A Cost-Effectiveness and Quality of Life Analysis of Different Approaches to the Management and Treatment of Localized Prostate Cancer.

ABSTRACT: The aim of this study was to compare the cost-effectiveness and quality-adjusted life years (QALYs) of active monitoring (AM), radical prostatectomy (PR), and external-beam radiotherapy with neoadjuvant hormone therapy (RT) for localized prostate cancer. Microsimulations of radical prostatectomy, 3D-conformal radiotherapy, or active monitoring were performed using Medicare reimbursement schedules and clinical trial results for a target population of men aged 50-69 years with newly diagnosed localized prostate cancer (T1-T2, NX, M0) over a time horizon of 10 years. Quality-adjusted life years (QALYs) and costs were assessed and sensitivity analyses performed. Monte Carlo simulations revealed that the mean cost for AM, PR, and RT were $15,654, $18,791, and $30,378, respectively, and QALYs were 6.96, 7.44, and 7.9 years, respectively. The incremental cost-effectiveness ratio (ICER) was $6,548 for PR over AM and $68,339 for RT over PR. Results were sensitive to the number of years of follow-up and procedure cost. With relaxed assumptions for AM, the ICER of PR and RT met the societal willingness to pay (WTP) threshold of $50,000 per QALY. Compared with AM, PR was highly cost-effective. RT and PR for localized prostate cancer can be cost-effective, but RT must offer increased QALYs or decreased procedural costs to be cost-effective compared to PR. Newer and cheaper radiotherapy strategies like stereotactic body radiotherapy may play a crucial role in future early prostate cancer management.

Project description:ImportanceThe cost-effectiveness of different surgical techniques for radical prostatectomy remains a subject of debate. Emergence of recent critical clinical data and changes in surgical equipment costs due to their shared use by different clinical specialties necessitate an updated cost-effectiveness analysis in a centralized, largely government-funded health care system such as the UK National Health Service (NHS).ObjectiveTo compare robotic-assisted radical prostatectomy (RARP) with open radical prostatectomy (ORP) and laparoscopic-assisted radical prostatectomy (LRP) using contemporary data on clinical outcomes, costs, and surgical volumes in the UK.Design, setting, and participantsThis economic analysis used a Markov model developed to compare the cost-effectiveness of RARP, LRP, and ORP to treat localized prostate cancer. The model was constructed from the perspective of the UK NHS. The model simulated 65-year-old men who underwent radical prostatectomy for localized prostate cancer and were followed up for a 10-year period. Data were analyzed from May 1, 2020, to July 31, 2021.ExposuresRobotic-assisted radical prostatectomy, LRP, and ORP.Main outcomes and measuresQuality-adjusted life-years (QALYs), costs (direct medical costs and costs outside the NHS), and incremental cost-effectiveness ratios (ICERs).ResultsCompared with LRP, RARP cost £1785 (US $2350) less and had 0.24 more QALYs gained; thus, RARP was a dominant option compared with LRP. Compared with ORP, RARP had 0.12 more QALYs gained but cost £526 (US $693) more during the 10-year time frame, resulting in an ICER of £4293 (US $5653)/QALY. Because the ICER was below the £30 000 (US $39 503) willingness-to-pay threshold, RARP was more cost-effective than ORP in the UK. The most sensitive variable influencing the cost-effectiveness of RARP was the lower risk of biochemical recurrence (BCR). Scenario analysis indicated RARP would remain more cost-effective than ORP as long as the BCR hazard ratios comparing RARP vs ORP were less than 0.99.Conclusions and relevanceThese findings suggest that in the UK, RARP has an ICER lower than the willingness-to-pay threshold and thus is likely a cost-effective surgical treatment option for patients with localized prostate cancer compared with ORP and LRP. The results were mainly driven by the lower risk of BCR for RARP. These findings may differ in other health care settings where different thresholds and costs may apply.

Project description:BackgroundExternal beam radiotherapy is the recommended but expensive treatment option for localized prostate cancer. Prostate cancer is the most common cancer in men worldwide. A cost-effectiveness study is needed given the excessive cost of radiotherapy treatment and the high prevalence of prostate cancer. The aim of this systematic review was to assess and identify studies that examined model based economic evaluation of external beam radiation therapy for the treatment of localized prostate cancer.MethodsA systematic review of the published literature was conducted through MEDLINE, NHS EED (NHS Economic Evaluation Database), and Cochrane databases with a specific search strategy. The literatures were searched according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. At first 1046 citations were identified. The extracted files were imported into the Rayyan systematic review site for inclusion or exclusion based on the defined criteria. Studies included in this review were articles published between 2003 and 2017, and that conducted full-economic evaluations of the modality of external beam radiotherapy for the treatment of localized prostate cancer.ResultsThere were 12 studies that satisfied the inclusion and exclusion criteria. Seven studies compared intensity modulated radiation therapy (IMRT) with three-dimensional conformal radiation therapy (3D-CRT), two compared IMRT with stereotactic body radiation therapy (SBRT) another two-paper assessed IMRT with proton beam therapy (PBT). One paper compared the three external-beam radio therapy options of IMRT, SBRT and PBT. Most of the studies were originated from the US and analyzed the cost data from the payer's perspective. Most studies were supported that IMRT was cost effective when it compared with 3D-CRT. Compared with IMRT, SBRT was found to be cost-effective.ConclusionsThere are limited number of studies exist on the cost effectiveness of radiation therapy options for the treatment of localize prostate cancer across Europe. Most studies are originated from the US Medicare payer Perspective. Further research is need that investigate the cost effectiveness of these radiation therapy options from the societal perspective in Europe.

Project description:Knowledge of experiences from prostate cancer is sparse in a longitudinal perspective. From a nursing perspective, results from combined qualitative and quantitative studies are lacking however would present the broadest knowledge base for best practice. Present descriptions of medical-physical symptoms such as urinary, bowel and sexual dysfunction from quantitative inquiries need be complemented with qualitative results. Such knowledge is essential in relation to treatment and communication with patients over the years and not only shortly after surgery.A longitudinal study was formatted to investigate general and specific health quality and sense of coherence quantitative alterations over three years. A general health quality module (EORTC QLC-C30) and a disease-specific module (EORTC PR-25) were applied for the longitudinal study together with the Orientation to life questionnaire (SOC), measuring a persons' sense of coherence. In order to strengthen reliability and compensate for low participation we used the Directed content analysis for interviewing and analysis. The method allows using findings from earlier research when interviewing along with detecting new areas. Twenty-one men were followed over three years and six of them, in the third year, accepted to be interviewed.We found high quality of life ratings and extended the study with follow-up interviews in year three, to investigate whether questionnaire results were in line with interview findings. We found high life quality and functioning ratings that were in line with qualitative descriptions. Interview analysis showed retrieval of life as lived before, yet in a different way, the men never forgot the diagnosis event, had a unique illness history worth hearing, and had come to terms with most treatment-related shortcomings. Sense of coherence ratings were medium to high and confirmed stability over time in comprehensibility, manageability and meaningfulness after prostate cancer treatment.Over the years, the men's negative experiences from shifted into 'a good life' though in a different way than before. The interpretation is supported in the study by quantitative results showing a high degree of functioning. The men's sense of coherence seamed to support their handling of life three years after prostate cancer treatment.

Project description:BackgroundDiarrhoea is a leading cause of death in Nigerian children under 5 years. Implementing the most cost-effective approach to diarrhoea management in Nigeria will help optimize health care resources allocation. This study evaluated the cost-effectiveness of various approaches to diarrhoea management namely: the 'no treatment' approach (NT); the preventive approach with rotavirus vaccine; the integrated management of childhood illness for diarrhoea approach (IMCI); and rotavirus vaccine plus integrated management of childhood illness for diarrhoea approach (rotavirus vaccine + IMCI).MethodsMarkov cohort model conducted from the payer's perspective was used to calculate the cost-effectiveness of the four interventions. The markov model simulated a life cycle of 260 weeks for 33 million children under five years at risk of having diarrhoea (well state). Disability adjusted life years (DALYs) averted was used to quantify clinical outcome. Incremental cost-effectiveness ratio (ICER) served as measure of cost-effectiveness.ResultsBased on cost-effectiveness threshold of $2,177.99 (i.e. representing Nigerian GDP/capita), all the approaches were very cost-effective but rotavirus vaccine approach was dominated. While IMCI has the lowest ICER of $4.6/DALY averted, the addition of rotavirus vaccine was cost-effective with an ICER of $80.1/DALY averted. Rotavirus vaccine alone was less efficient in optimizing health care resource allocation.ConclusionRotavirus vaccine + IMCI approach was the most cost-effective approach to childhood diarrhoea management. Its awareness and practice should be promoted in Nigeria. Addition of rotavirus vaccine should be considered for inclusion in the national programme of immunization. Although our findings suggest that addition of rotavirus vaccine to IMCI for diarrhoea is cost-effective, there may be need for further vaccine demonstration studies or real life studies to establish the cost-effectiveness of the vaccine in Nigeria.

Project description:PurposeTo report prostate cancer outcomes, toxicity, and quality of life (QOL) in men treated with proton beam therapy (PBT).Patients and methodsPatients were enrolled in a prospective trial. All participants received 75.6 to 78 Gy (RBE). Up to 6 months of luteinizing hormone-releasing hormone agonist therapy was allowed. The Phoenix definition defined biochemical failure. Modified Radiation Therapy Oncology Group criteria defined toxicity. Expanded Prostate Cancer Index Composite questionnaires objectified QOL. Clinically significant QOL decrement was defined as ≥0.5 × baseline standard deviation.ResultsIn total, 423 men were analyzed. The National Comprehensive Cancer Network risk classification was used (low 43%; intermediate 56%; high 1%). At the 5.2-year median follow-up, overall and disease-specific survival rates were 99.8% and 100%, respectively. Cumulative biochemical failure rate was 5.2% (95% confidence interval [CI] = 3.0%-8.3%); acute grade 2 genitourinary (GU) toxicity was 46.3%; acute grade 2 gastrointestinal (GI) toxicity was 5.0% (95% CI = 3.1%-7.3%). There was no acute grade ≥3 GI or GU toxicity. Cumulative late grade 2 GU and GI toxicity was 15.9% (95% CI = 13%-20%) and 9.7% (95% CI = 6.5%-12%), respectively. There were 2 grade 3 late GI toxicities (rectal bleeding) and no late grade ≥3 GU toxicity. The 4-year mean Expanded Prostate Cancer Index Composite urinary, bowel, sexual, and hormonal summary scores (range; standard deviation) were 89.7 (43.8-100; 11), 91.3 (41.1-94.6; 10), 57.8 (0.0-96.2; 27.1), and 92.2 (25-95.5; 10.5), respectively. Compared with baseline, there was no clinically significant decrement in urinary, sexual, or hormonal QOL after treatment completion. A modest (<10 points), yet clinically significant, decrement in bowel QOL was appreciated throughout follow-up.ConclusionContemporary PBT resulted in excellent biochemical control, minimal risk of higher-grade toxicity, and modest QOL decrement. Further investigation comparing PBT with alternative prostate cancer treatment strategies are warranted.

Project description:IntroductionRadiotherapy can diminish quality of life (QoL) for prostate cancer patients. Our objective was to evaluate the effect of radiotherapy on QoL in men aged 75 years or older treated with radiotherapy for a localized prostate cancer, and to identify predictors of reduced QoL.Patients and methodsWe prospectively administered a battery of geriatric (MNA, GDS, Get up and Go Test, CIRS-G, ADL, IADL, MMSE), toxicity (IPSS; IIEF 5), and QoL (QLQ C30) screening tests in 100 elderly patients before and two months after prostate cancer radiotherapy (NCT 02876237). Patients ≥ 75 years undergoing radiotherapy with a curative intent for localized prostate cancer with or without androgen deprivation therapy (ADL) were eligible for study inclusion. Correlations between patient-assessed QoL and tumor characteristics, radiotherapy treatment or CGA parameters were sought using the Fisher or the Mann and Whitney tests. Changes in QoL parameters over time were analyzed using the Wilcoxon signed-rank test.ResultsAt study entry, scores for IADL impairments were present in 51%, reduced autonomy in activities of daily living in 16%, cognitive impairment found in 20%, depression-related symptoms in 31%, and 66% of patients had significant co-morbidities. Eight percent were judged to be at risk of fall and 2% were found to be undernourished. Severely impaired (IPSS ≥ 20) urinary function was observed in 11.2% and 13.5% of patients before and two months after completion of radiotherapy respectively. Significantly decreased QoL (> 20 points) at two months after treatment was found in 13% of patients and a moderate but clinically relevant reduction (10 to 20 points) in 17% of patients. No tumor characteristic, treatment, or oncogeriatric parameter was predictive of reduced QoL following prostate cancer radiotherapy.ConclusionDespite sometimes markedly diminished oncogeriatric parameters, prostate cancer radiotherapy was generally well tolerated in these elderly patients. We found no predictive factor to determine which patients would experience impaired quality of life following radiotherapy.
