Retrospective analysis of randomized phase II trial (WJOG6210G) of FOLFIRI with either panitumumab or bevacizumab as second-line treatment in patients with KRAS wild metastatic colorectal cancer refractory to oxaliplatin and bevacizumab to evaluate the association of survival time and treatment efficacy (early tumor shrinkage, depth of response and best overall response) at each arm

ABSTRACT: Primary outcome(s): To evaluate the association of survival time (progression-free survival, overall survival) and treatment efficacy (early tumor shrinkage, depth of response and best overall response) at each arm (FOLFIRI+BV, FOLFIRI+Pmab) for metastatic colorectal cancer as second-line chemotherapy.

Molecular subtypes of metastatic colorectal cancer are predictive of patient response to chemo and targeted therapies (part 2)

Project description:We report that previously described molecular subtypes of colorectal cancer are associated with the response to therapy in patients with metastatic disease. We also identified a patient population with high FOLFIRI sensitivity, as indicated by their 2.7-fold longer overall survival when treated with FOLFIRI, as first-line regimen, instead of FOLFOX. Our results demonstrate the interest of molecular classifications to develop tailored therapies for patients with metastatic colorectal cancer.

TAS-102, Irinotecan, and Bevacizumab in Pre-treated Metastatic Colorectal Cancer (TABAsCO), A Phase II Clinical Trial. ClinicalTrials.gov NCT04109924

Project description:Background: The efficacy of FOLFIRI plus an antiangiogenesis biologic agent as 2nd line therapy for metastatic colorectal adenocarcinoma is limited. TAS-102 is a novel oral antimetabolite with a distinct mechanism of action from fluoropyrimidines. We evaluated the antitumor efficacy of TAS-102, irinotecan and bevacizumab in patients with pre-treated, advanced colorectal adenocarcinoma in a multicenter, phase II, single-arm study. Methods: Patients with advanced colorectal adenocarcinoma who had progressed after oxaliplatin and fluoropyrimidine and were eligible for treatment with bevacizumab were treated with irinotecan, bevacizumab, and TAS-102 in 28-day cycles. The primary endpoint was progression-free survival (PFS). Results: We enrolled 35 evaluable patients. The study was positive. The median PFS was 7.9 (90% CI 6.2-11.8) months (vs. 6 months in historical control, p=0.018). The median overall survival was 16.5 (90% CI 9.8-17.5) months. Sixty-seven percent of patients experienced grade 3 or higher treatment-related adverse events. The most common toxicities were hematological (neutropenia) and gastrointestinal (diarrhea, nausea, and vomiting). Conclusions: Irinotecan, TAS-102 and bevacizumab is an active 2nd line therapy for patients with metastatic colorectal adenocarcinoma. Neutropenia is common and can affect dose density/intensity mandating use of G-CSF. A randomized study versus standard of care therapy is warranted.

In-depth analysis of molecular network based on liquid chromatography coupled with tandem mass spectrometry in natural products: importance of redundant nodes discovery

Project description:This dataset is used for the research work entitled "In-depth analysis of molecular network based on liquid chromatography coupled with tandem mass spectrometry in natural products: importance of redundant nodes discovery". It mainly consists of two parts: Discovery of redundant nodes and Reasons of redundant nodes. The Discovery of redundant nodes section includes MS/MS data of five different natural products with distinct compound structures, namely Ginseng Radix et Rhizoma (GR): GR-neg, Epimedii Folium (EF): EF-neg, Salviae Miltiorrhizae Radix et Rhizoma (SM): SM-neg, Bufonis Venenum (BV): BV-pos, and Aconiti Lateralis Radix Praeparata (AL): AL-pos. The Reasons of redundant nodes section includes MS/MS data of GR and EF at different sample concentrations, as well as BV at different mass spectrometry parameters, such as 1-fold, 2-fold, and 10-fold dilution of GR samples (GR-1x dilution, GR-2x dilution, GR-10x dilution), 1-fold, 2-fold, and 10-fold dilution of EF samples (EF-1x dilution, EF-2x dilution, and EF-10x dilution), BV at different capillary voltages (BV-capillary-1500V-(1-6), BV-capillary-1750V-(1-6), BV-capillary-2000V-(1-6), BV-capillary-2250V-(1-6), and BV-capillary-2500V-(1-6)), BV at different sample cone voltages (BV-SC-10V-(1-6), BV-SC-20V-(1-6), BV-SC-30V-(1-6), BV-SC-40V-(1-6), and BV-SC-50V-(1-6)), and BV at different desolvation temperatures (BV-DT-300-(1-6), BV-DT-400-(1-6), and BV-DT-500-(1-6)).

Phase II study of FOLFIRI + cetuximab as induction chemotherapy followed by FOLFIRI + bevacizumab based on early tumor shrinkage in chemotherapy-naive patients with RAS wild-type colorectal cancer

Project description:Interventions: ETS was defined as 20% or more tumor reduction at 8 weeks. Patients with ETS after 8 weeks from the treatment start date continued FOLFIRI + Cmab as induction to 16 weeks, and switched to FOLFIRI +BV for maintenance of progressive disease. Patients without ETS at 8 weeks immediately switched to FOLFIRI+BV to control progression. FOLFIRI+Cmab induction therapy; Cetuximab: 250mg/m2day1 day1, 8(1cours day1:400mg/m2), CPT-11: 180mg/m2 day1, l-LV: 200mg/m2 day1, 5-FU bolus: 400mg/m2 day1, 5-FU infusion: 2400mg/m2 day1-2 FOLFIRI+BV maintenance therapy; Bevacizumab: 5mg/kg day1, CPT-11: 180mg/m2 day1, l-LV: 200mg/m2 day1, 5-FU bolus: 400mg/m2 day1, 5-FU infusion: 2400mg/m2 day1-2 Primary outcome(s): Progression free survival (PFS) Study Design: Single arm Non-randomized

Patients With Proneural Glioblastoma May Derive Overall Survival Benefit From the Addition of Bevacizumab to First-Line Radiotherapy and Temozolomide: Retrospective Analysis of the AVAglio Trial

Project description:The AVAglio and RTOG-0825 randomized, placebo-controlled phase III trials in newly diagnosed glioblastoma reported prolonged progression-free survival (PFS), but not overall survival (OS), with the addition of bevacizumab to radiotherapy/temozolomide. To establish whether certain patient subgroups derived OS benefit from the addition of bevacizumab to first-line standard-of-care therapy, AVAglio patients were retrospectively evaluated for molecular subtype, and bevacizumab efficacy assessed for each patient subgroup. A multivariate analysis accounting for prognostic covariates revealed that bevacizumab conferred a significant OS advantage versus placebo for patients with Proneural IDH1 wild-type tumors (17.1 v 12.8 months, respectively; hazard ratio, 0.43; 95% CI, 0.26 to 0.73; P = .002). This analysis also revealed an interaction between the Proneural subtype biomarker and treatment arm (P = .023). The group of patients with Mesenchymal and Proneural tumors derived a PFS benefit from bevacizumab, compared with placebo; however, this translated to an OS benefit in the Proneural subset only. Retrospective analysis of AVAglio data suggests that patients with IDH1 wild-type Proneural glioblastoma may derive OS benefit from first-line bevacizumab treatment. The predictive value of the Proneural subtype observed in AVAglio should be validated in an independent dataset.

Gene expression profile correlates with overall survival in patients with resected pancreatic adenocarinoma

Project description:Purpose/Objective(s): To correlate gene expression and overall survival (OS) in patients with pancreatic adenocarcinoma who have undergone definitive surgery Materials/Methods: Patients were identified that were treated with definitive surgery without neoadjuvant and adjuvant therapy for pancreatic adenocarcinoma. The Beaumont BioBank consented patients then collected and stored tissue samples. Patients were grouped into short term (<10 months, n=13) and long term (>20 months, n=11) survivors. RNA was extracted from fresh frozen tissues, and global gene expression patterns in the short and longer-term survivors were compared. Pathway analysis of the significant genes was also performed. Results: The median age at the time of surgery was 64 years. The mean overall survival in each group was 7.5 months and 32.0 months. We identified 163 genes that were differentially expressed between patients who survived <10 months and >20 months from their definitive surgery. Many of the genes identified have known prognostic importance in oncology; however, less than half of these genes have been reported to be associated with survival in pancreatic adenocarcinoma. Pathway analysis identified expression targets of SP1, JUN, and EGF to be highly regulated based upon differences in overall survival. Conclusions: In pancreatic adenocarcinoma patients who have undergone definitive resection, we have identified multiple genes associated with inferior survival. Many of the genes reported in this study have not previously been linked to overall survival in this patient population.
