Purpose At least 94 common single nucleotide polymorphisms (SNPs) are associated with breast cancer. The extent to which an SNP panel can refine risk in women who receive preventive therapy has not been directly assessed previously. Materials and Methods A risk score on the basis of 88 SNPs (SNP88) was investigated in a nested case-control study of women enrolled in the International Breast Intervention Study (IBIS-I) or the Royal Marsden study. A total of 359 women who developed cancer were matched to 636 controls by age, trial, follow-up time, and treatment arm...

INTRODUCTION: The RCPAQAP (Royal College of Pathologists of Australasia Quality Assurance Program) Haematology has undertaken an exercise to review the internal quality control protocol for full blood count (FBC) instrumentation as well as review the action taken by laboratories when nonconforming results are evident in the RCPAQAP proficiency testing reports. METHOD: A questionnaire was sent to laboratories enrolled in the RCPAQAP FBC module. Laboratories were asked to provide information with regard to the type of control measures used within their testing environment that would trigger alerts for nonconforming events...

Survival for transformed follicular lymphoma (tFL) has improved in the rituximab era and the need for upfront stem cell transplantation (SCT) is unclear. We evaluated the outcomes for all patients treated with first-line chemotherapy for histologically-proven tFL at our institution from 2003-2013 (n = 87). The majority of patients (89.7%) did not receive a SCT as part of first-line management. With a median follow-up of 7.8 years the 5-year overall survival (OS) for all patients was 61.7%. Patients treated with R-CHOP without upfront SCT (n = 55/87) had a 5-year OS of 64...

OBJECTIVES: Dose-finding trials are fundamental to develop novel drugs for children and adolescents with advanced cancer. It is crucial to maximise individual benefit, whilst ensuring adequate assessment of key study end-points. We assessed prognostic factors of survival in paediatric phase I trials, including two predictive scores validated in adult oncology: the Royal Marsden Hospital (RMH) and the MD Anderson Cancer Center (MDACC) scores. METHODS: Data of patients with solid tumours aged <18 years at enrolment in their first dose-finding trial between 2000 and 2014 at eight centres of the Innovative Therapies for Children with Cancer European consortium were collected...

BACKGROUND: Pathological complete response after chemoradiotherapy for rectal cancer occurs in 10% to 30% of patients. The best method to identify such patients remains unclear. Clinical assessment of residual mucosal abnormality is considered the most accurate method. In our institution, magnetic resonance tumor regression grade is performed as routine to assess response. OBJECTIVE: The purpose of this study was to compare the sensitivity of magnetic tumor regression grade against residual mucosal abnormality in detecting patients with a pathological complete response...

BACKGROUND: In phase 1 trials, an important entry criterion is life expectancy predicted to be more than 90 days, which is generally difficult to predict. The Royal Marsden Hospital (RMH) prognostic score that is determined by lactate dehydrogenase level, albumin level, and number of metastatic sites of disease was developed to help project patient outcomes. There have been no systematic analyses to evaluate the utility of the RMH prognostic score for esophagogastric cancer patients...

BACKGROUND: Extremity soft-tissue sarcomas comprise a range of distinct histological subtypes. This study aimed to characterize the patterns of disease relapse in patients undergoing resection of primary extremity soft-tissue sarcoma. METHODS: All patients who had resection of primary extremity soft-tissue sarcoma at the Royal Marsden Hospital between January 2004 and January 2014 were identified from an institutional database. RESULTS: In the period examined, 556 patients underwent resection...

BACKGROUND: This pilot study assessed the diagnostic accuracy of rapid evaporative ionization mass spectrometry (REIMS) in colorectal cancer (CRC) and colonic adenomas. METHODS: Patients undergoing elective surgical resection for CRC were recruited at St. Mary's Hospital London and The Royal Marsden Hospital, UK. Ex vivo analysis was performed using a standard electrosurgery handpiece with aspiration of the electrosurgical aerosol to a Xevo G2-S iKnife QTof mass spectrometer (Waters Corporation)...

BACKGROUND: We sought to validate the Royal Marsden Hospital (RMH) and MD Anderson Cancer Center (MDACC) prognostic scoring systems for the selection of bone sarcoma patients for phase I clinical trials and to identify additional risk factors related to survival. PATIENTS AND METHODS: We retrospectively reviewed the baseline characteristics and outcomes of 92 bone sarcoma patients who were referred to MDACC's Phase I Clinical Trials Program. RESULTS: Ninety-two patients with Ewing sarcoma (N = 47), osteosarcoma (N = 22), chondrosarcoma (N = 16), and other tumors (N = 7) were evaluated; 78 were enrolled in at least 1 of 43 different phase I trials...

AIM: The study aimed to establish the oncological outcome of patients who opted for close surveillance with or without adjuvant chemoradiotherapy (CRT) rather than radical surgery after local excision (LE) of early rectal cancer (ERC) METHOD: The Royal Marsden Hospital Rectal Cancer database was used to identify rectal cancer patients treated by primary LE from 2006-2015. All patients were entered in an intensive surveillance programme. RESULTS: Twenty eight of 34 analysed patients had a high or very high risk of residual disease predicted by adverse histopathological features for which the recommendation had been radical surgery...

BACKGROUND: Drugs targeting programmed death receptor-1 (PD-1) and its ligand PD-L1 have shown activity in multiple malignancies. Considering their novel mechanism of action, whether traditional prognostic scores also apply to patients treated with these drugs is unknown. We investigated whether a baseline 3-point (pt) computed tomography (CT) scan (PS3-CT) score and a 7-pt prognostic (PS7) score allowed identifying long-term survivors on anti-PD-1/-L1 therapy. MATERIALS AND METHODS: We reviewed 251 consecutive patients enrolled in phase I trials evaluating anti-PD-1/-L1 agents between 26th December 2011 and 7th September 2015...
