Ten each of prostate and head and neck (H&N) VMAT plans were considered for this study. Three types of errors were introduced into the original plans: gantry angle independent and dependent MLC errors, and gantry angle dependent dose error. The percentage difference in PTV-D95 between TPS and 3DVH was compared for no-error and error introduced plans.
For men with metastatic breast adenocarcinoma standard therapies typically involve the same therapies used for woman. Recently the FDA approved the aromatase inhibitor letrozole combined with the inhibitor of cyclin dependent kinase 4/6 (CDK4/6) palbociclib as first line therapy for women with metastatic breast cancer. Here we report a first case of a man with metastatic breast cancer whose tumor responded to palbociclib and letrozole. This combination might be effective for other men with metastatic breast cancer as well.

Consecutive patients treated for rectal cancer or adenomas in 4 colorectal centers in Brazil were included. Patients with early-stage rectal cancer identified by 3D-US were assigned to receive resection only, and those with a later stage were assigned to receive CRT. A second 3D-US was performed after CRT to detect the presence of residual tumor and metastatic lymph nodes or complete response.

Magnetic Resonance Imaging Targeted Biopsies alone are not Sufficient for Detection of Clinically Significant Prostate Cancer - A Systematic Review and Meta-Analysis

Magnetic resonance imaging targeted biopsies (MRI-Tbx) has the potential to detect significant prostate cancer with a small number of cores; however, there are concerns that some clinically significant (CS) cancers may not be visible on MRI or identified with targeted biopsies alone.
