Colorectal Cancer

Despite having a good rate of treatment adherence, patients who are diagnosed with high-risk stage III colorectal cancer at a younger age may have higher rates of relapse.

Drs Cohen and Lewis review the GALAXY enrollment strategy and describe the various colorectal cancer patient cohorts in the study.

This review article written by Nikia R. McFadden, MD, MAS, et al, discusses which therapies are best to treat unresectable colorectal liver metastases.

This case presents a patient with locally advanced, unresectable, mismatch repair–deficient sigmoid colon cancer who was treated with neoadjuvant chemoimmunotherapy followed by surgical resection leading to a complete pathologic response after preoperative systemic chemoimmunotherapy.

Treatment with trifluridine/tipiracil plus bevacizumab trended towards favorability despite not demonstrating statistically significant superiority in patients with metastatic colorectal cancer.

According to a study conducted at a single cancer center in Southern Maryland, patients who survived breast or prostate cancer were less likely to receive a colorectal cancer screening.

The CheckMate 9X8 trial did not hit the primary end point of progression-free survival superiority with nivolumab plus standard of care vs standard of care alone in metastatic colorectal cancer.

The observational GALAXY study found that use of a ctDNA assay could help determine which patients with colorectal cancer stand to benefit the most by receipt of adjuvant chemotherapy.

Treatment with trastuzumab deruxtecan produced promising efficacy results for patients with HER2-positive metastatic colorectal cancer.

Results from a phase 1/2 study showed that a combination of encorafenib, cetuximab, and nivolumab was well tolerated and yielded promising responses in patients with microsatellite stable BRAFV600E metastatic colorectal cancer.

Although the combination of regorafenib and pembrolizumab failed to meet significance for progression-free survival, an improvement in overall survival and disease control were observed for patients with microsatellite stable colorectal cancer.

Pembrolizumab, binimetinib , and bevacizumab led to deep and durable responses for patients with microsatellite-stable, treatment-refractory metastatic colorectal cancer.

Patients with KRAS-mutant metastatic colorectal cancer who were treated with a combination containing onvansertib had a tolerable safety profile.

Richard Kim, MD, and Lilliana Bustamante, MD, discuss the potnetial for using ctDNA to treat patients with oligometastatic colorectal cancer.

Phase 3 data indicated that primary tumor resection followed by systemic treatment produced higher 60-day mortality vs systemic treatment alone for patients with metastatic colorectal cancer.

Patients with advanced rectal cancer who were treated with up-front chemoradiotherapy plus consolidation chemotherapy experienced an improvement in pathological complete response without impacting disease-free survival.

Arfolitixorin was granted a fast track designation by the FDA for advanced colorectal cancer based on its potential to address unmet medical needs.

Drs Liliana Bustamante and Richard Kim react to limitations surrounding biomarkers used in colorectal cancer and consider how to best study the role of ctDNA moving forward.

Patients with microsatellite instability-high/mismatch repair deficient metastatic colorectal cancer treated with first-line nivolumab plus low-dose ipilimumab experienced a durable clinical benefit.

The potential impact that conclusions highlighted in a recent paper on postoperative MRD analysis in colorectal cancer may have on the management of patients with GI cancers.

Patients who had a poor pathological response to preoperative chemoradiation for advanced rectal cancer and waited 8 weeks or longer for surgery were likely to experience poor overall disease-free survival after completing neoadjuvant chemoradiotherapy.

Following presentation of a paper by Loupakis F, et al., Drs Liliana Bustamante and Richard Kim raise questions pertaining to the use of ctDNA as a biomarker when managing patients with metastatic colorectal cancer undergoing resection.

Despite not meeting its primary end point of superior progression-free survival, the phase 3 SOLSTICE trial’s secondary end point analysis will continue in patients with unresectable metastatic colorectal cancer being treated with trifluridine/tipiracil and bevacizumab.

An overview of what is currently understood about the use of ctDNA assays to help guide treatment decisions when managing patients with colorectal cancer undergoing resection of metastases.
