Identification of prognostic factors in patients with cervical cancer and supraclavicular lymph node recurrence

ObjectivePatients with cervical cancer and supraclavicular lymph nodes (SLN) recurrence have a poor but heterogeneous prognosis. The aim of this study was to identify potential prognostic factors – including FDG-PET results – that may affect survival and treatment outcomes in patients with this group of patients.MethodsBetween January 2001 and December 2008, we identified a total of 31 consecutive patients with cervical cancer who had evidence of SLN recurrence. All participants underwent FDG-PET. Survival was measured from the date of documented SLN recurrence. The latency period was defined as the length of time from the date of first diagnosis to the date of SLN recurrence.ResultsThe median follow-up time was 22.8 months (range: 4.7–105.1). The 3- and 5-year survival rates were 41% and 27.3%, respectively. Patients with intermediate SUV values (between 4.3 and 8) had a significantly better prognosis than subjects with both high (> 8) or low (< 4.3) SUV values (p = 0.004). Latency period < 2 years, SCC-Ag levels ≥ 4 ng/mL, recurrence extend beyond SLN, and SUV of < 4.3 > 8 were significant adverse prognostic factors by multivariate analysis. The 3-year overall survival (OS) rate of patients carrying 0–1 adverse prognostic factors was 90% (low-risk group), while 3-year OS rates for intermediate-risk group (2 factors) and high-risk group (3–4 factors) were 30% and 0%, respectively (p = 0.001).ConclusionOur results justify the use of PET (accurate extent of relapse and SUV) as a prognostic tool in patients with cervical cancer and SLN recurrence.

► Long-term survival may be possible in cervical cancer patients with supraclavicular lymph node recurrence.
► FDG uptake at supraclavicular nodes predicts survival after relapse.
