BACKGROUND Sexually transmitted infection with the human papillomavirus (hpv) is responsible for a significant burden of human cancers involving the cervix, anogenital tract, and oropharynx. Studies in the United States and Europe have demonstrated an alarming increase in the frequency of hpv-positive oropharyngeal cancer, but the same direct evidence does(More)
Sperm chromosome abnormalities were assessed in testicular cancer patients before and after treatment with BEP (bleomycin, etoposide, cisplatin). The frequencies of disomy for chromosomes 1, 12, X, Y and XY were assessed along with diploid frequencies and sex ratios by multicolour fluorescence in situ hybridization (FISH). For each cancer patient, a minimum(More)
AIM Several new biomarkers, such as lipopolysaccharide binding protein (LBP) and interleukin-6 (IL-6), have the potential to determine the severity and outcome of infectious diseases. LBP and IL-6 serum levels have not been reported in patients with gastrointestinal infections. The aim of this study was to compare established markers of infection with new(More)
The current study was designed to describe the long-term life quality and sexuality of men enrolled in a phase 2 clinical trial of cryosurgery for the treatment of localized prostate cancer. A total of 75 men were administered the Functional Assessment of Cancer Treatment-Prostate (FACT-P) before treatment and after treatment at 6 weeks, and at 3, 6, 12,(More)
BACKGROUND A recent randomized trial to compare external beam radiation therapy (EBRT) to cryoablation for localized disease showed cryoablation to be noninferior to external beam EBRT in disease progression and overall and disease-specific survival. We report on the quality of life (QOL) outcomes for this trial. METHODS From December 1997 through(More)
BACKGROUND Peginterferon-alpha 2a (40 kDa), PEGASYS(TM) (PEG-IFN), is a modified form of recombinant human interferon (IFN)-alpha 2a with sustained absorption and prolonged half-life after subcutaneous administration. A phase II trial was conducted in previously untreated patients with advanced renal cell carcinoma (RCC) to assess efficacy, toxicity and(More)
BACKGROUND Early detection of circulating tumor cells (CTCs) offers the possibility of improved outcome for patients with head and neck squamous cell cancer (HNSCC). METHODS Patients with advanced-stage HNSCC (stage III/IV) were tested for CTCs using the CellSearch system (a registered trade name), which has been approved by the U.S. Food and Drug(More)
The purpose of this phase I trial was to establish the maximum tolerated dose and define the dose-limiting toxicities of a combination of temsirolimus and metformin. Patients with advanced solid tumours who had exhausted standard treatment options were eligible. Treatment included weekly intravenous temsirolimus and daily oral metformin. Eleven patients(More)
BACKGROUND Localized prostate cancer can be treated several different ways, but head-to-head comparisons of treatments are infrequent. The authors of this report conducted a randomized, unblinded, noninferiority trial to compare cryoablation with external beam radiotherapy in these patients. METHODS From December 1997 through February 2003, 244 men with(More)
Small cell carcinomas (SCC) most commonly arise from the lung.1 These tumours are aggressive, present with early metastasis and are associated with a poorer prognosis compared to non-small cell lung cancer.2,3 Extra-pulmonary SCC was first described by Duguid and Kennedy in 19304 and subsequently has been reported in the gastrointestinal tract,5 head and(More)
