Oral Cancer Treatment

Introduction

Oral cancer management includes multidisciplinary care that incorporates surgery, radiotherapy, chemotherapy, and targeted therapies. Early diagnosis and sophisticated treatments are now making survival possible with greatly improved rates globally. With oral cancer still a serious health issue in the likes of India and Southeast Asia, information on current treatment methods, cost, recovery, and access to clinical trials is important. The present guide is an overall overview of oral cancer management today.

About the Disease

Oral cancer refers to malignancies affecting the mouth, lips, gums, tongue, inner cheeks, roof of the mouth (hard and soft palate), and the floor of the mouth. The most common histological type is squamous cell carcinoma, accounting for over 90% of cases.

Risk Factors:

• Tobacco use (smoked and smokeless)

• Alcohol consumption

• HPV infection (especially for oropharyngeal cancers)

• Chronic irritation from ill-fitting dentures

• Poor oral hygiene

• Sun exposure (for lip cancer)

Early detection is key to successful treatment. Symptoms may include persistent mouth ulcers, difficulty swallowing, voice changes, unexplained bleeding, and jaw or tongue pain.

Indications for Treatment

Treatment depends on:

• Stage of cancer (Stage I-IV)

• Tumor location and size

• Spread to lymph nodes or distant organs

• Patient’s general health and age

• Preference and tolerance to treatment

Key Treatment Objectives:

• Eradicate the tumor

• Preserve oral function (speech, chewing, swallowing)

• Minimize cosmetic disfigurement

• Prevent recurrence

• Enhance quality of life

Treatment Details

Oral cancer treatment includes a combination of the following modalities:

1. Surgery

• Primary option for localized tumors

• Wide excision with margins

• Neck dissection if lymph nodes are involved

• Reconstruction using skin, bone, or tissue grafts

2. Radiotherapy

• Delivered as External Beam Radiotherapy (EBRT) using IMRT, IGRT

• Can be curative in early-stage cancers or adjuvant post-surgery

• Palliative use in advanced cancers

3. Chemotherapy

• Used in combination with radiation or after surgery

• Drugs like Cisplatin, 5-FU, Docetaxel, Carboplatin are commonly used

• Can be neoadjuvant (before surgery) or adjuvant (after surgery)

4. Targeted Therapy and Immunotherapy

• Cetuximab (anti-EGFR) for locally advanced or recurrent cancers

• Nivolumab, Pembrolizumab (immune checkpoint inhibitors) for metastatic disease

5. Palliative Care

• For terminal-stage patients

• Includes symptom relief (pain, bleeding, infections) and emotional support

Medicines Used

Depending on the treatment plan, the following classes of drugs may be administered:

Chemotherapy:

• Cisplatin

• 5-Fluorouracil (5-FU)

• Carboplatin

• Paclitaxel

• Docetaxel

Targeted Therapy:

• Cetuximab – Targets EGFR proteins

• Bevacizumab – Anti-angiogenic drug (less common)

Immunotherapy:

• Nivolumab, Pembrolizumab – Effective for platinum-refractory or metastatic oral cancers

Supportive Medications:

• Antiemetics, pain relievers, antibiotics, nutritional supplements

Effectiveness of Oral Cancer Treatment

The success of oral cancer treatment depends on early detection, multidisciplinary management, and patient compliance.

Survival Rates:

• Stage I-II: 70–90% 5-year survival

• Stage III-IV: 30–60% with combined modality treatment

• Recurrence risk is high without adjuvant therapy in advanced disease

Modern techniques like robot-assisted surgery and IMRT have improved outcomes with fewer side effects and better cosmetic results.

Risks and Side Effects

Each treatment modality comes with its own side effects:

Surgery:

• Facial disfigurement

• Speech and swallowing issues

• Infection or bleeding

Radiotherapy:

• Mouth sores

• Dry mouth (xerostomia)

• Taste loss

• Jaw stiffness

Chemotherapy:

• Fatigue

• Nausea, vomiting

• Low blood counts

• Mouth ulcers

Targeted Therapy/Immunotherapy:

• Skin rashes

• Diarrhea

• Immune-related adverse effects (e.g., pneumonitis, thyroiditis)

Multidisciplinary teams manage these side effects with medications, rehabilitation, and lifestyle adjustments.

Recovery and Aftercare

Recovery after oral cancer treatment is a gradual process involving:

• Wound healing (post-surgery)

• Management of oral mucositis and dry mouth

• Nutritional therapy (often via feeding tubes initially)

• Physiotherapy and speech therapy

• Dental care (to manage post-radiation effects)

• Psychological counseling and support groups

Follow-up visits are recommended every 1–3 months during the first year and gradually reduced thereafter.

Cost and Availability

The cost of oral cancer treatment varies depending on location, treatment modality, stage of cancer, and whether treatment is received in a public or private facility.

In India:

• Surgery: ₹50,000 – ₹2,50,000 (USD 600 – 3,000)

• Radiotherapy (IMRT): ₹1,00,000 – ₹2,50,000 (USD 1,200 – 3,000)

• Chemotherapy: ₹30,000 – ₹1,50,000 per cycle (USD 350 – 1,800)

• Targeted Therapy: ₹2,00,000 – ₹5,00,000 per cycle (USD 2,500 – 6,000)

Government schemes like Ayushman Bharat offer subsidized or free treatment at public hospitals.

In China:

• Surgery: ¥12,000 – ¥50,000 (USD 1,800 – 7,000)

• Radiotherapy: ¥25,000 – ¥60,000 (USD 3,000 – 8,000)

• Chemotherapy: ¥8,000 – ¥30,000 per cycle (USD 1,000 – 4,500)

• Immunotherapy: ¥30,000 – ¥90,000 per cycle (USD 4,500 – 13,000)

Top-tier hospitals in cities like Beijing, Shanghai, and Guangzhou offer world-class treatment with international protocols.

Patient Experiences

Patients often describe the treatment journey as physically and emotionally challenging but ultimately life-changing. Early-stage patients typically return to work and social life within 3–6 months, while advanced-stage patients may take longer to recover.

Key insights from survivors:

• The importance of early diagnosis

• Positive outcomes with proper nutrition and therapy

• The critical role of family and support systems

• Improvement in speech and swallowing over time

• Hope with immunotherapy in recurrent cases

China is rapidly advancing in oral cancer research. Current clinical trials focus on:

• Neoadjuvant immunotherapy before surgery for resectable tumors

• Targeted therapies combined with radiotherapy

• Proton therapy vs IMRT for better tissue preservation

• AI-guided surgical planning

• Gene expression-based prognostic models

• Fluorescence-guided tumor resection

Key institutions: Fudan University Cancer Center, Sun Yat-sen University Cancer Center, and Beijing Cancer Hospital.
