Economic evaluation of chronic lymphocytic leukemia from a hospital management perspective

OBJECTIVES

Treatment of chronic lymphocytic leukemia (CLL) is currently undergoing dramatic changes. We analyzed economic risks in hospitalized patients with CLL from a management perspective.

METHODS

One hundred and twelve patients with CLL hospitalized in 2013 and 2014 at the University Hospital of Cologne were analyzed. To assess profit margins (PMs) per case, diagnosis-related group (DRG) reimbursement data were merged with an internal cost accounting scheme depending on age, prognostic factors, and DRG key performance indicators.

RESULTS

In 112 patients, 284 cases coded by 19 different DRG with strongly fluctuating cost revenue ratios were found with an overall negative PM of €137 147. The DRG R61H was identified as the one most commonly coded (174 cases, 61.3%) with a deficit per case of €814. Subanalysis demonstrated that the payments were not cost covering due to excessive length of stay and staff costs. Significant differences in PM per case concerning age, length of stay and number of operation and procedure key (OPS) codes (P < 0.05) were found.

CONCLUSION

In our research-driven tertiary care hospital, inpatient treatment of patients with CLL is not cost covering. This analysis demonstrates the need for novel care/reimbursement structures in CLL. From a hospital management perspective, cost revenue controlling is crucial to avoid major economic risks.

Outcome of patients experiencing progression or relapse after primary treatment with two cycles of chemotherapy and radiotherapy for early-stage favorable Hodgkin's lymphoma

PURPOSE

To evaluate treatment outcome of patients with early-stage favorable Hodgkin's lymphoma (HL) who experience disease relapse after primary treatment with two cycles of chemotherapy followed by radiotherapy (RT).

PATIENTS AND METHODS

Of 1,129 patients with early-stage favorable HL enrolled onto the HD7/HD10/HD13 trials of the German Hodgkin Study Group, 42 patients were identified with treatment failure, of whom eight had primary progressive disease, seven had early relapse (< or = 12 months), and 27 had late relapse (> 12 months). We analyzed this group of patients for risk factors, salvage therapy, and treatment outcome.

RESULTS

The median age was 41 years (range, 19 to 72 years); 24 patients were male, 15 patients had outfield relapse, 13 patients infield relapse, and nine patients outfield and infield relapse. At relapse, 24 patients were treated with conventional salvage chemotherapy, 14 patients were treated with high-dose chemotherapy followed by autologous stem-cell transplantation, and four patients were treated with RT alone. At 36 months median follow-up, freedom from second treatment failure (FF2F) and overall survival (OS) were 52% and 67%, respectively. According to the prognostic score for relapsed HL (duration of first remission, clinical stage, and anemia at relapse), patients with two or three poor prognostic features had a significantly worse outcome compared with patients with none or one of these factors (P < .05 for FF2F and OS).

CONCLUSION

Relapse after primary treatment with two cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine followed by RT is rare. In our analysis, results were influenced by a high treatment-related mortality rate. Additional studies are needed to define the optimal salvage therapy.

Rituximab added to an intensified salvage chemotherapy program followed by autologous stem cell transplantation improved the outcome in relapsed and refractory aggressive non-Hodgkin lymphoma

We investigated the addition of rituximab to an intensified salvage program followed by a myeloablative course with autologous stem cell transplantation (ASCT) in patients with relapsed or refractory aggressive non-Hodgkin lymphoma (NHL). Patients with relapsed or progressive aggressive NHL were treated with two cycles of conventional salvage chemotherapy (DHAP) followed by high-dose sequential chemotherapy (cyclophosphamide, methotrexate with vincristine and etoposide) and a final myeloablative course (BEAM) with ASCT. Rituximab (375 mg/m(2)) was administered at each treatment cycle. This cohort was compared with a historical control group of patients treated with the same chemotherapy but without rituximab. Patients from both groups were matched by duration of first remission and lactate dehydrogenase serum levels. Forty-five patients were treated with chemotherapy and 22 with immunochemotherapy. The overall response rates (ORR) at the final evaluation were 63% for the immunochemotherapy group and 42% for the chemotherapy group (p = 0.330). In the historical controlled analysis freedom from second failure (FF2F) at 2 years in the immunochemotherapy group was 57% and overall survival (OS) was 77%. FF2F in the chemotherapy group was 18% (p = 0.0051) and OS was 37% (p = 0.0051). In the matched-pair analysis, FF2F was 58% in the immunochemotherapy group compared to 16% in the chemotherapy group (p = 0.0517); OS was 74 vs 33%, respectively (p = 0.0424). The toxicity was tolerable and comparable in both groups. The addition of rituximab to an intensified salvage chemotherapy regimen seems to improve the prognosis. However, only prospective randomized trial can offer sufficient data of the value of rituximab in relapsed and refractory aggressive NHL.

Autologous tandem transplantation in patients with primary progressive or relapsed/refractory lymphoma

Patients with primary progressive or refractory Hodgkin's disease (HD) or aggressive non-Hodgkin's lymphoma (NHL) have a particularly poor prognosis. Here we report the results of autologous tandem transplantation in these patients. Patients aged 18-55 years with primary progressive or refractory relapsed HD and aggressive NHL were included. Patients received high-dose etoposide (2000 mg/m(2)) followed by peripheral blood stem cell harvest (PBSC). The first high-dose chemotherapy (TMC) consisted of thiotepa (750 mg/m(2)), mitoxantrone (40 mg/m(2)), and carboplatin (990 mg/m(2)). Patients with no change (NC), partial remission (PR), or complete remission (CR) after TMC then received BEAM with carmustine (300 mg/m(2)), etoposide (1200 mg/m(2)), cytarabine (1600 mg/m(2)), and melphalan (140 mg/m(2)). Patients with bulky disease (>5 cm) or residual lymphoma received involved field radiotherapy. Twenty-five patients were included (HD=10, NHL=15, median age 34 years). Two patients with HD achieved a CR and five patients a PR [response rate (RR) 70%]. Three patients (30%) experienced treatment failure including two deaths due to peritransplant complications. Five patients with aggressive NHL were in CR and two patients in PR (RR 46%). Of the eight patients (56%) with treatment failure, three had progressive disease and five died from peritransplant complications. Freedom from treatment failure (FFTF) and overall survival (OS) for all patients after 12 months was 28% and 40%, respectively. Tandem HDCT followed by autologous stem cell transplantation (ASCT) offers a chance of cure in these poor prognostic patients, but is associated with risks.

Salvage Radiotherapy in Patients With Relapsed and Refractory Hodgkin’s Lymphoma: A Retrospective Analysis From the German Hodgkin Lymphoma Study Group

Purpose

To evaluate treatment outcome and prognostic factors in patients with refractory or first relapsed Hodgkin’s disease (HD) treated with salvage radiotherapy (SRT) alone.

Patients and Methods

From 4,754 patients registered in the database of the German Hodgkin Study Group from 1988 to 1999, 624 patients were identified with progressive disease (n = 202), or with early (n = 170) or late (n = 252) relapsed HD. At first treatment failure, SRT alone was given to 100 patients. Patient characteristics were: median age, 36 years; progressive disease, 47%; early relapse, 23%; late relapse, 30%; and “B” symptoms, 14%. Eighty-five percent of the patients relapsed after cyclophosphamide, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (COPP/ABVD) –like regimens; 8% after bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) regimens, 7% after first-line radiotherapy alone.

Results

The volume irradiated was mantle field in 43% of patients, inverted-Y in 8%, total nodal irradiation in 12%, and involved-field in 37%. The median SRT dose was 40 Gy (range, 15 to 50 Gy). Seventy-seven patients achieved a complete remission and four patients achieved a partial remission. The 5-year freedom from treatment failure and overall survival (OS) rates were 28% and 51%, respectively. In multivariate analysis, significant prognostic factors for OS were B symptoms (P = .018) and stage at relapse (P = .014). For freedom from second failure (FF2F) Karnofsky performance status (P = .0001) was significant. In patients with limited stage at progression/relapse, duration of first remission was significant (P = .04) for FF2F.

Conclusion

SRT offers an effective treatment for selected subsets of patients with relapsed or refractory HD.

Extramedullary acute myeloid leukemia (granulocytic sarcoma) with arm paresis, maculopapular exanthema and organ involvement

Granulocytic sarcoma (extramedullary myelosarcoma, chloroma) is a rare extramedullary myeloid tumor which can occur at any anatomical site as isolated finding or associated with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). In this case, we describe a 71-year-old man who presented with incomplete paresis of the left arm, periorbital swelling, a maculopapular exanthema and organ involvement including testis and stomach. The tumors responded to combination chemotherapy and the patient fully recovered. However, after five months the patient relapsed and died quickly. This case confirms the importance of including granulocytic sarcoma in the differential diagnoses of a variety of diseases. In AML, the presence of granulocytic sarcoma is associated with worse overall survival. When diagnosed, it should be treated with intensive chemotherapy as soon as possible.

[Hepatitis-C-virus-associated cryoglobulinemia. Pathogenesis, diagnosis and treatment]

BACKGROUND

Chronic hepatitis C-virus (HCV) infection is frequently associated with a variety of autoimmune phenomenons. Mixed cryoglobulins appear in up to 50% of chronic HCV-infected patients, mostly asymptomatic.

PATHOGENESIS

Cryoprecipitates present IgM with rheumatoid factor activity and development of immunocomplexes deposited in small vessels responsible for resulting vasculitis. MANIFESTATIONS: Characteristic clinical findings are weakness, arthralgia and purpura with further complications including glomerulonephritis and neuropathic lesions. Several mechanisms for HCV-induced clinical lymphoproliferation are discussed, such as chronic B-cell stimulation and activation of the antiapoptotic oncogene bcl-2 leading to immunoglobulin synthesis and eventually evolving into B-cell non-Hodgkin's lymphoma (NHL).

TREATMENT

Conventional treatment of HCV-associated mixed cryoglobulinemia aimes at reducing circulating immunocomplexes and causal therapy with interferon (IFN) and ribavirin. New approaches using the anti-CD20 antibody rituximab have been described recently.

New treatments for Hodgkin's disease

Four of five patients with Hodgkin's disease (HD) will be cured with modern treatment strategies, depending on stage and risk factor profile. In early stage favorable HD, cure rates are greater than 90% with extended field (EF) irradiation, the standard treatment. However, the concept of EF irradiation therapy is being abandoned by most study groups because of the recognition of fatal long-term effects, especially the high rates of second solid tumors. Newer approaches include mild chemotherapy combined with involved field (IF) irradiation to control occult disease. Combined modality is the treatment of choice in early stages unfavorable (intermediate) HD, in which EF irradiation is substituted by IF irradiation. In the last three decades, because of the high relapse rates (30%-50%) after first-line polychemotherapy, the standard regimens were often modified. However, until recently, these efforts could not change the relatively poor outcome for patients with advanced stage disease. The introduction of a new dose-intensified regimen (BEACOPP) has significantly improved the prognosis for patients with advanced HD. Patients who relapse after radiation therapy alone for early stage HD have satisfactory results with combination chemotherapy and are not considered as candidates for high-dose chemotherapy with autologous stem cell transplantation. For patients with relapsed HD after combination chemotherapy, the data support the use of high-dose chemotherapy with autologous stem cell transplantation.

Can factors influencing in-patient treatment in Hodgkin's disease be identified?--Retrospective analysis of HD6 patients of the GHSG

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.

["Lean management" in hospitals: potentials and limitations]

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.
