Abstract
PURPOSE Intrauterine levonorgestrel (LNG-IUD) is used to treat patients with endometrial adenocarcinoma (EAC) and endometrial hyperplasia with atypia (EHA) but limited evidence is available on its effectiveness. The study determined the extent to which LNG-IUD with or without metformin (M) or weight loss (WL) achieves a pathological complete response (pCR) in patients with EAC or EHA. PATIENTS AND METHODS This phase II randomized controlled clinical trial enrolled patients with histologically confirmed, clinically stage 1 FIGO grade 1 EAC or EHA; a body mass index > 30 kg/m2; a depth of myometrial invasion of less than 50% on MRI; a serum CA125 ≤ 30 U/mL. All patients received LNG-IUD and were randomized to observation (OBS), M (500 mg orally twice daily), or WL (pooled analysis). The primary outcome measure was the proportion of patients developing a pCR (defined as absence of any evidence of EAC or EHA) after 6 months. RESULTS From December 2012 to October 2019, 165 patients were enrolled and 154 completed the 6-months follow up. Women had a mean age of 53 years, and a mean BMI of 48 kg/m2. Ninety-six patients were diagnosed with EAC (58%) and 69 patients with EHA (42%). Thirty-five participants were randomized to OBS, 36 to WL and 47 to M (10 patients were withdrawn). After 6 months the rate of pCR was 61% (95% CI 42% to 77%) for OBS, 67% (95% CI 48% to 82%) for WL and 57% (95% CI 41% to 72%) for M. Across the three treatment groups, the pCR was 82% and 43% for EHA and EAC, respectively. CONCLUSION Complete response rates at 6 months were encouraging for patients with EAC and EHA across the three groups. TRIAL REGISTRATION U.S. National Library of Medicine, NCT01686126.

Abstract
INTRODUCTION Sentinel lymph node dissection is widely used in the staging of endometrial cancer. Variation in surgical techniques potentially impacts diagnostic accuracy and oncologic outcomes, and poses barriers to the comparison of outcomes across institutions or clinical trial sites. Standardization of surgical technique and surgical quality assessment tools are critical to the conduct of clinical trials. By identifying mandatory and prohibited steps of sentinel lymph node (SLN) dissection in endometrial cancer, the purpose of this study was to develop and validate a competency assessment tool for use in surgical quality assurance. METHODS A Delphi methodology was applied, included 35 expert gynecological oncology surgeons from 16 countries. Interviews identified key steps and tasks which were rated mandatory, optional, or prohibited using questionnaires. Using the surgical steps for which consensus was achieved, a competency assessment tool was developed and subjected to assessments of validity and reliability. RESULTS Seventy percent consensus agreement standardized the specific mandatory, optional, and prohibited steps of SLN dissection for endometrial cancer and informed the development of a competency assessment tool. Consensus agreement identified 21 mandatory and three prohibited steps to complete a SLN dissection. The competency assessment tool was used to rate surgical quality in three preselected videos, demonstrating clear separation in the rating of the skill level displayed with mean skills summary scores differing significantly between the three videos (F score=89.4; P<0.001). Internal consistency of the items was high (Cronbach α=0.88). CONCLUSION Specific mandatory and prohibited steps of SLN dissection in endometrial cancer have been identified and validated based on consensus among a large number of international experts. A competency assessment tool is now available and can be used for surgeon selection in clinical trials and for ongoing, prospective quality assurance in routine clinical care.

Abstract
BACKGROUND There are limited data from retrospective studies regarding whether survival outcomes after laparoscopic or robot-assisted radical hysterectomy (minimally invasive surgery) are equivalent to those after open abdominal radical hysterectomy (open surgery) among women with early-stage cervical cancer. METHODS In this trial involving patients with stage IA1 (lymphovascular invasion), IA2, or IB1 cervical cancer and a histologic subtype of squamous-cell carcinoma, adenocarcinoma, or adenosquamous carcinoma, we randomly assigned patients to undergo minimally invasive surgery or open surgery. The primary outcome was the rate of disease-free survival at 4.5 years, with noninferiority claimed if the lower boundary of the two-sided 95% confidence interval of the between-group difference (minimally invasive surgery minus open surgery) was greater than -7.2 percentage points (i.e., closer to zero). RESULTS A total of 319 patients were assigned to minimally invasive surgery and 312 to open surgery. Of the patients who were assigned to and underwent minimally invasive surgery, 84.4% underwent laparoscopy and 15.6% robot-assisted surgery. Overall, the mean age of the patients was 46.0 years. Most patients (91.9%) had stage IB1 disease. The two groups were similar with respect to histologic subtypes, the rate of lymphovascular invasion, rates of parametrial and lymph-node involvement, tumor size, tumor grade, and the rate of use of adjuvant therapy. The rate of disease-free survival at 4.5 years was 86.0% with minimally invasive surgery and 96.5% with open surgery, a difference of -10.6 percentage points (95% confidence interval [CI], -16.4 to -4.7). Minimally invasive surgery was associated with a lower rate of disease-free survival than open surgery (3-year rate, 91.2% vs. 97.1%; hazard ratio for disease recurrence or death from cervical cancer, 3.74; 95% CI, 1.63 to 8.58), a difference that remained after adjustment for age, body-mass index, stage of disease, lymphovascular invasion, and lymph-node involvement; minimally invasive surgery was also associated with a lower rate of overall survival (3-year rate, 93.8% vs. 99.0%; hazard ratio for death from any cause, 6.00; 95% CI, 1.77 to 20.30). CONCLUSIONS In this trial, minimally invasive radical hysterectomy was associated with lower rates of disease-free survival and overall survival than open abdominal radical hysterectomy among women with early-stage cervical cancer.

Abstract
Background: The relationship between diet and survival after ovarian cancer diagnosis is unclear as a result of a limited number of studies and inconsistent findings. Methods: We examined the association between pre-diagnostic diet and overall survival in a population-based cohort (n=811) of Australian women diagnosed with invasive epithelial ovarian cancer between 2002 and 2005. Diet was measured by validated food frequency questionnaire. Deaths were ascertained up to 31 August 2014 via medical record review and Australian National Death Index linkage. We conducted Cox proportional hazards regression analysis, controlling for diagnosis age, tumour stage, grade and subtype, residual disease, smoking status, body mass index, physical activity, marital status, and energy intake. Results: We observed improved survival with highest compared with lowest quartile of fibre intake (hazard ratio (HR)=0.69, 95% CI: 0.53–0.90, P-trend=0.002). There was a suggestion of better survival for women with highest compared with lowest intake category of green leafy vegetables (HR=0.79, 95% CI: 0.62–0.99), fish (HR=0.74, 95% CI: 0.57–0.95), poly- to mono-unsaturated fat ratio (HR=0.76, 95% CI: 0.59–0.98), and worse survival with higher glycaemic index (HR=1.28, 95% CI: 1.01–1.65, P-trend=0.03). Conclusions: The associations we observed between healthy components of diet pre-diagnosis and ovarian cancer survival raise the possibility that dietary choices after diagnosis may improve survival.

Abstract
IMPORTANCE Standard treatment for endometrial cancer involves removal of the uterus, tubes, ovaries, and lymph nodes. Few randomized trials have compared disease-free survival outcomes for surgical approaches. OBJECTIVE To investigate whether total laparoscopic hysterectomy (TLH) is equivalent to total abdominal hysterectomy (TAH) in women with treatment-naive endometrial cancer. DESIGN, SETTING, AND PARTICIPANTS The Laparoscopic Approach to Cancer of the Endometrium (LACE) trial was a multinational, randomized equivalence trial conducted between October 7, 2005, and June 30, 2010, in which 27 surgeons from 20 tertiary gynecological cancer centers in Australia, New Zealand, and Hong Kong randomized 760 women with stage I endometrioid endometrial cancer to either TLH or TAH. Follow-up ended on March 3, 2016. INTERVENTIONS Patients were randomly assigned to undergo TAH (n = 353) or TLH (n = 407). MAIN OUTCOMES AND MEASURES The primary outcome was disease-free survival, which was measured as the interval between surgery and the date of first recurrence, including disease progression or the development of a new primary cancer or death assessed at 4.5 years after randomization. The prespecified equivalence margin was 7% or less. Secondary outcomes included recurrence of endometrial cancer and overall survival. RESULTS Patients were followed up for a median of 4.5 years. Of 760 patients who were randomized (mean age, 63 years), 679 (89%) completed the trial. At 4.5 years of follow-up, disease-free survival was 81.3% in the TAH group and 81.6% in the TLH group. The disease-free survival rate difference was 0.3% (favoring TLH; 95% CI, -5.5% to 6.1%; P = .007), meeting criteria for equivalence. There was no statistically significant between-group difference in recurrence of endometrial cancer (28/353 in TAH group [7.9%] vs 33/407 in TLH group [8.1%]; risk difference, 0.2% [95% CI, -3.7% to 4.0%]; P = .93) or in overall survival (24/353 in TAH group [6.8%] vs 30/407 in TLH group [7.4%]; risk difference, 0.6% [95% CI, -3.0% to 4.2%]; P = .76). CONCLUSIONS AND RELEVANCE Among women with stage I endometrial cancer, the use of total abdominal hysterectomy compared with total laparoscopic hysterectomy resulted in equivalent disease-free survival at 4.5 years and no difference in overall survival. These findings support the use of laparoscopic hysterectomy for women with stage I endometrial cancer.

Abstract
BACKGROUND Radical trachelectomy and pelvic lymph node dissection are an increasingly recognised treatment for early cervical cancer in women wishing to retain their fertility. AIMS To analyse and summarise the outcomes of women having undergone radical trachelectomies at the Queensland Centre for Gynaecological Cancer (QCGC) between June 2000 and June 2012. METHODS Retrospective study of data collected on the QCGC database. RESULTS 17 women underwent radical trachelectomies, with six subsequently giving birth to a total of seven live term babies, all delivered by caesarean section. There was one-first trimester miscarriage, but no major obstetric complications. There have been no cancer recurrences, deaths or major complications. CONCLUSIONS Radical trachelectomy should be offered as an alternative treatment for women with early stage cervical cancer who wish to preserve their fertility as long as they are aware of the increased risk of infertility and preterm birth.

Abstract
Ovarian cancer, in particular epithelial ovarian cancer (EOC), is commonly diagnosed when the tumor has metastasized into the abdominal cavity with an accumulation of ascites fluid. Combining histopathology and genetic variations, EOC can be sub-grouped into Type-I and Type-II tumors, of which the latter are more aggressive and metastatic. Metastasis and chemoresistance are the key events associated with the tumor microenvironment that lead to a poor patient outcome. Kallikrein-related peptidases (KLKs) are aberrantly expressed in EOC, in particular, in the more metastatic Type-II tumors. KLKs are a family of 15 serine proteases that are expressed in diverse human tissues and involved in various patho-physiological processes. As extracellular enzymes, KLKs function in the hydrolysis of growth factors, proteases, cell membrane bound receptors, adhesion proteins, and cytokines initiating intracellular signaling pathways and their downstream events. High KLK levels are differentially associated with the prognosis of ovarian cancer patients, suggesting that they not only have application as biomarkers but also function in disease progression, and therefore are potential therapeutic targets. Recent studies have demonstrated the function of these proteases in promoting and/or suppressing the invasive behavior of ovarian cancer cells in metastasis in vitro and in vivo. Both conventional cell culture methods and three-dimensional platforms have been applied to mimic the ovarian cancer microenvironment of patients, such as the solid stromal matrix and ascites fluid. Here we summarize published studies to provide an overview of our understanding of the role of KLKs in EOC, and to lay the foundation for future research directions.

Abstract
Abstract
Purpose: To determine the relationship between obesity, diabetes, other major comorbidities and survival following a diagnosis of ovarian cancer.
Methods: We examined the association between obesity, as measured by body mass index (BMI), diabetes and other comorbidities and survival from ovarian cancer in a large (n=1404), population-based cohort of women diagnosed with epithelial ovarian cancer between 2002-2006. Information about pre-diagnostic BMI and medical history was obtained via a self-administered questionnaire. BMI at the commencement of primary chemotherapy and clinicopathologic data were abstracted from medical records and deaths were ascertained up to October 2011 via linkage with the Australian National Death Index. We also examined short- (≥5 years) and long-term (>5 years) survival, as well as survival differences by histological subtype. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were obtained using Cox regression.
Results: After adjustment, a survival disadvantage was observed for women who were obese prior to diagnosis compared to women in the normal BMI range (BMI 30-34.9:HR 1.21, 95%CI 0.99-1.48; BMI≥35:HR 1.19, 95%CI 0.92-1.55). The association was similar for BMI at the commencement of primary chemotherapy. There was a suggestion that the adverse association between obesity and survival time was restricted to women with serous or endometrioid histological subtypes. Obesity conferred a survival disadvantage for both short- and long-term survival, with a stronger association in long-term survivors. Diabetes and other comorbidities did not appear to influence survival overall; however appeared to be important in the sub-group of women surviving longer than 5 years (HR1.44 and HR1.64, respectively).
Conclusion: This is the first study to show that obesity is important in both short- and long-term survival following a diagnosis of ovarian cancer. More research examining diabetes, comorbidities and ovarian cancer survival should be conducted.

Abstract
BACKGROUND Since the introduction of the Pap smear screening, the incidence of squamous cell carcinoma (SCC) has decreased significantly, but the incidence of adenocarcinoma (AC) relative to SCC has increased. AIM To compare the Pap smear history of patients with AC and SCC of the cervix. METHODS Patients for the study were identified from the database of Queensland Centre for Gynaecological Cancer. Patients with AC and SCC were matched for age at diagnosis and International Federation of Gynecology and Obstetrics stage. The final population included 188 matched pairs, being 376 patients in total. Data were collected upon the histological type of cancer, result of the most recent Pap smear, date and result of the Pap smear prior to the most recent Pap smear and symptoms. Chi-squared tests and Fisher's exact test were used to compare the two patient groups for several variables. RESULTS Patients with AC had significantly more false-negative results on their most recent Pap smear (P<0.0001) than patients with SCC. The incidence of symptoms such as bleeding and/or vaginal discharge was comparable in patients with AC and SCC. The time between the most recent Pap smear and the diagnosis of cervical cancer was significantly shorter for patients with AC (P=0.01). CONCLUSIONS Patients with AC had Pap smears more regularly than those with SCC, and their most recent Pap smear was significantly more likely to be normal. Thus, Pap smear prior to a diagnosis of AC is more likely than SCC false-negative and therefore not indicative of cervical cancer.

Abstract
OBJECTIVE To evaluate the efficacy of routine follow-up in patients with recurrent uterine cancer. METHODS In a single institution study, a total of 2637 patients were treated curatively for uterine cancer from 1990 to 2006. A total of 438 patients experienced disease recurrence. Data for detailed analysis were available from 280 of the 438 patients. Prior to the diagnosis of recurrence, all patients had regular follow-up and were investigated through internal examination, vaginal vault cytology and imaging. Overall survival (OS) was the main study endpoint and was calculated from recurrence diagnosis to death or date censored. RESULTS Clinical and histopathological features as well as patterns of recurrence were similar in symptomatic and asymptomatic patients. Eighty-one patients (28.9%) were diagnosed with asymptomatic recurrence while 199 patients (71.1%) presented with symptomatic recurrence. The overall survival probability at 5 years was 41.0% and 28.9% respectively for asymptomatic and symptomatic patients (log-rank p=0.013). Those patients with stage 1 or 2 tumors of endometrioid type were found to have an overall survival probability at 5 years of 38.0% and 25.7% respectively for asymptomatic and symptomatic recurrence (log-rank p=0.05). The absence of symptoms did not impact on the outcome of patients with stage 3 tumors or tumors of non-endometrioid type. CONCLUSIONS While patients at low/intermediate risk of recurrence may benefit from intensive follow-up including internal examinations, routine vaginal vault cytology and imaging, high-risk patients might gain more from an alternate follow-up strategy with emphasis on imaging in conjunction with symptom education.

Abstract
BACKGROUND Total laparoscopic hysterectomy (TLH) is becoming more commonly used for gynaecological malignancies. AIMS To describe our experience with TLH since its introduction to our tertiary referral centre for gynaecological cancer in 2003. METHODS Retrospective analysis of the first 120 consecutive cases of TLH performed at our gynaecological cancer centre. Patients were divided into the first, second and third group of 40 patients. Operating time, estimated blood loss, hospital stay, conversion to laparotomy and intra- and postoperative morbidity were evaluated. RESULTS The three groups were similar with regard to baseline characteristics. For the entire group the mean hospital stay was 2.4 +/- 1.4 days and eight of 120 patients (6.6%) required conversion to laparotomy. Operating time, estimated blood loss and intraoperative morbidity were similar among the three groups. Postoperative morbidity was highest (25%) in the middle one-third of the patients (P = 0.022). The percentage of pelvic lymph node dissections increased from 2.5% in the first one-third of patients to 27.5% in the final one-third of patients (P = 0.003). CONCLUSIONS TLH can be established safely in a tertiary gynaecological cancer referral centre.

Abstract
BACKGROUND During major abdomino-pelvic surgery, there is a risk of severe haemorrhage. When routine measures at haemostasis fail, the overlay autogenous tissue (OAT) patch may be useful to control bleeding. CASE We present a case report of the use of the use of an OAT patch to control haemorrhage of the spleen incurred during tertiary cytoreduction. CONCLUSION The OAT patch should be considered in situations where bleeding is unable to be controlled after routine measures have failed and in instances other than for vascular injury alone. This technique has implications for practice in a wide range of gynaecologic oncology surgery.

Abstract
OBJECTIVES To assess the reliability and validity of the Functional Assessment of Cancer Therapy-Vulvar (FACT-V). METHODS Seventy-seven patients treated between January 1996 and January 2001 for cancer of the vulva completed the FACT-V, the Eastern Cooperative Oncology Group Performance Status Rating (ECOG-PSR) and the Hospital Anxiety and Depression Scale (HADS) once, 20 consecutive patients treated between February 2001 and October 2001 completed the questionnaires twice, once before surgery and at 2 months follow-up. The FACT-V scores were compared by patients' performance status, FIGO stage, recurrence, and age, and correlated to the HADS scores. Changes in the FACT-V from baseline to 2 months follow-up were evaluated to establish FACT-V's responsiveness to change. RESULTS The FACT-V's internal consistency was adequate (Chronbach's alpha range, 0.75 to 0.92). Patients with lower performance status, higher FIGO-stage or recurrent disease received lower FACT-V scores, indicating discriminant validity. The correlation between the FACT-V and the HADS were in the expected direction, indicating convergent and divergent validity. From pre- to post-surgery, scores in nine out of fifteen items of the vulvar cancer-specific subscale improved, while those of five items declined, indicating sensitivity of the vulvar cancer specific items to changes in patients' well-being. CONCLUSIONS The newly developed FACT-V provides a reliable and valid assessment of the quality of life of women with vulvar cancer. It can be used as a short measure of quality of life within research studies, and to facilitate communication about quality of life issues in clinical practice.

Abstract
OBJECTIVE To compare patterns of recurrence and disease-free survival (DFS) of node-positive and node-negative patients with advanced vulval squamous cell carcinoma (SCC). METHODS Fifty-five patients with FIGO stage III/IVA vulval SCC who had surgery at the Queensland Centre for Gynaecological Cancer from 1989 to 1999 were included. Patients were grouped as follows: Group A, pT3 N0; Group B, pT3 N1; Group C, pT4 N2. Treatment included surgery +/- postoperative radiotherapy. Multivariate Cox models were calculated to identify independent prognostic factors. RESULTS After a median follow-up of 96 months, 25 patients (45.5%) experienced recurrence at the vulva (n = 2), pelvis (n = 8), or distant sites (n = 15). Recurrence in the pelvis and at distant sites was more likely for patients in groups B and C (P 0.003). At 5 years the probability of DFS was 66.6%, 35.3%, and 39.8% for patients in groups A, B, and C, respectively (P 0.085). Patients with negative nodes (n = 15), one microscopic positive node (n = 11), and two or more positive nodes (n = 29) had a probability of DFS of 66.6%, 67.3%, and 26.1% at 5 years, respectively (P 0.005). CONCLUSION Patients with > or =2 positive groin nodes are at risk for distant failure. The DFS of patients with negative groin nodes and those with only one microscopic positive node is very similar. The prognosis of patients with > or =2 positive unilateral or bilateral groin nodes is similar. The current FIGO staging system inaccurately reflects prognosis for patients with advanced vulval cancer. Clinical trials are warranted to investigate the benefit of systemic treatment.

Abstract
OBJECTIVES The aims of this study were to assess outcomes and define prognostic factors for early-stage vaginal carcinoma. METHODS A retrospective analysis was performed of women with FIGO stages I and II vaginal carcinoma identified from the database of the Queensland Centre for Gynaecological Cancer between January 1982 and December 1998. RESULTS Seventy women were identified. The 5-year survivals for stages I and II carcinomas were 71 and 48%, respectively (P < 0.05). Sixty-one patients (87%) had squamous cell carcinomas with a 5-year survival of 68% versus 22% for adenocarcinomas (P < 0.01). Those women with grade 3 tumors had a 5-year survival of 40% versus 69% for grades 1 and 2 (P < 0.05). Tumor size and site were not significant prognostic factors. Patients treated by surgery alone or with combined surgery and radiotherapy had a significantly improved survival compared to the radiation alone group (P < 0.01). Eighty-five percent of recurrences were locoregional. The median time to relapse was 12 months after initiation of therapy. CONCLUSION Tumor morphology, grade, and stage are important prognostic indicators. Measures aimed at improving local control of the disease, including surgery, are necessary.

Abstract
To determine the impact of anemia before and during chemoradiation in patients with cervical cancer, we collected data on hemoglobin (Hb) levels before and during treatment from 60 unselected patients with cervical carcinoma. All patients had FIGO stage IB to IVA disease and were treated with concurrent chemoradiation for the aim of cure. Patients with an Hb value below or equal to the lower 25th quartile were considered anemic. Progression-free survival (PFS) was evaluated by univariate and multivariate analyses. After a median follow-up of 26.3 months, 20 patients developed disease progression. The lowest Hb during chemoradiation (nadir Hb), the stage of disease, and parametrial involvement were correlated significantly with PFS. On multivariate analysis, the nadir Hb (relative risk [RR] 0.29) and tumor stage (RR 3.4) remained the only prognostically relevant factors predicting PFS. At 60 months the PFS was 39.1% for anemic patients and 48.0% for nonanemic patients (P < 0.0002). In patients undergoing chemoradiation for cervical carcinoma, a low nadir Hb is highly predictive of shortened PFS, whereas the Hb before treatment is prognostically not significant.

Abstract
OBJECTIVE The aim of this study was to determine the prognostic significance of serosal involvement (SER), adnexal involvement (ADN), and positive peritoneal washings (PPW) in patients with Stage IIIA uterine cancer. We also sought to determine patterns of recurrence in patients with this disease. METHODS The records of 136 patients with Stage IIIA uterine cancer treated at the Queensland Centre for Gynecological Cancer between March 1983 and August 2001 were reviewed. One hundred thirty-six patients underwent surgery and 58 (42.6%) had full surgical staging. Seventy-five patients (55.2%) had external beam radiotherapy and/or brachytherapy postoperatively. Overall survival was the primary statistical endpoint. Statistical analysis included univariate and multivariate Cox models. RESULTS Forty-six patients (33.8%) had adnexal involvement, 23 (16.9%) had serosal involvement, and 40 (29.4%) had positive peritoneal washings. Median follow-up was 55.1 months (95% confidence interval, 36.9 to 73.4 months) after which time 71 patients (52.2%) remained alive. For patients with endometrioid adenocarcinoma, ADN and SER were associated with impaired survival on multivariate analysis (odds ratio 2.8 and 3.2, respectively). In the subgroup of patients with high-risk tumors (including papillary serous carcinomas, clear cell carcinomas, and uterine sarcomas), neither ADN, nor SER, nor PPW influenced survival. CONCLUSION Patients with Stage IIIA uterine cancer constitute a heterogeneous group. For patients with endometrioid adenocarcinoma, both ADN and SER, but not PPW, were associated with impaired prognosis. For patients with high-risk histological types, prognosis is poor for all three factors.

Abstract
OBJECTIVE The association between psammoma bodies on cervical smear (PBCS) and the presence of gynecological malignancy has been documented previously. The aim of this study was to determine the incidence of malignancy where psammoma bodies were detected on smear, to identify features that may be predictive of associated malignancy, and to make recommendations about management. METHODS The databases of two large private pathology laboratories were accessed to obtain details of all patients reported to have PBCS between April 1992 and May 2000. A retrospective review was then undertaken to determine if any patients were found to have gynecological malignancies. The appearances of the background cells on the cervical smear and details of clinical management were recorded and evaluated. RESULTS Twenty-two patients were found to have PBCS. Five patients were found to have a gynecological malignancy. These five patients were significantly older than the remaining patients. When these results were combined with all cases reported in the world literature, it became apparent that patients with coexisting malignancy were statistically significantly older than those not found to have malignancy (P < 0.0001). The cytological appearance of cells on the background smear was highly predictive of the presence or absence of malignancy. CONCLUSIONS There is an association between PBCS and genital tract malignancy. This association is much stronger for postmenopausal women. The background cytology is highly predictive of the presence of associated malignancy. There is a strong argument that all women with psammoma bodies on cervical smear should undergo smear review, pelvic ultrasonography, hysteroscopy and biopsy, and laparoscopy to exclude the presence of a gynecological malignancy. For younger reproductive-aged women, a negative workup is reassuring.

Abstract
OBJECTIVE To examine the feasibility and safety of a low anterior resection of the rectosigmoid plus adjacent pelvic tumour as part of primary cytoreduction for ovarian cancer. METHODS This study included 65 consecutive patients with primary ovarian cancer who had debulking surgery from 1996 through 2000. All patients underwent an en bloc resection of ovarian cancer and a rectosigmoid resection followed by an end-to-end anastomosis. Parameters for safety and efficacy were considered as primary statistical endpoints for the aim of this analysis. RESULTS Postoperative residual tumour was nil, <1 cm, and >1 cm in 14, 34, and 14 patients, respectively. The median postoperative hospital stay was 11 days (range, 6 to 50 days). Intraoperative complications included an injury to the urinary bladder in one patient. Postoperative complications included wound complications (n = 14, 21.5%), septicemia (n = 9, 13.8%), cardiac complications (n = 7, 10.8%), thromboembolic complications (n = 5, 7.7%), ileus (n = 2, 3.1%), anastomotic leak (n = 2, 3.1%), and fistula (n = 1, 1.5%). Reasons for a reoperation during the same admission included repair of an anastomotic leak (n = 1), postoperative hemorrhage (n = 1), and wound debridement (n = 1). Wound complications, septicemia, and anastomotic leak formation were more frequent in patients who had a serum albumin level of < or =30 g/L preoperatively. There was one surgically related mortality in a patient who died from a cerebral vascular accident 2 days postoperatively. CONCLUSIONS An en bloc resection as part of primary cytoreductive surgery for ovarian cancer is effective and its morbidity is acceptably low.

Abstract
BACKGROUND In patients undergoing radiation for cervical carcinoma, there is evidence that anemia is associated with an impaired outcome. For patients undergoing chemoradiation, there are no data available. The objective of this retrospective study was to examine the impact of anemia before and during chemoradiation in patients with cervical carcinoma. METHODS The authors collected data on hemoglobin (Hb) levels before and during treatment from 57 patients with cervical carcinoma. The stage of disease ranged between Stage IB and Stage IVA. All patients were treated with concurrent chemoradiation. Response to chemoradiation was evaluated by univariate and multivariate analyses. RESULTS The mean Hb level at the time of presentation was 12.9 +/- 1.6 g/dL in patients with a complete clinical response (CCR) and 12.1 +/- 1.4 g/dL in those with persistent disease (P = 0.126). In patients with a CCR, the mean nadir Hb level was 11.1 +/- 1.3 g/dL, and in patients with treatment failure, it was 9.8 +/- 1.8 g/dL (P = 0.008). A univariate logistic regression model demonstrated that the nadir Hb level was the most predictive factor for treatment failure (relative risk, 1.92; P = 0.015) followed by disease stage (relative risk, 0.51; P = 0.074). In a multivariate model, the nadir Hb level remained the only prognostically relevant factor predicting the response to chemoradiation. Only patients with nadir Hb values > 11 g/dL throughout chemoradiation had a more than 90% chance of achieving a CCR. CONCLUSIONS In patients undergoing chemoradiation for cervical carcinoma, the nadir Hb level is highly predictive of response to treatment, whereas the Hb level at the time of presentation is prognostically not significant.

Abstract
OBJECTIVE To assess the accuracy of intra-operative frozen section reports at identifying the features of high risk uterine disease compared with final histopathology. DESIGN Retrospective study. METHODS The records of 460 patients with uterine cancer registered with the Queensland Centre for Gynaecological Cancer between January 1, 1996 and December 31, 1998 were reviewed. Intra-operative frozen section was undertaken in 260 patients with endometrial adenocarcinoma. Frozen section pathology was compared with the final histopathology reports. Inter-observer reliability was assessed using percentage agreement and kappa statistics. Clinical notes were also reviewed to determine if errors resulted in sub-optimal patient care. RESULTS Respectively, tumour grade and depth of myometrial invasion were accurately reported in 88.6% of cases (expected 61.5%, Kappa 0.70) and 94.7% (expected 53.8%, Kappa 0.89). Errors were predominantly attributable to difficulties with respect to the interpretation of tumour grade. The error resulted in the patient receiving sub-optimal surgical management in only 11 cases (5.3%) CONCLUSION Frozen section is accurate at identifying the features of high risk uterine disease in the setting of endometrial cancer and can play an important role in directing primary operative management.

Abstract
OBJECTIVE The aim of this study is to look at the efficacy of extended surgical staging and postoperative vaginal vault brachytherapy in patients with Stage II (occult) endometrial carcinoma. METHODS Between January 1989 and December 1997, there were 30 patients with Stage II (occult) endometrial carcinoma who received postoperative vaginal vault brachytherapy as the only adjuvant treatment. The study group consisted of 15 of these patients who had extended surgical staging (including lymphadenectomy). RESULTS At a median follow-up of 36 months (range 17 to 113 months), there has been no recurrence. There were no major complications from surgery. Only 1 patient had mild rectal bleeding following vaginal vault brachytherapy and there were no grade 3 or 4 bowel toxicities. CONCLUSIONS Extended surgical staging and postoperative vaginal vault brachytherapy for Stage II (occult) endometrial carcinoma is associated with minimal morbidity and excellent survival.

Abstract
The prognostic significance of positive peritoneal cytology in endometrial carcinoma has led to the incorporation of peritoneal cytology into the current FIGO staging system. While cytology was shown to be prognostically relevant in patients with stage II and III disease, conflicting data exists about its significance in patients who would have been stage I but were classified as stage III solely and exclusively on the basis of positive peritoneal cytology (clinical stage I). Analysis was based on the data of 369 consecutive patients with clinical stage I endometrioid adenocarcinoma of the endometrium. Standard treatment consisted of an abdominal total hysterectomy, bilateral salpingo-oophorectomy with or without pelvic lymph node dissection. Peritoneal cytology was obtained at laparotomy by peritoneal washing of the pouch of Douglas and was considered positive if malignant cells could be detected regardless of the number of malignant cells present. Disease-free survival (DFS) was considered the primary statistical endpoint. In 13/369 (3.5%) patients, positive peritoneal cytology was found. The median follow-up was 29 months and 15 recurrences occurred. Peritoneal cytology was independent of the depth of myometrial invasion and the grade of tumour differentiation. Patients with negative washings had a DFS of 96% at 36 months compared with 67% for patients with positive washings (log-rank P<0.001). The presence of positive peritoneal cytology in patients with clinically stage I endometrioid adenocarcinoma of the endometrium is considered an adverse prognostic factor.

Abstract
This study reviews our experience with 7 patients with primary Bartholin gland cancer (BGC) treated at the Queensland Gynaecological Cancer Centre (QCGC) and compares this with previously published data. A retrospective clinicopathologic review of all patients with primary BGC treated at QCGC from 1988 to 2000 was performed. Of the 7 patients treated, all underwent primary surgery and 5 of the 7 patients received radiotherapy postoperatively. All patients presented with a local swelling or a lump. Two had associated discharge and 2 had associated pain. Of the 7 patients, 2, 3 and 2 respectively were classified as having Stage IB, II or III disease. Five of the 7 patients had squamous cell carcinoma (SCC), one had adenoid-cystic carcinoma and 1 had a small-cell neuroendocrine cancer of the Bartholin gland. None of the patients with SCC developed recurrent disease. The patient with adenoid-cystic carcinoma experienced local recurrences at 4 years and again at 5 years and 3 months. Nine years after primary treatment she was diagnosed with pulmonary metastases. The patient with small-cell neuroendocrine cancer of the Bartholin gland was considered tumour-free after operation. Thorough imaging, including a CT scan of her chest, abdomen and pelvis showed no evidence of disease. She died 1 year and three months after diagnosis from disseminated pulmonary disease. We present the first report of small cell neuroendocrine cancer of the Bartholin gland. Therapeutic principles in the management of vulval cancer at other sites appear to be appropriate for management of BGC.

Abstract
The purpose of this study was to review the experience with fallopian tube carcinoma in Queensland and to compare it with previously published data. Thirty-six patients with primary fallopian tube carcinoma treated at the Queensland Gynaecological Cancer Center from 1988 to 1999 were reviewed in a retrospective clinicopathologic study. All patients had primary surgery and 31/36 received chemotherapy postoperatively. Abnormal vaginal bleeding (15/36) and abdominal pain (14/36) were the most common presenting symptoms at the time of diagnosis. Median follow-up was 70.3 months and the median overall survival was 68.1 months. Surgical stage I disease (P = 0.02) and the absence of residual tumor after operation (P = 0.03) were the only factors associated with improved survival. Twenty of the 36 patients (55%) presented with stage I disease and survival was 62.7% at 5 years. No patient with postoperative residual tumor survived. The majority of the patients with fallopian tube carcinoma present with stage I disease at diagnosis, but their survival probability is low compared with that of other early stage gynecological malignancies. If primary surgical debulking cannot achieve macroscopic tumor clearence, the chance of survival is extremely low.

Abstract
OBJECTIVES The aim of this study is to examine the patterns of failure after extended surgical staging and postoperative vaginal vault brachytherapy as the only adjuvant treatment in high-risk surgical Stage I patients with endometrial carcinoma. METHODS The records of all patients with endometrial carcinoma (adenocarcinoma or adenosquamous) receiving vaginal vault brachytherapy as the only adjuvant treatment from January 1989 to December 1997 were examined. A total of 489 patients were found. Of these, 133 had extended surgical staging. The study group consists of 77 surgical Stage I patients with Substages IBG3 and any grade IC. Recurrences were recorded as in the vagina, pelvis, or distant. RESULTS The mean follow-up interval was 45 months (range 14 to 96 months). Eleven patients had recurrence (14%). Median time to recurrence was 15 months (range 6 to 56 months). Recurrences occurred in the vagina in 7, pelvis in 1, and distantly in 3 patients. Five of 7 vaginal recurrences occurred within 2 years. All patients with distant recurrence died from disease. One patient with pelvic recurrence is alive with disease. Only 1 patient with vaginal recurrence died from disease. Six patients with isolated recurrences in the vagina were successfully treated with radiotherapy with or without local excision. All 6 have no evidence of disease at follow-up (median survival 29 months, range 20 to 71 months). CONCLUSIONS The vagina remains the most common site of recurrence for high-risk surgical Stage I patients treated with postoperative vaginal vault brachytherapy. Close follow-up in the first 2 years is essential to detect isolated vaginal recurrences. These are amenable to salvage treatment with good disease-free survival.

Abstract
OBJECTIVE The aims of this study were to evaluate the management of Stage IIIB adenocarcinoma of the endometrium (EAC) and to determine the utility of the FIGO classification as it applies to patients with this category of disease and make recommendations on management. METHODS A retrospective review was undertaken of the database of the Queensland Centre for Gynaecological Cancer (QCGC) from January 1982 to December 1996. The records of all patients recorded as having Stage IIIB EAC were retrieved. After validation of the designated staging, the contemporary disease status was determined and clinicopathological details were extracted from case notes. RESULTS Of a total of 1940 patients with EAC treated by QCGC over the 15-year study period, 14 (0.7%) patients met the inclusion criteria. Nine patients (64%) presented with postmenopausal bleeding and the remaining patients presented with a variety of symptoms. There was no statistically significant difference in age between the study group and other patients with advanced stage EAC ranging from Stage IIIA to Stage IVB disease. Survival of patients with Stage IIIB disease was statistically significantly worse than that of patients with Stage IIIA disease, but was not statistically significantly different from patients with Stage IIIC, IVA, or IVB. While all patients had the unifying characteristic of metastatic disease in the vagina, the true extent of disease could not be determined by a full surgical staging procedure. Such optimal surgery was contraindicated in all patients because of the presence of significant coexisting medical conditions. Consequently, treatment was highly individualized. CONCLUSIONS Stage IIIB adenocarcinoma of the endometrium is an uncommon condition. Similar to other substages of advanced disease, it is associated with a poor prognosis and requires individualized management. The argument is presented that this substage could be eliminated and included with Stage IIIC disease.

Abstract
We aimed to evaluate the correlation between the histological grade of endometrial cancer diagnosed on endometrial biopsy or curettage, with the definitive grade and stage of lesion as determined by surgery and histopathological examination and to make recommendations about the suitability of conservative surgery based on pre-operative determination of the grade of endometrial adenocarcinoma. A retrospective review of all patients with endometrial adenocarcinoma presenting to the Queensland Centre for Gynaecological Cancer from 1 January 1996 to 31 December 1998 was undertaken. Clinical and pathological data was abstracted from medical records and case notes of 460 patients. All histological specimens were prospectively reviewed by a panel consisting of gynaecologic pathologists, gynaecologic oncologists and other doctors involved in the treatment of patients with gynaecological malignancies. The percentage of patients whose management would have been optimised by full surgical staging at the time of initial surgery was calculated. Only 60%, 71%, and 84 % of the patients with a presenting diagnosis of grade 1, 2 and 3 endometrial adenocarcinomas respectively had this confirmed on final histopathology. Furthermore, using established criteria, 30%, 46% and 100% of patients presenting with grade 1, 2 and 3 endometrial adenocarcinoma required full surgical staging at the time of their primary surgery There is poor correlation between the pre-operative grade of endometrial cancer and the grade as determined on analysis of the resected uterus. The correlation is poorest with grade 1 endometrial adenocarcinoma, where strongest consideration is given to conservative surgery and the avoidance of subspecialty referral. There is a strong argument that all patients with a diagnosis of endometrial cancer made on endometrial biopsy or curettage, regardless of grade of malignancy, should be offered surgery where the option to perform concurrent comprehensive surgical staging is available.

Abstract
We evaluated the management of patients with microinvasive adenocarcinoma of the cervix (MIAC), in particular, to determine the place of conservative surgery, and determine if the FIGO classification for MIAC is valid and equivalent to the classification as it applies to microinvasive squamous cancer. A review was undertaken of the database of the Queensland Centre for Gynaecological Cancer (QCGC) from January, 1986 to October, 1998. The records of all patients recorded as having MIAC were retrieved. Microinvasion was defined according to the 1995 FIGO classification as a depth of invasion of no greater than 5 mm and a horizontal dimension of no greater than 7 mm 30 patients were found to have been treated for MIAC. The vast majority (29) were asymptomatic, disease being discovered at the time of routine Papanicolaou smear. There was a 43% incidence of coexisting squamous intraepithelial neoplasia. Multifocal disease was found in 17% of patients and lymph-vascular positivity in 7%. Eighteen patients were treated with radical surgery and 13 with conservative surgery. There were no recurrences over a follow-up interval of 3-116 months. Of the 18 patients treated with radical surgery, none was found to have occult microscopic disease in the parametria or nodal metastases. A total of 27 ovaries were removed, all of which were free of disease. In this small study, MIAC appears to behave in a manner similar to the squamous equivalent. The results provide some justification for the FIGO classification of a microinvasive glandular neoplasm of the cervix. There is some support for a role for conservative surgery in managing this condition, but there is insufficient worldwide experience to make definitive recommendations.

Abstract
Malignant ovarian germ cell tumours (MOGCT) principally occur in girls and young women and are generally unilateral. Effective combination chemotherapy with conservative surgery has seen a dramatic improvement in survival rates. This increase has shifted the focus to long-term fertility and reproductive outcome. The present study describes 45 patients with MOGCT treated with conservative surgery to preserve fertility, with or without the addition of chemotherapy. The age range was 10 to 32 years with a mean of 20 years. The majority of the subjects had Stage 1 tumours; 44 underwent unilateral salpingo-oophorectomy and 1 patient ovarian cystectomy. Adjuvant chemotherapy was administered in 29 patients. Overall mean follow-up was 58.7 months. There were 4 recurrences and 2 deaths. Survival of those with Stage 1 disease was 97% and for advanced stages 87%. During chemotherapy 50% became amenorrhoeic but 96% resumed normal menstrual function on completion. Seven healthy babies were recorded in the chemotherapy group and no documented birth defects occurred in any of these. There was no case of persistent infertility; 3 patients experienced temporary problems. It is concluded that conservative fertility-sparing surgery is the treatment of choice in these young women and advanced disease is not necessarily a contraindication. The majority can anticipate normal menstrual function and fertility.

Abstract
Infiltrative endometriosis is an uncommon condition that may involve all pelvic organs and is associated with considerable morbidity. A small percentage of patients will have disease that is unresponsive to hormonal therapy and is unsuitable for conservative surgery. Presented is a review of 5 case reports of patients who required radical surgery for control of symptoms caused by endometriosis. Radical surgery was associated with minimal morbidity and a high rate of resolution of symptoms. Radical surgery should be considered as part of the treatment strategy particularly when there is evidence of endometriosis invading into the adjacent gastrointestinal tract or urinary tract.

Abstract
Epithelial ovarian tumours of low malignant potential (LMP) are known to have a generally good prognosis, although there is not universal agreement on all aspects of treatment. We report a series of 175 patients with LMP ovarian tumours referred to the Queensland Centre for Gynaecological Cancer between January, 1982 and December, 1993. Stage I disease accounted for 142 cases, with only 1 patient dead from disease at 293 months. Twenty nine patients in this group had conservative surgery with 1 recurrence only (in the contralateral ovary) giving a recurrence rate of 3.5%. Survival and treatment data for other stages are presented, and the current literature reviewed. It is suggested that early stage disease may be treated conservatively depending upon the patient's desire to retain reproductive capacity. While adjuvant therapy is not recommended, long-term follow-up is indicated. More advanced disease should be debulked to the smallest practical volume. The role of lymphadenectomy has been questioned, as survival has not been shown to be affected by treatment decisions made as a result of knowing the lymph node status. Whilst some centres give platinum-based adjuvant therapy, the evidence that it is beneficial is not supported by any prospective randomized trials.

Abstract
Uterine papillary serous carcinoma exemplifies the potential for Müllerian epithelium at any site to differentiate along histologic patterns that replicate Müllerian epithelium at other sites, especially when neoplastic. Papillary serous differentiation is most commonly associated with epithelial ovarian carcinoma. Papillary serous differentiation of endometrial malignancy is associated with a poor prognosis wrought mainly through the tendency to present as late- stage disease. There is a considerable discrepancy between clinical and surgical staging. Because surgical stage is the single most important prognostic factor, the need for standardized, accurate, and comprehensive staging is highlighted, particularly where experimental protocols are being evaluated. Similarly, there is a need for strict adherence to standardized histologic criteria and reporting, particularly in making the often subtle distinction between papillary endometrioid adenocarcinoma and UPSC. Because even the earliest stage of disease is associated with a poor prognosis, a case can be made for offering adjuvant therapy to all patients diagnosed with UPSC. No single adjuvant modality has emerged as preeminent. There is comparable response to both radiotherapy and chemotherapy regimens, suggesting a need to compare these regimens in a multicenter, randomized trial. Because UPSC constitutes up to 10% of all endometrial carcinomas, there should be no difficulty accruing sufficient numbers for meaningful analysis. Although such a study may provide clues to optimizing available adjuvant strategies, further improvement in treatment regimens is required to effectively alter the poor prognosis associated with this condition.

Abstract
Splenectomy is sometimes necessary to achieve optimal cytoreduction or manage iatrogenic injury in the surgical management of epithelial ovarian cancer (EOC) and related conditions. To determine the place of splenectomy in cytoreductive surgery a retrospective review was made of patient hospital records. Between April 1989 and August 1994, 18 patients were found to have undergone a splenectomy as a component of their surgery leading to optimal debulking. Morbidity attributable to the splenectomy was minimal, with no significant increase in operative time or blood loss. The morbidity attributable to the splenectomy was as follows: atelectasis and/or effusion (8), pancreatic tail injury (4), thrombocytosis > 10(6)/microliters (3), pancreatic pseudocyst (1), partial left adrenalectomy (1), and pulmonary embolism (1). There were no instances of overwhelming postsplenectomy infection. Five patients were anticipated to require splenectomy and may have benefitted from preoperative vaccination against potential pathogens. Three patients were found to have splenic parenchymal metastases. Consistent with the international literature, these patients had other features consistent with stage IV disease, recurrent disease, or poor survival. Consideration should be given to expanding the FIGO stage IV classification to include splenic parenchymal disease. Splenectomy is a feasible and safe procedure to facilitate optimal tumor debulking; however, the potential associated morbidity mitigates against this procedure if significant, suboptimal residual disease is left elsewhere.

Abstract
The management and obstetric outcome of 17 patients with systemic lupus erythematosus (SLE) complicating 42 pregnancies is presented. Similar to world figures there was a 14.3% incidence of therapeutic abortion, a 4.8% incidence of ectopic pregnancy, a 16.7% incidence of spontaneous abortion, a 23.8% incidence of prematurity, a 4.8% incidence of fetal death in utero (FDIU) and a 9.5% incidence of intrauterine growth retardation (IUGR). In patients with antiphospholipid antibodies the obstetric outcome was significantly worse. Pregnancies complicated by preexisting renal compromise all concluded with an adverse outcome to the conceptus. In light of the experiences at the Royal Women's Hospital and a review of the world literature, the need for a standardized approach to SLE in pregnancy and more importantly the need for a large, prospective randomized trial of low dose aspirin in these pregnancies is highlighted.

Abstract
Adenocarcinoma in situ (ACIS) of the uterine cervix is an increasingly recognized disease. Thirty-seven cases were reviewed to determine the effect of HPV, marital status, parity, smoking habit and age on the topography and behaviour of this lesion. Using a commercial probe, 25% of 28 lesions tested were positive for HPV 16/18. The presence of HPV and a history of smoking appeared to exert no significant influence upon the topography and behaviour of ACIS. Nulliparity and a history of never being married was associated with a significant reduction in the incidence of coexisting CIN lesions. Age less than 36 years was associated with a significant reduction in the proximal linear extent of ACIS. While hysterectomy is probably the definitive treatment for ACIS of the cervix, there is an important place for conservative management by conization alone. Patients younger than 36 years are most likely to be desirous of retained fertility and appear to have the lesions most amenable to conservative surgery.
