BACKGROUND Twenty-seven ovarian cancer patients who failed chemotherapy entered a phase I/II trial of intraperitoneal 177Lu-CC49 antibody. METHODS Patients had disease confined to the abdominal cavity +/- retroperitoneal lymph nodes, adequate organ function, and no previous radiation. RESULTS The most common side effects were delayed, transient arthralgia (10/27) and marrow suppression with 1.665 GBq/m2 (45 mCi/m2), which was considered the maximum tolerated dose. One of thirteen patients with gross disease had >50% tumor reduction after therapy, whereas most others with gross disease progressed (one went off study with stable disease at 11 weeks). Seven of nine patients with <1-cm nodules progressed in < or =21 months, and two of nine remain without evidence of disease at 4 to 5 months. Of patients with microscopic or occult disease, one relapsed at 10 months and four of five remain without evidence of disease at >6 to 35 months. CONCLUSIONS Marrow suppression was the dose-limiting toxic effect of intraperitoneal immunotherapy with 177Lu-CC49. Antitumor effects were noted against chemotherapy-resistant ovarian cancer, even at lower dose levels, and resulted in prolonged disease-free survival of most patients with microscopic disease. This form of treatment deserves further study.

D001853 Bone Marrow The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.
