Modern surgical techniques offer precise solutions for gastric-related issues. These procedures are tailored to the stage and location of the tumor, ensuring the best possible outcomes. Below, we explore the key surgical options available today. What is Stomach Cancer treated? Treatment Info
Endoscopic Mucosal Resection
Endoscopic mucosal resection (EMR) is a minimally invasive procedure used for early-stage tumors. It involves removing abnormal tissue through the digestive tract, preserving the stomach’s structure and function. This approach is ideal for Stage 0 or early Stage 1 cases.
Partial and Total Gastrectomy
Partial gastrectomy removes the lower two-thirds of the stomach, often preserving the spleen. This maintains partial digestive function while targeting the tumor. For advanced cases, total gastrectomy involves the removal entire stomach, with the esophagus connected directly to the small intestine. Long-term nutritional management is essential after this surgery.
Lymph Node Removal
Lymph node dissection is critical for accurate staging and reducing the risk of cancer spread. Surgeons typically remove 15 or more nearby lymph nodes to improve pathological assessment and outcomes. This step is often combined with other surgical procedures.
| Procedure | Key Details |
|---|---|
| Endoscopic Mucosal Resection | Non-invasive, preserves stomach function, ideal for early stages. |
| Partial Gastrectomy | Removes lower stomach, maintains partial digestion. |
| Total Gastrectomy | Removes entire stomach, requires reconstruction. |
| Lymph Node Dissection | Removes 15+ nodes, reduces metastatic risk. |
Radiation Therapy for Stomach Cancer
Radiation therapy plays a critical role in managing gastric-related conditions. It uses high-energy beams to target and destroy abnormal cells. This method is often combined with other treatments like surgery or chemotherapy for better results.
A care team of specialists determines the best approach based on the tumor’s location and stage. Radiation can be used before surgery to shrink the tumor or after to eliminate remaining cells. It also helps manage symptoms in advanced cases.
External Beam Radiation Therapy
External beam radiation is a common technique. It delivers radiation from outside the body directly to the tumor and nearby lymph nodes. Treatments are typically scheduled daily over five to six weeks.
Side effects may include fatigue and skin irritation. However, these are usually manageable with proper care. This method is effective in reducing the risk of cancer spread.
Intensity-Modulated Radiation Therapy
IMRT is a more advanced form of radiation therapy. It uses 3D mapping to precisely target the tumor while sparing healthy organs. Adjustable beam intensities allow for greater accuracy.
This technique reduces damage to the heart and lungs, making it safer for patients. IMRT is often used in combination with chemotherapy for enhanced results.
Radiation therapy also has palliative benefits. It can control bleeding tumors and relieve obstructive symptoms, improving quality of life for patients with advanced conditions.
Chemotherapy in Stomach Cancer Treatment
Chemotherapy is a cornerstone in managing gastric-related conditions, offering both curative and palliative benefits. It uses powerful drugs to target and destroy cancer cells, often in combination with other therapies. The approach depends on the stage of the disease and the patient’s overall health.
A care team of specialists tailors the treatment plan to maximize effectiveness. Chemotherapy can be administered before or after surgery, depending on the tumor’s characteristics. This flexibility makes it a versatile tool in modern oncology.
Neoadjuvant and Adjuvant Chemotherapy
Neoadjuvant chemotherapy is used before surgery to shrink the tumor. This increases the chances of complete removal during surgery. A standard protocol involves 3-4 cycles, each lasting 2-3 weeks. What is Stomach Cancer treated? Treatment Info
Adjuvant chemotherapy begins 4-8 weeks after surgery. It targets any remaining cancer cells to prevent recurrence. This phase typically lasts six months, ensuring thorough treatment.
Common Chemotherapy Drugs
Several drug classes are used in chemotherapy regimens. Platinum agents like cisplatin and oxaliplatin are effective in disrupting cell growth. Fluoropyrimidines, such as 5-FU and capecitabine, are often combined with other drugs for enhanced results.
