A Comprehensive Guide to Gastric Cancer Treatments – Surgery, Chemotherapy, Radiation, Immunotherapy, and Emerging Therapies

Overview of Gastric Cancer Treatments

Gastric cancer, also known as stomach cancer, is a serious and often aggressive disease that requires timely diagnosis and appropriate treatment. There are several treatment options available for gastric cancer, depending on the stage of the disease and the overall health of the patient.

Surgery

Surgery is often the primary treatment for gastric cancer, especially in the early stages of the disease when the tumor is localized. The main goal of surgery is to remove as much of the cancerous tissue as possible, along with nearby lymph nodes to prevent the spread of cancer cells. Different surgical procedures may be performed depending on the location and size of the tumor.

Chemotherapy

Chemotherapy is a systemic treatment that uses drugs to kill cancer cells throughout the body. It is often used in combination with surgery to help shrink tumors before an operation or to destroy any remaining cancer cells after surgery. Chemotherapy may also be used as a primary treatment for advanced gastric cancer or to relieve symptoms in cases where surgery is not an option.

Radiation Therapy

Radiation therapy uses high-energy rays to target and destroy cancer cells. It can be used as a primary treatment for gastric cancer in combination with surgery or chemotherapy, or it may be used to relieve symptoms in cases where surgery is not possible. Different types of radiation therapy, such as external beam radiation or brachytherapy, may be used depending on the specific needs of the patient.

Immunotherapy and Targeted Therapy

Immunotherapy and targeted therapy are newer treatment options for gastric cancer that work in different ways than traditional chemotherapy.

How Chemotherapy Works for Gastric Cancer

In the context of gastric cancer, chemotherapy can be administered before surgery (neoadjuvant), after surgery (adjuvant), or as the primary treatment for unresectable or metastatic cases. The aim of chemotherapy is to shrink tumors, prevent cancer spread, and improve overall survival rates.

Chemotherapy drugs may be given orally or intravenously, and they work by interrupting the growth and division of cancer cells. By targeting rapidly dividing cells, chemotherapy can help reduce tumor size and control the progression of gastric cancer.

Effectiveness of Chemotherapy in Gastric Cancer

Several clinical trials and studies have demonstrated the effectiveness of chemotherapy in treating gastric cancer. For example, the MAGIC trial showed that a combination of chemotherapy drugs (epirubicin, cisplatin, and 5-fluorouracil) as neoadjuvant therapy significantly improved survival outcomes for patients with operable gastric cancer.

Furthermore, a meta-analysis published in the British Journal of Cancer found that adjuvant chemotherapy after surgery for gastric cancer reduced the risk of cancer recurrence and improved overall survival rates compared to surgery alone.

Side Effects of Chemotherapy

While chemotherapy can be a powerful tool against gastric cancer, it also comes with potential side effects. Common side effects of chemotherapy may include nausea, vomiting, fatigue, hair loss, and lowered blood cell counts. However, advancements in supportive care and targeted therapies have helped mitigate these side effects and improve the overall tolerability of chemotherapy.

Future Directions in Chemotherapy for Gastric Cancer

Researchers are continuously exploring new chemotherapy regimens, targeted therapies, and immunotherapy approaches to enhance the efficacy of treatment for gastric cancer.
