The tumour was characterised as stage IV, poorly differentiated. Immunocytochemical staining of the cells was reported to show strong staining for cytokeratin (CK), weak staining for carcinoembryonic antigen (CEA) and strong staining for human milk fat globulin (HMFG-2). Production of vascular endothelial growth factor (VEGF) has been detected by ELISA. The patient had received sequential treatment with cisplatin and cyclophosphamide, cisplatin and etoposide and subsequently tamoxifen.
