Optic and otic side effects of molecular targeted therapies

Abstract

Insights

Molecular targeted therapies can cause unique optic and otic toxicities that impact patient quality of life. Early recognition and management of these side effects are crucial for maintaining well-being.

Area of Science:

  • Oncology
  • Ophthalmology
  • Otolaryngology

Background:

  • Molecular targeted therapies offer novel treatment strategies in oncology.
  • While often having fewer systemic side effects than traditional chemotherapy, targeted therapies present unique toxicity profiles.
  • Ocular and auditory toxicities are emerging concerns with these advanced treatments.

Purpose of the Study:

  • To review the optic and otic toxicities associated with molecular targeted therapies.
  • To describe the presentation, grading, and management strategies for these specific side effects.

Main Methods:

  • Literature search conducted using PubMed, CINAHL, and the Cochrane Library.
  • Relevant nursing textbooks were also consulted for comprehensive information.

Main Results:

  • Targeted therapies, while distinct from chemotherapy, can induce specific ocular and auditory toxicities.
  • These toxicities, though not typically life-threatening, significantly affect patient quality of life.

Conclusions:

  • Optic and otic toxicities are recognized side effects of various targeted therapies.
  • Implementing baseline and periodic assessments for ocular and auditory health is vital for early detection.
  • Prompt recognition and intervention are essential for preserving patients' quality of life during treatment.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...
