Objective: Optimal management of the contralateral groin in patients with early-stage vulvar squamous cell carcinoma (VSCC) and a metastatic unilateral inguinal sentinel lymph node (SN) is unclear. We analyzed patients who participated in GROINSS-V I or II to determine whether treatment of the contralateral groin can safely be omitted in patients with a unilateral metastatic SN., Methods: We selected the patients with a unilateral metastatic SN from the GROINSS-V I and II databases. We determined the incidence of contralateral additional non-SN metastases in patients with unilateral SN-metastasis who underwent bilateral inguinofemoral lymphadenectomy (IFL). In those who underwent only ipsilateral groin treatment or no further treatment, we determined the incidence of contralateral groin recurrences during follow-up., Results: Of 1912 patients with early-stage VSCC, 366 had a unilateral metastatic SN. Subsequently, 244 had an IFL or no treatment of the contralateral groin. In seven patients (7/244; 2.9% [95% CI: 1.4%-5.8%]) disease was diagnosed in the contralateral groin: five had contralateral non-SN metastasis at IFL and two developed an isolated contralateral groin recurrence after no further treatment. Five of them had a primary tumor ≥30 mm. Bilateral radiotherapy was administered in 122 patients, of whom one (1/122; 0.8% [95% CI: 0.1%-4.5%]) had a contralateral groin recurrence., Conclusion: The risk of contralateral lymph node metastases in patients with early-stage VSCC and a unilateral metastatic SN is low. It appears safe to limit groin treatment to unilateral IFL or inguinofemoral radiotherapy in these cases., (Copyright © 2022 The Authors. Published by Elsevier Inc. All rights reserved.)

Objective: Germline genetic testing is increasingly offered to patients with epithelial ovarian cancer by non-genetic healthcare professionals, so called mainstream genetic testing. The aim of this study was to evaluate the effect of implementing a mainstream genetic testing pathway on the percentage of newly diagnosed patients with epithelial ovarian cancer to whom genetic testing was offered and the genetics-related healthcare costs., Methods: The possible care pathways for genetic counseling and testing and their associated costs were mapped. Patient files from all newly diagnosed patients with epithelial ovarian cancer before (March 2016 - September 2017) and after (April 2018 - December 2019) implementing our mainstream genetic testing pathway were analyzed. Based on this analysis, the percentage of newly diagnosed patients to whom genetic testing was offered was assessed and genetics-related healthcare costs were calculated using a healthcare payer perspective based on a Diagnosis-Related Group financing approach., Results: Within six months after diagnosis, genetic testing was offered to 56% of patients before and to 70% of patients after implementation of our mainstream genetic testing pathway (p = 0.005). Genetics-related healthcare costs decreased from €3.511,29 per patient before implementation to €2.418,41 per patient after implementation of our mainstream genetic testing pathway (31% reduction, p = 0.000)., Conclusion: This study shows that mainstream genetic testing leads to a significantly higher proportion of newly diagnosed patients with epithelial ovarian cancer being offered germline genetic testing. In addition, it significantly reduces genetics-related healthcare costs per patient., Competing Interests: Declaration of Competing Interest AstraZeneca sponsored the training module that was developed as part of this project, and was not involved in the development of its content., (Copyright © 2022 The Author(s).

Background and Purpose: Brain metastases originating from gynaecological tumours are a rare phenomenon, but have an increasing incidence due to better targeted therapies. This study aimed to identify factors that predict survival in these patients, which can be used in creating a robust prognostic tool for shared decision making., Materials and Methods: We identified a consecutive cohort of 73 patients treated for gynaecological brain metastases in two tertiary institutions. Baseline demographics, pathology and serum CA-125 were included in a multivariable Cox proportional hazards model., Results: Median overall survival in our cohort was 14.4 months, with a one-year survival of 56.4% and a two-year survival of 39.1%. Thirty-eight patients (52.1%) had ovarian carcinoma as the primary malignancy. The following factors were significantly associated with survival: age (HR 1.05 per year), CA-125 (HR 1.02 par 50 U/ml), and uterine and vulvar primary tumours (when compared to ovarian carcinoma, with HRs 3.07 and 8.70). A post-hoc analysis with primary tumour site reclassified into ovary versus non-ovary showed a HR of 0.50 for ovarian primary tumour type., Conclusion: We have found that age, pathology and CA-125 are prognostic factors for survival in patients with brain metastases from gynaecological tumours. Our findings may provide a foundation for future development of prediction models, for the benefit of both patients and physicians., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2020 The Authors.)

Objective: Pelvic lymphadenectomy is considered the gold standard to diagnose and possibly treat lymphatic metastases in gynaecological cancer patients. The aim of this study is to evaluate whether all presurgical MRI detected lymph nodes were removed during the systematic pelvic lymph node dissection (PLND) in cervical cancer patients., Methods: 21 consecutive cervical cancer patients who were scheduled to undergo a PLND were evaluated by a MRI scan prior to surgery and 6 weeks afterwards. All patients had tumour metastasis negative lymph nodes at histopathological examination., Results: On average, 10 pelvic lymph nodes (range 5-17) per patient were detected by presurgical MRI. Postsurgical MRI scans showed that on average 1 (range 0-3) pelvic node per patient was not removed by surgery. In total, 14% of the presurgical MR detected nodes were not removed by surgery (31/225). Approximately half of all lymph nodes that remained after surgery were located in the obturator region. In spite of the remaining nodes, surgery and histopathological examination did detect more nodes than MRI: on average 21 lymph nodes per patient (range 9-59) were removed. Another 2 lymph nodes (range 0-6 per patient) were judged to be newly developed after surgery., Conclusion: Although surgery was able to remove many more lymph nodes than those detected by presurgical MRI, 14% of presurgical MRI detected lymph nodes were not removed by PLND. The value of MRI prior to surgery for the detection of pathological lymph nodes is a subject of further research.

Objective: Liquid-based cytology may offer improvements over conventional cytology for cervical cancer screening. The two cytology techniques were compared in a group of 86,469 women who participated in a population-based screening program. Using a nation-wide pathology database containing both cervical cytology and histology records for all patients, we compared the outcome of the two screenings methods with regard to the detection rate of histological proven abnormalities and the determination of the true false-negative rates for both methods., Methods: Two cohorts of women living in the same geographical region were used. Cohort 1 (n=51,154 women) was analysed using conventional cytology (conventional cohort) and cohort 2 (liquid cohort) (n=35,315 women) was analysed using liquid-based cytology (SurePath). The samples were processed in one laboratory. The results of histological follow up were available via a central database., Results: The rate of unsatisfactory slides was significantly lower using liquid-based cytology (0.13% vs. 0.89%, p<0.0001). Detection of ASCUS+ (Atypical squamous cells of unknown significance or higher abnormalities) was significantly higher using liquid-based cytology (2.97% vs. 1.64%, p<0.0001), mainly due to the increase in the ASCUS category. The percentage of histological abnormalities within the ASCUS samples was approximately equal in both cohorts, indicating that more true abnormal cases were detected using liquid-based cytology. The sensitivity for detection of a histological proven lesion is significantly higher in the liquid cohort compared to the conventional cohort (96.2% vs. 92.0%), with only a slight difference in specificity (97.8% vs. 98.2%)., Conclusion: This population study confirmed previous institution-based reports of decreased numbers of unsatisfactory samples based on liquid-based cytology and showed an increased sensitivity for the detection of cytological abnormalities that was validated by subsequent histological investigation.

Cutaneous metastasis of vaginal carcinoma is extremely rare. So far, the total number of reported skin metastasis of vaginal carcinoma is only one. We present another case with an unusual manifestation of vagina carcinoma metastasis: skin metastasis presenting as a leg ulcer on the lower leg.
