The present invention relates to methods for predicting the survival time of patients suffering from cancer. Said methods are based on the quantification and analysis of the cell free nucleic acids that are present in a sample from the patient and typically include the determination of the level of the mutant nucleic acid which contains a mutation of interest, the calculation of the mutation load for said mutation of interest, the calculation of the DNA integrity index or a combination thereof.

The majority of pelvic masses in women are from gynaecologic origin. However, they may also arise from the gastrointestinal or urinary tract, peritoneum or retroperitoneum, pelvic soft tissues structures or bones. The knowledge of pelvic anatomy and the imaging characteristics of these lesions are critical to provide an accurate diagnosis and a potential surgical roadmap for predicting lesion resectability. The purpose of this article is to highlight the imaging features of non-ovarian tumours of the pelvis with regard to surgical planning and identification of neoplastic and non-neoplastic lesions. © 2017 Elsevier Masson SAS.

Long-term side-effects of radiotherapy impact on the quality-of-life (QoL) of cancer survivors. These side-effects could be reduced if predicted in advance. Previous work identified clinical and biological predictors but a major, coordinated approach is needed to validate them so they can be used clinically. The EU has ~17.8 million people living with a prior diagnosis of cancer of whom ~7 million received radiotherapy. In the long-term, potentially 20% of those suffering with mild to severe side-effects (~1.4 million) might benefit from alleviation of symptoms, with resulting reductions in the cost of care in the EU. REQUITE aims to develop validated clinical models and incorporate biomarkers to identify before treatment cancer patients at risk of side-effects and use the models to design interventional trials aimed at reducing side-effects and improving QoL in cancer survivors who underwent radiotherapy. REQUITE will: 1. carry out a multi-centre, longitudinal, observational study to collect standardised data and samples in breast, prostate and lung cancer patients; 2. validate biomarkers with published evidence of predictive value; 3. replicate published clinical models and incorporate replicated biomarkers to create validated predictive algorithms; 4. use the prospectively validated models and biomarkers to design interventional trial protocols aiming to reduce side-effects and improve QoL in high-risk patients. REQUITE builds on collaborations with a proven history of data sharing, enlarged to a consortium with expertise in patient recruitment, knowledge management, biomarker testing and predictive model development. SME involvement for biomarker assays will facilitate future clinical implementation and commercial exploitation. The outcome of this project will be validated predictive models for three common cancers and trial protocols using the models to investigate interventions aimed at reducing long-term side-effects and improving the QoL of cancer survivors.

The follow-up of the Heated Intraoperative Chemotherapy (HIPEC) of peritoneal carcinomatosis would benefit from the monitoring of the penetration, distribution and metabolism of the drug within the tumor. As tumor nodules can be resected during the therapy, mass spectrometry imaging is a suitable tool for the evaluation of treatment efficacy, and, as a result, the therapy can be re-optimized. In this work we demonstrate the complementarity of laser ablation (LA) ICP mass spectrometry and MALDI imaging to study the penetration and distribution of two Pt-based metallodrugs (cisplatin and oxaliplatin) in human tumor samples removed from patients diagnosed with colorectal or ovarian peritoneal carcinomatosis. LA ICP MS offered sensitive (LOD for 195Pt 4.8 pg s-1) imaging of platinum quasi-independently of the original species and the sample matrix and thus an ultimate way of verifying the penetration of the Pt-containing drug or its moieties into the tumor. MALDI imaging was found to suffer in some cases from signal suppression by the matrix leading to false negatives. In the case of the oxaliplatin metallodrug, the results obtained from ICP and MALDI MS imaging were coherent whereas in the case of cisplatin, species detected by ICP MS imaging could not be validated by MALDI MS. The study is the first application of the dual ICP and MALDI MS imaging to the follow-up of metallodrugs in human tumors. This journal is © the Partner Organisations 2014.

The present invention relates to an association of poly (N-acryloyl glycinamide) with at least one active principle and/or at least one product which is visible in medical imaging, in a physiologically acceptable aqueous medium.


Background: Mounting evidence indicates an enhanced lymphocytic reaction as an informative prognostic indicator in colon cancer (CC). The IM methodology has been defined to quantify the in situ immune infiltrate. Methods: A Society for Immunotherapy of Cancer-led international consortium of 23 pathology expert centers from 17 countries was initiated to evaluate the standardized IM assay in routine clinical settings. Patient (pt) eligibility criteria were CC Stages I/II/III and no neo-adjuvant treatment. 1336 pts split into a training set (TS) and internal validation set (IVS) were quantified for IM using standardized procedure, immunohistochemistry using CD3 and CD8 antibodies, and quantification using digital pathology on whole slide section of primary CCs. Statistical analysis plan was predefined and all statistical analyses performed by blinded external statisticians. Primary study endpoint was timeto- recurrence (TTR); analyses were by Cox models stratified by enrolling center. Results: Median recurrent follow-up duration across centers was 5.9 years. Overall pts: 51% male, median age 69 years, 19%/56%/25% stage I/II/III. Among pts with stages I/II/III CC, in the TS TTR was shorter among 332 pts (48.1%) with low-IM CC vs 358 pts with high-IM CC (HR (95% CI), 0.35 (0.23-0.52); P<0.0001). In the IVS (630 pts) TTR was also shorter among 303 pts with low-IM CC vs 327 pts with high- IM CC (HR (95% CI), 0.54 (0.34-0.84); P=0.006). In both groups, results were independent of pt age, sex, tumor stage and sidedness. Among pts with stage II CC, the difference in TTR between low and high-IM was significant both in the TS (HR (95% CI), 0.27 (0.14-0.51); P<0.0001) and in the IVS (HR (95% CI), 0.46 (0.24-0.87) P=0.014); multivariate results similar (TS HR (95% CI), 0.28 (0.14-0.54); P<0.0001 and IVS HR (95% CI), 0.46 (0.24-0.87); P=0.0142)). Reproducibility of the standardized IM assay was validated across centers. Conclusions: The primary endpoint of the worldwide prespecified IM study was reached. TTR was significantly longer in pts stages I/II/III with high-IM. Low-IM identified a subgroup of patients with high-risk stage II CC. © 2016 Lavoisier
