Background: Bone marrow carcinosis is a sign of advanced tumor stage with nonspecific clinical and hematological symptoms. Diagnosis is based on bone marrow biopsy and histopathology, but biopsies are not part of the standard work-up in oncological diseases and data on the correlation between clinical presentation and pathological findings are sparse. Material and methods: In a retrospective single-center study, data from 20 tumor patients with bone marrow carcinosis were analyzed. Bone marrow biopsies were re-evaluated regarding quantity of tumor cells, fibrosis/necrosis, and bone changes. Immunohistochemistry of potential therapy-relevant receptors and PD-L1 was performed. Results: The median age in these 20 patients (13 women, 7 men) was 65 years. The most frequent diagnoses were breast (n = 8) and lung cancer (n = 5). Anemia (94% of patients), thrombocytopenia (72%), and elevated LDH (83%) were frequent findings. The degree of bone marrow infiltration was highly variable and accounted for between 1 and 95% of biopsy space. Significant bone remodeling was present in 14/20 biopsies. No correlation could be found between histological and radiological findings. Treated patients showed some clinical and biochemical improvement, but the overall survival was poor (median 4.5 months, range

The efficacy of bendamustine versus chlorambucil in a phase III trial of previously untreated patients with Binet stage B/C chronic lymphocytic leukaemia (CLL) was re-evaluated after a median observation time of 54 months in May 2010. Overall survival (OS) was analysed for the first time. At follow-up, investigator-assessed complete response (CR) rate (21·0% vs 10·8%), median progression-free survival (21·2 vs 8·8 months; P < 0·0001; hazard ratio 2·83) and time to next treatment (31·7 vs 10·1 months; P < 0·0001) were improved for bendamustine over chlorambucil. OS was not different between groups for all patients or those ≤65 years, >65 years, responders and non-responders. However, patients with objective response or a CR experienced a significantly longer OS than non-responders or those without a CR. Significantly more patients on chlorambucil progressed to second/further lines of treatment compared with those on bendamustine (78·3% vs 63·6%; P = 0·004). The benefits of bendamustine over chlorambucil were achieved without reducing quality of life. In conclusion, bendamustine is significantly more effective than chlorambucil in previously untreated CLL patients, with the achievement of a CR or objective response appearing to prolong OS. Bendamustine should be considered as a preferred first-line option over chlorambucil for CLL patients ineligible for fludarabine, cyclophosphamide and rituximab. © 2012 Blackwell Publishing Ltd.

Data on routine systemic treatment of patients with ovarian cancer are currently available only to a limited degree. The alkylating agent treosulfan is approved in oral (p.o.) and intravenous (i.v.) form for the treatment of ovarian carcinoma. The present non-interventional study analyzed the clinical use of treosulfan in Germany, evaluating the mode of application, toxicity, and response and survival rate.Two hundred and forty-eight ovarian cancer patients in 57 Centers, who received treosulfan mainly either i.v. (5,000-8,000 mg/m(2) d1, q21d or q28d) or p.o. (400-600 mg/m(2) d1-14 or 21, q28d) for at least one therapy cycle were evaluable and were included in the study.With a median age of 70 years (range=36-92 years), predominantly elderly patients received treosulfan treatment. Most participants presented serous histology (131, 52.8%) and advanced-stage FIGO III (122, 49%) or IV (55, 22%) disease. Median ECOG status was 1 (range=0-2), whereas cardiac co-morbidity was common (31%). Treosulfan was usually administered as second- (26%), third- (21%) or fourth-line (17%) therapy. Two hundred and one patients received i.v. and 47 p.o.The most common reason for dose modifications was due to hematological toxicity (46%). The main reason for a therapy discontinuation was progressive disease (38.5%). Response was observed in 25.8% of participants, disease stabilization in 28.6 % and progress in 45.6%. The median progression-free and overall survival was 196 and 405 days, respectively.In predominantly elderly and heavily pre-treated patients with recurrent ovarian cancer, treosulfan featured a clinical relevant efficacy and well-manageable, mostly hematological, toxicity, which resulted in a positive therapeutic index.

Bendamustine demonstrated clinical activity in pre-treated hematological malignancies due to its unique mechanism of action distinct from standard alkylating agents. This study assessed its efficacy in patients with chronic lymphocytic leukemia pre-treated with an alkylator, in comparison to fludarabine. Patients with relapsed chronic lymphocytic leukemia requiring treatment after one previous systemic regimen (usually chlorambucil-based) were randomized to either receive bendamustine 100 mg/m2 on days 1 and 2 of a 4-week cycle or standard fludarabine treatment consisting of 25 mg/m 2 on days 1 to 5 every 4 weeks. The primary objective was to achieve non-inferior progression-free survival (PFS) with bendamustine. Out of a total of 96 patients randomized, 92 were eligible, 49 allocated to bendamustine and 43 to fludarabine. About half of the patients received six or more cycles. Overall response rates were 76 % on bendamustine and 62 % on fludarabine, with clinical complete response rates of 27 and 9 %, respectively. Median PFS was 20.1 and 14.8 months (hazard ratio, 0.87; 90 % confidence interval, 0.60-1.27), median overall survival 43.8 and 41.0 months (hazard ratio, 0.82). Thrombocytopenia and gastrointestinal toxicities were marginally more frequent on bendamustine, albeit CTC grade 3/4 event incidence was similar. These data suggest at least comparable efficacy of bendamustine vs. fludarabine, pointing to an alternative treatment option in relapsing CLL patients after chlorambucil containing initial chemotherapy. © 2013 Springer-Verlag Berlin Heidelberg.

We elucidated the value of tumor-infiltrating lymphocytes (TIL) as an independent predictor for pathologic complete response (pCR) rate and as a prognostic marker for disease-free survival (DFS) in patients with HER2-positive breast cancer in the neoadjuvant setting.We evaluated stromal TILs in 498 HER2-positive breast cancer samples of the neoadjuvant GeparQuattro (G4) and GeparQuinto (G5) trials. Levels of TILs were determined as a continuous parameter per 10% increase and as lymphocyte-predominant breast cancer (LPBC; 60% TILs), and correlated with pCR rate and DFS.In the complete cohort, HER2-positive LPBC cases had a significantly increased pCR rates compared with non-LPBC types. They were significant predictors for pCR in univariate (10% TILs: OR 1.12, P = 0.002; LPBC: OR 2.02, P = 0.002) and multivariate analyses (10% TILs: OR 1.1, P = 0.014; LPBC: OR 1.87, P = 0.009). This effect was also detectable in the trastuzumab-treated (10% TILs: OR 1.12, P = 0.018; LPBC: OR 2.08, P = 0.013) but not in the lapatinib-treated subgroup. We identified a low-risk (pCR/LPBC) and a high-risk group (no pCR/no LPBC) regarding DFS. In triple-positive breast cancer, TILs are of more prognostic relevance than pCR.We could demonstrate the predictive and prognostic impact of TILs in HER2-positive breast cancer in the neoadjuvant setting. In combination with pCR rate, TILs may help to stratify prognostic subgroups, thereby guiding future therapy decisions. Clin Cancer Res; 22(23); 5747-54. 2016 AACR.

A survey was conducted to investigate the standard of care for multiple myeloma in Germany, in order to clarify the status of implementation of international and national treatment guidelines. In addition, the changes in disease management over time were investigated by comparison with surveys conducted in 2008 and 2009. The survey captured a representative sample of 478 myeloma patients with a mean age of 67.9 years across various stages of the disease. Diagnostic approaches, prognostic aspects and treatment decisions were evaluated based on a survey conducted in 2011 in 58 representative centres in Germany, including university and non-university hospitals and office-based haematologists. Data were collected from chart reviews and were analysed retrospectively. Over time, an increasing number of patients were investigated for cytogenetic abnormalities (53%). Age <69 years and lack of comorbid conditions were major determinants for cytogenetic testing. Bortezomib/chemotherapy-based regimens have become the preferred first-line treatments independent of planning autologous blood stem cell transplantation (ASCT) in first-line therapy. Thalidomide- and lenalidomide-based combination therapies are typically used as second-line treatments in 31% of patients. Compared with previous reviews, the frequency of ASCT was stable, at ~30% of patients. Younger age and indicators of more severe disease, such as the presence of CRAB criteria, influenced the decision in favour of performing ASCT. Compared to previous surveys, the requirement for erythropoietin and granulocyte colony-stimulating factor, as well as transfusions of red blood cells and platelets, respectively, have decreased considerably. In summary, novel agents have led to a substantial change in the first-line and relapsed treatment approaches. Age and comorbidities remain major factors influencing treatment decisions, but cytogenetic testing to investigate myeloma-related risk profiles is increasingly integrated. The use of novel agents has affected supportive care, with reduced necessity for substitute blood products and reduced administration of bone marrow-stimulating factors.

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 25 mg/m2 intravenously every 3 wk combined with 5 mg 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 ± 51.5 mg/m2. 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. © 2012 European Association of Urology.

Background: Involuntary weight loss (IWL) is frequent in advanced cancer patients causing compromised anticancer treatment outcomes and function. Cancer cachexia is influenced by nutrition impact symptoms (NIS). The aim of this study was to explore the frequency of NIS in advanced patients and to assess specific interventions guided by a 12-item NIS checklist. Methods: Consecutive patients from an outpatient nutrition-fatigue clinic completed the NIS checklist. The NIS checklist was developed based on literature review and multiprofessional clinical expert consensus. Chart review was performed to detect defined NIS typical interventions. Oncology outpatients not seen in the nutrition-fatigue clinic were matched for age, sex, and tumor to serve as controls. Results: In 52 nutrition-fatigue clinic patients, a mixed cancer population [IWL in 2 months 5. 96 % (mean)], the five most frequent NIS were taste and smell alterations 27 %, constipation 19 %, abdominal pain 14 %, dysphagia 12 %, and epigastric pain 10 %. A statistically significant difference for NIS typical interventions in patients with taste and smell alterations (p = 0. 04), constipation (p = 0. 01), pain (p = 0. 0001), and fatigue (p = 0. 0004) were found compared to the control population [mixed cancer, 3. 53 % IWL in 2 months (mean)]. Conclusion: NIS are common in advanced cancer patients. The NIS checklist can guide therapeutic nutrition-targeted interventions. The awareness for NIS will likely evoke more research in assessment, impact, and treatment. © 2013 Springer-Verlag Berlin Heidelberg.

Various treatment options exist for patients with chronic lymphocytic leukaemia (CLL). Clinical registries provide insight into routine treatment and identify changes in treatment over time. The Tumour Registry Lymphatic Neoplasms prospectively collects data on the treatment of patients with lymphoid B-cell neoplasm as administered by office-based haematologists in Germany. Data on patient and tumour characteristics, co-morbidities, systemic treatments, and outcome parameters are recorded. Eight hundred and six patients with CLL were recruited between May 2009 and August 2013. At the start of first-line treatment, median age was 71years, 64% were male, and 44% had a Binet stage C disease. The most frequently used first-line/second-line regimens were bendamustine+rituximab (BR, 56%/55%), fludarabine+cyclophosphamide+rituximab (FCR, 22%/11%), and bendamustine (B, 5%/9%). Chlorambucil was used in only 7% (first-line) and 6% (second-line) of patients. Patients treated with FCR were younger and healthier than patients treated with BR. Overall, 91% of first-line treatments were successful (40% complete response). Real-life patient populations differ considerably from patients treated in randomized controlled trials. BR and FCR dominate the first-line and second-line treatments of CLL by office-based haematologists in Germany. Future analysis will investigate progression-free and overall survival times.

Monoclonal antibodies against the PD-1 receptor or its ligands result in a recovery of T cell responses against tumor antigens. Nivolumab is the first antibody that has been approved in lung cancer. This mode of action is very intersting, especially because of long term responses and the moderate toxicity.
