Abstract |
PurposeTo review the clinical outcomes of extended-field radiation therapy (EFRT) and to analyze prognostic factors significant for survival in patients receiving EFRT for uterine cervical carcinoma with para-aortic node (PAN) metastasis.Patients and methodsWe retrospectively reviewed 90 patients with stage IB-IVA cervical cancer and PAN metastasis between 1987 and 2012. Median age was 50 (range, 24¿77). Patients received median 70.2 Gy (range, 56¿93) to point A and median 50.4 Gy (range, 45¿60.4) to PAN over median 69 elapsed days (range, 43¿182). Forty-six patients (51.1%) received concurrent chemotherapy. Survival was calculated using the Kaplan¿Meier method. We analyzed prognostic factors for overall actuarial survival (OS) and progression-free survival (PFS) using a Cox regression method.ResultsThe median follow-up period for surviving patients was 55 months (range, 3¿252). Seventy patients (77.8%) had complete remission. Forty-six patients experienced treatment failure as follows: 11 patients (12.2%) as local recurrence, 19 (21%) as regional recurrence and 33 (36.7%) as distant metastasis. The 5-yr OS and PFS were 62.6% and 43.9%, respectively. Treatment response was the only statistically independent prognostic factors for OS (p= 0.04) and PFS (p< 0.001) on multivariate analysis. Grade 3 or 4 hematologic gastrointestinal and urogenital toxicities were observed in about 10% of patients.ConclusionsOur institutional experiences showed that EFRT was an effective treatment for cervical cancer patients with PAN metastasis. The addition of chemotherapy to EFRT seems to have uncertain survival benefit with higher hematologic toxicity. |
