Patterns of treatment failure following radiotherapy with combination chemotherapy for patients with high-risk stage IIB cervical carcinoma.
BACKGROUND
To evaluate the patterns of treatment failure in patients with stage IIB cervical carcinoma with high-risk factors following radiotherapy given concurrently with combination chemotherapy.


METHODS
A retrospective analysis of 349 patients with stage IIB cervical carcinoma with high-risk factors (lesion size >/= 4 cm, lymph node metastasis, high-risk cell type) treated by radiotherapy and cisplatin-based chemotherapy was performed. Sites of treatment failure were categorized as pelvic, pelvic plus distant metastases, and distant metastases alone. Pelvic failure included local and pelvic nodal failures.


RESULTS
Of the 349 patients, treatment failure occurred in 79 patients (22.6%). Forty-six (13.2%) had persistent disease and 33 (9.5%) had recurrent disease. Among these 79 patients, overall pelvic failure was observed in 67%, of whom 72% had local failure; 19%, pelvic nodal failure; and 9%, local with pelvic nodal failure. Incidences of distant metastases alone and pelvic with distant metastases were 24% and 9%. In the 26 patients with distant metastases either alone or combined with pelvic failure, the most frequent metastatic region was the paraaortic lymph node (50%). The distant metastasis rate was 6.5% (19/289) in the pelvic tumor control group and 11.6% (7/60) in the pelvic failure group. Pelvic failure was the most frequent failure in the group with tumor size of 4 cm or more, whereas, for the positive-lymph-node group, distant metastasis was most frequent and metastases to paraaortic lymph nodes were common. The incidences of pelvic failure alone and distant metastases were similar in the high-risk cell-type group, and the distant metastasis regions were mostly paraaortic lymph nodes.


CONCLUSIONS
Although systemic chemotherapy was administered concurrently with radiotherapy, the incidence of pelvic failure was highest, followed by paraaortic lymph node metastases, in patients with stage IIB cervical carcinoma with high-risk factors, following radiotherapy with combination chemotherapy. To evaluate the patterns of treatment failure in patients with stage IIB cervical carcinoma with high-risk factors following radiotherapy given concurrently with combination chemotherapy.
