ABSTRACT
BACKGROUND:
Major efforts are being directed at the early diagnosis of breast cancer. The diagnosis rate of non-palpable tumors is steadily growing as a result of increased screening by mammography. In most patients with non-palpable lesions, percutaneous image-guided biopsies have replaced wire localization with surgical excision for obtaining tissue diagnosis. In recent years the Israel Ministry of Health initiated a mammograpy screening program. Percutaneous image-guided biopsies have also become widely available.OBJECTIVE:
To assess the impact of these changes on breast cancer surgical treatment in our hospital.METHODS:
The charts of 483 patients operated on in our department for primary breast carcinoma during the years 1997 to mid-2001 were reviewed. Data on the mode of diagnosis, tumor stage, resection margins, and number and types of operations were recorded and analyzed. The term non-palpable tumors relates to tumors necessitating wire localization for surgical excision.RESULTS:
The percentage of patients diagnosed with non-palpable tumors rose from 16.2% in 1997 to 47.4% in 2001, with an average size of 2.6 cm for palpable and 1.7 cm for non-palpable tumors. The rate of preoperative diagnosis for non-palpable tumors rose from 6.2% in 1997 to 96.4% in 2001. The rate of involved or very close margins was reduced by 73% in the patient group diagnosed preoperatively as compared to those without a preoperative diagnosis (10.6% vs. 39.4%). Finally, the percentage of patients who had two operations fell from 56.2% in 1997 to 11.1% in 2001.CONCLUSIONS:
The mammography screening program in Jerusalem in 1997-2001 was effective in increasing the relative percentage of non-palpable breast cancers with reduced tumor size at diagnosis. The improved availability of preoperative tissue diagnosis in these patients reduced the number of surgical procedures needed.
