Breakthrough Study Offers Hope for Gastric Cancer Treatment

Stepping into the future of gastric cancer treatment, researchers in Singapore have made a significant breakthrough, bringing new hope to patients diagnosed with peritoneal metastasis. This challenging condition, often linked with advanced gastric cancer, has seen limited treatment options and dismal survival rates. However, a recent study by the National University of Singapore (NUS) is set to change the landscape.

Gastric cancer, the fifth most common globally, hides a grim statistic as the third leading cause of cancer-related deaths, taking a toll of over a million new cases annually. In Singapore, with around 300 lives claimed each year, it ranks among the top 10 deadliest cancers. The peritoneum, the lining of the abdominal cavity, is frequently the site of metastasis in these patients, leading to a poor prognosis, often leaving survivors with a median lifespan of three to six months.

The latest breakthrough heralds from a study published in the esteemed journal ‘Gastroenterology.’ Researchers from prominent institutions like the National University Hospital (NUH), National University Cancer Institute (NCIS), Yong Loo Lin School of Medicine at NUS Medicine, National Cancer Centre Singapore (NCCS), and Duke-NUS Medical School have unlocked critical insights into the molecular pathways that allow gastric cancer to invade the peritoneum like an unfaltering tempest.

Utilizing sophisticated genomic and transcriptomic technologies, researchers carried out an exhaustive analysis of patient samples. Raghav Sundar, Associate Professor and Senior Consultant at NCIS, and the lead researcher, highlights the significance, stating, “Our research has provided a detailed roadmap of the processes that enable gastric cancer to spread to the peritoneum. This understanding is crucial for developing more targeted and effective treatments.”

Adding to these optimistic findings, the PIANO trial has unveiled a promising treatment strategy. Spearheaded by Professor Jimmy So, Senior Consultant at NUH and Professor of Surgery at NUS Medicine, this trial examined the effects of combining Pressurised Intra-Peritoneal Aerosol Chemotherapy (PIPAC) with immunotherapy. The results, shared in ‘ESMO Open,’ left the medical community optimistic. Professor So commented on the positive feedback from the trial: “The PIANO trial results show that combining targeted therapies with immunotherapy holds great promise for revolutionizing the treatment of gastric cancer peritoneal metastasis.”

This pioneering research carries the potential to transform the battle against gastric cancer through personalized treatment strategies. By identifying predictive biomarkers and therapeutic targets, this study paves the way for bespoke cancer treatment plans, tailored specifically to the patient’s cancer profile, offering a beacon of hope to those grappling with this formidable disease.
