Figure 2From: Stromal micropapillary component as a novel unfavorable prognostic factor of lung adenocarcinomaVenn diagram of patients included in the present study. Among the 559 cases of lung adenocarcinoma, 104 cases had MPC. Nineteen cases had SMPC (SMPC(+) tumors, the area enclosed by continuous line), and 99 had AMPC (AMPC(+) tumors, the area enclosed by dotted line). A mixture of SMPC and AMPC was observed in 14 patients, SMPC without AMPC in 5 and AMPC without SMPC in 85. MPC, micropapillary component; SMPC, stromal micropapillary component; AMPC, aerogenous micropapillary component.Back to article page
