The research objective was to obtain a fast/simple analytic solution for previously published Radiotherapy Tumor Control Probability (TCP) Integral Model by other authors. Finding, firstly, is new/simpler Function than Poisson distribution of survival clonogens which developed from classical biological model algebraic/numerically modified equation. Solution obtained this alternative based on Bi...

 Background: To analyze the dosimetric and radio biologic advantages between intensity modulated radiotherapy (IMRT) and 3 dimensional conformal radiotherapy (3DCRT) and selection of optimal photon energy for IMRT treatments. Material and methods: 24 patients with localized prostate carcinoma were planned for 3DCRT and IMRT techniques. Radiation dose of 54 Gy with 2 Gy/fraction, was planned to ...

A triple-variable Integral Equation for Tumor Control Cumulative Probability (TCCP) is developed with the addition of important radiotherapy Treatment-Time parameter. Based on a previous double TCCP depending Biological Model parameters (α , β ), NEffective model implemented in (TCP) equation. Results comprise three essential Radiation Therapy precise determination TCCP. Solution shows method t...

background : meningiomas are common benign tumors of the central nervous system. patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. this study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. materials and met...
