Doxorubicin-containing regimen with or without interferon alfa-2b for advanced follicular lymphomas: final analysis of survival and toxicity in the Groupe d'Etude des Lymphomes Folliculaires 86 Trial

PURPOSE: To compare progression-free survival (PFS), overall survival (OS), and toxicity of a doxorubicin-containing regimen administered alone or in combination with interferon alfa-2b (IFNalpha) in patients with low-grade follicular lymphoma (FL) and poor prognostic factors. PATIENTS AND METHODS: Two hundred sixty-eight patients with advanced-stage FL received cyclophosphamide, doxorubicin, teniposide, and prednisone (CHVP) monthly for 6 months, then every 2 months for 12 months. After randomization, 242 patients were evaluated for efficacy: 119 received CHVP alone, and 123 also received IFNalpha at a dose of 5 million units three times weekly for 18 months. RESULTS: After a 6-year median follow-up, the patients treated with CHVP + IFNalpha showed significantly longer median PFS than those who received CHVP alone (2.9 years v 1.5 years, respectively; P = .0002) and significantly longer median OS (not reached v 5.6 years, respectively; P = .008). Although some side effects, which included neutropenia, asthenia, fever, elevated serum transaminase levels, flu-like symptoms, and thrombocytopenia, were more frequently observed in patients who received the combination regimen, these reactions were moderate. IFNalpha was withdrawn because of toxicity in 10% of the patients, and a dosage reduction or temporary suspension was required in 28%. CONCLUSION: With long-term follow-up of 6 years, these results confirm that the addition of IFNalpha to a doxorubicin-containing regimen for patients with advanced-stage and clinically aggressive FL not only increased PFS, as in most other similar trials, but also prolonged OS. Toxicity was moderate. The beneficial effects of this combined chemotherapy and IFNalpha regimen on OS probably reflect the selection of FL patients with poor prognostic factors.     

Adjuvant cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy after radiation therapy in stage I low-grade and intermediate-grade non-Hodgkin lymphoma. Results of a prospective randomized study

BACKGROUND: In a prospective randomized manner, this study evaluated the effect of adjuvant chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone; CHOP) in patients with Stage I non-Hodgkin lymphoma (NHL) who have achieved a complete response (CR) after radiation therapy (RT). METHODS: Forty-four patients with clinical or pathologic Stage I intermediate-grade or low-grade NHL were randomized to receive regional RT alone (median dose, 40 Gy) or regional RT followed by six cycles of CHOP chemotherapy. There were no differences in clinical and pathologic characteristics between the two treatment groups. RESULTS: The median follow-up was 7 years (range, 2-10 years). The actuarial relapse-free survival (RFS) rate for the RT plus CHOP group at 7 years was 83% compared with 47% (P < 0.03) for the RT-alone group. The overall survival (OS) for the two groups was 88% and 66%, respectively (P = 0.2). In patients with intermediate-grade NHL, the 7-year actuarial RFS for RT and CHOP was 86% compared with 20% for RT alone (P = 0.004). The corresponding actuarial survival rates were 92% and 47%, respectively (P = 0.08). In patients with low-grade histologic findings, the addition of adjuvant CHOP did not improve RFS (P = 0.6) or OS. All relapses in this study were at sites remote from the initially involved areas, and in 5 of 11 patients (45%), there were recurrences 5 years or longer after initial treatment. CONCLUSIONS: This study showed that adjuvant CHOP chemotherapy significantly improves RFS in patients with Stage I intermediate-grade NHL who achieve a CR after regional-field RT. The chemotherapeutic regimen favorably affected their probability of survival.     

Prognostic factors for survival of non-Hodgkin's lymphoma patients treated with high-dose chemotherapy and autologous bone marrow transplantation

Prognostic factors to identify patients with high-risk non-Hodgkin's lymphoma (NHL) have recently been developed. We retrospectively investigated the relation between prognostic factors and treatment outcome after autologous bone marrow transplantation (ABMT). From 1984 to 1994, 80 consecutive patients with NHL responding slowly to or relapsing after front-line therapy were treated with high-dose chemotherapy and ABMT. Prognostic factors at the time of diagnosis and of ABMT were related to clinical outcome after ABMT. The cumulative 5-year overall survival (OS) was 51%, progression-free survival (PFS) 41%, and relapse-free survival (RFS) 53%. Absence of B symptoms and intermediate-grade malignancy at first presentation of disease were independently related to prolonged OS (P = 0.02 and P < 0.01, respectively) and prolonged PFS (P = 0.005 and P = 0.01, respectively). At the time of ABMT, first PR or CR, normal LDH levels and tumour stage I + II were associated with prolonged OS (P = 0.0005, P = 0.03 and P = 0.004, respectively). A Coiffier index of 0 or 1, first PR or CR and no extranodal disease involvement were related to prolonged PFS (P = 0.0002, P = 0.005 and P = 0.07, respectively). Treatment-related deaths occurred in 10% of patients. Assessment of disease status, LDH level, tumour stage, extranodal disease involvement and Coiffier index at the time of ABMT is respectively efficient in predicting treatment outcome after ABMT.     

Interferon alpha 2b as maintenance therapy in low grade malignant lymphoma improves duration of remission and survival

We assessed the efficacy and toxicity of interferon alpha 2b (IFN) as maintenance therapy in patients with low grade malignant lymphoma. Between March 1986 and December 1989, 98 patients with low-grade malignant lymphoma in complete remission after conventional chemotherapy were randomly assigned to received IFN, 5.0 MU three times a week for one year, as maintenance therapy (n = 48), or to receive no treatment (control group, n = 50). In March 1994, the median duration of response had not yet been reached in the patients treated with IFN compared to 46 months in the control group. At 9-years 62% of the patients in the IFN arm remain in first complete remission compared to only 25% in the control group (p <.001). In addition, the median duration of survival has not yet been reached in either the IFN arm compared to 74 months in the control group (p <.001). Quality of life was excellent in both groups and severe side effects secondary to IFN treatment were not observed. All patients completed the planned dose of IFN. We conclude that IFN as maintenance therapy in low-grade malignant lymphoma is an excellent therapeutic option because it improves the duration of remission and survival without producing severe side effects or reducing the quality of life.     

BEAM chemotherapy followed by autologous stem cell support in lymphoma patients: analysis of efficacy, toxicity and prognostic factors

In the present paper, we evaluate tolerability, outcome and prognostic factors in patients with poor prognosis non-Hodgkin's lymphoma (NHL) and Hodgkin's disease (HD) when uniformly treated with BCNU, etoposide, cytarabine and melphalan (BEAM) and autologous stem cell transplant (ASCT). On hundred and forty-eight patients with NHL (n = 112) or HD (n = 36) received BEAM followed by infusion of bone marrow (n = 55), peripheral blood stem cells (n = 79) or both (n = 14). Twenty-eight patients had low-grade lymphoma (LGL), 68 intermediate- and 16 high-grade lymphoma (IGL). Within the NHL group, 21 patients were in 2nd or subsequent complete remission (CR) at transplant, 34 had sensitive disease and 11 resistant disease; 46 patients were transplanted in 1st CR due to the presence of > or = 2 adverse prognostic features at diagnosis or to a slow CR. Of the HD patients at transplant 17 had active disease, 16 were in > or = 2 CR and three in 1st CR. The overall percentage of toxic deaths was 5.4%, while in the group of patients transplanted with PBSC it was only 1.3%. NHL patients: 78% were in CR following ASCT, including 25 out of 45 patients (56%) who were transplanted with active disease. Only two of the 11 patients transplanted with resistant disease achieved CR. Incidence of overall survival (OS) and disease-free survival (DFS) at 3 years was 65 and 75%, respectively. As far as histology was concerned, OS was significantly better for patients with LGL in comparison with IGL (88 vs 56%) (P = 0.002). DFS was significantly higher for patients transplanted in first CR or first partial remission (PR) than it was for those transplanted in a later CR or PR (86 vs 53%) (P = 0.02). Multivariate analysis for OS showed that histology, bulky disease, poor performance status at transplant and achievement of CR were independent prognostic factors. In addition, a high number of infused MNC was associated with poor DFS. HD patients: 30 (83%) were in CR after transplantation, with 25 maintaining CR at the end of the study. Only one of the four patients transplanted with resistant disease reached CR. Incidence of OS and DFS at 3 years was 78 and 81%. DFS was similar for patients transplanted with early or late relapse (95 and 93%). With multivariate analysis, the only independent variable for OS was CR after transplant. In conclusion, the present results demonstrate the efficacy and low toxicity of the BEAM regimen in high-risk lymphoma patients with sensitive disease. Other strategies should be investigated for patients with refractory lymphoma.     

Maintenance treatment with interferon alpha-2b in multiple myeloma: a prospective randomized study from PETHEMA (Program for the Study and Treatment of Hematological Malignancies, Spanish Society of Hematology)

The objectives of the present study were to investigate whether interferon alpha (IFN) maintenance could prolong response duration and survival in patients with multiple myeloma (MM) in objective response and to analyze the characteristics of relapse and subsequent survival. From January 1991 to November 1994, 92 patients from the Spanish Cooperative Group PETHEMA with MM in objective response after 12 courses of VCMP/VBAP chemotherapy were randomized to receive IFN maintenance vs no treatment until relapse. Prognostic factors at diagnosis were similar in both groups. IFN was administered at a starting dose of 3 mU/m2 three times per week. The IFN toxicity was moderate with granulocytopenia and fatigue being the most common adverse effects. Median duration of response from randomization until relapse was 13 months in the IFN group vs 7.7 months in the no treatment arm (P = 0.042). Median survival from randomization was 38.8 months for patients given IFN vs 32.7 months for those allocated to the no treatment arm (P = 0.12). Features at relapse were similar in patients who received IFN maintenance and in those assigned to no treatment. Finally, survival from relapse was identical in both groups. In summary, our results show a significant prolongation of response in patients maintained with IFN with no significant influence on survival. In addition, in our series features at relapse and subsequent outcome were similar in both groups.     

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.     

A case of chronic B cell lymphocytic leukemia with expression of CD8 antigen on leukemic cells

PURPOSE: To determine the toxicity and prognosis of patients with relapsed and refractory diffuse aggressive non-Hodgkin's lymphoma (NHL) who underwent an autologous bone marrow transplant (ABMT) using augmented preparative regimens, treated in a major cooperative group setting, and to examine prognostic factors for outcome. PATIENTS AND METHODS: Ninety-four patients with either chemosensitive (50 patients) or chemoresistant (44 patients) relapse, including 22 who failed induction chemotherapy, were treated with high-dose cyclophosphamide and etoposide with total-body irradiation (TBI) (67 patients) or an augmented carmustine (BCNU), cyclophosphamide, and etoposide (BCV) preparative regimen (27 patients) and an ABMT at 16 Southwest Oncology Group (SWOG) transplant centers. All relapsing patients were required to undergo a minimum of two courses of salvage therapy to determine chemosensitivity before transplant. Overall (OS) and progression-free survival (PFS) were determined and a Cox regression model was used to assess potential prognostic variables. RESULTS: Of the 94 eligible patients, there were 10 (10.6%) deaths before day 50 posttransplant because of infection (six deaths), hemorrhagic alveolitis (three deaths), or bleeding (one death). The median 3-year PFS and OS for the entire group was 33% and 44%. For those with chemosensitive disease the PFS and OS were 42% and 55%, whereas for those with chemoresistant disease the PFS and OS were 22% and 29%. The PFS and OS for those failing induction chemotherapy were 27% and 32%. The relapse rates within the first 3 years for the chemosensitive relapse, chemoresistant, and induction failure groups were 61%, 40%, and 59%, respectively. For both PFS and OS, only disease status at transplant was a significant factor in the multivariate Cox model. CONCLUSION: These results single institutional pilot trials exploring augmented preparative regimens. Patients undergoing transplantation for resistant disease, particularly those failing induction chemotherapy, appear to have an improved prognosis as compared with reports using standard preparative regimens. Therapies other than manipulation of standard preparative regimens appear to be required to decrease relapses following autotransplantation.     

MACOP-B and involved field radiation therapy is an effective therapy for primary mediastinal large B-cell lymphoma with sclerosis

PURPOSE: To evaluate the clinical features of presentation and the response to two different third-generation regimens (F-MACHOP and MACOP-B) of primary mediastinal large B-cell lymphoma (MLBCL), a recently defined distinct clinicopathological entity of non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Thirty-seven consecutive patients with MLBCL, eight male and 29 female (F/M ratio 1:3.5) with a median age of 35 years, were enrolled in the present study. Thirty-five (94.5%) patients presented disease confined to thorax, with chest symptoms of a rapidly enlarging mass in the mediastinum in 70% and superior vena cava syndrome (SCVS) in 43% of these patients. The first 10 patients received F-MACHOP and the succeeding 27 patients MACOP-B chemotherapy, associated in 24 (88.8%) with involved field radiation therapy (IFRT). 67Gallium scan was routinely performed pre- and post-IFRT in 18 patients. RESULTS: All 37 patients were assessable for response: 10 of 10 (100%) in the F-MACHOP and 26 of 27 (96.3%) in the MACOP-B group achieved overall responses (CR + PR). Three of 24 (12.5%) patients in PR after chemotherapy obtained CR after IFRT. Persistent Gallium avidity was observed in 16 patients after chemotherapy and in only four patients after IFRT. Thus far, four of the 10 F-MACHOP and two of the 26 MACOP-B responders have presented disease progression. The probability of progression-free survival (PFS) was 91% and 60% (P < 0.02) while overall survival (OS) was 93% and 70% (P = n.s.) at a mean follow-up of 27 and 52 months in the MACOP-B + IFRT and F-MACHOP groups, respectively. CONCLUSION: MACOP-B + IFRT has proved to be a highly effective and less toxic therapeutic approach for primary MLBCL and appears to be superior to other third-generation chemotherapy regimens.     

Endothelial cell analysis of corneas from donor eyes with an intraocular lens: a comparative study

OBJECTIVES: To examine the relationship between patient-reported depression and adherence to therapy with interferon beta-1b (IFN beta-1b) and to test the hypothesis that treatment of depression is associated with improved adherence. DESIGN: Patients with multiple sclerosis were followed up 6 months after initiating therapy with IFN beta-1b. SETTING: A university outpatient multiple sclerosis center, an academic group practice, and a health maintenance organization. PATIENTS: Eighty-five patients with clinically evident multiple sclerosis taking IFN beta-1b. MAIN OUTCOME MEASURE: Follow-up questionnaire. RESULTS: Thirty-five (41%) of the 85 patients reported new or increased depression within 6 months of initiating therapy with IFN beta-1b. Patients experiencing symptoms of depression were more likely to discontinue therapy. Among the patients reporting new or increased depression, 86% who received psychotherapy or antidepressant medication and 38% of the patients who received no therapy for depression continued the IFN beta-1b therapy (P = .003). Although psychotherapy was used as a treatment option more frequently in university and academic group practice-based multiple sclerosis clinics than in the health maintenance organization (P = .02), the treatment adherence patterns were similar across sites. CONCLUSIONS: These findings support previous findings that patients report increased depression after initiating therapy with IFN beta-1b. Although the source of this depression is unclear, these findings suggest that treating patient-reported depression increases adherence to treatment.     

Fluorouracil and leucovorin with or without interferon alfa-2b in advanced colorectal cancer: analysis of a prospective randomized phase III trial. Hellenic Cooperative Oncology Group

PURPOSE: To investigate if double modulation of fluorouracil (5-FU) with leucovorin (folinic acid [FA]) and interferon alfa-2b (IFN 2b) improves responses and survival in comparison to single modulation of 5-FU with FA. PATIENTS AND METHODS: One hundred six patients with histologically confirmed advanced colorectal cancer, measurable disease, and without previous chemotherapy were prospectively randomized into two groups. Patients in group A received 5-FU 450 mg/m2 as an intravenous bolus in the midinfusion of FA weekly. FA was given at a dose of 200 mg/m2 in 500 mL 0.9% normal saline solution in 2-hour infusion. Patients in group B received exactly the same regimen plus IFN 2b 5 million units subcutaneously three times weekly. RESULTS: All patients were well balanced in both groups regarding age, sex, performance status, number, and site of metastasis. One hundred two patients were assessable. All patients have died. There was no difference in response between the two groups (7.8% v 9.8%). Median survival was 10.1 months in group A, and 7.2 months in group B (P = .00189). Median time to progression was 8.4 and 5.2 months, respectively (P = .00196). Overall, better performance status and older age had a positive impact on survival. Toxicity was the most important and catastrophic aspect of this study. Patients who received IFN 2b had significantly worse anemia, neutropenia, diarrhea, anorexia, weight loss, flu-like syndrome, and psychological reactions. CONCLUSION: Based on this final analysis, the addition of IFN 2b to the combination of 5-FU and FA enhances toxicity and contributes to decreased survival.     

VACOP-B versus VACOP-B plus autologous bone marrow transplantation for advanced diffuse non-Hodgkin's lymphoma: results of a prospective randomized trial by the non-Hodgkin's Lymphoma Cooperative Study Group

PURPOSE: The aim of this multicenter randomized study was to compare conventional therapy with conventional plus high-dose therapy (HDT) and autologous bone marrow transplantation (ABMT) as front-line treatment for poor-prognosis non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Between October 1991 and June 1995, 124 patients, aged 15 to 60 years, with diffuse intermediate- to high-grade NHL (Working Formulation criteria), stages II bulky (> or = 10 cm), III, or IV were enrolled. Sixty-one patients were randomized to receive etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (VACOP-B) for 12 weeks and cisplatin, cytarabine, and dexamethasone (DHAP) as a salvage regimen (arm A), and 63 to receive VACOP-B for 12 weeks plus HDT and ABMT (Arm B). RESULTS: There was no significant difference in terms of complete remissions (CRS) in the two groups: 75% in arm A, and 73% in arm B. The median follow-up observation time was 42 months. The 6-year survival probability was 65% in both arms. There was no difference in disease-free survival (DFS) or progression-free survival (PFS) between the two groups. DFS was 60% and 80% (P = .1) and PFS was 48% and 60% (P = .4) for arms A and B, respectively. Procedure feasibility was the major problem. In arm B, 29% of enrolled patients did not undergo HDT and ABMT. A statistical improvement in terms of DFS (P = .008) and a favorable trend in terms of PFS (P = .08) for intermediate-/high- plus high-risk group patients assigned to HDT and ABMT was observed. CONCLUSION: In this study, conventional chemotherapy followed by HDT and ABMT as front-line therapy seems no more successful than conventional treatment in terms of overall results. However, our results suggest that controlled studies of HDT plus ABMT should be proposed for higher risk patients.     

Molecular characterization of thalassemias in the Valencia community and its relationship with the hematological phenotype

BACKGROUND: To explore the flow cytometric diagnosis of malignant lymphoma, we examined the deoxyribonucleic acid (DNA) ploidy, proliferative activities, and immunophenotype of surgical biopsy- and fine-needle aspiration (FNA)-derived materials. Our goal was to determine the possibility of making a diagnosis of malignant lymphoma by flow cytometric analysis of FNA-derived materials. METHODS: The DNA ploidy and proliferative indices including the percentage of S-phase fraction (SPF), G2 + M fraction (G2M), and Ki-67-positive fraction (Ki-67) were analyzed on the fresh materials from 84 consecutive patients with suspected malignant lymphoma. Flow cytometric analysis of surface antigens was simultaneously performed. Fourteen of the patients underwent FNA and subsequent surgical biopsy of the same lymph nodes for flow cytometric analysis. RESULTS: The proliferative indices of intermediate-grade non-Hodgkin's lymphomas (NHL) (n = 28) and high-grade NHL (n = 23) were significantly higher than those of the reactive hyperplasia (n = 25). The total for SPF + G2M of 6% was a satisfactory threshold for differentiating these NHL from reactive hyperplasia (sensitivity of 84%, specificity of 88%, and accuracy of 86%). However, low-grade NHL (n = 3) and Hodgkin's lymphoma (HL, n = 5) could not be discriminated by employing this parameter. DNA aneuploidy was seen in 13 of the 28 intermediate-grade NHL and 8 of the 23 high-grade NHL, whereas it was not seen in 25 reactive hyperplasia, 3 low-grade NHL, and 5 HL. The percentage of CD19-positive cells in B-cell NHL or CD3-positive cells in T-cell NHL was significantly higher compared with those for reactive hyperplasia. The percentage of CD16 + CD56-positive cells in natural killer (NK) cell NHL was extremely high, with a mean of 91.8%. Flow cytometric results for FNA-derived materials showed excellent correlation with those for surgical biopsy-derived specimens. CONCLUSIONS: Analyses of DNA ploidy, proliferative activities, and immunophenotype by flow cytometry (FCM) are useful for diagnosing intermediate- and high-grade NHL. Fine-needle aspiration is a less invasive approach than surgical biopsy, and, when combined with FCM, it may have a place in the diagnosis of NHL.     

非含铂双药和非含铂单药治疗老年和/或PS差的非小细胞肺癌病人疗效:荟萃分析

Objective:The aim of the study was to compare the efficacies and toxicities of non-platinum doublets (doublets group) with a non-platinum single agent (single-agent group) in previously untreated advanced non-small cell lung cancer (NSCLC) patients with elderly age and/or poor performance status (PS).Methods:The PubMed database was screened.Subsequently,the hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS),relative risks (RRs) for overall response rate (ORR) and one-year survival,and odds ratios (ORs) for the different types of toxicities were pooled using the Review Manager 5.0 package.Results:This study comprised of 1427 patients enrolled in four randomized controlled trials.The pooled HR showed that the doublet group could increase ORR (P = 0.002) with no heterogeneity (P = 0.64),and might improve OS (P = 0.01 / P = 0.06) with heterogeneity (P < 0.001).There was no significant difference in PFS (P = 0.16) and one-year survival (P = 0.25) between two treatment groups.The doublet group led to more grade 3/4 neutropenia and thrombocytopenia than the single-agent group (P = 0.02 and P = 0.000,respectively).The incidences of grade 3/4 anemia,vomiting,mucositis,constipation,diarrhea,neurotoxicity,allergy,and fatigue between the two treatment groups were insignificant.Conclusion:Except for neutropenia and thrombocytopenia,the non-platinum doublets could increase ORR,and might improve OS for NSCLC patients with elderly age and/or poor PS without addition of more side effects;however,the doublets showed an increased rate of neutropenia and thrombocytopenia.The addition of doublets may not improve PFS and one-year survival.     

Autologous stem cell transplantation (ASCT) for poor prognostic Hodgkin's disease (HD): comparative results with two CBV regimens and importance of disease status at transplant

Clinical outcome of 47 consecutive patients with advanced HD who underwent ASCT in our Department was analyzed retrospectively. Median age was 28 years (28 males and 19 females). At transplant, 15 (32%) patients were in CR (five in first CR after two chemotherapy regimens and 10 in second CR), eight (17%) in PR (seven without a prior CR), 22 (51%) had relapsing disease (19 with sensitive relapse) and two had primary refractory disease. The CVB regimen with two different schedules was used: 22 (47%) patients received standard CBV (CY 6 g/m2, BCNU 300 mg/m2 and etoposide 600 mg/m2) and 25 (53%) received an increased CBV dose (CY 7.2 g/m2, BCNU 440 mg/m2 and etoposide 2 g/m2). Antitumor response for 28 evaluable patients was similar for both CBV regimens: 87 and 75% (P=0.39). At 7.2 years, actuarial overall survival (OS), progression-free survival (PFS) and event-free survival (EFS) for the whole series were 51.7+/-8%, 34+/-9% and 28+/-8%, with a median follow-up for the surviving patients of 3 years (0.7-7.6). No differences in these survival functions according to the CBV regimen used were observed (P=0.57). A history of a prior CR (P=0.003), duration of first CR >1 year (P=0.04), absence of bulky nodal disease at transplant (P=0.054), absence of extranodal disease at transplant (P=0.01), and a CR status at transplant (P=0.0006) were associated with a better PFS on univariant analysis. On multivariate analysis, only CR status at transplant remained significant (P=0.05). When patients in second CR at transplant and those in first sensitive relapse were analyzed separately, no differences in clinical characteristics or in treatment received pretransplant were observed; however, PFS was significantly different (P=0.01). In conclusion, CR status at transplant is useful in identifying 'good risk' patients and is necessary to obtain the greatest benefit from ASCT independent of the CBV regimen used.     

Combination chemotherapy, glucocorticoids, and interferon alfa in the treatment of multiple myeloma: a Southwest Oncology Group study

PURPOSE: Standard therapy for multiple myeloma consists of cytotoxic chemotherapy plus glucocorticoids. Interferon (IFN) alfa maintenance is reported to prolong chemotherapy-induced remissions and survival. This study evaluates induction chemotherapy, glucocorticoids, and interferon maintenance in myeloma. PATIENTS AND METHODS: Five hundred twenty-two previously untreated myeloma patients were randomized to three chemotherapy regimens with differing glucocorticoid intensities. Patients who achieved remission were randomized to receive IFN or observation until relapse. Patients who failed to respond to chemotherapy received IFN alfa plus dexamethasone (DEX). RESULTS: Five hundred nine patients were eligible for induction chemotherapy. Chemotherapy with higher dose-intensity glucocorticoids yielded higher response rates and improved survival (P = .02 for the three-group comparison; P < .05 for each higher glucocorticoid arm v vincristine, melphalan, cyclophosphamide, and prednisone alternating with vincristine, carmustine [BCNU], doxorubicin, and prednisone [VMCP/VBAP]). One hundred ninety-three patients who achieved remission were randomized to receive IFN alfa 3 MU three times weekly or observation. IFN was not superior to observation for relapse-free (P = .95) or overall survival (P = .39) from start of maintenance. Eighty-eight induction failures received 5 MU of IFN three times weekly plus DEX. Patients who received IFN/DEX had a median survival duration of 48 months from start of IFN/DEX. CONCLUSION: Higher-dose glucocorticoids increases frequency of response to chemotherapy and prolong survival in myeloma. IFN maintenance with the dose schedule used in this trial did not prolong relapse-free or overall survival. We cannot exclude a small effect of IFN, as most individual trials do not have sufficient statistical power. Meta-analysis of randomized trials evaluating IFN maintenance in myeloma might be of value. While IFN appeared ineffective, addition of higher-dose glucocorticoids improved outcome in myeloma.     

Comparison of the effects of intralesional interferon alfa-2a, 2b and the combination of 2a and 2b in the treatment of basal cell carcinoma

Interferons (IFN), especially alfa-2a and 2b, are potent inhibitors of normal and malignant cell growth and effective choices in the treatment of basal cell carcinoma (BCC). The aim of the study was to evaluate the effectiveness of the IFN alfa-2a and 2b, and whether this effect may be increased by their combination. A total of 45 patients with histopathologically confirmed BCC were divided into three groups, equally. Groups 1,2 and 3 were treated with intralesional IFN alfa-2a, 2b, and the combination of 2a and 2b, respectively. Lesions were injected three times weekly in Groups 1 and 2 (total ten injections). IFN alfa-2a and 2b were injected alternately in Group 3 (5 IFN alfa-2a and 5 IFN alfa-2b). Eight weeks after completion of therapy, cytologic specimens were taken, and all cases were evaluated clinically and cytologically. Ten (66.6%) patients had a complete response (CR) and 5 (33.3%) had a partial response (PR) in Group 1. Patients in Group 2 showed 10 (66.6%) CR, 4 (26.6%) PR, and 1 (6.6%) non response. In Group 3, 11 (73.3%) patients had CR and 4 (26.6%) had PR. Follow-up periods ranged from 6-24 months, and no recurrences have been observed. These results suggest that IFN alfa-2a, 2b, and the combination of 2a and 2b appear to be effective choices for the treatment of BCC; the effectiveness is not increased by their combination.     

Frequency and significance of anemia in non-Hodgkin's lymphoma patients

OBJECTIVES: Retrospective evaluation of anemia frequency and its prognostic value in patients with different subtypes of non-Hodgkin's lymphoma and comparison with other clinical characteristics. PATIENTS AND METHODS: Anemia was defined as a hemoglobin value less than or equal to 12 g/dl for all men and women over 50 years of age, and less than or equal to 11 g/dl for women under 50 years of age. The study included 1077 adult lymphoma patients treated between 1980 and 1995 with the following histologic subtypes: 127 patients with small lymphocytic or lymphoplasmacytoid, 62 with marginal zone, 50 with mantle-cell, 208 with follicular, 104 with T-cell lymphoma, 426 with diffuse large-cell and, finally, 73 patients with other high-grade lymphomas. RESULTS: Anemia was present in 341 patients (32%). It was an adverse prognostic factor (P < 0.0001) for overall survival (OS) and progression-free survival (PFS) but not for relapse-free survival (RFS). When patients with and those without bone marrow involvement were considered separately, anemia remained an adverse factor. Anemia was significantly associated with shorter PFS in small lymphocytic or lymphoplasmacytoid, mantle cell, diffuse large cell and high-grade lymphomas and with shorter OS in all histologic subgroups except marginal zone lymphoma. In multivariate analysis, anemia was a significant prognostic factor for OS and PFS for the population as a whole (P = 0.0001 and P = 0.0048, respectively) and in patients with bone marrow involvement (P = 0.007 and P = 0.005, respectively) but not in patients without bone marrow involvement. Finally, the addition of anemia to the International Prognostic Index led to an improvement for OS (P = 0.0004) and PFS (P = 0.0004). CONCLUSIONS: Anemia is an important adverse prognostic factor for the outcome of lymphoma patients, particularly in some histologic subgroups and in patients with bone marrow involvement.     

Adjuvant 5-fluorouracil and leucovorin with or without interferon alfa-2a in colon carcinoma: National Surgical Adjuvant Breast and Bowel Project protocol C-05

BACKGROUND: National Surgical Adjuvant Breast and Bowel Project (NSABP) protocol C-03 showed a benefit from leucovorin (LV)-modulated 5-fluorouracil (5-FU) adjuvant therapy (5-FU + LV) in patients with Dukes' stage B or C carcinoma of the colon. Preclinical and clinical phase I/II data suggested that interferon alfa-2a (IFN) enhanced the efficacy of 5-FU therapy. Accordingly, in NSABP protocol C-05, the addition of recombinant IFN to 5-FU + LV adjuvant therapy was evaluated. METHODS: Data are presented for 2176 patients with Dukes' stage B or C cancer entered onto protocol C-05 during the period from October 1991 through February 1994. Individuals with an Eastern Cooperative Oncology Group performance status of 0-2 (ranges from fully active to ambulatory and capable of self-care but unable to work), a life expectancy of at least 10 years, and curative resection were stratified by sex, disease stage, and number of involved lymph nodes and were randomly assigned to receive either 5-FU + LV or 5-FU + LV + IFN; the mean time on the study as of June 30, 1997, was 54 months. All statistical tests were two-sided. RESULTS: There was no statistically significant difference in either disease-free survival (5-FU + LV, 69%; 5-FU + LV + IFN, 70%) or overall survival (5-FU + LV, 80%; 5-FU + LV + IFN, 81%) at 4 years of follow-up. Toxic effects of grade 3 or higher were observed in 61.8% of subjects in the group treated with 5-FU + LV and in 72.1% of subjects in the group treated with 5-FU + LV + IFN; fewer patients in the latter group completed protocol-mandated 5-FU + LV therapy than in the former group (77.1% versus 88.5%). CONCLUSION: The addition of IFN to 5-FU + LV adjuvant therapy confers no statistically significant benefit, but it does increase toxicity.     

A radioreceptor assay for mass measurement of inositol (1,4,5)-trisphosphate using saponin-permeabilized outdated human platelets

PURPOSE: To evaluate the therapeutic efficacy of moderate-dose total abdominopelvic irradiation (TAI) in a retrospective series of pretreated non-Hodgkin's lymphomas (NHL). METHODS AND MATERIALS: From 1977 to 1994, 45 patients received TAI after failure of chemotherapy (CT). According to the Working Formulation, 10 patients were diagnosed with class A (group I), 19 with class B, C, or D (follicular) (group II), and 16 with class E or more severe (group III) NHL. Irradiation consisted of two daily fractions of 0.80 Gy each for a total dose of 20 Gy. RESULTS: Mean follow-up after TAI was 102 months (range 8-156). For the entire group, the complete response (CR) rate was 66%, the partial response (PR) rate 29%, 10-year overall survival (OS) 35%, 10-year disease-free survival (DFS) 29%, and median survival 32 months. When results between subgroups were compared, CR was 70% in group I, 84% in group II, and 44% in group III; and survival was statistically higher in group II than in groups I and III: 10-year OS 52% vs. 10% (p < 0.01) and 31% (p < 0.05), respectively, 10-year DFS 37% vs. 10% (p < 0.03) and 19% (p < 0.05), respectively. Grade III or IV complications were gastrointestinal in 27% of patients and hematologic in 25%. CONCLUSION: Large-field irradiation in moderate doses could provide an alternative to bone marrow transplantation in refractory NHL, especially in cases showing a follicular growth pattern.
