Atrial natriuretic factor in gynecologic malignancy.
Abstract
OBJECTIVE: To determine whether plasma atrial natriuretic factor (ANF) levels are different in patients with gynecologic malignancy compared with those in healthy, nonpregnant women, and if differences do exist, whether chemotherapy plays a role. METHODS: We compared the plasma levels of ANF in nonpregnant women free of malignancy (group 1, n = 25) and in patients with malignancy receiving at least one course of platinum-based chemotherapy (group 2, n = 32). To differentiate the contributory role of chemotherapy, another group of patients (group 3, n = 18) was studied before the initiation of chemotherapy. RESULTS: The ANF values (mean +/- standard error [SE]) in groups 1, 2, and 3 were 7.3 +/- 0.3, 13.8 +/- 0.8, and 14.6 +/- 1.8 fmol/mL of plasma, respectively. Significant differences (P < or = .001) occurred between groups 1 and 2 and 1 and 3, but not between 2 and 3. In comparing groups 2 and 3 for a specific type of cancer, there were no significant differences. The respective values (mean +/- SE) for endometrial, ovarian, and cervical cancer before chemotherapy were 9.9 +/- 1.7, 15.05 +/- 2.6, and 18.5 +/- 4.3 fmol/mL. After chemotherapy, the values remained at 9.3 +/- 1.5, 15.03 +/- 1.06, and 14.6 +/- 2.2 fmol/mL, respectively. CONCLUSION: Plasma ANF levels in gynecologic cancer patients were significantly higher than those in healthy, nonpregnant women. Levels were higher before chemotherapy started, thus negating the idea that chemotherapy may initiate the production and release of ANF.
