OBJECTIVE: The aim of this study is to evaluate the efficacy of carboplatin-paclitaxel (TC) as an initial treatment in patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IVb cervical cancer. METHODS: We retrospectively reviewed seven patients with stage IVb cervical cancer who have been primarily treated with TC. The activity and the toxicity were evaluated. Response rate was the main endpoint. RESULTS: Overall, the treatment of TC was well tolerated. The overall response rate was 71.4% (2 complete response, 3 partial response). Although grade 3-4 hematologic toxicities were observed in 3 out of 7 patients (42.8%), no patients experienced grade 3-4 non-hematologic toxicities. When we combined our present results with the previous reports, the overall response rate of TC is 63.6%. CONCLUSION: TC is active and well tolerated in patients FIGO stage IVb cervical cancer. This combination may be considered as an initial treatment regimen in this patient population.

Primary peritoneal serous papillary carcinoma (PPSPC) is a rare tumor that originates from a single or multicentric foci of peritoneum. Histologically the disease resembles primary serous papillary carcinoma of the ovary, but either involves the ovarian surface microscopically only or spares the ovaries entirely. Currently PPSPC is evaluated, staged and treated in the same way as epithelial ovarian cancer. We experienced one case of primary peritoneal serous papillary carcinoma which achieved a complete remission with carboplatin and paclitaxel, and report this with brief review of the literatures.

Progress in chemotherapeutic strategy has significantly decreased side effects of the drugs used and greatly added to survival rates for ovarian cancer. On the other hand, the occurrence of myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) has been reported after long-term chemotherapy. We encountered a case of therapy-related MDS that developed as a consequence of chemotherapy. A 59-year-old woman (gravida 2, para 2) stage IIIc ovarian cancer received three courses of paclitaxel and carboplatin therapy (TC) prior to primary surgery, and 16 courses of weekly TC as adjuvant chemotherapy. She exhibited pacritaxel-associated hypersensitivity reactions in the last course, so that chemotherapy was discontinued. Following three mouths of remission, a sudden rise in her tumor markers and an increase in the size of her pelvic lymphonode were discovered on PET-CT. She recieved multiple courses of chemotherary of docetaxel/carboplatin, weekly docetaxel, docetaxel/briplatin and Gemcitabin/Irinotecan between four months. In 30 months after diagnosis, complete blood count showed hemoglobin 7.7 g/dl; white cell count 4,310/μl; and platelet 7.9×104/μl. A bone marrow examination revealed MDS. She then decided against further chemotherapy, opting instead for palliative care. Fortunately, up to the present, she has not developed AML.

To preliminarily determine the appropriate dosage of carboplatin (CBP) at AUC of 5 mg.Ml(-1).min(-1) in the combination chemotherapy for Chinese senile patients with non-small cell lung cancer (NSCLC). Thirty-five Chinese senile patients with NSCLC in advanced stage (III/IV) were given 96 cycles of combination chemotherapy. Chemotherapy schedules included Taxol+CBP, Gemzar+CBP and NVB+CBP. The dose of CBP was at 5 mg.mL(-1).min(-1) of area under the concentration-time curve (AUC). Side effects and quality of life were observed before and after the chemotherapy. Myelosuppression was severe and commonly observed. Grade 3/4 of granulocytopenia was found in 47.9% (46/96) of the patients and grade 3/4 of thrombocytopenia was noted in 28.1% (27/96) of the subjects. However, other side effects were slight. The mean score of quality of life (QOL), according to the criteria of QOL for Chinese cancer patients had reduced 6.8. At 5 mg.mL(-1).min(-1) by AUC, the hematological toxicity of CBP was severe and it had some negative effects on the QOL. The administration of CBP at 5 mg.mL(-1).min(-1) by AUC may be too high for Chinese senile patients with non-small cell lung cancer.

BACKGROUND: To compare the efficacies and side effects of etoposide, cisplatin/cyclophosphamide, adriamycin, vincristine(VPP/CAV) with that those of carboplatin etoposide(CE) in extensive stage small cell lung cancer patients. METHOD: Patients with extensive stage small cell lung cancer who has measurable disease were eligible. VPP/CAV group(n=22) was treated with cisplatin(60mg/m2 iv. D1) etoposide(100mg/m2 iv. D1-3),after and 3 weeks later cyclophosphamide(1000mg/m2 iv. D1), adriamycin(40mg/m2 iv. D1), and vincristine(1.4mg/m2 iv. D1), were administered alternatively. CE group (n=22) was treated with carboplatin (325mg/m2 iv. D1) and etoposide (100mg/m2 iv. D1-3)(;) repeated treatment was performed every 3 weeks. RESULT: Forty four patients were eligible for the study. Overall The overall response rate was 61.4% (complete remission rate 0%, partial response rate 61.4%, stable disease rate 25%, progressive disease rate 13.6%), and median survival was 10.8 months. In VPP/CAV group, response rate was 54.5%(complete remission rate 0%, partial response rate 54.4%, stable disease rate 27.3%, progressive disease rate 18.2%), and, in carboplatin/etoposide group, the response rate was 68.2%(complete remission rate 0%, partial response rate 68.2%, stable disease rate 22.7%, progressive disease rate 9.1%). The median survival time was 9.5 months in the VPP/CAV group and 11 months in CE group. The toxicity of both group was moderate, and anemia was more frequent in the CE group. CONCLUSION: VPP/CAV regimen and CE regimen produced similar response rate and survival time rates and survival times in extensive stage small cell lung cancer patients. We may suggest that CE regimen are effective may be effective as part of the initial therapy of for extensive stage small cell lung cancer.

In solid tumor, there is a hypoxic region where oxygen supply is insufficient. In this study, we found that one of the quinolone antibiotics, levofloxacin, made a human ovarian cancer cells, SK-OV-3, resistant to hypoxia, even in the presence of a platinum-based anti-cancer therapeutic, carboplatin; when the cells (2 X 10(5) cells/12 well multi culture dish) were grown in no glucose medium (0 g/l) under hypoxia (1% O2), all the cells became dead after 24 hours of culture in the absence of levofloxacin and carboplatin, whereas the cells still survived, at least, until 36 hours of culture in the presence of levofloxacin (10-100 microgram/ml) alone or in combination with carboplatin. The results might have some implications in treating solid tumor; if cancer patients should be treated for infection with antibiotics, quinolone antibiotics can aggravate tumor by making cancer cells more resistant to hypoxia. This is also true even when a patient is treated with carboplatin. Therefore, the results strongly suggest that we should be careful in choosing antibiotics when they are used for cancer patients. In this regard, our work could be a new guideline in choosing antibiotics when antibiotics are applied for treating cancer patients.

Multicellul ar tumor spheroids of HeLa cells have been grown in a static culture system. Samples of spheroids were exposed for 2 h to graded concentration of sis-platinum and its analogue, carboplatin, and then response assayed by survival of clonogenic cells. The purpose of present experiment is to clarify the effectiveness of these platinum compounds and to evaluate intrinsic radiosensitivity of cells using spheroids of HeLa cells as an experimental in vitro model. Variations of the drug sensitivity of monolayers as well as spheroids were also evaluated in cell-survival curves. In cia-platinum concentration-survival cutie, there was a large shoulder extending as far as Cq=3.4 mM, after which there was exponential decrease in survival curve having a Co Value of 1.2 mu in spheroids. While the Co for the spheroids was essentially no significant change, but Cq value was larger than that of monolayers. This suggest that the effect of cis-platinum is greater in the monolayer with actively proliferaing cells than hypoxic one. In the carboplatin concentration-survival curves, the Co value of spheroids was 15.0 mM and the ratio with the Co from monolayer cell (32.5 mM) was 0.46, thus indicating that the spheroids had a greater sensitivity to carboplatin than monolayers. Therefore, the effect of carboplatin is mainly on the deeper layers of spheroids acting as hypoxic cell sensitizer. The enhanced effect was obtained for monolayer cells using combined X-ray and carboplatin treatment 2 hours before irradiation. The result shown in isobologram analysis for the level of surviving fraction at 0.01 indicated that the effect of two agents was truely supra-additive. From this experimental data, carboplatin has excited much recept interest as one of the most promising, since it is almost without nephrotoxicity and causes less gastrointestinal toxicity than cia-platinum. Interaction between carboplatin and radiation might play an important role for more effective local tumor control.

OBJECTIVE: This phase I study aimed to determine the maximum tolerated dose (MTD) of Genexol-PM, when combined with carboplatin, as a first-line treatment in patients with advanced ovarian cancer. METHODS: This open-label, multicenter, phase I, dose-escalation study included 18 patients (median age: 59.0 years, range: 40–75 years) diagnosed with advanced epithelial ovarian cancer. All patients had measurable residual disease after debulking surgery. Patients were assigned to groups (n=6 each group) that received different doses of Genexol-PM (220, 260, and 300 mg/m², once every 3 weeks) and 5 area under the curve (AUC) carboplatin. Safety and efficacy were analyzed for each dose group. RESULTS: In this intention-to-treat population, 3 out of 18 patients dropped out of the study: 1 due to dose-limiting toxicity (DLT), 1 due to hypersensitivity, and 1 was lost during follow-up. DLTs were not reported at 220 mg/m² or 260 mg/m², but at 300 mg/m², 1 patient experienced DLT (grade 3 general pain). The MTD of Genexol-PM was not determined, but a dose of 300 mg/m² or less could be recommended for the phase II study. Most patients (73.9%) with adverse events recovered without sequelae, and no death occurred that was related to the disease or treatment. The best overall response rate was 94.1%. CONCLUSION: Genexol-PM combined with carboplatin was well tolerated as a first-line treatment, and good responses were observed in patients with advanced ovarian cancer. Based on these results, we recommended a dose of 300 mg/m² or less for a phase II study.
