Genetic Risk of Osteonecrosis of the Jaw (ONJ) in Patients With Metastatic Cancer
Studieöversikt
Status
Detaljerad beskrivning
The goal of this research is to build an index of risk for estimating an individual's risk of developing osteonecrosis of the jaw (ONJ). The bisphosphonates are an important supportive therapy in the care of patients with metastatic bone disease; they are able to prevent catastrophic events such as fracture and spinal cord compression. However, ONJ has been associated with the use of the bisphosphonates and ONJ carries significant morbidity. Presently, there are insufficient data to calculate the ONJ risk benefit ratio of bisphosphonate use. An ONJ risk assessment tool would improve both the oncologist's and the dental health professional the ability to anticipate and potentially mitigate oral toxicities from bisphosphonate therapy.
This protocol consists of a case (ONJ) control (no ONJ) study to identify factors associated with the risk of ONJ and to build an index predictive of an individual's risk of developing ONJ. The index of ONJ risk will be comprised of clinical, epidemiologic and genetic factors

Beskrivning
Inclusion Criteria:
- The study candidate must have sufficient Formalin Fixed Paraffin Embedded (FFPE)Specimens (lymph node or tumor) for DNA extraction available for study SNP assessment
- Patients over the age of 21 with a histologically confirmed diagnosis of cancer who have received nitrogen containing bisphosphonate therapy for metastatic bone disease.
- FFPE tissues are to have been removed for clinical indication and sufficience study volume of specimen must be available in an established tissue repository.
- Study FFPE tissues include:
- formalin fixed paraffin embedded leukocytes from lymph nodes with or without involvement by tumor AND/OR
- formalin fixed paraffin embedded tumor tissue (tumor block without invasive cancer is acceptable if the specimen is believed to be sufficiently cellular (breast tissue or noninvasive cancer) to yield adequate DNA)
- Medical records available for data abstraction
Exclusion Criteria:
- Insufficient specimen available to perform the assays proposed for specimen DNA analysis
- No accessable medical records
