Kansara S, Oral E, Sarkar I, Sandulache V, Mualla R, Walvekar RR, Ryan W, Ha P. Rate of occult metastasis in lip squamous cell carcinoma: A systematic review and meta-analysis. Head Neck 2024. [PMID: 38497534 DOI: 10.1002/hed.27747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 02/12/2024] [Accepted: 03/12/2024] [Indexed: 03/19/2024] Open
Abstract
OBJECTIVES The rate of occult metastasis in lip cancer is poorly studied. Management of the regional nodal basin in lip cancer is thus controversial. This study sought to understand the true rate of micrometastasis in lip cancer. MATERIALS AND METHODS Systematic review and meta-analysis was conducted of English language studies reporting lip cancer sentinel node biopsy results. Studies were obtained from the PubMed database between the years 2000 and 2023 using the search terms "sentinel node biopsy" and "squamous cell carcinoma." Random effect and fixed effect meta-analyses were performed. RESULTS Thirteen studies met inclusion criteria. Low heterogeneity was noted among the studies, as indicated by the I2 inconsistency test (I2 = 0%). The rate of occult metastasis ranged between 0 and 33% (mean 9%). A total of 189 lip sentinel node biopsies had been performed. Of these, 21 revealed occult nodal metastasis (11.1%, 95% CI 7.36%-16.44%). One step, generalized linear mixed modeling revealed the true rate of occult nodal metastasis to be 10% (95% CI (0.0504, 0.1746), p < 0.0001). CONCLUSION The rate of occult metastasis in lip cancer approaches the threshold for elective management of the regional nodal basin. Sentinel node biopsy is optimally suited for management of high-risk early T stage lip cancer.

Abstract
In this study, we sought to identify the potential impacts of disease characteristics on the prognosis of cutaneous squamous cell carcinoma (cSCC). We searched the PubMed, EmBase, and Cochrane Library databases from their inception until February 2020 to identify studies that investigated the prognosis of cSCC. The pooled effect estimates were applied using odds ratios (OR) and 95% confidence intervals (CI) and were calculated using the random-effects model. Forty-three studies including a total of 21,530 patients and reporting 28,627 cases of cSCC were selected for the final meta-analysis. Poor differentiation (OR, 3.54; 95% CI, 2.30–5.46; P < 0.001), perineural invasion (OR, 3.27; 95% CI, 1.60–6.67; P = 0.001), Breslow greater than 2 mm (OR, 5.47; 95% CI, 2.63–11.37; P < 0.001), diameter greater than 20 mm (OR, 4.62; 95% CI, 2.95–7.23; P < 0.001), and location on temple (OR, 3.20; 95% CI, 1.12–9.15; P = 0.030) were associated with an increased risk of recurrence, whereas immunosuppression status and location on cheek, ear, or lip were not associated with the risk of recurrence. Poor differentiation (OR, 6.82; 95% CI, 4.66–9.99; P < 0.001); perineural invasion (OR, 7.15; 95% CI, 4.73–10.83; P < 0.001); Breslow greater than 2 mm (OR, 6.11; 95% CI, 4.05–9.21; P < 0.001); diameter greater than 20 mm (OR, 5.01; 95% CI, 2.56–9.80; P < 0.001); and location on ear (OR, 2.38; 95% CI, 1.39–4.09; P = 0.002), lip (OR, 2.15; 95% CI, 1.26–3.68; P = 0.005), and temple (OR, 2.77; 95% CI, 1.20–6.40; P = 0.017) were associated with an increased risk of metastasis, whereas immunosuppression status and location on cheek did not affect the risk of metastasis. Finally, poor differentiation (OR, 5.97; 95% CI, 1.82–19.62; P = 0.003), perineural invasion (OR, 6.64; 95% CI, 3.63–12.12; P < 0.001), and Breslow greater than 2 mm (OR, 3.42; 95% CI, 1.76–6.66; P < 0.001) were associated with an increased risk of disease-specific death, whereas diameter; immunosuppression status; and location on ear, lip, and temple did not affect the risk of disease-specific death. We found that differentiation, perineural invasion, depth, diameter, and location could affect the prognosis of cSCC. The potential role of other patient characteristics on the prognosis of cSCC should be identified in further large-scale prospective studies.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is the second most common cancer in humans and its incidence is both underestimated and on the rise. cSCC is referred to in the literature as high-risk cSCC, locally advanced cSCC, metastatic cSCC, advanced cSCC, and aggressive cSCC. These terms can give rise to confusion and are not always well defined. In this review, we aim to clarify the concepts underlying these terms with a view to standardizing the description of this tumor, something we believe is necessary in light of the new drugs that have been approved or are in development for cSCC.

Abstract
Difficulty in precise decision making on necessity of surgery is a major problem when managing oral squamous cell carcinomas (OSCCs) with clinically negative neck. Therefore, use of clinical and histopathological parameters in combination would be important to improve patient management. The main objective is to develop a model that predicts the presence of nodal metastasis in patients with OSCC.623 patients faced neck dissections with buccal mucosal or tongue squamous cell carcinoma (SCC) were selected from patients’ records. Demographic data, clinical information, nodal status, Depth of invasion (DOI) and pattern of invasion (POI) were recorded. The parameters which showed a significant association with nodal metastasis were used to develop a multivariable predictive model (PM). Univariate logistic regression was used to estimate the strengths of those associations in terms of odds ratios (OR). This showed statistically significant associations between status of the nodal metastasis and each of the following 4 histopathological parameters individually: size of the tumour (T), site, POI, and DOI. Specifically, OR of nodal metastasis for tongue cancers relative to buccal mucosal cancers was 1.89, P-value < 0.001. Similarly, ORs for POI type 3 and 4 relative to type 2 were 1.99 and 5.83 respectively. A similar relationship was found with tumour size; ORs for T2, T3, and T4 compared to T1 were 2.79, 8.27 and 8.75 respectively. These four histopathological parameters were then used to develop a predictive model for nodal metastasis. This model showed that probability of nodal metastasis is higher among tongue cancers with increasing POI, with increasing T, and with larger depths while other characteristics remained unchanged. The proposed model provides a way of using combinations of histopathological parameters to identify patients with higher risks of nodal metastasis for surgical management.

Abstract
IMPORTANCE To date, the magnitude of association and the quality of evidence for cutaneous squamous cell carcinoma (cSCC) and risk factors for outcomes have not been reviewed and analyzed systematically. OBJECTIVE To systematically analyze all published data on risk factors for recurrence, metastasis, and disease-specific death (DSD) of cSCC. DATA SOURCES Comprehensive search of Ovid MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus, from each database's inception to May 14, 2015. STUDY SELECTION Inclusion criteria were studies of at least 10 patients, comparative data for at least 1 cSCC risk factor, and an outcome of interest. Exclusion criteria were noncutaneous squamous cell carcinoma (SCC), anogenital SCC, inability to extract cSCC data from other malignancy data, SCC in situ, Marjolin ulcer, and genetic disorders predisposing to cSCC. DATA EXTRACTION AND SYNTHESIS Two reviewers independently abstracted the data. Meta-analysis was performed using the random-effects model. Risk of bias was assessed by the Newcastle-Ottawa Scale. MAIN OUTCOMES AND MEASURES A priori outcomes were recurrence, metastasis, and DSD. RESULTS Thirty-six studies (17 248 patients with 23 421 cSCCs) were included. Significant risk factors for recurrence were the following: Breslow thickness exceeding 2 mm (risk ratio [RR], 9.64; 95% CI, 1.30-71.52), invasion beyond subcutaneous fat (RR, 7.61; 95% CI, 4.17-13.88), Breslow thickness exceeding 6 mm (RR, 7.13; 95% CI, 3.04-16.72), perineural invasion (RR, 4.30; 95% CI, 2.80-6.60), diameter exceeding 20 mm (RR, 3.22; 95% CI, 1.91-5.45), location on the temple (RR, 3.20; 95% CI, 1.12-9.15), and poor differentiation (RR, 2.66; 95% CI, 1.72-4.14). Significant risk factors for metastasis were: invasion beyond subcutaneous fat (RR, 11.21; 95% CI, 3.59-34.97), Breslow thickness exceeding 2 mm (RR, 10.76; 95% CI, 2.55-45.31), Breslow thickness exceeding 6 mm (RR, 6.93; 95% CI, 4.02-11.94), diameter exceeding 20 mm (RR, 6.15; 95% CI, 3.56-10.65), poor differentiation (RR, 4.98; 95% CI, 3.30-7.49), perineural invasion (RR, 2.95; 95% CI, 2.31-3.75), immunosuppression (RR, 1.59; 95% CI, 1.07-2.37), and location on the temple (RR, 2.82; 95% CI, 1.72-4.63), ear (RR, 2.33; 95% CI, 1.67-3.23), or lip (RR, 2.28; 95% CI, 1.54-3.37). Significant risk factors for DSD were: diameter exceeding 20 mm (RR, 19.10; 95% CI, 5.80-62.95), poor differentiation (RR, 5.65; 95% CI, 1.76-18.20), location on the ear (RR, 4.67; 95% CI, 1.28-17.12) or lip (RR, 4.55; 95% CI, 1.41-14.69), invasion beyond subcutaneous fat (RR, 4.49; 95% CI, 2.05-9.82), and perineural invasion (RR, 4.06; 95% CI, 3.10-5.32). Evidence quality was considered low to moderate. CONCLUSIONS AND RELEVANCE Tumor depth is associated with the highest RR of local recurrence and metastasis of cSCC, and tumor diameter exceeding 20 mm is associated with the highest RR of DSD. Unified, consistent collection and reporting of risk factors in a prospective, multicentered effort are needed to further understand the increasing incidence of cSCC.

Abstract
BACKGROUND Most patients with cutaneous squamous cell carcinoma (cSCC) of the head and neck (HN) are at low-risk (<5%) of developing metastatic SCC to regional lymph nodes. However, patients with unfavorable clinicopathologic factors often are under appreciated by clinicians but remain at higher risk for developing metastatic lymph node disease and dying. METHODS Patients were identified who had metastatic cSCC to lymph nodes (parotid and cervical) of the HN and who were treated within the context of a multidisciplinary HN cancer service between 1980 and 2005 at Westmead Hospital (Sydney, Australia). Relevant patient details and data from primary lesions were analyzed and reported. RESULTS In total, 266 patients were treated with curative intent. The median patient age was 69 years among 219 males and 47 females. The majority of metastatic lymph nodes (162 of 266 lymph nodes; 61%) were located in the parotid with or without cervical lymph node involvement. The median tumor thickness was 6 mm (range, 0.5-28 mm), and the median tumor size was 15 mm (range, 3-70 mm). Most tumors (65%) that measured >or=5 mm in thickness, and 30% of patients had lesions that measured >or=2 cm in greatest dimension. Recurrent cSCC was present in 15% of patients, and most lesions were located within the lymphatic drainage of the parotid on the temple/forehead (28%), on or around the ear (20%), or on the cheek (12%). Forty-six percent of patients had moderately or poorly differentiated cSCC, and 5% of patients were immunosuppressed. A minority of patients (27%) did not have an identifiable index lesion. CONCLUSIONS Data from this large, prospective data base, in concordance with other series, suggested that a patient with thick cSCC (>4-5 mm) located in proximity to the parotid gland can be considered at high-risk. Increasing lesion size and recurrence contribute to this risk.

Abstract
BACKGROUND Oral mucosa squamous cell carcinoma (OSCC) has locoregional evolution, with frequent neck involvement (the most important parameter for prognosis). There are still many doubts concerning the best way to approach N0 neck disease in early-stage lesions (T1 and T2). Many parameters have been studied to identify N0 patients with a high likelihood of harboring occult node metastases or of having them develop. METHODS A review of the studies analyzing "tumor thickness"/"depth of invasion" in predicting regional metastases and survival was undertaken. RESULTS The literature suggests that "tumor thickness"/"depth of invasion" is a reliable parameter for predicting regional nodal involvement and survival in OSCC. CONCLUSIONS Authors are in substantial agreement regarding the reliability of tumor thickness. The lack of comparable study groups, measurement techniques, and cut-off values points to the need for further studies so as to reach a consensus and to develop therapy protocols that include tumor thickness.

Abstract
SUMMARY Non-melanoma skin 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, usually excision, is highly curative. However, a subset of the population are diagnosed with a high-risk cutaneous squamous cell carcinoma, defined as a patient having a higher risk of subclinical metastases to regional lymph nodes based on unfavourable primary lesion features and patient factors. Despite treatment, patients developing metastatic cutaneous squamous cell carcinoma experience mortality and morbidity usually as a consequence of uncontrolled metastatic nodal disease. It is therefore important that clinicians treating skin cancers have an understanding and awareness of these high-risk patients. The aim of this article is to discuss the features that define a high-risk patient and to present some of the issues pertinent to their treatment.

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
Dentre os cânceres do lábio de 90% a 95% dos casos afetam o lábio inferior, sendo o carcinoma espinocelular o mais freqüente. A classificação TNM sintetiza as características clínicas do tumor, permitindo realizar um prognóstico e possibilitando comparações dos resultados. Relaciona três parâmetros: tamanho do tumor (T), propagação aos gânglios linfáticos regionais (N) e metástases à distância (M), mas estabelece padrões a partir de 2cm. Para o carcinoma espinocelular do lábio lesões com 2cm são extremamente grandes. OBJETIVO: O objetivo deste estudo é verificar a relação entre as características epidemiológicas, clínicas, evolutivas e histopatológicas do carcinoma espinocelular do lábio tendo como parâmetro lesões de tamanhos a partir de 0,5cm. CASUÍSTICA E MÉTODO: Foi elaborado um estudo retrospectivo transversal em pacientes com carcinoma espinocelular do lábio, no período 1993-2000, em São Paulo, Brasil. Estudou-se prontuários, laudos originais dos exames histopatológicos e lâminas de tumores de pacientes com carcinoma espinocelular do lábio. Os tumores foram classificados de 0.5 em 0.5cm, sendo verificado o tipo, o grau de diferenciação histológica, a presença de desmoplasia, as invasões muscular, neural e vascular, e o tipo de infiltrado inflamatório. RESULTADOS: A análise estatística mostrou que metástases e recidivas não dependem da cor de pele ou do sexo dos pacientes e que há independência entre a localização do tumor, no lábio superior ou inferior, e a incidência de metástases e recidiva. Houve correlação entre o tamanho da lesão a partir de 0,5cm e a ocorrência de metástases e recidiva. Verificou-se que o tamanho da lesão determina a invasão em outros tecidos. O infiltrado inflamatório verificado em todas as lesões era linfoplasmocitário e, em algumas, associado com eosinófilos sem relação com o tamanho do tumor. CONCLUSÃO: Tumores menores que 2cm podem apresentar comportamentos evolutivos distintos, sob o ponto de vista clínico e histopatológico. O tipo mais prevalente de lesão é o ulcerativo e o que mais metastatiza e recidiva é o úlcero-vegetante. Os tipos úlcero-vegetante e vegetante estão ligados a lesões de maior tamanho. O tamanho do tumor se relaciona, de forma semelhante, com os graus II e III, nos quais ocorrem os maiores índices de metástases e recidivas. O tumor invade em ordem decrescente de freqüência músculos, nervos e vasos sanguíneos, e esta pode ser prevista pelo tamanho da lesão. É necessária a invasão dos músculos para a ocorrência de metástases, sendo que os vasos sanguíneos somente podem estar implicados quando há invasão concomitante dos nervos. A desmoplasia está diretamente relacionada ao tamanho da lesão e à ocorrência de metástases.

BACKGROUND Squamous cell carcinoma (SCC) of the lower lip is a common malignancy in Australia. Surgical excision and/or radiotherapy are used in treatment, and are regarded as equally effective. METHODS A retrospective review of 323 patients treated at the Peter MacCallum Cancer Institute with either surgical excision and/or radiotherapy, evaluated disease recurrence, cause-specific mortality, and the incidence of metachronous lesions. RESULTS Recurrence-free survival at 10 years was estimated to be 92.5%, and cause-specific survival at 10 years was estimated to be 98.0%. Equivalent rates of local control were obtained with surgery and radiotherapy. Recurrence was related to tumour stage and differentiation. A high incidence of metachronous lesions was noted, 25 patients had a lesion prior to presentation and 33 patients developed second lip lesions during the study period. CONCLUSIONS Squamous cell carcinoma of the lower lip is well treated with surgery or radiotherapy. The preferred treatment for most patients with SCC of the lower lip in the Australian population is surgical excision. This study has shown a significant incidence of metachronous lip neoplasia, except in those patients whose whole lip had been resurfaced.

Abstract
BACKGROUND Controversy still exists as to whether radiotherapy or surgery is the preferable therapeutic modality for stage I squamous cell carcinoma of the lower lip. Therefore, a retrospective study was undertaken to compare the results of both treatment modalities. METHODS The results of 90 patients who received radiotherapy and 166 patients who underwent surgery as the primary form of treatment for their stage I primary squamous cell carcinoma of the lower lip were evaluated. Tumor size and histological grade of differentiation were assessed. RESULTS Local control rates were the same with radiotherapy or surgery. Overall survival rates for both groups of patients were similar as well. Disease-free survival rates in the patients who underwent radiotherapy were significantly lower compared with the surgically treated group. This was due to a higher occurrence of regional metastases in the patients who received radiotherapy. Univariate analysis showed that irradiated patients had a statistically significant greater tumor size. The difference of histological differentiation between the groups was also statistically significant, the poorly differentiated being more common in the irradiated group. Multivariate analysis showed that only tumor size carried significant independent prognostic information. CONCLUSIONS The cure rates of stage I squamous cell carcinoma of the lower lip are favorable whether treated by radiotherapy or surgery, and local control rates are similar. The radiotherapeutic treated group showed an increased incidence of cervical metastases, which was due to the more advanced tumor size in these patients.

Abstract
OBJECTIVE Among the histologic features of squamous cell carcinoma of the lower lip, maximum tumor thickness in particular is a predictor of regional nodal metastatic spread and thus an important parameter in treatment planning. The purpose of this study was to investigate the relationship between maximum tumor thickness in punch biopsies and maximum tumor thickness in subsequent surgical specimens. STUDY DESIGN This retrospective study examined the relationship between maximum tumor thickness in punch biopsies with that in subsequent surgical specimens obtained in 72 patients with clinical stage I squamous cell carcinoma of the lower lip. RESULTS A correlation between maximum tumor thickness in punch biopies and in subsequent surgical specimens was found only for tumors with a thickness less than 3 mm. CONCLUSIONS Reliable predictive information could be obtained from punch biopsies with a maximum tumor thickness less than 3 mm. When the maximum tumor thickness exceeds 3 mm, better information may be obtained from either a large incisional biopsy or the surgical specimen.

Abstract
Previous work has suggested a key role of dendritic cells in antineoplastic immunity. The course of mycosis fungoides and cancers of the lung, colon, thyroid and stomach has been associated with dendritic cell response to the primary tumor. However, this has not been reported for cutaneous or mucosal squamous cell carcinoma (SCC). Thirty-six cases of primary SCC of the lip mucosa or vermillion border, including nine cases with regional metastasis, were studied to investigate the relationship of dendritic cell density with age, tumor grade, mitotic rate, diameter, ulceration, depth of invasion, muscle invasion, tumor-infiltrating lymphocytes (TILs) and metastasis. Dendritic cells were identified using S100 immunohistochemistry, and their peritumor and intratumor density (peri-S100D and intra-S100D) were determined. The mean peri-S100D was 314 +/- 50/mm2. High peri-S100D was associated with lower rate of metastasis (P = 0.03), and no case with peri-S100D > 311/mm2 metastasized. Peri-S100D inversely correlated with depth of invasion (P = 0.04) and ulceration (P = 0.02), and positively associated with TILs (P = 0.02). The mean intra-S100D was 317 +/- 42/mm2. Intra-S100D did not quantitatively correlate with metastasis; however, no metastasis occurred when intra-S100D exceeded 515/mm2. Intra-S100D correlated with brisk TILs (P = 0.04). These results suggest a functional role of dendritic cells in the immune response to SCC. Peri-S100D may be a prognostic indicator.

Abstract
PURPOSE A retrospective study was undertaken to evaluate the results of surgical treatment of primary squamous cell carcinoma of the vermilion border of the lower lip and to identify parameters of the primary tumor that may predict local recurrence and regional metastasis. PATIENTS AND METHODS From 1979 through 1992, 184 consecutive patients with a primary squamous cell carcinoma of the lower lip underwent surgical excision as a primary treatment. There were 166 (90.2%) men and 18 (9.8%) women, with a mean age of 66 years. Most cases (92.9%) were stage I tumors. Most of the tumors were well and moderately differentiated squamous cell carcinomas (93.5%). Minimal follow-up was 2 years, with a mean of 56 months. Disease control was achieved in 165 (89.7%) patients. Local recurrence and regional metastasis occurred in 9 (4.9%) and 10 (5.4%) patients, respectively. Local failures were treated successfully by either surgery or radiation therapy. Regional metastases were treated in nine patients by neck dissection, followed in eight cases by radiation therapy. One patient developed distant metastasis. RESULTS Five- and 10-year overall survival rates were 78% and 61%, respectively, whereas the disease-free survival rates at 5 and 10 years were 86% and 81%, respectively. Multivariate analysis indicated that local recurrence was significantly associated with large tumor size and surgical margins containing squamous cell carcinoma. Increasing tumor thickness, an infiltrative invasion pattern, and perineural invasion were significant prognostic indicators of regional metastasis. CONCLUSION Surgical treatment for small squamous cell carcinomas of the lower lip has a favorable prognosis. Particular parameters of the primary tumor seem to predict the chance of development of local recurrence and regional lymph node metastasis.

Abstract
BACKGROUND Mohs micrographic surgery (MMS) is believed to be a highly effective treatment of squamous cell carcinoma (SCC) of the lip. OBJECTIVE The goals of our study were to determine the long-term (5-year) outcome of patients treated with MMS for SCC of the lip and to identify factors associated with tumor recurrence. METHODS Clinical and histopathologic data from 50 consecutive cases of SCC of the lip treated with MMS were retrospectively reviewed. RESULTS There were no tumor-related deaths or metastases. Forty-six patients (92%) remained free of disease. Four patients (8%) were diagnosed with SCC at the surgical site after MMS. Recurrent lesions tended to be superficial and occurred in the setting of severe actinic cheilitis. The average time to diagnosis after MMS was 2.5 years. All patients with recurrent disease were treated with further MMS and had successful results. No recurrences were seen among patients who received adjuvant treatment for actinic cheilitis with the carbon dioxide (CO2) laser, had clinical lesions 1 cm or less in diameter, or had post-MMS defects 2 cm or less in diameter. CONCLUSION MMS is highly effective for treating both primary and recurrent SCC of the lip. Treatment of coexisting actinic cheilitis may lower the risk for local recurrence after MMS.

Abstract
Cutaneous squamous cell carcinoma (SCC) is the second most common form of skin cancer and is treated frequently by dermatologists. For many years, the level of knowledge regarding treatment of SCC has taken a backseat to the treatment of basal cell carcinoma and malignant melanoma. As dermatologists become more surgically proficient and assume a leading role in the surgical care for cutaneous carcinoma, a thorough knowledge of the appropriate management of SCC is of paramount importance. In particular, it is essential to recognize that, unlike basal cell carcinoma, certain SCC have a significant metastatic potential and require more comprehensive care. This review targets the etiology, pathogenesis, clinical presentation, histopathology, and treatment of SCC. Particular attention is focused on providing appropriate care for SCC and recognizing and arranging appropriate management for high risk SCC.

Abstract
The histological features of 66 cases of squamous cell carcinoma of the lip were studied in an attempt to define prognostic parameters. Features that correlated with an increased risk of metastasis included histological grade of the tumour at the base and the surface, the tumour thickness, presence of stromal sclerosis, and the presence of muscle and perineural invasion.

Abstract
BACKGROUND Patients with head and neck squamous cell carcinoma die of locoregional recurrence and those with basal cell carcinoma suffer cosmetic and functional changes from its treatment. Prognostic factors are based upon tumor characteristics and host factors. Flow cytometry can assist with prognostic characterization of nonmelanoma skin cancer. METHODS Specimens from 40 sequential patients with head and neck nonmelanoma skin cancers were prospectively obtained at the time of surgery. The patients were followed for four years for local recurrence and metastasis to regional lymph nodes. Samples were prepared from frozen specimens using a modification of the Vindelov procedure. RESULTS DNA aneuploidy or tetraploidy and histology of well differentiated squamous cell carcinoma were significantly associated with metastasis to regional lymph nodes. Direct extension of tumor below the adipose tissue was associated with an S-phase greater than 4.1 and a proliferative fraction greater than 5.5. No tumors recurred at the site of surgical resection. CONCLUSIONS The measurement of DNA ploidy of well differentiated squamous cell carcinoma, and proliferative capacity or S-phase of both basal cell and squamous cell carcinomas assists in predicting the biologic proclivity for locoregional invasion or metastasis of nonmelanoma skin cancer. Identification of aggressive tumors at the time of surgery may offer the opportunity for prevention of lethal metastasis by using adjunctive therapy.

Abstract
BACKGROUND Recent studies have shown that tumor growth beyond a certain size requires angiogenesis. Microvessel density has, moreover, correlated with metastatic risk in some tumors. Invasive squamous carcinoma (SCC) can develop in the epithelium of the lip and metastasize even when relatively small. This study investigates neovascularization and its relationship to metastatic risk in this tumor. METHODS All 41 primary SCCs of the lip diagnosed at our institution from 1960 to 1991 were immunostained for factor VIII. Microvessel grade (Mv) from 1+ to 4+ and the average number of vessel profiles (TMvD) in the highest density 200 x (0.785 mm2) and 400 x (0.196 mm2) microscopic fields were determined. TMvDs were compared with those of adjacent non-tumor tissue (NTMvD). Normalized counts (TMvDns) were calculated as TMvD/NTMvD. TMvDs and TMvDns of metastasizing (N = 10) and non-metastasizing (N = 31) tumors were compared (student t-test). RESULTS In all SCCs TMvDs exceeded NTMvDs (50 vs. 35 at 200 x, P = 0.0014, and 26 vs. 14 at 400 x, P < 0.0001). Metastasizing and non-metastasizing tumors did not, however, differ in Mv, TMvD, or TMvDn. CONCLUSIONS Angiogenesis develops, but is not quantitatively related to metastatic risk, in primary invasive squamous cell carcinoma of the lip.
