Real World Outcomes in Patients With Recurrent, Advanced, or Metastatic Endometrial Cancer Treated With Lenvatinib Plus Pembrolizumab.

Aims: Patients with endometrial cancer who progress following first line therapy have improved survival outcomes with pembrolizumab and lenvatinib (pem/len) compared with standard of care chemotherapy, as demonstrated in KEYNOTE-775. This was in a group of trial patients with good performance status and excluded those with carcinosarcoma histology. In KEYNOTE-775 pem/len was associated with significant toxicity, leading to dose reductions, treatment cessation, and patient morbidity.

Diagnosis, treatment and burden in advanced ovarian cancer: a UK real-world survey of healthcare professionals and patients.

Little is known regarding uptake of epithelial ovarian cancer (EOC) treatments or patient burden in UK real-world practice. Cross-sectional surveys of patients with advanced EOC and healthcare professionals (HCPs). 101 HCPs and 142 patients participated.

Diversity of thought: public perceptions of genetic testing across ethnic groups in the UK.

Genetic testing is becoming rapidly more accessible to the general populous either through or outside healthcare systems. Few large-scale studies have been carried out to gauge public opinion in this growing area. Here, we undertook the largest cross-sectional study on genetic testing in the UK.

Polymeric Carriers for Delivery of RNA Cancer Therapeutics.

As research uncovers the underpinnings of cancer biology, new targeted therapies have been developed. Many of these therapies are small molecules, such as kinase inhibitors, that target specific proteins; however, only 1% of the genome encodes for proteins and only a subset of these proteins has 'druggable' active binding sites. In recent decades, RNA therapeutics have gained popularity due to their ability to affect targets that small molecules cannot.

The Genomic Landscape of Early-Stage Ovarian High-Grade Serous Carcinoma.

Purpose: Ovarian high-grade serous carcinoma (HGSC) is usually diagnosed at late stage. We investigated whether late-stage HGSC has unique genomic characteristics consistent with acquisition of evolutionary advantage compared with early-stage tumors.

Experimental Design: We performed targeted next-generation sequencing and shallow whole-genome sequencing (sWGS) on pretreatment samples from 43 patients with FIGO stage I-IIA HGSC to investigate somatic mutations and copy-number (CN) alterations (SCNA).

Glomerular filtration rate estimation for carboplatin dosing in patients with gynaecological cancers.

Background: Carboplatin remains integral for treatment of gynaecological malignancies and dosing is based on glomerular filtration rate (GFR). Measurement via radiotracer decay [nuclear medicine GFR (nmGFR)] is ideal. However, this may be unavailable.

Safe administration of chemotherapy in mast cell activation syndrome.

Introduction: Mast Cell Activation Syndrome (MCAS) is an immunogenic disorder typically presenting with episodic multi-organ symptoms, caused by the inappropriate and aberrant release of mast cell mediators. Symptoms may be severe, including anaphylaxis and often occur in response to specific triggers which include many drugs and potentially chemotherapeutic agents. The administration of adjuvant chemotherapy and radiotherapy in endometrial cancer significantly reduces the risk of reoccurrence in patients with high risk disease.

Practical guidance for the management of side effects during rucaparib therapy in a multidisciplinary UK setting.

The use of targeted therapeutics known as poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors in the management of ovarian cancer is currently transforming clinical practice. The PARP inhibitor rucaparib is indicated in the UK, European Union and the United States for use in the treatment and maintenance settings for patients with relapsed ovarian cancer. Here, we discuss some of the real-world challenges and side effects that we have encountered while prescribing rucaparib, and we provide practical guidance on how the individual members of our multidisciplinary team (MDT), including a clinician, chemotherapy nurse practitioner, and clinical pharmacist, collaborate to manage these side effects.

Oncologist-led BRCA 'mainstreaming' in the ovarian cancer clinic: A study of 255 patients and its impact on their management.

Although guidelines recommend BRCA testing for all women with non-mucinous epithelial ovarian cancer, there is significant variability in access to testing across the UK. A germline BRCA mutation (BRCAm) in ovarian cancer patients provides prognostic and predictive information and influences clinical management, such as the use of PARP inhibitors, which have demonstrated a progression-free survival benefit in the BRCAm cohort. Additionally, the finding of a BRCAm has significant implications for patients and their families in terms of cancer risk and prevention.

CRISPR/Cas9-Mediated Trp53 and Brca2 Knockout to Generate Improved Murine Models of Ovarian High-Grade Serous Carcinoma.

There is a need for transplantable murine models of ovarian high-grade serous carcinoma (HGSC) with regard to mutations in the human disease to assist investigations of the relationships between tumor genotype, chemotherapy response, and immune microenvironment. In addressing this need, we performed whole-exome sequencing of ID8, the most widely used transplantable model of ovarian cancer, covering 194,000 exomes at a mean depth of 400× with 90% exons sequenced >50×. We found no functional mutations in genes characteristic of HGSC (Trp53, Brca1, Brca2, Nf1, and Rb1), and p53 remained transcriptionally active.

RAD51 and BRCA2 Enhance Oncolytic Adenovirus Type 5 Activity in Ovarian Cancer.

Unlabelled: Homologous recombination (HR) function is critically important in high-grade serous ovarian cancer (HGSOC). HGSOC with intact HR has a worse prognosis and is less likely to respond to platinum chemotherapy and PARP inhibitors. Oncolytic adenovirus, a novel therapy for human malignancies, stimulates a potent DNA damage response that influences overall antitumor activity.

Pharmacological Inhibition of β3 Integrin Reduces the Inflammatory Toxicities Caused by Oncolytic Adenovirus without Compromising Anticancer Activity.

Adenoviruses have been clinically tested as anticancer therapies but their utility has been severely limited by rapid, systemic cytokine release and consequent inflammatory toxicity. Here, we describe a new approach to tackling these dangerous side effects. Using human ovarian cancer cell lines as well as malignant epithelial cells harvested from the ascites of women with ovarian cancer, we show that tumor cells do not produce cytokines in the first 24 hours following in vitro infection with the oncolytic adenovirus dl922-947.

Paclitaxel resistance increases oncolytic adenovirus efficacy via upregulated CAR expression and dysfunctional cell cycle control.

Resistance to paclitaxel chemotherapy frequently develops in ovarian cancer. Oncolytic adenoviruses are a novel therapy for human malignancies that are being evaluated in early phase trials. However, there are no reliable predictive biomarkers for oncolytic adenovirus activity in ovarian cancer.

Carboplatin AUC 10 for IGCCCG good prognosis metastatic seminoma.

Objective: Metastatic seminoma is a highly curable disease. Standard treatment comprises of combination chemotherapy. The short- and long-term toxicities of this treatment are increasingly recognised and the possibility of over treatment in such a curable disease should be considered.

Failure of translation of human adenovirus mRNA in murine cancer cells can be partially overcome by L4-100K expression in vitro and in vivo.

Adaptive immune responses may be vital in the overall efficacy of oncolytic viruses in human malignancies. However, immune responses to oncolytic adenoviruses are poorly understood because these viruses lack activity in murine cells, which precludes evaluation in immunocompetent murine cancer models. We have evaluated human adenovirus activity in murine cells.

Genomic DNA damage and ATR-Chk1 signaling determine oncolytic adenoviral efficacy in human ovarian cancer cells.

Oncolytic adenoviruses replicate selectively within and lyse malignant cells. As such, they are being developed as anticancer therapeutics. However, the sensitivity of ovarian cancers to adenovirus cytotoxicity varies greatly, even in cells of similar infectivity.

New drugs for breast cancer.

Recently there have been significant advances in rational drug design for the treatment of breast cancer, especially in the area of targeted drug therapy. These include drugs which target the HER2 receptor and angiogenesis and the novel class of drug the PARP inhibitors. Some of these agents, for example, trastuzumab used in the treatment of HER2 positive breast cancer are already established as the standard of care.

Changing practice to improve pain control for renal patients.

Pain is a common symptom described by patients with end-stage kidney disease (ESKD) but remains ineffectively managed. The aim of this audit was to determine what proportion of these patients report pain, then introduce the use of an analgesic ladder adapted specifically for ESKD, and finally re-evaluate the prevalence of pain symptoms, looking for an improvement. A cohort of inpatients on the renal wards of a West London teaching hospital was studied.
