title: The relevance of adjuvant therapy in primary carcinoma of the fallopian tube, stages I and II: irradiation vs. chemotherapy.
abstract: BACKGROUND
  Primary carcinoma of the Fallopian tube (FTC) is a rare but extremely aggressive neoplasm. It must be expected to cause up to 40% of tumor-related deaths even in Stage I, and up to 57% in Stage II. Due to its rarity, there exist only a few and divergent reports on the value of adjuvant therapy. Therefore the present study aims at evaluating the influence of postoperative adjuvant therapy on FTC by studying the effects of irradiation and chemotherapy on the overall survival of patients in Stages I and II.
  
  
  METHODS
  We investigated 95 cases of FTC in Stages I (n = 66) and II (n = 29) in a retrospective multicenter study. Group I (n = 32) are patients who underwent a complete irradiation with cobalt or photon energies of 23 MV (administering a daily dose of 2 Gy resulted in a total of 45-52 Gy in the pelvic areas). Group II (n = 31) consists of those cases who received postoperative chemotherapy with platinum. Thirty-two women were excluded from this study because they had other chemotherapies, incomplete irradiation, or no adjuvant therapy at all.
  
  
  RESULTS
  Median survival time was 57 months in Group I patients (95% confidence interval 33-81 months), compared to 73 months (95% confidence interval, 68-78 months) in the chemotherapeutically treated Group II. This difference did not prove to be statistically significant (p = 0.476).If primary surgical therapy is included in the evaluation, and patients with total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) are compared to those with additional radical lymphadenectomy (TAH+BSO+lymph nodes), the latter group's overall survival essentially improves but fails to reach statistical significance. Their 5-year survival rate is 83% against 58% in the TAH+BSO group (p = 0.12).
  
  
  CONCLUSIONS
  Chemotherapy and irradiation are two adjuvant therapies that are similarly effective in FTC of Stages I and II, with chemotherapy being preferred at the present time. Primary surgical treatment, however, is of crucial impact on the prognosis of FTC.
