Local recurrences and distant metastases are partially independent events that occur at different times; several predicting factors also differ. However, women with local recurrences have increased risk of distant metastases. In particular, women 35 years old or younger at first diagnosis who had initial peritumoral lymphatic invasion and local recurrence within 2 years are at high risk for distant spread. For recurrence in cases with an extensive intraductal component or where initial local surgery was possibly inadequate, women are at lower risk.

Visual and ophthalmologic complaints are common during 4-HPR treatment; their estimated 5-year cumulative incidence is close to 20% and 8%, respectively. However, the pattern of occurrence over time and the underlying mechanisms of these two types of complaints seem different.

For 56 cases of carcinoma of the breast, results of the immunocytochemical assay for estrogen and progesterone receptors performed on preoperative fine-needle aspirates were compared with those obtained on scraping material from the same tumors. The value and usefulness of this last analysis was demonstrated in a previous study. The level of agreement between the two cytological techniques was assessed by the k statistic. A high level of agreement was found, with k values of 0.909 and 0.889 for estrogen and progesterone receptors, respectively. The results reported here revealed the reliability of steroid receptor determination on fine-needle aspiration biopsies, provided that sufficient cellularity was available. This technique can replace the open biopsy procedure, in as much as it represents a rapid, almost painless, and easily repeated method for the assessment of the receptor status, and is useful for treatment decisions at any time during the course of the disease.
