目的：探讨非肿块型乳腺导管癌数字化乳腺 X 线摄影（DR）表现形式与病理类型的相关性。方法回顾性分析经手术、病理证实的非肿块型乳腺导管癌195例，其中导管内癌36例（1组），导管内癌伴微浸润25例（2组），浸润性导管癌58例（3组），浸润性导管癌伴导管内癌76例（4组），对 DR 表现形式及病灶长径进行对比和统计学处理。结果 DR 表现形式与病理类型关系在总体上差异有统计学意义（P <0.05），χ2分割检验显示导管内癌与浸润性导管癌组及浸润性导管癌伴导管内癌组差异均有统计学意义（ P <0.008），后两组之间差异有统计学意义（ P <0.008），病灶长径与病理类型关系在总体上差异有统计学意义（P <0.05），χ2分割显示导管内癌与浸润性导管癌伴导管内癌组差异有统计学意义（P <0.008），浸润性导管癌与浸润性导管癌伴导管内癌组差异有统计学意义（P <0.008），其他组之间差异无统计学意义（P >0.008）。结论导管内癌 DR 表现形式主要是单纯钙化；以片影伴钙化为表现的，病理类型多是浸润性导管癌伴导管内癌；病灶长径>50 mm，浸润性导管癌伴导管内癌的可能性大。

Objective To investigate the correlation between DR manifestations and pathologic classification of non-mass-like ductal carcinoma of the breast. Methods The clinical data of 195 cases of non-mass-like ductal carcinoma were analyzed retrospectively,included 36 cases of intraductal carcinoma, 25 cases of intraductal carcinoma with microinvasion,58 cases of invasive ductal carcinoma,76 cases of in-vasive ductal carcinoma combined with intraductal carcinoma,which were verified by surgery and patholo-gy. DR manifestations and length of the lesion were comparatively analyzed and statistically processed. Re-sults The correlation between DR manifestations and pathologic classification was significant in general (P < 0. 05). χ2 partition test showed significant differences among intraductal carcinoma,invasive ductal carcinoma and invasive ductal carcinoma combined with intraductal carcinoma(P < 0. 008)and the latter two groups had significant difference(P < 0. 008). Length of lesion and pathologic classification had signif-icant difference in general(P < 0. 05),χ2 partition test showed significant difference between intraductal carcinoma and invasive ductal carcinoma combined with intraductal carcinoma(P < 0. 008)and so as inva-sive ductal carcinoma and invasive ductal carcinoma combined with intraductal carcinoma(P < 0. 008). No significant difference was observed among groups(P > 0. 008). Conclusion The major DR manifestations of intraductal carcinoma were pure calcifications. Lamellar shadow with calcifications tends to be invasive ductal carcinoma combined with intraductal carcinoma. When the length of the lesion is greater than 50mm,it's more likely to be invasive ductal carcinoma combined with intraductal carcinoma.
