Liver transplantation for patients with metastatic endocrine tumors: single-center experience with 15 patients

In contrast to other secondary liver malignancy, orthotopic liver transplantation (OLT) is considered as a treatment modality for nonresectable endocrine liver metastases in selected patients. However, only few series have assessed patient selection criteria and long-term results, and no reports have focused on the impact of new technologies in this regard. Between 1992 and 2004, 28 patients with malignant endocrine tumors underwent evaluation for OLT according to our protocol. Data were entered into a prospective database. During pretransplant evaluation, somatostatin receptor scintigraphy detected extrahepatic metastases not diagnosed in standard imaging in 10 patients. Of them, 3 showed aberrant Ki67 labeling results. One patient was excluded from further evaluation due to severe carcinoid heart. Thus far, 15 patients, 10 men and 5 women, aged 37 to 67 years, were subjected to the transplant procedure (11 deceased donor OLT, 3 living donor liver transplantations, and 1 cluster transplantation). Four patients died during the hospital treatment. The median follow-up of the discharged patients was 60.8 months. The actuarial patient survival was 78.3% at 1 year and 67.2% at 5 years. The actuarial 1-, 2-, and 5-year tumor-free survival amounted to 69.4%, 48.3%, and 48.3%, respectively. Two patients underwent surgery for isolated tumor recurrence. In 2 patients, peptide receptor radiotherapy was carried out because of multilocular recurrent disease. In conclusion, liver transplantation is a realistic therapeutic option for highly selected patients with hepatic metastases of endocrine tumors. Our strategy, which implements strict pretransplant selection and aggressive surgical approach, in case of disease recurrence, in addition to systemic radiopeptide treatment, led to an excellent long-term survival cure, however, is unlikely to be achieved.

Tripartite patella: late appearance of a third ossification center in childhood

Bilateral radiographic progression of the supero-lateral fragment of a bipartite- into a tripartite patella with unilateral symptoms. An 8 year old girl presented a bilateral bipartite patella Stage III as an incidental finding after fall on the flexed right knee. Serial radiographs two years later revealed a bilateral progression of the bipartite- into a tripartite patella with complaints only on the post-traumatic right side. Observation was opted as therapy. There was no correlation of symptoms and radiological findings of the fragmentation of the bipartite- into a tripartite patella. Therefore we conclude the etiology of a bilateral late appearance of a third ossification center.

[On quality of life after surgical therapy of oral cancer - a retrospective multi-center study: the connection between dedentition, denture, quality of life, and dysphagia, and the resulting rehabilitation schemes]

PURPOSE: The surgical treatment of oral cancer results in functional and aesthetical impairments. Patients' quality of life is considerably impaired by oral symptoms resulting from therapy of oral cancer. In many cases the inevitable resection of the tumor, as well as the adjuvant radiochemotherapy will cause the destruction of physiologically and anatomically important structures. One focus of research was the specific rehabilitation of dental loss by functional dentures. Another was the course of 19 impairments (comprehension of speech for unknown others, comprehension of speech for familiar others, eating/swallowing, mobility of the tongue, opening range of the mouth, mobility of lower jaw, mobility of neck, mobility of arms and shoulders, sense of taste, sense of smell, appearance, strength, appetite, respiration, pain, swelling, xerostomia, halitosis). METHODS: Commissioned by the German, Austrian and Swiss cooperative group on tumors of the maxillofacial region (DOSAK), data were collected in 3.894 questionnaires at 43 hospitals in Germany, Austria and Switzerland. The catalogue comprised 147 items in 9 chapters. At the end of the enquiry, 1.761 anonymous questionnaires were returned by 38 hospitals. 1.652 of these could be evaluated regarding the question. RESULTS: The sum score of the 19 impairments was highly increased immediately after the operation and recovered over the next 6 months, without, however, reaching the pre-surgery level. Of 1.652 patients, only 35% did not lose any teeth during therapy. 23% lost up to 5, 17% up to 10 teeth. A quarter of the patients lost more than 10 teeth. The more teeth were lost, the greater the decline of quality of life (p < or = 0.001), although this could be allayed by the functionality of the dentures (p < or = 0.001). There is a reciprocal dependence between the functionality of dental prosthetics and impairment by eating/swallowing (p < or = 0.001). CONCLUSIONS: Patients' quality of life after radical surgery of a carcinoma of the oral cavity depends not only on the functionality of dentures and the specificity of rehabilitation, but also from the initial findings, the extent and location of the resection, the chosen therapy, the general circumstances of the patient's life as well as their strategies of coping. These factors, however, unlike those of functionality of dental prosthesis and rehabilitation, are not modifiable.

An implantable carotid sinus baroreflex activating system: surgical technique and short-term outcome from a multi-center feasibility trial for the treatment of resistant hypertension

OBJECTIVES: To assess perioperative outcomes and blood pressure (BP) responses to an implantable carotid sinus baroreflex activating system being investigated for the treatment of resistant hypertension. METHODS: We report on the first seventeen patients enrolled in a multicenter study. Bilateral perivascular carotid sinus electrodes (CSL) and a pulse generator (IPG) are permanently implanted. Optimal placement of the CSL is determined by intraoperative BP responses to test activations. Acute BP responses were tested postoperatively and during the first four months of follow-up. RESULTS: Prior to implant, BP was 189.6+/-27.5/110.7+/-15.3 mmHg despite stable therapy (5.2+/-1.8 antihypertensive drugs). The mean procedure time was 202+/-43 minutes. No perioperative strokes or deaths occurred. System tests performed 1 or up to 3 days postoperatively resulted in significant (all p < or = 0.0001) mean maximum reduction, with standard deviations and 95% confidence limits for systolic BP, diastolic BP and heart rate of 28+/-22 (17, 39) mmHg, 16+/-11 (10, 22) mmHg and 8+/-4 (6, 11) BPM, respectively. Repeated testing during 3 months of therapeutic electrical activation demonstrated a durable response. CONCLUSIONS: These preliminary data suggest an acceptable safety of the procedure with a low rate of adverse events and support further clinical development of baroreflex activation as a new concept to treat resistant hypertension.
