下列关于恶性肿瘤分期的描述错误的是（）。
A.T代表原发肿瘤
B.N代表区域淋巴结受累情况
C.M代表远处转移
D.T1N1M1表示肿瘤处于早期
E.T4N3M1表示肿瘤处于晚期
参考答案：D
解析：肿瘤分期目前国际上广泛采用TNM分期系统。T指肿瘤原发灶的情况，随着肿瘤体积的增加和邻近组织受累范围的增加，依次用T1～T4来表示；N指区域淋巴结受累情况，未受累用N0表示，随着淋巴结受累程度和范围的增加，依次用N1～N3表示；M指远处转移（通常是血道转移），没有远处转移者用M0表示，有远处转移者用M1表示。在此基础上，用TNM三个指标的组合划出特定的分期。无论原发肿瘤大小、淋巴结受累多少，只要已有远处转移即M1，均为处于晚期肿瘤。
