The use of bevacizumab in second or later lines remained of borderline significance in the multivariable model (HR 0.69; p = 0.062) ( Table 5 ). 4.

Lung metastasis showed borderline significance (HR 1.34; p = 0.071), and the use of bevacizumab in second or later lines showed a trend toward reduced mortality (HR 0.70; p = 0.066).
Peritoneal metastasis ( p = 0.693), de novo metastatic disease ( p = 0.264), and MSI-H status ( p = 0.074) lost statistical significance, while liver metastasis showed borderline significance (HR 1.62; p = 0.079) ( Table 3 ).
In the mucinous subgroup, irinotecan-based regimens were associated with numerically longer PFS; however, this difference did not reach statistical significance (24.1 vs. 16.2 months; p = 0.190).
