The aim of the present study was to investigate if there is a possible lateralisation for ovarian cancers, to re-examine left-right asymmetry in pelvic lymph nodes distribution in patients with ovarian cancer, and to investigate if pelvic lymph node involvement by metastatic invasion of ovarian cancer cells is ipsilateral or contralateral. There was right-sided lateralisation for ovarian cancer. The numbers of external iliac and hypogastric+obturator lymph nodes were higher on the right side in patients with ovarian cancer on the right side; but they were about equal for right and left sides in patients with ovarian cancer in their left side. The numbers of external iliac and hypogastric+obturator lymph nodes involved by metastatic cancer cells were higher on the right side in patients with ovarian cancer on the both right and left sides. This case may result from the stronger cell-mediated immune activity in the left sides of humans.

卵巢癌右侧偏侧化和卵巢癌细胞累及盆腔淋巴结的右偏角不对称。

本研究的目的是调查卵巢癌是否可能发生侧支化，重新检查卵巢癌患者盆腔淋巴结分布的左右不对称性，并调查是否转移性浸润累及了盆腔淋巴结卵巢癌细胞是同侧或对侧的。卵巢癌有右侧偏侧化。右侧卵巢癌患者右侧of外和下胃+闭孔淋巴结数目较高。但卵巢癌患者的左侧和右侧大致相等。卵巢癌患者右侧和左侧的转移性癌细胞累及的external外和胃下+闭孔淋巴结的数目较高。
