Ninety nasopharyngeal cancer intensity-modulated radiation therapy (IMRT) plans and 60 rectal cancer volumetric modulated arc therapy (VMAT) plans were employed in this study. Of these, 20 nasopharyngeal cancer cases and 15 rectal cancer cases were randomly selected as the testing data. The DVH prediction was performed using two methods. One method applied the individual dose-volume histograms (IDVHs) induced by a series of fields with uniform-intensity irradiation and the other method applied the distance-to-target histogram and the conformal-plan-dose-volume histogram (DTH\u2009+\u2009CPDVH). The determination coefficient R<jats:sup>2<\/jats:sup> and mean absolute error (MAE) were used to evaluate DVH prediction accuracy. The PTV DVH prediction was performed using the IDVHs. The PTV dose coverage was evaluated using <jats:italic>D<\/jats:italic><jats:sub><jats:italic>98<\/jats:italic><\/jats:sub>, <jats:italic>D<\/jats:italic><jats:sub><jats:italic>95<\/jats:italic><\/jats:sub>, <jats:italic>D<\/jats:italic><jats:sub><jats:italic>1<\/jats:italic><\/jats:sub> and uniformity index (<jats:italic>UI<\/jats:italic>). The OAR dose was compared using the maximum dose, <jats:italic>V<\/jats:italic><jats:sub><jats:italic>30<\/jats:italic><\/jats:sub> and <jats:italic>V<\/jats:italic><jats:sub><jats:italic>40<\/jats:italic><\/jats:sub>. The significance of the results was examined with the Wilcoxon signed rank test. For PTV DVH prediction using IDVHs, the clinical plan and IDVHs prediction method achieved mean <jats:italic>UI<\/jats:italic> values of 1.07 and 1.06 for nasopharyngeal cancer, and 1.04 and 1.05 for rectal cancer, respectively. No significant difference was found between the clinical plan results and predicted results using the IDVHs method in achieving PTV dose coverage (<jats:italic>D<\/jats:italic><jats:sub><jats:italic>98<\/jats:italic>,<\/jats:sub><jats:italic>D<\/jats:italic><jats:sub><jats:italic>95<\/jats:italic>,<\/jats:sub><jats:italic>D<\/jats:italic><jats:sub><jats:italic>1<\/jats:italic><\/jats:sub> and <jats:italic>UI<\/jats:italic>) for both nasopharyngeal cancer and rectal cancer (<jats:italic>p<\/jats:italic>-values\u2009\u2265\u20090.052). For OAR DVH prediction, no significant difference was found between the IDVHs and DTH\u2009+\u2009CPDVH methods for the R<jats:sup>2<\/jats:sup>, MAE, the maximum dose, <jats:italic>V<\/jats:italic><jats:sub><jats:italic>30<\/jats:italic><\/jats:sub> and <jats:italic>V<\/jats:italic><jats:sub><jats:italic>40<\/jats:italic><\/jats:sub> (<jats:italic>p<\/jats:italic>-values\u2009\u2265\u20090.087 for all OARs). This work evaluates the performance of dosimetric information of several individual fields with uniform-intensity radiation for DVH prediction, and extends its application to PTV DVH prediction. The results indicated that the IDVHs method is comparable to the DTH\u2009+\u2009CPDVH method in accurately predicting the OAR DVH. The IDVHs method quantified the input features of the PTV and showed reliable PTV DVH prediction, which is helpful for plan quality evaluation and plan generation.<\/jats:p>","DOI":"10.1038\/s41598-021-82749-5","type":"journal-article","created":{"date-parts":[[2021,2,4]],"date-time":"2021-02-04T11:08:10Z","timestamp":1612436890000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Evaluation of dose-volume histogram prediction for organ-at risk and planning target volume based on machine learning"],"prefix":"10.1038","volume":"11","author":[{"given":"Sheng xiu","family":"Jiao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming li","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li xin","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiao-wei","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,2,4]]},"reference":[{"issue":"5","key":"82749_CR1","doi-asserted-by":"publisher","first-page":"e228","DOI":"10.1002\/mp.13562","volume":"47","author":"G Mahadevaiah","year":"2020","unstructured":"Mahadevaiah, G., Bermejo, I., Jaffray, D., Deller, A. & Wee, L.
