Trial Information

A Retrospective Review of Malignant Liver Tumors

Subjects will be identified by diagnosis and procedure codes from a university surgical
practice and the St. John Medical Center Cancer Registry. Data will be obtained by review
of both the clinic and hospital charts. In addition we plan to review and utilize liver
tumor treatment and outcomes data from a national database. Treatment decisions, in cases
managed by the primary investigator, were made on a clinical basis, often in collaboration
with an interventional radiologist. Of the patients managed by the principal investigator,
all procedures were undertaken after an informed consent process. Subjects were not exposed
to risk beyond that posed by the recommended treatment. All treatments were within the
scope of standard medical care. The primary investigator has no knowledge of the treatments
chosen for the patients he did not manage. The subject's referring physician may be
contacted to obtain follow-up data on the subject. The follow-up data will include: is the
patient alive with disease; alive without disease, alive unknown; dead free of disease; dead
with disease; dead unknown.
