Abstract
Cisplatin is a valuable adjuvant to radiotherapy for the treatment of cervical cancer. Because the advantage of combining cisplatin with radiotherapy is likely to be attributable to additive cell killing by these 2 agents, such protocols should primarily benefit patients who have inherently cisplatin-sensitive tumors. Development of a molecular assay to rapidly evaluate the cisplatin responsiveness of cervical tumors would thus be extremely valuable. We investigated whether high pre-treatment mRNA levels of the ERCC1 nucleotide excision repair gene are predictive of cisplatin resistance in early-passage human cervical cancer cells, as they are in several other tumor types. Expression of the ERCC1 gene at the mRNA and protein levels was established by Northern and Western blotting, respectively, in a panel of single-cell-derived cervical carcinoma cell lines that exhibited a wide range of inherent sensitivity to cisplatin. There was a significant (p </= 0.011) correlation between ERCC1 mRNA levels and cisplatin resistance in these cell lines. However, there was no obvious relationship between ERCC1 protein levels and cisplatin resistance. Thus, the association between high ERCC1 mRNA levels and cisplatin resistance might be an epiphenomenon. Nonetheless, pre-treatment ERCC1 mRNA levels may be a useful molecular marker for identifying cervical tumors likely to be refractory to cisplatin, and further investigation in clinical biopsy material is warranted.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
