Preclinical Experimental Screening Models For The Assessment Of Anti Cancer Drugs

Abstract

This study aimed to explore the correlation between durability and tumor petrification in patient with metastatic
interreelated cancer who had received cetuximab combined with chemotherapy. This study was single center retrospective
analysis that has been enlistment the 111 patients who had received the therapy in between April 2011 and October
2016.Tumor petrification and regimen efficacy were appraised sovereign by radiologists on the basis of computed
tomography scans. Associated between tumor petrification and clinical characteristics, tumor replication rate and patient
durability were analyzed. Among the 111 enrolled patients ,27 had tumor calcification ((27/111)(24.3%)).In the past decade,
TumorFlare Reaction (TFR) was considered as a new side effect associated with Immunomodulatory agents and as a
condition of chroniclymphaticleukemia(CLL) The incidence of TFR in CLL ranged from 28 to 58%umor response in
patient treated beyond progression was reported in 97% with prebrolizumab and in renal cell carcinoma 69% with
nivolumab. Rare life -threatening or fatal causes were reported, symptoms were usually mild. Therefore, the recognition
of suitable clinical benefit criteria in prospective trials for a better perception is compulsory. One of the most well known
method of inducing spontaneous regression of cancer is the application of Coley’s toxin(Heat -killed streptococcus
pyrogens and secratia marcescens) ,which has been used for the success full treatment of sarcoma, carcinomas, lymphomas,
myelomas, melanomas. use of Bacillus Chalmette Guerin vaccine is the treatment of urinary bladder cancer.
Bacteriolytic ,Bactofection therapy or treatment and bacteria directed enzyme therapy are the some of potential cancer
treatment modalities that use microorganisms.
