Chemosensitivity of xenograft lines to cisplatin and paclitaxel. Xenograft lines received a combined dose of cisplatin and paclitaxel when the tumors averaged 250 mm3 to 300 mm3 (black arrow indicates time of treatment). (a) Line 1 was treated in passage 11 and was chemo-sensitive while (b) line 8 was treated in passage 5 and proved to be chemo-resistant.
