Abstract
Background: A phase III trial was conducted to determine whether neoadjuvant chemotherapy (NACT) before radical surgery (RS) improves overall survival. Methods: Patients with stage IB2, IIA2, or IIB squamous cell carcinoma of the uterine cervix were randomly assigned to receive either BOMP (bleomycin 7 mg days 1–5, vincristine 0.7 mg m−2 day 5, mitomycin 7 mg m−2 day 5, cisplatin 14 mg m−2 days 1–5, every 3 weeks for 2 to 4 cycles) plus RS (NACT group) or RS alone (RS group). Patients with pathological high-risk factors received postoperative radiotherapy (RT). The primary end point was overall survival. Results: A total of 134 patients were randomly assigned to treatment. This study was prematurely terminated at the first planned interim analysis because overall survival in the NACT group was inferior to that in the RS group. Patients who received postoperative RT were significantly lower in the NACT group (58%) than in the RS group (80% P=0.015). The 5-year overall survival was 70.0% in the NACT group and 74.4% in the RS group (P=0.85). Conclusion: Neoadjuvant chemotherapy with BOMP regimen before RS did not improve overall survival, but reduced the number of patients who received postoperative RT.

Abstract
Clear cell carcinoma (CCC) of the ovary has been recognized to show resistance to anticancer agents in the first-line chemotherapy. Our aim was to evaluate the effect of second-line chemotherapy in a retrospective study. A total of 75 patients diagnosed with CCC and treated between 1992 and 2002 in collaborating hospitals were reviewed. Criteria for the patients' enrollment were 1) diagnosis of pure-type CCC at the initial operation, 2) treatment after one systemic postoperative chemotherapy, 3) measurable recurrent or refractory tumor, 4) at least two cycles of second-line chemotherapy and assessable for the response, and 5) adequate clinical information. Regimens of first-line chemotherapy were conventional platinum-based therapy in 33 cases, paclitaxel plus platinum in 24 cases, irinotecan plus platinum in 9 cases, and irinotecan plus mitomycin C in 7 cases. Treatment-free periods were more than 6 months in 24 cases (group A) and less than 6 months in 51 cases (group B). In group A, response was observed in two cases (8%): one with conventional platinum therapy and another with irinotecan plus platinum. In group B, three cases (6%) responded: two with platinum plus etoposide and one case with irinotecan plus platinum. Median overall survival was 16 months in group A and 7 months in group B (P = 0.04). These findings suggest recurrent or resistant CCC is extremely chemoresistant, and there is only small benefit of long treatment-free period in CCC patients. Another strategy including molecular-targeting therapy is warranted for the treatment of recurrent or refractory CCC.

Abstract
A retrospective analysis was performed to evaluate the clinical characteristics and prognostic factors in the patients with clear cell carcinoma (CCC) of the ovary. After central pathological review and scanning of the medical records of nine Japanese institutions between 1992 and 2003, a total of 254 patients with CCC of the ovary were enrolled in the present study. Mean age was 52.4 years (range 23–73 years). Tumours were 13% (33/254) stage Ia, 36% (92/254) stage Ic, 13% (33/254) stage II, 30% (80/254) stage III, and 6% (16/254) stage IV. Five-year progression-free survival and overall survival was 84 and 88% in stage I, 57 and 70% in stage II, 25 and 33% in stage III and 0 and 0% in stage IV, respectively. Retroperitoneal lymph node metastasis was observed in 9% in pT1a tumours, 7% in pT1c tumours, 13% in pT2 tumours, and 58% in pT3 tumours, respectively. There was no survival benefit according to chemotherapeutic differences in the patients who received complete surgical staging procedures and conventional chemotherapy. Peritoneal cytological status was an independent prognostic factor in stage Ic patients (P=0.03) and only residual tumour diameter was an independent prognostic factor in stage III, IV patients (P=0.02). Our results suggest that cytoreductive surgery resulting in no residual tumour only could improve the prognosis of advanced CCC patients.

Abstract
15029 Background: The Japanese Society of Gynecologic Oncology started a training program for the subspecialty of board certified gynecologic oncologists in 2005. This study aimed to assess the attitude of Japanese gynecologists for the treatment of ovarian cancer in pre-gynecologic oncologist era. Methods: The JGOG distributed a survey to 217 member institutions in January 2005. The principal investigator (PI) of each institution answered 33 questionnaires regarding diagnostic, surgical and chemotherapy issues. The survey was returned from 156 institutions (71.9%). Results: Hospital settings were general (44%), academic (44%), Cancer Center (8%), or private (4%). Only two of PIs were medical oncologists and rests of them were gynecologists. As the staging procedure in early ovarian cancer, 67% institutions do systemic pelvic lymphadenectomy (LNX) but 22% do only sampling. For the paraaortic nodes, 36% do systemic LNX and 10% do sampling below renal vein, and 14% do LNX and 12% do sampling below inferior mesenteric artery. However, intraabdominal explorations such as multiple peritoneal biopsies have been done only less than 30% except for omentectomy (90%). With regard to the surgery for advanced ovarian cancer, 57% institutions do not do any intestinal resection and anastomosis during the primary surgery. Among them 7% of institutions prefer neoadjuvant chemotherapy (no debulking at all) for advanced ovarian cancer. However, 84% of the institutions do interval debulking and 57% of them are quite aggressive for the procedure. These results demonstrate the high expectation that chemotherapy may reduce the aggressiveness of surgery for advanced ovarian cancer. In terms of chemotherapy for the high-risk early and advanced ovarian cancer, taxane plus platinum is the most used regimen (93–95%). However, 45% of institutions prefer different regimen for clear cell carcinoma. CPT-11 is the most used (88.6%). Intraperitoneal chemotherapy has been performed in 28.2% of institutions. 37.2% of institutions do consolidation chemotherapy. Conclusions: This is an important base-line information to assess the pattern of care for ovarian cancer patients in the era before gynecologic oncologist subspecialty is applicable in Japan. No significant financial relationships to disclose.

Abstract
5013 Background: NAC may represent an alternative to conventional RH for locally advanced cervical cancer. We compared NAC followed by RH with RH for bulky stage I/II cervical cancer. Methods: Patients (pts) with stage IB2, IIA (> 4 cm), or IIB squamous cell carcinoma of the uterine cervix were randomly assigned to receive either BOMP (bleomycin 7mg day 1–5, vincristine 0.7mg/m2 day 5, mitomycin 7mg/m2 day 5 and cisplatin 14 mg/m2 day 1–5,) q21 days, 2 to 4 cycles followed by radical hysterectomy (NAC arm) or undergo RH (RH arm). Pts with positive surgical margins, metastatic nodes, infiltration to parametrium, and/or deep myometrial invasion received postoperative irradiation. Eligibility included preserved organ function, aged 20–70, and Performance Status 0 or 1. Primary endpoint was overall survival (OS) to be compared by log-rank test. Assuming 100 eligible pts in each arm, the study had 80% power to detect a 15% increase in 5-year survival at 0.05 one-sided alpha. Results: 134 pts (67 NAC, 67 RH) were randomized between 12/01 and 08/05. The first planned interim analysis was performed in July 2005 using data from 108 pts registered as of 11/04. Data and Safety Monitoring Committee recommended to terminate the study because overall survival in NAC arm was inferior to that in RH arm (HR 2.11, multiplicity adjusted 99% CI 0.34 to 13.2) and the predictive probability of significant superiority using Spiegelhalter’s method of NAC arm was extremely low (6.4%). No increase of operability and no decrease of surgery-related morbidity were observed in NAC arm. Response Rate of NAC was 61% (33 of 54) using RECIST criteria. One-year progression-free survival and overall survival, updated as of 05/05, were 69.9% and 91.8% (95% CI 84.1–99.6) in NAC arm and 78.6% and 95.4% (95% CI 89.1–100) in RH arm respectively. Conclusions: Neoadjuvant chemotherapy with BOMP regimen followed by radical hysterectomy did not demonstrate clinical benefit, and conventional radical hysterectomy still remains to be a standard treatment option for bulky stage I/II cervical cancer.

Abstract
15020 Background: Retrospective analyses revealed that survival of ovarian cancer patients treated with NAC followed by IDS was comparable with those treated by standard treatment starting with primary debulking surgery. The purpose is to assess the safety and efficacy of the NAC setting treatment and also to know whether we can accurately diagnose the cancer by imaging studies, cytologic findings and tumor markers without diagnostic laparoscopy (DLS). Methods: The study was performed as a multi-institutional non-randomized phase II trial. Eligibility included stage III/IV müllerian carcinoma (MC) such as ovarian, tubal and peritoneal carcinomas diagnosed by imaging studies (CT and/or MRI), cytology of ascites, pleural effusions or fluids obtained by tumor centesis, CA125 >200 U/ml and CEA<20 ng/ml. After study enrollment, DLS is performed to confirm tumor origin, histology and stage. Four cycles of combination of paclitaxel (175 mg/m2, 3h) and carboplatin (AUC 6) are administered as NAC, followed by IDS and additional 4 cycles of chemotherapy. Primary endpoint is proportion of clinical complete remission (% cCR) with CA 125<20 U/ml among all stage III/IV MC confirmed by DLS (expected % cCR of 40% and threshold % cCR of 20%). Major secondary endpoint is positive predictive value (PPV) of clinical diagnoses concerning origin, histology and stage (expected PPV>90%, then DLS will be omitted in the next phase III study). The planned sample size was 56 eligibles, which gives 10% or lower Bayesian posterior probability that PPV is < 90% in case of three false positives. Results: Fifty six patients were enrolled between Jan/2003 and Feb/2004. All patients had accurate pre-DLS diagnosis concerning origin and histology. In 53 (PPV 94.6%) of 56 patients, tumor stage was accurately diagnosed. Twenty nine (62%) of 47 patients who underwent IDS had complete resection without residual tumors. Nineteen (%cCR 36%) among 53 patients with stage III/IV MC achieved cCR at completion of planned treatment. Conclusions: NAC starting without DLS followed by IDS for advanced MC is a promising treatment to be compared with the current standard treatment in a phase III study. [Table: see text]

Abstract
Retroviral vectors are the frequently applied gene delivery vehicles for clinical gene therapy, but specificity of the immunogenicity to the protein encoded by the inserted gene of interest is a problem which needs to be overcome. Here, we describe human cytotoxic T-lymphocyte (CTL) clones recognizing epitopes derived from the protein encoded by the retroviral vector backbone, which were established during the course of our attempts to generate CTLs against cytomegalovirus (CMV) or human papilloma virus (HPV) in vitro. In the case of healthy CMV-seronegative donors, CTL lines specific for retrovirally transduced cells were generated in four out of eight donors by stimulating CD8 T cells with CD40-activated B (CD40-B) cells retrovirally transduced with CMV-pp65. Two CTL clones derived from one of the CTL lines were found to recognize epitopes from gag in the context of HLA-B(*)4403 and -B(*)4601, respectively. Similarly, an HLA-B(*)3501-restricted CTL clone from a cervical cancer patient recognized an epitope located in the junctional regions of the gag and pol sequences. These results show that polypeptides encoded by components of the retroviral vector backbone are in fact immunogenic, generating CTLs in vitro in human cells. Thus, potential CTL responses to retroviral products should also be considered in clinical settings.

Abstract
PURPOSE Associations of tumor diameter in epithelial ovarian cancer with clinical and pathological prognostic variables were investigated. METHODS The clinical and pathological records of 233 patients diagnosed with epithelial ovarian cancer and treated at Aichi Cancer Center were studied. RESULTS Tumor diameters of 44 patients (18.9%) were < 5 cm, 90 (38.6%) were 5-10 cm, and 99 (42.5%) were > 10 cm. While 90.9% (40/44) of < 5 cm tumors presented with FIGO stage III-IV, 40.4% (40/99) of > 10 cm tumors were advanced. Intra-abdominal disease was also significantly associated with tumor diameter, although differences among lymph-node status were not significant. The incidence of serous and endometrioid adenocarcinoma in < 5 cm tumors were 75.0% (33/44) and 11.4% (5/44), respectively, while those of > 10 cm tumor were 32.3% (32/99) and 17.2% (17/99). Multivariate analysis revealed that tumor diameter was not an independent prognostic variable. CONCLUSION Tumor diameter of ovarian cancer is associated closely with histological subtypes and stage of disease, especially intra-abdominal disease.

Abstract
Thermolysin is remarkably activated in the presence of high concentrations (1-5 M) of neutral salts [Inouye, K. (1992) J. Biochem. 112, 335-340]. The activity is enhanced 13-15 times with 4 M NaCl at pH 7.0 and 25 degrees C. Substitution of the active site zinc with other transition metals alters the activity of thermolysin [Holmquist, B. and Vallee, B.L. (1974) J. Biol. Chem. 249, 4601-4607]. Cobalt is the most effective among the transition metals and doubles the activity toward N-[3-(2-furyl)acryloyl]-glycyl-L-leucine amide. In this study, the effect of NaCl on the activity of cobalt-substituted thermolysin was examined. Cobalt-substituted thermolysin, with 2.8-fold increased activity compared with the native enzyme, is further activated by the addition of NaCl in an exponential fashion, and the activity is enhanced 13-15 times at 4 M NaCl. The effects of cobalt-substitution and the addition of salt are independent of each other. The activity of cobalt-substituted thermolysin, expressed as k(cat)/K(m), is pH-dependent and controlled by at least two ionizing residues with pK(a) values of 6.0 and 7.8, the acidic pK(a) being slightly higher compared to 5.6 of the native enzyme. These pK(a) values remain constant in the presence of 4 M NaCl, indicating that the electrostatic environment of cobalt-substituted thermolysin is more stable than that of the native enzyme, the acidic pK(a) of which shifts remarkably from 5.6 to 6.7 at 4 M NaCl. Zincov, a competitive inhibitor, binds more tightly to the cobalt-substituted than to native thermolysin at pH 4.9-9.0, probably because of its preference for cobalt in the fivefold coordination. The cobalt substitution has been shown to be a favorable tool with which to explore the active-site microenvironment of thermolysin.

Abstract
BACKGROUND A multicenter, phase I study of combination therapy with paclitaxel and carboplatin for epithelial ovarian cancer was conducted to determine the safety and recommended dosages for Japanese women. METHODS Paclitaxel was administered intravenously over a 3-h period, followed by carboplatin administered intravenously over a 1.5-h period. A modified continual reassessment method (mCRM) was used in two treatment arms to establish the maximum tolerated dose (MTD) and recommended doses of the combination. In group A, the dose of paclitaxel (175 mg/m2) was constant and the dose of carboplatin was increased from 4 to 7 in terms of the target area under the plasma concentration-versus-time curve (AUC). In group B, the dose of carboplatin was constant (AUC 6) and paclitaxel was administered at two dose levels (160 and 175 mg/m2). In both groups, the carboplatin dose was limited to a maximum of 800 mg/body for each administration. RESULTS Because the calculated probability of toxicity was greatest at a dose of paclitaxel 175 mg/m2 and carboplatin AUC 7, this dose was designated the MTD in group A. Based on this result, treatment in group B was initiated at doses of paclitaxel of 160 mg/m2 and carboplatin AUC 6. While the dose of paclitaxel was escalated to 175 mg/m2, the safety of the combination was confirmed. The most frequent adverse effect was neutropenia, which resolved promptly with the appropriate use of granulocyte-colony stimulating factor (G-CSF). No other severe hematologic or nonhematologic toxicities were observed. CONCLUSIONS Our study demonstrated that the recommended dose for this combination regimen should be paclitaxel 175 mg/m2 plus carboplatin AUC 6 (maximum dose, 800 mg/body).

Abstract
The purpose of our study was to examine the menopausal state as an independent prognostic variable of endometrial cancer and determine the conditions under which the menopausal state would be an independent prognostic variable of such cancer. We studied the clinical and pathologic variables of 255 patients with invasive endometrial cancer. In comparisons of the clinicopathologic variables between menopausal states, obesity and deep myometrial invasion were found more frequently in older patients than in younger ones. Multivariate analysis performed on 255 cases with complete pathologic data identified menopausal state, cervical invasion, pelvic lymph node metastasis, and tumor grade as prognostic variables. Univariate analysis revealed that survival of older patients with FIGO pathologic stage Ib disease was significantly poorer than in younger patients, while there was no significant difference in the analyses of stage Ic or advanced disease beyond stage II. We conclude that menopausal state was an independent prognostic variable for patients with early endometrial cancer, but not for patients with advanced disease.

Abstract
OBJECTIVE The purpose of our study was to investigate a possible difference in ovarian metastasis between squamous cell carcinoma and adenocarcinoma of the uterine cervix and to confirm clinicopathological variables associated with the metastases. METHODS Clinical and pathological variables of 1064 patients with invasive squamous cell carcinoma and 240 with adenocarcinoma were studied. RESULTS Ovarian metastasis was found in 14 patients (1.3%) with squamous cell carcinoma and 15 (6.3%) with adenocarcinoma. The mean age of patients with ovarian metastasis of squamous cell carcinoma was 57.4 years, compared to 50.2 years for adenocarcinoma. Ovarian metastasis of adenocarcinoma was more likely to be visible (40.0%) and present in both ovaries (66.7%), while these two characteristics occurred in only 21.4 and 36.7% of patients with squamous cell carcinoma. A logistic regression analysis with clinical variables indicated that clinical stage beyond IIb was a significant variable of squamous cell carcinoma, and more than 30-mm tumor size was significant in adenocarcinoma. CONCLUSION The incidence of ovarian metastasis of adenocarcinoma of the uterine cervix was significantly higher than that of squamous cell carcinoma. The incidence of adenocarcinoma was associated more closely with tumor size than clinical stage, whereas it was more associated with clinical stage in squamous cell carcinoma. The results thus suggested that the differences in ovarian metastases were caused by the different characteristics of the two types of carcinoma.

Abstract
Thirty-nine patients with endometrioid adenocarcinoma (EA) and atypical hyperplasia (AH) of the endometrium who received conservative treatment to preserve fertility were collected from member institutions of the Japan Gynecologic Oncology Study Group. Twenty-nine and ten were originally diagnosed with EA without myometrial invasion and AH, respectively. We performed a central pathological review to make definite diagnoses, and the diagnosis of EA in 29 cases was changed to AH in ten, complex hyperplasia in three and atypical polypoid adenomyoma in three, and AH in ten was changed to EA in one and simple hyperplasia in one. Nine of 12 women (75%) with EA and 15 of 18 women (83%) with AH had an initial response to medroxyprogesterone acetate (MPA) treatment. Two of nine responders with EA later developed relapse, and one of them had metastasis to the left obturator lymph node. Two became pregnant, and one delivered one full-term infant. One of the responders with AH had a relapse in the endometrium. Five became pregnant, and four delivered four normal infants. The young women with endometrial carcinoma localized in the endometrium who wish to preserve fertility may be treated as successfully with MPA as those with AH.

Abstract
OBJECTIVE In the present study, we conducted a multicenter retrospective analysis to elucidate the prognostic factors of stage IV epithelial ovarian cancer. METHODS In November 1999, 24 Japanese institutions received questionnaires regarding stage IV epithelial ovarian cancer patients. Eligibility criteria included all patients with stage IV epithelial ovarian cancer who were surgically confirmed and initially treated in each institution between January 1990 and December 1997. Data were collected regarding age, performance status, tumor histologic subtype, site of metastasis, preoperative CA125, cytoreductive surgery, residual disease after cytoreductive surgery, and response to primary chemotherapy. Survival analysis and comparisons were performed by univariate and multivariate methods. RESULTS Two hundred twenty-five patients with stage IV ovarian cancer were identified. The median age of the patients was 54 years. The most common site of extraperitoneal disease was malignant pleural effusion (39.6%). Of the 225 patients who underwent an attempt at surgical debulking, 70 (31.1%) were optimally cytoreduced. Most patients received platinum-based combination chemotherapy for primary chemotherapy. In multivariate analysis, performance status, histology, and residual disease after cytoreductive surgery were independent prognostic predictors of outcome. The overall median survival for optimally debulked patients was 32 months compared to 16 months for suboptimally debulked patients (P < 0.0001, hazard ratio: 0.415). CONCLUSION Optimal surgical debulking, performance status, and histology appear to be important prognostic factors of survival in patients with stage IV epithelial ovarian cancer.

Abstract
BACKGROUND The clinical response, survival, and toxicity of a 3-h infusion of single-agent paclitaxel (175 mg/m2) for Japanese patients with recurrent ovarian cancer were investigated. We also examined whether or not cancer antigen (CA) 125 would be suitable as an indicator of the effects of the paclitaxel on ovarian cancer. METHODS Twenty-one patients clinically diagnosed as having recurrent ovarian cancer met the entry criteria, agreed to participate in this study, and received the treatment. RESULTS One hundred and twenty-six courses were administered to the 21 patients. One patient achieved a complete response, and 5 a partial response; the overall response rate was 35.3%. Using CA125 criteria, 42.1% of patients achieved a response. The median progression-free interval was 4.4 months, and the median overall survival time was 14.5 months. While hematological toxicity was not severe, 3 patients experienced severe peripheral neuropathy, and 2 patients experienced grade 4 myalgia/arthralgia. CONCLUSION The 3-h infusion of single-agent paclitaxel (175 mg/m2) was an effective treatment for patients with recurrent ovarian cancer. CA125 was a useful indicator of the response to the treatment. While peripheral neuropathy and the myalgia/arthralgia were severe, 3-h infusion of single-agent paclitaxel offers a promising treatment for recurrent ovarian cancer.

Abstract
OBJECTIVES The influence of the histology of adenocarcinoma on recurrence and survival for patients treated with radical hysterectomy and diagnosed as having pathologic stage Ib cervical cancer was investigated. METHODS Five hundred and nine patients (405 squamous cell carcinomas, 104 adenocarcinomas) with pathologic stage Ib cervical cancer treated initially at the Aichi Cancer Center between 1976 and 1995 were studied. RESULTS Multivariate analysis identified the prognostic variables as histology of adenocarcinoma, number of lymph nodes involved, and tumor size beyond 4 cm. Five-year overall survival and disease-free survival of patients with adenocarcinoma in the presence of lymph node metastasis were 63.2 and 47.4%, respectively, significantly poorer than for squamous cell carcinoma (83.6 and 80.6%; P < 0.001 and P = 0.002, respectively). These were not different in the absence of lymph node metastasis (adenocarcinoma, 93.9 and 92.7%; squamous cell carcinoma, 97.9% and 96.1%; P = 0.067 and P = 0.250, respectively). CONCLUSIONS The independent significant risk factors for the recurrence and survival of pathologic stage Ib cervical cancer were the presence of lymph node metastasis, large tumor size beyond 4 cm, and histology of adenocarcinoma. The prognosis of patients with adenocarcinoma was poorer than of patients with squamous cell carcinoma in the presence of lymph node metastasis, while the prognosis of pathologic stage Ib cervical cancer was equivalent when there was no metastasis.

Abstract
The purpose of this study was to investigate the influence of tumor size on pathologic variables and the prognosis of patients diagnosed as clinical stage IB cervical cancer. Five hundred sixty six patients with clinical stage IB cervical cancer treated surgically at the Aichi Cancer Center between 1976 and 1995 were studied. The incidence of pathologic variables that increased as tumors enlarged was unchanged beyond 4.0 cm. Although univariate analysis revealed that the prognosis worsened as a tumor enlarged, there was no significant difference in prognoses between 3.1-4.0 cm and 4.1-5.0 cm tumors. While multivariate analysis showed tumor size as an independent prognostic variable, there was no difference between the odd ratios of 3.1-4.0 cm and 4.1-5.0 cm tumors. Tumor size was an independently significant risk factor for the prognosis of clinical stage IB cervical cancer. While the definition of 4.0 cm as a cut-off point was useful as far as determining an association with pathologic variables, it may be an insufficient indicator of poor prognosis. The "bulky" tumors should be defined as clinical lesions greater than 5.0 cm, though few patients would have tumors that meet that criterion.

Abstract
We examined the subcellular localization of BRCA1 proteins using immunohistochemical staining with C-terminal (GLK-2 antibody) and N-terminal (Ab-2 antibody) monoclonal antibodies in 44 familial ovarian cancers. Among these, 24 cases were associated with 13 independent germ-line mutations of BRCA1, and loss of heterozygosity (LOH) at one or more BRCA1 microsatellite markers was found in all 21 informative tumors tested. With GLK-2 antibody, cytoplasmic staining was observed in 15 of 16 tumors (93.8%) with mutation in exon 11, and BRCA1 staining was absent in 8 of 8 tumors (100%) with mutation in exons other than exon 11. When immunohistochemical staining was performed with Ab-2 antibody, both nuclear and cytoplasmic staining were observed in 14 of 16 tumors (87.5%) with mutation in exon 11. Interestingly, nuclear staining was observed in 3 of 3 tumors (100%) with mutation downstream of exon 11, even though no staining was detected in 5 of 5 tumors (100%) with mutation upstream of exon 11. On the other hand, in familial ovarian cancers without BRCA1 mutations, nuclear staining or both nuclear and cytoplasmic staining was observed in 18 of 20 specimens (90%) and 20 of 20 specimens (100%) with GLK-2 antibody and with Ab-2 antibody, respectively. These results suggest that an immunohistochemical assay in combination with employing the C-terminal and the N-terminal antibodies appears to have potential as a reliable and useful technique for the screening of BRCA1 mutations, at least to predict the status of mutation, upstream or downstream of exon 11.

Abstract
Free cancer cells exfoliated from cancer-invaded serosa contribute to peritoneal dissemination, the most frequent pattern of recurrence in patients with gastric and ovarian cancers. This study was designed to evaluate the prognostic significance of free cancer cells in peritoneal washes detected using the reverse transcriptase-polymerase chain reaction (RT-PCR) and cytology. RT-PCR analysis with primers specific for the carcinoembryonic antigen (CEA) gene was found to be more sensitive than cytology for detection of free tumor cells in the peritoneal washes, collected at laparotomy from 199 gastric carcinoma patients, with higher detection rates for each of the T-categories in the TNM classification. Six patients with synchronous and 5 with recurrent peritoneal dissemination were found among 25 advanced cancer patients with positive PCR and negative cytology results. Positive PCR results were significantly associated with poor survival of curatively resected advanced gastric carcinoma patients (P < 0.001). A rapid method for detecting CEA mRNA using the LightCycler and the dsDNA binding dye SYBR green I was also developed. The results obtained using this technique were essentially the same as those obtained using the conventional RT-PCR method. Furthermore, RT-PCR analysis with primers specific for MUC1 epithelial mucin were performed on peritoneal washes from patients with ovarian cancer. Peritoneal washes from 21 of 25 ovarian carcinoma patients, including all 17 with positive cytology results, were positive for MUC1 mRNA, again indicating a higher sensitivity using this method than conventional cytology. Highly sensitive and rapid detection of free cancer cells in peritoneal washes, most reliably by RT-PCR, is a powerful technique to predict peritoneal dissemination in patients with gastric and ovarian cancers.

Abstract
OBJECTIVE The prognostic importance of adenocarcinoma of the uterine cervix was investigated. Methods. One hundred ninety-three patients (144 had stage I disease, 41 stage II, and 8 stage III-IV) with invasive adenocarcinoma of the uterine cervix treated initially at the Aichi Cancer Center between 1964 and 1995 were studied. RESULTS Of all the invasive cervical cancers, 8.8% were adenocarcinomas that had been increasing during the past decade. The overall 5-year survival for stage I was 88.8%, stage II 44.9%, and stage III-IV 0% In univariate analysis, the clinicopathological factors associated with overall survival and disease-free survival were age of patient, stage of disease, presence of nodal metastasis, number of lymph nodes involved, lymph-vascular space invasion, tumor size, and intraperitoneal metastasis. Multivariate analysis performed in all cases identified the clinical stage of disease, the presence of nodal metastasis, number of lymph nodes involved, lymph-vascular space invasion, and tumor size as the independent risk factors for recurrence and survival. In the analysis of stage I disease, lymph node metastasis and tumor size were the significant prognostic factors, while lymph-vascular space invasion and tumor size were the factors in advanced disease. Tumor grade and histological type were not associated with recurrence and survival. CONCLUSION These results suggested the association of lymph node metastasis with the prognosis of early stage adenocarcinoma of the uterine cervix and lymph-vascular space invasion with the advanced stage. Tumor size was an independent risk factor throughout all stages.

Abstract
To assess the impact of reproductive and anthropometric factors as a risk indicator for female cancers in hormone-related organs, i.e., the breast, endometrium and ovary, we conducted a comparative case-referent study using data from the Hospital-based Epidemiologic Research Program at Aichi Cancer Center (HERPACC), Japan. The case group consisted of 1,465, 133 and 99 women who had first been diagnosed as having breast, endometrial and ovarian cancer, respectively. The referents were 25,488 female first-visit outpatients who had not previously been diagnosed with any type of cancer. The odds ratios (ORs) and their 95% confidence intervals (95%CI) were estimated using an unconditional logistic regression model. An inverse association with experience of delivery and a positive association with body mass index (BMI) and with change of BMI after 20 years of age, were observed consistently for all three cancer sites. We observed similar risk and protective factors for breast and endometrial cancer, but the effect of reproduction and overweight condition (BMI> or =25) were more prominent in endometrial cancer. Although the present study failed to find site-specific risk factors for ovarian cancer, the results provided evidence that being overweight and/or weight gain in adult life is a common risk factor for all three cancer sites. The results obtained from this study suggested that avoidance of weight gain may reduce the risk of female hormone-related cancers.

Abstract
Thermolysin, a thermophilic metalloproteinase, is markedly activated in the presence of high concentrations (1-5 M) of neutral salts. The activity increases in an exponential fashion with increasing salt concentration, and is enhanced 13-15 times with 4 M NaCl at pH 7.0 and 25 degreesC (K. Inouye, Effects of salts on thermolysin: activation of hydrolysis and synthesis of N-carbobenzoxy-l-aspartyl-l-phenylalanine methyl ester, and a unique change in the absorption spectrum of thermolysin, J. Biochem. 112 (1992) 335-340). In this study, the effect of NaCl on the thermal stability of thermolysin has been examined at 60-85 degreesC. The activation energy, Ea, for the thermal inactivation is 15 kcal/mol at 0 M NaCl, and increases up to 30-33 kcal/mol by the addition of 0. 5-1.5 M NaCl. Further increase in [NaCl] decreases the Ea value, and at 4 M NaCl it is almost the same as that at 0 M NaCl. Thermolysin at 0.5-1.5 M NaCl is twice as heat-stable as in the absence of NaCl. The NaCl dependence of the stability is different from that of the activity, suggesting that the effects of NaCl on activity and stability are independent. Thermolysin has been demonstrated to be not only a thermophilic enzyme but also a highly halophilic one.

Abstract
BACKGROUND The prognoses of patients with squamous cell carcinoma of the ovary are quite poor. However, preoperative diagnosis is difficult due to the rarity of this tumor and its similarity to mature cystic teratoma (MCT). The objective of this study was to assess the value of tumor markers and clinical characteristics in making a differential diagnosis between MCT and squamous cell carcinoma arising from MCT. METHODS Between September 1979 and June 1996, 37 patients with ovarian squamous cell carcinoma arising from MCT were treated by the Tokai Ovarian Tumor Study Group. The authors evaluated tumor markers, tumor size, and age as parameters for differentiation between MCT and squamous cell carcinoma arising from MCT. Diagnostic efficiency was calculated as the sensitivity multiplied by the specificity. RESULTS There were significant differences (P < or = 0.0002) in age, tumor size, and levels of squamous cell carcinoma antigen (SCC), CA125, and CEA, as well as a significant difference (P < or = 0.0396) in the CA19-9 level between MCT and squamous cell carcinoma arising from MCT. Diagnostic efficiency was highest for SCC (63.0%), followed by CA125 (50.7%). Receiver operating characteristic (ROC) curves demonstrated that CEA was the best screening marker for squamous cell carcinoma arising from MCT, whereas age and tumor size were better markers than CA125 or CA19-9. The optimal cutoff values for age and tumor size were 45 years and 99 mm, respectively, according to ROC analysis. CONCLUSIONS These findings demonstrate that age and tumor size are important factors in making a differential diagnosis. In addition, SCC and CEA levels should be measured in patients age 45 years or older who have an MCT-like ovarian tumor larger than 99 mm in greatest dimension.

Abstract
Thermolysin is remarkably activated in the presence of high concentrations (1-5 M) of neutral salts [Inouye, K. (1992) J. Biochem. 112, 335-340]. The activity is enhanced 13-15 times with 4 M NaCl at pH 7.0 and 25 degrees C. In this study, the effect of neutral salts on the solubility of thermolysin has been examined. Although the solubility was only 1.0-1.2 mg/ml in 40 mM Tris-HCl buffer, pH 7.5, in the temperature range between 0 and 60 degrees C, it was increased greatly by the addition of salts. With NaCl, the solubility showed a bell-shaped behavior with increasing NaCl concentration, and the maximum solubility (10 mg/ml) was at 2.0-2.5 M NaCl. With LiCl and NaI, it increased progressively to 20-50 mg/ml with increasing salt concentration up to 5 M. The solubility observed in the presence of salts decreased with increasing temperature from 0 to 60 degrees C, and also with the order of chaotropic anion effect. The molecular weight of thermolysin was estimated to be 33.0(+/-2.5) x 10(3) in the presence of 0-3 M NaCl, suggesting that thermolysin exists as a monomer in the presence or absence of 3 M NaCl. The possibility that aggregation and/or dispersion of thermolysin might be related to the remarkable activation by salt was ruled out.

Abstract
The importance of the major risk and protective factors for cervical cancer in women by age group was evaluated with the use of data from the Hospital-based Epidemiologic Research Program at Aichi Cancer Center (HERPACC), Japan. This study included 416 cervical cancer cases and 20,985 referents confirmed as free of cancer. Cases and referents were divided into three age groups: the younger, middle and older age groups (30-44, 45-54 and 55-69 years old, respectively). Logistic model was applied separately to the three groups to estimate odds ratios (ORs) of smoking, beverage and dietary habits with adjustment for marital and reproductive factors. The elevated OR of current smokers was observed consistently in all age groups, while alcohol intake did not show any increased ORs. Dietary control for health lowered ORs for all three age groups, and the effect appeared to be more pronounced among the older age group (OR = 0.49, 95% confidence interval: 0.30-0.80). Higher frequency intake of green-yellow vegetables consistently afforded lower ORs among all three age groups. This risk increment of smoking and risk reduction by dietary control were consistent in all age groups. These findings suggested practicable prevention strategy for the cervical cancer by modifying general life style.

Abstract
After primary cytoreductive surgery, a randomized clinical trial was conducted in women with epithelial ovarian cancer to compare the impact on survival between PVB chemotherapy, consisting of cisplatin, vinblastine and bleomycin, and CAP chemotherapy, consisting of cyclophosphamide, aclacinomycin and cisplatin. There were 148 evaluable patients. One hundred and five patients with stage II, III and IV were analyzed in this study, 49 of them received PVB chemotherapy while the remaining 56 patients received CAP chemotherapy. Sixty-four patients fulfilled the criteria for clinical remission set by the Tokai Ovarian Tumor Study Group [Gynecol Oncol 1993;48:342-348]. The remission rate was 73 and 50% in the PVB and CAP groups, respectively, and showed a significant advantage for the PVB group (p = 0.0139). Moreover, the recurrence rate was 44% in the PVB group and 61% in the CAP group after clinical remission, although there was no significant difference between the two groups. The final survival rate was 32% in the PVB group and 24% in the CAP group. There was a significant difference of survival rate between both groups at 24 months (p = 0.0378) and 48 months (p = 0.0450), but finally no significant difference was found at 96 months (p = 0.0660). Compared to the CAP regimen, the PVB combination has a significantly higher efficacy in remission, but there was no significant difference in the long-term survival rate. Furthermore, multivariate analysis demonstrated that the PVB chemotherapy improved the survival, but it was not significant. The authors conclude that PVB chemotherapy may be more effective than CAP chemotherapy for epithelial ovarian cancer.

Abstract
BACKGROUND A newly synthesized drug, CKA1083 ((S)-N-[2-(4-benzyloxy-carbonylpiperazinyl)-1-(P-methoxybenzyl) ethyl]-N-methyl-N(5-isoquinolinesulfonamide)), has the same glutathione-S-transferase (GST)-binding site structure as W-77, a bifunctional inhibitor that enhances the cytotoxicity of Adriamycin for human ovarian carcinoma cells. We examined the effects of CKA1083 on the cytotoxicity of Adriamycin and the resistance of human ovarian carcinoma cells to this drug. MATERIALS AND METHODS We used GST-pi transfected cells and Adriamycin-sensitive or -resistant cells of human ovarian carcinoma. GST-pi activity, the intracellular Adriamycin content, and the cytotoxicity of Adriamycin in these cell lines in the presence or absence of CKA1083 were measured and compared to the findings obtained with W-77 or verapamil. RESULTS CKA1083 inhibited GST-pi activity in an uncompetitive manner and more strongly than W-77. It enhanced the cytotoxicity of Adriamycin for GST-pi transfected cells by about 3-times. Further, CKA1083 increased the intracellular Adriamycin content about 3-fold in two Adriamycin-resistant cell lines (NOS2AR and NOS3AR). CKA1083 (10 microM) reduced the IC50 of Adriamycin to 1/38 in NOS2AR cells and 1/21 in NOS3AR cells, and overcame Adriamycin resistance more effectively than both W-77 and verapamil. CONCLUSIONS CKA1083 enhanced the antitumor effect of Adriamycin more than W-77 by inhibiting both GST activity and P-glycoprotein.

Abstract
BACKGROUND We evaluated the clinical features, treatment, and survival status of the patients with borderline ovarian tumors. METHODS A retrospective review of the charts of 150 patients with borderline ovarian tumor registered at the Tokai Ovarian Tumor Study Group from January 1, 1980, to December 31, 1994, was conducted to obtain clinical and pathological information. RESULTS In stage II and III disease, the numbers of patients with no residual tumor, residual tumor of <2 cm, 2-5 cm, and >5 cm were 9, 10, 3, and 3, respectively. The sizes of residual tumors and corresponding clinical response to chemotherapy were as follows: residual tumor of <2 cm, complete response (CR), 6 patients; no change (NC), 2; progressive disease (PD), 2; tumors 2-5 cm, NC, 1 patient, PD, 2; tumors >5 cm, PD, 3 patients. The survival for patients with residual tumor <2 cm was significantly better than for those with residual tumor from 2-5 cm and of >5 cm (P < 0.05). The survival for patients with stage II and III serous tumor was significantly longer than that for patients with stage II and III mucinous tumor (P < 0.05). CONCLUSION In advanced borderline ovarian tumor, the prognosis of patients with gross residual tumor after initial surgery, and especially with mucinous tumor, was poor.

Abstract
In Japan the incidence of cervical cancer has been high, but has recently been decreasing gradually, while the incidence of endometrial cancer is running at lower levels but is gradually increasing. To clarify the common and/or specific risk and/or protective factors of cervical cancer(CC) in contrast with endometrial cancer (EC), a comparative case-control study was conducted at the Aichi Cancer Center Hospital, Japan. In total, 556 CC cases and 145 EC cases were included and 26,751 women, confirmed as free of cancer, were chosen as the common control group. Odds ratio and its 95% confidence interval (95%CI) for each exposure variable were estimated by using an unconditional logistic regression model adjusted for age and first-visit year. Habitual smoking and experience of pregnancy increased the risk of CC, while decreasing the risk of EC. Greater body mass index (>20), daily intake of fruit and more frequent intake of boiled or broiled fish (>1-2 times/week) decreased the risk of CC, whereas they increased the risk of EC. Daily intake of milk decreased the risk of CC. The results obtained from this study suggest that several EC-increasing risk factors are in fact CC-decreasing determinants. The observed risk reduction in both CC and EC by physical exercise and dietary control for health is noteworthy from the public health standpoint and warrants further investigation.

Abstract
Since the incidence of mucinous carcinoma of the ovary is relatively low, with only small numbers of cases at any institution, detailed clinicopathologic studies on the prognosis and the care of patients with mucinous carcinoma are missing. Forty-four patients with mucinous carcinoma were histopathologically subclassified into endocervical (n = 8) and intestinal types (n = 36), and studied for clinical manifestations. All tumors of the endocervical type were stage I, whereas 14 intestinal-type tumors were stage II or higher (p < 0.05). Stromal invasion was not observed in 14 of 44 tumors, 13 of which were stage I. Analysis of prognostic factors disclosed that the clinical stage, maximum residual tumor diameter, volume of ascites, stromal invasion, and preoperative CA125 and CA19-9 levels significantly affected prognosis. However, multivariate analysis (stepwise regression) showed that the only significant factor was clinical stage (p < 0.004). In conclusion it is believed that, pathologically, the endocervical-type mucinous carcinoma is not as aggressive as the intestinal-type cancer. The clinical stage was found to be a significant prognostic factor even by multivariate analysis, and the prognosis at stages III and IV was unfavorable compared to stages I and II.

Abstract
Mass screening for uterine cancer, mainly by cytological examination, has been conducted since 1962. The total number of examinees has been increasing and has remained at the same level for the last decade. The coverage rate of screening is only 16%, much lower than the target rate of screening, at present. According to the increase in the number of examinees, the mortality has fallen gradually, because the patients with cancer detected early on are increased and treated successfully with better QOL. However, there are some problems, as follows. 1) Although the coverage rate among the first-time examinee, women in their 30s and 70s are lower than the other groups, the rate of dysplasia and uterine cancer detected among them, are higher. 2) False, negative rate of cytology is relatively high. It is suggested the systemic mass screening is effective to reduce mortality from uterine cancer. It is necessary, however, to improve and certify the further efficacy of screening in reduction of mortality of uterine cancer, referring to procedures of cytology, especially for early detection of adenocarcinoma, and registration system from the point of cost-effectiveness.

Abstract
Between 1989 and 1991, 150 patients with ovarian cancer were treated with chemotherapy, including cisplatin, in the Tokai Ovarian Tumor Study Group. Of these patients, 25 underwent cytoreductive surgery with lymphadenectomy, including removal of either pelvic or para-aortic lymph nodes, and 36 underwent both lymphadenectomies. A significant difference was observed between survival curves of the groups with positive and negative lymph nodes, respectively (P = 0.0049). The overall survival was longer in the lymphadenectomy group than in the nonlymphadenectomy group (P = 0.0842), and a significantly longer survival time was noted for stage III patients who underwent lymphadenectomy compared with those who did not (P = 0.0185). Multivariate analysis demonstrated that lymphadenectomy is a positive prognostic factor. The authors conclude that both pelvic and para-aortic lymph nodes should be resected to improve survival as well as to assess exact staging in patients with ovarian cancer.

Abstract
BACKGROUND An association of human leukocyte antigen (HLA)-DQw3 alleles with squamous cell carcinoma (SCC) of the cervix has been reported in some European populations, but the significance of HLA-DQw3 has not been examined in other populations to the authors' knowledge. The interaction between HLA-DQw3 and human papillomavirus (HPV) in SCC remains to be clarified. METHODS To elucidate the association of HLA-DQ alleles with SCC of the cervix, DNA samples extracted from blood lymphocytes of 23 patients with SCC were amplified by the polymerase chain reaction (PCR) using specific primers for the DQB1 genes, and then, each HLA-DQB1 genotype was defined by digestion with restriction enzymes. Human papillomavirus typing also was performed in all cases by PCR, using specific primers for the E6 regions of cancer-associated HPV types (HPV 16, 18 and 33). RESULTS Twenty patients (87%) carried a DQB1 gene-encoding HLA-DQw3, compared with 49.4% Japanese control subjects in the International Histocompatibility Workshop panel (P = 0.0003). Human papillomavirus 16 or HPV 18 DNA was detected in 86% of the patients. In 13 of the patients with invasive carcinoma with HPV, a high incidence of not only HLA-DQw3 but also of HLA-DQw1 was observed compared with that in control subjects (P = 0.0019, P = 0.047, respectively). The correlation between DQB1*03 alleles and HPV infection was not statistically significant. CONCLUSION The frequency of HLA-DQw3 alleles was higher in the authors' patient group than in the control group, suggesting that the HLA-DQw3 molecules may influence the development of SCC of the cervix in young Japanese women. In the patients with HPV-positive invasive carcinoma, the association with HLA-DQw1 molecules suggested that it also may influence the progression of SCC.

Abstract
The activity of thermolysin is greatly enhanced in the presence of high concentrations of neutral salts [Holmquist, B. and Vallee, B.L. (1976) Biochemistry 15, 101-107; Inouye, K. (1992) J. Biochem. 112, 335-340]. NaBr and NaCl are the most effective for the activation. An absorption difference spectrum with a peak around 293 nm, which is characteristic of the red-shift of a tryptophyl residue caused by charge effects, was observed on mixing of thermolysin with NaCl. As the peak disappeared in the presence of competitive inhibitors of the enzyme (phosphoramidon and zincov), it was considered to be derived from a tryptophyl residue (Trp 115) located in the active site of the enzyme. On the other hand, this peak was not observed on the mixing of thermolysin and NaBr, indicating that the slight difference in size between chloride and bromide ions is critical for the interaction with the tryptophyl residue. NaCl and NaBr exhibit comparable effects on the activation of thermolysin regardless of the considerable discrepancy in their effects on the absorptivity difference around 293 nm. This suggests that the interaction of salts with Trp 115 is not necessarily correlated with the activation of thermolysin.

Abstract
After primary cytoreductive surgery 188 patients with epithelial ovarian cancer were treated with combination chemotherapy between 1986 and 1989 in the Tokai Ovarian Tumor Study Group. Clinical remission criteria were set in this study and patients were examined to determine if they were in remission or not. Forty-seven cases (25%) had no remission and 85.9% of them died within 20 months after primary surgery. Fifty-seven cases (30.3%) had a remission and a subsequent recurrence. Eighty-four cases (44.7%) had no recurrence and all are currently alive. Independent remission factors by multivariate analysis were higher stage (P = 0.018), clear-cell carcinoma (P = 0.0048), larger maximum residual tumor (P = 0.0023), and PVB therapy (P = 0.026). Independent recurrence factors were higher stage (P = 0.0012), serous cystadenocarcinoma (P = 0.0001), clear-cell carcinoma (P = 0.00409), and PVB therapy (P = 0.0499). A significantly high remission rate and low recurrence rate was achieved using PVB therapy. This criteria has value for the treatment of epithelial ovarian carcinoma. The disease-free survival rate after clinical remission was the same as that after a negative second-look laparotomy, which implies that a second-look laparotomy may be unnecessary in the management of epithelial carcinoma of the ovary.

Abstract
OK-432, a streptococcal preparation, was administered to patients with stage Ib and II cervical carcinoma except for adeno- and adenosquamous carcinomas. To evaluate the efficacy of OK-432 precisely, 177 patients were stratified by clinical stage, radiotherapy, and lymph node metastasis after complete radical hysterectomy and pelvic lymphadenectomy. Within each stratum, patients were divided randomly into OK-432 and control groups. 85 patients received OK-432 and 92 patients did not. No significant difference was observed in overall 5-year disease free rates between the OK-432 and the control groups, although the mean diameter of erythema on SU-polysaccharide (SU-PS) skin test was larger in the OK-432 group than in the control group. In stage IIb, a significant difference was observed between the OK-432 and control groups. This difference, however, could be attributed in part to the different incidence of the lymph node metastasis. In stage II without lymph node metastasis, 5-year disease free rate was significantly higher in the OK-432 group.

Abstract
Seven tumor markers were analyzed clinically in 135 patients with germ cell tumors of the ovary who were treated in Tokai Ovarian Tumor Study Group, an association comprising Nagoya University and its affiliated hospitals, between January 1979 and September 1990. Positive rate of AFP was 100% (36/36) in yolk sac tumor, 61.9% (13/21) in immature teratoma, and 11.8% (2/17) in dysgerminoma, but there were no positive cases of mature cystic teratoma with malignant transformation (0/7) and mature cystic teratoma (0/31). Positive rate of CA125 was over 50% in all tumor types except mature cystic teratoma, which showed a positive rate of 23.7%. CA125 was useful for the screening of malignant germ cell tumors. CA19-9 showed a high positive rate in teratomatous tumors, which were immature teratoma, mature cystic teratoma with malignant transformation, and mature cystic teratoma. Dysgerminoma and yolk sac tumor, especially dysgerminoma, had a high positive rate of LDH. TPA and CEA were not considered useful tumor markers for germ cell tumors of the ovary.

Abstract
The purpose of this study was to establish the optimal management of immature teratoma of the ovary. Pursuant to this, 20 previously untreated patients with immature teratoma were evaluated. Nine patients were at stage I of the disease, 2 had progressed to stage II, and 9 to stage III. Eight patients had grade 1 tumors, 11 had grade 2 tumors, and 1 had a grade 3 tumor. Postoperative chemotherapy was performed in 19 cases. Vincristine, actinomycin D, and cyclophosphamide (VAC) were administered in 9 cases, chemotherapy including cisplatin (P) was administered in 8 cases, and other regimens were followed in the 2 remaining cases. The median follow-up period was 62 months (range 19-108 months), and no patient was lost to follow-up. After completion of the follow-up period, 18 patients were alive and disease free, 1 was alive with liver metastasis, and 1 had died. The patient who died had suffered from a grade 3 tumor, and the recurrent tumor was a rhabdomyosarcoma. As a result of this study, it was found that immature teratoma of grades 1 and 2 can be managed successfully with VAC or P therapy. Thus, a hysterectomy should not be automatically performed in patients who still hope to give birth, yet suffer from a grade 1 or 2 immature teratoma at the time of a second operation.
