Surgery remains a cornerstone for treating gastric adenocarcinoma and many gastrointestinal cancer treatment options. Techniques span from traditional open surgery to advanced minimally invasive approaches including laparoscopic and robotic-assisted surgeries. These methods offer benefits such as less pain, fewer complications, faster recovery, and shorter hospital stays.

Common procedures in stomach cancer include endoscopic mucosal resection for early tumors, subtotal gastrectomy or total gastrectomy to remove part or all of the stomach, often with lymph node removal. Surgeons may also perform complex reconstructions like gastrojejunostomy to bypass blockages. Robotic surgery enhances precision and visibility for complex cases.

What Chemotherapy and Targeted Therapies Are Used?

Systemic chemotherapy remains a fundamental treatment. Regimens like FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) are standard for resectable gastric cancer, improving survival outcomes, as highlighted in current treatment for gastric cancer.

Targeted agents are increasingly integrated, addressing specific cancer markers. For HER2-positive cancers, trastuzumab and fam-trastuzumab deruxtecan show improved efficacy. VEGF inhibitors like ramucirumab inhibit tumor blood vessel growth. Emerging targets include CLDN18.2 as a therapeutic target, with zolbetuximab representing promising new therapy.

How Is Radiation Therapy Being Enhanced?

Modern radiation therapy employs techniques such as intensity-modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT or SABR). These techniques deliver high-dose radiation precisely to tumors while sparing healthy tissues to reduce side effects.

Radiotherapy is used before or after surgery or combined with chemotherapy to enhance treatment effects, especially in anal and gastric cancers, as described in radiotherapy combined with chemotherapy for anal cancer.

What Role Does Immunotherapy Play and How Are Biomarkers Guiding Treatment?

Immunotherapy activates the patient's immune system to target cancer cells. Immune checkpoint inhibitors like pembrolizumab and nivolumab target PD-1/PD-L1 pathways and show significant benefits in gastric cancers that express biomarkers such as MSI-high, PD-L1, or dMMR.

Molecular profiling is essential to identify these biomarkers and personalize treatment. Combining immunotherapy with chemotherapy or targeted agents is an evolving standard that improves response and survival.

Ongoing research and clinical trials are exploring novel agents and combinations to further advance patient outcomes in gastric and GI cancers.
