Prognosis Following Surgery for Recurrent Ovarian Cancer and Diagnostic Criteria Predictive of Cytoreduction Success: A Systematic Review and Meta-Analysis.

For women achieving clinical remission after the completion of initial treatment for epithelial ovarian cancer, 80% with advanced-stage disease will develop recurrence. However, the standard treatment of women with recurrent platinum-sensitive diseases remains poorly defined. Secondary (SCS), tertiary (TCS) or quaternary (QCS) cytoreduction surgery for recurrence has been suggested to be associated with increased overall survival (OS). We searched five databases for studies reporting death rate, OS, cytoreduction rates, post-operative morbidity/mortality and diagnostic models predicting complete cytoreduction in a platinum-sensitive disease recurrence setting. Death rates calculated from raw data were pooled based on a random-effects model. Meta-regression/linear regression was performed to explore the role of complete or optimal cytoreduction as a moderator. Pooled death rates were 45%, 51%, 66% for SCS, TCS and QCS, respectively. Median OS for optimal cytoreduction ranged from 16-91, 24-99 and 39-135 months for SCS, TCS and QCS, respectively. Every 10% increase in complete cytoreduction rates at SCS corresponds to a 7% increase in median OS. Complete cytoreduction rates ranged from 9-100%, 35-90% and 33-100% for SCS, TCS and QCS, respectively. Major post-operative thirty-day morbidity was reported to range from 0-47%, 13-33% and 15-29% for SCS, TCS and QCS, respectively. Thirty-day post-operative mortality was 0-6%, 0-3% and 0-2% for SCS, TCS and QCS, respectively. There were two externally validated diagnostic models predicting complete cytoreduction at SCS, but none for TCS and QCS. In conclusion, our data confirm that maximal effort higher order cytoreductive surgery resulting in complete cytoreduction can improve survival.

Impact of minimally invasive surgery on surgical outcomes for obese women with endometrial cancer following robotic surgery introduction; a single centre study.

BACKGROUND: The aim was to assess the surgical outcomes in obese women with endometrial cancer following robotic surgery introduction in a London tertiary gynaecological cancer unit. METHODS: Data was prospectively collected for 281 women undergoing endometrial cancer surgery in 2016, 2018 and 2019 (robotic surgery was introduced in November 2017). RESULTS: The proportion of obese and morbidly obese patients undergoing minimally invasive surgery (MIS) significantly increased following robotic surgery introduction from 43.8% to 69.6% (p < 0.001). Overall robotic surgery operating time was not affected by higher body mass index (r = 0.177, 95% CI -0.068-0.402). There was no difference in the length of stay or in the frequency and severity of complication rates between obese, morbidly obese and non-obese populations undergoing MIS. CONCLUSION: Robotic surgery led to a significant rise in MIS and improved surgical outcomes for obese and morbidly obese women with endometrial cancer within 12 months of its introduction.

Patient outcomes following interval and delayed cytoreductive surgery in advanced ovarian cancer: protocol for a multicenter, international, cohort study (Global Gynaecological Oncology Surgical Outcomes Collaborative).

BACKGROUND: The Global Gynecological Oncology Surgical Outcomes Collaborative (GO SOAR) has developed a network of gynecological oncology surgeons, surgical departments, and other interested parties that have the long-term ability to collaborate on outcome studies. Presented is the protocol for the GO SOAR2 study. PRIMARY OBJECTIVES: To compare survival following interval and delayed cytoreductive surgery, between delayed cytoreductive surgery and no surgery (chemotherapy alone); and international variations in access to cytoreductive surgery for women with stage III-IV epithelial ovarian cancer. STUDY HYPOTHESES: There is no difference in survival following interval and delayed cytoreductive surgery; there is poorer survival with no surgery compared with delayed cytoreductive surgery; and there are international disparities in prevalent practice and access to cytoreductive surgery in women with stage III-IV epithelial ovarian cancer. TRIAL DESIGN: International, multicenter, mixed-methods cohort study. Participating centers, will review medical charts/electronic records of patients who had been consecutively diagnosed with stage III-IV ovarian cancer between January 1, 2006 and December 31, 2021. Qualitative interviews will be conducted to identify factors determining international variations in prevalent practice and access to cytoreductive surgery. MAJOR INCLUSION/EXCLUSION CRITERIA: Inclusion criteria include women with stage III-IV epithelial ovarian cancer, undergoing interval (after 3-4 cycles of chemotherapy) or delayed (≥5 cycles of chemotherapy) cytoreductive surgeries or no cytoreductive surgery (≥5 cycles of chemotherapy alone). PRIMARY ENDPOINTS: Overall survival (defined from date of diagnosis to date of death); progression-free survival (defined from date of diagnosis to date of first recurrence); facilitator/barriers to prevalent practice and access to cytoreductive surgery. SAMPLE SIZE: In order to determine whether there is a difference in survival following interval and delayed cytoreductive surgery and no surgery, data will be abstracted from 1000 patients. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: It is estimated that recruitment will be completed by 2023, and results published by 2024. TRIAL REGISTRATION: NCT05523804.

Concise Reporting of Benign Endometrial Biopsies is an Acceptable Alternative to Descriptive Reporting.

In the United Kingdom, endometrial biopsy reports traditionally consist of a morphologic description followed by a conclusion. Recently published consensus guidelines for reporting benign endometrial biopsies advocate the use of standardized terminology. In this project we aimed to assess the acceptability and benefits of this simplified "diagnosis only" format for reporting non-neoplastic endometrial biopsies. Two consultants reported consecutive endometrial biopsies using 1 of 3 possible formats: (i) diagnosis only, (ii) diagnosis plus an accompanying comment, and (iii) the traditional descriptive format. Service users were asked to provide feedback on this approach via an anonymized online survey. The reproducibility of this system was assessed on a set of 53 endometrial biopsies among consultants and senior histopathology trainees. Of 370 consecutive benign endometrial biopsies, 245 (66%) were reported as diagnosis only, 101 (27%) as diagnosis plus a brief comment, and 24 (7%) as diagnosis following a morphologic description. Of the 43 survey respondents (28 gynecologists, 11 pathologists, and 4 clinical nurse specialists), 40 (93%) preferred a diagnosis only, with 3 (7%) being against/uncertain about a diagnosis only report. Among 3 histopathology consultants and 4 senior trainees there was majority agreement on the reporting format in 53/53 (100%) and 52/53 (98%) biopsies. In summary, we found that reporting benign specimens within standardized, well-understood diagnostic categories is an acceptable alternative to traditional descriptive reporting, with the latter reserved for the minority of cases that do not fit into specific categories. This revised approach has the potential to improve reporting uniformity and reproducibility.

Implementation of Multigene Germline and Parallel Somatic Genetic Testing in Epithelial Ovarian Cancer: SIGNPOST Study.

We present findings of a cancer multidisciplinary-team (MDT) coordinated mainstreaming pathway of unselected 5-panel germline BRCA1/BRCA2/RAD51C/RAD51D/BRIP1 and parallel somatic BRCA1/BRCA2 testing in all women with epithelial-OC and highlight the discordance between germline and somatic testing strategies across two cancer centres. Patients were counselled and consented by a cancer MDT member. The uptake of parallel multi-gene germline and somatic testing was 97.7%. Counselling by clinical-nurse-specialist more frequently needed >1 consultation (53.6% (30/56)) compared to a medical (15.0% (21/137)) or surgical oncologist (15.3% (17/110)) (p < 0.001). The median age was 54 (IQR = 51-62) years in germline pathogenic-variant (PV) versus 61 (IQR = 51-71) in BRCA wild-type (p = 0.001). There was no significant difference in distribution of PVs by ethnicity, stage, surgery timing or resection status. A total of 15.5% germline and 7.8% somatic BRCA1/BRCA2 PVs were identified. A total of 2.3% patients had RAD51C/RAD51D/BRIP1 PVs. A total of 11% germline PVs were large-genomic-rearrangements and missed by somatic testing. A total of 20% germline PVs are missed by somatic first BRCA-testing approach and 55.6% germline PVs missed by family history ascertainment. The somatic testing failure rate is higher (23%) for patients undergoing diagnostic biopsies. Our findings favour a prospective parallel somatic and germline panel testing approach as a clinically efficient strategy to maximise variant identification. UK Genomics test-directory criteria should be expanded to include a panel of OC genes.

Histopathologic response to neoadjuvant chemotherapy as a prognostic biomarker in tubo-ovarian high-grade serous carcinoma: updated Chemotherapy Response Score (CRS) results.

OBJECTIVE: The Chemotherapy Response Scoring (CRS) system was developed to enable reproducible reporting of histologic tumor response in interval debulking specimens following neoadjuvant chemotherapy in advanced stage tubo-ovarian high-grade serous carcinoma. This prognostic biomarker has been included in ovarian cancer pathology reporting guidelines (International Collaboration on Cancer Reporting, College of American Pathologists) and in the upcoming European Society for Medical Oncology-European Society of Gynaecological Oncology (ESMO-ESGO) guidelines for ovarian cancer management. We present follow-up data on the CRS validation initiatives and suggest research with novel therapeutic agents incorporating this biomarker. METHODS: The cohort on whom CRS was originally developed was analyzed after an extended follow-up of an additional 36 months. The CRS histopathologic scoring system was applied to omental sections obtained at interval surgery from all 80 patients. Progression-free and overall survival were re-calculated. RESULTS: After a median follow-up of 4.3 years the CRS score predicted progression-free survival with an HR of 0.39 (95% CI 0.21 to 0.70), p = 0.002 adjusted for age, stage, and debulking status (median 1.08 vs 2.27 years for CRS1/2 vs CRS3). CRS was also predictive of overall survival with an HR of 0.17 (95% CI 0.07 to 0.44), p = 0.0002 adjusted for age, stage, and debulking status (median 2.55 vs 5.47 years for CRS1/2 vs CRS3). CONCLUSION: CRS3 is a reproducible prognostic biomarker for improved progression-free and overall survival in stage 3C or 4 tubo-ovarian high-grade serous carcinoma after neoadjuvant chemotherapy. The score, obtained at interval debulking surgery, can help facilitate research and biomarker driven first-line treatment of patients with advanced ovarian cancer.

Persistence of fimbrial tissue on the ovarian surface after salpingectomy.

BACKGROUND: Salpingectomy is recommended as a risk-reducing strategy for epithelial tubo-ovarian cancer. The gold standard procedure is complete tubal excision. OBJECTIVE: The purpose of this study was to assess the presence of residual fimbrial/tubal tissue on ovarian surfaces after salpingectomy. STUDY DESIGN: Prospective analysis of patients who underwent salpingo-oophorectomy with or without hysterectomy for benign indications, early cervical cancer, or low-risk endometrial cancer at a UK National Health Service Trust. Salpingectomy with or without hysterectomy was performed initially, followed by oophorectomy within the same operation. Separately retrieved tubes and ovaries were sectioned serially and examined completely histologically. The main outcome measure was histologically identified fimbrial/ tubal tissue on ovarian surface. Chi-square/Fisher's exact tests were used to evaluate categoric variables. RESULTS: Twenty-five consecutive cases (mean age, 54.8 ± 5.0 years) that comprised 41 adnexae (unilateral, 9; bilateral, 16) were analyzed. Seventeen (68.0%), 5 (20.0%), and 3 (12.0%) procedures were performed by consultant gynecologists, subspecialty/specialist trainees, and consultant gynecologic oncologists, respectively. Twelve of 25 procedures (48.0%) were laparoscopic, and 13 of 25 procedures (52.0%) involved laparotomy. Four of 25 patients (16.0%; 95% confidence interval, 4.5-36.1%) or 4 of 41 adnexae (9.8%; 95% confidence interval, 2.7-23.1%) showed residual microscopic fimbrial tissue on the ovarian surface. Tubes/ovaries were free of adhesions in 23 cases. Two cases had dense adnexal adhesions, but neither had residual fimbrial tissue on the ovary. Residual fimbrial tissue was not associated significantly with surgical route or experience (consultant, 3/20 [15%]; trainee, 1/5 [20%]; P=1.0). CONCLUSION: Residual fimbrial tissue remains on the ovary after salpingectomy in a significant proportion of cases and could impact the level of risk-reduction that is obtained.

A comparison of p53 and WT1 immunohistochemical expression patterns in tubo-ovarian high-grade serous carcinoma before and after neoadjuvant chemotherapy.

AIMS: The treatment of patients with tubo-ovarian high-grade serous carcinoma (HGSC) is increasingly based on diagnosis on small biopsy samples, and the first surgical sample is often taken post-chemotherapy. p53 and WT1 are important diagnostic markers for HGSC. The effect of neoadjuvant chemotherapy on p53 and WT1 expression has not been widely studied. We aimed to compare p53 and WT1 expression in paired pre-chemotherapy and post-chemotherapy samples of HGSC. METHODS AND RESULTS: Immunohistochemistry (IHC) was carried out for p53 and WT1 on paired omental HGSC samples pre-chemotherapy and post-chemotherapy. p53 IHC was recorded as normal (wild-type) or abnormal (mutation-type), and was further classified as overexpression, complete absence, or cytoplasmic. WT1 IHC was classified as positive or negative. A subset of cases were further assessed for the extent of nuclear immunoreactivity of WT1 by use of the H-score. Fifty-seven paired samples were stained with p53. Fifty-six of 57 (98%) cases showed mutation-type p53 staining. Pre-chemotherapy and post-chemotherapy IHC results were concordant in 55 of 57 (96%) cases. For WT1, pre-chemotherapy and post-chemotherapy IHC results were concordant in 56 of 58 (97%) cases. In 23 paired WT1 cases, the mean post-treatment H-score decreased from 227 [range 20-298, standard deviation (SD) 64] to 151 (range 0-288, SD 78) (P = 0.0008). CONCLUSIONS: Immunohistochemical expression of p53 (abnormal/mutation-type pattern) and WT1 in HGSC is almost universal and is largely concordant before and after chemotherapy. This finding underscores the reliability of these diagnostic markers in small samples and in surgical samples following neoadjuvant chemotherapy, with very few exceptions. A novel finding was the significant diminution in intensity of WT1 staining following chemotherapy.

Neoadjuvant Chemotherapy Modulates the Immune Microenvironment in Metastases of Tubo-Ovarian High-Grade Serous Carcinoma.

PURPOSE: The purpose of this study was to assess the effect of neoadjuvant chemotherapy (NACT) on immune activation in stage IIIC/IV tubo-ovarian high-grade serous carcinoma (HGSC), and its relationship to treatment response. EXPERIMENTAL DESIGN: We obtained pre- and posttreatment omental biopsies and blood samples from a total of 54 patients undergoing platinum-based NACT and 6 patients undergoing primary debulking surgery. We measured T-cell density and phenotype, immune activation, and markers of cancer-related inflammation using IHC, flow cytometry, electrochemiluminescence assays, and RNA sequencing and related our findings to the histopathologic treatment response. RESULTS: There was evidence of T-cell activation in omental biopsies after NACT: CD4(+) T cells showed enhanced IFNγ production and antitumor Th1 gene signatures were increased. T-cell activation was more pronounced with good response to NACT. The CD8(+) T-cell and CD45RO(+) memory cell density in the tumor microenvironment was unchanged after NACT but biopsies showing a good therapeutic response had significantly fewer FoxP3(+) T regulatory (Treg) cells. This finding was supported by a reduction in a Treg cell gene signature in post- versus pre-NACT samples that was more pronounced in good responders. Plasma levels of proinflammatory cytokines decreased in all patients after NACT. However, a high proportion of T cells in biopsies expressed immune checkpoint molecules PD-1 and CTLA4, and PD-L1 levels were significantly increased after NACT. CONCLUSIONS: NACT may enhance host immune response but this effect is tempered by high/increased levels of PD-1, CTLA4, and PD-L1. Sequential chemoimmunotherapy may improve disease control in advanced HGSC. Clin Cancer Res; 22(12); 3025-36. ©2016 AACR.

Chemotherapy Response Score: Development and Validation of a System to Quantify Histopathologic Response to Neoadjuvant Chemotherapy in Tubo-Ovarian High-Grade Serous Carcinoma.

PURPOSE: To develop and validate a histopathologic scoring system for measuring response to neoadjuvant chemotherapy in interval debulking surgery specimens of stage IIIC to IV tubo-ovarian high-grade serous carcinoma. PATIENTS AND METHODS: A six-tier histopathologic scoring system was proposed and applied to a test cohort (TC) of 62 patients treated with neoadjuvant chemotherapy and interval debulking surgery. Adnexal and omental sections were independently scored by three pathologists. On the basis of TC results, a three-tier chemotherapy response score (CRS) system was developed and applied to an independent validation cohort of 71 patients. RESULTS: The initial system showed moderate interobserver reproducibility and prognostic stratification of TC patients when applied to the omentum but not to the adnexa. Condensed to a three-tier score, the system was highly reproducible (kappa, 0.75). When adjusted for age, stage, and debulking status, the score predicted progression-free survival (PFS; score 2 v 3; median PFS, 11.3 v 32.1 months; adjusted hazard ratio, 6.13; 95% CI, 2.13 to 17.68; P < .001). The three-tier CRS system applied to omental samples from the validation cohort showed high reproducibility (kappa, 0.67) and predicted PFS (CRS 1 and 2 v 3: median, 12 v 18 months; adjusted hazard ratio, 3.60; 95% CI, 1.69 to 7.66; P < .001). CRS 3 also predicted sensitivity to first-line platinum therapy (94.3% negative predictive value for progression < 6 months). A Web site was established to train pathologists to use the CRS system. CONCLUSION: The CRS system is reproducible and shows prognostic significance for high-grade serous carcinoma. Implementation in international pathology reporting has been proposed by the International Collaboration on Cancer Reporting, and the system could potentially have an impact on patient care and research.

Surgical treatment of stage IA2 cervical cancer.

BACKGROUND: Cervical cancer is the second most common cancer among women up to 65 years of age and is the most frequent cause of death from gynaecological cancers worldwide. Women with International Federation of Gynecology and Obstetrics (FIGO) stage IA2 cervical cancer have measured stromal invasion (when the cancer breaks through the basement membrane of the epithelium) of greater than 3 mm and no greater than 5 mm in depth with a horizontal surface extension of no more than 7 mm. For stage IA2 disease, radical hysterectomy with pelvic lymphadenectomy or radiotherapy is the standard treatment. In order to avoid complications of more radical surgical methods, less invasive options, such as simple hysterectomy, simple trachelectomy or conisation, with or without pelvic lymphadenectomy, may be feasible for stage IA2 disease, considering the relative low risk of local or distant metastatic disease. The evidence for less radical tumour excision and for the role of systematic lymphadenectomy in stage IA2 cervical cancer is not clear. OBJECTIVES: To evaluate the effectiveness and safety of less radical surgery in stage IA2 cervical cancer. SEARCH METHODS: We searched the Cochrane Gynaecological Cancer Group trials register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE up to September 2013. We also searched registers of clinical trials and abstracts of scientific meetings. SELECTION CRITERIA: We searched for randomised controlled trials (RCTs) that compared surgical techniques in women with stage IA2 cervical cancer. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. We found no trials and, therefore, no data were analysed. MAIN RESULTS: The search strategy identified 982 unique references, which were all excluded on the basis of title and abstract because it was clear that they did not meet the inclusion criteria. We identified one relevant large ongoing trial, so it is anticipated that we will be able to add this evidence to this review in the future. AUTHORS' CONCLUSIONS: We found no evidence to inform decisions about different surgical techniques in women with stage IA2 cervical cancer. In the future, the results of one large ongoing RCT should allow comparison of different types of surgery.

Women's experiences after a radical vaginal trachelectomy for early stage cervical cancer. A descriptive phenomenological study.

PURPOSE: This paper reports on a phenomenological study of women's experiences 1-10 years following a radical vaginal trachelectomy and describes the impact on health, sexuality, fertility and perceived supportive care needs. METHOD AND SAMPLE: Qualitative telephone interviews employing a descriptive phenomenological approach were conducted using a purposive sample of 12 women. KEY RESULTS: Several felt their cancer experience was positive; bringing them closer to family and changed their outlook on life. A few experienced delayed psychological reactions and/or fears of recurrence. Many experienced isolation and the desire to contact others with similar experiences. Women recovered well but a few experienced fears/concerns about lymphoedema and intermenstrual bleeding. Sexual function was not a long-term issue for most. Some that could feel the cerclage (stitch) during intercourse, developed techniques to reduce this. Single women felt vulnerable in new relationships. Pregnancy was an anxious time, especially for those that experienced a miscarriage or pre-term birth. Sources of support included the clinical nurse specialist, family/friends, surgical consultant, online patient forums and a support group. Women needed more information on trachelectomy statistics, pregnancy care recommendations as well as access to counselling, peer support, being seen by the same person and increased public awareness. CONCLUSIONS: This study has provided an interesting and detailed insight into women's experiences in the years following a trachelectomy, with results that have important considerations for practice such as provision of statistical information; counselling; peer support; consistent pregnancy recommendations; increased public awareness and increased identification and management or prevention of long-term physical effects.

Primary chemotherapy for inoperable ovarian, fallopian tube, or primary peritoneal cancer with or without delayed debulking surgery.

OBJECTIVE: To describe the outcome of primary chemotherapy for women with advanced-stage epithelial ovarian or primary peritoneal cancer and delayed surgery when optimal debulking surgery cannot be achieved at diagnosis. METHODS: Between 1998 and 2006, we retrospectively reviewed the overall survival and examined prognostic markers in consecutive patients who were not suitable for initial radical surgery because of the extent of disease and/or poor performance status. They were treated with a policy of primary platinum-based chemotherapy, followed whenever possible in responding patients by debulking surgery. RESULTS: A total of 171 patients received least one cycle of chemotherapy. Eighty-six patients proceeded to surgery and 53 (31% of 171 and 62% of 86) had optimal (<1 cm) residual disease. Eighty-five patients did not undergo surgery because they remained unfit or had not responded sufficiently to chemotherapy. The median overall survival was 18.7 months (95% confidence interval [CI], 16.5-24.2). The median OS in the surgical group for optimal and suboptimal surgery was 40.8 (95% CI, 32.5-50.0) and 22.5 (95% CI, 17.7-37.1) months (P = 0.005). On multivariate analysis, interval surgery and optimal surgery were the only independent prognostic factors (hazard ratios, 0.45 and 0.43, respectively; P = 0.009). In the nonsurgical group, CA125 response was an independent prognostic factor (hazard ratio, 0.34; P = 0.001) with an OS of 21.7 months (95% CI, 14.0-35.4) in women with a normal CA125 after treatment compared with 6.7 (95% CI, 4.5-7.8) months. CONCLUSIONS: In one third of the women, the tumor was optimally debulked after primary chemotherapy and their median survival was 40.8 months. Suboptimal debulking surgery after primary chemotherapy did not result in a better survival than that achieved after a chemotherapy response alone, suggesting that surgery may be avoided when imaging after chemotherapy demonstrates residual disease that cannot be optimally debulked.

Perforation of a malignant ovarian tumor into the recto-sigmoid colon.

Ovarian cancer often presents at an advanced stage, but tends to be an intra-peritoneal disease that respects peritoneal planes. Thus, colo-rectal perforation of the tumor is an extremely rare presentation. The surgical treatment of malignant colo-ovarian fistula should include complete cyto-reduction at the same time as the treatment of the fistula. However, prognosis remains poor, because of the advanced stage of neoplasia. We report the case of a patient with an ovarian malignant tumor perforating into the recto-sigmoid colon. CT scan was the cornerstone of the radiological diagnosis. We managed to perform a complete cyto-reduction, including an en-bloc resection of the uterus, the mass, adnexa and recto-sigmoid with removal of the associated pelvic abscess.

Cervical lymphadenopathy - an unusual presentation of carcinoma of the cervix: a case report.

INTRODUCTION: The clinical presentation of carcinoma of the cervix as cervical lymphadenopathy has not been described before. We report a case of this unusual manifestation of cervical cancer. CASE PRESENTATION: A 51-year-old woman presented to our Head and Neck department with cervical lymphadenopathy. A positron emission tomography scan revealed the primary tumour to be in the cervix and a cervical biopsy confirmed carcinoma of the cervix. CONCLUSION: Recurrences of carcinoma of the cervix presenting as lymphadenopathy have been described before but this is the first time a clinical presentation of carcinoma of the cervix as cervical lymphadenopathy has been described. Although metastasis from the cervix to the cervical lymph nodes is rare, this can be explained by outlining the drainage of the lymphatic system from the cervix.

Cytoreductive surgery in ovarian cancer.

As the overall prognosis for patients with ovarian cancer is poor, the management of this condition should be restricted to expert multi-disciplinary teams in gynaecological oncology. Apparent early stage ovarian cancer requires accurate and complete staging so that potential sites for metastases are not missed. Omitting adequate staging may have significant consequences including a negative impact on survival rates in young patients. The challenge with advanced ovarian cancer is to obtain a detailed appreciation of the extent of disease. This information allows treatment with primary chemotherapy if the cancer is considered to be inoperable and/or the general condition of the patient renders her unfit for appropriate surgery. Available data would suggest that a 5-year survival rate of 50% is only possible for those patients who have had complete cytoreduction of all tumour. Therefore, the best surgical option for patients with advanced ovarian cancer is a 'complete' primary surgical procedure that achieves complete clearance of the abdominal cavity rather than 'optimal' surgery that leaves tumour nodules up to 1 cm in diameter in situ in the patient.
