To establish prognosis, histologic appearance and p53 and c-erbB-2 expression in cancer tissue, six cases of primary transitional cancer of the fallopian tube were analyzed. Among 45 patients with the primary cancer of the fallopian tube diagnosed between 1992 and 1997, we found six cases diagnosed previously as solid (undifferentiated) cancer of the tube. p53 protein and c-erbB-2 oncoprotein expression were examined using an avidin-biothinyl-peroxydase complex method. The accumulation of p-53 protein and c-erbB-2 oncoprotein were used as prognostic marker of the transitional cancer of the tube. According to histologic picture all patients were diagnosed for primary cancer of the tube with transitional differentiation. In 4 cases strong positive and in 2 cases moderate positive reaction with antibody against p53 protein was seen for p53 protein. No positive expression of c-erbB-2 oncoprotein in membrane of cancer cells in our cases was detected. Presence p-53 protein in all our 6 cases deny the usefulness of the p53 protein as prognostic marker in primary cancer of the fallopian tube. Lack of expression of c-erbB-2 oncoprotein in membrane of cancer cells is significantly contributed to better prognosis in cases with primary cancer of the tube with transitional differentiation.

Serum CA 125 levels were evaluated in 26 patients with fallopian tube malignancies. CA 125 was elevated preoperatively in seven samples (median 178 U ml-1 range 41-19021 U ml-1), and postoperatively in eight of nine (89%) samples collected from patients with residual disease (median 109 U ml-1 range 10-1883 U ml-1) but only in one of seven (14%) samples from patients without residual disease (median 14, range 5-170 U ml-1) (P < 0.001). Changes in the serum CA 125 level during chemotherapy correlated with the clinical course of disease in 13 of 14 patients with a pre-chemotherapy serum CA 125 level> 35 U ml-1. Nine patients with clinical remissions showed decreasing serum CA 125 levels, one with clinically stable disease showed decreasing levels and four with disease progression showed increasing levels. Serum CA 125 levels were measured in four patients before second-look laparotomy. Two of three with positive findings at laparotomy had elevated serum CA 125 levels whilst the third had a normal level. One patient with negative findings at second-look surgery had a normal CA 125 level. Disease relapse was associated with elevated serum CA 125 levels in nine of 10 patients (median 108 U ml-1, range 27-38200 U ml-1). Using immunohistochemical staining, none of the tumors showed positive cytoplasmic staining for c-erbB-2 (NEU) oncogene. This report shows that CA 125 is a reliable tumor marker for monitoring patients with cancer of the fallopian tube during active treatment and follow-up.
