Healing Beyond Hope: Beating Cancer with Modern Treatments

Hope is necessary to survive. But when it comes to cancer, hope becomes secondary. The primary is the proper and effective treatment to beat it down. There are various conventional ways to treat cancer. The available options consist of hormone therapy, radiation therapy, chemotherapy, and surgery. These options can kill the cancer cells and prevent them from spreading to other organs. But healthy cells are even affected by these. Imagine, what if there is any method we can target the gene which is responsible for cancer growth, or minimize side-effects on healthy cells. Scientists have discovered such a way to do that. To beat cancer with modern treatment, the discovery of targeted gene therapy has made its way into medical oncology. This therapy not only targets specific genes or proteins for cause cancer but also reduces the harm to healthy cells. Let's talk in detail about this therapy:

Targeted Gene Therapy

Targeted gene therapy is a kind of cancer treatment that targets specific genes or proteins that are responsible for the growth and proliferation of cancer. This therapy destroys cancer cells without damaging healthy cells.
During diagnosis, your oncologists concluded by considering your reports that the cause of cancer is a gene mutation or change. These mutations can cause abnormal changes in healthy cells and convert them into cancer cells. Then, your oncologist uses the targeted gene therapy to target the gene causing abnormalities. He may consider this therapy as a specific drug.

In What ways does Targeted Gene Therapy Destroy Cancer Cells?

Human cells divide to reproduce and grow under genetic instructions. But when there is a mutation in a gene, it becomes unable to process the normal function of cell cycle and division. There, it results in abnormal cell division. That further causes generation of cancer cells.
First, the Oncologist will study the genetic mutation that triggers cancer cells. Then, he will decide the target cell or center to trigger the mutated gene. He may focus on the cell’s surface or the nucleus inside the cell. After that, they will develop a specific drug to damage the cancer cells. This target drug will kill the cancer cell by inhibiting the abnormal signals by a specific gene.
Most targeted gene therapy specifically kills the cancer cell by targeting its malfunctioning proteins. The working mechanisms depend on the cancer detected. The following are a few of the listed mechanisms:
• Promotes the immunity and immune cells to fight the cancer cells
• Inhibits the chemical signals that help cancer cells to grow and proliferate
• Blocks the formation of blood vessels that provide nutrients for the growth and multiplication of cancer cells.
• Elevates the cancer cell apoptosis (Cell death)
• Restrict the release of hormones that are necessary for cancer cells to proliferate.
• Delivers toxins and cancer-killing chemicals to cancer cells to stop their growth

Type of Targeted Gene Therapy

Various types of targeted drugs can be used in gene therapy. Oncologists prescribe them by considering patients' condition, stage diagnosis, mutation type, and body response to the drug. Here are a few examples of targeted gene therapy medications:

Immunotherapy Drugs: These medications trigger the immune system, which in turn kills cancer cells. It is an advanced way to enhance the antibodies so that they can damage cancer cells. Avastin 400mg Injection is a type of monoclonal antibody. It is available at Magicine Pharma. It is an online pharmacy that deals with anticancer drugs. They offer a heavy discount on the medicine purchase.
CAR T Cell Therapy: It is a Chimeric antigen receptor (CAR) T-cell therapy which is used to treat cancer. Doctor creates specific lab-made gene to antibody. These modified antibody help to kill cancerous cells.
Antibody-Drug Conjugates: It is a combination of chemotherapy with targeted gene therapy. This method kills the specific malignant cells without any damage to normal and healthy cells.
Small-Molecule Drugs: These are the small molecular drugs that focus on the mechanisms of cancer cells and disturb their proliferation and growth.
Bispecific Antibodies: They are specifically engineered proteins designed to bind to two different antigens.

Targeted Cancer

There are moreover, 200 types of cancer, but some of them can be treated with this therapy. Your oncologist will decide if it must be used.
• Kidney cancer
• Thyroid cancer
• Bladder cancer
• Cervical cancer
• Colorectal cancer
• Esophageal cancer
• Endometrial cancer
• Head and neck cancer
• Bone and soft tissue cancers
• Skin cancers (Melanoma and squamous cell carcinoma)
• Blood cancer (Multiple myeloma, acute leukemia, and non-Hodgkin lymphoma)

Way to have Therapy:

Doctors give targeted gene therapy by considering the patient's medical history, diagnosed cancer, stage of cancer, and body response to medicines. There are 3 ways to take gene therapy.
• IV (Intravenously)
• Injection shot
• Tablet or capsule

Potential side effects

​

The human body shows some undesired symptoms while taking anticancer medicine. Some of them are manageable, but if you observe them continually, consult with your doctor.
Some of the common side effects that are shown after treatment with targeted gene therapy are mentioned below:
• Diarrhea
• Blood clots
• Blood in stools
• Skin Inflammation
• High blood pressure
• Slow wound healing
• Increased levels of liver enzymes
• Infection in the lungs and respiratory passages

Target Gene Therapy and Chemotherapy

If we compare targeted gene therapy to chemotherapy, it is possible to reach the conclusion that targeted gene therapy is much better than chemotherapy. As it is highly selective or specific while killing cancer cells without damaging healthy cells. But not everyone or every cancer accepts treatment with this therapy. It depends on the patient's cancer stage, diagnosed cancer, and response. Additionally, sometimes, targeted gene therapy and chemotherapy are combined to kill the cancer cells and make the treatment more effective.
Modern Advancement in Cancer Treatment
Every cell in the human body comprises DNA, which is made up of millions of base pairs. These base pairs comprise and make the genetic sequences. These sequences are highly fragile and specific. Simple damage can disturb their sequence and cause variations in gene function. It is also responsible for cancer-causing gene impairment. To deal with this, scientists have discovered a solution. This innovative solution focuses on gene editing through the CRISPR-CAS9 tool and Oncolytic Virotherapy to kill selective and specific cancer cells. It also focuses on creating recombinant cancer vaccines, developing recombinant-engineered T cells via CAR-T therapy, and using gene therapy to suppress oncogenes.

Conclusion

The development of targeted gene therapy is undoubtedly a hopeful breakthrough in the battle against cancer. If, somehow, it becomes possible to treat mutation by this method, it will be possible to control the genetic cause of cancer. Researchers are continually working to decode the genetic signals to prevent their spread from generation to generation. It will also make treatment more improved and effective. There are various drugs available in the market that are used in targeted gene therapy. You can find them on Magicine Pharma. You may visit the website and share your prescription to get your targeted gene therapy drug.
