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 performing this retrospective analysis in patients (n = 384) with node-positive squamous cell carcinoma of the cervix (2018 FIGO stage IIIC) who had radical surgery between January 2005 and December 2016, researchers focused on the worth of the tumor-stroma ratio (TSR) while recognizing prognostic factors in these patients after primary radical surgery. The evaluation of TSRs was done on hematoxylin and eosin-stained tumor slides, followed by grouping as stroma-low (< 50% stroma) or stroma-high (≥ 50% stroma). The factors that were independently predictive of shorter disease-free survival and overall survival were a tumor size ≥ 4 cm, ≥ 3 metastatic lymph nodes, and stroma-high status, as revealed in multivariate analysis. In this study, the TSR was identified as an independent prognostic factor. Furthermore, findings revealed good discriminative ability displayed by a prognostic scoring system including this parameter for both recurrence and survival in patients with 2018 FIGO stage IIIC cervical cancer post-radical surgery. Overall, the TSR represents a potentially new clinicopathological variable for foretelling the prognoses of these patients contingent on the validation of these findings.
