A phase I study of cisplatin i.p. and carboplatin i.v. with G-CSF in patients with ovarian cancer.

We conducted a dose-escalation study with a fixed dose of intraperitoneal cisplatin and G-CSF support of carboplatin using the Calvert formula in epithelial ovarian cancer. Twenty-five patients were entered in this study. On day 1, carboplatin was administered intravenously at target AUCs of 4, 5, 6, and 7. On day 2, cisplatin was given i.p. in 70 mg/m2. G-CSF, 50 microgram/m2, was administered subcutaneously from day 7 to 16. Cycles were scheduled to be delivered every four weeks. A total of 85 cycles were administered. The maximum tolerated dose was AUC 7 mg/ml x min of carboplatin. The overall response rate was 80% (12/15). The combination in this regimen is feasible, and a phase II study of this regimen is warranted.

Prognostic results of cisplatin IP and carboplatin IV with G-CSF in patients with ovarian cancer.

We performed a dose-escalation study of carboplatin combined with a fixed dose of intraperitoneal cisplatin and G-CSF in patients with epithelial ovarian cancer, and analyzed the progression-free and overall survival. Six of the patients who entered the study with stage IC and II disease are still alive with no evidence of disease. The five-year survival rate was 61% for the 18 patients with stage III and IV disease; progression-free survival over 5 years was 32%. Our results show this to be an effective treatment regimen for epithelial ovarian cancer. Prognosis is good with this combined carboplatin/cisplatin/G-CSF therapy, especially for those patients with microscopic or no residual disease.

Evaluation of a new method for identification of bacteria based on sequence homology of 16S rRNA gene.

A new identification method for bacteria based on partial sequences of divergent regions of the 16S rRNA gene was evaluated. The method involves PCR-based amplification of 16S rRNA gene fragments, followed by sequencing and comparison of sequences of about 300 nucleotides with those in the database of NCBI (National Center for Biotechnology Information) via the Internet. Most of the bacteria tested could be identified at the species level even if some unread nucleotides were present in the sequence. Although this method still requires improvement, it has the potential to be a highly reliable and practical identification method for bacteria.
