Serum ferritin levels in patients with cervical cancer.

Serum ferritin levels were determined by a radioimmunoassay (a 2-site solid-phase method). The mean ferritin level for 52 control women was 35 ng/ml, and the 2nd to 98th percentile reference intervals were 3.9 to 108 ng/ml. The upper limit of ferritin level for controls was determined to be 108 ng/ml, and the sera from cervical cancer patients were screened. In 98 patients with untreated cervical cancer, 50 (51%) had elevated levels of serum ferritin. Among 36 patients who were surgically treated and whose resected specimens were pathologically examined, 12 of 16 patients (75%) with ferritin levels above normal and 3 of 20 patients (15%) with levels below 108 ng/ml had parametrial invasion and/or lymph node metastasis. Serum ferritin levels were measured at 2- to 4-week intervals and 6 months after treatment on 21 patients with levels elevated before therapy. Ferritin levels decreased to the normal range 4 weeks after treatment in many patients, but the development of elevated levels thereafter was closely associated with a poor prognosis. Measurement of serum ferritin may be useful in predicting the extent of cancer beyond the cervix and the prognosis for cervical cancer patients.

67Ga scanning in the evaluation of esophageal carcinoma.

Eighty-nine patients with histologically proved esophageal carcinoma were scanned with 67Ga to screen for extramural tumor extension and lymph-node involvement. Radiation dose and reduction of uptake were correlated. 67Ga accumulation indicated extramural extension with a sensitivity of 67% and a specificity of 93%. Marked uptake in an extraprimary site in the mediastinum or upper abdomen indicated lymph-node involvement with a sensitivity of 27% and a specificity of 100%. Irradiation with more than 20 Gy (2,000 rad) reduced uptake (P less than 0.05). 67Ga scanning appears to be useful in the evaluation of esophageal carcinoma.
