ABSTRACT

A 54-year-old female patient presented with a progressive and deteriorating dyspnea at the slightest exertion in particular during the past few days before presentation. Transthoracic echocardiography revealed a large space-occupying lesion in the right atrium extending into the inferior vena cava (IVC). Abdominal magnetic resonance aortography showed an elongated space-occupying lesion in the IVC with a significant portion of the tumor and almost completely filling the right atrium accompanied by an infiltration of the hepatic and renal veins. A pronounced tumor infiltration of the IVC at the level of the liver was confirmed intraoperatively and immunohistochemical analysis showed a moderate to poorly differentiated leiomyosarcoma. The extended tumor was successfully removed by a complex operation of the thorax and abdomen but the procedure was accompanied by severe bleeding. A few hours following the procedure the patient died due to a further episode of irreversible intra-abdominal hemorrhage.

ABSTRACT

BACKGROUND: Pegylated liposomal doxorubicin has an enhanced efficacy and reduced toxicity compared with free doxorubicin. The efficacy and toxicity of pegylated liposomal doxorubicin was investigated in patients with hepatocellular carcinoma. PATIENTS AND METHODS: Patients with histologically confirmed, locally advanced or metastatic hepatocellular carcinoma and a Karnofsky index > 60% were included in this prospective single-arm study. Exclusion criteria were liver cirrhosis stage Child-Pugh C, previous chemotherapy, or chemoembolization. Pegylated liposomal doxorubicin was given in a dose of 30 mg/m2 every three weeks until progression of disease. After inclusion of five patients the dose could be escalated to 40 mg/m2 in absence of toxicity grade 3 and 4. RESULTS: Sixteen patients were evaluable for response. No objective response was achieved. The median survival time was 140 days (95% confidence interval: 126-154 days). Treatment toxicities grade > or = 3 comprised increased liver enzymes in patients with preexisting grade 1 or 2 elevation (n = 6), hematologic toxicity (n = 5), and hypersensitivity (n = 2). CONCLUSIONS: Pegylated liposomal doxorubicin is not effective for treatment of advanced hepatocellular carcinoma. The favorable toxicity profile was confirmed even in patients with underlying liver disease.

ABSTRACT

BACKGROUND: The definite diagnosis of pancreatic tumors of unknown origin remains a clinical challenge. Imaging techniques may fail to differentiate malignant tumors from inflammation, especially in chronic pancreatitis. In a considerable number of cases, the definitive diagnosis needs laparotomy. Single tumor markers as CA 19-9 or CEA are of limited value in these cases because of their limited sensitivity and specificity. This study was performed to find out, whether a classification method based on fuzzy logic analysis of tumor marker profiles is feasible in patients with pancreatic carcinoma and benign pancreatic disease. PATIENTS AND METHODS: Tumor markers and other clinical and laboratory parameters of 74 consecutive patients, either with histologically proved pancreatic carcinoma (n = 43) or presumed benign pancreatic disease (n = 31) assessed by ultrasound, endoscopic retrograde pancreatography, or computed tomography were analysed in order to detect their diagnostic value in the multi-dimensional approach of fuzzy logic analysis. RESULTS: Given a specificity of 95%, sensitivity was considerably increased by the fuzzy logic method (83%) compared with the best single tumor marker CA 19-9 (65%). CA 19-9, CYFRA 21-1 and CA 15-3 gave the most considerable contributions to the classification system, whereas CEA, CA 125, CA 72-4, AFP, liver enzymes, lipase, amylase, bilirubin, and ferritin were of no or little value. CONCLUSIONS: Tumor marker profiles analysed with the fuzzy logic method may have an improved sensitivity compared with single standard tumor markers. The diagnostic efficacy should be proved in patients with pancreatic tumors of unknown origin.
