Nonsteroidal anti-inflammatory drugs (NSAIDs) exhibit cancer preventive effects and have been shown to induce regression of adenomas in FAP patients. In order to elucidate the probable underlying mechanism, the effect of NSAIDs on mismatch repair related microsatellite instability was investigated. Six colorectal cancer cell lines all but one deficient for human mismatch repair (MMR) genes were examined for microsatellite instability (MSI) prior and after treatment with Aspirin or Sulindac. For rapid in vitro analysis of MSI a microcloning assay was developed by combining Laser microdissection and random (PEP-) PCR prior to specific MSI-PCR. Effects of NSAIDs on cell cycle and apoptosis were systematically investigated by using flow cytometry and cell-sorting. MSI frequency in cells deficient of MMR genes (hMSH2, hMLH1, hMSH6) was markedly reduced after long-term (> 10 weeks) NSAID treatment. This effect was reversible, time- and concentration dependent. However, in the hPMS2 deficient endometrial cancer cell line (HEC-1-A) the MSI phenotype kept unchanged. According to cell sorting, non-apoptotic cells were stable and apoptotic cells were unstable. These results suggest that aspirin/sulindac induces a genetic selection for microsatellite stability in a subset of MMR-deficient cells and may thus provide an effective prophylactic therapy for HNPCC related colorectal carcinomas.

Prognosis of patients with stage IVB endometrial adenocarcinoma is quite poor. Combination therapy of radiation with surgery or chemotherapy is a common therapy for advanced endometrial cancers. However, radiation therapy is effective only for localized cancer, and the chemotherapeutic effect on stage IVB endometrial cancers is very low. We present a patient with stage IVB endometrial adenocarcinoma, whose tumor was not resected completely at the first surgery. She showed a remarkable response to a PEP (pirarubicin, etoposide, cisplatin) regimen and has survived without disease over 8 years. This case suggests that reduction surgery following PEP therapy is a new therapeutic modality for stage IVB endometrial carcinoma.
