2 PATIENT CARE EVALUATION STUDY DISPARITIES IN THE MANAGEMENT OF ELDERLY BREAST CANCER PATIENTS Cynthia Osborne, MD, Mabel Mardones, MD, Janet Reynolds, CTR, Andrew Lupo, MS-IV Breast cancer is the most widespread cause of cancer among women in the United States. 1,2 In 2015, estimates of 231,840 new cases of invasive breast cancer will be diagnosed in women in the U.S., as well as an added 60,290 cases of in situ breast cancer. 1 Along with this high incidence of breast cancer, there is a high rate of death from breast cancer. In the U.S., estimates of 40,290 women will die from breast cancer in 2015, making it the second leading cause of death in women from cancer. 1 Worldwide, breast cancer was the leading cause of death in women in Breast cancer is a disease of aging. In the U.S., the median age of diagnosis of breast cancer is 61 but peaks in the 70s and then declines. The U.S. population is aging; from 2003 to 2013, the population of people aged 60, and above increased from 48.1 million to 62.8 million people, a rise of over 30%. 3 These numbers are expected to more than double by 2060 to 98 million people aged 60 or older. Analysis of the current data shows that older women are more numerous, with 25.1 million women to 19.6 million men, with a sex ratio of women for every 100 men. 3 By age 85 and over, this ratio increases to women for every 100 men. 3 As a result, women age 80 years and older are one of the fastest-growing segments of the U.S. population. s of death from breast cancer continue to increase as women age, leading to the statistic that 57% of all breast cancer deaths occur in women in the 65 years of age and older group. 1 Even with this high rate of death from breast cancer in older women, little is known about the characteristics of their cancer, treatment choices, or survival among this cohort. Some of this lack of data is due to the fact that historically few randomized controlled trials evaluating breast cancer treatments included women age 70 years or older, and most observational studies are limited by small sample size. In addition, increasing age is often accompanied by increasing comorbidity with associated reduction in physical conditioning, organ reserve, and cognitive and social functioning. Therefore, this leads to an inherent uncertainty as to the optimal approach in treating elderly women with breast cancer. This may negatively impact treatment options. Both observational studies and a randomized clinical trial, the TEAM trial which did not exclude women from participation based on age, have demonstrated several trends in older women with breast cancer. At presentation the tumor stage is higher, lower rates of breast conserving surgery with radiation are performed, and lower rates of

3 surgery and chemotherapy are administered as compared to younger breast cancer patients. 4 Additionally, while older women have been observed to die more frequently from all other causes, the risk of dying from breast cancer increases significantly with age. In order to better address the conundrums in treating this rapidly growing population of older women with breast cancer, we are evaluating patterns of care of elderly breast cancer populations as compared to younger patients treated in the Baylor Health Care System facilities from METHODS Using Baylor Health Care System Cancer Registry data, we identified all breast cancer cases seen throughout the system from Accessing the Texas Oncology iknowmed EMR, we then determined the type of surgery used in the general population by age. Other treatment trends that were included were frequency of breast conserving surgery with adjuvant radiation (BCS with XRT), radiation for patients with four or more positive lymph nodes, receipt of chemotherapy for hormone negative breast cancers, and receipt of hormone therapy for hormone positive breast cancers. Additionally, we evaluated the type of surgery performed in the early stage (I-II) breast cancer patients by age. Briefly, we followed the 2013 NCCN guidelines. 5 They are as follows: women who underwent a total mastectomy or lumpectomy and surgical axillary staging with four or more positive nodes are to have radiation therapy. Women with hormone receptor positive disease should have adjuvant endocrine therapy, while those with HER2 positive disease should receive adjuvant therapy with trastuzumab. Lastly, women with hormone receptor negative and HER2 negative disease should be treated with chemotherapy. Finally, one important point is that these guidelines do not take age into account. Thus, there are no specific guidelines for older women with breast cancer. RESULTS Breast Cancer Surgery We encountered a total of 4,933 surgeries of which 2,943 (59.7%) were mastectomies and 1,990 (40.3%) were breast conserving surgeries. In those patients 80 years of age and above, patients were split almost evenly between mastectomies (49.6%) and breast conserving surgery (50.4%). These rates were similar to those for women from 65 to 79 years of age (49.9% mastectomy and 50.0% for BCS). However, a greater percentage of women under the age of 65 had mastectomies (64.2%) compared to breast conserving surgery (35.8%). When the patients with early stage disease (stage I-II) were grouped by type of surgery and age, it was noted that women under 60 had more mastectomies; however, after the age of 60, this trend was reversed. Radiation therapy post Breast Conserving Surgery (BCS) When looking at the trends in radiation post BCS, we noted a steady decrease in the percentages of radiation-treated patients, particularly in those over the age of 80. Only 66% of patients received XRT in the 80 and over group, in comparison to 81 to 91% in those women under 40 years of age to 69. About 79% of patients from age 70 to 79 received radiotherapy, still greater than women 80 years of age and above. In those patients over the age of 80, 11% were not offered XRT and about 10% of patients in this category refused the therapy. Radiation treatment in women with four or more positive lymph nodes The trends in radiotherapy given to patients with breast cancer with four or more positive lymph nodes were consistently above 50% across all groups. There was, however, quite a bit of variability in the numbers. Levels of radiotherapy for four or more positive lymph nodes declined from a high of 77% for women under 40 to a low of 58% for women 60 to 69 years of age, while for patients from 70 to 79 years of age, this number spiked to 81%. Levels then dropped to 65% and 50% for women in the 80 to 89 and 90 and over group, respectively. Interestingly, at the same time these changes were seen in women treated with radiotherapy, the number of cases where radiotherapy was not recommended increased from 17% for women under 40 years of age up to 31% for women 60 to 69 years of age. Then this percentage of women who were not recommended therapy dropped to 2% in women 70 to 79 years of age. Therefore, this spike of 81% of women treated in the 70- to 79-yearold group may represent the fact that more women were recommended to undergo radiation treatment compared to the younger age groups.

4 The drop in radiation treatment in women over 80 may be due to the fact that a greater percentage of these patients refused treatment compared to any other age group. Chemotherapy for women with hormone negative breast cancers We noted a high incidence of chemotherapy given to all patients with hormone negative breast cancer who were less than 70 years of age. Above this threshold, there was a steep decline in patients treated with chemotherapy, with only 32% of women above the age of 80 being treated. In this group of older patients, a greater number of patients were not recommended or were contraindicated for chemotherapy treatment. This contraindication may be a result of patient comorbidities, such that physicians may have been concerned about treatment side effects. Endocrine therapy for hormone positive breast cancers There were a consistently high percentage of patients being offered hormone therapy across all age groups for women with hormone positive breast cancers. However, compared to women under 70 years of age, there still was a slight decrease in those women above the age of 70 and 80 (73% vs 74%), respectively, compared to younger women (79% to 84%). When the combination of endocrine therapy and radiotherapy was investigated by age, the results were mixed. In patients under 40 to 49 years of age, the percentage of patients who received hormone therapy with radiotherapy versus without radiotherapy was about 50/50. Beginning at age 50 to 59 years of age, there was a divergence, with more patients on hormone therapy getting radiotherapy versus those who did not receive radiotherapy. This difference was greatest for patients from 80 to 89 years of age (65.4% versus 34.7%, respectively). DISCUSSION In 2006, there were several studies that used the Surveillance, Epidemiology and End Results (SEER)-Medicare data set and examined the effectiveness of radiotherapy and chemotherapy among older women with breast cancer Results from numerous studies support the notion that older women are not treated according to the NCCN guidelines for breast cancer; however, the impact this has on breast cancer specific survival is controversial. 11 One study demonstrated the efficacy of surgery on survival of a small number of older breast cancer patients. 12 In a follow-up study using 369 patients aged 80 years or more, standard mastectomy was associated with a better breast cancer specific survival. 13 The complications after surgery for older breast cancer patients primarily involve slower wound healing, wound infection, and seromas. 14 In a study of older women with hormone receptor positive breast cancer, they found that patients could be divided into one of three groups; either patient declined, where the patient ruled out surgery, patient considered where the patient considered surgery but decided to undergo endocrine therapy instead, or surgeon declined where the surgeon decided the patient comorbidities were incompatible with surgery. 15 Thus, this group of patients is extremely diverse and both patients and surgeons may be more hesitant to decide that surgery is a viable option. In looking at our patients, about the same number underwent BCS versus mastectomy from age 70 on. This may be a selected group, as we did not include patients who did not have surgery, but our numbers are still high. We had 254 patients from 80 to 89 years of age who either had BCS or mastectomy. In our analysis, we note that women over 80 with breast cancer received less XRT post BCS, and for known indications, lower rates of systemic chemotherapy were being offered compared to their younger counterparts. We should note that in the 80 and older group there were higher contraindications for chemotherapy than in the younger breast cancer patients, indicating there may be more comorbidities present in these patients. These findings seem

5 to be in agreement with previously published trials. 7,11,16,17 Based on the results of our initial survey of patients treated at BHCS, we intend to compare women with early stage breast cancer outcomes into two groups; older and younger (>80 years of age and years of age). We will examine the impact of age on breast-related and other causes of death. Analysis will be performed within stage, adjusted for tumor characteristics, treatments received, and comorbidities.
