Cost-effectiveness analysis of atezolizumab plus bevacizumab and chemotherapy for the treatment of metastatic, persistent, or recurrent cervical cancer (BEATcc)

ABSTRACT Background The addition of atezolizumab to bevacizumab plus platinum regimen has demonstrated notable improvements in treating metastatic, persistent, or recurrent cervical cancer, but its cost-effectiveness requires further investigation. From a US payer perspective, we aimed to evaluate the cost-effectiveness of atezolizumab plus bevacizumab and chemotherapy vs. standard chemotherapy as a first-line treatment for metastatic, persistent, or recurrent cervical cancer. Methods A partitioned survival model based on the data from the BEATcc trial was used to calculate the incremental cost-effectiveness ratio (ICER), using cost and health utility information obtained from literature and publicly accessible databases. One-way and probabilistic sensitivity analyses were performed to evaluate the model’s responsiveness to variations in parameters. Results The addition of atezolizumab resulted in an additional 0.839 quality-adjusted life years (QALY) at an additional cost of $458,237, leading to an ICER of $545,943/QALY. One-way sensitivity analysis indicated that the cost of atezolizumab had the greatest impact on the ICER, followed by the utility value of progression-free survival (PFS) and follow-up costs. Probabilistic sensitivity analysis showed a 0% cost-effectiveness probability at the current willingness-to-pay (WTP) threshold of $150,000 per QALY. Conclusion Adding atezolizumab to chemotherapy is cost-prohibitive in the US and may not be cost-effective for patients.

Atezolizumab plus bevacizumab and chemotherapy versus bevacizumab plus chemotherapy for metastatic cervical cancer: a cost-effectiveness analysis

AimThe objective of this study is to conduct a cost-effectiveness analysis in order to evaluate the economic advantages of incorporating atezolizumab into a standard bevacizumab plus platinum regimen for the treatment of metastatic cervical cancer from the Chinese medical system perspective.MethodWe developed a partitioned survival model based on data obtained from the recently published BEATcc clinical trial and economic cost data. Our model utilized a tree-based decision analysis approach to simulate two different treatment strategies for metastatic cervical cancer: the standard bevacizumab plus platinum regimen, and the addition of atezolizumab to the standard treatment regimen. The economic assessment data included the costs of the drugs, costs related to treatment-induced adverse events. The cost-effectiveness metrics used in the analysis were quality-adjusted life-year (QALY) and incremental cost-effectiveness ratio (ICER). The robustness of our model was assessed through sensitivity analysis.ResultThe total costs of the atezolizumab group were $128179.56, while the costs of chemotherapy group were $42065.89. The atezolizumab group gained 3.52 QALYs, whereas the chemotherapy group gained 2.35 QALY. The atezolizumab regimen resulted in an increase of 1.17 QALYs at an incremental cost of $86113.67. This led to an ICER of $73601.43, which exceeds the willingness-to-pay (WTP) threshold of $39855.79 in China. Sensitivity analysis demonstrated none of the parameters within a margin of ±25% result in significant alterations to the analysis findings.ConclusionAtezolizumab plus bevacizumab and chemotherapy was not to be a cost-effective option for the treatment of metastatic cervical cancer compared to bevacizumab plus chemotherapy.

Safety and efficacy of tisotumab vedotin with cervical cancers: A systematic review and meta-analysis.

Tisotumab vedotin (TV) holds promise for treating recurrence or metastatic cervical cancer (r/mCC), with recent FDA approval for second-line use in recurrent or metastatic cases. Our research aims to evaluate TV's efficacy and safety in these patients, focusing on overall survival (OS) and progression-free survival (PFS) outcomes. We searched five electronic databases in February 2024, retrieved articles, screened them based on inclusion and exclusion criteria, and assessed their quality. A meta-analysis of the extracted data was performed and applied a random-effects model for our analysis. The search identified 86 articles, with six meeting the inclusion criteria. Meta-analysis revealed 80.8% and 48.0% OS at 6 and 12 months, and a 29.9% PFS at 6 months. Combined treatment with carboplatin or pembrolizumab showed 33.0% PFS at 1 year and 15.1% at 2 years. The objective response rate (ORR) was 21.0%, reaching 43.3% with combined treatment. Confirmed disease control rate (CDCR) was 70.0% overall and in combination. The median duration of response (DOR) was 6.1 months, increasing to 9.5 months in combined treatment, with a consistent time to response (TTR) of 1.4 months. Adverse events included ocular issues (conjunctivitis 30.3%, dry eye 18.7%) and common side effects (nausea 38.4%, epistaxis 35.7%). This systematic review and meta-analysis highlights the potential of TV as a treatment option for r/mCC patients. However, healthcare providers must communicate safety profiles and recommend prophylactic measures for optimal patient outcomes. Further studies, particularly assessing combination treatments, are needed to clarify TV's role in treatment algorithms and improve clinical outcomes.

Plasma-based proteomic and metabolomic characterization of lung and lymph node metastases in cervical cancer patients

Metastasis is the leading cause of mortality in cervical cancer (CC), with a particular prevalence of lymph node and lung metastases. Patients with CC who have developed distant metastases typically face a poor prognosis, and there is a scarcity of non-invasive strategies for predicting CC metastasis. In this study, we utilized label-free proteomics and untargeted metabolomics to analyze plasma samples from 25 non-metastatic, 14 with lung metastasis, and 15 with lymph node metastasis CC patients. Pathway enrichment analysis revealed a shared inflammatory process between the two metastatic groups, while the central carbon metabolism in cancer showed distinct features in the lung metastasis cohort. Additionally, cholesterol metabolism, hypoxia-inducible factor 1, and ferroptosis signaling pathways were specifically altered in the lymph node metastasis group. Utilizing the receiver operating characteristic curve analysis and Random Forest algorithm, we identified two distinct biomarker panels for the prediction of lung metastasis and lymph node metastasis, respectively. The lung metastasis panel includes properdin, neural cell adhesion molecule 1, and keratin 6 A, whereas the lymph node metastasis panel consists of quiescin sulfhydryl oxidase 1, paraoxonase 1, and keratin 6 A. Each panel exhibited significant diagnostic potential, with high area under the curve (AUC) values for lung metastasis (training set: 0.989, testing set: 0.789) and lymph node metastasis (training set: 0.973, testing set: 0.900). This study conducted an integrated proteomic and metabolomic analysis to clarify the factors contributing to lung and lymph node metastases in CC and has successfully established two biomarker panels for their prediction.

The importance of MRI in determining the stage of cervical cancer

Cervical cancer is one of the most common malignant tumours in women. The treatment of early and locally advanced stages of this cancer typically involves surgery, chemotherapy, and radiotherapy. However, there is no standardised therapy for metastatic cervical cancer due to the diverse manifestations of the disease. Therefore, timely diagnosis and staging of the carcinoma are crucial for maintaining the quality of life of patients. Imaging during the initial diagnostic evaluation is essential for accurately assessing the extent of the tumour and metastases, and for selecting the optimal therapy, with the FIGO system further emphasising this role. Compared to other imaging techniques, MRI provides detailed information on the location and size of the tumour, invasion into surrounding tissues, and the presence of distant metastases. This allows MRI to facilitate a tailored approach in therapy selection, taking into account the specific characteristics of the tumour. The integration of MRI into the diagnostic and therapeutic process improves clinical outcomes for patients with cervical cancer, enabling effective care. MRI is used alongside other imaging modalities in the diagnosis and treatment planning, and without it, precise staging of the disease and establishing a final diagnosis would not be possible.

Clinical and ultrasound features of uterine perivascular epithelioid cell tumors: case series and literature review.

To describe the clinical and ultrasonographic features of uterine perivascular epithelioid cell tumor (PEComa) using standardized terminology. This was a retrospective analysis of patients with uterine PEComa diagnosed and confirmed by pathology and immunohistochemistry at West China Second University Hospital, Sichuan University, Sichuan, China, between January 2010 and September 2023. The Morphological Uterus Sonographic Assessment (MUSA) consensus and the International Endometrial Tumor Analysis (IETA) consensus were utilized for the standardized description of the sonographic characteristics of uterine PEComa. We summarized the clinical and ultrasound features of uterine PEComa in cases from our center and those found in a review of the literature conducted using PubMed from 1 January 2013 to 30 September 2023 (inclusive). Five patients, aged 33-57 (median, 52) years with a total of six uterine PEComa lesions were included in our cohort. All cases had complete ultrasonographic and pathological images. None of the patients had a history of tuberous sclerosis complex. Two patients had malignant PEComa (one patient had two lesions) and three had benign PEComa, originating from the cervix, myometrium or uterine cavity. Patients presented with symptoms including increased vaginal discharge, vaginal bleeding and pelvic or abdominal pain. The three patients with benign PEComa underwent total hysterectomy and bilateral adnexectomy, tumor excision and conservative management, respectively, while both malignant cases underwent total hysterectomy and bilateral adnexectomy followed by chemotherapy. Regular follow-up (from 6 to 24 months) revealed recurrence in one case. Two lesions were misdiagnosed as uterine fibroids, two as cervical cancer, one as metastatic cervical cancer (with myometrial invasion) and one was indeterminate. Ultrasound examination showed that most lesions displayed regular round or ovoid shapes (66.7%), uniform echoes (66.7%) and hypoechogenicity (66.7%), with one (16.7%) malignant PEComa showing cystic areas and one (16.7%) benign PEComa showing punctate calcifications. All lesions lacked shadowing and the majority showed moderate to abundant vascularity (color score of 3-4, 83.3%). The color score was 2-4 in the periphery in 100% of cases and internally in 83.3% of cases. The three benign PEComas showed similar characteristics in vascular distribution, with scattered internal vessels and peripheral vessels exhibiting a circular pattern. The literature search identified 11 articles describing the ultrasonographic appearance of 18 cases of uterine PEComa, with similar characteristics to those in our cohort. The sonographic features of uterine PEComa include a uniform or non-uniform hypoechogenic mass, typically round or ovoid with regular margins, occasionally containing cystic areas or calcifications, lacking shadowing and often showing moderate to abundant vascularity. Although the preoperative ultrasound diagnosis of uterine PEComa remains challenging, particularly given the non-specific nature of the sonographic characteristics described here, dispersed intratumoral vessels and a peripheral circular vascular distribution may serve as diagnostic clues for uterine PEComa, but more cases are needed for confirmation. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Cadonilimab plus platinum-based chemotherapy with or without bevacizumab as first-line treatment for persistent, recurrent, or metastatic cervical cancer (COMPASSION-16): a randomised, double-blind, placebo-controlled phase 3 trial in China

Cadonilimab is a bispecific antibody targeting PD-1 and CTLA-4, which has shown substantial clinical benefits in advanced cervical cancer. In the COMPASSION-16 trial, we aimed to evaluate the addition of cadonilimab to first-line standard chemotherapy in persistent, recurrent, or metastatic cervical cancer. In this randomised, double-blind, multicentre, placebo-controlled phase 3 trial, women aged 18-75 years across 59 clinical sites in China with previously untreated persistent, recurrent, or metastatic cervical cancer were randomly assigned (1:1) to receive cadonilimab (10 mg/kg) or placebo plus platinum-based chemotherapy with or without bevacizumab every 3 weeks for six cycles, followed by maintenance therapy every 3 weeks for up to 2 years. Randomisation was performed centrally through an interactive web-response system. Stratification factors were the use of bevacizumab (yes or no) and previous concurrent chemoradiotherapy (yes or no). The dual primary outcomes were progression-free survival as assessed by blinded independent central review and overall survival in the full analysis set. This study is registered with ClinicalTrials.gov, NCT04982237; the study has completed enrolment and is ongoing for treatment and follow-up. 445 eligible women were enrolled between Sept 11, 2021, and June 23, 2022. Median progression-free survival was 12·7 months (95% CI 11·6-16·1) in the cadonilimab group and 8·1 months (7·7-9·6) in the placebo group (hazard ratio 0·62 [95% CI 0·49-0·80], p<0·0001); median overall survival was not reached (27·0 months to not estimable) versus 22·8 months (17·6-29·0), respectively (hazard ratio 0·64 [0·48-0·86], p=0·0011). The most common grade 3 or higher adverse events were decreased neutrophil count, decreased white blood cell count, and anaemia. The addition of cadonilimab to first-line standard chemotherapy significantly improved progression-free survival and overall survival with a manageable safety profile in participants with persistent, recurrent, or metastatic cervical cancer. The data support the use of cadonilimab plus chemotherapy as an efficacious first-line therapy in persistent, recurrent, or metastatic cervical cancer. Akeso Biopharma.

Improved outcomes of palliative radiotherapy combined with immune checkpoint inhibitors in recurrent or metastatic cervical cancers

BackgroundImmunotherapy provides a remarkable survival advantage for patients with recurrent or metastatic cervical cancer (R/M CC). However, the role of immunotherapy in combination with radiotherapy in R/M CC remains unclear. MethodsWe retrospectively analyzed factors affecting immunotherapy effectiveness in patients with R/M CC. Clinical outcomes including tumor response and patient survival were assessed. Kaplan-Meier curves with the log-rank test were employed to compare survival data. Cox regression analysis was utilized to investigate prognostic factors. ResultsA total of 65 R/M CC patients treated with immune checkpoint inhibitors were eligible for analysis. We found that immunotherapy combined with palliative radiotherapy showed a significant positive correlation with complete response (OR = 6.31; 95 %CI: 1.74–22.91; p = 0.005). The 36-month progression-free survival (PFS) rate (73.7 % vs 33.8 %, p = 0.0048) and 36-month overall survival (OS) rate (85.7 % vs 38.7 %, p = 0.0043) were also prominently increased. We further demonstrated that patients prolonged 36-month PFS rate (69.9 % vs 15.2 %; p < 0.001) and 36-month OS rate (64.6 % vs 39.7 %; p = 0.032) when they had more than 4 cycles of immunotherapy. Meanwhile, our findings showed that patients with only recurrence had longer 36-month OS rate (77.7 % vs 44.4 % vs 40.1 %; p = 0.024) compared to those with only metastasis and both. We also observed that patients with squamous carcinoma had higher 2-year PFS rate (57.9 % vs 14.6 %; p = 0.042) than those with other pathological subtypes (adenocarcinoma, adenosquamous carcinoma and neuroendocrine carcinoma). ConclusionsThe combination of immunotherapy and palliative radiotherapy increased complete response rates and improved survivals in recurrent or metastatic cervical cancer patients.

Pembrolizumab plus chemotherapy for advanced and recurrent cervical cancer: final analysis according to bevacizumab use in the randomized KEYNOTE-826 study

In KEYNOTE-826 (NCT03635567), pembrolizumab plus chemotherapy (± bevacizumab) significantly improved overall survival (OS) and progression-free survival (PFS) in patients with persistent, recurrent, or metastatic cervical cancer. This exploratory analysis examined outcomes in patient subgroups defined by bevacizumab use. Eligible adult patients had persistent, recurrent, or metastatic squamous cell carcinoma, adenosquamous carcinoma, or adenocarcinoma of the cervix not previously treated with chemotherapy and not amenable to curative treatment; measurable disease per RECIST v1.1; and an Eastern Cooperative Oncology Group performance status ≤1. Patients were randomized 1:1 to pembrolizumab 200 mg every 3 weeks or placebo for up to 35 cycles plus chemotherapy (± bevacizumab 15 mg/kg). Dual primary endpoints were OS and PFS per RECIST v1.1 by investigator assessment. Outcomes were assessed in subgroups defined by bevacizumab use. Hazard ratios (HRs) and 95% CIs were based on a stratified Cox regression model. 617 patients were randomized (pembrolizumab arm, n=308 [63.6% with bevacizumab]; placebo arm, n=309 [62.5% with bevacizumab]). The most common reason for bevacizumab exclusion was medical contraindication (75.9%). Among patients who received bevacizumab, HRs (95% CIs) for PFS favored the pembrolizumab arm in the PD-L1 combined positive score (CPS) ≥1 (0.56 [0.43-0.73]) and all-comer (0.57 [0.45-0.73]) populations; OS results were 0.60 (0.45-0.79) and 0.61 (0.47-0.80), respectively. Among patients who did not receive bevacizumab, HRs (95% CIs) for PFS also favored the pembrolizumab arm in the PD-L1 CPS≥1 (0.61 [0.44-0.85]) and all-comer (0.69 [0.50-0.94]) populations; OS results were 0.61 (0.44-0.85) and 0.67 (0.49-0.91), respectively. Among patients who received bevacizumab, grade ≥3 treatment-related adverse events occurred in 74.0% of patients in the pembrolizumab arm and 66.8% in the placebo arm. Pembrolizumab plus chemotherapy prolonged PFS and OS and had manageable safety compared with placebo plus chemotherapy in patient subgroups defined by bevacizumab use.

The efficacy of first and second immunotherapy exposure in patients with recurrent or metastatic cervical cancer.

Immunotherapy has led to changes in cervical cancer guidelines. Therefore, additional biomarkers to identify the ideal patient who would experience the most benefit may be important. We retrospectively collected 208 patients with R/M CC and recorded clinicopathologic information, peripheral blood markers and treatments to analyze the prognostic factors of clinical outcomes. Response rate comparison, univariate, and multivariate analyses were performed to assess the efficacy of different factors. A total of 43.27% patients achieved objective responses, including 18 with complete response and 72 with partial response. Patients receiving first-line immunotherapy had much higher objective response rate (ORR) than the remaining patients (53.8% vs. 34.8%, p = 0.006). CRP >3 ECOG ≥1 and recurrence in 6 months predicted shorter progression free survival (PFS). CRP >3, GLU >6.1 independently predicted unfavorable overall survival (OS). Compared with no antiangiogenic therapy, previous antiangiogenic therapy reduced the median OS by nearly 14 months. Immunotherapy rechallenge was still effective after first immunotherapy failure, and combined with dual-immunotherapy or bevacizumab combined with chemoradiotherapy resulted in a 60.00% or 62.50% ORR, respectively. Patients with squamous cell carcinoma, with stable disease or objective response in the first immunotherapy or without chemotherapy in second immunotherapy had favorable clinical outcome. The baseline CRP levels in serum was an independent factor for PFS and OS of R/M CC patients treated with immunotherapy, and previous antiangiogenic therapy was associated with poor OS. Patients still show response to immunotherapy rechallenge and combined treatment with bevacizumab or candonilimab showed higher response rate than anti-PD-1 after immunotherapy failure.
