[PMID: 35923700 PMCID: PMC9340375 DOI: 10.3389/fgene.2022.917481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 06/27/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Ubiquitin specific protease 1 (USP1) tightly correlates with poor prognosis of multiple cancers. However, whether USP1 underlies ovarian cancer (OV) progression remains unclarified.Methods: First, GSEA strategy and WGCNA analysis were used to screen for anti-ovarian cancer drugs and furthern optimal module, respectively. In addition, functional enrichments of module genes were realized by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Kaplan-Meier was then employed to analyze the prognostic impact of USP1 expression on OV patients. Cell proliferation and cell cycle assays were used to confirm biological functions of USP1 in the final.Results: Through the forementioned methods, we obtained five candidate drugs against OV from 353 anticancer drugs, and proposed ML323 as a novel anti-OV drug. As our hypothesized, ML323 significantly inhibited the proliferation of OV cells. Combined with WGCNA and KEGG analysis, the turquoise module was related to ML323, together with cell cycle. USP1 was subsequently identified as a target of ML323 and according to the TCGA database, USP1 negatively correlated with prognosis in OV, and its reduction and ML323-treatment both inhibited the proliferation of OV cells, blocking the S phase of cell cycle in vitro.Conclusion: Taken together, ML323 exerts its inhibitory effect on the proliferation of OV cells by targeting USP1-regulated cell cycle, providing a therapeutical strategy and potential target against OV.

Survival of Advanced Stage High-Grade Serous Ovarian Cancer Patients in the Republic of Macedonia. Open Access Maced J Med Sci 2017; 5:904-908. [PMID: 29362616 PMCID: PMC5771292 DOI: 10.3889/oamjms.2017.215] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2017] [Revised: 10/12/2017] [Accepted: 10/28/2017] [Indexed: 11/25/2022] Open
Abstract
AIM: The primary objective of the study was to evaluate the overall survival of women with advanced stage (Stage IIIA-IV) high-grade serous ovarian cancer in Macedonia MATERIALS AND METHODS: The study was a cross-sectional medical record review of patients diagnosed with advanced stage HGSC. Patients were deemed eligible for inclusion if they were diagnosed with an advanced stage (Stage IIIA-IV) HGSC of the ovary, fallopian tube or peritoneum between 2009 and 2015. The data were analyzed in a descriptive fashion and summary statistics were provided, as appropriate. Survival was calculated using the Kaplan-Meier method. RESULTS: A total of 81 eligible patients were identified and included in the study. The average overall survival in the studied cohort was 46.59 months (95%CI = 39.11-54.06). Patients that were optimally debulked and patients that had a platinum-free interval larger than 12 months had significantly longer survival in the current series (p < 0.001). CONCLUSION: the average overall survival of advanced stage HGSC patients in the studied series was 46.59 months (95%CI = 39.11-54.06). Patients aged 65 years or younger tended to live approximately ten months longer than patients older than 65 years, but this difference was not statistically significant. There was no difference in HGSC survival in the groups of patients with grade 2 and grade 3 disease. However, optimal surgical debulking and platinum sensitivity were associated with significantly better overall survival.

Abstract
Platinum-based chemotherapy has led to an improvement in complete response rates and duration of median remission, but has only given a modest improvement in overall survival in patients with advanced ovarian cancer. Chemotherapy will in the future focus upon: (1) improving the complete remission rate with new induction regimens; (2) identifying strategies capable of converting partial remission into complete remission; (3) preventing or delaying recurrences in patients who do achieve a complete remission; (4) identifying mechanisms of antineoplastic drug resistance and pharmacologic techniques capable of reversing drug resistance. Among the treatment approaches being utilized are high-dose chemotherapy with autologous bone marrow transplantation, development of new chemotherapeutic regimens which include Taxol and hexamethylmelamine, and intraperitoneal chemotherapy. In addition, our understanding of the mechanisms of antineoplastic drug resistance has led to the development of novel therapeutic approaches. It has been demonstrated that resistance to platinum and alkylating agents is associated with both increased concentrations of cellular glutathione (GSH) as well as an increased capacity of tumor cells to repair damage to DNA. Inhibition of GSH biosynthesis with buthionine sulfoximine (BSO), a synthetic inhibitor of the enzyme gamma glutamyl cysteine synthetase, has led to the potentiation of alkylating agent activity in vitro and in vivo. A phase I trial of BSO plus melphalan is currently in progress and a trial of BSO plus carboplatin is planned. Inhibition of the DNA repair process with aphidicolin potentiates the cytotoxicity of cisplatin in drug-resistant tumor cells. Clinical trials of aphidicolin plus cisplatin await the completion of ongoing phase I trials of aphidicolin.

Abstract
Ovarian cancer remains the most common cause of gynecologic cancer-related death among women in developed countries. Nevertheless, subgroups of ovarian cancer patients experience relatively longer survival. Efforts to identify prognostic factors that characterize such patients are ongoing, with investigational areas including tumor characteristics, surgical management, inheritance patterns, immunologic factors, and genomic patterns. This review discusses various demographic, clinical, and molecular factors implicating longevity and ovarian cancer survival. Continued efforts at identifying these prognosticators may result in invaluable adjuncts to the treatment of ovarian cancer, with the ultimate goal of advancing patient care.

Abstract
Uptake of the anticancer drug cisplatin is mediated by the copper transporter CTR1 in cultured cells. Here we show in human ovarian tumors that low levels of Ctr1 mRNA are associated with poor clinical response to platinum-based therapy. Using a mouse model of human cervical cancer, we demonstrate that combined treatment with a copper chelator and cisplatin increases cisplatin-DNA adduct levels in cancerous but not in normal tissues, impairs angiogenesis, and improves therapeutic efficacy. The copper chelator also enhances the killing of cultured human cervical and ovarian cancer cells with cisplatin. Our results identify the copper transporter as a therapeutic target, which can be manipulated with copper chelating drugs to selectively enhance the benefits of platinum-containing chemotherapeutic agents.

Abstract
Studies on cytoreductive surgery for advanced ovarian and primary peritoneal cancer have consistently shown a strong correlation between cytoreduction and survival, with the best survival observed in patients who have no visible residual disease after successful cytoreductive surgery. Recent data that intraperitoneal chemotherapy further improves survival after optimal cytoreduction adds to the potential benefit of such surgery. More recently, significant survival benefit from optimal cytoreduction has also been shown for patients with recurrent disease and for women with advanced endometrial carcinoma. The selection criteria for patients and critical aspects of the operative technique and timing of cytoreductive surgery are discussed.

Abstract
Surgery plays a critical role in the optimal management of all stages of ovarian carcinoma. In apparent early-stage ovarian cancer, a comprehensive surgical evaluation allows stratification of patients into low- and high-risk categories. Low-risk patients may be candidates for fertility-sparing surgery and can safely avoid chemotherapy and be observed. Treatment of patients with high-risk early- or advanced-stage ovarian cancer usually requires a combined modality approach. Although it is well known that epithelial ovarian cancer is moderately chemosensitive, what distinguishes it most from other metastatic solid tumors is that surgical cytoreduction of tumor volume is highly correlated with prolongation of patient survival. Procedures such as radical pelvic surgery, bowel resection, and aggressive upper abdominal surgery are commonly required to achieve optimal cytoreduction. Women who develop recurrent disease may be eligible for a secondary cytoreductive surgery or may require a surgical intervention to palliate disease-related symptoms. For women at high risk of ovarian cancer, prophylactic bilateral salpingo-oophorectomy significantly reduces the incidence of this disease. The purpose of this article is to provide a comprehensive review of the surgical management of ovarian carcinoma. The roles of primary, interval, and secondary cytoreductive surgeries; second-look procedures; and palliative surgery are reviewed. The indications for fertility-sparing and minimally invasive surgery as well as the current guidelines for prophylactic surgery in high-risk mutation carriers are also discussed.

Abstract
OBJECTIVE Oxaliplatin and topotecan have demonstrated activity as single agents against recurrent platinum-sensitive and -resistant ovarian cancer, as well as synergy in vitro. This was a dose-finding study of combination therapy with weekly topotecan and alternating-week oxaliplatin in patients with recurrent epithelial ovarian cancer. METHODS Eligible patients had a diagnosis of recurrent ovarian or primary peritoneal carcinoma, a performance status of 0-2, and normal bone marrow, renal, and hepatic function. On days 1 and 15 of a 28-day cycle, patients received a fixed dose of oxaliplatin (85 mg/m2) via intravenous infusion. On days 1, 8, and 15, patients received an escalating dose of intravenous topotecan (2.0-4.0 mg/m2). Five dose levels were planned with a minimum cohort of 3 patients at each level. RESULTS Thirteen patients were enrolled and received a total of 50 cycles of chemotherapy. The maximum tolerated dose was 85 mg/m2 of oxaliplatin and 3.0 mg/m2 of topotecan, and grade 3 neutropenia was the dose-limiting toxicity. Four of nine (44%) evaluable patients had stable disease or a partial response to the drug combination as assessed by cancer antigen-125 levels. CONCLUSIONS A 28-day schedule of oxaliplatin and topotecan is safe and well tolerated. Because of the in vitro synergy observed between topoisomerase I inhibitors and platinum derivatives and the tolerability reported in the current study, this regimen warrants further investigation.

Abstract
Epithelial ovarian cancer is the leading cause of death from gynecological cancer in the Western countries. Approximately 20%–30% of patients with early-stage disease and 50%–75% of those with advanced disease who obtain a complete response following first-line chemotherapy will ultimately develop recurrent disease, which more frequently involves the pelvis and abdomen. Few formal guidelines exist regarding the surveillance of these patients, and there is no agreement in the literature about the type and timing of examinations to perform. Moreover, the objective of follow-up is unclear as recurrent epithelial ovarian cancer continues to be a therapeutic dilemma and quite all the relapsed patients will eventually die of their disease. The follow-up of asymptomatic patients generally include complete clinical history, serum cancer antigen (CA)125 assay, physical examination, and often ultrasound examination, whereas additional radiologic imaging techniques are usually performed when symptoms or signs appear.18Fluoro-2-deoxy-glucose (18FDG)–positron emission tomography (PET) has a sensitivity of 90% and a specificity of 85% approximately for the detection of recurrent disease, and this examination appears to be particularly useful for the diagnosis of recurrence when CA125 levels are rising and conventional imaging is inconclusive or negative. Recently, technologic advances have led to novel combined18FDG-PET/computed tomography (CT) devices, which perform contemporaneous acquisition of both18FDG-PET and CT images. The role of18FDG-PET/CT for the detection of recurrent ovarian cancer is very promising, and this technique may be especially useful for the selection of patients with late recurrent disease who may benefit from secondary cytoreductive surgery.

Abstract
Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States. Although there has been a statistically significant improvement in 5-year survival, in 2005 more than 16,000 women were expected to die of this disease. To date, there is no reliable method to screen for ovarian cancer; therefore, the majority of cases are diagnosed with advanced disease. For early ovarian cancer, appropriate surgical staging and adjuvant chemotherapy for selected cases will result in survival rates of 90-95%. For advanced ovarian cancer, survival depends primarily on the success of the initial surgical procedure. Patients with complete cytoreduction to microscopic disease are often cured with adjuvant chemotherapy. There is growing evidence that these patients with microscopic residual disease are excellent candidates for intraperitoneal chemotherapy, and this mode of chemotherapy delivery may be their best opportunity for cure. Patients with optimal cytoreduction also may benefit from intraperitoneal chemotherapy, but cure is less likely. For patients with suboptimal cytoreduction, intravenous chemotherapy with a combination of carboplatin and paclitaxel is the current standard therapy. Most of these patients will experience recurrence of the cancer, with small chance of cure. Salvage chemotherapy is important in ovarian cancer because many patients respond to several salvage regimens. Because of the high response rate of ovarian cancer, even after relapse, it is probably better to consider 10-year survival as the ideal end point. Finally, new biologic agents, in combination with traditional surgery and chemotherapy, may result in further improvement in survival for patients with ovarian cancer.

Abstract
OBJECTIVE This study examined MASPIN expression in human ovarian cancer, and explored the association between MASPIN and prognosis in patients with advanced stage disease treated with first-line cisplatin, carboplatin and/or paclitaxel. METHODS Frozen primary tumors were obtained from 68 women with previously untreated, advanced stage epithelial ovarian cancer who participated in a specimen banking protocol and a phase III treatment trial conducted by the Gynecologic Oncology Group. Immunoblot analysis was performed in lysates prepared from these tumor specimens to quantify the relative expression of MASPIN/beta-actin. RESULTS MASPIN was expressed at detected levels in 49 (72%) cases with relative expression ranging from 0.02 to 7.7 (median = 0.2), and was not detected in 19 (28%) of the primary tumors tested. Non-detectable levels of this class II tumor suppressor gene product and inhibitor of angiogenesis were associated with suboptimally-debulked disease (P = 0.034) but not with patient age, FIGO stage, tumor grade, or histologic subtype. After adjusting for prognostic variables for disease progression or death, non-detectable MASPIN expression predicted an increased risk of disease progression (hazard ratio [HR] = 1.89; 95% confidence interval [CI]: 1.04-3.45; P = 0.038) and death (HR = 1.99; 95% CI: 1.07-3.69; P = 0.030). CONCLUSIONS In advanced stage epithelial ovarian cancer, non-detectable MASPIN appears to be associated with suboptimally-debulked disease and be an independent predictor of an increased risk of progression and death. Further studies are needed to validate these exploratory findings, determine the molecular mechanism controlling MASPIN expression as well as down-regulation and loss in ovarian cancer, and determine if MASPIN can prevent progression of this disease.

Abstract
The value of secondary cytoreductive surgery (SCS) for recurrent ovarian cancer is still controversial. The aim of this study was to clarify candidates for SCS. Between January 1987 and September 2000, we performed SCS in 44 patients with recurrent ovarian cancer, according to our selection criteria, disease-free interval (DFI) >6 months, performance status <3, no apparent multiple diseases, age <75years and no progressive disease during preoperative chemotherapy, if undertaken. The variables were investigated by univariate and multivariate analyses. Of 44 patients, 26 (59.1%) achieved complete removal of all visible tumours at SCS. Secondary cytoreductive surgery outcome, complete or incomplete resection, was significantly related to overall survival (P=0.0019). As for variables determined before SCS, DFI >12 months, no liver metastasis, solitary tumour and tumour size <6 cm were independently associated with favourable overall survival after recurrence in the multivariate analysis. Patients with three or all four variables (n=31) had significantly better survival compared with the other patients (n=13) (47 vs 20 months in median survival, P<0.0001). In these patients, fairly good median survival (40 months) was obtained even in patients with incomplete resection. Secondary cytoreductive surgery had a large impact on survival of patients with recurrent ovarian cancer when they had three or all of the above-mentioned four factors at recurrence. These patients should be considered as ideal candidates for SCS.

Abstract
Despite advances in surgical modalities and chemotherapeutic agents, the 5-year survival for patients with advanced ovarian cancer is barely 40-50%. At the moment, optimally cytoreductive primary surgery is the best option for patients with advanced ovarian cancer. Predictive factors of primary optimum reduction surgery have been described based on imaging studies and tumor markers and based on the premise to know a priori the weight and tumor volume, with promising results. A retrospective study was conducted based on the hypothesis that it is feasible to identify those patients not susceptible of undergoing optimum primary cytoreductive surgery. The variables associated with a lesser probability of success in this study are the presence of palpable abdominal tumor on physical examination, the presence of tumor in Douglas' cul-de-sac on vaginal exploration, the presence of ascites in any quantity, elevation of CA-125 above 1000 U/l, and the presence of pulmonary and liver metastases. The success rate for cytoreduction was 62% when none or one of these variables was present and 32% when two or more variables were present.

STUDY DESIGN RNA from 44 advanced serous ovarian cancers (19 optimal, 25 suboptimal) was evaluated with microarrays that contain >22,000 genes. Genes were screened on the basis of their association with debulking status to obtain the top 120 differentially expressed genes. These genes were then used to develop a predictive model for debulking status, which was subjected to out-of-sample cross validation. RESULTS We found that patterns of expression of 32 genes can distinguish between optimal and suboptimal debulking with 72.7% predictive accuracy. An analysis of the data that were based on clusters of co-ordinately expressed genes resulted in only a marginal improvement in predictive accuracy (75%). CONCLUSION These data support the hypothesis that favorable survival that is associated with optimal debulking of advanced ovarian cancers is due to, at least in part, the underlying biologic characteristics of these cancers.

Abstract
We report an observational study of chemotherapeutic regression of ovarian tumor implants according to decrements in residual mass size after surgical cytoreduction. Cytoreductive operations were attempted on 74 consecutive patients with stages IIIB-IV disease referred for this purpose. Thirty-two patients had received one to four courses of preoperative chemotherapy (22 responses, no progressions). Postoperative chemotherapy followed current protocols at Dana Farber Cancer Institute (n=61) or referring institutions (n=13); 57 regimens contained cisplatin. Postchemotherapy response was assessed clinically or by second-look procedures. Negative findings were considered a complete remission. Masses > 1 cm were excised from 62 patients. Twelve patients were inoperable. Twenty-eight patients had complete remissions and the correlation between these and decrements in residual mass size was highly significant (P < 0.0001). Complete remissions had a uniform effect and were the only outcome predictive of survival. Preoperative treatment greatly facilitated cytoreduction but only masses 0-0.2 cm were sensitive to postoperative chemotherapy. Masses 0.5 cm or less were optimal. They made up 77% of operable patients and supplied 25 (89%) of the complete remissions. Cytoreduction is not always required but even large-volume disease in the upper abdomen can be safely excised. The concept that masses larger than 10 cm indicate general chemoresistance has not been sustained.

Abstract
OBJECTIVE The purpose of this study was to determine the efficacy, tolerability, and pharmacokinetics of intraperitoneal (ip) paclitaxel combined with intravenous (iv) carboplatin and cyclophosphamide. PATIENTS AND METHODS Twenty-five newly diagnosed patients with Stage IC-IV epithelial ovarian cancer received ip paclitaxel with iv carboplatin and cyclophosphamide as a first-line treatment. Paclitaxel pharmacokinetics was determined during the first cycle on day 1 or 8. RESULTS This regimen was well tolerated, as abdominal pain and hematological toxicities were minor, while neurotoxicity grade I/II was reported in only 20% and myalgia in 24% of patients and were fully reversible. After treatment 13 of 18 (72%) of the patients had no evidence of disease. At a median follow-up of 30 months patients with residual disease after surgery (n = 10) had a median progression-free survival (PSF) of 13 months; for the optimally debulked group (n = 15) the actuarial PFS was 60% at 48 months. The elimination of paclitaxel from the peritoneal cavity and plasma followed first-order kinetics and was not influenced by adding carboplatin with cyclophosphamide. CONCLUSION This regimen was well tolerated, with minimal hematologic or neurotoxicity, and allowed the application of a triple-drug schedule without compromising dose intensity. To judge its efficacy, comparison with a standard iv paclitaxel-based schedule should be performed in a formal phase III study.

Abstract
The majority of women with ovarian cancer will present at an advanced stage and ultimately experience a recrudescence of tumor. Recent data indicates that secondary cytoreductive surgery is feasible, well tolerated and associated with significant prolongation of survival in selected patients with recurrent ovarian cancer.

Abstract
D-Methionine has recently been advocated as a protectant against cisplatin toxicity. The use of systemic D-methionine as a protector was studied in 58 guinea pigs. Kinetics and distribution of [11CH(3)]D-methionine was analysed by positron emission tomography. Cisplatin and the monohydrated complex of cisplatin was quantified in blood ultrafiltrate using reversed-phase liquid chromatography with post-column derivatisation. Administration of 300 mg/kg of D-methionine caused a 30% decrease in the area under the concentration-time curve (AUC) of cisplatin. The toxic effect of cisplatin was studied after dose adjustment of cisplatin, i.e. with similar cisplatin AUC in the group receiving D-methionine and the saline control group. A significant ototoxic effect, measured as difference in pre- and 96 h post-treatment electrophysiological hearing threshold (auditory brainstem response), was observed at stimulus frequencies of 30 and 20 kHz. There was no difference between the groups in the extent of threshold shift. Quantitative outer hair cell counts showed a similar loss of cells in the two groups. All animals had a significant increase in plasma-creatinine but there was no difference between the groups. The results indicate that protection from cisplatin ototoxicity by systemic D-methionine can be explained by a lowered systemic exposure to the drug.

Abstract
OBJECTIVES To determine the fraction of patients diagnosed with ovarian cancer and seen by a gynecologic oncologist and to compare outcomes with those patients and others who are not seen by a gynecologic oncologist. METHODS The statewide, population-based Utah Cancer Registry was used to identify 848 patients diagnosed with epithelial ovarian cancer between 1992 and 1998. Differences between selected characteristics of cases seen/not seen by gynecologic oncologists were assessed with chi2 tests, and survival data were analyzed using Kaplan-Meier curves and log-rank testing. RESULTS Of 848 incident epithelial ovarian cancer cases diagnosed in Utah residents during the period 1992-1998, 333 (39.3%) were seen by a gynecologic oncologist at some time during their cancer diagnosis and/or treatment. The percentage of ovarian cancer cases seen by a gynecologic oncologist varied with age: 35.6% of cases under 40 years of age at diagnosis were seen by a gynecologic oncologist, as were 54.5% of cases 40-59 years of age, 42.6% of cases 60-69 years, and 23.7% of women 70+ years of age (chi2 test, P < 0.01). The percentage of ovarian cancer cases seen by a gynecologic oncologists increased during the study period, from 33.0% in 1992-1993 to 47.5% in 1997-1998 (chi2 test for trend, P < 0.01). The vast majority of the state's population resides within a contiguous, four-county area near the only major city where gynecologic oncology care is available. Ovarian cancer cases that resided within that geographic area were generally more likely to have been seen by a gynecologic oncologist than those who lived in more rural regions of the state (42.7 and 27.1%, respectively; chi2 test, P < 0.01). For ovarian cancer cases diagnosed with local or regional stages of disease, there were no significant differences in survivorship between those treated or not treated by gynecologic oncologists. Among cases diagnosed with advanced disease, those cases seen by gynecologic oncologists had a significant survival advantage when compared to those that were not (median survival 26 and 15 months, respectively, P < 0.01). CONCLUSIONS Gynecologic oncologists see less than half of ovarian cancer patients. Patients under 40 years of age, over 70 years of age, and in rural areas were significantly less likely to be seen by a gynecologic oncologist in their course of treatment. Patients with advanced disease experienced a significant survival advantage when a gynecologic oncologist was involved in their care.

Abstract
OBJECTIVE The aim of this study was to evaluate the 2-year survival rate in a group of women in complete clinical remission (cCR) from Stage III ovarian cancer following front-line therapy who were then treated with a 6-month course of altretamine. METHODS Patients were documented to be in cCR by physical examination, computed tomography or magnetic resonance imaging scan, and serum CA-125. Treatment consisted of altretamine (Hexalen) 260 mg/m(2)/day po divided into four doses taken after meals and at bedtime for 14 of 28 days for six cycles. Based on previous experience in the Southwest Oncology Group, the treatment would be considered promising if the 2-year survival rate was > or = 65% as measured from study registration. RESULTS From 9/1/93 and 7/1/97, 112 patients were registered and 97 were fully evaluable. The majority of patients had optimally debulked (< or = 1 cm: 63%), high-grade (Grade 3: 82%) tumors. The 2-year survival rate in this study was 75% (95% CI: 66-84%). For those patients with optimal disease, the 2-year survival rate was 82% (95% CI: 72-92%) and for those with suboptimal disease it was 64% (95% CI: 48-79%). Four patients (4%) experienced Grade 4 and 21 patients (22%) experienced Grade 3 toxicities consisting primarily of nausea/vomiting, neutropenia, fatigue, anxiety, and paresthesias. CONCLUSIONS The 2-year survival rate in this study warrants further evaluation of consolidation therapy for women in clinical complete remission following front-line chemotherapy for Stage III ovarian cancer. Caution is advised in the interpretation of these data, however, because of the nonrandomized nature of the trial and the unknown contribution of front-line use of paclitaxel to the durability of clinical complete response.

Abstract
We report our experience with consolidative 32P after second-look laparotomy. Forty-three patients received consolidative 32P after platinum-based chemotherapy and a negative (39 patients, 91%) or positive (4 patients) second-look laparotomy. Thirty-one patients (72%) initially had stage III (30 patients) or stage IV (1 patient) disease; 28 patients (65%) had grade 3 tumors. Patients had follow-up from 3.5 to 14.9 years (median, 7.7 years); no patient was lost to follow-up. The 5-year rates of control of disease within the abdomen (local control) for the overall group and the subset of patients with stage II-IV disease and a negative second-look laparotomy were 65% and 69%, respectively. The corresponding 5-year survival rates were 78 and 81%, respectively. Multivariate analyses revealed that tumor found at second-look laparotomy significantly influenced the likelihood of local control and cause-specific survival. Acute side effects included cellulitis (1 patient) and ileus (3 patients). Two patients (5%) experienced severe late complications; both experienced small bowel obstruction that necessitated surgical intervention. Consolidative 32P appears to reduce the risk of recurrence and improve survival after negative second-look laparotomy. The risk of significant complications is low.

Abstract
PURPOSE Despite the improved results in advanced ovarian cancer achieved with the addition of paclitaxel to frontline therapy, there remains room for improvement. One approach is to add new agents such as topotecan. Because myelosuppression limits the delivery of topotecan with paclitaxel/cisplatin in a three-drug combination, we explored giving sequential couplets of cisplatin/topotecan followed by paclitaxel/cisplatin. PATIENTS AND METHODS Forty-four patients with residual epithelial ovarian carcinoma after primary surgery were studied. Cisplatin 50 mg/m(2) on day 1 and topotecan 0.75 mg/m(2) on days 1 through 5 were administered at 21-day intervals for four cycles, followed by interval debulking surgery (if optimal debulking was not achieved with primary surgery), and then paclitaxel 135 mg/m(2) over 24 hours on day 1 and cisplatin 75 mg/m(2) on day 2 at 21-day intervals for four cycles. RESULTS Such sequential couplets are feasible. Myelotoxicity was the major toxic effect, but it was of short duration. The granulocyte nadir with topotecan/cisplatin occurred late (median, day 18), so retreatment on day 21 was not always possible. There was no unexpected nonhematologic toxicity. The regimen was active in this group of patients who had undergone largely suboptimal debulking surgery. In 34 patients with clinically measurable disease, the overall response rate was 78%, and 30 (77%) of the 39 patients with elevated CA 125 levels at baseline had normalization of CA 125 levels by the end of therapy. CONCLUSION Sequential couplets of cisplatin/topotecan followed by paclitaxel/cisplatin are feasible. The efficacy data in this suboptimal group of patients has encouraged us to proceed with a randomized study based on this approach.

Abstract
OBJECTIVE The aim of this study was to assess the clinical benefit of salvage surgical cytoreduction in patients with late recurrent ovarian cancer. METHODS Thirty patients with recurrent ovarian cancer who underwent salvage surgical cytoreduction were retrospectively reviewed. All had been initially treated by primary surgery and platinum-based chemotherapy and had a period of clinical remission of at least 6 months. Median time to recurrence was 17.5 months (range, 6-76 months). RESULTS A macroscopically complete salvage cytoreduction was obtained in 17 (56.7%) patients, whereas 8 patients were left with macroscopic residual disease <2 cm and 5 patients with a larger residuum. Logistic regression showed that the probability of achieving a complete cytoreduction was significantly related to the residual disease after initial surgery (<2 cm versus >2 cm, P = 0.0027, odds ratio = 36.000, 95% confidence interval = 3. 473-373.176), but not to FIGO stage, tumor grade, histologic type, patient age at recurrence, and time to recurrence. In the whole series median survival following salvage surgery was 21 months. Survival was significantly longer in patients who were completely cytoreduced compared to those who were not (median: 37 months versus 19 months, P = 0.04). Moreover, survival was significantly related to time to recurrence (>17.5 months versus <17.5 months, median: 25 months versus 15 months, P = 0.039), number of recurrence sites (single versus multiple, median: 40 months versus 19 months, P = 0. 009), and residual disease after initial surgery (<2 cm versus >2 cm, median: 37 months versus 19 months, P = 0.01), but not to patient age, recurrence site with the largest size, FIGO stage, tumor grade, and histologic type. CONCLUSIONS The present data seem to show that complete salvage surgical cytoreduction significantly improves further survival of ovarian cancer patients who recur at least 6 months after the completion of primary therapy.

Abstract
Due in most part to the abundant retrospective evidence suggesting that surgical cytoreduction is essential to the management of advanced ovarian cancer, most clinicians do not question its application. Irrespective, there are many who still doubt its value, given its unique role in ovarian cancer, in comparison to other solid tumors. While many papers have extolled the virtues of debulking surgery, few have taken the opposing view. This paper attempts to expose the weaknesses in the current available data regarding surgical cytoreduction in advanced ovarian cancer. By reviewing the retrospective data, the theoretical benefits of surgery, cellular kinetics, the fallacies of residual disease, interval debulking surgery, and neoadjuvant chemotherapy, a critique of debulking surgery is made. Issues surrounding perioperative morbidity and its impact on quality of life have not been adequately addressed. Despite the need for randomized trials of surgery in advanced ovarian cancer, they are unlikely to occur. The window of opportunity with respect to studying the questions on the optimal timing, degree of aggressiveness, and patient selection for surgery has likely passed. Biases and ethical issues based upon the data cited in this paper have and will continue to hamper our ability to fully elaborate the benefits of surgery with respect to survival and quality of life.

Abstract
Cisplatin (8 mg/kg) was given intravenously to guinea pigs either as a 15 s bolus injection (25 animals) or as a 1 h infusion (28 animals). To determine the influence of the mode of cisplatin administration and pharmacokinetics on the ototoxic side-effect, the concentrations of cisplatin and the biotransformation product monoaquated cisplatin were determined in blood ultrafiltrate using liquid chromatography with post-column derivatization. Ototoxic effect was evaluated as difference in pre- and 96 h post-exposure auditory brainstem response (ABR) threshold. The cisplatin peak concentration was considerably higher, 19.2+/-2.4 microg/ml, in the bolus injection group than in the infusion group, 6.7+/-0.5 microg/ml (mean+/-S.E.M.). The area under the blood ultrafiltrate concentration time curve (AUC) for cisplatin was slightly greater in the infusion group, 442+/-26 microg/ml/min, than in the bolus injection group, 340+/-5 microg/ml/min. For monoaqua cisplatin, the AUC was not different between the groups (bolus injection: 30.8+/-1. 5 microg/ml/min, infusion: 34.1+/-3.3 microg/ml/min). A significant ototoxic effect was observed in both groups at 20 and 12.5 kHz, but there was no difference between the groups in the extent of threshold shift. The interindividual variability in susceptibility to ABR threshold shift was far greater than the variability in pharmacokinetics, suggesting that other factors are more important in determining the degree of hearing loss.

Abstract
In an effort to use antineoplastic drug combinations which are active in platinum resistant ovarian cancer or which can induce a second response after a platinum first-line treatment, we conducted a study on 30 ovarian cancer patients previously treated with carboplatin plus cyclophosphamide who were given ifosfamide 5 g/m2 i.v. divided over days 1 to 3 plus mesma combined with cisplatin 100 mg/m2 i.v. divided over days 1 to 3 every 4 weeks as second-line treatment. Eight patients had never entered remission with first-line chemotherapy while 22 patients had tumor recurrence within 6 to 18 months after the end of chemotherapy and their tumors were considered potentially platinum sensitive. Responding patients received 6 courses while palliative treatment for nonresponders was provided. Of the 22 patients with tumor recurrence, 8 patients responded with one partial response (PR) and 7 complete clinical responses (CCR). Two out of the 8 patients with platinum resistant disease demonstrated short lasting PR. Seven patients with CCR underwent second-look operation and in two a pathological CR was documented. Median time to progression was 6 mo (4-12). The median overall survival was 12 mo (4-20). Myelotoxicity despite G-CSF administration was significant with grade 4 leukopenia in 40% and grade 3 thrombocytopenia in 20% of patients. Central nervous system (CNS) toxicity was significant with 30% somnolence, 20% disorientation and an episode of grand-mal epilepsy ascribed to ifosfamide. With a 33% response rate the combination is as effective as new agents employed in relapsed ovarian cancer. Platinum-refractory disease may respond to a lesser degree. The most important determinant of response was the progression-free interval from first-line chemotherapy. Whether patients recurring after carboplatin plus cyclophosphamide have a greater chance to respond to cisplatin plus ifosfamide or vice-versa cannot be supported by the current data and therefore randomized studies should be performed to this end.

Abstract
OBJECTIVE To identify factors predictive of overall survival after first relapse or primary progression in patients with advanced epithelial ovarian cancer. METHODS "Tree-structured prediction of survival for censored survival data" was used to identify the independent prognostic factors in the test group (n = 352) who were the patients from the previously reported Canadian OV.8 trial. A prognostic model was developed using these factors and subjected to validation in the Canadian OV.4 trial cohort (n = 282). RESULTS Based upon three factors, time from diagnosis to first recurrence or progression, tumor grade at diagnosis, and ECOG performance status at original diagnosis, three groups of patients were identified. These were labeled as good, intermediate, and poor prognosis with median survivals post relapse of 18 (12), 6 (5), and 1 (2) months, respectively. The figure in parentheses is the survival in the validation cohort. CONCLUSIONS These prognostic groupings enable us to recommend second-line treatment more logically. The patients in the poor prognosis group have such a limited survival that cancer shrinking therapy should not routinely be offered. In addition the use of the individual predictive factors as stratification factors will help to avoid erroneous conclusions about treatment efficacy.

Abstract
OBJECTIVE The aim of this study was to evaluate the response to salvage treatment in recurrent ovarian cancer treated initially with paclitaxel-based chemotherapy. METHODS A retrospective review of patients with recurrent ovarian cancer treated with surgical debulking and paclitaxel-based chemotherapy was performed. All cases received second-line treatment with a response evaluated by clinical or surgical means. Data analysis was conducted using the SAS statistical package. RESULTS Fifty cases of advanced stage disease were available for review. Patients received paclitaxel and cisplatin or carboplatin with a 72.0% response rate. The median time to recurrence after primary treatment was 6 months. Second-line treatment included cisplatin or carboplatin (50%), Taxol (10%), or lutetium (22%), an intraperitoneal radiolabeled monoclonal antibody targeted to TAG-72. A 52.0% clinical response to salvage treatment was detected. With a median follow-up of 7 months, 68.0% of patients had experienced recurrence or progression of their disease. The median time to second recurrence was 5 months. Cases sensitive to initial paclitaxel-containing chemotherapy responded to any of the salvage treatments more frequently than chemotherapy-resistant tumors (88.5% versus 11.5%, P < 0.05). CONCLUSIONS Recurrent ovarian cancer patients initially treated with paclitaxel-based chemotherapy frequently responded to salvage treatment. However, the duration of response was brief, and hospitalization for treatment-related side-effects was common. Tumor response to initial paclitaxel/platinum treatment was predictive of future response to second-line agents. Current salvage therapies appear to provide little benefit in cases of tumors resistant to primary chemotherapy.

Abstract
From 1984 to 1988, thirty-nine untreated patients with epithelial ovarian cancer received Cisplatin 50 mg/m2, Doxorubicin 50 mg/m2, and Cyclophosphamide 750 mg/m2 (CAP), at 3 weekly intervals. All patients had FIGO stage III or IV tumors except 2 patients with stage IIb and IIc, respectively. After initial surgery 23 patients had residual disease > 2 cm in diameter. Twenty-five patients (64%) were evaluable for response to chemotherapy. Objective responses were observed in 13 out of 25 patients (52%, 95% confidence intervals (CI), 32.42% to 71.58%), 6 patients had a cCR (24%) and 7 had a cPR (28%). Seventeen out of the 39 patients (44%) had a second-look laparotomy. A pCR was achieved in 5 out of 17 patients (29%); a pPR was obtained in 8 patients (47%). Median duration of survival was 41,5 months (range 2-107+); median duration of time to failure was 21 months (range 2-107+). Median disease-free survival was 86 months (range 3,5-107+). Eleven patients (28%) are alive and 9 patients (23%) are free of recurrence at median follow-up of 86 months. Only 4 of 11 long-term survivors had a pCR. In univariate analysis, histology, clinical response to chemotherapy, and the presence of ascites at the time of diagnosis, achieved a significant correlation with survival and time to failure (TTF); in addition, TTF was significantly affected by pathological response to induction chemotherapy. The only important predictors of disease-free survival (DFS) were tumor grade and stage of disease. In multivariate analysis, the presence of ascites was the only significant prognostic factor with respect to survival and TTF. Our study confirms the effectiveness of CAP in the treatment of epithelial ovarian cancer and the relatively poor long term prognosis.

Abstract
Transforming growth factor-alpha (TGF-alpha) is a potent mitogenic polypeptide. It is secreted by a variety of transformed cells and tumors, modifying tumor growth through autocrine or paracrine mechanism. In the present study, serum levels of TGF-alpha were determined by enzyme-linked immunosorbent assay (ELISA) in 27 normal females, 116 patients with benign ovarian tumors, and 42 patients with epithelial ovarian cancers (10 with stage I, 7 with stage II, 19 with stage III, and 6 with stage IV). The ELISA assay could detect a minimum level of serum TGF-alpha concentration at 10 pg/ml. Serum samples were obtained from normal females and from patients with benign or malignant ovarian tumors before initial surgery. The detectable rates were 11% (3/27) in normal females, 28% (32/116) in benign ovarian tumors, and 62% (26/42) in ovarian cancers. The detectable rates in serous and endometrioid ovarian cancers were 71 and 70%, respectively, which were higher than the rate of 33% in mucinous type. However, there was no obvious relationship between the detectability of serum TGF-alpha and the stages of ovarian cancers. The mean concentration of TGF-alpha in ovarian cancer was 159.8 pg/ml, which was significantly higher than 27.7 pg/ml in benign ovarian tumors (P < 0.001) as well as 15 pg/ml in normal females (P < 0.001). The mean concentrations of serum TGF-alpha in stages I to IV ovarian cancers were 133.5, 96.2, 194.8, and 178.3 pg/ml, respectively. The mean concentration of serum TGF-alpha in any two stages of ovarian cancers was not statistically different. In conclusion, measurement of serum TGF-alpha can be used as a supplementary tumor marker to differentiate a malignant ovarian tumor from a benign one. However, the concentration of serum TGF-alpha has no special relation with the stage of ovarian cancer itself. Because of the small number of stage I ovarian cancers with detectable TGF-alpha in the present investigation, it would probably not be feasible to differentiate a stage I ovarian cancer from a benign ovarian tumor based only on the level of TGF-alpha in serum.

Abstract
Reports which analyzed the effects of secondary cytoreductive surgery at second-look laparotomy have often included small numbers of patients who have been treated with a variety of first-line chemotherapy regimens and those who may have progressed on first-line therapy. The purpose of this study was to analyze survival following secondary cytoreductive surgery at second-look laparotomy in patients with advanced ovarian cancer. Review of the surgical data of 153 patients allowed classification of tumor size found at second-look laparotomy and tumor size remaining after cytoreduction. Multivariate analysis evaluated multiple risk factors for survival. Of 153 patients, 124 had macroscopic tumor at second-look laparotomy and 29 had microscopic disease only. Fifteen of 69 (22%) patients were found to have tumor > 1 cm in diameter and were cytoreduced to microscopic residual and 18/69 (26%) were left with 1 cm tumor. Twenty-one of 55 (38%) patients with < or = 1 cm tumor were debulked to microscopic residual. The shortest survival relative to patients found to have microscopic disease at second-look laparotomy was observed among patients whose maximum tumor size remained > 1 cm following second-look laparotomy (relative risk = 3.1, P = 0.0004). No difference in survival was seen between patients found to have microscopic disease and those cytoreduced to microscopic disease (P = 0.24). The risk of death was lower among patients debulked to a lower category (< or = 1 cm debulked to microscopic, relative risk = 0.48, P = 0.02; > 1 cm reduced to < or = 1 cm, relative risk = 0.49, P = 0.02; > 1 cm reduced to microscopic, relative risk = 0.44, P = 0.01). Whether this apparent beneficial effect of cytoreductive surgery at second-look laparotomy reflects the biology of the tumor which allows surgical cytoreduction or the effects of cytoreduction can only be addressed in a randomized prospective trial.

Abstract
BACKGROUND With current standard-dose chemotherapy ovarian cancer is a chemosensitive but not chemocurable disease in the majority of cases. The widely used first-line chemotherapy including a platinum analogue combined with cyclophosphamide results in response rates of 60-80%. However, only 10-20% of patients with advanced disease are alive 5 years after the diagnosis. The efficacy of high-dose chemotherapy supported by autologous stem cell transplantation (ASCT) is currently under intensive investigation. METHODS We report here our initial experiences of the use of high-dose chemotherapy supported by ASCT for patients with high-risk ovarian cancer. Two patients were treated at Uppsala University Hospital in 1992 and four patients at Turku University Central Hospital in 1994. RESULTS The first four patients treated either after heavy previous chemotherapy or recurrent disease relapsed within 5-10 months. Two patients received high-dose therapy as part of first-line treatment. One of them had a relapse 18 months after therapy, the other one has been disease free for 28 months. No toxic deaths occurred, but the patients had neutropenic febrile episodes and moderate to severe gastrointestinal toxicity. CONCLUSIONS Coordinated efforts in Nordic countries are indicated to evaluate the usefulness of high-dose therapy supported by ASCT in the treatment of advanced ovarian cancer.

Abstract
In order to simulate drug resistance observed in the clinic, two cisplatin-resistant cell lines were produced from a murine ovarian reticulosarcoma, M5076 (M5), by pulse (M5/CDDP) and continuous (M5/CDDPc) treatment with cis-diamminedichloroplatinum(II)(CDDP). These cell lines showed a similar stable low level of resistance (approximately 3-fold) to CDDP and cross-resistance to carboplatin, iproplatin and the new alkylating agent tallimustine, but not to L-PAM (L-phenylalanine mustard) and BCNU (1,3-bis(2-chloroethyl)-1-nitrosourea). Collateral sensitivity to two inhibitors of topoisomerase II, VP16 (etoposide) and doxorubicin (Dox), but cross-resistance to the topoisomerase I inhibitor, camptothecin, were observed. The two cell lines were also sensitive to 5-fluorouracil. No increase in the level of glutathione or activity of glutathione S-transferase could be observed in resistant cells compared with the parental M5 cells. Total DNA platination immediately after treatment was similar in the parental and resistant cell lines. Repair of total DNA platination, measured after 24 h of recovery, was undetectable in M5 and M5/CDDP cells, but was 33% in M5/ CDDPc cells. Initial DNA-interstrand cross-links (DNA-ISC) were six times higher in M5 than in M5/CDDP cells, but 24 h after treatment, both lines had completely repaired this damage. M5/ CDDPc cells did not show formation of DNA-ISC at any time after treatment. The two resistant cell lines were tumorigenic when implanted in mice and resistant to CDDP treatment in vivo. The CDDP resistant tumours were not cross-resistant in vivo to L-PAM, BCNU and Dox, which had been active in vitro, nor to tallimustine, which had been cross-resistant in vitro. Mechanisms of resistance in M5/CDDP and M5-CDDPc seem to be based on a lower formation of DNA-ISC combined, for the latter cell line, with a higher repair capacity for total DNA platination.

Abstract
Thirty-two patients with epithelial ovarian cancer received paclitaxel 175 mg/m2, by 3-hour infusion, in this prospective phase 2 study. All patients had relapsed or progressed after initial cisplatin/cyclophosphamide therapy. Thirteen patients received paclitaxel as second line therapy, 14 as third line therapy and 5 as fourth line therapy. One patient was excluded from efficacy analysis, due to a severe anaphylactic reaction to the first cycle of paclitaxel therapy. Of the 31 evaluable patients, complete remission was observed in 3 patients (9.7%) and partial remission in 11 patients (35.5%), with a total response rate of 45.2%. The median survival from diagnosis for the 31 evaluable patients was 32.5 months and the median survival following therapy with paclitaxel was 12.2 months (range 4-27 months). The 3 patients who achieved a complete response remain alive, at greater than 20 months, since commencing paclitaxel. Twelve patients (38.7%) who achieved a partial response, or had stable disease, had a median survival, after paclitaxel treatment, of greater than 18 months. This study confirms the activity of paclitaxel in relapsed ovarian cancer and demonstrates a prolonged survival benefit in greater than one third of this group of patients.

Abstract
Surgery and chemotherapy have contributed to a modest overall survival in patients with epithelial ovarian carcinoma. It is therefore important to pursue novel therapy strategies for this disease that are different from conventional chemotherapy. Tumor infiltrating lymphocytes (TILs) from patients with ovarian carcinoma may represent an active immune response of the host directed against the tumor cells. These TILs can be expanded in vitro in low concentrations of recombinant interleukin-2 (rIL-2) by a few thousandfold. The resulting T-cell lines comprise CD3+CD4+TCR alpha beta + or CD3+CD8+TCR alpha beta + cells, or mixtures of both. These T-cell lines may exhibit either tumor-specific cytotoxicity against autologous tumor cells, or produce cytokines (interferon-gamma, tumor necrosis factor, and granulocyte stimulating factor) either in antigen-dependent (tumor-specific) or an antigen-independent manner. T-cell lines exhibiting primarily autologous tumor-specific cytotoxicity were developed from approximately 50% of the patients. Blocking experiments using appropriate monoclonal antibodies revealed that the CD3/TCR complex on the effector cells and the MHC class I antigens on the tumor cells were involved in the cytolytic process. We have developed a four-step method for the expansion of TILs to large numbers (1 x 10(10) to 1 x 10(11)) sufficient for clinical trials in patients with ovarian cancer. We have conducted a pilot clinical trial to examine the feasibility and clinical effects of intraperitoneal TILs and low-dose rIL-2 in patients with advanced ovarian carcinoma who were refractory to platinum-based chemotherapy. More recently, procedures have been developed for obtaining large numbers of purified CD8+ rIL-2-expanded TILs for the treatment of patients with ovarian carcinoma. The evolution of clinical trials and correlative studies necessary to develop an effective adoptive immunotherapy approach were discussed.

Abstract
BACKGROUND The primary aim was to induce a high number of pCR in early (FIGO IC, IIB + C) - and advanced (FIGO III-IV) - stage ovarian cancer with a surgery plus 4 cycles of cisplatin and melphalan (PAMP) regimen. The second objective was to prevent relapse with WAR in patients in remission after chemotherapy. PATIENTS AND METHODS 218 eligible patients were treated after staging laparotomy with cisplatin 80 mg/sqm i.v. on day 1 and melphalan 12 mg/sqm i.v. on day 2 q 4 weeks. Response was verified by second-look laparotomy. WAR was carried out with the open field technique on a linear accelerator (daily dose: 1.3 Gy, total dose: 29.9 Gy) in patients with pathological or clinical CR or pathological PR with microscopical residual disease. RESULTS 146/218 patients (67%, 95% CI: 61%-73%) responded to PAMP: 56 (26%) achieved pCR, 24 (11%), cCR, 56 (26%) pPR and 10 (5%) cPR (c = clinical, p = pathological). Multivariate analyses revealed that in advanced stages (92 cases in remission), the achievement of pCR was the most important factor for longer time to failure (TTF) and survival. Only 51/118 (43%) patients in remission received WAR. Early-stage patients <= 55 years were more likely to have WAR than patients older than 55 years (77% vs. 23%; p = 0.02). Advanced-stage patients with cCR were less likely to be irradiated than patients with pCR or pPR (10% vs. 51%; p = 0.003). Toxicity of PAMP was acceptable with 10% of WHO grade 4 hematologic toxicity. Acute hematological toxicity of WAR caused interruption (33%) or incompleteness (33%) of irradiation in the majority of patients. CONCLUSIONS PAMP is an effective treatment for advanced ovarian cancer with a 67% response rate after 4 cycles. For the majority of patients in remission, WAR as a consolidation treatment was hardly feasible. For these patients new treatment modalities to consolidate remission are needed.

Abstract
BACKGROUND The purpose of the study was to analyze the determinants of long term survival in women with advanced ovarian cancer and negative second-look laparotomy. METHODS A series of 140 advanced (Stage III-IV) ovarian cancer patients (median age, 54 years; range, 22-74 years) with negative second-look laparotomy after primary surgery and chemotherapy is included in the analysis. At first diagnosis, all patients were treated with radical or debulking surgery. After primary surgery, the patients were treated with a chemotherapy regimen based on cisplatin or carboplatin alone or in combination with other drugs. All second-look laparotomies were performed 6-8 months after first surgery. RESULTS The overall survival rates were 76% at 3 years, 66% at 5 years, and 51% at 8 years. The corresponding rates for disease free survival were 57, 50, and 43%, respectively. Survival rates were better for women with a residual tumor 1 cm or less after primary surgery. The 5-year probability of survival was 78% in this group, compared with 55% in women with a residual tumor more than 1 cm (log rank test, P < 0.05). Survival rates for women with tumor Grade 3 tended to be worse than Grades 1-2, but the difference was only of borderline statistical significance. No relationship emerged between survival and age, histotype, and presence of ascites at diagnosis. Women with a residual tumor 1 cm or less and positive lymph nodes had a 66% 5-year probability of survival, compared with 85% for women with a residual tumor 1 cm or less and negative lymph nodes. This difference was significant (log rank test, P = 0.05). The 5-year survival probabilities were 47 and 58%, respectively, in women with a residual tumor more than 1 cm and positive or negative lymph nodes. CONCLUSIONS This analysis shows a favorable long term survival rate for women with advanced ovarian cancer and complete pathologic response after debulking surgery and postoperative chemotherapy. It further suggests that lymph nodal status is a prognostic factor for women with minimal residual tumor after surgery.

Abstract
Altretamine (hexamethylmelamine) is a cytotoxic antineoplastic agent which appears to require metabolic activation. Metabolic intermediates may act as alkylating agents; however, altretamine is not directly cross-resistant with classical alkylating agents. Objective response rates to orally administered altretamine as salvage therapy in patients with advanced ovarian cancer were 0 to 33%, with disease stabilisation in a further 8 to 78% of patients. Response rates appear to be higher in patients who have responded to previous alkylating agent or cisplatin-based therapy. There is some evidence that addition of altretamine to platinum-based combination regimens used for induction therapy of advanced ovarian cancer may improve long term survival, particularly in patients with limited residual disease. Although altretamine displays some activity in small cell lung cancer, it is unlikely to have any clinical role in the management of non-ovarian cancer. Altretamine appears to be relatively well tolerated, with gastrointestinal, neurological and haematological toxicities being the main dose-limiting adverse effects. However, assessment of accurate incidence rates for these effects is complicated by the use of altretamine with cisplatin. On the basis of the emerging body of clinical evidence, altretamine appears to have a limited role in the treatment of persistent or recurrent advanced ovarian cancer, primarily in patients who are potentially platinum sensitive yet intolerant of platinum analogues. Additionally, altretamine may be added to platinum-based regimens for induction therapy of advanced ovarian cancer. At the doses currently recommended, altretamine offers a reasonably well tolerated regimen that can be administered orally and is suitable for use on an outpatient basis.

Abstract
The methods most often used for follow-up of ovarian cancer are physical examination, CA-125 measurement and ultrasonography or computed tomography. In the present study the role of cul-de-sac aspiration cytology as a supplementary method was evaluated. We analyzed the records of 110 stage I-IV ovarian cancer patients who had undergone cul-de-sac aspiration as a part of their follow-up schedule after the primary treatment. During the median follow-up of 5 years altogether 577 cul-de-sac aspirations were performed with a median interval of 9 months. Only in 2 cases the obtained sample was insufficient for evaluation. Twenty patients had cul-de-sac cytology > or = class III at some point during the follow-up. In 12 cases the preceding or subsequent CA-125 values taken within 3 months were < 35 U/l. In 7 cases CA-125 values increased later, but in 5 cases the tumour marker values remained within normal range during the entire follow-up. Nine out of these 12 patients had a clinical recurrence later on, but 3 patients had no evidence of the disease. Twenty-seven recurrences were detected during the follow-up. Cul-de-sac aspiration cytology was the first or the only indication of recurrence in 9 cases (33%) and is a useful supplementary method in the follow-up of ovarian cancer.

Abstract
Survival (S) and progression-free survival (PFS) were evaluated in 129 advanced ovarian cancer patients, who achieved a macroscopic complete response (112 pathological complete response and 17 microscopic disease) at second-look after platinum-based combination chemotherapy with or without doxorubicin (DX). The impact on S and PFS of age, performance status (PS), stage, histology, grade (G), residual disease after first surgery (RD), chemotherapy regimen, disease status at second-look and consolidation therapy were evaluated by univariate and multivariate analysis. In the 118 months observation period, median S and PFS were 81 and 34 months, respectively. Stage, G, RD, PS and disease status at second-look had significant impact on both S and PFS in univariate analysis, whereas consolidation therapy did not influence outcome. Cox's regression analysis showed that G, RD and PS had an independent impact on PFS. Test for interaction demonstrated no statistically significant relationship between RD, chemotherapy regimen and outcome. In conclusion, advanced ovarian cancer patients with macroscopically complete remission at second-look have a substantial risk of relapse after aggressive treatment. The risk of recurrence was estimated to be maximal in the first 3 years after restaging, and was correlated with poor PS, RD > 2 cm after first surgery and undifferentiated tumour.
