PRIMARY FALLOPIAN-TUBE CARCINOMA - A RETROSPECTIVE SURVEY OF 51 CASES

Objective: To evaluate retrospectively the importance of invasion beyond the basement membrane on overall survival in Fallopian tube carcinoma and its influence on the necessity of postoperative adjuvant therapy (stage 0 vs. stage I). Design: In a nationwide analysis the data of 51 patients were evaluated. The participating departments provided the study center with histologic specimens. A re-staging was done according to the FIGO-classification for Fallopian tube carcinomas. Stage 0 patients received no further postoperative therapy, in stage I patients were devided in 2 groups to evaluate the impact of postoperative adjuvant therapy (chemotherapy vs. irradiation). Results: Patients of stage 0 had a significantly better prognosis than patients of stage I (p = 0.035). Stage I patients treated by irradiation showed a significantly better prognosis than patients treated by chemotherapy (p = 0.017). Conclusion: Tumour penetration through the basement membrane causes prognosis to deteriorate significantly (5-year survival rate about 50% in stage I). Postoperative therapy is thus indicated with stage I disease. Irradiation seems to give better results than chemotherapy.
