Type and timing of systemic therapy use predict overall survival for patients with brain metastases treated with radiation therapy.

INTRODUCTION: This study aimed to investigate whether systemic therapy (ST) use surrounding radiation therapy (RT) predicts overall survival (OS) after RT for patients with brain metastases (BMs). METHODS: Provincial RT and pharmacy databases were used to review all adult patients in British Columbia, Canada, who received a first course of RT for BMs between 2012 and 2016 (n = 3095). Multivariate analysis on a randomly selected subset was used to develop an OS nomogram. RESULTS: In comparison to the 2096 non-recipients of ST after RT, the median OS of the 999 recipients of ST after RT was 5.0 (95% Confidence interval (CI) 4.1-6.0) months longer (p < 0.0001). Some types of ST after RT were independently predictive of OS: targeted therapy (hazard ratio (HR) 0.42, CI 0.37-0.48), hormone therapy (HR 0.45, CI 0.36-0.55), cytotoxic chemotherapy (HR 0.71, CI 0.64-0.79), and immunotherapy (HR 0.64, CI 0.37-1.06). Patients who discontinued ST after RT had 0.9 (CI 0.3-1.4) months shorter median OS than patients who received no ST before or after RT (p < 0.0001). In the multivariate analysis of the 220-patient subset, established prognostic variables (extracranial disease, performance status, age, cancer diagnosis, and number of BMs), and the novel variables "ST before RT" and "Type of ST after RT" independently predicted OS. The nomogram predicted 6- and 12-month OS probability and median OS (bootstrap-corrected Harrell's Concordance Index = 0.70). CONCLUSIONS: The type and timing of ST use surrounding RT predict OS for patients with BMs.

Effects of High Anxiety Scores on Surgical and Overall Treatment Plan in Patients with Breast Cancer Treated with Neoadjuvant Therapy.

BACKGROUND: Patients with newly diagnosed breast cancer and high levels of anxiety often pursue more aggressive surgical interventions. The neoadjuvant treatment (NAT) setting could provide a window of opportunity to address patients' anxiety. However, the impact of anxiety on surgical decisions in the setting of NAT for breast cancer has not been previously studied. MATERIALS AND METHODS: A prospective database of patients with breast cancer treated with NAT at BC Cancer was used to identify patients treated with NAT and subsequent surgical resection. Patients with bilateral breast cancer or BRCA mutations or those referred to the hereditary cancer program were excluded. An anxiety score of 0-3 was assigned based on responses to the Edmonton Symptom Assessment System and Psychosocial Screen for Cancer. Clinicopathological information and treatment data were retrieved and cross-referenced between the low-anxiety (scores 0-1) and high-anxiety (scores 2-3) cohorts. RESULTS: From 2012 to 2016, 203 patients met eligibility criteria. Of these, 93 patients (45.8%) had low anxiety and 110 patients (54.2%) had high anxiety. Overall, 161 patients (79.3%) had locally advanced cancers; no differences in stage, grade, or biomarkers were found between the low- and high-anxiety cohorts. Patients with high self-reported anxiety at initial consultation were younger (mean 56 years vs. 60 years; p = .011) and more likely to undergo mastectomy for breast-conserving surgery-eligible disease and bilateral mastectomy for unilateral disease compared with those with low anxiety (37.3% vs. 18.3%; likelihood ratio 9.15; p = .002). No significant differences in treatment timelines were identified between the two cohorts. CONCLUSION: Patients with high anxiety at initial consultation were nine times more likely to undergo aggressive surgery compared with patients with low anxiety. These findings underscore the need for early identification of patients who may benefit from tailored supportive and educational services to address sources of anxiety and knowledge gaps. IMPLICATIONS FOR PRACTICE: The prevalence of anxiety among women with newly diagnosed breast cancer is being increasingly acknowledged. However, health care providers have not fully appreciated the impact of anxiety on the surgical management of patients with early-stage breast cancer. This study highlights the importance of self-reported anxiety on surgical management. The preoperative period provides a unique window of opportunity to address sources of anxiety and provide targeted educational materials over a period of 4-6 months, which may ultimately lead to less aggressive surgery when it is not needed.

Supportive care and healthcare service utilisation in older adults with a new cancer diagnosis: a population-based review.

OBJECTIVES: Older adults have unique needs and may benefit from additional supportive services through their cancer journey. It can be challenging for older adults to navigate the siloed systems within cancer centres and the community. We aimed to document the use of supportive care services in older adults with a new cancer diagnosis in a public healthcare system. METHODS: We used population-based databases in British Columbia to document referrals to supportive care services. Patients aged 70 years and above with a new diagnosis of solid tumour in the year 2015 were included. Supportive care services captured were social work, psychiatry, palliative care, nutrition and home care. Chart review was used to assess visits to the emergency room and extra calls to the cancer centre help line. RESULTS: 2014 patients were included with a median age of 77, 30% had advanced cancer. 459 (22.8%) of patients accessed one or more services through the cancer centre. The most common service used was patient and family counselling (13%). 309 (15.3%) of patients used community home care services. Patients aged 80 years and above were less likely to access supportive care resources (OR 0.57) compared with those 70-79 years. Patients with advanced cancer, those treated at smaller cancer centres, and patients with colorectal, gynaecological and lung cancer were more likely to have received a supportive care referral. CONCLUSIONS: Older adults, particularly those above 80 years, have low rates of supportive care service utilisation. Barriers to access must be explored, in addition to novel ways of holistic care delivery.

Characterizing female infectious syphilis cases in British Columbia to identify opportunities for optimization of care.

Introduction: The rate of infectious syphilis continues to increase among females in British Columbia (BC) and Canada, raising concerns of increased incidence of congenital syphilis. We characterized syphilis cases among females in BC to identify opportunities to prevent syphilis and optimize its care. Methods: All cases of infectious syphilis diagnosed in BC between March 13, 2018 and December 31, 2020 and reported as female gender were reviewed. Demographics, risk factors and concurrent conditions were collected from a provincial surveillance system. Subgroup analyses comparing cases with and without housing instability, substance use, mental illness and a recent sexually transmitted infection (STI) were conducted to understand differences between these subgroups. Statistical associations were calculated using chi-square or t-tests. Results: There were 226 reported cases of female infectious syphilis in BC during this period: 38 (16.8%) in 2018; 74 (32.7%) in 2019; and 114 (50.4%) in 2020. Mean age was 32 years (range 15-75 years). Of those who reported concurrent conditions, most cases had experiences with housing instability (71.1%), substance use (68.2%) and mental illness (83.9%), while 42.9% had a recent STI. Cases who reported housing instability or substance use were significantly more likely to have experiences with a recent STI, street involvement, transactional sex, mental illness and income assistance (all p<0.01). Conclusion: Our findings highlight the importance of fostering an enabling environment for syphilis care. Concurrent services to support individuals with syphilis as well as housing instability, substance use and mental illness, may help prevent syphilis and improve wellbeing.

Efficacy of Neoadjuvant Endocrine Therapy Versus Neoadjuvant Chemotherapy in ER-positive Breast Cancer: Results From a Prospective Institutional Database.

BACKGROUND: Although neoadjuvant chemotherapy (NACT) has been established as a standard for medically fit patients with locally advanced breast cancer, there has been renewed interest in utilizing neoadjuvant endocrine therapy (NET) for women with estrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. Rates of pathologic complete response (pCR) are known to be low, but data regarding down-staging and long-term outcomes are inconsistent. PATIENTS AND METHODS: A prospective institutional database of patients with breast cancer treated with neoadjuvant therapy from 2012 to 2017 was analyzed to identify patients with estrogen receptor-positive, human epidermal growth factor receptor 2-negative breast cancer. Patients who received NET were compared with those who received NACT. A matched analysis (age, stage, grade) was performed to compare rates of down-staging, pCR, breast conserving surgery, and CPS+EG scores. RESULTS: A total of 176 patients met eligibility criteria. Of these, 111 (63%) patients received NACT, 51 (29%) received NET, and 14 (8%) received both sequentially. Women prescribed NET were older (65.5 vs. 51.2 years; P < .0001) and presented with lower clinical stage (P < .0001). The median duration of NET was 90 days. When matched, clinical down-staging was more frequent with NACT (20/51; 39%) compared with NET (11/51; 22%) (P = .032). Of these, 2% achieved pCR in each cohort. Conversion rates to breast conserving surgery eligibility were low (8% and 13% with NET and NACT; P = .70). No significant differences in CPS+EG scores were identified. CONCLUSIONS: Significantly higher rates of down-staging were achieved with NACT compared with NET when patients were matched. This study highlights the importance of establishing tumor biology and the need for biomarkers that can be used as predictive tools to inform treatment.
