Association between serum IgG concentrations and the incidence of infections in patients with chronic lymphocytic leukemia and secondary immunodeficiency under treatment with Privigen.

OBJECTIVE: To investigate the association between serum immunoglobulin G (IgG) concentrations and the incidence of infections in patients with chronic lymphocytic leukemia (CLL) and secondary immunodeficiency receiving treatment with Privigen. MATERIALS AND METHODS: Data was analyzed from a non-interventional study conducted in 31 centers in Germany and 1 in Austria. Adult CLL patients with hypogammaglobulinemia and recurrent infections were allowed to enter the study upon signing informed consent, if a prior decision for treatment with Privigen had been made. All infections requiring an antimicrobial treatment were subject to analysis. Patients were stratified according to their mean post-baseline serum IgG trough levels in a group with lower IgG trough levels (≤ 5.0 g/L), and a group with higher IgG trough levels (> 5.0 g/L). RESULTS: Overall, 89 patients and 840 treatment cycles were analyzed. Up to 11 treatment cycles (average duration 29 days) were documented in each patient. In the group with higher IgG trough levels (> 5.0 g/L, N = 72), significantly fewer infections were observed than in the group with lower IgG trough levels (≤ 5.0 g/L, N = 17), including fewer severe and serious infections. The Privigen dosage was a major determinant of the post-baseline serum IgG levels. Overall tolerability of Privigen was assessed as very good or good in 91% of patients. CONCLUSION: This analysis confirms the association of serum IgG trough levels with the incidence of infections and highlights the importance of careful monitoring of IgG levels during treatment of secondary immunodeficiencies in CLL patients.

Low incidence of tumor lysis syndrome in elderly patients with chronic lymphocytic leukemia treated with venetoclax under real-world conditions: results from the prospective observational VeRVe study.

Venetoclax is active in both frontline and relapsed/refractory settings for the treatment of chronic lymphocytic leukemia (CLL). Although the prevalence and severity of tumor lysis syndrome (TLS) are well characterized in clinical trials, laboratory and clinical TLS remain relatively unexplored in real-world clinical practice.In this prospective, real-world observational study, we aimed to determine the incidence and outcomes of TLS in patients with CLL receiving venetoclax outside a clinical trial. The study (VeRVe) was conducted in centers in Austria, Germany, and Switzerland.Two hundred and thirty-nine patients were treated according to local label with at least one dose of venetoclax. Patient demographics, baseline characteristics, and blood chemistry at baseline were documented, and descriptive statistical analyses were conducted.Seventy eight patients (33%) were treated with venetoclax monotherapy, 101 (42%) with venetoclax in combination with rituximab and 60 (25%) with venetoclax in combination with obinutuzumab. In all cases, the TLS risk mitigation strategy adhered to the ramp-up protocol. Median age was 73 years and 66% of patients were male. The majority of patients (75%) had relapsed/refractory CLL, 63/192 (32.8%) patients tested had a del(17p) and 93/134 (69.4%) patients tested had unmutated immunoglobulin heavy chain variable region gene (IGHV). Clinical TLS occurred in 5 patients (2.1%) and laboratory TLS occurred in 15 patients (6.3%). Ten patients received specific treatment, of which 6 were hospitalized. There were no deaths due to a TLS event and venetoclax was well-tolerated. Of the 5 clinical TLS events reported, none were fatal or resulted in renal failure (NCT03342144, registered on Nov 10, 2017).

REFLECT: prospective multicenter non-interventional study evaluating the effectiveness and safety of Sandoz rituximab (SDZ-RTX; Rixathon®) in combination with CHOP for the treatment of patients with previously untreated CD20-positive diffuse large B-cell lymphoma.

Background: REFLECT is the first prospective study of Sandoz biosimilar rituximab (SDZ-RTX) in patients with diffuse large B-cell lymphoma (DLBCL). Objective: To evaluate the 2-year effectiveness and safety of SDZ-RTX as first-line treatment for DLBCL. Design: Real-world, multicenter, open-label, single-arm, non-interventional, post-approval study of SDZ-RTX in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with treatment-naïve CD20­positive DLBCL. Methods: Treatment-naïve, CD20-positive adult patients (⩾18 years) with DLBCL eligible for therapy with R-CHOP were treated with SDZ-RTX-CHOP every 2 or 3 weeks for 6-8 cycles. The effectiveness of SDZ-RTX was measured by the complete response (CR) rate at the end of R-CHOP treatment, as assessed by the treating physician. Progression-free survival (PFS) was assessed at 24 months. Results: A total of 169 patients [52.1% female, median (range) age 70 (24-94) years] with DLBCL were included in the full analysis set. At baseline, 19.5% and 24.3% of patients had Ann Arbor disease stage III or IV, respectively, and most patients (80.5%) had Eastern Cooperative Oncology Group Performance Status of 0 or 1. A total of 100 (59.2%) patients completed the 24-month observation period. In total, 110 [65.1%; 95% confidence interval (CI): 57.4-72.3] patients achieved CR as best response and 50 (29.6%; 95% CI: 22.8-37.1) patients achieved partial response. Overall best response rate was 94.7% (95% CI: 90.1-97.5). One-year PFS was 84.9% (95% CI: 78.2-89.6), while 2-year PFS was 78.5% (95% CI: 70.9-84.4); median PFS was not reached within the observational period. A total of 143 (84.6%) patients experienced ⩾1 adverse event, 53 (31.4%) of which were suspected to be related to study drug. Conclusion: This real-world, 2-year study reconfirms that first-line treatment of CD20-positive DLBCL with R-CHOP using SDZ-RTX is effective and well tolerated. Registration: N/A.

REFLECT: A study evaluating Sandoz biosimilar rituximab (Rixathon ^® ) in combination with CHOP for the treatment of patients with previously untreated diffuse large B-cell lymphoma Why was this study done? • Biosimilars are biologic medicines that are highly similar to a reference biologic medicine that is already approved and has been used in patients for several years. • The REFLECT study was the first study of a biosimilar medicine (Sandoz biosimilar rituximab) in patients with a type of lymphatic cancer called diffuse large B-cell lymphoma (DLBCL). What did the researchers do? • Sandoz biosimilar rituximab was given as part of the standard treatment (cyclophosphamide, doxorubicin, vincristine, and prednisone; R-CHOP) in patients with DLBCL who had not received treatment before. • The researchers aimed to evaluate how well Sandoz biosimilar rituximab worked over a 2-year period. • The researchers also aimed to look at the safety of Sandoz biosimilar rituximab. • Patients with DLBCL had to be ⩾18 years of age, in need of treatment, and were classed as suitable for treatment with R-CHOP by their doctor. • Patients were treated with R-CHOP including Sandoz biosimilar rituximab every 2 or 3 weeks for 6­8 cycles. What did the researchers find? • A total of 169 patients with DLBCL were included in the study. • Just over half (52%) were female and the average age was 67 years. • Nearly 6 out of 10 (59%) patients completed the 2-year study. • More than 6 out of 10 (65%) patients achieved complete response and 3 out of 10 (30%) achieved partial response. • The overall response rate was 95%. • One-year progression-free survival was 85%, and 2-year progression-free survival was 79%. • Regarding safety, 85% of patients experienced at least one adverse event; just over 3 out of 10 (31%) of these were suspected to be related to the study drug. What do the findings mean? • This 2-year study shows that R-CHOP including Sandoz biosimilar rituximab is effective and well tolerated as the first treatment given to patients with DLBCL.

PRECYCLE: multicenter, randomized phase IV intergroup trial to evaluate the impact of eHealth-based patient-reported outcome (PRO) assessment on quality of life in patients with hormone receptor positive, HER2 negative locally advanced or metastatic breast cancer treated with palbociclib and an aromatase inhibitor or palbociclib and fulvestrant.

BACKGROUND: Efficacy and quality of life (QoL) are key criteria for therapy selection in metastatic breast cancer (MBC). In hormone receptor positive (HR +) human epidermal growth factor receptor 2 negative (HER2 -) MBC, addition of targeted oral agents such as everolimus or a cycline-dependent kinase 4/6 (CDK 4/6) inhibitor (e.g., palbociclib, ribociclib, abemaciclib) to endocrine therapy substantially prolongs progression-free survival and in the case of a CDK 4/6i also overall survival. However, the prerequisite is adherence to therapy over the entire course of treatment. However, particularly with new oral drugs, adherence presents a challenge to disease management. In this context, factors influencing adherence include maintaining patients' satisfaction and early detection/management of side effects. New strategies for continuous support of oncological patients are needed. An eHealth-based platform can help to support therapy management and physician-patient interaction. METHODS: PreCycle is a multicenter, randomized, phase IV trial in HR + HER2 - MBC. All patients (n = 960) receive the CDK 4/6 inhibitor palbociclib either in first (62.5%) or later line (37.5%) together with endocrine therapy (AI, fulvestrant) according to national guidelines. PreCycle evaluates and compares the time to deterioration (TTD) of QoL in patients supported by eHealth systems with substantially different functionality: CANKADO active vs. inform. CANKADO active is the fully functional CANKADO-based eHealth treatment support system. CANKADO inform is a CANKADO-based eHealth service with a personal login, documentation of daily drug intake, but no further functions. To evaluate QoL, the FACT-B questionnaire is completed at every visit. As little is known about relationships between behavior (e.g., adherence), genetic background, and drug efficacy, the trial includes both patient-reported outcome and biomarker screening for discovery of forecast models for adherence, symptoms, QoL, progression free survival (PFS), and overall survival (OS). DISCUSSION: The primary objective of PreCycle is to test the hypothesis of superiority for time to deterioration (TTD) in terms of DQoL = "Deterioration of quality of life" (FACT-G scale) in patients supported by an eHealth therapy management system (CANKADO active) versus in patients merely receiving eHealth-based information (CANKADO inform). EudraCT Number: 2016-004191-22.

Early versus Delayed Tumor-Specific Therapy and Survival in Patients with Lung Cancer: A Retrospective Study.

INTRODUCTION: The timing of tumor-specific palliative therapy and its influence on the survival of patients with stage IV lung cancer remain unclear. METHODS: 375 patients with stage IV lung cancer who experienced an early or delayed therapy (early or delayed therapy group [TG]) were investigated using histology and ECOG performance score (ECOG-PS)-related subgroups. Kaplan-Meier and Cox regression analyses were used for survival analyses. RESULTS: Patients in the early TG had a significantly shorter median overall survival (OS) than those in the delayed TG (6 vs. 11 months). Patients with an ECOG-PS of ≥1 were significantly more present in the early TG than in the delayed TG (66.8 vs. 51.9%). But an early therapy was also significantly associated to a shorter median OS in ECOG-matched subgroups (ECOG-PS of 0, 7 vs. 23 months; ECOG ≥1, 6 vs. 8 months). An early therapy was associated to a significantly worse median OS in histological subgroups (NSCLC, 5 vs. 11 months; SCLC, 7 vs. 11 months) and was an independent risk factor in uni- and multivariate analyses. CONCLUSIONS: An early initiation of cancer-specific therapy was associated with a shorter survival time in palliative lung cancer patients, independent of the ECOG-PS and histological subtype.

Patient assessment and feasibility of treatment in older patients with cancer: results from the IN-GHO® Registry.

PURPOSE: Predicting feasibility of treatment in older patients with cancer is a major clinical task. The Initiative Geriatrische Hämatologie und Onkologie (IN-GHO®) registry prospectively collected data on the comprehensive geriatric assessment (CGA), physician's and patient's-self assessment of fitness for treatment, and the course of treatment in patients within a treatment decision aged ≥ 70 years. PATIENTS AND METHODS: The registry included 3169 patients from 93 centres and evaluated clinical course and treatment outcomes 2-3 and 6 months after initial assessment. Fitness for treatment was classified as fit, compromised and frail according to results of a CGA, and in addition by an experienced physician's and by patient's itself. Feasibility of treatment (termed IN-GHO®-FIT) was defined as a composite endpoint, including willingness to undergo the same treatment again in retrospect, no modification or unplanned termination of treatment, and no early mortality (within 90 days). RESULTS: CGA classified 30.0% as fit, 35.8% as compromised, and 34.2% as frail. Physician's and patient's-self assessment classified 61.8%/52.3% as fit, 34.2%/42.4% as compromised, and 3.9%/5.3%, as frail, respectively. Survival status at day 180 was available in 2072 patients, of which 625 (30.2%) had died. After 2-3 months, feasibility of treatment could be assessed in 1984 patients. 62.8% fulfilled IN-GHO®-FIT criteria. Multivariable analysis identified physician's assessment as the single most important item regarding feasibility of treatment. CONCLUSION: Geriatricians were involved in 2% of patients only. Classification of fitness for treatment by CGA, and physician's or patient's-self assessment showed marked discrepancies. For the prediction of feasibility of treatment no single item was superior to physician's assessment. However CGA was not performed by trained geriatricians.

Health status and infections in patients with symptomatic primary and secondary immunoglobulin G (IgG) deficiencies receiving intravenous IgG replacement.

BACKGROUND: The effects of intravenous immunoglobulin G replacement on perceived health and infection susceptibility of patients suffering from immunoglobulin G (IgG) deficiencies should be evaluated in a prospective analysis. METHODS: Patients with symptomatic primary or secondary IgG deficiencies were interviewed prior to the first IgG infusion (t0) and over the course of their treatment (t1 - t6). The respondents rated their current health using a 100 point scale (EQ-5D-5L), ranging from 0 ('worst imaginable health') to 100 ('best imaginable health'). The patients also provided information on the frequency of infections and of infections requiring antibiotics in the past 8 weeks. A healthy control group (CG) without oncologic diseases answered the questions once. RESULTS: One hundred six patients with a median age of 65 years (21-85 years) were investigated. The median serum IgG concentration changed from 500 mg/dl (t0) to 772 mg/dl (t6). The mean number of infections and of infections requiring antibiotics decreased during IgG replacement significantly. Current health according to EQ-5D-5L improved from 57 (t0) to 68 (t6), compared to 73 in the CG. CONCLUSION: During the course of IgG replacement patients reported fewer and less severe infections. Their health assessment improved but still was inferior to the healthy CG.

Rare lymphomas in routine practice-Treatment and outcome in Waldenström's macroglobulinaemia in the prospective German Tumour Registry Lymphatic Neoplasms.

Waldenström's macroglobulinaemia (WM) is a rare indolent B-cell lymphoma for which only little prospective phase III evidence exists. Thus, real world data are important to provide insight into treatment and survival. We present here data on choice and outcome of systemic treatment of patients with WM treated in German routine practice. In total, 139 patients with WM who had been documented in the prospective clinical cohort study Tumour Registry Lymphatic Neoplasms (NCT00889798) were included into this analysis. We analysed the most frequently used first-line and second-line treatments between 2009 and 2017 and examined best response, progression-free survival (PFS) and overall survival (OS). Bendamustine plus rituximab, with a median of six cycles, was by far the most frequently used first-line treatment (81%). Second-line treatment was more heterogenous and mainly based on bendamustine, cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP), fludarabine or ibrutinib, the latter approved in 2014. Three-year PFS from start of first-line treatment was 83% (95% confidence interval [CI] 74%-88%), 3-year OS was 87% (95% CI 80%-92%). These prospective data give valuable insights into the management and outcome of non-selected patients with WM treated in German routine practice. In the lack of prospective phase III clinical trials, real world data can help bridging the gap of evidence.

Real-world use and acceptance of rituximab biosimilars in non-Hodgkin lymphoma in an oncologist network in Germany.

Aim: Present real-world data for rituximab (biosimilar and reference)-containing regimens in extrapolated indications in non-Hodgkin lymphoma (NHL)/chronic lymphocytic leukemia (CLL). Patients & methods: Data collected from office-based oncologic practices in Germany (July 2017-June 2019). Results: Of 1741 patients, 1241 had NHL; 500 had CLL. Of 7595 therapy cycles, 28.3% used reference rituximab; 55.2% used rituximab biosimilars; 2.0% used subcutaneous rituximab; 14.5% used rituximab, not otherwise specified. Rituximab biosimilars were used across all indications; 57.3% of cycles were administered in extrapolated indications. Over 24 months, the proportion of rituximab prescriptions that were for biosimilars increased from 12.0 to 83.0%. Conclusion: Our real-world data in NHL and CLL depicts increasing use of rituximab biosimilars across multiple treatment protocols, including extrapolated indications.

High adherence of patients with multiple myeloma who receive treatment with immunomodulatory drugs (IMIDS) in hematology/oncology group practices in Germany.

PURPOSE: Immunomodulatory drugs (IMIDS) have changed the treatment and outcome of patients suffering from multiple myeloma. However, with the oral administration adherence becomes an issue. Since there is no "gold standard" in measuring adherence, we assessed the adherence of myeloma patients with the help of different data sources. METHODS: All patients who have been receiving IMIDS for at least 3 months were eligible. Computer assisted personal interviews of patients and, if possible, their caregivers were carried out. Attending oncologists evaluated the patient's adherence with the help of a standardized questionnaire. In addition, a retrospective analysis of prescription data was conducted. All data were analyzed statistically using SPSS. RESULTS: One hundred myeloma patients, 35% female, 65% male, with a median age of 70 years (37-86) were interviewed. Prescription data could be evaluated in terms of adherence in 78 patients (78%), 56 caregivers could be questioned (56%). Ninety-seven percent of patients rated themselves as adherent in taking IMIDS. Data from treating oncologists, caregivers and prescriptions supported this result. IMID therapies were rated as very effective and significant, toxicities were acceptable and dosing regimens simple/uncomplicated. CONCLUSIONS: Myeloma patients seem to be highly adherent to IMID treatments.

Home administration of filgrastim (Nivestim™) in primary prophylaxis of chemotherapy-induced febrile neutropenia.

BACKGROUND: The granulocyte-colony stimulating factor (G-CSF) biosimilar filgrastim (Nivestim™) reduces the duration and severity of neutropenia and the frequency of occurrence of febrile neutropenia (FN). Administration of this biosimilar filgrastim and the patient population receiving it at home have not been sufficiently documented in day-to-day medical practice. Insight into home administration may help optimize the management of FN in this setting, potentially at a reduced cost and patient burden vs hospital administration. MATERIALS AND METHODS: This was a prospective, non-interventional, non-comparative, multisite study involving 171 patients across 29 sites treated with at least one dose of filgrastim. Mean age was 59.3 years, and most patients were female and G-CSF-naïve. The data collected originated from paper-based patient questionnaires and routine documentation by the treating physicians. The primary endpoint was the characterization of patients treated with filgrastim. Secondary endpoints were satisfaction with filgrastim, effectiveness, safety and tolerability, and compliance with prescription. RESULTS: Most patients had solid tumors (95.9%), mainly located in the breast, while 4.7% had malignant hematological disease. Solid tumors were recorded as grade 1 (7.9%), grade 2 (28.0%), grade 3 (45.7%), and grade 4 (3.0%), and the majority of patients classified at TNM Stages I and II. Many patients (71.0%) could self-inject filgrastim and 72.2% found the handling instructions "extremely straightforward and easy to understand" at least once. Nearly all (99.4%) patients found the syringes "easy to use" at least once and 91.7% were willing to continue home administration. The mean patient satisfaction score for home administration was 1.9±0.9, ranging from 1 (very satisfied) to 6 (absolutely dissatisfied). No cases of neutropenia were observed and only one event of FN occurred. CONCLUSION: Home-based prophylaxis for FN with filgrastim was found to be effective, well tolerated, and well received by patients (ClinicalTrials.gov Identifier: NCT02956967).

Geriatric assessment and biomarkers in patients with metastatic breast cancer receiving first-line mono-chemotherapy: Results from the randomized phase III PELICAN trial.

OBJECTIVES: To determine predictive/prognostic factors for patients with metastatic breast cancer (MBC) receiving first-line monochemotherapy using biomarker analysis and geriatric assessment (GA). MATERIALS AND METHODS: Karnofsky Performance Status (KPS) and GA as clinical parameters, and prognostic inflammatory and nutritional index (PINI), and Glasgow prognostic score (GPS) as biomarkers were analyzed for association with clinical outcome within the randomized phase III PEg-LIposomal Doxorubicin vs. CApecitabin iN MBC (PELICAN) trial of first-line pegylated liposomal doxorubicin (PLD) or capecitabine. RESULTS: Of 210 patients, 38% were >65years old. GA (n=152) classified 74% as fit, 10% as compromised, and 16% as frail. Biomarkers showed no age dependency. In multivariate analysis (n=70) KPS, GA, cumulative illness rating scale-geriatrics (CIRS-G), and GPS were significantly associated with time to progression, and KPS, CIRS-G, and instrumental activities of daily living (IADL) from GA, and PINI showed a significant correlation with overall survival. CONCLUSION: GA evaluation was feasible. KPS significantly correlated with efficacy outcomes. Items of a GA and biomarkers of inflammation and nutrition may have prognostic significance in patients with MBC.

A randomized phase III study evaluating pegylated liposomal doxorubicin versus capecitabine as first-line therapy for metastatic breast cancer: results of the PELICAN study.

PURPOSE: The PELICAN trial evaluates for the first time efficacy and safety of pegylated liposomal doxorubicin (PLD) versus capecitabine as first-line treatment of metastatic breast cancer (MBC). METHODS: This randomized, phase III, open-label, multicenter trial enrolled first-line MBC patients who were ineligible for endocrine or trastuzumab therapy. Cumulative adjuvant anthracyclines of 360 mg/m2 doxorubicin or equivalent were allowed. Left ventricular ejection fraction of >50 % was required. Patients received PLD 50 mg/m2 every 28 days or capecitabine 1250 mg/m2 twice daily for 14 days every 21 days. The primary endpoint was time-to-disease progression (TTP). RESULTS: 210 patients were randomized (n = 105, PLD and n = 105, capecitabine). Adjuvant anthracyclines were given to 37 % (PLD) and 36 % (capecitabine) of patients. No significant difference was observed in TTP [HR = 1.21 (95 % confidence interval, 0.838-1.750)]. Median TTP was 6.0 months for both PLD and capecitabine. Comparing patients with or without prior anthracyclines, no significant difference in TTP was observed in the PLD arm (log-rank P = 0.64). For PLD versus capecitabine, respectively, overall survival (median, 23.3 months vs. 26.8 months) and time-to-treatment failure (median, 4.6 months vs. 3.7 months) were not statistically significantly different. Compared to PLD, patients on capecitabine experienced more serious adverse events (P = 0.015) and more cardiac events among patients who had prior anthracycline exposure (18 vs. 8 %; P = 0.31). CONCLUSION: Both PLD and capecitabine are effective first-line agents for MBC.

Compatibility of Biosimilar Filgrastim with Cytotoxic Chemotherapy during the Treatment of Malignant Diseases (VENICE): A Prospective, Multicenter, Non-Interventional, Longitudinal Study.

INTRODUCTION: Febrile neutropenia (FN) is a serious and frequent complication of cytotoxic chemotherapy. Biosimilar filgrastim (Nivestim™, Hospira Inc, A Pfizer Company, Lake Forest, IL, USA) is a granulocyte-colony stimulating factor licensed for the treatment of neutropenia and FN induced by myelosuppressive chemotherapy. The primary goal of this VENICE study (ClinicalTrials.gov identifier, NCT01627990) was to observe the tolerability, safety and efficacy of biosimilar filgrastim in patients receiving cancer chemotherapy. METHODS: This was a prospective, multicenter, non-interventional, longitudinal study. Consenting adult patients with solid tumors or hematologic malignancies for whom cytotoxic chemotherapy and treatment with biosimilar filgrastim was planned were enrolled. RESULTS: Among the enrolled patients (N = 386), 81% were female, with a median age (range) of 61 (22-92) years, with 39% >65 years old. Most patients (n = 338; 88%) had solid tumors and the remainder (n = 49; 13%) had hematological malignancies. The majority of the patients (64%) received biosimilar filgrastim as primary prophylaxis and 36% as secondary prophylaxis. At the follow-up visits, for the majority of patients (95.6%) there had been no change in chemotherapy dose due to FN. For two patients (0.5%) the chemotherapy was discontinued due to FN and for four patients (1.0%) the chemotherapy dose was reduced due to FN. For the majority of patients (96.9%) the chemotherapy cycle following the first biosimilar filgrastim treatment was not delayed due to FN. For 3 patients (0.8%), the chemotherapy was delayed following the first biosimilar filgrastim treatment. Less than one-third (29.8%) of the patients experienced ≥1 adverse event that was at least potentially related to biosimilar filgrastim treatment. CONCLUSIONS: Biosimilar filgrastim was effective and well-tolerated in both the primary and secondary prophylactic setting in patients undergoing chemotherapy for solid tumors and hematological malignancies.

Clinical and immunologic phenotype associated with activated phosphoinositide 3-kinase δ syndrome 2: A cohort study.

BACKGROUND: Activated phosphoinositide 3-kinase δ syndrome (APDS) 2 (p110δ-activating mutations causing senescent T cells, lymphadenopathy, and immunodeficiency [PASLI]-R1), a recently described primary immunodeficiency, results from autosomal dominant mutations in PIK3R1, the gene encoding the regulatory subunit (p85α, p55α, and p50α) of class IA phosphoinositide 3-kinases. OBJECTIVES: We sought to review the clinical, immunologic, and histopathologic phenotypes of APDS2 in a genetically defined international patient cohort. METHODS: The medical and biological records of 36 patients with genetically diagnosed APDS2 were collected and reviewed. RESULTS: Mutations within splice acceptor and donor sites of exon 11 of the PIK3R1 gene lead to APDS2. Recurrent upper respiratory tract infections (100%), pneumonitis (71%), and chronic lymphoproliferation (89%, including adenopathy [75%], splenomegaly [43%], and upper respiratory tract lymphoid hyperplasia [48%]) were the most common features. Growth retardation was frequently noticed (45%). Other complications were mild neurodevelopmental delay (31%); malignant diseases (28%), most of them being B-cell lymphomas; autoimmunity (17%); bronchiectasis (18%); and chronic diarrhea (24%). Decreased serum IgA and IgG levels (87%), increased IgM levels (58%), B-cell lymphopenia (88%) associated with an increased frequency of transitional B cells (93%), and decreased numbers of naive CD4 and naive CD8 cells but increased numbers of CD8 effector/memory T cells were predominant immunologic features. The majority of patients (89%) received immunoglobulin replacement; 3 patients were treated with rituximab, and 6 were treated with rapamycin initiated after diagnosis of APDS2. Five patients died from APDS2-related complications. CONCLUSION: APDS2 is a combined immunodeficiency with a variable clinical phenotype. Complications are frequent, such as severe bacterial and viral infections, lymphoproliferation, and lymphoma similar to APDS1/PASLI-CD. Immunoglobulin replacement therapy, rapamycin, and, likely in the near future, selective phosphoinositide 3-kinase δ inhibitors are possible treatment options.

Characteristics of episodic breathlessness as reported by patients with advanced chronic obstructive pulmonary disease and lung cancer: Results of a descriptive cohort study.

BACKGROUND: Episodic breathlessness is one form of refractory breathlessness. Better understanding of the symptom is necessary for effective management. AIM: The aim was to describe the characteristics of episodic breathlessness in patients with advanced chronic obstructive pulmonary disease or lung cancer. DESIGN: This is a longitudinal cohort study. Outcomes were assessed monthly by up to 13 telephone interviews: peak severity (modified Borg scale: 0-10), duration, frequency, and timing of breathlessness episodes. Data from each episode were pooled and analyzed using descriptive statistics. Associations between outcomes were explored by correlation coefficients. SETTING/PARTICIPANTS: Patients with chronic obstructive pulmonary disease (Global Initiative for Chronic Obstructive Lung Disease classification stage III or IV) or primary lung cancer (any stage) were recruited in two inpatient units (internal medicine) and two outpatient clinics in Oldenburg, Germany. RESULTS: A total of 82 patients (50 chronic obstructive pulmonary disease, 32 lung cancer), mean age (standard deviation) 67 years (8 years) and 36% female, were included reporting on 592 breathlessness episodes (chronic obstructive pulmonary disease: 403, lung cancer: 189). Peak severity was perceived significantly higher in chronic obstructive pulmonary disease patients than in lung cancer patients (mean (standard deviation) Borg scale: 6.2 (2.1) vs 4.2 (1.9); p < 0.001). Episodes described by chronic obstructive pulmonary disease patients were longer than those described by lung cancer patients (median (range): 7 min (0-600) vs 5 min (0.3-120), p = 0.002)). Frequency was similar and most often daily in both groups. Severity and frequency of episodes were correlated in lung cancer patients (r = 0.324, p = 0.009). CONCLUSION: Most breathlessness episodes are short (minutes) and severe with significant differences between chronic obstructive pulmonary disease and lung cancer patients. Effective management strategies are warranted to improve symptom relief and coping.

[WINHO quality indicators for outpatient oncology care in Germany]. / WINHO-Qualitätsindikatoren für die ambulante onkologische Versorgung in Deutschland.

The aim of the WINHO indicators project is to describe and enhance the quality of outpatient oncology care in Germany with indicators. This paper deals with the development of a set of evidence- and consensus-based meaningful indicators to assess the quality of outpatient oncology care in Germany. These indicators are intended to be applied in assessments of quality of patient care in oncology practices, in quality reports and in peer-to-peer benchmarking. A set of 272 already existing indicators was identified through internet and literature searches. After redundancy reduction and addition of newly developed indicators for areas of ambulatory oncology care that were not yet covered, a preliminary set of 67 indicators was established. The further development of the indicator set was based on a modified version of the two-step RAND/UCLA expert evaluation method, which has been internationally established for developing quality indicator sets. The indicators were modified after the first round of ratings. After completing and assessing the second round of ratings, a set of 46 homogeneously positively rated quality indicators is now available for outpatient oncology care in Germany.

Cabazitaxel plus prednisone for metastatic castration-resistant prostate cancer progressing after docetaxel: results from the German compassionate-use programme.

BACKGROUND: Cabazitaxel (Cbz) is an approved second-line treatment in metastatic castration-resistant prostate cancer (mCRPC) following docetaxel therapy with a significant survival benefit compared with mitoxantrone. However, grade 3/4 toxicities were reported in 82% of patients. OBJECTIVE: To report on the safety results of mCRPC patients treated within a compassionate-use programme in Germany. DESIGN, SETTING, AND PARTICIPANTS: A total of 111 patients with a mean age of 67.9 yr (range: 49-81 yr) and progressive mCRPC were included. Patients had received a mean number of 12.7 ± 10.8 cycles (range: 6-69 cycles) of docetaxel with a mean cumulative dose of 970.9 mg/m(2); mean time from last docetaxel application to progression was 6.95 mo (range: 2-54 mo). Of the patients, 31.5% progressed by prostate-specific antigen (PSA) increase only; the remainder had a combination of PSA increase and clinical progression. INTERVENTION: Cbz at a dosage of 25mg/m(2) intravenously every 3 wk combined with 5mg of oral prednisone twice a day. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Treatment-associated toxicity was the primary study end point; progression-free and overall survival were secondary end points. A descriptive statistical analysis was performed. RESULTS AND LIMITATIONS: Patients received a mean number of 6.5 ± 2.2 cycles of Cbz and a mean cumulative dose of 160.3 ± 51.5mg/m(2). Grade 3 and 4 treatment-emergent adverse events were recorded in 34 patients (30.6%) and 18 patients (16.2%), respectively. Grade 3/4 anaemia, neutropenia, and thrombocytopenia were reported in 4.5%, 7.2%, and 0.9% of the patients, respectively. Neutropenic fever was reported in 1.8% of the patients. Grade 3/4 gastrointestinal toxicity was identified in 4.5% of the patients. Three patients died because of Cbz-related toxicity. Granulocyte colony-stimulating growth factors were used in 17.1% of patients. The limitations are due to the nonrandomised nature of the trial. CONCLUSIONS: Treatment with Cbz is tolerable and is associated with a low incidence of serious adverse events in a real-world patient population with CRPC. The outcome of serious adverse events can be minimised with proactive treatment management and conscientious monitoring.

Bortezomib in relapsed multiple myeloma: results of a non-interventional study by office-based haematologists.

BACKGROUND: In Germany, bortezomib is approved for the therapy of relapsed multiple myeloma since 2004. The data which had led to the approval were based on strictly selected patients. However, no data had been recorded on bortezomib in routine practice. MATERIALS AND METHODS: In this non-interventional study, bortezomib was studied under routine conditions by office-based haematologists. Data were obtained prospectively following a protocol approved by the responsible Ethics Committee. Treatment followed the prescribing information and was documented for a maximum of 8 cycles. Any therapeutic or diagnostic intervention was left to the discretion of the attending physician. The primary endpoints were efficacy and safety. RESULTS: Overall remission rate was 61% in patients evaluable for efficacy. Response rates were not significantly different between patients < or = 70 and >70 years of age, nor between patients with and without renal impairment. The median time to best response was 3 cycles. Serious adverse events included thrombocytopenia (grade 3: 6%; grade 4: 8%), peripheral neuropathy (grade 3: 8%), fatigue, and bone pain (grade 3: 6% each; grade 4: 2% each) and anaemia (grade 3: 4%). CONCLUSION: The efficacy and tolerability of bortezomib observed in daily practice are consistent with the results obtained in large-scale clinical trials.
