Introduction to Chemotherapy and Cancer Care in Bangalore
Chemotherapy is one of the primary systemic cancer treatments used to destroy or control cancer cells throughout the body. Patients seeking chemotherapy in Bangalore have access to advanced treatment protocols using a wide range of anti-cancer medications designed to target rapidly dividing cells. Chemotherapy either destroys cancer cells or slows their growth and spread. This treatment is not typically considered a routine standalone treatment; it is an essential component of a comprehensive oncological treatment plan, utilised alongside other therapies for the best possible patient outcome, such as surgery, radiation and targeted therapy.
Types of Chemotherapy Used
Chemotherapy is classified by its purpose and when it is given in relation to other treatments.
Curative Chemotherapy
Curative chemotherapy is used to try to eliminate the cancer from the body. The treatments are designed to produce long-term remission or a cure and are generally used when the cancer is highly responsive to treatment.
Neoadjuvant Chemotherapy
Neoadjuvant chemotherapy is administered before the primary treatment, usually surgery, to shrink the tumour before surgery and improve surgical outcomes. It can be used on large tumours that are not easily operated on and for cancers such as breast, oesophagus, and rectal cancers. For example, if a woman has a big breast tumour, she may have chemotherapy before having a mastectomy to shrink it.
Adjuvant Chemotherapy
Adjuvant chemotherapy is given after the initial treatment, typically surgery, to kill any cancer cells that may have been left behind or to lower the risk of the cancer coming back. It’s often used to treat breast, colon and ovarian cancers. Chemotherapy might, for instance, be given after tumour surgery to treat the microscopic cancer cells that might remain.
Palliative Chemotherapy
Palliative chemotherapy can be used to treat symptoms in advanced stages when a cure might not be the priority. It enhances quality of life by reducing tumours that cause pain or pressure and prolonging life with greater comfort.
How Chemotherapy is Administered
The delivery method of Chemotherapy treatment in Bangalore largely depends on the type of drug and the patient’s diagnosis.
- Oral Chemotherapy
Certain modern anti-cancer chemotherapy medications are available as a pill or a capsule. These medications may be taken at home, but must be strictly adhered to and closely monitored by the oncology staff.
- Intravenous (IV) Chemotherapy
Most often, medication is injected directly into the vein. This enables the drugs to get into the bloodstream quickly and circulate throughout the body.
- Injectable Chemotherapy
Some treatments can be given as regular injections. These may be administered under the skin (subcutaneous) or in a muscle (intramuscular), depending on the drug’s pharmacological needs.
- Day-care and Hospital-based Delivery
Bangalore’s specialised centres often utilise day-care units, allowing patients to receive their infusions in a comfortable setting and return home the same day. Increased treatment intensity or treatments requiring close monitoring may necessitate a brief hospital stay.
Chemotherapy Drug Categories
Oncologists choose from multiple drug categories that work in various ways to attack cancer cells.
- Alkylating Agents: These affect the DNA of cancer cells by attaching an alkyl group to DNA, which prevents DNA replication or kills the cell. They are active against numerous cancers, including leukaemias, lymphomas, breast cancer, and lung cancer.
- Antimetabolites: These agents masquerade as normal cellular nutrients. These drugs mimic natural cellular substances and interfere with DNA and RNA production in cancer cells.
- Plant Alkaloids: These are drugs derived from plants that inhibit cell division and growth. They particularly target the parts of the cancer cell required for division into two.
- Anti-tumour Antibiotics: These drugs do not fight infection, as their name suggests, but they attack the DNA of cancer cells, preventing them from growing and dividing. Many of these drugs are derived from compounds produced by soil bacteria such as Streptomyces species.
- Corticosteroids: These are not the “killers” of the cancer cells, but they do have an important supportive role in reducing inflammation, suppressing the immune system if needed, and controlling nausea.
Cancers Treated with Chemotherapy
Chemotherapy is a very versatile weapon in the battle against many types of cancer:
- Breast Cancer: Chemotherapy is commonly used in breast cancer treatment either to destroy remaining cancer cells after surgery or to shrink tumours before surgery.
- Lung Cancer: Useful for both small cell and non-small cell.
- Blood Cancers: These are the most common cancers in which surgery is not an appropriate treatment (leukaemia and lymphoma).
- Gastrointestinal Cancers: Chemotherapy is used to treat gastrointestinal cancers, such as stomach cancer (gastric cancer), before surgery (neoadjuvant) for the purpose of shrinking tumours, or after surgery (adjuvant) to eradicate residual cancer cells.
- Other Cancers: These include gynaecology cancers, prostate and head and neck.
Chemotherapy Treatment Process
The process of undergoing chemotherapy is a multi-step procedure that needs to be followed in a specific order to be done safely and effectively.
- Pre-treatment Evaluation: Detailed blood tests, imaging (such as CT or PET scans), and physical examinations are performed to ensure the body is strong enough to tolerate the drugs.
- Treatment Planning: The oncologist plans a unique mix of drugs, deciding on how many cycles will be required depending on the stage of the cancer.
- Conducting Sessions: During the session, the nursing staff administers medications and checks vital signs.
- Monitoring: The team does regular checks from session to session to monitor the tumour’s response and how the patient’s organs are responding to the treatment.
Outcomes and Effectiveness of Chemotherapy
The effectiveness of chemotherapy is measured by its ability to control the disease and improve the patient’s prognosis.
- Tumour Control and Shrinkage: One of the primary goals of chemotherapy is to control tumour growth and prevent the spread of cancer. Treatment of many cancers has greatly improved the prognosis for many types of cancer. For palliative cases, it focuses on maintaining self-reliance and comfort.
- Individual Variation: One thing to consider is how an individual will respond to treatment, which depends on the cancer’s genetics, the stage at which it is diagnosed, and the patient’s health.
Side Effects of Chemotherapy
Chemotherapy affects rapidly growing cells, which may also affect healthy rapidly dividing cells such as those in the hair follicles, digestive tract, and bone marrow.
- Short-term Effects: Nausea is a common side effect, as is severe tiredness and temporary hair loss.
- Immunity Issues: The medications can reduce white blood cell counts, increasing the risk of infection.
- Gastrointestinal and Neurological: Changes in appetite, diarrhoea, or “chemo brain” (mild memory or concentration loss) may occur.
- Management: Modern oncology treatments are called “supportive care” and aim to minimise such effects through specialised drugs that control nausea and support immune function.
Chemotherapy Treatment Duration and Cycles
The timeline for chemotherapy is not a one-size-fits-all approach.
- Number of Cycles: A standard treatment plan may include 4–8 cycles, depending on the type of cancer.
- Duration: One cycle can last anywhere from 3 to 4 weeks. The medication may be administered once or multiple times over one week during a particular cycle.
- Total Timeline: The course of the treatment can take many months, depending upon how the cancer responds to therapy and the toxicity to the patient.
