- Coherent x-ray diffractive imaging is a powerful method for studies on nonperiodic structures on the nanoscale. Access to femtosecond dynamics in major physical, chemical, and biological processes requires single-shot diffraction data. Up to now, this has been limited to intense coherent pulses from a free electron laser. Here we show that laser-driven ultrashort x-ray sources offer a comparatively inexpensive alternative. We present measurements of single-shot diffraction patterns from isolated nano-objects with a single 20 fs pulse from a table-top high-harmonic x-ray laser. Images were reconstructed with a resolution of 119 nm from the single shot and 62 nm from multiple shots.

- Objectives The aim of this study was to compare the effect of the intensity of conditioning approaches used in allogeneic transplantation in myeloma-reduced intensity conditioning (RIC), non-myeloablative (NMA), myeloablative conditioning (MAC) or Auto-AlloHCT-on outcomes in patients who had had a prior autologous transplant. Methods A retrospective analysis of the EBMT database (1991-2012) was performed. Results A total of 344 patients aged between 40 and 60 years at the time of alloHCT were identified: 169 RIC, 69 NMA, 65 MAC and 41 Auto-Allo transplants. At a median follow-up of 54 months, the probabilities of overall survival (OS) at 5 years were 39% (95% CI 31%-47%), 45% (95% CI 32%-57%), 19% (95% CI 6%-32%) and 34% (95% CI 17%-51%), respectively. Status at allogeneic HCT other than CR or PR conferred a 70% higher risk of death and a 40% higher risk of relapse. OS was markedly lower in the MAC group (P = .004). MAC alloHCT was associated with a higher risk of death than RIC alloHCT until 2002 (HR = 4.1, P amp;lt; .001) but not after 2002 (HR = 1.2, P = .276). Conclusion From 1991 to 2002, MAC was associated with poorer OS. Between 2003 and 2012, there were no significant differences in outcomes based on these different approaches.

- BACKGROUND: Randomised, controlled trials and meta-analyses have shown the survival benefit of concomitant chemoradiotherapy or hyperfractionated radiotherapy in the treatment of locally advanced head and neck cancer. However, the relative efficacy of these treatments is unknown. We aimed to determine whether one treatment was superior to the other.METHODS: We did a frequentist network meta-analysis based on individual patient data of meta-analyses evaluating the role of chemotherapy (Meta-Analysis of Chemotherapy in Head and Neck Cancer [MACH-NC]) and of altered fractionation radiotherapy (Meta-Analysis of Radiotherapy in Carcinomas of Head and Neck [MARCH]). Randomised, controlled trials that enrolled patients with non-metastatic head and neck squamous cell cancer between Jan 1, 1980, and Dec 31, 2016, were included. We used a two-step random-effects approach, and the log-rank test, stratified by trial to compare treatments, with locoregional therapy as the reference. Overall survival was the primary endpoint. The global Cochran Q statistic was used to assess homogeneity and consistency and P score to rank treatments (higher scores indicate more effective therapies).FINDINGS: 115 randomised, controlled trials, which enrolled patients between Jan 1, 1980, and April 30, 2012, yielded 154 comparisons (28 978 patients with 19 253 deaths and 20 579 progression events). Treatments were grouped into 16 modalities, for which 35 types of direct comparisons were available. Median follow-up based on all trials was 6·6 years (IQR 5·0-9·4). Hyperfractionated radiotherapy with concomitant chemotherapy (HFCRT) was ranked as the best treatment for overall survival (P score 97%; hazard ratio 0·63 [95% CI 0·51-0·77] compared with locoregional therapy). The hazard ratio of HFCRT compared with locoregional therapy with concomitant chemoradiotherapy with platinum-based chemotherapy (CLRTP) was 0·82 (95% CI 0·66-1·01) for overall survival. The superiority of HFCRT was robust to sensitivity analyses. Three other modalities of treatment had a better P score, but not a significantly better HR, for overall survival than CLRTP (P score 78%): induction chemotherapy with taxane, cisplatin, and fluorouracil followed by locoregional therapy (ICTaxPF-LRT; 89%), accelerated radiotherapy with concomitant chemotherapy (82%), and ICTaxPF followed by CLRT (80%).INTERPRETATION: The results of this network meta-analysis suggest that further intensifying chemoradiotherapy, using HFCRT or ICTaxPF-CLRT, could improve outcomes over chemoradiotherapy for the treatment of locally advanced head and neck cancer.FUNDINGS: French Institut National du Cancer, French Ligue Nationale Contre le Cancer, and Fondation ARC.

- The use of antihuman T-lymphocyte immunoglobulin in the setting of transplantation from an HLA-matched related donor is still much debated. Acute and chronic graft-versus-host disease are the main causes of morbidity and mortality after allogeneic hematopoietic stem cell transplantation in patients with myelofibrosis. The aim of this study was to evaluate the effect of antihuman T-lymphocyte immunoglobulin in a large cohort of patients with myelofibrosis (n= 287). The cumulative incidences of grade II-IV acute graft-versus-host disease among patients who were or were not given antihuman T-lymphocyte immunoglobulin were 26% and 41%, respectively. The corresponding incidences of chronic graft-versus-host disease were 52% and 55%, respectively. Non-adjusted overall survival, disease-free survival and non-relapse mortality rates were 55% versus 53%, 49% versus 45%, and 32% versus 31%, respectively, among the patients who were or were not given antihuman T-lymphocyte immunoglobulin. An adjusted model confirmed that the risk of acute graft-versus-host disease was lower following antihuman T-lymphocyte immunoglobulin (hazard ratio, 0.54; P= 0.010) while it did not decrease the risk of chronic graft-versus-host disease. The hazard ratios for overall survival and non-relapse mortality were 0.66 and 0.64, with P-values of 0.05 and 0.09, respectively. Antihuman T-lymphocyte immunoglobulin did not influence disease-free survival, graft-versus-host disease, relapse-free survival or relapse risk. In conclusion, in the setting of matched related transplantation in myelofibrosis patients, this study demonstrates that antihuman T-lymphocyte immunoglobulin decreases the risk of acute graft-versushost disease without increasing the risk of relapse.

Systematic Modular Approaches to Reveal DNA Damage Responses in Mammalian Cells

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Cancer therapy operates by inflicting damage in malignant cells. The most lethal target is the genomic DNA. As a single double strand DNA break has the potential to kill the cell, mechanisms have evolved to detect and block propagation of the damage. Genes and their products function in a highly connected network-structure with ample cross-talk between different pathways. This interplay can be studied by genome-wide experiments, such as expression profiling. The aim of this thesis is to study the cellular effects of DNA damaging agents.A theoretical framework is explored to improve understanding of expression profiling results. To analyse large datasets, computational methods were developed to model the data. Further, the response to DNA damage was investigated in different cellular systems. As late radiation toxicity is a severe limitation of radiotherapy of cancer patients, patients were enrolled in a study to search for a molecular signature to identify high-risk patients. Ex vivo irradiation of lymphocytes revealed a signature of functionally related gene sets that were capable to separate patients with regard to toxicity status. The gene set analysis was also applied to a dataset where mouse embryonic stem cells had been exposed to various doses of cisplatin. At several time-points after administration of the drug, expression profiles were determined. In addition to the expected increase of genes related to apoptosis and cell cycle progression, damaged cells also seemed to have embarked upon a p53-dependent differentiation programme. Finally, in a study of cardiac rodent cells, the genotoxic treatment with irradiation was compared to the mechanical stress induced in heart tissue.In conclusion, this thesis presents evidence for the advantage of using functionally related sets of genes in analysis and interpretation of genome-wide experiments. This strategy may improve clinical understanding of the effects of DNA damaging agents used for cancer therapeutics.
