Abstract:
Background: Osteosarcoma is the most common primary bone tumor, with 10% of cases affecting the head and neck. Demographics of head and neck osteosarcoma are different from those elsewhere in the musculoskeletal system. Prognosis is strongly dependent on negative resection margins with the use of neoadjuvant chemoradiotherapy in select cases.
Description: We present a case of a 58-year-old male nonsmoker patient who presented with a lump in his left upper jaw. Clinical examination revealed an exophytic mass in the upper left tuberosity of the maxilla suspicious for squamous cell carcinoma with no associated lymphadenopathy.
Findings: Radiological investigations revealed a metabolically active left maxillary lesion with destruction of the maxillary sinus. Histologic examination of a superficial biopsy initially suggested a proliferative fibro-osseous lesion; however, a second deeper biopsy was diagnostic of osteosarcoma, and the patient was referred to a sarcoma center. Immunohistochemistry showed AE1/AE3 and CK(MNF.116) positivity in occasional cells with a Ki67 proliferation index of 60%. This was diagnostic of grade 2-3 osteosarcoma. Multidisciplinary management of the patient included neoadjuvant chemotherapy and total maxillectomy and dental prosthetic rehabilitation. The patient is still under follow-up.
Conclusions: This case of primary osteosarcoma of the maxilla is rare and scarcely reported in the literature. Clinical differential diagnoses include squamous cell carcinoma, and histologic differential diagnosis includes fibro-osseous proliferative lesions in undersampled cases. It is important to consider osteosarcoma in destructive lesions, as it requires prompt and early specialist intervention to maximize the chances of negative surgical margins, which is the mainstay of treatment for this disease for prognosis.

Abstract:
Presented by: Chris Nutting (Chris.Nutting@rmh.nhs.uk) Introduction Most newly diagnosed OPC & HPC are treated with (chemo)RT with curative intent but at the consequence of adverse effects on quality of life. DARS (ISRCTN:25458988) tested if using DO-IMRT to reduce RT dose to the dysphagia/aspiration related structures (DARS) improved swallowing function compared to S-IMRT. Materials and Methods 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; 54 Gy/ 30f to remaining pharyngeal subsite & nodal areas at risk of microscopic disease) or DO-IMRT. The volume of the superior & middle 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 assessing swallowing function included University of Washington (UW)-Qol & Performance Status Scale Head & Neck (PSS-HN) scores. Results 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 SIMRT 49.8 Gy (IQR 47.1-52.4) vs. DO-IMRT 28.4 Gy (21.3-37.4), p < 0.0001; superior & middle PCM dose was
S-IMRT 57.2 Gy (56.3-58.3) vs. DO-IMRT 49.7 Gy (49.4-49.9), p < 0.0001. At 12 months, DO-IMRT had significantly higher MDADI scores: S-IMRT mean: 70.5 (SD 17.3) vs. DO-IMRT 77.7 (16.1), p = 0.037. At 12 months the proportion of patients reporting UW-QoL as being able to swallow "as well as ever" was 40.4% for DO-IMRT & 15.2% for S-IMRT; scores of?>50 were reported for PSS-HN normalcy of diet by 70.6% DO-IMRT & 58.1% S-IMRT patients & for eating in public scores by 84.3% DO-IMRT & 74.4% S-IMRT. Conclusions DOIMRT 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:
Background: Due to the immense pressure to provide capacity for women with breast symptoms, to be seen  within two weeks, a new innovative role has been created to provide increased capacity. Introduction: The breast services see many women with conditions that are benign and easily identified upon ultrasound. The majority of these conditions occur in women under the age of 40years. The role of an advanced clinical practitioner was created to answer a service need. This role requires a highly specialised cohort of skills combining breast image interpretation, breast ultrasound and breast biopsying alongside a range of clinical competences enabling autonomous practice within clear governance.
Method(s): A new clinic was created for under 40 aged women only requiring only a breast clinical specialist and an advanced clinical practitioner, using ultrasound for assessment. Unexpected findings suspicious upon ultrasound-would be redirected to the next consultant led clinic for full imaging assessment and biopsy.
Result(s): Increased capacity was achieved, without increased costs. Anxiety levels were reduced due to these patients seen within these clinics and more specialist skills could be directed to more complex cases in the traditional cancer clinics.
Conclusion(s): The use of this specialist role has proven to be innovative and specialised in answering capacity issues within the workforce. The ACP role is utilised as a support to all clinics working alongside consultant radiographers as well as in an autonomous role, thereby freeing up the consultants for cases requiring specialist skills. The stability of the breast service has been ensured

Abstract:
Background and Purpose: Male breast cancer is rare whereas gynaecomastia is very common. Only asymmetrical gynaecomastia require breast imaging and focal lumps are amenable to clinical core biopsy. So the use of ultrasound in the assessment of male breast should be limited. The aim of this study is to audit the referral indications and ultrasound outcomes in male breast US (MBUS) patients against local guidelines.
Method(s): In the last 5 years, 968 patients were referred for MBUS in our Trust. This audit includes the patients between 02/01/2019-04/12/2019. The duplicate patients and follow-ups were excluded from the study. In total, 197 patients were analysed (mean age: 58 (8-90) retrospectively. Referral diagnosis, age, US grading and clinical outcomes were noted.
Result(s): Of the 197 patients, 79% were gynecomastia (133), lipoma (21) or fat necrosis (2), and 15% (30) were normal. There was 1 chest wall lymphoma and 1 DCIS, and 9 (5%) patients had benign breast disease (fibroepithelial lesions, abscess, papilloma, sebaceous cysts, haematoma). In 122 patients (62%) clinical grade was not given, 66 had P2, 8 had P3, 1 had P5. 2 patients were scored as U4 and 4 patients as U3.
Conclusion(s): These results clearly show that 99% of the patients referred to MBUS were benign. And also 95% of the patients were clinically benign or not assessed. The excessive use of MBUS without a clinical indication leads to patient anxiety, increased waiting times and might delay the proper imaging to the patients who should have the priority in terms of clinical indication. Careful clinical assessment before ultrasound referral is mandatory for better care.

Abstract:
Introduction: To improve cancer detection rates, personal performance and as part of our routine service improvement programme, an audit was undertaken of discordant cases returned directly to routine recall between 1/4/15 and 31/3/17 inclusive. These were reviewed against the results of the subsequent screening round to determine if the correct judgement had been made at the previous screening round or if there were any opportunities to learn from misinterpretation.
Method(s): All cases arbitrated and directly returned to routine screening between 2015/16 and 2016/17 were identified and crossreferenced with the results for the subsequent screening episode. All screen detected cancers previously arbitrated on the same side were reviewed by the same routine method and criteria as all interval cancers within our unit and each was given an 'interval' category. All of the screen detected cancers previously arbitrated on the same side were included in the annual interval cancer review session to discuss learn opportunities and improved outcomes.
Result(s): There were 829 cases arbitrated and returned to routine screening at the original screening episode 2015/16 or 2016/17. 11 cases were diagnosed with a same side screen detected cancer at the subsequent screening round and 2 cases presented as a same side interval cancer. Neither interval cancers detected at the case review. 1 of the 11 same side screen detected cancers classified as minimal signs.
Conclusion(s): In our unit arbitration cases returned to routine recall is the correct decision in the vast majority.

Abstract:
The subspecialty of cardio-oncology aims to reduce cardiovascular morbidity and mortality in patients with cancer or following cancer treatment. Cancer therapy can lead to a variety of cardiovascular complications, including left ventricular systolic dysfunction, pericardial disease, and valvular heart disease. Echocardiography is a key diagnostic imaging tool in the diagnosis and surveillance for many of these complications. The baseline assessment and subsequent surveillance of patients undergoing treatment with anthracyclines and/or human epidermal growth factor (EGF) receptor (HER) 2-positive targeted treatment (e.g. trastuzumab and pertuzumab) form a significant proportion of cardio-oncology patients undergoing echocardiography. This guideline from the British Society of Echocardiography and British Cardio-Oncology Society outlines a protocol for baseline and surveillance echocardiography of patients undergoing treatment with anthracyclines and/or trastuzumab. The methodology for acquisition of images and the advantages and disadvantages of techniques are discussed. Echocardiographic definitions for considering cancer therapeutics-related cardiac dysfunction are also presented.

Abstract:
Introduction: Recommendations were issued to the hospital Trusts to configure service delivery to balance cancer care with the safety of the patient and the hospital staff during the COVID-19 pandemic. The public felt the service restrictions might lead to delays in diagnosis and treatment of cancer patients. We compared the management of 2ww breast referrals in our centre between May to July 2019 and 2020. Method(s): We triaged all referrals to face-face consultation or initial telephone consultation during the pandemic. Patients with suspicious symptoms were offered face-face consultation after the telephone triage. Result(s): Overall, breast patients' referrals fell by 28.3% during the pandemic. 10.2% reduction was noted in May (95% CI 6.73 – 13.59, p<0.001) but a non-significant increase was recorded in June and July. Waiting time reduced by 8.43 days (95% CI -8.88 to -7.98, p< 0.0001). Breast cancer suspicion increased across all age groups in 2020 (+10.4% to + 16.2%). Breast cancer diagnosis rose by 2.0% in 2020 (95% CI 0.19 – 3.92, p=0.030). No cancer was diagnosed among under 29 years. 29.1% of the 522 patients triaged to telephone consultation were discharged, and 70.9% needed face-to-face follow-up. One patient discharged after telephone consultation was later diagnosed with breast cancer. Conclusion(s): COVID-19 pandemic did not lead to a prolonged waiting time or reduced breast cancer diagnosis, but there was an overall reduction in referrals to our breast service.

Abstract:
Background: Prognostic value of circulating tumour cells (CTC) in breast cancer is currently under investigation. This systematic review with Meta-analysis measures the evidence on prognostic relevance of CTC in early breast cancer presented in recent published studies. Method(s): A detailed search was made for published primary studies, those assessed prognostic value of CTC in early breast cancer. Review and quality assessment of 22 included studies were performed and data on CTC status and disease recurrence and death were extracted. Primary outcomes analysed were hazard ratios for disease-free survival (DFS) and overall survival (OS) between the patient groups with positive and negative detection of CTC. Meta-analysis calculated the pooled hazard ratio (HR) with 95% confidence intervals (CIs) as the overall effect measure on DFS and OS using the fixed and random effects models. Result(s): 22 studies enrolling total of 5724 patients were eligible for the systematic review and meta-analysis. Pooled HR for DFS: 2.81 (CI: 2.20-3, 61) and for OS: 2.74 (CI: 2.20-3.41) was found with CTC positive status. Conclusion(s): This systematic review and meta-analysis finds that positive detection of CTC in early breast cancer is a poor prognostic index for disease recurrence and mortality by nearly 3 times.

Abstract:
Bone tumours are uncommon diagnoses and there is often a delay from first presentation to a healthcare professional (HCP) to definitive diagnosis and management. Patients may present to secondary care in a number of ways. Patients may present acutely with pathological (or impending) fractures, patients may present as urgent 2-week referral from primary care or patients may present with incidental findings on radiological investigations. A thorough history and examination is essential, followed by radiological investigations. Common clinical findings include pain, which is usually the main reason for patient presentation to an HCP. Other reasons include limp or loss of function of limb, swelling or lump, or pathological fracture. As part of the work-up, it is important to ask about constitutional symptoms, past history of malignancy and family history of known syndromes. Plain radiographs are vital for diagnosis. The patient's age is important for the differential diagnosis. The location, morphology and how the tumour is affecting the bone, periosteum and soft tissues are key to the diagnosis. For patients presenting with bone lesions, it is essential to follow the bone sarcoma referral guidelines so that patients are promptly diagnosed and treated.
