Background: The use of 1-year mortality following pancreatectomy for PDAC as a measure of surgical quality has not been evaluated. We aim to i) assess the 1-year mortality rate following pancreatectomy for PDAC, and ii) identify patient and hospital characteristics associated with 1-year mortality., Methods: Data was extracted retrospectively from the French national medico-administrative database. The study included patients who underwent pancreatectomy for PDAC between January 2012 and December 2019. The primary outcome was 1-year postoperative mortality. Hospitals were classified based on volume (high (≥26 resections/year) and low volume (<26))., Results: Overall, 17,183 patients who underwent pancreatectomy for PDAC were included. The overall 90-day and 1-year mortalities were 6.5 % and 21.5 %, respectively. 1-year mortality varied significantly between low and high-volume hospitals (23.6 % vs. 18.6 %, respectively, p < 0.001). Older age, Charlson Comorbidity Index (CCI), readmission, major complications were predictive factors for 1-year mortality. Pancreatectomy in low volume hospitals increased the risk of 1-year mortality by 1.23-fold (OR = 1.23, 95 % CI [1.15-1.32], p < 0.001)., Conclusion: The overall 1-year mortality after pancreatectomy for PDAC was 21.5 %, and was higher in patients of older age, with higher comorbidities, who experienced major complications, and who did not receive adjuvant therapy. Management in high-volume centers decreased mortality rates, regardless of the patient's condition., Competing Interests: Declaration of competing interest None declared., (Copyright © 2024 International Hepato-Pancreato-Biliary Association Inc.

Background: Data on clinically relevant post-pancreatectomy hemorrhage (CR-PPH) are derived from series mostly focused on pancreatoduodenectomy, and data after distal pancreatectomy (DP) are scarce., Methods: All non-extended DP performed from 2014 to 2018 were included. CR-PPH encompassed grade B and C PPH. Risk factors, management, and outcomes of CR-PPH were evaluated., Results: Overall, 1188 patients were included, of which 561 (47.2 %) were operated on minimally invasively. Spleen-preserving DP was performed in 574 patients (48.4 %). Ninety-day mortality, severe morbidity and CR-POPF rates were 1.1 % (n = 13), 17.4 % (n = 196) and 15.5 % (n = 115), respectively. After a median interval of 8 days (range, 0-37), 65 patients (5.5 %) developed CR-PPH, including 28 grade B and 37 grade C. Reintervention was required in 57 patients (87.7 %). CR-PPH was associated with a significant increase of 90-day mortality, morbidity and hospital stay (p < 0.001). Upon multivariable analysis, prolonged operative time and co-existing POPF were independently associated with CR-PPH (p < 0.005) while a chronic use of antithrombotic agent trended towards an increase of CR-PPH (p = 0.081). As compared to CR-POPF, the failure-to-rescue rate in patients who developed CR-PPH was significantly higher (13.8 % vs. 1.3 %, p < 0.001)., Conclusion: CR-PPH after DP remains rare but significantly associated with an increased risk of 90-day mortality and failure-to-rescue., (Copyright © 2023 International Hepato-Pancreato-Biliary Association Inc.

Introduction: Total alkaline phosphatase (tALP) levels rise physiologically in maternal serum during pregnancy, and excessively so in certain conditions. However, current reference values are dated, nonlinear, and based on small samples. Factors related to variation in tALP remain unexplained. Thus, our goals in this study were to establish a physiological development curve for tALP within low-risk pregnancies and to evaluate the factors influencing tALP values., Methods: This was a single-center, retrospective, observational study. All patients who delivered a live singleton infant at our center from January 1, 2011 to May 31, 2019, and had a tALP assay during pregnancy, were included regardless of the gestational age at which the assay was conducted., Results: A total of 2415 pregnancies were included. Median tALP decreased during the first trimester, it increased slightly during the second trimester, and then increased sharply during the third trimester. Factors associated with a significant increase in tALP were chronic histiocytic intervillositis, cholestasis, multiple pregnancies, liver disease, preeclampsia, smoking, and low weight for gestational age. Conversely, gestational diabetes was associated with a discrete decrease in tALP., Discussion: Our large sample allowed establishment of tALP reference curves based on gestational age. To interpret these results more thoroughly, factors that influence tALP rates should be further scrutinized., Competing Interests: Declarations of competing interest None., (Copyright © 2022.

Background & Aims: The use of long-term taurolidine locks (LTTL) seems to be effective in preventing catheter-related blood stream infections (CRBSI), especially in patients on home parenteral nutrition (HPN). This work targets the cost-effectiveness of LTTL in a cohort of adult HPN patients., Methods: A monocentric mirror-image design study was conducted in our referral centre among long-term HPN patients experiencing recurrent CRBSI. From 7th January 2011, LTTL were started after the third CRBSI episode within 12 months. CRBSI data was prospectively collected until 7th January 2013, in the same way as it had retrospectively been done before initiating LTTL. A cost-effective analysis was conducted to estimate the incremental costs and effects on CRBSI with LTTL. The efficacy of LTTL on CRBSI rate was assessed over 1000 days of catheter use., Results: A total of 31,100 catheter days were analysed in 37 patients (median [interquartile range (IQR)]) aged 58 [42-68] years. The mean ± SD proven CRBSI rate was 3.18 ± 3.51 per 1000 catheter days before the introduction of LTTL and 0.39 ± 1.50 per 1000 catheter days after its introduction (p < 0.0001). Considering both proven and probable CRBSI requiring hospital management, LTTL reduced by (mean [bootstrap CI 95%]) -2.63 [-3.26 to -2.06] infections per patient (from 2.89 [2.31 to 3.49] before to 0.26 [0.13 to 0.41] after) as well as incremental costs by -7 258 [-10 450 to -4 016] € (from 11 176 [8 004 to 14 968] € before to 3 918 [2 390 to 5 445] € after)., Conclusion: Implementing LTTL to prevent recurrent CRBSI is cost-effective by dramatically decreasing their incidence., Competing Interests: Conflict of interest The authors declare that they have no conflict of interest concerning this article., (Copyright © 2021 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Background: It remains to be established whether centralization to high volume centers is essential for all patients undergoing pancreatic surgery. The aims of this study were to identify the optimal cut-off volume to optimize patient outcomes and to determine if patient comorbidity affected the volume-outcome relationship., Methods: Patients undergoing pancreatectomy from 2012 to 2015 were retrospectively identified (n = 12 333) in the French nationwide database. The 90-day Post-Operative Mortality (POM) was analyzed according to hospital volume of pancreatectomy (very low:<10, Low:10-19, High:20-49 and very high:≥50 resections/year) and Charlson Comorbidity Index (ChCI)., Results: The overall POM was 6.9%. The cut-off of 20 pancreatic resections per year was identified as predictor of POM. Compared to high volume centers, POM was significantly higher in low and very low volume centers whatever the ChCl. Regarding surgical procedures, there was a significant decrease in POM with increasing hospital volume only after pancreaticoduodenectomy regardless of the ChCl. On multivariable analysis, low and very low volume centers were independently associated with increased mortality rates., Conclusion: The optimal cut-off of annual caseload was 20 pancreatic resections. POM following pancreaticoduodenectomy is high in low and very low volume centers independently of ChCl, suggesting that this procedure should be centralized., (Copyright © 2019.

Background: The aim of the study was to assess the incremental cost-effectiveness ratio (ICER) of the FEC 100 compared with the FEC 50 in the FASG05 trial., Materials and Methods: A cost-effectiveness analysis was performed using a multi-state Markov process model. Relevant clinical data introduced into the model were obtained from 10-year follow-up of the clinical trial FASG05. Survival curves for each health state were assessed by survival parametric model. The model allowed assessments from the start of adjuvant chemotherapy until death. The costs of adjuvant treatment and follow-up were estimated. The costs of recurrence were evaluated from the medical records of 146 patients. A prospective survey was performed on a cohort of 87 patients to quantify the resources external to the hospital (including cost of transportation). The inpatient costs were evaluated using the French diagnosis-related groups. The ambulatory costs were assessed using the French nomenclature. Costs were expressed in 2002 Euro (), according to the French societal perspective. The ICER assessed the cost of one additional life year saved. A discount rate of 5% per year was used for cost, and alternatively 0%, 3% and 5% for effectiveness. We validated the results with a probabilistic sensitivity analysis incorporating parametric and non-parametric bootstraps, and with the acceptability curves., Results: The mean total discounting cost of adjuvant treatments was 11 465 for FEC 50 and 13 815 for FEC 100; the mean total discounting cost of recurrences was 14 636 and 13 503, respectively. According to the discount rate of effectiveness, the life expectancy was 16.5, 11.4 and 9.3 years for FEC 50 and 18.4, 12.5 and 10.2 years for FEC 100. The ICER (cost per life year saved) were 642, 1084 and 1460, respectively. The probability according to which FEC 50 is strictly dominated by FEC 100 was 0.15., Conclusion: The clinical benefit of FEC 100 generates a negligible cost increase when compared with FEC 50.

Objective: The aim of the study was to assess the economic consequences of the early screening and management for overt hypothyrodism in elderly women suffering from hypercholesterolaemia., Methods: A cost analysis was performed using screening decision tree followed by a Markov model, targeted on an hypothetical cohort of elderly women (i.e. > or = 55 years of age) suffering from hypercholesterolaemia. Two arms were compared, "no diagnosis", patients being treated by lipid lowering drugs in the long run, "diagnosis", patients being screened for thyroid disturbance and proposed adequate correction by hormone treatment. Relevant clinical data introduced into the model were obtained from published data and from experts. At the end of the initial diagnostic, patients could enter three different health states: euthyroidism, subclinical hypothyroidism or overt hypothyroidism. During 30 years, patients were assumed to be seen each year by a general practitioner for clinical examination and cholesterol dosage, plus, according to the health state evolution, TSH and T4 screening. In the baseline analysis, euthyroidian patients who had a inexplicable degradation of hypercholesterolaemia control were tested for TSH and, if abnormal, T4 serum; for subclinical hypothyroidian patients, TSH and T4 were measured every year. The direct costs taken into account were concerning medical supervision, drug treatment and biologic exams. Costs were analysed from the societal perspective and were expressed in 1998 French Francs (FF) with an accounting rate of 5% by year. A sensitivity analysis was also performed., Results: The total cost at 30-year was equal to 25,006 F for "diagnosis" strategy, to 24,390 F for "no diagnosis" strategy. The incremental cost of the first strategy decreased according to the time horizon. It was 6.8% at 5-year and 2.5% at 30-year. Results were sensitive to variation in response rate of hypercholesterolaemic patients to hormone treatment of hypothyroidism (0.25 in base-case)., Conclusion: The investment cost in screening and treatment of hypercholesterolemic female patient aged 55 and more can be considered offset in the long run (30 years). Considering the other important outcomes in favour of hormonal drug treatment of hypothyroidism, such as enhancement of well-being, functional capacities and quality of life, the "diagnosis" strategy can be recommended in the ambulatory medical practice.

In the context of a medicoeconomic study of the adjuvant treatment of breast cancer, we evaluated the cost of the recurrence. This cost was assessed from the medical records of 146 patients having presented either distant metastases, or a local recurrence followed or not by metastases between 1983 and 1990. We checked according to published data that the frequency of the metastatic risk is negligible if beyond 5 years after the local recurrence. Costs are expressed in 1995 French Francs (FF), with the French Social Security point of view. From the medical records, we calculated the mean cost of each type of recurrence using medical costs (visits, drugs and treatments, assessments, tests, hospital care, outpatient services.) and non medical costs (patient transportation). The costs are 175,168 FF (standard deviation or SD: 127,972) for metastatic recurrence, and respectively 287,582 FF (SD: 142,280) and 115,705 FF (SD: 78,677) for local recurrence followed or not by metastases. There is a significant difference between these figures (p < 0.001). The hospitalization costs are around 66% of the total cost of each type of recurrences and they are significantly higher (p < 0.005) when metastatic disease occurs after a local recurrence. The mean cost of isolated local recurrence added to metastatic recurrence, 290,873 FF, is not different from that of local recurrence followed by metastases, 287,582 FF (p = 0.15). These results will be integrated in a model in order to evaluate the long-term economic consequences of an adjuvant strategy in the treatment of breast cancer and presented in other publications.

In this study a cost analysis of therapeutics used in the adjuvant treatment of breast cancer has been performed. Four strategies were considered: chemotherapy (FEC, 6 courses), hormone therapy (tamoxifen, 20 mg/day during 3 years), the association of chemotherapy and hormone therapy, or standard follow-up with neither chemotherapy nor hormone therapy. The costs of these strategies were analysed according to the payer's perspective (social security system). In order to complete the economic data, specific investigations were performed at the Centre Oscar-Lambret (COL), a Cancer Center located in Lille (France). The study shows a high cost for chemotherapy (63,767 FF at 5 years) and a high cost for the association (68,891 FF), in comparison to the cost of hormone therapy alone (45,540 FF) or to the follow-up without adjuvant therapy (38,416 FF). These costs could be confronted to the efficacy data of these different strategies and to the cost of avoided relapses. Cost-effectiveness and cost-benefit ratios of these adjuvant strategies could then be assessed.

In recent studies, the economic criteria has begun to be integrated to the appraisal in cancerology. The question asked by the economist can be framed as follows: what incremental cost should the collectivity or the health insurance system consent, in order to improve the care of cancer patients? This involves first that the cost of the strategies, foreseen or already implemented, can be appraised, then, that indicators can be defined to capture health improvement, and finally, that this health improvement can be quantified. In this article, we present the process of integrated appraisal (cost/result approach). We specifically analyze costs in cancerology, their source and their evolution. We demonstrate the meaning of the integration of economic costs and medical results. We emphasize on the fact that part of the costs, especially those supported by the patient and his close relations, are most of the time excluded from the analysis. Two main points should be carefully analyzed, when proceeding to an appraisal in cancerology: the measurement of the patient's QoL, which represents an expression of the results of the strategy of care; the financing modalities, for the same type of care, if we consider the specificity of the structures involved and the organization of the care. We conclude by mentioning how difficult this task is and under which conditions it should be developed.
