Liu et al reported the SAVE score to evaluate a male with a testicular tumor. One parameter for the score is the available testicular tissue volume not involved by tumor. The authors are from multiple institutions in China.
Parameters:
(1) length of tumor in cm
(2) width of tumor in cm
(3) height of tumor in cm
(4) length of testis in cm
(5) width of testis in cm
(6) height of testis in cm
(7) percentage of tumor in testis
volume of tumor in cubic cm =
= 0.52 * (length of tumor) * (width of tumor) * (height of tumor)
volume of testis in cubic cm =
= 0.71 * (length of testis) * (width of testis) * (height of testis)
available testicular tissue volume in cubic cm =
= (testicular volume) - ((percentage of tumor in testis) * (tumor volume))
