PURPOSE We have observed a severe atypical neuropathy (SAN) in patients with small non-cleaved-cell (SNCL) and large-cell lymphoma (LCL) treated with intensive chemotherapy and hematopoietic colony-stimulating factors (CSFs). The present analysis was undertaken in an attempt to identify factors associated with the development of this syndrome. PATIENTS AND METHODS Fifty-four adult and pediatric patients consecutively treated according to the same chemotherapy protocol were included in the analysis. Low-risk patients received three cycles of cyclophosphamide, vincristine, doxorubicin, and high-dose methotrexate (CODOX-M) while in high-risk patients this drug combination was alternated with high-dose cytarabine (ara-C), etoposide, and ifosfamide (IVAC) for a total of four cycles. Twenty-eight patients received a CSF (granulocyte [G]- or granulocyte-macrophage [GM]-CSF), and 26 patients received no CSF. A statistical analysis, which included a logistic regression model, was undertaken to examine the importance of potential contributing factors to the development of SAN. RESULTS SAN, which consisted of excruciating foot pain, usually associated with marked motor weakness, was observed in 12 patients. There was a highly significant association between the occurrence of this syndrome and the administration of CSFs, and an independent association with the cumulative dose of vincristine given in the first cycle of chemotherapy. Furthermore, the analysis suggested a synergistic effect between administration of the CSFs and vincristine in the genesis of this neuropathy. CONCLUSION Our results indicate that CSFs can precipitate SAN when given in conjunction with vincristine. The development of SAN was associated most strongly with the cumulative dose of vincristine -- the size of individual doses and the number of doses given in cycle 1 were important to the extent that they influenced the cumulative dose.

AbstractRecent advances in molecular profiling, have reclassified medulloblastoma, an undifferentiated tumor of the posterior fossa, in at least four diseases, each one with differences in prognosis, epidemiology and sensibility to different treatments. The recommended management of a lesion with radiological characteristics suggestive of MB includes maximum safe resection followed by a post-surgical MR < 48 h, LCR cytology and MR of the neuroaxis. Prognostic factors, such as presence of a residual tumor volume > 1.5 cm2, presence of micro- or macroscopic dissemination, and age > 3 years as well as pathological (presence of anaplastic or large cell features) and molecular findings (group, 4, 3 or p53 SHH mutated subgroup) determine the risk of relapse and should guide adjuvant management. Although there is evidence that both high-risk patients and to a lesser degree, standard-risk patients benefit from adjuvant craneoespinal radiation followed by consolidation chemotherapy, tolerability is a concern in adult patients, leading invariably to dose reductions. Treatment after relapse is to be considered palliative and inclusion on clinical trials, focusing on the molecular alterations that define each subgroup, should be encouraged. Selected patients can benefit from surgical rescue or targeted radiation or high-dose chemotherapy followed by autologous self-transplant. Even in patients that are cured by chemorradiation presence of significant sequelae is common and patients must undergo lifelong follow-up.

Abstract ATRA combined to anthracycline based chemotherapy is the reference treatment of newly diagnosed APL and a role for maintenance treatment is supported by many studies, but some controversies remain, like the role of AraC. Methods: We performed a joint analysis of pts &lt; 65 yrs included in studies LPA99 (Spanish PETHEMA) and APL 2000 (French -Belgian-Swiss APL group) to address some of those issues. In LPA99, pts received ATRA combined to Idarubicin (IDA) for induction, followed by 3 consolidation courses, 2 with IDA and 1 with mitoxantrone (MTZ, at cumulative dose of 50 mg/m2), and maintenance with intermittent ATRA and continuous 6MP + MTX during 2 years. Pts with high (WBC &gt; 10000/mm3) and intermediate (WBC &lt; 10000/mm3, platelets &lt; 40000/mm3) Sanz score also received ATRA during consolidation courses and higher cumulative dose of IDA (100 mg/m2), vs low risk pts (no consolidation ATRA, cumulative IDA: 80 mg/m2). No AraC was administered in LPA99 trial. For APL 2000, we restricted the analysis to treatment groups that received AraC: pts with low or intermediate Sanz score received induction with ATRA and DNR (60 mg/m2/d x 3) + AraC (200 mg/m2/d x 7) followed by consolidation with a similar course and a final DNR (45 mg/m2/d x 3) + AraC (1 g/m2/12h x 8) course and the same maintenance as in LPA99. High risk patients received the same treatment, but with intrathecal CNS prophylaxis and, in pts &lt; 60 years, AraC 2g/m2/12h x 8 during the last course. Median follow up was 30 and 22 months in LPA99 (412 pts) and APL 2000 (180 pts), respectively. Comparisons were adjusted on age, gender, WBC and platelet counts. Results: In low and intermediate risk patients (308 LPA99 pts, 97 APL 2000 pts), the CR rates, 2 year cumulative incidence of relapse (CIR), EFS and survival were 96% and 99% (p = 0.2), 2.5% and 6.9% (p = 0.05), 93% and 91% (p = 0.6), 95% and 97% (p = 0.3) in LPA99 and APL 2000 trials, respectively. In high risk patients (104 LPA99 pts, 83 APL 2000 pts), the CR rate, 2 year CIR, EFS and survival were 84% and 95% (p = 0.02), 16.0% and 3.3% (p = 0.06), 69.2% and 88.0% (p = 0.01), 82.4% and 91.2% (p = 0.04) in LPA 99 and APL 2000, respectively. Four relapses in high risk pts involved the CNS in LPA99, vs. none in APL 2000. Three and 5 pts in LPA99 and APL 2000 respectively, died in CR, from treatment toxicity. Conclusion: This analysis suggests than in pts with WBC &lt; 10000/mm3, the current PETHEMA approach yields even fewer relapses than a classical ATRA + DNR + AraC regimen, while being less myelosuppressive. This may be due to the anthracyclines used (IDA and MTZ instead of DNR) and/or to the higher cumulative dose of anthracyclines used in LPA99 trial, and possibly also to consolidation ATRA for intermediate risk pts. On the other hand, in pts with high WBC counts, APL 2000 results yielded better EFS and survival and a strong trend for fewer relapses (including relapses involving the CNS), suggesting a beneficial role for AraC, possibly at high dose, in this subset of patients

Adults and children with small non-cleaved-cell lymphoma have a similar excellent outcome when treated with the same chemotherapy regimen.

PURPOSE We have used identical treatment protocols for adults and children with small non-cleaved-cell lymphoma (SNCL) for many years and report here the results of two successive treatment regimens in these age groups. PATIENTS AND METHODS Seventy-two patients (39 adults and 33 children) were treated with protocol 77-04 between 1977 and 1985. All patients, except those with resected abdominal disease, received 15 cycles of a combination of cyclophosphamide (CTX), doxorubicin (ADR), prednisone (PRED), vincristine (VCR), high-dose methotrexate (MTX), and intrathecal (IT) therapy. Forty-one patients (20 adults and 21 children) were treated with protocol 89-C-41, which has been used since 1989. High-risk patients received four alternating cycles (with a total duration of 12 to 15 weeks) of an intensified version of protocol 77-04 without PRED (CODOX-M), and a new drug combination consisting of ifosfamide, etoposide, high-dose cytarabine (ara-C), and IT MTX (IVAC). Low-risk patients received three cycles of the CODOX-M regimen. High-risk patients were randomized to either receive or not receive granulocyte-macrophage colony-stimulating factor (GM-CSF). RESULTS Event-free survival (EFS) in protocol 77-04 was 56% at 2 years and beyond. EFS in protocol 89-C-41 was 92% at 2 years and beyond. GM-CSF was associated with increased thrombocytopenia. CONCLUSION Adults and children with SNCL have a similar prognosis when treated with the same chemotherapy. EFS in high-risk patients has been markedly improved by including IVAC in protocol 89-C-41, and excellent results can be achieved with only four cycles of therapy. In protocol 89-C-41, GM-CSF was not beneficial.

Despite intensive treatment, including consolidation immunotherapy (IT), prognosis of high-risk neuroblastoma (HR-NBL) is poor. Immune status of patients over the course of treatment, and thus immunological features potentially explaining therapy efficacy, are largely unknown. In this study, the dynamics of immune cell subsets and their function were explored in 25 HR-NBL patients at diagnosis, during induction chemotherapy, before high-dose chemotherapy, and during IT. The dynamics of immune cells varied largely between patients. IL-2- and GM-CSF-containing IT cycles resulted in significant expansion of effector cells (NK-cells in IL-2 cycles, neutrophils and monocytes in GM-CSF cycles). Nonetheless, the cytotoxic phenotype of NK-cells was majorly disturbed at the start of IT, and both IL-2 and GM-CSF IT cycles induced preferential expansion of suppressive regulatory T-cells. Interestingly, proliferative capacity of purified patient T-cells was impaired at diagnosis as well as during therapy. This study indicates the presence of both immune-enhancing as well as regulatory responses in HR-NBL patients during (immuno)therapy. Especially the double-edged effects observed in IL-2-containing IT cycles are interesting, as this potentially explains the absence of clinical benefit of IL-2 addition to IT cycles. This suggests that there is a need to combine anti-GD2 with more specific immune-enhancing strategies to improve IT outcome in HR-NBL.

OBJECTIVE: To review the use of a 600-mg clopidogrel loading dose in patients undergoing percutaneous coronary intervention (PCI). DATA SOURCES: Human clinical trials and platelet studies available through PubMed (1966–March 2005), bibliographies of pertinent articles, and citations supplied by the drug manufacturer were accessed. DATA SYNTHESIS: The administration of a 600-mg loading dose of clopidogrel can decrease the time required for maximum platelet inhibition to 2 hours compared with ⩾6 hours achieved with 300 mg. This higher loading dose has been investigated in multiple platelet studies and one observational report. Several randomized controlled trials have used a 600-mg loading dose; however, these studies were not designed to evaluate the efficacy and safety of this loading regimen. To date, only one randomized trial has compared the 600-mg loading dose with a 300-mg loading dose. CONCLUSIONS: When compared with a conventional loading regimen of 300 mg in lower-risk patients, pretreatment with clopidogrel 600 mg was shown to be more effective in reducing periprocedural events and demonstrated similar safety. Studies are needed to clarify the use of a 600-mg loading dose in higher-risk patients, with concomitant glycoprotein IIb/IIIa receptor antagonism, or when administration is delayed until immediately before or after PCI.

Abstract BACKGROUND/OBJECTIVE The introduction of German regimens, supplementing “standard” chemotherapy with both intravenous high-dose (HD-MTX) and intraventricular (IVENT-MTX) methotrexate, and North American regimens incorporating marrow-ablative chemotherapy with autologous hematopoietic cell rescue (HDCx+AuHCR), report encouraging outcomes for young children with medulloblastoma. We performed a comparative outcomes analysis of treatment strategies for young children with ClMB or A/LCMB. DESIGN/ METHODS Data from 12 prospective multi-center trials published between 2005 and 2019 for children &lt;six-years-old with ClMB or A/LCMB were reviewed; survivals were compared. RESULTS COG-9921, UKCCSG-CNS9204, COG-P9934 and SJYCO7 employing standard chemotherapy with either no or risk-based irradiation, reported 3-5-year event-free survival (EFS) of 17+/-5%, 33+/-28% (ClMB), 14+/-7% and 13.8+/-9% (ClMB) respectively, with reported EFS of 0% for A/LCMB in UKCCSG-CNS9204 and SJYCO7. HIT-SKK’87, HIT-SKK’92 and HIT-SKK’00 incorporating HD-MTX and IVENT-MTX reported 2-10-year EFS of 30–34+/-10–11% for ClMB and 33+/-27% (HIT-SSK’00) for A/LCMB. Head Start HS-I-II combined, CCG-99703 and HS-III employing induction chemotherapy, with or without HD-MTX, followed by single or tandem HDCx+AuHCR reported 3-5-year EFS of 42+/-14%, 50+/-11% and 27+/-6% for ClMB, with EFS for A/LCMB of 38+/-13% (HS-III). Finally, 5-year overall survivals for ACNS0334, without or with induction HD-MTX, are 39% and 69% respectively for ClMB and A/LCMB combined. CONCLUSIONS A trend towards better outcomes for young children with ClMB and A/LCMB is observed in trials including either HD-MTX and IVENT-MTX or including HD-MTX-containing induction chemotherapy and HDCx+AuHCR. Trials excluding HD-MTX, IVENT-MTX and HDCx+AuHCR have poorer outcomes.

Non-Hodgkin lymphomas (NHLs) are a heterogeneous group of hematologic malignancies which typically respond to standard first-line chemoimmunotherapy regimens. Unfortunately, patients with refractory NHL face a poor prognosis and represent an unmet need for improved therapeutics. We present two cases of refractory CD30+ NHL who responded to novel brentuximab vedotin- (BV-) based regimens. The first is a patient with stage IV anaplastic large cell lymphoma (ALCL) with cranial nerve involvement who failed front-line treatment with cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone (CHOEP) and second line cyclophosphamide, vincristine, doxorubicin, dexamethasone alternating with high-dose methotrexate (MTX), and cytarabine (hyperCVAD) with intrathecal- (IT-) MTX and IT-cytarabine, but responded when BV was substituted for vincristine (hyperCBAD). The second patient was a man with stage IV diffuse large B-cell lymphoma (DLBCL) with leptomeningeal involvement whose disease progressed during first-line rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) and progressed despite salvage therapy with rituximab, dexamethasone, cytarabine, and cisplatin (R-DHAP) in whom addition of BV to topotecan resulted in a significant response. This report describes the first successful salvage treatments of highly aggressive, double refractory CD30+ NHL using two unreported BV-based chemoimmunotherapy regimens. Both regimens appear effective and have manageable toxicities. Further clinical trials assessing novel BV combinations are warranted.

To improve the safety of autotransplantation for myeloma, peripheral blood stem cell (PBSC) collection was attempted in 75 previously treated patients after the administration of high-dose cyclophosphamide (HD-CTX; 6 g/m2) with or without granulocyte-macrophage colony- stimulating factor (GM-CSF). Sixty patients subsequently received melphalan 200 mg/m2 (57 patients) or melphalan 140 mg/m2 and total body irradiation (850 cGy) (3 patients) supported by both autologous bone marrow and PBSC; 38 patients received GM-CSF posttransplantation. Among 72 patients undergoing PBSC apheresis, “good” mobilization (greater than 50 colony-forming units granulocyte-macrophage [CFU-GM] per 10(5) mononuclear cells) was achieved when prior chemotherapy did not exceed 1 year and when GM-CSF was used post-HD-CTX; similarly, rapid platelet recovery to 50,000/microL within 2 weeks was associated with “good” PBSC mobilization. These same variables also predicted for rapid engraftment after autotransplantation, so that hematologic recovery (granulocytes greater than 500/microL and platelets greater than 50,000/microL) proceeded within 2 weeks among the 37 patients with “good” PBSC collection. As a result of rapid neutrophil recovery (greater than 500/microL) within a median of 2 weeks, infectious complications both post-HD-CTX and posttransplant were readily manageable, resulting in only one treatment-related death post-HD-CTX. The cumulative response rate (greater than or equal to 75% cytoreduction) for all 75 patients was 68%, with 12-month event-free and overall survival projections of about 85%. Using both bone marrow and PBSC together with GM-CSF, autotransplants are safe and appear effective in myeloma, especially when prior therapy had been limited to less than 1 year. More than 80% of transplanted patients achieved complete hematologic recovery within a median of 1 month posttransplant (granulocytes greater than 1,500/microL; platelets greater than 100,000/microL; hemoglobin greater than 10 g%), thus providing sufficient hematopoietic reserve for further chemotherapy in the event of posttransplant relapse.
