Studies on the Scoring System of Diagnosis Using Thermography for Breast Cancer and its Clinical Application

探讨了热像图在乳腺癌诊断中的作用。应力热成像显示了肿瘤血管对冷却盐水（4 ℃）或血管紧张素II输注的抵抗力。此外，热像表现与淋巴结转移密切相关。肿瘤与对侧温差大于1.5 ℃者预后差。根据病理检查，热像图反映了癌细胞的扩散，虽然热像图的诊断方式不能与乳腺X线摄影或超声相比，但接触式热像图（sinotest）在乳腺癌诊断中的作用与远红外热像图相当。乳腺癌中约有40%左右的乳腺组织出现与对侧温差大于1^0 ℃的高热区，而良性病变中未见，提示乳腺组织的热像表现反映了乳腺组织的代谢和血管现象，不仅可作为乳腺癌的诊断指标，而且可作为乳腺癌普查中高危人群的发现。

The usefulness of thermography in the diagnosis of breast cancer patients was investigated. Stress thermography revealed the resistance of tumor vessels against the infusion of cooled saline (4^0C) or angiotensin-II. Furthermore, thermographical findings closely correlated with lymphnode metastasis. Poor prognosis was found in patients with temperature difference of more 1.5^0C between tumor and contralateral region. According to pathological examination, the hyperthermia area reflected the spread of cancer cells.Although the diagnositic modality of thermography could not compared with that of mammography or ultrasonography, the usefulness of contact thermography (sinotest) in diagnosis of breast cancer was comparable to the tele thermography. Hyperthermic areas with temperature difference of more than 1^0C against contralateral region were found in approximately 40% of nonpalpable breast cancer, while not in benign lesions.These results indicated that thermographic appearance reflect the metabolic and vascular phenomenon in breast tissue and might be useful for not only a prognositic indicator but the detection of high risk group in mass screening.
