Abstract:
Targeted therapies that act via unique molecular pathways and interfere with cancer cell growth and tumor progression have dramatically changed the cancer treatment paradigm. However, although, ideally, these therapies intend to target only cancer cells, they do often affect nonmalignant tissue. Numerous renal side effects have been reported to date. This article will review clinical presentation, presumed pathophysiology, and treatment of kidney side effects of targeted therapies. Feasibility of the continuation of cancer therapy despite renal toxicity will also be addressed.
Insights
Targeted cancer therapies can harm kidneys, causing renal side effects. This review covers kidney issues from targeted treatments, their management, and continuing cancer therapy amid renal toxicity.
Area of Science:
- Oncology
- Nephrology
- Pharmacology
Background:
- Targeted therapies represent a paradigm shift in cancer treatment by interfering with cancer cell growth.
- While designed for cancer cells, these therapies can affect nonmalignant tissues, leading to various side effects.
- Renal toxicity is a significant concern associated with numerous targeted cancer therapies.
Purpose of the Study:
- To review the clinical presentation of kidney side effects caused by targeted therapies.
- To elucidate the presumed pathophysiology underlying these renal toxicities.
- To discuss treatment strategies and the feasibility of continuing cancer therapy despite renal toxicity.
Main Methods:
- Literature review of clinical studies and case reports on targeted therapies and renal side effects.
- Analysis of reported mechanisms of action for targeted agents and their renal impact.
- Synthesis of current treatment guidelines and management approaches for nephrotoxicity.
Main Results:
- Targeted therapies can manifest a spectrum of renal pathologies, including acute kidney injury, chronic kidney disease, and electrolyte disturbances.
- Specific molecular pathways targeted by cancer drugs are linked to distinct patterns of renal damage.
- Management strategies often involve dose modification, supportive care, and, in some cases, discontinuation of the offending agent.
Conclusions:
- Understanding the diverse renal side effects of targeted therapies is crucial for oncologists and nephrologists.
- Early recognition and appropriate management can mitigate kidney damage and allow for cancer treatment continuation.
- Further research is needed to develop more kidney-sparing targeted agents and refine management protocols.

Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
