我们在研究影响鼻咽癌放疗预后的病理组织学因素时曾注意到癌实质成分的复杂性对患者放疗后的五年生存率有一定影响。“鼻咽恶性肿瘤的命名和分类(草案)”中曾指出:“在分化好的鳞癌切片中,有时也可以见到分化差的病变存在,病理报告中应注明‘部分为分化差的鳞癌’以便于临床追综观察。”本文的目的是进一步研讨不同癌型混合存在的癌实质复杂性的表现对癌的生物学行为及放疗后预后的影响。
When we studied the pathological and histological factors that affect the prognosis of nasopharyngeal carcinoma radiotherapy, we noticed that the complexity of the substantial components of cancer has a certain influence on the five-year survival rate after radiotherapy. “The naming and classification of nasopharyngeal malignancies (Draft)” has pointed out: “In poorly differentiated squamous cell carcinoma sections, poorly differentiated lesions may sometimes be present. The pathology report should indicate that ’partially poorly differentiated’ ”Squamous cell carcinoma“ facilitates clinical follow-up observation.” The purpose of this paper is to further study the effect of the combination of different cancer types on the biological properties of cancer and its biological behavior and prognosis after radiotherapy.
