Project description:BackgroundThis report describes the clinical work in esophageal cancer radiation group at the Department of Radiotherapy, Tianjin Medical University Cancer Institute & Hospital (TJMUCH).MethodsWe retrospectively analyzed the clinical data of patients with esophageal cancer who received radiotherapy (RT) at TJMUCH during the 5-year period between 2015 and 2019, including RT procedures, RT methods, treatment types, treatment outcomes and complications, and clinical trials.ResultsIn 2015-2019, 1,464 patients with esophageal cancer received RT at the Department of Radiotherapy, TJMUCH. Of these, 1,176 patients received definitive chemoradiotherapy (CRT), 100 received preoperative neoadjuvant CRT, 120 received postoperative adjuvant RT, 49 received post-relapse RT, and 19 received palliative RT for advanced esophageal cancer. Among the patients who received definitive CRT, the incidences of grade 2 and higher radiation esophagitis, radiation pneumonitis, and leukopenia were 19.4%, 3.6%, and 19.7%, respectively; the incidences of grade 3-4 radiation esophagitis, radiation pneumonitis, and leukopenia were 9.4%, 1.2%, and 5.4%, respectively; no grade 5 acute adverse events were observed. Esophageal fistula was the major side effect during the advanced stage of RT. In 2015-2018, 44 patients (5%, 44/846) developed esophageal fistula; of these, 34 cases occurred after RT, and 10 cases occurred during RT. The overall survival was based on the data of 544 patients with esophageal cancer who underwent definitive RT at TJMUCH between March 2010 and September 2016. The median follow-up time was 21.6 months. The median survival was 19.6 months; and the 1-, 3-, and 5-year overall survival rates were 69.4%, 37.2%, and 32.3%, respectively. In 2015-2019, approximately 201 patients participated in different prospective clinical trials.ConclusionsRT is a crucial and effective treatment for esophageal cancer. Standardized treatment procedures, multidisciplinary cooperation, are the foundations for good treatment effects. Many promising ongoing clinical trials will be helpful to improve the prognosis and survival of esophageal cancer patients in the future.

Project description:BackgroundThe current study was undertaken to examine total hospital costs per patient of a consecutive implantation series of two 3rd generation Left Ventricle Assist Devices (LVAD). Further we analyzed if increased clinical experience would reduce total hospital costs and the gap between costs and the diagnosis related grouped (DRG)-reimbursement.MethodCost data of 20 LVAD implantations (VentrAssist™) from 2005-2009 (period 1) were analyzed together with costs from nine patients using another LVAD (HeartWare™) from 2009-June 2011 (period 2). For each patient, total costs were calculated for three phases - the pre-LVAD implantation phase, the LVAD implantation phase and the post LVAD implant phase. Patient specific costs were obtained prospectively from patient records and included personnel resources, medication, blood products, blood chemistry and microbiology, imaging and procedure costs including operating room costs. Overhead costs were registered retrospectively and allocated to the specific patient by predefined allocation keys. Finally, patient specific costs and overhead costs were aggregated into total hospital costs for each patient. All costs were calculated in 2011-prices. We used regression analyses to analyze cost variations over time and between the different devices.ResultsThe average total hospital cost per patient for the pre-LVAD, LVAD and post-LVAD for period 1 was $ 585, 513 (range 132, 640- 1 247, 299), and the corresponding DRG- reimbursement (2009) was $ 143, 192 . The mean LOS was 54 days (range 12- 127). For period 2 the total hospital cost per patient was $ 413, 185 (range 314, 540- 622, 664) and the corresponding DRG- reimbursement (2010) was $ 136, 963. The mean LOS was 49 days (range 31- 93).The estimates from the regression analysis showed that the total hospital costs, excluding device costs, per patient were falling as the number of treated patients increased. The estimate from the trend variable was -14, 096 US$ (CI -3, 842 to -24, 349, p < 0.01).ConclusionThere were significant reductions in total hospital costs per patient as the numbers of patients were increasing. This can possibly be explained by a learning effect including better logistics, selection and management of patients.
