What Are the Treatments Available for Oral Cancer?

Oral cancer is a serious medical condition that affects thousands of people worldwide. It can develop in various parts of the mouth, including the lips, tongue, gums, and the lining of the cheeks. The treatment for oral cancer depends on factors such as the stage of the cancer, its location, and the overall health of the patient. Traditional treatment for oral cancer in Nepal include surgery, radiation therapy, and chemotherapy. However, there are also emerging and innovative treatments that offer new hope for patients diagnosed with this disease.

I. Treatment Options for Oral Cancer:

A. Surgery 

• Types of surgical procedures
  • Resection: This surgical procedure involves removing the tumor along with a margin of healthy tissue. It is often the primary treatment for localized oral cancer.
  • Neck dissection: When oral cancer has spread to the lymph nodes in the neck, a neck dissection may be performed to remove these affected lymph nodes.
• Goals and outcomes
  • The primary goal of surgery is to remove the cancerous tissue and potentially affected lymph nodes to prevent the spread of the disease.
  • Outcomes depend on the stage and extent of the cancer, but surgery can often lead to a complete cure for early-stage oral cancers.
  • Cosmetic and functional outcomes are also considered, with efforts made to preserve speech, swallowing, and appearance.

B. Radiation Therapy 

• External beam radiation
  • External beam radiation therapy involves the use of a machine that directs high-energy beams of radiation at the cancerous cells. It is commonly used in conjunction with surgery or alone in cases where surgery is not possible.
  • This treatment is usually administered daily over several weeks.
• Brachytherapy
  • Brachytherapy is a form of radiation therapy where radioactive material is placed directly inside or very close to the tumor. It is often used for small tumors or to boost the effects of external beam radiation.
• Side effects and management
  • Side effects of radiation therapy may include fatigue, skin changes, difficulty swallowing, and mouth sores.
  • Management of side effects typically involves medications to alleviate symptoms, dietary modifications, and lifestyle adjustments.

C. Chemotherapy 

• Systemic chemotherapy
  • Systemic chemotherapy involves the use of drugs that circulate throughout the body to kill cancer cells. It is typically used when oral cancer has spread to other parts of the body or in conjunction with radiation therapy for certain cases.
  • It is administered through an IV or orally.
• Targeted therapy
  • Targeted therapy focuses on specific molecules or pathways involved in cancer growth. It is a more precise approach compared to traditional chemotherapy.
  • Targeted therapies may have fewer side effects than traditional chemotherapy.
• Side effects and considerations
  • Side effects of chemotherapy can include nausea, vomiting, hair loss, fatigue, and an increased risk of infection.
  • Careful monitoring and supportive care are essential to manage side effects and ensure the patient’s overall well-being during treatment.

II. Multidisciplinary Approaches 

A. Combined modality treatments 

One of the most effective ways to treat oral cancer is through combined modality treatments. This approach combines different types of therapies, such as surgery, radiation therapy, and chemotherapy, to target the cancer from multiple angles. Combined modality treatments can help increase the chances of successful tumor removal and reduce the risk of cancer recurrence.

• Surgery: Surgery is often the primary treatment for oral cancer. Surgeons remove the tumor and surrounding tissues to ensure that no cancer cells are left behind. Depending on the extent of the cancer, surgery may involve removing a portion of the tongue, jawbone, or other affected areas. Reconstructive surgery may also be necessary to restore function and appearance.
• Radiation Therapy: Radiation therapy uses high-energy X-rays or other forms of radiation to target and destroy cancer cells. It is often used in conjunction with surgery to kill any remaining cancer cells or as a primary treatment for patients who cannot undergo surgery. Radiation oncologists specialize in planning and administering radiation therapy.
• Chemotherapy: Chemotherapy involves the use of drugs to kill cancer cells or stop their growth. Medical oncologists are responsible for administering chemotherapy treatments. Chemotherapy can be given before surgery (neoadjuvant), after surgery (adjuvant), or in combination with radiation therapy, depending on the specific case.

B. Role of medical oncologists, radiation oncologists, and surgeons in treatment planning 

The successful treatment of oral cancer relies on the expertise of various specialists, each playing a crucial role in treatment planning and execution.

• Medical Oncologists: Medical oncologists are physicians who specialize in the use of chemotherapy and other systemic treatments for cancer. They assess the patient’s overall health and recommend appropriate chemotherapy regimens. They monitor the patient’s response to treatment and manage any side effects.
• Radiation Oncologists: Radiation oncologists are responsible for designing and delivering radiation therapy plans. They work closely with the medical team to ensure that the radiation is targeted accurately and that the treatment is both effective and safe. They also manage any radiation-related side effects.
• Surgeons: Surgeons, including maxillofacial surgeons and head and neck surgeons, perform the surgical removal of oral cancer tumors. They play a critical role in the initial diagnosis, staging, and planning of the surgical procedure. Surgeons also perform reconstructive surgery to restore function and appearance after tumor removal.

C. Personalized treatment plans

Every patient’s oral cancer is unique, and treatment plans must be tailored to individual needs. Personalized treatment plans take into account factors such as the stage and location of the cancer, the patient’s overall health, and their preferences. A multidisciplinary team of healthcare professionals collaborates to create a treatment plan that offers the best chance of success while minimizing side effects and preserving quality of life.

III. Emerging and Innovative Treatments 

A. Immunotherapy: 

Immunotherapy is a cutting-edge treatment option that has shown promise in the fight against oral cancer. This approach harnesses the power of the body’s immune system to target and destroy cancer cells. Immunotherapy drugs, such as checkpoint inhibitors, work by blocking the mechanisms that prevent immune cells from recognizing and attacking cancer cells. This can lead to a more effective immune response against oral cancer. While immunotherapy is not yet a standard treatment for all oral cancer cases, ongoing research and clinical trials are exploring its potential benefits.

B. Photodynamic Therapy: 

Photodynamic therapy (PDT) is a minimally invasive treatment option for oral cancer. It involves the use of a photosensitizing agent and laser light to selectively destroy cancer cells. The photosensitizer is administered to the patient either intravenously or topically and is absorbed by the cancer cells. When exposed to laser light, the photosensitizer becomes activated and generates reactive oxygen species, which can destroy the cancer cells. PDT is less invasive than surgery and can be a valuable option for treating early-stage oral cancers and precancerous lesions.

C. Clinical Trials and Experimental Therapies: 

Clinical trials are crucial in advancing the treatment options for oral cancer. These trials test new drugs, therapies, and treatment approaches to determine their safety and efficacy. Patients who participate in clinical trials have the opportunity to access cutting-edge treatments that may not yet be widely available. Experimental therapies, such as targeted therapies and gene therapies, are continually being explored in the quest to find more effective and less invasive treatments for oral cancer.

D. Potential Benefits and Risks: 

While emerging treatments offer hope and potential advantages for oral cancer patients, it’s important to acknowledge that they also come with potential risks and uncertainties. Each patient’s case is unique, and not all individuals will be eligible for or benefit from these innovative treatments. Furthermore, the long-term effects and success rates of these treatments are still being studied. Patients considering these treatments should discuss their options thoroughly with their healthcare team and weigh the potential benefits against the risks.

IV. Rehabilitation and Supportive Care 

Oral cancer treatment can be physically and emotionally challenging, and patients often require rehabilitation and supportive care to enhance their quality of life during and after treatment. This section discusses various aspects of rehabilitation and supportive care for oral cancer patients.

A. Managing Treatment Side Effects (e.g., pain, difficulty swallowing)

• Pain Management: Oral cancer treatment in Nepal, including surgery, radiation therapy, and chemotherapy, can lead to significant pain and discomfort. Pain management strategies may include medications, nerve blocks, or alternative therapies like acupuncture.
