Chemotherapy can have side effects, such as nausea, fatigue, hair loss, and decreased blood cell counts. However, these side effects can often be managed with supportive care.
Radiation Therapy
Radiation therapy uses high-energy rays to target and destroy cancer cells. It can be delivered externally (external beam radiation) or internally (brachytherapy). Radiation therapy may be employed in combination with chemotherapy, particularly in cases where surgery is not an option or to help shrink the tumor before surgery.
Common types of radiation therapy for gastric cancer include:
- External Beam Radiation: Precisely targeted radiation delivered from outside the body to the tumor site.
- Brachytherapy: Internal radiation therapy where a radioactive source is placed directly into or near the tumor.
Radiation therapy can cause side effects such as skin changes, fatigue, and gastrointestinal issues. The treatment team will work to manage these side effects and ensure the best possible outcome for the patient.
According to the American Cancer Society, the combination of chemotherapy and radiation therapy can be effective in treating some types of gastric cancer, especially in cases where the tumor is unresectable.
Research and Statistics
Recent studies have shown promising results in combining chemotherapy and radiation therapy for gastric cancer. A meta-analysis published in the Journal of Clinical Oncology revealed that the addition of chemotherapy to radiation therapy improved overall survival in patients with locally advanced gastric cancer. Another study in the European Journal of Cancer indicated that neoadjuvant chemoradiotherapy resulted in tumor downsizing and increased chances of complete resection in advanced gastric cancer cases.
| Study | Outcome |
|---|---|
| Meta-analysis in Journal of Clinical Oncology | Improved overall survival in locally advanced gastric cancer |
| Study in European Journal of Cancer | Tumor downsizing and increased resection rates in advanced gastric cancer |
