What are the treatment options for salivary gland cancer?

Treatment for salivary gland cancer is primarily based on a combination of surgery, radiation therapy, and in some cases, chemotherapy. There is no single treatment plan that fits everyone; a multidisciplinary team specializing in head and neck oncology determines the most appropriate protocol based on the stage of the cancer, microscopic cell type, tumor size, the location of the affected gland (such as the parotid, submandibular, or sublingual glands), and the patient's overall health status [1].

Surgery as a Primary Intervention

Surgery is considered the cornerstone of treatment for most salivary gland tumor cases. The surgical procedure aims to completely remove the tumor, while preserving vital nerves and surrounding tissues as much as possible. In cases where the tumor is diagnosed as malignant, the extent of the surgery may be expanded to remove adjacent affected tissues [2]. If an accurate diagnosis cannot be made via fine-needle aspiration (FNA), exploratory surgery may be the only way to reach a definitive diagnosis through laboratory examination of the removed tissue [1].

Radiation Therapy and Implications

Radiation therapy is used as an adjuvant option after surgery to reduce the risk of tumor recurrence, especially if there are concerns about residual cells or in advanced stages. This technique relies on directing high-energy beams to kill cancer cells [1]. It is essential for patients to understand that radiation in the head and neck area may lead to side effects such as chronic dry mouth, which requires preventive strategies like drinking plenty of fluids, using saliva substitutes, and maintaining oral hygiene to avoid tooth decay and gum infections [2].

Chemotherapy and Managing Side Effects

Chemotherapy is usually reserved for advanced cases or instances where the cancer has spread to other organs (metastatic cancer). The treatment works through drugs that target rapidly dividing cells [1]. Because these drugs also affect healthy cells, patients may suffer from mouth sores, digestive disturbances, severe fatigue, and a temporary decrease in immunity. Supportive care involves strict adherence to oral hygiene using a soft brush and avoiding alcohol-based mouthwashes [3].

Recovery Expectations and Follow-up

Recovery is an individual process that depends on how the body responds to the treatment protocol. Patients must strictly adhere to periodic follow-up appointments, as there is a possibility of cancer recurrence in the glands or other areas [1]. Recovery after chemotherapy or radiation requires additional caution regarding infection, such as avoiding undercooked foods, washing hands regularly, and staying away from crowded gatherings during periods when the immune system is weak [3]. If symptoms such as persistent fever, shortness of breath, or unexplained swelling appear, you should contact the medical team immediately [3].
