Thermography results of 126 patients were analysed for the diagnosis of recurrences of rectal cancer. Sixteen patients were examined after radical operations for rectal cancer without signs of recurrence to study the features of a thermal regimen in this area. The examination included thermoscopy, thermography and distant thermometry. The presence of the zone of hyperthermia in the perineum with the involvement of the sacral region and the coccygeal bone after extirpation of the rectum was shown to indicate cancer recurrence. The coincidence of thermography findings with those of computerized and ultrasound tomography was observed in 81.7% of the cases. As a result of a perineal fistula, chronic prostatitis, etc., false positive results of thermography were marked in 17 (18.3%) patients. False negative results were not observed. A rise of local temperature from +0.5 to 1 degrees C was considered suspicious of cancer recurrence. These patients were actively followed up and it allowed one to confirm cancer recurrence in them after 3-6 mos. The use of thermography as a screening test made it possible to detect cancer recurrence and to define a high risk group in need of an active follow up and more thorough clinical examination.
对126例患者的热成像结果进行分析，以诊断直肠癌复发情况。对16例直肠癌根治术后无复发迹象的患者进行检查，以研究该区域热调节的特征。检查包括热镜检查、热成像和远距离温度测量。直肠切除术后，会阴区出现高热区并累及骶骨区域和尾骨，提示癌症复发。81.7%的病例中观察到热成像结果与计算机断层扫描和超声断层扫描结果相符。由于会阴瘘、慢性前列腺炎等原因，17例（18.3%）患者出现热成像假阳性结果。未观察到假阴性结果。局部温度升高0.5至1摄氏度被认为可疑癌症复发。对这些患者进行了积极随访，3至6个月后证实其中部分患者出现癌症复发。使用热成像作为筛查试验能够检测癌症复发，并确定需要积极随访和更全面临床检查的高危人群。
