Colorectal Cancer

After a brief overview on first-line treatment options for patients with metastatic colorectal cancer, panelists highlight the role HER2 status plays in the selection of novel therapies.

A comprehensive discussion on the barriers to molecular testing in metastatic colorectal cancer, along with challenges in utilizing these tests in the real-world setting.

Panelists consider the potential role for circulating tumor DNA to inform the selection of therapy for patients with metastatic colorectal cancer.

A renewed focus on dismantling the barriers and closing gaps in care will aid in the mission to drive down the rate of cancer mortality and incidence across disease states.

Adding trilaciclib to FOLFOXIRI and bevacizumab led to statistically significant reductions in instances of severe neutropenia during induction and duration of severe neutropenia in cycles 1 to 4. However, the combination failed to improve antitumor activity vs placebo plus FOLFOXIRI/bevacizumab in patients with metastatic colorectal cancer.

Daniel Walden, MD, discusses the association of low expression of RNA of wild-type homologous recombination genes and survival in colorectal cancer.

Shai Friedland, MD, discusses a multimodal screening blood test for advanced adenomas in colorectal cancer.

Sherise Rogers, MD, MPH, discusses the potential of utilizing circulating tumor DNA to help guide second-line treatment decisions in patients with metastatic colorectal cancer.

Scott Kopetz, MD, discussed the key objectives of the phase 3 BREAKWATER trial being done in patients with BRAF V600E–mutated mCRC, the recently reported safety and efficacy data observed with encorafenib plus cetuximab and chemotherapy, and the importance of conducting biomarker research to further personalize treatment in these patients.

Investigators in the phase 2 SWOG S2107 trial are evaluating encorafenib plus cetuximab and nivolumab for patients with previously treated, microsatellite stable, unresectable, or metastatic colorectal cancer harboring a BRAF V600E mutation.

Shared insight on the value tissue and circulating tumor DNA respectively provide in molecular testing for patients with metastatic colorectal cancer.

Experts in metastatic colorectal cancer management highlight the role of molecular testing and testing modalities available in the academic and community settings.

For decades, resection of the primary tumor, either up front or after neoadjuvant therapy, has remained the standard of care for patients with early-stage (stage I-III) colorectal cancer. Recently, a plethora of data have been published that might change the current surgery-centered paradigm.

With 2 KRAS G12C inhibitors showing encouraging results in combination with anti-EGFR agents, there is a ray of hope for patients with recurrent colon cancer–a treatment that may offer patients the chance to make it to important milestones.

The safety and efficacy of a combination regimen comprised of XL092 and atezolizumab is being compared with that of regorafenib monotherapy in patients with microsatellite stable or microsatellite instability–low metastatic colorectal cancer who have progressed on or are intolerant to standard-of-care therapy.

Dr Strickler discusses the FDA approval of tucatinib plus trastuzumab in metastatic colorectal cancer, key efficacy and safety findings from the MOUNTAINEER trial, and ongoing research seeking to address remaining unmet needs in this population.

The MOUNTAINEER-03 trial is designed to evaluate the efficacy of tucatinib and trastuzumab plus modified leucovorin calcium, fluorouracil, and oxaliplatin, compared with standard-of-care, first-line therapy for metastatic HER2-positive colorectal cancer.

John H. Strickler, MD, highlights key findings from the MOUNTAINEER trial and addresses the possibility of moving the combination up to the first line setting.

Six weeks of preoperative oxaliplatin-fluoropyrimidine chemotherapy did not increase perioperative morbidity in patients with radiologically staged T3-4, N0-2, M0 colon cancer, according to findings from the international phase 2/3 FOxTROT trial.

Marwan G. Fakih, MD, discusses a comparative analysis of the tumor microenvironment in primary tumors vs metastatic tissue in patients with microsatellite stable metastatic colorectal cancer.

J. Randolph (Randy) Hecht, MD, discusses the investigation of XL092 plus atezolizumab in patients with microsatellite stable/microsatellite instability–low metastatic colorectal cancer.

Howard S. Hochster, MD, discusses the evaluation of trastuzumab and pertuzumab vs cetuximab and irinotecan in HER2-amplified metastatic colorectal cancer.

Stacey A. Cohen, MD, discusses the investigation of the optimal timing to test for circulating tumor DNA to detect minimal residual disease following surgery in patients with stage I to III colorectal cancer.

Jason Starr, DO, discusses the characterization of POLE/POLD1 mutations in colorectal adenocarcinoma.

Van K. Morris, MD, discusses the evaluation of circulating tumor as a predictive biomarker for the use of adjuvant chemotherapy in patients with low-risk, stage II colon cancer.
