Ca19.9 positivity and doubling time are prognostic factors of mortality in patients with advanced medullary thyroid cancer with no evidence of structural disease progression according to RECIST.

CONCLUSIONS: Serum Ca19.9 positivity and DTs <6 months and < 1 year are prognostic factors for mortality but not for PD. Serum Ca19.9 positivity and DTs <6 months and < 1 year should be considered in the decision-making process of whether to initiate systemic therapy even if there is no evidence of PD according to RECIST.  .
