Background: Telemedicine is a useful tool that connects patients to their care team remotely and improves access to medical care for rural residents. This study aimed to determine the telemedicine experience of both rural patients with cancer and their physicians, and to explore factors associated with a positive patient experience. Methods: In this cross-sectional study, cancer patients and physicians in Saskatchewan completed a paper-based survey composed of 32 items or an electronic survey of 18 items, respectively. Logistic regression analysis was performed to assess patient satisfaction in relation to various sociodemographic and cancer-related factors. Results: Overall, 25 physicians and 165 patients participated in the study. Among the physicians, 94% were confident in their telemedicine assessment, 58% agreed that telemedicine improved clinical efficiency, and 73% agreed that doctor–patient rapport was unimpaired with telemedicine. Of 165 patients, 61% had used telemedicine for the first time, 81% felt that their needs were met, 83% were satisfied with the quality of their care, and 88% had a positive experience. Overall, 83% patients vs. 45% physicians preferred telemedicine to a face-to-face clinic visit (p = 0.005). On univariate analysis, patients ≥ 65 years old had a greater positive telemedicine experience compared to patients < 65 years old (odds ratio 4.1 [1.2–13.8], p = 0.02). Conclusion: Both patients and physicians have a high rate of positive experiences with telemedicine. However, patients have a higher preference for telemedicine over face-to-face visits compared to physicians. In addition, elderly patients have more positive telemedicine experiences compared to younger patients.

550 Background: CEF and AC followed by paclitaxel (AC/T) are commonly used adjuvant regimens in women with early breast cancer. In a trial conducted by the EORTC, NCIC CTG, and SAKK three months of dose-dense EC was equivalent to six months of CEF in women with locally advanced breast cancer. We hypothesized that three months of a taxane following dose-dense EC would be superior to CEF alone or AC/T. The results of a planned interim analysis were presented in San Antonio 2006 (Abstract #53). We now present more detailed results on efficacy and toxicity. Methods: Women 60 years of age or younger, with axillary node positive or high risk node negative breast cancer were randomized to CEF, EC/T or AC/T for six months. Results: Between December 2000 and April 2005, 2104 patients were enrolled. The median follow-up is 30.4 months. Hazard ratios for recurrence are: AC/T vs. CEF, 1.49 (95% CI, 1.12–1.99), p=0.005; AC/T vs. EC/T, 1.68 (95% CI, 1.25–2.27), p=0.0006; and EC/T vs. CEF, 0.89 (95% CI, 0.64–1.22), p=0.46. Three year recurrence-free survival rates for CEF, EC/T, and AC/T are 90.1, 89.5 and 85.0%, respectively. There was no significant interaction between ER status and treatment. Multivariate analysis of predictive factors will be presented. The numbers of deaths are 50 (CEF), 47 (EC/T) and 65 (AC/T). There was more toxicity in CEF and EC/T compared to AC/T. Conclusion: AC/T given every three weeks, although less toxic is significantly inferior to CEF or EC/T in terms of relapse-free survival. It is too early to detect any difference between CEF and dose-dense EC/T. Our results indicate that there is still room to explore anthracycline and taxane adjuvant chemotherapy regimens.

Introduction: Fulvestrant has demonstrated efficacy in hormone receptor positive (HR+) metastatic breast cancer (mBC), both in first-and second-line settings. In clinical practice, however, fulvestrant has been used as a later-line therapy. This study assessed the efficacy of fulvestrant in women with mBC in early-versus later-line therapy. Methods: This retrospective cohort study assessed Saskatchewan women with HR+ mBC who received fulvestrant between 2003–2019. A multivariate Cox proportional survival analysis was performed. Results: One hundred and eighty-six women with a median age of 63.5 years were identified—178 (95.6%) had hormone-resistant mBC, 57.5% had visceral disease, and 43.0% had received chemotherapy before fulvestrant. 102 (54.8%) women received ≤2-line-therapy, and 84 (45.2%) received ≥3 line-therapy before fulvestrant. The median time to progression (TTP) was 12 months in the early-treatment vs. 6 months in the later-treatment group, p = 0.015. Overall survival (OS) from the start of fulvestrant was 26 months in the early-treatment group vs. 16 months in the later-treatment group, p = 0.067. On multivariate analysis, absence of visceral metastasis, HR: 0.70 (0.50–0.99), was significantly correlated with better TTP, whereas post-fulvestrant chemotherapy, HR: 0.32 (0.23–0.47), clinical benefit from fulvestrant, HR: 0.44 (0.30–0.65), and absence of visceral metastasis, HR: 0.70 (0.50–0.97), were correlated with better OS. Conclusions: Fulvestrant has demonstrated efficacy as both early-and later-line therapy in hormone-resistant mBC. Our results show that women with clinical benefit from fulvestrant, who received post-fulvestrant chemotherapy, or had non-visceral disease, had better survival.

Falls are a major issue among older adults with cancer and lead to interruptions in cancer treatment. Resistance and balance training can prevent falls in older adults, but minimal evidence is available regarding the older cancer population, who often have unique risk factors. We used a pre–post design to assess the feasibility of a remotely delivered exercise program that progressed in difficulty and its efficacy on lower body strength, balance, and falls in older adults with cancer who had prior in-person exercise experience. Twenty-six older adults with cancer completed the intervention. Attendance rate for the virtual component was 97.6% and for the independent component was 84.7%. Participants perceived the program as rewarding and enjoyable (100%), felt this program prepared them to exercise on their own (92%), were confident to continue exercising on their own (81%), and would recommend the program to other patients (100%). The median balance score at baseline and end-of-study was 4 (IQR = 0). The median chair-stand time decreased from 9.2 s (IQR = 3.13) to 7.7 s (IQR = 4.6). A statistically significant difference in lower body strength (r = 0.68, p = 0.001) was detected post-intervention. The findings from this study can inform the design of a larger randomized trial.

Background: Small intestine adenocarcinoma is a rare cancer. The current study aims to determine the outcomes of patients with small intestine adenocarcinoma in a Canadian province. Methods: This retrospective population-based cohort study assessed patients with small intestine adenocarcinoma who were diagnosed from 2008 to 2017 in Saskatchewan. A Cox proportional multivariate regression analysis was performed to determine the correlation between survival and exploratory factors. Results: 112 eligible patients with a median age of 73 years and M:F of 47:53 were identified. Overall, 75% had a comorbid illness, and 45% had a WHO performance status >1. Of the 112 patients, 51 (46%) had early-stage disease and 61 (54%) had advanced-stage disease. The median overall survival (mOS) was as follows: stage one, 59 months; stage two, 30 months; stage three, 20 months; and stage four, 3 months (p < 0.001). The median disease-free survival of patients with stage three disease who received adjuvant chemotherapy was 26 months (95% CI:23.1–28.9) vs. 4 months (0.0–9.1) with observation (p = 0.04). Patients who received chemotherapy for advanced disease had a mOS of 10 months (3.5–16.5) vs. 2 months (0.45–3.6) without chemotherapy (p < 0.001). In the multivariate analysis, stage four disease, hazard ratio (HR), 3.20 (1.84–5.40); WHO performance status >1, HR, 2.22 (1.42–3.45); lack of surgery, HR, 2.10 (1.25–3.50); and a neutrophil:lymphocyte ratio of >4.5, HR, 1.72 (1.10–2.71) were significantly correlated with inferior survival. Conclusions: Most patients with small intestine adenocarcinoma were diagnosed with advanced-stage disease. Advanced-stage disease, poor performance status, lack of surgery and a baseline neutrophil:lymphocyte ratio >4.5 were correlated with inferior survival.

Background: Breast cancer is rare in men. This population-based study aimed to determine outcomes of male breast cancer in relation to residence and other variables. Methods: In this retrospective cohort study, men diagnosed with breast cancer in Saskatchewan during 2000–2019 were evaluated. Cox proportional multivariable regression analyses were performed to determine the correlation between survival and clinicopathological and contextual factors. Results: One hundred-eight eligible patients with a median age of 69 years were identified. Of them, 16% had WHO performance status ≥ 2 and 61% were rural residents. The stage at diagnosis was as follows: stage 0, 7%; I, 31%; II, 42%; III, 11%; IV, 8%. Ninety-eight percent had hormone receptor-positive breast cancer. The median disease-free survival of urban patients was 97 (95% CI: 50–143) vs. 64 (46–82) months of rural patients (p = 0.29). The median OS of urban patients was 127 (94–159) vs. 93 (32–153) months for rural patients (p = 0.27). On multivariable analysis, performance status ≥ 2, hazard ratio (HR) 2.82 (1.14–6.94), lack of adjuvant systemic therapy, HR 2.47 (1.03–5.92), and node-positive disease, HR 2.32 (1.22–4.40) were significantly correlated with inferior disease-free survival in early-stage invasive breast cancer. Whereas stage IV disease, HR 7.8 (3.1–19.5), performance status ≥ 2, HR 3.25 (1.57–6.71), and age ≥ 65 years, HR 2.37 (1.13–5.0) were correlated with inferior overall survival in all stages. Conclusions: Although residence was not significantly correlated with outcomes, rural men had numerically inferior survival. Poor performance status, node-positive disease, and lack of adjuvant systemic therapy were correlated with inferior disease-free survival.
