0.75 CE/CME credit

Question 1/5
In 2020, approximately how many gastric cancer deaths were there worldwide?

In 2020, with an estimated 769,000 deaths, gastric cancer represented one of the most common causes of cancer death worldwide. Lung cancer was the leading cause of cancer death, followed by colorectal, liver, gastric and female breast cancers.

Reference

Sung H, et al. CA Cancer J Clin. 2021;71:209–49.

Question 2/5
Your patient has HER2 negative advanced gastric cancer with a PD-L1 CPS score of 8. According to the 2023 NCCN guidelines, which therapy could you consider initiating as first-line therapy?

CAPOX, capecitabine-oxaliplatin; CPS, combined positive score; FOLFOX, folinic acid, fluorouracil and oxaliplatin; HER2, human epidermal growth factor receptor 2; NCCN, National Comprehensive Cancer Network; PD-L1, programmed death-ligand 1.

The 2023 NCCN gastric cancer guidelines recommend that, for patients with HER2 overexpression negative advanced gastric cancer with a PD-L1 CPS score of ≥5, the immunotherapy that should be used is nivolumab combined with a fluoropyrimidine and oxaliplatin. The recommendation is category 1, which is defined by the NCCN as follows: Based upon high-level evidence, there is uniform NCCN consensus that the intervention is appropriate.

Abbreviations

CPS, combined positive score; HER2, human epidermal growth factor receptor 2; NCCN, National Comprehensive Cancer Network; PD-L1, programmed death-ligand 1.

Reference

Question 3/5
You are talking to a patient with gastric adenocarcinoma about the recent GLOW clinical trial. How would you describe the targeted action of zolbetuximab?

CLDN18.2, claudin 18.2; FGFR2b, fibroblast growth factor receptor 2b; HER2, human epidermal growth factor receptor 2; PD-L1, programmed death-ligand 1.

CLDN18.2 has emerged as a promising targetable biomarker. Zolbetuximab is a chimeric IgG1 monoclonal antibody that specifically binds to CLDN18.2 and mediates cell death through antibody-dependent cellular cytotoxicity and complement-dependent cytotoxicity.

Abbreviations

CLDN18.2, claudin 18.2; IgG1, immunoglobulin G1. 

Reference

Shah MA et al. J Clin Oncol. 2020;38:TPS4648.

Question 4/5
Which splice variant of FGFR does the bemarituzumab antibody specifically bind to?

FGFR, fibroblast growth factor receptor.

Bemarituzumab is an anti-FGFR2b antibody specific to the FGFR2b splice variant, which leads to inhibition of FGF ligand binding, receptor internalization/degradation and antibody-dependent cell-mediated cytotoxicity.

Abbreviations

FGF, fibroblast growth factor; FGFR, fibroblast growth factor receptor.

Reference

Catenacci DV, et al. Future Oncol. 2019;15:2073–82.

Question 5/5
Your 49-year-old male patient has been newly diagnosed with advanced gastric adenocarcinoma. According to the NCCN 2023 guidelines, which of the following biomarkers would you test for via immunohistochemistry?

CPS, combined positive score; dMMR, mismatch repair-deficient; HER2, human epidermal growth factor receptor 2; NCCN, National Comprehensive Cancer Network; NTRK, neurotrophic tyrosine receptor kinase; PD-L1, programmed death-ligand 1; TMB, tumour mutational burden.

The 2023 NCCN guidelines for gastric cancer recommend that, for patients with inoperable locally advanced, recurrent, or metastatic adenocarcinoma of the stomach, assessment for tumour HER2 overexpression using immunohistochemistry is carried out. The guidelines also recommend that MMR testing by immunohistochemistry is carried out on all newly diagnosed gastric cancers, and loss of nuclear expression of one or more MMR proteins is evidence of dMMR. PD-L1 testing may be considered on locally advanced, recurrent, or metastatic gastric carcinomas in patients who are candidates for treatment with PD-1 inhibitors via immunohistochemistry. 

Abbreviations

HER2, human epidermal growth factor receptor 2; dMMR, MMR-deficient; MMR, mismatch repair; NCCN, National Comprehensive Cancer Network; PD-L1, programmed death-ligand 1.
