Human osteosarcoma usually presented a high tendency to metastatic spread and caused poor outcomes, however, the underlying mechanism was still largely unknown. In the present study, using a series of in vitro experiments and an animal model, we investigated the roles of HOX antisense intergenic RNA (HOTAIR) during the proliferation and invasion of osteosarcoma. According with our results, HOTAIR was commonly overexpressed in osteosarcoma, which significantly correlated with advanced tumor stage, highly histological grade and poor prognosis. In vitro and in vivo experiments demonstrated that knockdown of HOTAIR could notably suppress cellular proliferation, inhibit invasion and decrease the secretion of MMP2 and MMP9 in osteosarcoma. Collectively, our results suggested that HOTAIR might be a potent therapeutic target for osteosarcoma.

Objective: To compare the safety between cervical conization (CC) alone and hysterectomy for patients with adenocarcinoma in situ (AIS) of the cervix. Methods: Patients diagnosed with AIS after CC during 2007–2021 were identified by computerized databases at Women’s Hospital of Zhejiang University School of Medicine. A total of 453 AIS patients were divided into 2 groups according to uterus preservation: hysterectomy group (n=300) and CC(s) alone group (n=153). The prevalence of residual disease and disease recurrence was compared between patients treated by CC(s) alone and hysterectomy. The prevalence of residual disease in specimens from women who had a hysterectomy and repeat CC were compared between positive and negative margins of CC. The factors influencing residual disease and disease recurrence were assessed. Results: Among 310 specimens from women who had a hysterectomy or repeat CC, the prevalence of residual disease was 50.6% (45/89) for a positive margin and 2.3% (5/221) for a negative margin (p=0.000). Four patients had recurrence of vaginal intraepithelial neoplasia in those treated by hysterectomy and one had recurrence of cervical squamous intraepithelial neoplasia in those treated by CC(s) alone. The prevalence of recurrence was 0.7% (1/153) for CC(s) alone and 1.3% (4/300) for hysterectomy (p=0.431). Hysterectomy did not influence residual disease or disease recurrence. Conclusion: CC is an efficacious and safe option for patients with AIS of the cervix provided the margin is negative.

Background: The use of molecular categorisation is shifting paradigm towards the use of molecular information to refine risk stratification in endometrial cancer (EC). To date, evidence to support molecular-guided therapies is limited to retrospective studies and secondary molecular analyses of patients receiving standard treatment. The PROBEAT study is the first randomized phase III trial to evaluate tailored adjuvant treatment based on WHO-endorsed molecular classification in Chinese EC patients. It is expected to provide a clinical decision-making tool for adjuvant treatment of patients with high-intermediate risk (HIR) or intermediate risk (IR) EC to better optimise and personalise patient care and increase relapse-free survival. Methods: The PROBEAT trial is a prospective, multicentre study led by Women’s Hospital of Zhejiang University Gynaecologic Oncology Group. Recruitment started on January 24, 2022, and 590 patients with HIR or IR endometrioid EC are expected to be recruited from 13 clinical centres in China. All tumor tissues will be classified into four molecular subtypes (POLEmut, MMRd, p53abn, or NSMP) based on WHO-endorsed molecular classification. Patients will be randomly assigned at a 2:1 ratio to either experimental arm and will receive molecular profile-based adjuvant treatment (observation in the POLEmut subgroup, vaginal brachytherapy in the MMRd or NSMP subgroup, or chemoradiotherapy in the p53abn subgroup) or to standard arm and will receive preferred adjuvant radiotherapy as recommended by the recent National Comprehensive Cancer Network guidelines version 1 (2022). The primary outcome is 3-year rates of recurrence. Secondary outcomes are relapse-free survival, overall survival, adverse events and health-related cancer-specific quality of life.
