Small Intestine Cancer Treatment
Small intestine cancer is a rare yet severe disorder of the gastrointestinal tract. While it is responsible for fewer than 1% of all gastrointestinal cancers, early treatment and diagnosis are essential to enhance survival rates. In this article, treatment modalities of small intestine cancer such as surgery, chemotherapy, immunotherapy, and targeted therapy, with an emphasis on recent developments in India and China, have been described.
About the Disease
The small intestine plays a vital role in nutrient absorption. Cancer in this region can arise from different cell types, including adenocarcinomas, sarcomas, neuroendocrine tumors, and lymphomas. Symptoms may include abdominal pain, weight loss, nausea, and blood in the stool. Due to its rarity, diagnosis is often delayed, making treatment more challenging.
Indications for Treatment
Treatment is recommended based on:
- Tumor size and location
- Cancer stage (localized or metastatic)
- Patient’s overall health
- Presence of symptoms like obstruction or bleeding
Procedure Details
Surgery
The primary treatment for localized small intestine cancer is surgical removal of the tumor. Procedures include:
- Segmental resection: Removal of the affected intestine section.
- Whipple procedure: For tumors near the pancreas.
- Lymph node dissection: To check for cancer spread.
Minimally Invasive Techniques
Laparoscopic and robotic-assisted surgeries reduce recovery time and complications.
Treatment Details
Chemotherapy
Chemotherapy uses drugs to kill cancer cells and is often used post-surgery or for advanced cases. Common drugs include:
- 5-Fluorouracil (5-FU)
- Capecitabine
- Oxaliplatin
Immunotherapy
Immunotherapy boosts the immune system to fight cancer. Drugs like Pembrolizumab (Keytruda) are used for MSI-H (microsatellite instability-high) tumors.
Targeted Therapy
Targeted drugs focus on specific cancer cell mutations:
- Bevacizumab (Avastin): Blocks blood vessel growth in tumors.
- Everolimus (Afinitor): Used for neuroendocrine tumors.
Effectiveness
- Early-stage cancer: Surgery offers a high cure rate (60-80% 5-year survival).
- Advanced cancer: Combination therapies improve survival but depend on cancer type and response.
Risks and Side Effects
- Surgery risks: Infection, bleeding, digestive issues.
- Chemotherapy side effects: Fatigue, nausea, hair loss.
- Immunotherapy risks: Autoimmune reactions (colitis, pneumonitis).
Recovery and Aftercare
- Hospital stay: 5-10 days post-surgery.
- Dietary changes: Easily digestible foods initially.
- Follow-up: Regular scans and blood tests to monitor recurrence.
Cost and Availability
Treatment costs vary by country and facility. India and China offer affordable options compared to Western countries.

Patient Experiences
Many patients report successful outcomes with early detection. Challenges include managing side effects and financial burdens, especially in high-cost countries.
