Patients can be divided into at least three risk groups depending on the four baseline clinical parameters: performance status, WBC count, alkaline phosphatase and number of metastatic sites. Any molecular or biological marker should be validated against these clinical parameters and decisions for more or less intensive treatments may be studied separately in these three risk groups. Also, clinical trials should be stratified according to the three risk groups.

The data indicate that capillary electrophoresis with mass spectrometry coupling provides a promising tool that permits fast and accurate identification and differentiation of protein patterns in body fluids of healthy and diseased individuals, thus enabling diagnosis based on these patterns.

BACKGROUND In the past 20 years, a dramatic improvement in the prognosis of patients with hepatoblastoma (HB) has been achieved by combining surgery with chemotherapy in several national and international trials. A worldwide, unsolved problem remains the treatment of patients with advanced or metastatic HB. METHODS The German Cooperative Pediatric Liver Tumor Study HB 94 was a prospective, multicenter, single‐arm study. The study ran from January 1994 to December 1998. The protocol assessed the efficiency of chemotherapy consisting of cisplatin, ifosfamide, and doxorubicin (CDDP/IFO/DOXO) and/or etoposide and carboplatin (VP16/CARBO). The prognostic significance of the surgical strategy, pretreatment factors, and tumor characteristics for disease free survival (DFS) were analyzed. RESULTS Sixty‐nine children with HB were treated in the HB 94 study. The median follow‐up of survivors was 58 months (range, 32–93 months). Fifty‐three of 69 patients (77%) remained alive, and 16 of 69 patients (23%) died. Long‐term DFS was as follows: 26 of 27 patients had Stage I HB, 3 of 3 patients had Stage II HB, 19 of 25 patients had Stage III HB, and 5 of 14 patients had Stage IV. A complete resection of the primary tumor was achieved in 54 of 63 patients (86%). Six children (8%) had no surgical treatment. Twenty‐two tumors were resected primarily, and 41 children underwent surgery after initial chemotherapy. Two children underwent liver transplantation. There was no perioperative death. Forty‐eight children received primary chemotherapy with CDDP/IFO/DOXO. Forty‐one of 48 children achieved partial remission after CDDP/IFO/DOXO. Eighteen children with advanced or recurrent HB underwent VP16/CARBO chemotherapy, with a response achieved by 12 children. The relevant pretreatment prognostic factors were growth pattern of the liver tumor (P = 0.0135), vascular tumor invasion (P = 0.0039), occurrence of distant metastases (P = 0.0001), initial α‐fetoprotein level (P = 0.0034), and surgical radicality (P < 0.0001). CONCLUSIONS The current results underline the necessity of preoperative chemotherapy in all children with HB. Complete tumor resection is one of the main prognostic factors.

A persistent bilirubin elevation for longer than 3 months from the time of diagnosis could be identified as a novel marker correlating with a poor outcome. A new prognostic model was developed to predict progression of PSC, which may be useful in timing of liver transplantation.

Our data show that the determination of PCT, IL-6, and C3a is more reliable to differentiate between septic and SIRS patients than the variables CRP and elastase, routinely used at the intensive care unit. The determination of PCT and C3a plasma concentrations appears to be helpful for an early assessment of septic and SIRS patients in intensive care.
