Atezolizumab plus bevacizumab and chemotherapy for metastatic, persistent, or recurrent cervical cancer (BEATcc): a randomised, open-label, phase 3 trial.

BACKGROUND: The GOG240 trial established bevacizumab with chemotherapy as standard first-line therapy for metastatic or recurrent cervical cancer. In the BEATcc trial (ENGOT-Cx10-GEICO 68-C-JGOG1084-GOG-3030), we aimed to evaluate the addition of an immune checkpoint inhibitor to this standard backbone. METHODS: In this investigator-initiated, randomised, open-label, phase 3 trial, patients from 92 sites in Europe, Japan, and the USA with metastatic (stage IVB), persistent, or recurrent cervical cancer that was measurable, previously untreated, and not amenable to curative surgery or radiation were randomly assigned 1:1 to receive standard therapy (cisplatin 50 mg/m2 or carboplatin area under the curve of 5, paclitaxel 175 mg/m2, and bevacizumab 15 mg/kg, all on day 1 of every 3-week cycle) with or without atezolizumab 1200 mg. Treatment was continued until disease progression, unacceptable toxicity, patient withdrawal, or death. Stratification factors were previous concomitant chemoradiation (yes vs no), histology (squamous cell carcinoma vs adenocarcinoma including adenosquamous carcinoma), and platinum backbone (cisplatin vs carboplatin). Dual primary endpoints were investigator-assessed progression-free survival according to Response Evaluation Criteria in Solid Tumours version 1.1 and overall survival analysed in the intention-to-treat population. This study is registered with ClinicalTrials.gov, NCT03556839, and is ongoing. FINDINGS: Between Oct 8, 2018, and Aug 20, 2021, 410 of 519 patients assessed for eligibility were enrolled. Median progression-free survival was 13·7 months (95% CI 12·3-16·6) with atezolizumab and 10·4 months (9·7-11·7) with standard therapy (hazard ratio [HR]=0·62 [95% CI 0·49-0·78]; p<0·0001); at the interim overall survival analysis, median overall survival was 32·1 months (95% CI 25·3-36·8) versus 22·8 months (20·3-28·0), respectively (HR 0·68 [95% CI 0·52-0·88]; p=0·0046). Grade 3 or worse adverse events occurred in 79% of patients in the experimental group and in 75% of patients in the standard group. Grade 1-2 diarrhoea, arthralgia, pyrexia, and rash were increased with atezolizumab. INTERPRETATION: Adding atezolizumab to a standard bevacizumab plus platinum regimen for metastatic, persistent, or recurrent cervical cancer significantly improves progression-free and overall survival and should be considered as a new first-line therapy option.

Top advances of the year: Cervical cancer.

The year 2023 was an extraordinary year for the further development and expansion of novel treatments for all patients with cervical cancer, ranging from early stage to later stage and metastatic or recurrent disease. Individuals with early-stage disease will benefit from less invasive surgery with subsequent improvement in quality of life. The effectiveness of immunotherapy has been demonstrated in upfront, locally advanced cervical cancer and confirmed in advanced metastatic disease. Induction chemotherapy will play a role in some patients with locally advanced disease, particularly those in low resource areas of the world. Novel therapeutics including antibody-drug conjugates have shown efficacy even in pretreated patients. As we continue to explore innovative therapeutics in this space, however, we must also continue to improve the diversity of clinical trial accrual to allow for generalizable results. At the same time, we must focus on eradicating this disease with appropriate screening and vaccination.

Predictors of Blood Transfusion in Patients Undergoing Cytoreductive Surgeries for Ovarian Malignancy.

OBJECTIVES: The aims of this study were to describe the baseline estimated blood loss (EBL) in surgery and transfusion rate in patients undergoing cytoreductive surgeries for ovarian malignancy, and identify perioperative variables associated with blood loss and transfusion. METHODS: A retrospective cohort study at a single institution was performed that included patients with known or suspected ovarian malignancy undergoing cytoreductive surgery between 2016 and 2021. t tests, χ2 tests, and multiple logistic regression analyses were used. RESULTS: Among 44 patients meeting inclusion criteria, 61% received perioperative blood transfusion. There were significant differences in EBL and preoperative hemoglobin levels between patients who did and did not receive transfusion (EBL 442.6 vs 236.8 mL, P = 0.0008; preoperative hemoglobin 10.2 vs 11.2 g/dL, P = 0.049). After adjusting for preoperative hemoglobin, the risk of transfusion increased for each additional 200 mL of EBL (odds ratio [OR] 3.8, 95% confidence interval [CI] 1.5-9.5). Stratified by race, the association between EBL and transfusion risk remained statistically significant only for non-Latinx White patients (OR 6.1, 95% CI 1.7-21.9), who made up 77% of the study population, but not for patients of other races and ethnicities (OR 1.0, 95% CI 0.16-6.42). CONCLUSIONS: Perioperative blood transfusion is common in patients undergoing cytoreductive surgery. In this study, EBL and preoperative hemoglobin levels were significantly associated with transfusion receipt. Clinicians should optimize hemoglobin levels and intraoperative blood conservation strategies to reduce the need for transfusion. The results also highlight the importance of considering racial and ethnic differences when developing strategies to reduce transfusion risk.

Cervical cancer treatment update: A Society of Gynecologic Oncology clinical practice statement.

Cervical cancer is the most commonly diagnosed gynecologic cancer worldwide. Although the incidence has declined with increased screening and higher uptake of human papillomavirus (HPV) vaccination in high-income countries, this disease remains the second highest cause of cancer mortality among women in low- and middle-income countries. In this clinical practice statement, we describe therapies for cervical cancer by treatment setting, as well as quality of life, financial toxicity, and disparities associated with this disease. In addition to chemotherapy and radiation, therapeutic strategies for cervical cancer include immune checkpoint blockade, antiangiogenics, and antibody-drug conjugates. Optimal treatment for recurrent cervical cancer remains an area of unmet need, necessitating further exploration of rational and innovative treatment approaches, including cell and immune-based therapies. Importantly, development of effective therapies for cervical cancer must incorporate strategies to ensure universal equitable access to HPV vaccination, screening, and treatment. Important consequences of the disease and treatment that impact quality of life must also be addressed. Patients with cervical cancer are at increased risk for financial toxicity, which can lead to downstream detrimental effects on physical, financial, and career outcomes. Underrepresentation of racial and ethnic minorities in gynecologic oncology clinical trials highlights the urgent need for collaborative and focused initiatives to bridge the significant divide and alleviate inequalities in the prevention and treatment of cervical cancer.

Niraparib and dostarlimab for the treatment of recurrent platinum-resistant ovarian cancer: results of a Phase II study (MOONSTONE/GOG-3032).

OBJECTIVE: This study assessed the efficacy, safety, and health-related quality of life (HRQoL) of the treatment regimen of dostarlimab, a programmed death-1 inhibitor, combined with niraparib, a poly (ADP-ribose) polymerase inhibitor, in patients with BRCA wild type (BRCAwt) recurrent platinum-resistant ovarian cancer (PROC) who had previously received bevacizumab treatment. METHODS: This Phase II, open-label, single-arm, multicenter study, conducted in the USA, enrolled patients with recurrent PROC to receive niraparib and dostarlimab until disease progression or unacceptable toxicity (up to 3 years). A preplanned interim futility analysis was performed after the first 41 patients had undergone ≥1 radiographic evaluation (approximately 9 weeks from the first treatment). RESULTS: The prespecified interim futility criterion was met and the study was therefore terminated. For the 41 patients assessed, the objective response rate (ORR) was 7.3% (95% confidence interval: 1.5-19.9); no patients achieved a complete response, 3 patients (7.3%) achieved a partial response (duration of response; 3.0, 3.8, and 9.2 months, respectively), and 9 patients (22.0%) had stable disease. In total, 39 patients (95.1%) experienced a treatment-related adverse event, but no new safety issues were observed. HRQoL, assessed using FOSI, or Functional Assessment of Cancer Therapy - Ovarian Symptom Index scores, worsened over time compared with baseline scores. CONCLUSIONS: The study was terminated due to the observed ORR at the interim futility analysis. This highlights a need for effective therapies in treating patients with recurrent BRCAwt PROC.

Chemotherapy with or without avelumab followed by avelumab maintenance versus chemotherapy alone in patients with previously untreated epithelial ovarian cancer (JAVELIN Ovarian 100): an open-label, randomised, phase 3 trial.

BACKGROUND: Although most patients with epithelial ovarian cancer respond to frontline platinum-based chemotherapy, around 70% will relapse within 3 years. The phase 3 JAVELIN Ovarian 100 trial compared avelumab (anti-PD-L1 monoclonal antibody) in combination with chemotherapy followed by avelumab maintenance, or chemotherapy followed by avelumab maintenance, versus chemotherapy alone in patients with treatment-naive epithelial ovarian cancer. METHODS: JAVELIN Ovarian 100 was a global, open-label, three-arm, parallel, randomised, phase 3 trial run at 159 hospitals and cancer treatment centres in 25 countries. Eligible women were aged 18 years and older with stage III-IV epithelial ovarian, fallopian tube, or peritoneal cancer (following debulking surgery, or candidates for neoadjuvant chemotherapy), and had an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (1:1:1) via interactive response technology to receive chemotherapy (six cycles; carboplatin dosed at an area under the serum-concentration-time curve of 5 or 6 intravenously every 3 weeks plus paclitaxel 175 mg/m2 every 3 weeks or 80 mg/m2 once a week [investigators' choice]) followed by avelumab maintenance (10 mg/kg intravenously every 2 weeks; avelumab maintenance group); chemotherapy plus avelumab (10 mg/kg intravenously every 3 weeks) followed by avelumab maintenance (avelumab combination group); or chemotherapy followed by observation (control group). Randomisation was in permuted blocks of size six and stratified by paclitaxel regimen and resection status. Patients and investigators were masked to assignment to the two chemotherapy groups without avelumab at the time of randomisation until completion of the chemotherapy phase. The primary endpoint was progression-free survival assessed by blinded independent central review in all randomly assigned patients (analysed by intention to treat). Safety was analysed in all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, NCT02718417. The trial was fully enrolled and terminated at interim analysis due to futility, and efficacy is no longer being assessed. FINDINGS: Between May 19, 2016 and Jan 23, 2018, 998 patients were randomly assigned (avelumab maintenance n=332, avelumab combination n=331, and control n=335). At the planned interim analysis (data cutoff Sept 7, 2018), prespecified futility boundaries were crossed for the progression-free survival analysis, and the trial was stopped as recommended by the independent data monitoring committee and endorsed by the protocol steering committee. Median follow-up for progression-free survival for all patients was 10·8 months (IQR 7·1-14·9); 11·1 months (7·0-15·3) for the avelumab maintenance group, 11·0 months (7·4-14·5) for the avelumab combination group, and 10·2 months (6·7-14·0) for the control group. Median progression-free survival was 16·8 months (95% CI 13·5-not estimable [NE]) with avelumab maintenance, 18·1 months (14·8-NE) with avelumab combination treatment, and NE (18·2 months-NE) with control treatment. The stratified hazard ratio for progression-free survival was 1·43 (95% CI 1·05-1·95; one-sided p=0·99) with the avelumab maintenance regimen and 1·14 (0·83-1·56; one-sided p=0·79) with the avelumab combination regimen, versus control treatment. The most common grade 3-4 adverse events were anaemia (69 [21%] patients in the avelumab maintenance group, 63 [19%] in the avelumab combination group, and 53 [16%] in the control group), neutropenia (91 [28%], 99 [30%], and 88 [26%]), and neutrophil count decrease (49 [15%], 45 [14%], and 59 [18%]). Serious adverse events of any grade occurred in 92 (28%) patients in the avelumab maintenance group, 118 (36%) in the avelumab combination group, and 64 (19%) in the control group. Treatment-related deaths occurred in one (<1%) patient in the avelumab maintenance group (due to atrial fibrillation) and one (<1%) patient in the avelumab combination group (due to disease progression). INTERPRETATION: Although no new safety signals were observed, results do not support the use of avelumab in the frontline treatment setting. Alternative treatment regimens are needed to improve outcomes in patients with advanced epithelial ovarian cancer. FUNDING: Pfizer and Merck KGaA, Darmstadt, Germany.

Efficacy and safety of tisotumab vedotin in previously treated recurrent or metastatic cervical cancer (innovaTV 204/GOG-3023/ENGOT-cx6): a multicentre, open-label, single-arm, phase 2 study.

BACKGROUND: Few effective second-line treatments exist for women with recurrent or metastatic cervical cancer. Accordingly, we aimed to evaluate the efficacy and safety of tisotumab vedotin, a tissue factor-directed antibody-drug conjugate, in this patient population. METHODS: This multicentre, open-label, single-arm, phase 2 study was done across 35 academic centres, hospitals, and community practices in Europe and the USA. The study included patients aged 18 years or older who had recurrent or metastatic squamous cell, adenocarcinoma, or adenosquamous cervical cancer; disease progression on or after doublet chemotherapy with bevacizumab (if eligible by local standards); who had received two or fewer previous systemic regimens for recurrent or metastatic disease; had measurable disease based on Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1); and had an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients received 2·0 mg/kg (up to a maximum of 200 mg) tisotumab vedotin intravenously once every 3 weeks until disease progression (determined by the independent review committee) or unacceptable toxicity. The primary endpoint was confirmed objective response rate based on RECIST (version 1.1), as assessed by the independent review committee. Activity and safety analyses were done in patients who received at least one dose of the drug. This study is ongoing with recruitment completed and is registered with ClinicalTrials.gov, NCT03438396. FINDINGS: 102 patients were enrolled between June 12, 2018, and April 11, 2019; 101 patients received at least one dose of tisotumab vedotin. Median follow-up at the time of analysis was 10·0 months (IQR 6·1-13·0). The confirmed objective response rate was 24% (95% CI 16-33), with seven (7%) complete responses and 17 (17%) partial responses. The most common treatment-related adverse events included alopecia (38 [38%] of 101 patients), epistaxis (30 [30%]), nausea (27 [27%]), conjunctivitis (26 [26%]), fatigue (26 [26%]), and dry eye (23 [23%]). Grade 3 or worse treatment-related adverse events were reported in 28 (28%) patients and included neutropenia (three [3%] patients), fatigue (two [2%]), ulcerative keratitis (two [2%]), and peripheral neuropathies (two [2%] each with sensory, motor, sensorimotor, and neuropathy peripheral). Serious treatment-related adverse events occurred in 13 (13%) patients, the most common of which included peripheral sensorimotor neuropathy (two [2%] patients) and pyrexia (two [2%]). One death due to septic shock was considered by the investigator to be related to therapy. Three deaths unrelated to treatment were reported, including one case of ileus and two unknown causes. INTERPRETATION: Tisotumab vedotin showed clinically meaningful and durable antitumour activity with a manageable and tolerable safety profile in women with previously treated recurrent or metastatic cervical cancer. Given the poor prognosis for this patient population and the low activity of current therapies in this setting, tisotumab vedotin, if approved, would represent a new treatment for women with recurrent or metastatic cervical cancer.

The GOG partners: A program for industry sponsored clinical trials in gynecologic oncology within the GOG foundation.

The GOG Foundation, Inc. (GOG-F) is a non-profit 501(c)(3) organization with the purpose of promoting excellence in the quality and integrity of clinical and basic scientific research in the field of gynecologic malignancies. GOG Partners (GOG-P) is a program of the GOG-F and is positioned alongside NRG Oncology under the GOG-F organizational umbrella. GOG-P operates outside of the federally funded NCI NRG Oncology, a key distinguishing feature. By functioning as a site management organization (SMO), GOG-P provides an additional platform for clinical trial development, mentorship opportunities, patient accrual, and site infrastructure support yielding an expanded gynecologic oncology clinical trials infrastructure in the US. GOG-P has a consistent track record of conducting high quality clinical trials that lead to bringing novel FDA approved treatments for gynecologic cancer. This manuscript summarizes the history and organizational structure of the GOG-P. In addition, we outline the other key supportive programs within the GOG-F that help support the GOG-P effort to perform transformative gynecologic cancer research.

Phase II study of the safety and efficacy of the anti-PD-1 antibody balstilimab in patients with recurrent and/or metastatic cervical cancer.

OBJECTIVE: This phase II clinical trial evaluated the safety and antitumor activity of balstilimab, an anti-PD-1 antibody, in patients with previously-treated, recurrent/metastatic cervical cancer. METHODS: Eligible patients were 18 years or older with recurrent and/or metastatic cervical cancer and who had relapsed after a prior platinum-based treatment regimen for advanced disease. Balstilimab was administered intravenously at 3 mg/kg once every two weeks, for up to 24 months. The primary endpoint was objective response rate (ORR, RECIST v1.1) as assessed by an independent review committee. RESULTS: At data cutoff, 161 women (median age, 53 years [range 25-81]) were enrolled and treated with balstilimab. Of these, 140 had measurable disease at baseline and one prior line of platinum-based therapy in the metastatic, persistent, or recurrent setting; these patients were included in the efficacy analyses. The ORR was 15% (95% CI, 10.0%-21.8%) and included 5 patients with a complete response and 16 with a partial response. The median duration of response was 15.4 months. In patients with PD-L1-positive tumors the ORR was 20%, however patients with PD-L1-negative tumors also responded to balstilimab (ORR, 7.9%). Responses were not restricted to tumors of squamous cell histology, and an ORR of 12.5% was seen in the subset of patients with cervical adenocarcinoma. The disease control rate was 49.3% (95% CI, 41.1%-57.5%). Immune-mediated enterocolitis (3.1%) and diarrhea (1.9%) were the most common grade 3 or higher treatment-related adverse events. CONCLUSION: Balstilimab demonstrated meaningful and durable clinical activity, with manageable safety, in patients with previously-treated, recurrent/metastatic cervical cancer.

RaPiDS (GOG-3028): randomized Phase II study of balstilimab alone or in combination with zalifrelimab in cervical cancer.

Balstilimab (anti-programmed death 1) and zalifrelimab (anti-CTLA-4) are two new checkpoint inhibitors that have emerged as promising investigational agents for the treatment of cervical cancer, particularly in the setting of previously-treated, recurrent/metastatic disease. Here we describe the rationale and design of RaPiDS (NCT03894215), a two-arm Phase II study evaluating the safety, tolerability and efficacy of balstilimab administered alone or in combination with zalifrelimab in patients with advanced cervical cancer who progressed after first-line, platinum-based chemotherapy. Patients will be randomized in a 1:1 ratio. The primary end point is objective response rate, and key secondary objectives include safety, duration of response, progression-free survival, overall survival and quality of life outcomes.

Lay abstract Current treatment options for women with recurrent/metastatic cervical cancer are limited. Immunotherapy is altering the therapeutic landscape in this setting yet opportunities remain to improve on current outcomes. Dual blockade of different immune checkpoints is an approach shown to be highly effective in other cancers. Balstilimab (anti-programmed death 1) and zalifrelimab (anti-CTLA-4) are two new checkpoint inhibitors showing promise in patients with advanced cervical cancer. The RaPiDS trial is designed to characterize the safety and activity of balstilimab, alone and in combination with zalifrelimab, in patients with recurrent/metastatic cervical cancer who progressed after prior platinum-based chemotherapy. Clinical trial registration: NCT03894215 (ClinicalTrials.gov).

Bevacizumab plus fosbretabulin in recurrent ovarian cancer: Overall survival and exploratory analyses of a randomized phase II NRG oncology/gynecologic oncology group study.

OBJECTIVE: To explore the relationship between tumor size and response to combined anti-vascular targeted therapy using the anti-angiogenesis inhibitor, bevacizumab, and the tubulin-binding vascular disrupting agent, fosbretabulin. METHODS: An exploratory, post-hoc analysis of the randomized phase II trial, Gynecologic Oncology Group-0186I, was performed. One hundred and seven patients with recurrent ovarian carcinoma, treated with up to 3 prior regimens, were randomized to bevacizumab 15 mg/kg body weight with or without intravenous fosbretabulin 60 mg/m2 body surface area every 21 days until progression or unacceptable toxicity. The primary analysis favored the combination (HR 0.69; 95% CI, 0.47-1.00; p = .049) [Monk BJ, et al. J Clin Oncol 2016;34:2279-86]. The Cox proportional hazards model was used to estimate the treatment effect in various subpopulations. RESULTS: With extended follow-up, the median PFS for bevacizumab plus fosbretabulin was 7.6  months as compared to 4.8  months with bevacizumab alone (HR 0.74; 90% CI, 0.54-1.02). Overall survival was similar in the experimental and control arms (25.2 vs 24.4 mos, respectively, HR 0.85; 90% CI, 0.59-1.22; p = .461). Eighty-one patients had measurable disease and median tumor size was 5.7  cm. In the ≤5.7  cm subgroup, the HR for progression or death was 0.77 (90% CI 0.45-1.31). Patients with tumors >5.7  cm (n = 40) had a HR for progression or death of 0.55; 90% CI, 0.32-0.96; p = .075). CONCLUSIONS: Although no significant survival benefit was observed, the trend showing a reduced HR for progression or death with increasing tumor size when fosbretabulin is added to bevacizumab compared to bevacizumab alone warrants further study.

Overexpression of enhance of Zeste homolog 2 (EZH2) in endometrial carcinoma: An NRG Oncology/Gynecologic Oncology Group Study.

OBJECTIVES: Enhancer of zeste homolog 2 (EZH2) is a histone methyl transferase that mediates epigenetic silencing of tumor suppressor genes. It is commonly over-expressed in several solid tumors and has been shown to be a prognostic biomarker. We investigated patterns of EZH2 expression in endometrial cancer. METHODS: Evaluation of EZH2 expression was completed on both early and advanced stage endometrioid adenocarcinoma tissues and a subset of matched normal mullerian tissue samples, from participants enrolled in Gynecologic Oncology Group (GOG) protocol 210, using real time reverse transcription polymerase chain reaction (RT-PCR) and western blot (WB) analysis. Non-parametric methods were used to assess differences in mRNA and protein expression respectively with known clinical/pathologic prognostic factors. Survival analysis was performed using techniques including Cox proportional hazards (PH) model to evaluate differences in progression free survival (PFS) and overall survival (OS) based on EZH2 expression. RESULTS: Eighty-seven patient samples were analyzed that included 60 tumors and 27 matched-normal tissue specimens. EZH2 mRNA (p < .0001) and protein expression (p < .0001) in tumor specimens were significantly higher than in matched-normal tissue. In primary tumors, EZH2 protein expression was associated with lympho-vascular space invasion (LVSI, p = .044), and EZH2 mRNA expression was associated with age (p = .037). Differences in EZH2 expression between primary tumors and matched normal tissue were not associated with other known clinical and pathologic factors. However, there did appear to be a trend toward decreased progression-free survival among patients with high EZH2 expression levels. CONCLUSIONS: Our results confirm the differential expression of EZH2 in uterine cancers compared to normal tissues. However, there were no statistically significant differences in survival associated with EZH2 expression in patients with endometrial cancer. NCT #: NCT00340808.

Niraparib in the treatment of previously treated advanced ovarian, fallopian tube or primary peritoneal cancer.

Homologous recombination deficiency is a critical biologic feature of ovarian cancer. This weakness in DNA damage repair relies on functional poly(ADP-ribose) polymerase. Niraparib is a poly(ADP-ribose) polymerase inhibitor, orally available and initially approved for maintenance therapy in women with ovarian cancer by the US FDA in 2017 and by the EMA in 2017 for the same indication. Ovarian cancer represents the most lethal of gynecologic malignancies. The efficacy of niraparib has changed the landscape of ovarian cancer treatment, but overall survival data is still to come. This review summarizes the data regarding niraparib mechanism of action, toxicities, single agent efficacy and novel combinations in ovarian cancer.

Prevalence and predictors of HIV screening in invasive cervical cancer: a 10 year cohort study.

BACKGROUND: Invasive cervical carcinoma is associated with a human immunodeficiency virus (HIV) prevalence of >0.1%, and screening is recommended and cost-effective for cancer populations exceeding this threshold. HIV status is also prognostic for cancer-specific survival, but compliance with HIV screening is poor in the USA and abroad. OBJECTIVES: This study aims to describe HIV screening practices in a US comprehensive cancer center. To guide quality improvement, we identify characteristics which may predict compliance with screening. STUDY DESIGN: Women treated for invasive cervical cancer from January 2007 to December 2017 were identified by local cancer registry and billing data. We assessed age, race, ethnicity, insurance status, histology, stage, pregnancy, drug use, and HIV testing status. Univariate logistical regression was performed to assess predictors of completed HIV screening. RESULTS: Of 492 eligible women, the cumulative screening rate was 7.6%. Race, ethnicity, histology, and funding source were not predictive of screening. Every 5 year increase in age was associated with a lower chance of screening (OR 0.86, p=0.015), as was earlier stage at diagnosis (OR 0.43, p=0.017). Pregnancy during, or antecedent to, invasive cervical cancer diagnosis was significantly more predictive of screening compliance (OR 10.57, p=0.0007). Only 8/492 (1.6%) women in the cohort were active or former drug users, but within this group HIV screening was performed more frequently (OR 22.7, p<0.0001). CONCLUSION: Despite US and international recommendations for HIV screening in AIDS-defining cancers, compliance remains low. In our centers, factors including earlier age, advanced stage, active pregnancy at diagnosis, and any drug use history were predictive of greater compliance with screening. These data will inform a tailored intervention to improve compliance with HIV screening in our population.

Ovarian Cancer Maintenance: Practice-Changing Data Calls for Changing Practice.

Staying current on the rapidly evolving therapeutic landscape in oncology is challenging for clinicians. This commentary discusses exciting practice­changing data specific to ovarian cancer.

A phase II, multicenter, open-label trial of OTL38 injection for the intra-operative imaging of folate receptor-alpha positive ovarian cancer.

PURPOSE: OTL38 is a folate-indole-cyanine green-like conjugate to folate receptor alpha (FRa). The objectives of this prospective trial were to assess the safety and efficacy (sensitivity and positive predictive value (PPV)) of OTL38 for intraoperative imaging during epithelial ovarian cancer surgery. METHODS: Patients with suspected ovarian cancer planned for cytoreductive surgery were eligible to receive OTL38. Near-infrared (NIR) imaging was used to visualize target lesions that were evaluated by two blinded pathologists. A modified intent to treat (mITT) population of lesions from all patients who received OTL38-NIR imaging, underwent surgery, and had at least one FRa + target lesion was used to determine sensitivity and PPV. Two generalized linear models, with and without random effects, were employed to estimate sensitivity and PPV. RESULTS: Forty-four patients were evaluated for safety, and 225 lesions from 29 patients (the mITT population) were evaluated for efficacy. When assuming no correlation of interlesional results within a patient, sensitivity was estimated at 85.93% (95% lower boundary CI = 81.19) and PPV at 88.14% (95% lower boundary CI = 83.59). When controlling for actual correlation of detection among multiple lesions within a single patient (a random effect), sensitivity was estimated at 97.97% (95% lower boundary CI = 87.75) and PPV at 94.93% (95% lower boundary CI = 86.13). A total of 48.3% [14/29, (95% CI 0.29-0.67)] of patients had at least one additional lesion detected by OTL38 alone. Eight patients had mild drug-related adverse events including infusion reaction, nausea, vomiting, and abdominal pain. CONCLUSIONS: OTL38-NIR was safe and efficacious in this phase II study regardless of folate expression levels and merits phase III evaluation.

It's time to warm up to hyperthermic intraperitoneal chemotherapy for patients with ovarian cancer.

The peritoneal spread of ovarian cancer makes it a potential target for hyperthermic intraperitoneal chemotherapy (HIPEC). Intraperitoneal delivery exposes the tumor to concentrations of cytotoxic drugs much greater than with intravenous delivery, and in vitro studies have also shown that combining hyperthermia and platinum leads to an additive cytotoxic effect. Pharmacokinetic analyses have confirmed very high concentrations of cytotoxic drugs in the peritoneal cavity, with minimal systemic exposure and toxicity. The majority of historical data evaluating HIPEC in ovarian cancer are based on retrospective research, which included heterogeneous groups of patients and drugs used for HIPEC. Recent publications on the findings of prospective studies, including the first randomized trial in which the only difference in intervention was the addition of HIPEC with cisplatin to interval debulking surgery in stage III patients, have shown a benefit in favor of HIPEC. Yet, a recent prospective study from Korea did not find a benefit. Opponents of HIPEC have cited higher rates of complications with this approach, yet most of the serious adverse events observed are likely related to the surgery itself, and are comparable to the rates reported in studies evaluating cytoreductive surgery without HIPEC. Findings from a recent randomized controlled trial showed no delays in initiation or completion of postoperative chemotherapy in patients treated with HIPEC. A growing body of evidence is indicating that it might be time to seriously consider HIPEC as a complementary treatment at the time of cytoreductive surgery for patients with advanced-stage ovarian cancer in the setting of an experienced center. Yet, more research is needed to identify the population of patients who gain the most benefit from this therapy.

Multi-disciplinary summit on genetics services for women with gynecologic cancers: A Society of Gynecologic Oncology White Paper.

OBJECTIVE: To assess current practice, advise minimum standards, and identify educational gaps relevant to genetic screening, counseling, and testing of women affected by gynecologic cancers. METHODS: The Society of Gynecologic Oncology (SGO) organized a multidisciplinary summit that included representatives from the American College of Obstetricians and Gynecologists (ACOG), the American Society Clinical Oncology (ASCO), the National Society of Genetic Counselors (NSGC), and patient advocacy groups, BrightPink and Facing our Risk of Cancer Empowered (FORCE). Three subject areas were discussed: care delivery models for genetic testing, barriers to genetic testing, and educational opportunities for providers of genetic testing. RESULTS: The group endorsed current SGO, National Comprehensive Cancer Network (NCCN), and NSGC genetic testing guidelines for women affected with ovarian, tubal, peritoneal cancers, or DNA mismatch repair deficient endometrial cancer. Three main areas of unmet need were identified: timely and universal genetic testing for women with ovarian, fallopian tube, and peritoneal cancers; education regarding minimum standards for genetic counseling and testing; and barriers to implementation of testing of both affected individuals as well as cascade testing of family members. Consensus building among all stakeholders resulted in an action plan to address gaps in education of gynecologic oncology providers and delivery of cancer genetics care.
