Cancer Treatment Modalities Beyond Chemotherapy: Comprehensive Overview

Cancer treatment is multimodal. Selection depends on type, stage, molecular profile, patient factors.

Major Modalities

1. Surgery: Primary resection ± lymphadenectomy. Curative for localized solid tumors. Minimally invasive (laparoscopic/robotic) increasingly standard.
2. Radiation Therapy: External beam (IMRT, SBRT, proton) or brachytherapy. Neoadjuvant, adjuvant, definitive, or palliative. Precision reduces toxicity.
3. Hormone Therapy: For hormone-receptor+ cancers (breast: ER/PR; prostate: AR). SERMs, AIs, LHRH agonists, anti-androgens.
4. Targeted Therapy: Small molecules/antibodies against specific molecular drivers (EGFR, HER2, BCR-ABL, BRAF, ALK, PARP, CDK4/6). Biomarker-driven.
5. Immunotherapy: Immune checkpoint inhibitors (PD-1/PD-L1, CTLA-4), CAR-T, bispecifics, cancer vaccines. Harnesses host immunity.
6. Palliative Care: Symptom control, goals-of-care discussion, psychosocial support. Concurrent with curative intent; not end-of-life only.

Emerging/Adjunctive

• Antibody-drug conjugates (ADCs).
• Tumor treating fields (TTFields).
• Microbiome modulation.
• Clinical trials (phase I–III).
