Molecular Long-Term Analysis of the GMMG-HD4 Trial in Multiple Myeloma-Patterns of Association of Chromosomal Aberrations with Response and Proliferation Determining Survival in Selecting Treatments in View of Limited Resources in Low- and Middle-Income Countries.

Based on the lack of differences in progression-free and overall survival after a median follow-up of 93 months in our HOVON-65/GMMG-HD4 trial (German part; = 395) randomizing VAD induction (vincristin/adriamycin/dexamthasone)/tandem-transplantation/thalidomide-maintenance vs. PAD induction (bortezomib/adriamycin/dexamethasone)/tandem transplantation/bortezomib maintenance, we discern how chromosomal aberrations determine long-term prognosis by different patterns of association with proliferation and treatment-dependent response, whether responses achieved by different regimens are equal regarding prognosis, and whether subpopulations of patients could be defined as treatable without upfront "novel agents" in cases of limited resources, e.g.

Older patients with EGFR mutation-positive non-small cell lung cancer treated with afatinib in clinical practice: A subset analysis of the non-interventional GIDEON study.

Introduction: Lung cancer is most common in older patients; despite this, older patients are historically under-represented in clinical studies. Here we present data from GIDEON, a study undertaken in Germany in patients with epidermal growth factor receptor mutation-positive (EGFRm+) non-small cell lung cancer (NSCLC) receiving first-line afatinib. GIDEON enrolled a high proportion of patients aged ≥70 years, providing an opportunity to study afatinib use in older patients.

Lenalidomide versus bortezomib maintenance after frontline autologous stem cell transplantation for multiple myeloma.

Lenalidomide (LEN) maintenance (MT) post autologous stem cell transplantation (ASCT) is standard of care in newly diagnosed multiple myeloma (MM) but has not been compared to other agents in clinical trials. We retrospectively compared bortezomib (BTZ; n = 138) or LEN (n = 183) MT from two subsequent GMMG phase III trials. All patients received three cycles of BTZ-based triplet induction and post-ASCT MT.

Prognostic significance of cytogenetic heterogeneity in patients with newly diagnosed multiple myeloma.

We investigated subclonal cytogenetic aberrations (CA) detected by interphase fluorescence in situ hybridization (iFISH) in patients with newly diagnosed multiple myeloma (MM) enrolled in the Haemato Oncology Foundation for Adults in the Netherlands (HOVON)-65/German-Speaking MM Group (GMMG)-HD4 phase 3 trial. Patients were either treated with 3 cycles of vincristine, Adriamycin, and dexamethasone or bortezomib, Adriamycin, and dexamethasone and then thalidomide or bortezomib maintenance after tandem autologous transplantation. Subclones were defined either by presence of different copy numbers of the same chromosome loci and/or CA present in at least 30% less and maximally 2/3 of cells compared with the main clone CA.

AIO LQ-0110: a randomized phase II trial comparing oral doxycycline versus local administration of erythromycin as preemptive treatment strategies of panitumumab-mediated skin toxicity in patients with metastatic colorectal cancer.

Background: Dermatologic toxicities, especially akne-like skin rash, are the most common side-effects associated with anti-epidermal growth factor receptor (EGFR) therapy. Preemptive treatment with oral tetracyclines is recommended as a standard. Topical prophylactic options have thus far not been compared to tetracyclines.

Single versus tandem high-dose melphalan followed by autologous blood stem cell transplantation in multiple myeloma: long-term results from the phase III GMMG-HD2 trial.

The prospective, randomized phase III trial GMMG-HD2 aimed at demonstrating non-inferiority of single (Arm A) versus tandem (Arm B) high-dose melphalan followed by autologous transplantation (HDM/ASCT) with regard to 2-year event-free survival (EFS) in newly-diagnosed multiple myeloma (MM) and included 358 evaluable patients [Intention-to-treat population, (ITT), single/tandem HDM/ASCT: n = 177/181]. After a median follow-up of more than 11 years, non-inferiority of single versus tandem HDM/ASCT was demonstrated using the planned non-inferiority threshold of 15% of the 2-year EFS rate. Neither EFS (P = 0·53) nor overall survival (OS) (P = 0·33) differences were observed in the ITT population.

Secondary malignancies in chronic myeloid leukemia patients after imatinib-based treatment: long-term observation in CML Study IV.

Treatment of chronic myeloid leukemia (CML) has been profoundly improved by the introduction of tyrosine kinase inhibitors (TKIs). Long-term survival with imatinib is excellent with a 8-year survival rate of ∼88%. Long-term toxicity of TKI treatment, especially carcinogenicity, has become a concern.

Rituximab maintenance improves survival in male patients with diffuse large B-cell lymphoma. Results of the HD2002 prospective multicentre randomized phase III trial.

In the multicentre prospective randomized HD2002 trial, rituximab maintenance therapy (375 mg/m(2) every 3 months for 2 years) versus observation was evaluated for CD20(+) B-cell lymphoma. Out of 321 patients [161 randomized to the treatment group (TG), 160 to the observation group (OG)], 295 data sets were evaluable for statistical analysis. Estimated 5-year relapse-free survival (RFS) was 81% in the TG and 70% in the OG (logrank test, P = 0·047).

Phase III trial of bortezomib, cyclophosphamide and dexamethasone (VCD) versus bortezomib, doxorubicin and dexamethasone (PAd) in newly diagnosed myeloma.

We aimed at demonstrating non-inferiority of bortezomib/cyclophosphamide/dexamethasone (VCD) compared to bortezomib/doxorubicin/dexamethasone (PAd) induction therapy with respect to very good partial response rates or better (⩾VGPR) in 504 newly diagnosed, transplant-eligible multiple myeloma patients. VCD was found to be non-inferior to PAd with respect to ⩾VGPR rates (37.0 versus 34.

Aprepitant, granisetron, and dexamethasone for prevention of chemotherapy-induced nausea and vomiting after high-dose melphalan in autologous transplantation for multiple myeloma: results of a randomized, placebo-controlled phase III trial.

Purpose: The optimal regimen to prevent chemotherapy-induced nausea and vomiting (CINV) for patients undergoing high-dose chemotherapy and autologous stem-cell transplantation (ASCT) is unclear. To evaluate the effect of aprepitant in addition to a standard regimen, we conducted this randomized, placebo-controlled phase III trial.

Patients And Methods: Patients with multiple myeloma were randomly assigned at a one-to-one ratio to receive either aprepitant (125 mg orally on day 1 and 80 mg orally on days 2 to 4), granisetron (2 mg orally on days 1 to 4), and dexamethasone (4 mg orally on day 1 and 2 mg orally on days 2 to 3) or matching placebo, granisetron (2 mg orally on days 1 to 4), and dexamethasone (8 mg orally on day 1 and 4 mg orally on days 2 to 3).

Patients with cancer of unknown primary: a retrospective analysis of 223 patients with adenocarcinoma or undifferentiated carcinoma.

Background: Cancer of unknown primary (CUP) now accounts for 2-3% of all fatal cases of cancer in Germany. Histologically, most of these tumors are either adenocarcinoma or undifferentiated carcinoma. Scant data on their clinical features and prognosis are now available, and the published survival times are highly variable.

Plerixafor is effective given either preemptively or as a rescue strategy in poor stem cell mobilizing patients with multiple myeloma.

Background: Harvest of more than one CD34+ stem cell transplant has become the standard, to ensure the option for a second autologous transplantation in patients with relapsed or progressive multiple myeloma (MM). Additional administration of the CXCR-4 inhibitor plerixafor has been shown to increase the efficiency of CD34+ stem cell harvest. However, the algorithm when to apply plerixafor is still under debate.

Bortezomib improves outcome after SCT in multiple myeloma patients with end-stage renal failure.

Patients with multiple myeloma and dialysis-dependent renal failure have dismal outcomes. In this retrospective analysis of a case series, we evaluated 27 consecutive patients, all of whom required haemodialysis at the time of first-line induction therapy with either bortezomib or a standard regimen followed by high-dose chemotherapy and auto-SCT. The overall response rate was significantly better after bortezomib-based induction before auto-SCT (83% vs 36%, P=0.

Combination of international scoring system 3, high lactate dehydrogenase, and t(4;14) and/or del(17p) identifies patients with multiple myeloma (MM) treated with front-line autologous stem-cell transplantation at high risk of early MM progression-related death.

Purpose: To construct and validate among patients with multiple myeloma (MM) who were treated with intensive therapy a prognostic index of early MM progression-related death.

Patients And Methods: Patient-level data from the Intergroupe Francophone du Myélome (IFM) 2005-01 trial (N = 482) were used to construct the prognostic index. The event was MM progression-related death within 2 years from treatment initiation.

Sensitivity of whole-body CT and MRI versus projection radiography in the detection of osteolyses in patients with monoclonal plasma cell disease.

Purpose: To compare sensitivity of whole-body Computed Tomography (wb-CT) and whole-body Magnetic Resonance Imaging (wb-MRI) with Projection Radiography (PR) regarding each method's ability to detect osteolyses in patients with monoclonal plasma cell disease.

Patients And Methods: The bone status of 171 patients was evaluated. All patients presented with multiple myeloma (MM) of all stages, monoclonal gammopathy of unknown significance (MGUS) or solitary plasmacytoma.

Rescue stem cell mobilization with plerixafor economizes leukapheresis in patients with multiple myeloma.

While extensive data demonstrated that plerixafor improves stem cell harvest in difficult-to-mobilize patients, economic concerns limit a broader application. We retrospectively assessed the effect of an early plerixafor rescue regimen for mobilization in patients with multiple myeloma. Patients were intended for high-dose chemotherapy followed by autologous peripheral blood stem cell transplantation (ABSCT) and therefore received cyclophosphamide-based mobilization chemotherapy and consecutive stimulation with granulocyte colony-stimulating factor (G-CSF).

Predictive value of longitudinal whole-body magnetic resonance imaging in patients with smoldering multiple myeloma.

Previous studies demonstrated the relevance of focal lesions (FL) in whole-body magnetic resonance imaging (wb-MRI) at the initial workup of patients with smoldering multiple myeloma (SMM). The aim of this study was to assess the effects of longitudinal wb-MRIs on progression into multiple myeloma (MM). Sixty-three patients with SMM were analyzed who received at least two wb-MRIs for follow-up before progression into MM.

Gain of chromosome 1q21 is an independent adverse prognostic factor in light chain amyloidosis patients treated with melphalan/dexamethasone.

Chromosomal aberrations of plasma cells are well established pathogenetic and prognostic factors in multiple myeloma, but their prognostic implication in systemic light chain (AL) amyloidosis is unclear. Therefore, the aim of this study was to identify prognostic cytogenetic risk factors by interphase FISH in a series of 103 consecutive AL amyloidosis patients treated uniformly with melphalan/dexamethasone as first-line therapy. Detection of gain of 1q21 was predictive for a poor overall survival (OS) (median 12.

[Structured diagnostics and therapy of the CUP syndrome].

Background: In the majority of cases, patients with cancer of unknown primary (CUP) have a poor prognosis with no prospect of being cured. Hence, a reasonable focus of diagnostics on its essential targets seems appropriate.

Patients: Particularly important is the identification of all patients who can be assigned to subgroups with a favorable prognosis and who might benefit from a specific therapy.

[Cancer of unknown primary. Epidemiology and pathogenesis].

Definition: The term cancer of unknown primary (CUP) describes by definition epithelial malignancies for which no primary tumor can be found after primary diagnostics have been performed.

Epidemiology: The CUP syndrome constitutes 2-3% of all fatal cases of malignancies in both men and women. The proportion of women has increased in parallel to the increase of tobacco consumption in women.

Autologous stem cell transplantation for elderly patients with newly diagnosed multiple myeloma in the era of novel agents.

Background: High-dose therapy (HDT) with autologous stem cell transplantation (ASCT) is considered the standard of care for multiple myeloma (MM) patients <65 years. Safety and outcome of ASCT for patients >65 years is currently uncertain, especially since the introduction of novel agents for induction and maintenance therapy. Furthermore, there are no conclusive data available on risk assessment in elderly patients treated with HDT.

Extended resection of a plasmocytoma of bone and an amyloidoma of the chest wall.

Solitary plasmocytoma of bone is a rare condition of plasma cell neoplasia that presents as a single lesion. Amyloidoma of the chest wall is an uncommon presentation of solitary tissue amyloid deposition in the absence of systemic light-chain amyloidosis. This report describes a patient with both uncommon conditions.
