The genomic landscape of response to EGFR blockade in colorectal cancer.

Colorectal cancer is the third most common cancer worldwide, with 1.2 million patients diagnosed annually. In late-stage colorectal cancer, the most commonly used targeted therapies are the monoclonal antibodies cetuximab and panitumumab, which prevent epidermal growth factor receptor (EGFR) activation.

Family history as a marker of platinum sensitivity in pancreatic adenocarcinoma.

Purpose: Metastatic pancreatic adenocarcinoma is considered a uniformly fatal disease with a median survival of 1 year with modern chemotherapy. While a subset of patients achieve prolonged survival, few of the factors that define this group of patients are known.

Methods: For the determination of overall survival (OS), 549 patients with histologically confirmed metastatic pancreatic adenocarcinoma were evaluated.

Genomic analyses of gynaecologic carcinosarcomas reveal frequent mutations in chromatin remodelling genes.

Malignant mixed Müllerian tumours, also known as carcinosarcomas, are rare tumours of gynaecological origin. Here we perform whole-exome analyses of 22 tumours using massively parallel sequencing to determine the mutational landscape of this tumour type. On average, we identify 43 mutations per tumour, excluding four cases with a mutator phenotype that harboured inactivating mutations in mismatch repair genes.

Imaging of musculoskeletal bacterial infections by [124I]FIAU-PET/CT.

Background: Traditional imaging techniques for the localization and monitoring of bacterial infections, although reasonably sensitive, suffer from a lack of specificity. This is particularly true for musculoskeletal infections. Bacteria possess a thymidine kinase (TK) whose substrate specificity is distinct from that of the major human TK.
