High-risk Cutaneous Squamous Cell Carcinoma (high-risk + cutaneous_squamous_cell_carcinoma)
Selected AbstractsSurgical Monotherapy Versus Surgery Plus Adjuvant Radiotherapy in High-Risk Cutaneous Squamous Cell Carcinoma: A Systematic Review of OutcomesDERMATOLOGIC SURGERY, Issue 4 2009ANOKHI 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] High-Risk Cutaneous Squamous Cell Carcinoma without Palpable Lymphadenopathy: Is There a Therapeutic Role for Elective Neck Dissection?DERMATOLOGIC SURGERY, Issue 4 2007JUAN-CARLOS MARTINEZ MD PURPOSE The beneficial role of elective neck dissection (END) in the management of high-risk cutaneous squamous cell carcinoma (CSCC) of the head and neck remains unproven. Some surgical specialists suggest that END may be beneficial for patients with clinically node-negative (N0) high-risk CSCC, but there are few data to support this claim. We reviewed the available literature regarding the use of END in the management of both CSCC and head and neck SCC (HNSCC). METHODOLOGY The available medical literature pertaining to END in both CSCC and HNSCC was reviewed using PubMed and Ovid Medline searches. RESULTS Many surgical specialists recommend that END be routinely performed in patients with N0 HNSCC when the risk of occult metastases is estimated to exceed 20%; however, patients who undergo END have no proven survival benefit over those who are initially staged as N0 and undergo therapeutic neck dissection (TND) after the development of apparent regional disease. There is a lack of data regarding the proper management of regional nodal basins in patients with N0 CSCC. In the absence of evidence-based data, the cutaneous surgeon must rely on clinical judgment to guide the management of patients with N0 high-risk CSCC of the head and neck. CONCLUSIONS Appropriate work-up for occult nodal disease may occasionally be warranted in patients with high-risk CSCC. END may play a role in only a very limited number of patients with high-risk CSCC.

Veness MMed (Clin Epi) Abstract Nonmelanoma skin cancers occur at an epidemic rate in Australia and are increasing in incidence worldwide. In most patients, local treatment is curative. However, a subset of patients will be diagnosed with a high-risk cutaneous squamous cell carcinoma (SCC) and are defined as patients at increased risk of developing metastases to regional lymph nodes. Patients with high-risk SCC may be identified based on primary lesion and patient factors. Most cutaneous SCC arises on the sun-exposed head and neck. The parotid and upper cervical nodes are common sites for the development of metastases arising from ear, anterior scalp, temple/forehead, or scalp SCC. The mortality and morbidity associated with high-risk cutaneous SCC is usually a consequence of uncontrolled metastatic nodal disease and, to a lesser extent, distant metastases. Patients with operable nodal disease have traditionally been recommended for surgery. The efficacy of adjuvant radiotherapy has previously been questioned based on weak evidence in the early literature. Recent evidence from larger studies has, however, strengthened the case for adjuvant radiotherapy as a means to improve locoregional control and survival. Despite this, many patients still experience relapse and die. Research aimed at improving outcome such as a randomized trial incorporating the addition of chemotherapy to adjuvant radiotherapy is currently in progress in Australia and New Zealand. Ongoing research also includes the development of a proposed new staging system and investigating the role of molecular factors such as the epidermal growth factor receptor. © 2007 Wiley Periodicals, Inc. Head Neck, 2007 [source] Treatment recommendations in patients diagnosed with high-risk cutaneous squamous cell carcinomaJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 5 2005MJ Veness Summary Non-melanoma cutaneous cancers occur at an epidemic rate in Australia. With an ageing population, more Australians will develop these cancers and at an increasing rate. In the majority of cases local treatment is highly curative. However, a subset of the population will be diagnosed with a high-risk cutaneous squamous cell carcinoma. These can be defined as patients at risk of having subclinical metastases to regional lymph nodes based on unfavourable primary lesion features (including inadequately excised and recurrent lesions), patients with metastatic squamous cell carcinoma to regional lymph nodes, and squamous cell carcinoma in immunosuppressed patients. The mortality and morbidity associated with high-risk cutaneous squamous cell carcinoma is usually as a consequence of uncontrolled metastatic nodal disease and, to a lesser extent, distant metastases. Radiotherapy has an essential role in treating these patients and in many cases the addition of adjuvant radiotherapy may be life saving. It is therefore important that all clinicians treating skin cancers have an understanding and awareness of the optimal approach to these patients. The aim of this article is to present treatment recommendations based on an overview of the current published literature. [source] | ||||||||||
