Primary squamous cell carcinoma (SqCC) often occurs in the trachea and bronchi. Recently, intraluminal bronchoscopic treatment (IBT) has emerged as an option for curative treatment, not just surgery, in patients with central early-stage SqCC (CES-SqCC). However, patients that can be cured by IBT are limited. We report a rare case of CES-SqCC that was surgically confirmed to be cured by IBT alone. A 72-year-old woman had a nodular bronchial tumor at the bifurcation of right upper and intermediate bronchi. For histological diagnosis, the tumor was resected and incinerated using high-frequency snare (HFS). Obtained specimens were diagnosed as SqCC; wedge resection of the bifurcation was performed to remove the residual lesion. However, no malignant findings were found in the excised specimens. Some patients with CES-SqCC may be cured by aggressive diagnostic bronchoscopy. The risk of postoperative complications cannot be ignored because the surgery requires bronchoplasty in patients with CES-SqCC. For patients with CES-SqCC, surgical resection may be avoided by detailed assessment of residual lesion with radial probe endobronchial ultrasonography (RP-EBUS).

腔内支气管镜治疗治愈结节型中央鳞状细胞肺癌1例报告

原发性鳞状细胞癌 (SqCC) 常发生于气管和支气管。最近,腔内支气管镜治疗 (IBT) 已成为中央早期 SqCC (CES-SqCC) 患者的治愈性治疗选择,而不仅仅是手术。然而,可以通过 IBT 治愈的患者是有限的。我们报告了一例经手术证实仅通过 IBT 治愈的 CES-SqCC 罕见病例。一名 72 岁女性在右上支气管和中间支气管分叉处有一个结节性支气管肿瘤。对于组织学诊断,使用高频圈套器(HFS)切除和焚烧肿瘤。获得的标本被诊断为SqCC;对分叉处进行楔形切除以去除残留病灶。然而,在切除的标本中没有发现恶性发现。一些 CES-SqCC 患者可以通过积极的诊断性支气管镜检查治愈。术后并发症的风险不容忽视,因为手术需要对 CES-SqCC 患者进行支气管成形术。对于 CES-SqCC 患者,可以通过使用径向探针支气管内超声 (RP-EBUS) 详细评估残留病变来避免手术切除。
