Colonoscopy is a frequently used procedure in our environment for the diagnosis, treatment and even prevention of colorectal cancer. Despite being a routine procedure, it is not exempt from possible ...complications. Bleeding and perforation are the main ones, with splenic rupture being extremely infrequent as well as one of the most serious complications derived from performing a colonoscopy. We present a patient with splenic rupture secondary to colorectal cancer screening colonoscopy who required urgent surgery for acute hemorrhagic shock.
Abstract
Background
Bilobar liver metastases from colorectal cancer pose a challenge for obtaining a satisfactory oncological outcome with an adequate future liver remnant. This study aimed to assess ...the clinical and pathological determinants of overall survival and recurrence-free survival among patients undergoing surgical clearance of bilobar liver metastases from colorectal cancer.
Methods
A retrospective international multicentre study of patients who underwent surgery for bilobar liver metastases from colorectal cancer between January 2012 and December 2018 was conducted. Overall survival and recurrence-free survival at 1, 2, 3 and 5 years after surgery were the primary outcomes evaluated. The secondary outcomes were duration of postoperative hospital stay, and 90-day major morbidity and mortality rates. A prognostic nomogram was developed using covariates selected from a Cox proportional hazards regression model, and internally validated using a 3:1 random partition into derivation and validation cohorts.
Results
A total of 1236 patients were included from 70 centres. The majority (88 per cent) of the patients had synchronous liver metastases. Overall survival at 1, 2, 3 and 5 years was 86.4 per cent, 67.5 per cent, 52.6 per cent and 33.8 per cent, and the recurrence-free survival rates were 48.7 per cent, 26.6 per cent, 19.2 per cent and 10.5 per cent respectively. A total of 25 per cent of patients had recurrent disease within 6 months. Margin positivity and progressive disease at liver resection were poor prognostic factors, while adjuvant chemotherapy in margin-positive resections improved overall survival. The bilobar liver metastases from colorectal cancer-overall survival nomogram was developed from the derivation cohort based on pre- and postoperative factors. The nomogram’s ability to forecast overall survival at 1, 2, 3 and 5 years was subsequently validated on the validation cohort and showed high accuracy (overall C-index = 0.742).
Conclusion
Despite the high recurrence rates, overall survival of patients undergoing surgical resection for bilobar liver metastases from colorectal cancer is encouraging. The novel bilobar liver metastases from colorectal cancer-overall survival nomogram helps in counselling and informed decision-making of patients planned for treatment of bilobar liver metastases from colorectal cancer.
At a median follow-up of 50.9 months, the 1-year, 2-year, 3-year and 5-year overall survival rates were 86.4 per cent, 67.5 per cent, 52.6 per cent and 33.8 per cent respectively; the corresponding recurrence-free survival rates were 48.7 per cent, 26.6 per cent, 19.2 per cent and 10.5 per cent; the study demonstrates survival advantage of adjuvant chemotherapy in patients with margin-positive resection.

Journal Article
Adrenal metastases are the most common malignant lesions of the adrenal glands and the second most common tumor after adenomas. The location of the primary tumor is described: lung (39%), breast ...(35%), gastrointestinal tract, among other. Several studies show that surgery improves survival in selected cases.
Retrospective and single-center observational study of patients operated for adrenal metastasis over a period of 11 years. The characteristics of the disease and surgical results were described.
14 suprarenalectomies were performed. The average age was 65.85 years. The primary tumors described: non-small cell lung carcinoma (42.8%) and clear cell renal carcinoma (14.20%). In 92.8% the injury was unilateral. In 64.2% it was metachronous. An initial laparoscopic approach was performed in 85.71%. The morbidity of our series was 14.28%. The median overall survival was 30 months. Survival was 75% per year, 55.5% at 3 years and 40% at 5 years.
Age, primary location, degree of differentiation, histological type, size greater, laterality, disease-free interval, chemotherapy and surgical technique are not associated with changes in survival. In the presence of a single adrenal mass, surgical evaluation is mandatory and surgery could play a role in patients with metastases in other locations with control of the primary disease.
The ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain (CARD)) protein is an scaffold component of different inflammasomes, intracellular multiprotein platforms of ...the innate immune system that are activated in response to pathogens or intracellular damage. The formation of ASC specks, initiated by different inflammasome receptors, promotes the recruitment and activation of procaspase-1, thereby triggering pyroptotic inflammatory cell death and pro-inflammatory cytokine release. Here we describe MM01 as the first-in-class small-molecule inhibitor of ASC that interferes with ASC speck formation. MM01 inhibition of ASC oligomerization prevents activation of procaspase-1 in vitro and inhibits the activation of different ASC-dependent inflammasomes in cell lines and primary cultures. Furthermore, MM01 inhibits inflammation in vivo in a mouse model of inflammasome-induced peritonitis. Overall, we highlight MM01 as a novel broad-spectrum inflammasome inhibitor for the potential treatment of multifactorial diseases involving the dysregulation of multiple inflammasomes.
