Understanding Cancer Control: Treatment Options and Approaches

Multimodal Cancer Control Strategies

Cancer control aims to eradicate, contain, or palliate malignancy. Treatment is tailored to type, stage, molecular profile, and patient factors.

Primary Modalities

1. Surgery

Curative resection of localized tumor with negative margins. Minimally invasive (laparoscopic/robotic) when appropriate.

2. Radiotherapy

High-energy ionizing radiation (photons, protons, electrons). External beam (EBRT) or internal (brachytherapy). Techniques: IMRT, VMAT, SBRT/SRS for precision.

3. Systemic Therapy

• Chemotherapy: Cytotoxic agents targeting rapidly dividing cells. Adjuvant, neoadjuvant, or palliative.
• Targeted Therapy: Inhibits specific oncogenic drivers (EGFR, ALK, HER2, BRAF, VEGF, etc.). Requires biomarker testing.
• Immunotherapy: Checkpoint inhibitors (PD-1/PD-L1, CTLA-4), CAR-T, cancer vaccines, bispecific antibodies. Activates host immune response.
• Hormone Therapy: For hormone-dependent cancers (breast ER/PR+, prostate). SERMs, AIs, GnRH agonists, AR antagonists.

4. Palliative & Supportive Care

Integrated early: pain/symptom management, psychosocial support, advance care planning, nutrition, hospice when appropriate. Improves quality of life and may extend survival.

Multidisciplinary Decision-Making

Tumor boards (medical/surgical/radiation oncology, pathology, radiology, genetics, nursing) formulate individualized plans. Clinical trials should be considered at each decision point.
