Genetic Screening for Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines the link between specific genetic markers and various cancers, such as those affecting the colon, breast, and lungs. Researchers aim to determine if certain genetic patterns are associated with these cancers, potentially aiding future understanding and treatment. The study employs a PCR/PCR/LDR Strategy, a genetic testing method, to analyze these patterns. Participants diagnosed with these cancers who have provided blood samples, particularly those with multiple cancer diagnoses or Ashkenazi Jewish ancestry, may be well-suited for this study. As an unphased trial, it offers a unique opportunity to contribute to groundbreaking research that could shape future cancer treatments.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that the PCR/PCR/LDR Strategy is safe?
Research has shown that the PCR/PCR/LDR method is generally well-tolerated by patients. This technique detects small DNA changes, such as mutations, with high accuracy. Studies have found it effective without harming participants.
The technology identifies specific DNA markers in blood samples. It requires no medications or physical treatments, so no direct side effects have been reported. This makes it a safer choice for participants concerned about negative effects. Essentially, it is a lab test that examines blood for possible cancer-related changes without affecting health.12345Why are researchers excited about this trial?
Researchers are excited about the PCR/PCR/LDR strategy for cancer genetic screening because it offers a more precise method of detecting genetic markers associated with cancer risk. Unlike traditional diagnostic methods that may rely on broader genetic testing or imaging, this approach focuses on identifying specific genetic mutations linked to various cancers, such as colon, breast, and lung cancers. This targeted technique could lead to earlier and more accurate detection, helping individuals understand their cancer risk better and enabling more personalized and timely interventions. By honing in on precise genetic changes, this strategy aims to improve the accuracy of cancer screening and potentially revolutionize how we assess cancer risk.
What evidence suggests that the PCR/PCR/LDR Strategy is effective for genetic screening in cancer?
Research has shown that a method called PCR/PCR/LDR can detect cancer-related changes in DNA even when few cancer cells are mixed with normal cells. PCR, a lab technique, creates many copies of DNA to identify small genetic changes linked to cancer. Some studies have found that it can detect changes in genes like BRCA1 and BRCA2, which increase cancer risk. This method may be particularly useful for detecting cancers such as prostate and breast cancer. By identifying these changes early, PCR methods can help detect cancer sooner, potentially leading to better outcomes. Participants in this trial will be compared to controls, including volunteer blood donors and normal volunteers, to evaluate the effectiveness of the PCR/PCR/LDR strategy in detecting genetic changes associated with cancer.16789

Are You a Good Fit for This Trial?
This trial is for Ashkenazi Jewish individuals with a confirmed cancer diagnosis, including kidney, breast, colon, prostate, lung, ovarian, bladder cancers or lymphoid malignancies. Eligible participants must have donated a blood sample at MSKCC and can have multiple diagnoses of the same cancer type.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- PCR/PCR/LDR Strategy
Trial Overview
The study is exploring if there's a link between inherited genetic variations (germline polymorphisms) and various cancers using PCR/PCR/LDR strategy to analyze DNA. It aims to generate hypotheses for future research rather than test a treatment.
How Is the Trial Designed?
2
Treatment groups
Active Control
Placebo Group
All incident second primary cancers of colon, breast, bladder, kidney, prostate, ovarian cancer lung cancer and lymphoid cancer diagnosed between 1999 and present will be included in the secondary design to compare second primary cancer "cases" and first primary "controls".
Controls will be volunteer blood donors from the New York Blood Center as well as normal volunteers from other AMDeC sites.
