• Radiation Therapy: High-energy rays to destroy cancer cells.

The rationale behind adjuvant therapy lies in its ability to eradicate residual disease, thereby improving long-term outcomes and increasing the likelihood of cure. Adjuvant therapy ensures a comprehensive approach to cancer management.

Neoadjuvant Therapy: Shrinking Tumors Before Surgery

In contrast to adjuvant therapy, neoadjuvant therapy is administered before the primary treatment, such as surgery. The primary goal of neoadjuvant therapy is to reduce the size of the tumor, making surgical removal more feasible and potentially improving surgical outcomes.

Neoadjuvant treatments can include:

• Chemotherapy: To reduce the tumor burden.
• Radiation: To shrink the tumor locally.
• Targeted Agents: To inhibit specific cancer pathways.

The benefits of neoadjuvant therapy extend beyond tumor shrinkage. It can also allow for less extensive surgery, preserve organ function, and provide valuable information about the tumor's response to treatment, guiding subsequent therapeutic decisions.

Chemotherapy: Targeting Rapidly Dividing Cells

Chemotherapy is a systemic treatment that utilizes drugs to kill cancer cells throughout the body. The mechanism of action of chemotherapy is based on targeting rapidly dividing cells, which are characteristic of cancer.

Chemotherapy drugs are typically administered:

• Intravenously (through a vein).
• Orally (as pills or liquids).

There are numerous chemotherapy drugs, each with its own mechanism of action and side effect profile. Common examples include: taxanes, platinum-based drugs, and anthracyclines. Treatment regimens vary depending on the type and stage of cancer.

Radiation Therapy (Radiotherapy): Using High-Energy Rays to Target Cancer

Radiation therapy, also known as radiotherapy, uses high-energy rays or particles to damage the DNA of cancer cells, preventing them from growing and dividing. Radiation therapy can be delivered externally or internally.

Different types of radiation therapy include:

• External Beam Radiation Therapy: Radiation is delivered from a machine outside the body.
• Brachytherapy: Radioactive sources are placed directly inside the body near the tumor.

Radiation therapy is often used in combination with other treatments, such as surgery and chemotherapy, to improve cancer control.

Surgery (Surgical Resection): Physically Removing Cancerous Tissue

Surgery plays a critical role in the diagnosis and treatment of many types of cancer. It involves the physical removal of cancerous tissue from the body.

Surgical techniques used in cancer treatment include:

• Wide Local Excision: Removing the tumor along with a margin of surrounding healthy tissue.
• Lymph Node Dissection: Removing lymph nodes to check for cancer spread.
• Debulking Surgery: Removing as much of the tumor as possible when complete removal is not feasible.

Important surgical considerations include the stage of cancer, the location of the tumor, and the patient's overall health.

Hormone Therapy (Endocrine Therapy): Targeting Hormone-Sensitive Cancers

Hormone therapy, also known as endocrine therapy, is used to treat cancers that are sensitive to hormones, such as breast and prostate cancer.

The mechanisms of hormone therapy involve:

• Blocking hormone receptors on cancer cells, preventing hormones from stimulating their growth.
• Reducing hormone production in the body.

Hormone therapy is commonly used as adjuvant therapy after surgery to reduce the risk of recurrence in hormone-sensitive cancers.

Targeted Therapy: Precision Medicine Against Cancer

Targeted therapy represents a precision medicine approach to cancer treatment. It works by interfering with specific molecules or pathways that drive cancer growth and spread.

The process of identifying appropriate targets involves:

• Molecular testing of the tumor to identify genetic mutations or protein abnormalities.

Examples of targeted agents include:

• Tyrosine Kinase Inhibitors (TKIs): Block signaling pathways involved in cell growth and division.
• Monoclonal Antibodies: Target specific proteins on the surface of cancer cells.

Immunotherapy: Unleashing the Power of the Immune System

Immunotherapy harnesses the body's own immune system to fight cancer. It works by helping the immune system recognize and destroy cancer cells.

Different types of immunotherapy include:

• Checkpoint Inhibitors: Block proteins that prevent the immune system from attacking cancer cells.
• CAR-T Cell Therapy: Genetically engineered immune cells that target and kill cancer cells.

Patient selection criteria for immunotherapy often involve assessing the expression of certain biomarkers on cancer cells. Monitoring treatment response may involve imaging, blood tests, and assessment of immune-related side effects.

Key Concepts in Comprehensive Cancer Care
