Most cancer patients would opt
for tumor profiling even if the test revealed that they or their families were at risk for other genetic diseases, according to a Yale Cancer Center study.

profile patients»
tumors,» said Razelle Kurzrock, MD, director of the Center
for Personalized Cancer Therapy at UC San Diego Moores Cancer Center.
Traditional genetic approaches together with the new wealth of genomic information
for both human and model organisms open up strategies by which drugs can be
profiled for their ability to selectively kill cells in a molecular context that matches those found in
tumors.
«
For example, it is conceivable to deep - freeze a human
tumor immediately after surgical removal and to precisely determine its biological and pathophysiological
profile with the new method,» explains Pichler.
The 15 AACR scientists, who were already in Washington, D.C., to meet with the U.S. Food and Drug Administration on genetic testing
for cancer patients, tossed around ideas including expanding NCI's
tumor genome - sequencing efforts and getting the government to cover the costs of genomic
tumor profiling.
The study showed that despite the risk
for receiving information about other potentially serious health problems, 59 % of the cancer patients would agree to
tumor profiling if offered by their physician.
«While
tumor profiling holds the promise of improved therapeutics through personalized medicine, it is important that both clinicians and patients discuss the possibilities of incidental findings prior to ordering the testing, as the findings can have serious implications
for both the patient and their family members,» said Melinda Yushak, M.D., M.P.H., first author on the study and a medical oncology fellow in Yale School of Medicine.
Nagrath, director of Rice's Laboratory
for Systems Biology of Human Diseases, said the new metabolic analysis indicates that ovarian cancer may be susceptible to multidrug cocktails, particularly if the amounts of the drugs can be tailored to match the metabolic
profile of a patient's
tumor.
Researchers at Rice University's Laboratory
for Systems Biology of Human Diseases analyzed the metabolic
profiles of hundreds of ovarian
tumors and discovered a new test to determine whether ovarian cancer cells have the potential to metastasize.
In 2011, she joined the institution's molecular diagnostics laboratory where she has been developing translational next generation sequencing assays and bioinformatics workflows
for the Molecular
Tumor Profiling Lab of the Yale Cancer Center.
One project involves probing Foundation Medicine's growing database of
tumor profiles for specific mutations and using that information to either design drugs or to parse patients into clinical trials of the company's drugs, says Pao.
Analyzing the poly - G
profiles of primary and metastatic colon cancer samples from 22 patients revealed that how the primary and metastatic
tumors related to each other was different
for each patient.
Research from Rutgers Cancer Institute of New Jersey examining difficult to treat cancer
tumors through genomic
profiling shows that
tumors with alterations in a signaling pathway responsible
for cell regulation may respond to targeted therapy regardless of where the
tumor originated in the body.
The study wasn't designed to measure whether
tumor profiling made a difference in how patients fared, but «it nonetheless lays the groundwork
for more systematic study of the impact of genomics on clinical practice and patient outcomes,» the report said.
Collaborations to access and
profile immune cells in patient
tumors are also underway to provide the relevant disease context
for our current and future targets.
Using an array of techniques, including RNA sequencing and targeted gene expression
profiling, the researchers searched
for links between gene activity and protein production in these
tumors and the clinical outcomes of patients.

For some types of cancer, the existence of certain subtypes had not been known until researchers began to
profile the genomes of
tumor cells.
It has specialized workflows
for both rare inherited disorders as well as somatic
tumor profiling tests.
To develop the methodology, the group analyzed the molecular
profiles of human embryonic stem cells and compared them with data
for 12,000 samples of 33 different
tumor types held by The Cancer Genome Atlas (TCGA), a U.S. public database.
Examples include the study of allelic variation in the human genome and the development of computational methods
for the discovery of cancer - associated genes and diagnostic cancer markers using genomic
profiles derived from different
tumor types.
He also observed that dietary protein stimulated
tumor growth, but that when restricted
for a short period (6 - 12 weeks), the immune
profile changed and the white T - cell count improved.
While not diagnostic
for SCC, the diagnostic work - up includes complete blood count and serum chemistry
profile, lymph node assessment via cytology, and chest x-rays in order to confirm that the
tumor SCC is confined to the mouth.
Because of the nature of this
tumor, laboratory testing (complete blood count, biochemistry
profile, and urinalysis) and diagnostic imaging (radiographs and ultrasound) are important tests to screen the body
for tumor involvement.
Changes in serum biochemistry
profile for dogs with hepatic
tumors may also indicate hypoglycemia, hypoalbuminemia (levels of albumin in blood serum are abnormally low), hyperglobulinemia (condition characterized by large amounts of globulins [any class of proteins not soluble in water but soluble in saline solution] in blood) and increased pre and post prandial bile acids (before and after eating a meal).
