Ultrasonographic appearance of fallopian tube carcinoma

[Ultrasonographic features in the preoperative diagnosis of primitive fallopian tube carcinoma]

OBJECTIVES

To review the characteristic ultrasound features of primary fallopian tube carcinoma (PFTC) and its relationship to the clinical history in order to establish specific findings useful for the preoperative diagnosis.

METHOD

An extensive review of the current literature was done on Medline via PubMed by using the following keywords: "primary fallopian tube cancer", "tubal cancer", "adnexal malignancy mass" and "ultrasound".

RESULTS

PFTC corresponds to complex, sausage-shaped structures or cystic adnexal masses. A thick and an irregular capsule are in favour of a malignant lesion. Three-dimensional ultrasound is superior to 2D ultrasound for the detection of tubal wall irregularities such as papillary projections or pseudosepta who were suggestive of tubal malignancy and allows a better assessment of the extent of tumor infiltration through the capsule. Neovascularization with low resistance indices are typical of tubal malignancy. Three-dimensional power Doppler sonography acutely detected structural abnormalities of the malignant tumor vessels which are randomly dispersed within the papillary projections. Intra-uterine collection and peritumoral fluid are often found but ascite could be also an indirect proof of peritoneal carcinosis.

CONCLUSION

Sausage-shaped structures or cystic adnexal masses associated with imaging findings such as papillary projections and neovascularization with low resistance indices are in favour of PFTC. A standardized terminology, high-frequency and 3D power Doppler could improve diagnostic performance by allowing a better assessment of tubal wall and chaotic vessels architecture of these tumors.

Analysis of treatment failures and survival of patients with fallopian tube carcinoma: a cooperation task force (CTF) study

OBJECTIVE

The objective of this retrospective multicenter study was to assess the pattern of failures and survival of patients with primary carcinoma of the fallopian tube.

METHODS

The hospital records of 88 patients with primary carcinoma of the fallopian tube were reviewed. Surgery was the initial therapy for all patients. Tumor stage was I in 21 (23.9%), II in 21 (23.9%), III in 43 (48.8%), and IV in 3 (3.4%) patients. Postoperative treatment was given without well-defined protocols. The median follow-up of survivors was 55 months (range, 7-182).

RESULTS

Of the 21 patients with stage I disease, 10 had no postoperative treatment and 11 had platinum-based chemotherapy. Five (23.8%) patients recurred after a median of 29 months (range, 8-93) from initial surgery. Of the 21 patients with stage II disease, 2 had no postoperative treatment, 2 underwent external pelvic irradiation, 16 received platinum-based chemotherapy, and 1 patient had oral melphalan. Eight (38.1%) patients recurred after a median of 25.5 months (range, 7-57). Of the 46 patients with stage III-IV disease, 1 patient refused chemotherapy and died after 19 months and 45 patients received platinum-based chemotherapy. A clinical complete response was obtained in 29 (64.4%) patients and a partial response in 8 (17.8%). A second-look laparotomy was performed in 14 of the 29 clinically complete responders: 12 patients were found to be in pathological complete response and 2 had persistent disease. Six (50.0%) of the former recurred after a median of 22 months (range, 13-101) from initial surgery. The two patients with persistent disease developed tumor progression after 15 and 11 months, respectively. Fifteen clinically complete responders did not undergo second-look, and 7 (46.7%) of them had a recurrence after a median of 18 months (range, 9-41). For the whole series, 5-year survival was 57%. By log-rank test, survival was related to FIGO stage (III-IV vs I-II, P = 0.0001), tumor grade (G3 vs G1 + G2, P = 0.0038), and patient age (>58.5 years vs <58.5 years, P = 0.0069), but not to histological type. The Cox model showed that FIGO stage (P = 0.0018) and patient age (P = 0.0290) were independent prognostic variables for survival. Among the patients with stage III-IV disease, 5-year survival was 55% for the patients who had residual tumor <1 cm compared with 21% for those who had larger residuum (P = 0.0169).

CONCLUSIONS

Primary carcinoma of the fallopian tube shares several biological and clinical features with ovarian carcinoma. However, when compared with the latter, fallopian tube carcinoma more often tends to recur in retroperitoneal nodes and distant sites. Stage, patient age, and, among patients with advanced disease, residual tumor after initial surgery represent important prognostic variables for survival.

Preoperative diagnosis of primary fallopian tube carcinoma

INTRODUCTION

Transvaginal color and pulsed Doppler can detect areas of neovascularization within the tubal carcinoma and can distinguish it from other benign adnexal pathology. SUBJECTS AND METHODS. During a 7-year period eight cases of Fallopian tube carcinoma were detected using transvaginal color and pulsed Doppler.

RESULTS

Transvaginal sonography revealed complex, sausage-shaped, and/or cystic structures in the adnexal region. Additional color Doppler examination depicted low vascular impedance (RI ranged from 0.29 to 0.40). Histopathology reported different types of Fallopian tube carcinoma.

CONCLUSION

Transvaginal color Doppler may aid in diagnosis of Fallopian tube malignancy more reliably than using other costly diagnostic procedures.
