Study Details

Brief summary:

The purpose of this study is to better understand the outcomes of active surveillance (observation) instead of immediate surgery, which is the current standard of care for papillary thyroid microcarcinoma (PTMC). Patients with a 1.5 cm or smaller thyroid nodule(s) with papillary thyroid carcinoma will be eligible for the study.

Interventions and Outcome Measures

Arms

other: Active Surveillance

Active surveillance instead of standard of care immediate surgery. Patients will be closely monitored every six months until disease is stable for a two-year period and then annually thereafter.

no intervention: Immediate Surgery

Patients who choose to get surgery immediately after diagnosis may choose to enroll in a questionnaire sub-study that will compare quality of life and anxiety scores to patients who enroll in the active surveillance study. This is considered "no intervention" because the protocol is not directing treatment. Surgery is the standard treatment for papillary thyroid microcarcinoma.

Interventions

Active Surveillance

Subjects will be actively observed for disease progression (condition worsens) instead of receiving immediate surgery, considered standard of care.

Primary outcome measure

  • Rate of disease progression [ Time Frame: From time of diagnosis up to10 years of follow-up ]
