The FDA has granted Priority Review to the New Drug Application for ripretinib as treatment of patients with advanced gastrointestinal stromal tumors. This potential FDA approval has a Prescription Drug User Fee Act target action date of August 13, 2020, according to a press release from Deciphera Pharmaceuticals, Inc.<br /> &nbsp;

The incidence of colorectal cancer is rising among people who are below 50 years of age, the colonoscopy screening age as recommended by the United States Preventive Service Task Force of the National Cancer Institute. To date, there is no research that can explain the rise which has led physicians to deliberation on whether the recommended screening age for colonoscopies should be lowered or left as is. During a debate at the 2020 Gastrointestinal Cancers Symposium, Uri Ladabaum, MD, and David S. Weinberg, MD, MSc, presented their stances on the topic.

A new phase II study of trastuzumab and pertuzumab added to neoadjuvant chemoradiotherapy followed by surgery in patients with esophageal adenocarcinoma has found the combined regimen to be feasible and worthy of further study.

The combination of regorafenib plus an oral fluoropyrimidine, TAS-102, as third-line treatment in patients with metastatic colorectal cancer, achieved a clinically meaningful disease control rate in the phase I dose-escalation trial REMETY, according to data presented at the 2020 Gastrointestinal Cancers Symposium.

Joseph Chao, MD, discusses the importance of assessing the microsatellite instability (MSI) status in patients with advanced gastric/gastroesophageal junction cancer based on findings from a comparative analysis of KEYNOTE-059, KEYNOTE-061, and KEYNOTE-062.

In an interview with&nbsp;Targeted Oncology, Vincent Chung, MD, discussed the findings from the pilot trial evaluating the addition of dietary supplements to combination chemotherapy in patients with unresectable pancreatic cancer. He also highlighted the importance of these findings and the next steps necessary to evaluate the role of supplements in pancreatic cancer further.

Promising antitumor activity with durable responses were demonstrated with the combination of nivolumab and ramucirumab plus paclitaxel&nbsp;in a phase II study of patients with advanced gastric cancer, which wsa presented at the 2020 Gastrointestinal Cancers Symposium.&nbsp;Among patients treated with the combination, the objective response rate was 37.2%, and all responders had a partial response.

Overall survival was meaningfully improved with treatment of pembrolizumab in first and later lines for patients with&nbsp;advanced gastric/gastroesophageal junction cancer with a high number of PD-L1&ndash;expressing cells in the tumor, lymphocytes, and macrophages compared with chemotherapy.

A subset of patients with GI cancers harboring&nbsp;<em>NTRK</em>&nbsp;gene fusions had positive responses to selective TRK inhibition with larotrectinib, confirming efficacy of the agent in this group. The results of the confirmatory trial were recently reported the 2020 Gastrointestinal Cancers Symposium.

Hirva Mamdani, MD, explains the rationale for conducting a safety and efficacy study of durvalumab in patients following multimodality therapy for locally advanced esophageal and gastroesophageal junction adenocarcinoma.

A phase Ib/II clinical trial of the experimental anti-mitochondrial drug devimistat in combination with cisplatin and gemcitabine has been initiated in patients with biliary tract cancer, according to a press release from Rafael Pharmaceuticals, Inc.

Integrating a geriatric assessment into the care of older adults who are receiving cancer treatment in communi&shy;ty oncology practices improves patient and caregiver satisfaction and encourages commu&shy;nication about aging-related concerns, accord&shy;ing to results of a clinical trial that enrolled 541 patients with advanced cancer.

The present and future benefits of telehealth in oncology can be observed through Tahoe For&shy;est Cancer Center and its affiliation with the UC Davis Cancer Center, use of other remote clinics, and participation in virtual tumor boards. Even though there are roadblocks to telehealth reaching more locations and more patients, the potential benefit warrants the time needed to get over those hurdles.
