Treatment of primary fallopian tube carcinoma with cisplatin-containing chemotherapy

Because of the rarity of the primary fallopian tube carcinoma, optimal primary therapy is still not well defined, and there is little information available regarding the efficacy of combination chemotherapy in advanced disease. The experience obtained by treating 14 patients with fallopian tube carcinoma--most of them with advanced disease--using a combination of cisplatin, adriamycin, and cyclophosphamide (CAP) (10 patients) or carboplatin plus cyclophosphamide (4 patients) is reported. One patient had Stage Ic disease, 2 had Stage II, 9 had Stage III, and 2 had Stage IV. Eleven patients had clinically measurable disease (> 2 cm) at the start of chemotherapy. Eight of these patients had a complete clinical response (CR), 2 had partial response (PR), and 1 had progressive disease (PD). Of the 8 CR patients, 5 underwent second-look operation (SLO). Pathological complete response (pCR) confirmed in 4 out of 5 patients at SLO. The 3 patients without measurable disease (< 2 cm) after primary surgery had an indeterminate response to chemotherapy. Two of them (Stages Ic and II, respectively) had a negative SLO, while the third patient with Stage IV disease, who refused the SLO, remains disease-free 41+ months. This high response rate shows that this carcinoma is very responsive to cisplatin- or cisplatin analogue-containing regimens. One pCR and two clinical CR patients relapsed after 20, 14, and 16 months, respectively, from the completion of chemotherapy and died despite the second-line treatment. The toxicity of the regimens was moderate. The median survival was 40 months, and the actuarial 5-year survival rate was 48%. Carcinoma of the fallopian tube appears to respond favorably to cisplatin- or carboplatin-containing chemotherapy.
