[Relationship between the effectiveness of CDDP therapy and the nuclear DNA content in advanced-recurrent gastric cancer cases].
A microspectrophotometric analysis of the DNA content has been performed on 9 advanced recurrent gastric cancer patients with measurable lesions, who has either been treated by CDDP alone or with other chemotherapeutics during a three-year period since, 1984. Histograms of the DNA content were classified into four ploidy patterns. All of the 4 responder cases (CR, PR, MR) showed type, IV, although only one of 5 non-responder cases revealed the same typing. In one of the two CR cases the DNA ploidy pattern, which was examined before and after the therapy, changed from type IV to type II. Thus it appears that an analysis of the DNA content may be useful in evaluating the effectiveness of different chemotherapies.
