case_images: The right middle lobe bronchus exhibited a mass that completely obstructed the lumen, whereas all levels of the left bronchus remained patent with smooth mucosa (Fig. 1A). P40 (-) (Fig. 1B). Pathology confirmed the diagnosis of SCLC, necessitating the consideration of concurrent large-cell neuroendocrine carcinoma. The first-line treatment consisted of 6 cycles of chemotherapy based on the EP regimen (etoposide + carboplatin), with treatment efficacy assessed as a partial response (PR) (Fig. 1C).

case_images: After treatment, the patient's abdominal pain significantly improved, amylase levels normalized (Table 1 and Fig. 3A), and NSE levels significantly decreased (Fig. 3B), indicating an effective treatment. A follow-up abdominal CT scan, however, revealed an increase in the size of the pancreatic lesions compared to the previous imaging (Fig. 3C).
