Abstract Prevention and treatment of hypertension (HTN) are a challenging public health problem. Recent evidence suggests that artificial intelligence (AI) has potential to be a promising tool for reducing the global burden of HTN, and furthering precision medicine related to cardiovascular (CV) diseases including HTN. Since AI can stimulate human thought processes and learning with complex algorithms and advanced computational power, AI can be applied to multimodal and big data, including genetics, epigenetics, proteomics, metabolomics, CV imaging, socioeconomic, behavioral, and environmental factors. AI demonstrates the ability to identify risk factors and phenotypes of HTN, predict the risk of incident HTN, diagnose HTN, estimate blood pressure (BP), develop novel cuffless methods for BP measurement, and comprehensively identify factors associated with treatment adherence and success. Moreover, AI has also been used to analyze data from major randomized controlled trials exploring different BP targets to uncover previously undescribed factors associated with CV outcomes. Therefore, AI-integrated HTN care has the potential to transform clinical practice by incorporating personalized prevention and treatment approaches, such as determining optimal and patient-specific BP goals, identifying the most effective antihypertensive medication regimen for an individual, and developing interventions targeting modifiable risk factors. Although the role of AI in HTN has been increasingly recognized over the past decade, it remains in its infancy, and future studies with big data analysis and N-of-1 study design are needed to further demonstrate the applicability of AI in HTN prevention and treatment.

212 Background: Preoperative factors that reliably predict lymph node (LN) metastases in pancreatic neuroendocrine tumors (PanNETs) are unclear. The number of LNs needed to accurately stage PanNETs has not been defined. Methods: Patients who underwent curative-intent resection of primary non-functional PanNETs at 8 institutions from 2000-2016 were analyzed. Tumors with poor differentiation and Ki-67 > 20% were excluded. Preoperative factors associated with LN metastases were identified. A procedure specific target for LN retrieval to accurately stage patients was determined. Results: Of 2182 pts with GI NETs, 695 underwent resection of PanNETs. 33% of tumors were proximal (head/uncinate), and 67% were distal (neck/body/tail). 26% of pts (n = 158) had LN+ disease, which was associated with worse 5-yr recurrence-free survival (RFS) (60% vs 86%; p < 0.001). Increasing number of +LNs was not associated with worse RFS. Preoperative factors associated with +LNs included tumor size ≥2 cm (OR 6.6; p < 0.001), proximal location (OR 2.5; p < 0.001), moderate vs well differentiation (OR 2.1; p = 0.006), and Ki-67≥3% (OR 3.1; p < 0.001). LN metastases were also present in tumors without these risk factors: < 2cm (9%), distal location (19%), well differentiated (23%), and Ki-67 < 3% (16%). Median LN retrieval was 13 for pancreatoduodenectomy (PD), but only 9 for distal pancreatectomy (DP). Given that PD routinely includes a complete regional lymphadenectomy, a minimum number of LNs to accurately stage pts was not identified. For DP, however, removal of < 7 LNs failed to discriminate 5-yr RFS between LN (+) and (-) pts ( < 7 LNs: 72% vs 83%, p = 0.198; ≥7 LNs: 67% vs 86%, p = 0.002). Conclusions: Tumor size ≥2 cm, proximal location, moderate differentiation, and Ki-67≥3% are preoperative factors that predict LN positivity in resected non-functional PanNETs. Given the 9-23% incidence of LN metastases in patients without such risk factors, routine regional lymphadenectomy should be considered. Pancreatoduodenectomy inherently includes sufficient LN retrieval, while distal pancreatectomy should aim to remove ≥7 LNs for accurate staging.
