A subset of non-small cell lung carcinoma (NSCC) harbor active mutations of epidermal growth factor receptor (EGFR). In these, EGFR tyrosine kinase inhibitors (EGFR-TKIs) are recommended as the first-line treatment. Though drug resistance is inevitable, histological transformation to small cell lung carcinoma (SCLC) is a rare mechanism for acquired resistance. Here we report one such rare case of histological transformation of pulmonary adenocarcinoma to small cell lung carcinoma in 46 year old male treated with Gefitinib.
一部分非小细胞肺癌(NSCC)存在表皮生长因子受体(EGFR)的活性突变。对于这些患者,推荐将表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKIs)作为一线治疗药物。尽管耐药不可避免,但组织学转化为小细胞肺癌(SCLC)是获得性耐药的一种罕见机制。在此,我们报告一例46岁男性肺腺癌组织学转化为小细胞肺癌的罕见病例,该患者接受了吉非替尼治疗。
