本文对１８例热化疗后和１８例单纯手术的大肠癌标本切片进行了癌组织内淋巴细胞计数；其中９例热化疗病例还进行了热化疗前后的淋巴细胞计数。结果显示热化疗组的癌组织内淋巴细胞数明显高于单术组（Ｐ＜０．０１）。热化疗后的癌组织内的淋巴细胞数也明显高于热化疗前（Ｐ＜０．０１）。本资料结果提示热化疗能提高癌组织内的淋巴细胞浸润程度，而癌组织内淋巴细胞浸润程度增高对病人的预后是会有益的。
In this paper, lymphocyte counts in 18 cases of thermochemotherapy and 18 cases of colorectal cancer specimens undergoing surgery alone were performed. In 9 cases of thermochemotherapy, lymphocyte counts before and after thermochemotherapy were also performed. The results showed that the number of lymphocytes in the cancer tissue of the thermochemotherapy group was significantly higher than that of the single surgery group (P<0.01). The number of lymphocytes in cancer tissue after thermochemotherapy was also significantly higher than before thermochemotherapy (P<0.01). The results of this data suggest that thermochemotherapy can increase the degree of lymphocyte infiltration in cancer tissues, and increased lymphocyte infiltration in cancer tissues is beneficial to the patient’s prognosis.
