AIM This study was performed to evaluate the concordance in pathological assessments of blood and lymphatic vessel invasion (BLI) in pT1 colorectal cancers and to assess the effect of diagnostic criterion on consistency in the assessment of BLI. METHODS Forty consecutive patients undergoing surgical resection of pT1 colorectal cancers were entered into this study. H&E-stained, D2-40-stained and elastica-stained slides from the tumours were examined by 18 pathologists from seven countries. The 40 cases were divided into two cohorts with 20 cases each. In cohort 1, pathologists diagnosed BLI using criteria familiar to them; all Japanese pathologists used a criterion of BLI from the Japanese Society for Cancer of the Colon and Rectum (JSCCR). In cohort 2, all pathologists used the JSCCR diagnostic criterion. RESULTS In cohort 1, diagnostic concordance was moderate in the US/Canadian and European pathologists. There were no differences in the consistency compared with results for Japanese pathologists, and no improvement in the diagnostic concordance was found for using the JSCCR criterion. However, in cohort 2, the JSCCR criterion decreased the consistency of BLI diagnosis in the US/Canadian and European pathologists. The level of decreased consistency in the assessment of BLI was different between the US/Canadian and European pathologists. CONCLUSIONS A uniform criterion strongly influences the diagnostic consistency of BLI but may not always improve the concordance. Further study is required to achieve an objective diagnosis of BLI in colorectal cancer. The varying effects of diagnostic criterion on the pathologists from Japan, the USA/Canada and Europe might reflect varied interpretations of the criterion. Internationally accepted criterion should be developed by participants from around the world.

The objectives of this study were to describe a new spinal cord injury scale for dogs, evaluate repeatability through determining inter-rater variability of scores, compare these scores to another established system (a modified Frankel scale), and determine if the modified Frankel scale and the newly developed scale were useful as prognostic indicators for return to ambulation. A group of client-owned dogs with spinal cord injury were examined by 2 independent observers who applied the new Texas Spinal Cord Injury Score (TSCIS) and a modified Frankel scale that has been used previously. The newly developed scale was designed to describe gait, postural reactions and nociception in each limb. Weighted kappa statistics were utilized to determine inter-rater variability for the modified Frankel scale and individual components of the TSCIS. Comparisons were made between raters for the overall TSCIS score and between scales using Spearman's rho. An additional group of dogs with surgically treated thoracolumbar disk herniation was enrolled to look at correlation of both scores with spinal cord signal characteristics on magnetic resonance imaging (MRI) and ambulatory outcome at discharge. The actual agreement between raters for the modified Frankel scale was 88%, with a weighted kappa value of 0.93. The TSCIS had weighted kappa scores for gait, proprioceptive positioning and nociception components that ranged from 0.72 to 0.94. Correlation between raters for the overall TSCIS score was Spearman's rho=0.99 (P<0.001). Comparison of the overall TSCIS score to the modified Frankel score resulted in a Spearman's rho value of 0.90 (P<0.001). The modified Frankel score was weakly correlated with the length of hyperintensity of the spinal cord: L2 vertebral body length ratio on mid-sagittal T2-weighted MRI (Spearman's rho=-0.45, P=0.042) as was the overall TSCIS score (Spearman's rho=-0.47, P=0.037). There was also a significant difference in admitting modified Frankel scores (P=0.029) and admitting overall TSCIS scores (P=0.02) between dogs that were ambulatory at discharge and those that were not. Results from this study suggest that the TSCIS is an easy to administer scale for evaluating canine spinal cord injury based on the standard neurological exam and correlates well with a previously described modified Frankel scale.

OBJECTIVE To evaluate changes over time in owner-perceived, weighted quality-of-life assessments in dogs with spinal cord injuries and determine whether scores were associated with underlying etiology or with veterinarian-assigned scores for severity of neurologic dysfunction. DESIGN Cohort study. ANIMALS 100 dogs with spinal cord injury. PROCEDURES Duration of dysfunction, modified Frankel neurologic injury score, and etiology were recorded. At initial and recheck (4- to 6-week) evaluations, owners were asked to identify 5 areas or activities they believed had the most influence on their dogs' quality of life, assess their dogs' current status in each area, and provide a weighting for the importance of each area; results were used to construct a weighted quality-of-life score. Owners were also asked to provide a quality-of-life score with a visual analog scale (VAS). RESULTS At initial and recheck evaluations, weighted quality-of-life scores were higher for ambulatory than for nonambulatory dogs. However, scores did not differ among groups when dogs were grouped on the basis of underlying etiology or duration of injury. Dogs with an increase in Frankel score between the initial and recheck evaluations had a significant increase in weighted quality-of-life score, whereas for dogs that did not have any change in Frankel score, initial and recheck weighted quality-of-life scores were not significantly different. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that owner-assigned, weighted quality-of-life scores for dogs with spinal cord injuries did not vary significantly on the basis of underlying etiology or duration of injury but were higher for ambulatory than for nonambulatory dogs.
