A systematic review of stage IVA cervical cancer treatment: Challenges in the management of an understudied group.

OBJECTIVE: Stage IVA patients comprise a small proportion of participants in cervical cancer trials, yet survival outcomes are disproportionately poor. We aim to perform a systematic review evaluating stage IVA cervical cancer. METHODS: This systematic review was completed via PRISMA 2020 guidelines using two databases. Inclusion criteria comprised Phase III trials (2004-2024) assessing stage IVA cervical cancer including patients by stage. Searches had MeSH terms: ((cervical cancer) AND (stage IVA) AND (locally advanced)). 761 were articles identified, including books, trials, reviews, and meta-analyses. Of the articles identified, 12 met inclusion criteria. RESULTS: A total of 133 (3.8% of study populations) stage IVA and 818 (40% of study populations) stage III-IVA cervical cancer patients were analyzed. Two studies (stage IVA n = 15; 3.1%) established cisplatin as chemoradiotherapy agent of choice, while one study (stage IVA n = 2; 1%) showed no benefit with cisplatin versus radiotherapy alone. Four studies (stage IVA n = 32; 3.6%; stages IIIB-IVA n = 220; 24%) found no benefit with adjuvant chemotherapy, with one analyzing stage IIIB-IVA patients (progression-free survival (PFS) hazard ratio (HR) = 0.84; 95% confidence interval (CI): 0.57-1.23). Three studies (stage IVA n = 71; 5%) found no benefit adding immunomodulator (stage IVA overall survival HR = 3.48; 95% CI: 0.52-23.29), hypoxic cell sensitizer, or immunotherapy (stage III-IVA PFS HR = 0.71; 95% CI: 0.49-1.03) to chemoradiotherapy. One study (stages III-IVA n = 598; 56%) found benefit adding immunotherapy to chemoradiotherapy (stage III-IVA PFS HR = 0.58; 95% CI: 0.42-0.8). One study (stage IVA n = 13; 3.5%) showed benefit with induction chemotherapy. CONCLUSION: Trials have not included substantial IVA patients to draw reasonable conclusions. Despite mixed results for immunotherapy, adjuvant chemotherapy, and induction chemotherapy, the exact benefit for stage IVA patients remains unknown. Future clinical trials should include a greater number of stage IVA cervical cancer patients and analyze them individually.

Cervicovaginal metabolome and tumor characteristics for endometrial cancer detection and risk stratification.

PURPOSE: Endometrial cancer is highly prevalent and lacking non-invasive diagnostic techniques. Diagnosis depends on histological investigation of biopsy samples. Serum biomarkers for endometrial cancer have lacked sensitivity and specificity. The objective of this study was to investigate the cervicovaginal environment to improve understanding of metabolic reprogramming related to endometrial cancer and identify potential biomarker candidates for non-invasive diagnostic and prognostic tests. EXPERIMENTAL DESIGN: Cervicovaginal lavages were collected from 192 participants with endometrial cancer (n=66) and non-malignant conditions (n=108), and global untargeted metabolomics was performed. Using the metabolite data (n=920), we completed a multivariate biomarker discovery analysis. RESULTS: We analyzed grade 1/2 endometrioid carcinoma (n=53) and other endometrial cancer subtypes (n=13) to identify shared and unique metabolic signatures between the subtypes. When compared to non-malignant conditions, downregulation of proline (p<0.0001), tryptophan (p<0.0001), and glutamate (p<0.0001) was found among both endometrial cancer groups, relating to key hallmarks of cancer including immune suppression and redox balance. Upregulation (q<0.05) of sphingolipids, fatty acids, and glycerophospholipids was observed in endometrial cancer in a type-specific manner. Furthermore, cervicovaginal metabolites related to tumor characteristics, including tumor size and myometrial invasion. CONCLUSIONS: Our findings provide insights into understanding the endometrial cancer metabolic landscape and improvement into diagnosis. The metabolic dysregulation described in this paper linked specific metabolites and pathophysiological mechanisms including cellular proliferation, energy supply, and invasion of neighbouring tissues. Furthermore, cervicovaginal metabolite levels related to tumor characteristics, which are used for risk stratification. Overall, development of non-invasive diagnostic can improve both the acceptability and accessibility of diagnosis.

The impact of varying levels of residual disease following cytoreductive surgery on survival outcomes in patients with ovarian cancer: a meta-analysis.

BACKGROUND: Residual disease following cytoreductive surgery in patients with ovarian cancer has been associated with poorer survival outcomes compared with no residual disease. We performed a meta-analysis to assess the impact of varying levels of residual disease status on survival outcomes in patients with ovarian cancer who have undergone primary cytoreductive surgery or interval cytoreductive surgery in the setting of new therapies for this disease. METHODS: Medline, Embase, and Cochrane databases (January 2011 - July 2020) and grey literature, bibliographic and key conference proceedings, were searched for eligible studies. Fixed and random-effects meta-analyses compared progression and survival by residual disease level across studies. Heterogeneity between comparisons was explored via type of surgery, disease stage, and type of adjuvant chemotherapy. RESULTS: Of 2832 database and 16 supplementary search articles screened, 50 studies were selected; most were observational studies. The meta-analysis showed that median progression-free survival and overall survival decreased progressively with increasing residual disease (residual disease categories of 0 cm, > 0-1 cm and > 1 cm). Compared with no residual disease, hazard ratios (HR) for disease progression increased with increasing residual disease category (1.75 [95% confidence interval: 1.42, 2.16] for residual disease > 0-1 cm and 2.14 [1.34, 3.39] for residual disease > 1 cm), and also for reduced survival (HR versus no residual disease, 1.75 [ 1.62, 1.90] for residual disease > 0-1 cm and 2.32 [1.97, 2.72] for residual disease > 1 cm). All comparisons were significant (p < 0.05). Subgroup analyses showed an association between residual disease and disease progression/reduced survival irrespective of type of surgery, disease stage, or type of adjuvant chemotherapy. CONCLUSIONS: This meta-analysis provided an update on the impact of residual disease following primary or interval cytoreductive surgery, and demonstrated that residual disease was still highly predictive of progression-free survival and overall survival in adults with ovarian cancer despite changes in ovarian cancer therapy over the last decade. Higher numerical categories of residual disease were associated with reduced survival than lower categories.

Health-related quality of life in patients with newly diagnosed advanced ovarian cancer treated with niraparib vs placebo: Results from the phase 3 randomized PRIMA/ENGOT-OV26/GOG-3012 trial.

OBJECTIVE: To assess patient-reported health-related quality of life (HRQoL) in patients with ovarian cancer (OC) who received niraparib as first-line maintenance therapy. METHODS: PRIMA/ENGOT-OV26/GOG-3012 (NCT02655016) enrolled patients with newly diagnosed advanced OC who responded to first-line platinum-based chemotherapy. Patients were randomized (2:1) to niraparib or placebo once daily in 28-day cycles until disease progression, intolerable toxicity, or death. HRQoL was assessed as a prespecified secondary end point using patient-reported responses to the European Organisation for Research and Treatment of Cancer QOL Questionnaire (EORTC QLQ-C30), the EORTC QLQ Ovarian Cancer Module (EORTC QLQ-OV28), the Functional Assessment of Cancer Therapy-Ovarian Symptom Index (FOSI), and EQ-5D-5L questionnaires. Assessments were collected at baseline and every 8 weeks (±7 days) for 56 weeks, beginning on cycle 1/day 1, then every 12 weeks (±7 days) thereafter while the patient received study treatment. RESULTS: Among trial participants (niraparib, n = 487; placebo, n = 246), PRO adherence exceeded 80% for all instruments across all cycles. Patients reported no decline over time in HRQoL measured via EORTC QLQ-C30 Global Health Status/QoL and FOSI overall scores. Scores for abdominal/gastrointestinal symptoms (EORTC QLQ-OV28) and nausea and vomiting, appetite loss, and constipation (EORTC QLQ-C30) were higher (worse symptoms) in niraparib-treated patients than placebo-treated patients; except for constipation, these differences resolved over time. Patients did not self-report any worsening from baseline of fatigue, headache, insomnia, or abdominal pain on questionnaires. CONCLUSIONS: Despite some early, largely transient increases in gastrointestinal symptoms, patients with OC treated with niraparib first-line maintenance therapy reported no worsening in overall HRQoL.

Cytochrome P450 inhibitor/inducer treatment patterns among patients in the United States with advanced ovarian cancer who were prescribed or were eligible for poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors in the first-line maintenance setting.

Poly(adenosine diphosphate [ADP]-ribose) polymerase inhibitors (PARPi) are metabolized either via carboxylesterase (niraparib) or cytochrome P450 (CYP) enzymes (olaparib and rucaparib). Patients with advanced epithelial ovarian cancer (aOC) who receive concomitant medication metabolized by the CYP system may be at risk of drug-drug interactions impacting PARPi efficacy and tolerability. This study investigated CYP inhibitor/inducer treatment patterns in the first-line maintenance (1Lm) setting for patients with aOC. This retrospective cohort study used de-identified databases of US patients with aOC. Eligible patients were aged ≥18 years, diagnosed with aOC between January 2015-March 2021, and received CYP inhibitors/inducers during 1Lm PARPi initiation or the eligibility window (90 days before to 120 days after first-line platinum-based therapy ended [index]). Patients were either prescribed 1Lm PARPi monotherapy (PARPi cohort) or were not prescribed any 1Lm therapy within 120 days post-index (PARPi-eligible cohort). Strong/moderate CYP inhibitors/inducers were defined as area under the plasma concentration-time curve ratio (AUCR) ≥2 or clearance ratio (CL) ≤0.5 (inhibitors), and AUCR ≤0.5 or CL ratio ≥2 (inducers). Of 1411 patients (median age 63), 158 were prescribed PARPis and 1253 were PARPi-eligible. Among the PARPi cohort, 46.2%, 48.7%, and 5.1% were prescribed niraparib, olaparib, and rucaparib, respectively. For patients prescribed olaparib or rucaparib, 42.4% also received strong and/or moderate CYP inhibitors/inducers. This real-world study indicated a considerable proportion of patients received strong and/or moderate CYP inhibitors/inducers and were prescribed PARPis metabolized by the CYP system. Understanding potential impacts of concomitant CYP inhibitors/inducers on PARPi efficacy and safety is warranted.

Health care services utilization in patients with ovarian cancer receiving PARP inhibitor maintenance treatment in a US community oncology setting.

OBJECTIVES: The objective of this study was to describe healthcare resource use (HCRU) in addition to treatment patterns and discontinuations, in patients with ovarian cancer (OC) initiating PARP inhibitor (PARPi) maintenance treatment in a US community oncology setting. METHODS: This was a retrospective study of patients with OC initiating PARPi monotherapy maintenance during 01/01/2017 to 06/30/2019 (followed until 12/31/2019). Patients aged ≥18 years at first diagnosis of OC with ≥2 visits within The US Oncology Network were included. Structured and chart review data as well as claims data were used to describe treatment patterns and HCRU. RESULTS: Of the 162 charts reviewed, the median age of patients was 66 years and 80% had stage III or IV disease at diagnosis. In the niraparib, rucaparib and olaparib groups, proportions of patients experiencing dose interruptions were 51%, 50%, and 28%, and discontinuations due to toxicity were 37%, 17% and 15%, respectively. Within the first 6 months, mean numbers of total claims were 43.5, 56.4, and 36.0 in the niraparib, rucaparib, and olaparib groups, and laboratory claims were 13.9, 19.4, and 15.6, respectively. Proportions of patients with hospitalizations (niraparib 40%, rucaparib 32%, olaparib 19%; p = 0.03), also differed as did emergency department visits (niraparib 37%, rucaparib 23%, olaparib 16%; p = 0.02). CONCLUSION: Despite patients initiating niraparib having higher rates of dose management events and toxicity-related discontinuations, outpatient and laboratory utilization were similar across all three PARPi. Adequate monitoring of these medications, with differing toxicities, should be emphasized to potentially decrease dose reductions and toxicities.

The power of hope: Views of Ovarian Cancer patients on how maintenance therapy Affects their Lives (VOCAL).

Aim: To assess maintenance preference and trade-offs for patients with advanced epithelial ovarian cancer. Methods: Patients completed a time trade-off exercise ranking five maintenance approaches. Patients' preferred approach was compared with alternatives to determine the progression-free time they would trade off to remain on their preferred approach. Results: Of 152 patients (median age 53 years, 68% White), 56% chose one of four maintenance medications, mostly to feel proactive and 44% chose active surveillance. Compared with their preferred approach, patients were willing to trade a mean progression-free time before switching of 2.3 months for once-daily oral medications, 3.2 months for twice-daily oral medications, 5.5 months for intravenous infusions every 3 weeks (iv. q3), 6.1 months for active surveillance and 7.5 months for iv. q3 and twice-daily oral. Conclusion: Findings highlight the importance of patients' awareness of all maintenance approaches and involving them in the decision-making process.

What is the article about? The VOCAL study looked at maintenance approach preferences of patients with advanced epithelial ovarian cancer. Maintenance approach refers to the methods used after a patient has completed their initial chemotherapy to prevent disease progression for as long as possible. US patients completed an online survey, ranking five different maintenance approaches: No medication (active surveillance); Once-daily oral medication (e.g. pills); Twice-daily oral medication; Medication by intravenous infusion every 3 weeks; Medication by intravenous infusion every 3 weeks and oral twice-daily. Patients were asked to assume the same time to disease progression for all five approaches and the same side effects for the four approaches involving medications (2­5). Each patient then indicated how much time to disease progression they were willing to trade off to remain on their preferred approach before switching to an alternative. What were the results? Overall, 152 patients completed the survey (median age: 53 years, 68% White). Most patients preferred a medication approach (56%, n = 85) to active surveillance (44%, n = 67). Of the 85 patients who preferred medication, 66% (n = 56) reported this was to feel proactive in preventing their cancer returning. Once-daily oral medication was the most acceptable alternative to the patients' preferred maintenance approach, given they were willing to trade the least 'disease-free' time (2.3 months) before accepting a switch. What do the results mean? Individual patient preferences vary, and healthcare professionals should work with patients to determine which approach is most appropriate for them.

Latest advances in immuno-oncology for endometrial cancer: single-agent and combination regimens.

PURPOSE OF REVIEW: The scope of immuno-oncology in endometrial cancer has changed rapidly in the last several years, requiring up-to-date knowledge for those who treat these patients. RECENT FINDINGS: This article will focus on molecular profiling, recent trials, and FDA approvals of targeted immuno-oncology medications in endometrial cancer. These include immune checkpoint inhibitors alone or with combination treatment. SUMMARY: The publication of the TCGA has led to significant focus on molecular subgroupings into POLEm, MMRd, NSMP, and p53m groups. For those patients with MMRd vs. MMRp tumors, there are indications for single agent immune checkpoint inhibitors with dostarlimab or pembrolizumab. For those with MMRp tumors, the addition of lenvatinib to pembrolizumab has proven clinical benefit. The recent publication of the RUBY and NRG-GY018 trials have shown clinical benefit in both subgroups with addition of immune checkpoint inhibitor to platinum-based chemotherapy. Now there is approval for use of dostarlimab in frontline chemotherapy and maintenance for advanced stage or recurrent endometrial cancer. Several upcoming trials investigating molecular subgroups from the TCGA are eagerly anticipated.

Preoperative quality of life at time of gynecologic surgery: considerations for postoperative management.

BACKGROUND: Patients presenting for gynecologic surgery are a heterogeneous group. Preoperative quality of life may be a useful tool to guide postoperative management. OBJECTIVE: This study aimed to examine the key drivers of preoperative quality of life to improve counseling and postoperative management. STUDY DESIGN: This study analyzed preoperative survey results from 154 participants using the following surveys: National Institutes of Health Toolbox Global Health v1.2, Gastrointestinal: Gas and Bloating v1.1 13a, Gastrointestinal: Diarrhea v1.0 6a, and Sexual Function and Satisfaction Brief Profile (Female) v2.0, Perceived Stress Scale, the Vaginal Assessment Scale, and the Vulvar Assessment Scale. Survey results in the form of T-scores were compared in patients with endometrial cancer and patients with benign gynecologic conditions using the Kruskal-Wallis test. The multivariate analysis was performed using linear regression to adjust the comparisons for age, body mass index, and comorbidity. RESULTS: Of the 154 patients, preoperative diagnosis was benign in 66% (n=102) and endometrial cancer in 34% (n=52). Patients with endometrial cancer were more likely to be older, non-White, in lower income brackets, have higher body mass index, and be postmenopausal (P<.05). Although preoperative global health scores were similar between benign and malignant cases (P>.05), when adjusted for age, the differences in global health quality of life between patients with benign gynecologic conditions and those with endometrial cancer became significant, because the endometrial cancer group was older than the benign group (P<.05). However, when adjusting for age, body mass index, and comorbidities (hypertension and diabetes), the differences were no longer significant (P>.05). Sexual interest was decreased in the patients with endometrial cancer both in the unadjusted and adjusted model; and vulvar complaints became significantly different between the groups when controlling for body mass index, age, and comorbidities (P<.05). CONCLUSION: Despite substantial differences in preoperative diagnosis, preoperative quality of life is highly influenced by age, body mass index, and comorbidities. Therefore, these factors should be explored in surgical outcomes and postoperative management trials.

Correlation between progression-free survival and overall survival in patients with ovarian cancer after cytoreductive surgery: a systematic literature review.

OBJECTIVES: This analysis aimed to better define the relationship between progression-free survival and overall survival in adult patients with ovarian cancer (including fallopian tube or primary peritoneal cancer) following primary cytoreductive surgery or interval cytoreductive surgery. METHODS: A systematic literature review was carried out across the Medline, Embase, and Cochrane Central databases on 7 July 2020 (date limits 1 January 2011 to 7 July 2020) to identify studies with the following eligibility criteria: clinical trials/observational studies including >200 patients with ovarian cancer aged ≥18 years, evaluating overall survival/progression-free survival following cytoreductive surgery by residual disease status in the United States, Europe, Japan, or China. Weighted linear regression models were used to assess any correlation between median progression-free survival and overall survival, and between logHR for progression-free survival and logHR for overall survival. Risk of bias was assessed for all included studies. RESULTS: Of the 50 studies reported, 43 were observational studies (41 retrospective and two prospective cohort studies), and seven were reporting for randomized clinical trials-of which four were retrospective data analyses. For analyses of the relationship between overall survival and progression-free survival, 21 studies were eligible. The weighted linear regression model showed a strong positive association between the two survival endpoints. Goodness-of-fit analysis measured the adjusted R2 as 0.84 (p<0.001); a positive association was also observed between logHRs for overall survival and progression-free survival in the included studies. CONCLUSIONS: Median progression-free survival was predictive of median overall survival. This correlation between progression-free survival and overall survival after primary treatment for ovarian cancer highlights the validity of progression-free survival as a primary endpoint. Observational studies contributed most data, with limited information on disease stage and histology.

Factors Associated with Inpatient Narcotic Medication Usage after Robotic-assisted Laparoscopy.

STUDY OBJECTIVE: Describe factors that contribute to an increased narcotic medication use after robotic-assisted laparoscopic (RAL) surgery. DESIGN: A retrospective cohort. SETTING: A teaching hospital. PATIENTS: All patients undergoing RAL surgery by gynecologist oncologists at St. Joseph's Hospital and Medical Center over a 3-year period. INTERVENTIONS: RAL by gynecologist oncologists. MEASUREMENTS AND MAIN RESULTS: Using retrospective chart review, patients who underwent RAL surgery from 2012 to 2015 in the division of gynecologic oncology were identified; 757 patients were eligible for inclusion in the study. Total narcotic use during the postoperative hospital stay was converted to oral morphine milligram equivalents (OME). Bivariate correlations of total OME narcotics to multiple variables were evaluated using Spearman's rho. The average age, body mass index, and length of stay were 53.76 years (17-92), 31.75 kg/m2 (17-56), and 1.56 days (range, 0-19), respectively. Increased OME correlated positively with body mass index (Spearman's rho = .077, p = .036), any intraoperative complication (Spearman's rho = .05, p = .886), any postoperative complication (Spearman's rho = .16, p <.0001), length of stay in days (Spearman's rho = .282, p <.0001), procedure time (Spearman's rho .023, p = .52), and total anesthesia time (Spearman's rho, .032). Total OME narcotics were correlated negatively with age of 65 years or older (Spearman's rho, -.144, p <.0001) and use of patient-controlled analgesia (Spearman's rho, -.185, p <.0001). CONCLUSION: Age younger than 65 years seems to be a predictor for increased requirement of total morphine equivalent medication after RAL surgery, whereas patient-controlled analgesia use had a negative association.

Robotic-assisted gynecologic surgery in an older population: A comparison study.

INTRODUCTION: Robotic-assisted surgery in select patients has been shown to result in less peri-operative morbidity. Few studies have explored the association of robotic-assisted gynecology oncology surgery complication rates and increasing age. Our objective was to evaluate the peri- and postoperative complication rates in patients age 65 years or above in minimally-invasive robotic gynecologic surgery. MATERIAL AND METHODS: We performed a retrospective review of data from 765 consecutive minimally-invasive robotic-assisted surgeries performed by high-volume gynecologic oncologists. The patients were divided into "younger" patients aged <65 years and "older" patients aged ≥65 years. The primary outcomes were intraoperative and postoperative complications. RESULTS: Of the 765 patients analyzed, 185 (24%) were ≥ 65. The intraoperative complication rate in patients <65 was 1.9% (11/580) versus 1.62% (3/185) in females ≥65 (p = 0.808). The postoperative complication rate in patients <65 was 15.5% (90/580) versus 22.7% (42/185) in females ≥65 (p = 0.328). We observed more post-operative complications with patients who had intraoperative complications compared to patients who developed post-operative complications without intraoperative complcations in our sample, but it was not statisticaly significant (OR = 2.78, p = 0.097). The average estimated blood loss was 137.5 ml (0-1000) for patients younger than 65 years and 134.81 ml (0-2200) in patients 65 years or older (p = 0.097). DISCUSSION: Robotic gynecologic oncology surgery is common. When performed by expert surgeons, complications are not associated with increasing age.

Dostarlimab for Primary Advanced or Recurrent Endometrial Cancer.

BACKGROUND: Dostarlimab is an immune-checkpoint inhibitor that targets the programmed cell death 1 receptor. The combination of chemotherapy and immunotherapy may have synergistic effects in the treatment of endometrial cancer. METHODS: We conducted a phase 3, global, double-blind, randomized, placebo-controlled trial. Eligible patients with primary advanced stage III or IV or first recurrent endometrial cancer were randomly assigned in a 1:1 ratio to receive either dostarlimab (500 mg) or placebo, plus carboplatin (area under the concentration-time curve, 5 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area), every 3 weeks (six cycles), followed by dostarlimab (1000 mg) or placebo every 6 weeks for up to 3 years. The primary end points were progression-free survival as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1, and overall survival. Safety was also assessed. RESULTS: Of the 494 patients who underwent randomization, 118 (23.9%) had mismatch repair-deficient (dMMR), microsatellite instability-high (MSI-H) tumors. In the dMMR-MSI-H population, estimated progression-free survival at 24 months was 61.4% (95% confidence interval [CI], 46.3 to 73.4) in the dostarlimab group and 15.7% (95% CI, 7.2 to 27.0) in the placebo group (hazard ratio for progression or death, 0.28; 95% CI, 0.16 to 0.50; P<0.001). In the overall population, progression-free survival at 24 months was 36.1% (95% CI, 29.3 to 42.9) in the dostarlimab group and 18.1% (95% CI, 13.0 to 23.9) in the placebo group (hazard ratio, 0.64; 95% CI, 0.51 to 0.80; P<0.001). Overall survival at 24 months was 71.3% (95% CI, 64.5 to 77.1) with dostarlimab and 56.0% (95% CI, 48.9 to 62.5) with placebo (hazard ratio for death, 0.64; 95% CI, 0.46 to 0.87). The most common adverse events that occurred or worsened during treatment were nausea (53.9% of the patients in the dostarlimab group and 45.9% of those in the placebo group), alopecia (53.5% and 50.0%), and fatigue (51.9% and 54.5%). Severe and serious adverse events were more frequent in the dostarlimab group than in the placebo group. CONCLUSIONS: Dostarlimab plus carboplatin-paclitaxel significantly increased progression-free survival among patients with primary advanced or recurrent endometrial cancer, with a substantial benefit in the dMMR-MSI-H population.

Protein biomarkers in cervicovaginal lavages for detection of endometrial cancer.

BACKGROUND: Rates of endometrial cancer (EC) are increasing. For a definitive diagnosis, women undergo various time-consuming and painful medical procedures, such as endometrial biopsy with or without hysteroscopy, and dilation and curettage, which may create a barrier to early detection and treatment, particularly for women with inadequate healthcare access. Thus, there is a need to develop robust EC diagnostics based on non- or minimally-invasive sampling. The objective of this study was to quantify a broad range of immuno-oncology proteins in cervicovaginal lavage (CVL) samples and investigate these proteins as predictive diagnostic biomarkers for EC. METHODS: One hundred ninety-two women undergoing hysterectomy for benign or malignant indications were enrolled in this cross-sectional study. Classification of women to four disease groups: benign conditions (n = 108), endometrial hyperplasia (n = 18), low-grade endometrioid carcinoma (n = 53) and other EC subtypes (n = 13) was based on histopathology of biopsy samples collected after the surgery. CVL samples were collected in the operating room during the standard-of-care hysterectomy procedure. Concentrations of 72 proteins in CVL samples were evaluated using multiplex immunoassays. Global protein profiles were assessed using principal component and hierarchical clustering analyses. The relationships between protein levels and disease groups and disease severity were determined using Spearman correlation, univariate and multivariate receiver operating characteristics, and logistic regression analyses. RESULTS: Women with EC and benign conditions exhibited distinctive cervicovaginal protein profiles. Several proteins in CVL samples (e.g., an immune checkpoint protein, TIM-3, growth factors, VEGF, TGF-α, and an anti-inflammatory cytokine, IL-10) discriminated EC from benign conditions, particularly, when tested in combinations with CA19-9, CA125, eotaxin, G-CSF, IL-6, MCP-1, MDC, MCP-3 and TRAIL (sensitivity of 86.1% and specificity of 87.9%). Furthermore, specific biomarkers (e.g., TIM-3, VEGF, TGF-α, TRAIL, MCP-3, IL-15, PD-L2, SCF) associated with histopathological tumor characteristics, including histological type and grade, tumor size, presence and depth of myometrial invasion or mismatch repair protein status, implying their potential utility for disease prognosis or monitoring therapies. CONCLUSIONS: This proof-of-principle study demonstrated that cervicovaginal sampling coupled with multiplex immunoassay technology can offer a minimally to non-invasive method for EC detection.

Quality-adjusted time without symptoms of disease or toxicity and quality-adjusted progression-free survival with niraparib maintenance in first-line ovarian cancer in the PRIMA trial.

Background: The PRIMA phase 3 trial showed niraparib significantly prolongs median progression-free survival (PFS) versus placebo in patients with advanced ovarian cancer (OC) responsive to first-line platinum-based chemotherapy, including those who had tumors with homologous recombination deficiency (HRd). This analysis of PRIMA examined the quality-adjusted PFS (QA-PFS) and quality-adjusted time without symptoms of disease or toxicity (Q-TWiST) of patients on maintenance niraparib versus placebo. Methods: Patients were randomized 2:1 to receive once-daily maintenance niraparib (n = 487) or placebo (n = 246). QA-PFS was defined as the PFS of patients adjusted for their health-related quality of life (HRQoL) prior to disease progression, measured using European Quality of Life Five-Dimension (EQ-5D) questionnaire index scores from the PRIMA trial. Q-TWiST was calculated by combining data on PFS, duration of symptomatic grade ⩾2 adverse events (fatigue or asthenia, nausea, vomiting, abdominal pain, and abdominal bloating) prior to disease progression, and EQ-5D index scores. Analyses used data collected up to the last date of PFS assessment (May 17, 2019). Results: The restricted mean QA-PFS was significantly longer with niraparib versus placebo in the HRd (n = 373) and overall intention-to-treat (ITT; n = 733) populations (mean gains of 6.5 [95% confidence interval; CI, 3.9-8.9] and 4.1 [95% CI, 2.2-5.8] months, respectively). There were also significant improvements in restricted mean Q-TWiST for niraparib versus placebo (mean gains of 5.9 [95% CI, 3.5-8.6] and 3.5 [95% CI, 1.7-5.6] months, respectively) in the HRd and ITT populations. Conclusions: In patients with advanced OC, first-line niraparib maintenance was associated with significant gains in QA-PFS and Q-TWiST versus placebo. These findings demonstrate that niraparib maintenance treatment is associated with a PFS improvement and that treatment benefit is maintained even when HRQoL and/or toxicity data are combined with PFS in a single measure. Trial registration: ClinicalTrials.gov: NCT02655016; trial registration date: January 13, 2016. Plain language summary: Background: In a large clinical trial called PRIMA, patients with advanced cancer of the ovary (ovarian cancer) were given either niraparib (a type of cancer medicine) or placebo (a pill containing no medicine/active substances) after having chemotherapy (another type of cancer medicine). Taking niraparib after chemotherapy is called maintenance therapy and aims to give patients more time before their cancer returns or gets worse than if they were not given any further treatment. In the PRIMA trial, patients who took niraparib did have more time before their cancer progressed than if they took placebo. However, it is important to consider patients' quality of life, which can be made worse by cancer symptoms and/or side effects of treatment. Here, we assessed the overall benefit of niraparib for patients in PRIMA.Methods: Both the length of time before disease progression (or survival time) and quality of life were considered using two different analyses:● The first analysis was called quality-adjusted PFS (QA-PFS) and looked at how long patients survived with good quality of life.● The second analysis was called quality-adjusted time without symptoms of disease or toxicity (Q-TWiST) and looked at how long patients survived without cancer symptoms or treatment side effects.Results: The PRIMA trial included 733 patients; 487 took niraparib and 246 took placebo. Around half of the patients in both groups had a type of ovarian cancer that responds particularly well to drugs like niraparib - they are known as homologous recombination deficiency (HRd) patients.● When information on quality of life (collected from patient questionnaires) and survival was combined in the QA-PFS analysis, HRd patients who took niraparib had approximately 6.5 months longer with a good quality of life before disease progression than those who took placebo. In the overall group of patients (including HRd patients and non-HRd patients), those who took niraparib had approximately 4 months longer than with placebo.● Using the second analysis (Q-TWiST) to combine information on survival with cancer symptoms and treatment side effects, the HRd patients taking niraparib had approximately 6 months longer without cancer symptoms or treatment side effects (such as nausea or vomiting) than patients taking placebo. In the overall group of patients, those taking niraparib had approximately 3.5 months longer without these cancer symptoms/side effects than patients receiving placebo.Conclusions: These results show that the survival benefits of niraparib treatment remain when accounting for patients' quality of life. These benefits were seen not only in HRd patients who are known to respond better to niraparib, but in the overall group of patients who took niraparib.

Impact of disease progression on health-related quality of life of advanced ovarian cancer patients - Pooled analysis from the PRIMA trial.

OBJECTIVE: Progression-free survival (PFS) is an important early efficacy endpoint in ovarian cancer (OC) and its relevance to patients should be assessed. PRIMA, a phase III trial, assessed niraparib in patients with OC; this post hoc analysis examined the relationship between disease progression in OC and health-related quality of life (HRQoL). METHODS: The PRIMA trial randomized patients with advanced OC responsive to first-line platinum-based chemotherapy to once daily maintenance oral niraparib or placebo. This post hoc analysis evaluated the impact of disease progression on HRQoL by comparing HRQoL at the last visit pre-progression to end of treatment (EoT), and after 4, 8, 12, and 24 weeks. Assessments included the Functional Assessment of Cancer Therapy-Ovarian Symptom Index (FOSI), the European Quality of Life Five Dimension Five Level questionnaire (EQ-5D-5L) and EQ Visual Analogue Scale (EQ-VAS), the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (EORTC-QLQ-C30), and the EORTC Quality of Life Questionnaire Ovarian Cancer module (EORTC-QLQ-OV28). RESULTS: This post hoc analysis included 733 patients. Mean FOSI, EQ-5D-5L, and EQ-VAS scores deteriorated from last visit pre-progression to EoT and remained low up to 24-week follow-up. Least squares mean changes from last visit pre-progression to EoT were -2.1 (95% confidence interval -2.4, -1.7) for FOSI, -4.6 (-5.6, -3.5) for the EQ-5D-5L index, and -7.9 (-9.6, -6.3) for EQ-VAS. CONCLUSIONS: Disease progression negatively impacted HRQoL in patients with OC. PFS is clinically relevant, and prolonging PFS may preserve HRQoL.

Cervicovaginal DNA Virome Alterations Are Associated with Genital Inflammation and Microbiota Composition.

While the link between the cervicovaginal bacterial microbiome, human papillomavirus (HPV) infection, and cervical cancer is recognized (P. Laniewski, D. Barnes, A. Goulder, H. Cui, et al., Sci.

Rep. 7:10200, 2017, http://dx.doi.org/10.1038/s41598-017-09842-6), the role of the cervicovaginal virome remains poorly understood. In this pilot study, we conducted metagenomic next-generation sequencing of cervicovaginal lavage specimens to investigate the relationship between the cervicovaginal DNA virome, bacterial microbiome, genital inflammation, and HPV infection. Specific virome alterations were associated with features of the local microenvironment related to HPV persistence and progression to cervical cancer. Cervicovaginal viromes clustered distinctly by genital inflammation state. Genital inflammation was associated with decreased virome richness and alpha diversity and an increased abundance of Anelloviridae species from the genus Alphatorquevirus. Lactobacillus bacteriophages were closely associated with increased Lactobacillus abundance, consistent with phage-host relationships. Interestingly, bacteria-bacteriophage transkingdom interactions were linked to genital inflammation and showed specific interactions with bacterial vaginosis-associated bacteria, including Gardnerella, Prevotella, and Sneathia. Taken together, our results reveal prominent virome interactions with features of the cervicovaginal microenvironment that are associated with HPV and cervical cancer. These findings expand our understanding of the cervicovaginal host-microbiome interactions in women's health. IMPORTANCE HPV infection is an established risk factor for cervical cancer. However, more broadly, the role of the cervicovaginal virome in cervical cancer progression is not well understood. Here, we identified cervicovaginal DNA virome alterations associated with local microenvironment factors (vaginal microbiota and genital inflammation) that influence HPV persistence and progression to cervical cancer. These findings indicate that the cervicovaginal virome plays an important role in women's health.

Multi-omics data integration reveals metabolome as the top predictor of the cervicovaginal microenvironment.

Emerging evidence suggests that host-microbe interaction in the cervicovaginal microenvironment contributes to cervical carcinogenesis, yet dissecting these complex interactions is challenging. Herein, we performed an integrated analysis of multiple "omics" datasets to develop predictive models of the cervicovaginal microenvironment and identify characteristic features of vaginal microbiome, genital inflammation and disease status. Microbiomes, vaginal pH, immunoproteomes and metabolomes were measured in cervicovaginal specimens collected from a cohort (n = 72) of Arizonan women with or without cervical neoplasm. Multi-omics integration methods, including neural networks (mmvec) and Random Forest supervised learning, were utilized to explore potential interactions and develop predictive models. Our integrated analyses revealed that immune and cancer biomarker concentrations were reliably predicted by Random Forest regressors trained on microbial and metabolic features, suggesting close correspondence between the vaginal microbiome, metabolome, and genital inflammation involved in cervical carcinogenesis. Furthermore, we show that features of the microbiome and host microenvironment, including metabolites, microbial taxa, and immune biomarkers are predictive of genital inflammation status, but only weakly to moderately predictive of cervical neoplastic disease status. Different feature classes were important for prediction of different phenotypes. Lipids (e.g. sphingolipids and long-chain unsaturated fatty acids) were strong predictors of genital inflammation, whereas predictions of vaginal microbiota and vaginal pH relied mostly on alterations in amino acid metabolism. Finally, we identified key immune biomarkers associated with the vaginal microbiota composition and vaginal pH (MIF), as well as genital inflammation (IL-6, IL-10, MIP-1α).

Implicit biases in healthcare: implications and future directions for gynecologic oncology.

Health disparities have been found among patients with gynecologic cancers, with the greatest differences arising among groups based on racial, ethnic, and socioeconomic factors. Although there may be multiple social barriers that can influence health disparities, another potential influence may stem from healthcare system factors that unconsciously perpetuate bias toward patients who are racially and socioeconomically disadvantaged. More recent research suggested that providers hold these implicit biases (automatic and unconscious attitudes) for stigmatized populations with cancer, with emerging evidence for patients with gynecologic cancer. These implicit biases may guide providers' communication and medical judgments, which, in turn, may influence the patient's satisfaction with and trust in the provider. This narrative review consolidated the current research on implicit bias in healthcare, with a specific emphasis on oncology professionals, and identified future areas of research for examining and changing implicit biases in the field of gynecologic oncology.
