AbstractBiopsies from 117 patients with cervical carcinoma were studied using a clonogenic assay to assess in vitro growth. Successful colony growth was achieved in 84 tumours (72%) with a mean colony-forming efficiency (CFE), based on total viable nucleated cell counts, of 0.18 +/- 0.49% (+/- 1 standard deviation). There was a wide range of values, from 0.003-4.28%, with a coefficient of variation of 272%. The relationship between clinical features of cervical carcinoma and in vitro colony formation was investigated. No significant association was demonstrated between in vitro growth and either clinical stage (r = 0.02), tumour differentiation (r = -0.08) or patient age (r = -0.12). There was no significant difference in tumour grade between the group of tumours which failed to grow in culture and those which grew well (p = 0.70). In addition, there was no correlation between CFE and the degree of macrophage (r = 0.001), lymphocyte (r = 0.12), or granulocyte (r = 0.08) infiltration. There was no significant difference between CFEs of tumours from patients who had died and from those who were alive and well after a minimum of 2 years' follow-up after radiotherapy (p = 0.51). Ability to form colonies in agar was not associated with a worse prognosis (p = 0.49). Although CFE is an independent biological parameter, our results suggest that, for cervical carcinoma, it is not useful as a univariate prognostic factor.
