The tumor-stroma ratio is an independent predictor of survival in patients with 2018 FIGO stage IIIC squamous cell carcinoma of the cervix following primary radical surgery

Zong L, Zhang Q, Kong Y, et al. - By retrospectively analyzing patients (n = 384) with node-positive squamous cell carcinoma of the cervix (2018 FIGO stage IIIC) who underwent radical surgery between January 2005 and December 2016, researchers assessed the value of the tumor-stroma ratio (TSR) while identifying prognostic factors in these patients. The TSRs were grouped as stroma-low (< 50% stroma) or stroma-high (≥ 50% stroma). Shorter disease-free survival (DFS) and overall survival (OS) periods were noted in stroma-high patients vs their stroma-low counterparts. Independent predictors of shorter DFS and OS in multivariate analysis were: a tumor size ≥ 4 cm, ≥ 3 metastatic lymph nodes, and stroma-high status. Overall, TSR was identified as an independent prognostic factor and a prognostic scoring system including this parameter displayed good discriminative ability for both recurrence as well as survival in this patient population. The TSR was suggested as a potentially new clinicopathological variable for prognosis prediction in these patients contingent on the validation of these findings.
