How Cancer Treatment Evolved During a Decade
Doubtlessly we are living in an era of technology and medical sciences.
Today, medical sciences have been evolved so greatly that we are talking about
genome reading and modification. So, cancer treatment is not exceptional and we
will see how Cancer Treatment evolved
During a Decade.
2010: First Ever Cancer Vaccine
In 2010 FDA approved the first-ever Human Cancer Treatment Vaccine named sipuleucel-T. Basically
this is a way of treating the metastatic prostate cancer that no longer
responds to hormonal therapy using a patient's own immune system cells
(dendritic cells). It is worth mentioning this was the first and only human cancer
treatment vaccine ever approved globally.
2011: Ipilimumab
First time ever
in history, the FDA approved the usage of ipilimumab for treating melanoma.
Ipilimumab is a monoclonal antibody widely used for the treatment of inoperable
or metastatic melanoma. Ipilimumab triggers the immune system to attack cancer
cells by removing a "brake" that normally monitors the strength of the immune system and makes the immune system respond in a better manner.
2013:
Ado-Trastuzumab Emtansine (T-DM1)
FDA approved
ado-trastuzumab emtansine (T-DM1) for the treatment of patients with
HER2-positive breast cancer back in 2013. Mainly, this is being used for the
patients who took trastuzumab and/or a taxane drug for cancer treatment previously. T-DM1 is
an immunotoxin which is an antibody-drug conjugate and is made by chemically connecting
the monoclonal antibody trastuzumab with the cytotoxic agent mertansine. It blocks
the proliferation by avoiding the formation and generation of the microtubules.
2014:
Analysis of DNA for Cancer Treatment
Researchers from The Cancer Genome Atlas (TCGA)
which is a joint project of the NCI in collaboration with the National Human
Genome Research Institute to analyze the DNA and other molecular changes occurring
in more humans and this study was made for more than 30 types of cancers. In
order to find gastric (stomach) cancer is basically four different diseases,
not just one. On the basis of varying tumor characteristics, this result was
derived.
2014:
Pembrolizumab
In 2014, FDA
approved pembrolizumab for the treatment of chronic and last stage of melanoma.
This monoclonal antibody prevents the activity of a protein called PD1 on
immune cells. Consequently, it increases the strength of immune responses to
fight against cancer.
2015:
Talimogene Laherparepvec
FDA approves
talimogene laherparepvec (T-VEC) for the treatment of some patients with
metastatic melanoma that cannot be surgically removed. T-VEC, the first
oncolytic virus approved for clinical use works by infecting and killing tumor
cells and stimulating an immune response against cancer cells throughout the
body.
2016:
Cancer Moonshot
Congress passes
the 21st Century Cures Act, which provides funding for the Cancer Moonshot, a
broad program to enhance cancer research by investing in specific research
initiatives that have the potential to provide a better solutions for cancer care, diagnosis, and prevention.
2017:
Genomic Profiling Tests
In 2017, the FDA approved
two products to test tumors for genetic changes that can cause the tumors
susceptible to treatment with FDA-approved drugs. In November, FDA
authorizes the MSK-IMPACT test developed and used by Memorial Sloan
Kettering Cancer Center to analyze tumors for potential changes in 468
cancer-related genes. In December, FDA approves the FoundationOne CDx
test, which is performed to evaluate genetic changes in 324 genes that can
trigger cancer growth.
2018:
TCGA PanCancer Atlas
Researchers from NIH-funded
and TCGA performed genomic analysis of 33 cancer types. The PanCancer
Atlas gives a detailed genomic analysis of molecular and clinical data from
more than 10,000 tumors that give cancer researchers a revolutionary understanding
and learning of how, where, and why cancer grows in humans.
2020:
International Pan-Cancer Analysis of Whole Genomes
A panel of
international researchers analyze more than 2,600 genomes from 38 types of
cancer. They compared them with normal tissues to identify common patterns and
stages of molecular changes. The Pan-Cancer Analysis of Whole
Genomes study, which performed the research by using the data gathered by
the International Cancer Genome Consortium and TCGA, reveals the complex action
that keeps changing throughout the genome play in cancer treatment, development, growth, and spread.
