Results from the ATOMIC trial found a 50% reduction in the risk of death for patients with dMMR colon cancer receiving atezolizumab/chemotherapy.

Data from the MATTERHORN trial may be “practice-changing” in the management of resectable gastric or gastroesophageal junction adenocarcinoma.

As a single agent or in combination, MK-1084 showed promising efficacy and safety results for patients with KRAS G12C–mutated CRC.

Emergent alteration patterns were similarly diverse across treatment arms in the phase 3 CodeBreaK 300 study.

The median PFS was 54.1 months with nivolumab/ipilimumab vs 5.9 months with chemotherapy in patients with MSI-H/dMMR CRC.

Anlotinib/chemotherapy showed comparable efficacy vs bevacizumab/chemotherapy in patients with RAS/BRAF wild-type metastatic colorectal cancer.

Escalated adjuvant chemotherapy did not improve recurrence-free survival in patients with stage III colon cancer when using a ctDNA-informed approach.

T-DXd improved OS, PFS, ORR, and DOR vs ramucirumab plus paclitaxel in the second-line treatment of HER2-positive gastric cancer or gastroesophageal junction adenocarcinoma.

Updated findings from BREAKWATER support encorafenib plus cetuximab and chemotherapy as a new standard of care in BRAF V600E-mutated metastatic CRC.

A phase 2 study evaluated the efficacy of balstilimab and botensilimab in patients with MSS metastatic mCRC without liver metastases.

Fruquintinib plus best supportive care elicits a progression-free survival benefit across all prior treatment subgroups among patients with refractory metastatic colorectal cancer in the phase 3 FRESCO-2 trial.

Among patients with colorectal cancer who are ineligible for intensive chemotherapy, trifluridine/tipiracil plus bevacizumab yielded similar survival outcomes compared with capecitabine plus bevacizumab.

Data from the phase 2 DESTINY-CRC02 study support the use of trastuzumab deruxtecan at a dose of 5.4 mg/kg every 3 weeks for patients with HER2-positive metastatic colorectal cancer.

“We think that we can successfully de-escalate treatment of rectal cancer and achieve the same high cure rates [and] keep patients disease free, with less long-term toxicity and effects,” lead author Deb Schrag, MD, FASCO, MPH, said.

Results from the phase 2b HERIZON-BTC-01 trial show positive efficacy and safety responses in patients with locally advanced, unresectable or metastatic biliary tract cancer.

Patients with unresectable hepatocellular carcinoma receiving single tremelimumab regular interval durvalumab have a feasible immune-related adverse effect profile.

Findings from the phase 3 NAPOLI 3 trial support NALIRIFOX as a novel reference regimen for first-line metastatic pancreatic ductal adenocarcinoma.

Data from the PARADIGM trial that were presented at 2022 ASCO demonstrated that panitumumab plus FOLFOX should be standard of care for patients with left-sided, RAS wild-type colorectal cancer, according to Tanios S. Bekaii-Saab, MD.

Tanios S. Bekaii-Saab, MD, discussed how data from clinical trials examining different targeted strategies in colorectal cancer will transform the way in which patients with this malignancy are seen and treated.

At 2022 ASCO, Tanios S. Bekaii-Saab, MD, talks about how data from the ongoing MOUNTAINEER trial investigating trastuzumab plus tucatinib in HER2-positive metastatic colorectal cancer and other similar trials may impact the standard of care going forward.

At 2022 ASCO, Tanios S. Bekaii-Saab, MD, reviews the MOUNTAINEER trial of trastuzumab plus tucatinib for HER2-positive metastatic colorectal cancer and foreshadows how an approved regimen may help improve outcomes in this patient population.

Kim A. Reiss Binder, MD, spoke about the phase 1 CARISMA trial which investigated CAR macrophages in HER2-overexpressing solid tumors.

Cornelis J. A. Punt, MD, PhD, spoke about the phase 3 CAIRO5 trial of bevacizumab plus either FOLFOXIRI or FOLFOX/FOLFIRI for patients with initially unresectable colorectal liver metastases.
