Drugs which have different effects were used, e.g. Fluorouracil, Cisplatin, APR-246 (which reactivates mutant p53), kevetrin (which activates wild p53). The function of ESCC is thought to differ depending on TP53 mutation status, and it is suggested that prognosis may be improved by the selection of drugs according to TP53 mutation status. We integrate and analyze clinical information and TP53 DNA, RNA status from ESCC specimens, and report this theme along with the relevant literature.
