Interventionally implanted port catheter systems for hepatic arterial infusion of chemotherapy in patients with colorectal liver metastases: A phase II-study and historical comparison with the surgical approach

<p>Abstract</p> <p>Background</p> <p>The high complication rates of surgically implanted port catheter systems (SIPCS) represents a major drawback in the treatment of isolated liver neoplasms by hepatic arterial infusion (HAI) of chemotherapy. Interventionally implanted port catheter systems (IIPCS) have evolved into a promising alternative that enable initiation of HAI without laparatomy, but prospective data on this approach are still sparse. Aim of this study was to evaluate the most important technical endpoints associated with the use of IIPCS for the delivery of 5-fluorouracil-based HAI in patients with colorectal liver metastases in a phase 2-study, and to perform a non-randomised comparison with a historical group of patients in which HAI was administered via SIPCS.</p> <p>Methods</p> <p>41 patients with isolated liver metastases of colorectal cancer were enrolled into a phase II-study and provided with IIPCS between 2001 and 2004 (group A). The primary objective of the trial was defined as evaluation of device-related complications and port duration. Results were compared with those observed in a pre-defined historical collective of 40 patients treated with HAI via SIPCS at our institution between 1996 and 2000 (group B).</p> <p>Results</p> <p>Baseline characteristics were balanced between both groups, except for higher proportions of previous palliative pre-treatment and elevated serum alkaline phosphatase in patients of group A. Implantation of port catheters was successful in all patients of group A, whereas two primary failures were observed in group B. The frequency of device-related complications was similar between both groups, but the secondary failure rate was significantly higher with the use of surgical approach (17% vs. 50%, p < 0.01). Mean port duration was significantly longer in the interventional group (19 vs. 14 months, p = 0.01), with 77 vs. 50% of devices functioning at 12 months (p < 0.01). No unexpected complications were observed in both groups.</p> <p>Conclusion</p> <p>HAI via interventionally implanted port catheters can be safely provided to a collective of patients with colorectal liver metastases, including a relevant proportion of preatreated individuals. It appears to offer technical advantages over the surgical approach.</p

Spina bifida at the sacral level: more than minor gait disturbances

Objective: To investigate functional outcome in two groups of children with sacral level paralysis: myelomeningocele (MMC) versus lipomyelomeningocele (LMMC). Additionally both groups were compared with each other and when possible with reference values. Design: Cross-sectional study by means of ( 1) clinical assessment, and ( 2) disability measurement. Setting: Spina bifida outpatient clinic at a university hospital in the Netherlands. Subjects: Sample of 30 children with MMC and 14 with LMMC. Mean age (SD) 6.0 (4.9) and 8.4 ( 4.9) years respectively. Main measures: Muscle strength, ambulation level, motor performance (Bayley Scales of Infant Development (BSID) and Movement Assessment Battery for Children), and the Pediatric Evaluation of Disability Inventory (PEDI). Results: The majority of patients in both groups were normal ambulant, 14/21 (67%) in MMC and 9/14 (64%) in LMMC. Ambulation was strongly associated with muscle strength of hip abductors (odds ratio (OR): 13.5, 95% confidence interval (CI) 2.5 - 73.7), and ankle dorsal-flexor muscles ( OR: 110, 95% CI 8.9 - 135.9). No significant differences were found in lesion and ambulation level. Muscle strength and motor performance were significantly lower in the MMC group than in the LMMC group ( p <0.05). PEDI scores were comparable in both groups. Most problems were noted in mobility skills and caregiver assistance in self-care, especially regarding bladder and bowel management. Conclusions: Gross motor and functional problems were seen in both groups. The MMC group showed more muscle weakness and motor problems. However, in both groups caregiver assistance was needed for a prolonged period, especially regarding bladder and bowel management. These findings need special attention, particularly in children who attend regular schools
