Neoadjuvant Chemotherapy with Dual Immune Checkpoint Inhibitors for Advanced-Stage Ovarian Cancer: Final Analysis of TRU-D Phase II Nonrandomized Clinical Trial
Abstract Purpose: This open-label, investigator-initiated, phase II study was conducted to evaluate the safety, survival, and neoadjuvant outcomes of neoadjuvant chemotherapy (NAC) combined with dual immune checkpoint inhibitors in advanced-stage epithelial ovarian cancer (EOC). Patients and Methods: Between June 2019 and July 2021, 45 patients with unresectable stage III to IV EOC were enrolled. The patients received three cycles of NAC combined with durvalumab and tremelimumab. All patients underwent interval debulking surgery and received three cycles of durvalumab and adjuvant chemotherapy, followed by 12 cycles of durvalumab as maintenance therapy. The primary endpoint was the 12-month progression-free survival (PFS) rate; the secondary endpoints were the objective response rate after NAC, a chemotherapy response score, pathologic complete response, overall survival, and safety. The preplanned exploratory analyses assessed the lymphocyte infiltration, PD-L1 expression, and genomic profiles of pretreatment tumors. Results: The 12-month PFS rate was 65.9% [95% confidence interval (CI), 52.8–not estimated (NE)], whereas the 24- and 30-month PFS rates were 38.6% (95% CI, 26.7–NE) and 36.4% (95% CI, 24.7–NE), respectively. After NAC, the objective response rate was 86.7%, whereas 14 patients (31.1%) had a chemotherapy response score of three, and five (11.1%) achieved pathologic complete response. The 30-month overall survival rate was 87.7%. The most common grade ≥3 adverse event was neutropenia (26.7%). In an exploratory analysis, patients with pre-NAC tumors showing PD-L1 (combined positive score) ≥1, high Mutation Signature 3, and a high extracellular matrix signature demonstrated improved PFS outcomes. Conclusions: NAC combined with dual immune checkpoint inhibitors is feasible for advanced-stage EOC and shows promising activity with a durable clinical response.
Clinical practice guidelines for cervical cancer: an update of the Korean Society of Gynecologic Oncology Guidelines
We describe the updated Korean Society of Gynecologic Oncology (KSGO) practice guideline for the management of cervical cancer, version 5.1. The KSGO announced the fifth version of its clinical practice guidelines for the management of cervical cancer in March 2024. The selection of the key questions and the systematic reviews were based on data available up to December 2022. Between 2023 and 2024, substantial findings from large-scale clinical trials and new advancements in cervical cancer research remarkably emerged. Therefore, based on the existing version 5.0, we updated the guidelines with newly accumulated clinical data and added 4 new key questions reflecting the latest insights in the field of cervical cancer. For each question, recommendation was formulated with corresponding level of evidence and grade of recommendation, all established through expert consensus.
Clinical practice guidelines for cervical cancer: the Korean Society of Gynecologic Oncology guidelines
This fifth revised version of the Korean Society of Gynecologic Oncology practice guidelines for the management of cervical cancer incorporates recent research findings and changes in treatment strategies based on version 4.0 released in 2020. Each key question was developed by focusing on recent notable insights and crucial contemporary issues in the field of cervical cancer. These questions were evaluated for their significance and impact on the current treatment and were finalized through voting by the development committee. The selected key questions were as follows: the efficacy and safety of immune checkpoint inhibitors as first- or second-line treatment for recurrent or metastatic cervical cancer; the oncologic safety of minimally invasive radical hysterectomy in early stage cervical cancer; the efficacy and safety of adjuvant systemic treatment after concurrent chemoradiotherapy in locally advanced cervical cancer; and the oncologic safety of sentinel lymph node mapping compared to pelvic lymph node dissection. The recommendations, directions, and strengths of this guideline were based on systematic reviews and meta-analyses, and were finally confirmed through public hearings and external reviews. In this study, we describe the revised practice guidelines for the management of cervical cancer.
Comparisons of survival outcomes between bevacizumab and olaparib inBRCA-mutated, platinum-sensitive relapsed ovarian cancer: a Korean Gynecologic Oncology Group study (KGOG 3052)
To compare survival outcomes between bevacizumab (BEV) and olaparib (OLA) maintenance therapy in From 10 institutions, we identified HGSOC patients with germline and/or somatic Overall, OLA users showed significantly better progression-free survival (PFS) than BEV users (median, 23.8 vs. 17.4 months; p=0.004). Before matching, PFS improved in the OLA intent group but marginal statistical significance (p=0.057). After matching, multivariate analyses adjusting confounders identified intention-to-treat OLA as an independent favorable prognostic factor for PFS in the OLA 65P (adjusted hazard ratio [aHR]=0.505; 95% confidence interval [CI]=0.280-0.911; p=0.023) to OLA 100P (aHR=0.348; 95% CI=0.184-0.658; p=0.001) datasets. The aHR of intention-to-treat OLA for recurrence decreased with increasing proportions of OLA users. No differences in overall survival were observed between the BEV and OLA intent groups, and between the BEV and OLA users. Compared to BEV, intention-to-treat OLA and actual use of OLA maintenance therapy were significantly associated with decreased disease recurrence risk in patients with
Discrepancy between Cytology and Histology in Cervical Cancer Screening: a Multicenter Retrospective Study (KGOG 1040)
Cervical cancer is the fourth common cancer in women worldwide. The Papanicolau test is the primary screening procedure to detect abnormal cervical cells. Colposcopy is the main procedure for discriminating high-grade cervical lesions. The study aimed at clarifying the discrepancy between cervical cytology and colposcopic biopsy histology as well as confounding factors. Eligible patients visited thirteen tertiary hospitals for colposcopic biopsy following cervical cytology and human papillomavirus (HPV) genotypes between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected. In our study, 3,798 eligible patients were included. Mean age of patients was 42.7 (19-88) years and mean BMI was 22.5 (16.9-34.1) kg/m². The referred cervical cytologic findings consisted of 495 normal, 1,390 atypical squamous cells of undetermined significance, 380 atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion, 792 low-grade squamous intraepithelial lesion, 593 high-grade squamous intraepithelial lesion, 79 atypical glandular cells, 46 squamous cell carcinoma, and 23 adenocarcinoma. HPV-positive findings were found in 3,008 (79.2%) patients and were not detected in 914 (24.1%) cases. The risk of unexpected low-grade lesions from histology was higher in patients > 45 years (odds ratio [OR], 2.137; 95% confidence intervals [CIs], 1.475-3.096). In contrast, the risk of unexpected high-grade lesions from colposcopic biopsy was lower in patients ≥ 45 years (OR, 0.530; 95% CI, 0.367-0.747) and HPV 16/18 infection was higher than other HPV (OR, 1.848; 95% CI, 1.385-2.469). Age and HPV genotypes were responsible for the discrepancies between cytology and histology. Precautions should be taken for women over the age of 45 in triage for colposcopy in order to avoid unnecessary testing.
Comparative performance of various human papillomavirus assays available in Korea for detecting cervical intraepithelial neoplasia
AbstractAimThe aim of this study was to evaluate the clinical performance for detecting cervical intraepithelial neoplasia (CIN) 2 or higher lesions among available human papillomavirus infection (HPV) genotyping tests in Korea.MethodsEligible patients visited 13 tertiary hospitals for colposcopic biopsy following cervical cytology and HPV genotyping test between January and December 2018. Baseline characteristics including age, body mass index (BMI), and parity were collected from 3798 patients. The performance of the Roche Cobas HPV 4800 was evaluated against other domestic HPV assays to detect CIN2 or higher.ResultsA total of seven types of HPV genotyping tests were analyzed in the research institutes. A total of 1358 patients (35.8%) tested Anyplex II HPV 28 and 701 patients (18.5%) tested Cobas 4800 HPV. The overall sensitivity in the detection of CIN2 or higher was 41.5% (38.9–44.1) in patients positive for HPV 16/18.The Cobas test for HPV 16/18 was concordant with other assays evaluated for detection of CIN2 or higher and showed sensitivity of 46.6%, which was not significantly different from other assays. Although Anyplex II HPV28 (Seegene) showed slightly decreased sensitivity for detecting CIN2 or higher lesion with HPV 16/18 positive (39.8%, p < 0.05) compared to Cobas 4800, in aspect of high‐risk HPV positive, Anyplex II HPV28 showed increased sensitivity (96.9%, p < 0.05).ConclusionThe performance of the HPV genotype test that were commonly used in Korea was concordant with Cobas HPV test. Further studies are needed to evaluate the safety, efficiency, and cost‐effectiveness of the various commercially available domestic HPV assays.
