with stage II disease.     

ABV方案化疗对艾滋病相关晚期卡波氏肉瘤外周血CD4淋巴细胞的影响

Objective: The combination of highly active antiretroviral therapy (HAART) and chemotherapy with ABV regimen (doxorubicin, bleomycln and vincristine) is a promising approach for the treatment of advanced HIV-related Kaposi's sarcoma (KS). Here we analyzed the relationship between the CD4 lymphocyte cell count and the clinical response to chemotherapy.Methods: The 176 HIV infected patients with advanced KS who failed to respond to prior HAART were selected. All these patients were then preceded to chemotherapy with ABV regimen which was administered at 3 weekly intervals for 6 cycles.For each patient CD4 cell count was done before starting chemotherapy and after finishing 6 cycles of chemotherapy. The difference of CD4 cell counts pre chemotherapy and post chemotherapy was compared with the clinical progress of the patients after 6 cycles of chemotherapy. Results: The overall clinical remission was shown in 93.7% patients. Progressive disease (PD) and no change in clinical condition (NC) was shown in 6.3% patients. The increase in CD4 cell count post chemotherapy was found in 89.8% patients and the decrease in CD4 cell count was seen in 10.2% patients. The difference of the mean CD4call counts for patients in group CR + PR (complete relief + partial relief) before and after chemotherapy was highly significant.The difference of the mean CD4 cell counts for patients in group NC + PD before and after chemotherapy was not significant.The difference in CD4 cell counts in CR + PR and NC + PD groups before and after chemotherapy was highly significant.Conclusion: The HIV related KS patients on HAART benefit from the chemotherapy as it increases the CD4 cell count and it has positive impact on clinical remission of KS.     

Autologous stem-cell transplantation for non-Hodgkin's lymphomas: the role of graft purging and radiotherapy posttransplantation--results of a retrospective analysis on 120 patients autografted in a single institution

PURPOSE: To analyze retrospectively survival and prognostic factors of patients with non-Hodgkin's lymphoma (NHL) autografted from 1979 to 1995 in a single institution. PATIENTS AND METHODS: A total of 120 patients, 64 with aggressive and 56 with low-grade NHL, were autografted. The carmustine (BCNU), etoposide, cytarabine, and melphalan (BEAM) regimen was used in 104. The autograft was marrow in 101 patients. Marrow was purged in vitro by mafosfamide for 63 patients (adjusted dose [AD] in 32; unique dose [UD] in 31); 27 patients received a CD34+-selected graft. Following intensification, 45 patients received additional radiotherapy on previous sites of involvement. RESULTS: Outcome at 5 years for patients transplanted with low-grade NHL in first complete remission (CR1), in first partial remission (PR1), and in second complete remission (CR2) or beyond showed an event-free survival (EFS) of 75% +/- 12%, 46% +/- 18%, and 57% +/- 24%, a relapse incidence (RI) of 21% +/- 12%, 49% +/- 19%, and 43% +/- 25%, and a transplant-related mortality (TRM) of 5% +/- 5%, 10% +/- 7%, and 0%, respectively. For patients with aggressive NHL transplanted in CR1, in PR1, in CR2 or beyond, and in resistant relapse or in primary refractory disease, the EFS was of 73% +/- 9%, 58% +/- 19%, 29% +/- 16%, and 10% +/- 9%, the RI 22% +/- 9%, 14% +/- 9%, 77% +/- 18%, and 66% +/- 20%, and the TRM 6% +/- 6%, 32% +/- 21%, 11% +/- 10%, and 71% +/- 22%, respectively. In patients autografted upfront in first remission, additional radiotherapy was associated with a higher EFS, in univariate (P = .03) and multivariate analysis (P = .02, relative risk [RR] = .021). The role of graft purging with mafosfamide on the outcome reflected by the dose of colony-forming unit-granulocyte-macrophage (CFU-GM) per kilogram infused postpurging was assessed by univariate analysis: patients in first remission who received lower doses of CFU-GM had a lower RI and a higher EFS. CONCLUSION: This retrospective analysis suggests that marrow purging and posttransplant radiotherapy improve the outcome of patients with NHL autografted in first remission.
