Purpose: To develop an MRI-based multiregional radiomics model for the noninvasive desmoplastic reaction (DR) classification and prognosis stratification in stage II rectal cancer (RC) patients.
Materials And Methods: This study retrospectively involved 336 patients with RC from two centers, with 239 from Center 1 divided into training (n = 191) and internal validation (n = 48) datasets at an 8:2 ratio, and 97 from Center 2 serving as external validation dataset. Radiomics features were extracted, and a multiregional radiomics DR (M-RDR) signature was established using multi-level feature selection procedure.

Context.—: Lymph node (LN) involvement (LNI) is not infrequently observed in ovarian serous borderline tumors (SBTs) but is not considered equivalent to malignant tumor metastasis, as it reportedly does not impact recurrence or survival in patients with SBT. However, the reasons underlying the insignificant clinical impact of LNI remain unclear.

Background: Desmoplastic reaction is recognized as a prognostic factor in colorectal cancer. However, its significance in locally advanced rectal cancer following neoadjuvant chemoradiotherapy remains underexplored.
Objective: To assess the prognostic value of desmoplastic reaction in specimens from patients with advanced rectal cancer after chemoradiotherapy.
