Abstract:
Actinic keratosis (AK), located on sun-exposed areas of the skin, is an increasing global health burden. Multiple ablative and topical treatment options are available to manage this disease; however, topical treatment options are receiving significant interest because AK is commonly associated with areas of substantial photodamage, and destructive modalities cannot effectively treat subclinical AK. Several topical therapies, including 0.5% and other 5-fluorouracil concentrations, photodynamic therapy, 3% diclofenac sodium gel, and imiquimod 5% cream, are indicated in the treatment of AK. This article will review key data on the efficacy and safety of several topical therapies in the treatment and management of AK. The review includes discussions of imiquimod 5% cream, approved in 2004 in the treatment of AK of the face or scalp. Whether administered as monotherapy or adjunctive therapy, topical therapies provide the opportunity to effectively manage AK and will likely emerge as an important tool for healthcare providers.
Insights
Topical treatments are gaining interest for managing actinic keratosis (AK), a growing skin condition. These therapies effectively treat subclinical AK and offer a valuable option for healthcare providers.
Area of Science:
- Dermatology
- Oncology
Background:
- Actinic keratosis (AK) presents a significant global health challenge, primarily affecting sun-exposed skin.
- Current management involves ablative and topical treatments, with a growing focus on topical options due to their ability to address subclinical lesions in photodamaged skin.
Purpose of the Study:
- To review the efficacy and safety data of various topical therapies for actinic keratosis.
- To highlight the role of topical treatments in managing AK, particularly in the context of photodamage.
Main Methods:
- Literature review of key data on topical treatments for AK.
- Discussion of specific agents including 5-fluorouracil, photodynamic therapy, diclofenac sodium gel, and imiquimod cream.
- Focus on imiquimod 5% cream, approved for facial and scalp AK.
Main Results:
- Topical therapies demonstrate efficacy in managing actinic keratosis.
- Imiquimod 5% cream is highlighted for its use in treating facial and scalp AK.
- Both monotherapy and adjunctive use of topical agents are effective.
Conclusions:
- Topical therapies are a promising and effective approach for managing actinic keratosis.
- These treatments are crucial for addressing subclinical disease and offer a valuable addition to the clinician's toolkit.

Cancer Therapies
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...
