Surgical Monotherapy Versus Surgery Plus Adjuvant Radiotherapy in High-Risk Cutaneous Squamous Cell Carcinoma: A Systematic Review of Outcomes

DERMATOLOGIC SURGERY, Issue 4 2009
ANOKHI Jambusaria-PAHLAJANI MD
BACKGROUND Adjuvant radiotherapy (ART) has been recommended for squamous cell carcinoma (SCC) with a high risk of recurrence, particularly perineurally invasive disease. The utility of ART is unknown. This study compares reported outcomes of high-risk SCC treated with surgical monotherapy (SM) with those of surgery plus ART (S+ART). METHODS The Medline database was searched for reports of high-risk SCC treated with SM or S+ART that reported outcomes of interest: local recurrence, regional or distant metastasis, or disease-specific death. RESULTS There were no controlled trials. Of the 2,449 cases of high-risk SCC included, 91 were treated with S+ART. Tumor stage and surgical margin status before ART were generally unreported. In 74 cases of perineural invasion (PNI), outcomes were statistically similar between SM and S+ART. In 943 high-risk SCC cases in which clear surgical margins were explicitly documented, risks of local recurrence, regional metastasis, distant metastasis, and disease-specific death were 5%, 5%, 1%, and 1%, respectively. CONCLUSIONS High cure rates are achieved in high-risk cutaneous SCC when clear surgical margins are obtained. Current data are insufficient to identify high-risk features in which ART may be beneficial. In cases of PNI, the extent of nerve involvement appears to affect outcomes, with involvement of larger nerves imparting a worse prognosis. [source]

background. The effectiveness of partial nail avulsion followed by matricectomy with carbon dioxide (CO2) laser for the treatment of ingrown great toenails remains unclear. objective. This study sought to determine the effectiveness of partial nail avulsion followed by matricectomy with sharpulse CO2 laser in the treatment of recurrent ingrown great toenails associated with granulation tissue. materials and methods. Fourteen patients with a total of 18 recurrent ingrown great toenails were randomly selected for participation in this study. Partial nail avulsions followed by matricectomy with sharpulse CO2 laser were performed on the involved nails. After at least 6 months, we evaluated the recurrence of ingrown toenails, regrowth of the nail spike, duration of post-treatment pain and post-treatment infection. results. Partial nail avulsion followed by matricectomy with sharpulse CO2 laser in the treatment of ingrown toenails resulted in a high cure rate, short postoperative pain duration and low risk of postoperative infection. conclusion. This method we advocate is convenient and effective for the treatment of recurrent ingrown great toenail associated with granulation tissue. [source]

Squamous cell carcinoma in situ of the skin: History, presentation, biology and treatment

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2004
John P Arlette
SUMMARY Squamous cell carcinoma in situ (SCCIS) of the skin is a problem commonly dealt with by dermatologists. The classic presentation, originally described by Bowen, is easily recognized, but presentation on some anatomical surfaces may be associated with less than typical features. Major aetiological factors for this disease are UV light, human papillomavirus infection and immunosuppression. The natural course of SCCIS is usually prolonged, with treatment being appropriate, but not urgent. The choice of therapy requires consideration of the location of the lesion, and a desire for a high cure rate without causing loss of form, function or cosmesis. The immunomodulatory agent imiquimod has offered a significant advance for the topical treatment of SCCIS. Our improved understanding of the underlying biology of SCCIS permits us to make rational choices of treatment. In the future we may be able to determine which of these lesions may progress to invasive disease, and help us select the most effective therapy. [source]

Hidradenitis Suppurativa: Importance of Early Treatment; Efficient Treatment with Electrosurgery

DERMATOLOGIC SURGERY, Issue 2 2008
A. BURHAN AKSAKAL MD
BACKGROUND Hidradenitis suppurativa is a challenging condition, both for the physicians and for the patients. Many surgical and medical approaches with different success rates have been undertaken. Early and appropriate intervention is a factor that significantly increases the success rate of the treatment of the disease. OBJECTIVE This study was conducted to evaluate the efficiency of electrosurgery treatment in early hidradenitis suppurativa. MATERIALS AND METHODS This study comprised 12 patients aged between 29 and 38 years (mean, 34 years) with a diagnosis of hidradenitis suppurativa Grade I (n=9) or Grade II (n=3). A surgical method consisted of excision of the areas with nodules and sinuses, up to the level of subcutaneous fat tissue, and leaving the surgical defect for secondary healing. RESULTS All patients completed the study. In 10 of 12 (83%) patients, 26 of 30 (86%) lesions, cure was observed in a mean of 16 days (range 15 to 21 days). Four lesions in 2 patients with Grade II became infected and required a short course of antibiotic therapy. CONCLUSION Electrosurgery will decrease the need for other systemic treatments, owing to its high cure rates. Our results showed that electrosurgery should be considered a top alternative in the treatment algorithm of hidradenitis suppurativa. [source]

Mohs Micrographic Surgery in the Treatment of Rare Aggressive Cutaneous Tumors: The Geisinger Experience

DERMATOLOGIC SURGERY, Issue 3 2007
CHADWICK JOHN THOMAS MD
BACKGROUND Mohs micrographic surgery (MMS) offers high cure rates and maximum tissue preservation in the treatment of more common cutaneous malignancies, but its effectiveness in rare aggressive tumors is poorly defined. OBJECTIVE Evaluate the effectiveness of MMS in the treatment of six rare aggressive cutaneous malignancies as seen by Mohs surgeons working at a referral center. METHODS Retrospective chart review of 26,000 cases treated with MMS at the Geisinger Medical Center Department of Dermatology during a 16-year period with the following diagnoses: poorly differentiated squamous cell carcinoma (PDSCC), dermatofibrosarcoma protuberans (DFSP), microcystic adnexal carcinoma (MAC), extramammary Paget's disease (EMPD), Merkel cell carcinoma (MCC), and sebaceous carcinoma (SEB CA). Patient demographic data, tumor measurements, treatment characteristics, and marginal recurrence rates were compiled and evaluated. RESULTS The mean numbers of cases identified per year for each tumor type were as follows: PDSCC, 6.19; DFSP, 2.44; MAC, 1.63; and EMPD, 0.63. For PDSCC, 85 cases were available for follow-up with a local recurrence rate of 6% at a mean follow-up time of 45 months. For DFSP, there were 35 cases with no local recurrence at a mean follow-up of 39 months. For MAC, there were 25 cases with a local recurrence rate of 12% at a mean follow-up of 39 months. For EMPD, there were 10 cases with no local recurrences at a mean follow-up of 34 months. CONCLUSIONS Collectively, our data on PDSCC, DFSP, MAC, and EMPD, combined with other studies in the literature, show that MMS is the most effective therapy for these rare aggressive cutaneous malignancies.

Mohs micrographic surgery for facial skin cancer

vuyk h.d. &lohuis p.j.f.m. (2001) Clin. Otolaryngol.26, 265,273 Mohs micrographic surgery for facial skin cancer Although it is well established that conventional treatment modalities generally result in high cure rates for non-melanoma skin cancer, it has been demonstrated over recent decades that the highest overall cure rates are achieved using Mohs micrographic surgery. The key to Mohs surgery is the excision and control of complete peripheral and deep resection margins in one plane, allowing orientation, mapping and re-excision of microscopic tumour extension. These extensions can be followed without sacrificing inappropriate amounts of normal tissue, yielding high cure rates and maximum preservation of tissue. These qualities make Mohs surgery an important and reliable treatment for skin cancer of the face, in particular when it concerns large, aggressive or recurrent carcinoma in cosmetic and functionally important areas. In an 8-year study period, 369 basal cell carcinomas (BCCs) and 56 squamous cell carcinomas (SCCs) of the face were treated in our department using Mohs surgery. With a follow-up ranging from 3 months to 99 months (mean 33 months), none of the BCCs recurred and only one (2%) of the SCCs recurred a few months postoperatively. These favourable cure rates using the modality of Mohs surgery are the reason for highlighting this technique in the current review. [source]
