RESUMO

BACKGROUND: The purpose of the protocol was to reduce the treatment burden in clinical stage I (CSI) seminoma by offering risk-adapted treatment. The protocol aimed to prospectively validate the proposed risk factors for relapse, stromal invasion of the rete testis and tumor diameter >4 cm, and to evaluate the efficacy of one course of adjuvant carboplatin. PATIENTS AND METHODS: From 2007 to 2010, 897 patients were included in a prospective, population-based, risk-adapted treatment protocol implementing one course of adjuvant carboplatin AUC7 (n = 469) or surveillance (n = 422). In addition, results from 221 patients receiving carboplatin between 2004 and 2007 are reported. RESULTS: At a median follow-up of 5.6 years, 69 relapses have occurred. Stromal invasion of the rete testis [hazard ratio (HR) 1.9, P = 0.011] and tumor diameter >4 cm (HR 2.7, P < 0.001) were identified as risk factors predicting relapse. In patients without risk factors, the relapse rate (RR) was 4.0% for patients managed by surveillance and 2.2% in patients receiving adjuvant carboplatin. In patients with one or two risk factors, the RR was 15.5% in patients managed by surveillance and 9.3% in patients receiving adjuvant carboplatin. We found no increased RR in patients receiving carboplatin <7 × AUC compared with that in patients receiving ≥7 × AUC. CONCLUSION: Stromal invasion in the rete testis and tumor diameter >4 cm are risk factors for relapse in CSI seminoma. Patients without risk factors have a low RR and adjuvant therapy is not justified in these patients. The efficacy of adjuvant carboplatin is relatively low and there is need to explore more effective adjuvant treatment options in patients with high-risk seminoma. The data do not support the concept of a steep dose response for adjuvant carboplatin.

RESUMO

BACKGROUND: SWENOTECA has since 1998 offered patients with clinical stage I (CS I) nonseminoma, adjuvant chemotherapy with one course of bleomycin, etoposide and cisplatin (BEP). The aim has been to reduce the risk of relapse, sparing patients the need of toxic salvage treatment. Initial results on 312 patients treated with one course of adjuvant BEP, with a median follow-up of 4.5 years, have been previously published. We now report mature and expanded results. PATIENTS AND METHODS: In a prospective, binational, population-based risk-adapted treatment protocol, 517 Norwegian and Swedish patients with CS I nonseminoma received one course of adjuvant BEP. Patients with lymphovascular invasion (LVI) in the primary testicular tumor were recommended one course of adjuvant BEP. Patients without LVI could choose between surveillance and one course of adjuvant BEP. Data for patients receiving one course of BEP are presented in this study. RESULTS: At a median follow-up of 7.9 years, 12 relapses have occurred, all with IGCCC good prognosis. The latest relapse occurred 3.3 years after adjuvant treatment. The relapse rate at 5 years was 3.2% for patients with LVI and 1.6% for patients without LVI. Five-year cause-specific survival was 100%. CONCLUSIONS: The updated and expanded results confirm a low relapse rate following one course of adjuvant BEP in CS I nonseminoma. One course of adjuvant BEP should be considered a standard treatment in CS I nonseminoma with LVI. For patients with CS I nonseminoma without LVI, one course of adjuvant BEP is also a treatment option.

RESUMO

Azoospermia is a serious potential side effect following treatment for testicular cancer (TC). Our purpose was to examine possible predictors of long-term azoospermia in TC survivors. Ejaculates and blood samples were obtained from 217 patients at post-orchidectomy but before further treatment (T0 ) and/or at one or more of the time points 6, 12, 24, 36-60 months after treatment (T6 , T12 , T24 , T36-60 ). All patients delivered ejaculates at T36-60 , of which 117 also had confirmed presence of spermatozoa in the ejaculate at T0 , enabling longitudinal analyses. Types of therapy, cryptorchidism and Inhibin B before and after treatment were evaluated in relation to risk of azoospermia at T36 . Inhibin B levels at T6 , T12 and T24 were predictors of azoospermia at T36 with cut-off levels at 49.7, 55.9 and 97.8 ng/L respectively (sensitivity 100%, specificity 57-78%). The frequency of azoospermia in all patients at T36-60 was 7.8% (95% CI 4.9-12%). As compared to surveillance patients, only those receiving >4 cycles of chemotherapy or ≥4 cycles of chemotherapy + radiotherapy (RT) had increased risk of long-term azoospermia (63% vs. 4.4% in the surveillance group; p = 0.0018). In conclusion, all patients with sperm production at post-orchidectomy but before further treatment and Inhibin B >56 ng/L 12 months after treatment had sperm production 3 years post-treatment. Eight per cent of TC survivors had azoospermia 3-5 years post-treatment, with highest risk in those receiving >4 cycles of chemotherapy or ≥4 cycles of chemotherapy in combination with RT.

RESUMO

In November 2011, the Third European Consensus Conference on Diagnosis and Treatment of Germ-Cell Cancer (GCC) was held in Berlin, Germany. This third conference followed similar meetings in 2003 (Essen, Germany) and 2006 (Amsterdam, The Netherlands) [Schmoll H-J, Souchon R, Krege S et al. European consensus on diagnosis and treatment of germ-cell cancer: a report of the European Germ-Cell Cancer Consensus Group (EGCCCG). Ann Oncol 2004; 15: 1377-1399; Krege S, Beyer J, Souchon R et al. European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part I. Eur Urol 2008; 53: 478-496; Krege S, Beyer J, Souchon R et al. European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part II. Eur Urol 2008; 53: 497-513]. A panel of 56 of 60 invited GCC experts from all across Europe discussed all aspects on diagnosis and treatment of GCC, with a particular focus on acute and late toxic effects as well as on survivorship issues. The panel consisted of oncologists, urologic surgeons, radiooncologists, pathologists and basic scientists, who are all actively involved in care of GCC patients. Panelists were chosen based on the publication activity in recent years. Before the meeting, panelists were asked to review the literature published since 2006 in 20 major areas concerning all aspects of diagnosis, treatment and follow-up of GCC patients, and to prepare an updated version of the previous recommendations to be discussed at the conference. In addition, ∼50 E-vote questions were drafted and presented at the conference to address the most controversial areas for a poll of expert opinions. Here, we present the main recommendations and controversies of this meeting. The votes of the panelists are added as online supplements.

RESUMO

BACKGROUND: To describe incidence, risk factors, and influence of treatment on occurrence of central nervous system (CNS) relapse or progression in younger patients with aggressive B-cell lymphoma. PATIENTS AND METHODS: We analyzed 2210 patients with aggressive B-cell lymphoma treated on various studies for CNS relapse/progression. Treatment consisted of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) ± etoposide. Six hundred and twenty patients also received rituximab. CNS prophylaxis was intrathecal methotrexate on High-CHOEP and MegaCHOEP phase III studies if upper neck, head, bone marrow, or testes were involved. RESULTS: Fifty-six of 2196 patients (2.6%) developed CNS disease. It occurred early (median 7.0 months), median survival was 5.0 months. Patients with age-adjusted International Prognostic Index (aaIPI) 0 or 1 treated with rituximab showed a low risk for CNS disease (2-year rates: 0% or 0.5%), and rituximab decreased the risk (relative risk 0.3, 95% confidence interval 0.1-0.9, P = 0.029). Patients with aaIPI 2 or 3 showed a moderate risk (4.2%-9.7%) and no significant reduction of CNS disease with rituximab. CNS prophylaxis was of no significant benefit. CONCLUSIONS: In younger patients with aaIPI 0 or 1, CNS relapse/progression is very rare; in patients with aaIPI 2 or 3, the risk is higher (up to 10%) and requires new diagnostic strategies and treatment.

RESUMO

Childhood cancer survivors (CCS) have an increased risk of impaired spermatogenesis, but data regarding the disease- and treatment-related risk factors of azoospermia are scarce. Such information is crucial both for counselling CCS and for selecting patients for testicular tissue cryopreservation. The proportion of azoospermic men in CCS was 18% [95% confidence interval (CI): 12-26], specifically for leukaemias (19%; 95% CI: 5.5-42), Hodgkin's disease (53%; 95% CI: 29-76), non-Hodgkin's lymphoma (11%; 95% CI: 0.28-48) and testicular cancer (11%; 95% CI: 0.28-48). In CCS treated with high doses of alkylating agents, the proportion of azoospermic men was 80% (95% CI: 28-99) and if radiotherapy was used additionally, the proportion was 64% (95% CI: 35-87). In CCS with subnormal Inhibin B levels, the proportion of azoospermic men was 66% (95% CI: 47-81) and for those with elevated follicle-stimulating hormone (FSH) levels, the proportion was 50% (95% CI: 35-67). Among CCS with subnormal testicular volume (≤ 24 mL), azoospermia was found in 61% (95% CI: 39-80) of the cases. Most childhood cancer diagnoses are associated with an increased risk of azoospermia, especially in CCS receiving testicular irradiation, high doses of alkylating drugs and other types of cytotoxic treatment, if combined with irradiation. Inhibin B, FSH and testicular volume can be used as predictors for the risk of azoospermia.

RESUMO

Few data illustrate the man's reaction to orchidectomy. We investigated long-lasting feelings of loss and uneasiness or shame about the body after removal of a testicle by orchidectomy. We identified 1173 eligible men diagnosed with non-seminomatous testicular cancer treated according to the national cancer-care programmes Swedish-Norwegian Testicular Cancer Group I-IV between 1981 and 2004. We asked the survivors about feelings of loss and uneasiness or shame after having had a testicle removed by orchidectomy. We obtained information from 960 (82%) testicular cancer survivors. We found that 32% of these men miss or previously missed their removed testicle(s) and that 26% have or previously had feelings of uneasiness or shame about their body because of the removed testicle(s). Men who had never been offered a prosthesis reported feelings of loss [relative risk (RR): 2.0; 95% confidence interval (CI): 1.3-3.0] and uneasiness or shame (RR: 2.0; 95% CI: 1.3-3.2) to a higher extent than those who had been offered, but rejected a prosthesis. An orchidectomy may result in long-lasting feelings of loss and uneasiness or shame in some men; offering a testicular prosthesis may hinder this experience.

RESUMO

BACKGROUND: To offer minimized risk-adapted adjuvant treatment on a community and nationwide basis for patients with clinical stage 1 (CS1) nonseminomatous germ-cell testicular cancer (NSGCT). The aim was to reduce the risk of relapse and thereby reducing the need of later salvage chemotherapy while maintaining a high cure rate. PATIENTS AND METHODS: From July 1995 to January 1998, a total of 232 Swedish and Norwegian patients were treated for CS1 NSGCT. All were eligible for inclusion into one of two community-based multicenter Swedish and Norwegian Testicular Cancer Project (SWENOTECA) III studies. One study was a prospective randomized study for patients without vascular invasion in the testicular tumor (VASC-), evaluating the effect of one adjuvant course of cisplatin, vinblastine and bleomycin (CVB) compared with surveillance. The second study was a prospective study evaluating the effect of two adjuvant courses of CVB for VASC+ patients. RESULTS: Due to slow accrual and emerging data on toxicity of CVB, the studies were prematurely closed for inclusion in 1998. Of the 232 CS1 patients treated during the study period, only 97 were included in the studies. As all remaining patients were managed according to the SWENOTECA III protocol, although not randomized, the data were pooled. At a median follow-up of 10.1 years, there have been 24 relapses. While one course of CVB to VASC- patients had limited effect on the relapse rate, two courses of adjuvant CVB reduced the relapse rate among VASC+ patients by >90%. Toxicity was high in patients administered adjuvant CVB as 24% of patients experienced grade 3 or 4 obstipation/ileus and 23% grade 3 or 4 infection. CONCLUSIONS: There was no statistical difference in relapse rate between one course of adjuvant CVB and surveillance for VASC- NSGCT patients. Two courses of adjuvant CVB for VASC+ NSGCT patients reduced the relapse rate with >90% in comparison to the surveillance group. Toxicity was unacceptably high for all patients receiving CVB. Adjuvant CVB chemotherapy has no place in the treatment of CS1 NSGCT.

RESUMO

As oncological treatment might impair the patients' fertility, male cancer patients are offered to cryopreserve semen prior to treatment. Impaired sperm DNA quality is associated with reduced fertility, and in case of assisted reproduction, sperm DNA integrity may have an impact on choice of method. Therefore, we have assessed sperm DNA integrity in cancer patients, comparing pre- and post-treatment quality. Sperm DNA integrity was investigated in cryopreserved semen from 121 cancer patients, the predominating diagnoses were germ cell cancer (GCC) and Hodgkin's lymphoma (HL). Post-treatment samples, with a median follow-up of 3 years, were analysed for 58 of the men, allowing a pre- and post-treatment analysis on an individual basis. Sperm DNA integrity was assessed using the Sperm Chromatin Structure Assay and expressed here as the DNA Fragmentation Index (DFI%). One hundred and thirty-seven fertile men served as controls. Before treatment, GCC (n = 84) and HL (n = 18) patients had higher DFI% than controls (n = 143) with a mean difference of 7.7 (95% CI 3.2-8.8) and 7.0 (95% CI 2-12), respectively. The same trend was observed for other cancer diagnoses, but without reaching statistical significance (mean difference 3.6, 95% CI -1.2 to 8.4). No increase was seen in DFI% comparing pre- and post-treatment semen, regardless of treatment modality. A moderate elevation of DFI% was observed in cryopreserved semen from cancer patients. Oncological treatment, generally, did not induce any increase in DFI. These findings should be considered when discussing the utilization of pre-treatment cryopreserved semen vs. post-treatment fresh sperm in cancer patients undergoing assisted reproduction.

RESUMO

BACKGROUND: Secondary central nervous system (CNS) involvement by aggressive lymphoma is a well-known and dreadful clinical complication. The incidence and risk factors for CNS manifestation were studied in a large cohort of elderly (>60 years) patients with aggressive lymphoma. PATIENTS AND METHODS: In all, 444 previously untreated patients were randomized to receive 3-weekly combination chemotherapy with cyclophosphamide, doxorubicin, vincristine and prednisone or cyclophosphamide, mitoxantrone, vincristine and prednisone (CNOP) (doxorubicin substituted by mitoxantrone) chemotherapy with or without filgrastim. Prophylactic intrathecal methotrexate was given to patients with lymphoma involvement of bone marrow, testis and CNS near sites. RESULTS: In all 29 of 444 (6.5%) developed CNS disease after a median observation time of 115 months. CNS was the only site of progression/relapse in 13 patients while part of a systemic disease manifestation in 16 patients. In univariate risk factor analysis, CNS occurrence was associated with extranodal involvement of testis (P = 0.002), advanced clinical stage (P = 0.005) and increased age-adjusted International Prognostic Index score (aaIPI; P = 0.035). In multivariate analysis, initial involvement of testis remained significant and clinical stage was of borderline significance. The median survival time was 2 months after presentation of CNS disease. CONCLUSION: A significant proportion of elderly patients with advanced aggressive lymphoma will develop CNS disease. CNS occurrence is related to testis involvement, advanced clinical stage and high aaIPI and the prognosis is dismal.

RESUMO

BACKGROUND: We evaluated the impact of testicular germ cell cancer (TGCC), its treatment and length of follow-up on sperm DNA integrity. METHODS: In 96 TGCC patients, semen was collected at specific intervals until 5 years after treatment. Sperm DNA integrity was assessed by the sperm chromatin structure assay (SCSA, n = 193) and by the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labelling (TUNEL, n = 159) assay. Results were expressed as DNA fragmentation index (DFI). Controls comprised of 278 military conscripts. RESULTS: Post-surgery testicular cancer (TC) patients did not differ from controls. Compared with pretreatment values, radiotherapy induced a transient increase in SCSA(DFI) (medians: 12 versus 19%; P = 0.03), normalizing after 3-5 years. One year or more after therapy, 5/13 (38%) of normozoospermic, irradiated patients had SCSA(DFI) >27% compared with 7% of normozoospermic controls (P = 0.002). More than two cycles of chemotherapy decreased DFI 3-5 years post-therapy (median SCSA(DFI): 12 versus 9.1%, P = 0.02; median TUNEL(DFI): 11 versus 7.5%, P = 0.03). CONCLUSION: Irradiation increases sperm DNA damage 1-2 years after treatment, and 38% of irradiated patients with normozoospermia had high (>27%) DNA damage, which may affect the sperm-fertilizing ability. TC per se is not associated with an increase of DFI, and DFI is reduced by three or more cycles of chemotherapy.

RESUMO

The purpose of this study was to investigate the prognostic effects of four biological markers, BCL2, TP53, Ki-67, and P-glycoprotein, and their possible clinical relevance in addition to the international prognostic index (IPI) in diffuse large B-cell lymphoma (DLBCL). A total of 405 patients with aggressive lymphoma, stage II-IV, between 18 and 67 years, were randomized in a trial comparing CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) with MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin). Of these, 267 cases were classified as DLBCL, with adequate paraffin blocks available in 207 cases, enabling immunohistochemical assessment of the expression of BCL2, TP53, P-glycoprotein, and Ki-67. In a multivariate analysis, stratified for IPI, high BCL2 expression (>10%) low (<60%) expression of Ki-67, and high TP53 protein expression (>75%) were shown to provide additional prognostic information with regard to overall or failure-free survival. We found no association between expression of P-glycoprotein and outcome. Assessment of BCL2 positivity might be introduced as part of the routine investigation in patients with DLBCL, but further studies are necessary to confirm the clinical relevance of Ki-67 and TP53 expression.

RESUMO

BACKGROUND: Testicular cancer (TC) patients have a high survival rate, and the question of post-therapy recovery of sperm production and its dependence on genetic predisposition is of major interest. METHODS: Ejaculates were obtained from 112 TC patients at one or more of the following time points: post-orchidectomy, or 6, 12, 24, 36 and 60 months post-therapy. The lengths of the androgen receptor (AR) function modulating CAG and GGN repeats in leukocyte DNA were also analysed. RESULTS: No significant decrease in sperm concentration was seen in men who received 1-2 cycles of adjuvant chemotherapy (ACT). Radiotherapy (RT) or more than two cycles of chemotherapy (HCT) caused an initial decline in sperm concentration, which returned to pre-treatment levels 2-5 years after therapy. In the HCT group, sperm concentration 12-24 months post-treatment (T(12-24)) was inversely correlated with CAG length (rho = -0.72, P = 0.03). The type of treatment, but not the concentration at T(0), was an independent predictor of sperm concentration at T(6) (P < 0.0005) and T(12-24) (P = 0.004). CONCLUSION: ACT did not induce a significant decline in sperm concentration. After HCT and RT, a significant reduction of sperm concentration was observed, recovering to pre-treatment levels 2-5 years post-treatment. In HCT-treated patients, the AR CAG length influenced the recovery of spermatogenesis.

RESUMO

The purpose of this study was to investigate the prognostic implications of BCL6 rearrangement in a uniformly treated population of patients with diffuse large B-cell lymphoma (DLBCL) and to characterise the relationship between BCL6 rearrangement and prognostic factors. A total of 269 patients with DLBCL entered a randomised trial comparing the chemotherapy regimen CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) to the MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, bleomycin) regimen. In 44 cases, frozen tissue was available for assessment of BCL6 status by Southern blot analysis. BCL6 was rearranged in six of 43 evaluable cases (14%), and was associated with elevated lactate dehydrogenase (LDH), and a higher patient age. No association between BCL6 status and expression of BCL2, Ki-67 or TP53 was found. Patients presenting with BCL6 rearrangement displayed a weak trend towards better overall and failure-free survival (67 and 67% at 5 years), compared to patients with germline BCL6 (63 and 52%), but the difference was not statistically significant. In accordance with previously published series, the presence of BCL6 rearrangement does not define a prognostically distinct subgroup of DLBCL. Assessment of BCL6 status may, however, be of clinical interest when related to other prognostic variables.

RESUMO

Estimation of complete response (CR) and partial response (PR) in patients with non-Hodgkin's lymphoma (NHL) is associated with a number of potential sources of error. The aim of this study was to define the reproducibility of response evaluation performed by an independent review committee (RC). In a phase III study of patients >60 yr with aggressive NHL, 60 patients who were already evaluated by the independent review committee (RC 1) for response were randomized to three groups and re-evaluated (RC 2). The assessment was classified into one of seven mutually exclusive categories, where the important borderlines with regard to one of the major end-points of the study, the CR rate, were between CR, "CR uncertain" (CR(U)), and PR. A discrepancy between RC 1 and 2 was found in 8/60 patients (13.3%), influencing the CR/CR(U) status in four of these patients. Two CR and two PR patients were reclassified as CR(U). Thus, CR/CR(U) was changed in 4/60 (6.7%). The reports of the local investigators were compared with that of RC 1 in 254 patients. The CR/CR(U) status was affected in 41 of these patients (16.1%). It is concluded that an independent RC is a major prerequisite for a uniform response evaluation in phase III clinical trials. However, the good RC reproducibility does not motivate a second assessment. Moreover, in the phase III setting end-points other than the CR rate, such as time to treatment failure, cause specific and overall survival are preferred.

RESUMO

This study was conducted to explore treatment and disease-related effects on health-related quality of life (HRQoL) in patients with aggressive lymphoma, to identify predictors for impaired long-term HRQoL, and to analyze the prognostic value of pretreatment HRQoL. Ninety-five patients with aggressive lymphoma, constituting a subset of a randomized multicenter trial comparing CHOP and MACOP-B, entered a HRQoL study, using the EORTC QLQ-C30 questionnaire. Patient scores were compared to scores from an age- and gender-adjusted reference population sample, and evaluation of the prognostic value of pretreatment QoL scores in relation to clinical prognostic factors was performed. Before treatment, patients exhibited lower scores of global QoL, physical, role, and social functions, and more appetite loss, compared to the reference population. Role functioning improved compared to baseline, but remained depressed compared to the reference group more than 8 mo after end of treatment. By then, the patient group displayed no difference in other HRQoL variables compared to that of the reference population. No reliable predictor for impaired long-term HRQoL could be identified. In multivariate analysis, including the factors of the International Prognostic Index, pretreatment global QoL was an independent prognostic marker for overall survival. In conclusion, in this population with aggressive lymphoma and favorable prognostic features, HRQoL was not substantially affected during the first year after diagnosis. Pretreatment global QoL may constitute a significant prognostic factor, meriting further investigation in prospective studies.

RESUMO

BACKGROUND: Insofar as a majority of children with malignant diseases are cured, the late effects of treatment are of major importance. PROCEDURE: A retrospective study was conducted of gonadal and sexual function of 77 adult male survivors of childhood malignancies treated and cured at a single center from 1970 to 1989 and followed for a median of 13 years. The study included an interview, physical examination, sperm test, and hormonal analyses. RESULTS: One-third of the patients were treated for hematological malignancies, one-third for CNS tumors, and one-third for other malignancies. Eleven patients required androgen substitution after treatment for tumors of the pituitary-hypothalamic region or acute lymphoblastic leukemia including testicular irradiation and/or orchiectomy. In three patients the testicles were removed. The other eight had small testicles, and those providing sperm samples had azoospermia, and sexual function was disturbed in most of them. Most of the remaining 66 patients had small testicles. Normozoospermia was found in 63%, oligozoospermia in 20%, and azoospermia in 17%. Although there was a highly significant correlation between testicular volume and sperm test, 25% of patients with testicles of <10 ml had normozoospermia. Sexual function was normal in 46 patients, and they were married at a frequency comparable to the normal population. Twenty-one patients had no signs of gonadal dysfunction. CONCLUSIONS: Patients treated for tumors in the hypothalamic-pituitary region or treated with testicular irradiation or with high doses of alkylating agents had severe gonadal and sexual dysfunction. Most of the other patients had good prospects for preserved gonadal and sexual function.

RESUMO

BACKGROUND: The long-term survival of patients with advanced stage aggressive lymphoma has not improved significantly during the last twenty years. In a randomised trial, the efficacy of MACOP-B, a six-drug weekly chemotherapy regimen, was compared to CHOP, the current standard regimen, in terms of overall and failure-free survival, toxicity and health related quality of life. PATIENTS AND METHODS: Four hundred five patients with aggressive lymphoma, stage II-IV, age 18-67, were randomised to receive either 12 weeks of MACOP-B or 8 courses of CHOP over 24 weeks. Special emphasis was put in the definition of Ann Arbor stage in extranodal disease. A subset of 95 patients also entered a quality of life study, based on the EORTC QLQ-C30. RESULTS: Thirty-one patients were ineligible. Among the remaining 374 patients, the median age was 52 years. According to the age-adjusted International Prognostic Index, 37% were 'high-intermediate' or 'high-risk' patients. No difference could be demonstrated, either in overall survival (60% at five years in the MACOP-B group and 59% in the CHOP group) or in failure-free survival (47% at five years with MACOP-B and 44% with CHOP). In terms of quality of life, physical function and global quality of life were more impaired in patients receiving MACOP-B, who also exhibited more non-haematological toxicity. CONCLUSION: No superiority of MACOP-B compared to CHOP could be demonstrated. CHOP remains the treatment of choice in low-risk patients. At present, intensified or experimental treatment should be reserved for high-risk disease.

RESUMO

Experience in using rapidly internalizing antibodies, such as the anti-CD22 antibody, for radioimmunotherapy of B-cell lymphomas is still limited. The present study was conducted to assess the efficacy and toxicity of a 131I-labeled anti-CD22 monoclonal antibody (mAb), LL2, in patients with B-cell lymphomas failing first- or second-line chemotherapy. Eligible patients were required to have measurable disease, less than 25% B cells in unseparated bone marrow, and an uptake of 99mTc-labeled LL2Fab' in at least one lymphoma lesion on immunoscintigram. Eight of nine patients examined with immunoscintigraphy were unequivocally found to have an uptake, and therapy with 131I-labeled anti-CD22 [1330 MBq/m2 (36 mCi/m2)] preceded by 20 mg of naked anti-CD22 mAb was administered. Three patients achieved partial remission (duration, 12, 3, and 2 months), and one patient with progressive lymphoma showed stable disease for 17 months. Four patients exhibited progressive disease. The toxicity was hematological. Patients with subnormal counts of neutrophils or platelets before therapy seemed to be more at risk for hematological side effects. Radioimmunotherapy in patients with B-cell lymphomas using 131I-labeled mouse anti-CD22 can induce objective remission in patients with aggressive as well as indolent lymphomas who have failed prior chemotherapy.

RESUMO

A single institution series of 81 consecutive, cytogenetically analyzed, diffuse large B-cell lymphomas (DLBL), the majority of which treated with anthracycline-containing combination chemotherapy, were reviewed retrospectively to investigate whether the karyotypic pattern or certain abnormalities correlate with survival. Clonal chromosome changes were found in 79 of the 81 cases. The prognostic impact of the following aberrations, all suggested in previous studies to be associated with either shorter or longer survival, were tested: 1q21-23 breakpoints, +2/dup(2p), +3/dup(3p), +5, +6, 6q21-25 breakpoints, monosomy 7/der(7p)/i(7q), trisomy 7, 14q11-12 breakpoints, monosomy 17/der(17p)/i(17q), trisomy 18, > 4 marker chromosomes, > 4 breakpoints, and > or = 10 abnormalities. Univariate analysis showed that a breakpoint at 1q21-23 or trisomy 6 was associated with a shorter survival. However, when adjusted for age, stage, performance status and lactate dehydrogenase level, none of the cytogenetic aberrations had an independent prognostic value. Thus, the present investigation provides no support for any of the above-mentioned abnormalities being of prognostic importance in DLBL.
