Setting/sample: HPV-positive women recruited from the general cervical screening population.

GTN Diagnosis and Staging.

Majority of gestational trophoblastic neoplasia (GTN) follows molar pregnancies where diagnosis is mostly based on persistent or rising serum human chorionic gonadotrophin (hCG). Diagnosis of GTN could be based on clinical presentation, serum hCG measurement, imaging, histology, and genotyping. A high index of suspicion in women of reproductive age presenting with abnormal vaginal bleeding or unusual systematic presentation is important.

Acceptability of self-collected vaginal samples for human papillomavirus testing for primary cervical cancer screening: comparison of face-to-face and online recruitment modes.

Methods: Women aged 30-65 years were invited to participate by distributing the study information pamphlets at the specialist clinics of a regional acute hospital. Those who were interested in participating were given the option to join directly face-to-face or through an online website.

The Value of Four-Quadrant Cervical Biopsy in Women with Different Colposcopic Impressions.

The aim of this study was to compare the diagnostic efficacy of colposcopic-directed biopsy and four-quadrant biopsy in detecting high-grade cervical intra-epithelial neoplasia (CIN). Women attending three women's clinics for routine cervical screening were recruited. Colposcopy was arranged for women with any cytologic abnormalities greater than atypical squamous cells of undetermined significance (ASCUS), two consecutive ASCUS results or positive HPV testing.

Learning from mothers' success in breastfeeding maintenance: coping strategies and cues to action.

This study aimed to gain insight from mothers who were successful in breastfeeding maintenance to develop interventions for promoting breastfeeding maintenance. Following the phenomenological framework, this qualitative study recruited mothers who had maintained breastfeeding for at least 4 months for in-depth interviews. A total of 30 in-depth interviews were completed.

Patient-Initiated Follow-Up in Ovarian Cancer.

This study aimed to assess the feasibility of patient-initiated follow-up (PIFU) in combination with regular tumour marker monitoring as an alternative to conventional hospital follow-up for ovarian cancer survivors. Women who had recently completed treatment for ovarian cancer and had a raised pre-treatment tumour marker were recruited. Participants were allocated to PIFU (intervention group) or conventional hospital follow-up (control group) according to their own preference.

Outcome after loop electrosurgical excision procedure for cervical high-grade squamous intraepithelial lesion.

Objective: The dilemma in treating cervical high-grade squamous intraepithelial lesion (HSIL) is how to achieve complete excision to minimize the risk of cervical cancer while sparing the anatomy of the cervix and its ability to function during pregnancy. The optimal management for positive margins after excisional treatment is still controversial. This study was conducted to determine the clinical and histologic predictors of residual/recurrent HSIL and assess the outcome of women with positive margin.

A patient with relapsed high-grade serous ovarian carcinoma with somatic mutations treated with PARPi monotherapy: a case report.

We report our experience in the management of a relapsed ovarian cancer patient with somatic mutation, treated with olaparib monotherapy. The patient was diagnosed with stage 4 high-grade serous ovarian carcinoma and was treated with neoadjuvant chemotherapy, cytoreductive surgery, and postoperative chemotherapy. After a second cancer recurrence, she underwent FoundationOne CDx testing following disease progression on multiple lines of chemotherapy.

Association between High Diffusion-Weighted Imaging-Derived Functional Tumor Burden of Peritoneal Carcinomatosis and Overall Survival in Patients with Advanced Ovarian Carcinoma.

Human Papillomavirus Self-Sampling for Primary Cervical Cancer Screening in Under-Screened Women in Hong Kong during the COVID-19 Pandemic.

The aim of this study was to assess the effectiveness of HPV self-sampling for cervical cancer screening and the best means of service delivery, with a specific focus on under-screened women, particularly during the COVID-19 pandemic. Using three arms of service delivery (social media, school outreach and underserved outreach), we recruited under-screened women aged 30-65 years from two population groups: the general public and specific underserved communities, from whom self-sampled specimens and optional clinician-sampled cervical specimens were obtained for HPV testing. A total of 521 self-sampling kits were distributed, of which 321 were returned, giving an overall uptake rate of 61.

Diagnostic Performance of Risk of Malignancy Algorithm (ROMA), Risk of Malignancy Index (RMI) and Expert Ultrasound Assessment in a Pelvic Mass Classified as Inconclusive by International Ovarian Tumour Analysis (IOTA) Simple Rules.

The accurate prediction of malignancy for a pelvic mass detected on ultrasound allows for appropriate referral to specialised care. IOTA simple rules are one of the best methods but are inconclusive in 25% of cases, where subjective assessment by an expert sonographer is recommended but may not always be available. In the present paper, we evaluate the methods for assessing the nature of a pelvic mass, including IOTA with subjective assessment by expert ultrasound, RMI and ROMA.

Role of adjuvant and post-surgical treatment in gynaecological cancer.

Adjuvant and post-operative therapy aimed at reducing the risk of disease recurrence and improving potential for cure can be broadly categorised into systemic and locoregional treatment. For epithelial ovarian cancer, cytoreductive surgery and platinum-based chemotherapy is the mainstay management. Maintenance therapy with PARPi is a state-of-the-art option for women with advanced disease following complete or partial response to first-line platinum-based chemotherapy, particularly those with BRCA mutations.

Olaparib dose re-escalation in ovarian cancer patients who experienced severe and/or uncommon adverse events: A case series.

Aim: Few real-world studies have reported detailed management and dose adjustment strategies of adverse events (AEs) of ovarian cancer (OC) patients treated with the poly(adenosine diphosphate-ribose) polymerase inhibitor olaparib. This case series aimed to describe olaparib AEs in Chinese OC patients in real-life settings and to explore dose modification strategies.

Methods: We conducted a detailed examination of the clinical records of OC patients who were treated with olaparib at the Gynecologic Oncology Unit in Hong Kong from September 2015 to December 2019, including baseline characteristics, treatment outcomes, AEs, and management strategies, particularly dose modifications.

Surgery including fertility-sparing treatment of GTD.

Gestational trophoblastic disease (GTD) consists of a spectrum of diseases, including hydatidiform moles, invasive mole, metastatic mole, choriocarcinoma, placental site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT). GTD is a relatively uncommon disease occurring in women of reproductive age, with high cure rates. Primary treatment of hydatidiform moles includes uterine evacuation, followed by close monitoring of serial hCG levels to detect for post-molar gestational trophoblastic neoplasia (GTN).

Tamoxifen use in recurrent ovarian cancer in a Chinese population: A 15 -year clinical experience in a tertiary referral center.

Aim: To review the clinical use and the effectiveness of tamoxifen in patients with advanced or recurrent ovarian cancer.

Methods: A retrospective review of clinical records was conducted in patients who received tamoxifen for the treatment of ovarian cancer between 2002 and 2016. We reviewed the clinical setting that it was given, duration of use, patients' tolerability, clinical benefit and progression-free survival.

Nurse-led follow-up in survivorship care of gynaecological malignancies-A randomised controlled trial.

Objective: To assess clinical and psychosocial outcomes of nurse-led follow-up in survivorship care of gynaecological malignancies.

Methods: Women with endometrial or ovarian cancer who were attending regular post-treatment follow-up at a tertiary referral centre were randomised into two groups-group-1: telephone follow-up by nurses and group-2: gynaecologists-led clinic follow-up. Women in group-1 were asked about their symptoms and quality of life (QoL) by nurses.

PDK1 promotes ovarian cancer metastasis by modulating tumor-mesothelial adhesion, invasion, and angiogenesis via α5β1 integrin and JNK/IL-8 signaling.

Ovarian cancer is the most lethal gynecological malignancies owing to the lack of definitive symptoms until development of widespread metastases. Identification of novel prognostic and therapeutic targets is therefore an urgent need to improve survival. Here, we demonstrated high expression of the mitochondrial gatekeeping enzyme, pyruvate dehydrogenase kinase 1 (PDK1), in both clinical samples and cell lines of ovarian cancer.

Targeting of lipid metabolism with a metabolic inhibitor cocktail eradicates peritoneal metastases in ovarian cancer cells.

Ovarian cancer is an intra-abdominal tumor in which the presence of ascites facilitates metastatic dissemination, and associated with poor prognosis. However, the significance of metabolic alterations in ovarian cancer cells in the ascites microenvironment remains unclear. Here we show ovarian cancer cells exhibited increased aggressiveness in ascites microenvironment via reprogramming of lipid metabolism.

A Case Series of Five Patients With Pure or Mixed Gestational Epithelioid Trophoblastic Tumors and a Literature Review on Mixed Tumors.

Objectives: To review the clinicopathologic features of five patients with epithelioid trophoblastic tumor (ETT).

Methods: Characteristics of patients diagnosed with ETT in 2000 to 2012 were reviewed.

Results: Among 190 patients with gestational trophoblastic neoplasia (GTN), two had pure ETT and three had mixed ETT and choriocarcinoma.

GRO-α and IL-8 enhance ovarian cancer metastatic potential via the CXCR2-mediated TAK1/NFκB signaling cascade.

Intraperitoneal metastasis is a common occurrence and is usually involved in the poor prognosis of ovarian cancer. Its specific metastatic pattern implies that certain indispensable microenvironmental factors secreted in the peritoneal cavity can direct metastatic ovarian cancer cells to permissive niches for secondary lesion formation. However, the underlying molecular mechanisms are ill defined.

Methylation-associated silencing of promotes ovarian cancer aggressiveness by targeting GRB7 and MAPK/ERK pathways.

Human growth factor receptor-bound protein-7 (GRB7) is a pivotal mediator involved in receptor tyrosine kinase signaling and governing diverse cellular processes. Aberrant upregulation of GRB7 is frequently associated with the progression of human cancers. However, the molecular mechanisms leading to the upregulation of GRB7 remain largely unknown.

Impact of different educational interventions on psychosocial well-being of women with a positive high-risk human papillomavirus and normal cervical cytology: a randomised trial.

Introduction: The aim of this study was to compare the effect of two educational interventions on the psychosocial well-being of Hong Kong Chinese women who have a positive high-risk human papillomavirus (HPV) test and normal cervical cytology.

Methods: Participants were randomised into either leaflet group, in which a written HPV factsheet was provided; or counselling group, in which a didactic HPV presentation in person in addition to the factsheet was provided. Women's psychological conditions were assessed by self-administered questionnaires at pre, post (within one week) and 6 months after the educational interventions.
