CHI3L1 and neoplasm: Of the 96 women whose residual tumor size was ≤ 1 cm after debulking surgery (Table 2), those with a serous histologic type (0.165 vs. 0.022, p = 0.008) or chemoresistance (0.206 vs. 0.071, p = 0.019) had higher levels of CHI3L1 than those with a non-serous histologic type or chemosensitivity (both by the Student's t-test).
