Summary
Nearly half of nonmelanoma skin cancer (NMSC) patients develop a new NMSC within 5 years. Integrated skin cancer awareness, sun protection, and prophylactic strategies are crucial for long-term management.
Area of Science:
- Dermatology
- Cutaneous Oncology
- Oncology
Background:
- Nonmelanoma skin cancer (NMSC), including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), has a high recurrence rate, with nearly 50% of patients developing a new NMSC within five years.
- Effective management of NMSC requires ongoing surveillance and preventative measures beyond initial treatment.
- Tumor risk profiling is essential for determining appropriate treatment modalities and the involvement of specialized medical professionals.
Purpose of the Study:
- To outline a comprehensive approach to managing nonmelanoma skin cancer (NMSC).
- To differentiate treatment strategies based on NMSC risk profiles.
- To highlight the role of specialized dermatological care and advanced surgical techniques.
Main Methods:
- Review of current therapeutic strategies for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
- Classification of NMSCs based on risk factors to guide treatment selection.
- Evaluation of outpatient treatment options, including electrodesiccation and curettage (EDC), cryotherapy, and topical 5-fluorouracil for low-risk lesions.
- Assessment of surgical interventions like excision with histologic examination and Mohs micrographic surgery (MMS) for high-risk tumors.
Main Results:
- Superficial BCC and SCC can be effectively treated with superficial modalities like EDC and cryotherapy.
- Topical 5-fluorouracil is suitable for small, in situ lesions.
- Invasive, low-risk lesions may be managed with EDC or cryotherapy if specific criteria are met.
- High-risk NMSCs warrant treatment with excision or Mohs micrographic surgery (MMS).
- Mohs micrographic surgery (MMS) offers the highest cure rates, optimal margin control, and tissue conservation for NMSCs.
Conclusions:
- An integrated program encompassing skin cancer awareness, sun protection, and prophylactic measures is critical for patients with NMSC.
- Treatment decisions for NMSC should be guided by tumor risk stratification.
- While outpatient methods suffice for low-risk NMSCs, high-risk lesions necessitate specialized management, with Mohs micrographic surgery (MMS) being the gold standard for optimal outcomes.

01:12Renewal of Skin Epidermal Stem Cells
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
