The longitudinal impact of division-wide implementation of an enhanced recovery after thoracic surgery programme.

OBJECTIVES: Data regarding enhanced recovery after thoracic surgery (ERATS) are sparse and inconsistent. This study aims to evaluate the effects of implementing an enhanced ERATS programme on postoperative outcomes, patient experience and quality of life (QOL). METHODS: We conducted a prospective, longitudinal study evaluating 9 months before (pre-ERATS) and 9 months after (post-ERATS) a 3-month implementation of an ERATS programme in a single academic tertiary care centre. All patients undergoing major thoracic surgeries were included. The primary outcomes included length of stay (LOS), adverse events (AEs), 6-min walk test scores at 4 weeks, 30-day emergency room visits (without admission) and 30-day readmissions. The process-of-care outcomes included time to 'out-of-bed', independent ambulation, successful fluid intake, last chest tube removal and removal of urinary catheter. Perioperative anaesthesia-related outcomes were examined as well as patient experience and QOL scores. RESULTS: The pre-ERATS group (n = 352 patients) and post-ERATS group (n = 352) demonstrated no differences in demographics. Post-ERATS patients had improved LOS (4.7 vs 6.2 days, P < 0.02), 6-min walk test scores (402 vs 371 m, P < 0.05) and 30-day emergency room visits (13.7% vs 21.6%, P = 0.03) with no differences in AEs and 30-day readmissions. Patients experienced shorter mean time to 'out-of-bed', independent ambulation, successful fluid intake, last chest tube removal and urinary catheter removal. There were no differences in postoperative analgesia administration, patient satisfaction and QOL scores. CONCLUSIONS: ERATS implementation was associated with improved LOS, expedited feeding, ambulation and chest tube removal, without increasing AEs or readmissions, while maintaining a high level of patient satisfaction and QOL.

The Predictive Value of Inflammatory Biomarkers in Esophageal Anastomotic Leaks.

BACKGROUND: This study investigated the role of the neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak (AL) after esophagectomy for esophageal adenocarcinoma. METHODS: This is a retrospective analysis of a prospectively collected database from the McGill University Health Center. Included were all patients with esophageal adenocarcinoma who underwent esophagectomy between 2005 and 2016. Patients with chronic infections, concurrent active malignancies, and autoimmune conditions were excluded. NLR values were obtained on postoperative days (POD) 0, 1, 2, and 3. Receiver operating characteristic curve study and multivariable logistic analysis were conducted to evaluate the diagnostic value of NLR. RESULTS: The study included 330 patients, and AL developed in 16%. Mean NLR values on POD1, 2, and 3 were higher in patients with leaks (20 vs 14 on POD1, P < .001; 20 vs 12 on POD2, P < .001; and 19 vs 10 on POD3, P < .001). The NLR value on POD3 was associated with an area under the curve of 70% and a negative predictive value of 92.4%. Multivariable analyses identified higher American Society of Anesthesiologists Physical Status Classification, increasing NLR trend (between POD1 and POD3), POD1 NLR, POD2 NLR, and POD3 NLR as independent factors associated with AL. CONCLUSIONS: Patients who developed AL demonstrate higher mean NLR values in the early postoperative period with rising trends. Conversely a low NLR is associated with a high negative predictive value for AL. This simple metric allows risk stratification that may guide treatment decisions in esophagectomy patients.

Knowledge of symptoms, time to presentation and barriers to medical help-seeking among Omani women diagnosed with breast cancer: a cross-sectional study.

OBJECTIVE: To identify knowledge of breast cancer (BC) symptoms, time taken to consult a doctor and factors contributing to delays in medical help-seeking. DESIGN: A cross-sectional study of Omani women diagnosed with BC. SETTING: The two main teaching hospitals in Oman: Royal Hospital and Sultan Qaboos University Hospital. PARTICIPANTS: Adult Omani women recently diagnosed with BC. TOOLS: The Breast Module of the Cancer Awareness Measure and the International Cancer Benchmarking Partnership questionnaire were used to collect data. RESULTS: A total of 300 women with BC participated (response rate: 91.0%). The mean age at diagnosis was 43.0±12.50 years and 33.5% were diagnosed at stage III or IV. Although most women (74.4%) recognised breast/armpit lumps to be a symptom of BC, less than half identified other symptoms, including breast/armpit pain (44.0%), changes in the position of the nipple (36.2%), redness (31.7%), fatigue (26.3%), weight loss (23.4%) and loss of appetite (20.8%). While most (91.6%) were aware that BC could be cured if detected early, only 66.4% sought medical help within a month of developing symptoms. Initial responses to symptoms included informing husbands (40.2%) or family members (36.5%). Barriers to seeking medical help included feeling scared (68.9%) and worried about what the doctor might find (62.8%). Highly educated women were more likely to recognise the following as BC symptoms: changes in nipple position (OR: 0.16, 95% CI 0.03 to 0.81), breast pain (OR: 0.10, 95% CI 0.01 to 0.86) and unexplained weight loss (OR: 0.18, 95% CI 0.04 to 0.88) (all p<0.05). CONCLUSIONS: Although many Omani women with BC were aware of the importance of early diagnosis, most demonstrated inadequate knowledge of symptoms, did not prioritise seeking medical help and reported emotional barriers to help-seeking. More educational measures are needed to improve symptom recognition and address help-seeking barriers to minimise delays in diagnosis.

Prognostic value of neutrophil to lymphocyte ratio in lung metastasectomy for colorectal cancer.

OBJECTIVES: Neutrophil to lymphocyte ratio (NLR) has been shown to be a promising biomarker in several cancers. Prognostic biomarkers are still needed to define good candidates for lung metastasectomy for colorectal cancer. We aimed to evaluate the role of NLR. METHODS: Data from 574 patients who underwent lung metastasectomy for colorectal cancer in 3 departments of thoracic surgery from 2004 to 2014 were retrospectively reviewed. Overall survival (OS) and the time to pulmonary recurrence (TTPR) were the main end points. RESULTS: Correlations between NLR and OS (R2 = 0.53), and NLR and TTPR (R2 = 0.389) were significant (P < 0.0001 for both), with corresponding Pearson R of -0.728 (P < 0.0001) and -0.624 (P < 0.0001), respectively. A receiver operating characteristic curve analysis highlighted an NLR cut-off value of 4.05 as the best predictor of OS and TTPR. NLR ≤4.05 was observed in 238 patients (41.4%). In the univariable analysis, the median OS was 117 months for patients with NLR ≤4.05 and decreased to 40 months for patients with NLR >4.05 (P < 0.0001). The median TTPR reached 52 months in case of NLR ≤4.05 and decreased to 12 months in patients with NLR >4.05. In the multivariable analysis, NLR ≤4.05 remained an independent favourable prognostic factor on both OS [hazard ratio [HR] 0.29, 95% confidence interval (CI) 0.167-0.503; P < 0.0001] and TTPR (HR 0.346, 95% CI 0.221-0.54; P < 0.0001). Significant correlations between NLR >4.05 and KRAS (Cramer's V = 0.241, P < 0.0001) and BRAF (Cramer's V = 0.153, P = 0.003) mutations were observed. CONCLUSIONS: NLR is a simple and powerful predictor of outcomes in patients undergoing pulmonary metastasectomy for colorectal cancer.
