Selection of breast-preservation therapy for primary invasive breast carcinoma.

Breast-preservation treatment for primary breast cancer should not be used for all women. Women frequently excluded from consideration for such treatment or who choose not to have it may be elderly and not concerned about cosmetic appearance or live at a distance so that 6 weeks of daily trips to radiotherapy would be inconvenient or even impossible. Also, if radiotherapeutic expertise or facilities are not available, a breast-preservation program is difficult. In Massachusetts, a full course of just over 6000 cGy (4500 cGy to the whole breast and a 1600-cGy local boost) costs roughly $6000. Thus, breast preservation is more expensive than mastectomy even with reconstruction, as patients still frequently require a hospital admission with general anesthesia for an axillary dissection. Although insurance policies cover such expenses, patients who do not have insurance or have inadequate coverage may find the extra expense of the breast-preservation technique burdensome or impossible. Women with a small breast and a proportionately large cancer may have an unsatisfactory cosmetic outcome after appropriate lumpectomy. The cosmetic result in such patients frequently cannot be predicted beforehand; this fact adds emphasis to the need for a two-step process of lumpectomy and then re-evaluation of the cosmetic outcome as well as pathologic features for decisions regarding breast preservation. Finally, women may have strikingly different attitudes toward breast preservation than expected by the surgeon. For some women, the urge to preserve the breast is so strong that they will accept virtually any risk to achieve this option, whereas for other women, the constant anxiety about a recurrence or undergoing radiation therapy is traumatic enough that they readily accept mastectomy. In our referral surgical oncology practice, roughly 60% of patients are currently treated with breast-preservation techniques; the remainder undergo mastectomy, with immediate reconstruction in approximately three fourths of the cases. The proportion of patients who elect to have breast preservation depends greatly on local medical customs and attitudes; the radiotherapeutic skills available; women's attitudes, which frequently are dependent on the local press and publicity; and the surgeon's interest and enthusiasm for such a program. There is no appropriate proportion of patients who should be treated by breast-preservation techniques, but clearly, the proportion of patients so treated increases with experience, acceptability, publicity, and availability. Thus, the selection of breast-preserving therapy for individual patients is a result of an extraordinary array of factors that need to be considered in each patient.(ABSTRACT TRUNCATED AT 400 WORDS)
