Introduction This work presents a comparative biological evaluation of 90Y- and 177Lu- labelled DOTA-SCN and DOTA-NHS conjugated to Rituximab in tumour-bearing mice. Materials and methods Two DOTA derivatives, p-SCN-Bn-DOTA and DOTA-NHS-ester were conjugated to Rituximab and then freeze-dried kit formulations were prepared, as previously described [1]. Tissue distribution was investigated in t...

Cardiac rhabdomyoma is the most common tumour of the heart in infancy and childhood, representing approximately 60% of all primary cardiac tumours in these age groups. Though they have a tendency to regress with advancing age and are histologically benign, rhabdomyomas may cause mechanical obstruction to blood flow, arrhythmia, congestive cardiac failure and death and may be associated with und...

Cardiac failure attributable to malignant disease is generally accepted as being caused either by lymphangitis carcinomatosa or by impaction of tumour emboli in the pulmonary vascular bed. Standard textbooks (Wood, 1956; Anderson, 1961) make no mention of other cardiac lesions which may occur in malignancy and which may be responsible for the development of heart failure. There are some less we...

Giant cell tumour (GCT) is a benign, locally aggressive tumour of the bone that accounts for 5% of primary bone tumours and 21% of benign bone tumours. This tumour more commonly presents as a single (solitary) lesion; however, it may appear with multiple (multicentric) lesions in less than 1% of the cases. According to the literature, 1-9% of solitary GCTs metastasizes to the lung, more commonl...

OBJECTIVES Increased activity of pro-inflammatory cytokines in the circulation has been observed in many, though not all, patients with congestive heart failure. To identify the predictors of cytokine activation in congestive heart failure, we assessed the relationship of peripheral and hepatic venous cytokines to central haemodynamics, neuroendocrine status and intermediary metabolism in patie...

BACKGROUND When hormones are detected in the serum of patients with bronchial carcinoma they are generally considered to originate from the tumour, but this may be not the only explanation. Pulmonary endocrine cells proliferate in lungs affected by non-neoplastic disease and their products are often demonstrable in the serum. The aim of this study was to examine the pulmonary endocrine systems ...

AIMS Inflammatory and immune activation and body wasting are important features of end-stage chronic heart failure. It is not known whether restoration of cardiac output by assist device implantation can improve these abnormalities. METHODS We studied 48 patients (39 males; age 45+/-2 years) with NYHA class IV heart failure. All patients underwent ventricular assist device implantation for en...

Malignant melanoma has an aggressive biological behaviour and a high rate of cardiac involvement. As shown from post-mortem studies, metastases of melanoma can involve any organ and cardiac metastases are frequent. This report describes a case of widespread malignant melanoma in a patient with clinical presentation of complete atrioventricular (AV) block. Thorax CT and transthoracic echocardiog...
