Serum and tissue ferritins were quantitated by a radioimmunoassay kit (SPAC KIT, Daiichi Radioisotope Lab.) and a diagnostic implication of serum ferritins in patients with gynecological diseases was evaluated. In order to investigate the potential use of tumor marker as a feto-placental antigen (protein), ferritin from ovarian cancer was compared with ferritins from normal adult and feto-placental organs. Serum ferritin levels were significantly higher (p less than 0.01) in patients with ovarian adenocarcinoma, Krukenberg's tumor, cervical squamous cell carcinoma and other malignant diseases than in normal women. Among adult organs the kidney and spleen showed the highest and the heart the lowest ferritin content. The ferritin contents of the kidney and spleen were 78.4 micrograms and 76.2 micrograms/g wet weight, respectively and that of the heart was 5.7 micrograms/g wet weight. The ferritin contents of other adult organs ranged from 10 to 25 micrograms/g wet weight. On the other hand the placenta showed the highest and the heart and stomach the lowest ferritin content among feto-placental organs. The ferritin content of the placenta was 7 micrograms/g wet weight. The ferritin contents of other fetal organs were only half as in the placenta. The ferritin contents of ovarian cancers ranged 6 to 8 micrograms/g wet weight and was almost identical to that of the placenta.

This study was designed to investigate the usefulness of serum ferritin determinations for the diagnosis of cervical squamous cell carcinoma. The origin of ferritin in the circulation of these patients was also studied by an in vitro incubation system. Ferritin levels were determined by a radioimmunoassay kit (SPAC kit, Daiichi Radioisotope Lab.). Pretreatment serum ferritin levels were significantly higher (p less than 0.05) in patients with cervical squamous cell carcinoma, ovarian carcinoma, hepatitis and anemia than in normal women. All cases with endometrian cancer showed normal ferritin levels. Among patients with cervical squamous cell carcinoma, stage IV and recurrence groups showed higher ferritin levels than other stages. In vitro incubation studies revealed that squamous cell carcinoma could release significantly larger amount of ferritin than normal squamous epithelium. In addition, circulating and tissue ferritin of squamous cell carcinoma had the same immunological behavior in a ferritin radioimmunoassay, and also showed the identical localization on isoelectrofocusing gels. These results indicated that (1) circulating ferritin in patients with squamous cell carcinoma would, at least in part, be derived from the tumor tissue, and (2) serum ferritin determinations would be useful for the management of patients with cervical squamous cell carcinoma.
