Abstract:
Background: Breast Cancer is the most common cancer in the United Kingdom and the second most common cancer in the world. Male breast cancer (MBC) is rare, but reported to account for <1 % of all breast cancer cases and 1% of all male malignancies. The management protocols for male breast cancer are largely derived from the evidence in female breast cancer management.In this study we analysed all MBC within our region presenting over a 6 year period. We are reporting the incidence, clinico-pathological features, management and outcomes of MBC patient treated in 3 breast centres serving the Mid and South Essex region of England. Material(s) and Method(s): Retrospective multicentre review of all the male breast cancer patients presented between 2014 and 2019, in Basildon Hospital, Broomfield Hospital & Southend Hospital. We identified 44 patients and collected data from their clinical records. Data related to patients' age, risk factors, histopathology,surgical treatment, adjuvant treatment and survival were analysed. Result(s): Out of 6952 cases of breast cancer diagnosed between 2014 and 2019, 44 cases of male breast cancer were identified which represents 0.63% of all cases. This lies within the international figures of incidence of male breast cancer. The age group ranged between 43 &96 years with higher incidence on the 9th decade of life. Family history was significantly linked to MBC,in our study and it was observed in 31% of cases.Smoking association with male breast cancer needs to be further assessed in a larger study as in our study group only 3 patients were actively smoking, though another 9 were ex-smokers, this gives a total of 25% of cases associated with smoking history.As for female breast cancer, Invasive ductal carcinoma (IDC) is the most common encountered histological subtype (77%), though other histopathologic subtypes were recorded including invasive lobular carcinoma (4.5%), tubular (4.5%), papillary carcinoma (4.5%) Combined IDC & ILC (2.5%) and DCIS (7%).The receptor status is comparable to the reported figures except for the triple negative cancers which showed a higher rate 6.5% compared to less than 1% rate in documented literature. Mastectomy and sentinel node biopsy remains the main line of treatment, though management with hormonal manipulation only was undertaken in 20% of patients due to frailty or metastatic disease. At a median follow-up of 3 years, 11 patients had died, but only 3 deaths were caused by breast cancer, the mortality rate in our cohort was 25%; however the MBC specific mortality in the cohort was only 6.8%. Conclusion(s): Male breast cancer is rare. It maybe associated with late presentation and less favorable outcomes. Public and health professional education is recommended to enable early disease detection. Multi-centre collaboration is suggested to allow access to a larger database for research to determine the risk factors, optimum treatment and outcomes.

Abstract:
Purpose of review: Repurposing established medicines for a new therapeutic indication potentially has important global and societal impact. The high costs and slow pace of new drug development have increased interest in more cost-effective repurposed drugs, particularly in the cancer arena. The conventional drug development pathway and evidence framework are not designed for drug repurposing and there is currently no consensus on establishing the evidence base before embarking on a large, resource intensive, potential practice changing phase III randomised controlled trial (RCT). Numerous observational studies have suggested a potential role for statins as a repurposed drug for cancer chemoprevention and therapy, and we review the strength of the cumulative evidence here.
Recent findings: In the setting of cancer, a potential repurposed drug, like statins, typically goes through a cyclical history, with initial use for several years in another disease setting, prior to epidemiological research identifying a possible chemo-protective effect. However, further information is required, including review of RCT data in the initial disease setting with exploration of cancer outcomes. Additionally, more contemporary methods should be considered, such as Mendelian randomization and pharmaco-epidemiological research with "target" trial design emulation using electronic health records. Pre-clinical and traditional observational data potentially support the role of statins in the treatment of cancer; however, randomised trial evidence is not supportive. Evaluation of contemporary methods provides little added support for the use of statin therapy in cancer. We provide complementary evidence of alternative study designs to enable a robust critical appraisal from a number of sources of the go/no-go decision for a prospective phase III RCT of statins in the treatment of cancer.

Abstract:
Background: Bowel Cancer UK and the NHS both have a focus on developing personalised care packages for patients with bowel cancer. Optimising digital information available and signposting patients to resources or events, both locally and nationally can help living well, with and beyond cancer . Method(s): A partnership was initiated between a large district general hospital and Bowel Cancer UK, to refer patients to the charity during clinical appointments, aided by leaflets and information provided on clinical letters. 'Active signposting' commenced September 2019 and will run until April 2020. A cohort of patients has completed a survey to identify uptake, aiding planning of future services. Result(s): 136 new patients were signposted to the charity to date. 70% of patients identified that they had been given information about the website from the hospital, but only 29% subsequently visited the website. 40% of patients stated that a referral letter from the hospital would make them more likely to use the website; patients did not request or identify any other new services that they would find useful. The next phase will involve signposting patients three months after diagnosis. Conclusion(s): This partnership will form part of the personalised care package for patients and is a model that other trusts could consider. Feedback received will help shape future resources and events made available to patients, and help develop a template for NHS Trusts working in partnership with Bowel Cancer UK.

Abstract:
A 67-year-old man presented to his general practitioner with intermittent episodes of unilateral sciatica over a 2-month period for which he was referred for an outpatient MRI of his spine. This evidenced a significant lumbar vertebral mass that showed tight canal stenosis and compression of the cauda equina. The patient was sent to the emergency department for management by orthopaedic surgeons. He was mobilising independently, pain free on arrival and without neurological deficit on assessment. Clinically, this patient presented with no red flag symptoms of cauda equina syndrome or reason to suspect malignancy. In these circumstances, National Institute for Health and Care Excellence guidelines do not support radiological investigation of the spine outside of specialist services. However, in this case, investigation helped deliver urgent care for cancer that otherwise may have been delayed. This leads to the question, do the current guidelines meet clinical requirements?

Abstract:
Background: Lymphoedema is a common side effect after treatment for head and neck cancer. Our treatment protocol involves staging the degree of lymphoedema and then offering treatment comprising skin care, manual lymphatic drainage, simple lymphatic drainage, compression and elastic therapeutic tape. The Glasgow Benefit Inventory is a validated post-interventional questionnaire applicable to otorhinolaryngology interventions which measures changes in health status. The aim of this study was to quantify the health benefits of lymphoedema treatment using the Glasgow Inventory Benefit questionnaire, in patients with a history of treated head and neck cancer. Method(s): Any patient who had undergone treatment with curative intent of a primary head and neck malignancy who had been referred for lymphoedema treatment within a 6 month period was eligible for inclusion. Patients completed a questionnaire after finishing the course of lymphoedema treatment. Result(s): A total of 15 patients completed the questionnaire. Ten patients (67%) demonstrated some level of improvement in quality of life, while two (13%) reported no benefit and three (20%) reported negative improvements. The average score for the total Glasgow Benefit Inventory scale was + 7.2. The greatest benefit was demonstrated with the physical benefit subscale (+ 13.1). The average general benefit score was + 9.0. Conclusion(s): Lymphoedema treatment involves techniques which can fairly easily be taught to patients to complete at home. In this study, there were mild improvements in patient reported quality of life using the Glasgow Benefit Inventory in the majority of patients. Clinical interest has increased in lymphoedema recently, but there is still limited information about the effectiveness of treatments and future research should look to address these issues.

Abstract:
Quantitative real time polymerase chain reaction (qPCR) data are normalised using endogenous control genes. We aimed to: (1) demonstrate a pathway to identify endogenous control genes for qPCR analysis of formalinfixed paraffin-embedded (FFPE) tissue using bladder cancer as an exemplar; and (2) examine the influence of probe length and sample age on PCR amplification and co-expression of candidate genes on apparent expression stability. RNA was extracted from prospective and retrospective samples and subject to qPCR using TaqMan human endogenous control arrays or single tube assays. Gene stability ranking was assessed using coefficient of variation (CoV), GeNorm and NormFinder. Co-expressed genes were identified from The Cancer Genome Atlas (TCGA) using the on-line gene regression analysis tool GRACE. Cycle threshold (Ct) values were lower for prospective (19.49+/-2.53) vs retrospective (23.8+/-3.32) tissues (p<0.001) and shorter vs longer probes. Co-expressed genes ranked as the most stable genes in the TCGA cohort by GeNorm when analysed together but ranked lower when analysed individually omitting co-expressed genes indicating bias. Stability values were<1.5 for the 20 candidate genes in the prospective cohort. As they consistently ranked in the top ten by CoV, GeNorm and Normfinder, UBC, RPLP0, HMBS, GUSB, and TBP are the most suitable endogenous control genes for bladder cancer qPCR.

Abstract:
Background: Most newly diagnosed oro-& hypopharngeal cancers (OPC, HPC) are treated with (chemo)RT with curative intent but at the consequence of adverse effects on quality of life. CRUK/14/014 investigated if using Do-IMRT to reduce RT dose to the dysphagia/aspiration related structures (DARS) improved swallowing function compared to S-IMRT. Method(s): Patients with T1-4, N0-3, M0 OPC/HPC were randomised 1:1 to S-IMRT (65 Gray (Gy)/30 fractions (f) to primary&nodal tumour; 54Gy/30f to remaining pharyngeal subsite&nodal areas at risk of microscopic disease) or Do-IMRT. The volume of the superior∣dle pharyngeal constrictor muscle (PCM) (OPC) or inferior PCM (HPC) lying outside the high-dose target volume was set a mandatory mean dose constraint in Do-IMRT. Treatment allocation was by minimisation balanced by centre, use of induction/concomitant chemotherapy, tumour site&AJCC stage. Primary endpoint was mean MD Anderson Dysphagia Inventory (MDADI) composite score 12 months after RT with 102 patients needed to detect a 10 point improvement (assuming S-IMRT score of 72, standard deviation (SD) 13.8; 90% power, 2-sided 5% alpha). Patients were blind to treatment allocation. Secondary endpoints included local control. Result(s): 112 patients (56 S-IMRT, 56 Do-IMRT) were randomised from 22 UK centres from 06/2016 to 04/2018. Mean age was 57 years; 80% were male; 97% had OPC; 90% had AJCC stage 3&4 disease; 86% had concomitant chemotherapy only, 4% induction&concomitant and 10% no chemotherapy. 111/112 had RT doses as prescribed (1 patient died before RT). Median of the mean inferior PCM dose was S-IMRT 49.8Gy (IQR 47.1-52.4) vs. Do-IMRT 28.4Gy (21.3-37.4), p < 0.0001; superior∣dle PCM dose was S-IMRT 57.2Gy (56.3-58.3) vs. Do-IMRT 49.7Gy (49.4-49.9), p < 0.0001. Do-IMRT had significantly higher MDADI scores: S-IMRT 70.3 (SD 17.3) vs. Do-IMRT 77.7 (16.1), p = 0.016. 3 local recurrences (1 S-IMRT, 2 Do-IMRT) have been reported. Conclusion(s): Do-IMRT reduced RT dose to the DARS and improved patient reported swallowing function compared with S-IMRT. This is the first randomised study to demonstrate functional benefit of swallow-sparing IMRT in OPC.

Abstract:
PURPOSE: Previous studies of hypofractionated adjuvant whole-breast radiotherapy for early breast cancer established a 15- or 16-fraction (fr) regimen as standard. The FAST Trial (CRUKE/04/015) evaluated normal tissue effects (NTE) and disease outcomes after 5-fr regimens. Ten-year results are presented. METHOD(S): Women >= 50 years of age with low-risk invasive breast carcinoma (pT1-2 pN0) were randomly assigned to 50 Gy/25 fr (5 weeks) or 30 or 28.5 Gy in 5 fr of 6.0 or 5.7 Gy (1 week). The primary end point was change in photographic breast appearance at 2 and 5 years; secondary end points were physician assessments of NTE and local tumor control. Odds ratios (ORs) from longitudinal analyses compared regimens. RESULT(S): A total of 915 women were recruited from 18 UK centers (2004-2007). Five-year photographs were available for 615/862 (71%) eligible patients. ORs for change in photographic breast appearance were 1.64 (95% CI, 1.08 to 2.49; P = .019) for 30 Gy and 1.10 (95% CI, 0.70 to 1.71; P = .686) for 28.5 Gy versus 50 Gy. alpha/beta estimate for photographic end point was 2.7 Gy (95% CI, 1.5 to 3.9 Gy), giving a 5-fr schedule of 28 Gy (95% CI, 26 to 30 Gy) estimated to be isoeffective with 50 Gy/25 fr. ORs for any moderate/marked physician-assessed breast NTE (shrinkage, induration, telangiectasia, edema) were 2.12 (95% CI, 1.55 to 2.89; P < .001) for 30 Gy and 1.22 (95% CI, 0.87 to 1.72; P = .248) for 28.5 Gy versus 50 Gy. With 9.9 years median follow-up, 11 ipsilateral breast cancer events (50 Gy: 3; 30 Gy: 4; 28.5 Gy: 4) and 96 deaths (50 Gy: 30; 30 Gy: 33; 28.5 Gy: 33) have occurred. CONCLUSION(S): At 10 years, there was no significant difference in NTE rates after 28.5 Gy/5 fr compared with 50 Gy/25 fr, but NTE were higher after 30 Gy/5 fr. Results confirm the published 3-year findings that a once-weekly 5-fr schedule of whole-breast radiotherapy can be identified that appears to be radiobiologically comparable for NTE to a conventionally fractionated regimen.

Abstract:
Introduction: Traditionally impalpable breast cancers have been localised with image guided techniques of wire guidance or ultrasound marking. Magseed is a small magnetic seed which is changing practice of localisation of these cancers. The aim of this study was to see if the change of practice of localisation to Magseed affected patient outcome evaluated by re-excision rate, specimen weight and patient satisfaction. Method(s): A change of practice service evaluation was conducted at the Shrewsbury and Telford Hospital of all patients who had imaged guided wide local excision for impalpable breast cancer from July 2017 to August 2019. Data recorded included tumour demographics, localisation method, size of tumour and specimen weight. Evaluation of localisation methods included re-excision rates, type of further surgery, cost saving in reduction in re-excision, and patient satisfaction. Result(s): 2017/2018 226 Traditional guided WLE were performed. 2018/2019 90 traditional guided WLE, and 106 Magseed WLE were performed. Tumour demographics, size of tumour were similar for localisation methods. The introduction of Magseed in our practice has resulted in a significant reduction in overall re-excision rates from 22.4 to 12%, (z =2.6616 p.00782), and average specimen weight from 40 to 27g (t= -3.2364, P.000716). Cost saving analysis of further surgery showed a saving of 34,457 with 48% less further operations following change of practice. 98% of patients had a very good/excellent experience of Magseed. Conclusion(s): Magseed demonstrates a triple effect on patient outcome with significant reduction in re-excision rate, cost saving by reducing further surgery and high patient satisfaction.
