摘要

一名 69 岁的前吸烟日本男子因左纵隔淋巴结和左肺上叶肿瘤就诊。从肿大的左纵隔淋巴结和左上叶肿瘤中取出的支气管镜活检标本显示为小细胞肺癌(SCLC)。他接受了卡铂、依托泊苷和阿特珠单抗四疗程的一线化疗,随后接受了阿特珠单抗维持治疗。然而,他的左上肺叶肿瘤只是增大了,左上肺叶切除术后发现合并了SCLC(腺癌和软骨肉瘤样特征)。左上肺叶切除术后四个月,观察到软骨肉瘤样特征的肝转移(与左上肺叶肿瘤的病理结果相似)。包括肉瘤成分在内的合并 SCLC 非常罕见,且对化疗反应差。该患者的合并 SCLC 转移瘤只有一种组织学成分,给诊断和治疗带来了困难。如果对SCLC的治疗反应不佳,有必要考虑合并SCLC,并积极重新检查组织学诊断。

A combined small cell lung carcinoma patient with only small cell carcinoma components in mediastinal lymph node metastasis and chondrosarcoma-like components in liver metastasis.

A 69-year-old ex-smoker Japanese man presented with a left mediastinal lymph node and left upper lobe tumour. Bronchoscopic biopsy specimens from the enlarged left mediastinal lymph node and left upper lobe tumour revealed small cell lung carcinoma (SCLC). He was treated with first-line chemotherapy with carboplatin, etoposide, and atezolizumab for four courses and subsequent atezolizumab maintenance therapy. However, his left upper lobe lung tumour only increased in size, and left upper lobectomy revealed combined SCLC (adenocarcinoma and chondrosarcoma-like features). Four months after lobectomy, liver metastasis of chondrosarcoma-like features (similar to pathological findings of the left upper lobe tumour) were observed. Combined SCLC, including sarcomatous components, is rare and poorly responds to chemotherapy. The metastases of combined SCLC in this patient were of only one type of histological component, making diagnosis and treatment difficult. If treatment for SCLC responds inadequately, considering combined SCLC and actively re-examining histological diagnosis is necessary.
