Impact Of Decision-Support System And Guideline Treatment Concordance On Response Rate In Advanced Lung Cancer.
JOURNAL OF CLINICAL ONCOLOGY(2019)
摘要
e20006 Background: Clinical decision-support systems (CDSS) provide up-to-date evidence to practitioners overwhelmed by the deluge of clinical findings. Few studies, however, have evaluated their impact on patient outcomes. This cross-sectional retrospective study was conducted to: 1) measure concordance of real-world clinical decisions with therapeutic options from the IBM Watson for Oncology (WfO) CDSS and the Chinese Society of Clinical Oncology (CSCO) guidelines, 2) the effect of concordance on objective response rate (ORR). Methods: Health records from patients receiving 1 st line treatment at Peking University International Hospital Oncology Center in China between January 2016 and December 2018 (69 stage IV NSCLC, 30 with SCLC) with documented tumor progression after 2+ cycles of treatment, were reviewed to determine concordance of actual treatment with WfO therapeutic options and CSCO guidelines. Patients’ treatments were grouped as concordant with: WfO+CSCO, WFO only, CSCO only, or neither. ORR, defined as partial or complete response after 2+ treatment cycles (RECIST criteria)was determined for each group. Results: For NSCLC, ORR ranged from 21.4% for discordance with both WfO and CSCO to 100.0% for WfO only concordance. For SCLC, ORR ranged from 37.5% for CSCO only concordance to 73.3% for WfO+CSCO concordance (Table). The main reasons for discordance were: 1 st generation TKIs like Gefitinib and Erlotinib (vs. Osimertinib) are standard of care for EGFR mutant patients in China, (2) Local CSCO guideline drugs like Lobaplatin and Icotinib are not included in WfO. Conclusions: This study provides preliminary evidence to suggest that treatment concordance with WfO may be associated with improved ORR in some cases of NSCLC (WfO only) and SCLC (WfO + CSCO). ORR in NSCLC patients who were discordant with both WFO and CSCO guidelines was the lowest at 21.4%. Larger studies are needed to understand the effect of guideline and WfO concordance on ORR.
