抄録 | We investigated differences in seminal vesicle (SV) length and interfractional SV motion relative to the prostate gland in prostate cancer patients. We compared 32 patients who received androgen deprivation therapy (ADT) before radiotherapy with 12 patients receiving radiotherapy alone at Okayama University Hospital in August 2008-July 2011. We examined the right and left SVs’ length and motion by computed tomography (CT) to determine the ADT’s effects and analyzed 347 CT scans in a multiple linear regression model. The ADT patients’ SV length was significantly shorter than the non-ADT patients’. The differences in right and left SV lengths between the ADT and non-ADT patients were 6.8 mm (95% CI 2.0-11.7 mm) and 7.2 mm (95% CI 3.1-11.3 mm) respectively in an adjusted regression model. SV motion did not differ between the ADT and non-ADT patients in terms of interfractional motion of the SV tips and the SVs’ center relative to the prostate gland. The ADT patients had significantly shorter SVs compared to the non-ADT patients, but no difference in SV motion was observed. SV interfractional motion should thus be compensated using the same planning margins, regardless of whether ADT is used.
