Shortening adjuvant chemotherapy in stage III colon cancer: are we ready for a change?
2018
Oxaliplatin-based adjuvant chemotherapy for 6 months is considered the standard of care after a curative resection in patients with stage III colon cancer. The addition of oxaliplatin provides a benefit on overall survival confirmed in three randomised phase 3 trials1–3 with an long-term absolute increase ranging from 2.7% to 6%. Since oxaliplatin was incorporated into the adjuvant setting more than a decade ago, the standard in adjuvant therapy has remained unchanged because of the lack of novel agents with relevant activity in this scenario. Unfortunately, this combination can have also acute and long-term side effects that can interfere with daily life activities in potentially cured pat…
Analysis of relapse after transplantation in acute leukemia: A comparative on second allogeneic hematopoietic cell transplantation and donor lymphocy…
2018
Relapse of acute leukemia (AL) after allogeneic hematopoietic cell transplantation (Allo-HCT) entails a dismal prognosis. In this scenario, donor lymphocyte infusions (DLIs) and second Allo-HCT are two major approaches. We compared outcomes of AL patients treated for relapse with DLI or second Allo-HCT after receiving debulking therapy. In total, 46 patients were included in the study; 30 (65%) had acute myeloid leukemia and 16 (35%) had acute lymphoblastic leukemia. The median age was 38 years (range 4-66). Twenty-seven patients received a second Allo-HCT and 19 patients received DLI. The median follow-up of the cohort was 273 days (range 9-7013). Overall survival (OS), disease-free surviv…
Squamous Cell Carcinoma: Clinical and Pathological Features and Associated Risk Factors in an Observational Study of 118 Patients
2015
Background and objective: In the latest edition of its cancer staging manual, the American JointCommittee on Cancer (AJCC) revised the criteria for staging squamous cell carcinoma (SCC) by introducing high-risk tumor features to define tumor stage (T) and help to identify tumors with a higher risk of metastasis. The aim of this study was to investigate the characteristics associated with SCC meeting the high-risk criteria defined by the AJCC for T2 lesions. Patients and method: We performed a case-case observational study in which patients with SCC were included over a period of 18 months. We collected clinical, anthropometric, and tumor data, and analyzed these using PASW Statistics (SPSS)…
Cohort study of occupational cosmic radiation dose and cancer mortality in German aircrew, 1960-2014.
2020
ObjectivesTo determine cancer mortality compared with the general population and to examine dose-response relationships between cumulative occupational radiation dose and specific cancer outcomes in the German aircrew cohort.MethodsFor a cohort of 26 846 aircrew personnel, standardised mortality ratios (SMR) were calculated. Dose-response analyses were carried out using Poisson regression to assess dose-related cancer risks for the period 1960–2014. Exposure assessment comprises recently available dose register data for all cohort members and newly estimated retrospective cabin crew doses for 1960–2003.ResultsSMR for all-cause, specific cancer groups and most individual cancers were reduced…

Dose-response relationship in the context of a maintenance randomized control trial: reanalysis of the PRODIGE 9 trial
2019
Introduction The dose-response relationship is considered as one of the major criteria when the causality of a relationship between an exposure and an outcome is discussed. This criterion is mainly studied in observational studies but may be also of interest in Randomized Controlled Trial (RCT), particularly if the administered dose of treatment varies over time and between patients. Maintenance trials with a long follow-up meet these characteristics. We reanalyzed a maintenance trial in digestive oncology (PRODIGE 9 trial) in order to explore the dose-response relationship between the maintenance treatment and overall survival (OS). Methods The PRODIGE 9 study was a maintenance trial asses…
Pediatric second primary malignancies after retinoblastoma treatment
2015
Background Children with retinoblastoma carry a high risk to develop second primary malignancies in childhood and adolescence. This study characterizes the type of pediatric second primary malignancies after retinoblastoma treatment and investigates the impact of different treatment strategies and prognostic factors at presentation. Procedure All national patients treated for retinoblastoma at the German referral center with a current age of 6–27 years were invited to participate in a study to characterize late effects. Results Data on pediatric second primary malignancies were recorded from 488 patients. Ten developed a malignancy before the age of 18 years. For children with heterozygous …

Midostaurin in Combination with Intensive Induction and As Single Agent Maintenance Therapy after Consolidation Therapy with Allogeneic Hematopoietic…
2015
Abstract Background: Internal tandem duplications (ITD) in the receptor tyrosine kinase FLT3 occur in roughly 25% of younger adult patients (pts) with acute myeloid leukemia (AML), implicating FLT3 as a potential target for kinase inhibitor therapy. The multi-targeted kinase inhibitor midostaurin shows potent activity against FLT3 as a single agent but also in combination with intensive chemotherapy. Aims: To evaluate the feasibility and efficacy of midostaurin in combination with intensive induction therapy and as single agent maintenance therapy after allogeneic hematopoietic stem cell transplantation (alloHSCT) or high-dose cytarabine (HIDAC). Methods: The study includes adult pts (age 1…
Quality of life after pulmonary stereotactic fractionated radiotherapy (SBRT): Results of the phase II STRIPE trial.
2019
Preserving health related quality of life (HRQOL) plays an important role in considering stereotactic body fractionated radiotherapy (SBRT). The prospective monocenter phase II STRIPE trial investigated long-term HRQOL after SBRT, efficacy and toxicity.Patients with ≤2 pulmonary lesions ≤5 cm were treated with 4DPET/CT-based SBRT (3 × 12.5 Gy or risk-adapted 5 × 7 Gy, to 60% isodose). Follow up (FU) was performed 2 and 7 weeks after SBRT, then 3-monthly for 2 years with assessment of response (primary endpoint: 2-year cumulative incidence of local progression (LP); secondary endpoints: local progression free survival (LPFS), overall survival (OS) and toxicity (CTCAE)). Impact of predefined …
