title: [In vitro chemosensitivity test for hepatocellular carcinoma using collagen-gel droplet embedded cultures].
abstract: This study evaluated an in vitro assay for chemosensitivity test using a collagen-gel droplet-embedded culture drug sensitivity test (CD-DST) for hepatocellular carcinoma (HCC). In 25 patients with HCC, in vitro chemosensitivity to 5-fluorouracil (5-FU), epirubicin (EPI), and cisplatin (CDDP) was examined by CD-DST, and 5-FU, EPI, and paclitaxel (PTX) were examined in 38 patients with breast cancer. Successful rates of chemosensitive evaluation by CD-DST were 64% for HCC and 79% for breast cancers. Although chemosensitivities of breast cancer were 5-FU 23.1%, EPI 83.3%, and PTX 67.7%, only one HCC sample was sensitive to EPI. Growth rates of HCC for 7 days of culture were significantly lower than those of breast cancers (1.04 vs 3.61). The culture methods for HCC in CD-DST should be improved to estimate accurate results.
