More men performed physical activities (34% vs 17%, P = 0.024). The frequency of smoking and alcohol consumption was higher in men (58% vs 33%, P = 0.003; 45% vs 17%, P = 0.001). We did not find sex differences in lenvatinib dose reduction due to adverse events (AEs) (78% females vs 85% males). Ninety-nine percent of patients developed at least one adverse event (AE), with no sex difference in their number and the time to first AE. Severe AEs occurred in 74% of males and 66% of females (P = 0.398), with a mean dose of 18.2 mg (±5.7), and a median time to the first serious AE of 9 weeks (1-154). Stomatitis/mucositis and hematological disorders were more frequent in females (48% vs 30%, P = 0.016; 17% vs 4%, P = 0.011). Gastrointestinal disorders were higher in males (15% vs 2%, P = 0.010). Eighty-seven patients interrupted lenvatinib due to AEs (median time: 3 months (0-48), mean dose: 17 mg ±5.5). Discontinuation occurred in 21 patients, five for severe AEs. No sex differences were found in progression-free survival, overall survival or disease control rate.
