电脑近红外光扫描对乳腺癌诊断的评价

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１７２例患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２－５ｃｍ及〉５ｃｍ，其诊断正确率为９５．４％和１００％；〈２ｃｍ，则为７４．４％；并检出２例临床无明显包块的早期也腺癌。

Evaluation of computerized near-infrared scan in the diagnosis of breast cancer

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.
