Purpose: We evaluated additional mutations in RAS wild-type (WT) metastatic colorectal cancer (mCRC) as prognostic and predictive biomarkers for the efficacy of added panitumumab to a 5-fluorouracil plus folinic acid (FU/FA) maintenance as pre-specified analysis of the randomized PanaMa trial.

Patients And Methods: Mutations (MUT) were identified using targeted next-generation sequencing (NGS; Illumina Cancer Hotspot Panel v2) and IHC. RAS/BRAF V600E/PIK3CA/AKT1/ALK1/ERBB2/PTEN MUT and HER2/neu overexpressions were negatively hyperselected and correlated with median progression-free survival (PFS) and overall survival (OS) since start of maintenance treatment, and objective response rates (ORR).

Article Synopsis
  • The PanaMa trial showed that adding panitumumab (Pmab) to fluorouracil and folinic acid (FU/FA) significantly improves progression-free survival in patients with RAS wild-type metastatic colorectal cancer after initial treatment.
  • Health-related quality of life (HRQOL) was monitored using the EORTC QLQ-C30 questionnaire throughout therapy, revealing that most aspects of HRQOL remained stable or improved during treatment.
  • Maintenance therapy with Pmab helped enhance HRQOL dimensions that worsened during initial therapy, supporting the idea that this treatment prolongs survival without adversely affecting quality of life.

This analysis of the RASH trial (NCT01729481) aimed at gaining a better understanding of the "Burden of Therapy" (BOTh) in pancreatic ductal adenocarcinoma (PDAC). In the RASH study, 150 patients with newly diagnosed metastatic PDAC were treated with gemcitabine plus erlotinib (gem/erlotinib) for four weeks. Patients who developed a skin rash during this four-week run-in phase continued with the gem/erlotinib treatment, while rash-negative patients were switched to FOLFIRINOX.

Purpose: Consensus molecular subtypes (CMSs) were evaluated as prognostic and predictive biomarkers of patients with wild-type metastatic colorectal cancer (mCRC) receiving fluorouracil and folinic acid (FU/FA) with or without panitumumab (Pmab) after Pmab + mFOLFOX6 induction within the randomized phase II PanaMa trial.

Methods: CMSs were determined in the safety set (ie, patients that received induction) and full analysis set (FAS; ie, randomly assigned patients who received maintenance) and correlated with median progression-free survival (PFS) and overall survival (OS) since the start of induction or maintenance treatment and objective response rates (ORRs). Hazard ratios (HRs) and 95% CI were calculated by univariate/multivariate Cox regression analyses.

Real-world data on the first-line treatment of patients with advanced non-small cell lung cancer (NSCLC) are still limited. The NEPTUN study evaluated effectiveness and safety of first-line nab-paclitaxel (Abraxane) plus carboplatin (nab-P/C) in patients with advanced NSCLC in routine clinical practice in Germany. Patients included in our study were aged ≥18 years, diagnosed with locally advanced or metastatic NSCLC and with decision for first-line nab-P/C in routine clinical practice.

Background/aim: People who are undergoing cancer treatment often ask themselves what they can do in addition to conventional medical therapy with regard to nutrition, activity, and complementary methods. However, we know little about the motivation why people opt for one or the other measure. The aim of this study was therefore to examine the extent of physical activity (PA), healthy nutrition, and the use of complementary methods in relation to both demographic and psychological data.

Background: Rituximab has become a standard treatment for non-Hodgkin lymphoma. Clinical studies have demonstrated the efficacy of rituximab in combination with standard chemotherapies in the treatment of follicular lymphoma (FL) and diffuse large B cell lymphoma (DLBCL) patients. This non-interventional study aimed to evaluate the effectiveness and safety of subcutaneous (SC) rituximab in routine clinical practice.

Objectives: Early tumor shrinkage (ETS) quantifies the objective response at the first assessment during systemic treatment. In metastatic colorectal cancer (mCRC), ETS gains relevance as an early available surrogate for patient survival. The aim of this study was to increase the predictive accuracy of ETS by using semi-automated volumetry instead of standard diametric measurements.

Article Synopsis
  • The XELAVIRI trial tested two treatment strategies for untreated metastatic colorectal cancer—sequential therapy versus initial combination therapy—and found that the sequential approach did not meet the criteria for non-inferiority in the overall population.
  • With a median follow-up of over 54 months, the trial indicated no significant benefits in time-to-failure-of-strategy (TFS), overall survival (OS), or progression-free survival (PFS) for the sequential treatment when compared to the combination approach, although some subgroups showed different results.
  • Importantly, non-inferiority was observed in patients older than 70 and those with RAS mutant tumors, signifying that while the overall findings were disappointing, certain demographics may benefit from the

Background: The evidence on the efficacy of anticancer therapy is limited in older patients with metastatic colorectal cancer (mCRC). This retrospective analysis of phase III FIRE-3 trial assesses the efficacy of FOLFIRI plus either cetuximab or bevacizumab according to the patients' age and sidedness of primary tumour.

Methods: The study endpoints overall response rate (ORR), progression-free survival (PFS) and overall survival (OS) were compared between younger (<65 years) and older (≥65 years) patients, followed by stratification according to primary tumour sidedness.

Introduction: Early tumor shrinkage (ETS), depth of response (DpR), and time to DpR represent exploratory endpoints that may serve as early efficacy parameters and predictors of long-term outcome in metastatic colorectal cancer (mCRC). We analyzed these endpoints in mCRC patients treated with first-line bevacizumab-based sequential (initial fluoropyrimidines) versus combination (initial fluoropyrimidines plus irinotecan) chemotherapy within the phase 3 XELAVIRI trial.

Methods: DpR (change from baseline to smallest tumor diameter), ETS (≥20% reduction in tumor diameter at first reassessment), and time to DpR (study randomization to DpR image) were analyzed.

Purpose: The randomized PANAMA trial investigated the efficacy of panitumumab (Pmab) when added to maintenance therapy with fluorouracil and folinic acid (FU/FA) in patients with wild-type metastatic colorectal cancer.

Methods: Following first-line induction therapy with six cycles of FU/FA and oxaliplatin plus Pmab, responding patients (stable disease or partial or complete remission) were randomly assigned (1:1, open-label) to maintenance treatment with either FU/FA plus Pmab or FU/FA alone. The primary objective was to demonstrate superiority of progression-free survival (PFS, time from random assignment until progression or death) in favor of FU/FA plus Pmab with a hazard ratio (HR) of 0.

Background: The XELAVIRI trial compared sequential (fluoropyrimidine and bevacizumab; irinotecan (Iri) at progression) versus initial combination therapy (fluoropyrimidine, bevacizumab, Iri) of treatment-naïve metastatic colorectal cancer (mCRC). In the confirmatory analysis, the primary end-point (non-inferiority of sequential therapy regarding time to failure of strategy, TFS) was not met. Nevertheless, significant differences regarding treatment efficacy were observed according to RAS status.

The German study groups, the German Low-Grade Lymphoma Study Group (GLSG) and Ostdeutsche Studiengruppe Hämatologie und Onkologie (OSHO), initiated in 2007 a double randomized trial to investigate efficacy and safety of rituximab maintenance versus observation in remission after randomly assigned induction treatment in the first-line follicular lymphoma. Previously untreated patients with stage II-IV follicular lymphoma in need of therapy were randomized to receive 6 cycles of R-CHOP, R-MCP, or R-FCM. Responding patients were subsequently randomized to 2 years rituximab maintenance or observation, stratified by type of immunochemotherapy, quality of remission, and Follicular Lymphoma International Prognostic Index (FLIPI).
