ICD-10: C04

The management of malignant neoplasms of the floor of the mouth, classified under ICD-10 code C04, typically involves a multidisciplinary approach that includes surgery, radiation therapy, and chemotherapy. This comprehensive treatment strategy is tailored to the individual patient's condition, the stage of cancer, and overall health. Below, we explore the standard treatment modalities for this type of cancer.

Surgical Treatment

1. Surgical Resection

Surgery is often the primary treatment for malignant neoplasms of the floor of the mouth. The goal is to remove the tumor along with a margin of healthy tissue to ensure complete excision. The extent of surgery can vary:
- Partial Glossectomy: Removal of part of the tongue if the tumor extends to this area.
- Mandibulectomy: In cases where the cancer invades the mandible (lower jaw), a portion of the mandible may be removed.
- Neck Dissection: If there is a risk of lymph node involvement, a neck dissection may be performed to remove affected lymph nodes.

2. Reconstructive Surgery

Post-surgical reconstruction may be necessary to restore function and aesthetics, especially if significant tissue is removed. Techniques may include:
- Free Flap Reconstruction: Using tissue from another part of the body to reconstruct the floor of the mouth.
- Local Flaps: Moving nearby tissue to cover the surgical site.

Radiation Therapy

1. Adjuvant Radiation Therapy

Radiation therapy is often used post-surgery to eliminate any remaining cancer cells, particularly in cases where the tumor is large or has spread to lymph nodes. Techniques include:
- External Beam Radiation Therapy (EBRT): This is the most common form, targeting the tumor site and surrounding areas.
- Intensity-Modulated Radiation Therapy (IMRT): A more advanced form of EBRT that allows for precise targeting of the tumor while sparing healthy tissue.

2. Palliative Radiation Therapy

In advanced cases where curative treatment is not possible, radiation may be used to relieve symptoms such as pain or difficulty swallowing.

Chemotherapy

Chemotherapy may be indicated in certain cases, particularly for advanced or metastatic disease. It can be used:
- Neoadjuvantly: Before surgery to shrink the tumor.
- Adjuvantly: After surgery to reduce the risk of recurrence.
- Palliatively: To manage symptoms in advanced stages.

Common chemotherapeutic agents used for oral cancers include cisplatin, carboplatin, and 5-fluorouracil, often in combination with other drugs.

Targeted Therapy and Immunotherapy

Recent advancements in cancer treatment have introduced targeted therapies and immunotherapies, which may be considered for specific cases:
- Targeted Therapy: Drugs that specifically target cancer cell mechanisms, such as EGFR inhibitors, may be used in certain patients.
- Immunotherapy: Treatments that help the immune system recognize and attack cancer cells are being explored in clinical trials for head and neck cancers.

Multidisciplinary Care

The treatment of malignant neoplasms of the floor of the mouth typically involves a team of specialists, including:
- Oncologists: For overall cancer management.
- Surgeons: For surgical interventions.
- Radiation Oncologists: For radiation therapy planning and delivery.
- Speech and Swallowing Therapists: To assist with rehabilitation post-treatment.
