Salivary Gland Cancer Treatment
Salivary gland cancer is an uncommon malignancy that arises in the salivary glands, responsible for producing saliva for digestion and oral wellness. Although rare, early detection and sophisticated treatment modalities can ensure a favorable outcome. This article discusses the treatment of salivary gland cancer, comprising surgery, chemotherapy, immunotherapy, and targeted therapy, with fees, efficacy, and patient experience in India, China, and the USA.
About the Disease
Salivary gland cancer originates in the major (parotid, submandibular, sublingual) or minor salivary glands. Tumors can be benign or malignant, with malignant types requiring aggressive treatment. Common subtypes include mucoepidermoid carcinoma, adenoid cystic carcinoma, and acinic cell carcinoma. Symptoms may include a lump near the jaw, facial numbness, or difficulty swallowing.
Indications for Treatment
Treatment is recommended based on:
- Tumor size, location, and stage
- Cancer subtype and aggressiveness
- Patient’s overall health
- Presence of metastasis
Early-stage cancers may only require surgery, while advanced cases need multimodal therapy.
Procedure Details
Surgery
- Parotidectomy: Removal of part or all of the parotid gland.
- Submandibular gland excision: Removal of the submandibular gland.
- Neck dissection: If lymph nodes are involved.
Radiation Therapy
Used post-surgery or for inoperable tumors to destroy remaining cancer cells.
Treatment Details: Chemotherapy, Immunotherapy, and Targeted Therapy
Chemotherapy
Used for aggressive or metastatic cases. Common drugs include:
- Cisplatin
- 5-Fluorouracil (5-FU)
- Paclitaxel
Immunotherapy
Boosts the immune system to fight cancer. Drugs like Pembrolizumab (Keytruda) show promise in clinical trials.
Targeted Therapy
Focuses on specific genetic mutations. Examples:
- Larotrectinib (for NTRK gene fusion)
- Cetuximab (EGFR inhibitor)
Effectiveness
- Surgery + Radiation: 70-90% success for early-stage cancer.
- Chemotherapy/Immunotherapy: Varies; more effective in advanced cases.
- Targeted Therapy: High response rates in mutation-positive tumors.
Risks and Side Effects
- Surgery: Facial nerve damage, dry mouth.
- Radiation: Skin irritation, fatigue.
- Chemotherapy: Nausea, hair loss, immunosuppression.
- Immunotherapy: Autoimmune reactions.
Recovery and Aftercare
- Regular follow-ups to monitor recurrence.
- Physical therapy for facial muscle weakness.
- Nutritional support for dry mouth and swallowing issues.
Cost and Availability
Treatment costs vary by country and facility.

FAQ
Q: What is the survival rate for salivary gland cancer?
A: 5-year survival is ~75% for localized cases but drops if metastasized.
Q: Is immunotherapy better than chemotherapy?
A: It depends on cancer type; immunotherapy has fewer side effects but isn’t effective for all.
Q: Can salivary gland cancer recur?
A: Yes, regular monitoring is essential.
Q: What are the best hospitals in India for treatment?
A: Tata Memorial (Mumbai), AIIMS (Delhi), Apollo Hospitals.
Q: Is treatment cheaper in China than the USA?
A: Yes, costs are significantly lower in China.
Salivary gland cancer treatment has advanced with surgery, radiation, chemotherapy, and newer therapies like immunotherapy. India and China offer cost-effective options without compromising quality. Early detection remains crucial for better outcomes.
