Endocrine paraneoplastic syndromes are distant manifestations of some tumours. An uncommon but increasingly reported form is tumour-induced osteomalacia, a hypophosphatemic disorder associated to fibroblast growth factor 23 (FGF-23) secretion by tumours. The main biochemical manifestations of this
In a prospective study 60 patients suffering from histologically confirmed renal cell carcinoma were examined on paraneoplastic alterations. The following parameters were determined: Stauffer-syndrome (BSG, total protein with serum electrophoresis, alcaline phosphatase, gamma-GT, Quick values),
OBJECTIVE
We sought to determine the frequency of interleukin-6 (IL-6) expression in renal cancer cell lines, the frequency of the detection of IL-6 in the serum of patients with metastatic renal cell carcinoma, whether serum IL-6 level correlates with the development of paraneoplastic syndromes and
The sera of patients with small cell carcinoma of the lung (SCCL) and an associated visual paraneoplastic syndrome (VPNS) have high titer immunoglobulins that react with retinal ganglion cells and with cloned lines of the SCCL. The immunoglobulins in the sera of two patients with SCCL and VPNS
A case of malignant schwannoma of the sciatic nerve is described associated with hepatic dysfunction in the absence of hepatic metastases. An elevated serum alkaline phosphatase activity was present with an isoenzyme pattern indicating hepatic involvement. These abnormalities disappeared after
OBJECTIVE
We investigated the incidence and prognostic significance of paraneoplastic elevation of serum alkaline phosphatase in patients with renal cell carcinoma.
METHODS
Clinical data of 365 pathologically proved renal cell carcinoma cases were reviewed. Serum alkaline phosphatase level greater
233 SD rats weighing 100 approximately 120 g were divided randomly into 6 groups. The animals in group I and group II received 0.1 mg/kg selenium in the form of sodium selenite only and served as the negative control and positive control, respectively. Animals in groups III, IV and V were fed with
In two patients with renal cell carcinoma, the following biochemical changes were found independently of hepatic metastases: increased alkaline phosphatase activity, rise in bromsulfothalein retention, hypoalbuminemia, increase in alpha2-globulin, and prolonged prothrombin time (Stauffer syndrome).
OBJECTIVE
To evaluate the status and diagnostic utility of antioxidant paraoxonase 1 (PON1) in gastroesophageal cancers.
METHODS
PON1's arylesterase/paraoxonase activities and phenotype were determined in 82 cancers and 57 controls, and related to clinicopathological features, anemia and cachexia
Oncogenic osteomalacia is a rare paraneoplastic syndrome of acquired hypophosphatemic osteomalacia, resulting from a deficit in renal tubular phosphate reabsorption, in which fibroblast growth factor 23 (FGF23) seems to be implicated. This condition is usually associated with a phosphaturic
Stauffer syndrome is a rare paraneoplastic syndrome classically associated with renal cell carcinoma (RCC). This association gave it the historical name of nonmetastatic nephrogenic hepatic dysfunction syndrome without jaundice. It is a syndrome of unclear pathophysiology characterized by a
Because small cell anaplastic carcinoma of the prostate is an uncommon tumor, it has remained a poorly defined entity. To elucidate further the clinical, pathological and immunohistochemical characteristics of this cancer the 27 patients who presented to the Mayo Clinic from 1960 to 1990 were
Phosphaturic mesenchymal tumours are a heterogeneous set of bone and soft tissue neoplasms that can cause a number of paraneoplastic syndromes such as tumour induced osteomalacia. The term phosphaturic comes from the common finding that these tumours secrete high levels of fibroblast growth factor
Paraneoplastic hepatopathy has been reported with various malignancies, most commonly with renal cell cancer. This non-metastatic hepatic dysfunction in such malignancies is known as Stauffer syndrome. We describe a 61-year-old man who presented with symptoms of bowel obstruction with marked
Tumors frequently induce the multifunctional cytokine IL-6, which has been linked to several paraneoplastic syndromes, most notably cachexia. IL-6 stimulates osteoclast formation, causes mild hypercalcemia, and is produced by bone cells in vitro upon exposure to systemic hormones. Since IL-6 is
