NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note “no longer under consideration” will appear above).
Peer-review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a “Peer-Review Me” button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed “version of record” (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Concordance Study Between IBM Watson for Oncology and real clinical practice for Cervical cancer patients in Chinaï¼ša Retrospective analysis.
Watson for Oncology (WFO) is a artificial intelligence clinical decision-support systems with evidence-based treatment options for oncologists. WFO has been gradually used in China, but limited reports on whether WFO is suitable for Chinese patients.
This study aims to investigate the concordance of treatment options between WFO and real clinical practice at the Second Xiangya Hospital Cancer Center for Cervical cancer patients retrospectively.
We retrospectively enrolled 300 cases of cervical cancer patients who were hospitalized at the Second Xiangya Hospital Cancer Center from May 2017 to August 2018. WFO provide treatment options for 246 supported cases. Real clinical practice were defined as concordant if treatment options were designated â€œrecommendedâ€ or â€œfor considerationâ€ by WFO. Concordance of treatment option between WFO and real clinical practice was analysed statistically.
Treatment concordance between WFO and real clinical practice occurred in 72.8% (179/246) of cervical cancer cases.Logistic regression analysis showed that rural registration residence [0.64(0.427-0.946), P=0.025], advanced age [0.08(0.03-0.28), P=0.032], poor ECOG performance status [0.29(0.083-1.058), P=0.048], stages II-IV disease ([2.08 (1.002-4.325), P=0.046], [2.09(1.001-4.381), P=0.047], [0.19(0.038-0.91), P=0.025], respectively) have remarkable impact on consistency.Pathological type, differentiation degree, lymphatic and distant metastasis were not found to affect concordance.The main reasons attributed to the 27.2% (67/246) of the discordant cases were the substitution of nedaplatin for cisplatin,reimbursement plan of bevacizumab, surgical preference,and absence of neoadjuvant/adjuvant chemotherapy and PD-1/PD-L1 antibodies recommendations.
WFO recommendations were in 72.8% of concordant with real clinical practice for cervical cancer patients in China. However, several localization and individual factors limit its wider application. So,WFO could be an essential tool but it cannot currently replace oncologists.To be rapidly and fully apply to cervical cancer patients in China, accelerate localization and improvement were needed for WFO.
