2. Radiation Therapy

Radiation therapy is frequently used in conjunction with surgery or as a standalone treatment, particularly in cases where:

• Tumors are inoperable: If the tumor's location makes surgical removal difficult, radiation can help shrink the tumor.
• Adjuvant Therapy: Post-surgical radiation may be recommended to eliminate any remaining cancer cells, especially if the tumor was large or had spread to lymph nodes.

Types of Radiation Therapy:
- External Beam Radiation Therapy (EBRT): This is the most common form, where high-energy beams are directed at the tumor.
- Brachytherapy: In some cases, radioactive sources may be placed directly within or near the tumor.

3. Chemotherapy

Chemotherapy may be utilized in specific scenarios, such as:

• Advanced Disease: For patients with metastatic disease or those who are not candidates for surgery.
• Neoadjuvant Therapy: Chemotherapy may be given before surgery to reduce tumor size.
• Adjuvant Therapy: Similar to radiation, chemotherapy can be administered after surgery to decrease the risk of recurrence.

4. Targeted Therapy and Immunotherapy

Recent advancements in cancer treatment have introduced targeted therapies and immunotherapies, which may be applicable depending on the tumor's specific characteristics:

• Targeted Therapy: Drugs that specifically target cancer cell pathways may be used, particularly if genetic mutations are present.
• Immunotherapy: Treatments that enhance the body’s immune response against cancer cells, such as checkpoint inhibitors, are being explored for oral cancers.

5. Supportive Care

Supportive care is crucial throughout the treatment process to manage symptoms and improve quality of life. This may include:

• Nutritional Support: Patients may require dietary modifications or supplements, especially if swallowing is affected.
• Pain Management: Effective pain control is essential for patient comfort during treatment.

Conclusion

The treatment of malignant neoplasms of overlapping sites of the mouth (ICD-10 code C06.89) requires a comprehensive and individualized approach, often involving surgery, radiation, and chemotherapy, along with supportive care. The choice of treatment depends on various factors, including the tumor's size, location, and stage, as well as the patient's overall health.
