Abstract

OBJECTIVES:

This study aimed to evaluate the efficacy of radiation therapy for pelvic lymph node metastasis from uterine cervical cancer and identify an optimal radiation regimen.

METHODS:

A total of 111 metastatic pelvic lymph nodes, ranging from 11 to 56 mm (median, 25 mm) on CT/MRI, in 62 patients with uterine cervical cancer were treated initially with curative radiation therapy, with 46 patients receiving concurrent chemotherapy. Total radiation doses ranged from 45 to 61.2 Gy (median, 50.4 Gy) in 1.8-2 Gy (median, 1.8 Gy) fractions.

RESULTS:

At a median follow-up of 33 months, 46 of the 62 patients survived. Only 2 irradiated lymph nodes, 24 and 28 mm in diameter, in 1 patient progressed after irradiation alone with 50.4 Gy in 1.8 Gy fractions. All 33 metastatic lymph nodes ≥ 30 mm in diameter were controlled by irradiation at a median dose of 55.8 Gy. The 3-year lymph node-progression free rates were 98.2% in all 62 patients and 98.0% in all 111 metastatic lymph nodes. Except for transient hematologic reactions, 2 patients developed grade ≥ 3 therapy-related toxicities, 1 with an ulcer and the other with perforation of the sigmoid colon. In addition, 2 patients experienced ileus after irradiation.

CONCLUSIONS:

Radiation therapy effectively controlled pelvic lymph node metastases in patients with uterine cervical cancer, with most nodes <24 mm in diameter controlled by total doses of 50.4 Gy in 1.8 Gy fractions and larger nodes controlled by 55.8 Gy, particularly with concurrent chemotherapy. Higher doses to metastatic lymph nodes may increase intestinal toxicities.
