Clinical Trial Summary

This is a prospective, observational, multi-center study examining the long-term outcomes of patients with small, low risk papillary thyroid cancer who offered the choice of active surveillance (close follow-up to monitor for potential disease progression) or immediate surgery.

Clinical Trial Description

This is a prospective, observational multi-center study, building on an initial single-centre study from Toronto, Canada (ClinicalTrials.gov Identifier: NCT03271892). Adult patients with small, low-risk papillary thyroid cancer may choose either active surveillance (close follow-up with the intention of surgery if the disease progresses or if the patient changes their mind and wants surgery) or immediate thyroid surgery (thyroidectomy). Patients who choose active surveillance are clinically followed at the participating study centre and those who choose surgery, receive usual care from their treating surgeon and/or other thyroid cancer specialists.

Thyroid cancer clinical and treatment outcomes are tracked (by medical record review) at least yearly for up to 10 years after enrollment. Patients are also asked to complete study questionnaires (patient reported outcomes) yearly for up to 5 years.

The underlying assumption in the study is that since patients' disease management goals differ for individuals choosing active surveillance and those choosing surgery, 'successful' disease management is defined differently for these patient groups. For patients choosing active surveillance, successful disease management may be defined by avoiding thyroid surgery for thyroid cancer progression (i.e. thyroid cancer that has grown or spread to other tissues). For patients choosing surgery, the ultimate goal is cure of the thyroid cancer (i.e. no thyroid cancer detected at long-term follow-up).

The primary analysis in this study is a description of how often patients' initial disease management goals are not achieved at long-term follow-up. For this study, 'failure' of disease management is defined as follows: a) in active surveillance group - surgery for disease progression, and b) in the immediate surgery group - requiring additional treatment for persistent or recurrent thyroid cancer (i.e. thyroid cancer that is detected and treated in follow-up). Thyroid cancer clinical and treatment outcomes as well as patient questionnaire outcomes will be reported. ;
