Background: Although intensified chemotherapy regimens have improved tumour control and survival in advanced-stage Hodgkin's lymphoma, data on the long-term sequelae are scarce. We did preplanned follow-up analyses of the German Hodgkin Study Group (GHSG) trials HD9 and HD12 to assess whether the primary results of these trials-which had shown that intensive initial therapy in advanced-stage Hodgkin's lymphoma has a beneficial effect on treatment outcomes-would continue with longer follow-up.

Methods: In HD9 (Feb 1, 1993, to March 10, 1998), 1282 patients with newly diagnosed, histology-proven, advanced-stage Hodgkin's lymphoma received eight alternating cycles of COPP and ABVD (COPP/ABVD), eight cycles of bBEACOPP, or eight cycles of eBEACOPP.

Introduction: Despite advances in adjuvant chemotherapy, 20-30% of patients in stages II-III colorectal cancer will eventually relapse. Observational studies showed a reduction in relapse rate, colon cancer-specific mortality, and overall mortality by physical activity. Results from prospective randomized interventional studies to confirm these observational data are lacking.

Background/aim: Although high response rates using the doublet-chemotherapy of oxaliplatin and irinotecan as well as its combination with cetuximab in advanced gastric cancer were shown in previous trials, time to progression was short, suggesting acquired chemotherapy resistance.

Patients And Methods: Sequential chemotherapy (oxaliplatin and irinotecan followed by docetaxel) combined with bevacizumab was investigated in the GASTRIC-3 trial. Patients achieving at least stable disease were continued on maintenance bevacizumab.

Background: In many patients with chronic lymphocytic leukaemia requiring treatment, induction therapy with rituximab plus chemotherapy improves outcomes compared with chemotherapy alone. In this study we aimed to investigate the potential of rituximab maintenance therapy to prolong disease control in patients who respond to rituximab-containing induction regimens.

Methods: In this randomised, international, multicentre, open-label, phase 3 clinical trial, we enrolled patients who had achieved a complete response (CR), CR with incomplete bone marrow recovery (CRi), or partial response (PR) to first-line or second-line rituximab-containing chemoimmunotherapy and randomly assigned them in a 1:1 ratio (central block randomisation in the electronic case report form system) to either intravenous rituximab 375 mg/m(2) every 3 months, or observation alone, for 2 years.

Iron deficiency and iron deficiency-associated anemia are common complications in cancer patients. Most iron deficient cancer patients present with functional iron deficiency (FID), a status with adequate storage iron, but insufficient iron supply for erythroblasts and other iron dependent tissues. FID is the consequence of the cancer-associated cytokine release, while in absolute iron deficiency iron stores are depleted resulting in similar but often more severe symptoms of insufficient iron supply.

We investigated rituximab maintenance therapy in patients with diffuse large B-cell lymphoma (n=662) or follicular lymphoma grade 3b (n=21) in first complete remission. Patients were randomized to rituximab maintenance (n=338) or observation (n=345). At a median follow-up of 45 months, the event-free survival rate (the primary endpoint) at 3 years was 80.

Background: Trastuzumab, one important treatment option for HER2-positive metastatic breast cancer (MBC) is limited by its cardiotoxic potential. Lapatinib and pegylated liposomal doxorubicin (PLD) represent a cardiosparing alternative that can cross the blood brain barrier. This is important, because one third of breast cancer patients develop brain metastases.

Background: Acute myeloid leukemia (AML) comprises a spectrum of myeloid malignancies which are often associated with distinct chromosomal abnormalities, and the analysis of such abnormalities provides us with important information for disease classification, treatment selection and prognosis. Some chromosomal abnormalities albeit recurrent are rare such as tetrasomy 8 or isochromosome 5p. In addition, erratic chromosomal rearrangements may occur in AML, sometimes unbalanced and also accompanied by other abnormalities.

Current literature provides conflicting evidence regarding the efficacy of lenalidomide in patients with myelofibrosis (MF). The aim of this work was to evaluate the efficacy of lenalidomide in patients with MF treated within a named patient program in Austria. A total of 22 patients with MF were treated with lenalidomide in 7 different centres throughout Austria.

Currently, there is no standard systemic treatment for extranodal marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue. Both rituximab and cladribine have shown some activity in this disease, but the combination has not been tested so far. In view of this, we initiated a phase II study to assess the activity and safety of rituximab and cladribine in patients with histologically verified mucosa-associated lymphoid tissue lymphoma.

Background: Treatment of follicular lymphoma with rituximab is currently recommended at a dose of 375 mg/m(2). We aimed to provide a rationale for optimal dosing and scheduling of this anti-CD20 antibody based on pharmacokinetics.

Design And Methods: Clinical efficacy of immunochemotherapy with rituximab, fludarabine and mitoxantrone followed by 2-monthly rituximab maintenance was evaluated in 29 patients with previously untreated follicular lymphoma in a prospective phase II trial (AGMT-NHL9).

Purpose: The number of removed axillary lymph nodes and the ratio of involved to removed lymph nodes are described as independent prognostic factors beside the absolute number of involved lymph nodes in breast cancer patients. The correlation between these factors and prognosis were investigated in trials of the Austrian Breast and Colorectal Cancer Study Group (ABCSG).

Methods: This retrospective analysis is based on the data of 7052 patients with endocrine-responsive breast cancer who were randomized in four trials of the ABCSG in the years 1990-2006 and underwent axillary lymph node dissection.

Background: Patients suffering from advanced gastric cancer still have a poor prognosis and treatment options are limited. In our previous phase II trial (AGMT-Gastric-1), we showed that the combination of oxaliplatin and irinotecan was well tolerated and effective. The same chemotherapy regimen was now tested in combination with cetuximab in a multicenter phase II trial.

Over the past years, experience has been increasing with lymphatic mapping and sentinel node biopsy (SNB) after preoperative chemotherapy for breast cancer, with a wide range of results reported in the literature and final conclusions on the diagnostic value and clinical consequences of this sequential approach still missing. Between 1999 and 2002, the Austrian Breast and Colorectal Cancer Study Group (ABCSG) conducted a prospective randomized multicenter trial comparing three versus six preoperative cycles of epirubicin/docetaxel + granulocyte colony-stimulating factor for operable breast cancer. Of the 292 patients recruited to the trial overall, 111 were enrolled in a prospective subprotocol for performing LM and SNB in addition to obligatory axillary lymph node dissection (ALND) after PC.

Background: Sentinel node (SN) biopsy after preoperative chemotherapy (PC) in breast cancer patients is associated with a lower identification rate (IR) and an increased false-negative rate (FNR) compared with SN biopsy in untreated patients. Our aims were to examine the feasibility of SN mapping before PC and the possibility to assess the lymph node status after chemotherapy through a follow-up lymphatic mapping.

Methods: SN biopsy was performed in 45 clinically node-negative breast cancer patients before PC.
