ObjectiveSurgical management of advanced ovarian cancer often requires low modified posterior pelvic exenteration (MPE) to achieved complete resection. The aim of this study was to evaluate the morbidity of MPE at the time of primary cytoreductive surgery (PCS) and interval cytoreductive surgery (ICS) after neoadjuvant chemotherapy.Materials and MethodsFrom 2001 to 2009, 63 patients underwent MPE for advanced ovarian cancer. We analyzed and compared surgical characteristics and postoperative courses between PCS and ICS.ResultsModified posterior pelvic exenteration was performed during PCS for 50 patients (79%) and during ICS for 13 patients (21%). Complete cytoreduction was achieved in 80% of patients (84% in the PCS group and 69% in the ICS group; ns). There was no significant difference between the PCS and ICS groups in the type and the rate of standards or radical surgical procedures. Patients with ICS had a shorter length of stay in the intensive care unit (0.9 vs 2.7 days; P = 0.009), but there was no difference in the total length of hospitalization (P = 0.94). The global rate of postoperative complications was 76%. No differences were found between the 2 groups in digestive or extradigestive complications, iterative surgery, or interventional radiology procedures. The median overall survival was 49.4 months in the PCS group and 27.1 months in the ICS group (P = 0.27), and the median progression-free survival time in both groups was 20 months.ConclusionsThere was no difference in the occurrence of postoperative complications between PCS and ICS, especially in morbidity related to MPE. The specific morbidity of this surgical procedure remained low compared with the overall morbidity in cases of extensive surgery.

Abstract Background Systematic retroperitoneal lymphadenectomy has been widely used in the surgical treatment of advanced ovarian cancer patients; nevertheless, the effect remains controversial. Thus, the current study was carried out aiming to evaluate the benefit of systematic retroperitoneal lymphadenectomy in such patients with optimal cytoreduction. Methods Patients with advanced ovarian cancer (International Federation of Gynecology and Obstetrics stage III-IV) admitted and treated in Zhejiang Cancer Hospital from January 2004 to December 2013 were enrolled and reviewed retrospectively. All patients were optimally debulked (residual tumor <1 cm or absent) and divided into two groups. Group A (n =170) (no-lymphadenectomy group): patients did not undergo lymph node resection; lymph nodes resection or biopsy were selective. Group B (n=240): patients underwent systematic retroperitoneal lymphadenectomy. Results A total of 410 eligible patients were enrolled in the analysis. The median age was 51 years (range: 28–72). The 5-year overall survival (OS) and 2-year progression-free survival (PFS) rates were 78% and 24% in the no-lymphadenectomy group and 76% and 26% in the lymphadenectomy group (P=0.385 and P=0.214, respectively). Subsequently, there was no significant difference in 5-year overall survival and 2-year progression-free survival between the two groups stratified to histological type (serous or non-serous type), the clinical evaluation for lymph nodes (negative) or with macroscopic peritoneal metastasis beyond pelvic (IIIB-IV). Multivariate Cox regression analysis indicated that systematic retroperitoneal lymphadenectomy was not a significant factor affecting survival of patients. Patients in the lymphadenectomy group had a higher incidence of postoperative complications (incidence of infection treated with antibiotics was 21.7% vs. 12.9% [P=0.027]; incidence of lymph cysts was 20.8% vs. 2.4% [P < 0.001]). Conclusions Our study showed that systematic retroperitoneal lymphadenectomy did not significantly improve survival in advanced ovarian cancer patients with residual tumor <1 cm or absent after cytoreductive surgery, and were associated with a higher incidence of postoperative complications.

Актуальность. Для современной клинической онкологии одной из важнейших целей является развитие персонифицированного подхода в лечении онкологических пациентов. Это связано с высоким уровнем токсичности химиотерапевтических лекарственных средств. Ключевыми препаратами, использующимися в схемах химиотерапии при раке яичников, являются производные платины, сочетающие высокую эффективность и столь же высокую токсичность. Это делает актуальным поиск маркеров чувствительности к данной группе препаратов. Целью данной работы было изучение статуса полиморфных маркеров генов XRCC1, ERCC2 и CDKN1A и их связи с длительностью времени без прогрессирования (ВБП), которое является суррогатным клиническим маркером чувствительности к производным платины при раке яичника. Материалы и методы. В исследование были включены 26 больных распространенным раком яичника (II-IV стадии), у которых до начала химиотерапии, при первичной циторедуктивной операции, был произведен забор образцов опухолевой ткани. После операции все больные получили стандартную химиотерапию с использованием паклитаксела и препаратов платины. Из образцов опухолевой ткани выделяли ДНК с помощью набора Diatom DNA Prep 400 (Россия). Определение статуса полиморфных маркеров Gln399Arg гена XRCC1, Lys751Gln гена ERCC2 и Ser31Arg гена CDKN1A проводили методом ПЦР-ПДРФ и подтверждением результата методом ПЦР в реальном времени с последующим анализом кривых плавления продукта ПЦР. Статус маркеров был сопоставлен с длительностью ВБП. Результаты. Нами выявлена тенденция к большей продолжительности ВБП при наличии аллеля Gln маркера Gln399Arg гена XRCC1 (медиана ВБП составляла 14,1 мес. у больных с наличием аллеля Gln в сравнении с 10,9 мес. в подгруппе больных с отсутствием аллеля Gln, р = 0,095). В подгруппе больных, которым была проведена оптимальная циторедуктивная операция, носительство минорного аллеля Arg маркера Ser31Arg гена СDKN1A ассоциировалось с уменьшением медианы ВБП (19,1 и 12,8 мес. при отсутствии и наличии аллеля Arg соответственно, р = 0,035). Вывод. Выявлена взаимосвязь статуса полиморфных маркеров генов XRCC1 и CDKN1A с длительностью ремиссии после платиносодержащей химиотерапии рака яичника, что делает целесообразным дальнейшее изучение данных молекулярно-генетических факторов на более репрезентативной группе больных раком яичника. Background: The most important goal of current clinical oncology is personalized treatment primarily due to high toxicity of chemotherapeutic drugs. The key drugs used in chemotherapy of ovarian cancer are platinum derivatives, which are both highly effective and highly toxic. Therefore, searching for sensitivity markers for this group of drugs is very relevant. The aim of this work was to study polymorphic markers of XRCC1 and ERCC2 DNA repair genes and the cell cycle regulation gene, CDKN1A, and their relationship with progression-free survival time (PFS), which is a surrogate clinical marker for sensitivity of ovarian cancer to platinum drugs. Materials and methods. The study included 26 patients with advanced ovarian cancer (stage II-IV). Tumor samples were withdrawn from patients before the onset of chemotherapy, during the primary cytoreductive surgery. After surgery, all patients received a standard chemotherapy with paclitaxel and platinum drugs. DNA was isolated from tumor tissue samples using a Diatom DNA Prep 400 kit (Isogen, Russia). The polymorphic markers, Gln399Arg of the XRCC1 gene, Lys751Gln of the ERCC2 gene, and Ser31Arg of the CDKN1A gene were analyzed by PCR-RFLP and real-time PCR melting curves analysis as a reference. The marker status was compared with the duration of PFS. Results. A tendency towards longer duration of PFS was observed in the presence of the Gln allele of Gln399Arg XRCC1 marker (median PFS, 14.1 months in patients with the Gln allele vs. 10.9 months in the subgroup without the Gln allele; p = 0.095). In the subgroup with optimal cytoreductive surgery, carrying the minor Arg allele of the CDKN1A gene Ser31Arg marker was associated with duration of PFS. In the presence of the minor Arg allele, the PFS duration after platinum-containing chemotherapy was statistically significantly decreased (median PFS, 19.08 months in the absence of Arg allele vs. 12.82 months in the presence of Arg allele, p = 0.035). Conclusion. Polymorphic markers of XRCC1 and CDKN1A genes were found to be related with remission duration after platinum-containing chemotherapy of ovarian cancer. This suggests advisability of further studies of these molecular genetic factors on a representative group of patients with ovarian cancer.

Ovarian cancer remains the most lethal gynecological malignant tumor, with relapse occurring in approximately 70% of advanced cases. Anlotinib is an oral small-molecule multi-targeted tyrosine kinase inhibitor that can resist neoangiogenesis and inhibit tumor growth. Previous research demonstrated clinical antitumor activity of anlotinib in various cancers. We report the case of an elderly woman with advanced ovarian cancer who received anlotinib after failure of multiple-line chemotherapy. A partial response was observed after six cycles of anlotinib monotherapy, with a reduction in the size of the metastases and significantly decreased serum CA125 levels from 1832.7 U/mL to 118.7 U/mL. She continued to take anlotinib, with a progression-free survival time of more than 4 months. Only mild hypertension was observed during the treatment. Anlotinib monotherapy may be a novel therapeutic option for patients with advanced ovarian cancer.

After primary surgery, 125 patients with epithelial ovarian cancer (International Federation of Gynaecology and Obstetrics [FIGO] 1c + IIb + IIc = 22 patients, FIGO III = 82 patients, FIGO IV = 21 patients) were randomly allocated to receive PC (cisplatin 50 mg/m2 + cyclophosphamide 600 mg/m2 on day 1 every 28 days) (corrected) or PAC (PC + doxorubicin 45 mg/m2). After six cycles, patients clinically disease-free or with resectable residual disease were submitted to second-look surgery. After restaging, patients in surgical complete response (CR) stopped treatment while those responding partially (PR) received six more courses; patients whose disease progressed were excluded from the study. Among patients with measurable disease, the following clinical response rates were observed: PC = 20% CR, 34.3% PR, 14.3% stable disease, and 31.4% progression; PAC = 40.6% CR, 15.6% PR, 12.5% stable disease, and 31.3% progression. In the 75 patients submitted to second look, the results have been the following: PC = 39.5% CR, 36.8% PR, 7.9% stable disease, and 15.8% progression; PAC = 62.2% CR, 18.9% PR, 10.8% stable disease, and 8.1% progression. The difference in surgical complete response in favor of the PAC regimen is significant (P less than .05). Median survival and progression-free survival were 800 and 400 days, respectively, for PAC arm; median survival and progression-free survival were 680 and 380 days, respectively, for PC. These differences are not significant. Probability of survival was affected by FIGO stage, amount of residual disease, histology, performance status, and response at second look, while no influence was observed according to grade of tumor differentiation and age. Our results demonstrate the usefulness of doxorubicin in terms of surgical CR.

PurposePazopanib is an oral, multikinase inhibitor of vascular endothelial growth factor receptor (VEGFR) -1/-2/-3, platelet-derived growth factor receptor (PDGFR) -α/-β, and c-Kit. Preclinical and clinical studies support VEGFR and PDGFR as targets for advanced ovarian cancer treatment. This study evaluated the role of pazopanib maintenance therapy in patients with ovarian cancer whose disease did not progress during first-line chemotherapy.Patients and MethodsNine hundred forty patients with histologically confirmed cancer of the ovary, fallopian tube, or peritoneum, International Federation Gynecology Obstetrics (FIGO) stages II-IV, no evidence of progression after primary therapy consisting of surgery and at least five cycles of platinum-taxane chemotherapy were randomized 1:1 to receive pazopanib 800 mg once per day or placebo for up to 24 months. The primary end point was progression-free survival by RECIST 1.0 assessed by the investigators.ResultsMaintenance pazopanib prolonged progression-free survival compared with placebo (hazard ratio [HR], 0.77; 95% CI, 0.64 to 0.91; P = .0021; median, 17.9 v 12.3 months, respectively). Interim survival analysis based on events in 35.6% of the population did not show any significant difference. Grade 3 or 4 adverse events of hypertension (30.8%), neutropenia (9.9%), liver-related toxicity (9.4%), diarrhea (8.2%), fatigue (2.7%), thrombocytopenia (2.5%), and palmar-plantar erythrodysesthesia (1.9%) were significantly higher in the pazopanib arm. Treatment discontinuation related to adverse events was higher among patients treated with pazopanib (33.3%) compared with placebo (5.6%).ConclusionPazopanib maintenance therapy provided a median improvement of 5.6 months (HR, 0.77) in progression-free survival in patients with advanced ovarian cancer who have not progressed after first-line chemotherapy. Overall survival data to this point did not suggest any benefit. Additional analysis should help to identify subgroups of patients in whom improved efficacy may balance toxicity (NCT00866697).

Debulking surgery associated with chemotherapy represent the backbone of ovarian cancer therapy. Adding bevacizumab has improved survival. Recently, PARP inhibitors were added in the first line as maintenance treatment for the patients who achieve a complete or partial response. These drugs act by blocking the activity of the PARP enzyme responsible for base-excision repair, and have shown positive responses when used for tumors lacking homologous recombination. Olaparib, niraparib and veliparib were evaluated and showed an increase in the duration of progression-free survival: 22.1 months (hazard ratio [HR] = 0.59), 13.8 (HR = 0.62) and 23.5 (HR = 0.68) with olaparib, niraparib and veliparib, respectively. This review describes the benefit of PARP inhibitors as maintenance therapy and discusses the efficacy according to breast cancer gene and homologous recombination status.

Aim: Poly(ADP-ribose) polymerase inhibitors (PARPIs) improved progression-free survival among patients with recurrent ovarian cancer. This meta-analysis examined the effectiveness of PARPIs as maintenance strategy for newly diagnosed patients with advanced high-grade ovarian cancer with or without mutations. Materials & methods: Using defined selection criteria, a literature search identified four eligible randomized clinical trials involving 2386 patients. Results: Compared with placebo maintenance, PARPIs achieved a 46% reduction in the risk of progression or death as compared with placebo (hazard ratio: 0.54; 95% CI: 0.39–0.73; p < 0.0001). That benefit was shown in all clinical subgroups: among those with BRCA mutation, with negative/unknown BRCA mutation, and in those with homologous recombination deficient tumors. Data about the effect on overall survival are still premature. Conclusion: In patients with newly diagnosed advanced ovarian cancer, PARPIs maintenance after standard therapy achieved a significant improvement in progression-free survival as compared with placebo, overall and in all subgroups.
