Palliative Care for Retromolar Trigone Neoplasm with Mandibular Invasion

Primary Palliative Treatment Approach

Radiotherapy is specifically indicated for inoperable tumors involving the mandible, with options including high-dose treatment between 55-70 Gy according to site, using either photon or neutron therapy 1, 2, 3
Neutron therapy alone can be considered as first-line therapy for lesions with extensive mandibular involvement where extensive disfiguring surgery would be necessary with risk of significant functional impairment 4, 5, 6
Radiotherapy is also useful for palliation of locally recurrent disease and can provide symptom relief even when cure is not achievable 1, 2, 7

Focal radiotherapy can be delivered specifically for symptomatic relief, including pain from bone invasion, bleeding, or difficulty with oral function 8
Best supportive care is a standard recommendation for advanced disease, which should include pain management with appropriate analgesics, nutritional support, management of bleeding, infection control, and psychosocial support 2, 8

When the goal is palliation rather than cure, extensive mandibular resection with significant functional impairment should generally be avoided in favor of radiotherapy-based approaches that preserve quality of life 4, 5, 6
Treatment decisions should involve multidisciplinary assessment including head and neck surgery, radiation oncology, medical oncology, and palliative care specialists to determine the most appropriate approach based on tumor extent, patient fitness, and goals of care 9
