- W4308532035 abstract "Objective. The current guidelines for cervical cancer are uncertain regarding whether the para-aortic lymph nodes (PALNs) need to be removed. For patients with negative PALNs, whether the addition of PALN dissection (PALND) can be translated into survival benefits is unknown. Methods. The medical records of 3,995 patients with FIGO stage IB-IIA cervical squamous cell carcinoma (CSCC) who underwent abdominal radical surgery between 2006 and 2014 at our center were retrospectively reviewed. Two groups were identified: PALN-negative patients who underwent PALND (+PALND) and those who did not (−PALND). The groups were matched by propensity score matching (PSM). Survival was analyzed using the Kaplan–Meier method and the Cox proportional hazards model. Subgroups were stratified by the variables known at the time of diagnosis. Results. After PSM, 313 patients were matched to the −PALND (cohort 1) and +PALND (cohort 2) groups. Cohort 2 patients had a poorer prognosis than cohort 1 patients in terms of overall survival (OS, <math xmlns=http://www.w3.org/1998/Math/MathML id=M1> <mi>P</mi> <mo>=</mo> <mn>0.014</mn> </math> ), and PALND was an independent prognostic factor for OS ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M2> <mi>P</mi> <mo>=</mo> <mn>0.021</mn> </math> ). There were no differences in recurrence patterns between the groups. Subgroup analysis showed that cohort 2 patients had worse OS than cohort 1 patients when they were aged ≤47 years ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M3> <mi>P</mi> <mo>=</mo> <mn>0.033</mn> </math> ), were premenopausal ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M4> <mi>P</mi> <mo>=</mo> <mn>0.032</mn> </math> ), were in stage IB ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M5> <mi>P</mi> <mo>=</mo> <mn>0.009</mn> </math> ), or had preoperative SCC-Ag<6.5 ( <math xmlns=http://www.w3.org/1998/Math/MathML id=M6> <mi>P</mi> <mo>=</mo> <mn>0.009</mn> </math> ). Conclusions. PALND negatively impacts OS in early-stage PALN-negative CSCC patients. For CSCC patients who are clinically PALN-negative, especially those who are young, are premenopausal, have tumors confined to the cervix, and have relatively low SCC-Ag values, PALND may “rub salt on the wound.”" @default.
