Subsequent primary neoplasms after childhood cancer therapy - design and description of the German nested case-control study STATT-SCAR.

BACKGROUND: Subsequent primary neoplasms (SPN) are among the most severe late effects and the second most frequent cause of death in childhood cancer patients. In this paper we introduce method and properties of the STATT-SCAR study (Second Tumor After Tumor Therapy, Second Cancer After Radiotherapy), which is a joint nested matched case-control study to evaluate the impact of chemotherapy (STATT) as well as radiotherapy (SCAR) on the risk of developing a SPN. METHODS: Based on the cohort of the German childhood cancer registry (GCCR), we selected patients diagnosed with a first neoplasm before age 15 or younger between 1980 and 2014. We selected those with a SPN at least half a year after the first neoplasm, and matched up to four controls to each case. Therapy data were acquired from various sources, including clinical study centers and treating hospitals. To analyze the impact of radiotherapy, organ doses were estimated by using reconstructed treatment plans. The effect of chemotherapy was analyzed using substance groups summarized after isotoxic dose conversion. RESULTS: 1244 cases with a SPN were identified and matched with 4976 controls. Treatment data were acquired for 83% of all match groups (one case and at least one control). Based on preliminary analyses, 98% of all patients received chemotherapy and 54% of all patients were treated with radiotherapy. CONCLUSIONS: Based on our data, detailed analyses of dose response relationships and treatment element combinations are possible, leading to a deeper insight into SPN risks after cancer treatments. TRIAL REGISTRATION: The study is registered at the German clinical trial register (DRKS) under number DRKS00017847 [45].

Equivalent doses for anticancer agents used in pediatric oncology: A literature review and evaluation of a novel approach for conversion factors.

BACKGROUND: Epidemiological research on late effects of therapy shows the necessity to aggregate chemotherapy agents to substance classes. This requires using conversion factors by substance classes. AIMS: The aim of this study was to identify previously used conversion factors from the literature, to present a novel approach for additional factors, and to compare these approaches. METHODS AND RESULTS: A literature review was performed, which identified two main principles of deriving conversion factors: effect-equivalence and equimolar. Thirty-five articles presenting effect equivalence-based factors in the widest sense were found in the literature. Ten articles presented the equimolar approach which can be applied to almost all chemotherapy substances. Based on a comprehensive list of treatment protocols used in German pediatric oncology, we derived alternative conversion factors from typical doses. We compared the conversion factors using Pearson correlation coefficients and linear regression. At least two types of conversion factor were available for each of the 49 substances included. The equivalent effect-based and the typical dose-based factors were highly correlated with a regression coefficient close to 1. The equimolar factors are independent. CONCLUSIONS: For substances for which no conversion factor based on some type of effect equivalence has been published so far, a factor based on a typical doses-approach may be used in epidemiological late effects research. Doses aggregated based on the equimolar approach may not be compatible with doses aggregated based on equivalent effects.

Impact of the changing landscape of induction therapy prior to autologous stem cell transplantation in 540 newly diagnosed myeloma patients: a retrospective real-world study.

INTRODUCTION: Autologous stem cell transplantation (ASCT) is the standard treatment for younger patients with newly diagnosed multiple myeloma (MM). However, due to restrictive exclusion criteria, more than half of eligible patients are usually excluded from transplant studies. METHODS: This retrospective monocentric analysis included 540 patients with MM who received an ASCT between 1996 and 2019. RESULTS: Up to 2005, induction therapy consisted mainly of conventional chemotherapies, e.g. vincristine/doxorubicin/dexamethasone (VAD). In the following years, the triple-combinations based on bortezomib coupled with doxorubicin/dexamethasone (PAD), melphalan/prednisolone (VMP), cyclophposphamide/dexamethasone (VCD) or bendamustine/prednisolone (BPV) became the most popular treatment options. A progressive improvement in PFS was observed in patients treated with the two current induction therapies BPV (47 months) or VCD (54 months) compared to VAD (35 months, p < 0.03), PAD (39 months, p < 0.01 and VMP (36 months, p < 0.01). However, there was no significant difference in median OS (VAD 78, PAD 74, VMP 72, BPV 80 months and VCD not reached). In our analysis, we also included 139 patients who do fulfill at least one of the exclusion criteria for most phase 3 transplant studies (POEMS/amyloidosis/plasma cell leukemia, eGFR < 40 mL/min, severe cardiac dysfunction or poor general condition). Outcome for these patients was not significantly inferior compared to patients who met the inclusion criteria for most of the transplant studies with PFS of 36 vs 41 months (p = 0.78) and OS of 78 vs 79 months (p = 0.34). CONCLUSIONS: Our real-world data in unselected pts also stress the substantial value of ASCT during the first-line treatment of younger MM pts.

Two rare cases of bronchus-associated lymphoid tissue lymphoma successfully treated with rituximab-bendamustine.

BALT lymphoma is a rare B-NHL with a favorable prognosis. We here report on two patients with nonspecific symptoms: one showed as major symptom severe thrombocytopenia and the other dyspnea and dry cough, thereby suggesting an inflammatory focus in the lungs. There is no standard of care established yet. Both patients were successfully treated with rituximab and bendamustine. Thus, combined immunochemotherapy should be considered as first-line therapy as in other MALT lymphomas, if the treatment/eradication of an underlying chronic inflammatory disorder/trigger factor can be excluded.

Prognostic impact of rapid reduction of involved free light chains in multiple myeloma patients under first-line treatment with Bendamustine, Prednisone, and Bortezomib (BPV).

INTRODUCTION: Light chain involvement is observed in almost every patient (pt) with newly diagnosed multiple myeloma (MM). Owing to a relatively short half-life, rapid reduction in the involved free light chain (iFLC) is of potential prognostic value. METHODS: This retrospective analysis included 92 pts with newly diagnosed MM treated with bendamustine, prednisone, and bortezomib (BPV). RESULTS: After a median number of two (range 1-5) BPV cycles, the majority of pts (n = 86; 93%) responded with either sCR (n = 21), CR (n = 1), nCR (n = 25), VGPR (n = 20), or PR (n = 19). PFS and OS at 48 months were 39% and 67%, respectively. At baseline, 79 out of 92 pts (86%) had iFLC levels above the upper standard level and an abnormal ratio of involved to uninvolved free light chain ≥ 8. In a subgroup analysis of these pts, we evaluated the prognostic importance of an early reduction of the iFLC during the first two BPV cycles. A reduction ≥ 50% of the iFLC on day 8 of the first cycle was observed in 31 of 69 pts. These pts had a significantly better median PFS of 49 months as compared to 20 months in 38 pts with a lower iFLC reduction (p = 0.002). In contrast, OS did not differ significantly with a 48 months survival of 77% vs 69% (p > 0.05). CONCLUSION: These results indicate that a rapid decrease in the iFLC on day 8 is an early prognostic marker for newly diagnosed MM pts undergoing BPV treatment.

Patterns of Prior and Subsequent Neoplasms in Children and Adolescents With Soft Tissue Sarcomas.

BACKGROUND: The occurrence of prior, concurrent and subsequent neoplasms (SN) represents a serious problem in children and adolescents with soft tissue sarcomas. Pathogenic germline variants contribute to the diagnosis of multiple neoplasms in sarcoma survivors. MATERIALS AND METHODS: The records of 748 children and adolescents, diagnosed with soft tissue sarcomas and registered in trials/registries by the cooperative soft tissue sarcoma (Cooperative Weichteilsarkom Studie) group, were reviewed for the occurrence of SNs. Reference histology review was available for all cases; the presence of oncogenic fusions known at the time of diagnosis was confirmed for fusion-positive (F+) entities. RESULTS: Concurrent or subsequent SNs developed in 13 of 473 survivors of fusion-negative (F-) sarcomas, for an 8-year cumulative SN incidence of 5% in survivors of F- sarcomas. In contrast, only 1 of 278 survivors of F+ sarcoma developed an SN. Twenty of 748 patients with soft tissue sarcomas had a history of prior neoplasms. Six of 14 patients who developed SNs after their index sarcomas met Chompret criteria for Li-Fraumeni syndrome. Nine of 20 patients who had tumors before their index sarcoma diagnosis had neurofibromatosis type 1 or neurofibromatosis type 1 spectrum tumors. CONCLUSION: Sarcoma phenotype/genotype and the sequence and nature of prior and subsequent neoplasms provide a window into underlying germline genetic susceptibilities in children and adolescents with soft tissue sarcomas.

Early deaths from childhood cancer in Germany 1980-2016.

BACKGROUND: Even though the survival of childhood cancer has improved over the last decades, there are still children dying shortly after diagnosis. The aim of the study is to add to understanding of the reasons for deaths shortly after date of diagnosis. METHODS: Using data of the population-based German Childhood Cancer Registry (cancer below 15 years of age diagnosed between 1980 and 2016), we compared characteristics of 671 children with cancer who died within 30 days of diagnosis to 53,649 patients with childhood cancer who survived longer. In addition to a descriptive analysis, we used logistic regression with multivariable fractional polynomials to describe the relationship between early death with age at diagnosis and year of diagnosis. RESULTS: The number of early death cases and the risk of early death have decreased considerably since 1980 (2.6% of study population in 1980-89 to 0.6% in 2010-16). Children under one year of age were at highest early death risk (odds ratio = 4.10, 95% confidence interval: 3.32-5.05 compared to 7-year-old patients). These results are similar to results from other studies. Moreover, children with acute myeloid leukemia and hepatic tumors had a higher early death risk, children with acute lymphoid leukemia a lower risk compared to patients with central nervous system tumors used as a reference group. CONCLUSION: Even though the risk for early death has declined overall with advances in diagnosis and therapy, special attention needs to be paid to infants and children with AML and hepatic tumors, who are especially at risk.

Quality improvement in maternal and newborn healthcare: lessons from programmes supported by the German development organisation in Africa and Asia.

Improving the quality of maternal and child healthcare (MCH) is a mandatory step on the path to reaching the Sustainable Development Goals and Universal Health Coverage. Quality improvement (QI) in MCH is a strong focus of the bilateral development cooperation provided by Germany to help strengthen the health systems of countries with high maternal and child mortality rates and/or with high unmet needs for family planning. In this article, we report on the findings of an analysis commissioned by a community of practice on MCH, of Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ). The objectives were to review the QI interventions implemented through programmes which have received technical assistance from GIZ on behalf of the German Federal Ministry for Economic Cooperation and Development in 14 Asian and African countries, to identify and describe the existing approaches and their results, and finally to draw lessons learnt from their implementation. Our analysis of the information contained in programme documents and reports identified five main methodologies used to improve the quality of care: capacity-building and supervision, governance and regulation, systemic QI at facility level, support to infrastructures, and community support. It is difficult to attribute the observed progresses in maternal and neonatal health to a particular agency, programme or intervention. We acknowledge that systemic implementation research embedded within the programmes would facilitate an understanding of the determinants of successful QI interventions, would better assess their effectiveness, and therefore better guide future bilateral aid programmatic decisions.

Second Malignancies Following Childhood Cancer Treatment in Germany From 1980 to 2014.

BACKGROUND: Because of improvements in cancer treatment, more than 80% of all children with cancer now survive at least five years from the time of diagnosis. As a result, late sequelae of cancer and its treatment have become more common, particularly second malignancies. We studied the current incidence of second malignancies among childhood cancer survivors in Germany. METHODS: This study is based on the cohort of the German Childhood Cancer Registry (Deutsches Kinderkrebsregister, DKKR). Persons given the diagnosis of a first malignancy at any time in the years 1980-2014 who were no more than 14 years old at the time of diagnosis and survived at least six months thereafter were included in the study. Cumulative incidences and hazard ratios were calculated, and comparisons with the general population were made with the aid of standardized incidence ratios (SIR). RESULTS: Among the 47 650 survivors included in the study, there were 1262 cases of second malignancies. After a follow-up interval of up to 35 years, the cumulative incidence of second malignancies was 8.27% (95% confidence interval [7.51; 9.03]). Second malignancies were more common in female patients (hazard ratio 1.29, [1.16; 1.44]) and in those who had had a systemic cancer as their initial malignancy (hazard ratio 1.22 [1.09; 1.36]). The SIR compared to the general population for the period 1955-2014 was 7.08 [6.42; 7.9] for female patients and 5.83 [5.27; 6.42] for male patients. CONCLUSION: The cumulative incidence of second malignancies is 5.4% at 25 years and 8.3% at 35 years; these figures may be slight underestimates. The DKKR is an epidemiologic registry containing no data about treatment, so the effect of treatment on the risk of second malignancies could not be studied. The acquisition and evaluation of treatment data for the overall cohort is currently one of the main tasks for research on the late sequelae of childhood cancer. This may enable conclusions to be drawn about whether treatment strategies that have been introduced to lessen the risk of a second malignancy actually have the desired effect.

"We do not dare to love": women with disabilities' sexual and reproductive health and rights in rural Cambodia.

There is an urgent need for an evidence base to inform the implementation of disability inclusive sexual and reproductive health (SRH) policy and programming to address women with disabilities' largely unattained SRH rights. This paper presents findings from a qualitative study on the sexual and reproductive health and rights (SRHR) of women with disabilities in rural Cambodia. The findings highlight three critical steps to enhance the physical, communicative and financial accessibility of SRHR information and services. Firstly, strengthen women with disabilities' economic livelihoods, social and financial resources, and thereby, their capacity to make and act on their own SRHR decisions. Secondly, engage women with disabilities as community role models and advocates who actively provide input into health service decision-making, planning and delivery. Thirdly, ensure health centre staff have access to communication resources and aids to strengthen their skills to communicate with women with hearing impairments. Together these steps will support women with disabilities to claim their sexual and reproductive rights and transform the social attitudes of persons in the lives of women with disabilities, including health care staff.

Lenalidomide in combination with bendamustine and prednisolone in relapsed/refractory multiple myeloma: results of a phase 2 clinical trial (OSHO-#077).

INTRODUCTION: While lenalidomide monotherapy is established for relapsed and/or refractory multiple myeloma (MM) treatment, combination therapies including lenalidomide are still under investigation in a number of phase 2/3 studies. In the current study, a treatment regime of lenalidomide (Revlimid®), bendamustine and prednisolone (RBP) was tested in patients with relapsed/refractory MM. METHODS: In the previously completed phase 1 study RBP with a dose of 75 mg/m2 bendamustine days 1-2, prednisolone 100 mg days 1-4 and 25 mg lenalidomide days 1-21 was well tolerated. RESULTS: Between July 2011 and September 2013, 25 patients were included in this analysis. The median number of previous treatments was 1 (range 1-2). Twenty-two patients (88%) responded after at least two cycles of RBP (one sCR, five nCR, eight VGPR and eight PR). The median time to first haematological response was 28 days, and median time to best response was 56 days. Due to increased haematological toxicity a dose reduction in most patients required in subsequent cycles of therapy. The median progression-free and overall survival was 22 and 38 months, respectively. In conclusion RBP is a highly effective therapy for patients with relapsed/refractory MM. In contrast to our phase 1 study, dose reduction was necessary in many patients because of haematological toxicity.

Successful treatment of patients with newly diagnosed/untreated light chain multiple myeloma with a combination of bendamustine, prednisone and bortezomib (BPV).

INTRODUCTION: Patients with light chain myeloma frequently have a light chain tubular cast nephropathy, which can lead to severe renal impairment. In the present retrospective study, bortezomib was combined with other active substances like bendamustine and prednisone (BPV), in order to assess the efficacy and toxicity of the combination therapy in patients with light chain multiple myeloma. METHODS: Between September 2008 and May 2015, 25 patients with newly diagnosed light chain multiple myeloma were treated with bendamustine 60 mg/m2 on days 1 and 2, bortezomib 1.3 mg/m2 on days 1, 4, 8 and 11, and prednisone 100 mg on days 1, 2, 4, 8 and 11 once every 21 days (BPV). Prior to treatment, 4 patients (16%) had moderate renal dysfunction and 14 patients (56%) severe renal dysfunction or renal failure/dialysis. RESULTS: The median number of the BPV cycles was 2 (1-5). 24 patients (96%) responded with 4 stringent complete responses, 6 near-complete responses, 5 very good partial responses and 9 partial responses. The myeloma light chains decreased rapidly, reaching the best response after the first cycle in 9 and after the second cycle in additional 12 patients. 17 patients discontinued therapy after median 2 cycles of BPV treatment to receive autologous or allogeneic SCT. All together 12 of 18 patients with at least moderate renal failure improved their renal function. 3 of the 6 dialysis-dependent patients became dialysis-independent. With a median follow-up of 27 months, median progression-free survival and overall survival for patients at 30 months were 68 and 96%, respectively. The most common severe side effect was grade 3/4 leukocytopenia in 20% of the patients. Grade 3/4 thrombocytopenia was observed in 12% of the patients. Moderate to severe infection were seen in six patients. We conclude that BPV is effective and well tolerated in patients with newly diagnosed/untreated light chain multiple myeloma.

Pediatric bone tumors in Germany from 1987 to 2011: incidence rates, time trends and survival.

BACKGROUND: Malignant bone tumors are a rare group of childhood cancer. MATERIALS AND METHODS: This study describes incidence rates, survival probabilities, and time trends for 1831 children below 15 years of age with a bone tumor registered at the population-based German Childhood Cancer Registry between 1987 and 2011. RESULTS: Overall age-standardized annual incidence rate (ASR) was 5.5 per million. Osteosarcomas (ASR 2.8) and Ewing tumors (ASR 2.6) were the most frequent diagnostic groups. The incidence of bone tumors overall tended to increase slightly over time by 0.7% each year on average. Thirty-nine of the bone tumor cases reported were subsequent primaries and not included into the survival analysis. Survival probabilities remained largely constant. DISCUSSION: Possibly survival was largely constant because chemotherapy has not changed much over time. Overall, the results are similar to other results reported from Europe.

Stem cell mobilization and autologous stem cell transplantation after pretreatment with bendamustine, prednisone and bortezomib (BPV) in newly diagnosed multiple myeloma.

INTRODUCTION: Reliable information on stem cell toxicity and mobilization of stem cells for autologous stem cell transplantation (SCT) after induction treatment with a combination of bendamustine, prednisone and bortezomib (BPV) is missing. MATERIALS AND METHODS: A retrospective analysis of peripheral blood stem cell mobilization and autologous SCT was performed in 35 patients with MM who had received at least one cycle of a BPV-induction therapy consisting of bendamustine 60 mg/m(2) on days 1 and 2, bortezomib 1.3 mg/m(2) on days 1, 4, 8 and 11 and prednisone 100 mg on days 1, 2, 4, 8 and 11 between October 2008 and May 2014. The mobilization regimen consisted of cyclophosphamide 4 g/m(2) and G-CSF (2 × 5 µg/kg). Apheresis was started as soon as peripheral CD34(+) counts exceeded 20 × 10(6)/L with a harvest target of 8 × 10(6) CD34(+)/kg. The minimal accepted target was 2 × 10(6) CD34(+)/kg. The transplantation conditioning therapy consisted of melphalan 200 mg/m(2). RESULTS: A median number of two (range 1-5) BPV cycles were given. The majority of patients (n = 31, 89 %) responded with two sCR, five nCR, 11 VGPR and 13 PR after BPV induction. Three patients had MR, and one SD. Stem cell mobilization and harvest were successful in all patients. In 19 of 35 patients (54 %), a single apheresis was sufficient to reach the target. The median number of aphereses was one (range 1-4), and the median CD34(+) cell-count/kg was 13.5 (range 3.2-33.1)  × 106. All patients received an autologous SCT. Engraftment was successful in 34 of 35 patients. The median time to a leukocyte count >l × 10(9)/L was 11 days, and the time to untransfused platelet count of >50 × 10(9)/L was 13 days. Thirty-four patients (97 %) responded after the autologous SCT with 11 sCR, two CR, seven nCR, seven VGPR and seven PR. The progression-free survival at 18 months was 87 %, and overall survival was 92 %. CONCLUSION: Stem cell mobilization and autologous SCT are feasible in MM patients who have received BPV-induction therapy .

Bendamustine and prednisone in combination with bortezomib (BPV) in the treatment of patients with newly diagnosed/untreated multiple myeloma.

INTRODUCTION: Bortezomib is a proteasome inhibitor that has shown important clinical efficacy either as a single agent or in combination in patients with multiple myeloma (MM). In the present protocol, bortezomib was combined with bendamustine and prednisone, in order to assess the efficacy and safety of this combination therapy in patients with newly diagnosed/untreated MM. METHODS: Between June 2006 and October 2013, 49 patients with newly diagnosed/untreated MM were treated with bendamustine 60 mg/m(2) on days 1 and 2, bortezomib 1.3 mg/m(2) on days 1, 4, 8 and 11, and prednisone 100 mg on days 1, 2, 4, 8 and 11 bendamustine, prednisone and bortezomib (BPV) once every 21 days. Patients were divided into three groups: group A (n = 19) consisted of patients with normal renal function or mild dysfunction (eGFR ≥ 60 ml/min), group B (n = 15) patients with moderate or severe renal dysfunction (eGFR 15-59 ml/min) and group C (n = 15) patients with renal failure/dialysis (eGFR <15 ml/min). RESULTS: A median number of two (range 1-5) BPV treatment cycles were given to the patients. The majority of the patients (n = 40, 82 %) responded after at least one cycle of BPV therapy with five stringent complete responses (CRs), nine near complete responses, 12 very good partial responses and 14 partial responses. Five patients had MR, three stable and one progressive disease. After a median observation time of 13 months, progression-free survival (PFS) and overall survival (OS) at 12 months were 92 and 94 %, respectively, for patients with normal renal function or mild renal dysfunction (group A) and 83 and 93 %, respectively, for patients with moderate or severe renal dysfunction (group B). Outcome for these patients was slightly better but not statistically significantly better than that for patients with renal failure/dialysis (group C), who had a PFS, and OS of 66 % (p = 0.08) and 73 % (p = 0.05), respectively. These results indicate that this BPV combination is feasible, effective and well tolerated in patients with newly diagnosed MM and normal or impaired renal function.

Low tumor burden is associated with early B-cell reconstitution and is a predictor of favorable outcome after non-myeloablative stem cell transplant for chronic lymphocytic leukemia.

Abstract Reconstitution, engraftment kinetics and tumor cell clearance were analyzed after reduced intensity conditioning hematopoietic cell transplant (RIC-HCT) in patients with chronic lymphocytic leukemia (CLL). Patients were transplanted from unrelated (n = 40) or related (n = 10) donors after fludarabine and 2 Gy total body irradiation followed by cyclosporine and mycophenolate mofetil. The vast majority of patients (96%) engrafted with absolute neutrophil count (ANC) > 0.5 × 10(9)/L at day + 22. CLL cells decreased (median 2%, range 0-69%) within 28 days, but disappeared by day + 180 after HCT. Donor T-cell chimerism increased to > 95% at day 56 and donor B-cell chimerism to 94% at day + 360. Overall survival was 51 ± 8%, incidence of progression 37 ± 7% and non-relapse related mortality (NRM) 30 ± 7% at 4 years. The most common causes of NRM were graft-versus-host disease (GvHD) (14%) and sepsis (6%). Disease status at HCT was significantly associated with early B-cell reconstitution (p = 0.04) and with increased risk of relapse/progression in univariate and multivariate analysis (p = 0.022). Tumor cells were undetectable by day + 180, although B-cell reconstitution did not occur until 1.5 years after RIC-HCT. The best predictors for progression-free survival (PFS) and overall survival (OS) were complete response (CR) or first partial response (PR1) and the absence of bulky disease at transplant, respectively.

Bendamustine and prednisone in combination with bortezomib (BPV) in the treatment of patients with relapsed or refractory multiple myeloma and light chain-induced renal failure.

INTRODUCTION: Serious renal failure represents a severe complication of multiple myeloma (MM), with an estimated 25-50 % of patients being affected. Both bortezomib and bendamustine have been identified as quickly acting, effective and well-tolerated drugs and might therefore constitute an adequate combination regimen for patients presenting with light chain-induced renal failure. METHODS: Between March 2005 and March 2013, 36 patients with relapsed/refractory MM and light chain-induced renal failure (creatinine clearance <60 ml/min) were treated with bendamustine 60 mg/m(2) on days 1 and 2, bortezomib 1.3 mg/m(2) on days 1, 4, 8 and 11 and prednisone 100 mg on days 1, 2, 4, 8 and 11 (BPV). Patients were divided according to severity of renal impairment into group A (n = 20) with moderate or severe renal dysfunction (eGFR 15-59 ml/min) and group B (n = 16) with renal failure/dialysis (eGFR <15 ml/min). RESULTS: Twenty-four patients (67 %) responded with three CR, three nCR, six VGPR and 12 PR. Six patients had minor response, two stable and four progressive disease. With a median follow-up period of 22 months, median progression-free survival (PFS) and overall survival (OS) for patients of group A were 10 and 25 months, respectively. This outcome was significantly better compared to patients of group B with a median PFS and OS of 3 and 7 months, respectively. Eleven patients showed a CRrenal, five a PRrenal and 15 a MRrenal. These results indicate that this BPV combination is feasible, effective and well tolerated in patients with relapsed/refractory MM and light chain-induced renal failure.

Combined bendamustine, prednisone and bortezomib (BPV) in patients with relapsed or refractory multiple myeloma.

INTRODUCTION: Bortezomib (Velcade) is a proteasome inhibitor that has shown important clinical efficacy either as a single agent or in combination with other cytostatic agents in multiple myeloma (MM). In the present protocol, bortezomib was combined with other active substances like bendamustine and prednisone (BPV), in order to assess the efficacy and toxicity of the combination therapy in patients with relapsed or refractory MM. METHODS: Between January 2005 and December 2011, 78 patients with relapsed or refractory MM were treated with bendamustine 60 (-120) mg/m(2) on days 1 and 2, bortezomib 1.3 mg/m(2) on days 1, 4, 8 and 11, and prednisone 100 mg on days 1, 2, 4, 8 and 11. The median number of prior therapies was 2 with a wide range of 1-9. Thirty-three patients had pre-existing severe thrombocytopenia and/or neutropenia (WHO grade 3 or 4). RESULTS: A median number of two (range 1-7) BPV treatment cycles were given to the patients. The majority of the patients (n = 54; 69 %) responded after at least one cycle of chemotherapy with 3 CR, 10 nCR, 10 VGPR and 31 PR. Median PFS and OS for patients without severe hematological toxicities due to previous treatments (n = 45) were 11 and 50 months, respectively. Outcome for these patients was significantly better than that for patients with severe hematological toxicities (grade 3 or 4, n = 33) with a PFS, and OS of 3 months (p < 0.05) and 5 months (p < 0.001), respectively. The regimen was well tolerated with few significant side effects in patients without severe hematological toxicities due to previous treatments. These results indicate that the combination of bortezomib, bendamustine and prednisone is well tolerated in patients with relapsed or refractory MM.

[The impact of an art therapy programme for cancer patients--an analysis from different points of view]. / Die Bedeutung einer kunsttherapeutischen Intervention für onkologische Patienten aus Sicht der Teilnehmer, der Kursleitung und der Supervisorin.

BACKGROUND: Art therapy is used in the whole field of psycho-oncological maintenance to support coping mechanisms with creative techniques. Previous studies stated effects of art therapy just by referring to the participants' ratings. This study wants to extend the perspective by including the views of all involved parties--participating patients, dropouts, art therapist and supervisor. PATIENTS AND METHODS: We developed and tested an art therapy programme for cancer patients. The participants' and dropouts' ratings were documented by using a questionnaire with open and closed questions upon completion of the intervention. The art therapist and the supervisor described their personal point of view. RESULTS: 74 patients took part in the intervention whereof 18 dropped out. Of these, 8 could be interviewed regarding the reasons for not participating further in the study. The dropouts evaluated the intervention positively(4/8) or could not make a final statement (3/8). 55 questionnaires were available from the 56 participants. They described the importance of the programme in several ways. Most of all, they reported of: stimulation of imagination (50/55), emotional stabilisation(48/55), enlargement of means of expression (45/55) and contact with other patients (42/55). The dropouts named several reasons for their decision to cancel: too intense focus on the disease(N = 3), modern drawing (N = 1), too much talks (N = 1) and too much sketching (N = 1) were some points of criticism. The art therapist as well as the supervisor emphasized activation as a main outcome for the participants. CONCLUSIONS: Positive effects of the intervention programme highlight the importance of establishing an art therapy in ambulant care. It enlarges the range of psychosocial maintenance and enables oncological patients to cope with the disease and its consequences with artistic means.
