- Abstract
Background: Population-based survival and costs of pancreas adenocarcinoma patients receiving adjuvant chemoradiation and chemotherapy following pancreaticoduodenectomy are poorly understood. Methods: This retrospective cohort study used linked administrative and pathological datasets to identify all patients diagnosed with pancreas adenocarcinoma and undergoing pancreaticoduodenectomy in Ontario between April 2004 and March 2014, who received postoperative chemoradiation or chemotherapy. Stage and margin status were defined by using pathology reports. Kaplan–Meier and Cox proportional hazards regression survival analyses were used to determine associations between adjuvant treatment approach and survival, while stratifying by margin status. Median overall health system costs were calculated at 1 and 3 years for chemoradiation and chemotherapy, and differences were tested using the Kruskal–Wallis test. Results: Among 709 patients undergoing pancreaticoduodenectomy for pancreas cancer during the study period, the median survival was 21 months. Median survival was 19 months for chemoradiation and 22 months for chemotherapy. Patients receiving chemoradiation were more likely to have positive margins: 47.7% compared with 19.2% in chemotherapy. After stratifying by margin status and controlling for confounders, adjusted hazard ratio of death were not statistically different between chemotherapy and chemoradiation [margin positive, hazard ratio (HR) = 0.99, 95% confidence interval (CI) = 0.88–1.27; margin negative, HR 0.95, 95% CI 0.91–1.18]. Overall 1-year health system costs were significantly higher for chemoradiation (USD $70,047) than chemotherapy (USD $54,005) (p ≤ 0.001). Conclusions: Chemotherapy and chemoradiation yielded similar survival, but chemoradiation resulted in higher costs. To create more sustainable healthcare systems, both the efficacy and costs of therapies should be considered. [ABSTRACT FROM AUTHOR]

Background: Rising health care costs have led to increasing focus on cost containment and accountability from health care providers. We sought to explore surgeon awareness of supply costs for open and laparoscopic distal gastrectomy. Methods: Surveys were sent in 2015 to surgeons at 8 academic hospitals in Toronto who performed distal gastrectomy for gastric adenocarcinoma. Respondents were asked to estimate the total cost, type and number of disposable equipment pieces required to perform open and laparoscopic distal gastrectomy. We determined the accuracy of estimates through comparisons with procedural invoices for distal gastrectomy performed between Jan. 1, 2011, and Dec. 31, 2015. All values are in 2015 Canadian dollars. Results: Of the 53 surveys sent out, 12 were completed (response rate 23%). Surgeon estimates of total supply costs ranged from $500 to $3000 and from $1500 to $5000 for open and laparoscopic cases, respectively. Estimated supply costs for requested equipment ranged from $464 to $2055 for open cases and from $1870 to $2960 for laparoscopic cases. Invoices for actual equipment yielded a mean of $821 (standard deviation $543) (range $89–$2613) for open cases and $2678 (standard deviation $958) (range $835–$4102) for laparoscopic cases. Estimates of total cost were within 25% of the median invoice total in 1 response (9%) for open cases and 3 (27%) of those for laparoscopic cases. Conclusion: Respondents failed to accurately estimate equipment costs. The variation in true total costs and estimates of supply costs represents an opportunity for intraoperative cost minimization, efficient equipment selection and value-based purchasing arrangements.

Background: The single-payer universal health care system in Ontario, Canada creates a setting with reduced socioeconomic barriers to treatment. Herein, the authors sought to elucidate the influence of sociodemographic marginalization on receipt of pancreatectomy, overall survival (OS), and receipt of adjuvant treatment among patients diagnosed with pancreatic cancer at the population level using an observational cohort study design.Methods: Patients diagnosed with pancreatic cancer in Ontario between January 2005 and January 2010 were identified using the provincial cancer registry and linked to administrative databases. Census data obtained from each patient's postal code were used as a proxy for that patient's median income, residential instability, material deprivation, ethnic concentration, and dependency (percentage aged <15 years, aged >65 years, and unemployed). Surgical specimen pathology reports were abstracted for histopathology and margin status. Independent predictors of undergoing pancreatectomy, OS after surgical resection, and receipt of adjuvant treatment were identified by logistic regression and Cox proportional hazards analysis.Results: Of the 6296 patients diagnosed with pancreatic cancer, 820 (13%) underwent resection of their tumor. Increasing levels of residential instability (odds ratio [OR], 0.86; 95% confidence interval [95% CI], 0.80-0.94) and material deprivation (OR, 0.86; 95% CI, 0.79-0.94) predicted a decreased likelihood of undergoing surgical resection. Patients living in rural areas (OR, 0.68; 95% CI, 0.51-0.91) and those living in urban areas with lower incomes (OR range, 0.49-0.77) were found to have a lower likelihood of undergoing surgical resection compared with patients in the urban areas with the highest income. After surgical resection, an association between sociodemographic marginalization with OS or receipt of adjuvant treatment was not identified.Conclusions: Sociodemographic marginalization exerts its influence early in the pancreatic cancer care continuum, and appears to be associated more with which patients undergo surgical resection than the receipt of adjuvant treatment.

- Abstract
Background: In recent years, the FDA has approved several 3-agent (i.e., triplet) combinations for previously treated multiple myeloma (MM), and the National Comprehensive Cancer Network (NCCN) now recommends triplet regimens over doublets. Little is known about the real-world cost of triplet combinations because of the limited time that they have been on the market since FDA approval. Furthermore, traditional cost analyses developed to support market entrance rely on utilization assumptions that are difficult to validate when numerous comparators simultaneously enter the market., Objective: To perform a 1-year cost analysis of novel triplets used for the treatment of patients with previously treated MM controlling for differences in utilization., Methods: FDA-approved, NCCN-recommended (preferred and category 1 for previously treated MM) treatments included in the analysis were daratumumab plus lenalidomide plus dexamethasone (DARA/LEN/DEX), daratumumab plus bortezomib plus dexamethasone (DARA/BOR/DEX), elotuzumab plus lenalidomide plus dexamethasone (ELO/LEN/DEX), carfilzomib plus lenalidomide plus dexamethasone (CAR/LEN/DEX), and ixazomib plus lenalidomide plus dexamethasone (IXA/LEN/DEX). To control for market uptake, the model was designed to estimate the cost of treating an average patient over a 1-year time horizon. Drug administration and dosing, required comedications, postprogression therapy, monitoring requirements, and adverse event (AE) rates were based on FDA prescribing information or clinical trials. AEs ≥ grade 3 that occurred in ≥ 5% of patients were included. RED BOOK wholesale acquisition costs were used for drug acquisition costs. Costs of drug administration, AE management, and patient monitoring were based on the 2018 Center for Medicare & Medicaid Services payment rates or from published literature (inflated to 2018 U.S. dollars). The treatment duration for each regimen was estimated from modeled progression-free survival data; the 12-month progression-free survival rate was assumed to be equivalent to the probability that an average patient remained on therapy for at least 1 year after treatment initiation, which was used to estimate time-depended treatment-related costs. The probability of progression within 1 year of treatment initiation was used to inform the average postprogression therapy costs for each regimen., Results: The estimated cost per patient for each triplet regimen was $13,890 (DARA/BOR/DEX), $22,231 (IXA/LEN/DEX), $24,322 (ELO/LEN/DEX), $26,410 (DARA/LEN/DEX), and $27,432 (CAR/LEN/DEX). Drug acquisition costs and treatment duration were the largest drivers of cost. Scenario analyses with plausible alternative input parameters found the maximum per month cost of therapy to be $30,657 (CAR/LEN/DEX) and the minimum per month cost of therapy to be $13,784 (DARA/BOR/DEX)., Conclusions: This analysis controlled for differential utilization rates for 5 FDA-approved, NCCN-recommended triplet therapies for the treatment of previously treated MM. Of the examined regimens, treatment with DARA/BOR/DEX was estimated to have the lowest average monthly cost per patient, while CAR/LEN/DEX was the most expensive. As is common with modeling, some assumptions were necessary, and results may not be generalizable., Disclosures: This study was funded by Janssen Scientific Affairs, which employs Maiese and funded Cornerstone Research Group, a health economic consulting group, to complete the cost analysis, interpret data, and develop the manuscript. Janssen was involved in the design of the analysis, interpretation of results, and manuscript development and approval. Grima is a founding partner of Cornerstone Research Group, which employs Hollmann, Goyert, and Moldaver. Hollmann, Goyert, and Moldaver were responsible for creation of the economic model.
