Surgical management of patients with distant metastasized adenoid cystic carcinoma of the head and neck.

BACKGROUND: Adenoid cystic carcinoma (ACC) is a rare and malignant tumor of the salivary glands. Despite its slow-growing nature, this clinical entity is notorious for presenting with distant metastasis (DM) which significantly worsens patient outcomes. The role of surgery in patients with ACC and distant metastasis (DM) remains controversial. METHODS: We conducted a retrospective analysis of 47 patients with ACC who underwent surgery for the primary tumor and presented with DM at baseline or developed DM during follow-up. We compared survival outcomes between patients with DM at baseline (Group A) and those who developed DM during follow-up (Group B). RESULTS: The median overall survival (OS) for the entire cohort was 88%. Patients with DM at baseline (Group A) had significantly worse OS (51%) compared to those without DM at baseline (Group B) (91%; P = .04). Local recurrence (LR) was associated with poor survival in both groups. However, salvage surgery for LR+DM was associated with improved OS compared to palliative treatment (100% vs 77%; P = .79). CONCLUSION: Our findings suggest that surgery for the primary tumor of ACC may provide survival benefits in patients with DM. Salvage surgery should be considered particularly for patients who develop local recurrence and distant metastasis during follow-up.

A prospective health economic evaluation to determine the productivity loss due to premature mortality from oral cancer in India.

INTRODUCTION: India contributes two-thirds of the global mortality due to oral cancer and has a younger population at risk. The societal costs of this premature mortality are barely discussed. METHODS: Using the human capital approach, we aimed to estimate the productivity lost due to premature mortality, valued using individual socioeconomic data, related to oral cancer in India. A bottom-up approach was used to prospectively collect data of 100 consecutive patients with oral cancer treated between 2019 and 2020, with a follow-up of 36 months. RESULTS: The disease-specific survival for early and advanced stage was 85% and 70%, with a median age of 47 years. With 671 years lost prematurely, the loss of productivity was $41 900/early and $96 044/advanced stage. Based on population level rates, the total cost of premature mortality was $5.6 billion, representing 0.18% of GDP. CONCLUSION: India needs to implement tailored strategies to reduce the economic burden from premature mortality.
