Huang CY, Cheng M, Lee NR, Huang HY, Lee WL, Chang WH, Wang PH. Comparing Paclitaxel-Carboplatin with Paclitaxel-Cisplatin as the Front-Line Chemotherapy for Patients with FIGO IIIC Serous-Type Tubo-Ovarian Cancer. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17072213. [PMID: 32224896 PMCID: PMC7177627 DOI: 10.3390/ijerph17072213] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 03/20/2020] [Accepted: 03/24/2020] [Indexed: 12/11/2022]
Abstract
The use of weekly chemotherapy for the treatment of patients with advanced-stage serous-type epithelial Tubo-ovarian cancer (ETOC), and primary peritoneal serous carcinoma (PPSC) is acceptable as the front-line postoperative chemotherapy after primary cytoreductive surgery (PCS). The main component of dose-dense chemotherapy is weekly paclitaxel (80 mg/m2), but it would be interesting to know what is the difference between combination of triweekly cisplatin (20 mg/m2) or triweekly carboplatin (carboplatin area under the curve 5-7 mg/mL per min [AUC 5-7]) in the dose-dense paclitaxel regimen. Therefore, we compared the outcomes of women with Gynecology and Obstetrics (FIGO) stage IIIC ETOC and PPSC treated with PCS and a subsequent combination of dose-dense weekly paclitaxel and triweekly cisplatin (paclitaxel–cisplatin) or triweekly carboplatin using AUC 5 (paclitaxel–carboplatin). Between January 2010 and December 2016, 40 women with International Federation of Gynecology and Obstetrics (FIGO) stage IIIC EOC, FTC, or PPSC were enrolled, including 18 treated with paclitaxel–cisplatin and the remaining 22 treated with paclitaxel–carboplatin. There were no statistically significant differences in disease characteristics of patients between two groups. Outcomes in paclitaxel–cisplatin group seemed to be little better than those in paclitaxel–carboplatin (median progression-free survival [PFS] 30 versus 25 months as well as median overall survival [OS] 58.5 versus 55.0 months); however, neither reached a statistically significant difference. In terms of adverse events (AEs), patients in paclitaxel–carboplatin group had more AEs, with a higher risk of neutropenia and grade 3/4 neutropenia, and the need for a longer period to complete the front-line chemotherapy, and the latter was associated with worse outcome for patients. We found that a period between the first-time chemotherapy to the last dose (6 cycles) of chemotherapy >21 weeks was associated with a worse prognosis in patients compared to that ≤21 weeks, with hazard ratio (HR) of 81.24 for PFS and 9.57 for OS. As predicted, suboptimal debulking surgery (>1 cm) also contributed to a worse outcome than optimal debulking surgery (≤1 cm) with HR of 14.38 for PFS and 11.83 for OS. Based on the aforementioned findings, both regimens were feasible and effective, but maximal efforts should be made to achieve optimal debulking surgery and following the on-schedule administration of dose-dense weekly paclitaxel plus triweekly platinum compounds. Randomized trials validating the findings are warranted.

Apatinib combined with oral etoposide in patients with platinum-resistant or platinum-refractory ovarian cancer (AEROC): a phase 2, single-arm, prospective study. Lancet Oncol 2018; 19:1239-1246. [PMID: 30082170 DOI: 10.1016/s1470-2045(18)30349-8] [Citation(s) in RCA: 120] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Revised: 04/27/2018] [Accepted: 05/01/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND Anti-angiogenic therapy combined with chemotherapy could improve the outcomes of patients with platinum-resistant ovarian cancer. Apatinib is an oral tyrosine kinase inhibitor that selectively inhibits VEGF receptor 2. We assessed the efficacy and safety of the combination therapy of apatinib and oral etoposide, considering the potential advantage of home administration without hospital admission, in patients with platinum-resistant or platinum-refractory ovarian cancer. METHODS In this phase 2, single-arm, prospective study, we recruited patients aged 18-70 years with platinum-resistant or platinum-refractory ovarian cancer at the Sun Yat-sen University Cancer Center (China). The treatment consisted of apatinib at an initial dose of 500 mg once daily on a continuous basis, and oral etoposide at a dose of 50 mg once daily on days 1-14 of a 21-day cycle. Oral etoposide was administered for a maximum of six cycles. Treatment was continued until disease progression, patient withdrawal, or unacceptable toxic effects. The primary endpoint was the proportion of patients achieving an objective response according to Response Evaluation Criteria in Solid Tumors, version 1.1. We used Simon's two-stage design, and analysed efficacy in the intention-to-treat and per-protocol populations. Safety analyses included enrolled patients who had received at least one dose of study medication, but excluded those without any safety data. This study is registered with ClinicalTrials.gov, number NCT02867956. FINDINGS Between Aug 10, 2016, and Nov 9, 2017, we screened 38 and enrolled 35 patients. At the data cutoff date (Dec 31, 2017), 20 (57%) patients had discontinued the study, and 15 (43%) patients remained on treatment. Objective responses were achieved in 19 (54%; 95% CI 36·6-71·2) of 35 patients in the intention-to-treat population and in 19 (61%; 42·2-78·2) of 31 patients in the per-protocol population. The most common grade 3 or 4 adverse events were neutropenia (17 [50%]), fatigue (11 [32%]), anaemia (ten [29%]), and mucositis (eight [24%]). Serious adverse events were reported in two patients who were admitted to hospital (one patient had anaemia and anorexia; the other patient had increased ascites due to disease progression). No treatment-related deaths were recorded. INTERPRETATION The combination of apatinib with oral etoposide shows promising efficacy and manageable toxicities in patients with platinum-resistant or platinum-refractory ovarian cancer, and further study in phase 3 trials is warranted. FUNDING None.

Abstract
Carboplatin and paclitaxel, delivered on a 3-weekly basis, is the historical standard for the management of advanced epithelial ovarian cancers (EOC). Increased dose intensity, the inclusion of additional active cytotoxic agents and lengthening treatment duration have failed to improve the outcomes seen with standard doses of carboplatin and paclitaxel in the treatment of EOC. Dose-dense (i.e. weekly) delivery of paclitaxel may exploit anticancer mechanisms such as anti-angiogenesis and the induction of apoptosis. Tumour regrowth may be more effectively impaired by the dose-dense delivery of paclitaxel. Non-randomised studies of dose-dense chemotherapy in EOC have been promising, particularly in heavily pretreated and platinum-resistant disease, with reported response rates as high as 60%. Dose-dense paclitaxel also seems to be well tolerated. These observations led to a number of comparative trials of dose-dense paclitaxel chemotherapy, three have been reported and four are ongoing. This review explores the rationale behind dose-dense delivery of paclitaxel and evaluates the results of completed phase III trials.

Abstract
OBJECTIVE Epithelial ovarian cancer is the leading cause of death from gynaecologic cancers in the Western world. If possible, initial cytoreductive surgery is the treatment of choice, followed by adjuvant chemotherapy, usually with a platinum/taxane combination. Increased survival has been recently reported in women who were given adjuvant chemotherapy weekly rather than at three-week intervals, which has been the standard. At our centre, we have been treating patients with advanced ovarian cancer with a dose-dense protocol since March 2010. Treatment is given in an outpatient setting on days 1, 8, and 15 of a 21-day cycle for six cycles. Carboplatin for an AUC of 5 mg/mL/min and paclitaxel 80mg/m² are given on day 1, followed by paclitaxel 80mg/m² on days 8 and 15. Our objective was to determine whether this protocol is a feasible alternative treatment in our population and whether or not the toxicity profile is acceptable. METHODS We performed a chart review of 46 patients undergoing treatment with dose-dense chemotherapy for advanced ovarian cancer. Demographic information, patient characteristics, adverse events, and treatment endpoints were recorded. RESULTS Sixty-one percent of women completed the six-cycle protocol as planned with minimal interruption, which is comparable to the only previously reported trial using this regimen. The most common side effects of treatment were fatigue, neuropathy, and neutropenia. Supplementation with regular magnesium and granulocyte colony-stimulating factor reduced delays. CONCLUSION Dose-dense paclitaxel with carboplatin chemotherapy for the treatment of advanced ovarian cancer shows promise in terms of progression-free and overall survival. We have shown this protocol to be practical and feasible in our population.

Abstract
BACKGROUND Weekly paclitaxel/cisplatin is effective in platinum-resistant epithelial ovarian cancer (EOC). To reduce toxicity, paclitaxel/cisplatin was replaced by paclitaxel/carboplatin. PATIENTS AND METHODS Patients with progressive EOC after prior 3-weekly paclitaxel/carboplatin were treated with six cycles weekly paclitaxel 90 mg/m(2) and carboplatin area under the curve (AUC) 4 mg/ml/min, followed by six cycles 3-weekly paclitaxel/carboplatin. End-points were progression free survival (PFS), overall survival (OS), response rate (RR) and toxicity. RESULTS Median progression free interval after last platinum was 9 (0-81) months in 108 patients; 43 were platinum-resistant, of whom 13 started weekly paclitaxel/carboplatin <6 months after progression. During 633 weekly cycles grade 3/4 toxicity included; thrombocytopenia 8%, neutropenia 30%, febrile neutropenia 0.5%. Non-haematologic toxicity was low. Treatment was delayed in 16%, and dose reduced in 2% of cycles. RR was 58% for platinum-resistant and 76% for platinum-sensitive patients, median PFS were 8 (range 1-21) and 13 (1-46) months, median OS 15 (1-69) and 26 (4-93) months, respectively. The 13 platinum-resistant patients with a platinum-therapy free interval <6 months had a significant shorter PFS (4 versus 10 months, p=0.035) and OS (9 versus 15 months, p=0.002). CONCLUSION Six cycles weekly paclitaxel/carboplatin followed by six 3-weekly cycles is well-tolerated and highly active in platinum-resistant and platinum-sensitive patients.

Abstract
OBJECTIVE The objective of the study was to evaluate the response of weekly paclitaxel/carboplatin in patients with primary advanced or recurrent endometrial cancer. METHODS Eighteen cycles of paclitaxel (60 mg/m²) and carboplatinum (area under the plasma concentration-time curve, 2.7) were administered weekly. Response rates were evaluated according to Response Criteria in Solid Tumors criteria. RESULTS Paclitaxel/carboplatin weekly was administered to 29 patients. Median age was 62 years (range, 44-80 years). Main histopathologic types were serous/clear cell (n = 16) and endometrioid (n = 9). Patients were divided into a chemonaive group (n = 16) (group 1) and a group with previous chemotherapy (n = 13) (group 2). Response rate for group 1 was as follows: partial remission, n = 8 (50%); stable disease, n = 1 (6%); and progressive disease, n = 7 (44%). Response for group 2: partial remission, n = 5 (39%), and progressive disease, n = 8 (62%). Median progression-free survival and overall survival were 9 months (range, 5-27 months) and 12 months (range, 2-27 months), respectively, for group 1 and 8 months (range, 6-10 months) and 9 months (range, 2-18 months), respectively, for group 2.Overall 411 weekly treatments were administered. Because of grade 4 bone marrow toxicity, treatments needed to be adjusted as follows: dose reduction of 50% to 75%, n = 81 (20%); dose delay, n = 66 (16%); not administered, n = 6 (1%); and changed to paclitaxel/cisplatin, n = 4 (1%). Twenty-three patients (85%) needed treatment adjustment because of toxicity. Neutropenic fever occurred in 1 patient (4%). The most common nonhematologic toxicities were grade 1 to 2 fatigue (89%) and grade 2 nausea (37%). Seven percent had grade 2 neuropathy. No grade 2 alopecia occurred. CONCLUSIONS Paclitaxel/carboplatin weekly seems effective, however, with a considerable hematologic toxicity. Larger trials are needed to confirm these data.

Abstract
Despite the initially high response rate to standard front-line debulking surgery followed by platinum-based chemotherapy, the relapse rate in ovarian cancer is high and many patients will recur within 6 months of completing platinum based treatment. These patients may still require further chemotherapy despite being considered "platinum resistant". In this setting, response rates to conventionally scheduled second line platinum and non-platinum agents is low, ranging between 5% and 15%. There is an emerging body of evidence that in this scenario, chemotherapeutic activity can be enhanced using unconventionally scheduled "dose-dense" platinum and non-platinum based regimens with improved response rates of up to 65%. Randomised studies to evaluate the impact of this approach on survival in recurrent, platinum resistant disease are urgently required to confirm the promising phase II findings if there is to be a change in the standard of care of patients with platinum resistant disease. In this review we discuss the evolving strategies to overcome resistance in patients with platinum resistant ovarian cancer with a particular focus on alterations in dose schedule as a means of reversing platinum resistance.

Abstract
Several studies in the past have tried to improve the prognosis of ovarian cancer by increasing the dose intensity of platinum. Only 2 out of 12 randomized studies showed survival benefit at the cost of significant long-term toxicity. Dose-dense induction therapy with combined weekly paclitaxel (at a dose of 90 mg/m(2)) and weekly carboplatin [at an area under the curve (AUC) of 4 mg·ml/min] followed by 3-weekly paclitaxel/carboplatin was very effective in platinum-resistant patients (response 58%, progression-free survival 10 months). In first-line, however, no survival benefit was found with the same dose-dense weekly paclitaxel/carboplatin regimen over standard-dosed 3-weekly paclitaxel/carboplatin in a randomized study. Very recently, the Japanese Gynecologic Oncology Group (JGOG) study no. 3016, randomizing patients in first-line between dose-dense weekly paclitaxel 80 mg/m(2) plus 3-weekly carboplatin AUC 6 and 3-weekly paclitaxel/carboplatin, showed a significant increase in progression-free survival (median 28 versus 17.2 months in the control arm; hazard ratio for progression, 0.71; 95% confidence interval, 0.58-0.88; P=0.0015). The 3-year overall survival was 72% versus 65% (P=0.03), respectively. The hematologic toxicity was substantial in both arms and substantially higher than observed with the weekly paclitaxel/carboplatin induction regimen. Many patients had treatment delays, dose reductions and stopped treatment prematurely. The JGOG 3016 study is the only dose-dense study with such a significant survival benefit. It is also the only dose-intensity study performed in Asian patients. Genotypes and phenotypes are thought to represent important determinants of drug efficacy in ovarian cancer. Therefore, confirmatory studies with this JGOG regimen together with translational research are needed in both Caucasian and Asian patients.

Abstract
Notwithstanding continuing efforts to improve the primary treatment for ovarian cancer, most patients will ultimately develop recurrent disease. The benefits of detection and early systemic treatment of recurrence are now in doubt following the presentation of the MRC/EORTC CA125 surveillance trial. The impact of secondary cytoreductive surgery on survival requires more investigation. The role of antiangiogenic and other biological agents such as PARP inhibitors is becoming increasingly important for patients as an addition or alternative to the more conventional cytotoxic therapies available. Uncertainties and choices abound both in the treatment of recurrent ovarian cancer and the timing of such interventions. This article not only explores how to treat these patients but also the controversial issue of when to treat. Educating and involving the patient in decisions about their treatment options is of paramount importance.

Abstract
BACKGROUND Platinum agents have shown demonstrable activity in the treatment of patients with platinum resistant, recurrent ovarian cancer when delivered in a "dose-dense" fashion. However, the development of thrombocytopenia limits the weekly administration of carboplatin to no greater than AUC 2. Paclitaxel has a well-described platelet sparing effect however its use to explicitly provide thromboprotection in the context of dose dense carboplatin has not been explored. METHODS We treated seven patients with platinum resistant ovarian cancer who had previously received paclitaxel or who had developed significant peripheral neuropathy precluding the use of further full dose weekly paclitaxel. RESULTS We were able to deliver carboplatin AUC 3 and paclitaxel 20 mg/m2 with no thrombocytopenia or worsening of neuropathic side-effects, and with good activity. CONCLUSIONS We conclude that this regimen may be feasible and active, and could be formally developed as a "platinum-focussed dose-dense scaffold" into which targeted therapies that reverse platinum resistance can be incorporated, and merits further evaluation.

Abstract
Recombinant granulocyte colony-stimulating factor (G-CSF) is used to accelerate recovery from chemotherapy-induced myelosuppression. G-CSF has been recently shown to stimulate angiogenesis mediated by several types of bone marrow-derived cell populations. To investigate whether G-CSF may alter tumor response to therapy, we studied Lewis lung and EMT/6 breast carcinomas in mice treated with paclitaxel (PTX) chemotherapy in combination with G-CSF. We compared the results obtained to mice treated with PTX and AMD3100, a small-molecule drug antagonist of CXCR4 which, like G-CSF, can be used to mobilize hematopoietic cells. We show that PTX combined with G-CSF treatment facilitates revascularization, leading to an improvement in blood perfusion in LLC tumors, and a decrease in hypoxia in EMT/6 tumors, thus enhancing tumor growth in comparison to PTX or PTX and AMD3100 therapies. We found that hemangiocytes but not Gr-1(+) CD11b(+) cells colonize EMT/6 tumors after treatment with PTX and G-CSF, but not PTX and AMD3100, and therefore may contribute to angiogenesis. However, increases in hemangiocyte colonization were not observed in LLC PTX and G-CSF-treated tumors, suggesting distinct mechanisms of tumor revascularization after G-CSF. Overall, our observations suggest that despite its known considerable clinical benefits, G-CSF might contribute to tumor revascularization by various mechanisms, and diminish the antitumor activity of chemotherapy, an effect that can be prevented by AMD3100.

Abstract
Weekly paclitaxel is a highly active and well tolerated regimen that is increasingly being adopted for the treatment of relapsed ovarian cancer. This regimen is usually administered at 80-90 mg/m(2)/week, and the use of a 1 h infusion helps minimize myelosuppression. When compared with the 3-weekly schedule, weekly paclitaxel is better tolerated, with a reduced frequency of grade 3-4 toxic effects. Single-agent weekly paclitaxel for relapsed ovarian cancer yields response rates in the range of 20-62%; however, response duration can be short. Responses to weekly paclitaxel have been observed in patients whose tumors are resistant to 3-weekly paclitaxel. The level of activity of weekly paclitaxel for relapsed disease has led to its detailed evaluation in the first-line setting, and interest has been enhanced by the results of a Japanese Gynecological Oncology Group study that demonstrated a survival advantage for weekly paclitaxel compared with 3-weekly paclitaxel in combination with carboplatin as initial treatment. The enhanced efficacy of weekly paclitaxel may be due to greater drug exposure, a direct antiangiogenic effect, or both. Current research topics include the combination of weekly paclitaxel with molecular-targeted agents and the use of molecular profiling to better select patients for treatment.

Abstract
BACKGROUND The objective of this study was to assess activity and toxicity in patients with newly diagnosed, advanced-stage epithelial ovarian cancer (EOC) who were receiving dose-intense paclitaxel, cyclophosphamide, cisplatin, and filgrastim delivered with a flexible dosing schedule. METHODS Patients with stage III/IV EOC received cyclophosphamide 750 mg/m(2), followed by a 24-hour infusion of paclitaxel 250 mg/m(2) and cisplatin 75 mg/m(2) on Day 2. Filgrastim began on Day 3 at 10 microg/kg daily for 9 days. Patients received 6 cycles of all drugs. Those who achieved a pathologic complete response or had microscopic residual disease at the conclusion of 6 cycles of therapy received an additional 2 to 4 cycles of paclitaxel with cyclophosphamide. Patients who had an objective response continued on cyclophosphamide and paclitaxel. RESULTS Sixty-two patients were enrolled. Thirty-two of 62 patients had stage IIIC disease, and 26 of 62 patients had stage IV disease. According to an intent-to-treat analysis, 55 patients (89%) experienced a clinical complete remission. At a median potential follow-up of 11.4 years, the median progression-free survival was 18.9 months, and the median survival was 5.4 years. The most serious toxicity was grade 3/4 neutropenic fever (35%). Although all participants developed peripheral neuropathy, improvement in neuropathic symptoms began with the decrease or cessation of paclitaxel. CONCLUSIONS The studied regimen yielded a high response rate and encouraging overall survival. The current data and those reported by the Japanese Gynecologic Oncology Group suggest that further study is warranted of dose-dense or dose-intense paclitaxel regimens in women with newly diagnosed, advanced-stage EOC.

Abstract
In a group of 6 BRCA-related ovarian cancer patients presenting with clinical relapse, paclitaxel-carboplatin (TC) in a dose-dense regimen was administered to evaluate the response and tolerability compared with those of the sporadic group and of the patients using a regimen administered every 3 weeks. All patients were carboplatin sensitive at the time of first relapse: 4 patients showed intermediate sensitivity (6-12 months), and 2 patients were truly carboplatin sensitive (>12 months) at first relapse and first administration of a TC dose-dense regimen. A total of 14 dose-dense regimens were administered in a median 5th line (range, 2nd-10th line). A median of 2 dose-dense regimens (range, 1-4) was given per patient. After first administration of the TC dose-dense regimen (median, 3rd line), this resulted in response in all patients: complete remission in 33% and partial remission in the remaining 67%. Furthermore, after another consecutive line of TC dose-dense regimen, 100% response (75% with partial remission and 25% with complete remission) was reached. The results are encouraging and support the observation of extreme carboplatin sensitivity of BRCA-related ovarian cancer. The use of a TC dose-dense regimen might be even more effective.

Abstract
OBJECTIVE To evaluate the response of dose-dense paclitaxel/carboplatin (TC) patients with primarily advanced or recurrent endometrial cancer. METHODS Six courses of paclitaxel (90 mg/m2) and carboplatinum (area under the curve, 4) on days 1 and 8 every 3 weeks were administered. Response rates were evaluated according to the response evaluation criteria in solid tumors. RESULTS Dose-dense TC was administered to 42 patients. The median age was 63.9 years (range, 41-81 years). The main histopathologic types were serous/clear cell (n = 27) and endometrioid (n = 13). The patients were divided in 2 groups: chemotherapy-naive group (n = 28, group 1) and a group with previous chemotherapy (n = 14, group 2).The responses for group 1 were as follows: 11 (39 %) complete response, 9 (32%) partial response, and 2 (7%) stable disease. The responses for group 2 were 1 (7%) complete response, 2 (14%) partial response, and 6 (43%) stable disease. Treatment-related death occurred in 1 patient (7%) because of neutropenia and nephrotoxicity.Progression-free survival for group 1 was 10 months (range, 4-19 months). At time of analysis, 57% of the patients were still alive after a median follow-up of 10 months (range, 4-21 months). Progression-free survival for group 2 was 11 months (range, 4-19 months).Because of grades 3 and 4 hematologic toxicity, treatment adjustments were as follows: 49 (18%) and 18 (19%) dose reductions (carboplatin area under the curve, 2-3), 35 (13%) and 14 (15%) dose delays, and 8 (3%) and 6 (6%) treatments were not administered on day 8 for groups 1 and 2, respectively. CONCLUSIONS Administration of dose-dense TC resulted in a response rate of 71% in chemotherapy-naive patients. Treatment modifications due to toxicity were frequent, but severe complications such as neutropenic fever occurred in a similar incidence as other reported 3-weekly regimens.

Abstract
Objectives This article reviews recent data on the biology, pathogenesis and pathophysiology of the different entity of epithelial ovarian cancer (EOC). Study design The present article reviews the English language literature for screening, epidemiology, clinical diagnosis, natural history, preclinical and clinical trials, and promising molecular targets on EOC, particularly for clear cell EOC (cEOC) based on the gene expression profiling studies. Results Prospective ovarian cancer screening trials in Japan showed that (1) serous-type EOC (sEOC) may exhibit a rapid progression possibly through de novo carcinogenesis, (2) the EOC risk was elevated significantly among patients with ovarian endometrioma (SIR = 8.95), (3) advancing age (>40 years) and the diameter of endometriomas (>9 cm) were independent predictors of development of EOC, (4) the benign-appearing ovarian masses are present several years before the EOC diagnosis in patients with endometriosis-associated EOC, and (5) the slightly elevated CA125 level is also typically present many years (>3 years) before the diagnosis in these patients. Upregulation of HNF-1beta and PLK-Emi1 genes were specifically detected in cEOC. In addition, the therapy currently used in renal cell carcinoma (RCC) should be considered as an attractive therapeutic option for cEOC. Conclusions Ovarian endometrioma could be viewed as a neoplastic process, particularly in perimenopausal women. Understanding the mechanisms of endometriosis development and elucidating its pathogenesis and pathophysiology are intrinsic to prevention and the search for effective therapies of endometriosis-associated EOC.

Abstract
Background:The aim of the study was to assess the efficacy of pegylated liposomal doxorubicin (PLD) and oxaliplatin in patients affected by relapsed epithelial ovarian cancer with a family history of BRCA and p53 mutations.Methods:Seventy-two women received a median of 7.5 courses of PLD at 30 to 35 mg/m2 plus oxaliplatin at 70 mg/m2, and associations between BRCA1/2 and TP53 status and overall survival (OS) were determined. Thirty-eight had a short platinum-free interval (PFI; <12 months), and 34 had a long PFI (≥12 months).Results:Nine patients had BRCA1 mutations, and 1 had a BRCA2 mutation. Platinum sensitivity was associated with OS (P = 0.0001). At a median follow-up of 9.3 months, objective response rate, median time to progression, and OS were 47.3%, 5.8 months, and 12.9 months, respectively, in short PFI compared with the 76.5%, 11.5 months, and 47.7 months in long PFI. p53 status did not correlate to these parameters. The median time to progression was 11.5 months for high-risk patients versus 6.5 months for patients with sporadic cancer (P = 0.0188), and the median OS from the start of treatment was 48.7 and 16.2 months (P = 0.0032), respectively. Toxicity was mostly grade 1 or 2.Conclusions:High response rates in the long-PFI patients indicate that this treatment is beneficial and well tolerated. Platinum sensitivity and positive family history and/or a BRCA1/BRCA2 mutation are a useful predictor of response.

Abstract
There is increasing evidence of the efficacy of dose-dense therapy in the management of platinum-resistant/refractory ovarian cancer. We report our experience of extended weekly carboplatin and paclitaxel in this population group. Twenty patients with platinum-resistant/refractory ovarian cancer received carboplatin AUC 3 and paclitaxel 70 mg m−2 on day 1, 8, 15 q 4 weekly for six planned cycles. Toxicity was assessed using Common Toxicity Criteria. Response was evaluated using radiological and CA125 criteria. Median age was 61 years (range 40–74 years). Median number of prior therapies is three (range 1–8). Response rate was 60% by radiological criteria (RECIST) and 76% by CA125 assessment. Grade 3 toxicities consisted of neutropenia (29% of patients) and anaemia (5%). One patient experienced grade 4 neutropenia. No grade 3/4 thombocytopaenia was reported. Fatigue, nausea and peripheral neuropathy were the most frequent non-hematological side effects. Median progression-free survival was 7.9 months and overall survival was 13.3 months. The dynamics of response to dose-dense therapy were as rapid as with front-line therapy within the same patient. This dose-dense regimen can be extended to at least 18 weekly cycles over 6 months and is well tolerated with high response rates in heavily pre-treated, platinum-resistant ovarian cancer. It forms a highly active and tolerable cytotoxic scaffold to which molecular-targeted therapies can be added in platinum-resistant ovarian cancer.

Abstract
TheInternational Symposium on Advanced Ovarian Cancer: Optimal Therapywas founded by Dr. Andrés Poveda and Prof. Jan B. Vermorken, and each edition has been directed by them. The 6th edition was held on March 2, 2007. This symposium is organized every other year by GEICO (Grupo Español de Investigación de Cáncer de Ovario/Spanish Ovarian Cancer Research Group), under the auspices of the Spanish Society of Medical Oncology (SEOM), the Gynecologic Cancer Intergroup (GCIG), and the European Society of Medical Oncology (ESMO) Educational Committee for its Medical Oncology Recertification Approval (ESMO/MORA) Program. One hundred and fifty people attended the symposium's 1st edition, held in 1996. Since then, the interest in this meeting has increased. Last year, almost three hundred people coming not only from Spain but also from Europe, North and Latin America, Asia, and Australia were present in the symposium. This is a great challenge for us. Some important international cooperative groups from Europe, America, and Australia collaborate with this symposium, such as GOG, NCIC, EORTC, AGO, Scottish Group, ICON, GINECO, NSGO, ANZGOG, and others.

Abstract
OBJECTIVE The purpose of this study was to evaluate the "Leuven" dose-dense regimen in recurrent ovarian cancer. METHODS Six courses of paclitaxel (90 mg/m(2)) and carboplatinum (AUC 4) on d1 and d8 every 3 weeks were administered. Response rates were determined using RECIST and Gynaecological Cancer Intergroup (GCIG) CA 125 criteria. Platinum resistance was defined as progression during or within 6 months after platinum-based chemotherapy. RESULTS Thirty-three patients were included with a median number of prior treatment regimens of 2. Nine patients were platinum-resistant and 24 were platinum-sensitive. Three of 8 patients in the platinum-resistant group and 16 of 21 patients in the platinum-sensitive group achieved an evaluable response according to RECIST. According to the GCIG CA 125 criteria 3 of 7 patients in the platinum-resistant and 17 of 19 patients in the platinum-sensitive patients responded. In the entire patient population evaluable for response (n=29), the median progression-free survival (PFS) was 9 months; the median overall survival (OS) was 18 months. Median PFS was 6.75 months for the platinum-resistant and 10.5 months for the platinum-sensitive group. The median OS was 8 months in the platinum-resistant and not yet reached in the platinum-sensitive group. Toxicity was mostly bone marrow-related with neutropenia grade 3/4 in 34% and neutropenic fever in 2% of courses. Dose reduction was necessary in 25% of patients. Nausea and vomiting and fatigue were the most frequent non-hematological side effects. CONCLUSION Dose-dense paclitaxel and carboplatin offers a well-tolerated regimen with high response rates even in heavily pre-treated and platinum-resistant ovarian cancer.
