Background: Sentinel lymph node (SLN) dissection has been established as standard of care in many tumours. Its use in early cervical cancer is an area of increasing interest and some studies suggest a high detection rate., Aim: To explore feasibility of SLN dissection and establish the patient detection rate in women with early cervical cancer., Materials and Methods: All patients with early cervical cancer, International Federation of Gynaecology and Obstetrics (FIGO) 2018 Stage 1, of any histology who underwent SLN dissection from January 2017 to March 2023 were included. Patients were eligible if they had pelvic confined disease; no suspicious lymph nodes on pre-operative imaging or intra-operatively; tumours <4 cm at the time of surgery and no contra-indications to surgery. Patients were excluded if there was a known allergy to dye or less than six months follow-up data., Results: Sixty-two patients were included in the study and 53% had FIGO stage 1b1 disease. The overall bilateral SLN detection rate was 89%, and the side-specific rate was 94%. Where indocyanine green (ICG) was used alone, the bilateral detection rate was 87% and the side-specific rate was 93%. Where ICG was used with patent blue dye (PTB) the bilateral detection rate was 92% and the side-specific rate was 96%. Where PTB was used alone the bilateral detection rate was 85% and the side-specific rate was 92%. The node positive rate was 6% (7/124) which included isolated tumour cells in four patients., Conclusion: SLN dissection with ICG or PTB is feasible in early-stage cervical cancer., (© 2024 Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

Introduction: Borderline ovarian tumours (BOT) are a common epithelial ovarian tumours. Typically diagnosed at an early stage with a good prognosis, many BOT are treated conservatively. Recurrence is common. This update to our last audit in 1997 represents one of the largest audits of BOT to date., Materials and Methods: All patients with BOT managed at 'the hospital' from 1984 to 2021 were included. Expert pathology review was available., Results: There were 549 cases included. The recurrence rate was 5% (n = 29/549) with 1.4% (n = 8/549) undergoing malignant transformation. Three of the eight women who recurred as cancer died from their disease. Frozen section was predictive of histologic diagnosis in 92% (n = 55/60) of serous tumours (SBOT), but only 62% (n = 54/87) of mucinous tumours (MBOT). In MBOT where the appendix appeared normal intra-operatively, it was histologically benign in all cases (n = 63). In SBOT, the recurrence rate was 5/23 (22%), 12/52 (23%), 1/29 (3%) and 3% (P = <0.01) for unilateral cystectomy, unilateral oophorectomy ± cystectomy, bilateral oophorectomy, and bilateral oophorectomy with hysterectomy, respectively, as index procedure. In MBOT this correlated to 2/20 (10%), 3/93 (3%), 0 and 1/58 (2%), respectively., Discussion: This study describes important information correlating first surgical procedure and fertility-sparing surgery to recurrence and malignant transformation. For all BOT subtypes, fertility-preserving surgery increased the risk of recurrence and hysterectomy was not superior to removal of both ovaries. In MBOT, frozen section is of limited utility and the macroscopically normal appendix is very unlikely to be anything but benign, if MBOT is the true histologic diagnosis., (© 2024 Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

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., (© 2023 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

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., (© 2021 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.)

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., (© 2017 Commonwealth of Australia.

The aim of this study was, after induction of labour in women with a previous Caesarean section, to compare the outcome in women with a history of a previous vaginal delivery with women who had never delivered vaginally. A retrospective analysis was performed over a 2-year period, in a Dublin teaching hospital. One hundred and three women who had had 1 previous lower segment Caesarean section had labour induced. Particular attention was given to delivery outcome, history of a vaginal delivery, cervical effacement at induction, influence of epidural analgesia, indication for induction and incidence of uterine rupture. The repeat Caesarean section rate after induction was 20.4%. Of the 51 women who had never previously delivered vaginally, the repeat section rate was 37.3% compared with only 3.9% of the 52 women who had previously delivered vaginally (p < 0.01). Fourteen women who had never delivered vaginally had an uneffaced cervix at induction and the repeat Caesarean section rate in this group was 64.3%. The commonest indication for induction was a postdates pregnancy. The use of epidural analgesia was greater in women who had never delivered vaginally. There were 2 cases of uterine scar rupture. Induction of labour following Caesarean section is associated with a significantly higher incidence of repeat Caesarean section in women who have not had a previous vaginal delivery. If the cervix is not effaced at induction, the repeat Caesarean section rate is higher than if the cervix has started to efface.
