PurposeTo test whether the prognostic risk of male sex in papillary thyroid cancer (PTC) is determined by BRAF V600E and can thus be stratified by BRAF status.Patients and MethodsWe retrospectively investigated the relationship between male sex and clinicopathologic outcomes in PTC, particularly mortality, with respect to BRAF status in 2,638 patients (male, n = 623; female, n = 2,015) from 11 centers in six countries, with median age of 46 years (interquartile range, 35-58 years) at diagnosis and median follow-up time of 58 months (interquartile range, 26-107 months).ResultsDistant metastasis rates in men and women were not different in wild-type BRAF PTC but were different in BRAF V600E PTC: 8.9% (24 of 270) and 3.7% (30 of 817; P = .001), respectively. In wild-type BRAF PTC, mortality rates were 1.4% (five of 349) versus 0.9% (11 of 1175) in men versus women (P = .384), with a hazard ratio (HR) of 1.59 (95% CI, 0.55 to 4.57), which remained insignificant at 0.70 (95% CI, 0.23 to 2.09) after clinicopathologic multivariable adjustment. In BRAF V600E PTC, mortality rates were 6.6% (18 of 272) versus 2.9% (24 of 822) in men versus women (P = .006), with an HR of 2.43 (95% CI, 1.30 to 4.53), which remained significant at 2.74 (95% CI, 1.38 to 5.43) after multivariable adjustment. In conventional-variant PTC, male sex similarly had no effect in wild-type BRAF patients; mortality rates in BRAF V600E patients were 7.2% (16 of 221) versus 2.9% (19 of 662) in men versus women (P = .004), with an HR of 2.86 (95% CI, 1.45 to 5.67), which remained significant at 3.51 (95% CI, 1.62 to 7.63) after multivariable adjustment.ConclusionMale sex is a robust independent risk factor for PTC-specific mortality in BRAF V600E patients but not in wild-type BRAF patients. The prognostic risk of male sex in PTC can thus be stratified by BRAF status in clinical applica
