BACKGROUND: Gestational trophoblastic disease (GTD) is an uncommon but highly treatable condition. There is limited local evidence to guide therapy. AIMS: To report the experience of a statewide registry in the treatment of low-risk gestational trophoblastic neoplasia (GTN) over a 20-year period. MATERIALS AND METHODS: A retrospective review of the prospectively maintained GTD registry database was conducted. There were 144 patients identified with low-risk GTN, of which 115 were analysed. Patient demographics, treatment details and outcomes, including development of resistance, toxicity or relapse were reviewed. RESULTS: The incidence of GTD was 2.6/1000 live births. There was 100% survival. The mean time from diagnosis to commencing treatment was 1.9 days (range 0-29 days). Seventy-seven percent of patients treated with methotrexate achieved complete response. Thirteen patients (11.3%) required multi-agent chemotherapy, for the treatment of resistant or relapsed disease. There was a higher rate of treatment resistance in those with World Health Organization (WHO) risk scores 5-6 (odds ratio (OR) 6.56, 95% CI 1.73-24.27, P = 0.005) and those with pre-treatment human chorionic gonadotropin >10 000 (OR 4.00 95% CI 1.73-24.27 P = 0.007). Four patients (3.5%) were diagnosed with choriocarcinoma after commencing treatment. Nine patients (7.8%) had successful surgical treatment for GTN, both alone and in combination with chemotherapy. The relapse rate was 4.3%; all were treated successfully with a combination of chemotherapy and surgery, and 93.9% of patients completed follow up through the registry. CONCLUSIONS: Methotrexate is a highly effective treatment for low-risk GTN, especially with WHO risk score ≤4. The optimal treatment for those with risk scores of 5-6 requires further investigation.

The aim of the study is to provide a comprehensive assessment of incidence and survival trends of epithelial ovarian cancer (EOC) by histological subtype across seven high income countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway and the United Kingdom). Data on invasive EOC diagnosed in women aged 15 to 99 years during 1995 to 2014 were obtained from 20 cancer registries. Age standardized incidence rates and average annual percentage change were calculated by subtype for all ages and age groups (15-64 and 65-99 years). Net survival (NS) was estimated by subtype, age group and 5-year period using Pohar-Perme estimator. Our findings showed marked increase in serous carcinoma incidence was observed between 1995 and 2014 among women aged 65 to 99 years with average annual increase ranging between 2.2% and 5.8%. We documented a marked decrease in the incidence of adenocarcinoma "not otherwise specified" with estimates ranging between 4.4% and 7.4% in women aged 15 to 64 years and between 2.0% and 3.7% among the older age group. Improved survival, combining all EOC subtypes, was observed for all ages combined over the 20-year study period in all countries with 5-year NS absolute percent change ranging between 5.0 in Canada and 12.6 in Denmark. Several factors such as changes in guidelines and advancement in diagnostic tools may potentially influence the observed shift in histological subtypes and temporal trends. Progress in clinical management and treatment over the past decades potentially plays a role in the observed improvements in EOC survival.

Tumors of the breast and reproductive organs that occur in children, adolescents, and young adults (AYA) have different biological features and can present special challenges. Although prognosis for these tumors is generally favorable, the long-term effects of treatment can be debilitating. Treatments are often multimodal and may include surgery as well as chemotherapy and/or radiation, which can cause considerable distress and anxiety related to loss of femininity or masculinity, concern over future fertility, or sexual dysfunction. Thus, tumors of the reproductive organs in pediatric/AYA patients require special consideration of the treatment effects beyond the intended oncologic outcome. Multidisciplinary teams should be involved in their care and address issues of fertility, sexual dysfunction, and psychosexual concerns before treatment begins. This review addresses histology, risk factors, prognosis, staging and treatment of gynecologic, breast and testicular cancers in pediatric and AYA patients.

OBJECTIVE: To investigate quality of life (QoL) and association with surgical complexity and disease burden after surgical resection for advanced ovarian cancer in centres with variation in surgical approach. DESIGN: Prospective multicentre observational study. SETTING: Gynaecological cancer surgery centres in the UK, Kolkata, India, and Melbourne, Australia. SAMPLE: Patients undergoing surgical resection (with low, intermediate or high surgical complexity score, SCS) for late-stage ovarian cancer. MAIN OUTCOME MEASURES: Primary: change in global score on the European Organisation for Research and Treatment of Cancer (EORTC) core quality-of-life questionnaire (QLQ-C30). Secondary: EORTC ovarian cancer module (OV28), progression-free survival. RESULTS: Patients' preoperative disease burden and SCS varied between centres, confirming differences in surgical ethos. QoL response rates were 90% up to 18 months. Mean change from the pre-surgical baseline in the EORTC QLQ-C30 was 3.4 (SD 1.8, n = 88) in the low, 4.0 (SD 2.1, n = 55) in the intermediate and 4.3 (SD 2.1, n = 52) in the high-SCS group after 6 weeks (p = 0.048), and 4.3 (SD 2.1, n = 51), 5.1 (SD 2.2, n = 41) and 5.1 (SD 2.2, n = 35), respectively, after 12 months (p = 0.133). In a repeated-measures model, there were no clinically or statistically meaningful differences in EORTC QLQ-C30 global scores between the three SCS groups (p = 0.840), but there was a small statistically significant improvement in all groups over time (p < 0.001). The high-SCS group experienced small to moderate decreases in physical (p = 0.004), role (p = 0.016) and emotional (p = 0.001) function at 6 weeks post-surgery, which resolved by 6-12 months. CONCLUSIONS: The global QoL of patients undergoing low-, intermediate- and high-SCS surgery improved at 12 months after surgery and was no worse in patients undergoing extensive surgery. TWEETABLE ABSTRACT: Compared with surgery of lower complexity, extensive surgery does not result in poore

BACKGROUND: Human epididymis protein 4 (HE4) has shown promising utility as a prognostic biomarker in endometrial cancer. Increased serum HE4 levels may be associated with deeper myometrial invasion, extrauterine disease and poorer prognosis. AIM: To evaluate the use of serum HE4 level, compared to and alongside other investigations, to accurately guide management in apparent early-stage endometrial cancer. MATERIALS AND METHODS: This is a single-site prospective study of 100 patients with histologically confirmed endometrial cancer. All patients underwent preoperative measurements of HE4 and CA125 levels and a preoperative magnetic resonance imaging (MRI) to assess the depth of invasion, nodal status and tumour size. Correlation was sought between serum HE4 level, CA125 level, MRI findings and intra-operative frozen section with tumour type, grade and stage. RESULTS: While both median HE4 and CA125 levels were higher with worsening clinicopathological features, serum HE4 level showed a more consistent association with high-risk features. Patients with a low-grade biopsy preoperatively and a low HE4 level (<70 pmol/L) demonstrated an 86.8% likelihood of having low-risk disease on final histopathology. In comparison, preoperative MRI or intraoperative frozen section alongside a low-grade biopsy demonstrated a similar likelihood of 86.2 and 87.7%, respectively. CONCLUSIONS: When used in conjunction with an initial low-grade endometrial biopsy, serum HE4 level demonstrated a similar likelihood to both preoperative MRI and intraoperative frozen section in identifying low-risk disease on final histopathology. As a triaging tool this may be significant given that a preoperative, serum-based assay would likely be the least invasive, least resource-intensive and most cost-effective approach.

BACKGROUND: Endometrial cancer is the most common invasive gynaecological cancer in Australia. Despite the fact that review after treatment of early endometrial cancer has not been shown to detect recurrent disease, practice at several hospitals brings women back for specialist hospital review for 5 years after definitive cancer surgery. AIM: Implement an improved model of follow-up care following hospital treatment for early endometrial cancer. EVALUATION METHODS: Quantitative and qualitative. RESULTS: Seventy-three of the eligible 81 women undertook the model of care. All general practitioners (GPs) agreed to follow-up care. Thirty-one women (42%) and 37 GPs (51%) returned surveys. All women found the nurse consultation very useful or useful with 77% reporting making lifestyle changes and 87% found the GP consultation very useful or useful with 72% reporting making lifestyle changes. Eighty-nine percent of GPs found the care plan useful, 94% set up patient recall systems, 79% used the care plan to develop their own care plan, 100% felt confident in providing follow-up care with 91% reporting the care plan and hospital processes improved their confidence. Comparison with the pre-cohort women showed: higher rates of communication at various care points to GPs (from P < 0.001); more referrals (P < 0.001); and a projected decrease of nine hospital doctor appointments per patient. DISCUSSION: With an increasing number of people surviving cancer, in order to address holistic health needs and maintain tertiary service capacity, general practice will be required to provide more follow-up care. Our model demonstrates an acceptable and quality mechanism for this to occur.
