Posttreatment imaging demonstrated a partial response (thoracic CT showed a single subpleural nodule, while abdominal CT demonstrated a reduction in the number and size of hepatic lesions compared to the previous study, with the largest lesion reported in Segment II, measuring 14 × 23 mm) and negative tumor markers (AFP, 7.12; hCG, 0.12; and LDH, 211). The gene discussed is AFP; the disease is neoplasm.
