Differential attainment in higher surgical training: scoping pan-specialty spectra.

INTRODUCTION: This study aimed to evaluate differential attainment during higher surgical training (HST; all specialties) related to three ethnic cohorts: White UK (WUKG), Black and Minority Ethnic UK Graduates (BMEUKG), and International Medical Graduates (IMG). METHOD: Anonymised records of 266 HSTs (126 WUKG, 65 BMEUKG, 75 IMG; 7 years) in a single UK Statutory Education Body were examined. Primary effect measures were Annual Record of Competency Progression Outcome (ARCPO) and Fellowship of the Royal College of Surgeons (FRCS) pass. RESULTS: ARCPOs related to ethnicity and specialty were similar with the exception of general surgery (GS) trainees, four of whom received ARCPO 4 (GS 4.9% (75% BME; p=0.025) vs all other 0%). ARCPO 3 was commoner in women (22/76, (28.9%) than men 27/190 (14.2%), OR 2.46, p=0.006). FRCS pass rates (WUKG vs BMEUKG vs IMG) were 76.9%, 52.9% and 53.9% respectively (p=0.064) but unrelated to gender (M 70.4% vs F 64.3%). On multivariable analyses: ARCPO 3 was associated with Female gender and Maternity Leave (OR 8.05, p=0.001); FRCS pass with ethnicity (OR 0.21, p=0.028) and Hirsch Indices of ≥5 (OR 11.17, p=0.001). CONCLUSION: Differential attainment was plain with BMEUKG FRCS performance almost a third poorer than WUKG, and women twofold more likely to receive adverse ARCPOs, with return from statutory leave independently associated with training extension. Focused counter measures targeted at non-operative technical skills (including academic reach), Keeping in Touch, Return to Work, and re-induction programmed support are urgently needed for trainees at risk.

Trainee burnout: when does the fire start?

PURPOSE OF THE STUDY: Burnout is an increasingly recognised phenomenon in acute healthcare specialities and associated with depersonalisation, ill health and training programme attrition. This study aimed to quantify contributory physiological variables that may indicate stress in newly qualified doctors. STUDY DESIGN: Post Graduate Year 1 doctors (n=13, 7 f, 6 m) were fitted with a VivaLNK wellness device during four prior induction days, followed by their first 14 days work as qualified doctors. Minute-by-minute Heart Rate (HR), Respiratory Rate (RR), and Stress Index (SI) data were correlated with Maslach Burnout Inventories, Short Grit Scales (SGS) and clinical rota duties: Induction vs Normal Working-Day (NWD) versus On-call shift. RESULTS: In a total 125 recorded shift episodes, on comparing Induction versus NWD versus On-call shift work, no variation was observed in HR above baseline (25.47 vs 27.14 vs 24.34, p=0.240), RR above baseline (2.21 vs 1.86 vs 1.54, p=0.126) or SI (32.98 vs 38.02 vs 35.47, p=0.449). However, analysis of participant-specific temporal SIs correlated with shift-related clinical duties; that is, study participants who were most stressed during a NWD, were also more stressed during Induction (R2 0.442, p=0.026), and also during On-call shifts (R2 0.564, p=0.012). Higher SGS scores were inversely related to lower SIs (coefficient -32.52, 95% CI -45.881 to 19.154, p=0.001). CONCLUSION: Stress and burnout stimulus appear to start on day one of induction for susceptible PGY1 doctors, and continues into front-line clinical work irrespective of shift pattern. Short Grit Scale questionnaires appear an effective tool to facilitate targeted stress countermeasures.

Gongs galore: phaleristic study of the relative risk of a healing art related New Year Honour.

OBJECTIVES: To compare proportional representation of healthcare specialty workers, in receipt of New Year Honours (NYHs) and examine system bias. DESIGN: Observational study of UK honours system including comparative analysis of proportional representation of the UK medical workforce. PARTICIPANTS: Recipients of NYHs from 2010 to 2019. MAIN OUTCOME MEASURES: Absolute risk of receiving an NYH, related to medical specialty, gender and geographical region. Relative risk (RR) of receiving an NYH for services to healthcare related to specialty. RESULTS: 11 207 NYHs were bestowed, with 368 (3.3%) awarded to healthcare professionals: 212 (57.6%) women, 156 (42.4%) men. The RR of a healthcare professional receiving an NYH was 0.76 (95% CI 0.68 to 0.84, p<0.001) when compared with the remaining UK workforce. Doctors received most NYHs (n=181), with public health, clinical oncology and general medicine specialties most likely to be rewarded (RR 20.35 (95% CI 9.61 to 43.08, p<0.001), 8.43 (95% CI 2.70 to 26.30, p<0.001) and 8.22 (95% CI 6.22 to 10.86, p<0.001)), respectively; anaesthetists received fewest NYHs (RR 0.52 (95% CI 0.13 to 2.10), p=0.305). Men were more likely to receive NYHs than women (OR 0.44, 95% CI 0.36 to 0.54; p<0.001). Two hundred and fifty-four NYHs (69.0%) were bestowed on residents of England (60, 16.3% London), 49 (13.3%) Scotland (p=0.003), 39 (10.6%) Wales (p<0.001) and 26 (7.1%) Northern-Ireland (p<0.001). CONCLUSIONS: Relative risk of receiving an NYH varied over 150-fold by specialty, twofold by gender and threefold by geographical location. Public health physicians are perceived to be the pick of the parade.

Surgical curriculum concordance: requiem for the educational dream.

This study aimed to analyse the degree of relative variation in speciality-specific competencies required for Certification of Completion of Training (CCT) set by the UK Joint Committee for Surgical Training (JCST) 2021 curriculum. Regulatory body guidance related to operative and non-operative surgical skill competencies required for CCT were analysed and compared. Wide inter-speciality variation was demonstrated in the minimum number of logbook cases (median 815; range 54 to 2100), indexed operations (8; 5 to 24) and procedure-based assessments (35; 6 to 110). Academic competencies related to peer-reviewed publications, communications to learned societies and audits were aligned at zero, zero and three across specialities, respectively. Mandatory courses have been standardised with Advanced Trauma Life Support being the sole pre-requisite CCT for all. JCST certification guidelines have broadly standardised competency domains, yet large discrepancies persist regarding operative indicative numbers and assessments. This article serves as a definitive CCT guide regarding prevailing changes.

Strategic organisational skills predict surgical training success.

INTRODUCTION: Surgical career progression is determined by examination success and Annual Review of Competence Progression (ARCP) outcome, yet data on organisational skills are sparse. This study aimed to determine whether organisational skills related to Core Surgical Training (CST) outcome. Primary outcome measures include operative experience, publications, examination success (Membership of the Royal College of Surgeons or the Diploma in Otolaryngology-Head and Neck Surgery (MRCS/DO-HNS)) and ARCP outcome. METHODS: The study was conducted prospectively at three consecutive CST induction boot camps (2017-2019) providing clinical and simulation training for 125 trainees. Arrival time at course registration was the selected surrogate for organisational skills. Trainees were advised to arrive promptly at 8:45 for registration and that the course would start at 9:00. Trainee arrival times were grouped as follows: early (before 8:45), on time (8:45-8:59am) or late (after 9:00). Arrival times were compared with primary outcome measures. SETTING: Health Education and Improvement Wales' School of Surgery, UK. RESULTS: Median arrival time was 8:53 (range 7:55-10:03), with 29 trainees (23.2%) arriving early, 63 (50.4%) on-time and 33 (26.4%) late. Arrival time was associated with operative experience (early vs late; 206 vs 164 cases, p=0.012), publication (63.2% vs 18.5%, p=0.005), MRCS/DO-HNS success (44.8% vs 15.2%, p=0.029), ARCP outcome (86.2% vs 60.6% Outcome 1, p=0.053), but not National Training Number success (60.0% vs 53.3%, p=0.772). CONCLUSIONS: Better-prepared trainees achieved 25% more operative experience, were four-fold more likely to publish and pass MRCS, which aligned with consistent desirable ARCP outcome. Timely arrival at training events represents a skills-composite of travel planning and is a useful marker of strategic organisational skills.

Prognostic significance of competition ratios in surgical specialty training selection.

BACKGROUND: A competition ratio (CR) indicates the ratio of total applications for a training post when compared with numbers of specialty posts available. This study aimed to evaluate CRs' influence on National Training Number (NTN) selection in a single UK Statutory Education Body. METHODS: Consecutive core surgical trainees numbering 154 (105 men, 49 women; median years since graduation: four) were studied over a 6-year period. Annual specialty specific CRs were obtained from Health Education England's website, and primary outcome measure was UK NTN appointment. RESULTS: Overall NTN appointment was 45.5%. Median CR was 2.36; range Oral & Maxillofacial Surgery 0.70 (2020) to Neurosurgery 22.0 (2020). Multivariable analysis revealed that NTN success was associated with: CR (OR 0.46, p=0.003), a single scientific publication (OR 6.25, p=0.001), cohort year (2019, OR 12.65, p=0.003) and Universal Annual Review of Competence Progression Outcome 1 (OR 45.24, p<0.001). CRs predicted NTN appointment with a Youden index defined critical ratio of 4.42; 28.6% (n=8) versus 49.2% (n=62), p=0.018. CONCLUSION: CRs displayed 30-fold variation, with CRs below 4.42 associated with twofold better NTN promotion, but strong clinical competence and academic reach again emerged as the principal drivers of career advancement.

The Glasgow Microenvironment Score associates with prognosis and adjuvant chemotherapy response in colorectal cancer.

BACKGROUND: The Glasgow Microenvironment Score (GMS) combines peritumoural inflammation and tumour stroma percentage to assess interactions between tumour and microenvironment. This was previously demonstrated to associate with colorectal cancer (CRC) prognosis, and now requires validation and assessment of interactions with adjuvant therapy. METHODS: Two cohorts were utilised; 862 TNM I-III CRC validation cohort, and 2912 TNM II-III CRC adjuvant chemotherapy cohort (TransSCOT). Primary endpoints were disease-free survival (DFS) and relapse-free survival (RFS). Exploratory endpoint was adjuvant chemotherapy interaction. RESULTS: GMS independently associated with DFS (p = 0.001) and RFS (p < 0.001). GMS significantly stratified RFS for both low risk (GMS 0 v GMS 2: HR 3.24 95% CI 1.85-5.68, p < 0.001) and high-risk disease (GMS 0 v GMS 2: HR 2.18 95% CI 1.39-3.41, p = 0.001). In TransSCOT, chemotherapy type (pinteraction = 0.013), but not duration (p = 0.64) was dependent on GMS. Furthermore, GMS 0 significantly associated with improved DFS in patients receiving FOLFOX compared with CAPOX (HR 2.23 95% CI 1.19-4.16, p = 0.012). CONCLUSIONS: This study validates the GMS as a prognostic tool for patients with stage I-III colorectal cancer, independent of TNM, with the ability to stratify both low- and high-risk disease. Furthermore, GMS 0 could be employed to identify a subset of patients that benefit from FOLFOX over CAPOX.

Prognostic significance of serum inflammatory markers in esophageal cancer.

BACKGROUND: The aim of this study was to assess the relative prognostic value of biomarkers to measure the systemic inflammatory response (SIR) and potentially improve prognostic modeling in patients undergoing potentially curative surgery for esophageal adenocarcinoma (EC). METHODS: Consecutive 330 patients undergoing surgery for EC between 2004 and 2018 within a regional UK cancer network were identified. Serum measurements of haemoglobin, C-reactive protein, albumin, modified Glasgow Prognostic Score (mGPS), and differential neutrophil to lymphocyte ratio (NLR) were obtained before surgery, and correlated with histopathological factors and outcomes. Primary outcome measures were disease-free (DFS) and overall survival (OS). RESULTS: Of 330 OC patients, 294 underwent potentially curative esophagectomy. Univariable DFS analysis revealed pT, pN, pTNM stage (all p < 0.001), poor differentiation (p = 0.001), vascular invasion (p < 0.001), R1 status (p < 0.001), perioperative chemotherapy (p = 0.009), CRP (p = 0.010), mGPS (p = 0.011), and NLR (p < 0.001), were all associated with poor survival. Multivariable Cox regression analysis of DFS revealed only NLR [Hazard Ratio (HR) 3.63, 95% Confidence Interval (CI) 2.11-6.24, p < 0.001] retained significance. Multivariable Cox regression analysis of OS revealed similar findings: NLR [HR 2.66, (95% CI 1.58-4.50), p < 0.001]. CONCLUSION: NLR is an important SIR prognostic biomarker associated with DFS and OS in EC.

Egalitarianism in surgical training: let equity prevail.

This study aimed to quantify core surgical trainee (CST) differential attainment (DA) related to three cohorts; white UK graduate (White UKG) versus black and minority ethnic UKG (BME UKG) versus international medical graduates (IMGs). The primary outcome measures were annual review of competence progression (ARCP) outcome, intercollegiate Membership of the Royal College of Surgeons (iMRCS) examination pass and national training number (NTN) selection. Intercollegiate Surgical Curriculum Programme (ISCP) portfolios of 264 consecutive CSTs (2010-2017, 168 white UKG, 66 BME UKG, 30 IMG) from a single UK regional post graduate medical region (Wales) were examined. Data collected prospectively over an 8-year time period was analysed retrospectively. ARCP outcomes were similar irrespective of ethnicity or nationality (ARCP outcome 1, white UKG 60.7% vs BME UKG 62.1% vs IMG 53.3%, p=0.395). iMRCS pass rates for white UKG vs BME UKG vs IMG were 71.4% vs 71.2% vs 50.0% (p=0.042), respectively. NTN success rates for white UKG vs BME UKG vs IMG were 36.9% vs 36.4% vs 6.7% (p=0.023), respectively. On multivariable analysis, operative experience (OR 1.002, 95% CI 1.001 to 1.004, p=0.004), bootcamp attendance (OR 2.615, 95% CI 1.403 to 4.871, p=0.002), and UKG (OR 7.081, 95% CI 1.556 to 32.230, p=0.011), were associated with NTN appointment. Although outcomes related to BME DA were equitable, important DA variation was apparent among IMGs, with iMRCS pass 21.4% lower and NTN success sixfold less likely than UKG. Targeted counter measures are required to let equity prevail in UK CST programmes.

Targeting Wnt Signaling for the Treatment of Gastric Cancer.

The Wnt signaling pathway is evolutionarily conserved, regulating both embryonic development and maintaining adult tissue homeostasis. Wnt signaling controls several fundamental cell functions, including proliferation, differentiation, migration, and stemness. It therefore plays an important role in the epithelial homeostasis and regeneration of the gastrointestinal tract. Often, both hypo- or hyper-activation of the pathway due to genetic, epigenetic, or receptor/ligand alterations are seen in many solid cancers, such as breast, colorectal, gastric, and prostate. Gastric cancer (GC) is the fourth commonest cause of cancer worldwide and is the second leading cause of cancer-related death annually. Although the number of new diagnoses has declined over recent decades, prognosis remains poor, with only 15% surviving to five years. Geographical differences in clinicopathological features are also apparent, with epidemiological and genetic studies revealing GC to be a highly heterogeneous disease with phenotypic diversity as a result of etiological factors. The molecular heterogeneity associated with GC dictates that a single 'one size fits all' approach to management is unlikely to be successful. Wnt pathway dysregulation has been observed in approximately 50% of GC tumors and may offer a novel therapeutic target for patients who would otherwise have a poor outcome. This mini review will highlight some recent discoveries involving Wnt signaling in GC.

Relative Value of Adapted Novel Bibliometrics in Evaluating Surgical Academic Impact and Reach.

BACKGROUND: The Hirsch index, often used to assess research impact, suffers from questionable validity within the context of General Surgery, and consequently adapted bibliometrics and altmetrics have emerged, including the r-index, m-index, g-index and i10-index. This study aimed to assess the relative value of these novel bibliometrics in a single UK Deanery General Surgical Consultant cohort. METHOD: Five indices (h, r, m, g and i10) and altmetric scores (AS) were calculated for 151 general surgical consultants in a UK Deanery. Indices and AS were calculated from publication data via the Scopus search engine with assessment of construct validity and reliability. RESULTS: The median number of publications, h-index, r-index, m-index, g-index and i10-index were 13 (range 0-389), 5 (range 0-63), 5.2 (range 0-64.8), 0.33 (range 0-1.5), 10 (range 0-125) and 4 (range 0-245), respectively. Correlation coefficients of r-index, m-index, g-index and i10-index with h-index were 0.913 (p < 0.001), 0.716 (p < 0.001), 0.961 (p < 0.001) and 0.939 (p < 0.001), respectively. Significant variance was observed when the cohort was ranked by individual bibliometric measures; the median ranking shifts were: r-index - 2 (- 46 to + 23); m-index - 6.5 (- 53 to + 22); g-index - 0.5 (- 24 to + 13); and i10-index 0 (- 8 to + 11), respectively (p < 0.001). The median altmetric score and AS index were 0 (range 0-225.5) and 1 (range 0-10), respectively; AS index correlated strongly with h-index (correlation coefficient 0.390, p < 0.001). CONCLUSIONS: Adapted bibliometric indices appear to be equally valid measures of evaluating academic productivity, impact and reach.

Mode of presentation rather than the 'weekend effect' is a major determinant of in-hospital mortality.

BACKGROUND: The influence of patient demographics and mode of admission on the 'weekend effect' remains unclear. This study examins the relationship between day of admission, patient demographics, mode of presentation and survival. METHODS: Hospital admissions over a three-year period were studied. Patients with an inpatient stay less than 24 h and those who were discharged from the emergency department were excluded. In-hospital mortality was correlated with day of admission, age, gender and mode of presentation in a binary logistical regression analysis. RESULTS: There were 448,827 admissions, of which 350,648 (85.7%) occurred during a weekday. 256,777 (62.7%) were emergency presentations, which was closely related to a weekend admission (92.3% vs 57.8%, p < 0.001). There were 8099 deaths of which 6336 (78.2%) related to a weekday admission and 1736 (21.4%) related a weekend admission. Mortality for elective admissions was 78 (0.05%) compared to 8021 (3.12%), p < 0.001 in emergency admissions. Univariable regression analysis revealed a weekend admission (Odds Ratio (OR) 1.68 (95% confidence interval (CI) 1.60-1.78, p < 0.001) and emergency presentation (OR 63.02 (95%CI 50.42-78.77), p < 0.011) were associated with weekend mortality. On multivariable analysis the OR for weekend admission reduced to 1.07 (95%CI 1.01-1.13), p = 0.013 and the OR for emergency presentation increased to 76.68 (95%CI 61.40-96.00), p < 0.001. CONCLUSION: This study highlights that higher weekend mortality rates are a consequence of a lower proportion of elective admissions. Extending the working week to seven days might reduce weekend mortality without reducing the total number of deaths.

ERK and p38MAPK combine to improve survival in patients with BRAF mutant colorectal cancer.

BACKGROUND: In colorectal cancer (CRC), BRAF mutations influence tumour progression. In mismatch repair-deficient (dMMR) tumours, BRAF mutations are associated with a good prognosis, whereas in MMR-competent tumours, they are detrimental. The differential expression of the downstream MAPK pathway members, which are constitutively activated in BRAF mutant patients, may account for these differences. METHODS: Phosphorylation of ERK, p38MAPK and JNK was assessed by immunohistochemistry, utilising CRC tissue microarrays. A discovery cohort (n = 187) and a validation cohort (n = 801) were analysed for associations with BRAF mutations, clinicopathological characteristics and cancer-specific survival (CSS). RESULTS: In 801 CRC patients, nuclear ERK phosphorylation (HR 0.65 95% CI 0.48-0.88, p = 0.004) and the combined nuclear pERK/p-p38 score (HR 0.61 95% CI 0.45-0.82, p = 0.001) were independently associated with CSS, and were further associated with increased BRAF mutations (p = 0.003 and p = 0.002). When stratified for BRAF status, only MMR-competent patients harbouring the mutation and a strong combined nuclear pERK/p-p38 score (HR 0.49 95% CI 0.27-0.89, p = 0.016) demonstrated improved CSS. This improvement in CSS was specific to stage III CRC (HR 0.25 95% CI 0.10-0.64, p = 0.002). CONCLUSIONS: MMR-competent stage III tumours harbouring BRAF mutations have an improved prognosis when strong nuclear phosphorylation of both ERK and p38MAPK is present.

Altmetric Versus Bibliometric Perspective Regarding Publication Impact and Force.

BACKGROUND: Bibliometric and Altmetric analyses highlight key publications, which have been considered to be the most influential in their field. The hypothesis was that highly cited articles would correlate positively with levels of evidence and Altmetric scores (AS) and rank. METHODS: Surgery as a search term was entered into Thomson Reuter's Web of Science database to identify all English-language full articles. The 100 most cited articles were analysed by topic, journal, author, year, institution, and AS. RESULTS: By bibliometric criteria, eligible articles numbered 286,122 and the median (range) citation number was 574 (446-5746). The most cited article (Dindo et al.) classified surgical complications by severity score (5746 citations). Annals of Surgery published most articles and received most citations (26,457). The country and year with most publications were the USA (n = 50) and 1999 (n = 11). By Altmetric criteria, the article with the highest AS was by Bigelow et al. (AS = 53, hypothermia's role in cardiac surgery); Annals of Surgery published most articles, and the country and year with most publications were USA (n = 4) and 2007 (n = 3). Level-1-evidence articles numbered 13, but no correlation was found between evidence level and citation number (SCC 0.094, p = 0.352) or AS (SCC = 0.149, p = 0.244). Median AS was 0 (0-53), and in articles published after the year 2000, AS was associated with citation number (r = 0.461, p = 0.001) and citation rate index (r = 0.455, p = 0.002). AS was not associated with journal impact factor (r = 0.160, p = 0.118). CONCLUSION: Bibliometric and Altmetric analyses provide important but different perspectives regarding article impact, which are unrelated to evidence level.

The Pretreatment Systemic Inflammatory Response is an Important Determinant of Poor Pathologic Response for Patients Undergoing Neoadjuvant Therapy for Rectal Cancer.

BACKGROUND: Not all patients respond equally to neoadjuvant chemoradiotherapy (nCRT), with subsequent effects on survival. The systemic inflammatory response has been shown to predict long-term outcomes in colorectal cancer. The current study examined the association between systemic inflammation and nCRT in patients with rectal cancer. METHODS: Between 1999 and 2010, patients who underwent nCRT were identified. Serum measurements of hemoglobin, C-reactive protein, albumin, modified Glasgow prognostic score (mGPS), and differential white cell counts were obtained before and after nCRT. The Rödel scoring system measured pathologic tumor regression, and magnetic resonance imaging and computed tomography determined radiologic staging. RESULTS: The study included 79 patients. Of these patients, 37% were radiologically downstaged, and 44% were categorized as showing a good pathologic response (Rödel scores 3 and 4). As a validated measure of the systemic inflammatory response, mGPS (P = 0.022) was associated with a poor pathologic response to nCRT. A radiologic response was associated with a good pathologic response to treatment (P = 0.003). A binary logistic regression model identified mGPS (odds ratio [OR] 0.27; 95% confidence interval [CI] 0.07-0.96; P = 0.043) and radiologic response (OR 0.43; 95% CI 0.18-0.99; P = 0.048) as strong independent predictors of a pathologic response to treatment. CONCLUSION: The current study showed that a systemic inflammatory response before nCRT is associated with a poor pathologic response. Further study in a prospective controlled trial setting is warranted.

Mismatch repair status in patients with primary operable colorectal cancer: associations with the local and systemic tumour environment.

BACKGROUND: Mismatch repair-deficient (dMMR) colorectal cancer (CRC) is associated with a conspicuous local immune infiltrate; however, its relationship with systemic inflammatory responses remains to be determined. The present study aims to examine the relationships and prognostic value of assessment of the local and systemic environment in the context of MMR status in patients with CRC. METHODS: The relationship between MMR status, determined using immunohistochemistry, and the local inflammatory cell infiltrate, differential white cell count, neutrophil : platelet score (NPS), neutrophil : lymphocyte ratio and modified Glasgow Prognostic Score (mGPS), and cancer-specific survival was examined in 228 patients undergoing resection of stage I-III CRC. RESULTS: Thirty-five patients (15%) had dMMR CRC. Mismatch repair deficiency was associated with a higher density of CD3(+), CD8(+) and CD45R0(+) T lymphocytes within the cancer cell nests and an elevated mGPS (mGPS2: 23% vs 9%, P=0.007) and NPS (NPS2: 19% vs 3%, P=0.001). CD3(+) density (P<0.001), mGPS (P=0.01) and NPS (P=0.042) were associated with survival independent of MMR status (P=0.367) and stratified 5-year survival of patients with MMR-competent CRC from 94% to 67%, 83% to 46% and 78% to 60% respectively. CONCLUSIONS: Mismatch repair deficiency was associated with local and systemic environments, and in comparison with their assessment, dMMR had relatively poor prognostic value in patients with primary operable CRC. In addition to MMR status, local and systemic inflammatory responses should be assessed in these patients.

Long-Term Follow-Up of Patients Undergoing Resection of TNM Stage I Colorectal Cancer: An Analysis of Tumour and Host Determinants of Outcome.

BACKGROUND: Screening for colorectal cancer improves cancer-specific survival (CSS) through the detection of early-stage disease; however, its impact on overall survival (OS) is unclear. The present study examined tumour and host determinants of outcome in TNM Stage I disease. METHODS: All patients with pathologically confirmed TNM Stage I disease across 4 hospitals in the North of Glasgow between 2000 and 2008 were included. The preoperative modified Glasgow Prognostic Score (mGPS) was used as a marker of the host systemic inflammatory response (SIR). RESULTS: There were 191 patients identified, 105 (55 %) were males, 91 (48 %) were over the age of 75 years and 7 (4 %) patients underwent an emergency operation. In those with a preoperative CRP result (n = 150), 35 (24 %) patients had evidence of an elevated mGPS. Median follow-up of survivors was 116 months (minimum 72 months) during which 88 (46 %) patients died; 7 (8 %) had postoperative deaths, 15 (17 %) had cancer-related deaths and 66 (75 %) had non-cancer-related deaths. 5-year CSS was 95 % and OS was 76 %. On univariate analysis, advancing age (p < 0.001), emergency presentation (p = 0.008), and an elevated mGPS (p = 0.012) were associated with reduced OS. On multivariate analysis, only age (HR = 3.611, 95 % CI 2.049-6.365, p < 0.001) and the presence of an elevated mGPS (HR = 2.173, 95 % CI 1.204-3.921, p = 0.010) retained significance. CONCLUSIONS: In patients undergoing resection for TNM Stage I colorectal cancer, an elevated mGPS was an objective independent marker of poorer OS. These patients may benefit from a targeted intervention.
