Int J Clin Pract 2024; 2024:5525741. [PMID: 38410673 PMCID: PMC10896655 DOI: 10.1155/2024/5525741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 01/09/2024] [Accepted: 01/29/2024] [Indexed: 02/28/2024] Open
Abstract
Cutaneous squamous cell carcinomas (cSCC) are malignant tumours with excellent prognosis unless nodal metastases develop. The aim of our study is to determine the prognostic significance of the clinical stage of parotid gland metastases and the incidence of occult cervical lymph node involvement in cSCC of the head. Our retrospective analysis includes 39 patients with cSCC parotid gland metastases, 15 of whom had concurrent cervical node involvement. In 32 patients, the lymph nodes manifested at stage N3b. A total of 26 patients were treated with parotidectomy, 9 patients received radiotherapy alone, and 4 received symptomatic therapy. The surgical treatment included either total conservative (21 cases) or superficial parotidectomy (5 cases) and neck dissection (therapeutic neck dissections in 11 cases and elective in 14 cases). In all cases, surgery was performed with sufficient tumour-free resection margins. Adjuvant radiotherapy was administered postoperatively in 16 patients. Occult metastases were present in 21% of cases after an elective neck dissection, but not in any case in the deep lobe of the parotid gland. The five-year overall survival and recurrence-free interval were 52% and 55%, respectively. Patients with the cN3b stage and G3 histological grade tend to have a worse prognosis, but not at a statistically significant level. The prognosis was not worse in patients with concurrent parotid and cervical metastases compared to those with metastases limited to the parotid gland only. The addition of adjuvant irradiation, in comparison to a single modality surgical treatment, was the only statistically significant prognostic factor that reduced the risk of death from this diagnosis (p=0.013). The extent of parotidectomy (partial vs. total) had no impact on either the risk of recurrence or patient prognosis. The combination of surgery with irradiation provides the best results and should be applied to all patients who tolerate the treatment. A partial superficial parotidectomy should be sufficient, with a minimum risk of occult metastasis in the deep lobe. Conversely, the relatively high incidence of occult neck metastases indicates that patients could likely benefit from elective neck dissection.

Adv Radiat Oncol 2024; 9:101306. [PMID: 38260235 PMCID: PMC10801645 DOI: 10.1016/j.adro.2023.101306] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 06/25/2023] [Indexed: 01/24/2024] Open
Abstract
Purpose For patients without pathologic evidence of cervical disease after neck dissection for cutaneous squamous cell carcinoma involving the parotid region, inclusion of the ipsilateral cervical neck in the postparotidectomy radiation volume is routinely performed. We report our experience with selective avoidance of the ipsilateral neck for patients undergoing postoperative radiation to the parotid bed. Methods and Materials From January 2014 to December 2023, a total of 30 consecutive patients underwent postoperative radiation after parotidectomy for cutaneous squamous cell carcinoma involving the parotid area. All patients had previously had a neck dissection confirming pathologic N0 disease. Treatment was delivered using intensity modulated radiation therapy to a median dose of 60 Gy (range, 56-66 Gy). The radiation target volumes included the parotid bed only, with deliberate avoidance of the ipsilateral cervical neck. The median pathologic tumor size of the parotid tumor was 3.3 cm (range, 0.2-9.4 cm). Final pathologic evaluation showed positive microscopic margins in 8 patients (27%), perineural invasion in 17 patients (57%), and facial nerve involvement in 6 patients (20%). Results There were no isolated nodal failures. One patient developed an ipsilateral neck recurrence approximately 8 months after completion of radiation therapy. This occurred 2 months subsequent to the development of local recurrence. The 5-year actuarial rates of local (parotid) control, neck control, and overall survival were 87%, 97%, and 76%, respectively. Conclusions Omission of the ipsilateral neck from the parotid volume does not compromise disease control for pathologically N0 patients undergoing postoperative radiation for cutaneous squamous cell carcinoma involving the parotid region. Practical implications are discussed.

Abstract
Non-melanoma skin cancer of the head and neck (NMSCHN) is one of the most common malignancies worldwide, and its incidence is growing at a significant rate. It has been found to be aggressive in its spread and has the capacity to metastasize to regional lymph nodes. Cutaneous squamous cell carcinoma (cSCC) has a considerably high mortality rate. It has remarkable characteristics: diameter >2 cm, depth >5 mm, high recurrence, perineural invasion, and locoregional metastases. Aggressive cSCC lesions most commonly metastasize to the parotid gland. Also, immunocompromised patients have a higher risk of developing this aggressive cancer along with the worst prognostic outcomes. It is very important to discuss and assess the risk factors, prognostic factors, and outcomes of patients with cSCC, which will give clinicians future directives for making modifications to their treatment plans. The successful treatment of aggressive cSCC of the head and neck includes early detection and diagnosis, surgery alone or adjuvant chemotherapy, and radiotherapy as required. Multimodal therapy options should be considered by clinicians for better outcomes of aggressive cSCC of the head and neck.

Abstract
Primary and secondary malignant tumors can affect the parotid gland. The aim of this retrospective study was to evaluate the clinical features and prognosis of malignant epithelial tumors of the parotid gland. In particular, a comparison between primary and secondary cancer and survival analyses were performed. Eighteen patients with primary cancer and fifteen with intraparotid metastasis from cutaneous squamous cell carcinoma were included. A chart review was performed to collect clinical data (age, sex, smoking, alcohol consumption, tumor stage, type of surgical procedure, complications, recurrence and death). The majority of primary tumors were early (T1-2 N0, 83%) with mucoepidermoid carcinoma being the most common (33%). Secondary tumors were mostly staged P2 (53%) and N0 (67%). Subjects with secondary tumors were older than those with primary cancer. Post-operative permanent facial palsy was observed in 5 patients (17%) with primary cancer and 9 (60%) with secondary tumors (p = 0.010). Two-year overall survival for primary and secondary parotid cancer was 76.58% and 43.51%, respectively (p = 0.048), while 2-year disease-free survival was 76.05% and 38.50%, respectively (p = 0.152). In conclusion, secondary cancer of the parotid gland has worse survival than primary tumors. In the future, the implementation of multimodality treatment of intraparotid metastases is necessary to improve oncologic outcomes.

Abstract
Radiation therapy (RT) is an effective therapeutic option for small localized cutaneous squamous cell carcinoma (cSCC) among patients who are not eligible for or refuse surgery. RT also has a defined role as an adjuvant treatment in cases of adverse features that predispose to tumor recurrence after local excision. Since the development of cSCC is often a late consequence of chronic sun exposure, its occurrence is more common among elderly patients whose comorbidities may contraindicate surgical procedures. These could be impeded not only by frail medical conditions but also by technical issues. Indeed, an aggressive locoregional behavior of cSCC may culminate in unresectability due to widespread invasion of neighboring tissues. Moreover, cSCC could develop distant metastases. Both locally advanced and metastatic cSCCs carry a poor prognosis. In these scenarios, recent discoveries of tumor molecular targets are promoting the use of promising systemic therapies, especially immunotherapy, over RT. However, the results from using immunotherapy and, even more so, of chemotherapy are still not optimal. By contrast, advances in radiation delivery equipment can safely treat even large and complex-shaped cSCC targets in challenging body sites. In addition, RT could also have a role in metastatic cSCC settings by enhancing the effectiveness of concomitant immunotherapy. The aim of this review is to summarize and comment on the body of literature about the use of radiotherapy for operable and inoperable locally advanced cSCCs and for metastatic ones in an attempt to define its current and future role.

Abstract
BACKGROUND Regional metastasis of head and neck cutaneous squamous cell carcinoma (HNcSCC) can be seen in either parotid and/or cervical lymph nodes. The aim of this study was to assess whether there was a difference in prognosis between parotid and cervical nodal metastases. METHODS Patients with regional metastasis from HNcSCC were identified from an institutional database. Disease-specific (DSS) and overall survival (OS) were calculated using the Kaplan-Meier method and Cox proportional hazards models. RESULTS Five hundred and thirty-five patients were identified with median follow-up of 26.4 months (3-255 months). Two hundred and thirty-five patients had parotid metastasis, 96 patients had neck metastasis, and 204 patients had both. On multivariable analysis, any regional metastasis to the neck when compared to parotid alone conferred worse DSS (HR 1.8, p = 0.007) and OS (HR 1.3, p = 0.024). CONCLUSION Regional metastasis of HNcSCC to the neck confers worse outcomes compared to metastasis to the parotid alone.

Abstract
PURPOSE To provide evidence-based recommendations for practicing physicians and other healthcare providers on the management of salivary gland malignancy. METHODS ASCO convened an Expert Panel of medical oncology, surgical oncology, radiation oncology, neuroradiology, pathology, and patient advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2020. Outcomes of interest included survival, diagnostic accuracy, disease recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 293 relevant studies to inform the evidence base for this guideline. Six main clinical questions were addressed, which included subquestions on preoperative evaluations, surgical diagnostic and therapeutic procedures, appropriate radiotherapy techniques, the role of systemic therapy, and follow-up evaluations. RECOMMENDATIONS When possible, evidence-based recommendations were developed to address the diagnosis and appropriate preoperative evaluations for patients with a salivary gland malignancy, therapeutic procedures, and appropriate treatment options in various salivary gland histologies.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in humans and its incidence is rising. Although surgery is the treatment of choice for cSCC, postoperative adjuvant radiotherapy has an important role in local and locorregional disease control. In this review, we analyze the value of postoperative radiotherapy in the management of high-risk cSCC (in particular, cases with perineural invasion), cSCC with positive surgical margins, and locally advanced cSCC (with parotid gland and/or lymph node metastasis).

Abstract
Non-melanoma skin cancers (NMSCs) are the most common malignancy worldwide, of which 99% are basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs) of skin. NMSCs are generally considered a curable diseases, yet they currently pose an increasing global healthcare problem due to rising incidence. This has led to a shift in emphasis on prevention of NMSCs with development of various skin cancer prevention programs worldwide. This article aims to summarize the most recent changes and advances made in NMSC management with a focus on prevention, screening, diagnosis, and staging.

Abstract
AbstractBackground:Metastatic cutaneous squamous cell carcinoma is the most common parotid malignancy in Australasia. Prognostic indicators are not clearly defined and the extent of surgical resection required is controversial.Methods:A retrospective analysis was conducted of 63 patients who underwent surgery for metastatic cutaneous squamous cell carcinoma of the parotid gland at a tertiary hospital over a 10-year period.Results:The five-year overall survival rate was 53 per cent, the disease-specific survival rate was 78 per cent and the locoregional control rate was 72 per cent. Immunosuppression and no adjuvant radiotherapy were associated with a significant reduction in disease-specific survival. None of the factors analysed had a significant effect on locoregional control rates.Conclusion:More extensive surgery, including lateral temporal bone resection, may improve local control rates in cases of more advanced disease. The reduced survival of immunocompromised patients must be considered when planning their management.

Abstract
OBJECTIVE To investigate the rate of occult neck disease in patients with metastatic squamous cell carcinoma to the parotid gland following parotidectomy and neck dissection. METHODS A consecutive series of patients treated between 2000 and 2014 for metastatic squamous cell carcinoma to the parotid were analysed. Patients were included if they had no clinical or radiological evidence of neck disease. Pathology of parotidectomy and neck dissection specimens was reviewed. Other variables analysed included patient immune status, surgery type, complications, use of positron emission tomography scanning and treatment with radiotherapy. RESULTS Sixty-five patients had no clinical or radiological evidence of neck disease initially. Forty-six patients (70.8 per cent) underwent neck dissection. Occult neck disease was only found in 8 of the 46 patients (17.3 per cent). Occult neck disease was found more often in those with immunocompromise (5.7 vs 38.5 per cent, p = 0.003). Patients who were immunocompromised had a significantly worse disease-specific survival rate at five years (0 vs 92 per cent, p = 0.0001). CONCLUSION Occult neck disease was seen in 17.3 per cent of patients and immunosuppression was a significant predictor for this.

Abstract
BACKGROUND Given its metastatic potential and high incidence, cutaneous squamous cell carcinoma of the head and neck (SCCHN) has significant morbidity and mortality. METHODS We conducted a retrospective review of prospectively collected data for 113 consecutive patients with nodal metastatic cutaneous SCCHN treated surgically with curative intent in a regional center. Survival curves were generated by the Kaplan-Meier method. RESULTS Five-year overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) were 80%, 83%, and 75%, respectively. Twenty-six patients (23%) relapsed, with 92% of relapses occurring within 2 years of surgery. Immunosuppression (p = .008) and N classification (p = .043) predicted decreased DFS on univariate analysis. On multivariate analysis, only immunosuppression independently predicted DFS (p = .034). CONCLUSION This study validates the current N classification system, supports the adverse effect of immunosuppression, and suggests that intense follow-up for 2 years postsurgery is warranted. Survival at this regional center is comparable to that achieved at metropolitan tertiary cancer centers.

Abstract
INTRODUCTION Squamous cell carcinomas (SCC) of the ear are known for their aggressiveness. The aim of this study was to investigate factors of gravity while freeing the therapeutic requirements. PATIENTS AND METHODS This is a retrospective study of 28 patients (30 ears) operated for SCC. The characteristics of the lesion, the presence of metastasis, treatment modalities and histologic findings were collected. Local recurrences and metastasis are identified with a mean follow-up time of 37months (17-110months). RESULTS The lesion size was less than 2cm in 19 cases (63.3%) and greater than or equal to 2cm in 11 cases (36.7%). Macroscopic resection margins were 5, 7 or 10mm. The resections were histologically incomplete in 4 cases (13%) requiring further surgery. Six cases had local recurrence (20%): three with pulmonary or lymph node metastases (10%) and one death (3.3%). In these 6 cases of recurrence, the surgical margins were 6.3mm on average, the initial lesion measured always greater than 2cm (100%). Three quarters of incomplete resections have recurrent despite a surgical revision in healthy margin. CONCLUSION Our study confirms the data of literature, namely the pejorative character of a lesion greater than 2cm and incomplete resection. The HAS recommendations seem minimal regarding the ear. In case of injury by more than 2cm and with a proximal location on the ear pinna, only amputation of the ear allows satisfactory cancer control.

Abstract
Skin has the highest incidence and variety of tumors of all organs. Its structure is of great complexity, and every component has the potential to originate a skin neoplasm (SN). Because of its exposed nature, skin is vulnerable to carcinogenic stimuli such as UV radiation. Various entities can cause SN. Nonmelanotic skin cancers (NMSC) are the most common of all cancers, with over one million cases diagnosed annually in the US. Basal cell carcinoma (BCC) accounts for approximately 80% of all NMSC, most of the remaining 20% being squamous cell carcinoma (SCC). The skin of the head and neck is the most common site for tumors, accounting for more than 80% of all NMSC. BCC, SCC, and malignant melanomas (MM) represent 85-90% of all SN. Merkel cell tumors (MCC), lymphoepithelioma-like carcinomas of the skin (LELCS), dermato-fibro-sarcomas, leiomyosarkomas, and Kaposi-sarcomas are less frequent in the facial skin region and the external ear. Based on data from the German Federal Cancer Registry (2003/2004), 140,000 people in Germany were affected by SN (100,000 BCC, 22,000 SCC, 22,000 MM). This number increases considerably if malignant precursors, such as actinic keratosis, are included. Each year, the frequency of SN diagnosis rises by 3-7%. Among all known malignant tumors, MM exhibits the highest rate of increase in incidence. In the past, SN was primarily diagnosed in people aged 50 years or older. However, recently, the risk for developing SN has shifted, and younger people are also affected. Early diagnosis is significantly correlated with prognosis. Resection of SN creates defects that must be closed with local or microvascular flaps to avoid functional disturbing scar formation and deflection of the nose, eyelids, or lips. All therapeutic strategies for SN, the current standard for adjuvant and systemic treatment, and the management of the increasing number of patients under permanent blood thinner medication are described with regard to the treatment of SN.

Abstract
Objective Evaluate characteristics and risk factors for patients with advanced cutaneous squamous cell carcinoma (cSCC). Study Design Retrospective case series. Setting Tertiary care center. Patients and Methods Chart review of patients with cSCC undergoing a parotidectomy (2003-2012). Results Of 218 patients identified, 49% presented with a new primary lesion (n = 107) and 51% with a recurrence (n = 111). Parotid lymph nodes were positive in 52% of patients; 81% had a concurrent neck dissection, and 28% had cervical lymph node metastases. In 18% of patients, both parotid and cervical nodes were positive, while 44% were both parotid and cervical node negative; 33% had positive parotid and negative cervical nodes, and only 5% had negative parotid and positive cervical nodes. The overall 2- and 5-year survival rates were 0.71 and 0.58. Overall 5-year survival was lower for patients presenting with recurrent (0.49) versus new primary disease (0.69; P = .04). In addition, decreased overall 5-year survival rates were associated with cervical lymph node involvement (0.47 vs. 0.62; P = .01). There was no difference in overall survival when stratified by parotid lymph node involvement ( P = .85), margin status ( P = .67), perineural invasion ( P = .42), facial nerve sacrifice ( P = .92), or type of parotid operation performed ( P = .51). Conclusions In this study, cervical, but not parotid, lymph node involvement was associated with poor outcomes in patients with advanced cSCC requiring a parotidectomy. In patients without evidence of cervical or parotid lymph node involvement, a neck dissection may be spared, given there is a 5% chance of occult disease.

Abstract
AIM: To investigate the rate of occult lymph node disease in elective parotidectomy and neck dissection specimens in patients with advanced auricular cutaneous squamous cell carcinoma (cSCC).
METHODS: At a single institution, from 2000 to 2010, 17 patients with advanced auricular cSCC were considered high risk for occult regional parotid and/or neck nodal metastases and, thus, underwent an auriculectomy and elective regional lymphadenectomy (parotidectomy and/or neck dissection). Indications for elective regional lymphadenectomy were large tumor size, locally invasive tumors, post-surgical and post-radiation recurrence, and being an immunosuppressed patient. We determined the presence of microscopic disease in the regional (parotid and neck dissection) pathology specimens.
RESULTS: There were 17 advanced auricular cSCC patients analyzed for this study. Fifteen (88%) patients were men. The average age was 69 (range: 33 to 86). Ten (59%) patients presented with post-surgical recurrence. Five (29%) patients presented with post-radiation recurrence. Four (24%) patients presented with both post-surgical and post-radiation recurrence. Four (24%) patients were immunosuppressed (2 (12%) were liver transplant patients, 2 (12%) were chronic lymphocytic leukemia patients, and 1 (6%) was both). The subsite distribution of cSCC included helix (3, 18%), antihelix (2, 12%), conchal bowl (7, 41%), tragus (2, 12%), and postauricular sulcus (3, 18%). Four (24%) patients presented with multifocal auricular cSCC. No patients had bilateral disease. All patients were confirmed to have cSCC on final pathology. The tumors were well (5, 29%), moderately (10, 59%), and poorly (2, 12%) differentiated SCC. The average size of the cSCC tumor was 2.9 cm (range: 1.7 to 7 cm). Twelve (70%) tumors were greater than 2 cm. Six (35%) patients underwent partial auriculectomy. Eleven (65%) patients underwent total auriculectomy. Eight (47%) patients underwent elective parotidectomy and elective neck dissections; 3 (18%) underwent only elective parotidectomy; 3 (18%) underwent only an elective neck dissection; 2 (12%) underwent an elective parotidectomy and therapeutic neck dissection; and 1 (6%) underwent a therapeutic parotidectomy and an elective neck dissection. None of the elective parotidectomy or neck dissection specimens were found to contain any malignant disease. All therapeutic parotidectomy and neck dissection specimens contained metastatic SCC. Fourteen (82%) underwent parotidectomy. Of these, 10 (71%) underwent superficial parotidectomy whereas 4 (29%) underwent total parotidectomy. Fourteen (82%) underwent neck dissections [levels II/Va (1, 7%), levels II/III/Va (2, 14%), levels I/II/III/Va (2, 14%), and complete levels I-V (9, 64%)]. Three (18%) underwent concurrent temporal bone resections for tumor extension from the auricle. The average follow-up for our patients was 44 mo (range: 4 to 123 mo). At the time of the review, 6 (35%) patients were alive and 11 (65%) had passed away.
CONCLUSION: This study suggests that, in patients with advanced auricular cutaneous SCC, elective regional lymphadenectomy is not necessary. However, furtherprospective studies are necessary to assess the necessity.

Abstract
Background Nodal metastasis from cutaneous SCC carries a high morbidity and mortality. Limited direct evidence is available as to the impact of radiotherapy on the outcome of patients with metastatic axillary SCC. The purpose of this study was to report on the outcomes of patients with metastatic cutaneous SCC to the axilla treated with radiotherapy. Methods A retrospective review of patients treated with radiotherapy between 1993 and 2010 for metastatic cutaneous SCC to the axilla was undertaken at St George Hospital, Sydney. Results Radiotherapy was administered to 36 patients, 30 with curative intent (4 definitive, 26 adjuvant) and 6 with palliative intent, 27/36 (75%) were male, 22/36 (61%) had a previous diagnosis of cutaneous SCC, and 1/36 (3%) was immunosuppressed. Mean age was 74.6 years. Mean radiotherapy dose (BEDGy10) was 61Gy10 (range 39-85 Gy10), 20/36 (56%) patients experienced recurrence, including 16 local failures and 4 isolated distant failures. Median survival for the curative and palliative groups was 3 years and 1 month, respectively. Relapse free survival (n = 36) at 2 and 5 years was 46% and 35%, respectively (curative 52% and 39%). Only 1 failure achieved complete salvage. Conclusion Despite current best practice (surgery and radiotherapy), the predominant pattern of failure in these patients with metastatic axillary cSCC was locoregional. The difficulty in successfully salvaging patients after locoregional nodal relapse suggests a need for treatment intensification.

Abstract
Background Cutaneous squamous cell carcinoma (cSCC) comprises 20% of all skin cancer of the head and neck. A minority will metastasize to regional parotid lymph nodes. This study evaluates the St Vincent’s Hospital, Sydney experience between 1996 and 2006. Methods A retrospective review was performed of patients who were evaluated in our multidisciplinary head and neck clinic with metastatic cSCC to parotid, and all treatment and pathologic details were reviewed. Statistical analysis, including univariate and multivariate analyses, were performed using Cox proportional hazards regression mode, overall and disease-specific survival were estimated by the Kaplan-Meier method. Results Sixty-seven patients were identified. Some 90 % were male, and with a mean age of 72.8 years. One died on the first postoperative day. The remaining 66 patients received radiotherapy. For these 66 patients, the two-year and five-year overall survival rate was 0.83 and 0.72, respectively. The two-year and five-year disease-free survival rate was 0.91 and 0.83 respectively. Overall survival was only significantly correlated to the extent of parotidectomy (superficial versus total; P = 0.0256). Margin status was available in 59 patients. The only parameter that significantly correlated with disease-free survival was margin status (close/negative versus positive P = 0.0348). Other parameters of immune suppression, perineural invasion, extra capsular extension, degree of tumour differentiation, number of positive nodes, extent of neck dissection and radiotherapy dosage delivered did not confer prognostic significance. Conclusions This study confirmed the association of adverse prognostic implication of positive margins on disease-free survival. Immune compromise was not a significant factor in this small group. Further studies are warranted in this population.

Abstract
BACKGROUND The purpose of this study was to compare the outcome of surgery against surgery plus radiotherapy in patients with metastatic cutaneous head and neck squamous cell carcinoma (HNSCC) to cervical nodes. METHODS We conducted a 28-year retrospective analysis of 122 patients whom were treated for metastatic cutaneous HNSCC involving the cervical nodes (levels I-V). RESULTS After surgery alone, 11 patients (55%) developed recurrence compared with 23 patients (23%) after surgery plus radiotherapy. On multivariate analysis, the following variables were significantly associated with disease-free survival (DFS): immunosuppression (p = .002), treatment modality (p < .001), extracapsular spread (p = .009), and pathological nodal stage (p = .04). Patients undergoing surgery plus radiotherapy had a significantly better 5-year DFS (74% vs 34%; p = .001) and 5-year overall survival (OS; 66% vs 27%; p = .003) compared with surgery alone. CONCLUSION In patients with metastatic cutaneous HNSCC involving cervical nodes, survival was significantly improved with the addition of radiotherapy.

Abstract
BACKGROUND We aimed to analyze the distribution of regional nodal metastases according to primary tumor location in patients with cutaneous squamous cell carcinoma of the head and neck (SCCHN). METHODS Analysis of 295 neck dissections performed for patients with clinically evident regional metastases from cutaneous SCCHN between 1987 and 2009. RESULTS Level I involvement in the absence of level II or III only occurred in patients with facial primaries. In patients with clear nodes in level II-III, the risk of level IV-V involvement was 0.0% for external ear primaries, 2.7% for face and anterior scalp, and 15.8% for posterior scalp and neck. CONCLUSION In patients undergoing parotidectomy for metastatic cutaneous SCCHN with a clinically negative neck, the results of this study support selective neck dissection including level I-III for facial primaries, level II-III for anterior scalp and external ear primaries, and levels II-V for posterior scalp and neck primaries.

The study involved a retrospective chart review from 1999 to 2008 of patients presenting with metastatic CSCC to the parotid at the Princess Alexandra Hospital, Brisbane, Australia. Results. Eighty-one patients with metastatic parotid disease were identified. A total of 51 (63%) patients had no clinical or radiological evidence of cervical nodal disease. Forty-five patients (88%) were male, median age was 69 (range, 42-91) years, and the median follow-up was 16 (interquartile range, 9-44) months. Thirty-four of these patients underwent a parotidectomy and neck dissection with/without postoperative radiotherapy (RT). Occult pathological cervical nodal disease was found in 5 (14.7%) patients. Of those who received a neck dissection, 3 patients relapsed in the parotid, 1 in the neck alone, and 1 distantly. Conclusion. This series has shown that the rate of pathologically involved neck nodes in patients with metastatic CSCC to the parotid in the clinically node negative neck is low. Given many of these patients warrant postoperative RT to the parotid bed, an elective neck dissection may not be warranted as the parotid and neck may be treated in continuity with RT.

Abstract
Non-Melanoma skin cancer (NMSC) is the most commonly encountered malignancy in almost every area of practice, but the cases that present to an Otolaryngology practice will be advanced in nature. The major subtypes of NMSC include basal cell carcinoma, squamous cell carcinoma, dermatofibrosarcoma protuberans, merkel cell carcinoma, and adnexal malignancies. In this review, we present the epidemiology, histology, clinical presentation and management of these major subtypes. Further, we present background on multimodality treatment for NMSC lesions that have become metastatic from their primary site and an introduction to the behavior and treatment of NMSC lesions in patients who have received organ transplants. Understanding the clinical behavior of advanced NMSC is essential knowledge for a general Otolaryngologist.

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.

Abstract
BACKGROUND The aim of the study was the characterization of patients with metastatic cutaneous squamous cell carcinoma involving the parotid gland. PATIENTS AND METHODS The clinical, radiological and pathological tumor data of 16 patients with parotid metastasis of a previously treated squamous cell carcinoma of the skin were analyzed retrospectively. RESULTS Patients over 70 years of age with a primary skin cancer of at least 1.5 centimeter in diameter were defined as the high risk group for development of regional metastasis involving the parotid gland. The time interval between therapy of the skin cancer and detection of the metastatic involvement of the parotid gland was 9.8 (2-24) months on average. The average maximal diameter of the parotid metastasis was 3.2 (1.5-4.9) centimeter at diagnosis. Metastatic infiltration of cervical lymph nodes could be shown in 9 patients and in 2 patients pulmonary metastases were detected. The average survival after parotid metastasis was 11.7 (3-31) months. CONCLUSION The early diagnosis and therapy of locoregional metastasis from cutaneous squamous cell carcinoma of the scalp have a high prognostic value. High-risk patients with cutaneous squamous cell carcinoma should be followed up sonographically in narrow intervals for detection of parotid and cervical lymph node metastasis.

Abstract
Management of tumors of the salivary glands requires a detailed understanding of the anatomy and pathologic processes affecting these glands. Salivary glands give rise to benign and malignant neoplasms and are affected by a variety of systemic diseases. CT remains the most common primary imaging study; magnetic resonance imaging and ultrasound have also been explored. Fine-needle aspiration as part of the diagnostic evaluation remains controversial due to varying sensitivities and specificities. Surgical extirpation is the primary modality for management of tumors of the salivary glands. Parotid surgery carries a potentially high morbidity with possible unsightly scarring and facial nerve damage. Nontraditional surgical approaches and instrumentation, as well as facial nerve monitoring, can decrease the morbidity of a parotidectomy. In specific instances, malignant salivary gland tumors warrant cervical lymphadenectomy. Adjuvant therapy is primarily accomplished with radiation. Chemotherapy continues to play a palliative role in salivary gland malignancies; however, newer trials are investigating the therapeutic role of chemotherapy.

Abstract
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.

Abstract
BACKGROUND Among patients with cutaneous squamous cell carcinoma (SCC) of the head and neck, recent studies have shown that those with involvement of the parotid gland also have a high incidence of neck node involvement. Treatment of the neck by either surgery or radiotherapy is therefore recommended among patients with parotid SCC, even if clinical examination is negative. The aim of this study was first to analyze patterns of metastatic spread in the parotid and cervical lymph nodes and then to correlate the pattern of involved nodes with the primary cutaneous site in order to guide the appropriate extent of surgery, should neck dissection be used to treat the neck in patients with parotid SCC. METHODS A cohort of 209 patients with cutaneous SCC of the head and neck and clinically evident regional metastatic disease was reviewed retrospectively from 3 Australian institutions. The distribution of involved nodes was obtained from pathology reports; the anatomic sites of primary cutaneous cancers were then correlated with these findings. RESULTS Among 209 patients, 171 (82%) had clinical parotid involvement. Of these, 28 had clinical neck disease, whereas 143 had parotid disease alone. Thirty-eight (18%) patients had neck disease only. A total of 199 patients were treated surgically, whereas 10 received radiotherapy alone. Surgery included 172 parotidectomies and 151 neck dissections (93 of which were elective). Primary sites were cheek (21.7%), pinna (20.4%), temple (15.8%), forehead (15.8%), postauricular region (5.9%), neck (5.3%), anterior scalp (5.3%), posterior scalp (3.3%), periorbital (3.3%), nose (2.6%), and chin (0.6%). Among pathologically positive necks, level II was most frequently involved (79%). Level IV (13%) and level V (17%) were only involved in extensive lymph node disease, the exception being for isolated level V metastases from the posterior scalp. CONCLUSIONS Primary sites were mainly localized to the lateral aspect of the head. Among patients with cutaneous SCC involving the parotid and neck, level II was the most commonly involved neck level. The distribution of involved nodes suggests that in a patient with parotid involvement and a clinically negative neck with an anterolateral primary, a supraomohyoid neck dissection, always including the external jugular lymph node(s) would be appropriate. In the case of a posterior primary, level V should be dissected as well. In patients with parotid SCC and a clinically positive neck, a comprehensive neck dissection is recommended.

Abstract
BACKGROUND Although most cutaneous squamous cell carcinoma (SCC) is curable by a variety of treatment modalities, a small subset of tumors recur, metastasize, and result in death. Although risk factors for metastasis have been described, there are little data available on appropriate workup and staging of patients with high-risk SCC. OBJECTIVE We reviewed reported cases and case series of SCC in which sentinel lymph node biopsy (SLNB) was performed to determine whether further research is warranted in developing SLNB as a staging tool for patients with high-risk SCC. METHODS The English medical literature was reviewed for reports of SLNB in patients with cutaneous SCC. Data from anogenital and nonanogenital cases were collected and analyzed separately. The percentage of cases with a positive sentinel lymph node (SLN) was calculated. False negative and nondetection rates were tabulated. Rates of local recurrence, nodal and distant metastasis, and disease-specific death were reported. RESULTS A total of 607 patients with anogenital SCC and 85 patients with nonanogenital SCC were included in the analysis. A SLN could not be identified in 3% of anogenital and 4% of nonanogenital cases. SLNB was positive in 24% of anogenital and 21% of nonanogenital patients. False-negative rates as determined by completion lymphadenectomy were 4% (8/213) and 5% (1/20), respectively. Most false-negative results were reported in studies from 2000 or earlier in which the combination of radioisotope and blue dye was not used in the SLN localization process. Complications were reported rarely and were limited to hematoma, seroma, cutaneous lymphatic fistula, wound infection, and dehiscence. CONCLUSIONS Owing to the lack of controlled studies, it is premature to draw conclusions regarding the utility of SLNB in SCC. The available data, however, suggest that SLNB accurately diagnoses subclinical lymph node metastasis with few false-negative results and low morbidity. Controlled studies are needed to demonstrate whether early detection of subclinical nodal metastasis will lead to improved disease-free or overall survival for patients with high-risk SCC.

Abstract
BACKGROUND Metastatic parotid cutaneous squamous cell carcinoma (SCC) is the most common parotid gland malignancy in New Zealand and Australia. The current AJCC TNM staging system does not account for the extent of nodal metastasis. A staging system that separates parotid (P stage) from neck disease (N stage) has been proposed recently. AIM To review the outcome of patients with metastatic head and neck cutaneous SCC treated at our multidisciplinary Head and Neck Service using the proposed staging system. METHOD Consecutive patients were culled from our Head and Neck/Skull Base Database, 1990-2004. These patients were restaged according to the proposed staging system: P stage: P0 = no disease in the parotid (i.e., neck disease only); P1 = metastatic node < or = 3 cm; P2=metastatic node > 3 cm and < or =6 cm, or multiple nodes; and P3 = metastatic node > 6 cm, or disease involving the facial nerve or skull base. N stage: N0=no disease in the neck (i.e., parotid disease only); N1 = single ipsilateral metastatic node < or = 3 cm; and N2 = multiple metastatic nodes, or any node > 3 cm, or contralateral neck involvement. Loco-regional recurrence and disease-specific survival were calculated using the Kaplan-Meier method and comparison of graphs made with the log-rank test. Multivariate analysis using the Cox regression model was carried out to assess the impact of various parameters. RESULTS Sixty-seven patients with metastatic head and neck cutaneous SCC were identified. Thirty-seven patients had parotid metastasis (of whom 13 also had neck disease) while 21 had neck metastasis alone. Nine patients had dermal or soft tissue metastasis. These nine patients were excluded from this series, and data analysis was carried out on the remaining 58 (46 men, 12 women, mean age 71 years) patients. Sixty-seven percent of the patients underwent post-operative adjuvant radiotherapy. The five-year disease-specific survival rate was 54%. Among 56 patients followed up to disease recurrence or for a minimum period of 18 months, the loco-regional recurrence rate was 52%. The presence of parotid disease was an independent prognostic factor on survival (p < 0.01), and P3 fared significantly worse than P1 and P2. Those patients who had both parotid and neck disease fared worse than those who had parotid or neck disease alone (p = 0.01). N2 had a significantly poorer outcome compared with N1 (p < 0.01). Immunosuppression (p = 0.01) and a positive surgical margin (p < 0.01) were significant adverse prognostic factors for survival. Adjuvant radiotherapy, extracapsular spread, and perineural and vascular invasion did not influence survival. Our study demonstrates that the extent of parotid disease is an independent prognostic factor for metastatic head and neck cutaneous SCC.

Abstract
BACKGROUND Cutaneous squamous cell carcinoma (SCC) of the head and neck is a common cancer that has the potential to metastasize to lymph nodes in the parotid gland and neck. Previous studies have highlighted limitations with the current TNM staging system for metastatic skin carcinoma. The aim of this study was to test a new staging system that may provide better discrimination between patient groups. METHODS A retrospective multicenter study was conducted on 322 patients from three Australian and three North American institutions. All had metastatic cutaneous SCC involving the parotid gland and/or neck and all were treated for cure with a minimum followup time of 2 years. These patients were restaged using a newly proposed system that separated parotid disease (P stage) from neck disease (N stage) and included subgroups of P and N stage. Metastases involved the parotid in 260 patients (149 P1; 78 P2; 33 P3) and 43 of these had clinical neck disease also (22 N1; 21 N2). Neck metastases alone occurred in 62 patients (26 N1; 36 N2). Ninety percent of patients were treated surgically and 267 of 322 received radiotherapy. RESULTS Neck nodes were pathologically involved in 32% of patients with parotid metastases. Disease recurred in 105 (33%) of the 322 patients, involving the parotid in 42, neck in 33, and distant sites in 30. Parotid recurrence did not vary significantly with P stage. Disease-specific survival was 74% at 5 years. Survival was significantly worse for patients with advanced P stage: 69% survival at 5 years compared with 82% for those with early P stage (P = 0.02) and for those with both parotid and neck node involvement pathologically: 61% survival compared with 79% for those with parotid disease alone (P = 0.027). Both univariate and multivariate analysis confirmed these findings. Clinical neck involvement among patients with parotid metastases did not significantly worsen survival (P = 0.1). CONCLUSIONS This study, which included a mixed cohort of patients from six different institutions, provides further information about the clinical behavior of metastatic cutaneous SCC of the head and neck. The hypothesis that separation of parotid and neck disease in a new staging system is supported by the results. The benefit of having subgroups of P and N stage is uncertain, but it is likely to identify patients with unfavorable characteristics that may benefit from further research.

Abstract
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.

Abstract
OBJECTIVE Patients with cutaneous squamous cell carcinoma (SCC) may develop metastatic SCC to nodes in the head and neck. Recent data support best outcome with the addition of adjuvant radiotherapy. This study aims to present further supportive evidence. STUDY DESIGN Retrospective chart review. METHODS Patients were identified with metastatic cutaneous SCC to nodes of the head and neck treated with surgery or surgery and adjuvant radiotherapy. Relapse and outcome were analyzed using Cox regression analysis. Disease-free survival and overall survival rates were calculated using Kaplan-Meier survival curves. RESULTS Between 1980 to 2000, 167 patients were treated with curative intent at Westmead Hospital, Sydney. Median age was 67 years (range, 34-95) in 143 men and 24 women with a minimum follow-up of 24 months. Patients underwent surgery (21/167; 13%), or surgery and adjuvant radiotherapy (146/167; 87%). The majority (98/167; 59%) of metastatic nodes were located in the parotid and/or cervical nodes. The remaining 69 (41%) had metastatic cervical nodes (levels I-V). Forty-seven patients (28%) had recurrences, with the majority (35/47; 74%) as locoregional failures. On multivariate analysis, spread to multiple nodes and single-modality treatment significantly predicted worse survival. Patients undergoing combined treatment had a lower rate of locoregional recurrence (20% vs. 43%) and a significantly better 5-year disease-free survival rate (73% vs. 54%; P = .004) compared to surgery alone. CONCLUSIONS In patients with metastatic cutaneous head and neck SCC, surgery and adjuvant radiotherapy provide the best chance of achieving locoregional control and should be considered best practice.

Abstract
BACKGROUND Parotid area lymph node metastasis from primary scalp and facial cutaneous cancers is a poorly recognized clinical entity partly because of the long time lapse between the index lesion and regional spread. METHODS A retrospective review of the University of Wisconsin Tumor Registry and Head and Neck Oncology Tumor Board was performed over a 10-year period from 1989 to 1999. One hundred two patients with a malignant parotid mass were identified. Of these, 20 patients were identified with parotid region squamous cell carcinoma and prior index skin cancer of the face or scalp. These patients were analyzed regarding presentation, diagnostic evaluation, interval between index lesion and metastasis, treatment method, and long-term outcome. RESULTS Approximately 20% of patients (20 of 102) in this series with a malignant parotid mass had presumed metastasis from an identifiable skin primary tumor. The mean time from index lesion to presentation of regional spread was 13.5 months. Seventy percent of the patients (14 of 20) underwent surgery followed by radiation as locoregional therapy, whereas 30% underwent surgery alone. Six (30%) of 20 patients required some degree of facial nerve sacrifice. Three patients (15%) experienced subsequent locoregional failure. Two of six patients from the surgery alone group and one of 14 patients who received surgery plus radiation therapy experienced locoregional relapse. CONCLUSIONS Parotid area lymph node metastases from scalp and facial cutaneous carcinomas require aggressive therapy to optimize locoregional control. The addition of radiotherapy after parotidectomy is important and should be considered for optimal disease control. Selective neck dissection or radiation may be warranted at the time of parotidectomy. This combined approach is associated with high locoregional control rates and is generally well tolerated.
