Question

Q12. Current clinical trials are exploring giving prostate cancer an SBRT delivery with a fractionation scheme of 40 Gy in fractions. Using the BED formalism, calculate the BED for this scheme then determine “ n ” the number of fractions of 2 Gy required to give a BED equal to than that calculated for the 40 Gy in 5 fraction regime. Assume that the a/B ratio for prostate cancer is 1.8 Gy. Note that the number of fractions must be given in integer numbers so consider rounding the n value up

Answer 1

Reduction of the patient and bowel motion subsidize to the doubt in dose distribution to prostate cancer patient. Tracing is a capable motion organization technique for lessening the indecision in the distribution of the deliberate dose delivery. Dosi-metric dimensions being achieved in order to describe and liken the presentation of couch and MLC following.

For prostate cancer patients treated with healing radiotherapy, the existence after metastatic development be contingent on the location of the primary metastasis. Lymph bulge metastasis had the greatest promising prognosis, signifying a dissimilar tumor ecology and suggesting that management be designated seeing the primary site of metastasis. If the first metastatic locations are lymph nodes, local conducts counting stereotactic radiotherapy to the metastatic nodes might meaningfully sluggish the degree of development of the illness.

Together following approaches were capable to upsurge the correctness of amount distribution. The quantity of development by following be contingent on the gesture design of the board. If the board shows almost no gesture, the alteration in presentation is insignificant.
