The cells obtained from 138 tumor samples taken from 135 patients with colorectal malignancies were cultured in vitro in a soft agar colony formation assay similar to that of Salmon and colleagues [l]. Significant colony formation occurred for 63 (51 %) of evaluable tumor cultures, 53 of which were

β¦ Synopsis
The cells obtained from four established human colon carcinoma cell lines were cultured in soft agar in the presence of eight chemotherapeutic agents that have been used clinically in patients with metastatic colorectal carcinoma. 5-Fluorouracil, mitomycin C , adriamycin, and cis-platinum were highly cytotoxic in vitro at the concentrations employed. These findings were in marked contrast to in vitro chemotherapy sensitivity patterns previously reported by us for a large series of primary human colorectal carcinomas cultured in soft agar. The possible reasons behind these differences are discussed.
