Current recurrence detection is limited by non-specific methods such as blood testing and ultrasound. Based on reports that human epididymis four (HE4) \/ creatinine (CRE) ratios found in urine are elevated in ovarian cancers, we have developed a paper-based device that combines lateral flow technology and cell phone analysis to quantitatively measure HE4\/CRE. Surrogate samples were used to test the performance over clinically expected HE4\/CRE ratios. For HE4\/CRE ratios of 2 to 47, the percent error was found to be 16.0% on average whether measured by a flatbed scanner or\u00a0cell phone. There was not a significant difference between the results from the cell phone or scanner. Based on published studies, error in this method was less than the difference required to detect recurrence. This promising new tool, with further development, could be used at home or in low-resource settings to provide timely detection of ovarian cancer recurrence.<\/jats:p>","DOI":"10.1038\/s41598-021-01544-4","type":"journal-article","created":{"date-parts":[[2021,11,9]],"date-time":"2021-11-09T11:02:38Z","timestamp":1636455758000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Recurrence monitoring for ovarian cancer using a cell phone-integrated paper device to measure the ovarian cancer biomarker HE4\/CRE ratio in urine"],"prefix":"10.1038","volume":"11","author":[{"given":"Emily C.","family":"Kight","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iftak","family":"Hussain","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Audrey K.","family":"Bowden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Frederick R.","family":"Haselton","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,11,9]]},"reference":[{"key":"1544_CR1","doi-asserted-by":"publisher","first-page":"1102","DOI":"10.21037\/gs-20-544","volume":"9","author":"P Giampaolino","year":"2020","unstructured":"Giampaolino, P. et al.
