Kita-Kyushu lung cancer antigen-1 expression in initial gastric tumors predicts multiple cancer development: A pilot study

Figure 1 Immunohistochemical staining of Kita-Kyushu lung cancer antigen-1 with Kmab34B3 of tumor cells in gastric cancer. A: Negative staining; B: Negative staining. Magnification: 100 ×.

Figure 2 The expression of Kita-Kyushu lung cancer antigen-1 was evaluated in the tumor areas of each gastric cancer patient. Open squares indicate negative results, closed squares indicate positive results, and an X indicates cases that could not be tested. The tumor areas were divided into three parts: Upper, middle, and lower. U: Upper; L: Low; M: Middle.
