Cost items in melanoma patients by clinical characteristics and time from diagnosis.

Background: Costs related to the care of melanoma patients have been rising over the past few years due to increased disease incidence as well as the introduction of innovative treatments. The aim of this study is to analyse CMM cost items based on stage at diagnosis, together with other diagnostic and prognostic characteristics of the melanoma. Methods: Analyses were performed on 2,647 incident cases of invasive CMM that were registered in 2015 and 2017 in the Veneto Cancer Registry (RTV). Direct melanoma-related costs per patient were calculated for each year ranging from 2 years before diagnosis to 4 years after, and were stratified by cost items such as outpatient services, inpatient drug prescriptions, hospital admissions, hospice admissions, and emergency room treatment. Average yearly costs per patient were compared according to available clinical-pathological characteristics. Lastly, log-linear multivariable analysis was performed to investigate potential cost drivers among these clinical-pathological characteristics. Findings: Overall, the average direct costs related to melanoma are highest in the first year after diagnosis (€2,903) and then decrease over time. Hospitalization costs are 8 to 16 times higher in the first year than in subsequent years, while the costs of outpatient services and inpatient drugs decrease gradually over time. When stratified by stage it is observed that the higher expenditure associated with more advanced stages of CMM is mainly due to inpatient drug use. Conclusion: The results of the present study show that grouping patients according to tumour characteristics can improve our understanding of the different cost items associated with cutaneous malignant melanoma. CMM patients experience higher costs in the first year after diagnosis due to higher hospitalization and outpatient services. Policy makers should consider overall and stage-specific annual costs when allocating resources for the management of CMM patients.

Sex Differences in Soft Tissue Sarcoma: Incidence, Clinicopathological Profile, Survival, and Costs.

Background: There are evident sex differences in the incidence of and mortality rates for several tumors. Soft tissue sarcomas (STSs) account for no more than 1% of all malignancies in adults. This study aimed to provide a comprehensive overview of the sex differences in the epidemiology of STSs and the related costs. Methods: This retrospective population-based study draws on epidemiological data regarding cases of STS collected by the cancer registry of the Italian Veneto region for the years 1990-2018. A joinpoint regression analysis was performed to identify significant changes in the trends of the standardized incidence rates in males and females. Bivariate and survival analyses were conducted to assess differences in clinicopathological characteristics and short-term mortality by sex. Direct health care costs incurred over 2 years after a diagnosis of STS were calculated, stratified by sex. Results: The incidence rates of STS at any age were higher for males; only among males the incidence rates showed a tendency to slightly increase. No significant sex differences came to light in short-term mortality or clinicopathological profile, except for the cancer site. Health care costs in the 2 years after a diagnosis of STS were not sex related. Conclusion: The STS incidence was found to be higher for males and showed a rising trend over the last three decades only for males. These findings could result from the occupational exposure to environmental mutagens mainly involving men. Sex did not affect the survival or the clinicopathological STS profile.

Direct Costs of Care for Adults with Soft Tissue Sarcomas: A Population-Based Study.

The clinical treatment of soft tissue sarcoma (STS) has evolved substantially over the last decade. This population-based cohort study based on real-world data included all incidental STS recorded by the Veneto Cancer Registry in 2017. Data on hospital admissions, emergency department and outpatient visits, drug prescriptions, and use of medical devices within two years from STS diagnosis were obtained from administrative databases. The average per-patient real-world costs over this two-year period, in total and by single expenditure item, were calculated and stratified by stage of disease at diagnosis, tumor histology and tumor site. The mean total cost per patient amounted to EUR 16,793. A higher TNM stage at diagnosis was associated with higher healthcare costs, as follows: compared with stage I, the average total cost per patient was 1.32, 2.18 and 3.36 times greater for stages II, III and IV, respectively. Hospital stays generated the greatest costs (averaging EUR 7950 per patient), followed by outpatient visits (mean EUR 3947 per patient) and drug prescriptions (mean EUR 3664 per patient). Given the paucity of population-based studies, the present results can serve as a reference for further cost-effectiveness analyses on care strategies for patients with STS.

Malignant Melanoma: Direct Costs by Clinical and Pathological Profile.

INTRODUCTION: A number of studies have examined the impact of tumor stage on direct health care costs of patients with melanoma. This study aimed to investigate the association between the direct costs for melanoma and the patients' clinical and histological characteristics. METHODS: The present analysis included 1368 patients diagnosed with melanoma in 2017 in the Veneto Region (northeast Italy) and recorded in a regional population-based melanoma registry. The costs were assessed taking monthly and total direct costs into account. Log-linear multivariable analysis was used to identify the clinical and histological cost drivers, focusing on monthly and total direct costs per patient incurred during the first 2 years after a patient's diagnosis. RESULTS: On multivariable analysis, besides the stage of melanoma, also the presence of mitoses (> 2) was associated with higher monthly direct costs [odds ratio (OR) 1.55, 95% confidence interval (CI) 1.15-2.08, p = 0.004] in respect to cases with 0-2 mitoses. Vertical growth was associated with higher costs compared with radial growth (OR 1.28, 95% CI 1.00-1.64, p = 0.055). Moreover, the association between the absence of tumor-infiltrating lymphocytes (TILs) and higher monthly direct costs reached statistical significance (OR 1.31, 95% CI 1.05-1.64, p = 0.017). There were no differences in monthly direct costs by patients' sex or age, ulceration, or tumor site. CONCLUSION: This study showed that not only tumor stage but also other clinical and histopathologic characteristics have an impact on the direct monthly and total costs of treating melanoma. Further studies on the cost-effectiveness of the various options for managing this disease should take these variables into account, as well as tumor stage, as cost drivers.

Sex Differences in Cutaneous Melanoma: Incidence, Clinicopathological Profile, Survival, and Costs.

Background: This study aims to provide a comprehensive overview of sex-related characteristics of cutaneous malignant melanoma (CMM), with special reference to its incidence, clinicopathological profile, overall survival, and treatment-related costs. Methods: This retrospective cohort study included all 1,279 CMM patients who were registered in 2015 in the Veneto Cancer Registry (a population-based registry including all 4,900,000 regional residents). The by-sex comparisons included tumor stage and site, histological subtype, and other clinical-pathological variables. A Cox regression analysis was used to test the association between sex and survival, adjusting for the main covariates. Treatment costs were calculated by linking patients with several administrative regional databases. Results: Age-specific incidence rates were significantly higher for men among people >50 years old. For men, the trunk was the most common primary site (59.3%), whereas for women the lower limbs (32.1%) were the most common primary site, followed by the trunk (31.8%), which was lower than for men (p < 0.001). At presentation, the frequency of early stage CMM was higher among women, who also featured a significantly lower risk of death (p = 0.016), after adjusting for covariates. Men also incurred higher costs for melanoma treatment in the first year after their diagnosis. Conclusions: Among younger adults, CMM was more common in women, whereas among older adults, it was more common in men. Sex also influences patients' histopathological characteristics at diagnosis. Women had better overall survival after adjusting for demographic, pathological, and clinical profiles. The costs of treatment were also lower for women with CMM.

Quality management of cutaneous melanoma: impact on short-term outcomes and costs.

Promoting standardization and quality assurance (QA) may guarantee better outcomes for patients and ensure a better allocation of healthcare system resources. The present study tested the association between process quality indicators of the clinical pathway for melanoma and both patient short-term mortality and budget utilization. Specific indicators were selected to assess quality of processes in different phases of the pathway as well as the pathway as a whole. Cox regression models were run for each phase to test the association between adherence to the quality indicator and overall mortality. A Tobit regression analysis was used to identify any association between adherence to the quality indicators and total costs over the two years after melanoma was diagnosed. This retrospective cohort study concerned 1,222 incident cases of melanoma in the Veneto Region (north-east of Italy). Adherence to the clinical pathway as a whole was associated with a significant decrease in risk of death (HR= 0.40; 95% CI: 0,19 -0,77). Adherence to quality processes in the diagnostic phase (HR= 0.55 95% CI: 0.31- 0.95) and surgical phase (HR= 0.33 95% CI: 0.16- 0.61) significantly reduced the hazard risk. Tobit regression revealed a significant increase in overall costs for patients who adhered to the whole pathway in comparison with those who did not (ß= 2,393.24; p= 0.013). This study suggests that adherence to the quality of management of clinical pathways modifies short-term survival as well as mean cost of care for patients with cutaneous melanoma. Physicians should be encouraged to improve their compliance with clinical care pathways for their melanoma patients, and steadily growing associated costs emphasize the need for policy makers to invest exclusively in treatments of proven efficacy.

Differences in direct costs of patients with stage I cutaneous melanoma: A real-world data analysis.

BACKGROUND: Clinical factors, such as tumor thickness, ulceration and growth phase have a role as prognostic factors for stage I melanoma. However, it is still under debate whether these variables influence the related direct costs. We aimed to investigate which clinical factors represent direct health care "cost drivers" for stage I melanoma. MATERIALS AND METHOD: Analyses were conducted on a cohort of patients diagnosed with stage I melanoma. Differences in the costs incurred by different groups of patients were examined using Mann-Whitney or Kruskal-Wallis non-parametric tests. Log linear multivariate analysis was used to identify the clinical drivers of the total direct costs one and two years after diagnosis. The study was conducted from the perspective of Italy's National Health care System. RESULTS: One year after diagnosis, patients whose melanomas had a Breslow thickness ≥0.8 mmin (compared with those with lower thickness) and a vertical growth phase (compared with those with radial growth) incurred higher costs for hospitalization, as well as higher overall costs. One year after their diagnosis, treatment of patients with stage I melanoma in the vertical growth phase costs 50% more (95% CI: 22-85%) than their counterparts with a radial growth pattern, resulting in an estimated absolute increase of € 256.23. Having a tumor thicker than 0.8 mm prompted an increase of 91% (95% CI: 43-155%) in the costs (€955.24 in absolute terms). CONCLUSION: Our data indicate a heterogeneity in the direct costs of stage I melanoma patients during the first year after diagnosis, which can be partly explained by clinical prognostic factors, like tumor thickness and growth pattern.

Estimation of direct costs of melanoma in the Veneto Region: a budget assessment and cost-consequence analysis.

BACKGROUND: While many evidence-based pathways have been introduced to drive quality improvements in cancer care, most of these do not include evidence about their affordability. The main aim of this study was to provide an estimation of the overall budget to cover all the needs of melanoma patients in Veneto Region, managed according to the clinical pathway defined by the Rete Oncologica Veneta. A second objective is to conduct a cost-consequence analysis, comparing two different treatments. METHODS: A very detailed whole-disease model was developed describing the patient's pathway from diagnosis through the first year of follow-up. Each procedure involved in the model was associated with a likelihood measure and a cost. The model can be used to estimate the expected direct costs associated with melanoma. RESULTS: We can observe that 0 and I stage, despite accounting for a huge percentage of new melanoma cases are characterized by a small percentage of the total costs. Stage III can be considered as the most expensive stage accounting for 54% of the total costs with a 12% of patients. Finally, the stage IV patients, although very few accounts for almost the 7% of the total costs. Regarding the cost-consequence analysis, it was estimated that the therapies introduced in 2016 led to an approximately 14% increase in the total costs. CONCLUSIONS: Modeling a clinical pathway with a high level of detail enables to identify the main sources of spending. The consequent analysis can thus help policymakers to plan the future resources allocation.

Estimation of Direct Melanoma-related Costs by Disease Stage and by Phase of Diagnosis and Treatment According to Clinical Guidelines.

Cutaneous melanoma is a major concern in terms of healthcare systems and economics. The aim of this study was to estimate the direct costs of melanoma by disease stage, phase of diagnosis, and treatment according to the pre-set clinical guidelines drafted by the AIOM (Italian Medical Oncological Association). Based on the AIOM guidelines for malignant cutaneous melanoma, a highly detailed decision-making model was developed describing the patient's pathway from diagnosis through the subsequent phases of disease staging, surgical and medical treatment, and follow-up. The model associates each phase potentially involving medical procedures with a likelihood measure and a cost, thus enabling an estimation of the expected costs by disease stage and clinical phase of melanoma diagnosis and treatment according to the clinical guidelines. The mean per-patient cost of the whole melanoma pathway (including one year of follow-up) ranged from €149 for stage 0 disease to €66,950 for stage IV disease. The costs relating to each phase of the disease's diagnosis and treatment depended on disease stage. It is essential to calculate the direct costs of managing malignant cutaneous melanoma according to clinical guidelines in order to estimate the economic burden of this disease and to enable policy-makers to allocate appropriate resources.
