Squamous cell carcinoma in situ (SCCin), a common form of skin cancer, has long posed challenges for patients and clinicians alike. While surgical interventions remain a standard treatment, a recent study highlights the efficacy of topical 5-fluorouracil (5-FU) cream as a nonsurgical alternative, particularly for smaller lesions and prolonged treatment durations.The study, published in the Journal of the American Academy of Dermatology, analyzed 149 cases of SCCin treated with 5% 5-FU cream. The findings revealed a complete clinical response (CCR) rate of 87.9%, underscoring the potential of this treatment for patients seeking noninvasive options.
Key findings: Treatment Duration and Tumor Size Matter
The research, led by christine P. Lin, Nour Kibbi, and Tarek Bandali, identified two critical factors influencing treatment success: treatment duration and tumor size.
- Longer Treatment Durations Yield Better Results: Patients who underwent treatment for 4 weeks or longer achieved a CCR rate of 93.2%, compared to 57.1% for those treated for less than 2 weeks.Shorter durations significantly increased the odds of treatment failure (OR, 0.26; P = .007).
- Smaller Tumors Respond More Effectively: Tumors less than 2 centimeters in diameter had an 88.9% CCR rate, while larger tumors (≥2 cm) showed a lower response rate of 60.0% (P = .051).
Thes findings suggest that prolonged application of 5-FU cream and early intervention for smaller lesions are key to maximizing treatment success.
A Viable option for Immunosuppressed Patients
One of the most promising aspects of this study is its implications for immunosuppressed patients, who often face higher risks of skin cancer. Among the 149 cases analyzed,33.6% (50/149) arose in the context of immunosuppression. Notably, neither immunosuppression nor anatomical location significantly impacted treatment outcomes, making 5-FU a versatile option for this vulnerable population.“these findings demonstrate that topical 5-fluorouracil is an effective nonsurgical treatment, particularly for smaller lesions and when administered for prolonged periods,” the authors noted.
Breaking Down the Data
To better understand the study’s results, here’s a summary of key findings:
| Factor | CCR Rate | Odds Ratio (OR) | P-Value |
|————————–|———————–|———————|————-|
| Treatment Duration ≥4 weeks | 93.2% | 0.26 | 0.007 |
| Tumor Size <2 cm | 88.9% | 2.40 | 0.037 |
| Immunosuppression | No significant impact | N/A | N/A |
Why This Matters
For patients with SCCin, topical 5-FU offers a noninvasive, cost-effective alternative to surgery. Its effectiveness in treating smaller lesions and its applicability to immunosuppressed individuals make it a valuable tool in dermatological care.
However, the study also highlights the importance of adhering to longer treatment durations to minimize the risk of treatment failure. Clinicians should consider these factors when prescribing 5-FU cream to ensure optimal outcomes.
Looking Ahead
As the medical community continues to explore nonsurgical treatments for skin cancer, this study provides compelling evidence for the use of topical 5-FU. future research could further refine treatment protocols, potentially expanding its use to other forms of skin cancer.

Interview with Dr. Christine P. Lin: Expert Insights on Topical 5-FU
today, we are joined by Dr. Christine P. Lin, a leading dermatologist and one of the principal researchers behind this groundbreaking study. Dr. Lin is here to share her insights on the efficacy of topical 5-FU as a nonsurgical treatment for SCCin, its implications for immunosuppressed patients, and the key factors influencing treatment success.
The Efficacy of Topical 5-FU: A Noninvasive Breakthrough
Senior Editor: Dr. Lin, let’s start with the big picture. What does this study tell us about the potential of topical 5-FU as a nonsurgical treatment for SCCin?
Dr. Christine P.Lin: This study is a significant step forward in demonstrating that topical 5-FU can be an highly effective noninvasive option for treating SCCin. We observed a complete clinical response (CCR) rate of 87.9% across 149 cases, which is quite promising. What’s particularly exciting is that this treatment offers a viable alternative to surgery, especially for patients who may not be candidates for customary surgical interventions due to underlying health conditions or personal preferences.
Treatment Duration and Tumor Size: Critical factors for Success
Senior Editor: The study identifies two critical factors influencing treatment success—treatment duration and tumor size. Can you elaborate on these findings?
Dr. Christine P. Lin: Absolutely. We found that longer treatment durations—specifically, 4 weeks or longer—yielded significantly better results, with a CCR rate of 93.2%,compared to 57.1% for shorter-term treatments. This underscores the importance of adhering to prolonged submission for maximizing outcomes.
Similarly, smaller tumors—those less than 2 centimeters in diameter—responded more effectively, achieving a CCR rate of 88.9% versus 60.0% for larger tumors. These findings suggest that early intervention and targeted application of 5-FU cream are key to treatment success.
Topical 5-FU: A Viable Option for Immunosuppressed Patients
Senior Editor: One of the most promising aspects of this study is its implications for immunosuppressed patients. Can you share more about this?
Dr. Christine P. Lin: Immunosuppressed patients, such as those with organ transplants or chronic autoimmune conditions, often face higher risks of skin cancer and may struggle with traditional treatments. In our study, 33.6% of the cases analyzed arose in the context of immunosuppression.Importantly, neither immunosuppression nor anatomical location significantly impacted treatment outcomes, making topical 5-FU a versatile and effective option for this vulnerable population.
Breaking Down the Data: What Clinicians Should Know
