Abstract

Anaplastic thyroid carcinoma (ATC) is a rare thyroid malignancy with a dire prognosis, nearly 100% disease specific mortality and a median overall survival less than 6 months. In view of the limited data from India on anaplastic thyroid cancer, we conducted this audit to analyze the treatment pattern, outcomes and factors influencing it. This is a retrospective analysis of outcomes of patients treated in a single institution between January 2008 and December 2020. Baseline characteristics, treatment received, and outcomes among adult patients with ATC were collected. Progression free survival (PFS) and overall survival (OS) were analyzed. SPSS version 20 and RStudio version 3.1.1 were used for analysis. In this cohort of 134 patients, the median age at diagnosis was 59 years, with 63.4% of them being females. At presentation, 70.9% of them had good performance status (PS 0-1). Only 38.8% received treatment with curative intent (either surgery fb adjuvant or neoadjuvant chemotherapy fb surgery and adjuvant or definitive chemoradiotherapy) while 61.2% patients received palliative treatment (either palliation alone or palliative chemotherapy or palliative surgery or palliative RT). Predominant pattern of progression was local progression (79.8%). Median PFS and OS of the overall cohort were 58 days and 80 days respectively. PFS and OS were significantly better in patients treated with curative intent vs palliative intent (116 and 134 days vs 45 and 50 days; p = 0.00 and 0.00 respectively). Among patients treated with curative intent, OS was significantly better in patients undergoing surgery vs CTRT (155 vs 76 days; p = 0.03). Among patients treated with upfront surgery, both PFS and OS were better with the addition of adjuvant CTRT/RT vs no adjuvant (332 and 540 days vs 55 and 91 days; p = 0.00 and 0.003 respectively). ATC is a rare cancer with dismal prognosis. Local therapy with surgery followed adjuvant seems to be associated with the better outcomes. Systemic therapy seems to be a better option for palliation. Our data reflects the real world data of this rare cancer.
