摘要目的:探究经尿道钬激光整块切除术与等离子电切术治疗高危非肌层浸润性膀胱癌(NMIBC)的临床效果。方法:纳入2018年3月至2020年3月我院96例高危NMIBC患者,随机分为电切组(48例)和钬激光组(48例),分别行经尿道膀胱肿瘤等离子电切术、经尿道膀胱肿瘤钬激光整块切除术治疗。比较两组手术情况、术后康复情况、血清炎性因子[高迁移率族蛋白1(HMGB1)、白细胞介素-6(IL-6)、肿瘤坏死因子α(TNF-α)]、微小RNA-200b(miR-200b)、miR-119a水平、并发症发生率。术后随访2年,比较两组复发、转移及生存状况。结果:钬激光组相比电切组出血量少[(20.86±5.08)ml vs. (23.71±5.42)ml],膀胱持续冲洗时间[(13.15±3.62)h vs. (17.08±5.13)h]、导尿管留置时间[(2.38±1.16)d vs. (4.17±1.42)d]和住院时间短[(5.03±1.37)d vs. (5.92±1.45)d],并发症总发生率低[4.17%(2/48)16.67% vs. (8/48)],差异均具有统计学意义(P<0.05)。钬激光组相比电切组术后3 d血清HMGB1、IL-6、TNF-α水平低,两组患者术后3个月相比术前血清miR-200b水平高,miR-119a水平低,差异均具有统计学意义(P<0.05)。术后随访2年,钬激光组脱落2例,电切组脱落4例。钬激光组复发率、转移率较电切组低,差异具有统计学意义(P<0.05)。结论:与经尿道膀胱肿瘤等离子电切术比较,采用经尿道膀胱肿瘤钬激光整块切除术治疗高危NMIBC疗效可靠,且能明显减轻手术创伤,降低术后并发症发生率,促进术后康复,减少肿瘤复发和转移。
Abstract:Objective: To investigate the clinical effect of transurethral holmium laser en bloc resection and plasma electrosurgery in the treatment of high-risk non-muscle invasive bladder cancer (NMIBC). Methods: 96 patients with high-risk NMIBC in our hospital from March 2018 to March 2020 were selected and randomly divided into electrosurgery group (48 cases) and holmium laser group (48 cases). The holmium laser group was treated with en bloc holmium laser resection of the bladder tumor through the urethra. The operation conditions (operation time, blood loss), postoperative rehabilitation (continuous bladder irrigation time, urinary catheter indwelling time, hospital stay), tthe incidence of complications and serum inflammatory factors [High mobility group protein 11 (HMGB1), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α)], microRNA-200b (miR-200b), miR-119a levels, postoperative follow-up 2 Years, the recurrence, metastasis and survival status of the two groups were statistically compared. Results: Compared with electrosurgery group, holium laser group had lower hemorrhagic volume [(20.86±5.08)ml vs. (23.71±5.42)ml], duration of persistent bladder irrigation [(13.15±3.62)h vs. (17.08±5.13)h], duration of catheter indwelling [(2.38±1.16)d vs. (4.17±1.42)d], and short hospital stay [(5.03±1.37)d vs. (5.92±1.45)d], and lower overall complication rate [4.17%(2/48)16.67%vs(8/48)], with statistical significance (P<0.05).Serum levels of HMGB1, IL-6, and TNF-α were lower in the holimu laser group than in electrosurgery group at 3 days postoperatively, and the differences in serum levels of miR-200b and miR-119a were significant (P<0.05).After postoperative follow-up of 2 years, 2 patients in the holium laser group and 4 in the electrosurgery group had radiographic drops.The recurrence and metastasis rates were lower in the holium laser group than in the electrosurgery group, and the difference was statistically significant (P<0.05). Conclusion: Compared with transurethral plasma electroresection of bladder tumor, transurethral en bloc resection of bladder tumor with holmium laser in the treatment of high-risk NMIBC has a reliable effect, and can significantly reduce the surgical trauma, reduce the incidence of postoperative complications, and promote postoperative recovery. Reduce tumor recurrence and metastasis.
