RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This clinical trial is studying blood samples in predicting how patients with prostate cancer will respond to treatment with docetaxel.
- To determine if mRNA present in circulating tumor cells will help predict response in patients with hormone-refractory prostate cancer treated with docetaxel.
- To develop a predictive model based on the most accurate and sensitive combination of these biomarkers.
OUTLINE: This is a multicenter study.
Blood samples are collected for biomarker laboratory studies at baseline, every 3-4 weeks during study, and at disease progression or every 12 weeks after completion of study. Samples are analyzed for mRNA via RT-PCR.
All patients receive docetaxel on a weekly, biweekly, or three-weekly schedule at the discretion of the treating physician.
Primary Purpose: Treatment
docetaxel, RNA analysis, reverse transcriptase-polymerase chain reaction, laboratory biomarker analysis

The primary purpose of this study is to validate the sensitivity and specificity of the Respirio Flu Test and the eLab Flu Test in detecting Influenza A as compared to the gold standard fo...
Human telomerase reverse transcriptase (TERT) is the catalytic subunit of telomerase, and it elongates telomere through RNA-dependent DNA polymerase activity. Although TERT is named as a reverse trans...
We assessed the applicability of giant unilamellar vesicles (GUVs) for RNA detection using in vesicle reverse transcription polymerase chain reaction (RT-PCR). We prepared GUVs that encapsulated one-p...
The analysis of microRNA expression patterns provides new insights into numerous cellular processes and their aberrances in diseases. Despite its potential pitfalls, the quantitative real-time polymer...
To determine when Tropheryma whipplei polymerase chain reaction (PCR) is appropriate in patients evaluated for rheumatological symptoms.
We aim to update a meta-analysis to evaluate the efficiency of polymerase chain reaction (PCR) for diagnosis of periprosthetic joint infection (PJI) because different types of PCR assays have yielded ...
A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.
DNA sequences that form the coding region for retroviral enzymes including reverse transcriptase, protease, and endonuclease/integrase. "pol" is short for polymerase, the enzyme class of reverse transcriptase.
Inhibitors of reverse transcriptase (RNA-DIRECTED DNA POLYMERASE), an enzyme that synthesizes DNA on an RNA template.
Methods for using more than one primer set in a polymerase chain reaction to amplify more than one segment of the target DNA sequence in a single reaction.
Methods used for detecting the amplified DNA products from the polymerase chain reaction as they accumulate instead of at the end of the reaction.
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
