INTRODUCTION: Our paper evaluates the relationship between radiologically abnormal cardiophrenic lymph nodes (CPLN) in advanced ovarian cancer and pattern of disease distribution, tumour burden, surgical complexity, rates of cytoreduction and same-site recurrence. Impact of suspicious CPLN and CPLN dissection on overall survival also determined.
MATERIALS AND METHODS: Retrospective review of index CT imaging for 151 consecutive patients treated for stage III/IV ovarian malignancy in a large UK cancer centre to identify radiologically abnormal CPLN. Corresponding surgical, histo-pathological and survival data analysed.
RESULTS: 42.6% of patients had radiologically 'positive' CPLN on index CT. Radiological identification of CPLN involvement demonstrated a sensitivity of 82% within our centre. Patients with cardiophrenic lymphadenopathy on pre-operative CT had significantly more co-existing ascites (p = 0.003), omental (p = 0.01) and diaphragmatic disease (p < 0.0001). At primary debulking (PDS), suspicious CPLN were associated with significantly higher surgical complexity scores, without feasibility of complete cytoreduction being impacted. Cardiophrenic involvement at initial diagnosis was associated with same-site relapse at recurrence (p = 0.001). No significant difference in overall survival was demonstrated according to CPLN status following either PDS or delayed debulking (DDS). CPLN dissection did not improve patient outcomes.
CONCLUSION: Radiological identification of abnormal CPLN is reliable. Suspicious CPLN appear to represent a surrogate marker of tumour volume - in particular, heralding upper abdominal disease - and should prompt anticipation of high complexity surgery and referral to an appropriate centre. Patients with prior CPLN involvement are more likely to develop same-site recurrence at relapse. Our survival data suggests cardiophrenic LN disease does not worsen patient prognosis and that the therapeutic benefit of CPLN dissection remains unclear.
