    Notizen: Abstract Background: To evaluate the purported decreased survival of pregnancy-associated (PA) breast cancer, a previously described homogeneous cohort of women of childbearing age with primary operable cancer was studied. The current analysis was designed to (a) identify those patients among the cohort known to have PA cancer and (b) compare clinical factors, pathologic characteristics, stage at diagnosis, and survival statistics for PA and non-PA cancer subgroups. Methods: All patients ⩽30 years of age who underwent definitive operation between 1950 and 1989 at the Memorial Sloan-Kettering Cancer Center (MSKCC) for primary operable (stages 0-IIIA) breast adenocarcinoma were analyzed. Results:|Twenty-two of the 227 young women with primary operable breast cancer had PA cancer. Disease-related survival was decreased (p=0.004) in these 22 women compared with the remaining 205 patients with non-PA cancer. PA cancer patients were found to have larger tumors (p〈0.005), and a greater proportion had advanced staged (IIB or IIIA) cancers (p〈0.02). Among patients diagnosed with early invasive cancers (stages I or IIA), no difference (p=NS) in survival was observed comparing PA and non-PA subgroups (73% vs. 74% 10-year survival). Patients with stage IIIA cancer had shorter disease-free and overall survival when associated with pregnancy (0% vs. 35% 10-year survival). Conclusions: Women 30 years of age or younger with PA breast cancer have decreased survival compared with patients with non-PA cancer from the same cohort. Women with PA cancer have larger, more advanced cancers at the time of definitive surgery. Women with early staged PA cancers appear to have survival similar to that for women with early staged non-PA cancer.

    Notizen: Abstract Background: Management of patients with breast cancers ≤1 cm remains controversial. Reports of infrequent nodal metastases in tumors ≤5 mm has led to suggestions that axillary dissection should be selective, and that tumor characteristics should guide adjuvant therapy. Methods: A retrospective review of 290 patients with breast cancer 1 cm in size or smaller from 1989 to 1991 was done. Distant disease-free survival (DDFS) was the primary outcome measure. Results: There were 95 T1a (≤5 mm) and 196 T1b (6–10 mm) cancers. Nodal metastases were found in 8 T1a and 26 T1b tumors. Larger size, poorer differentiation, and lymphovascular invasion (LVI) were associated with more nodal metastases, but none of these trends reached statistical significance. The 6-year DDFS was 93% for node-negative and 87% for node-positive patients (P = .02). Overall, breast cancers with poorer differentiation and LVI trended toward a poorer outcome. For patients with node-negative tumors, LVI was associated with a poorer outcome (P = .03). The size of the primary tumor was not predictive of outcome. There were no nodal metastases or recurrences in the 18 patients with microinvasive breast cancer. Conclusions: Lymph node status is the major determinant of outcome in breast cancers 1 cm in size or smaller. Accurate axillary assessment remains crucial in management of small breast cancer.

    Notizen: Abstract Background: Young age has been hypothesized to be an adverse prognostic factor for women with breast cancer. This association, based on historical data, may not reflect recent advances in breast cancer management. Methods: A retrospective study was conducted of all women age 30 or younger who underwent definitive operation at our institution for primary operable breast carcinoma during one of two consecutive 20-year periods (1950–1969 or 1970–1989). All cancers were restaged according to current staging criteria. Actuarial survival and recurrence-free survival rates from the two patient eras were compared with each other and with published statistics for older breast cancer patients. Results: Eligibility criteria were met by 81 women from the 1950–1969 era and 146 women from the 1970–1989 era. Histologic diagnoses, tumor sizes, incidence of axillary nodal metastases, number of positive nodes, and American Joint Committee on Cancer stage at presentation were similarly distributed in the two eras. Despite these similarities, improved survival (p=0.009) was observed in the later era. Local recurrences were also more common (p〈0.05) in the later era in association with less extensive resections. These local recurrences had an adverse impact on recurrence-free survival in the later era, but no concomitant decrease in overall survival was observed. Node-positive patients who received chemotherapy demonstrated a trend toward improved survival (p=0.06) compared with node-positive patients who did not. Survival for patients in the later era was similar to that for older women as reported in other published series. Conclusions: The stage of presentation of breast cancer in women 30 years or younger appears unchanged from prior decades, but survival has improved in association with the use of less extensive surgical resections and the introduction of cytotoxic chemotherapy. With current treatment, primary operable breast cancer in young women appears to have a similar prognosis to breast cancer in older women.

    Notizen: Abstract Background: Primary prevention strategies such as chemopreventive agents (e.g., tamoxifen) and bilateral prophylactic mastectomy (PM) have received increasingly more attention as management options for women at high risk of developing breast cancer. Methods: A total of 370 women, who had registered in the Memorial Sloan-Kettering Cancer Center National Prophylactic Mastectomy Registry, reported having undergone a bilateral PM. Twenty-one of these women expressed regrets about their decision to have a PM. A psychiatrist and psychologist interviewed 19 of the women about their experiences with the PM. Results: A physician-initiated rather than patient-initiated discussion about the PM represented the most common factor in these women. Psychological distress and the unavailability of psychological and rehabilitative support throughout the process were the most commonly reported regrets. Additional regrets about the PM related to cosmesis, perceived difficulty of detecting breast cancer in the remaining breast tissue, surgical complications, residual pain, lack of education about the procedure, concerns about consequent body image, and sexual dysfunction. Conclusions: Although a PM statistically reduces the chances of a woman developing breast cancer, the possibility of significant physical and psychological sequelae remains. Careful evaluation, education, and support both before and after the procedure will potentially reduce the level of distress and dissatisfaction in these women. We discuss recommendations for the appropriate surgical and psychiatric evaluation of women who are considering a PM as risk-reducing surgery.

    Notizen: Abstract Background: We investigated the incidence of axillary lymph node metastases in patients with T1a (⩽0.5 cm) and T1b (〉0.5 cm and ⩽1.0 cm) breast cancers. Methods: The charts of 2000 patients who underwent axillary lymph node dissection for breast cancer at our institution from 1989 to 1991 were reviewed. Of these, 81 patients had T1a and 166 had T1b primary breast cancers. Results: Among the 247 patients with T1a and T1b breast cancers, nodal metastases were present in 30 (12.1%), with a 7.4% positivity rate for patients with T1a and 14.5% positivity rate for T1b tumors. Of the 212 patients who had ⩾10 nodes dissected, 29 (13.7%) had positive nodes. Of those, 6 of 60 (10.0%) patients with T1a and 23 of 152 (15.1%) with T1b tumors had positive nodes. The presence of lymphovascular invasion (LVI) predicted a significantly higher nodal positivity rate (27.8% vs. 10.9%,p=0.05). Conclusions: Of patients with adequately evaluated axillae, 10% with T1a and 15% with T1b cancers were found to have nodal metastases. Although LVI was significantly associated with a higher risk of lymph node metastases, we could not characterize any subgroup at acceptably low risk of nodal positivity. Until a more useful prognostic indicator is discovered, axillary dissection should continue to be part of the mainstay of management for small breast cancers.

    Notizen: Abstract Background: The discovery of a cadre of breast cancer susceptibility genes has resulted in an increase in the number of women seeking information about prophylactic breast surgery, but virtually no large-scale prospective databases exist to assist women considering prophylactic mastectomy. Methods: The authors constructed a National Prophylactic Mastectomy Registry comprised of a volunteer population of 817 women from 43 states who have undergone prophylactic mastectomy. Results: In the registry, 370 women had undergone bilateral prophylactic mastectomy. Twenty-one (5%) women expressed regrets about the procedure. The median follow-up was 14.6 years (mean 14.8 years; range 0.2–51 years). Those with regrets were subsetted into those with major (n=10) or minor (n=7) regrets. Regrets were more common in those women with whom discussion about prophylactic mastectomy was initiated by a physician (19/255), compared with patients who initiated the discussion themselves (2/108;P〈.05). Conclusions: The overall satisfaction rate of 95% reported here may be explained by the voluntary nature of this registry. The most important factor that predicts an unfavorable outcome following bilateral prophylactic mastectomy is a physician-initiated discussion.
