Assessing Mode of Recurrence in Breast Cancer to Identify an Optimised Follow-Up Pathway: 10-Year Institutional Review.

BACKGROUND: Breast cancer surveillance programmes ensure early identification of recurrence which maximises overall survival. Programmes include annual clinical examination and radiological assessment. There remains debate around the value of annual clinical exam in diagnosing recurrent disease/second primaries. The aim was to assess diagnostic modalities for recurrent breast cancer with a focus on evaluating the role of annual clinical examination. PATIENTS AND METHODS: A prospectively maintained database from a symptomatic breast cancer service between 2010-2020 was reviewed. Patients with biopsy-proven recurrence/second breast primary were included. The primary outcome was the diagnostic modality by which recurrences/secondary breast cancers were observed. Diagnostic modalities included (i) self-detection by the patient, (ii) clinical examination by a breast surgeon or (iii) radiological assessment. RESULTS: A total of 233 patients were identified and, following application of exclusion criteria, a total of 140 patients were included. A total of 65/140 (46%) patients were diagnosed clinically, either by self-detection or clinical examination, while 75/140 (54%) were diagnosed radiologically. A total of 59/65 (91%) of patients clinically diagnosed with recurrence presented to the breast clinic after self-detection of an abnormality. Four (6%) patients had cognitive impairment and recurrence was diagnosed by a carer. Two (3%) patients were diagnosed with recurrence by a breast surgeon at clinical examination. The median time to recurrence in all patients was 48 months (range 2-263 months). CONCLUSION: Clinical examination provides little value in diagnosing recurrence (< 5%) and surveillance programmes may benefit from reduced focus on such a modality. Regular radiological assessment and ensuring patients have urgent/easy access to a breast clinic if they develop new symptoms/signs should be the focus of surveillance programmes.

Assessing Clinical Acumen in Predicting Acute Appendicitis in Emergency Surgery: A Prospective Study.

BACKGROUND: Clinical acumen and experience are critical in the diagnosis of the commonest surgical emergency, acute appendicitis. However, there is an increasing focus on haematological and radiological parameters in reaching the diagnosis of appendicitis, which can negate the importance of clinical findings. The aim was to assess the accuracy of each grade of the surgical team in diagnosing acute appendicitis using clinical acuity alone and compare them to each other as well as validated predictive scores. METHODS: A prospective single-centre study was performed over a six-month period (Dec 2020-May 2021). All patients presenting to the emergency department with right iliac fossa pain were included. RESULTS: A total of 180 patients were included of whom 35% were male. Mean age was 36.2 years (range 16-91). 51.1% had a final diagnosis of appendicitis, of which 91.3% were managed surgically and 8.7% were treated conservatively with antibiotics. Consultants were correct in their prediction of appendicitis in 84.6% of cases (females-83.4%, males-86.6%). Registrars accurately predicted appendicitis in 82.2% of patients (females-80.3%, males-85.7%), whilst house officers (SHOs) and interns were right in 73.8% (females-69.2%, males-82.5%) and 72.7% (females-66.6%, males-83.9%) of cases, respectively. In patients with a histological or radiological diagnosis of appendicitis, the mean Acute Inflammatory Response Score and Acute Appendicitis Score were 7.0 (high risk ≥ 9) and 12.5 (high risk ≥ 16), respectively. Clinicians had superior diagnostic accuracy when compared with both the clinical scores used. CONCLUSION: Seniority was associated with improved diagnostic accuracy in clinically predicting acute appendicitis. This study showed that the clinical judgement of experienced surgeons is more reliable than clinical scores in the diagnosis of appendicitis.

Long-term survival in patients with node-positive breast cancer who undergo sentinel lymph node biopsy alone after neoadjuvant chemotherapy: meta-analysis.

BACKGROUND: Sentinel lymph node biopsy (SLNB) after neoadjuvant chemotherapy (NACT) in patients with breast cancer who are initially node-positive but convert to clinically/radiologically node-negative remains controversial. The primary aim was to assess pooled 5-year disease-free (DFS) and overall (OS) survival for patients who are initially node-positive but have a negative SLNB after NACT, and do not proceed to axillary lymph node dissection (ALND). METHODS: The study was performed using PRISMA guidelines. A systematic literature search of relevant databases was conducted. The Der Simonian-Laird and Cochran-Mantel-Haenszel methods were used to calculate weighted pooled estimates for OS and DFS for this group compared with patients who had NACT and proceeded to ALND after a negative or positive SLNB. RESULTS: Seven studies involving 915 patients who had a negative SLNB after NACT were included. Pooled estimates of 5-year DFS and OS in patients with a negative SLNB after NACT were 86 (95 per cent c.i. 82.1 to 90.3) and 93.1 (87.8 to 97.0) per cent respectively. Patients with a positive SLNB who underwent ALND had reduced 5-year DFS (OR 0.49, 95 per cent c.i. 0.35 to 0.69; P < 0.001) and OS (OR 0.41, 0.16 to 1.02; P = 0.06) compared with those who had a negative SLNB after NACT. There were no differences in DFS for patients who had a negative SLNB only compared with those undergoing ALND with a pCR (OR 1.65, 0.71 to 3.79; P = 0.24). CONCLUSION: Patients who are initially node-positive and who achieve a complete clinical/radiological axillary response after NACT with a subsequent negative SLNB have high rates of DFS and OS after 5 years. Patients with residual disease have significantly reduced DFS and further axillary treatment may still be warranted.

The academic impact of 20 years of Irish otolaryngology society conferences.

BACKGROUND: & Purpose: The Irish Otolaryngology Society (IOS) conference takes place annually. This conference allows surgeons and surgical trainees from Ireland and abroad an opportunity to showcase research ideas from their respective centres. This allows them to disseminate results, accept critique, and obtain different perspectives. We sought to examine research presented at the IOS meetings over 20 years. We aimed to analyse the publication rates, impact factor of journals, and citation rates of presented abstracts. METHODS: All oral presentations from IOS conferences were analysed between 2000 and 2019. Presentation titles and authors were searched using Pubmed, Google Scholar and Research Gate. We identified scientific publications which resulted from the research presented and the characteristics of each publication. RESULTS: Of 703 presentations made at the conferences spanning 20 years, 30.15% (n = 212) went on to publish their research averaging 19 citations per publication. Median time to publication was 2 years (-1-11). Each year there have been an increasing number of oral presentations with a declining publication rate. CONCLUSION: The Irish otolaryngology society meeting is a high-quality meeting with comparable publication rates to similar international conferences. Despite this, many presentations do not have any lasting impact as they are not published. The increasing pressure for trainees to rapidly present research projects without emphasis on completion of projects may explain the declining publication rate. Our study highlights the importance of completing high-quality research projects through publication. Meaningful conclusions from these projects can add to the body of knowledge and contribute to evidence-based practice.

Arthroscopic Suture-Button Versus Hook-Plate Fixation for Acromioclavicular Joint Injuries-A Systematic Review of Comparative Studies.

PURPOSE: To systematically review the comparative studies in the literature to compare joint stability, clinical outcomes, and complications of acromioclavicular joint fixation using a hook plate versus arthroscopic suture-button (SB) fixation. METHODS: A literature search was performed in accordance with the PRISMA guidelines to identify clinical studies comparing the hook plate and arthroscopic SB techniques for acromioclavicular joint injuries. Qualitative statistical analysis was performed using SPSS, and a P value of ≤.05 was considered to be statistically significant. RESULTS: Six clinical studies including 285 patients were included in the systematic review. In 3 of the studies, there was a significant difference in favor of SB for Constant score. Patients treated with the SB technique had a lower visual analog scale score at final follow-up in 2 of the 4 studies that measured this outcome. In addition, there were no significant difference in the rate of complications, revisions, or joint malreduction in any of the included studies. CONCLUSIONS: The arthroscopic SB procedure resulted in lower postoperative pain scores, and improved postoperative functional outcomes, although this was not a clinically significant difference. In addition, there were no significant differences in the rate of complications, revisions, or joint malreduction. LEVEL OF EVIDENCE: Level III, systematic review of Level I, II, and III studies.

The histopathological and molecular features of breast carcinoma with tumour budding-a systematic review and meta-analysis.

PURPOSE: Tumour budding (TB) is an adverse histological feature in many epithelial cancers. It is thought to represent epithelial-mesenchymal transition, a key step in the metastatic process. The significance of TB in breast carcinoma (BC) remains unclear. The aim of this study is to investigate the relationship between TB and other histological and molecular features of BC. METHODS: A systematic search was performed to identify studies that compared features of BC based on the presence or absence of high-grade TB. Dichotomous variables were pooled as odds ratios (OR) using the Der Simonian-Laird method. Quality assessment of the included studies was performed using the Newcastle-Ottawa scale (NOS). RESULTS: Seven studies with a total of 1040 patients (high-grade TB n = 519, 49.9%; low-grade/absent TB n = 521, 50.1%) were included. A moderate to high risk of bias was noted. The median NOS was 7 (range 6-8). High-grade TB was significantly associated with lymph node metastasis (OR 2.32, 95% c.i. 1.77 to 3.03, P < 0.001) and lymphovascular invasion (OR 3.08, 95% c.i. 2.13 to 4.47, P < 0.001). With regard to molecular subtypes, there was an increased likelihood of high-grade TB in oestrogen (OR 1.66, 95% c.i. 1.21 to 2.29, P = 0.002) and progesterone receptor-positive (OR 1.48, 95% c.i. 1.09 to 2.02, P = 0.01) tumours. In contrast, triple-negative breast cancer had a reduced incidence of high-grade TB (OR 0.46, 95% c.i. 0.30 to 0.72, P = 0.0006). CONCLUSION: High-grade TB is enriched in hormone receptor-positive BC and is associated with known adverse prognostic variables. TB may offer new insights into the metastatic process of BC.
