ABSTRACT

AIM: As the understanding of anal dysplasia continues to develop, controversy remains regarding treatment of these lesions. The purpose of this study was to evaluate lesion type (flat vs exophytic) and the association between morphology and dysplasia. METHODS: This was a single-centre retrospective analysis of a prospectively collected pathological database of patients > 17 years old who underwent operative excision/biopsies for presumed anal condyloma or dysplasia from 2009 to 2018. The analysis includes comparisons between patient factors, phenotype and grade of dysplasia. RESULTS: Sixty-nine patients had 423 lesions. The mean age of the study population was 48.2 years. 62.3% were men and 46.4% of patients were black. 47.8% of patients were human immunodeficiency virus (HIV) positive and 39.1% were men who have sex with men (MSM). There were 176 (41.6%) flat lesions and 234 (55.3%) exophytic lesions. Exophytic lesions were 2.5-fold more likely to be associated with a higher grade of dysplasia than flat lesions (OR 2.63, 95% CI 1.09-6.32). Neither lesion type nor dysplasia severity was associated with human papillomavirus, lesion location or patient characteristics, including race, MSM or HIV status. DISCUSSION: Exophytic lesions were more than twice as likely to have advanced dysplasia compared with flat lesions. A clearer understanding of the association between gross lesion appearance and dysplasia will allow more appropriate counselling of patients and the development of better screening and treatment guidelines for anal condylomata and dysplasia.

ABSTRACT

AIM: Sarcopenia, or a reduction of lean muscle mass, is associated with poorer outcomes in cancer patients. Few previous studies have examined this potentially correctable risk factor in patients with locally advanced rectal cancer. METHOD: Skeletal muscle mass index was measured retrospectively on initial staging CT scans of patients undergoing chemoradiation followed by radical resection for rectal cancer for the period 2007-2013. Patients were categorized as sarcopenic or nonsarcopenic and differences in terms of demographics, pre-, peri- and postoperative outcomes were examined. RESULTS: Forty-seven patients were included; their mean age was 59.3 (36-82) years and 61.7% were men. We considered that 55.2% of men and 44.4% of women were sarcopenic; the overall prevalence of sarcopenia was 51.1%. Age, preoperative haemoglobin and albumin were significantly related to sarcopenia. Body mass index (BMI) and obesity (BMI > 30 kg/m2 ) were not associated with sarcopenia. Blood transfusions were more frequent in sarcopenic patients (P = 0.001). Although readmissions and length of stay were not increased, overall postoperative complications were significantly higher in sarcopenic patients (P = 0.03). Neither BMI nor obesity was associated with postoperative complications. CONCLUSION: Sarcopenia was present in over 50% of patients with locally advanced rectal cancer at diagnosis. It was associated with a higher incidence of both blood transfusion and postoperative complications. BMI did not correlate with these negative outcomes. Sarcopenia may be a better predictor of surgical outcomes than BMI or obesity.

ABSTRACT

The effects of etodolac, a new nonsteroidal anti-inflammatory drug, on gastrointestinal (GI) microbleeding were quantitatively assessed in two studies in healthy adult men. The first was a two-group, open-label, parallel comparison of etodolac, 600 mg/day, aspirin, 2600 mg/day, and placebo in 20 subjects; the second was a four-group, double-blind, parallel comparison of etodolac, 600, 800, and 1200 mg/day, aspirin, 2600 mg/day, and placebo in 41 subjects. Subjects in both studies received a single-blind placebo on days 1 through 7, either etodolac or aspirin on days 8 through 14, and a single-blind placebo on days 15 through 19. GI blood loss (milliliters per day) was estimated by the radiolabeled (51Cr) erythrocyte method and was based on daily radioactivity counts of stool specimens and regression-estimated daily blood radioactivity. Etodolac, 600 mg/day, induced no significant GI blood loss at any time during the experiments, nor was there significant blood loss after 800 and 1200 mg/day in experiment 2. Blood loss was noted after aspirin in both.
