ABSTRACT

AIM: Advanced stage presentation of colorectal cancer is associated with poorer survival outcomes, particularly among young adults. This study aimed to determine whether demographic risk factors for advanced stage presentation differed between young and older adults. METHOD: Individual-level data on all incident colorectal cancers in people aged 20 years and above were extracted from the National Cancer Registration and Analysis Service database for the years 2012 to 2015. Patients were divided into two cohorts: young-onset colorectal cancer (YOCC) if aged 20-49 years and older-onset colorectal cancer (OOCC) if aged 50 years and above. Logistic regression was used to identify risk factors for advanced stage presentation, defined as TNM Stage III or IV, in each cohort. RESULTS: There were 7075 (5.2%) patients in the YOCC cohort and 128 345 (94.8%) patients in the OOCC cohort. Tumours in the YOCC cohort were more likely to be at an advanced stage (67.2% vs 55.3%, P < 0.001) and located distally (63.7% vs 55.4%, P < 0.001). No demographic factor was consistently associated with advanced stage presentation in the YOCC cohort. Among the OOCC cohort, increased social deprivation [OR (Index of Multiple Deprivation quintile 5 vs 1) = 1.11 (95% CI 1.07-1.16), P < 0.001], Black/Black British ethnicity [OR (baseline White) = 1.25 (95% CI 1.11-1.40), P < 0.001] and residence in the East Midlands [OR (baseline London) = 1.11 (95% CI 1.04-1.17), P = 0.001] were associated with advanced stage presentation. CONCLUSION: Demographic factors associated with advanced disease were influenced by age. The effects of social deprivation and ethnicity were only observed in older adults and mirror trends in screening uptake. Targeted interventions for high-risk groups are warranted.

ABSTRACT

BACKGROUND: Evidence is emerging that the incidence of colorectal cancer is increasing in young adults, but the descriptive epidemiology required to better understand these trends is currently lacking. METHODS: A population-based cohort study was carried out including all adults aged 20-49 years diagnosed with colorectal cancer in England between 1974 and 2015. Data were extracted from the National Cancer Registration and Analysis Service database using ICD-9/10 codes for colorectal cancer. Temporal trends in age-specific incidence rates according to sex, anatomical subsite, index of multiple deprivation quintile and geographical region were analysed using Joinpoint regression. RESULTS: A total of 56 134 new diagnoses of colorectal cancer were analysed. The most sustained increase in incidence rate was in the group aged 20-29 years, which was mainly driven by a rise in distal tumours. The magnitude of incident rate increases was similar in both sexes and across Index of Multiple Deprivation quintiles, although the most pronounced increases in incidence occurred in the southern regions of England. CONCLUSION: Colorectal cancer should no longer be considered a disease of older people. Changes in incidence rates should be used to inform future screening policy, preventative strategies and research agendas, as well as increasing public understanding that younger people need to be aware of the symptoms of colorectal cancer.


ANTECEDENTES: Están apareciendo evidencias de que la incidencia del cáncer colorrectal (colorectal cancer, CRC) está aumentando en adultos jóvenes, pero se carece de la epidemiología descriptiva necesaria para comprender mejor estas tendencias. MÉTODOS: Se realizó un estudio de cohortes de base poblacional de todos los adultos de 20 a 49 años diagnosticados de CRC en Inglaterra entre 1974 y 2015. Los datos se extrajeron de la base de datos NCRAS utilizando los códigos ICD9/10 para el CRC. Las tendencias temporales en las tasas de incidencia específicas por edad (incidence rates, IR) según el sexo, la localización anatómica, el quintil del índice de privación múltiple (index of multiple deprivation, IMD) y la región geográfica se analizaron mediante un modelo de regresión joinpoint. RESULTADOS: Se analizaron un total de 56.134 nuevos diagnósticos de CRC. El aumento más sostenido en la IR se produjo en el grupo de edad de 20 a 29 años, principalmente a expensas de un incremento de los tumores distales. La magnitud de los aumentos de IR fue similar en ambos sexos y en los quintiles del IMD, aunque los aumentos más pronunciados en la incidencia se registraron en las regiones del sur de Inglaterra. CONCLUSIÓN: El CRC ya no debe ser considerado una enfermedad de las personas mayores: los cambios en las tasas de incidencia deberán tenerse en cuenta en las futuras políticas de cribado, en las estrategias preventivas y en los proyectos de investigación, así como para aumentar la toma de conciencia de la población de que las personas más jóvenes deben estar al corriente de los síntomas del CRC.

ABSTRACT

Recent studies suggest that the treatment response and survival from head and neck tumours can be stratified according to biomarker status, particularly human papillomavirus (HPV) status and p16 expression, but the evidence for predictive biomarkers in anal squamous cell carcinoma (ASCC) remains limited. The aim of this study was to determine which biomarkers were associated with locoregional recurrence (LRR), overall survival and disease-free survival (DFS) in ASCC. A systematic search was undertaken of the MEDLINE, Embase, Cochrane Library, CINAHL and Web of Science databases using validated terms for ASCC, biomarkers and prognosis. Biomarkers were included in the meta-analysis if they were reported by at least four studies and provided sufficient data to permit the calculation of survival effect estimates. HPV status, p16, p53 and epidermal growth factor receptor (EGFR) met the inclusion criteria for meta-analysis and were reported by 17 retrospective cohort studies describing 1635 patients. When compared with HPV-negative tumours, HPV-positive tumours were associated with reduced LRR (pooled hazard ratio = 0.27 [95% confidence interval 0.16-0.48]; P < 0.001), improved overall survival (hazard ratio =0.26 [0.12-0.59]; P = 0.001) and DFS (hazard ratio = 0.33 [0.16-0.70]; P = 0.003). Likewise, p16-positive tumours were associated with reduced LRR (hazard ratio = 0.26 [0.13-0.52]; P < 0.001), improved overall survival (hazard ratio = 0.44 [0.24-0.81]; P = 0.009) and DFS (hazard ratio = 0.44 [0.23-0.83]; P = 0.012) when compared with p16-negative tumours. HPV-positive/p16-positive tumours had improved overall survival when compared with HPV-negative/p16-negative tumours (hazard ratio = 0.27 [0.15-0.48], P < 0.001), but not HPV-negative/p16-positive tumours (hazard ratio = 0.64 [0.21-1.90]; P = 0.421). p53 mutation was associated with worse DFS (hazard ratio = 1.63 [1.33-2.01]; P = 0.003). There was no association between EGFR status and any survival outcome. HPV status, p16 and p53 expression are of prognostic utility in ASCC. Future studies should prospectively validate these findings with a view to conducting subsequent randomised controlled trials where patients are stratified according to biomarker status and randomised to different treatment regimens.

ABSTRACT

AIM: Total mesorectal excision remains the cornerstone of treatment for rectal cancer. Significant morbidity means local excision may be more appropriate in selected patients. Adjuvant therapy reduces local recurrence and improves survival; however, there is a paucity of data on its impact following local excision, which this systematic review aims to address. METHODS: A systematic search of the MEDLINE, Embase and Cochrane databases using validated terms for rectal cancer, adjuvant therapy and local excision was performed. Included studies focused on local excision with adjuvant therapy for adenocarcinoma of the rectum. Primary outcome measures were local recurrence, survival and morbidity. Studies providing neoadjuvant therapy or local excision alone were excluded. RESULTS: Twenty-two studies described 804 patients. Indications for local excision included favourable histology, patient choice and comorbidities. T1, T2 and T3 tumours accounted for 35.1%, 58.0% and 6.9% of cases, respectively. The most frequent local excision technique was transanal excision (77.7%). Adjuvant therapy included long-course chemoradiation or radiotherapy. Median follow-up was 51 months (range 1-165). The pooled local recurrence was 5.8% (95% CI 3.0-9.5) for pT1, 13.8% (95% CI 10.1-17.9) for pT2 and 33.7% (95% CI 19.2-50.1) for pT3 tumours. The overall median disease-free survival was 88% (range 50%-100%) with a pooled overall morbidity of 15.1% (95% CI 11.0-18.7). CONCLUSIONS: This area remains highly relevant to modern clinical practice. The data suggest that local excision followed by adjuvant therapy can achieve acceptable long-term outcomes in high-risk pT1 tumours, but not in T2 tumours and above in whom radical surgery should be offered.

ABSTRACT

INTRODUCTION: Favourable short-term results, with respect to less postoperative pain and earlier return to physical activity, have been demonstrated with laparoscopic totally extraperitoneal (TEP) hernia repair compared with open mesh repair. However, there is limited data regarding long-term results. PATIENTS AND METHODS: The study cohort consisted of 275 consecutive patients undergoing TEP repair between 1996 and 2002. Patient demographics, details of surgery, postoperative complications, recurrence and chronic pain were collected from patient records and from a prospective database. All patients were seen at 6 weeks and then annually for 5 years following surgery. RESULTS: A total of 430 repairs were performed in the 275 patients (median age, 56 years; range, 20-94 years; men, 97.5%). Bilateral repair was performed in 168 patients (61.1%) and recurrent hernia repair in 79 patients (28.7%). Two patients were converted to an open procedure. Five-year follow-up was achieved in 72% of patients. Eleven patients (4%) died during the follow-up period due to unrelated causes. Hernia recurrence rate at 5 years was 1.1% per patient (three repairs). Recurrences were noted at 7 months, 2 years and 4 years following surgery. Chronic groin pain was reported by 21 patients (7.6%), seven of whom required referral to the pain team. CONCLUSIONS: TEP hernia repair is associated with a recurrence rate of 1% at 5 years in this series. Chronic groin symptoms are also acceptably few. This recurrence rate following TEP repair compares extremely favourably with open mesh repair, particularly as it includes a high proportion of recurrent repairs. As well as the proven early benefits, TEP repair can be considered a safe and durable procedure with excellent long-term results.
