This paper studies the pattern and timing of metastatic spread in esophageal adenocarcinoma (EAC) because of the the poor outcomes. 388 samples from across 18 individuals with EAC were analysed using whole-genome sequencing and phylogenetic analysis and showed that in 90% of patients multiple subclones from the primary tumor spread very rapidly from the primary site to form multiple metastases. These include lymph nodes and distant tissues- a mode of dissemination also called 'clonal diaspora'. Metastatic subclones at autopsy were present in tissue and blood samples from earlier time points. These findings will impact the understanding and clinical evaluation of EAC.

Phase and polarisation of coherent light are highly perturbed by interaction with microstructural changes in premalignant tissue, holding promise for label-free detection of early tumours in endoscopically accessible tissues such as the gastrointestinal tract. Flexible optical multicore fiber (MCF) bundles used in conventional diagnostic endoscopy and endomicroscopy scramble phase and polarization, restricting clinicians instead to low-contrast amplitude-only imaging. We apply a transmission matrix characterisation approach to produce full-field en-face images of amplitude, quantitative phase, and resolved polarimetric properties through an MCF. We first demonstrate imaging and quantification of biologically relevant amounts of optical scattering and birefringence in tissue-mimicking phantoms. We present an entropy metric that enables imaging of phase heterogeneity, indicative of disordered tissue microstructure associated with early tumours. Finally, we demonstrate that the spatial distribution of phase and polarisation information enables label-free visualisation of early tumours in esophageal mouse tissues, which are not identifiable using conventional amplitude-only information.

Organismal ageing is a complex process driving progressive impairment of functionality and regenerative potential of tissues. Cellular senescence is a state of stable cell cycle arrest occurring in response to damage and stress and is considered a hallmark of ageing. Senescent cells accumulate in multiple organs during ageing, contribute to tissue dysfunction and give rise to pathological manifestations. Senescence is therefore a defining feature of a variety of human age‐related disorders, including cancer, and targeted elimination of these cells has recently emerged as a promising therapeutic approach to ameliorate tissue damage and promote repair and regeneration. In addition, in vivo identification of senescent cells has significant potential for early diagnosis of multiple pathologies. Here, we review existing senolytics, small molecules and drug delivery tools used in preclinical therapeutic strategies involving cellular senescence, as well as probes to trace senescent cells. We also review the clinical research landscape in senescence and discuss how identifying and targeting cellular senescence might positively affect pathological and ageing processes.

We have worked with the author of the original roadmap for cancer imaging biomarkers, Prof. James O’Connor, and leading biophotonics expert Prof. Brian Pogue to develop a dedicated roadmap for clinical implementation tailored specifically to optical-imaging biomarkers. The perspective draws on two case studies: the endoscopic visualisation of dysplasia in Barrett’s oesophagus in secondary care and the detection of malignant melanoma in primary care. These are used to identify key characteristics that are important for successful clinical implementation and highlight key decision points in the pathway.

Hyperspectral imaging (HSI) enables visualisation of morphological and biochemical information, which could improve disease diagnostic accuracy. Unfortunately, the wide range of image distortions that arise during flexible endoscopy in the clinic have made integration of HSI challenging. To address this challenge, we demonstrate a hyperspectral endoscope (HySE) that simultaneously records intrinsically co-registered hyperspectral and standard-of-care white light images, which allows image distortions to be compensated computationally and an accurate hyperspectral data cube to be reconstructed as the endoscope moves in the lumen. Evaluation of HySE performance shows excellent spatial, spectral and temporal resolution and high colour fidelity. Application of HySE enables: quantification of blood oxygenation levels in tissue mimicking phantoms; differentiation of spectral profiles from normal and pathological ex vivo human tissues; and recording of hyperspectral data under freehand motion within an intact ex vivo pig oesophagus model. HySE therefore shows potential for enabling HSI in clinical endoscopy.

Collaborative research by statistician Matt Barclay (Public Health and Primary Care) with Georgios Lyratzopoulos, Fiona Walter (Public Health and Primary Care), Sarah Jefferies (CUH, Oncology), Michael Peake (University of Leicester) and Robert Rintoul (Oncology) strongly suggests that lung cancer follow-up should be extended from five to ten years.
Five-year survival of patients with lung cancer has doubled in England during the past 15 years as lung cancer treatment has become more effective. This new study, published in the BMJ journal Thorax, finds that amongst lung cancer survivors, particularly women, there is a higher risk of getting a second smoking-related cancer for at least a decade from the time of the first primary lung cancer diagnosis. The population-based cohort study shows that those aged 50–79 at first diagnosis are at particularly high risk.
The new evidence strongly suggests the need for extended lung cancer follow-up and surveillance for other smoking-related cancers including head and neck, laryngeal and oesophageal squamous cell carcinoma, will need careful evaluation.

Cambridge researchers have developed an online calculator to be used in GP surgeries, which should enable high levels of breast cancer risk stratification in the general population and women with family history. BOADICEA is the first comprehensive calculator for the risk of developing the disease combining information on family history and more than 300 genetic indicators for breast cancer, with other factors such as weight, age at menopause, alcohol consumption and use of hormone replacement therapy. It is anticipated this will facilitate informed decision-making on individualised prevention therapies and screening for breast cancer.

The dynamics of genetic diversity in clonal populations is poorly understood, yet has important implications for treatment of microbial infections and cancer. In this study we combined a novel DNA barcoding technology in yeast, mathematical modelling and single-cell derived sequencing to probe the genetic diversity of clonally evolving cell populations. We found that there are predictable expansions and crashes in genetic diversity that emerge due to the population dynamics. Exploiting these neutral oscillations could have important implications for how we treat diseases (e.g. cancer) caused by clonal evolution of large cell populations.

The extent to which cells in normal tissues accumulate mutations throughout life is poorly understood - some mutant cells expand into clones that can be detected by genome sequencing. This paper mapped mutant clones in normal esophageal epithelium from nine donors which showed that mutations accumulated with age and were caused mainly by intrinsic mutational processes. The authors noted that, even if they do not contribute to carcinogenesis, drivers of benign clonal expansions could still appear as recurrently mutated genes in cancer genomes owing to their high mutation frequency in the normal cells from which tumors evolve. Better understanding of the mutational landscape in normal tissues may thus help refine current catalogs of cancer-driver genes, with important implications for early diagnosis and targeted therapy.

This study argues that the patchwork of clones carrying oncogenic mutations in sun-exposed human epidermis is shaped by both phenotypic adaptation and cell competition. Understanding how mutant progenitor clones interact is key to understanding not only epidermal physiology, but also the formulation of rational approaches to prevent malignant transformation.

In this cost-effectiveness study, a life-table model of a hypothetical cohort of 364 500 women finds that targeting screening to women at higher risk of breast cancer is associated with reduced overdiagnosis and reduced cost of screening without compromising quality-adjusted life-years gained and while maintaining reduced breast cancer deaths. This suggests that the cost-effectiveness and the benefit-to-harm ratio of breast screening programs could be improved by adopting a risk-stratified screening strategy.

A brief summary of the paper by lead author Daniel Muñoz-Espín
Senescent cells are present in many diseases where they play an active pathological role. A common feature of senescent cells is their high content of lysosomes. Here, it is reported a pharmacological vehicle with lysosomal tropism that preferentially releases drugs into senescent cells.
Drugs encapsulated with galacto-oligosaccharides (gal-encapsulation) are released into cells after digestion with lysosomal b-galactosidase and this happens more efficiently in senescent cells. We demonstrate that gal-encapsulated drugs are preferentially released into damaged tissues containing senescent cells, such as bleomycin-induced lung fibrosis in mice. The release of gal-encapsulated doxorubicin into fibrotic lungs results in remarkable reduction in the abnormal amount of collagen present and in recovery of respiratory function. In the case of xenograft tumors, mice are treated with senescence-inducing chemotherapy, and concomitant treatment with gal-encapsulated doxorubicin results in full tumor regression. Gal-encapsulation has the additional advantage of reducing the exposure of non-target organs to the drugs.
This study presents proof of principle for the biological activity of a versatile encapsulation method that allows to deliver small molecules preferentially in diseased tissues containing senescent cells. This may open new diagnostic and therapeutic opportunities for severe diseases, such as pulmonary fibrosis, and in premalignant lesions accumulating senescent cells. It may also serve as a companion treatment for cancer chemotherapy.

This Perspectives article in Nature Reviews highlights that a crisis is looming for the diagnosis of gastrointestinal (GI) cancers. In the UK, urgent referrals for suspected lower gastrointestinal cancer have increased by 78% in the past 6 years, with parallel increases in endoscopy and imaging activity. This paper presents a reimagined diagnostic pathway for GI cancer in which the relationship between medical specialists and generalists could be redefined to make better use of the skills of each, while delivering optimal clinical outcomes and a good patient experience.
Author Dr Fiona Walter, head of the Cancer Group at the Primary Care Unit and Director of the CanTest Collaborative, comments: "This paper exemplifies the work of CanTest, our Cancer Research UK Catalyst award. We are developing strategies to accelerate improvement in cancer outcomes through implementation in primary care of diagnostic testing to support early detection of cancer. Our research aims to systematically evaluate new tests leading to not only optimal clinical outcomes, but also improved quality and patient safety and more cost-effective health care."

A naphthalimide-based two-photon probe (AHGa) for the detection of cell senescence is designed. The probe contains a naphthalimide core, an l-histidine methyl ester linker, and an acetylated galactose bonded to one of the aromatic nitrogen atoms of the l-histidine through a hydrolyzable N-glycosidic bond. Probe AHGa is transformed into AH in senescent cells resulting in an enhanced fluorescent emission intensity. In vivo detection of senescence is validated in mice bearing tumor xenografts treated with senescence-inducing chemotherapy.

Several large-scale efforts have systematically cataloged protein-protein interactions (PPIs) of a cell in a single environment. However, little is known about how the protein interactome changes across environmental perturbations. Current technologies only assay one PPI at a time, therefore a highly parallel protein-protein interaction sequencing (PPiSeq) platform is developed that uses a novel double barcoding system in conjuction with the dihydrofolate reductase protein-fragment complementation assay in Saccharomyces cerevisiae.

The potential for an ultrasound-based screening programme for renal cell carcinoma (RCC) to improve survival through early detection has been the subject of much debate. The prevalence of ultrasound-detected asymptomatic RCC is an important first step to establishing whether a screening programme may be feasible. This meta-analysis suggests that screening 1000 individuals would result in four patients undergoing further imaging of a renal mass, and that at least one of these patients would be diagnosed with RCC . The majority (84%) of tumours screen-detected by ultrasound were early stage (T1–T2 N0).
