Romain Cohen, MD, PhD, on Colon Cancer: Prognostic Value of Tumor Deposits
2021 Gastrointestinal Cancers Symposium
Romain Cohen, MD, PhD, of the Mayo Clinic and Sorbonne University, discusses a post-hoc analysis of phase III results from the CALGB/SWOG 80702 study, which showed that adding the number of tumor deposits, a negative prognostic factor, to the count of lymph node metastases may improve the accuracy of TNM staging (Abstract 10).
Tenna V. Henriksen, PhD Candidate, of Aarhus University, discusses her findings on how circulating tumor DNA may help assess recurrence risk and the benefit of adjuvant therapy, and more quickly detect early relapse after treatment in patients with colorectal cancer (Abstract 11).
Andrew X. Zhu, MD, PhD, of Massachusetts General Hospital, discusses final results from the phase III ClarIDHy study, which showed that ivosidenib may improve overall and progression-free survival compared with placebo in patients with previously treated cholangiocarcinoma and an isocitrate dehydrogenase 1 mutation (Abstract 266).
Richard S. Finn, MD, of the UCLA Medical Center, discusses updated results from the IMbrave 150 study, which showed atezolizumab plus bevacizumab provides the longest overall survival seen in a front-line phase III study in advanced hepatocellular carcinoma, confirming this combination as the standard of care for patients with previously untreated, unresectable disease (Abstract 267).
Talia Golan, MD, of the Oncology Institute, Sheba Medical Center, discusses phase III results from the POLO trial, which explored the question of whether maintenance olaparib could improve overall and progression-free survival for patients with germline BRCA-mutated metastatic pancreatic cancer (Abstract 378).
Kai-Keen Shiu, MD, PhD, of the University College Hospital NHS Foundation Trust - London, discusses an interim analysis of PFS 2 results (defined as time from random assignment to progression on the next line of therapy or death) from the phase III KEYNOTE-177 trial. This study has already shown that first-line pembrolizumab provides a clinically meaningful and statistically significant improvement in PFS compared with chemotherapy in patients with microsatellite instability–high metastatic colorectal cancer (Abstract 6).
