Focal treatment of prostate cancer
The embodiments include methods of treating prostate cancer by administering to a low grade unifocal prostate cancer tumor a composition comprising a therapeutically effective amount of pharmaceutically active ingredient capable of inducing necrosis of a low grade unifocal prostate cancer tumor, wherein administration reduces cancer incidence, cancer grade, and cancer progression (worsening) in the entire hemi-prostate where the initial focus was located and treated.
1. A method of reducing cancer incidence, reducing cancer grade, and reducing cancer progression in a mammal having a low grade unifocal prostate cancer tumor comprising: administering to the low grade unifocal prostate cancer tumor by intraprostatic injection directly to the low grade unifocal prostate cancer tumor a composition comprising a therapeutically effective amount of fexapotide triflutate (FT); wherein administering FT to only the low grade unifocal prostate cancer tumor reduces cancer incidence, reduces cancer grade, and reduces prostate cancer progression in the entire hemi-prostate where the initial low grade unifocal prostate cancer tumor was located and treated.
2. The method of claim 1 , wherein the method reduces hemi-prostate Gleason grade increase by an amount of from about 15% to about 100%, when compared to active surveillance, when measured at least 18 months after treatment.
3. The method of claim 2 , wherein the method reduces hemi-prostate Gleason grade increase by an amount of from about 45% to about 70%, when compared to active surveillance, when measured at least 18 months after treatment.
4. The method of claim 1 , wherein the method reduces new multifocal prostate cancer with Gleason grade increase in the entire hemi-prostate where the low grade unifocal prostate cancer tumor was located by:
a) an amount of from about 40% to about 100%, when compared to active surveillance, when measured at least 18 months after treatment;
b) an amount of from about 50% to about 90%, when compared to active surveillance, when measured at least 36 months after treatment; and
c) an amount of from about 15% to about 80%, when compared to active surveillance, when measured at least 48 months after treatment.
5. The method of claim 1 , wherein the method reduces new multifocal prostate cancer with an increase in Gleason grade primary pattern in the entire hemi-prostate where the low grade unifocal prostate cancer tumor was located by:
a) an amount of from about 50% to about 100%, when compared to active surveillance, when measured at least 18 months after treatment;
b) an amount of from about 45% to about 100%, when compared to active surveillance, when measured at least 36 months after treatment; and
c) an amount of from about 45% to about 100%, when compared to active surveillance, when measured at least 48 months after treatment.
6. The method of claim 1 , wherein the method reduces conventional cancer treatment and new multifocal prostate cancer with Gleason grade increase in the entire hemi-prostate where the low grade unifocal prostate cancer tumor was located by:
a) an amount of from about 40% to about 100%, when compared to active surveillance, when measured at least 18 months after treatment;
b) an amount of from about 50% to about 90%, when compared to active surveillance, when measured at least 36 months aftertreatment; and
c) an amount of from about 15% to about 80%, when compared to active surveillance, when measured at least 48 months after treatment.
7. The method of claim 1 , wherein the therapeutically effective amount of FT is within the range of from about 2.5 mg to about 20 mg.
8. The method of claim 1 , wherein the therapeutically effective amount of FT is within the range of from about 2.5 mg to about 15 mg.
9. The method of claim 1 , wherein the therapeutically effective amount of FT is 15 mg.
