摘要：

Invasive cribriform carcinoma (ICC) is a rare histologic subtype of breast cancer. We aimed to investigate the clinicopathological characteristics and survival outcomes of ICC.
Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified 233,337 female patients diagnosed with ICC (n=618) or infiltrating ductal carcinoma (IDC) (n=232,719). Univariate and multivariate survival analyses were utilized to calculate and compare disease-specific survival (DSS) and overall survival (OS). A 1:1 paired match was carried out on age, tumor stage, tumor grade, estrogen receptor (ER) status, and progesterone receptor (PR) status. Baseline characteristics and survival outcomes were also analyzed in ER-positive tumors. Subgroup analyses summarized the hazard ratio (HR) of IDC versus ICC using a forest plot.
ICCs presented smaller size, lower grade, higher ER and PR positive rate, less nodal metastasis, and were less likely to be treated with mastectomy compared to IDCs. Five-year DSS rates were significantly better for patients with ICC than for patients with IDC (98.8% vs. 93%, P<0.001). Five-year OS rates were 95.3% versus 90.1% (P<0.001). After adjustment for common clinicopathological factors in the multivariate analysis, patients with ICC showed limited DSS advantage over the IDC group (HR=0.75, 95% CI: 0.38-1.51, P=0.421). No significant difference in DSS nor OS was observed in matched groups between ICC and IDC. Analysis among ER-positive patients revealed similar prognostic factors as among all patients. Survival analysis in different tumor grade subgroups showed no significant difference between ICC and IDC.
ICCs have unique clinicopathological characteristics, higher rates of breast-conserving surgery, and more favorable prognosis compared to the overall IDC population. Difference in tumor grade between the 2 groups may partially explain the different outcome. Improved clinical and biological understanding of ICC might lead to more individualized and tailored therapy for breast cancer patients.
