Abstract
BACKGROUND Standard of care for adjuvant treatment of stage III endometrial cancer includes chemotherapy and radiation. In addition to stage, tumor molecular profiles may predict treatment outcomes, and prospective clinical trials are ongoing. However, tumor molecular testing is costly and time-consuming. Our objective was to evaluate the cost-effectiveness of tumor molecular testing in stage III endometrial cancer. METHODS A Markov decision model compared two strategies for stage III endometrial cancer: Tumor Molecular Testing (TMT) versus No TMT. TMT included sequential POLE next generation sequencing, mismatch repair immunohistochemistry (IHC), and p53 IHC. POLE-mutated patients were assigned to adjuvant radiation therapy; all others including controls were assigned to adjuvant chemoradiation. First recurrences were treated with 6 cycles of carboplatin and paclitaxel. Second recurrences were treated with pembrolizumab alone for mismatch repair deficient patients and both pembrolizumab and lenvatinib for other patients. Sensitivity analyses were performed to test model robustness. RESULTS Compared to No TMT, TMT was cost saving with equivalent effectiveness. On one-way sensitivity analysis, TMT remained cost saving over all parameter ranges. TMT was also favored on probabilistic sensitivity analysis in 80% of iterations at a willingness-to-pay threshold of $100,000/quality adjusted life-year (QALY) gained. However, when TMT was compared to mismatch repair IHC alone, TMT cost $182,798/QALY gained. CONCLUSIONS In this model of patients with stage III endometrial cancer, TMT was cost saving compared to No TMT. However, when compared to mismatch repair IHC alone, TMT was economically unfavorable.

WOMEN'S HEALTH REPORTS 2022; 3:369-384. [PMID: 35415718 PMCID: PMC8994439 DOI: 10.1089/whr.2021.0101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 02/22/2022] [Indexed: 11/09/2022]
Abstract
Background: Following a 2014 safety warning (that laparoscopic power morcellation may increase tumor dissemination if patients have occult uterine cancer), hysterectomy practice shifted from laparoscopic to abdominal approach. This avoided morcellating occult cancer, but increased perioperative complications. To inform the national impact of this practice change, we examined the cost-effectiveness of hysterectomy practice in the postwarning period, in comparison to counterfactual hysterectomy practice had there been no morcellation warning. Materials and Methods: We constructed a decision tree model to simulate relevant outcomes over the lifetime of patients in the national population undergoing hysterectomy for presumed benign indications. The model accounted for both hysterectomy- and occult cancer-related outcomes. Probability-, cost-, and utility weight-related input parameters were derived from analysis of the State Inpatient Databases, State Ambulatory Surgery and Services Databases, data from the New York Statewide Planning and Research Cooperative System and New York State Cancer Registry, and published literature. Results: With an estimated national sample of 353,567 adult women, base case analysis showed that changes in hysterectomy practice after the morcellation warning led to a net gain of 867.15 quality-adjusted life years (QALYs), but an increase of $19.54 million in costs (incremental cost-effectiveness ratio = $22,537/QALY). In probabilistic sensitivity analysis, the practice changes were cost-effective in 54.0% of the simulations when evaluated at a threshold of $50,000/QALY, which increased to 70.9% when evaluated at a threshold of $200,000/QALY. Conclusion: Hysterectomy practice changes induced by the morcellation warning are expected to be cost-effective, but uncertainty in parameter values may affect the cost-effectiveness results.

Cost-effectiveness analysis of tumor molecular classification in high-risk early-stage endometrial cancer. Gynecol Oncol 2021; 164:129-135.

Abstract
PURPOSE Tumor molecular analyses in endometrial cancer (EC) includes 4 distinct subtypes: (1) POLE-mutated, (2) mismatch repair protein (MMR) deficient, (3) p53 mutant, and (4) no specific molecular profile. Recently, a sub-analysis of PORTEC-3 demonstrated notable differences in treatment response between molecular classification (MC) groups. Cost of testing is one barrier to widespread adoption of MC. Therefore, we sought to determine the cost-effectiveness of MC in patients with stage I and II high-risk EC. METHODS A Markov decision model was developed to compare tumor molecular classification (TMC) vs. no testing (NT). A healthcare payor's perspective and 5-year time horizon were used. Base case data were abstracted from PORTEC-3 and the molecular sub-analysis. Cost and utility data were derived from public databases, peer-reviewed literature, and expert input. Strategies were compared using the incremental cost-effectiveness ratio (ICER) with effectiveness in quality-adjusted life years (QALYs) and evaluated with a willingness-to-pay threshold of $100,000 per QALY gained. Sensitivity analyses were performed to test model robustness. RESULTS When compared to NT, TMC was cost effective with an ICER of $25,578 per QALY gained; incremental cost was $1780 and incremental effectiveness was 0.070 QALYs. In one-way sensitivity analyses, results were most sensitive to the cost of POLE testing, but TMC remained cost-effective over all parameter ranges. CONCLUSIONS TMC in early-stage high-risk EC is cost-effective, and the model results were robust over a range of parameters. Given that MC can be used to guide adjuvant treatment decisions, these findings support adoption of TMC into routine practice.

Diabetes Metab Syndr Obes 2021; 14:3147-3160. [PMID: 34267531 PMCID: PMC8275158 DOI: 10.2147/dmso.s284855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Accepted: 06/04/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Obesity is a disease associated with high direct medical costs and high indirect costs resulting from productivity loss. The high prevalence of obesity generates the need for payers to identify cost-effective weight loss approaches. Among various weight management techniques, the OPTI (Optifast®) program is a clinically recognised total meal replacement diet that can lead to significant weight loss and reduction in complications. This study's objective is to assess OPTI program's cost-effectiveness in Switzerland in comparison to "no intervention" and pharmacotherapy. METHODS An event-driven decision-analytic model was used to estimate the payer's cost savings through the reimbursement of OPTI program over a 1-year period as well as a lifetime in Switzerland. The analysis was performed on a broad population of people with obesity with a body mass index (BMI) higher than 30 kg/m2 following the OPTI program vs two comparators (liraglutide and "no intervention"). The model incorporated a higher risk of complications due to an increased BMI and their related healthcare costs. Data sources included published literature, clinical trials, official Swiss price/tariff lists and national population statistics. The primary perspective was that of a Swiss payer. Scenario analyses - for example, for patients with existing complications (such as myocardial infarction, stroke, type 2 diabetes mellitus) or severe obesity - were conducted to test the robustness of the results. RESULTS The OPTI program results in cost savings of CHF 20,886 (€ 18,724) and CHF 15,382 (€ 13,790) per person compared with "no intervention" and liraglutide 3 mg, respectively. In addition, OPTI program led to 1.133 and 0.734 quality-adjusted life years (QALYs) gained respectively against its comparators. Scenario analyses showed similar outcomes with cost savings and QALYs gained. CONCLUSION OPTI program is a dominant strategy compared to "no intervention" and liraglutide 3 mg as it leads to both cost savings and QALY gain. Therefore, reimbursing the OPTI program for patients with obesity would be cost-effective for Swiss payers.

Abstract
BACKGROUND Radiological preoperative assessment of endometrial cancer (EC) is in some cases not precise enough and its performances improvement could lead to a clinical benefit. Radiomics is a recent field of application of artificial intelligence (AI) in radiology. AIMS To investigate the contribution of radiomics on the radiological preoperative assessment of patients with EC; and to establish a simple and reproducible AI Quality Score applicable to Machine Learning and Deep Learning studies. METHODS We conducted a systematic review of current literature including original articles that studied EC through imaging-based AI techniques. Then, we developed a novel Simplified and Reproducible AI Quality score (SRQS) based on 10 items which ranged to 0 to 20 points in total which focused on clinical relevance, data collection, model design and statistical analysis. SRQS cut-off was defined at 10/20. RESULTS We included 17 articles which studied different radiological parameters such as deep myometrial invasion, lympho-vascular space invasion, lymph nodes involvement, etc. One article was prospective, and the others were retrospective. The predominant technique was magnetic resonance imaging. Two studies developed Deep Learning models, while the others machine learning ones. We evaluated each article with SRQS by 2 independent readers. Finally, we kept only 7 high-quality articles with clinical impact. SRQS was highly reproducible (Kappa = 0.95 IC 95% [0.907-0.988]). CONCLUSION There is currently insufficient evidence on the benefit of radiomics in EC. Nevertheless, this field is promising for future clinical practice. Quality should be a priority when developing these new technologies.

Abstract
PURPOSE Clinicopathologic data from a population-based endometrial cancer cohort, unselected for age or family history, were analyzed to determine the optimal scheme for identification of patients with germline mismatch repair (MMR) gene mutations. PATIENTS AND METHODS Endometrial cancers from 702 patients recruited into the Australian National Endometrial Cancer Study (ANECS) were tested for MMR protein expression using immunohistochemistry (IHC) and for MLH1 gene promoter methylation in MLH1-deficient cases. MMR mutation testing was performed on germline DNA of patients with MMR-protein deficient tumors. Prediction of germline mutation status was compared for combinations of tumor characteristics, age at diagnosis, and various clinical criteria (Amsterdam, Bethesda, Society of Gynecologic Oncology, ANECS). RESULTS Tumor MMR-protein deficiency was detected in 170 (24%) of 702 cases. Germline testing of 158 MMR-deficient cases identified 22 truncating mutations (3% of all cases) and four unclassified variants. Tumor MLH1 methylation was detected in 99 (89%) of 111 cases demonstrating MLH1/PMS2 IHC loss; all were germline MLH1 mutation negative. A combination of MMR IHC plus MLH1 methylation testing in women younger than 60 years of age at diagnosis provided the highest positive predictive value for the identification of mutation carriers at 46% versus ≤ 41% for any other criteria considered. CONCLUSION Population-level identification of patients with MMR mutation-positive endometrial cancer is optimized by stepwise testing for tumor MMR IHC loss in patients younger than 60 years, tumor MLH1 methylation in individuals with MLH1 IHC loss, and germline mutations in patients exhibiting loss of MSH6, MSH2, or PMS2 or loss of MLH1/PMS2 with absence of MLH1 methylation.

Abstract
A shift toward a disease-based therapy designed according to patterns of failure and likelihood of nodal involvement predicted by pathologic determinants has recently led to considering a selective approach to lymphadenectomy for endometrial cancer. Therefore, it became critical to examine reproducibility of diagnosing the key determinants of risk, on preoperative endometrial tissue samples as well as the concordance between preoperative and postresection specimens. Six gynaecologic pathologists assessed 105 consecutive endometrial biopsies originally reported as positive for endometrial cancer for cell type (endometrioid versus nonendometrioid), tumor grade (FIGO 3-tiered and 2-tiered), nuclear grade, and risk category (low risk defined as endometrioid histology, grade 1 + 2 and nuclear grade <3). Interrater agreement levels were substantial for identification of nonendometrioid histology (κ = 0.63; SE = 0.025), high tumor grade (κ = 0.64; SE = 0.025), and risk category (κ = 0.66; SE = 0.025). The overall agreement was fair for nuclear grade (κ = 0.21; SE = 0.025). There is agreement amongst pathologists in identifying high-risk pathologic determinants on endometrial cancer biopsies, and these highly correlate with postresection specimens. This is ascertainment prerequisite adaptation of the paradigm shift in surgical staging of patients with endometrial cancer.

Abstract
OBJECTIVE To compare the practices, adjuvant treatment, and outcomes of patients with preoperatively assessed grade 1 endometrioid endometrial cancer between two academic gynecologic oncology centers that use different treatment strategies. METHODS A retrospective analysis was performed at Duke University Medical Center (Duke) and the Toronto Sunnybrook Regional Cancer Center (Sunnybrook) between 1991 and 2007. Patients at Duke generally underwent surgical staging unless intraoperative assessment identified a negligible risk of nodal disease. Patients at Sunnybrook generally did not undergo surgical staging. RESULTS A total of 494 patients (272 from Duke and 222 from Sunnybrook were identified with preoperative, central-review-confirming, grade 1, endometrioid, endometrial cancer. Groups were similar in grade, final histology, type of hysterectomy, and length of hospital stay. Patients from Sunnybrook were older (aged 62 years compared with 59 years, P=.001) and were more likely to have capillary lymphatic space involvement (18.2% compared with 8.3%, P=.003) and cervical involvement (12.2% compared with 3.7%, P<.001). Approximately 2% of cases were upgraded to high grade on final specimen. Lymphadenectomy was performed on 49.4% of patients at Duke compared with 11.7% of patients at Sunnybrook. Overall 3-year survival was 96% at Duke and 96% at Sunnybrook (P=.217). Three-year recurrence-free survival was 96% at Duke and 95% at Sunnybrook (P=.327). CONCLUSION Despite differences in practice and slight differences in patient populations, the recurrence-free and overall survival of women with preoperative centrally reviewed grade 1 endometrial cancer is excellent and without statistically significant difference between the two centers.

Abstract
OBJECTIVE To conduct a population-based study of incidence and screening rates for secondary breast and colorectal cancers after endometrial cancer and to assess implications for follow-up. METHODS This was a retrospective population-based study from administrative databases. The inception cohort included all women diagnosed with endometrial cancer in Ontario, Canada from 1996 to 2000, without a previous history of breast or colorectal cancer. We ascertained 5-year recurrence and overall survival rates and practitioner type during follow-up. Primary outcomes were age-standardized incidence and screening rates of breast and colorectal cancer during follow-up compared with the general female population. RESULTS There were 3,473 women in the cohort. The 5-year recurrence rate was 15.0% and overall survival was 79.3%. Family physicians were most often involved in follow-up care. Age-standardized incidence rates of breast and colorectal cancer were 0.5% and 0.7%, respectively, compared with 0.5% (P=.76) and 0.2% (P<.001) in the general population. Age-standardized screening rates for these cancers were 64.0% and 30.0%, respectively, compared with 31.0% (P<.008) and 15.0% (P<.001) in the general population. Women aged older than 70 years and those with the lowest income were least likely to have secondary cancer screening. CONCLUSION Women with endometrial cancer have a comparable risk of breast cancer but higher risk of colorectal cancer compared with the general population. Follow-up after endometrial cancer should include counseling and uptake of secondary cancer prevention strategies, which will contribute to maximizing long-term survivorship for these women.

Abstract
Endometrial cancer is the most common gynecologic malignancy in the United States. The majority of women are diagnosed with early-stage disease. Surgical therapy of early-stage endometrial cancer includes full staging, including pelvic and para-aortic lymphadenectomy. While most women with early-stage endometrial cancer can anticipate cure with surgery alone, a significant minority of women with deeply invasive or high-grade tumors will experience local, regional, or distant recurrences of their disease. Therefore, adjuvant therapies have been proposed for these women. While radiotherapy is effective at reducing the risk of local and regional tumor recurrence, studies have demonstrated no improvement on survival. The role of systemic adjuvant chemotherapies in this high-risk, early-stage patient population is currently the focus of several randomized trials. In addition, for women with early-stage tumors with atypical histology, such as papillary serous and clear cell malignancies, the role of adjuvant therapy remains uncertain. Optimizing management of women with early-stage disease requires a careful assessment of the risk of recurrent disease, the potential benefit of various adjuvant strategies, and the risk associated with adjuvant therapy. New molecular markers may be helpful in the future to refine our ability to identify high-risk, early-stage patients.
