Background. In-transit metastases from cutaneous squamous cell carcinoma (SCC) may occur in organ transplant recipients and may indicate aggressive disease and poor prognosis. Objective. The objective of this study was to describe in-transit metastases from cutaneous SCC and to identify factors associated with this phenomenon in a series of 21 patients. We also attempted to evaluate outcome with respect to status as an organ transplant recipient or nonorgan transplant recipient. Methods. A multicenter case series of patients was reviewed; factors included clinical presentation, management, and outcome. Results. Twenty-one patients, 15 organ transplant recipients, and 6 nontransplant recipients with in-transit metastases were reviewed. In-transit metastases presented most commonly as discrete, dermal papules distinct from but in the vicinity of the primary tumor site. Histologic differentiation was variable. At a mean follow up of 24 months, 33% the transplant patients had no evidence of disease compared with 80% of nontransplant patients. Thirty-three percent were dead from disease and 33% were alive with nodal or distant metastases. In contrast, 80% of nonimmunosuppressed patients had no evidence of disease and none had died at mean follow-up of 24 months. Conclusion. In-transit metastasis from cutaneous SCC is a unique presentation of metastatic SCC, more commonly described in organ transplant recipients, and is associated with poor prognosis in that group. This description represents the largest experience with in-transit metastases from cutaneous SCC in the literature. [source]


Hyaline globules in ectopic decidua in a pregnant woman with cervical squamous cell carcinoma

DIAGNOSTIC CYTOPATHOLOGY, Issue 9 2009

Abstract Decidual reaction in pelvic lymph nodes has been increasingly documented during pregnancy. This may pose diagnostic difficulty during intraoperative frozen section (FS) and cytological consultation in women undergoing surgical procedures for cervical Squamous cell carcinoma (SCC). A 34-year-woman diagnosed to have invasive SCC (stage IB1) of the cervix at 14th week of her first pregnancy underwent abdominal radical trachelectomy and pelvic lymphadenectomy at 22 weeks of gestation. Cytological smears of two of the lymph nodes from intraoperative FS revealed isolated eosinophilic hyaline globules (HG) measuring 45,50 microns, in addition to large polygonal cells with amphophilic cytoplasm and hypochromatic nuclei and occasional squamous-looking cells with atypical hyperchomatic nuclei. These findings posed a diagnostic dilemma at intraoperative consultation and no definitive diagnosis was rendered. The formlin-fixed, paraffin-embedded histological sections of the same lymph nodes showed ectopic decidua with no evidence of metastatic SCC. Decidual cells are a cause of concern for both cytologists and histopathologists. In pregnant women complicated by cervical cancer intraoperative evaluation of pelvic lymph nodes is of utmost importance in order to adopt the optimal conservative treatment modality. In the absence of clear cut evidence of malignancy, a diagnosis of metastatic SCC should not be rendered. Diagn. Cytopathol. 2009. 2009 Wiley-Liss, Inc. [source]

Abstract Background Metastatic cutaneous cancer is the most common parotid malignancy in Australia, with metastatic squamous carcinoma (SCC) occurring most frequently. There are limitations in the current TNM staging system for metastatic cutaneous malignancy, because all patients with nodal metastases are simply designated N1, irrespective of the extent of disease. The aim of this study was to analyze the influence of clinical stage, extent of surgery, and pathologic findings on outcome after parotidectomy for metastatic SCC by applying a new staging system that separates metastatic disease in the parotid from metastatic disease in the neck. Methods A prospectively documented series of 87 patients treated by one of the authors (COB) over 12 years for clinical metastatic cutaneous SCC involving the parotid gland and a minimum of 2 years follow-up was analyzed. These patients were all previously untreated and were restaged according to the clinical extent of disease in the parotid gland in the following manner. P1, metastatic SCC of the parotid up to 3 cm in diameter; P2, tumor greater than 3 cm up to 6 cm in diameter or multiple metastatic parotid nodes; P3, tumor greater than 6 cm in diameter, VII nerve palsy, or skull base invasion. Neck disease was staged in the following manner: N0, no clinical metastatic disease in the neck; N1, a single ipsilateral metastatic neck node less than 3 cm in diameter; N2, multiple metastatic nodes or any node greater than 3 cm in diameter. Results Clinical P stages were P1, 43 patients; P2, 35 patients; and P3, 9 patients. A total of 21 patients (24%) had clinically positive neck nodes. Among these, 11 were N1, and 10 were N2. Conservative parotidectomies were carried out in 71 of 87 patients (82%), and 8 of these had involved surgical margins (11%). Radical parotidectomy sacrificing the facial nerve was performed in 16 patients, and 6 (38%) had positive margins, (p < .01 compared with conservative resections). Margins were positive in 12% of patients staged P1, 14% of those staged P2, and 44% of those staged P3 (p < .05). Multivariate analysis demonstrated that increasing P stage, positive margins, and a failure to have postoperative radiotherapy independently predicted for decreased control in the parotid region. Survival did not correlate with P stage; however, many patients staged P1 and P2 also had metastatic disease in the neck. Clinical and pathologic N stage both significantly influenced survival, and patients with N2 disease had a much worse prognosis than patients with negative necks or only a single positive node. Independent risk factors for survival by multivariate analysis were positive surgical margins and the presence of advanced (N2) clinical and pathologic neck disease. Conclusions The results of this study demonstrate that patients with metastatic cutaneous SCC in both the parotid gland and neck have a significantly worse prognosis than those with disease in the parotid gland alone. Furthermore, patients with cervical nodes larger than 3 cm in diameter or with multiple positive neck nodes have a significantly worse prognosis than those with only a single positive node. Also, the extent of metastatic disease in the parotid gland correlated with the local control rate. The authors recommend that the clinical staging system for cutaneous SCC of the head and neck should separate parotid (P) and neck disease (N) and that the proposed staging system should be tested in a larger study population. 2002 Wiley Periodicals, Inc.

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.

HN10P METASTATIC CUTANEOUS SQUAMOUS CELL CARCINOMA TO THE PAROTID GLAND

ANZ JOURNAL OF SURGERY, Issue 2007

Purpose With an incidence rate of 300 cases per 100000 population per year, Australia has the highest incidence of cutaneous squamous cell carcinoma (SCC) in the world. Metastatic cutaneous SCC in parotid lymph nodes are aggressive tumours with poor outcomes both in terms of local control and survival. Methodology This study reports a prospective series of 41 consecutive patients with metastatic SCC to the parotid gland in a major teaching hospital in Western Australia over a six-year period from January 2000 to December 2005. Epidemiological, clinical, histopathological and treatment details along with patterns of failure were extracted from the database. The survival and failure curves were calculated using the Kaplan-Meier method. Univariate and multivariate analysis were performed using Cox regression method. Results The five-year absolute survival is 34.2% and the cancer specific survival 39.5%. Local failure was observed in 11 patients for an actuarial rate of local disease free survival of 65.8% at 6 years. Distant failure occurred in two patients for an actuarial distant disease free survival of 89.5% at 6 years. Both univariate and multivariate analysis failed to find any predictors of local or distant failure with statistical significance. Conclusions Multimodality treatment will still fail to locally control or cure at least a third of patients. Previously identified risk factors were not substantiated in this study and may relate to patient numbers. Parotidectomy and post-operative radiotherapy remain the gold standard. Unlike their cutaneous counter parts metastatic SCC to the parotid gland remains an aggressive tumour with current treatment regimes. [source]


Treatment outcomes of small cell carcinoma of the prostate

CANCER, Issue 8 2007
A single-center study
Abstract BACKGROUND. The current study was conducted to determine the clinical characteristics and prognostic features associated with prostatic small cell carcinoma (SCC). METHODS. Between January 1985 and May 2005, 83 patients with SCC of the prostate were identified. Univariate and multivariate Cox proportional hazards modeling were used to assess the prognostic significance of the clinical parameters associated with disease-specific outcomes. RESULTS. Twenty-one patients had no evidence of distant metastasis at the time of the diagnosis of SCC, with the remaining patients demonstrating radiologic or biopsy-proven evidence of metastatic disease. Compared with patients with metastases, patients without metastases at the time of diagnosis were older (P = .001) and had a lower serum lactate dehydrogenase (LDH) level at the time of diagnosis (P = .002). On multivariate analysis, an elevated serum LDH level and low serum albumin at the time of SCC diagnosis was found to be predictive of inferior progression-free survival (P = .02 and P = .008, respectively) and inferior disease-specific survival (DSS) (P = .02 and P = .01, respectively). At the time of last follow-up, 72 patients (87%) had died of disease, with a median DSS duration of 13.1 months (range, 10.7,17.1 months). There was a statistically significant difference noted with regard to the median DSS of patients with nonmetastatic versus those with metastatic SCC (17.7 months [95% confidence interval (95% CI), 12.1,39.2 months] vs 12.5 months [95% CI, 8.1,16.1 months], respectively; P = .03). CONCLUSIONS. SCC of the prostate is a highly aggressive tumor, with serum LDH and albumin levels at the time of diagnosis believed to be predictive of disease-related outcomes. Although palliative, current systemic therapy does not result in cure and does not provide long-term survival for patients with metastases. For patients with nonmetastatic disease, a strategy utilizing systemic and local therapies should be evaluated further. Cancer 2007. 2007 American Cancer Society. [source]
