RESUMO

OBJECTIVES: The recent success of individualized lung cancer therapy has triggered fundamental changes in clinical research strategies. To date there is a strong focus on early proof of concept trials in genetically preselected small patient subgroups. This analysis focuses on the economic burden caused by such trials for advanced lung cancer patients in a German Comprehensive Cancer Center (CCC). METHODS: The profit margins between recruiting groups with ≤3 and >3 patients were compared. Clinical and economic data from clinical trials for advanced lung cancer (LC), pharma-sponsored trials (PhST) as well as investigator initiated trials (IIT), conducted between 2011 and 2015 at the Center for Integrated Oncology (CIO) Cologne, were analyzed using a profit-center calculation model. RESULTS: 161 patients were enrolled in 27 clinical trials. The key economic parameter determining costs and payments was the 'trial visits'. In comparison of the two groups (A≤3; B>3 patients enrolled) we found negative profit margins for the low recruiting group (€ -1444). Concerning the number of visits significant differences were found between PhST and IIT (p=0.009). Additionally, sub-analysis show structural differences in cost composition by conducting PhST and IIT. CONCLUSION: Trials with low patient numbers and IIT, do not cover the cost. To ensure adequate, cost-covering compensation by pharmaceutical companies CCCs have to thoroughly calculate the cost of early proof of concept trials. The findings of this study also underline the need for novel structures in public funding for investigator-initiated clinical trials in precision medicine.

RESUMO

BACKGROUND: Combination chemotherapy can cure patients with non-Hodgkin's lymphoma (NHL), but those who suffer treatment failure or relapse still have a poor prognosis. High-dose chemotherapy (HDCT) with autologous stem cell transplantation (ASCT) can improve the outcome of these patients. We evaluated an intensified high-dose sequential chemotherapy program with a final myeloablative course. PATIENTS AND METHODS: Inclusion criteria were age 18-65 years, histologically proven primary progressive or relapsed aggressive NHL and eligibility for HDCT. The therapy consists of two cycles DHAP: dexamethasone 40 mg (day 1-4), high-dose cytarabine 2 g/m2 12q (day 2), cisplatin 100 mg/m2 (day 51); patients with partial (PR) or complete remission (CR) received cyclophosphamide 4 g/m2 (day 37), followed by peripheral blood stem cell (PBSC) harvest; methotrexate 8 g/m2 (day 1) plus vincristine 1.4 mg/m2 (day 51); and etoposide 500 mg/m2 (day 58-62). The final myeloblative course was BEAM: cytarabine 200 mg/m2 12q (day 81-84), etoposide 150 mg/m2 12q (day 81-84), melphalan 140 mg/m2 (day 80), carmustin 300 mg/m2 (day 80) followed by PBSCT. RESULTS: Fifty-seven patients (median age 43 years, range 24-65) were enrolled: 23 (40%) patients were refractory to primary therapy and 34 (60%) patients had relapsed NHL. The response rate (RR) after 2 cycles of DHAP was 72% (9% CR, 63% PR) and at the final evaluation (100 days post transplantation) 43% (32% CR, 11% PR). Toxicity was tolerable. Median follow-up was 25 months (range 1-76 months). Freedom from second failure (FF2F) and overall survival (OS) at 2 years were 25% and 47% for all patients, respectively. FF2F at 2 years for patients with relapse and for patients refractory to primary therapy were 35% and 9% (P=0.0006), respectively. OS at 2 years for patients with relapse and for patients refractory to primary therapy were 58% and 24% (P=0.0044), respectively. CONCLUSIONS: We conclude that this regimen is feasible, tolerable and effective in patients with relapsed NHL. In contrast, the results in patients with progressive disease are unsatisfactory. This program is currently being modified by addition of rituximab for patients with relapsed aggressive NHL.

RESUMO

BACKGROUND: We designed a dose- and time-intensified high-dose sequential chemotherapy regimen for patients with relapsed and refractory Hodgkin lymphoma (HD). PATIENTS AND METHODS: Eligibility criteria included age 18-65 years, histologically proven primary progressive (PD) or relapsed HD. Treatment consisted of two cycles DHAP (dexamethasone, high-dose cytarabine, cisplatinum); patients with chemosensitive disease received cyclophosphamide followed by peripheral blood stem cell harvest; methotrexate plus vincristine, etoposide and BEAM plus peripheral blood stem cell transplantation (PBSCT). RESULTS: A total of 102 patients (median age 34 years, range 18-64) were enrolled. The response rate was 80% (72% complete response, 8% partial response). With a median follow-up of 30 months (range 3-61 months), freedom from second failure (FF2F) and overall survival (OS) were 59% and 78% for all patients, respectively. FF2F and OS for patients with early relapse were 62% and 81%, for late relapse 65% and 81%; for PD 41% and 48%, and for multiple relapse 39% and 48%, respectively. In multivariate analysis response after DHAP (P <0.0001) and duration of first remission (PD and multiple relapse versus early and late relapse; P=0.0127) were prognostic factors for FF2F. Response after DHAP (P <0.0081), duration of first remission (P=0.0017) and anemia (P=0.019) were significant for OS. CONCLUSION: Based on the promising results of this study, a prospective randomized European intergroup study was started comparing this intensified regimen with two courses of DHAP followed by BEAM (HD-R2 protocol).

RESUMO

The aim of the study was to investigate the effects of erythropoietin (epoetin beta) on red blood cell (RBC) transfusions, hemoglobin (Hb) levels, and quality of life (QOL) in patients with relapsed lymphoma treated with an aggressive sequential salvage chemotherapy (SSCT) regimen. Sixty patients with early or late relapsed Hodgkin's disease ( n=39) or first relapse of aggressive non-Hodgkin's lymphoma ( n=21) were randomized to receive epoetin beta 10,000 IE subcutaneously three times a week or no epoetin during salvage chemotherapy. Patients in both study arms received two cycles of DHAP (dexamethasone, high-dose cytarabine, cisplatin); patients in partial remission (PR) or complete remission (CR) then received cyclophosphamide, followed by peripheral blood stem cell (PBSC) harvest, methotrexate plus vincristine, and etoposide. The final myeloablative course was BEAM (carmustine, etoposide, cytarabine, and melphalan) followed by autologous stem cell support. The primary endpoint of the study was the number of RBC units needed during SSCT. In addition, Hb levels and QOL were measured. The mean number of RBC units given in the epoetin beta arm was 4.5 compared to 8.3 in the control arm ( P=0.0134). The mean Hb levels during therapy were 10.4 g/dl in the epoetin beta arm and 9.7 g/dl in the control ( P=0.018). From baseline until BEAM therapy QOL (EORTC QLQ C30) and fatigue (MFI) assessment showed little QOL worsening or stable levels in both arms with a steeper increase of fatigue levels in the control group. Patients with relapsed lymphoma undergoing aggressive chemotherapy and stem cell support benefited from epoetin beta therapy, with a decrease of RBC transfusion requirements and lower rise of fatigue levels.

RESUMO

Little attention has yet been payed on establishing modern and competitive organizational structures in German hospitals. In this paper, we attempt to apply elements of lean management to the work of physicians working in an inpatient setting. Traditional ways of communication and their disadvantages are discussed. These include loss of motivation, bureaucratic structures and a lack of interdisciplinary cooperation. Using Maslow's theory of motivation, possible improvements are discussed, such as the reduction of restrictive job characteristics, an increase of physicians' spheres of competence and the use of their innovative potentials. These suggestions are explained using practical examples. The aim of the study is to contribute to quality management in hospitals by increasing personal responsibilities according to lean management.

RESUMO

Patients receiving chemotherapy for Hodgkin's disease can potentially be treated in the out-patient department. In spite of this the proportion of patients receiving the chemotherapy on in-patient departments is 54% per chemotherapy cycle in average in the HD6 trial for advanced Hodgkin's disease of the German Hodgkin Study Group (GHSG). The aim of this retrospective analysis is to identify the set of parameters which influence the decision of in- or out-patient treatment for the patients in the HD6 trial. Parameters tested in the univariate analysis are the patient characteristics, the type of chemotherapy, toxicity and the type of treatment institution. The significant parameters are included in a logistic regression model. From this multivariate analysis the type of treatment institution turned out to be the most important factor in the decision of treatment setting. Restricting the analysis to university clinics, the treatment setting of the first two cycles is more influencial than patient dependent parameters.
