About Lesson

Introduction:

Chemotherapy is a systemic treatment modality that uses drugs to destroy cancer cells or inhibit their growth and proliferation. It is a cornerstone of cancer treatment and is used alone or in combination with other modalities such as surgery, radiation therapy, targeted therapy, or immunotherapy. This session provides an overview of chemotherapy in cancer management.

Key Concepts:

  1. Mechanism of Action:

    • Chemotherapy drugs target rapidly dividing cells, including cancer cells, by interfering with their ability to divide and multiply. They may also affect normal cells with a high turnover rate, leading to side effects.
  2. Systemic Treatment:

    • Unlike localized treatments such as surgery or radiation therapy, chemotherapy is administered systemically, meaning it circulates throughout the body via the bloodstream to reach cancer cells wherever they may be located.
  3. Types of Chemotherapy Agents:

    • Chemotherapy drugs may be classified based on their mechanism of action, chemical structure, or specific targets within cancer cells. Common types include alkylating agents, antimetabolites, anthracyclines, taxanes, and platinum-based drugs.

Indications for Chemotherapy:

  1. Adjuvant Therapy:

    • Chemotherapy may be used as adjuvant therapy following primary treatment such as surgery to reduce the risk of cancer recurrence or metastasis.
  2. Neoadjuvant Therapy:

    • Neoadjuvant chemotherapy is administered before primary treatment, such as surgery or radiation therapy, to shrink tumors and facilitate their resection or to downstage locally advanced disease.
  3. Primary Treatment:

    • In some cases, chemotherapy may be the primary treatment modality for cancers that are not amenable to surgical resection or have metastasized to distant sites.

Administration of Chemotherapy:

  1. Routes of Administration:

    • Chemotherapy drugs can be administered via various routes, including oral tablets, intravenous (IV) infusion, intramuscular (IM) injection, subcutaneous (SC) injection, or intrathecal injection for central nervous system (CNS) cancers.
  2. Treatment Schedules:

    • Chemotherapy regimens may consist of single agents or combinations of drugs administered in cycles with rest periods to allow for recovery from side effects. Treatment schedules vary depending on the type and stage of cancer, as well as patient factors.

Side Effects and Management:

  1. Common Side Effects:

    • Chemotherapy can cause a range of side effects, including nausea and vomiting, fatigue, hair loss, bone marrow suppression (neutropenia, thrombocytopenia, anemia), mucositis, peripheral neuropathy, and organ toxicity.
  2. Supportive Care:

    • Supportive care measures such as antiemetics, growth factor support, transfusions, pain management, nutritional support, and psychosocial interventions are essential for managing chemotherapy-related side effects and improving quality of life.

Case Study:

Emma, a 55-year-old woman, was diagnosed with stage III breast cancer. She underwent neoadjuvant chemotherapy with a combination of anthracycline and taxane-based regimens to shrink her tumor before surgery. Despite experiencing side effects such as hair loss and fatigue, Emma’s treatment was successful, and she achieved a complete pathological response.

  2. Which route of administration is commonly used for intravenous chemotherapy infusion?

    • A. Oral tablets
    • B. Intramuscular injection
    • C. Intravenous infusion
    • D. Subcutaneous injection

    Answer: C. Intravenous infusion
