9022 Background: High quality education is crucial for hematology/oncology (H/O) training and lifelong learning. However, H/O has historically prioritized clinical and research careers over medical education careers. Consequently, few programs support H/O educators. A CoP is a group that shares “a concern or passion for something they do and learn how to do it better as they interact regularly.” We formed the ASCO Med Ed CoP in 2021 to provide a collaborative network and professional development venue for H/O educators. Methods: Following a published framework for developing a global health professions educator community (Establish-Grow-Sustain), we (ASCO Education Scholars Program graduates) developed CoP mission and vision statements and a leadership structure (Establish), formed committees and projects (Grow), and gathered at the ASCO Annual Meeting and via virtual Town Halls (Sustain). In 2023, we collected demographics and evaluated the CoP using a logic model focused on inputs, activities, outputs, and impact. Results: As of December 2023, the CoP includes 238 members from 143 institutions (38 [27%] non-U.S.): 207 (87%) ASCO members; 127 (53%) women, 106 (45%) men, 5 (2%) no response (NR); 111 (47%) White, 88 (37%) Asian/Pacific Islander, 27 (11%) Latinx/Hispanic, 12 (5%) Black/African-American, 8 (3%) Middle Eastern, 1 (0.4%) African, 16 (7%) NR; 146 (61%) hematologist/oncologists, 68 (29%) trainees, 6 (3%) radiation oncologists, 3 (1%) surgical oncologists, and 15 (6%) other professionals. The logic model is displayed (Table). Conclusions: The CoP has had an impact on its members, ASCO, and beyond and continues to grow and sustain itself by recruiting broadly, driving projects forward, and making structural adjustments for long-term sustainability. Upcoming projects include providing more educational resources and measuring outcomes such as changes in members’ knowledge, skills, and attitudes. Membership diversity continues to be a challenge and a priority. [Table: see text]

Abstract Background: Overexpression of COX-2 has been associated with worse outcome in NSCLC. In C30203, we found that administration of the selective COX-2 inhibitor celecoxib in addition to chemotherapy in advanced NSCLC improved outcome (progression free and overall survival, PFS, OS) in pts with moderate to high COX-2 expression by immunohistochemistry (IHC). C30801 was designed to prospectively confirm that finding. Patients and Methods: Pts with NSCLC (stage IIIb with pleural effusion, IV 6th ed) were pre-registered and biopsy specimens analyzed for COX-2 by IHC. Pts with COX-2 expression > or = 2, PS 0-2 and normal organ function were eligible. Chemotherapy was determined by histology: carboplatin (AUC = 6), pemetrexed (500 mg/m2) d 1, q21 days for pts with non-squamous NSCLC; carboplatin(AUC=5.5) d1, gemcitabine (1000 mg/m2) d 1,8 for pts with squamous histology. Randomization was to celecoxib (400 mg bid) (Arm A) or placebo (Arm B). The primary endpoint was to demonstrate improvement in PFS in patients with COX-2 index >=4 with hazard ratio of 0.645. Results: The study was halted by the DSMB for futility after 312 of the planned 322 pts were randomized. The current analysis is based upon the first 300 pts. There were no significant differences between the groups (Table). There was a possible harmful effect for COX-2 inhibition in the COX-2 2-3 subset (OS HR = 1.75, p =.0977). Toxicity was similar for both arms. Subset analyses evaluating histology, chemotherapy regimen, incremental COX-2 expression did not demonstrate any advantage for COX-2 inhibition. Conclusions: 1. COX-2 expression by IHC failed to select pts who could benefit from selective COX-2 inhibition. 2. COX-2 inhibition did not significantly increase toxicity associated with chemotherapy or increase cardiovascular morbidity. 3. We will evaluate other possible determinants of toxicity and response to COX-2 inhibition.
