Rituximab-PECC induction followed by 90 Y-ibritumomab tiuxetan consolidation in relapsed or refractory DLBCL patients who are ineligible for or have failed ASCT: results from a phase II HOVON study.

Patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) after, or ineligible for, autologous stem cell transplantation (ASCT) have a dismal prognosis. This phase II study evaluated treatment with R-PECC (rituximab, prednisolone, etoposide, chlorambucil, lomustine), every 28 days for 4 cycles in 62 patients, followed by radio-immunotherapy consolidation with 90 Y-ibritumomab tiuxetan in responsive patients. Primary endpoints were failure-free survival (FFS) and incidence of grade ≥3 adverse events from start of 90 Y-ibritumomab tiuxetan. The overall response rate after R-PECC was 50%. Twenty-nine of 31 responsive patients proceeded to 90 Y-ibritumomab tiuxetan. Five out of 15 partial remission patients converted to complete remission after 90 Y-ibritumomab tiuxetan. One-year FFS and overall survival (OS) from start of 90 Y-ibritumomab tiuxetan was 52% (95% confidence interval [CI], 33-68%) and 62% (95% CI, 42-77%), respectively. One-year FFS and OS from start of R-PECC was 28% (95% CI, 17-39%) and 49% (95% CI, 36-61%), respectively. Toxicities of R-PECC and 90 Y-ibritumomab tiuxetan were mainly haematological. In conclusion, for relapsed DLBCL patients the largely oral R-PECC regimen achieves promising response rates, combined with an acceptable safety profile. Consolidation with 90 Y-ibritumomab tiuxetan resulted in long-term response durations in approximately one third of the patients that received it.

Neoadjuvant transcatheter arterial chemoembolization and systemic chemotherapy for treatment of clear cell sarcoma of the kidney in children.

BACKGROUND: Clear cell sarcoma of the kidney (CCSK) is a rare and aggressive malignant renal tumor. We describe our experience with neoadjuvant transcatheter arterial chemoembolization (TACE) and systematic chemotherapy for the treatment of advanced CCSK in children. METHODS: Between January 2010 and December 2016, seven patients (3 boys and 4 girls; median 2.2 years) with advanced CCSK received preoperative TACE of renal artery and systemic chemotherapy. The chemoembolic emulsion for TACE consisted of cisplatin, pirarubicin, vindesine, and iodized oil. Preoperative systemic chemotherapy with vindesine, ifosfamide, and etoposide was administered three weeks after TACE. Nephrectomy was performed three weeks after systemic chemotherapy. After surgery, patients received radiotherapy and postoperative chemotherapy. RESULTS: No cardiotoxicity, renal insufficiency, or hepatic dysfunction was found in any patients. Grade II-III marrow suppression developed in four patients. One patient with tumor progress during neoadjuvant therapy failed to successfully undergo surgery and died. Six patients underwent nephrectomy after neoadjuvant therapy. Median follow-up period was 49.5 months (range, 11-83 months). Five patients have recurrence-free survival. One patient is still in postoperative chemotherapy after nephrectomy, radiotherapy and thoracoscopic resection of lung metastases. CONCLUSIONS: Neoadjuvant TACE and systemic chemotherapy appeared to be feasible in the treatment of advanced CCSK in this pilot study. THE TYPE OF STUDY: A case series with no comparison group. LEVEL OF EVIDENCE: Level IV.

Comparison of vindesine and prednisone and cyclophosphamide, etoposide, vindesine, and prednisone as first-line treatment for adult Langerhans cell histiocytosis: A single-center retrospective study.

OBJECTIVE: We compared the efficacy and clinical outcomes of vindesine and prednisone (VP) and cyclophosphamide, etoposide, vindesine, and prednisone (CEVP) regimens as first-line treatment for multisystem (MS) or multifocal single system (SS-m) adult Langerhans cell histiocytosis (LCH). METHOD: Clinical features, treatment response, and survival of adults with Langerhans cell histiocytosis treated at our center from January 2001 to January 2015 were reviewed retrospectively. RESULTS: Forty-five adult MS or SS-m LCH patients were treated (N=31, CEVP group; N=14, VP group). Both treatment groups had similar gender distributions, patient ages, and extent of disease. The non-active disease rate for both groups was 70.0% and 64.3% (P=0.775), respectively. Median follow-up was 74.9 (range: 2.8-183.6) months and recurrence rates were 71.0% and 78.6% (P=0.593), respectively. The need for second-line therapy was 64.5% and 71.4% (P=0.649), respectively, and mortality rates were 9.7% and 15.4% (P=0.586), respectively. Neutropenia occurred in 48.4% of CEVP-treated patients and 7.1% of VP-treated patients (P=0.008). CONCLUSIONS: CEVP or VP regimens for the treatment of adult SS-m or MS LCH showed similar efficacies, and both regimens were associated with high disease recurrence and the need for second-line therapy.

Relationships Between Dose Intensity, Toxicity, and Outcome in Patients with Oligodendroglial Tumors Treated with the PCV Regimen.

BACKGROUND/AIM: The drug combination of procarbazine, lomustine (CCNU) and vincristine (PCV) has been associated with efficacy in oligodendroglial gliomas (OG) when added to radiotherapy as the first line of treatment, despite the important toxicity of this treatment schedule. The aim of the present study was to analyze the tolerance, feasibility and impact of the dose intensity of the PCV regimen on outcome for patients with OG. PATIENTS AND METHODS: We retrospectively reviewed all patients with OG receiving PCV (CCNU=110 mg/m(2)) who were referred to our two Institutions. The total dose and dose adaptation, cycle delay, dose intensity, toxicity and discontinuation of CCNU were analyzed. Impacts on the outcome were evaluated. RESULTS: Between 2007 and 2011, 89 patients received PCV. PCV was administered at relapse in 73% of patients. Only 37% completed six cycles, 13.4% discontinued PCV because of toxicity, the other patients discontinued due to tumor progression. Cycle delay and dose reduction were observed for 62% and 70% patients, respectively. Grade 3 and 4 toxicities were observed in 38% and 8% patients, respectively. Among patients whose disease did not progress under the PCV regimen, discontinuation due to toxicity was significantly correlated to poor progression-free survival (PFS: p=0.023, hazard ratio=2.354) and poor overall survival (OS: p=0.021, hazard ratio=5.093). A factor that negatively impacted PFS was the absence of CCNU dose adaptation (p=0.001), while OS was negatively impacted by the absence of cycle delay (p=0.049) and grade 3/4 toxicities (p=0.045). CONCLUSION: Despite the efficacy of the PCV regimen, significant toxicity is associated with this schedule, which appears to impact its feasibility and efficacy. The optimal PCV schedule with the appropriate CCNU dose-intensity adaptation should be redefined taking into account this finding.

Dose-intensified chemotherapy alone or in combination with mogamulizumab in newly diagnosed aggressive adult T-cell leukaemia-lymphoma: a randomized phase II study.

This multicentre, randomized, phase II study was conducted to examine whether the addition of mogamulizumab, a humanized anti-CC chemokine receptor 4 antibody, to mLSG15, a dose-intensified chemotherapy, further increases efficacy without compromising safety of patients with newly diagnosed aggressive adult T-cell leukaemia-lymphoma (ATL). Patients were assigned 1:1 to receive mLSG15 plus mogamulizumab or mLSG15 alone. The primary endpoint was the complete response rate (%CR); secondary endpoints included the overall response rate (ORR) and safety. The %CR and ORR in the mLSG15-plus-mogamulizumab arm (n = 29) were 52% [95% confidence interval (CI), 33-71%] and 86%, respectively; the corresponding values in the mLSG15 arm (n = 24) were 33% (95% CI, 16-55%) and 75%, respectively. Grade ≥ 3 treatment-emergent adverse events, including anaemia, thrombocytopenia, lymphopenia, leucopenia and decreased appetite, were observed more frequently (≥10% difference) in the mLSG15-plus-mogamulizumab arm. Several adverse events, including skin disorders, cytomegalovirus infection, pyrexia, hyperglycaemia and interstitial lung disease, were observed only in the mLSG15-plus-mogamulizumab arm. Although the combination strategy showed a potentially less favourable safety profile, a higher %CR was achieved, providing the basis for further investigation of this novel treatment for newly diagnosed aggressive ATL. This study was registered at ClinicalTrials.gov, identifier: NCT01173887.

Comparison of Gefitinib versus VMP in the combination with radiotherapy for multiple brain metastases from non-small cell lung cancer.

The purpose of this study is to compare the efficacy and safety of Gefitinib versus VMP in combination with three-dimensional conformal radiotherapy (3D-CRT) for multiple brain metastases from non-small cell lung cancer (NSCLC). A total of 73 NSCLC patients with brain metastases from January 2010 to August 2013 were randomly divided into Gefitinib group (37 patients) and VMP chemotherapy group (36 patients). Patients in VMP group received VM-26 100 mg/day by intravenous injection, from day 1 to day 3, cisplatin 25 mg/m2 by intravenous injection, from day 1 to day 3. One cycle was defined as a 21-day therapy duration, with a total of 3 cycles; 2 cycles were used for consolidation. Patients in Gefitinib group received Gefitinib orally. Both groups received 3D-CRT, DT50 Gy/25f/35d from first day and target areas were treated with whole brain radiotherapy. The results of the study are listed below: There was no significant difference in the short-term effects of the two groups (P > 0.05). Median survival time (MST) of Gefitinib was 13.3 months whereas median survival time of VMP group is 12.7 months (P < 0.05). In Gefitinib group, we did not observe any difference of the median survival time between the patients with and without mutation EGFR. Toxicity of Gefitinib groups were characterized by rash, whereas chemotherapy resulted in hematologic toxicities, which included 6 cases of III/IV leucopenia (17.6 %), 3 cases of anemia (8.8 %), and 5 cases of thrombocytopenia (14.7 %), and non-hematological toxicity which was less serious symptoms for gastrointestinal disorders, hair loss, etc. These adverse reactions can be released after symptomatic treatment. No treatment-related deaths occurred. Two patients in VMP group quit due to IV leucopenia. Both oral Gefitinib and systemic VMP chemotherapy in combination with three-dimensional conformal radiotherapy (3D-CRT) could be used to treat brain metastases from non-small cell lung cancer. There were no difference in the short-term effects of the two groups, but long-term effect of Gefitinib group was slightly better than VMP group. Moreover, Gefitinib group showed low toxicity. All together, our finding implicated that Gefitinib is an effective method for patients with brain metastases from NSCLC.

A phase 1 dose escalation study of idarubicin combined with methotrexate, vindesine, and prednisolone for untreated elderly patients with primary central nervous system lymphoma. The GOELAMS LCP 99 trial.

Treatment of primary central nervous system lymphoma (PCNSL) in elderly patients remains unsatisfactory. To develop a new high-dose methotrexate (HD-MTX)-based regimen including idarubicin, a phase 1 multicenter dose escalation study was conducted to determine the maximum-tolerated dose (MTD) of idarubicin. Thirty-five immunocompetent patients with PCNSL were enrolled. The median age was 65 years (range, 60-70 years). MTX and vindesine (VDS) were given at the fixed dose of 3 g/m(2) (6-hr intravenous [IV]) and 3 mg/m(2) IV on day 1, respectively. Prednisolone (PRED) was given at the fixed dose of 60 mg/m(2) (IV or orally) on days 1-5. Idarubicin was escalated in increments of 2 mg/m(2) with doses ranging from 12-18 mg/m(2) IV on day 1. Treatment was repeated three times every 3 weeks. Dose-limiting toxicity (DLT) was defined as grade 4 neutropenia for more than 7 days, thrombocytopenia grade 4 or nonhaematological toxicity more than grade 2. The MTD of idarubicin was reached at 16 mg/m(2) . At this level, the main haematological toxicities were thrombocytopenia grade 4: 5% and neutropenia grade 3 or 4 (52%); the main nonhaematological toxicities were grade 3 or 4 infectious disease (5%) and grade 2 renal failure (9%). For the study population, median overall and progression-free survival were 19 and 13 months, respectively. Our study suggests that the MTD of idarubicin in combination with HD-MTX, VDS, and PRED, should be 16 mg/m(2) . Further studies will be necessary to challenge a standard treatment in elderly patients with PCNSL.

Phase III study of ACVBP versus ACVBP plus rituximab for patients with localized low-risk diffuse large B-cell lymphoma (LNH03-1B).

BACKGROUND: The superiority of a chemotherapy with doxorubicin, cyclophosphamide, vindesine, bleomycin and prednisone (ACVBP) in comparison with cyclophosphamide, doxorubicin, vincristin and prednisone plus radiotherapy for young patients with localized diffuse large B-cell lymphoma (DLBCL) was previously demonstrated. We report the results of a trial which evaluates the role of rituximab combined with ACVBP (R-ACVBP) in these patients. PATIENTS AND METHODS: Untreated patients younger than 66 years with stage I or II DLBCL and no adverse prognostic factors of the age-adjusted International Prognostic Index were randomly assigned to receive three cycles of ACVBP plus sequential consolidation with or without the addition of four infusions of rituximab. RESULTS: A total of 223 patients were randomly allocated to the study, 110 in the R-ACVBP group and 113 in the ACVBP group. After a median follow-up of 43 months, our 3-year estimate of event-free survival was 93% in the R-ACVBP group and 82% in the ACVBP group (P = 0.0487). Three-year estimate of progression-free survival was increased in the R-ACVBP group (95% versus 83%, P = 0.0205). Overall survival did not differ between the two groups with a 3-year estimates of 98% and 97%, respectively (P = 0.686). CONCLUSION: In young patients with low-risk localized DLBCL, rituximab combined with three cycles of ACVBP plus consolidation is significantly superior to ACVBP plus consolidation alone.

Intensified chemotherapy with ACVBP plus rituximab versus standard CHOP plus rituximab for the treatment of diffuse large B-cell lymphoma (LNH03-2B): an open-label randomised phase 3 trial.

BACKGROUND: The outcome of diffuse large B-cell lymphoma has been substantially improved by the addition of the anti-CD20 monoclonal antibody rituximab to chemotherapy regimens. We aimed to assess, in patients aged 18-59 years, the potential survival benefit provided by a dose-intensive immunochemotherapy regimen plus rituximab compared with standard treatment plus rituximab. METHODS: We did an open-label randomised trial comparing dose-intensive rituximab, doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisone (R-ACVBP) with subsequent consolidation versus standard rituximab, doxorubicin, cyclophosphamide, vincristine, and prednisone (R-CHOP). Random assignment was done with a computer-assisted randomisation-allocation sequence with a block size of four. Patients were aged 18-59 years with untreated diffuse large B-cell lymphoma and an age-adjusted international prognostic index equal to 1. Our primary endpoint was event-free survival. Our analyses of efficacy and safety were of the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT00140595. FINDINGS: One patient withdrew consent before treatment and 54 did not complete treatment. After a median follow-up of 44 months, our 3-year estimate of event-free survival was 81% (95% CI 75-86) in the R-ACVBP group and 67% (59-73) in the R-CHOP group (hazard ratio [HR] 0·56, 95% CI 0·38-0·83; p=0·0035). 3-year estimates of progression-free survival (87% [95% CI, 81-91] vs 73% [66-79]; HR 0·48 [0·30-0·76]; p=0·0015) and overall survival (92% [87-95] vs 84% [77-89]; HR 0·44 [0·28-0·81]; p=0·0071) were also increased in the R-ACVBP group. 82 (42%) of 196 patients in the R-ACVBP group experienced a serious adverse event compared with 28 (15%) of 183 in the R-CHOP group. Grade 3-4 haematological toxic effects were more common in the R-ACVBP group, with a higher proportion of patients experiencing a febrile neutropenic episode (38% [75 of 196] vs 9% [16 of 183]). INTERPRETATION: Compared with standard R-CHOP, intensified immunochemotherapy with R-ACVBP significantly improves survival of patients aged 18-59 years with diffuse large B-cell lymphoma with low-intermediate risk according to the International Prognostic Index. Haematological toxic effects of the intensive regimen were raised but manageable. FUNDING: Groupe d'Etudes des Lymphomes de l'Adulte and Amgen.

Survival impact of rituximab combined with ACVBP and upfront consolidation autotransplantation in high-risk diffuse large B-cell lymphoma for GELA.

BACKGROUND: As rituximab combined with CHOP improves complete remission and overall survival in diffuse large B-cell lymphoma, intensified chemotherapy followed by autologous stem-cell transplantation has also been advocated for high-risk patients. The aim of this study was to establish whether or not combining rituximab with high-dose chemotherapy and auto-transplantation also benefits patient survival. DESIGN AND METHODS: The LNH2003-3 study was a phase II trial including diffuse large B-cell lymphoma patients with 2 or 3 International Prognostic Index factors. They received four cycles of intensive biweekly chemotherapy with rituximab, doxorubicine, cyclophosphamide, vindesine, bleomycine, prednisolone (R-ACVBP) followed by auto-transplantation in responding patients. Two hundred and nine patients under 60 years of age were included in the study and 155 responding patients underwent auto-transplantation. In addition, a case-control study was performed by matching (1:1) 181 patients treated with R-ACVBP with ACVBP patients not given rituximab but submitted to auto-transplantation from the previous LNH1998-3 trial. RESULTS: With a median follow up of 45 months, 4-year progression-free survival and overall survival were estimated at 76% (CI: 69-81) and 78% (CI: 72-83), respectively. There was no difference between patients with 2 or 3 International Prognostic Index factors. Four year progression-free survival was significantly higher in R-ACVBP than ACVBP patients (74% vs. 58%; P=0.0005). There was also a significant increase in 4-year overall survival (76% vs. 68%; P=0.0494). CONCLUSIONS: In high-risk diffuse large B-cell lymphoma patients, treatment with R-ACVBP followed by auto-transplantation results in a 78% 4-year overall survival which should be compared to other approaches.

Vindesine-induced neuropathy mimicking Guillain-Barré syndrome.

A 13-year-old girl with acute lymphoblastic leukaemia, who was being treated with chemotherapy (including vindesine), developed paraplegia without paresthesia, which mimic Guillain-Barré syndrome. Spinal fluid analysis showed a normal protein level, vindesine neuropathy seemed to be the cause of the patient's neurological symptoms. The patient seemed to benefit from human normal immunoglobulin therapy and recovered 4 weeks later.

Adjuvant treatment with vindesine in comparison to observation alone in patients with metastasized melanoma after complete metastasectomy: a randomized multicenter trial of the German Dermatologic Cooperative Oncology Group.

To evaluate the efficacy and safety of vindesine in patients with metastatic melanoma after complete metastasectomy. One hundred and forty-two patients with metastatic spread to regional sites, lymph nodes, and distant sites after complete metastasectomy were randomized to receive either treatment with vindesine for 2 years or observation alone. Vindesine 3 mg/m intravenously was administered biweekly for the first 26 weeks following 3-week intervals for an additional 26 weeks and thereafter every 4 weeks for 52 weeks. One hundred and thirty-nine patients were eligible for intent-to-treat analysis. Median follow-up time was 46 months. Median recurrence free survival was 7.9 months in the vindesine group and 7.6 months in the observational group (P=0.40). Three-year overall survival rate was 54.9% (37 patients) for patients receiving vindesine in comparison to 43.6% (31 patients) in the observation arm (P=0.07). No grade IV toxicity was observed. The two major side effects in the vindesine group were alopecia and peripheral neuropathy. Ten patients went off treatment because of grade III toxicity. Adjuvant treatment with vindesine did not significantly prolong disease free or overall survival in high-risk melanoma patients. Thus, this randomized trial did not confirm earlier reports of beneficial effects of adjuvant vindesine and can therefore not be recommended.

Razoxane and vindesine in advanced soft tissue sarcomas: impact on metastasis, survival and radiation response.

BACKGROUND: The treatment options in advanced soft tissue sarcomas (STS) are limited. In a pilot study, an antimetastatic and radiosensitizing treatment concept was explored. PATIENTS AND METHODS: Twenty-one patients with unresectable and/or oligometastatic STS received the drugs razoxane and vindesine supported by radiotherapy and surgery. Long-term treatment was intended in metastatic disease. Forty-one patients with comparable stages of STS treated with contemporary chemotherapy served as non-randomised controls. The prognostic parameters of the groups were comparable. RESULTS: In the study group, the median number of new metastases after 6 months was 0 (range, 0-40) and after 9 months likewise 0 (0-70). The corresponding numbers in the control group were 4.5 (range, 0-40) and 9 (0->100) (p<0.001). The progression-free survival at 6 months was 71% in the study group and 23% in the controls, and the median survival time from the occurrence of the first metastasis was 16 months versus 9 months. The rate of major responses under radiotherapy combined with razoxane and vindesine was 88%, and in the control group 62% (p=0.007). The combined treatment was associated with a low to moderate toxicity. CONCLUSION: The treatment combination inhibited the development of remote metastases in the majority of patients with STS and prolonged survival to some extent.

Fatal accidental intrathecal injection of vindesine.

A 25-year-old woman being treated for non-Hodgkin's lymphoma was accidentally given vindesine intrathecally. The error was recognized immediately and a spinal cord washing was performed through syringing with isotonic saline. However, the patient died 6 weeks later with increasing paralysis, which was followed by neurologic failure. The deceased was autopsied and the central nervous system was removed for a microscopic examination. The results showed microscopic lesions extending from the lumbar to the thoracic portion of the spinal cord, which included pseudocystic transformation of the cells, degeneration of myelin, and microhemorrhages. The brain was edematous and, in the cerebellum, the vermis showed a loss of granule and Purkinje cells. The authors compare this report on vindesine toxicity with cases in the literature involving vincristine. The treating physician admitted responsibility and was sentenced to both a fine and imprisonment.

Long-term survival in post-transplant lymphoproliferative disorders with a dose-adjusted ACVBP regimen.

Post-transplant lymphoproliferative disorders (PTLD) are severe complications after solid organ transplantation with no consensus on best treatment practice. Chemotherapy is a therapeutic option with a high response and a significant relapse rate leading to a low long-term tolerance rate. Currently, most centres use anthracycline-based drug combinations, such as CHOP (cyclophosphamide, doxorubicin, vincristine and prednisone). We assessed the efficacy and safety of a dose-adjusted ACVBP (doxorubicin reduced to 50 mg/m(2), cyclophosphamide adjusted to renal function, vindesine, bleomycin, prednisone) regimen in patients failing to respond to a reduction in immunosuppressive therapy. Favourable responses were observed in 24 (73%) of the 33 treated patients. Fourteen (42%) patients died, mostly from PTLD progression. Actuarial survival was 60% at 5 years and 55% at 10 years. Survival prognostic factors were: number of involved sites (P = 0.007), clinical stage III/IV (P = 0.004), bulky tumour (P < 0.0001), B symptoms (P = 0.03), decreased serum albumin (P = 0.03) and poor performance status (P = 0.06). Both the international and the PTLD prognostic index were predictive for survival (P = 0.001 and P = 0.002, respectively). Overall 128 cycles were given. Grade 3 or 4 neutropenia was recorded after 26 (20%) chemotherapy cycles in 19 (58%) patients. Forty-one (32%) infections were recorded in 26 (79%) patients. This study demonstrated that an individual dose-adjustment of ACVBP regimen was manageable in PTLD patients and favourably impacted on long-term survival.
