Selective resection of colorectal liver metastases.

AIMS: Safety of liver surgery for colorectal cancer liver metastases after neoadjuvant chemotherapy has to be re-evaluated. PATIENTS AND METHODS: Two hundred Patients were prospectively analyzed after surgery for colorectal cancer liver metastases between 2001 and 2004 at our institution. Special emphasis was given to perioperative morbidity and mortality under modern perioperative care. RESULTS: There was no in-hospital mortality and the perioperative morbidity was 10% (20/200). Four patients had to be reoperated due to bile leak or intraabdominal abscess. The remainder either had infectious complications or pleural effusion and/or ascites requiring tapping. Variables strongly associated with decreased survival were T, N, G and UICC (International Union against cancer) classification of the primary, hepatic lesions>5 cm and elevated tumour markers. Short disease free interval and neoadjuvant chemotherapy without response predicted impaired recurrence free survival (RFS). Multivariate analysis revealed lymph node status and differentiation of the primary, presence of extrahepatic tumour and gender as factors associated with decreased survival. Administration of neoadjuvant chemotherapy was not associated with higher postoperative morbidity or prolonged hospital stay. CONCLUSIONS: Modern dissection techniques and improved perioperative care contributed to a very low rate of surgery-related morbidity (10%) and a zero percent mortality which was also observed in patients pretreated with neoadjuvant chemotherapy prior to resection. Liver resection in experienced hands has become a safe part in the potentially curative attempt of treating patients with metastatic colorectal cancer.

Physical performance and health-related quality of life in men on a liver transplantation waiting list.

Twenty-six men on a liver transplant waiting list (12 had alcoholic cirrhosis, 8 suffered from posthepatitic cirrhosis, and 6 from cirrhosis of other etiologies) were eligible for this observation. Nineteen subjects underwent exercise testing to determine oxygen uptake at anaerobic threshold. In all patients dynamometry was performed to determine isokinetic muscle strength of knee extensor muscles, and handgrip. Quality of life was evaluated in all patients with the MOS SF-36 questionnaire. Child-Pugh A patients showed 54 +/- 8%, Child-Pugh B patients 36 +/- 2%, and Child-Pugh C patients 31 +/- 4% of VO2 max predicted at the anaerobic threshold (Kruskal-Wallis ANOVA, p < 0.05). Isokinetic muscle strength of the quadriceps femoris (left/right) was 149 +/- 20/134 +/- 14 Nm in Child-Pugh A, 108 +/- 16/114 +/- 19 Nm in Child-Pugh B, and 89 +/- 10/81 +/- 11 Nm in Child-Pugh C patients (Kruskal-Wallis ANOVA, p < 0.05). MOS-SF36 revealed a Child-Pugh class dependent reduced functional status (Kruskal-Wallis ANOVA, p < 0.05). No significant differences in target parameters were found when analysed according to the etiology of cirrhosis. Patients on the liver transplant waiting list do have a stage dependent reduction in physical health. These data are the basis for longitudinal studies measuring the effects of preoperative rehabilitation programs in these patients.

Complex mitochondriopathy associated with 4 mtDNA transitions.

In a 33-year-old man, mitochondriopathy was diagnosed upon short stature, auditory impairment, gynaecomastia, hypogonadism, vertical ophthalmoplegia, cerebral atrophy, leucencephalopathy, cataract, hypertrabeculated left ventricle, hypothyroidism, diabetes mellitus, glomerulonephritis necessitating kidney transplantation, general wasting, polyneuropathy, abnormally high lactate levels on exercise, partially reduced cytochrome-c oxidase staining and abnormally structured mitochondria on muscle biopsy. Mitochondrial DNA (mtDNA) analysis revealed 1 novel (A15662G) and 3 known mtDNA transition(s) (T3398C, T4216C, G15812A) affecting the cytb and ND1 gene, respectively. Three of the patient's transitions were also detected in blood leukocytes of the patient's maternal grandmother, mother and brother. Mutant mtDNA was heteroplasmic at >75% in the patient's skeletal muscle.

High proportion of granzyme B-positive (activated) intraepithelial and lamina propria lymphocytes in lymphocytic gastritis.

Intraepithelial lymphocytes (IELs) and lamina propria lymphocytes (LpLs) have not been well studied in gastric mucosa, particularly in lymphocytic gastritis. Therefore, they were immunohistologically characterized with antibodies recognizing CD3, CD8, CD57, T cell-restricted intracellular antigen (TIA-1), and granzyme B (GrB). The TIA-1 labels cytotoxic granules of resting and activated T-cells, whereas GrB decorates activated cytotoxic T cells. Thirty patients with celiac disease, including 20 taking gluten and 10 on a gluten-free diet, 15 patients with nonceliac disease-associated lymphocytic gastritis, and 20 controls were studied. Stained cells were counted and results were given as IELs/100 epithelial cells or percentage of lamina propria cells. Sixty percent to 90% of CD3+ IELs and up to 12% of lamina propria cells contained TIA-1-positive cytotoxic granules. The number of GrB+ IELs and LpLs was increased in Helicobacter pylori-positive controls (p < 0.03 vs. H pylori-negative controls) and celiac disease patients taking gluten (p < 0.05 vs. controls). The highest number of GrB+ IELs and LpLs was found in nonceliac disease-associated lymphocytic gastritis (p < 0.009 vs. controls, p < 0.05 vs. celiac disease). This study shows that a high proportion of gastric IELs and LpLs is potentially cytotoxic in nature. Through stimuli not yet identified, a proportion of them becomes activated after H pylori infestation and in lymphocytic gastritis.

The advantage of allocating kidneys from old cadaveric donors to old recipients: a single-center experience.

BACKGROUND: In January 1999 a new kidney allocation program was launched by the Eurotransplant Foundation, the 'Eurotransplant Senior Program' (ESP). Cadaveric donors above the age of 65 yr are allocated to kidney transplant recipients of the same age group. METHODS: Using a single-center database, 91 patients who underwent first renal transplantation at the age of 65 yr and older in the years 1999-2002 were identified. Fifty-six patients were transplanted through ESP allocation (study group) and 35 patients (control group) via normal Eurotransplant Kidney Allocation System (ETKAS) procedure. RESULTS: Age, sex and comorbid conditions did not differ by group. The rate of acute rejection episodes, primary non-function, delayed graft function, perioperative mortality did not differ by group. Serum creatinine was significantly lower in the ETKAS group (1.3 vs. 1.9 mg/dL; p=0.015) from six months after the transplantation on. Overall graft survival at six yr was 56% in the ETKAS group and 52% in the ESP group. With 73% in the ETKAS group and 71% in the ESP group, cumulative patient survival according to the Kaplan-Meier estimation was not statistically different at five yr. CONCLUSIONS: We did not find a relevant difference in the outcome between young and old kidney transplants in old recipients after this long observation period.
