United States Military Health System beneficiaries with colon cancer are more likely to have improved survival outcomes vs the general population, with a particularly notable benefit in Black patients.

Although pembrolizumab added to chemoradiotherapy was well tolerated in patients with stage II/III locally advanced rectal cancer, the neoadjuvant rectal score vs FOLFOX/chemoradiotherapy suggest that further study into its utility in this setting may not be supported.

Personalized risk assessments that utilize pathogenic variations can help detect CRC early in patients with Lynch Syndrome.

Data from a first-of-its-kind study indicated that unnecessary use of antibiotics may lead to early-onset colon cancer.

Findings from the OCTOPUS Consortium of trial data indicated that weight-based chemotherapy dosing may improve outcomes for obese patients with colorectal cancer.

More elderly, frail patients with colorectal cancer were able to complete adjuvant chemotherapy following geriatric intervention.

CancerNetwork® sat down with Marwan G. Fakih, MD, of City of Hope at the 2021 ASCO Annual Meeting to talk about a potential multidisciplinary treatment approach to colorectal cancer with regorafenib/nivolumab.

NRG-GI004/SWOG-S1610: Colorectal Cancer Metastatic dMMR/MSI-H Immunotherapy (COMMIT) Study: A Randomized Phase 3 Study of mFOLFOX6/Bevacizumab/Atezolizumab Combination vs Single Agent Atezolizumab in the First-Line Treatment of Patients With Deficient DNA Mismatch Repair (dMMR)/Microsatellite Instability–High (MSI-H) Metastatic Colorectal Cancer (NCT02997228).

Individuals with an early-onset colorectal cancer diagnosis had a survival benefit versus those at later ages, especially for patients younger than 50 years old.

The new data may put to rest concerns that adding perioperative systemic therapy might worsen outcomes in patients slated for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

In line with responses seen at the primary analysis, final results of a phase 2 trial support activity of trastuzumab deruxtecan in HER2-positive metastatic CRC.

Adding panitumumab to 5-FU and leucovorin significantly improved PFS compared with 5-FU/leucovorin alone as a maintenance therapy for patients with RAS wild-type metastatic CRC.

Certain patients with RAS wild-type colorectal cancer should be treated with bevacizumab in place of cetuximab in combination with FOLFOXIRI.

Phase 2 data presented at the 2021 ASCO Annual Meeting indicate that more than half of patients with previously treated advanced colorectal cancer who were treated with pembrolizumab plus lenvatinib were alive at 6 months.

Recommendations published in JAMA are set to change colorectal cancer screening guidance for all individuals in the United States.

Holowatyj detailed the benefits of a conference like that of the American Association for Cancer Research Annual Meeting 2021, which presents opportunities for thought leaders to come together.

FOLFIRINOX initiated before standard therapy may offer better disease-free survival for patients with rectal cancer.

Holowatyj spoke about the molecular differences of early-onset colorectal cancer by race, while maintaining that race is a social construct, leading to a multitude of options for future research.

The lead author from a study presented at the American Association for Cancer Research Annual Meeting 2021 explained the main findings regarding potential differences in tumor mutation burden by race in patients with early-onset colorectal cancer.

Holowatyj touched on the need to learn more about the biological factors contributing to disparities in early-onset colorectal cancer and the associated burden of the disease.

A phase 3 trial found that pembrolizumab for patients with microsatellite instability–high or mismatch repair–deficient metastatic colorectal cancer significantly improved health-related quality of life compared with chemotherapy.
