Objective: A phase II trial on neoadjuvant trans-uterine arterial chemotherapy (TUAC) followed by type III radical hysterectomy (RH) was conducted for patients with bulky cervical adenocarcinoma (AC).
Methods: Tumors of >4 cm were eligible. The neoadjuvant regimen comprised paclitaxel (60 mg/m(2) intravenously on days 1, 8, and 15) and cisplatin (70 mg/m(2) TUAC followed by transcatheter embolization with gelatin sponge particles on day 2) repeated every 3 weeks for 3 cycles. The primary endpoints were clinical and pathological responses.
Results: Twenty-two patients (median age, 51 years; range, 33-75 years) were enrolled. The International Federation of Gynecology and Obstetrics stages were IB2 (9 patients), IIA-IIB (8), IIIB (3), and IVA (2). The adeno/adenosquamous ratio was 16/6. The overall clinical response rate was 95.4% (95% confidence interval [CI], 86.7-100%). RH was completed in 19 patients (86%), including 2 stage IVA patients who underwent anterior or posterior pelvic exenteration. Of the 19 patients, no residual malignant cells were found pathologically in 4; thus, the pathological complete response rate was 18% (4/22). No patients experienced grade 4 thrombocytopenia or febrile neutropenia or required platelet transfusions. The 5-year progression-free survival and overall survival rates in stages IB2-IIB were 70.0% (95%CI, 48.1-92.1%) and 69.5% (95%CI, 47.0-92.0%), respectively. The 2 patients with stage IVA tumors were alive without recurrence for 72 and 84 months after enrollment.
Conclusions: TUAC showed high clinical and pathological response rates. TUAC is promising for stage IB2-IIB and IVA bulky AC.
