Economic evaluation of trifluridine and tipiracil hydrochloride in the treatment of metastatic colorectal cancer in Greece.

AIM: To evaluate the cost-effectiveness of trifluridine and tipiracil hydrochloride (FTD/TPI) compared with best supportive care (BSC) or regorafenib for the treatment of patients with metastatic colorectal cancer who have been previously treated with or are not considered candidates for available therapies including fluoropyrimidine-, oxaliplatin- and irinotecan-based chemotherapies, anti-VEGF agents and anti-EGFR agents in Greece. METHODS: A partitioned survival model was locally adapted from a third-party payer perspective over a 10 year time horizon. Efficacy data and utility values were extracted from published studies. Resource consumption data were obtained from local experts using a questionnaire developed for the purpose of the study and was combined with unit costs obtained from official sources. All costs reflect the year 2017 in euros. Primary outcomes were patients' life years (LYs), quality-adjusted life years (QALYs), total costs and incremental cost-effectiveness ratios (ICERs) per QALY and LYs gained. RESULTS: Total life time cost per patient for FTD/TPI, BSC and regorafenib was estimated to be €10,087, €1,879 and €10,850, respectively. In terms of health outcomes, FTD/TPI was associated with 0.25 and 0.11 increment in LYs compared with BSC and regorafenib, respectively. Furthermore, FTD/TPI was associated with 0.17, and 0.07 increment in QALYs compared with BSC and regorafenib, resulting in ICERs of €32,759 per LY gained and €49,326 per QALY gained versus BSC. Moreover, FTD/TPI was a dominant alternative over regorafenib. CONCLUSION: The results indicate that FTD/TPI may represent a cost-effective treatment option compared with other alternative therapies as a third-line treatment of metastatic colorectal cancer in Greece.

Cyclosporine minimization and cost reduction in renal transplant recipients receiving a C2-monitored, cyclosporine-based quadruple immunosuppressive regimen.

BACKGROUND: Targeting 2-hr postdose cyclosporine (C2) levels to 1,000 to 1,700 mg/dL during the first 6 months after renal transplantation is recommended for triple immunosuppressive regimens. This trial determines whether lower C2 levels could be targeted safely in de novo kidney transplant recipients under a quadruple regimen compared with a similar cohort monitored with trough (C0) levels. METHODS: This single-center, sequential, cohort-designed trial included patients who received Thymoglobulin, corticosteroids, an antimetabolite, and cyclosporine monitored by C2 (n=50) or C0 (n=50). Cyclosporine was tapered to maintain the C2 between 1,000 and 1,200 ng/mL months 0 to 3 and between 600 and 1,000 ng/mL thereafter and C0 between 250 and 350 ng/mL months 0 to 3 and between 100 and 250 ng/mL thereafter. RESULTS: Baseline patient and donor characteristics were similar. There were no differences in graft survival (100% C2 vs. 100% C0), acute rejection (4% C2 vs. 6% C0), allograft function, or adverse events at 6 months. C2 levels were lower than the suggested guidelines throughout the study (33% lower at 1 month and 48% lower at 6 months). Lower cyclosporine doses were achieved in the C2 arm compared with the C0 arm by 1 month and were sustained throughout the trial, which translated into an average cyclosporine cost savings of USD $773 in the C2 arm during the 6-month period (P<0.001). CONCLUSION: With a quadruple immunosuppressive regimen and lower C2 targets than recommended for triple therapy, safe and effective cyclosporine minimization was achieved. Lower cyclosporine doses were achieved in C2-monitored patients compared with C0-monitored patients, translating into lower immunosuppressive costs.

Cost analysis of secondary prophylaxis with oral clodronate versus pamidronate in metastatic breast cancer patients.

OBJECTIVE: We compared the direct medical costs of secondary prophylaxis with bisphosphonates (BPs) in bone metastases (BMs) of breast cancer (BCa) from a payer perspective. PATIENTS AND METHODS: This study adopted an incidence-based chart review of consecutive BCa patients with BMs who received prophylactic treatment with orally administered (po) clodronate (CLODpo group), or intravenously administered (iv) pamidronate (PAM group) in 1997 at two large oncology centers in Toronto, Ontario. We evaluated the difference in costs of management of patients among the CLODpo and PAM groups using an intent-to-treat analysis from diagnosis of BMs to death, or last follow-up. The results are presented as observed mean and average lifetime (including terminal care) costs per patient. RESULTS: The observed mean costs in the PAM and CLODpo groups were 49,472 dollars and 50,307 dollars (2002 Canadian dollars), respectively. The difference in costs between the CLODpo (n=34) and PAM (n=18) groups was not significant (P=0.64), and remained robust after sensitivity analyses. The corresponding average lifetime costs were 65,677 dollars in the CLODpo group and 61,254 dollars in the PAM group. Inpatient and terminal care were the major cost drivers, comprising 45% and 25% of overall costs. Of all hospitalizations, 46% were associated with complications from BMs. CONCLUSIONS: Our analysis, which was based on a convenience sample, failed to reveal a statistically significant difference in the observed mean costs between groups of patients who initiated treatment with po clodronate versus iv pamidronate. The cost estimates from this study can be used for future corroborative economic analyses.

Treating Bowen's disease: a cost-minimization study.

BACKGROUND: In the current economic climate, it is important to justify the cost of treatments used in dermatology, particularly where cheaper alternatives exist. OBJECTIVES: To determine which treatment modality commonly used for Bowen's disease is associated with the lowest cost to the National Health Service. METHODS: A cost-minimization analysis was used to compare the following six treatments for Bowen's disease: cryotherapy, curettage and cautery, excision, laser ablation, photodynamic therapy and 5-fluorouracil. These are all known to have similar recurrence rates. Information regarding use of these treatment modalities was extracted from a literature review. Costs were determined from published data, average wholesale prices of medications, staff salary pay scales and health economics departments. RESULTS: The results show that, if treatment is indeed undertaken, a single lesion of Bowen's disease is most cheaply treated by curettage or excision biopsy under local anaesthetic, and most expensively treated by photodynamic therapy. The usefulness of this information has to be taken in the context of the study design, outcome measurements and base assumptions. CONCLUSIONS: Valid costing studies such as this, in conjunction with evidence of effectiveness and safety, can provide guidance for resource allocation and treatment decisions.
