Past, present and future of targeted therapy in solid tumors

Area of Science:

• Oncology
• Molecular Biology
• Pharmacology

Background:

• Targeted therapies offer precise cancer treatment by inhibiting specific molecular targets on neoplastic cells.
• Current targeted drugs focus on cell-surface proteins, intracellular proteins, and growth factors.
• Many common cancers now have targeted therapy options, used alone or with chemotherapy.

Purpose of the Study:

• To review currently available targeted drugs for lung, breast, colorectal, and renal cell cancers.
• To summarize the identification and molecular characterization of cancer targets and pathways.
• To discuss emerging targeted strategies against interconnected pathways and novel molecular targets.

Main Methods:

• Literature review of targeted therapies in oncology.
• Analysis of molecular targets and signaling pathways in common cancers.
• Summary of clinical applications and future directions in targeted cancer treatment.

Main Results:

• Established targeted therapies exist for major cancers, often involving epidermal growth factor receptors (EGFR) and vascular endothelial growth factors (VEGF).
• These therapies target key intracellular pathways governing cancer cell proliferation.
• New strategies are under investigation to target multiple pathways simultaneously or novel molecular targets.

Conclusions:

• Targeted therapies represent a significant advancement in cancer treatment, with established options for common malignancies.
• Understanding molecular targets and pathways is crucial for developing effective cancer drugs.
• Future research focuses on combination therapies and novel targets for improved patient outcomes.
