Effects of anatomical changes on pencil beam scanning proton plans in locally advanced NSCLC patients.

CONCLUSIONS: Daily anatomical variations over the course of treatment can cause considerable dose differences in the robust planned dose distribution. An advanced planning strategy including knowledge of anatomical uncertainties would be recommended to improve plan robustness against interfractional variations. For large anatomical changes, adaptive therapy is mandatory. PMID: 27393217 [PubMed - as supplied by publisher]
