摘要
目的通过对0～Ⅰ期(早期)乳腺癌病例的钼靶X线、超声及临床查体特点的分析,探讨乳腺癌的早期发现方法。方法经手术病理证实的28例0～Ⅰ期乳腺癌术前均行临床查体、双侧钼靶X线摄片和全乳腺超声扫描。结果临床查体对0～Ⅰ期早期乳腺癌的诊断符合率为57.1%(16/28),超声、钼靶X线摄片可达85.7%(24/28)和89.3%(25/28)。早期乳腺癌临床表现仍以乳腺内肿块为主,占诊断阳性病例的87.5%(14/16),X线摄片特点以结节肿块影为主,占56%(14/25),低回声实性占位为早期乳腺癌主要的超声特点,所占比例为占75%(18/24)。8例0期乳腺癌中,X线摄片诊断符合率为100.0%(8/8),超声和临床查体均为50%(4/8),以钼靶摄片上的恶性钙化为其主要表现。超声诊断Ⅰ期乳腺癌的符合率为100.0%(20/20),X线摄片、临床查体分别为85.0%(17/20)和40%(8/20),超声检查对于年轻、致密性腺体具有优势。结论早期乳腺癌无论在临床表现、影像学检查均可出现不典型特征,乳腺X线摄片、超声及临床查体是早期发现乳腺癌的重要手段,诊断时又各有疏漏,应综合考虑,互相弥补,当其中一项高度疑为乳腺癌时,均应予以重视,及时明确诊断。
Objective To study the features of mamrnography, breast ultrasonography （US） and physical examination （PE） on 0-Ⅰ stage （early stage） breast cancer, and to approach a diagnostic measure for early stage breast cancer （EBC）. Methods Physical examination, ultrasonography and mamrnography were performed in 28 patients with pathologically proved breast cancer in 0-Ⅰ stage, and the data were analyzed. Results The accuracy of PE for 0-Ⅰ stage of EBC was 57.1% （16/28）, and the accuracy by US or mamrnography was 85. 7% （24/28） and 89. 3% （25/28）, respectively. As the main clinical symptom of 0-Ⅰ stage EBC, breast lumps were found in 14 of 16 PE positive cases （87. 5%）. The main feature of EBC by rnamrnography was the finding of a lump （14/25, 56%）. The low echo of a solid space occupying lesion was the main US feature of E/3C （18/24, 75%）. The diagnostic accuracy of mammography for 0 stage EBC was 100. 0% （8/8）, while only 50% （4/8） by both US and PE. Malignant calcification was the main feature of o stage breast cancer in mammography. The diagnostic accuracy of US, mamrnography and PE for Ⅰ stage EBC was 100. 0% （20/20）, and was 85.0% （17/20） and 40% （8/20）, respectively. US was advantagious in detecting cancer in young patient with compact breast. Conclusion Early stage breast cancer often displayed atypical features in PE, US and mammography, which are important for the early-diagnosis of breast cancer, and false negative findings are inevitable in examination. Therefore, the diagnosis of early stage breast cancer should be made with. The find ings of PE, US and mamrnography should be analyzed comprehensively, however, when one of examinations gives a positive finding, the diagnosis of breast cancer should be suspected, and further examination should be carried out to make an early diagnosis.
