Chemotherapy Procedure for Cancer Treatment in Delhi, India

Chemotherapy is a medical treatment which uses drugs to destroy or slow down the growth of cancer cells in the body. It can be given in various ways, including orally, through injections, or through IV infusions. The drugs can be given alone or in combination with other drugs or treatments, depending on the type and stage of the cancer. The drugs travel throughout the body and target rapidly dividing cells, including cancer cells, to stop or slow down their growth and prevent them from spreading to other body parts.

It can be used as a primary treatment for some types of cancer, such as leukaemia and lymphoma, or as a complementary treatment along with surgery or radiation therapy for other types of cancer. The effectiveness of chemotherapy depends on factors, including the type and stage of cancer, the dosage and frequency of the drugs, and the individual's overall health and response to the treatment.

Why is Chemotherapy used?

Here are some reasons why chemotherapy is used:

• To Shrink Tumours Before Surgery: It can be used to shrink tumours so that they can be surgically removed more easily.
• To Kill Cancer Cells After Surgery: It can be used after surgery to damage any remaining cancer cells.
• To Treat Cancer That Has Spread: Chemotherapy can be used to treat cancer that has spread to other parts of the body.
• To Relieve Symptoms: Chemotherapy can be used to shrink tumours that are causing symptoms such as pain, bleeding or blockages.

Conditions Treated By Chemotherapy

Here are some of the conditions for which Chemotherapy may be used:

Autoimmune Diseases

Chemotherapy can be used to treat autoimmune diseases such as lupus, rheumatoid arthritis, and multiple sclerosis. These diseases occur when the body's immune system attacks its own healthy cells, and chemotherapy drugs can help to suppress the immune system and reduce inflammation.

Blood Disorders

Chemotherapy can be used to treat blood disorders such as leukaemia, lymphoma, and multiple myeloma. These conditions involve abnormal growth and division of blood cells, and chemotherapy drugs can help to kill these abnormal cells.

Infectious Diseases

Chemotherapy can be used to treat certain infectious diseases such as tuberculosis and hepatitis C. These diseases are caused by viruses or bacteria that rapidly divide and grow, and chemotherapy drugs can help to kill these infectious agents.

Organ Transplantation

Chemotherapy can be used to suppress the immune system and prevent the rejection of transplanted organs. In some cases, chemotherapy may also be used to treat complications that arise after a transplant.

Bone Marrow Transplant

Chemotherapy is often used before a bone marrow transplant to prepare the patient's body for the transplant. This process is known as conditioning, and it aims to eliminate any cancer cells or abnormal cells in the bone marrow and to suppress the patient's immune system to prevent it from rejecting the transplanted cells.

Rare diseases

Chemotherapy may be used to treat rare diseases such as amyloidosis, which is a condition in which abnormal proteins build in organs and tissues. Chemotherapy drugs can help to kill the cells that produce these abnormal proteins.

Overall, while chemotherapy is most commonly associated with cancer treatment, it can also be used to treat a range of other conditions where abnormal cells are growing rapidly.

Types of Chemotherapy Drugs

The type of chemotherapy used depends on the type of cancer being treated and the stage of cancer.

Here are Common Types of Chemotherapy:

Alkylating Agents

These drugs work by attaching to DNA and preventing cancer cells from growing. Examples of alkylating agents include cyclophosphamide and chlorambucil.

Antimetabolites

These drugs mimic the structure of natural substances that cells need to grow and divide, and they interfere with the normal functioning of cancer cells. Examples of antimetabolites include methotrexate and fluorouracil.

Anthracyclines

These drugs work by damaging the DNA inside cancer cells. Examples of anthracyclines include doxorubicin and epirubicin.

Taxanes

These drugs interfere with the normal functioning of cancer cells by preventing the formation of microtubules, which are structures that help cells divide. Examples of taxanes include paclitaxel and docetaxel.

Platinum Compounds

These drugs work by binding to DNA and preventing cancer cells from growing. Examples of platinum compounds include cisplatin and carboplatin.

Topoisomerase Inhibitors

These drugs interfere with an enzyme called topoisomerase, which is involved in the replication of DNA. Examples of topoisomerase inhibitors include etoposide and irinotecan.

Monoclonal antibodies

These drugs are designed to target specific proteins on the surface of cancer cells, which can help to destroy the cancer cells. Examples of monoclonal antibodies include trastuzumab and rituximab.

Overall, while chemotherapy is most commonly associated with cancer treatment, it can also be used to treat a range of other conditions where abnormal cells.

How does Chemotherapy Treat Cancer?

Chemotherapy drugs work by damaging the DNA inside cancerous cells, which prevents them from dividing and growing. The drugs can also cause cancer cells to undergo apoptosis, a process in which the cells self-destruct. In addition to targeting cancer cells, chemotherapy drugs can also affect cells in the body that divide rapidly, such as hair follicle cells and cells in the lining of the digestive tract. It can cause side effects such as hair loss, nausea, and diarrhoea.

How are Chemotherapy Drugs Given?

Chemotherapy drugs can be given in several ways. The most common ways chemotherapy drugs are given are:

Intravenous (Iv) Infusion

The drugs are given through a vein in the arm or a central line, which is a catheter inserted into a large vein in the chest.

Oral Medications

The drugs are taken by mouth in the form of pills, capsules, or liquids.

Injections

The drugs are given through a needle injected into a muscle or under the skin.

Topical Application

The drugs are applied directly to the skin in the form of creams or gels.

Intrathecal Administration

The drugs are injected into the spinal fluid to treat cancer that has spread to the central nervous system. The method of drug administration depends on the specific

Topoisomerase Inhibitors

These drugs interfere with an enzyme called topoisomerase, which is involved in the replication of DNA. Examples of topoisomerase inhibitors include etoposide and irinotecan.

The method of drug administration depends on the specific chemotherapy drugs being used and the individual patient's medical needs. The frequency and duration of treatment may also vary depending on the cancer being treated and the patient's response to the chemotherapy drugs.
