676 Background: We have previously reported that clodronate prevents bone loss in breast cancer patients (JCO 1997;15:1341, BJC 1997;75(4):602 and EJC 2001;37:2373). Here we report the 10-year follow-up data. Methods: 268 pre- (PRE) and postmenopausal (POST) node positive breast cancer patients were randomized to clodronate (CL), orally 1.6 g daily, or control groups for 3 years. PRE were treated with adjuvant chemotherapy and POST with antiestrogens (AE), tamoxifen 20 mg or toremifene 60 mg, for 3 years. The BMD of the lumbar vertebrae L1–4 (BMDLS) and femoral neck (BMDFN) was measured before the treatment and at 1, 2, 3, 5 and 10 years. 93 patients were eligible for 10-year analyses: 53 PRE and 40 POST. 132 patients had metastatic disease or died and 39 were either lost to follow-up or had to be excluded because having diseases or medications that influences bone metabolism. Results: PRE: BMDLS decreased -12.4% in the control and −8.7% in the CL group in 10 years: from 0 to 3 years −6.9 % vs. −4.2% and from 3 to 10 years −5.5% and −4.5%, respectively. BMDFN decreased −8.8% and −7.2%: from 0 to 3 years −2.9% vs. −2.6% and from 3 to 10 years −5.9% vs. −4.6%, respectively. POST: BMDLS decreased −3.0% in the AE and −1.7% in the AE+CL group in 10 years: from 0 to 3 years −1.5% vs. + 1.2% and from 3 to 10 years −1.5% vs. −2.9%, respectively. BMDFN decreased −7.7% and −6.0%: from 0 to 3 years −0.1% vs. +1.9% and from 3 to 10 years −7.6% vs. −7.9%, respectively. These differences do not reach statistical significance. At 10-years 18 patients had osteoporosis in LS and 15 in FN. Only 4 patients who had osteoporosis at 10 years had normal BMD before the therapy. Conclusions: As reported previously, clodronate prevents the bone loss during treatment in pre- and postmenopausal women. This beneficial effect seems to be maintained at least for 7 years after treatment termination in premenopausal. In postmenopausal women the effect seems to diminish within time. Due to small numbers of patients these differences are no longer statistically significant. Patients at risk of developing osteoporosis are among those who has pretreatment osteopenia i.e. baseline BMD measurement has predictive value. No significant financial relationships to disclose.

Bone Mineral Density Testing

Purpose: In postmenopausal women with breast cancer treated with aromatase inhibitors (AIs), most expert panels advise baseline bone mineral density testing with a dual-energy x-ray absorptiometry (DXA) scan repeated every 1 to 2 years. How often this recommendation is followed is unclear. Methods: We performed a retrospective analysis of women with stage I to III breast cancer who started AI therapy from January 1, 2008, to December 31, 2010, with follow-up through December 31, 2012, by using the SEER-Medicare database. Selection criteria included AI use for ≥ 6 months and no recent osteoporosis diagnosis or bisphosphonate use. We used multivariable logistic regression to investigate associations between patient characteristics and receipt of a baseline DXA scan. In patients who continued AI treatment, we assessed rates of follow-up scans. Results: In the sample of 2,409 patients (median age, 74 years), 51.0% received a baseline DXA scan. Demographic characteristics associated with the absence of a baseline DXA scan were older age (85 to 94 years v 67 to 69 years; odds ratio [OR], 0.62; 95% CI, 0.42 to 0.92) and black v white race (OR, 0.68; 95% CI, 0.47 to 0.97). Among patients who underwent a baseline DXA scan and continued AI for 3 years, 28.0% had a repeat DXA scan within 2 years and 65.9% within 3 years. In aggregate, of the 1,164 patients who continued with AI treatment for 3 years, only 34.5% had both a baseline and at least one DXA scan during the 3-year follow-up period. Conclusion: The majority of older Medicare beneficiaries with breast cancer treated with AIs do not undergo appropriate bone mineral density evaluation.

PURPOSE: To determine the risk of second malignancies after lumpectomy and radiation therapy (LRT), and to compare it with that in a similar cohort of early-stage breast cancer patients undergoing mastectomy without radiation (MAST). PATIENTS AND METHODS: Between January 1970 and December 1990, 1,029 breast cancer patients at our institution underwent LRT. A cohort of 1,387 breast cancer patients who underwent surgical treatment by mastectomy (MAST), and who did not receive postoperative radiation during the same time period, served as a comparison group. Second malignancies were categorized as contralateral breast versus nonbreast. In the cohort of patients undergoing LRT, a detailed analysis was carried out with respect to age, disease stage, smoking history, radiation therapy technique, dose, the use of chemotherapy or hormone therapy, and other clinical and/or pathologic characteristics. RESULTS: As of March 1999, the median follow-up was 14.6 years for the LRT group and 16 years for the MAST group. The 15-year risk of any second malignancy was nearly identical for both cohorts (17.5% v 19%, respectively). The second breast malignancy rate at 15 years was 10% for both the MAST and LRT groups. The 15-year risk of a second nonbreast malignancy was 11% for the LRT and 10% for the MAST group. In the subset of patients 45 years of age or younger at the time of treatment, the second breast and nonbreast malignancy rates at 15 years were 10% and 5% for patients undergoing LRT versus 7% and 4% for patients undergoing mastectomy (P, not statistically significant). In the detailed analysis of LRT patients, second lung malignancies were associated with a history of tobacco use. There were fewer contralateral breast tumors in patients undergoing adjuvant hormone therapy, although this did not reach statistical significance. The adjuvant use of chemotherapy did not significantly affect the risk of second malignancies. CONCLUSION: There seems to be no increased risk of second malignancies in patients undergoing LRT using modern techniques, compared with MAST. Continued monitoring of these patient cohorts will be required in order to document that these findings are maintained with even longer follow-up periods. With nearly 15 years median follow-up periods, however, these data should be reassuring to women who are considering LRT as a treatment option.

611 Background: It is estimated that approximately 10% of all breast cancer patients will develop local recurrence (LR) at 10 years. Routine surveillance for detection of early breast cancer recurrence is widely performed despite lack of conclusive evidence for an improvement in patient quality of life or potential for cure. A number of historical studies evaluating the effectiveness of routine screening for LR following treatment for early-stage breast cancer have suggested that the diagnosis of LR is more frequent during a routine visit and occurring in asymptomatic patients. However, differentiating the method of detection is not often elucidated. In this study we evaluated the manner in which patients presented with an isolated LR in clinical practice. Methods: Our routine patient follow-up consists of physical exam and mammogram every 6 mos for the first 2 years following breast conserving surgery (BCS) and yearly thereafter. We queried our prospectively collected breast cancer database (1632 patients from July 1986 - July 2004) for patients with an isolated LR following BCS (n=59 (3.6%); two patients had bilateral LRs). Medical records were not available for three patients. Results: At a median follow-up of 45 mos (range: 5–122 mos) there were 58 evaluable LRs: 15 DCIS, 31 infiltrating ductal carcinoma (IDC), 6 infiltrating lobular (ILC), 2 mixed IDC/ILC, 3 invasive cancers NOS and 1 unknown. Patient presentation was as follows: 25 were diagnosed by self-exam, 28 on screening mammogram, 2 were diagnosed by physician (includes one referral), and 3 unknown. Mammogram detected recurrences were more frequent among patients with DCIS whereas self-detected recurrences were more common in patients with IDC (79% vs 33% and 21% vs 67%, respectively; P<0.2). Mean tumor size was larger in self-presentation (2.1 cm; range: 0.8–4.5 cm) than in mammogram detected group (1.6 cm; range 0.4–6 cm). Conclusions: These findings demonstrate the value of mammography as compared to patient detected LRs. Whether a survival advantage exists remains uncertain. Nevertheless routine physician examination in this setting is highly insensitive and its further utility must be considered when devising cost-effective strategies for surveillance of breast cancer patients. No significant financial relationships to disclose.

Increased Risk

93 Background: Women with early-stage TN breast cancers are at increased risk for recurrence (RR) compared to other molecular subtypes, and are often treated with mastectomy without local adjuvant therapy. We wish to evaluate the RR for these women. Methods: In this single institution retrospective study, women with T1-2N0 TN breast cancer who underwent mastectomy between 2008-12 were identified from tumor registry. Adjuvant chemotherapy was allowed, but adjuvant radiotherapy (RT) was excluded. Of 3,000 cases reviewed, 52 women were identified. Median age was 58.5 (30–90). Lesions were high-grade (83%), and T1-2 (47%, 53%). 21 women (42%) had at least 1 risk factor. 5 women were BRCA+. Women underwent total mastectomy or modified radical mastectomy, and the majority (84%) had adjuvant chemotherapy. Results: At a median follow-up of 3.5 years (6-71 months), there were 8 recurrences (15.4%). 3 (5.8% of cohort) were locoregional (LR) only (2 chest wall (CW) and 1 ipsilateral axilla), 6 (11.5%) involved a concurrent LR and distant recurrence, and 2 (3.8%) were distant only. Median time to recurrence was 17.3 months. The isolated LR recurrences (LRR) were at 14, 15.6 and 15.1 months. Most women (41, 78.8%) were alive with NED. 3 were alive with disease, underdoing treatment, and 1 woman was disease free after treatment for CW recurrence. 8 patients (15.4%) are deceased, half from their cancer. On univariate analysis, there was no significant correlation (p>0.05) between age or high-risk features and RR (STATA v 11). Conclusions: T1-2N0 breast cancer patients are believed to have a low RR following mastectomy. TN disease, however, is more aggressive, and the question of irradiating early stage disease after mastectomy has arisen. A single institution, retrospective study found women with T1-2N0 TN disease fare better with BCT that includes RT, compared to mastectomy alone. Other studies have shown no statistical difference in RR between these 2 groups. We found an isolated LRR rate at 3.5 years of 5.8%. Follow-up and ultimately prospective data is needed to determine whether the isolated LRR warrants a change in treatment recommendations for this pt subset.

72 Background: Multiple cancer organizations advocate for the use of treatment summaries and survivorship care plans (TSSCPs) in cancer patients. To better quantify the benefits of a nurse-navigated, culturally and linguistically responsive TSSCP in underserved breast cancer patients, we compared rates of compliance with treatment and follow up in 26 patients who were treated with TSSCPs to 38 similar controls who were treated without TSSCPs. Methods: We prospectively enrolled 26 consecutive, newly-diagnosed breast cancer patients who were given nurse-navigated TSSCPs under an IRB-approved protocol. At their first clinic visit, a trained nurse educated and assisted the patient in the use and completion of the TSSCP. Nurse-navigated TSSCPs were completed at each subsequent visit through 12 months of surveillance. Rates of compliance with treatment and follow up guidelines were compared to 38 similar control patients using a two group Fisher’s exact chi-square test. Statistical significance was set at p-value < 0.05. Results: All patients were treated under Medicaid insurance and 47% were racial and/or ethnic minorities. Time from diagnosis to treatment and time from initial clinic visit to treatment were similar across groups. The rate of compliance with first treatment recommendations was 96% (25/26) in the TSSCP group compared to 79% (30/38) in the non-TSSCP group (p = 0.07). The number of patients compliant with all follow up visits was similar: 22/25 (88%) of TSSCP patients and 22/30 (73%) in non-TSSCP patients (p = 0.31). Of the recommended total follow up appointments, 6/67 in the TSSCP group and 25/120 in the no TSSCP group were “no shows” (p = 0.04). Conclusions: Although the use of nurse-navigated TSSCPs may not improve time to treatment in medically underserved patients, adherence to first treatment recommendations and follow up appointment attendance shows some improvement in patients who participate in nurse-navigated TSSCPs. Further study is needed to fully assess the role of nurse-navigated TSSCPs in improving treatment and surveillance compliance rates and how these rates impact clinical outcomes.

Premenopausal Breast Cancer

PURPOSE In the majority of premenopausal breast cancer patients, an adjuvant chemotherapy-induced early menopause occurs, which is known to be a strong predictor of osteoporosis. We present data on the effect of adjuvant cyclophosphamide, methotrexate, and fluorouracil (CMF) therapy on bone mineral density (BMD) and the efficacy of clodronate on the prevention of bone loss in 148 premenopausal breast cancer patients without skeletal metastases. MATERIALS AND METHODS Patients were randomized to receive oral clodronate 1,600 mg/d or to a control group. In addition, patients were treated with six cycles of CMF therapy. BMD of the lumbar spine and femoral neck was measured by dual-energy x-ray absorptiometry (DEXA) before therapy and at 1 and 2 years. RESULTS Changes in the BMD of lumbar spine and femoral neck were -5.9% and -2.0% without clodronate and -2.2% and +0.9% with clodronate at 2 years (P = .0005 and .017, respectively). Patients who developed amenorrhea after chemotherapy had a rapid bone loss, which was significantly reduced by clodronate. In controls, bone loss was 9.5% in the lumbar spine and 4.6% in the femoral neck, while in the clodronate group, bone loss was 5.9% and 0.4%, respectively, at 2 years. Patients with preserved menstruation had only marginal changes in BMD. CONCLUSION Chemotherapy-induced ovarian failure causes rapid bone loss in premenopausal breast cancer patients. Women older than 40 years are at particularly high risk. Clodronate significantly reduces this bone loss.

Secondary Outcomes

6003 Background: Breast cancer patients usually receive follow-up in specialist cancer clinics. We have reported that family physician follow-up of breast cancer patients is a safe and acceptable alternative to specialist follow-up as measured by the primary clinical outcome of the rate of serious clinical events (Grunfeld et al, JCO 2006;24(6)). We report here the secondary outcomes of this trial: quality of life domains, patient satisfaction and patients’ costs. Methods: Women with early stage breast cancer who had completed adjuvant therapy (patients may have continued on adjuvant hormonal therapy), who were disease free and between 9 and 15 months after diagnosis, were allocated to receive follow-up in a cancer clinic according to usual practice (CC arm) or follow-up from their own family physician (FP arm). For patients without recurrence, quality of life (QL) measured by the SF36, patient satisfaction, and patients’ costs were measured every 6 months. For patients with recurrence QL measured by the EORTC QLQ C-30 was measured at the time of recurrence. Results: 483 patients were allocated to the FP arm and 485 to the CC arm. Median follow-up was 3.5 years. There were no significant differences between groups on change scores for SF36 subscales to 24 months, or EORTC functional subscale scores at the time of recurrence. Patients’ costs of follow-up (travel costs, out-of-pocket expenses, and lost earnings) were significantly less to 24 months (p < 0.02) in the FP arm. Although costs were less between 36 and 48 months, these were not significant. Conclusions: Family physician follow-up of breast cancer patients does not have a negative impact on clinical or QL outcomes and is less costly for patients.
