ABSTRACT
OBJECTIVES: The aim of the study is to evaluate the predictive value of the model for end-stage liver disease (MELD) score for mortality in stable angina pectoris patients undergoing coronary artery bypass graft (CABG) surgery. METHODS: We retrospectively analyzed 261 consecutive patients with stable angina pectoris who underwent CABG while not being on anticoagulant therapy. The patients were divided into two groups: survivors and non-survivors. The MELD score was calculated for all patients. The all-cause mortality within postoperative 12 months was the primary end point of the study. RESULTS: The follow-up period was 12 months. The non-survivors were older (72.0±6.1 vs 62.4±8.4, p<0.001). The MELD score was significantly higher in the non-survivors group (7.5±1.2 vs 6.7±0.7, p<0.001). The MELD score (p=0.001) was an independent predictor of postoperative one-year mortality. The addition of MELD score to EuroSCORE II significantly improved the prognostic performance of the EuroSCORE II (EuroSCORE II vs EuroSCORE II plus MELD score: AUCs: 0.792 vs 0.842). CONCLUSION: Our research showed that the MELD score could be useful to predict mortality in patients who have stable coronary artery disease, and are undergoing CABG surgery (Tab. 3, Fig. 2, Ref. 25).

AIM: A retrospective study to evaluate the prognostic influence of the primary tumour and the anatomic level of spinal metastases was carried out. MATERIAL AND METHODS: Between January 1984 and May 2005, 217 patients were surgically treated because of spinal metastases. The prognostic influence for the survival was analysed for the entity of the primary tumour and the localisation of the spinal metastases. RESULTS: The median survival of the study group was 8.0 months (range: 0-191.5 months). Mamma carcinoma was the most frequent primary tumour with 62 cases (28.6 %). The spinal level of the metastases did not influence the postoperative survival (p = 0.9058). The entity of the primary tumour showed a significant influence for the postoperative survival (p < 0.0001). CONCLUSION: In spinal metastases, the entity of the primary tumour was of prognostic value; the localisation of the spinal metastases at different spinal levels did not influence the postoperative survival. Therefore, the evaluation of the primary tumour is mandatory for an estimation of the expected survival.

AIM: The Tokuhashi prognosis score consists of six parameters. The sum of points rated for each parameter can be correlated with the prognosis. This study evaluates the score variations that have been done by different authors and Tokuhashi et al. themselves. METHODS: Two hundred and seventeen consecutive patients, surgically treated for vertebral metastases, were studied retrospectively. We calculated the original and modified score of Tokuhashi and evaluated the predictive value for the individual life expectancy. RESULTS: The original and modified Tokuhashi score assured a significant predictive value. Modified criteria by the authors showed the highest reliability between the predicted and real survival, and the patients could be allocated correctly to the desirable instrumentation. CONCLUSION: The original and modified Tokuhashi score showed a significant predictive value. The modified criteria by the authors showed the highest reliability between predicted and real survival.

AIM: The aim of this study was the evaluation of surgical results and prognostic factors in spinal metastases of renal cancer. METHODS: 37 surgical patients with spinal metastases of renal cell carcinoma were retrospectively analysed. In 2 patients the cervical, in 16 patients the thoracic, in 4 patients the thoraco-lumbar and in 16 patients the lumbar spine was involved. RESULTS: In 11 cases (29.7 %) a combined posterior-anterior spondylodesis with vertebral body replacement, in 26 cases (70.3 %) a single posterior instrumentation was done. Perioperatively, 24 complications appeared, 4 of them were lethal. Postoperatively, the neurological situation was unchanged in 26 patients, dischanged in 4 patients and improved in 7 patients. The level of pain was unchanged in 10 patients, dischanged in 3 patients and improved in 24 patients. The mean postoperative survival was 13.6 months. For the postoperative survival the Karnofsky-Index and the Frankel-Score were univariate highly significant, the factors nutritional condition and latency between the primary tumor and the development of spinal metastases showed a lower significancy. No prognostical influence for the postoperative survival could be detected for the factors gender, age, localisation of the metastases, type of operation and the factor solitary/multiple metastases. The multivariate analyses did not attempt any of the univariate significant prognostic factors for the postoperative survival. The postoperative survival was significantly (p: 0.0030) influenced by postoperative adjuvant therapy (radio- and/or chemotherapy). The analysis of each adjuvant therapy form (i. e. chemo-, radio- and combined therapy) attempts this prognostic effect (p: 0.0229). CONCLUSION: In most patients with spinal metastases of renal cell carcinoma, the singular posterior intrumentation combined with a decompression is a sufficient therapy. To avoid posterior implant failure, in patients with a prognosticated survival of more than one year, a combined posterior-anterior spondylodesis with vertebral body replacement should be done. The prognostic influence of an adjuvant postoperative treatment in the present study must be interpreted in the context of this small, highly selected patient collective. Further standardized studies should be performed to evaluate the prognostic influence of an adjuvant therapy.
