David S. Hong, MD, and David Sommerhalder, MD, discuss the unmet needs for patients with KRAS G12C–mutant non–small cell lung cancer (NSCLC) and colorectal cancer (CRC) that prompted the initiation of the RMC-6291-001 trial; the key efficacy and safety findings with RMC-6291 in patients with NSCLC and CRC; and potential next steps for this agent.

The novel mRNA biomarkers in the noninvasive ColoAlert® screening test displayed sensitivity and specificity for detecting colorectal cancer and advanced adenomas that could be precursors to CRC.

The FDA has approved the CRCdx® RAS Mutation Detection Kit as a companion diagnostic for panitumumab in the treatment of patients with metastatic colorectal cancer, according to an announcement from EntroGen.

A new drug application seeking the approval of fruquintinib for the treatment of adult patients with previously treated metastatic colorectal cancer has been submitted to Japan’s Ministry of Health, Labour, and Welfare.

Jeremy C. Jones, MD, discusses the applications of circulating tumor DNA testing in colorectal cancer.

Circulating tumor DNA status at the time of postoperative minimal residual disease is a prognostic factor of recurrence for patients with radically resected stage II to IV colorectal cancer

Although findings from the International Duration Evaluation of Adjuvant Therapy collaboration in 2018 failed to demonstrate the noninferiority of 3 months of adjuvant chemotherapy vs 6 months for patients with stage III colon cancer, clinically relevant data in subgroup analyses have influenced practice prescribing patterns, according to a retrospective analysis.

The integration of novel mRNA biomarkers into the ColoAlert® screening test resulted in high sensitivity and specificity for colorectal cancer.

Marwan G. Fakih, MD, expands on long-term findings from the phase 2/3 PROSPECT trial and how these findings may influence the optimal use of nonoperative management strategies in locally advanced rectal cancer.

Howard S. Hochster, MD, discusses data from the phase 3 FRESCO-2 trial of fruquintinib plus best supportive care in metastatic colorectal cancer.

Daneng Li, MD, discusses the evolution of treating patients with HER2-positive colorectal cancer and highlights the effects of implementing HER2-targeted therapy in this patient population.

The FDA has granted 2 breakthrough therapy designations to trastuzumab deruxtecan for the treatment of patients with unresectable or metastatic HER2-positive solid tumors that have progressed after prior treatment and who have no satisfactory alternative treatment options, and for those with HER2-positive metastatic colorectal cancer who have received at least 2 prior lines of therapy.

Thierry André, MD, discusses the investigation of trifluridine/tipiracil plus bevacizumab in patients with metastatic colorectal cancer, including how its use as a standard of care in the third line supported its investigation in the first-line setting, the regimen’s efficacy and safety in the SOLSTICE trial, and the importance of this combination for patients in this space despite negative trial results.

Arvind Dasari, MD, MS, presents data from the FRESCO-2 clinical trial evaluating fruquintinib in patients with refractory metastatic colorectal cancer, and provides insights on the clinical implications of the results.

Circulating tumor DNA status at the time of postoperative minimal residual disease assessment was found to be a prognostic factor for disease-free survival in patients with radically resected stage II to IV colorectal cancer.

Michael Cecchini, MD, expands on key updates in gastrointestinal cancer from the 2023 ASCO Annual Meeting, including the clinical significance of findings from the PROSPECT and phase 3 PRODIGE 23 trials of perioperative chemotherapy vs selective standard chemoradiation.

Megan Hitchins, PhD, discusses the rationale for conducting an analysis on the prevalence of high-risk constitutional MLH1 methylation in patients with early-onset colorectal cancer and endometrial cancer.

HER2 amplification appears to be prognostic in patients with RAS wild-type metastatic colorectal cancer but may not be predictive of survival benefit as a first-line treatment option in combination with panitumumab vs standard-of-care bevacizumab.

Oncologists globally explore trends, challenges in diagnosis, and future directions in patients with colorectal cancer.

Marwan G. Fakih, MD, discusses the main objective and design of the observational BASECAMP-1 study and how it functions alongside the phase 1/2 EVEREST-1 study in patients with solid tumors.

Patients with mismatch repair–deficient and/or microsatellite instability metastatic colorectal cancer experienced a progression-free survival benefit with longer disease control following treatment with avelumab compared with standard second-line chemotherapy.
