Patterns of Care
The SEER Patterns of Care (POC) studies provide important information on cancer treatments as documented in hospital records. The study goals are to evaluate the diffusion of state-of-the-art cancer therapy into community practice, disseminate findings in scientific journals and through professional meetings, and work with professional organizations to develop educational opportunities to increase the use of state-of-the-art cancer therapy and quality of care in community practice.
Each year, NCI selects different cancer sites to be included in the POC studies and randomly samples cases from those ascertained by the SEER registries. Cancer sites that have been addressed by POC studies include breast, colorectal, bladder, head and neck, melanoma, non-small cell lung, leukemia, cervical, prostate, pancreatic, testicular, non-Hodgkin’s lymphoma, multiple myeloma, chronic lymphocytic leukemia, vulva, gastric, corpus uteri, sarcoma and ovarian cancers, plus childhood acute lymphocytic leukemia (ALL), acute myelocytic leukemia (AML), Hodgkin’s, osteosarcoma, Ewing’s sarcoma, and brain stem. These studies provide national, population-based information on treatment dissemination into community practice, possible determinants of dissemination, and variations in therapy. This information is vital in developing educational programs designed to improve the quality of cancer care.
The SEER Program provides information that may lead to findings on cancer risk, protective factors, and treatment modalities. The POC studies provide information that may decrease disparities in treatment and survival among different population groups.
