Purpose: The extent of symptoms of depression among patients with breast cancer compared with those without the disease is not well documented in Ethiopia and other sub-Saharan African countries.

Materials and methods: This study examines the prevalence of symptoms of depression in women with breast cancer (n = 436) compared with those without breast cancer (n = 856) in Addis Ababa, Ethiopia, through a comparative cross-sectional study using a validated questionnaire, the Patient Health Questionnaire-9. The association between breast cancer diagnosis and symptoms of depression was evaluated using a multivariable binary logistic regression model.

Results: About 39.2% of women with breast cancer had some level of symptoms of depression compared with 23.8% of women without the disease. By severity of symptoms of depression, 13.1% of women with breast cancer reported moderate to severe symptoms of depression compared with 6.8% of women without the disease. Sixty-three percent of women with breast cancer reported difficulties performing routine daily activities, compared with 36.7% of women without the disease. In the multivariable-adjusted model, women with breast cancer were 2 times (adjusted odds ratio, 2.26 [95% CI, 1.49 to 3.44]) more likely to report symptoms of depression compared with those without the disease. Likewise, women with breast cancer were 4.78 (95% CI, 3.51 to 6.52) times more likely to report difficulty in performing routine daily activities compared with women without the disease.

Conclusion: Four in 10 women with breast cancer in Addis Ababa reported having symptoms of depression, which was considerably higher than women in the general population. This finding emphasizes the importance of addressing psychosocial needs among women with breast cancer to enhance quality of life and potentially extend longevity.

Purpose: Cancer recurrence is an important long-term outcome of cancer survivors that is often not routinely collected and recorded by population-based registries. In this study, we review population-based studies to determine the current availability, landscape, and infrastructure of long-term outcomes, particularly metastatic recurrence, in women initially diagnosed with nonmetastatic breast cancer (MBC).

Methods: We reviewed the literature to identify studies that used population-based registry data to examine the distribution of metastatic recurrence in women diagnosed with non-MBC. Data on outcomes and methods of ascertainment were extracted. Registry infrastructure including sources and funding was also reviewed.

Results: A total of 23 studies from 11 registries in eight countries spanning Europe, North America, and Oceania were identified and included in the review. Most studies were retrospective in nature and collected recurrence data only for ad hoc studies rather than as part of their routine registration. Definition of recurrence and data sources varied considerably across studies: the cancer-free time interval between the start of follow-up and risk window ranged from the diagnosis of primary tumor (n = 7) to 6 months from diagnosis (n = 1); the start of follow-up differed between initial diagnosis (n = 16) and treatment (n = 7).

Conclusion: Cancer surveillance should encompass outcomes among survivors for research and monitoring. Studies are underway, but more are needed. Cancer registries should be supported to routinely collect recurrence data to allow complete evaluation of MBC as an outcome to be conducted and inform health care providers and researchers of the prognosis of both nonmetastatic and metastatic patients with breast cancer.

Purpose: This study aimed to develop a multivariable, weighted overall survival (OS) risk score (SRS) for nonmetastatic (M0) invasive breast cancer (M0-BC, SRS_M0-BC).

Materials and methods: This study included a training (1,890 patients) and a validation cohort (850 patients) from the Reggio Emilia Cancer Registry (RE-CR). Ten traditional prognostic variables were evaluated.

Results: In the training set, all the variables but the human epidermal growth factor receptor were significantly associated with OS at univariable analysis. A multivariable model identified an increased death risk for estrogen receptor (hazard ratio [HR], 2.0 [95% CI, 1.1 to 3.1]; P = .021), tumor stages T2-T3 (HR, 2.4 [95% CI, 1.3 to 4.7]; P = .009) and T4 (HR, 5.1 [95% CI, 2.0 to 13.0]; P < .001), and age >74 years (HR, 5.7 [95% CI, 4.0 to 8.2]; P < .001). By assigning scores according to HRs, four risk categories were generated (P for trend <.001). The HRs of death in the high- (282 patients, 15.6%), intermediate-high (275 patients, 15.2%), and intermediate-risk (349 patients, 19.2%) categories patients were, respectively, 27.3, 12.9, and 3.5 times higher, compared with the low-risk (909 patients, 50%) group. Harrell'C index was 81.1%, and the explained variation in mortality was 66.6. Internal cross-validation performed on the accrual index dates yielded a Harrell'C index ranging from 79.5% to 82.3% and an explained variation in mortality ranging from 60.3% to 69.4%. In the validation set, the same risk categories (P for trend <.001) were devised. The Harrell'C index and the explained variation in mortality were 76.1% and 53.7%, respectively, in the whole cohort, maintaining an elevated percentage according to the two accrual index dates.

Conclusion: SRS_M0-BC using the real-world RE-CR data set may represent a low-cost, accessible, globally applicable model in daily clinical practice, helping to prognostically stratify patients with invasive M0-BC.

Purpose: To develop and implement a continuing professional development (CPD) activity focused on geriatric assessment (GA) in oncology for oncologists and geriatricians. We evaluated the impact of this activity on knowledge, skills, and performance regarding GA in oncology, as well as its feasibility and acceptability.

Methods: We included teams composed of an oncologist and a geriatrician working in Mexico. Curriculum content was selected from geriatric oncology guidelines. We used Project Extension for Community Healthcare Outcome (ECHO)'s model to create a 12-week online course. A one-group pretest post-test quasi-experimental design was used to evaluate the intervention's effectiveness. At baseline, participants answered a multiple-choice knowledge assessment, a survey on self-perceived competence in GA, and an adaptation of the Association for Community Cancer Centers Geriatric Oncology Gap Assessment Tool, evaluating self-perceived performance in conducting geriatric interventions. These assessments and a satisfaction questionnaire were also completed postintervention. Baseline and postintervention scores were compared using paired t-tests.

Results: We included 40 participants (20 oncologists and 20 geriatricians). Median attendance was 10 sessions (range 2-12). Thirty-eight participants completed the satisfaction questionnaire, with a median score of 10/10 (range 8-10). The mean baseline and postintervention knowledge scores were 59.5 ± 12.8 and 74.4 ± 9.7, respectively (P < .001, effect size 1.14). The mean baseline and postintervention competence scores were 6.42 ± 2.5 and 9.02 ± 0.8, respectively (P < .001, effect size 1.03). The mean baseline and postintervention performance scores were 2.58 ± 0.65 and 3.29 ± 0.5, respectively (P < .001, effect size 1.64).

Conclusion: A CPD activity for oncologists and geriatricians on the basis of the Project ECHO model was feasible and acceptable, leading to increased knowledge, competence, and performance in geriatric oncology. This could represent a novel method for increasing the geriatric competence of the cancer care workforce in Latin America and globally.

Purpose: This study aims to clarify the benefit of adjuvant chemotherapy (AC) in resectable cholangiocarcinoma (CCA) and develop a predictive risk score for treatment selection.

Methods: Patients with resected CCA undergoing curative surgery, with or without AC, were identified from three centers in Thailand. Patients with R2 resection and 30 days postoperative death were excluded. Using the largest center as the discovery cohort, we generated propensity score matching (PSM). A predictive model for overall survival (OS) was identified, and a predictive risk score was developed from the PSM discovery cohort, classifying patients into high- and low-risk groups. The proposed risk score was validated in the other two centers.

Results: In the discovery cohort, 493 patients were identified. After PSM, 328 patients were categorized into surgery (n = 164) and surgery + AC (n = 164) groups. The baseline characteristics in the PSM discovery cohort were well-balanced. In the validation cohort (n = 83), patients with positive lymph node 1 received AC more frequently than those under observation (47% v 18%; P = .02). A MINT pathologic risk score was developed from multivariate analysis for OS. The score includes margin, perineural invasion, pathologic nodal status, and pathologic tumor size. In the PSM discovery cohort, for the low-risk score group, the surgery group had significantly longer OS compared with the surgery + AC group (49.4 v 31.5 months; hazard ratio [HR], 1.78 [95% CI, 1.11 to 2.86]; P = .016). Conversely, for the high-risk score group, the surgery + AC group had better OS than the surgery group (18.8 v 8 months; HR, 0.60 [95% CI, 0.46 to 0.79]; P < .001). The results were comparable in the validation cohort.

Conclusion: Patients with resected CCA with a high-risk MINT pathologic risk score were likely to benefit from AC, whereas those with a low-risk score were not. Further validation in a larger prospective cohort is warranted.

Purpose: Gallbladder cancer (GBC) is a biliary tract malignancy characterized by its high lethality. Although the incidence of GBC is low in most countries, specific areas such as Chile display a high incidence. Our collaborative study sought to compare clinical and molecular features of GBC cohorts from Chile and the United States with a focus on ERBB2 alterations.

Methods: Patients were accrued at Memorial Sloan Kettering Cancer Center (MSK) or the Pontificia Universidad Católica de Chile (PUC). Clinical information was retrieved from medical records. Genomic analysis was performed by the next-generation sequencing platform MSK-Integrated Mutation Profiling of Actionable Cancer Targets.

Results: A total of 260 patients with GBC were included, 237 from MSK and 23 from PUC. There were no significant differences in the clinical characteristics between the patients identified at MSK and at PUC except in terms of lithiasis prevalence which was significantly higher in the PUC cohort (85% v 44%; P = .0003). The prevalence of ERBB2 alterations was comparable between the two cohorts (15% v 9%; P = .42). Overall, ERBB2 alterations were present in 14% of patients (8% with ERBB2 amplification, 4% ERBB2 mutation, 1.5% concurrent amplification and mutation, and 0.4% ERBB2 fusion). Notably, patients with GBC that harbored ERBB2 alterations had better overall survival (OS) versus their ERBB2-wild type counterparts (22.3 months v 11.8 months; P = .024).

Conclusion: The prevalence of lithiasis seems to be higher in Chilean versus US patients with GBC. A similar prevalence of ERBB2 alterations of overall 14% and better OS suggests that a proportion of them could benefit from human epidermal growth factor receptor type 2-targeted therapies. The smaller cohort of Chile, where the disease prevalence is higher, is a reminder and invitation for the need of more robust next-generation sequencing analyses globally.

Purpose: To report the patterns of care for brain metastases (BMs) in the Federation of Asian Organizations for Radiation Oncology (FARO).

Methods: Overall, 37 questions were prepared. The survey was conducted online using Google Forms, and the URL was distributed to members of the FARO research committee. Radiation oncologists associated with FARO responded to the questionnaire between May 2023 and June 2023, and their answers were analyzed.

Results: Responses were received from 32 radiation oncologists in 13 countries participating in FARO. Twenty-six physicians (81.3%) were affiliated with academic centers, and 22 (68.8%) were able to perform stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (fSRT) for BMs at their institution. The most typically used prognostic index for BM was the recursive partitioning analysis classification (17 physicians, 53.1%). The maximum number of BMs indicated for SRT/SRS was ≤three (11 physicians, 34.4%), whereas eight (25.0%) physicians answered for 6-10 BMs. The maximum size of BMs considered for SRS/fSRT was ≤3 cm (14 physicians, 43.8%), whereas nine (28.1%) answered that SRS/fSRT was preferred if the maximum size was >4 cm. When whole-brain radiotherapy (RT) was indicated, hippocampal avoidance and memantine usage were limited to 50.0% and 25.0% of patients, respectively. The most typical RT modality after BM resection was SRS/fSRT alone, regardless of whether the margin was positive (19 physicians, 59.4%) or negative (13 physicians, 40.6%).

Conclusion: We report the survey results of the patterns of care for BMs in the FARO. This survey was conducted only among a limited number of FARO members. Since many respondents were affiliated with relatively large-scale academic centers, large-scale surveys, including community hospitals, are warranted for future initiatives.
