Survival of Cervical Cancer Patients Presenting with Occult Supraclavicular Metastases Detected by FDG-Positron Emission Tomography/CT: Impact of Disease Extent and Treatment.

ABSTRACT

AIMS: The study aimed to do the following (1) describe progression free survival (PFS) and overall survival (OS) of women with cervical cancer presenting with occult supraclavicular lymph node (SCLN) metastases, identified by positron emission tomography CT (PET-CT) and (2) compare OS of patients with isolated SCLN metastases to that of patients with SCLN and extranodal metastatic disease. METHODS: Patients were identified retrospectively. Treatment intent was abstracted. PFS and OS in the high-dose chemo-radiotherapy (RT), palliative RT, and supportive treatment groups, as well as OS of patients with SCLN metastases only vs. SCLN and extranodal metastases were calculated. RESULTS: Fourteen patients received high-dose chemo-RT, 32 received palliative RT, and 6 received supportive care (n = 52). Median PFS was 3 months in high-dose chemo-RT group and 1 month in palliative RT (p = ns). Median OS was 12 months in high-dose chemo-RT group, 7 months in palliative RT group, and 2 months in palliative care group (p = 0.05). OS was significantly different between patients with isolated SCLN disease vs. SCLN and extranodal disease, that is, 10.5 vs. 3 months (p = 0.009, χ2 = 6.9). CONCLUSIONS: In this limited analysis, median OS of cervical cancer patients with PET/CT-positive SCLN metastases was the longest when treated with high-dose chemo-RT. Patients with SCLN and extranodal metastases experienced significantly shorter OS, as compared to patients with SCLN only disease.
