Retrospective analysis of geriatric major trauma patients admitted in the shock room of a Swiss academic hospital : characteristics and prognosis

L'espérance de vie accrue expose un grand nombre de personnes âgées à des accidents graves, augmentant ainsi le nombre de cas de traumatismes majeurs en gériatrie. Le but de notre étude est de déterminer le profil des patients âgés subissant un traumatisme majeur et les facteurs contributifs prédisant la mortalité dans ce groupe de patients spécifique, par rapport à la population plus jeune. Une analyse rétrospective de 1051 patients avec un traumatisme majeur admis sur dix ans dans un centre de traumatologie de niveau 1 a été réalisée. Les données recueillies sont les suivantes: histoire, nature et type de traumatisme; l'âge et le sexe; signes vitaux à l'admission; Score de gravité des blessures; indice de choc; comorbidités; diathèse de coagulation; schémas des blessures; mesures d'urgence prises; diagnostic principal; mortalité et la durée du séjour à l'hôpital et en unité de soins intensifs. Les patients gériatriques admis pour un traumatisme majeur ont un taux de mortalité presque quatre fois plus élevé (47%) que leurs homologues plus jeunes (14%) avec le même ISS (index severity score). Selon l'analyse de régression statistique, la thérapie anti-plaquettaire (OR 3.21), le score NACA (National Advisory Committee for Aeronautics) (OR 2.23), le GCS (OR 0.83), l'ISS (OR 1.07) et l'âge (OR 1.06) sont les principaux facteurs prédictifs de mortalité. -- Increased life expectancy exposes a great number of elderly people to serious accidents, thus increasing the amount of major geriatric trauma cases. The aim of our study was to determine the profile of elderly patients undergoing major trauma, and the contributing factors predicting mortality in this specific patient group, compared to the younger population. Retrospective analysis of 1051 patients with major trauma admitted over ten years in a Level-1 trauma œnter was performed. Data collected were: history, nature and type of trauma; age and sex; vital signs on admission; injury severity score; shock index; comorbidities; coagulation diathesis; injury patterns; emergency measures taken; main diagnosis; mortality; and length of hospital and intensive care unit (ICU) stay. Ceriatric patients admitted for major trauma have a mortality rate almost four times greater (47%) than their younger counterparts (14%) with the same ISS. According to statistical regression analysis, anti-platelet therapy (OR 3.21), NACA (National Advisory Committee for Aeronautics) score (OR 2.23), ces (OR 0.83), ISS (OR 1.07) and age (OR 1.06) are the main factors predicting mortality. Conclusion: Ceriatric major trauma patients admitted to our trauma resuscitation area have a high mortality rate. Age, CCS, ISS and NACA scores as well as anti-platelet therapy are the main factors predicting mortality

Post-Operative Functional Outcomes in Early Age Onset Rectal Cancer

Background: Impairment of bowel, urogenital and fertility-related function in patients treated for rectal cancer is common. While the rate of rectal cancer in the young (<50 years) is rising, there is little data on functional outcomes in this group. Methods: The REACCT international collaborative database was reviewed and data on eligible patients analysed. Inclusion criteria comprised patients with a histologically confirmed rectal cancer, <50 years of age at time of diagnosis and with documented follow-up including functional outcomes. Results: A total of 1428 (n=1428) patients met the eligibility criteria and were included in the final analysis. Metastatic disease was present at diagnosis in 13%. Of these, 40% received neoadjuvant therapy and 50% adjuvant chemotherapy. The incidence of post-operative major morbidity was 10%. A defunctioning stoma was placed for 621 patients (43%); 534 of these proceeded to elective restoration of bowel continuity. The median follow-up time was 42 months. Of this cohort, a total of 415 (29%) reported persistent impairment of functional outcomes, the most frequent of which was bowel dysfunction (16%), followed by bladder dysfunction (7%), sexual dysfunction (4.5%) and infertility (1%). Conclusion: A substantial proportion of patients with early-onset rectal cancer who undergo surgery report persistent impairment of functional status. Patients should be involved in the discussion regarding their treatment options and potential impact on quality of life. Functional outcomes should be routinely recorded as part of follow up alongside oncological parameters

Predictive Factors and Risk Model for Positive Circumferential Resection Margin Rate after Transanal Total Mesorectal Excision in 2653 Patients with Rectal Cancer

The aim of this study was to determine the incidence of, and preoperative risk factors for, positive circumferential resection margin (CRM) after transanal total mesorectal excision (TaTME). Background: TaTME has the potential to further reduce the rate of positive CRM for patients with low rectal cancer, thereby improving oncological outcome. Methods: A prospective registry-based study including all cases recorded on the international TaTME registry between July 2014 and January 2018 was performed. Endpoints were the incidence of, and predictive factors for, positive CRM. Univariate and multivariate logistic regressions were performed, and factors for positive CRM were then assessed by formulating a predictive model. Results: In total, 2653 patients undergoing TaTME for rectal cancer were included. The incidence of positive CRM was 107 (4.0%). In multivariate logistic regression analysis, a positive CRM after TaTME was significantly associated with tumors located up to 1 cm from the anorectal junction, anterior tumors, cT4 tumors, extra-mural venous invasion (EMVI), and threatened or involved CRM on baseline MRI (odds ratios 2.09, 1.66, 1.93, 1.94, and 1.72, respectively). The predictive model showed adequate discrimination (area under the receiver-operating characteristic curve >0.70), and predicted a 28% risk of positive CRM if all risk factors were present. Conclusion: Five preoperative tumor-related characteristics had an adverse effect on CRM involvement after TaTME. The predicted risk of positive CRM after TaTME for a specific patient can be calculated preoperatively with the proposed model and may help guide patient selection for optimal treatment and enhance a tailored treatment approach to further optimize oncological outcomes

Impact of microsatellite status in early-onset colonic cancer

Background: The molecular profile of early-onset colonic cancer is undefined. This study evaluated clinicopathological features and oncological outcomes of young patients with colonic cancer according to microsatellite status. Methods: Anonymized data from an international collaboration were analysed. Criteria for inclusion were patients younger than 50 years diagnosed with stage I-III colonic cancer that was surgically resected. Clinicopathological features, microsatellite status, and disease-specific outcomes were evaluated. Results: A total of 650 patients fulfilled the criteria for inclusion. Microsatellite instability (MSI) was identified in 170 (26.2 per cent), whereas 480 had microsatellite-stable (MSS) tumours (relative risk of MSI 2.5 compared with older patients). MSI was associated with a family history of colorectal cancer and lesions in the proximal colon. The proportions with pathological node-positive disease (45.9 versus 45.6 per cent; P = 1.000) and tumour budding (20.3 versus 20.5 per cent; P = 1.000) were similar in the two groups. Patients with MSI tumours were more likely to have BRAF (22.5 versus 6.9 per cent; P < 0.001) and KRAS (40.0 versus 24.2 per cent; P = 0.006) mutations, and a hereditary cancer syndrome (30.0 versus 5.0 per cent; P < 0.001; relative risk 6). Five-year disease-free survival rates in the MSI group were 95.0, 92.0, and 80.0 per cent for patients with stage I, II, and III tumours, compared with 88.0, 88.0, and 65.0 per cent in the MSS group (P = 0.753, P = 0.487, and P = 0.105 respectively). Conclusion: Patients with early-onset colonic cancer have a high risk of MSI and defined genetic conditions. Those with MSI tumours have more adverse pathology (budding, KRAS/BRAF mutations, and nodal metastases) than older patients with MSI cancers

La défense sociale et la nouvelle pénologie comme outils d'analyse de la conception du libéré conditionnel dans la législation belge (1888-2006)

Importance The incidence of early-onset colorectal cancer (younger than 50 years) is rising globally, the reasons for which are unclear. It appears to represent a unique disease process with different clinical, pathological, and molecular characteristics compared with late-onset colorectal cancer. Data on oncological outcomes are limited, and sensitivity to conventional neoadjuvant and adjuvant therapy regimens appear to be unknown. The purpose of this review is to summarize the available literature on early-onset colorectal cancer. Observations Within the next decade, it is estimated that 1 in 10 colon cancers and 1 in 4 rectal cancers will be diagnosed in adults younger than 50 years. Potential risk factors include a Westernized diet, obesity, antibiotic usage, and alterations in the gut microbiome. Although genetic predisposition plays a role, most cases are sporadic. The full spectrum of germline and somatic sequence variations implicated remains unknown. Younger patients typically present with descending colonic or rectal cancer, advanced disease stage, and unfavorable histopathological features. Despite being more likely to receive neoadjuvant and adjuvant therapy, patients with early-onset disease demonstrate comparable oncological outcomes with their older counterparts. Conclusions and Relevance The clinicopathological features, underlying molecular profiles, and drivers of early-onset colorectal cancer differ from those of late-onset disease. Standardized, age-specific preventive, screening, diagnostic, and therapeutic strategies are required to optimize outcomes
