    Abstract: e24105 Background: Cancer care has been severely affected by covid 19 pandemic leading to medical, ethical and organizational issues. Oncology healthcare professionals face challenges due to reorganization of cancer services and increasing health care requirements resulting in uncertainty and psychological stress. Aim of this study is to evaluate the impact of covid 19 pandemic on psychological well being of oncology clinicians in the MENA region. Methods: We randomly invited 1500 oncology clinicians including medical oncologists, clinical oncologists, radiation oncologists and surgical oncologists from 17 countries in the MENA region to complete a web based survey to determine the level of psychological stress during covid 19 pandemic from October 2020 to January 2021. The questionnaire was based on Perceived Stress Scale (PSS), Generalized Anxiety Disorders Scale (GAD-7) and WHO Well-being Index (WHO-5). The data was analyzed using SPSS version 21 and difference between groups was measured by T-test and ANOVA. Results: Overall 520 (35%) oncology clinicians including 368 (71%) males and 152 (29%) females participated in the survey. Most of the participants were medical oncologists (38%) from teaching institutions (76%) and the public sector (84%). 46% (n = 242) participants were 35-45 years of age. Majority of clinicians reported moderate (45.6%) to severe (42.3%) anxiety on GAD-7 scale. Females had statistically higher levels of anxiety (average score;15.46 ±4.87, p = 0.04). On PSS, the majority of participants reported higher stress with average scores (29.64 ±3.83) for males and (30.23 ±4.62) for females. Average score for WHO wellbeing index was 62.95 (±20.52) for males and 74.3 (±20.87) for females denoting a preservation of general well being, even in a higher stress and anxiety situation. Female gender was significantly associated with anxiety level on GAD-7 scale (p = 0.04), but this difference in stress level and well being was not observed on PSS (p = 0.134) and WHO well being index (p = 0.709). Clinicians of ages 25-35 years had significantly higher anxiety levels on GAD-7 scale (p = 0.004) and higher stress on PSS (p = 0.000). Age over 55 years was associated with lower levels of anxiety and stress on GAD-7 and PSS. Oncology clinicians working in public sector experienced significantly lower stress as compared to private sector on PSS scale (p = 0.041) Conclusions: Covid 19 pandemic has significantly increased the anxiety and stress levels among oncology clinicians in the MENA region. Anxiety and stress were higher in females and young clinicians. Clinicians over 55 years of age and oncologists working in the public sector reported less stress and anxiety. General well being of clinicians was well preserved even in a highly stressful and anxious situation.

    Utility of the Edmonton Frail Scale (EFS) in identifying frail elderly patients during treatment of colorectal cancer (CRC).
    American Society of Clinical Oncology (ASCO) ; 2012

    Abstract: e14001 Background: CRC is the second leading cause of cancer-related death, and 40-50% of patients are older than 70 years. Frailty is a concept that has been proposed by geriatricians as an indicator of functional age. The EFS is a 15 point incremental scale; it is quick ( 〈 5 min), and simple to administer. We conducted a pilot study to establish if the EFS would add utility beyond clinician’s expertise. The primary objective was to determine if there was an association between the EFS and receipt of chemotherapy. Methods: The EFS was administered to stage II-IV CRC patients ≥70 years, referred to a Medical Oncologist at a tertiary care centre. The EFS was completed by one of the investigators, with the treating oncology team blinded to results and a follow up 14 month chart review. Results: Forty-six patients were enrolled with the following characteristics: average age 76, 48% male, 78% performance status (PS) 0-1, and 21 (46%) started chemotherapy. The EFS was reproducible between visits (r = 0.81 [CI 0.64-0.9, p 〈 0.0001]). There was no correlation between the EFS and receipt of chemotherapy for the study population as a whole. As none of the 16 stage II patients had high-risk features requiring chemotherapy, the analysis was repeated excluding these patients. There was a reduced likelihood of receiving ch emotherapy for stage III/IV patients with higher EFS scores (Odds ratio 0.56 [CI 0.37-0.85, p 〈 0.01] per unit increment). A similar effect was observed after multivariable analysis (adjusting for PS, age, stage and gender, Odds ratio 0.41 [CI 0.18-0.96, p 〈 0.05] per unit increment). No correlation existed between EFS and upfront dose reductions, choice of less toxic regimens, or hospitalization secondary to grade 3/4 toxicities. Conclusions: This pilot study suggests the EFS can identify patients that Oncologists may have thought were too frail for chemotherapy, independent of PS. Therefore, the EFS has the potential to add a reproducible, and quantifiable measure of frailty to the clinician’s decision making armamentarium. The next study phase will employ the EFS real-time, and determine if using the EFS can minimize complications and unplanned health care utilization in elderly cancer patients.

    Abstract: 420 Background: Prior history of chronic medical conditions and medical treatment exposure has been significantly associated with the development and prognosis of different cancers. Population-based studies reported a reduced cancer-related mortality among patients with pancreatic cancer who were Statin or Metformin users as compared with non-users. We aimed to study the effect of antihypertensive medications on the survival outcome of pancreatic cancer. Methods: Under institutional ethical approval, medical records were reviewed and clinical characteristics at baseline (time of diagnosis) were retrieved. Blood pressure and antihypertensive medications use were documented including Angiotensin Converting Enzyme Inhibitor (ACEI), diuretics, Angiotensin Receptor Blockers (ARBs) and Beta-Blockers (BB). Hazard ratios (HRs) and 95% CIs were calculated by using Cox proportional hazard models with a backward stepwise selection procedure to identify independent prognostic factors for overall survival. Results: A total of 1,204 patients with adenocarcinoma of the pancreas were diagnosed at MD Anderson Cancer center between 1999 and 2009 were identified. The mean age value (± SD) is 61.9± 10 where 58.6% (N=705) were men and 87.5% (N=1,054) were white. The majority of patients were Caucasian (87%). 41.9% had metastatic disease. A total of 639 (53%) patients had chemotherapy with or without radiation. ACEI and diuretics use independently reduced all-cause mortality, ACEI by 24% with HR 0.76 (CI 0.63-0.91), and diuretics by 26% with HR 0.73 (CI 0.60- 0.89). Neither ARBs nor beta blockers use was statistically significant in reducing all-cause mortality (HR.80, CI 0.63 -1.0), BB HR 0.85 (CI 0.7-1.0). Conclusions: Our findings indicate a significant impact of anti-hypertensive medications including ACEI and diuretics on pancreatic cancer outcomes with improved survival in users versus non-users, this effect was independent of the cancer treatment received, tumour histology and site of metastasis. The potential antitumor activities of these agents in pancreatic cancer should be studied further.

    Abstract: e20522 Background: Frailty is traditionally assessed by a comprehensive geriatric assessment (CGA); there is no agreed upon standard for a CGA, and it is not feasible to implement in routine oncology practice. In contrast, the Edmonton Frailty Scale (EFS) is a simple questionnaire, requiring less than 5 minutes to complete, initially validated as a surrogate to the CGA in general medicine patients (Rolfson et al, 2006). We conducted a pilot study to establish if the EFS would add utility beyond clinician’s expertise. Methods: The EFS was administered to stage II-IV CRC patients ≥70 years, referred to a Medical Oncologist at a tertiary care centre. The EFS was completed by one of the investigators, with the treating oncology team blinded to results, and follow up of 14 months. Results: Forty-six patients were enrolled with the following characteristics: average age 76, 48% male, and 78% Zubrod performance status (PS) 0-1. The EFS was reproducible between visits (r = 0.81 [95%CI 0.64-0.9], p 〈 0.01). No association existed for the EFS and receipt of chemotherapy for the study population as a whole, however none of the stage II patients had features requiring chemotherapy. Restricting the analysis to stage III/IV patients demonstrated a reduced likelihood of receiving chemotherapy with higher EFS scores (Odds ratio 0.56 per unit increment [95%CI 0.37-0.85] p 〈 0.01). A similar effect was observed after multivariate analysis (adjusting for PS, age, stage and gender, Odds ratio 0.41 per unit increment [95%CI 0.18-0.96] p 〈 0.05). The clinician’s qualitative impression was associated with the EFS (p 〈 0.01). No association existed between the EFS and upfront dose reductions, choice of less toxic regimens, or hospitalization secondary to grade 3/4 toxicities. Conclusions: The EFS can identify patients that Oncologists may have thought were too frail for chemotherapy, independent of PS. The EFS has the potential to add a reproducible, and quantifiable measure of frailty to aid in decision making in oncology practice.

    Abstract: e17532 Background: Stage III NSCLC represents a heterogeneous population. Patients with good performance status (PS) and weight loss 〈 10% (WL 〈 10) are generally considered for radical treatment with chemoradiation or trimodality approaches. Outcome data from Cancer Care Ontario show 30% of stage III NSCLC (6th edition TNM) patients receive chemoradiation.There is significant variation between local health networks. We examined the proportion of patients with stage III NSCLC suitable for radical treatment. Methods: We conducted a retrospective cohort study of patients diagnosed with stage III NSCLC at the Juravinski Cancer Center from July 2007 to June 2009. Demographic, pathologic and treatment data were abstracted from patients’ records. The primary outcome was the proportion of stage III NSCLC patients eligible for radical treatment. We also compared patients treated radically versus palliatively. Results: 159 stage III NSCLC patients (staged by 6th edition TNM) were seen. The median age was 69 yrs (sd 12) with 58% men and 42% women. There were 40% stage IIIA, 37% IIIB and 23% IIIB (wet). 61 (38%) patients were treated with radical intent and 98 (62%) were treated palliatively. Reasons for palliative treatment approach were WL 〉 10% (7%), PS 〉 2 (10% ), both WL 〉 10% and PS 〉 2 (20%), significant comorbidities (9%),patient declined (9%) and stage IIIB wet(23 %).The median OS for patients treated radically was 23.3 months v 7.1 months for those treated palliatively. Stage IIIA patients treated radically had better OS than IIIB (27m v 14m). Patients with poor PS, or WL 〉 10% had similar OS to patients with wet stage IIIB (7.1m v 7.2m), whereas the survival of patients with poor PS and WL 〉 10% was worse (3m). Conclusions: Using eligibility criteria from clinical trials of stage III NSCLC, only 40% of patients appear eligible for radical treatment approaches. Our data are consistent with published data. Significant WL 〉 10% or poor PS ( 〉 2) predicted poor outcome. Combined WL 〉 10% and poor PS predicted a very poor prognostic group. Criteria for radical treatment of stage III NSCLC should not be extrapolated beyond the eligibility criteria used in clinical trials.

    Abstract: 3548 Background: Colon cancer is potentially curable by surgery in the early stages of the disease. Adjuvant chemotherapy improves disease-free and overall survival in patients with stage III disease, but the magnitude of benefit in stage II colon cancer is less clear. A previous Cochrane systematic review and meta-analysis (SR/MA) found improved disease-free, but not overall survival (Figueredo et al., 2008). An updated SR/MA was performed to determine the effects of adjuvant chemotherapy on disease-free and overall survival in patients with stage II colon cancer. Methods: Relevant databases (MEDLINE, EMBASE, and Cochrane) were independently searched by all authors, using the same search strategy employed in the original study (1/1988 to 9/2012). Randomized trials containing data on stage II colon cancer patients undergoing adjuvant 5-fluorouracil (5FU) chemotherapy versus observation were included. Pooled results were expressed as hazard ratios (HR) whenever possible, or risk ratios (RR), with 95% confidence intervals (95%CI) using a random effects model. Results: Seven studies were identified, and included in the final SR/MA. Six of the 7 studies were included in the disease-free survival analysis (n=4587). Adjuvant 5FU was associated with better disease-free survival (RR 0.84 (95%CI 0.75-0.94)). All 7 studies (n=5353) were included in the overall survival analysis showing an improvement with adjuvant 5FU (HR 0.87 (95%CI 0.78-0.97)). There was no evidence of heterogeneity across the studies (I 2 = 0% for all analyses). Conclusions: In stage II colon cancer, adjuvant 5FU chemotherapy statistically improves both disease-free and overall survival. Our SR/MA demonstrates, for the first time, an overall survival advantage with adjuvant chemotherapy in stage II colon cancer.
