Patients with indolent lymphomas are at high risk of infections: experience from a German outpatient clinic.

BACKGROUND: Patients with indolent B-cell non-Hodgkin lymphomas (B-NHLs) have an increased risk of infections which is caused by pathomechanisms of the diseases itself but also as a result of anti-tumor therapy. Especially the effects of anti-CD20 antibodies are well understood as these lead to decreased antibody production. Most studies regarding immunodeficiency in B-NHLs were conducted with multiple myeloma and chronic lymphocytic leukemia patients. As these studies not always represent the general population we collected and analyzed real world data from patients with indolent lymphomas and a control group (CG). RESULTS: Patients with B-NHLs undergoing therapy or who were regularly monitored in a watch and wait approach had, over the time of one year, an increased rate of infections compared to the CG of 145 healthy volunteers (mean: 11.66 vs. 7.13 infections per 1000 days). Consistent with this finding B-NHL patients received more antibiotic treatment (mean: 11.17 vs. 6.27 days) and were more often hospitalized than persons from the CG (mean: 5.19 vs. 0.99 days per 1000 days). Lymphoma patients without immunodeficiency had a lower infection rate than patients with non-symptomatic and symptomatic immunodeficiency (mean: 10.91 vs. 12.07 and 12.36 per 1000 days). The number of infections differed statistically significant for the subgroups and CG (7.13 per 1000 days). Patients with symptomatic immunodeficiency were mostly treated with regular immunoglobulin substitutions and infection rates were comparable to those of patients with asymptomatic immunodeficiency. CONCLUSIONS: Our data suggest the use of an approach with regular immune monitoring including the measurement of immunoglobulin levels and regular appointments for clinical assessment of all indolent lymphoma patients in order to identify patients with increased risk of infections. It also raises the question if patients with immunodeficiency should be treated more often with regular immunoglobulin substitution, but so far more studies are necessary to answer this question.

Imatinib dose reduction in major molecular response of chronic myeloid leukemia: results from the German Chronic Myeloid Leukemia-Study IV.

Standard first-line therapy of chronic myeloid leukemia is treatment with imatinib. In the randomized German Chronic Myeloid Leukemia-Study IV, more potent BCR-ABL inhibition with 800 mg ('high-dose') imatinib accelerated achievement of a deep molecular remission. However, whether and when a de-escalation of the dose intensity under high-dose imatinib can be safely performed without increasing the risk of losing deep molecular response is unknown. To gain insights into this clinically relevant question, we analyzed the outcome of imatinib dose reductions from 800 mg to 400 mg daily in the Chronic Myeloid Leukemia-Study IV. Of the 422 patients that were randomized to the 800 mg arm, 68 reduced imatinib to 400 mg after they had achieved at least a stable major molecular response. Of these 68 patients, 61 (90%) maintained major molecular remission on imatinib at 400 mg. Five of the seven patients who lost major molecular remission on the imatinib standard dose regained major molecular remission while still on 400 mg imatinib. Only two of 68 patients had to switch to more potent kinase inhibition to regain major molecular remission. Importantly, the lengths of the intervals between imatinib high-dose treatment before and after achieving major molecular remission were associated with the probabilities of maintaining major molecular remission with the standard dose of imatinib. Taken together, the data support the view that a deep molecular remission achieved with high-dose imatinib can be safely maintained with standard dose in most patients.

Elotuzumab, lenalidomide, bortezomib, dexamethasone, and autologous haematopoietic stem-cell transplantation for newly diagnosed multiple myeloma (GMMG-HD6): results from a randomised, phase 3 trial.

BACKGROUND: The aim of this trial was to investigate the addition of the anti-SLAMF7 monoclonal antibody elotuzumab to lenalidomide, bortezomib, and dexamethasone (RVd) in induction and consolidation therapy as well as to lenalidomide maintenance treatment in transplant-eligible patients with newly diagnosed multiple myeloma. METHODS: GMMG-HD6 was a phase 3, randomised trial conducted at 43 main trial sites and 26 associated trial sites throughout Germany. Adult patients (aged 18-70 years) with previously untreated, symptomatic multiple myeloma, and a WHO performance status of 0-3, with 3 being allowed only if caused by myeloma disease and not by comorbid conditions, were randomly assigned 1:1:1:1 to four treatment groups. Induction therapy consisted of four 21-day cycles of RVd (lenalidomide 25 mg orally on days 1-14; bortezomib 1·3 mg/m2 subcutaneously on days 1, 4, 8, and 11]; and dexamethasone 20 mg orally on days 1, 2, 4, 5, 8, 9, 11, 12, and 15 for cycles 1-2) or, RVd induction plus elotuzumab (10 mg/kg intravenously on days 1, 8, and 15 for cycles 1-2, and on days 1 and 11 for cycles 3-4; E-RVd). Autologous haematopoietic stem-cell transplantation was followed by two 21-day cycles of either RVd consolidation (lenalidomide 25 mg orally on days 1-14; bortezomib 1·3 mg/m2 subcutaneously on days 1, 8, and 15; and dexamethasone 20 mg orally on days 1, 2, 8, 9, 15, and 16) or elotuzumab plus RVd consolidation (with elotuzumab 10 mg/kg intravenously on days 1, 8, and 15) followed by maintenance with either lenalidomide (10 mg orally on days 1-28 for cycles 1-3; thereafter, up to 15 mg orally on days 1-28; RVd/R or E-RVd/R group) or lenalidomide plus elotuzumab (10 mg/kg intravenously on days 1 and 15 for cycles 1-6, and on day 1 for cycles 7-26; RVd/E-R or E-RVd/E-R group) for 2 years. The primary endpoint was progression-free survival analysed in a modified intention-to-treat (ITT) population. Safety was analysed in all patients who received at least one dose of trial medication. This trial is registered with ClinicalTrials.gov, NCT02495922, and is completed. FINDINGS: Between June 29, 2015, and on Sept 11, 2017, 564 patients were included in the trial. The modified ITT population comprised 559 (243 [43%] females and 316 [57%] males) patients and the safety population 555 patients. After a median follow-up of 49·8 months (IQR 43·7-55·5), there was no difference in progression-free survival between the four treatment groups (adjusted log-rank p value, p=0·86), and 3-year progression-free survival rates were 69% (95% CI 61-77), 69% (61-76), 66% (58-74), and 67% (59-75) for patients treated with RVd/R, RVd/E-R, E-RVd/R, and E-RVd/E-R, respectively. Infections (grade 3 or worse) were the most frequently observed adverse event in all treatment groups (28 [20%] of 137 for RVd/R; 32 [23%] of 138 for RVd/E-R; 35 [25%] of 138 for E-RVd/R; and 48 [34%] of 142 for E-RVd/E-R). Serious adverse events (grade 3 or worse) were observed in 68 (48%) of 142 participants in the E-RVd/E-R group, 53 (39%) of 137 in the RVd/R, 53 (38%) of 138 in the RVd/E-R, and 50 (36%) of 138 in the E-RVd/R (36%) group. There were nine treatment-related deaths during the study. Two deaths (one sepsis and one toxic colitis) in the RVd/R group were considered lenalidomide-related. One death in the RVd/E-R group due to meningoencephalitis was considered lenalidomide and elotuzumab-related. Four deaths (one pulmonary embolism, one septic shock, one atypical pneumonia, and one cardiovascular failure) in the E-RVd/R group and two deaths (one sepsis and one pneumonia and pulmonary fibrosis) in the E-RVd/E-R group were considered related to lenalidomide or elotuzumab, or both. INTERPRETATION: Addition of elotuzumab to RVd induction or consolidation and lenalidomide maintenance in patients with transplant-eligible newly diagnosed multiple myeloma did not provide clinical benefit. Elotuzumab-containing therapies might be reserved for patients with relapsed or refractory multiple myeloma. FUNDING: Bristol Myers Squibb/Celgene and Chugai.

Curricular course for medical students at a hematology and oncology specialty practice, 2010-2022.

Aim: For several years now, medical students have also been taught general practice at academic medical teaching practices. Specialty practices have not yet been included in the curricular education. Since 1998, we have conducted a block seminar in hematology twice per semester for eighth-semester medical students. This block seminar was offered from 1998-2001 to students at the Philipps University in Marburg and since 2001 to students at the Johannes Gutenberg University in Mainz. Since 2010 our block seminar has been part of the curriculum at the Johannes Gutenberg University. Method: Standardized course evaluation by students who had attended our block seminar between January 2010 and March 2022. Courses that were held virtually due to corona were not included in the analysis. The questionnaire used to evaluate courses in the medical degree program at the Johannes Gutenberg University served as the evaluation instrument. Results: Since 1998 more than 1,000 students have attended our seminar. The systematic evaluation of the course by 500 students who participated in the curricular, classroom-based seminar sessions since 2010 shows that the highest ratings possible are given for practical relevance, learning atmosphere, teaching and effectiveness. Conclusion: High quality in teaching curricular courses to medical students at a specialty practice is possible. Insights into the possibilities connected with working in the outpatient setting at a medical practice broadens students' experience. This teaching format facilitates external university instructors in terms of teaching and, at the same time, relieves the university in terms of staff and financial budget.

Pathological Response in the Breast and Axillary Lymph Nodes after Neoadjuvant Systemic Treatment in Patients with Initially Node-Positive Breast Cancer Correlates with Disease Free Survival: An Exploratory Analysis of the GeparOcto Trial.

BACKGROUND: The conversion of initially histologically confirmed axillary lymph node-positive (pN+) to ypN0 after neoadjuvant systemic treatment (NAST) is an important prognostic factor in breast cancer (BC) patients and may influence surgical de-escalation strategies. We aimed to determine pCR rates in lymph nodes (pCR-LN), the breast (pCR-B), and both (tpCR) in women who present with pN+ BC, to assess predictors for response and the impact of pCR-LN, pCR-B, and tpCR on invasive disease-free survival (iDFS). METHODS: Retrospective, exploratory analysis of 242 patients with pN+ at diagnosis from the multicentric, randomized GeparOcto trial. RESULTS: Of 242 patients with initially pN+ disease, 134 (55.4%) had a pCR-LN, and 109 (45.0%) a pCR-B. Of the 109 pCR-B patients, 9 (8.3%) patients had involved LN, and 100 (41.3%) patients had tpCR. Those with involved LN still had a bad prognosis. As expected, pCR-B and intrinsic subtypes (TNBC and HER2+) were identified as independent predictors of pCR-LN. pCR-LN (ypN0; hazard ratio 0.42; 95%, CI 0.23-0.75; p = 0.0028 for iDFS) was the strongest independent prognostic factor. CONCLUSIONS: In initially pN+ patients undergoing NAST, the conversion to ypN0 is of high prognostic value. Surgical axillary staging after NAST is still essential in these patients to offer tailored treatment.

Addition of isatuximab to lenalidomide, bortezomib, and dexamethasone as induction therapy for newly diagnosed, transplantation-eligible patients with multiple myeloma (GMMG-HD7): part 1 of an open-label, multicentre, randomised, active-controlled, phase 3 trial.

BACKGROUND: Anti-CD38 monoclonal antibodies have consistently shown increased efficacy when added to standard of care for patients with multiple myeloma. We aimed to assess the efficacy of isatuximab in addition to lenalidomide, bortezomib, and dexamethasone in patients with newly diagnosed transplantation-eligible multiple myeloma. METHODS: This open-label, multicentre, randomised, active-controlled, phase 3 trial was done at 67 academic and oncology practice centres in Germany. This study is ongoing and divided into two parts; herein, we report results from part 1. Eligible patients were aged 18-70 years; had a confirmed diagnosis of untreated multiple myeloma requiring systemic treatment and a WHO performance status of 0-2; and were eligible for induction therapy, high-dose melphalan and autologous haematopoietic stem-cell transplantation, and maintenance treatment. Patients were randomly assigned (1:1) to receive three 42-day cycles of induction therapy either with isatuximab plus lenalidomide, bortezomib, and dexamethasone (isatuximab group) or lenalidomide, bortezomib, and dexamethasone alone (control group) using a web-based system and permuted blocks. Patients in both groups received lenalidomide (25 mg orally on days 1-14 and 22-35), bortezomib (1·3 mg/m2 subcutaneously on days 1, 4, 8, 11, 22, 25, 29, and 32), and dexamethasone (20 mg orally on days 1-2, 4-5, 8-9, 11-12, 15, 22-23, 25-26, 29-30, and 32-33). Isatuximab was given as 10 mg/kg intravenously on days 1, 8, 15, 22, and 29 of cycle 1 and on days 1, 15, and 29 of cycles 2 and 3. The primary endpoint was minimal residual disease (MRD) negativity assessed by flow cytometry, in the intention-to-treat (ITT) population. This study is registered with ClinicalTrials.gov, NCT03617731. FINDINGS: Between Oct 23, 2018, and Sep 22, 2020, 660 patients were included in the ITT analysis (331 in the isatuximab group and 329 in the control group). 654 (99%) patients were White, two were African, one was Arabic, and three were Asian. 250 (38%) were women and 410 (62%) were men. The median age was 59 years (IQR 54-64). MRD negativity after induction therapy was reached in 166 (50%) patients in the isatuximab group versus 117 (36%) in the control group (OR 1·82 [95% CI 1·33-2·48]; p=0·00017). Median follow-up time from start to end of induction therapy was 125 days (IQR 125-131) versus 125 days (125-132). At least one grade 3 or 4 adverse event occurred in 208 (63%) of 330 patients versus 199 (61%) of 328 patients. Neutropenia of grade 3 or 4 occurred in 77 (23%) versus 23 (7%) patients and infections of grade 3 or 4 occurred in 40 (12%) versus 32 (10%) patients. Among 12 deaths during induction therapy, one death due to septic shock in the isatuximab group and four deaths (one cardiac decompensation, one hepatic and renal failure, one cardiac arrest, and one drug-induced enteritis) in the control group were considered treatment-related. INTERPRETATION: Addition of isatuximab to lenalidomide, bortezomib, and dexamethasone for induction therapy improved rates of MRD negativity with no new safety signals in patients with newly diagnosed transplantation-eligible multiple myeloma.

Survival improvement of patients with chronic lymphocytic leukemia (CLL) in routine care 1995-2017.

Seven hundred and twenty-four CLL-outpatients with a median age of 67 (35-92) were analyzed. Four hundred and twenty-seven (59%) were male, 297 (41%) female. At diagnosis 556 (77%) were in Binet stage A, 91 (13%) stage B and 36 (5%) stage C. Forty-six percent received treatment during the evaluation period. Treatment consisted of purine analogs in 38%, alkylating agents in 96%, chemoimmunotherapy with anti-CD20 monoclonal antibodies in 63%, ibrutinib in 9%, venetoclax in 1% and idelalisib in 3%. 3% received allogeneic hematopoietic stem cell transplantation. Overall survival (OS) according to Binet stage was: A 13.9 years (0.1-37.4), B 9.2 years (1.4-29.3) and C 7.9 years (0.5-19.4) respectively. Median OS from the start of therapy improved over time; 1995-2001: 5.8 years, 2002-2008: 6.1 years and 2009-2017: median not reached. Survival of patients with CLL has improved in routine care and was strongly related to active disease, disease stage, performance status and whether therapy included an anti-CD20 monoclonal antibody.

Differential effect on different immune subsets of neoadjuvant chemotherapy in patients with TNBC.

BACKGROUND: Triple-negative breast cancer (TNBC) is the most aggressive form of breast cancer (BC). Due to the absence of targets such as HER2 or hormone receptors, early TNBC is treated with surgery and chemotherapy. Since TNBC is also considered the most immunogenic type of BC with tumor infiltrating lymphocytes that are predictive for chemotherapy response and prognostic for patients' survival, many different immunotherapeutic strategies are currently explored in clinical trials for the treatment of this disease. In order to efficiently combine chemotherapy with immunotherapy, it is important to evaluate the effect of chemotherapy on immune cells in vivo. METHODS: Peripheral blood was taken from 56 patients with TNBC undergoing neoadjuvant chemotherapy with nanoparticle albumin-bound paclitaxel (Nab-Pac) followed by epirubicin and cyclophosphamide (EC) at three different time points. Multicolor flow cytometry was used to characterize the immune cell composition and functional properties along neoadjuvant chemotherapy. RESULTS: Whereas the first phase of the neoadjuvant chemotherapy did not significantly alter the patients' immune cell composition, after the second phase of chemotherapeutic administration most B cells (>90%) were lost and the frequency of natural killer (NK) cells and CD4+ T lymphocytes decreased approximately to 50%. In contrast, the frequency of CD8+ T cells were less affected. CONCLUSIONS: Despite late consequences of Nab-Pac cannot be ruled out, these data suggest that different chemotherapeutics might have distinct effects on the immune cell repertoire and that different immune cell populations exhibit a specific susceptibility to these chemotherapies with B and NK cells being more affected than T cells. This might also have an impact on the combination of chemotherapies with immunotherapies. TRIAL REGISTRATION NUMBER: NCT02685059.

Improved survival of patients with metastatic breast cancer in routine care: results of a retrospective study in a community-based oncology group practice 1995-2005.

BACKGROUND: Little is known about the treatment reality in metastatic breast cancer (MBC) outside clinical trials. We undertook this analysis to evaluate the actual treatment reality for unselected patients with MBC in routine care. PATIENTS AND METHODS: All patients with MBC, who were treated in our community-based group practice between 1995 and 2005, were analyzed retrospectively concerning prognostic factors, treatment, and survival. RESULTS: 403 consecutive patients were evaluated with a median age of 60 years (range 32-93). Aromatase inhibitor therapy was used in 87% of all patients. 83% received chemotherapy with the median number of lines being 3 (1-15). An anthracycline was given to 49%, a taxane was used in 55%, vinorelbine in 42%, capecitabine in 36%, gemcitabine in 28%, and a platinum compound in 9%. 94% of patients with bone metastasis received a bisphosphonate, and 63% of HER-2/neu-positive patients were treated with trastuzumab. Median survival since the start of palliative therapy was 30 months. Statistical analysis revealed as major prognostic factors hormone receptor status and prevalence of only bone metastasis. CONCLUSIONS: Treatment reality of MBC in routine care reveals a prolonged median survival of 30 months which is probably due to the sequential use of the most effective treatment modalities.

Intense dose-dense epirubicin, paclitaxel, cyclophosphamide versus weekly paclitaxel, liposomal doxorubicin (plus carboplatin in triple-negative breast cancer) for neoadjuvant treatment of high-risk early breast cancer (GeparOcto-GBG 84): A randomised phase III trial.

BACKGROUND: GeparOcto compared efficacy and safety of two chemotherapy regimens in high-risk early breast cancer (BC): sequential treatment with intense dose-dense epirubicin, paclitaxel, and cyclophosphamide (iddEPC) and weekly treatment with paclitaxel plus non-pegylated liposomal doxorubicin (M, Myocet®) with additional carboplatin (PM(Cb)) in triple-negative BC (TNBC). PATIENTS AND METHODS: Patients with cT1c-cT4a-d and centrally assessed human epidermal growth factor receptor (HER)2-positive BC or TNBC were eligible, irrespective of nodal status, luminal B-like tumours only if pN+. Patients were randomised (stratified by BC subtype, Ki67, lymphocyte-predominant BC) to receive 18 weeks of E (150 mg/m2) followed by P (225 mg/m2) followed by C (2000 mg/m2), each q2w for 3 cycles or weekly P (80 mg/m2) plus M (20 mg/m2) plus, in TNBC, Cb (area under curve (AUC) 1.5). HER2-positive BC patients additionally received trastuzumab (6 [loading dose 8]mg/kg q3w) and pertuzumab (420 [840]mg q3w) with all P and C cycles. Primary end-point was pathological complete response (pCR, ypT0/is ypN0), secondary end-points included other pCR definitions, pCR in stratified subpopulations, tolerability and compliance. This trial is registered with ClinicalTrials.gov number NCT02125344. RESULTS: 945/961 randomised patients started treatment. The median age was 48 years; 7.6% had cT3-4, 46% cN+, 66% G3, 40% HER2-positive, 43% TNBC. pCR rate with iddEPC was 48.3%, with PM(Cb) 48.0%, respectively (PM(Cb) versus iddEPC odds ratio 0.99; 95% confidence interval 0.77-1.28, P = 0.979) with no significant differences observed in TNBC, HER2-positive, luminal B-like subtypes. 16.4% with iddEPC and 34.1% with PM(Cb) discontinued treatment (P < 0.001), mainly due to adverse events; two patients on PM(Cb) died. CONCLUSIONS: In high-risk early BC there is no difference in pCR rates following neoadjuvant treatment with iddEPC or weekly PM(Cb), respectively. iddEPC is one of the effective dose-dense regimens feasible in daily practice.

High anti-lymphoma activity of bendamustine/mitoxantrone/rituximab in rituximab pretreated relapsed or refractory indolent lymphomas and mantle cell lymphomas. A multicenter phase II study of the German Low Grade Lymphoma Study Group (GLSG).

On the basis of a preceding phase I study, the current trial explored bendamustine in combination with mitoxantrone and rituximab (BMR) in patients with stage III/IV relapsed or refractory indolent lymphomas and mantle cell lymphoma (MCL) with or without prior rituximab containing chemo-immunotherapy (R-chemo) treatment. Therapy consisted of bendamustine 90 mg/m(2) days 1 + 2, mitoxantrone 10 mg/m(2) day 1, rituximab 375 mg/m(2) day 8. Treatment was repeated on day 29 for a total of four cycles. Between 3 April and 04 July, 57 patients were recruited from 24 participating institutions, 39% of whom had received prior R-chemo therapy. Median age was 66 years (40 - 83). Lymphoma subtypes were 29 follicular (FL), 18 MCL, and 10 other indolent lymphomas. The overall response rate (ORR) was 89% with 35% CR and 54% PR. ORR in R-chemo pretreated patients was 76% (38% CR, 38% PR). After a median observation time of 27 months (1 - 43), the estimated median progression free survival is 19 months. The 2 year overall survival is 60% for patients with FL and MCL. Treatment related toxicities of grade 3/4 comprised a reversible myelosuppression (10% anemia, 78% leukocytopenia, 46% granulocytopenia, 16% thrombocytopenia). However, unexpected hospitalisations were necessary after 4% of BMR-application only. BMR is a very effective new outpatient immuno-chemotherapy with low toxicity for patients with relapsed/refractory FL, MCL and other indolent lymphomas.

Ovarian cancer treatment reality in northern Rheinland-Pfalz (Germany). Suboptimal surgical treatment as a possible cause for inferior survival.

BACKGROUND: With regard to incidence, ovarian cancer has the highest mortality of all gynecologic cancers. PATIENTS AND METHODS: The treatment of 139 consecutive patients with epithelial ovarian cancer who were treated in an oncology group practice in Koblenz, Germany between 1995 and 2003 was evaluated retrospectively. RESULTS: The median age of the patients was 61 years (18-84). FIGO stages were distributed as follows: stage I 15.8%, stage II 12.9%, stage III 53.2%, stage IV 16.5%. 49 patients (35.5%) received surgical treatment at a university hospital or a teaching hospital. 89 patients (64.5%) were operated on in a local or district hospital. A macroscopically complete resection was achieved in only 15 patients (10.8%). The residual tumor was <1 cm in 50 patients (36%), >1 cm in 24 patients (17.3%), and >2 cm in 49 patients (35.5%). 93.3% of the patients received postoperative, platinum-based chemotherapy. Median survival since first diagnosis was 42 months (1-346(+)). The 5-year survival rate of the whole cohort was only 28%. CONCLUSIONS: Overall survival in epithelial ovarian cancer was significantly inferior in this patient cohort compared to the results of the FIGO report from 2003. One possible cause may be the suboptimal surgical treatment, with 52.8% of the patients having a postoperative residual tumor larger than 1 cm.

Outpatient Management of Patients with Immune Thrombocytopenia (ITP) by Hematologists 1995-2014.

BACKGROUND: The aim of this study was to evaluate the treatment reality for outpatients with immune thrombocytopenia (ITP) managed by hematologists in routine care. PATIENTS AND METHODS: All patients with ITP diagnosed between 06/1995 and 12/2014 in a community-based oncology group practice in Germany were retrospectively analyzed. RESULTS: 422 patients with a median age of 55 years (range 7-91 years) were evaluated. 57% were female and 43% male. Only 198 (47%) patients needed therapy. First-line therapy (n = 198) consisted of steroids in 81%, intravenous immunoglobulins (IVIG) in 12%, and IVIG plus steroids in 6%. Patients received a median of 2 (range 1-10) lines of therapy. The most frequently used treatment modalities were steroids in 93%, IVIG in 55%, splenectomy in 21%, and other immunosuppressive agents (OISA) in 23% of patients. Rituximab and thrombopoietin receptor agonists (TRAs) were used in 10% and 6% only. 9 (2%) patients needed hospitalization due to bleeding complications. 72% of patients achieved a durable remission after their last line of therapy. 1 (0.2%) patient died due to bleeding complications. CONCLUSION: The treatment modalities most frequently used are steroids, immunoglobulins, splenectomy, and OISA. Rituximab and TRAs are only used infrequently. 72% of ITP patients achieve durable remissions. The rate of hospital admissions due to bleeding complications and the ITP-related mortality are low. The majority of ITP patients can be safely managed by hematologists on an outpatient basis.

Adherence assessment of patients with metastatic solid tumors who are treated in an oncology group practice.

Due to the increase of oral agents nonadherence is an emerging challenge in cancer care. We evaluated how well different assessments match and how adherence could be measured in routine care. For this purpose patients suffering from metastatic solid tumors who were treated with oral anticancer drugs in an oncology group practice were surveyed. Attending oncologists answered a questionnaire, too, and a retrospective analysis of prescription data was conducted. Caregivers who were eligible for an interview were surveyed additionally. 128 patients (70 % female) with a median age of 69 years (36-88) took part, 95 % of all approached patients. 56 % suffered from metastatic breast cancer, 44 % from other metastatic solid tumors. 65 caregivers (60 % female) with a median age of 62 years (21-82) were interviewed as well. Patients were assessed in 84 % as very reliable in medication-taking by their oncologists. This high adherence rate was supported by patients, caregivers and prescription data. However, concordance between assessments of patients, caregivers and oncologists was not substantial. Our method of considering different perspectives to assess adherence has to be improved and validated but could help to evaluate adherence with oral cancer therapy in routine care.

Metastatic breast cancer: prolongation of survival in routine care is restricted to hormone-receptor- and Her2-positive tumors.

18,000 women die due to metastatic breast cancer in Germany per year. Median survival is 20-28 months after diagnosis. The question we wanted to answer was whether survival has improved in routine care? For this purpose we conducted a retrospective analysis of all patients with metastatic breast cancer who were treated between 06/1995-06/2013 in a community-based oncology group practice in Germany. 716 patients were analyzed with a median age of 61 (31-93). Localizations of metastases were distributed as follows: 47% visceral, 36% bone, 9% lymphatic, 4% CNS, 4% others. 79% were hormone-receptor-positive, 20% Her2-positive, 9% triple-negative. Median overall survival was 34 months (95% Confidence Interval: 31-37), median disease-specific survival 36.8 months and disease-specific survival after 5 years 34%. Survival was significantly correlated with localizations of metastases, number of metastasized organs, disease free survival since initial diagnosis, hormone-receptor status and age. Patients with hormone-receptor-positive tumors had a median overall survival of 37 months, Her2-positive patients of 34 months and triple-negative patients of 13 months. 86% of hormone-receptor-positive patients received antihormonal therapy. 81% of Her2-positive patients received anti-Her2 therapy. In summary, longer survival is strongly restricted to hormone receptor- and Her2-positive tumors most likely due to targeted therapies directed against the estrogen-receptor and Her2.

Breast cancer morbidity: questionnaire survey of patients on the long term effects of disease and adjuvant therapy.

BACKGROUND: Many women have symptoms of various kinds after being treated for breast cancer. It is unclear how frequently these different side effects of treatment arise. METHOD: All women who underwent surgery for breast cancer and subsequently received adjuvant systemic treatment in a single certified breast-cancer center from 2006 to 2010 were asked to fill out a standardized questionnaire. Medical data were retrieved from their charts and statistically analyzed together with the questionnaire responses. The questionnaire was also given to an age-adjusted control group. RESULTS: 734 questionnaires were filled out and returned (response rate, 70%). The mean interval from the diagnosis of breast cancer to the time of response to the questionnaire was 38 months. The median age at time of response to the questionnaire was 65 years (range, 30 to 91 years). The distribution of UICC stages at the time of initial diagnosis was as follows: I 46%, II 42%, III 12%. 78% of the patients underwent breat conserving surgery, 85% had radio - therapy, 85% had antihormonal treatment, and 49% had chemotherapy. 91% were satisfied or very satisfied with the outcome of surgery. 34% reported operation site pain; 35% reported limitations of shoulder or arm function. Younger patients suffered from emotional sequelae more than older ones did. 25% reported a change in their relationship with their spouse. Before being diagnosed with breast cancer, 9% had consulted a psychiatrist or psychotherapist; after the diagnosis, 19% did. 14% had taken psychoactive medication before the diagnosis, and 26% did afterward. CONCLUSION: Treatment for breast cancer has negative physical, emotional, and social effects on many patients. They suffer these effects to varying degrees depending on age, type of surgery, and systemic treatment.

Retreatment with bendamustine-containing regimens in patients with relapsed/refractory chronic lymphocytic leukemia and indolent B-cell lymphomas achieves high response rates and some long lasting remissions.

Bendamustine and bendamustine/rituximab combinations have shown high efficacy in relapsed/refractory chronic lymphocytic leukemia (CLL) and indolent B-cell malignancies (non-Hodgkin lymphoma, NHL). No data exist about bendamustine retreatment after relapse, concerning efficacy and toxicity in this patient population. Eighty-eight outpatients (57 patients with CLL, 31 patients with NHL) who had previously been treated with bendamustine were retreated with a bendamustine regimen. Treatment consisted of bendamustine (B) or bendamustine + mitoxantrone (BM) or bendamustine + rituximab (BR) or bendamustine + mitoxantrone + rituximab (BMR). Median age was 72 years (50-88). A reversible grade 3 or 4 leukocytopenia or thrombocytopenia was observed in 24% and 13%, respectively. The overall response rate (ORR) was 76% (7% complete remission [CR], 69% partial remission [PR]) with 77% (6% CR, 71% PR) in CLL and 71% (8% CR, 63% PR) in NHL. ORR according to regimen was as follows: B: 57% (14% CR, 43% PR), BM: 70% (4% CR, 66% PR), BR: 55% (10% CR, 45% PR), BMR: 84% (7% CR, 78% PR). Bendamustine retreatment is feasible and achieves high response rates and some long lasting remissions.

Bendamustine/mitoxantrone/rituximab: a short remission induction chemoimmunotherapy for elderly patients with relapsed or refractory chronic lymphocytic leukemia.

We have evaluated all outpatients with relapsed or refractory chronic lymphocytic leukemia (CLL) who were treated with bendamustine/mitoxantrone/rituximab (BMR) between May 1999 and December 2008. Treatment consisted of bendamustine 90 mg/m2 on day 1 + 2, Mitoxantrone 6 mg/m2 on day 1, and Rituximab 375 mg/m2 on day 8, 15, 22 + 29. Thirty-nine patients (19 males, 20 females) received BMR with a median age of 69 years (46­81). Nineteen patients (49%) were above 70 years and 13 patients (33%) were 75 years or above. Performance score ranged between 0 and 2. The median number of previous therapies was 2 (1­4). Therapy was tolerated well with two observed therapy-associated hospitalizations. A reversible grade 3 or 4 hematotoxicity was seen in 30 patients (77%). Other reversible grade 3 or 4 toxicities were seen in two patients (5%). The overall response rate was 92% (10% complete remission, 82% partial remission). Median time to next CLL-therapy was 13 months (0­69). We conclude that BMR is a short and effective outpatient chemoimmunotherapy for patients with relapsed or refractory CLL, which can be used safely in elderly patients.
