Abstract

Purpose

To describe the experience with radioiodine-resistant differentiated thyroid cancer (RR-DTC) patients treated with lenvatinib in two university hospitals from Argentina.

Methods

Adult patients with a diagnosis of RR-DTC treated with lenvatinib from April 2017 to February 2020 were registered into a retrospective database. Primary objectives were assessment of progression-free survival (PFS) and tumor response evaluated according to RECIST v 1.1. Adverse events (AEs) were evaluated by using Common Terminology Criteria for Adverse Events v5.0.

Results

Twenty-two patients were treated with lenvatinib, 13 of whom had previously received one or more multikinase inhibitors. Median duration of treatment was 7.1 months (2.2–24). Best overall response was complete response in one patient (4.5%), partial response in seven (31.8%), stable disease in seven (31.8%), and progressive disease in six (27.3%). Median PFS was 13.7 months (95% CI 3.2–24.2). All patients experienced at least one AE. Grade ≥3 AEs were observed in eight (36.4%) patients. Hypertension was the most frequent AE (63.6%) and the most common grade ≥3 AE (22.7%). Definitive withdrawal was necessary in two patients due to recurrent proteinuria (9%).

Conclusions

Tumor responses and PFS in our study were in line with other real-life clinical data and they seem to be inferior to the reported in the SELECT trial, probably related to the higher number of patients with prior MKI therapy, comorbidities, and poor performance status. Although virtually all patients experienced AEs, most of them were manageable and rarely a definitive withdrawal was necessary.
