Conservation therapy for invasive lobular carcinoma of the breast.

Earlier literature suggests a high incidence of multicentricity and bilaterality, with an overall poor prognosis, in patients with invasive lobular carcinoma of the breast. Consequently, there is considerable disagreement regarding appropriate local management of this disease. To determine the influence of invasive lobular histologic findings on local tumor control, disease-free survival, and overall survival, the authors reviewed 60 patients with Stage I and II invasive lobular breast carcinoma treated with local tumor excision and radiation therapy between 1981 and 1987 (mean follow-up, 5.5 years; range, 2.5 to 10 years). The 5-year actuarial risk of locoregional recurrence was 5%, with two of three failures occurring in the regional lymphatics. The mean time to locoregional failure was 28 months. The 5-year actuarial disease-free survival (84%) and overall survival (91%) were comparable to those seen in several large series of similarly treated patients with invasive ductal carcinoma. Contralateral breast cancer occurred at a rate of approximately 0.6% per year. This study and a review of the literature suggest that breast conservation, with local resection and radiation therapy, is appropriate therapy for invasive lobular breast cancer.

Breast conservation management of breast tumors 4 cm or larger.

Randomized studies of stage I and II breast cancer have shown that breast conservation treatment is equivalent to modified radical mastectomy in regard to local-regional control and survival. Little has been published on breast conservation for patients with large tumors. We analyzed 68 patients with tumors measuring 4 cm or larger (range, 4 to 12 cm) treated with breast-conserving surgery and radiation therapy. The median follow-up was 46 months; the mean tumor size was 5 cm. The 5-year actuarial local-regional recurrence rate was 8.5%, and the overall survival and disease-free survival rates were 76% and 68%, respectively. We conclude that breast conservation treatment may be a reasonable alternative to mastectomy in patients with tumors 4 cm or larger without compromise in local-regional control or survival, while achieving acceptable cosmesis.

Reduction mammaplasty following radiation therapy for breast cancer.

This report describes an unusual case in which reduction mammaplasty was performed following radiation therapy for breast cancer. While healing was significantly prolonged (compared with the nonirradiated contralateral breast), the final result was satisfactory from both the functional and the aesthetic standpoint. Women with prior radiation therapy may be considered candidates for reduction mammaplasty. Patients should be warned of the increased risks of wound complications, the likelihood of delayed healing, and the possibility of pigmentation changes in the grafted nipple-areola complex. We elected to transpose the nipple as a full-thickness graft, but consideration also might be given to use of an inferiorly based pedicle flap.

Conservation therapy for breast cancer following augmentation mammaplasty.

Breast conservation therapy (wide local excision, axillary lymph node dissection, and whole-breast irradiation) is an increasingly popular alternative to mastectomy for breast cancer patients. A sizable (and growing) number of breast cancers occur in women with prior augmentation mammaplasty. Augmented breast cancer patients are currently being treated with conservation therapy, but no study has investigated complications and cosmetic results of radiation therapy specifically in this group of women. Between 1981 and 1988, we used conservation therapy in 17 augmented breast cancer patients. Fifteen patients were available for follow-up. In 10 (67 percent), significant capsular contracture occurred in the irradiated breast an average of 12 weeks following completion of treatment. Four patients have undergone revisionary surgery to correct symptoms arising from contracture. This poor outcome contradicts the results reported in previously published studies. We conclude that irradiation of the breast for cancer in augmented women results in a high incidence of scar-tissue contracture and poor cosmetic results.

Vasoseminal vesiculography in staging adenocarcinoma of prostate.

We found vasoseminal vesiculography useful in staging adenocarcinoma of the prostate and in measurement of radiotherapy ports. In 12 patients who had radical prostatectomies, the histologic findings correlated well with the vasoseminal vesiculograms. Criteria for reading benign prostatic hyperplasia and prostatic carcinoma have been well established in the literature and are reviewed.
