Brief Summary
This research trial studies germ-line mutations in blood and saliva samples from patients with cancer. Studying samples of blood and saliva from patients with cancer in the laboratory may help doctors learn more about how inherited genetic mutations can affect cancer predisposition (an inherited increase in the risk of developing cancer), their impact on treatment response, and their role in cancer development.

Outcome Measures
Primary Outcomes (4)
Prevalence of germ-line variants
The prevalence of germ-line variants of interest will be compared to the baseline prevalence found using available large human genomic DNA collections. The primary statistical analysis will involve comparisons of genotypes between with (cases) and without (controls) the germ-line mutation. This analysis will include Pearson's chi-square analysis or Fisher's exact test and computation of odds ratios to assess the relationship of the genetic polymorphism and cancer risk.
Up to 5 years
Overall genotype frequencies
The overall genotype frequencies among the cases and expected control levels will first be compared with the frequencies expected from Hardy-Weinberg equilibrium by goodness-of-fit chi-square. Odds ratios and 95% confidence intervals will be used to estimate risk associated with the variant genotypes by using both univariate and unconditional multivariate logistic regression models.
Up to 5 years
Response to treatment
The impact of inherited variants on response to treatment will be determined.
Up to 5 years
Cancer development
The role of inherited variants in clinical and pathological cancer development will be determined.
Up to 5 years
Study Arms (1)
Ancillary-Correlative (germ-line mutation analysis)
Patients undergo collection of blood and saliva samples 1-3 times at the discretion of the investigator for germ-line mutation analysis.
Interventions
Correlative studies
