RESUMO
OBJECTIVE: The genitourinary syndrome of menopause (GSM) is often underdiagnosed and undertreated despite its significant impact on postmenopausal quality of life. We assessed the prevalence of GSM and associated symptoms in Greek perimenopausal/postmenopausal women attending gynecology clinics. METHODS: Four hundred and fifty women, aged 40-70 years (93.1% postmenopausal), attending three gynecology clinics at university hospitals completed a validated questionnaire and underwent pelvic examination. RESULTS: GSM was diagnosed in 87.6% of the women at the study visit, whereas only 16% of the overall sample had been previously diagnosed with the condition. Vaginal dryness (72.7%), vulvar burning sensation or itching (58.0%) and dyspareunia (52.7%) were the most prevalent symptoms. Pelvic signs consisted of vaginal dryness (89.1%), loss of vaginal rugae (80.6%) and vulvovaginal pallor (86.9%). However, only 31.3% of the participants had discussed genitourinary symptoms with their health-care professionals (HCPs). Regarding management, only 11.1% of women had prior experience with any form of therapy, and currently only 8.7% were receiving treatment. CONCLUSION: GSM is highly prevalent in this Greek perimenopausal/postmenopausal population. Nevertheless, the majority of women remain undiagnosed and untreated. Education for both women and HCPs regarding GSM will lead to improved diagnosis and better management of this syndrome.

The genital system remains one of the most common sites of carcinogenesis in women. Advances in surgery, radiation treatment, and chemotherapy have increased their efficacy and many patients survive for many years after their initial diagnosis. The eye is a rare site of metastasis from gynecological cancer due to its distant location from the genitalia. In this systematic review, we retrieved all case reports of patients with ocular metastasis from gynecological neoplasms. The demographic, clinical, and treatment characteristics were retrieved and analyzed. A total of 70 case reports were included. Forty-eight of these reports concerned patients with a known malignancy that recurred in the eye and in 22 patients' ocular symptomatology accompanied the initial diagnosis of the gynecologic malignancy. 73.9% of these patients exhibited concomitant metastasis to other organs. The mean disease-free interval was found at 25.7 months and mean survival time after the eye metastasis was 13.5 months. Refractory disease was identified as the most important risk factor associated with mortality. Because eye metastasis has such a dismal prognosis, all gynecologists who treat oncological patients should be highly suspicious for reported eye complaints.

Objectives: Sexual dysfunction and radiation cystitis are common adverse events following radiotherapy for gynecological cancer (GC). This study aims to assess the efficacy of intravaginal CO2 laser on GC survivors with dyspareunia following pelvic radiation and/or brachytherapy.Methods: This is the study protocol of a randomized double-blind placebo-controlled trial. All participants will receive five therapies (active or placebo) at monthly intervals. Outcomes will include a 10-cm visual analog scale measuring dyspareunia, vaginal dryness, and other symptom intensity, 3-day voiding diary, Day-to Day Impact of Vaginal Aging questionnaire, Female Sexual Function Index, European Organization for Research and Treatment of Cancer Quality of Life questionnaire cervical cancer module, Urogenital Distress Inventory short form, King's Health Questionnaire, International Consultation on Incontinence Questionnaire short form/female lower urinary tract symptoms, patient perception of improvement, sexual satisfaction of male partners, vaginal maturation value, and Vaginal Health Index. Differences between groups will be assessed at baseline and 1, 3, 6, 9, and 12 months following the five laser therapies.Results: As this is a study protocol, the study is ongoing with an expected end of recruitment and analysis date of 2021.Conclusion: Pelvic radiotherapy for GC increases the 5-year survival rate but with a negative impact on women's quality of life due to sexual dysfunction and radiation cystitis onset. With this study, CO2 laser therapy will be evaluated for the first time in GC survivors treated with radiotherapy. ClinicalTrials.gov registration number: NCT03714581.

Cancer prevalence is high, and of importance to cancer sufferers is the long term survival and normal activities resumption. Moreover, pregnancy is drawing interest for preserving ovarian reserves in post-chemotherapy affected women, especially of younger ages. The gonadotoxic effect of cancer treatment, involves mechanisms that are not fully understood, mainly due to the variety of molecular pathways triggered once therapeutic agents applied. Reported rates of premature ovarian failure after the treatment effect and the application of various treatment protocols, differ extensively due to the protocol itself but also due to the age of treated patients. Several options for preserving ovarian reserves are currently employed in the clinique, such as ovarian transposition, embryos cryopreservation and the use of gonadotropin-releasing hormone (GnRH) and its agonists/antagonists, but most of them are still under investigation. This paper reviews these methods and the molecular mechanisms that are possibly involved in the action of agents such as GnRH.

AIM: To report the authors' experience with dedicated pelvic magnetic resonance imaging (MRI) in young women with early-stage cervical cancer treated with abdominal radical trachelectomy (ART). MATERIALS AND METHODS: During a 5-year period, 21 patients, with biopsy-confirmed cervical carcinoma, International Federation of Gynaecology and Obstetrics (FIGO) stage ≤IB1, were considered for trachelectomy. All patients underwent pelvic MRI within 30 days prior to surgery. Tumour size, endocervical extension, extrauterine spread, and nodal status were noted. Postoperative MRI findings were reviewed in 16 patients. RESULTS: Nineteen of the 21 patients were treated with ART. In two patients, trachelectomy was aborted intraoperatively and radical hysterectomy was performed; preoperative MRI findings were consistent with surgicopathological examination in both patients. MRI correctly assessed tumour size in 18/21 patients, coming within 5 mm of the surgical specimen. Tumour size was underestimated in two cases because of circumferential growth (n = 1) or technical difficulties (n = 1). False-positive MRI result was due to post-biopsy inflammation (n = 1). MRI accurately identified absence of internal os involvement in 17/19 ART patients; false-positive MRI for internal os involvement were due to endocervical polyp (n = 1) and coexisting Nabothian cysts (n = 1). No trachelectomy patient had extrauterine disease or malignant nodes at MRI or final histology. Post-trachelectomy complications included hydrosalpinges (n = 3), lymphocysts (n = 2), isthmic stenosis (n = 1), and tumour relapse (n = 2). CONCLUSIONS: Dedicated pelvic MRI is helpful in assessing tumour size and endocervical extension in young women, candidates for ART. Hydrosalpinx may occur after ART and it may influence fertility potential.

Q fever is a disease of humans, caused by Coxiella burnetii, and a large range of animals can be infected. This paper presents a review of the epidemiology of Q fever in humans and farm animals between 1982 and 2010, using case studies from four European countries (Bulgaria, France, Germany and the Netherlands). The Netherlands had a large outbreak between 2007 and 2010, and the other countries a history of Q fever and Q fever research. Within all four countries, the serological prevalence of C. burnetii infection and reported incidence of Q fever varies broadly in both farm animals and humans. Proximity to farm animals and contact with infected animals or their birth products have been identified as the most important risk factors for human disease. Intrinsic farm factors, such as production systems and management, influence the number of outbreaks in an area. A number of disease control options have been used in these four countries, including measures to increase diagnostic accuracy and general awareness, and actions to reduce spillover (of infection from farm animals to humans) and human exposure. This study highlights gaps in knowledge, and future research needs.

AIMS: Dose-dense chemotherapy has proven its value in several cancer fields. The purpose of the present systematic review is to evaluate the impact of dose-dense chemotherapy on survival outcomes of epithelial ovarian cancer patients. MATERIALS AND METHODS: Medline, Scopus, the Cochrane Central Register of Controlled Trials CENTRAL, Google Scholar and Clinicaltrials.gov databases were searched for relevant articles. Effect sizes were calculated in Rstudio using the meta and metafor functions. A sensitivity analysis was carried out to evaluate the possibility of small study effects and P-hacking. The methodological quality of the included studies was assessed using Risk of Bias 2 (RoB2) and Risk of Bias in non-Randomized Trials (RoBINS) tools. RESULTS: Overall, 12 studies were included in the present systematic review, involving 4979 epithelial ovarian cancer patients. The risk of recurrence was substantially improved in patients receiving dose-dense chemotherapy (hazard ratio 0.82, 95% confidence interval 0.70, 0.96); however, the result of the meta-analysis may be attributed to the effect size of smaller studies as following adjustment for small study effects the outcome becomes non-significant (hazard ratio 0.91, 95% confidence interval 0.81, 1.02, P = 0.123). Overall survival rates were not improved by dose-dense chemotherapy (hazard ratio 0.79, 95% confidence interval 0.60, 1.04). Thirty-five types of adverse effect were identified following retrieval of data from the original studies. Dose-dense chemotherapy did not increase significantly the rates of severe adverse effects, although thrombosis, severe diarrhoea and severe nausea were more prevalent in this group of patients. CONCLUSION: Dose-dense chemotherapy is associated with comparable side-effects to those of standard chemotherapy; however, data related to survival outcomes are not positive; hence, its use outside the setting of clinical trials should be discouraged.

Background: The standard surgical treatment of endometrial carcinoma (EC) consisting of total hysterectomy with bilateral salpingo-oophorectomy drastically affects the quality of life of patients and creates a challenge for clinicians. Recent evidence-based guidelines of the European Society of Gynaecological Oncology (ESGO), the European SocieTy for Radiotherapy & Oncology (ESTRO) and the European Society of Pathology (ESP) provide comprehensive guidelines on all relevant issues of diagnosis and treatment in EC in a multidisciplinary setting. While also addressing work-up for fertility preservation treatments and the management and follow-up for fertility preservation, it was considered relevant to further extend the guidance on fertility sparing treatment. Objectives: To define recommendations for fertility-sparing treatment of patients with endometrial carcinoma. Materials and Methods: ESGO/ESHRE/ESGE nominated an international multidisciplinary development group consisting of practicing clinicians and researchers who have demonstrated leadership and expertise in the care and research of EC (11 experts across Europe). To ensure that the guidelines are evidence-based, the literature published since 2016, identified from a systematic search was reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the development group. The guidelines are thus based on the best available evidence and expert agreement. Prior to publication, the guidelines were reviewed by 95 independent international practitioners in cancer care delivery and patient representatives. Results: The multidisciplinary development group formulated 48 recommendations for fertility-sparing treatment of patients with endometrial carcinoma in four sections: patient selection, tumour clinicopathological characteristics, treatment and special issues. Conclusions: These recommendations provide guidance to professionals caring for women with endometrial carcinoma, including but not limited to professionals in the field of gynaecological oncology, onco-fertility, reproductive surgery, endoscopy, conservative surgery, and histopathology, and will help towards a holistic and multidisciplinary approach for this challenging clinical scenario. What is new?: A collaboration was set up between the ESGO, ESHRE and ESGE, aiming to develop clinically relevant and evidence-based guidelines focusing on key aspects of fertility-sparing treatment in order to improve the quality of care for women with endometrial carcinoma across Europe and worldwide.

RESUMO
BACKGROUND: Vascular endothelial growth factor action in tumour angiogenesis is well characterised; nevertheless, it functions as a key element in the promotion of the immune system's evasion by tumours. We sought to investigate the possible direct effect of VEGF on T-cell activation and through which type of VEGF receptor it exerts this effect on cells isolated from ovarian cancer patients' ascites. METHODS: T cells isolated from the ascites of ovarian cancer patients were cultured with anti-CD3 and IL-2, with or without VEGF for 14 days and the number of viable T cells was counted. Cytotoxic activity of cultured T cells and expression of VEGF receptor-2 (VEGFR-2), was assayed. RESULTS: The addition of VEGF in cultures significantly reduced the number and proliferation rate of T cells in a dose-dependent manner and CD3(+) T cells expressed VEGFR-2 on their surface upon activation. Experiments with specific anti-VEGFR-2 antibodies revealed that the direct suppressive effect of VEGF on T-cell proliferation is mediated by VEGFR-2. We also showed that VEGF significantly reduced the cytotoxic activity of T cells. CONCLUSION: Our study showed that ascites-derived T cells secrete VEGF and express VEGFR-2 upon activation. Vascular endothelial growth factor directly suppresses T-cell activation via VEGFR-2.

OBJECTIVE: To sonographically investigate cervical regeneration 6 months after large loop excision of the transformation zone (LLETZ) conisation for cervical intraepithelial neoplasia (CIN) pathology. DESIGN: Prospective observational study. SETTING: University Hospital setting. POPULATION: Women having LLETZ conisation for intraepithelial lesions in response to abnormal Papanicolaou smears or colposcopic findings. METHODS: Cervical dimensions were estimated before conisation and at 6 months with three-dimensional sonography and use of vocal™ software. Cone depth was measured using a ruler before fixation, and cone volume was measured using a volumetric tube and the fluid displacement technique. Cervical regeneration was sonographically estimated. MAIN OUTCOME MEASURES: Correlation of cervical volume regeneration with percentage of initial cervical volume excised and remaining cervical tissue immediately after conisation. RESULTS: A cohort of 112 women were initially recruited over a 2-year period and 73 women presented for ultrasound follow up at 6 months. Multivariate linear regression analysis showed that for women matched for age and initial cervical volume, if cervical volume excised was increased by 1% then regeneration of tissue deficit at the cervical crater was reduced by 1.37%. There also seemed to be a cutoff point suggesting that when >14% of initial cervical volume was excised, the tissue deficit at the cervical crater at 6 months was restored by <75% and there was >25% of remaining tissue deficit. CONCLUSIONS: Cervical regeneration at 6 months after excision is dependent on the percentage of initial cervical volume excised and on the remaining cervical tissue immediately after conisation. The greater the cone and the less cervical tissue remaining, the less the degree of cervical regeneration achieved.

OBJECTIVE: To evaluate the blood flow characteristics of the cervix in normal women and in women with cervical precancerous lesions or cervical cancer. METHODS: We studied 165 women with three-dimensional power Doppler ultrasound (3D-PDU), of whom 71 had cervical cancer, 61 had precancerous lesions and 33 were healthy controls. The cervix was manually traced in the stored volumes using 15° rotation steps and the following 3D-PDU indices were calculated: vascularization index (VI), flow index (FI) and vascularization flow index (VFI). These indices were compared among the study groups and were also correlated with features of the precancerous lesions group and cancer group. RESULTS: The three indices were all statistically significantly higher in the cervical cancer group and precancerous lesions group than in controls (P < 0.001). In addition, significantly higher values of all indices were found in the cervical cancer group than in the precancerous lesions group (P < 0.001). Further analysis according to patient characteristics in the cancer group showed that VI, FI and VFI were not significantly different in relation to grade, histology, presence of positive lymph nodes or lymphovascular space involvement (P > 0.05). However, VI was significantly higher in patients with Stages IIIB-IV cancer than in patients with less advanced disease (P = 0.045). In the cervical cancer group there was a significant positive correlation between 3D-PDU indices and cervical volume. CONCLUSION: 3D-PDU assessment of the cervix reveals significant differences in all indices studied between women with cervical precancerous lesions or cancer and healthy women. In women with cervical cancer, an advanced stage is associated with higher VI, but 3D-PDU indices are not related to other pathological characteristics.

Therapy for endometrial, ovarian and cervical cancer in young women can cause sudden onset of intense menopausal symptoms, such as hot flushes, emotional disorders and sexual dysfunction. In order to overcome these unpleasant and sometimes severe symptoms, hormone replacement therapy (HRT) has proven to be very effective. However, its safety remains controversial. We reviewed English literature and examined whether administration of HRT in this specific population is related with more recurrences and worse prognosis. Current scientific data, comprising mainly retrospective studies, suggest that recurrence rates and survival are comparable between HRT users and non-users. However, large randomised trials are missing and definitive conclusions cannot be drawn. Gynaecological cancer survivors using HRT, although they seem to have little if any risk for recurrence, should be correctly informed about the lack of strong evidence.

OBJECTIVE: Early-stage epithelial ovarian cancer represents a prognostically heterogenous group. We studied prognostic factors in patients treated with adjuvant paclitaxel/carboplatin chemotherapy. METHODS: Data was extracted from 147 patients with FIGO stage IA/IB, grade 2/3 or stage IC/IIA (any grade) who underwent primary surgery followed by paclitaxel/carboplatin chemotherapy. RESULTS: Median follow-up was 88 months. Ten-year relapse-free (RFS) and disease-specific survival (DSS) were: 81% (95% confidence interval [CI]: 73-89) and 81% (95% CI: 73-89). On multivariate analysis, non serous histology was associated with reduced risk for RFS (0.294, 95% CI: 0.112-0.577, p=0.001) and DSS (0.194, 95% CI: 0.075-0.504, p=0.001), while high-risk category (stage IC/IIA and grade 2/3) with increased risk for RFS (3.989, 95% CI: 1.189-13.389, p=0.009) and DSS (3.989, 95% CI: 1.064-16.386, p=0.038). The combination of histology and grade identified 3 groups with distinctly different 10-year RFS and DSS rates (p<0.001): grade 1 (100% and 100%), non-serous grade 2/3 (83% and 86%) and serous grade 2/3 (60% and 60%). CONCLUSIONS: Serous histology is an adverse prognostic factor in early-stage ovarian cancer treated with adjuvant paclitaxel/carboplatin. Risk stratification according to histology and grade is a useful discriminator of prognosis and can be used in the design of future studies.

BACKGROUND: Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is the recommended approach in patients with advanced epithelial ovarian cancer (EOC). However, most patients eventually relapse despite the initial high response rate to chemotherapy. Neutrophil-to-lymphocyte ratio is a well-known biomarker that reflects severe inflammation, critical illness, and mortality in various diseases. Chemotherapy response score (CRS) and neutrophil-to-lymphocyte ratio (NLR) have been identified as potential biomarkers of platinum resistance and disease prognosis. We retrospectively evaluated 132 patients with stage IIIc or IV ovarian/fallopian tube/primary peritoneal cancer who had received NACT followed by IDS from 01/01/2003 to 31/12/2018. CRS was assessed on omental specimens collected from IDS according to ICCR guidelines. RESULTS: Median age was 64.57 years (SD: 9.72; range 39.2-87.1). Most ovarian tumors were serous epithelial (90.9%; 120/132). An elevated NLR (defined as > 3) was observed in 72% (95/132) of patients in contrast with 28% (37/132) of patients characterized by low NLR status. Median PFS (mPFS) and median overall survival (mOS) were 13.05 months (95% CI: 11.42-14.67)) and 34.69 months (95% CI: 23.26-46.12) respectively. In univariate analysis, CRS3 score was significantly associated with prolonged mPFS (CRS1/2: 12.79 months vs CRS3: 17.7 months; P = 0.008). CRS score was not associated with mOS (P = 0.876). High NLR was not significantly associated with mPFS (P = 0.128), however it was significantly associated with poor mOS (P = 0.012). In multivariate analysis, only performance of surgery maintained its statistical significance with both PFS (P = 0.001) and OS (P = 0.008). CONCLUSION: NLR could serve as a useful predictor of OS but not PFS in ovarian cancer patients receiving NACT. In accordance with our previous study, CRS score at omentum was found to be associated with PFS but not OS in ovarian cancer patients treated with NACT and IDS.
Biomarkers that would predict response to neoadjuvant chemotherapy in advanced ovarian cancer patients are eagerly needed:⢠Neutrophil to Lymphocyte Ratio (NLR) is an indicator of systemic inflammatory response to the malignancy.⢠NLR was evaluated in 132 patients undergoing Neoadjuvant Chemotherapy for advanced ovarian cancer.⢠Elevated NLR was associated with worse prognosis.⢠No association between NLR and response to chemotherapy was noted.

Comparative genomic analysis of a wild-type strain of the ovine pathogen Chlamydia abortus and its nitrosoguanidine-induced, temperature-sensitive, virulence-attenuated live vaccine derivative identified 22 single nucleotide polymorphisms unique to the mutant, including nine nonsynonymous mutations, one leading to a truncation of pmpG, which encodes a polymorphic membrane protein, and two intergenic mutations potentially affecting promoter sequences. Other nonsynonymous mutations mapped to a pmpG pseudogene and to predicted coding sequences encoding a putative lipoprotein, a sigma-54-dependent response regulator, a PhoH-like protein, a putative export protein, two tRNA synthetases, and a putative serine hydroxymethyltransferase. One of the intergenic mutations putatively affects transcription of two divergent genes encoding pyruvate kinase and a putative SOS response nuclease, respectively. These observations suggest that the temperature-sensitive phenotype and associated virulence attenuation of the vaccine strain result from disrupted metabolic activity due to altered pyruvate kinase expression and/or alteration in the function of one or more membrane proteins, most notably PmpG and a putative lipoprotein.

Few data are available on the prevalence and relevance of chlamydiae in wild mammals, and even fewer studies have been conducted to determine the prevalence of Chlamydophila abortus in wildlife hosts, most probably due to the absence of suitable species-specific serological assays for testing sera from wild animals. In light of this, we have developed two in-house blocking-ELISA tests for detection of antibodies against Chlamydiaceae and C. abortus in wild ungulates, and analyzed the relationship between geographical and biological factors and the prevalence of antibodies against Chlamydiaceae and C. abortus in 434 wild ungulates from Spain, including sera from European wild boar, Red deer, Fallow deer, Roe deer, Mouflon, Barbary sheep, Southern chamois, and Iberian ibex. Serology revealed that 41.7+/-4% of the sera were positive for the b-ELISA-LPS (Chlamydiaceae-specific) and 18.9+/-3% for the b-ELISA-rPOMP (C. abortus-specific). Antibodies against Chlamydiaceae lipopolysaccharide (LPS) were detected in sera from all eight ungulate species, the prevalence ranging from 23 to 60%. Iberian ibex was the only wild ungulate not showing seropositivity to the C. abortus specific polymorphic outer membrane protein (POMP). The prevalence of anti-POMP antibodies in the other seven wild ungulate species ranged from 7 to 40%. While significant seroprevalence differences were detected among species and among sampling regions, no effect of age and sex was observed. The high prevalence levels found should be considered with regards to livestock and human health, and warrant further research.

BACKGROUND: The management of ovarian cancer during pregnancy represents a major challenge and requires close multidisciplinary team approach. CASE: A 35-year-old pregnant woman with a yolk sac tumor underwent left salpingo-oophorectomy at 25 weeks of gestation. Chemotherapy was deferred to the end of the pregnancy owing to concerns for potential fetal risks. Alpha-feto protein level was used to monitor the underlying disease activity. The patient underwent exploratory laparotomy with cesarean section followed by total hysterectomy, omentectomy, right salpingooophorectomy, pelvic, and para-aortic lymphadenectomies at 32 weeks of gestation. She received four postoperative courses of chemotherapy (cisplatin, etoposide, and peplomycin). Currently, mother and child are doing well 6 months after the last chemotherapy cycle. CONCLUSION: In a case of yolk sac tumor in the second trimester of pregnancy, radical surgery combined with elective caesarian section followed by chemotherapy could achieve remission and rescue of fetus. However, the treatment needs to be individualized as there is lack of evidence.

We report a case of a 24-year-old female who underwent laparoscopy for a presumed benign ovarian mass. Frozen sections at laparoscopy initially revealed a borderline papillary serous ovarian tumour. Final histology showed an invasive papillary serous ovarian tumor (grade 1). Subsequent staging laparotomy conducted 13 days later revealed peritoneal implantations thus upgrading the initially thought Stage Ia papillary serous ovarian tumour at laparoscopy to Stage IIc. The patient after laparotomy had an uneventful postoperative course and received six cycles of chemotherapy based on taxol and carboplatin. A short review of the literature is also presented, concerning the factors which affect the patient's prognosis in cases of unexpected ovarian malignancy found during laparoscopy that are treated with subsequent staging laparotomy.

PURPOSE OF INVESTIGATION: Primary fallopian tube carcinoma (PFTC) is a rare malignancy with only few data existing on the impact of prognostic factors. METHODS: We retrospectively analyzed 26 patients. Tissue blocks were reviewed and sections were stained for vascular endothelial growth factor (VEGF), matrix metalloproteinases 2 and 9 (MMP-2, MMP-9), tissue inhibitors of metalloproteinases 1 and 2 (TIMP-1, TIMP-2), c-erbB-2, estrogen (ER), and progesterone receptors (PgR). RESULTS: Reactivity for VEGF, ER, PgR, MMP-2, MMP-9, TIMP-1, TIMP-2 and c-erbB-2 was observed in 85%, 46%, 27%, 11.5%, 58%, 0%, 23% and 8% of specimens, respectively. None of the markers studied displayed prognostic significance. Regarding clinical prognostic factors, the hazard ratio (HR) for progression and death for patients with tumor residuum > 2 cm was 5.24 (p < 0.01) and 11.19 (p < 0.005), respectively. Patients with advanced stage disease had a HR of 12.55 (p < 0.05) for progression, while the HR for death was not found to be statistically significant. CONCLUSION: None of the biomarkers studied seems to influence survival. Early-stage disease and optimal debulking are associated with improved outcome.
