360 Background: Angiogenesis plays an important role in NET development and progression. Axitinib is a potent and selective VEGFR-1,2,3 inhibitor, with proven activity against several vascular-dependent solid tumors. The aim of this randomized, double-blind phase II/III study was to assess the efficacy of axitinib in patients with advanced G1-2 extra-pancreatic NETs. Methods: Eligible pts were randomized (1:1) to receive octreotide LAR (30 mg IM q4w) with axitinib (5 mg BID) or placebo BID until disease progression or unacceptable toxicity. Pteswere stratified by time from diagnosis to study entry ( > or < 12m), primary tumor site (GI tract vs non-GI) and Ki-67 index (< 5% vs > 5%). Prior therapy with SSA, IFN and up to 2 lines of systemic treatment was allowed, but not prior VEGF- or VEGFR-targeted drugs. Clinical and/or radiological disease progression within 12 months prior to study entry was required. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), time to progression, overall response rate (ORR), duration of response, biochemical response and safety. Results: 256 pts were randomized (106 in the Phase II part, and 150 additional pts in the Phase III part), 126 to axitinib and 130 to placebo. The main characteristics of the study population were: median age 61 years (range: 21-85), 52% male, PS 0-1 (64-35%), G1-2 (29%-71%), primary tumor site GI (40%)-Lung (17%)-Other (32%). Prior therapies included: SSA (46%), everolimus (13%), chemotherapy (13%), TACE (5%) and PRRT (2%). ORR was significantly higher in axitinib- vs placebo-treated patients (17.5% vs 3.8%, p = 0.0004). PFS per investigator assessment also favored axitinib vs placebo-treated patients, although the difference did not reach statistical significance (median PFS 17.2 vs 12.3 months, respectively, HR 0.816, p = 0.169). Grade 3-4 treatment-related AEs occurred more frequently in the axitinib vs placebo arm (52% vs 13.8%), and included hypertension (21% vs 6 %), cardiac disorders (3.2% vs 0.7%), diarrhoea (13% vs 1.5 %), asthenia (9% vs 3%) and nausea&vomiting (2% vs 0.7%). There were 3 treatment-related deaths, 1 in the axitinib arm (cardiac failure) and 2 in the placebo arm (myocardial infarction and hepatorenal syndrome). Conclusions: Although the study failed to demonstrate a significant PFS benefit per investigator assessment, axitinib in combination with octreotide LAR demonstrated activity and had a tolerable safety profile in patients with advanced G1-2 extra-pancreatic NETs. Data base cleaning and central blinded radiological PFS assessment are currently ongoing. Clinical trial information: NCT01744249.

4082 Background: Right- (R) and left-sided (L) mCRCs exhibit different clinical and molecular features. Several retrospective analyses showed that the survival benefit of anti-EGFR-based tx is limited to RAS/BRAF wt L-sided mCRC pts, which a larger effect in the first-line setting. Few data are available concerning the anti-EGFR efficacy according to primary tumor site in third line. Methods: Pts affected by RAS/BRAF wt mCRC treated with third-line anti-EGFR-based tx or R/T were retrospectively collected. The objective of the analysis was to compare tx activity and efficacy according to tumor site. Primary endpoint was PFS; secondary endpoints were OS and RR. PFS and OS analyses were performed using Kaplan-Meier method, and survival curves were compared using the log-rank test. RR was evaluated according to RECIST criteria and it was compared in the two groups using Fisher’s exact test. Statistical significance was set at p = 0.05 for a bilateral test. Univariate and multivariate analyses for PFS and OS were performed. Results: A total of 76 RAS/BRAF wt mCRC pts, treated with third-line anti-EGFR-based tx or R/T, were enrolled. Of those, 19 (25%) pts had R-sided tumor (9 pts received anti-EGFR tx and 10 pts received R/T) and 57 (75%) pts had L-sided tumor (30 pts received anti-EGFR tx and 27 pts received R/T). As shown in the table, a significant PFS and OS benefit in favor of anti-EGFR tx vs R/T was observed in L-sided pts, while no difference both in PFS and OS was observed in R-sided pts. RR was significantly higher in L-sided pts treated with anti-EGFR vs R/T, no difference was shown in R-sided pts. At the multivariate analysis, tx regimen was indipendently associated with PFS in L-sided pts, but not in R-sided pts. Conclusions: Our study confirmed the results deriving from the retrospective analysis of the phase III study 20020408. Our results demonstrated a different benefit from third-line anti-EGFR tx according to primary tumor site, confirming the role of L-sided tumor in predicting benefit from third-line anti-EGFR vs R/T, while no difference was observed in R-sided tumors.

PURPOSE Patients with lymphoblastic non-Hodgkin's lymphoma (LB NHL) were randomized to treatment with either modified LSA2L2 or ADCOMP, which added daunorubicin (DAUN) and asparaginase (L-ASP) to the methotrexate (MTX), cyclophosphamide (CYT), vincristine (VCR), and prednisone (PRED) (COMP) regimen, in a clinical trial to determine the relative effectiveness and toxicity of the two regimens. PATIENTS AND METHODS Patients with LB NHL were eligible for this randomized study if they were less than 22 years of age at diagnosis and had < or = 25% blasts in the bone marrow. Of 307 patients registered, 281 were fully eligible and assessable. Patients were stratified by extent of disease at diagnosis. RESULTS The 5-year event-free survival (EFS) rate for patients with localized disease was 84%, and for patients with disseminated disease, 67%. There were four relapses in 28 patients with localized disease. Two hundred six patients had mediastinal primary tumors and despite local radiation, 34 of 63 failures in these patients involved the primary tumor site with or without other involvement. After adjusting for extent of disease at diagnosis, the regimens did not differ significantly with respect to risk for adverse events. The acute toxicity was primarily neutropenia and thrombocytopenia, with greater initial toxicity in patients on the LSA2L2 regimen. Three patients developed acute myelogenous leukemia. CONCLUSION Long-term EFS in children with LB NHL can be achieved in the majority of patients. Disease progression, which includes recurrence at the primary tumor site, is a major cause of treatment failure in patients with mediastinal presentations. Addition of DAUN and L-ASP to the COMP regimen does not produce a more effective treatment than LSA2L2.

ABSTRACT High doses of rifampin may help patients with tuberculous meningitis (TBM) to survive. Pharmacokinetic pharmacodynamic evaluations suggested that rifampin doses higher than 13 mg/kg given intravenously or 20 mg/kg given orally (as previously studied) are warranted to maximize treatment response. In a double-blind, randomized, placebo-controlled phase II trial, we assigned 60 adult TBM patients in Bandung, Indonesia, to standard 450 mg, 900 mg, or 1,350 mg (10, 20, and 30 mg/kg) oral rifampin combined with other TB drugs for 30 days. The endpoints included pharmacokinetic measures, adverse events, and survival. A double and triple dose of oral rifampin led to 3- and 5-fold higher geometric mean total exposures in plasma in the critical early days (2 ± 1) of treatment (area under the concentration-time curve from 0 to 24 h [AUC0–24], 53.5 mg · h/liter versus 170.6 mg · h/liter and 293.5 mg · h/liter, respectively; P < 0.001), with proportional increases in cerebrospinal fluid (CSF) concentrations and without an increase in the incidence of grade 3 or 4 adverse events. The 6-month mortality was 7/20 (35%), 9/20 (45%), and 3/20 (15%) in the 10-, 20-, and 30-mg/kg groups, respectively (P = 0.12). A tripling of the standard dose caused a large increase in rifampin exposure in plasma and CSF and was safe. The survival benefit with this dose should now be evaluated in a larger phase III clinical trial. (This study has been registered at ClinicalTrials.gov under identifier NCT02169882.)

Abstract Background Solitary fibrous tumor (SFT) is a rare soft tissue tumor originating from mesenchyme. Two cases of SFT we report right now occurred in the splenic vein and liver respectively, this primary splenic vein SFT may be the first report case, and also the first report of liver recurrence SFT cured by orthotopic liver transplantation (OLT). Case presentation One case was a 37-year-old female patient whose primary tumor site was located in the splenic vein, which resulted in splenomegaly and hypersplenism; its recurrence again and again after surgical resection and eventually transferred to the liver, during 10 years of follow-up, 4 operations were performed, and he is in a good condition right now. The second case was a 54-year-old male patient whose primary tumor site was located in the liver, spleen and left side of the chest wall; however, he had no uncomfortable symptoms. Surgeons performed two operations to remove these tumors, totally. 6 years later, SFT recurrence in the liver, and given that the tumor was so large that it could not be completely surgical resected, we chose orthotopic liver transplantation (OLT), and no tumor recurrence during 12-month follow-up. Conclusion The reports of these two cases of SFT are very rare, especially the splenic vein SFT, which expand the understanding of SFT. The main treatment of SFT is still surgical resection, right now, and liver transplantation may be a new option treatment for the huge liver SFT.
