Purpose : The purpose of this study is to analyze the usefulness of breast
thermography in assessing the prognosis in breast cancer and to obtain correlative
evidence between thermographic prognosis and prognostic factors for breast cancer.
Materials and Method : Thermographic examinations were performed in a room
maintained at 20¡É. The patient was undressed to the waist, with both arms elevated
for 10 minutes prior to the examination in order to cool and equilibrate the breast skin
at room temperature. Digital infrared thermographic system was used (NEC, San-ei,
Therm Tracer 6T67). The thermographic prognosis was classified according to Dr.
Hobbins (S1=good, S2=fair and S=poor) suggested by Dr. Hobbies. The results were
analyzed by Chi-Squire. One hundred three patients of breast cancer were examined by
digital infrared thermographic system between January 1992 and December 1996.
Results : The mean age was 48, with a range from 20 to 85. According to the TNM
classification 25 (24%) were in stage ¥°, 47 (46%) stage ¥±, 29 (28%) stage ¥², and 2
(2%) stage ¥³. The tumor size ranged from 0.5 to 20 §¯ (mean 4 §¯). On histologic
examination, 43 (43.%) patients had metastasis in the axillary nodes. 40 (55%) patients
was estrogen-receptor positive. The nuclear grade ¥° was 46 (35%) patients, ¥± 24
(28%) and ¥² 16 (19%). The classification of thermographic prognosis were S1 in 47
cases (46%), 52 in 32 (31%) and 53 in 24 (23%). The classification of the thermographic
prognosis was found to be statistically correlated with tumor size (p<0.0001), axillary
node status (p<0.0001) and TNM tumor stage (p<0.0001). But nuclear grade and
estrogen receptor were not statistically correlated with the thermographic prognosis. The
correlation between thermographic prognosis and actual survival rate was not available.
Conclusion : These results suggest that breast thermography would be useful as a
predictor in breast cancer before surgery.
