The combination regimen was well tolerated with promising preliminary anti-tumor activity in patients with heavily pretreated esophageal cancer, who had not received immunotherapy.

“We observed much more deeper responses and more meaningful responses [in the treatment arm] compared with the placebo arm, in which 15% of the population had deep responses of ≥ 80%."

Michael J. Overman, MD, discusses the advances in testing for rare genomic alterations in colorectal cancer.

A biomarker analysis utilized liquid biopsies to find potential prognostic and predictive biomarkers for patients with BRAF V600E–mutant metastatic colorectal cancer treated with BRAF, EGFR, and/or MEK inhibitors.

Final overall survival and long-term safety results of the phase 3 NETTER-1 trial were presented during the World Congress on Gastrointestinal Cancer 2021.

Findings from the OCTOPUS Consortium of trial data have indicated that obese patients with colorectal cancer have a poorer survival from adjuvant chemotherapy treatment due to reduced treatment dose and average cumulative relative dose.

In a first-of-its-kind study, data reveal that unnecessary antibiotic use may increase the risk of colon cancer—especially in people under age 50. Findings were presented at the 2021 World Congress on Gastrointestinal Cancer.

Treatment with avapritinib in Chinese patients with PDGFRA D842V-mutant gastrointestinal stromal tumors revealed promising clinical benefit, according to a bridging study of the NAVIGATOR trial.

Pembrolizumab monotherapy demonstrated improvement in health-related quality of life in patients with previously treated metastatic microsatellite instability-high/ mismatch repair deficient advanced noncolorectal solid tumors, with the biggest improvements seen in those who achieved a complete remission or partial remission.

A phase 2 trial of tislelizumab and another trial of Tumor Treating Fields accompanied by sorafenib are filling unmet needs in advanced hepatocellular carcinoma, although more data are still needed in this space.

Increasing the dose of the primary treatment modality for anal squamous cell carcinoma, chemoradiotherapy, may further improve efficacy for patients with effective organ preservation and disease control.

A propensity score matching analysis presented in a poster during the 2021 World Congress on Gastrointestinal Cancer demonstrated that lenvatinib was superior to sorafenib as a first-line treatment for patients with unresectable hepatocellular carcinoma.
