Results A total of 32 patients (21 males and 11 females) were enrolled,and all of them presented BP induced by programmed death-1/programmed death ligand-1 inhibitors.Compared with non-Chinese patients,the Chinese patients with ICI-induced BP showed low average ages [(65.2±9.5) years <i>vs.</i> (69.9±10.3) years,<i>P</i>=0.020],increased proportion of BP induced by tislelizumab (28.1% <i>vs.</i> 0,<i>P</i><0.001),decreased proportions of BP induced by pembrolizumab (18.8% <i>vs.</i> 39.4%,<i>P</i>=0.029) and nivolumab (3.1% <i>vs.</i> 52.8%,<i>P</i><0.001),and decreased proportion of primary malignant melanoma (9.4% <i>vs.</i> 43.3%,<i>P</i><0.001).The incidence of pruritus (96.9% <i>vs.</i> 66.1%,<i>P</i><0.001) and mucosal involvement (59.4% <i>vs.</i> 15.7%,<i>P</i><0.001) in the Chinese patients were higher than those in the non-Chinese patients.The proportions of the Chinese patients treated with tripterygium glycosides (9.4% <i>vs.</i> 0,<i>P</i>=0.008),dupilumab (18.8% <i>vs.</i> 0.8%,<i>P</i><0.001),and topical corticosteroids (87.5% <i>vs.</i> 53.5%,<i>P</i><0.001) were higher than those of non-Chinese patients.

Methods A total of 121 BOT patients undergoing fertility-sparing surgery between January 2010 and October 2022 were retrospectively analyzed.The univariate analysis,multivariate analysis,and survival curves were employed to evaluate the clinicopathological and surgical variables and fertility. Results The 121 BOT patients included in this study showed the 5-year recurrence-free survival (RFS) rate of 65.8% and the recurrence rate of 30.5%.A total of 53 patients attempted to conceive and 40 (33.06%) of the patients achieved successful pregnancy.Different methods of fertility-sparing surgery did not affect the tumor recurrence rate,RFS,or pregnancy rate.The multivariate analysis indicated that the International Federation of Gynecology and Obstetrics (FIGO) stage ≥Ⅱ was an independent risk factor affecting both postoperative recurrence and RFS (<i>P</i>=0.011,<i>OR</i>=6.504,95%<i>CI</i>=1.534-27.58;<i>P</i>=0.033,<i>HR</i>=2.589,95%<i>CI</i>=1.082-6.194) in BOT patients.Tissue type (mucinous) was negatively correlated with the risk of recurrence after fertility-sparing surgery (<i>P</i>=0.011,<i>OR</i>=0.270,95%<i>CI</i>=0.099-0.739).The two unilateral surgical methods showed differences in the amount of intraoperative bleeding (<i>P</i>=0.010),postoperative hospital stay (<i>P</i>=0.001),duration of antibiotic use (<i>P</i>=0.002),and tumor rupture rate (<i>P</i>=0.030),which were not significantly different between the two bilateral surgical methods.
