Iida Y, Okamoto A, Hollis RL, Gourley C, Herrington CS. Clear cell carcinoma of the ovary: a clinical and molecular perspective. Int J Gynecol Cancer 2020; 31:605-616. [PMID: 32948640 DOI: 10.1136/ijgc-2020-001656] [Citation(s) in RCA: 69] [Impact Index Per Article: 17.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 08/13/2020] [Accepted: 08/17/2020] [Indexed: 12/14/2022] Open
Abstract
Clear cell carcinoma of the ovary has distinct biology and clinical behavior. There are significant geographical and racial differences in the incidence of clear cell carcinoma compared with other epithelial ovarian tumors. Patients with clear cell carcinoma are younger, tend to present at an early stage, and their tumors are commonly associated with endometriosis, which is widely accepted as a direct precursor of clear cell carcinoma and has been identified pathologically in approximately 50% of clear cell carcinoma cases. The most frequent and important specific gene alterations in clear cell carcinoma are mutations of AT-rich interaction domain 1A (ARID1A) (~50% of cases) and phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) (~50% cases). More broadly, subgroups of clear cell carcinoma have been identified based on C-APOBEC (apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like) and C-AGE (age-related) mutational signatures. Gene expression profiling shows upregulation of hepatocyte nuclear factor 1-beta (HNF1β) and oxidative stress-related genes, and has identified epithelial-like and mesenchymal-like tumor subgroups. Although the benefit of platinum-based chemotherapy is not clearly defined it remains the mainstay of first-line therapy. Patients with early-stage disease have a favorable clinical outcome but the prognosis of patients with advanced-stage or recurrent disease is poor. Alternative treatment strategies are required to improve patient outcome and the development of targeted therapies based on molecular characteristics is a promising approach. Improved specificity of the histological definition of this tumor type is helping these efforts but, due to the rarity of clear cell carcinoma, international collaboration will be essential to design appropriately powered, large-scale clinical trials.

Targeting an autocrine IL-6-SPINK1 signaling axis to suppress metastatic spread in ovarian clear cell carcinoma. Oncogene 2020; 39:6606-6618. [PMID: 32929152 PMCID: PMC7572712 DOI: 10.1038/s41388-020-01451-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2019] [Revised: 08/19/2020] [Accepted: 09/02/2020] [Indexed: 01/09/2023]
Abstract
A major clinical challenge of ovarian cancer is the development of
malignant ascites accompanied by widespread peritoneal metastasis. In ovarian
clear cell carcinoma (OCCC), a challenging subtype of ovarian cancer, this
problem is compounded by near-universal primary chemoresistance; patients with
advanced stage OCCC thus lack effective therapies and face extremely poor
survival rates. Here we show that tumor cell expressed serine protease inhibitor
Kazal type 1 (SPINK1) is a key driver of OCCC progression and metastasis. Using
cell culture models of human OCCC, we find that shRNA silencing of SPINK1
sensitizes tumor cells to anoikis and inhibits proliferation. Knockdown of
SPINK1 in OCCC cells also profoundly suppresses peritoneal metastasis in mouse
implantation models of human OCCC. We next identify a novel autocrine signaling
axis in OCCC cells whereby tumor cell-produced interleukin-6 (IL-6) regulates
SPINK1 expression to stimulate a common protumorigenic gene expression pattern
leading to anoikis resistance and proliferation of OCCC cells. We further
demonstrate that this signaling pathway can be successfully interrupted with the
IL-6Rα inhibitor tocilizumab, sensitizing cells to anoikis in
vitro and reducing metastasis in vivo. These
results suggest that clinical trials of IL-6 pathway inhibitors in OCCC may be
warranted, and that SPINK1 might offer a candidate predictive biomarker in this
population.

Long-term recurrence-free survival of a patient with advanced pure primary ovarian squamous cell carcinoma treated with dose-dense paclitaxel combined with carboplatin. Obstet Gynecol Sci 2017; 60:587-592. [PMID: 29184868 PMCID: PMC5694734 DOI: 10.5468/ogs.2017.60.6.587] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Revised: 05/06/2017] [Accepted: 05/24/2017] [Indexed: 11/22/2022] Open
Abstract
We describe an extremely rare case of advanced pure primary ovarian squamous cell carcinoma (SCC), treated by adjuvant chemotherapy with dose-dense paclitaxel combined with carboplatin (dd-TC) plus the combination chemotherapy with irinotecan and cisplatin (CPT-P), with long-term recurrence-free survival. A 71-year-old woman complaining of lower abdominal pain was referred to our hospital and a 7-cm-diameter solid tumor was identified. She was diagnosed with a left ovarian tumor that was highly suspicious for malignancy based on ultrasonography, magnetic resonance imaging, and contrast-enhanced computed tomography. Bilateral salpingo-oophorectomy, low-anterior colon resection, and colostomy were performed. Intra- and post-operative histopathological diagnosis revealed International Federation of Gynecology and Obstetrics stage IIIc well-differentiated pure ovarian SCC. As adjuvant chemotherapy, 2 courses of dd-TC were administered, followed by 3 courses of CPT-P; the patient then underwent 4 additional courses of dd-TC. Both regimens were effective and there has been no recurrence or metastasis thus far in the 5 years since the operation.

Abstract
The incidence rate of triple or more synchronous primary neoplasms of the female genital system is exceedingly uncommon. To the best of our knowledge, only 13 such cases have been reported in the PubMed-indexed English literature. Herein, we report a single case of triple synchronous primary neoplasms of the cervix, endometrium, and left ovary with three distinct histological patterns that were not reported previously. Moreover, we briefly present a summary table of all the English PubMed-indexed cases of triple or more synchronous primary neoplasms of the female genital system (n = 13).

Abstract
In this research poly(l-lysine)-b-poly(l-leucine) (PLys-b-PLeu) polymersomes were developed. It was shown that the size of nanoparticles depended on pH of self-assembly process and varied from 180 to 650nm. The biodegradation of PLys-b-PLeu nanoparticles was evaluated using in vitro polypeptide hydrolysis in two model enzymatic systems, as well as in human blood plasma. The experiments on the visualization of cellular uptake of rhodamine 6g-loaded and fluorescein-labeled nanoparticles were carried out and the possibility of their penetration into the cells was approved. The cytotoxicity of polymersomes obtained was tested using three cell lines, namely, HEK, NIH-3T3 and A549. It was shown that tested nanoparticles did not demonstrate any cytotoxicity in the concentrations up to 2mg/mL. The encapsulation of specific to colorectal cancer anti-tumor drug irinotecan into developed nanocontainers was performed by means of pH gradient method. The dispersion of drug-loaded polymersomes in PBS was stable at 4°C for a long time (at least 1month) without considerable drug leakage. The kinetics of drug release was thoroughly studied using two model enzymatic systems, human blood serum and PBS solution. The approximation of irinotecan release profiles with different mathematical drug release models was carried out and allowed identification of the release mechanism, as well as the morphological peculiarities of developed particles. The dependence of encapsulation efficiency, as well as maximal loading capacity, on initial drug concentration was studied. The maximal drug loading was found as 320±55μg/mg of polymersomes. In vitro anti-tumoral activity of irinotecan-loaded polymersomes on a colon cancer cell line (Caco-2) was measured and compared to that for free drug.

Abstract
Non-platinum single agents are usually used for patients with platinum-resistant recurrent ovarian cancers (ROC). However, the efficacy of these drugs is limited. The aim of the present study was to evaluate the efficacy and adverse events (AE) of combination therapy with irinotecan and platinum (CPT-Pt) for ROC. A total of 28 platinum-resistant or refractory patients with ROC treated with CPT-Pt at the National Defense Medical College Hospital institution between 2002 and 2012 were identified. All patients received taxane and carboplatin (TC) as a first-line treatment and relapsed within 6 months after completion of TC, or progressed during TC therapy. The median age was 59 years (range, 16-78), and median number of CPT-Pt therapy cycles was 5.5 (range, 2-16). The overall response rate was 14%, with a complete response (CR) in 2 patients and partial response (PR) in 2 patients. Stable disease (SD) for >3 months was observed in 15 patients (54%), resulting in a clinical benefit rate (CBR = CR + PR + SD) of 68%. The median progression-free survival and overall survival were 8 and 15 months, respectively. Fifteen cases (68%) developed grade 3/4 hematological AE and 3 cases (11%) developed non-hematological grade 3/4 AE, which were resolved by conservative management or dose reduction. Platinum re-treatment with irinotecan for platinum refractory or resistant ROC may be a candidate in such clinical settings.

Abstract
PURPOSE We report a phase II clinical study of the combination of irinotecan (CPT-11) and pegylated liposomal doxorubicin (PLD) in platinum- and taxane-resistant recurrent ovarian cancer, based on the recommended doses determined in a phase I trial. METHODS PLD was administered intravenously at a dose of 30 mg/m2 on day 3. CPT-11 was administered intravenously at a dose of 80 mg/m2 on days 1 and 15, according to the recommendations of the phase I study. A single course of chemotherapy lasted 28 days, and patients underwent at least 2 courses until disease progression. The primary endpoint was antitumor efficacy, and the secondary endpoints were adverse events, progression-free survival (PFS), and overall survival (OS). RESULTS The response rate was 32.3% and the disease control rate was 64.5%. Grade 3 and 4 neutropenia, anemia, and a decrease in platelet count were observed in 17 (54.9%), 3 (9.7%), and 1 patient (3.2%), respectively. In terms of grade 3 or higher non-hematologic toxicities, grade 3 nausea occurred in 1 patient (3.2%), vomiting in 3 patients (9.7%), and grade 3 diarrhea and fatigue in 1 patient (3.2%). The median PFS and OS rates were 2 months and not reached, respectively. Of the 11 patients with a treatment-free interval (TFI) of ≥3 months, the response rate was 63.3%, and the median PFS was 7 months. CONCLUSIONS The treatment outcomes for the 31 patients enrolled in this study were unsatisfactory. However, sub-analysis suggested that patients with a TFI of ≥3 months had a good response rate and PFS. This suggests that CPT-11/PLD combination therapy may be a chemotherapy option for platinum-resistant recurrent ovarian cancer.

Abstract
Clear cell carcinoma (CCC) of the ovary is known to show poorer sensitivity to chemotherapeutic agents and to be associated with a worse prognosis than the more common serous adenocarcinoma or endometrioid adenocarcinoma. To improve the survival of patients with ovarian CCC, the deeper understanding of the mechanism of CCC carcinogenesis as well as the efforts to develop novel treatment strategies in the setting of both front-line treatment and salvage treatment for recurrent disease are needed. In this presentation, we first summarize the mechanism responsible for carcinogenesis. Then, we highlight the promising therapeutic targets in ovarian CCC and provide information on the novel agents which inhibit these molecular targets. Moreover, we discuss on the cytotoxic anti-cancer agents that can be best combined with targeted agents in the treatment of ovarian CCC.

Abstract
Objective The objective of this study was to evaluate the antitumor effects of lurbinectedin as a single agent or in combination with existing anticancer agents for clear cell carcinoma (CCC) of the ovary, which is regarded as an aggressive, chemoresistant, histological subtype. Methods Using human ovarian CCC cell lines, the antitumor effects of lurbinectedin, SN-38, doxorubicin, cisplatin, and paclitaxel as single agents were assessed using the MTS assay. Then, the antitumor effects of combination therapies involving lurbinectedin and 1 of the other 4 agents were evaluated using isobologram analysis to examine whether these combinations displayed synergistic effects. The antitumor activity of each treatment was also examined using cisplatin-resistant and paclitaxel-resistant CCC sublines. Finally, we determined the effects of mTORC1 inhibition on the antitumor activity of lurbinectedin-based chemotherapy. Results Lurbinectedin exhibited significant antitumor activity toward chemosensitive and chemoresistant CCC cells in vitro. An examination of mouse CCC cell xenografts revealed that lurbinectedin significantly inhibits tumor growth. Among the tested combinations, lurbinectedin plus SN-38 resulted in a significant synergistic effect. This combination also had strong synergistic effects on both the cisplatin-resistant and paclitaxel-resistant CCC cell lines. Everolimus significantly enhanced the antitumor activity of lurbinectedin-based chemotherapies. Conclusions Lurbinectedin, a new agent that targets active transcription, exhibits antitumor activity in CCC when used as a single agent and has synergistic antitumor effects when combined with irinotecan. Our results indicate that lurbinectedin is a promising agent for treating ovarian CCC, both as a first-line treatment and as a salvage treatment for recurrent lesions that develop after platinum-based or paclitaxel treatment.

Abstract
Epithelial ovarian carcinoma consists of not one, but several, entities. A number of subtypes exist, including high-grade and low-grade serous carcinomas, clear cell, endometrioid carcinoma and mucinous carcinoma. Historically, women with epithelial ovarian cancer have been treated similarly and "lumped" in the same cooperative group treatment trials, irrespective of their tumor subtype. Recently, however, differences in epidemiology, tumor biology, tumor marker expression and treatment responses have been elucidated among the histologic subtypes, with a clear distinction emerging between the Type I, lower grade tumors and Type 2, higher grade epithelial malignancies. A mounting body of research demonstrates that a "one-size-fits-all" treatment approach to epithelial ovarian tumors is no longer relevant, especially for the Type I subtypes. Indeed, with the exception of high-grade serous carcinoma, most other epithelial subtypes exhibit some degree of chemotherapy resistance, rendering treatment problematic, especially in the setting of advanced disease. This review summarizes the genetic, molecular, and clinical differences of the more rare, but clinically important, Type I epithelial ovarian tumors. Additionally, a critical appraisal of both historical and contemporary treatment approaches and the rationale for targeted therapies are emphasized.

Abstract
The development of nanotechnological devices and their clinical application in medicine has become increasingly important, especially in the context of targeted and personalized therapy. This is particularly important in cancer therapy, where antitumor drugs are highly cytotoxic and often exert their therapeutic effect at concentrations close to systemic toxicity. In the last years a growing number of studies has started to report the use of plasmonic nanoprobes in the field of theranostics, broadening the application of vibrational spectroscopies like Raman scattering and surface enhanced Raman scattering (SERS) in biomedicine. The present work aims to identify and characterize the vibrational profiles of a widely used anticancer drug, irinotecan (CPT-11). With a rational approach, SERS experiments have been performed on this analyte employing both Au and Ag colloids, starting from simple aqueous solutions up to albumin mixtures. A major step forward for drug detection in albumin solutions has been taken with the adoption of a simple deproteinization strategy, and a two-in-one-step separation and identification by coupling thin layer chromatography, TLC, with SERS (TLC-SERS). The latter has revealed to be a valid system for protein separation and simultaneous analyte detection, showing a potential to become an innovative, sensitive and low cost method for antineoplastic drug profiling in patients' body fluids.

Abstract
Purpose A phase I clinical study was conducted to determine the maximum tolerated dose (MTD) and the recommended dose (RD) of irinotecan hydrochloride (CPT-11) in CPT-11/pegylated liposomal doxorubicin (PLD) combination therapy, a novel treatment regimen for platinum- and taxane-resistant recurrent ovarian cancer. Methods Pegylated liposomal doxorubicin was administered intravenously on day 3 at a fixed dose of 30 mg/m2. CPT-11 was administered intravenously on days 1 and 15, at a dose of 50 mg/m2 on both days. One course of chemotherapy was 28 days, and patients were given a maximum of six courses, with the CPT-11 dose being increased in increments of 10 mg/m2 (level 1, 50 mg/m2; level 2, 60 mg/m2; level 3, 70 mg/m2; level 4, 80 mg/m2) to determine MTD and RD. Results During the period from April 2010 to March 2013, three patients were enrolled for each level. In the first course, no dose-limiting toxicity occurred in any of the patients. Grade 4 neutropenia was observed in two of three patients at level 4. At level 4, the antitumor effect was a partial response (PR) in two of the three patients and stable disease (SD) in one. At level 3, one of the three patients showed PR and two had SD. At level 4, the start of the next course was postponed in two of three patients. In addition, one patient at level 4 experienced hemotoxicity that met the criteria for dose reduction in the next course. The above results suggested that administration of CPT-11 at dose level 5 (90 mg/m2) would result in more patients with severe neutropenia and in more patients requiring postponement of the next course or a dose reduction. Based on the above, the RD of CPT-11 was determined to be 80 mg/m2. Conclusions The results suggest that CPT-11/PLD combination therapy for recurrent ovarian cancer is a useful treatment method with a high response rate and manageable adverse reactions. In the future phase II study, the safety and efficacy of this therapy will be assessed at 80 mg/m2 of CPT-11 and 30 mg/m2 of PLD.

Abstract
The solid phase FTIR and FT-Raman spectra of Irinotecan have been recorded in the regions 400-4000 and 50-4000 cm(-1), respectively. The spectra were interpreted in terms of fundamentals modes, combination and overtone bands. The structure of the molecule was optimized and the structural characteristics were determined by density functional theory (DFT) using B3LYP method with 6-31G(d) as basis set. The vibrational frequencies were calculated for Irinotecan by DFT method and were compared with the experimental frequencies, which yield good agreement between observed and calculated frequencies. The infrared spectrum was also simulated from the calculated intensities. Besides, molecular electrostatic potential (MEP), frontier molecular orbitals (FMO) analysis were investigated using theoretical calculations.

Abstract
This study retrospectively compared nedaplatin and irinotecan hydrochloride (NDP/CPT) combination therapy with cisplatin and irinotecan hydrochloride therapy (CDDP/CPT) for efficacy and adverse events in the treatment of clear cell adenocarcinoma of the ovary (CCC) and recurrent ovarian carcinoma. A total of 115 patients were included in the present study. NDP/CPT was administered intravenously every 4 weeks (NDP, 60 mg/m(2) on day 1; CPT, 50 mg/m(2) on days 1, 8 and 15). CDDP/CPT was also administered intravenously (CDDP, 60 mg/m(2) on day 1; CPT, 60 mg/m(2) on days 1, 8 and 15). Patients with primary CCC were treated with NDP/CPT in 29 cases and CDDP/CPT in 20 cases. Patients with recurrent ovarian carcinoma were treated with NDP/CPT and CDDP/CPT in 33 cases each. No significant difference was observed in the 5-year overall survival (OS)/progression-free survival (PFS) of patients with primary CCC, with the exception of those patients with stages Ia and Ic(b) who underwent NDP/CPT and CDDP/CPT treatments (OS: 58%, PFS: 40% and OS: 53% and PFS: 47%, respectively). No significant differences were found in the response rates to NDP/CPT and CDDP/CPT in patients with recurrent ovarian carcinoma (27 and 18%, respectively). Similarly, there were no significant differences in the 5-year OS and PFS of patients with recurrent ovarian carcinoma treated with NDP/CPT or CDDP/CPT (OS: 15%, PFS: 3% and OS: 18%, PFS: 6%, respectively). In terms of the hematological toxicity of grade 3 or above and non-hematological toxicity of grade 2 or above in patients treated with NDP/CPT and CDDP/CPT, respectively, neutropenia was 23 and 56%; anemia, 1, and 20%; thrombocytopenia, 0 and 5%; nausea, 20 and 52%; diarrhea, 14 and 25%; and fever, 2 and 11%. Accordingly, NDP/CPT indicated mild toxicity, and was therefore equally effective and less toxic than CDDP/CPT in the treatment of primary CCC and recurrent ovarian carcinoma.

Abstract
Several clinical trials to establish standard treatment modality for ovarian cancers included a high abundance of patients with serous histologic tumors, which were quite sensitive to platinum-based chemotherapy. On the other hand, ovarian tumor with rare histologic subtypes such as clear cell or mucinous tumors have been recognized to show chemo-resistant phenotype, leading to poorer prognosis. Especially, clear cell carcinoma of the ovary (CCC) is a distinctive tumor, deriving from endometriosis or clear cell adenofibroma, and response rate to platinum-based therapy is extremely low. It was implied that complete surgical staging enabled us to distinguish a high risk group of recurrence in CCC patients whose disease was confined to the ovary (pT1M0); however, complete surgical staging procedures could not lead to improved survival. Moreover, the status of peritoneal cytology was recognized as an independent prognostic factor in early-staged CCC patients, even after complete surgical staging. In advanced cases with CCC, the patients with no residual tumor had significantly better survival than those with the tumor less than 1 cm or those with tumor diameter more than 1 cm. Therefore, the importance of achieving no macroscopic residual disease at primary surgery is so important compared with other histologic subtypes. On the other hand, many studies have shown that conventional platinum-based chemotherapy regimens yielded a poorer prognosis in patients with CCC than in patients with serous subtypes. The response rate by paclitaxel plus carboplatin (TC) was slightly higher, ranging from 22% to 56%, which was not satisfactory enough. Another regimen for CCC tumors is now being explored: irinotecan plus cisplatin, and molecular targeting agents. In this review article, we discuss the surgical issues for early-staged and advanced CCC including possibility of fertility-sparing surgery, and the chemotherapy for CCC disease.

Abstract
AIM Several previous reports showed that irinotecan hydrochloride plus cisplatin (CPT-P) was a candidate first-line chemotherapy regimen for clear cell adenocarcinoma of the ovary (CCC). However, long-term survival in CCC patients treated with CPT-P as first-line chemotherapy remains to be determined. The aim of the present study was to evaluate the long-term results of CPT-P as first-line chemotherapy for CCC. MATERIAL AND METHODS We performed a retrospective review of 31 patients with CCC who were treated with CPT-P between 1996 and 2004. RESULTS The median follow-up period was 91 months. The estimated 8-year overall survival (OS) rate in all patients was 64.5%, while the rate in 18 stage I, 21 stage I/II, and 10 stage III/IV patients was 88.9%, 85.7%, and 20.0%, respectively. The estimated 8-year OS rate in patients with pT1/pT2 disease was 87.0%, while the 3-year OS rate in patients with pT3 disease was 0%. Univariate analysis using the log-rank test revealed that Eastern Cooperative Oncology Group performance-status 1, pT3 stage, and presence of residual disease (stage II-IV) were significantly correlated with shortened patient survival. Multiple regression analysis revealed that pT3 predicted worse OS in patients with CCC than pT1 (P<0.001) or pT2 disease (P < 0.005). CONCLUSION The long-term results suggest CPT-P as a candidate in first-line chemotherapy for CCC in not only stage I, but also in optimally debulked stage II-IV patients with pT1/pT2 disease.

Abstract
BACKGROUND The aim of this phase II study was to evaluate the efficacy and toxicity of docetaxel and irinotecan combination chemotherapy in patients with ovarian cancer refractory and resistant to both platinum and taxan treatment. PATIENTS AND METHODS Patients who had been treated with platinum and paclitaxel but whose ovarian cancer progressed or recurred within 6 months of treatment (n = 41) received docetaxel 60 mg/m(2) (day 1) and irinotecan 60 mg/m(2) (days 1, 8), repeated every 21 days [Japan Gynecologic Oncology Group (JGOG) study 3015] or every 28 days [West Japan Gynecologic Oncology Group (WJGOG) study 002] until disease progression was observed or unacceptable toxicity. Sixteen patients had platinum/paclitaxel-refractory disease, and 25 patients had platinum/paclitaxel-resistant disease. RESULTS Thirty-two patients were available for determination of the clinical response. The overall response rate [complete response (CR) + partial response (PR)] was 6.3%, and the disease control rate (CR + PR + stable disease) was 34.4%. Among the 23 patients with resistant tumor, the disease control rate was 47.8%. Ten patients with refractory tumor showed a 10% disease control rate. The median progression-free interval was 12.1 weeks and the median overall survival time was 45.3 weeks. The major toxic adverse effect was neutropenia (grade 4, 56.1%), but the incidence of neutropenic fever was less frequent (4.9%). Neurotoxicity and gastro-intestinal toxicity were mild. CONCLUSION Among our patients, a combination of docetaxel and irinotecan was well tolerated. However, this combination may not be a beneficial option for patients with platinum-refractory and -resistant ovarian cancer in terms of response rate and survival.

Abstract
PURPOSE The objective of this study was to evaluate the antitumor efficacy of trabectedin in clear cell carcinoma (CCC) of the ovary, which is regarded as an aggressive, chemoresistant, histologic subtype. EXPERIMENTAL DESIGN Using 6 human ovarian cancer cell lines (3 CCC and 3 serous adenocarcinomas), the antitumor effects of trabectedin were examined in vitro, and we compared its activity according to histology. We next examined the antitumor activity of trabectedin in both cisplatin-resistant and paclitaxel-resistant CCC cells in vitro. Then, the in vivo effects of trabectedin were evaluated using mice inoculated with CCC cell lines. Using 2 pairs of trabectedin-sensitive parental and trabectedin-resistant CCC sublines, we investigated the role of mTOR in the mechanism of acquired resistance to trabectedin. Finally, we determined the effect of mTOR inhibition by everolimus on the antitumor efficacy of trabectedin in vitro and in vivo. RESULTS Trabectedin showed significant antitumor activity toward chemosensitive and chemoresistant CCC cells in vitro. Mouse xenografts of CCC cells revealed that trabectedin significantly inhibits tumor growth. Greater activation of mTOR was observed in trabectedin-resistant CCC cells than in their respective parental cells. The continuous inhibition of mTOR significantly enhanced the therapeutic efficacy of trabectedin and prevented CCC cells from acquiring resistance to trabectedin. CONCLUSION Trabectedin is a promising agent for CCC as a first-line chemotherapy and as a second-line treatment of recurrent CCC that had previously been treated with cisplatin or paclitaxel. Moreover, trabectedin combined with everolimus may be more efficacious for the management of CCC.

Abstract
INTRODUCTION Paclitaxel plus carboplatin (TC) is generally considered to be the "gold standard" regimen for treatment of epithelial ovarian carcinomas. Little data are available, however, on the use of this regimen in patients with clear cell adenocarcinoma of the ovary (CCC). Combination chemotherapy with irinotecan hydrochloride plus cisplatin has been reported to be effective for primary and recurrent or resistant CCC. We compared these 2 combinations in patients with CCC. METHODS Patients (n = 99) with CCC were randomly assigned to receive either 180 mg/m2 paclitaxel on day 1 plus AUC 6 mg/mL x minute carboplatin on day 1 every 21 days (TC arm) or 60 mg/m2 irinotecan hydrochloride on days 1, 8, 15 plus 60 mg/m2 cisplatin on day 1 every 28 days (CPT-P arm). RESULTS Percentages of patients receiving the scheduled 6 cycles of chemotherapy in the TC and CPT-P arms were 70.8% and 72.0%, respectively. Although toxicity was well tolerated in both arms, the toxicity profile of each arm differed. Progression-free survival (PFS) showed no significant difference between the 2 treatment groups. Because there were more patients with large residual disease in the CPT-P arm, we performed a subset analysis by removing those patients, and then compared the PFS with that of patients without residual disease or with residual disease less than 2 cm. The PFS tended to be longer in the CPT-P group, although the difference was not statistically significant. CONCLUSIONS A phase III randomized trial is required to elucidate the effectiveness of CPT-P combination chemotherapy for CCC.

Abstract
To make an overview of the current status of gynecologic cancer in Japan, we reviewed the recent incidence of cervical, endometrial, and ovarian cancer in Japanese women. The incidence of all three cancers has increased, but trends differ respectively. In age specific cancer site distribution data, the uterus and ovary are leading sites of high incidence among Japanese women younger than 40 years of age. Therefore, fertility sparing cancer treatment has received much attention. Several multicenter clinical trials have been done by Japanese groups, and some excellent evidence has been collected for endometrial and ovarian cancer. A promising international collaboration trial for ovarian clear cell carcinoma is also underway at the present time.

Abstract
Ovarian cancer remains one of the most difficult gynecologic cancers to treat, owing to its aggressive biology and high relapse rate, as well as the toxic side effects of available chemotherapeutic agents used to treat recurrent disease. Topoisomerase I inhibitors, including topotecan and irinotecan, are some of the most effective and tolerable treatment options for recurrent ovarian cancer. The ideal dosing, timing of administration, role in combination with other chemotherapies or biologics and potential role in up-front therapy remains an area of active research. This article reviews the mechanism of action of topoisomerase I inhibitors and the efficacy, dosing, schedule and toxicity for topotecan, irinotecan, 9-nitrocamptothecin, DX-8951 and 9-aminocamptothecin. Conclusions include a discussion of future avenues of research and ongoing projects.

Abstract
BACKGROUND Irinotecan hydrochloride, a topoisomerase I inhibitor, has been preliminarily recognized as an effective agent against clear cell carcinoma of the ovary (CCC), but there are few clinical data. Our aim was to compare progression-free survival (PFS) between patients treated with irinotecan hydrochloride and cisplatin (CPT-P) and those with treated with paclitaxel and carboplatin (TC). METHODS One hundred and seventeen patients at International Federation of Gynecology and Obstetrics (FIGO) stages Ic (ascites/malignant washing) - IV were identified by scanning the medical records of ten Japanese hospitals. After complete surgical staging procedures including lymphadenectomy, 35 patients received CPT-P and 82 patients received TC. The PFS and overall survival of the two groups were compared using the Kaplan-Meier method. RESULTS There was no significant difference in median age, performance status, FIGO stage, rate of optimal cytoreduction, or follow-up period between the CPT-P and TC groups. Two-year and 5-year PFS was 48% and 40%, respectively, in the TC group and 55% and 55%, respectively, in the CPT-P group (P = 0.31). Multiple regression analysis revealed that only residual tumor was an independent prognostic factor for PFS (P < 0.01). CONCLUSION CPT-P showed a potential therapeutic effect, at least no less than that of TC therapy. Although there was no significant survival benefit in the present retrospective analysis, we recommend that the CPT-P regimen be evaluated in a larger, prospective, clinical trial.

Abstract
The aim of this study was to evaluate the efficacy and toxicity of irinotecan and doxorubicin in the treatment of patients with early recurrent or platinum-refractory ovarian cancer. Nineteen woman from five different institutions were treated. Two patients had platinum-refractory cancer, 11 had platinum-resistant disease, and 6 had platinum-sensitive tumors. An intravenous infusion of Irinotecan (50 mg/m(2)) was given on days 1, 8, and 15, while doxorubicin (40 mg/m(2)) was administered as an intravenous bolus on day 3. This treatment schedule was repeated every 4 weeks. Among the 13 patients defined as having platinum-refractory/platinum-resistant disease, 4 patients achieved a clinical response (30.8%, 95% CI: 9.1-61.4), while only one of 6 patients defined as having platinum-sensitive disease achieved a clinical response (16.7%, 95% CI: 0.4-64.1). Leukopenia and neutropenia were the major dose-limiting toxicities. Grade 3 or 4 leukopenia and neutropenia were noted in 24 (48%) and 33 (66%) of the courses, while febrile neutropenia occurred in 2 courses. Five patients (26%) had grade 2 or worse diarrhea during 7 courses. Our data demonstrated that this regimen might be comparable to standard approved agents in patients with early recurrent or platinum refractory ovarian cancer.

Abstract
We conducted the present study to investigate whether and how chemosensitivity can be determined by means of genetic diagnosis using drug-resistance genes in patients with epithelial ovarian cancer. A total of 75 patients who had epithelial ovarian cancer with measurable lesions were entered into this study. Thirty-three patients received first-line chemotherapy, consisting of paclitaxel and carboplatin (TJ). Forty-two patients received second-line chemotherapy, 22 received EP therapy consisting of etoposide and cisplatin (CDDP), and 20 received irinotecan (CPT-11) and CDDP (CPT-11/CDDP) therapy. Tumor samples were obtained before chemotherapy. MessengerRNA expressions of the multidrug-resistance (MDR)-1 gene, MDR-associated protein-1 (MRP-1), topoisomerase (topo) I, and topo IIalpha were measured by real-time reverse transcription-polymerase chain reaction. The cutoff values of each gene were determined by the receiver operating characteristic curve. MDR-1 expression was significantly higher in patients who did not respond to TJ therapy. The expression of topo IIalpha was significantly higher in patients who did respond to EP therapy. The expression of topo I was significantly higher in patients who did respond to CPT-11/CDDP. MRP-1 expression did not differ between responders and nonresponders in all regimens. The cutoff value was 80 for MDR-1, 90 for topo IIalpha, and 200 for topo I. Next, to evaluate genetic diagnosis, 31 patients were newly added. The accuracy of this genetic diagnosis for chemosensitivity was 85.7% for TJ, 77.8% for EP, and 100.0% for CPT-11/CDDP therapy. The present study suggests that genetic diagnosis may be useful to determine chemosensitivity in patients with epithelial ovarian cancer.

Abstract
OBJECTIVE Clear cell carcinoma of the ovary is an aggressive tumor characterized by relative chemoresistance and a poor prognosis. The purpose of this study was to review our experience with recurrent clear cell carcinoma of the ovary to evaluate its responsiveness to systemic cytotoxic and hormonal agents. METHODS All patients diagnosed with clear cell carcinoma of the ovary seen at our institution between 1990 and 2002 were identified and their medical records reviewed. Eligibility criteria were: 1) primary diagnosis of clear cell carcinoma of the ovary, 2) measurable recurrent disease, 3) treatment of recurrent disease with 1 or more systemic regimens, and 4) adequate clinical information. End points were clinical response, progression-free survival, and overall survival. RESULTS Fifty-one patients treated for recurrent clear cell carcinoma were identified. The patients received a total of 105 regimens (344 cycles of therapy). Among patients with platinum-sensitive disease (n=22 regimens), 2 patients (9%) had partial responses to retreatment with carboplatin plus paclitaxel, and 4 (18%) had stable disease. Among patients with platinum-resistant disease (n=83 regimens), only 1 patient (1%) had a partial response - to gemcitabine - and 1 patient had stable disease in response to 2 different regimens-paclitaxel and gemcitabine. The median progression-free survival was 8 months, and the median overall survival was 18 months. CONCLUSION Our findings suggest that recurrent clear cell carcinoma of the ovary is particularly chemoresistant. A continued search for more active, targeted agents is warranted.

Abstract
Chemotherapy after surgical debulking represents an essential component of treatment for patients with advanced ovarian cancer. Three quarters of patients respond very well to initial treatment with platinum-containing drugs used either alone or in combination with a taxane, usually paclitaxel. With relapse rates exceeding 50% and median survival time of 2 years for patients after relapse, efforts are focused on treatment approaches to achieve and extend clinical complete remissions. These approaches include consolidation and maintenance therapy, intraperitoneal (IP) administration of cytotoxic agents, new combination chemotherapy regimens, development of new cytotoxic agents, and molecular-targeted therapies (beyond tumor DNA, the classical target of cytotoxic drugs). IP chemotherapy, which involves direct instillation of chemotherapy into the tumor site in the peritoneal cavity, is the focus of this review article. This article discusses studies involving new and emerging IP drugs for both first-line chemotherapy treatment of advanced ovarian cancer and recurrent platinum-sensitive ovarian cancer.

Abstract
Ovarian clear cell adenocarcinomas (OCCAs) account for <5% of all ovarian malignancies. Compared to other epithelial ovarian cancer (EOC) subtypes, when at an advanced stage, they are associated with a poorer prognosis and are relatively resistant to conventional platinum-based chemotherapy. By contrast, early-stage clear cell ovarian cancer carries a relatively good prognosis. Hence, there is a need to improve our understanding of its pathobiology in order to optimise currently available treatments and develop new therapeutic strategies. This review summarises the currently available literature regarding the pathogenesis of OCCA, its molecular genetic features and postulated molecular mechanisms that underlie its chemoresistant phenotype. Marked similarities with clear cell carcinomas of the kidney and endometrium have been noted by some investigators, raising interesting possibilities regarding novel therapeutic approaches. Unfortunately, most studies on OCCA have hitherto been hampered by insufficient sample sizes, leaving many key issues unresolved. It is envisaged that in the future, high-resolution genomic and gene-expression microarray studies incorporating larger sample sizes will lead to the characterisation of the key molecular players in OCCA biology, which may potentially lead to the identification of novel targets for therapeutic development.

Abstract
BACKGROUND The objectives of the current study were to determine the maximum tolerated dose (MTD) of irinotecan and carboplatin in combination, to evaluate the efficacy and toxicity of the combination in patients with advanced ovarian carcinoma who previously received platinum-containing chemotherapy, and to examine the pharmacokinetics and pharmacodynamics of both drugs by using the Chatelut formula. METHODS Patients with advanced ovarian carcinoma who previously received platinum-containing chemotherapy were treated with a combination of irinotecan and carboplatin. Carboplatin was administered as a 60-minute intravenous infusion on Day 1 and was followed by irinotecan, which was administered as a 90-minute intravenous infusion on Days 1, 8, and 15. Six dose levels of irinotecan (in mg/m(2))/carboplatin (mg . mL/min) were planned: 50 mg/m(2)/4 mg . mL/minute, 60 mg/m(2)/4 mg . mL/minute, 50 mg/m(2)/5 mg . mL/minute, 60 mg/m(2)/5 mg . mL/minute, 50 mg/m(2)/6 mg . mL/minute, and 60 mg/m(2)/6 mg . mL/minute. The carboplatin dosage was calculated by using the Chatelut formula. Treatment was repeated at 28-day intervals. RESULTS In total, 19 patients in cohorts of 3 to 5 patients received irinotecan and carboplatin at 5 dose levels. The dose-limiting toxicities were Grade 4 neutropenia and Grade 4 thrombocytopenia. The MTD of the irinotecan/carboplatin combination was 60 mg/m(2)/5 . mg mL/minute. Partial responses were observed at higher dose levels. Pharmacologic studies demonstrated that administration of the dosage estimated with the Chatelut formula instead of the Chatelut formula with adjustment for serum creatinine resulted in a slightly excessive dose of carboplatin. CONCLUSIONS The recommended dose for the Phase II study was irinotecan 60 mg/m(2) on Days 1, 8, and 15 with carboplatin 5 mg/mL . minute on Day 1 repeated every 4 weeks.

Abstract
The aim of this study was to examine the level of activity of irinotecan hydrochloride (CPT-11) and mitomycin-C (MMC) combination chemotherapy in a patient population with platinum-refractory ovarian cancer. Patients received CPT-11 (140 mg/m2) in combination with MMC (7 mg/m2) on days 1, 15, 29 until disease progression, unacceptable toxicity developed, or they elected to discontinue treatment. Overall, 61 cycles of CPT-11/MMC chemotherapy were delivered to 13 patients. The major toxicity with this regimen was neutropenia, which was brief and reversible. The incidences of grade 3 and 4 neutropenia were 46% (6/13) and 15% (2/13), respectively. The nonhematological toxicities were generally mild and well tolerated. Of the 13 patients, 4 (31%) experienced an objective response (1 CR, 3 PRs). Among responders, the median duration of response was 30 weeks (range, 12 to 292+ weeks). The median time to progression for the 13 patients who received treatment on this trial was 24 weeks (range, 8 to 292+ weeks), with a median survival of 36 weeks (range, 20 to 292+ weeks). This preliminary study shows that the combination of CPT-11 and MMC appears to be an active regimen in patients with refractory ovarian cancer.

Abstract
BACKGROUND Irinotecan is a selective inhibitor of topoisomerase I, an enzyme part of the replication and transcription system of DNA. Irinotecan is employed, with different modalities, in the treatment of metastatic colorectal cancer, and recently it has been officially approved in association with fluorouracil (FU) and leucovorin (LV) as a first-line option in metastatic colorectal cancer. RESULTS One of the problems linked to the administration of this drug is the high intestinal toxicity, which constitutes its dose limiting toxicity (DLT). In routine practice, loperamide is employed as symptomatic drug for the treatment of CPT-11-induced diarrhoea, but is not completely adequate to control the problem. The role of the intestinal bacterial microflora in the pathogenesis of CPT-11-induced intestinal toxicity has been recently discovered. The active metabolite of CPT-11, SN38, is generated from CPT-11 by sieric carboxylesterase, and subsequently conjugated to SN38-G by hepatic UDP-glucuronyltransferase. SN38-G is the inactive metabolite of CPT-11 and is excreted into the small intestine, from which it is eliminated in the faeces. Some studies have shown the ability of intestinal bacterial beta-glucoronidases to transform SN38-G into SN38, causing direct damage to the intestinal mucosa. Thus, alternative strategies such as intestinal alkalinization and anti-cyclooxygenase 2 (COX-2) therapy have been explored. CONCLUSIONS In this review, we will illustrate the mechanisms which cause the CPT-11-induced diarrhoea and the potential measures available to prevent it.

Abstract
PURPOSE To evaluate the efficacy and toxicity of irinotecan in patients with metastatic platinum-resistant or platinum-refractory epithelial ovarian cancer or primary peritoneal cancer. PATIENTS AND METHODS Thirty-one patients with measurable disease were enrolled in our study at The University of Texas M.D. Anderson Cancer Center. Twenty-five of these patients were treated with irinotecan at a dose of 300 mg/m2 intravenously for 90 minutes every 3 weeks; the remaining six patients were treated with 250 mg/m2 because their age was greater than 65 years. Median age was 57 years (range, 38 to 74 years). The majority (84%) had a Zubrod performance status of 0. All patients were evaluated for irinotecan toxicity, and 29 (94%) were evaluable for response. RESULTS The overall response rate was 17.2%. One patient (3%) had a complete response, four (14%) had partial responses, 14 (48%) had stable disease, and 10 had (35%) disease progression. Median progression-free survival was 2.8 months (range, 1.1 to 16 months), median duration of response was 1.4 months (range, 0.7 to 10.1 months); median survival from primary diagnosis was 24.3 months (range, 6.5 to 85.7 months); and median survival from initiation of irinotecan was 10.1 months (range, 2.3 to 34 months). Major toxicities included fatigue (16 patients), neutropenia (11 patients), diarrhea (nine patients), nausea (10 patients), and anorexia (seven patients). Eleven patients required dose reductions because of these toxicities. No treatment-related deaths occurred. CONCLUSION Irinotecan has moderate efficacy and substantial toxicity in patients with metastatic platinum-resistant or platinum-refractory epithelial ovarian or primary peritoneal cancer.

Abstract
To reduce the side-effects of irinotecan (CPT-11) while maintaining its anti-cancer effects against recurrent ovarian carcinomas, we devised a novel administration schedule for CPT-11 single chemotherapy. It consisted of an initial dose of 70 mg/m2, followed by increasing the dose to 100 mg/m2 every 10 days (three times per month) for 9 cycles. Nineteen patients with refractory or recurrent ovarian carcinomas were treated. In comparison with a late phase II study of single CPT-11 chemotherapy in Japan (100 mg/m2 every 7 days; four times per month), the number of patients who suffered from leukocytopenia and diarrhea higher than grade 3 was significantly lower with our new method (36.8 versus 57.1%; P < 0.01 and 0 versus 19.2%; P < 0.001, respectively). The total response rate was 26% (5/19). This rate was almost equal to a late phase II study. We suggest that our new protocol of single CPT-11 administration should be available clinically to all patients for reducing the side-effects while maintaining its anti-cancer effects. CPT-11 is useful in patients with refractory ovarian carcinomas as a second- or third-line chemotherapy.

Abstract
Since its approval in the United States in 1996, irinotecan (CPT-11, Camptosar, Pharmacia Corp.; Peapack, NJ) has undergone extensive clinical evaluation. In the past five years, the focus of development has evolved from evaluation of single-agent activity in refractory disease settings to evaluation of front-line irinotecan-based combination chemotherapy regimens and integration of irinotecan into combined modality regimens. Important studies have been performed clarifying the role of irinotecan in treating colorectal and other gastrointestinal cancers, small cell and non-small cell lung cancer, and a variety of other malignancies. Preclinical studies performed in conjunction with these clinical trials have also provided significant insights into the pharmacology, metabolism, mechanisms of resistance, and molecular determinants of response. This review summarizes that progress, focusing on the achievements of the past five years.

Abstract
PURPOSE To assess the feasibility, pharmacokinetic interaction, and possible sequence-dependent effects of the irinotecan/cisplatin combination given every 3 weeks, and to assess the influence of additional granulocyte colony-stimulating factor (G-CSF) on the hematologic toxicity. PATIENTS AND METHODS Patients who had received no more than one prior combination chemotherapy regimen or two single-agent regimens were entered. Treatment consisted of a 90-minute irinotecan infusion followed by a 3-hour cisplatin infusion on day 1, with cycles repeated once every 3 weeks. After the maximum-tolerated dose was determined, the sequence of administration was reversed. In a separate cohort of six patients, we assessed the effect of G-CSF on the experienced hematologic toxicity and dose-intensity. Irinotecan doses ranged from 175 to 300 mg/m(2) and cisplatin doses ranged from 60 to 80 mg/m(2). RESULTS Fifty-two patients entered the study; one was not eligible, and two were not assessable for response. Twenty-five patients were pretreated, and 26 were not. Fifty-one patients received a total of 223 courses. The dose-limiting toxicity was a combination of neutropenic fever, diarrhea, and fatigue at a dose level combining irinotecan 300 mg/m(2) with cisplatin 80 mg/m(2). Neutropenia was common (grades 3 to 4, 68%). Irinotecan pharmacokinetics were linear over the dose range studied. No sequence-dependent side effects were observed. Tumor responses included three complete responses and eight partial responses. CONCLUSION For phase II studies, we recommend irinotecan 260 mg/m(2) combined with cisplatin 80 mg/m(2) once every 3 weeks for chemotherapy-naive patients in good physical condition, and irinotecan 200 mg/m(2) combined with cisplatin 80 mg/m(2) for other patients.

Abstract
BACKGROUND AND OBJECTIVES Irinotecan hydrochloride (CPT-11) is one of the camptothecin analogues that has shown a broad spectrum of strong antitumor effectiveness against various cancers, including colorectal cancer. In order to promote the clinical response of chemotherapy for colorectal cancer using CPT-11, one of the most effective strategies is to use it in combination with other anticancer agents. In the present study, anticancer effects after combining CPT-11 and other antitumor agents were determined by a 3-(4,5-di-methylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay of colorectal cancer cells, especially freshly isolated cancer cells. METHODS Freshly isolated cancer cells from 20 patients with colorectal cancer and the established colon cancer cell lines were used in this study. The augmentation of the antitumor effectiveness of 7-ethyl-10-hydroxy-CPT (SN-38) was analyzed in combination with other anticancer agents. Furthermore, the antitumor effectiveness using lower concentrations of anticancer agents was measured to understand the mechanism of the augmentation. RESULTS The percent inhibition of SN-38 in combination with cisplatin (CDDP) and mitomycin revealed a high anticancer effect compared with each anticancer agent alone for freshly isolated rectal cancer. CDDP also had a synergistic effect in combination with SN-38 according to the fractional product concept. At lower than plasma peak concentrations of SN-38, the anticancer effects were augmented in combination with lower concentrations of CDDP for freshly isolated colorectal cancer. This augmentation showed a strong synergistic effect. CONCLUSIONS These results may be supportive to ongoing clinical studies of chemotherapy by using CPT-11 and CDDP for advanced colorectal cancer.

Abstract
The aim of the present study was to clarify the relationship between topoisomerase-I (topo-I) activity and sensitivity to second-line chemotherapy consisting of cisplatin and camptothecin-11 (CPT-11) in patients with ovarian cancer. Thirty Japanese women with relapsed epithelial ovarian cancer who received treatment at Tottori University Hospital or Kurume University Hospital between 1992 and 1997 were included in this study. All patients had initially undergone chemotherapy consisting of cisplatin, doxorubicin and cyclophosphamide (CAP). All subjects exhibited measurable lesions and received second-line chemotherapy consisting of 50 to 60 mg/m(2) CPT-11 on days 1, 8 and 15 and 60 mg/m(2) cisplatin on day 1. Tumor samples were obtained in the period between initial and second-line chemotherapy. Topo-I activity was assayed by relaxation of supercoiled plasmid substrate DNA. Of the 30 patients, 18 responded to second-line chemotherapy and 12 did not. We found no significant difference in patient characteristics in responders and non-responders. The interval from the end of the initial course of chemotherapy to the beginning of the second-line chemotherapy did not significantly differ in the 2 groups. The minimum amount of extraction showing complete DNA relaxation in non-responders was significantly greater than that in responders (201.7 +/- 92.5 vs. 124.1 +/- 59.4 ng; p = 0.0164). In 8 cases whose samples could be obtained before and after CAP, the amount of protein significantly decreased after CAP therapy (286.4 +/- 142.1 vs. 138.5 +/- 97.8 ng; p = 0.0294). Topo-I activity, which is enhanced by CAP therapy, can play an important role in sensitivity to CPT-11.

Abstract
BACKGROUND Ovarian clear cell adenocarcinoma is known to have poorer prognosis than ovarian serous cystadenocarcinoma. Cyclophosphamide plus cisplatin has been the standard therapy for ovarian cancer, but ovarian clear cell adenocarcinoma dose not respond to this therapy. The treatment for ovarian clear cell adenocarcinoma has not been established. We planned a pilot study of CPT-11 and cisplatin for the treatment of ovarian clear cell adenocarcinoma. METHODS First, three patients were administered 70 mg/m2 of cisplatin intravenously on day 1 and 60 mg/m2 of CPT-11 intravenously on days 1, 8 and 15. Treatment was repeated every 4 weeks. Other patients were administered 75 mg/m2 of cisplatin intraperitoneally on day 1 and 60 mg/m2 of CPT-11 intravenously on days 1, 8 and 15. Treatment was repeated every 4 weeks. RESULTS A total of 10 patients were entered in this study and a total of 43 courses were administered. 1 CR, 1 PR and 1 PD were observed in patients with measurable lesion. Grade 3 leukopenia was experienced in seven patients, grade 3 thrombocytopenia in two and grade 3 anemia in five. Grade 3 liver toxicity was observed in one patient and grade 3 diarrhea in one patient. No grade 4 toxicity was experienced. CONCLUSION CPT-11 plus cisplatin is feasible and has efficacy for ovarian clear cell adenocarcinoma. This regimen should be explored in a phase II study.
