Chemotherapy: Overview, Treatment Insights, and Market Trends

Introduction

Chemotherapy is a widely used cancer treatment that involves the administration of powerful drugs to kill or inhibit the growth of cancer cells. It is commonly employed to treat various types of cancers, either as a primary therapy or in combination with other treatments such as surgery, radiation, and immunotherapy. Chemotherapy can help shrink tumors, prevent metastasis, and alleviate cancer symptoms.

How Chemotherapy Works

Chemotherapy drugs target rapidly dividing cells, which is a characteristic of cancer. However, because some healthy cells also divide quickly (like those in hair follicles, bone marrow, and the digestive tract), chemotherapy can lead to side effects. The treatment can be:

• Curative: Aimed at completely eliminating cancer.

• Palliative: Used to relieve symptoms and improve quality of life.

• Adjuvant: Given after surgery to destroy remaining cancer cells.

• Neoadjuvant: Administered before surgery to shrink tumors.

Types of Chemotherapy Drugs

• Alkylating Agents: Damage DNA to prevent cancer cell replication (e.g., cyclophosphamide).

• Antimetabolites: Interfere with DNA and RNA growth (e.g., methotrexate, fluorouracil).

• Anti-Tumor Antibiotics: Inhibit cell growth by altering DNA (e.g., doxorubicin).

• Plant Alkaloids: Block cell division (e.g., vincristine, paclitaxel).

• Topoisomerase Inhibitors: Interfere with enzymes that help separate DNA strands.

Common Side Effects

• Fatigue

• Hair loss

• Nausea and vomiting

• Immune suppression

• Increased risk of infections

• Anemia and bleeding issues

Supportive care and advances in drug formulations are helping manage these side effects more effectively.
