Abstract

Mammogram is a common diagnostic modality for breast carcinoma. Diagnostic mammogram
is available at only few centers in Nepal. The aim of this study was to determine the accuracy of
diagnostic mammogram in Nepalese women suffering from breast carcinoma. A retrospective
analysisofthebreast carcinomawas carriedoutintheDepartmentof Surgery,TribhuwanUniversity
Teaching Hospital from October 1995 to October 2007. Out of 556 patients with histologically proven
breast carcinoma, 378 patients (68%) had undergone mammography. Breast carcinoma was identified
on mammography in 328 (87%) cases while 50 cases (13%) were reported as normal or benign
lesions. Diagnostic mammogram had a sensitivity of 86.8%, a specificity of 98.6% with a positive
predictive value of 68.8% and a negative predictive value of 99.5%. In mammographically missed
breast carcinoma, 34% were less than 40 years of age (P<0.05), 60% were premenopausal (P<0.05)
and 88% patients presented with a painless lump. The study shows that the diagnostic accuracy of
the mammogram is very high. However, there is a chance of missing the breast carcinoma in young
and premenopausal women.
Key words: breast carcinoma, diagnostic mammogram, premenopausal women
