FDA approves use of bevacizumab for patients whose colorectal cancer has worsened despite previous treatment with the drug

Source: Reuters Area: News The FDA has approved the use of bevacizumab for patients whose colorectal cancer has worsened despite previous treatment with the drug. The new use will allow patients first treated with bevacizumab plus chemotherapy to be treated again with it in combination with a different chemotherapy regimen.   The clinical data to support this indication come from the phase 3 ML18147 study in 820 patients with unresectable metastatic colorectal cancer progressing up to 3 months after discontinuing first-line bevacizumab plus chemotherapy. They were randomised to second-line chemotherapy with (n= 409) or without (= 411) bevacizumab 2.5 mg/kg per week equivalent (either 5 mg/kg every 2 weeks or 7.5 mg/kg every 3 weeks, IV). The choice between oxaliplatin-based or irinotecan-based second-line chemotherapy depended on the first-line regimen (switch of chemotherapy). The study reported that maintenance of VEGF inhibition with bevacizumab plus standard second-line chemotherapy beyond ...

ConclusionsLobar transarterial chemoembolization with the use of DEE-IRI is a technically feasible and well tolerated palliative treatment for patients with refractory liver-predominant CRC metastatic disease and has acceptable pharmacokinetics. VEGFR1 is a potential biomarker for predicting treatment efficacy and risk of adverse events.

The primary end point of this trial was to determine the feasibility and safety of transarterial chemoembolization with the use of 75 –150-μm drug-eluting embolics loaded with irinotecan (DEE-IRI) for the treatment of metastatic colorectal cancer (CRC) refractory to systemic chemotherapy.

In this study, in vitro 3D suspension coculture multicellular spheroids with core/shell cell distribution were developed on chitosan-coated surfaces. Based on the characteristic of chitosan inhibiting cell adhesion, SW620 (colon cancer cell line), 3A6 (mesenchymal stem-like cell line) and Hs68 (foreskin fibroblast line) cells could aggregate to form 3D coculture spheroids with intimate cell contacts. When cells were cocultured on chitosan, 3A6 and Hs68 cells always located in the core of spheroids and were completely enveloped by SW620 cells due to their N-cadherin protein expression following the differential adhesion hyp...

Conclusion: RAS/RAF mutations impair survival after CRS/HIPEC. The novel BIOSCOPE score reflects tumor biology, adequately stratifies long-term outcomes, and improves patient assessment and selection.

Conclusion: Our data suggest that serial measurements of CRC-associated methylation markers could be a particularly valuable tool for early response assessment in patients receiving neoCTx for CLM.

AbstractBackgroundEver since Sugarbaker has established the cytoreductive surgery (CRS) in combination with intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC), there is a chance of cure for selected patients with peritoneal metastases from colorectal cancer. Objective of this study was to investigate the benefit of CRS and HIPEC compared to other therapy options in patients with isolated synchronous and metachronous peritoneal metastases of colorectal origin in terms of long-term overall survival.MethodsA retrospective population-based cohort study, including 370 patients diagnosed with isolated synchronous a...

ConclusionsEmergency surgery for localized or regional colon cancer is associated with a greater risk of recurrence and death. This association does not appear to be due to differences in adjuvant treatment. A focus on screening and colon cancer awareness in order to reduce emergency presentations is warranted.
