What Is Chemotherapy?

Chemotherapy is a systemic cancer treatment that uses medicines known as anticancer drugs to destroy cancer cells or slow their growth. Cancer cells generally divide and multiply more rapidly than many normal cells, making them more susceptible to certain chemotherapy medicines.

Depending on the type, stage, and biological characteristics of cancer, chemotherapy may be used as the primary treatment or combined with surgery, radiation therapy, immunotherapy, or targeted therapy.

Chemotherapy may be given with different treatment goals. Neoadjuvant chemotherapy is administered before surgery or radiation therapy to shrink a tumour, while adjuvant chemotherapy is given after surgery to eliminate microscopic cancer cells and reduce the risk of recurrence.

In advanced or metastatic cancer, chemotherapy may help control disease progression, relieve symptoms, and improve quality of life.

Chemotherapy Procedure

Before starting chemotherapy, the oncologist evaluates the patient’s overall health, cancer type and stage, laboratory investigations, organ function, and previous treatments. This assessment helps determine the appropriate chemotherapy drugs, dosage, treatment schedule, and route of administration.

Chemotherapy can be administered through different routes. Intravenous (IV) chemotherapy is commonly delivered through a vein, sometimes using a central venous catheter or port for repeated treatment.

Certain chemotherapy medicines can also be administered orally as tablets or capsules. The choice depends on the specific cancer and treatment protocol.

Chemotherapy is usually given in cycles.

A cycle consists of a treatment period followed by a recovery period, allowing healthy tissues to recover before the next dose. The number and frequency of cycles vary according to the cancer type, treatment intent, drug combination, and individual response.

During treatment, patients are monitored for side effects and changes in blood counts, kidney function, liver function, and other relevant parameters. The oncologist may adjust the dosage or treatment schedule when medically necessary.

Chemotherapy Side Effects

Chemotherapy affects rapidly dividing cells, including some healthy cells. Therefore, side effects can occur, although their severity varies from person to person and depends on the medicines used.

Common chemotherapy side effects include:

• Fatigue: A frequent side effect that may result from treatment, anaemia, reduced nutrition, or the underlying cancer.
• Nausea and vomiting: Some chemotherapy drugs can stimulate the body’s vomiting pathways. Antiemetic medicines are often prescribed to prevent or control these symptoms.
• Hair loss: Certain chemotherapy drugs can temporarily affect hair follicles, leading to partial or complete hair loss.
• Low blood cell counts: Chemotherapy can reduce white blood cells, red blood cells, and platelets, potentially increasing the risk of infection, anaemia, or bleeding.
• Mouth sores: Inflammation of the mouth and throat may make eating or drinking uncomfortable.
• Changes in appetite and taste: Patients may experience reduced appetite or altered taste and smell.
• Diarrhoea or constipation: Changes in bowel habits may occur depending on the chemotherapy regimen.
• Peripheral neuropathy: Some drugs can cause numbness, tingling, burning, or weakness, particularly in the hands and feet.

Most side effects are manageable with appropriate supportive care. Patients should promptly inform their oncology team about fever, unusual bleeding, severe vomiting, breathing difficulty, or other concerning symptoms during treatment.
