Abstract
Early detection of relapse has been advocated to improve survival in children with recurrent medulloblastoma. However, the prognostic factors and the longer term outcome of these patients remains unclear. Pattern of recurrences were analysed in three consecutive protocols of the Société Française d'Oncologie Pédiatrique (1985-91). A uniform surveillance programme including repeated lumbar puncture combined with computerized tomography (CT) or magnetic resonance imaging (MRI) scan was applied for all registered patients. Forty-six out of 116 patients had progressive or recurrent disease. The median time from diagnosis to recurrence was 10.5 months and 76% relapses occurred during the first 2 years. Seventeen patients had asymptomatic relapses that were detected by the surveillance protocol. Forty-one patients were treated at time of progression. Twenty-three responded to salvage therapy and 11 achieved a second complete remission. The median survival time after progression was 5 months (<1-41 months), and only two patients remained alive at time of follow-up. Length of survival is primarily related to some specific patterns of relapse (time from diagnosis to recurrence, circumstances of relapse, extent of relapse) and to the response to salvage therapy. No evidence of long-term benefit appeared from any form of treatment.

Abstract
PURPOSE The impact of treatment options on survival and late neurologic toxicity was investigated in a series of patients with primary cerebral lymphoma (PCL) and no known cause of immunosuppression. PATIENTS AND METHODS Prognostic factors for survival and treatment-induced late neurotoxicity were investigated in a retrospective series of 226 patients with PCL. RESULTS With a median follow-up of 76 months, the median overall survival was 16 months and 5-year survival was 19%. In a univariate analysis, age greater than 60 years, performance status, CSF protein level greater than 0.6 g/L, involvement of corpus callosum or subcortical grey structures, detectable lymphoma cells in CSF, increased serum lactate dehydrogenase (LDH), but not histological subtype, were significantly correlated with a poor survival. Treatment with chemotherapy versus radiotherapy alone (P = .05), high-dose methotrexate (HDMTX; P = .0007), and cytarabine (P = .04) correlated with a better survival in univariate analysis. Using the Cox model, age, performance status, and CSF protein were independently correlated with survival. After adjustment of these factors, treatment with an HDMTX-containing regimen remained the only treatment-related factor independently correlated with survival (P = .01). The projected incidence of treatment-induced late neurotoxicity was 26% at 6 years in this series, with a median survival from the diagnosis of late neurotoxicity of 12 months. Treatment with radiotherapy followed by chemotherapy was the only parameter correlated with late neurotoxicity in multivariate analysis (relative risk, 11.5; P = .0007). CONCLUSION Patients with PCL treated with regimens that included HDMTX followed by radiotherapy have an improved survival, but not a higher risk of late neurotoxicity as compared with other treatment modalities in this series.

Abstract
PURPOSE AND METHODS Optimization of remission-induction and postremission therapy in elderly individuals with acute myeloid leukemia (AML) was the subject of a randomized study in patients older than 60 years. Remission-induction chemotherapy was compared between daunomycin (DNR) 30 mg/m2 on days 1, 2, and 3 versus mitoxantrone (MTZ) 8 mg/m2 on days 1, 2, and 3, both plus cytarabine (Ara-C) 100 mg/m2 on days 1 to 7. Following complete remission (CR), patients received one additional cycle of DNR or MTZ chemotherapy and were then eligible for a second randomization between eight cycles of low-dose (LD)-Ara-C 10 mg/m2 subcutaneously every 12 hours for 1 2 days every 6 weeks or no further treatment. RESULTS A total of 242 patients was randomized to DNR and 247 to MTZ. Median age of both study groups was 68 years. Secondary AML was documented in 26% and 25% of patients in either arm. The probability of attaining CR was greater (P = .069) with MTZ (47%) than with DNR (38%). Median duration of neutropenia was 19 (DNR) and 22 days (MTZ). The greater response rate to MTZ therapy correlated with reduced occurrence of chemotherapy resistance (32% v 47%, P = .001). With a median follow-up of 6 years, 5-year disease-free survival (DFS) is 8% in each arm. Overall survival estimates are not different between the groups (6% v 9% at 5 yrs). Poor performance status at diagnosis, high WBC count, older age, secondary AML, and presence of cytogenetic abnormalities all had an adverse impact on survival. Secondary AML and abnormal cytogenetics predicted for shorter duration of CR. Among complete responders, 74 assessable patients were assigned to Ara-C and 73 to no further therapy. Actuarial DFS was significantly longer (P = .006) for Ara-C-treated (13% [SE = 4.0%] at 5 years) versus nontreated patients (7% [SE = 3%]), but overall survival was similar (P = .29): 18% (SE = 4.6%) versus 15% (SE = 4.3%). Meta-analysis on the value of Ara-C postremission therapy confirms these results. CONCLUSION In previously untreated elderly patients with AML, MTZ induction therapy produces a slightly better CR rate than does a DNR-containing regimen, but it has no significant effect on remission duration and survival. Ara-C in maintenance may prolong DFS, but it did not improve survival.

Abstract
STUDY OBJECTIVE To evaluate the usefulness of biologic and pharmacologic parameters for early identification of cisplatin-induced renal dysfunction. DESIGN Prospective evaluation of 62 consecutively admitted patients with cancer. SETTING Cancer center. PATIENTS Sixty-two consecutive patients with cancer (52 men, 10 women; mean age 61.9 yrs). INTERVENTIONS Patients received cisplatin as a single short intravenous infusion every 3 weeks. One hundred twenty-one cycles were analyzed. The dosage in the first cycle ranged between 61 and 105 mg/m2 (mean 84 mg/m2). All patients received a standard hydration protocol. MEASUREMENTS AND MAIN RESULTS Renal function was evaluated for each cycle before treatment (day 0) and before next cycle (day 21) based on the estimated creatinine clearance (Clcr). For each cycle, the weighted relative decrease (WD) of Clcr was calculated (WDClcr = 100 x [Clcr (day 0) - Clcr (day 21)]/[Clcr (day 0)](2). Total and ultrafilterable (UF) platinum were measured as a single-sample assay taken 16 hours after the end of cisplatin administration. The mean WDClcr was 0.07 min/100 ml (range -1.0 to +1.7 min/100 ml). The intensity of renal dysfunction evaluated by WDClcr was independent of cisplatin dosage, age, sex, body surface area, initial Clcr, and cycle number. Of interest, total and UF platinum concentrations were significantly correlated to WDClcr: the higher the platinum concentration, the greater the intensity of renal dysfunction. In stepwise regression analysis, UF platinum concentration was the only selected factor. The best prediction of UF platinum was obtained by stepwise regression including cisplatin dosage, initial Clcr, and cycle number (r=0.58, p<0.0001). CONCLUSION We consider our results to be a first step toward a clinical strategy to identify patients at risk for renal dysfunction after cisplatin treatment.

Abstract
PURPOSE The in vivo response to prephase corticosteroid therapy for 1 week has been described as a major prognostic factor in childhood acute lymphoblastic leukemia (ALL). Patients with less than 1,000 blasts/microL at day 8 are considered responders and have a better prognosis. This prephase therapy is usually considered as an evaluation of glucocorticoid sensitivity. In fact, it also includes one intrathecal (IT) injection of methotrexate (MTX). In this study, we try to clarify the influence of this injection of IT MTX on the response to the prephase therapy. PATIENTS AND METHODS This retrospective study analyzed the response to prephase therapy in 1,044 children with ALL entered onto the European Organization for Research and Treatment of Cancer (EORTC) trial 58881 of the Children's Leukemia Cooperative Group (CLCG). Analysis was restricted to 732 cases with an initial blast count greater than 1,000/microL. The following variables were tested to analyze response to prephase therapy: age, sex, evaluated risk factor (RF), blast count on day 0, actual dose of prednisolone administered, immunophenotype (T v non-T), and day of IT MTX. For statistical analysis, the variable day of IT MTX (D) was stratified into three groups: group 1 if D less than 2, group 2 if D > or = 2 but < or = 6, and group 3 if D greater than 6. RESULTS All variables tested had a significant influence on response to the prephase therapy. This was especially true for IT MTX: 90.4% responders in group 1, 76.9% in group 2, and 70% in group 3 (P < .001). Immunophenotype was also a major predictor of response to the prephase: 88% responders in B-lineage ALL versus 56.2% in T-lineage ALL. IT MTX had a significant influence in B-lineage ALL (96% responders in group 1, 90% in group 2, and 79% in group 3; P < .001), whereas the influence could not be detected in T-lineage ALL. CONCLUSION These results clearly demonstrate a therapeutic systemic effect of low doses of IT MTX in childhood ALL, and response to prephase therapy should not be considered as an in vivo test for cortico-sensitivity only. Earlier use of IT MTX leads to a higher percentage of responders.

Abstract
PURPOSE To assess the relevance of N-Myc gene amplification (NMA) as a prognostic factor in localized neuroblastoma (NB) and to evaluate whether less intensive adjuvant treatment is advisable in infants without NMA. PATIENTS AND METHODS Assessment of NBs included clinical and imaging data to allow tumor-node-metastasis (TNM) staging, biologic determinations (N-Myc gene analysis), and standard histology and work-up to eliminate metastatic spread (metaiodobenzylguanidine [MIBG] scintigraphy and extensive bone marrow staging). Resectability was defined according to imaging findings. Chemotherapy was indicated in children older than 1 year at diagnosis who had postoperative residual disease or lymph node (LN) involvement, in infants with NMA, or as primary treatment in children with an unresectable NB, including dumbbell tumors. Radiotherapy was recommended in children older than 1 who presented with persistent gross residual disease at the end of therapy. RESULTS Between 1990 and 1994, 316 consecutive children who presented with a localized NB were registered in the NBL 90 study. The median age was 12 months, and 42 patients had dumbbell tumors (13%). NMA was found in 22 of 225 assessable children (10%) and correlated with adverse prognostic indicators such as age older than 1 year, an abdominal primary tumor, a large tumor (T3), and unresectability. Among 186 children who had primary excision, five died of surgery-related complications. Primary chemotherapy was given to 130 patients, which allowed removal of the tumor in all but four. The 5-year overall survival (OS) and event-free survival (EFS) rates were, respectively, 91% and 84% with a median follow-up time of 36 months. The outcome of infants and older children was similar (P = .2). EFS of patients with resectable tumors was slightly better than with unresectable primary tumors (EFS, 89% v 78%; P = .02). In dumbbell NBs, neurologic recovery was achieved in 74% of cases that presented with symptoms, and initial laminectomy was avoided in 75% of children. In a univariate analysis, large tumors, high neuron-specific enolase (NSE) and lactate dehydrogenase (LDH) levels, positive LNs, macroscopic residue, and NMA adversely influenced outcome. In the multivariate analysis, NMA was the most powerful unfavorable predictive indicator: OS and EFS rates for these children were 36% and 32%, compared with 98% and 90% in nonamplified tumors (P < .001). CONCLUSION Our data confirm the overall good prognosis of localized NBs, even when unresectable. NMA is the most relevant adverse prognostic factor in localized NBs, and more intensive treatment should be investigated in these patients. Prospective studies of other biologic factors are warranted to tailor therapy more accurately. The EFS of children who underwent primary surgery was excellent, and further justifies elimination of adjuvant treatment provided they have no NMA. Despite the elimination of postoperative therapy, infants with non-NMA tumors have an excellent outcome, which suggests that initial chemotherapy can be further reduced in case of unresectable NBs.

Abstract
AIMS To determine whether the presence of disseminated bone marrow tumour cells at diagnosis is a prognostic factor for breast cancer patients at high risk of recurrence or bone metastasis, and to assess their presence as a criterion for evaluation of the potential benefits of adjuvant chemotherapy. METHODS Multiple bone marrow aspirates from 72 breast cancer patients free from metastasis were obtained during surgery at the time of diagnosis and were tested immunologically by alkaline phosphatase antialkaline phosphatase technique with a panel of three antiepithelial monoclonal antibodies (MoAb) KL1, EMA, and HMFG2. RESULTS In nine of 72 patients, with each MoAb tested, numerous strongly positive cells always isolated were observed. However, it was demonstrated that these cells were non-specifically labelled and could be found in normal controls. CONCLUSIONS There was no evidence of marrow tumour cells in 72 operable breast cancer patients. It is suggested that published results may be greatly overestimated and that non-specific labelling may be undetected. More specific MoAb should be found and a correlation with molecular biology should be performed if this criterion is to be considered as a prognostic factor.

Abstract
BACKGROUND MCL is a well-described clinicobiological entity that presents the worst prognosis of the small-cell lymphomas. No treatment is known as the reference treatment. On the basis, first, of clinicobiological similarities between MCLs and multiple myelomas and, second, of our experience of chlorambucil in high intermittent dose in MCLs, we have treated MCL with the VAD regimen both with and without chlorambucil. PATIENTS AND METHODS Thirty disseminated MCL patients from three institutions, most in relapse (70%), were treated with the classical VAD regimen: 4 weeks VAD for 12 patients and VAD with 12 mg chlorambucil (d20-d29) for 5 weeks (VAD+C) for 18 patients. Five patients received complementary high-dose therapy (Alkeran or cyclophosphamide HD with TBI) and peripheral blood stem-cell transplantation. RESULTS Complete response was achieved in 43% of the patients in which 84.5% were treated by VAD+C. The median overall survival from the diagnosis was 52 months, and from the first VAD +/- C (OSvad) was 22.5 months, with a 20.5 month (0-75) median follow-up between diagnosis and the first VAD +/- C. The OSvad was significantly better for patients with fewer than two prognostic factors (ECOG, lymphocytosis, blastic variant, LDH level, and Ki-67 score). Four of five patients treated with HDT and PBSCT were alive in CR 12.5 months (7-22) after the first VAD +/- C regimen. CONCLUSION The VAD regimen appears effective in disseminated MCL patients and even better when associated with chlorambucil. HDT and PBSCT appear promising in younger patients in CR before HDT. A multicenter prospective study is in preparation to confirm these encouraging results.

Abstract
Ondansetron, a highly selective 5-HT3 receptor antagonist, is available in an intravenous (IV) formulation and tables, but syrup would be particularly useful in children. As chemotherapy can affect taste perceptions, this study was undertaken to determine the preference between two flavors of ondansetron syrup in children undergoing chemotherapy. Fifty-nine children, randomized into a multicenter, double-blind, crossover study, each received 5 mg/m2 of IV ondansetron daily before chemotherapy. The syrup was then randomly given in two doses, one of each flavor, strawberry and grape, 30 minutes apart. The preference was assessed 30 minutes after the second dose of syrup had been administered. Taste was assessed by the child against a panel of five faces. Of those children expressing any preference, 70% preferred the strawberry flavor. Overall, 59% of children preferred the strawberry flavor, whilst 25% preferred grape (P = 0.005) and 15% expressed no preference. The only adverse event assessed as drug related by the investigator was constipation, which occurred in one patient. In conclusion, a strong preference was found for the strawberry formulation. The ondansetron syrup was safe and well tolerated.

Abstract
PURPOSE The usual therapy of osteosarcoma is neoadjuvant chemotherapy, followed by surgery, then by postoperative chemotherapy. There is no prognostic factor to predict, at diagnosis, the histologic response and final outcome. Inactivation of the retinoblastoma-susceptibility gene RB is associated with the pathogenesis of several human cancers. In primary osteosarcomas, loss of heterozygosity (LOH) at the RB locus has been found in greater than 60% of cases. The aim of this study was to determine the potential early prognostic value of LOH of RB gene on the biopsy material at diagnosis. PATIENTS AND METHODS Forty-seven patients with primary osteosarcoma, treated in four French institutions, were studied. LOH was studied by polymerase chain reaction (PCR) of an informative RB DNA polymorphism. RESULTS Assessment of LOH at the RB gene could be completed on 34 heterozygous patients only. LOH was found in 24 cases (70%). The event-free survival (EFS) rate at 60 months is 100% for patients without LOH, 43% for all patients with RB LOH, and 65% for nonmetastatic patients with RB LOH. The difference in EFS is highly significant at P = .008 and P = .024, respectively. Histologic response after preoperative chemotherapy did not show significant correlation with LOH status. CONCLUSION RB gene LOH appears to be an early predictive feature for osteosarcomas that indicates a potential unfavorable outcome. RB LOH study might shortly help to identify high-risk patients earlier. If this is verified, therapy could then be adapted earlier to the individual's real risk of relapse.

Abstract
Neuroblastomas are malignant tumors derived embryonically from the neural crest. Biological diagnosis relies on assay of urinary excretion of homovanillic acid (HVA), vanillylmandelic acid (VMA), and dopamine (DA). Spontaneous regression of these neoplasms has been reported by numerous investigators. The authors report the case of a child with neuroblastoma that illustrates the relationship between catecholamine metabolites and tumor maturation. At 1 month of age, this infant presented an adrenal neuroblastoma with multiple metastases (stage IV); the initial histological diagnosis based on examination of cutaneous metastases was neuroblastoma. At the age of 6 months, after chemotherapy, the primary tumor was resected; hepatic metastases were discovered at laparotomy. The histological diagnosis for all lesions was highly differentiated, mature ganglioneuroma-like tissue. The main biochemical abnormality at the time of diagnosis was an elevation in normetanephrine (NMN). HVA was only slightly increased but rose progressively during chemotherapy; it dropped back to normal levels after the sixth course. This case illustrates the potential benefits of separate assays of urinary methylated catecholamine metabolites for biochemical diagnosis and therapeutic management of neuroblastoma in addition to assays of HVA, VMA, and DA. Case findings suggest existence of a transformation process with maturation of the tumor involving enzymatic regulation and expression of MAO.

Abstract
OBJECTIVE The treatment of patients with non-Hodgkin's lymphoma related to the human immunodeficiency virus (HIV-NHL) is complicated by the underlying acquired immunodeficiency syndrome (AIDS). Patients without adverse prognostic factors (no AIDS prior to lymphoma, CD4+ lymphocyte counts greater than 100 x 10(6)/l and good performance status) can be cured of lymphoma and experience long-term survival. Our previous study with the intensive chemotherapy LNH84 regimen yielded a 63% complete response (CR) rate but median survival was only nine months, half of the patients died of AIDS and the other half of their lymphoma. We report here the results of a phase II study combining the same chemotherapy with zidovudine and GM-CSF. Our goal was to improve the treatment outcome over that of our previous study; GM-CSF was expected to decrease the hematological toxicity of chemotherapy and thus permit a dose intensity increase, while zidovudine was supposed to slow down the evolution of AIDS. DESIGN AND SETTING A phase II non-randomized prospective clinical trial in 7 centres. PATIENTS AND METHODS Thirty-two consecutive adult patients presenting HIV-NHL and performance status of less than three without active opportunistic infection underwent three cycles of doxorubicin 75 mg/m2, cyclophosphamide 1,200 mg/m2, vindesine 2 mg/m2 for two days, bleomycin 10 mg for two days and prednisolone 60 mg/m2 for five days (ACVB). Chemotherapy was associated with zidovudine (5 mg/kg/d) and GM-CSF (5 mu g/kg/d). The induction phase was followed by a four-month consolidation phase. RESULTS CR and PR > 75% were observed in 56% of patients; 25% of the patients died during the induction phase. These results were analogous to those of the previous study (63% and 14%, respectively). Neither hematological tolerance nor dose intensity were improved. With a mean follow-up of 23.5 months, median survival was 6.7 months. The rate of non-NHL AIDS-related death during CR was not reduced (22% in our study vs. 16% in our previous one). CONCLUSIONS GM-CSF failed to reduce significantly the cumulative hematological toxicity of chemotherapy and zidovudine. New antiviral agents without hematological toxicity would perhaps be useful in this setting.

Abstract
PURPOSE This two-arm, double-blind, randomized trial was conducted to determine the effects of lenograstim, a glycosylated recombinant human granulocyte colony-stimulating factor (rHu-G-CSF), on the hematologic tolerance of patients with sarcoma treated with mesna, doxorubicin, ifosfamide, and doxorubicin (MAID) chemotherapy. PATIENTS AND METHODS Forty-eight patients with metastatic or locally advanced soft tissue sarcoma were, following the first cycle of a combination with doxorubicin 60 mg/m2, ifosfamide 7.5 g/m2, and dacarbazine 900 mg/m2, ifosfamide 7.5 g/m2, and dacarbazine 900 mg/m2 given on days 1 to 3, randomized to receive either lenograstim 5 micrograms/kg/d by once-daily injection from day 4 to day 13, or its vehicle. For subsequent cycles, 28 patients continued on the same chemotherapy and lenograstim was systematically given as prophylactic treatment in an open manner. RESULTS Following the first cycle of MAID, the duration of neutropenia was reduced in patients who received lenograstim as compared with those who received placebo, with a median duration of neutropenia ( < 0.5 x 10(9)/L neutrophils) of 0 days (range, 0 to 3) and 5 days (range, 0 to 10), respectively (P < .001). All patients who received lenograstim had recovered at least 1 x 10(9)/L neutrophils (polymorphonuclear lymphocytes [PMN]) on day 14, compared with only one of 26 in the placebo group (P < .001). The median time to recover this neutrophil level was 12 days (range, 10 to 13) and 17 days (range, 14 to 21), respectively (P < .001). Neutropenic fever occurred in five (23%) and 15 (58%) patients respectively (P = .02). Twenty-eight patients received at least two cycles (median, four) of MAID at the same dose. Toxicity remained constant across all treatment cycles. A progressive increase in thrombocytopenia was noted, with median platelet nadirs of 102 x 10(9)/L at cycle 2 and 19.5 x 10(9)/L at cycle 6, but did not result in significant treatment modifications. Consequently, median relative dose-intensities remained greater than 0.95 for up to six consecutive MAID cycles. CONCLUSION Lenograstim significantly improved hematologic tolerance in patients treated with the MAID chemotherapy regimen and, therefore, allowed optimal adhesion to the theoretic doses planned for up to six cycles. Whether such an optimization in relative dose-intensity will result in an improvement of treatment efficacy remains to be determined.

Abstract
Dihydropyrimidine dehydrogenase (DPD) is the initial enzyme of 5-fluorouracil (5-FU) catabolism. The clinical importance of DPD has recently been demonstrated with the identification of severe and/or lethal 5-FU-related toxicity in patients with suspected or proven DPD deficiency revealed in lymphocytes. We conducted a prospective study on 185 cancer patients in order to evaluate the incidence of complete or partial DPD deficiency. The population comprised 152 men (mean age 62.1) and 33 women (mean age 59.2). Sixty eight were head and neck patients treated by a 5-day continuous infusion of 5-FU (starting dose 1 g/m2/day, with dose adaptation at mid-cycle) for which DPD activity was measured 2-3 days before 5-FU administration (94 cycles analyzed). DPD activity was measured by a radioenzymatic assay using 14C-5-FU. DPD activity showed a unimodal distribution, which globally fits a Gaussian distribution. Mean and median DPD activity were 0.222 and 0.211 nmol/min/mg prot respectively (range 0.065-0.559). No total DPD deficiency was found. Neither liver function nor age influenced DPD activity, but DPD activity was on average 15% lower in women than in men (0.194 and 0.228 nmol/min/mg prot respectively, p = 0.03). In patients treated with 5-FU, the risk of developing side effects was not linked to pretreatment DPD activity. 5-FU-related toxicity was linked to FU systemic exposure. The correlation between DPD activity and FU clearance was weak (n = 90, r = 0.31, p = 0.002). As a corollary, DPD activity in patients requiring a dose reduction was not significantly different from DPD activity in patients who did not require dose modification. From the present study it appears that total DPD deficiency is a very rare event. Although pre-treatment DPD activity cannot be a useful indicator for improving 5-FU dose adaptation strategy, the identification of partial DPD deficiency (< 0.100 nmol/min/mg prot, 3% of the population) could lead to starting the treatment with a markedly reduce 5-FU dose.

Abstract
An intrathyroid primary epithelial spindle-cell tumor with mucous cysts is described in a 9-year-old child. Histologically, this well-circumscribed tumor exhibited a nodular pattern, a prominent spindle cell component with minimal pleomorphism, and well-differentiated mucinous glands within fibrous bands. The spindle cells demonstrated diffuse immunopositivity for cytokeratin and vimentin. Electron microscopy of tissue sections demonstrated that cells contained bundles of cytoplasmic tonofilaments and numerous desmosomes. The light and electron microscopic features and immunohistochemical profile of this tumor were similar to those of recently described thyroid tumors that have been called "SETTLE" tumors (i.e., spindle epithelial tumor with thymus-like differentiation). These uncommon tumors can be considered intrathyroid thymoblastomas and must be regarded as potentially malignant lesions.

Abstract
PURPOSE The aim of the present study was to analyze the role of thymidylate synthase (TS; main cellular target of fluorouracil [FU]) and dihydropyrimidine dehydrogenase (DPD; rate-limiting enzyme of FU catabolism) in tumoral biopsies with respect to FU responsiveness. PATIENTS AND METHODS This prospective study was conducted on 62 head and neck cancer patients (six stage II, 16 stage III, and 40 stage IV). All received first-line chemotherapy with biomodulated FU (5-day continuous infusion). Before treatment, a tumor biopsy and control biopsy (symmetrical nontumoral area) were obtained. Cytosolic TS and DPD activities were measured using radioenzymatic assays. RESULTS DPD activity was detectable in all samples, without a significant difference between tumoral (median, 60 pmol/min/mg protein; range, 13 to 193) and nontumoral samples (median, 68 pmol/min/mg protein; range, 12 to 150). Tumoral TS and tumoral DPD were not significantly influenced by tumor localization or tumor staging. Among 52 tumors assessable for clinical response, we observed 46% complete responses (CRs), 33% partial responses (PRs), and 21% no responses (NRs). No relationship was demonstrated between TS activity and response to FU therapy. The comparison of tumoral DPD between complete responders and partial or nonresponders showed a trend toward significance (P = .06). In an attempt to reduce variability, we analyzed the tumoral/nontumoral DPD activity ratio; complete responders exhibited a significantly lower normalized DPD than partial or nonresponding patients (median, 0.86, 1.18, and 1.42 for CR, PR, and NR, respectively; CR v PR plus NR, P = .03). CONCLUSION Although resistance to FU is multifactorial, the present clinical study suggests that FU catabolism in target cells is probably a determinant factor for FU responsiveness in cancer patients and justifies the clinical use of specific DPD inhibitors as FU biomodulators.

Abstract
PURPOSE To analyze clinical and pharmacokinetic data of cisplatin (CP)/fluorouracil (FU)/l folinic acid (l FA) chemotherapy administered as first-line treatment to locally advanced head and neck cancer patients. PATIENTS AND METHODS Thirty-nine patients (35 men and four women; median age, 60 years; six stage III and 33 stage IV) received CP on day 1 (100 mg/m2) followed by l FA (200 mg/m2/d x 5) plus FU (500 mg/m2/d x 5) administered by continuous venous infusion (three cycles planned). Mean plasma concentrations of FU, l FA, and 5-methyltetrahydrofolate (5MTHF) over the cycle were computed. RESULTS Clinical response was assessable for 33 patients. Response rates on the primary tumor site (n = 33) were 63.7% complete responses (CRs), 24.2% partial responses (PRs), and 12.1% treatment failures. Response rates on lymph nodes (n = 27) were 40.7% CRs, 37.1% PRs, and 22.2% treatment failures. The most frequent toxicity was mucositis (36.2% of cycles grade 3 to 4). Grade 3 to 4 nausea-vomiting, diarrhea, neutropenia, and thrombocytopenia occurred in 6.7%, 1.9%, 13.3%, and 1% of cycles, respectively. Pharmacokinetic analysis showed a wide interpatient variability for both FU (mean, 1.01 mumol/L; range, 0.16 to 2.09), l FA (mean, 1.89, mumol/L; range, 0.52 to 7.88) and 5MTHF plasma concentrations (mean, 3.85 mumol/L; range, 1.30 to 8.11). A significant correlation was demonstrated between FU concentration and hematologic toxicity grade, mucositis grade, and nausea-vomiting/diarrhea grade. Regarding tumor response, patients who failed to respond significantly exhibited lower FU and total folate concentrations than patients with a CR or PR. CONCLUSION This study highlights the efficacy of CP/FU/l FA in head and neck carcinoma and establishes the clinical importance of coupled FU/FA pharmacokinetics to predict pharmacodynamic variability.

Abstract
Osteosarcoma of the vertebral column (OSV) is a rare tumor which represents 0.85% to 2% of all osteosarcomas. In 95% of the cases they manifest themselves through pains and 80% of other cases through neurological disorders. Usually located on lumbar vertebrae it can also be found on the rest of the vertebral column. Its radiologic aspect is one of lysis in 48% of cases but a condensation can also be met in 27% of cases. The differential diagnosis with an osteoblastoma is difficult and must be left in the hands of the pathologist who bases it on precise criteria (cellular pleomorphism, stroma, presence of giant cells...). The secondary osteosarcoma of the vertebral column represents 30% of all cases of OSV. The heterogeneity of the studies has made it difficult to quantify them. The prognosis of OSV is poor: survival average is of 15.3 months and relative risk of recurrence compared to a femoral lesion is of 3.9 months.

Abstract
Ten AIDS patients with Kaposi's sarcoma (four in stage II A, four in stage III A, one in stage III B and one in stage IV of the disease) were treated for 14 days with B-E8, an anti-IL-6 monoclonal antibody (IgG1), at a daily dose of 10 mg. No side-effects were observed, but no patients experienced a complete or partial response. No modification was noted in the analysis of lymphocyte subsets, except for a transient decline in the number of cells expressing CD56, accompanied by altered NK activity in four of the seven evaluable patients. Anti-IL-6 mAb prevented the binding of IL-6 to its cell membrane receptor, as documented by the decline in C reactive protein levels. However, anti-IL-6 mAb induced the circulation of significant amounts of IL-6, probably in the form of monomeric immune complexes. The sera, analysed on B9 cell line, demonstrated a stimulating activity, indicating that hypersensitive cells were able to cleave these complexes. This observation, together with the clinical inefficacy of the treatment, should prompt us to be careful with the use of unmanipulated single monoclonal antibodies, especially in cancer patients.

Abstract
The aim of this study was to evaluate the feasibility and efficacy of a protocol that includes "sandwich" chemotherapy, that is, chemotherapy alternated with radiotherapy, and reduced doses of supratentorial irradiation in children with medulloblastoma. Between March 1985 and September 1988, 70 successive children with newly diagnosed medulloblastoma from eight centers were treated in this prospective nonrandomized study. Patients were assigned to two risk groups. Group A included patients with macroscopically complete or subtotal excision, no brainstem involvement, no atypical cells in the cerebrospinal fluid, normal myelography, and who were more than 2 years of age. Group B patients encompassed those who did not fit the criteria for Group A. Two children were excluded from analysis after histological review confirmed ependymoma. Thus, a population of 68 children was selected, with 31 in Group A and 37 in Group B. Treatment consisted of two courses of the "eight drugs in 1 day" ("8/1") regimen followed by two courses of high-dose methotrexate (12 g/m2). Radiotherapy was begun during the 7th week after surgery in Group A and during the 5th week in Group B. In patients older than 2 years, the median radiation dose to the posterior fossa, the spinal axis, and the brain was 54 Gy, 36 Gy, and 27 Gy, respectively. Group B patients received postirradiation chemotherapy with four 8/1 courses monthly. The median time from surgery to radiation therapy was 50 days (range 21 to 141 days). One fatality due to chicken pox on Day 102 and one World Health Organization Grade IV infection occurred. The estimated 5- and 7-year disease-free survival (DFS) rates were 62% and 59%, respectively. These were 74% and 62% in Group A and 57% and 57% in Group B. Patient age, extent of resection, and radiation dose to the whole brain had no prognostic value. Patients with metastasis had a nonsignificant trend for a worse prognosis than patients with nonmetastatic disease (7-year DFS 45% vs. 68%, p = 0.11). In Group B, the 7-year DFS rates for children who received more or less than 30 Gy to the brain were 69% and 52% respectively (p = 0.15). There were recurrences in the posterior fossa (37%), spine (20%), and brain (20%). After a review of radiotherapeutic treatments, only one supratentorial failure could be blamed on reduction of the supratentorial radiation dose. This "sandwich" chemotherapy appeared to be feasible and did not show adverse survival data when compared to other series.

Abstract
PURPOSE We conducted a prospective study on a large set of cancer patients in an attempt to evaluate the incidence of complete or partial dihydropyrimidine dehydrogenase (DPD) deficiency as found in peripheral mononuclear cells (PMNC). PATIENTS AND METHODS One hundred eighty-five unselected consecutive cancer patients were included. The population consisted of 152 men (mean age, 62.1 years; range, 35 to 90) and 33 women (mean age, 59.2 years; range, 36 to 77). Sixty-eight were head and neck patients treated by a 5-day continuous infusion of fluorouracil (FU; starting dose, 1 g/m2/d, with dose adaptation based on pharmacokinetics) for which DPD activity was measured 2 to 3 days before FU administration (94 cycles analyzed). PMNC-DPD activity was measured by a radio-enzymatic assay using carbon-14-FU. RESULTS DPD activity in the entire population showed a unimodal distribution, which globally fits a gaussian distribution. Mean and median DPD activity values were 0.222 and 0.211 nmol/min/mg protein, respectively (range, 0.065 to 0.559). No total DPD deficiency was found. Multifactor analysis of variance showed that liver function (biologic evaluation) and age did not influence DPD activity, but that DPD activity was, on average, 15% lower in women (0.194 nmol/min/mg protein) than in men (0.228 nmol/min/mg protein) (P = .03). No difference was demonstrated between premenopausal and postmenopausal women. In patients treated with FU, the risk of developing side effects was not linked to pretreatment DPD activity. FU-related toxicity was linked to FU systemic exposure. The correlation between pretreatment DPD activity and FU systemic clearance (CI) was weak (n = 90, linear regression r = .31, P = .002). Pretreatment DPD activity in patients who required a dose reduction was not significantly different from DPD activity in patients who did not require dose modification. CONCLUSION From the present study, it appears that total DPD deficiency is a rare event. Although pretreatment DPD activity cannot be a useful indicator for improving FU dose adaptation strategy, the identification of severe DPD deficiency (< 0.100 nmol/min/mg protein) could lead to starting the treatment with a markedly reduced FU dose or even to using an alternative chemotherapy regimen.

Abstract
PURPOSE Assessment of cisplatin (CDDP) tolerance in patients more than 80 years old in good general condition who may benefit from CDDP-based treatment. PATIENTS AND METHODS Data on 35 patients older than 80 years who received one to six chemotherapy cycles (median, three cycles; total number of cycles, 98) including CDDP (60 to 100 mg/m2) were analyzed retrospectively. Before treatment, all patients had normal renal function as defined by serum creatinine (SC) levels below 132 mumol/L. Renal function was evaluated by measurement of SC and creatinine clearance (CC) before and after each course of chemotherapy. CC was calculated according to the Cockroft and Gault formula, where CC = (140 - age) x weight kg/0.814 x SC mumol/L. Renal toxicity was evaluated by the difference between prechemotherapy SC and the maximum SC level observed (delta SC) and by the difference between prechemotherapy CC and the minimal CC observed after treatment with CDDP (delta CC). The evolution of SC and CC during repeated courses of CDDP was analyzed, as were any extrarenal toxicities. RESULTS Renal function remained stable in 19 patients (54%) with delta SC less than 18 mumol/L and 18 of 35 patients (51%) with delta CC less than 9 mL/min. A slight deterioration in renal function was observed in 13 patients (37%) with delta SC greater than 18 mumol/L and less than 60 mumol/L, and with a delta CC greater than 11 mL/min and less than 21 mL/min. In three patients (9%), delta SC was greater than 60 mumol/L (71, 73, 115 mumol/L) and delta CC was greater than 21 mL/min (25, 26, 36 mL/min). There were no cases of severe renal insufficiency, clinical ototoxicity, or neurotoxicity > or = grade 2. Treatment was terminated after one or two courses in three patients because of grade 2 or 3 hematologic toxicity and in two patients for grade 3 nausea or vomiting. CONCLUSION CDDP at moderate doses can reasonably be administered to patients older than 80 years who may benefit from antineoplastic chemotherapy.

Abstract
123I-N-(di-ethylamino-2-ethyl) 4 iodobenzamide (I-BZA) has been put forward by the Clermont-Ferrand INSERM U71 group (France) as a tracer for malignant melanoma. We report on the clinical results obtained in 56 studies performed on 48 patients. Whole body scans along with spot views were obtained after injection of 185 MBq of I-BZA. The scans were read by three independent observers and correlated to the clinical findings and the other imaging modalities available, taking into account all lesions larger than 1 cm. Patients were classified into two groups on the basis of a post-treatment survey of patients: group I, in complete remission (24 scans); group II: documented metastases (32 scans). In group 1, 21 studies were truly negative. However, three studies showed positive results. Only one turned out to be a false positive (specificity 95%), the other two revealed unknown lesions and modified the patients' management. In group II, 73% of the known metastases were detected with higher sensitivities (> 80%) for eye and orbit, lung and abdomen. One false positive was reported and four new lesions were detected. I-BZA scintigraphy has the same sensitivity as immunoscintigraphy with higher specificity and without the risk of xenoimmunization. It is a useful tool for staging malignant melanoma which can improve patient management.

Abstract
A multicenter prospective study was conducted in 114 children with acute lymphoblastic leukemia receiving 4 intravenous methotrexate (MTX) courses (5 g/m2 as a 24 hour-infusion) to determine the diffusion of MTX in cerebrospinal fluid (CSF) and to correlate the drug levels to central nervous system (CNS) relapse occurrence. Serum and CSF levels were measured at the end of 446 MTX courses. A significant correlation was found between CSF and serum MTX concentration. CSF MTX level was greater than 1 mumol/l in 66% of the courses. Twelve patients (11%) failed to achieve this potentially cytotoxic drug level at the end of the 4 consecutive MTX courses: only one CNS relapse was observed and the mean age of these children was lower than that of the others. To date 9 (7.8%) children had CNS relapse and no difference was observed in terms of CSF MTX levels when compared to data of children free of CNS relapse. With a median follow up of 32 months, pharmacokinetic data during high-dose MTX therapy do not seem to be an exclusive predictive factor of CNS relapse.

Abstract
PURPOSE The aim of this study was to analyze the link between fluorouracil (FU) systemic exposure and tumor response and overall survival. PATIENTS AND METHODS One hundred eighty-six patients (162 men, 24 women) with head and neck cancer were studied. All received cisplatin plus FU for three cycles as first-line chemotherapy. The treatment consisted of cisplatin (100 mg/m2 intravenously [IV]) followed by a 5-day continuous venous infusion of FU (1 g/m2/d). The median follow-up duration for the 104 patients alive was 24 months. For each cycle, we calculated the area under the curve over the duration of pharmacokinetic follow-up (AUC0-105 h) for plasma FU. For each patient, we analyzed the averaged AUC0-105 h and the averaged total dose for the three cycles. RESULTS The response rate was 30% complete responses (CRs), 22% partial responses (PRs) more than 75%, 25% PRs less than 75%, and 23% no response (NR). Medians for averaged AUC and dose per cycle were 27,906 ng/mL h (first through third quartile, 25,398 to 31,060) and 7,000 mg (first through third quartile, 6,200 to 7,833), respectively. The tumor response was significantly linked to tumor stage (P < .001) and to averaged AUC (P = .05), but not to averaged dose. Analysis of parameters (continuous variable) expressing FU treatment intensity showed that dose did not influence survival contrary to the AUC (P = .001). The AUC remains significant (P = .025) in a multivariate analysis including tumor stage, demonstrating that the greater the FU systemic exposure, the longer the survival. CONCLUSION These results strengthen the interest of individual FU dose adaptation based on pharmacokinetics.

Abstract
Out of 744 newly diagnosed ALL children under the age of 18 years treated according to the EORTC-CLCG protocols 58831 and 58832, 28 (4%) were infants less than 1 year of age. An elevated risk factor, which takes into account the sizes of the liver and spleen and the number of circulating blasts, was present in 25 cases. Most patients had non-common ALL. Among 15 patients studied by cytogenetics, nine present chromosomal abnormalities, six of them having a t(4;11) translocation. Complete remission was achieved in 86% of cases. One patient died in complete remission of therapy-related infection. The overall EFS is 43%. It is not statistically different in very young infants as compared to infants older than 6 months. Except for patients with AUL or with t(4;11) translocation, a continuous complete remission rate above 50% can be achieved with a median follow-up of 4 years. The results obtained in infant ALL with EORTC-CLCG protocols are currently better than those obtained with some other protocols, but remains inferior when compared to the ones obtained in older children. Thus, further improvements are needed and should be evaluated in large cooperative trials.

Abstract
GB24 is a mouse monoclonal antibody raised against a common trophoblast-lymphocyte cross-reactive antigen. GB24 detects the membrane cofactor protein (MCP, CD46), a member of the complement regulatory protein family, which serves as a cofactor for factor 1 mediated cleavage of C3b. This study investigated the reactivity of GB24 on 38 breast carcinomas and 34 normal/benign breast tissues by immunochemistry as well as the reactivity of F2B7-2, an antibody specific to the decay accelerating factor (DAF, CD55) of the complement. GB24 staining was present on both normal tissue and benign lesions, but very strong diffuse reactivity was observed on carcinomas. This reactivity increased with the tumor grade. By contrast, malignant tumor cells lacked DAF expression. F2B7-2 antibody reacted weakly with benign epithelial cells. Results were studied by computer assisted image analysis to accurately define the mean optical densities. The densitometric analysis of MCP positive carcinomas showed a high intensity of the staining. Expression of MCP and DAF on MCF-7 cell lines was analyzed by flow cytometry. MCF-7 cell lines were strongly stained by mAb GB24 only. These data suggest that selectively enhanced expression of the antigen recognized by GB24 is associated with malignant breast disorders. This high expression, which may reflect a protective mechanism by which tumor cells survive complement activation, may prove useful as a marker of malignant transformation.

Abstract
A retrospective analysis was performed to determine the outcome of children with metastatic medulloblastoma given a standardised treatment programme. Of 68 consecutive patients treated in the French M7 protocol for medulloblastoma, 23 presented with metastatic disease. They were uniformly treated with surgery, and the same protocol of chemotherapy and craniospinal radiotherapy. The 7-year relapse-free survival rate is 43% for metastatic patients compared to 68% for patients with localised disease. Survival did not correlate with age, sex, location of metastases, extent of initial surgery and the dose of radiation therapy on the posterior fossa. Survival did correlate with the dose to the cranial field with a threshold dose of 30 Gy. Patients with metastatic disease have a worse prognosis and require more aggressive therapies at initial presentation. The prognostic impact of the different sites of metastatic disease requires further evaluation in cooperative studies.

Abstract
Interferons (IFNs) are very promising fluorouracil (FU) biochemical modulators. The pharmacological origin sustaining the FU-IFN synergistic interaction is not clearly understood. It was recently shown that alpha-IFN was associated with a dose-dependent decrease in FU clearance in treated patients. Dihydropyrimidine dehydrogenase (DPD) is the key regulating enzyme for FU catabolism. The effects on DPD exerted by both the IFN dose and the duration of exposure were evaluated in a panel of five human cancer cell lines. All cell lines investigated exhibited quantifiable DPD activity with inter-cell-line variability (0.118-0.318 nmol min-1 mg protein-1). A prolonged exposure to IFN (up to 5 days) was necessary to obtain a significant inhibition of DPD activity. A concentration-dependent significant decrease in DPD activity, reaching 50% of the initial activity determined for the highest IFN concentration (10(5) IU/ml), was demonstrated in all cell lines tested (5-day IFN exposure). For three cell lines, IFN potentiated the FU-induced growth inhibition in a concentration-dependent manner. Considering all cell lines and all IFN concentrations, it appears that globally, the greater the inhibition of DPD activity, the greater the FU potentiation (Spearman rank correlation on all cell lines, P = 0.011).

Abstract
Twenty-four patients with AIDS presenting with Kaposi's sarcoma of the lung were retrospectively studied to assess the merits of thoracic radiographs and of CT for the diagnosis of this disease. Evidence for Kaposi's sarcoma of the lung was given by a characteristic fiberendoscopic appearance in 10 cases and by the histologic diagnosis in 14 cases. All patients had chest radiographs and 14 patients a concomitant thoracic CT study. Chest radiographs showed perihilar opacities in 18 patients, nodules in 8, mediastinal and/or hilar adenopathies in 2 and pleural effusion in 16. Comparison of the patients who had had thoracic radiographs and a CT scan showed better detection of adenopathies, described in 2 cases on chest radiographs and 7 on CT scans, and of nodules, detected in 5 cases on chest radiographs and 6 on CT scans. In 12 patients with perihilar opacities on thoracic radiographs, CT provided a better view of the peribronchovascular distribution of these opaque areas. In 1 patient, CT showed peribronchovascular thickening while radiographs were normal. In 1 patient, both examinations were normal. This study emphasizes the merits of thoracic radiographs and, even more, of CT for the diagnosis of Kaposi's sarcoma of the lung. Peribronchovascular thickening appears to be a characteristic sign that is well analyzed with computed tomography. Since histological evidence of Kaposi's sarcoma is rarely obtained because of the aggressive nature of biopsies in such patients, CT has an important role for the diagnosis of this condition.

Abstract
OBJECTIVE To evaluate the prevalence of cardiac toxoplasmosis in a series of 182 necropsies performed between 1987 and 1991 on patients infected with the human immunodeficiency virus (HIV), to correlate this prevalence with the ante mortem diagnosis of cardiac involvement, and to assess the role of such cardiac lesions in the immediate cause of death. PATIENTS AND METHODS Complete necropsies of 182 HIV-infected patients (48 women, 134 men) were performed consecutively between 1987 and 1991. Risk factors, identified in 174 cases, included drug abuse (111/182), homosexuality (51/182), and blood transfusions (12/182). 16 samples were systematically obtained from each heart for histological study. If trophozoites or lymphocytic myocarditis were seen, immunohistochemical investigations were carried out with polyclonal antibodies for Toxoplasma gondii. An ultrastructural study was performed in four patients with toxoplasma myocarditis. Myocardial lesions were defined by the Dallas classification. Clinical data (and information on electrocardiograms and echocardiograms) were obtained from medical records. RESULTS Cardiac toxoplasmosis was diagnosed at necropsy in 21 (12%) patients. Cardiac lesions were associated with toxoplasmic encephalitis in 18 patients and were solitary in three patients. Acute diffuse myocarditis was present in 6/21, rare foci of myocarditis were seen in 8/21, and intramyocytic toxoplasmic cysts without any inflammatory reaction or necrosis were seen in 4/21. Anti-toxoplasma immunolabelling showed cardiac toxoplasmosis in three patients with lymphocytic myocarditis. Particles with the ultrastructural characteristics of Toxoplasma gondii trophozoites were seen in four cases. Six patients had presented with cardiac symptoms, confirmed by electrocardiographic and echocardiographic abnormalities during their disease course, and their cardiac lesions were directly responsible for the death. CONCLUSION Cardiac toxoplasmosis was common in this necropsy series of HIV-infected patients. Cardiac toxoplasmosis had been suspected clinically in four patients. Myocardial lesions were generally asymptomatic and were not discovered until necropsy. Solitary cardiac involvement was not uncommon reflecting parasite reactivation at a myocardial site. The incidence of cardiac toxoplasmosis in this group of immunodepressed subjects from an area with a high prevalence of this parasitic disease justifies regular follow up of such patients by electrocardiography and echocardiography as well as immediate administration of anti-toxoplasma treatment should sudden heart failure occur.

Abstract
Although Toxoplasma gondii frequently causes lesions of the central nervous system in AIDS, the exact incidence of extracerebral toxoplasmosis in these immunodepressed patients remains difficult to determine. Isolation of the parasite outside the central nervous system is rarely performed ante mortem, and most diagnoses of extracerebral toxoplasmosis are made post mortem. This article describes 23 cases of extracerebral toxoplasmosis diagnosed between 1987 and 1991 in an autopsy series of 170 patients infected with the human immunodeficiency virus (HIV). Ante mortem diagnosis of extracerebral involvement was affirmed in 4 of these 23 patients by identification of trophozoites in bronchoalveolar lavage fluid (2 cases), a surgical pulmonary biopsy specimen, and a bladder biopsy. Clinical and paraclinical findings suggested cardiac involvement in 4 other patients. Post mortem examination demonstrated disseminated toxoplasmosis in 18 cases and extracerebral monovisceral involvement in 5 cases. Extracerebral toxoplasmosis was directly responsible for the death of 6 patients. The most frequent extracerebral sites of Toxoplasma gondii involvement were the heart (21/23 cases; 91%), the lungs (14/23 cases; 61%) and the pancreas (6/23 cases; 26%). The tissular consequences of toxoplasmic involvement varied considerably, from formation of pseudocysts or cysts without any surrounding inflammatory reaction to necrotic lesions rich in neutrophilic polynuclear cells containing numerous free parasites. Immunoperoxidase study using antitoxoplasmic antibodies contributed to the diagnosis of 8 extracerebral localizations. Electron microscopy examination of a surgical lung biopsy and myocardial specimens (2 cases) demonstrated the ultrastructural characteristics of Toxoplasma gondii trophozoites.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
PURPOSE An increased risk of high-grade non-Hodgkin's lymphoma is observed in patients who are seropositive for human immunodeficiency virus (HIV). Treatment of such patients is complicated by their underlying acquired immunodeficiency syndrome (AIDS). Intensive strategies such as those used in non-HIV-related lymphoma may be poorly tolerated. However, patients without severe AIDS may derive significant benefits from such an approach. In a prospective multicenter study, treatment outcomes were assessed in 141 cases of HIV-seropositive lymphomas submitted to aggressive chemotherapy. PATIENTS AND METHODS Adult patients with lymphoma with a performance status less than 3 and no active opportunistic infection were consecutively treated with three cycles of doxorubicin 75 mg/m2, cyclophosphamide 1,200 mg/m2, vindesine 2 mg/m2 for 2 days, bleomycin 10 mg for 2 days, and prednisolone 60 mg/m2 for 5 days (ACVB). This treatment was followed by a consolidation phase of high-dose methotrexate plus leucovorin, ifosfamide, etoposide, asparaginase, and cytarabine (LNH84). Central nervous system prophylaxis with intrathecal methotrexate was routinely used. Zidovudine maintenance therapy was started after chemotherapy. Ninety-three patients had high-grade lymphomas (59 Burkitt's type) and 48 had intermediate-grade lymphomas. Disseminated stage III-IV was present in 86 patients, meningeal involvement in 29, and bone marrow infiltration in 30; 62 patients had more than 2 extranodal localizations. Lactate dehydrogenase levels were above the normal value in 95 cases. The median CD4-positive lymphocyte count was 227 x 10(6)/L. RESULTS Eighty-nine patients (63%) achieved complete remission (CR) and 19 (13%) partial remission, whereas 13 did not respond and 20 (14%) died during the course of ACVB, 8 of them from progressive disease. With a median follow-up of 28 months, median survival and disease-free survival were 9 and 16 months, respectively. Median survival for nonresponders was 5 months; 23 patients died of opportunistic infections while in persistent CR. In multivariate analysis, four factors were strongly associated with shorter survival: (1) CD4 count less than 100 x 10(6)/L, (2) performance status greater than 1, (3) immunoblastic lymphoma, and (4) prior AIDS. In the absence of all risk factors, the probability of survival at 2 years was 50%. CONCLUSION In a selected group of HIV-related lymphomas, intensive chemotherapy with LNH84 is feasible and yields a high CR rate. Survival is short due to death from HIV-related infections; however, in a subgroup of patients without adverse prognostic factors, long-term remission was observed.

Abstract
PURPOSE Despite a high cure rate of approximately 85% in Wilms' tumor by multimodality therapy, to date only four drugs are known to be active against such tumors. There is a clear need for new active drugs. PATIENTS AND METHODS Thirty-one patients with relapsed or refractory Wilms' tumor from three British and 14 French centers were treated with intravenous (IV) etoposide 200 mg/m2 daily for 5 days. Original stage was I (n = 3), II (n = 7), III (n = 9), IV (n = 10), and V (n = 2). Prior chemotherapy, administered initially or at relapse, included vincristine and dactinomycin in all cases, doxorubicin or epirubicin in 30, and ifosfamide in 20. Sites of relapse or resistant disease were lung in 13, abdomen or pelvis in six, liver in one, and multiple in 11. When entered onto the study, 12 patients were in first relapse, 10 in second relapse, and four in third or more relapse. Five had never obtained a complete remission. All but two (progressing) patients received two courses of etoposide, the second course being administered at day 21. RESULTS A complete response (CR) was documented in two patients, partial response (PR) in 11, stable disease in 10, and progressive disease (PD) in eight. The duration of response could not be evaluated, because all responding patients were subsequently treated with multimodality therapy. The major toxicities observed were neutropenia and thrombocytopenia, but most patients had been heavily pretreated. No toxic death clearly associated with etoposide was noted. CONCLUSION It is concluded that etoposide in this schedule is an active agent in Wilms' tumor and should be considered for inclusion in regimens for high-risk patients, such as those with metastatic disease at diagnosis and those who relapse after multiagent chemotherapy.

Abstract
Until now, folinic acid (FA) has been available the racemic mixture d1 FA, whose biological activity is supported by natural 1 FA. The purpose of this trial was to compare, on a pharmacokinetic, biological, and clinical basis, the racemic mixture dl FA with the pure 1 FA in the rescue of high-dose methotrexate (MTX) therapy. Eighteen children with acute lymphocytic leukemia (ALL) were entered in this trial planned with a cross-over design. Four cycles of MTX (5 g/m2, 24h CVI) were administered to each patient, with a 2-week interval between cycles. The rescue was achieved orally every 6h, starting 12h after the end of the MTX infusion, at a dose of 12 mg/m2 for dl FA and 6 mg/m2 for pure 1 FA. dl FA and 1 FA rescues were alternated from one cycle to the next. d FA, 1 FA, and the active metabolite 5-methyltetrahydrofolate (5-MTHF) were measured in plasma using a stereospecific HPLC assay. After administration of dl FA, the accumulation of d FA in plasma was confirmed: mean residual concentrations were 420 and 652 nM after 2 and 6 intakes respectively. Total active folate concentrations (1 FA + 5-MTHF) were similar between the two types of rescue: 92 and 100 nM respectively for dl FA rescue and 1 FA rescue after two intakes, 186 and 184 nM respectively for dl FA rescue and 1 FA rescue after six intakes. Intra-individual statistical analysis of total active folates (1 FA + 5-MTHF) performed on 17 patients did not show any significant difference between dl FA rescue and 1 FA rescue. For both types of rescue, MTX terminal half-lives were identical (average value 13.9 h). Considering each type of toxicity (hematologic, hepatic, renal and digestive) there was no significant difference in the proportion of toxic cycles following l FA rescue or dl FA rescue. In conclusion, the administration of the pure l FA, as compared with the administration of the racemic mixture, results in comparable blood profiles of active folates and MTX, and leads to equivalent treatment tolerance.
