目的 评价近红外光扫描诊断乳腺癌的意义 .方法 将近红外光扫描诊断为乳腺癌的 1 72例患者与术后病理诊断对照 .结果 近红外光扫描诊断乳腺癌的正确率为91 .3% .肿块长径在 2～ 5 cm及 >5 cm者 ,其诊断正确率为95 .4%和 1 0 0 % ;<2 cm者 ,则为 74.4% ;并检出 2例临床无明显包块的早期乳腺癌 . 1 5 7例病理确诊的乳腺癌 ,40～ 5 0岁发病率最高 (31 .2 % ) ,其次为 30～ 40岁组 (2 8.7% ) .近红外光扫描图像灰影伴血管改变越明显 ,该肿瘤也越趋于高恶性度 .良性病变误诊为乳腺癌 1 5例 ,占 8.7% .结论 近红外光扫描是鉴别良性、恶性病变及诊断乳腺癌的简便、无创、有效的辅助手段 ,并有助于诊断早期乳腺癌 .
AIM To evaluate the significance of the near infrared scan applied in the diagnosis of the breast cancer. METHODS To compare the diagnosis of 172 patients with breast cancer made by near infrared scan before operation with the final pathological diagnosis after operation. RESULTS The overall of near infrared scan was 91.3%. In the cases with breast mass 2~5 cm in diameter, the rate of correct diagnosis of the pre operation scan was 95.4% and 100% with diameter more than 5 cm. The rate dropped to 74.4% with the mass less than 2 cm in diameter. 2 cases of early stage breast cancer with no palpable mass were found by the near infrared scan. 157 cases were verified by pathological sections after operation. Among them, the highest incidence of the breast cancer was at the age between 40~50 (31.2%), followed by the age between 30~40 (28.7%). The malignant degree of the tumor was closely related to the gray shadow and vascular change of the breast mass of near infrared scan. 15 benign cases out of 172 cases were misdiagnosed as malignant and the error rate was 8.7%. CONCLUSION: The computerized near infrared scan is a simple, non trauma and effective method in the differential diagnosis of the breast cancer and is clinically helpful in the early stage diagnosis.
