Abstract
INTRODUCTION In the National University Cancer Institute, Singapore (NCIS), 2 pilot programs providing (i) surgical prehabilitation before cancer surgery and (ii) geriatric oncology support for older adults planned for chemotherapy and/or radiotherapy were merged to form the Geriatric Oncology Longitudinal End to eNd (GOLDEN) program in 2019 to support patients from the time of their cancer diagnosis, through their treatment process, to cancer survivorship. METHODS AND MATERIALS Older adults aged ≥65 years were enrolled in either surgical prehabilitation, the geriatric medical oncology (GO) arm, or both. All patients undergo a geriatric assessment. We assessed if patients had a change in treatment plans based on GOLDEN recommendations, and the impact on patient related outcomes. RESULTS There were 777 patients enrolled in the GOLDEN program over 2 years; 569 (73%) were enrolled in surgical prehabilitation, 308 (40%) were enrolled in the GO arm, with 100 (12.8%) enrolled in both. 56.9% were females. Median age was 73. Lower gastrointestinal (51.2%) and hepatobiliary cancers (24.1%) were the most common cancer types. 43.4% were pre-frail and 11.7% were frail. Of the 308 patients in the GO arm, 86.0% had geriatric syndromes, while 60.7% had a change in their treatment plans based on GOLDEN recommendations. 31.5% reported an improved global health status, while 38.3% maintained their global health status. 226 (73%) responded that they had benefited from the GOLDEN. CONCLUSION More than half of the population was either pre-frail or frail. Amongst those in the GO arm, the majority had geriatric syndromes and had a change in their treatment plans based on GOLDEN recommendations. Majority reported either improvement or maintenance in global health status, with most feeling they have benefited from the program. Further evaluation of the longitudinal geriatric hematology-oncology program for cancer-related outcomes and sustainability should be carried out.

Abstract
IMPORTANCE The Cancer and Aging Research Group (CARG) prediction model for chemotherapy-related toxic effects has been developed but not yet validated in older Asian adults. In view of differences in drug metabolism and toxic effect reporting in the Asian population, the ability of this tool to guide the cancer treatment decision-making process in older Asian adults needs to be assessed. OBJECTIVE To examine the validity of the CARG predictive model in a multiethnic Asian cohort of older adults. DESIGN, SETTING, AND PARTICIPANTS In this prognostic study, patients of various Asian ethnicities 70 years or older with a solid tumor diagnosis receiving chemotherapy at the National University Cancer Institute, Singapore, were accrued from June 1, 2017, to January 1, 2019. Their risks of chemotherapy-related toxic effects were calculated using the CARG tool. A geriatric assessment was performed, and the treating oncologist (blinded to the CARG scores) was asked to give an estimated likelihood of toxic effects (low, medium, or high). Chemotherapy-related toxic effects were recorded during each clinic visit. Validation of the prediction model was performed by calculating the area under the receiver operating characteristic curve. Multivariate analyses were performed to identify variables in other domains in the geriatric assessment predicting for severe toxic effects. MAIN OUTCOMES AND MEASURES Grade 3 to 5 toxic effects and hospitalization. RESULTS The study included 200 patients (median age, 74 years [range, 70-89 years]; 110 [55.0%] male; 177 [88.5%] Chinese, 17 [8.5%] Malay, 4 [2.0%] Indian, and 2 [1.0%] other ethnicities [according to Singapore's national system of race classification]). A total of 137 patients (68.5%) experienced grade 3 to 5 toxic effects, and 131 (65.5%) required hospitalization. The area under the receiver operating characteristic curve for the CARG chemotoxicity prediction model was 0.74 (95% CI, 0.67-0.82), retaining good discrimination in the study population. CONCLUSIONS AND RELEVANCE This prognostic study conducted in a multiethnic Asian cohort of older adults supports the validity of the CARG predictive model in this population, predicting which older adults are at risk of chemotherapy-related toxic effects.

Abstract
55 Background: Prehabilitation in older patients aged ≥ 65 years undergoing cancer surgery and systemic therapy is crucial in reducing treatment complications and improving physical health, psychological well-being, quality of life (QOL) and cancer-related outcomes. However, a majority of older patients (80%) attending our Geriatric Oncology (GO) One-Stop clinic do not receive same day Comprehensive Geriatric Assessment (CGA)-directed Allied Health Interventions (AHI) for prehabilitation during their First Visit (FV). Objectives: The objective of this study is to increase the uptake of same day CGA-directed AHI for prehabilitation from 20% to 60% using telehealth. Methods: Older patients planned for an FV at the GO One-Stop clinic in an academic tertiary center, the National University Cancer Institute, Singapore (NCIS) were recruited. Our workflow was revised so that all FV patients underwent CGA via telehealth prior to the physical visit. Based on the preliminary CGA findings, a multidisciplinary geriatric oncology board planned for prehabilitation interventions which would be performed on the same day as the physical visit. Interim follow-up via telehealth by GO nurses helped to monitor patients for treatment-related toxicities and development of new geriatric syndromes. QOL was assessed during the FV and 3 months later. Results: Two hundred seventy-five patients were recruited from July 2020 to January 2022. 60% (n = 165) received prehabilitation interventions in the One-Stop clinic. The average time spent per visit was shortened from 4 hours to 2.5hours, but completed interventions on same day rose from 1 to 3. The proportion of patients who responded that they benefited from the program on the patient satisfactory survey remained high at 96%. 84.8% were satisfied with the hybrid telehealth model and 80.8% of them reported a maintained or improved QOL after being enrolled into the program. Conclusions: Adoption of telehealth for CGA is a feasible and effective method in improving prehabilitation interventions uptake for GO patients. GO hybrid model of care is a sustainable practice with no additional cost incurred.

Abstract
e24029 Background: The Geriatric 8 (G8) questionnaire has been validated predominantly in Western populations as a screening tool to identify vulnerable older adults with cancer who would benefit from comprehensive geriatric assessment (CGA). Given the paucity of evidence of the performance of this tool in a multi-ethnic Asian population, there is a need to determine whether the established cut-off score of 14 should be adjusted for improved performance in this population of older adults. Methods: Prospective cross-sectional study was done in older adults aged ≥ 65 years in the outpatient setting of an academic tertiary cancer center, the National University Cancer Institute, Singapore (NCIS). G8 questionnaire and CGA were conducted for eligible patients. The performance of the G8 screening tool in identifying patients who would benefit from a CGA was evaluated using receiver operating characteristic (ROC) curve analysis: area under the curve (AUC), sensitivity (Sn), and specificity (Sp). Results: 180 participants (mean age 74 years) were included in the study. 40.5% were female. 90% were Chinese, 7% were Malay, 2% were Indian. 57.8% were pre-frail and 12.8% were frail. The top five cancers in our study population were colorectal (30%), lung (25%), head and neck (12%), upper gastrointestinal (10%) and gynecological (7.0%). ROC analysis showed an AUC of 0.73 (95% CI 0.65 – 0.80) with an optimal cut-off score of 13 (Sn 71.7%, Sp 74.0%). Conclusions: G8 performed well in identifying older adults with cancer who would benefit from a CGA, in a multi-ethnic Asian population. In our cohort, we found that a slightly lower cut-off score of 13 performed better, and should be taken into consideration as part of daily oncology practice in Asia. Future research efforts should go into examining the biological aspects of frailty in this population.

Abstract
12043 Background: Older adults are at an increased risk of chemotherapy related toxicities. Identification of risk factors can facilitate oncologists in tailoring treatment, potentially mitigate the risk of chemotherapy toxicity and improve social economic outcomes. Tools like the Karnofsky Performance Status (KPS) and Geriatric Assessment (GA) are used in clinical practice to guide treatment decisions for older adults with cancer. The CARG model incorporating the GA and clinical variables was developed and validated to predict for grade 3-5 toxicities, although this has not yet been validated in Asians. Methods: Patients ≥70 years old with solid malignancies receiving chemotherapy at the National University Cancer Institute, Singapore were recruited between June 2017 and January 2018. The study aims to verify the application of the CARG model, KPS, GA and oncologists’ estimate of toxicity in a multi-ethnic Asian population. The risks of chemotherapy toxicity were calculated using the CARG model (low risk: 0-5, medium risk: 6-9, high risk: ≥10). A GA including a physician rated KPS score (low risk: 90-100, medium risk:80, high risk: ≤70) and a timed up and go (TUG) test (low risk: ≤12s, high risk: > 12s) were performed for all patients. The attending oncologist (blinded to the CARG score) was asked to give an estimated likelihood (low/medium/high) of chemotoxicity. Chemotherapy related toxicities were captured by chart review based on the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The area under the receiver operating characteristic (ROC) curve and a univariate analysis of predictors of toxicity were calculated. Results: A total of 200 patients were included. Median age was 74 (range: 70-89). The ethnic makeup of the population consisted of Chinese (N = 177; 88.5%), Malay (N = 17; 8.5%), Indians (N = 4; 2%) and other ethnicities. Majority of patients were males (N = 110; 55%), had metastatic disease at diagnosis (N = 114; 57%) and had gastrointestinal cancers (N = 80; 40%). 75% (N = 150) had polychemotherapy and 55% (N = 110) received full dose chemotherapy. More than half of patients (68.5%) experienced G3-5 toxicities, with 65.5% requiring hospitalization. The CARG model predicted 22.5% of patients as low, 50.5% as medium and 27% as high risk of chemotoxicity. The area under ROC for the CARG model was 0.74 (95% CI, 0.67-0.82). A one-point increase in the CARG score was associated with a 15% increase in the odds of G3-5 toxicities. 84.5% of patients needed > 12s for the TUG test. The TUG score, KPS and oncologist’s prediction of toxicity was predictive of an increased risk of G3-5 toxicities (p < 0.01). Conclusions: This study confirms the validity of the CARG predictive model in Asians and can streamline healthcare delivery in older adults. Development of a more robust predictive model incorporating the KPS and TUG into the CARG model could be considered.

Abstract
Introduction The COVID-19 pandemic has impacted healthcare on an unprecedented scale, with healthcare resources being channeled into managing the devastating effects of the outbreak. Healthcare provision for vulnerable older adults has also been affected by lockdowns and suspension of selected medical services worldwide. In our tertiary cancer center, the National University Cancer Institute, Singapore (NCIS), our Geriatric Oncology (GO) service for older adults with cancer was halted for five months. In this paper, we describe the adoption of a hybrid telemedicine model by our GO service to continue care provision for older adults in the midst of the pandemic. Materials and Methods Comprehensive geriatric assessments (CGA) were done via telemedicine and virtual multidisciplinary discussions were held prior to the patients' clinic visits. A hybrid telemedicine consultation allowed geriatricians and oncologists, segregated in different sites during the pandemic, to provide a hybrid physical and video geriatric oncology consultation. Scheduled phone follow ups by GO nurses helped to monitor patients for treatment-related toxicities and geriatric syndromes. Results Two hundred fifty patients were enrolled in the program from July 2020 to August 2021. All were assessed with a CGA, with 240 receiving interventions in the one-stop clinic. The average amount of time spent per visit was shortened from four hours to two and a half hours with an average of three interventions on the same day, versus one previously. Of the patients who received interventions, 84.8% were satisfied with the hybrid telemedicine model and 80.8% of them had reported a maintained or improved quality of life after being enrolled in the program. Discussion Telemedicine has been widely adopted during the pandemic, but older adults with limited digital literacy may find it a challenge. Our hybrid telemedicine model has allowed us to continue to provide cancer care, identify issues brought about by social isolation, and render timely assistance. It has become imperative to adapt, prepare and plan for the challenges we may face amid the ongoing COVID-19 pandemic and similar future outbreaks. Only by doing so can we remain agile and resilient, to continue providing quality care to our older patients with cancer.

Abstract
Salvage therapy for recurrent high grade gliomas (HGG) includes surgery, radiotherapy and chemotherapy, however, standard treatment does not exist. We evaluated the tolerability and efficacy of re-irradiation (re-RT) with hyperthermia (HT) for patients with recurrent HGG. From September 2010 to July 2015, 20 patients with recurrent HGG were treated with re-RT and HT. The radiotherapy dose of 30 Gray (Gy) was delivered with 2 Gy per fraction daily, and HT was performed twice weekly. Primary endpoints were treatment compliance and toxicity. Second endpoints were overall survival (OS) and progression free survival (PFS). The median interval between initial RT and re-RT was 11 months. During re-RT with HT, there were no significant acute morbidities over grade 3. Median overall survival (OS) from re-irradiation was 8.4 months and the 6 and 12 months survival rate were 67% and 30%, respectively. The median progression free survival (PFS) from re-irradiation was 4.1 month. Our findings suggested that concurrent re-RT with HT was a safe and well-tolerated. In addition, the combination re-RT and HT could be a valuable salvage treatment option for selected recurrent HGG patients with poor performance status.

Abstract
Abstract
Purpose: To evaluate the treatment outcomes of radiotherapy (RT) for breast cancer with ipsilateral supraclavicular (SCL) and/or internal mammary (IMN) lymph node involvement.
Methods: A total of 353 patients from 11 institutions were included. One hundred and thirty-six patients had SCL involvement, 148 had IMN involvement, and 69 had both. All patients received neoadjvant systemic therapy followed by breast conserving surgery or mastectomy, and postoperative RT to whole breast/chest wall. As for regional lymph node irradiation, SCL RT was given to 344 patients, and IMN RT to 236 patients. The median RT dose was 50.4 Gy.
Results: The median follow-up duration was 61 months (range, 7-173). In-field progression was present in SCL (n=20) and/or IMN (n=7). The 5-year disease-free survival (DFS) and overall survival rates were 57.8% and 75.1%, respectively. On multivariate analysis, both SCL/IMN involvement, number of axillary lymph node ≥4, triple negative subtype, and mastectomy were significant adverse prognosticators for DFS (p = 0.022, 0.001, 0.001, and 0.004, respectively). Regarding the impact of regional nodal irradiation, SCL RT dose ≥54 Gy was not associated with DFS (5-yr rate, 52.9% vs. 50.9%, p = 0.696) in SCL-involved patients, and the receipt of IMN RT was not associated with DFS (5-yr rate, 56.1% vs. 78.1%, p = 0.099) in IMN-involved patients.
Conclusion: Neoadjuvant chemotherapy followed by surgery and postoperative RT achieved an acceptable in-field regional control rate in patients with SCL and/or IMN involvement. However, a higher RT dose to SCL or IMN RT was not associated with the improved DFS in these patients.
