Maximizing ovarian function and fertility following chemotherapy in premenopausal patients: Is there a role for ovarian suppression?

As more premenopausal patients undergo fertility preserving cancer treatments, there is an increased need for fertility counseling and ovarian sparing strategies. Many patients receive gonadotoxic chemotherapeutic agents which can put them at risk of primary ovarian insufficiency or profoundly diminished ovarian reserve. Traditionally, estradiol and follicle stimulating hormone (FSH) values have been used to evaluate ovarian function but more recently, reproductive endocrinologists have been proponents of anti-mullerian hormone (AMH) as a validated measure of ovarian potential. While the gold standard for fertility preservation remains oocyte cryopreservation, data suggest there may be additional interventions that can mitigate the gonadotoxic effects of chemotherapeutic agents. The main objectives of this focused review were to quantify the risk of primary ovarian failure associated with the most common chemotherapies used in treatment of gynecologic cancers and to evaluate and recommend potential interventions to mitigate toxic effects on ovarian function. Chemotherapeutic agents can cause direct loss of oocytes and primordial follicles as well as stromal and vascular atrophy and the extent is dependent upon mechanism of action and age of the patient. The risk of ovarian failure is the highest with alkylating agents (42.2 %), anthracyclines (<10-34 % in patients under 40 years versus 98 % in patients aged 40-49), taxanes (57.1 %) and platinum agents (50 %). Multiple trials demonstrate that gonadotropin releasing hormone (GnRH) agonists, when administered concurrently with chemotherapy, may have protective effects, with more patients experiencing resumption of a regular menstruation pattern and recovering ovarian function more quickly post-treatment. Premenopausal patients receiving chemotherapy for the treatment of gynecologic cancers should receive adequate counseling on the potential adverse effects on their fertility. Although oocyte cryopreservation remains the gold standard for fertility preservation, there is some evidence to suggest that GNRH agonists could help maintain and preserve ovarian function and should be considered.

Computational pathology identifies immune-mediated collagen disruption to predict clinical outcomes in gynecologic malignancies.

BACKGROUND: The role of immune cells in collagen degradation within the tumor microenvironment (TME) is unclear. Immune cells, particularly tumor-infiltrating lymphocytes (TILs), are known to alter the extracellular matrix, affecting cancer progression and patient survival. However, the quantitative evaluation of the immune modulatory impact on collagen architecture within the TME remains limited. METHODS: We introduce CollaTIL, a computational pathology method that quantitatively characterizes the immune-collagen relationship within the TME of gynecologic cancers, including high-grade serous ovarian (HGSOC), cervical squamous cell carcinoma (CSCC), and endometrial carcinomas. CollaTIL aims to investigate immune modulatory impact on collagen architecture within the TME, aiming to uncover the interplay between the immune system and tumor progression. RESULTS: We observe that an increased immune infiltrate is associated with chaotic collagen architecture and higher entropy, while immune sparse TME exhibits ordered collagen and lower entropy. Importantly, CollaTIL-associated features that stratify disease risk are linked with gene signatures corresponding to TCA-Cycle in CSCC, and amino acid metabolism, and macrophages in HGSOC. CONCLUSIONS: CollaTIL uncovers a relationship between immune infiltration and collagen structure in the TME of gynecologic cancers. Integrating CollaTIL with genomic analysis offers promising opportunities for future therapeutic strategies and enhanced prognostic assessments in gynecologic oncology.

The role of cells that are part of our immune system in altering the structure of the protein collagen within cancers is not fully understood, particularly within cancers that affect women such as ovarian, cervical and uterine cancers. Here, we developed a computer-based method called CollaTIL to explore how immune cells influence collagen in these tumors and affect their growth. We found that a higher presence of immune cells leads to less organized collagen in the tumor. Conversely, when there are fewer immune cells, the collagen tends to be more structured. Additionally, CollaTIL identifies patterns that predict patient outcomes in these cancers. These findings not only enhance our understanding of tumor biology but also may be useful in helping clinicians to predict which patients are at risk of their disease progressing.

Condyloma lata mimicking vulvar carcinoma in an immunocompromised patient: A case report.

Background: Syphilis is a sexually transmitted infection with increasing incidence in the United States. Presentations of syphilis vary widely and can be easily mistaken for other diagnoses, including cancer, especially in atypical cases. Case description: At her delivery after no prenatal care, a 35-year-old woman was found to have exophytic vulvar and perianal lesions, inguinal lymphadenopathy, and a new diagnosis of HIV, with a strong clinical concern for vulvar and/or anal carcinoma. She was subsequently diagnosed with presumed late latent syphilis and began weekly intramuscular penicillin G benzathine treatment. CT imaging demonstrated a perineal plaque-like area with bilateral inguinal, external iliac and retroperitoneal lymphadenopathy. She was seen in gynecologic oncology clinic one week after her initial presentation with notable improvement in the vulvar lesions, raising suspicion for condyloma lata rather than invasive or preinvasive disease on the vulva, however concern remained for dysplasia in the perianal lesion. Another week later, she underwent an exam under anesthesia with vulvar and perianal biopsies revealing chronic inflammation and granulomatous change without evidence of malignancy or dysplasia. At the four week post operative visit, there was almost complete resolution of the lesions. Conclusion: Syphilis should be considered in the differential diagnosis of atypical vulvar lesions.

Lifestyle intervention in ovarian cancer enhanced survival (LIVES) study (NRG/GOG0225): Recruitment, retention and baseline characteristics of a randomized trial of diet and physical activity in ovarian cancer survivors.

OBJECTIVE: The Lifestyle Intervention for oVarian cancer Enhanced Survival (LIVES) is a national study of a combined diet and physical activity intervention for stage II-IV ovarian cancer survival, an under-represented cancer in lifestyle behavioral intervention research. Here, we present the data on recruitment, retention, and baseline demographic, clinical and lifestyle behavior characteristics of the LIVES study participants. METHODS: The LIVES study (NRG Oncology/GOG 0225) is a Phase III diet plus physical activity intervention trial testing the hypothesis that ovarian cancer survivors in the lifestyle intervention will demonstrate better progression-free survival than those in the control condition. Study interventions were delivered via centralized telephone-based health coaching. Baseline descriptive statistics were computed for demographic, clinical, and lifestyle behavior characteristics. RESULTS: The LIVES study exceeded its recruitment goals, enrolling 1205 ovarian cancer survivors from 195 NRG/NCORP-affiliated oncology practices across 49 states from 2012 to 2018. The mean age of enrollees was 59.6 years; the majority (69.4%) with stage III disease; 89% White, 5.5% Hispanic; 64% overweight/obese. Baseline self-reported diet showed a mean daily intake of 6.6 servings of fruit and vegetables, 62.7 fat grams, and 21.7 g of fiber. Physical activity averaged 13.0 MET-hours/week of moderate to vigorous physical activity; 50.9 h/week of sedentary time. Retention rates exceeded 88%. CONCLUSION: The LIVES study demonstrates efficiency in recruiting and retaining ovarian cancer survivors in a 24-month study of diet and physical activity intervention with a primary endpoint of progression free survival that will be reported. TRIAL REGISTRATION: ClinicalTrials.govNCT00719303.

Society of Gynecologic Oncology Journal Club: Controversial conversations in gynecologic cancer - Navigating maintenance therapy for homologous recombinant proficient ovarian cancer.

The Society of Gynecologic Oncology (SGO) Journal Club is an open forum to review pertinent studies relevant to controversial topics in the management of gynecologic cancers. On August 3rd, 2022, SGO hosted a Journal Club focused on the role of maintenance therapy for homologous recombinant proficient (HRP) patients with ovarian cancer. Navigating optimal therapies has become more complex with the emergence of new clinical trial data and the evolving understanding of how to classify ovarian cancers as HRP. Our speakers, Drs. Susan Modesitt, Barbara Norquist and Rodney Rocconi presented Gynecologic Oncology Group (GOG) 218 (Burger et al., 2011), the VITAL Trial (Rocconi et al., 2021), and the PRIMA study (Gonzalez-Martin et al., 2019). We asked our experts to discuss their opinions and interpretations on the application of these data to current clinical practice. Poll questions were presented to the audience for a pre- and post-webinar comparison (Table 1). Results of the poll questions are shown in Table 1.

Endometrial Hyperplasia.

The objectives of this Clinical Expert Series on endometrial hyperplasia are to review the etiology and risk factors, histologic classification and subtypes, malignant progression risks, prevention options, and to outline both surgical and nonsurgical treatment options. Abnormal uterine and postmenopausal bleeding remain the hallmark of endometrial pathology, and up to 10-20% of postmenopausal bleeding will be either hyperplasia or cancer; thus, immediate evaluation of any abnormal bleeding with either tissue procurement for pathology or imaging should be undertaken. Although anyone with a uterus may develop atypical hyperplasia, also known as endometrial intraepithelial neoplasia (EIN), genetic predispositions (eg, Lynch syndrome), obesity, chronic anovulation, and polycystic ovarian syndrome all markedly increase these risks, whereas use of oral contraceptive pills or progesterone-containing intrauterine devices will decrease the risk. An EIN diagnosis carries a high risk of concomitant endometrial cancer or eventual progression to cancer in the absence of treatment. The definitive and curative treatment for EIN remains hysterectomy; however, the obesity epidemic, the potential desire for fertility-sparing treatments, the recognition of varying rates of malignant transformation, medical comorbidities, and an aging population all may factor into decisions to employ nonsurgical treatment modalities.

Optimizing post-operative opiate prescribing following gynecologic surgery.

Background: Post-operative opiate prescribing has traditionally been stratified by procedure type with little regard for patient opiate utilization. We sought to evaluate peri-operative factors associated with patient opiate utilization post-operatively to develop, implement, and assess a discharge prescribing intervention. Study design: This was a quality improvement study of opiate prescribing practices for patients undergoing gynecologic surgery on an enhanced recovery pathway (ERAS) pre- and post-discharge prescription intervention. In the pre-intervention cohort (12/2018 to 05/2019), peri-operative factors (demographic, procedure, and pain scores) associated with post-operative patient opiate usage and quantity of opiate prescribed were identified. A discharge planning intervention based solely on opiate usage was implemented. The pre- and post-intervention cohort (07/2020 to 09/2020) were compared to assess changes in post-operative opiate prescribing and refill requests. Results: There were 220 patients in the pre-intervention cohort and 120 patients post-intervention. Post-operative opiate usage in the pre-intervention cohort was correlated only with pain score and age (p < 0.001, p = 0.04). Quantity of opiate prescribed was correlated only with procedure type and not reflective of patient opiate usage. Using this information, a discharge planning intervention for opiate prescription informed by opiate usage in the twenty-four hours prior to discharge was added to the discharge order set. Post-intervention, adherence to recommended prescription was 40.8%. Opiate prescriptions decreased from a mean 27.3 tablets to 14.8 tablets (p < 0.001). Conclusions: A tailored, patient specific approach to post-operative opiate prescribing can significantly decrease the quantity of opiates prescribed.

Effect of risk-reducing salpingo-oophorectomy on sex steroid hormone serum levels among postmenopausal women: an NRG Oncology/Gynecologic Oncology Group study.

BACKGROUND: Risk-reducing salpingo-oophorectomy is an effective ovarian cancer risk reduction strategy. However, bilateral oophorectomy has also been associated with increased long-term nonneoplastic sequelae, effects suggested to be mediated through reductions in systemic sex steroid hormone levels. Currently, it is unclear whether the postmenopausal ovary contributes to the systemic hormonal milieu or whether postmenopausal ovarian volume or other factors, such as body mass index and age, affect systemic hormone levels. OBJECTIVE: We examined the impact of oophorectomy on sex steroid hormone levels in postmenopausal women. Furthermore, we explored how well ovarian volume measured by transvaginal ultrasound correlated with direct ovarian measures obtained during surgical pathology evaluation and investigated the association between hormone levels and ovarian volumes. STUDY DESIGN: Postmenopausal women who underwent risk-reducing salpingo-oophorectomy (180 cases) or ovarian cancer screening (38 controls) enrolled in an international, prospective study of risk-reducing salpingo-oophorectomy and risk of ovarian cancer algorithm-based screening among women at increased risk of ovarian cancer (Gynecologic Oncology Group-0199) were included in this analysis. Controls were frequency matched to the cases on age at menopause, age at study entry, and time interval between blood draws. Ovarian volume was calculated using measurements obtained from transvaginal ultrasound in both cases and controls and measurements recorded in surgical pathology reports from cases. Serum hormone levels of testosterone, androstenedione, androstenediol, dihydrotestosterone, androsterone, dehydroepiandrosterone, estrone, estradiol, and sex hormone-binding globulin were measured at baseline and follow-up. Spearman correlation coefficients were used to compare ovarian volumes as measured on transvaginal ultrasound and pathology examinations. Correlations between ovarian volumes by transvaginal ultrasound and measured hormone levels were examined using linear regression models. All models were adjusted for age. Paired t tests were performed to evaluate individual differences in hormone levels before and after risk-reducing salpingo-oophorectomy. RESULTS: Ovarian volumes measured by transvaginal ultrasound were only moderately correlated with those reported on pathology reports (Spearman rho [ρ]=0.42). The median time interval between risk-reducing salpingo-oophorectomy and follow-up for the cases was 13.3 months (range, 6.0-19.3), and the median time interval between baseline and follow-up for the controls was 12.7 months (range, 8.7-13.4). Sex steroid levels decreased with age but were not correlated with transvaginal ultrasound ovarian volume, body mass index, or time since menopause. Estradiol levels were significantly lower after risk-reducing salpingo-oophorectomy (percentage change, -61.9 post-risk-reducing salpingo-oophorectomy vs +15.2 in controls; P=.02), but no significant differences were seen for the other hormones. CONCLUSION: Ovarian volumes measured by transvaginal ultrasound were moderately correlated with volumes directly measured on pathology specimens and were not correlated with sex steroid hormone levels in postmenopausal women. Estradiol was the only hormone that declined significantly after risk-reducing salpingo-oophorectomy. Thus, it remains unclear whether the limited post-risk-reducing salpingo-oophorectomy changes in sex steroid hormones among postmenopausal women impact long-term adverse outcomes.

Beneficial effects of exercise on chemotherapy-induced peripheral neuropathy and sleep disturbance: A review of literature and proposed mechanisms.

The goal of this narrative review is to evaluate the literature regarding exercise training as a therapy to prevent or mitigate deleterious side effects of chemotherapy, specifically peripheral neuropathy and sleep disturbances and to make concrete recommendations for implementation for the practicing oncologist. A literature search was conducted for studies that included an exercise intervention to be implemented for patients undergoing or previously treated with chemotherapy along with an analysis of its effect on either chemotherapy-induced peripheral neuropathy (CIPN) or chemotherapy-induced sleep disturbances. Studies were subsequently analyzed and summarized in order to determine the overall promise of exercise as a therapy in this setting. Five studies met inclusion criteria to be assessed with regard to the effect of exercise on CIPN and eight were included for sleep disturbances. Exercise was found to be a significantly beneficial therapy in preventing, mitigating, or improving the symptoms of CIPN and sleep disturbances in cancer patients in the majority of studies evaluated. Exercise is an effective intervention and should be specifically prescribed concurrently with chemotherapy to maximize potential of avoiding these debilitating side effects, which significantly and negatively impact quality of life in cancer survivors.

MLH1/PMS2-deficient Endometrial Carcinomas in a Universally Screened Population: MLH1 Hypermethylation and Germline Mutation Status.

MLH1/PMS2 loss due to epigenetic hypermethylation of the MLH1 promoter is the most common cause of mismatch repair deficiency in endometrial carcinoma, and typically provides reassurance against an associated germline mutation. To further characterize the genetic features of MLH1/PMS2-deficient endometrial cancers, the departmental database was searched for cases with dual MLH1/PMS2 loss and retained MSH2/6 expression which underwent MLH1 hypermethylation testing. Genetic testing results were obtained when available. One hundred seventeen endometrial cancers met inclusion criteria: 100 (85%) were MLH1-hypermethylated, 3 (3%) were low-level/borderline, 7 (6%) were nonmethylated, and 7 (6%) were insufficient for testing. Sixteen cases (12 MLH1-hypermethylated, 3 nonmethylated, and 1 insufficient for testing) underwent germline testing, 6 of which (37.5%) demonstrated germline variants of unknown significance (VUS) (MSH6, PMS2, POLD1, BRIP1, RAD51D, CHEK2) but no known deleterious mutations. Notably, however, the patients harboring the MSH6 and PMS2 germline VUS had clinical features concerning for Lynch syndrome. One nonmethylated, germline-normal case underwent somatic tumor testing, and demonstrated a somatic MLH1 mutation. In summary, MLH1-hypermethylation accounts for the vast majority of MLH1/PMS2-deficient cancers in a universally screened population, although MLH1 somatic and germline mutations can occur. Occasionally, patients with MLH1-hypermethlated tumors also bear germline VUS in other mismatch repair genes as well as genes implicated in other hereditary cancer syndromes, but their clinical relevance is unclear. Family and personal cancer histories must always be evaluated to determine the need for germline testing in women with loss of MLH1/PMS2, even in the setting of hypermethylation.

Patient-reported outcome changes at the end of life in recurrent platinum-resistant ovarian cancer: An NRG oncology/GOG study.

OBJECTIVES: In a prospective study of platinum-resistant ovarian cancer patients, we examined whether the Disease-related Symptoms-Physical (DRS--P) scale of the NCCN/FACT-Ovarian Cancer Symptom Index-18 (NFOSI-18) is responsive to clinical change in patients estimated by their provider to survive at least six months. METHODS: The NFOSI-18, and other FACT measures, was collected at study entry and 3 and 6 months post-enrollment. Measures were compared for those who died or dropped off study prior to 3 months or prior to 6 months (assumed as health deterioration over time), or those who stayed on study through 6 months (presumed as stable disease over time). Statistical analyses included a fitted linear mixed model for estimating the group differences over time, Cox regression to assess the probability of survival with patient-reported outcomes, and effect size. RESULTS: DRS-P scores of patients who completed only one assessment were significantly lower compared to patients who were able to complete two assessments [5.9 points lower (2.0-9.8); p < 0.01], or three assessments [8.1 points lower (4.8-11.5); p < 0.01]. Measures of abdominal discomfort, functional well-being, emotional well-being, and quality of life were also significant, but treatment side effects were not. Further, in every scale except for neurotoxicity, higher (better) baseline scores were associated with a decreased likelihood of death, after adjusting for age, performance and disease status. CONCLUSION: The NFOSI-18 DRS-P scale is responsive to clinical change. It has potential as an indicator of changing health status with ovarian cancer disease progression, distinct from treatment side effects.

Characteristics of Immune Memory and Effector Activity to Cancer-Expressed MHC Class I Phosphopeptides Differ in Healthy Donors and Ovarian Cancer Patients.

Elevated immunity to cancer-expressed antigens can be detected in people with no history of cancer and may contribute to cancer prevention. We have previously reported that MHC-restricted phosphopeptides are cancer-expressed antigens and targets of immune recognition. However, the extent to which this immunity reflects prior or ongoing phosphopeptide exposures was not investigated. In this study, we found that preexisting immune memory to cancer-expressed phosphopeptides was evident in most healthy donors, but the breadth among donors was highly variable. Although three phosphopeptides were recognized by most donors, suggesting exposures to common microbial/infectious agents, most of the 205 tested phosphopeptides were not recognized by peripheral blood mononuclear cells (PBMC) from any donor and the remainder were recognized by only 1 to 3 donors. In longitudinal analyses of 2 donors, effector immune response profiles suggested active reexposures to a subset of phosphopeptides. These findings suggest that the immunogens generating most phosphopeptide-specific immune memory are rare infectious agents or incipient cancer cells with distinct phosphoproteome dysregulations, and that repetitive immunogenic exposures occur in individual donors. Phosphopeptide-specific immunity in PBMCs and tumor-infiltrating lymphocytes from ovarian cancer patients was limited, regardless of whether the phosphopeptide was expressed on the tumor. However, 4 of 10 patients responded to 1 to 2 immunodominant phosphopeptides, and 1 showed an elevated effector response to a tumor-expressed phosphopeptide. As the tumors from these patients displayed many phosphopeptides, these data are consistent with lack of prior exposure or impaired ability to respond to some phosphopeptides and suggest that enhancing phosphopeptide-specific T-cell responses could be a useful approach to improve tumor immunotherapy.

"Moving Away From Cancer" Prospective Exercise Trial for Female Rural Cancer Survivors: How Can We Step It Up?

PURPOSE: This prospective trial's objective was to determine feasibility and outcomes of an exercise-based intervention for rural overweight/obese female cancer survivors. MATERIALS AND METHODS: Survivors of endometrial, breast, or ovarian cancer enrolled in a 6-month program of increased aerobic activity (30 minutes daily walking) and strength-training exercises using exercise bands (THERABAND; Akron, OH) with personalized telephone motivational coaching. Baseline demographics, anthropomorphic measurements, quality of life (QOL), fitness, and readiness to adopt exercise changes were assessed; daily steps, band use, and follow-up measurements were assessed at 3 and 6 months. Study completion was modeled using logistic regression. RESULTS: The mean age of the 99 women was 59.9 years, the mean body mass index (BMI) was 35.9 kg/m2, 88.9% were white, and 41.4% reported current exercise. Fifty-five women (55.6%) completed the 6-month program, and 36 (36.4%) completed exercise interventions. Using logistic regression to model study completion, only baseline QOL scores (physical component summary) and mental component summary) remained significant predictors. The mean weight change was a gain (0.88 kg). Higher MCS baseline scores and prior regular exercise predicted continued exercise and increased step counts, whereas higher BMI and baseline sleep predicted decreased QOL. Top walking barriers were feeling unwell and weather; barriers to strength exercises were band dislike and pain. CONCLUSION: The most significant predictor of trial completion and improved exercise outcomes was a higher baseline mental QOL. Motivation, belief in the importance of exercise, and prescribed/monitored exercise regimens were not sufficient; supportive and cognitive behavioral therapy interventions for survivors are needed to sustain uptake.

Development and Impact of an Institutional Enhanced Recovery Program on Opioid Use, Length of Stay, and Hospital Costs Within an Academic Medical Center: A Cohort Analysis of 7774 Patients.

BACKGROUND: Enhanced Recovery (ER) is a change management framework in which a multidisciplinary team of stakeholders utilizes evidence-based medicine to protocolize all aspects of a surgical care to allow more rapid return of function. While service-specific reports of ER adoption are common, institutional-wide adoption is complex, and reports of institution-wide ER adoption are lacking in the United States. We hypothesized that ER principles were generalizable across an institution and could be implemented across a multitude of surgical disciplines with improvements in length of stay, opioid consumption, and cost of care. METHODS: Following the establishment of a formal institutional ER program, ER was adopted in 9 distinct surgical subspecialties over 5 years at an academic medical center. We compared length of stay, opioid consumption, and total cost of care in all surgical subspecialties as a function of time using a segmented regression/interrupted time series statistical model. RESULTS: There were 7774 patients among 9 distinct surgical populations including 2155 patients in the pre-ER cohort and 5619 patients in the post-ER cohort. The introduction of an ER protocol was associated with several significant changes: a reduction in length of stay in 5 of 9 specialties; reduction in opioid consumption in 8 specialties; no change or reduction in maximum patient-reported pain scores; and reduction or no change in hospital costs in all specialties. The ER program was associated with an aggregate increase in profit over the study period. CONCLUSIONS: Institution-wide efforts to adopt ER can generate significant improvements in patient care, opioid consumption, hospital capacity, and profitability within a large academic medical center.

Phase II study of atezolizumab in combination with bevacizumab in patients with advanced cervical cancer.

BACKGROUND: There are limited treatment options for patients with metastatic or recurrent cervical cancer. Platinum-based chemotherapy plus the anti-vascular endothelial growth factor antibody bevacizumab remains the mainstay of advanced treatment. Pembrolizumab is Food and Drug Agency approved for programmed death ligand 1 (PD-L1) positive cervical cancer with a modest response rate. This is the first study to report the efficacy and safety of the PD-L1 antibody atezolizumab in combination with bevacizumab in advanced cervical cancer. METHODS: We report the results from a phase II, open-label, multicenter study (NCT02921269). Patients with advanced cervical cancer were treated with bevacizumab 15 mg/kg intravenous every 3 weeks and atezolizumab 1200 mg intravenous every 3 weeks. The primary objective was to measure the objective response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS: In the total evaluable population (n=10), zero patients achieved an objective response as assessed by Response Evaluation Criteria In Solid Tumors (RECIST) V.1.1, resulting in a confirmed ORR of 0%. Of note, there were two patients who achieved an unconfirmed PR. The DCR by RECIST V.1.1 was 60% (0% complete response, 0% partial response, 60% stable disease). Median PFS was 2.9 months (95% CI, 1.8 to 6) and median OS was 8.9 months (95% CI, 3.4 to 21.9). Safety results were generally consistent with the known safety profile of both drugs, notably with two high-grade neurologic events. CONCLUSIONS: The combination of bevacizumab and atezolizumab did not meet the predefined efficacy endpoint, as addition of bevacizumab to PD-L1 blockade did not appear to enhance the ORR in cervical cancer.
