Disease management of patients with immune thrombocytopenia-results of a representative retrospective survey in Germany.

Clinical research has resulted in an improvement of treatment options for patients with immune thrombocytopenia (ITP) over the last years. However, only few data exist on the real-life management of patients with ITP. To expand the knowledge, a multicenter, national survey was undertaken in 26 hematology practices distributed all over Germany. All patients with a diagnosis of ITP were documented using questionnaires, irrespective of the diagnosis date over a period of 2 years. Overall, data of 1023 patients were evaluated with 56% of patients being older than 60 years. Seventy-nine percent of the patients had chronic (> 12 months), 16% persistent (> 3-12 months), and 5% newly diagnosed (0-3 months) ITP. In 61% of cases, the disease lasted 3 or more years before survey documentation started. Main strategies applied as first-line therapy consisted of steroids in 45% and a "watch and wait" approach in 41% of patients. During second- and third-line strategies, treatment with steroids decreased (36% and 28%, respectively), while treatment modalities such as TPO-RAs increased (19% and 26%, respectively). As expected, patients with a low platelet count and thus a higher risk for bleeding and mortality received treatment (esp. steroids) more frequently during first line than those with a higher platelet count. Up to a third of patients were treated with steroids for more than a year. Overall, our study provides a cross-section overview about the current therapeutic treatment landscape in German ITP patients. The results will help to improve therapeutic management of ITP patients.

Prognostic model for newly diagnosed CLL patients in Binet stage A: results of the multicenter, prospective CLL1 trial of the German CLL study group.

The heterogeneity of early stage CLL challenges prognostication, and refinement of prognostic indices for risk-adapted management in this population is essential. The aim of the multicenter, prospective CLL1 trial was to explore a novel prognostic model (CLL1-PM) developed to identify risk groups, separating patients with favorable from others with dismal prognosis. A cohort of 539 clinically, biochemically, and genetically characterized Binet stage A patients were observed until progression, first-line treatment, or death. Multivariate analysis identified six independent factors associated with overall survival (OS) and time-to-first treatment (TTFT): del(17p), unmutated IGHV, del(11q), ß2-microglobulin >3.5 mg/dL, lymphocyte doubling time (LDT) <12 months, and age >60 years. These factors were integrated into the CLL1-PM, which stratified patients into four risk groups. The CLL1-PM was prognostic for OS and TTFT, e.g., the risk of treatment at 5 years was 85.9, 51.8, 27.6, and 11.3% for very low (0-1.5), low (2-4), high (4.5-6.5), and very high-risk (7-14) scores, respectively (P < 0.001). Notably, in addition to factors comprising CLL-IPI, we substantiated del(11q) and LDT as prognostic factors in early CLL. Altogether, our findings would be useful to effectively stratify Binet stage A patients, particularly within the scope of clinical trials evaluating novel agents.

Prophylaxis of chemotherapy-induced neutropenia and febrile neutropenia with lipegfilgrastim in patients with non-Hodgkin lymphoma (NADIR study).

OBJECTIVE: The prospective non-interventional study (NIS) NADIR was designed to evaluate both effectiveness and safety of prophylactic use of lipegfilgrastim (Lonquex® ), a glycopegylated granulocyte colony-stimulating factor, in cancer patients with different tumor entities undergoing chemotherapy in routine clinical practice. The primary objective was incidence of severe neutropenia, febrile neutropenia (FN), and neutropenia-associated complications. METHOD: NADIR was a national, multicenter, prospective NIS. RESULTS: Here, we present the data on patients with non-Hodgkin lymphoma (NHL). Final analysis comprised 337 NHL patients having received ≥1 administration of lipegfilgrastim. Primary prophylaxis with lipegfilgrastim was documented in 78.7% of patients with high risk to develop FN. In total, ≥1 severe neutropenia (grade 3/4) was reported in 115 (34.1%) patients and ≥1 event of FN documented in 15 (4.5%) patients. Grade 3/4 infections were reported in 22 (6.5%) patients overall. Most frequently reported adverse events (AEs) related to lipegfilgrastim in total were bone pain (5.4%), leukocytosis (2.1%), back pain (1.8%), platelet count decreased (1.2%), and myalgia (1.2%). Fatal serious AEs were documented in 9 (2.7%) patients; none were attributable to lipegfilgrastim. CONCLUSION: Prophylaxis or therapeutic intention with lipegfilgrastim in NHL patients in routine clinical practice showed similar effectiveness and safety as demonstrated in the pivotal trials.

Nivolumab maintenance after salvage autologous stem cell transplantation results in long-term remission in multiple relapsed primary CNS lymphoma.

Recurrence of primary central nervous system lymphoma (PCNSL) after high-dose chemotherapy with autologous stem cell transplantation (ASCT) usually has a poor overall prognosis with limited treatment options. Data on repeated ASCT are sparse. Checkpoint inhibitor maintenance therapy has also not been reported in PCNSL. Here, we report the first documented case of a successful third ASCT in second relapse of PCNSL. Whole-exome sequencing identified a hypermutated tumor genotype. Additionally, immunohistochemistry on pretreatment tumor tissue revealed infiltrates of PD-1+ cytolytic T cells. These alterations provided a rationale for subsequent nivolumab maintenance treatment. Therapy led to a long-term, ongoing complete remission. In eligible patients with recurrent MTX-sensitive PCNSL, multiple long-term remissions can be induced by repetition of high-dose MTX-based chemotherapy followed by autologous retransplantation. Subsequent immune checkpoint inhibitor maintenance therapy might be able to prolong or maintain remission.

Persistent impairments 3 years after (neo)adjuvant chemotherapy for breast cancer: results from the MaTox project.

PURPOSE: Although treatment for early breast cancer improved prognosis greatly, it can have significant long-term consequences, which must be considered during treatment decision. METHODS: 453 patients with neoadjuvant or adjuvant treatment intention were recruited into the MaTox project within the prospective, multicentre, population-based German TMK cohort study (Tumour Registry Breast Cancer) between 2008 and 2009. Patient-reported outcomes (PROs) on 26 treatment-related symptoms were assessed via a specifically designed questionnaire at 4 weeks, 6 months, 18 months and 3 years after start of systemic treatment. RESULTS: The results show that alterations in smell, taste and appetite were clearly improved 3 years after treatment. In contrast, post-surgical symptoms, restrictions in memory/attention, musculoskeletal system and polyneuropathy worsened substantially over time and were persistent after 3 years: 78% of the patients recorded impairment in memory, 73% muscle pain, 67% pain at the operated site and 57% paraesthesia in fingers or toes. A logistic regression model showed that risk factors for developing persistent paraesthesia symptoms were age, early paraesthesia symptoms and taxane-based therapy. CONCLUSIONS: Our data show that most patients with breast cancer have persistent impairments negatively influencing their daily life even 3 years after treatment. Furthermore, we highlight areas requiring special attention in follow-up care.

A Cross-Sectional Investigation of Fatigue, Mucositis, Hand-Foot Syndrome and Dysgeusia in Advanced Renal Cell Carcinoma Treatment: Final Results From the FAMOUS Study.

UNLABELLED: Treatment of metastatic renal cell carcinoma can be associated with adverse symptoms. The perception of fatigue, mucositis, hand-foot syndrome, and dysgeusia, and quality of life (QOL) was assessed in 63 oncologists and their patients receiving first-line treatment. Physicians underestimated the severity of the symptoms and the severity correlated with a lower QOL. A consistent assessment of symptoms in routine practice might improve QOL, adherence to treatment, and outcome. BACKGROUND: The management of symptoms associated with treatment of metastatic renal cell carcinoma (mRCC) is crucial to ensure treatment adherence and outcome. The perception of symptoms can vary between the treating physician and patient, leading to assumptions and subsequent changes in treatment, potentially affecting treatment effectiveness. The aim of the present cross-sectional study was to evaluate the perception of the common symptoms of fatigue, mucositis, hand-foot syndrome, and dysgeusia in patients with mRCC receiving systemic therapies in routine practice. PATIENTS AND METHODS: German patients receiving first-line systemic treatment for mRCC and their physicians were independently queried about the incidence and severity of fatigue, mucositis, hand-foot syndrome, and dysgeusia. Patients also completed the Functional Assessment of Cancer Therapy-General questionnaire to assess their quality of life (QOL). The effect of the 4 symptoms on QOL was analyzed using linear regression modeling. RESULTS: A total of 63 matching questionnaires were completed by both physicians and patients with first-line treatment. The incidence and severity of symptoms differed between the patients and physicians. Patients rated the severity of symptoms significantly higher than did the physicians. A greater severity of symptoms correlated with a lower QOL. In multivariate regression analysis, fatigue adversely affected overall QOL. CONCLUSION: Physicians underestimated the severity of common symptoms in patients with mRCC. The incorporation of patient-reported outcome measures into routine practice might increase awareness of patients' overall QOL and thereby potentially improve treatment adherence. A thorough evaluation of fatigue, its potential underlying causes, and active measures to manage fatigue could potentially improve patients' QOL.

NADIR: A Non-Interventional Study on the Prophylaxis of Chemotherapy-Induced Neutropenia Using Lipegfilgrastim - First Interim Analysis.

BACKGROUND: The non-interventional study (NIS) NADIR was designed to assess the effectiveness and safety of lipegfilgrastim, a novel glycopegylated granulocyte-colony stimulating factor, in reducing the risk of both febrile and severe neutropenia. METHODS: Here, the interim analysis of NIS Nadir performed under real-world conditions at 80 oncology practices across Germany is reported. For a patient to be included, lipegfilgrastim at a subcutaneous single dose of 6 mg had to be administered during at least 1 cycle of the chemotherapy under consideration. RESULTS: The interim analysis included 224 patients. Median patient age was 61.1 years (interquartile range 51.2-70.2 years). Main tumor type was breast cancer followed by lung cancer, and non-Hodgkin's lymphoma (46.0, 13.4, and 10.7%, respectively). When lipegfilgrastim was given as primary prophylaxis, no patient developed febrile neutropenia (FN). 1.3% of patients developed FN when primary prophylaxis was withheld. Only 68.6% of patients undergoing chemotherapy and at high risk (> 20%) of developing FN were treated with lipegfilgrastim during the first cycle, exposing disparity between real-world practices and current treatment guidelines. Lipegfilgrastim was well tolerated. The only grade 3/4 treatment-related adverse event was anemia in 1 patient. CONCLUSION: Lipegfilgrastim was effective and safe when administered for the prevention of chemotherapy-induced neutropenia under real-world conditions.

Poor efficacy and tolerability of R-CHOP in relapsed/refractory chronic lymphocytic leukemia and Richter transformation.

This phase II trial evaluated efficacy and tolerability of R-CHOP for up to 8 courses in Richter transformation (RT) and up to 6 courses in CLL plus autoimmune cytopenia (AIC) or high-risk (HR) features. HR was defined as fludarabine-refractoriness or early relapse (<36 months) after fludarabine-based treatment; 26 patients were included as HR, 19 patients had AIC, and 15 patients had RT. In the HR cohort, overall response rate was 54%, progression-free and overall survival were 9 and 21 months. In AIC patients overall response rate was 74%, progression-free and overall-survival were 10 and 41 months, respectively, and median increase in hemoglobin was 3.4 g/L. RT patients responded in 67%, progression-free was 10 and overall survival 21 months. The most common adverse events were hematologic toxicities in 92%. Severe infections occurred in 28%. Treatment was discontinued early in 45% of all patients mainly as a result of toxicity. This trial shows that R-CHOP has no role in treating complicated CLL. R-CHOP is associated with significant toxicities and fairly low efficacy compared with almost every other CLL-regimen. In RT, it might still be used as an induction therapy before allogeneic stem cell transplantation.

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.

Epoetin alfa treatment results in clinically significant improvements in quality of life in anemic cancer patients when referenced to the general population.

PURPOSE: Anemia, highly common among cancer patients, is often an underlying cause of cancer-related fatigue and other quality-of-life (QOL) deficits. Although randomized clinical trials have shown that treatment with epoetin alfa increases hemoglobin levels, reduces fatigue, lessens transfusion requirements, and improves overall QOL, cancer-related anemia and fatigue remain undertreated. This is, in part, because scales and measures of QOL are still relatively unfamiliar to most clinicians and because population-based reference ranges are lacking, thus making clinical trial results difficult to interpret. METHODS: To aid in the interpretation of QOL results from clinical trials, we administered the Functional Assessment of Cancer Therapy-Anemia (FACT-An) QOL instrument to a nationally representative sample of 1,400 people using an Internet survey panel in the United States. We then compared the FACT-An data from the Internet survey with the QOL data of a 375-patient randomized, double-blind clinical trial evaluating epoetin alfa versus placebo in anemic cancer patients. RESULTS: FACT-An, as administered to the survey population, displayed good psychometric properties and was able to discriminate between respondents with histories of specified illnesses, including anemia and cancer, and those without. Comparison of the population norm and clinical trial data showed that treatment with epoetin alfa resulted in clinically meaningful as well as statistically significant improvements in QOL (P <.01). CONCLUSION: Reliable population norm data are now available to aid in the interpretation of clinical trial results where the FACT-An questionnaire is administered. In the clinical trial, treatment with epoetin alfa overcame much of the QOL deficit seen in anemic cancer patients compared with the norm population sample.
