Interaction of tumour biology and tumour burden in determining outcome after hepatic resection for colorectal metastases

HPB, Issue 2 2010
Dhanny Gomez
Abstract Aims:, To determine the outcome of colorectal liver metastasis (CRLM) patients based on tumour burden, represented by tumour number and size, and tumour biology as assessed by an inflammatory response to tumour (IRT) and margin positivity. Methods:, Data were collated from CRLM patients undergoing resection from January 1993 to March 2007. Patients were divided into: low (,3 metastases and/or ,3 cm); moderate (4,7 metastases and/or >3,,5 cm); and high (,8 metastases and/or >5 cm) tumour burden. Results:, Seven hundred and five patients underwent resection, of which 154 (21.8%), 262 (37.2%) and 289 (41.0%) patients were in the low, moderate and high tumour burden groups, respectively. The 5-year disease-free (P < 0.001) and overall (P < 0.001) survival were significantly different between the groups. IRT (P < 0.001), extent of resection (P < 0.001) and margin (P < 0.001) also differed between the groups. Sub-group analysis revealed that IRT was the only adverse predictor for disease-free and overall survival in the low group. In the moderate group, IRT predicted poorer disease-free survival on multi-variate analysis. In the high group, R1 resection and transfusion were predictors of poorer disease-free survival and age ,65 years, R1 resection and IRT were adverse predictors of overall survival. Conclusion:, Resection margin influenced the outcome of patients with high tumour burden, hence the importance of achieving clear margins. IRT influenced the outcome of patients with less aggressive disease. [source]

Al-Hussaini A, Taylor RM, Samyn M, Bansal S, Heaton N, Rela M, Mieli-Vergani G, Dhawan A. Long-term outcome and management of hepatopulmonary syndrome in children. Pediatr Transplantation 2010:14:276,282. © 2009 John Wiley & Sons A/S. Abstract:, We aim to report a single center experience of the management and long term outcome of HPS in pediatric liver transplant recipients. A retrospective review of children with HPS from 1990 to 2004. Inclusion criteria: liver disease or portal hypertension, hypoxemia (PaO2 < 70 mmHg or SaO2 < 95%) and intrapulmonary shunting documented by macroaggregated albumin scan ratio of >4% (classified mild group [<20%], moderate group [20,40%] and severe group [>40%]). Resolution of HPS post-liver transplant was defined as PaO2 > 70 mmHg or SaO2 > 95%. Eighteen children (six male [34%], median age at diagnosis of HPS 8.6 [1,15.5] yr) had HPS: biliary atresia (n = 8), idiopathic biliary cirrhosis (n = 4), progressive intrahepatic cholestasis (n = 2), miscellaneous (n = 4). The majority had mild shunting (n = 8). Fourteen underwent transplantation with resolution of HPS in 13. Six developed complications: hepatic artery thrombosis (n = 4), biliary (n = 2). Four children died (28%), two pretransplant. There was a tendency towards shunt fraction worsening to a slower degree over time. One-yr survival rate post-transplant was 93%. Median PaO2 was significantly lower in non-survivors compared to survivors (43 vs. 55.2 mmHg, p = 0.03). There was correlation between oxygen parameters pretransplant and time to HPS resolution post-transplant. HPS is reversible after transplant, but is associated with increasing mortality and morbidity. [source]


Behavioral and psychological symptoms of dementia in untreated Alzheimer's disease patients

PSYCHOGERIATRICS, Issue 1 2007

Abstract Background:, To ascertain the prevalence of psychotic symptoms and behavioral disturbances of dementia patients is useful for families and health care professionals in order to anticipate the progression of Alzheimer's disease (AD) and to recognize deterioration. This study aimed to determine whether behavioral and psychological symptoms of dementia (BPSD) are related to severity of untreated AD. Methods:, Two hundred and two patients were classified into three groups by Functional Assessment Staging score as follows: mild group (n = 92) was at stages 3 or 4; moderate group (n = 80) was at stage 5; and severe group (n = 30) was at stages 6 or 7. We then compared the prevalence of BPSD among the groups. Psychiatric symptoms of BPSD were defined as including hallucinations, delusions, delusional misidentification syndrome and depressive mood; while behavioral disturbances included physical aggression, wandering, adverse sleep and hyperphagia. Results:, In our study, depressive mood, physical aggression and wandering were statistically associated with the severity of AD. Conclusion:, These results are meaningful for caregivers in helping them to understand the anticipated progression of AD and to recognize deterioration. In the care of AD patients, it is necessary to be aware of characteristics of each BPSD. [source]


Establishment of new severity ratings based on analysis of hospital-acquired pneumonia

RESPIROLOGY, Issue 2009
Article first published online: 19 OCT 200
SUMMARY ,,The Japanese Respiratory Society issued its first guidelines for the management of hospital-acquired pneumonia in adults in 2002. Pathological and severity ratings were investigated based on the results of a national multicenter survey of hospital-acquired pneumonia, and the new severity ratings shown below were established (Fig. II-1). Figure II-1. Severity ratings. MRSA, Methicillin-resistant Staphylococcus aureus. ,,Severity ratings in the 2002 guidelines were based mainly on markers that predicted the effectiveness of antimicrobial treatment. In the current revision, severity is rated using markers that predict the prognosis of patients. ,,Five criteria were established as factors that predict prognosis: malignant tumour or immunocompromised status; decreased level of consciousness; FiO2 >35% required to maintain SpO2 >90%; age ,70 years in men or ,75 years in women; and oliguria or dehydration. ,,Two criteria were established as factors specifying the severity of the pneumonia itself: CRP ,200 mg/L and shadows infiltrating more than two-thirds the area of one lung on chest radiography. ,,Patients who satisfy up to two of the five criteria above to predict prognosis are classified in the mild group (Group A) if they do not satisfy either of the two criteria specifying severity of pneumonia, or in the moderate group (Group B) if they satisfy one or both of those two criteria. Patients who satisfy three or fewer of the five criteria to predict prognosis are classified in the severe group (Group C). ,,When the new severity ratings were applied to the results of the national multicenter survey of hospital-acquired pneumonia, the mortality rate was found to be 12.1% (101/834) in the mild group (Group A), 24.9% (69/277) in the moderate group (Group B) and 40.8% (98/240) in the severe group (Group C). Statistically-significant differences were seen between groups, and patient classification may be useful as an indicator of prognosis (Fig. II-2). Figure II-2.
