Targeted Cancer Therapies

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 specific...

Cancer Therapies

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...

Background:

Quantum dots (QDs) are luminescent semiconductor nanocrystals with unique optical properties.
Their brightness, stability, and tunable emission spectra make them suitable for cancer diagnostics and therapeutics.

Purpose of the Study:

To review the applications of QDs in cancer therapy.
To discuss limitations and toxicity issues of QDs in clinical settings.

Main Methods:

Literature review of QD applications in oncology.
Exploration of QD roles in molecular targeting, lymph node mapping, drug delivery, and photodynamic therapy.
Discussion of multifunctional QD designs and personalized medicine.

Main Results:

Bioconjugated QDs can identify biomarkers for cancer diagnosis, treatment, and prognosis.
QDs aid in sentinel lymph node mapping and complete surgical resection.
Multifunctional QDs enable synchronous cancer diagnosis, targeting, and treatment.

Conclusions:

Quantum dots offer significant potential in advancing cancer care through improved diagnostics and targeted therapies.
Toxicity remains a critical challenge hindering the clinical translation of quantum dots.
