Surgical Interventions: The Cornerstone of GI Cancer Treatment

Types of Surgeries for Stomach, Colorectal, and Other GI Cancers

Surgery remains a primary treatment for many gastrointestinal (GI) cancers, including stomach, colorectal, esophageal, pancreatic, and liver cancers. Common surgical procedures vary by cancer type and stage:

• Stomach Cancer: Partial (distal) gastrectomy, subtotal gastrectomy, total gastrectomy, and endoscopic mucosal resection for early tumors.
• Colorectal Cancer: Segmental colectomy or rectal resection tailored to tumor location.
• Other GI Cancers: Pancreaticoduodenectomy (Whipple procedure) for pancreatic cancer, liver resection for hepatocellular carcinoma.

Minimally Invasive Techniques Including Robotic Surgery

Advancements in surgical methods have introduced minimally invasive approaches, such as laparoscopic and robotic-assisted surgeries. These techniques offer:

• Reduced postoperative pain and quicker recovery.
• Shorter hospital stays and fewer complications.
• Enhanced precision through 3D visualization and improved dexterity with robotic tools. Robotic gastrectomy and laparoscopic colectomy are increasingly utilized at specialized centers.

Role of Lymph Node Removal and Staging

Lymphadenectomy is crucial during GI cancer surgeries to:

• Accurately stage the cancer by assessing lymph node involvement.
• Reduce the risk of cancer spread by removing affected nodes. For stomach cancer, surgeons typically remove more than 15 lymph nodes to ensure accurate staging and optimal local control (Stomach cancer surgery options).

Palliative Surgical Procedures

In advanced or unresectable GI cancers, palliative surgeries help relieve symptoms:

• Endoluminal stent placement to unblock tumor-induced obstructions.
• Gastrojejunostomy to bypass gastric outlet obstruction, facilitating food passage.
• Laser therapy to open blocked digestive pathways. These approaches improve quality of life and nutritional intake without aiming for cure.

Postoperative Management and Nutritional Considerations

Post-surgery, patients often require tailored nutritional support, especially after stomach resections:

• Smaller, frequent meals and vitamin supplementation compensate for altered digestion.
• Feeding tubes may be necessary in selected cases.
• Multidisciplinary care involving dietitians optimizes recovery and long-term health (Comprehensive stomach cancer care).

Surgical intervention remains foundational in GI cancer treatment, integrating curative, palliative, and supportive strategies to improve patient outcomes.

Systemic Therapies: Chemotherapy, Targeted Therapy, and Immunotherapy

Chemotherapy regimens including neoadjuvant and adjuvant use

Chemotherapy is integral in stomach cancer treatment and can be administered before surgery (neoadjuvant chemotherapy ) to shrink tumors or after surgery (adjuvant chemotherapy to eliminate residual cancer cells. Common chemotherapy drugs include capecitabine chemotherapy, cisplatin treatment for stomach cancer, docetaxel chemotherapy, oxaliplatin chemotherapy, fluorouracil (5-FU) chemotherapy, and paclitaxel use in stomach cancer. Hyperthermic intraperitoneal chemotherapy (HIPEC) is an advanced approach where heated chemotherapy is applied directly into the abdominal cavity post-surgery to target cancer cells in the peritoneum. This modality is being studied for improved outcomes.

Targeted therapies and their molecular targets

Targeted therapies focus on specific molecules crucial for cancer growth. Trastuzumab targeted therapy and trastuzumab deruxtecan drug target HER2-positive gastric tumors, improving survival. Ramucirumab in targeted therapy and regorafenib treatment inhibit tumor angiogenesis by targeting VEGF pathways. Zolbetuximab therapy is a novel agent targeting Claudin18.2, a protein expressed in certain gastric cancers. These therapies are selected based on molecular profiling, which also guides eligibility for clinical trials.

Immune checkpoint inhibitors and emerging immunotherapies

Immune checkpoint inhibitors such as nivolumab immunotherapy and pembrolizumab treatment have expanded treatment options by enhancing the immune system's ability to fight cancer. Their efficacy is higher in tumors expressing PD-L1, microsatellite instability-high (MSI-H), or deficient mismatch repair (dMMR) profiles, as described in immunotherapy in gastrointestinal cancers. Emerging immunotherapies include dual checkpoint blockade, adoptive cell therapies like claudin18.2-directed CAR-T cells, and oncolytic virus therapies currently under clinical investigation (Immunotherapy in gastrointestinal cancers).

Combination therapy approaches

Combining immunotherapy with chemotherapy or targeted agents has demonstrated improved outcomes, as seen in clinical trials incorporating nivolumab with standard chemotherapy regimens. Such multimodal approaches can enhance tumor response and survival in advanced gastric cancer. Moreover, perioperative immunotherapy combined with chemotherapy is showing promise in increasing pathological complete response rates.

Current challenges and future directions

Challenges include tumor heterogeneity, immune evasion mechanisms, and identifying reliable biomarkers to predict treatment response. Future research focuses on overcoming resistance through combination strategies, personalizing therapies based on molecular and immune profiling, and integrating novel agents such as bispecific antibodies, cancer vaccines, and antibody-drug conjugates. Clinical trials remain pivotal in exploring these frontiers to improve survival and quality of life for patients with gastrointestinal cancers (New Frontiers in Treating GI Cancers).

Advanced Diagnostics and Molecular Profiling: Precision in GI Cancer Management

Molecular and Genetic Profiling Techniques

Modern gastrointestinal (GI) cancer management relies heavily on molecular diagnostics for cancer. Techniques such as next-generation sequencing (NGS) analyze tumor DNA and RNA to identify specific genetic alterations and mutations that drive cancer growth. Patient-derived organoids and high-throughput genetic screens further enable testing drug responses tailored to individual tumors.

Biomarker Identification for Therapy Selection

Biomarkers play a crucial role in guiding treatment decisions. Key markers include microsatellite instability-high (MSI-H), PD-L1 expression, HER2 status, and gene mutations such as KRAS or BRAF. These biomarkers help select targeted therapies, immunotherapies, and chemotherapy regimens best suited to each patient's tumor profile.

Role of Imaging and Artificial Intelligence

Advanced imaging methods, enhanced by artificial intelligence (AI), improve detection and characterization of GI tumors. AI-assisted endoscopy and CT scans detect subtle lesions, assess tumor response to therapy, and assist in precise staging. AI-based digital pathology and molecular twin platforms aid in predicting treatment outcomes and survival.

Importance of Early Detection and ctDNA Monitoring

Early detection is vital as many GI cancers are asymptomatic initially. Circulating tumor DNA (ctDNA) blood tests provide a non-invasive option to detect minimal residual disease, monitor treatment response, and identify recurrences earlier than imaging alone.

Facilitating Personalized Treatment and Clinical Trial Eligibility

Precision diagnostics enable clinicians to tailor therapies based on molecular findings, optimize combination treatments, and identify eligibility for novel clinical trials. This personalized approach is revolutionizing care and improving outcomes for GI cancer patients.
