PURPOSEnTo examine the predictive value of tumor- and treatment-specific prognostic indicators of relapse-free survival (RFS) and overall survival (OS) in patients with high-risk breast cancer (HRBC) treated with high-dose chemotherapy (HDCT) and stem-cell rescue.nnnPATIENTS AND METHODSnBetween June 1989 and September 1994, 114 patients with HRBC (stage II with > or = 10 axillary lymph nodes involved, stage IIIA, and stage IIIB inflammatory carcinoma) received adjuvant chemotherapy followed by HDCT with etoposide, cyclophosphamide, and either doxorubicin (CAVP) or cisplatin (CCVP). Variables analyzed included stage, tumor size, number of axillary nodes involved, grade and receptor status, and types of adjuvant chemotherapy and radiation therapy and HDCT.nnnRESULTSnWith a median follow-up time of 46 months (range, 23 to 93), Kaplan-Meier estimates of 3.5-year OS for stage II, IIIA, and IIIB HRBC are 82% (95% confidence interval [CI], 67% to 97%), 79% (95% CI, 67% to 91%), and 72% (95% CI, 53% to 91%); RFS estimates are 71% (95% CI, 56% to 85%), 57% (95% CI, 43% to 72%), and 50% (95% CI, 29% to 71%) irrespective of the HDCT regimen. In univariate analysis, the risk of relapse was lower for patients with progesterone receptor (PR)-positive tumors (risk ratio [RR], 0.43; 95% CI, 0.22 to 0.81; P = .01) and higher for patients with inflammatory carcinoma (RR, 2.20; 95% CI, 1.02 to 4.76; P = .05). OS was better for patients with PR (RR, 0.16; 95% CI, 0.05 to 0.55; P = .003) and estrogen receptor (ER)-positive tumors (RR, 0.42; 95% CI, 0.17 to 1.02; P = .05); OS was worse for patients with high-grade primary tumors (RR, 4.08; 95% CI, 1.21-13.7; P = .02). In multivariate analysis, PR positivity was associated with improved RFS (P = .01) and OS (P = .001).nnnCONCLUSIONnHDCT in selected patients with HRBC is safe and warrants further evaluation. Patients with receptor-negative, high-grade, or inflammatory tumors require improvement in their therapeutic options. Better assessment of the role of HDCT awaits completion of ongoing randomized trials.

OBJECTIVEnThis study was conducted to examine the histopathologic changes in tamoxifen-treated postmenopausal patients with endometrial thickness > or = 5 mm with transvaginal ultrasonography.nnnSTUDY DESIGNnThirty-five tamoxifen-treated postmenopausal breast cancer patients underwent transvaginal pelvic ultrasonography with endometrial thickness > or = 5 mm followed by either curettage-hysteroscopy (n = 24), or hysterectomy (n = 11). Endometrial histopathologic findings were examined.nnnRESULTSnOverall, endometrial polyps were the most common histopathologic finding (23 of 35 patients). Endometrial cystic atrophy was uncommonly detected in patients undergoing curettage-hysteroscopy (1 of 24 patients) compared with patients undergoing hysterectomy (9 of 11 patients). No cases of endometrial cancer or hyperplasia were detected.nnnCONCLUSIONSnEndometrial polyps were a frequent finding in tamoxifen-treated postmenopausal women who had endometrial thickness > or = 5 mm with the use of transvaginal ultrasonography. Endometrial cystic atrophy may explain thickened endometrium on transvaginal ultrasonography in this patient population with no evidence of endometrial polyps, hyperplasia, or adenocarcinoma after surgical evaluation.

Histopathologic effects of tamoxifen on the uterine epithelium of breast cancer patients: analysis by menopausal status

Kathryn F. McGonigle; Selena A. Lantry; Tamara Odom-Maryon; Akiko Chai; Steven A. Vasilev; Jean F. Simpson

We evaluated the histopathologic changes of the uterine epithelium in 73 breast cancer patients with tamoxifen stratified by menopausal status. Clinicopathologic data at the time of breast cancer diagnosis and endometrial sampling were analyzed and compared with 122 breast cancer patients not receiving the drug. The incidence of endocervical and/or endometrial polyps was increased in tamoxifen-treated postmenopausal patients compared with untreated patients, 43% (25 of 58) and 24% (16 of 68), respectively (odds ratio=2.46, P=0.02). In contrast, there was no increase in polyps in premenopausal tamoxifen-treated patients. This finding suggests that the effects of tamoxifen on the endometrium may vary with menopausal status.

Effects of tamoxifen on the cytology of the uterine cervix in breast cancer patients

Bonnie L. Gill; Jean F. Simpson; George Somlo; Kathryn F. McGonigle; Sharon P. Wilczynski

Tamoxifen, a nonsteroidal antiestrogen, is the endocrine therapy of choice for all stages of breast cancer. Because tamoxifen is well tolerated and has minimal side effects, it is currently being evaluated in large scale trials as a chemopreventive agent for women at risk for developing breast cancer. The potential adverse effects of tamoxifen, specifically the development of proliferative lesions of the endometrium, coupled with the prospect of its wider use, places new emphasis on recognizing tamoxifen‐associated histologic and cytologic changes in the female genital tract.
