RESUMO

BACKGROUND: There are no randomized controlled trials to guide surgical margins for invasive head and neck (H&N) melanoma using conventional excision. Mohs micrographic surgery (MMS) has shown improved local recurrence rates and survival for invasive H&N melanomas. OBJECTIVE: Determine local recurrence (LR), nodal recurrence, and distant recurrence rates, and disease specific survival for invasive melanoma of the H&N treated with MMS. METHODS: A retrospective multicenter study of 785 cases of invasive H&N melanoma treated with MMS using frozen sections with melanoma antigen recognized by T-cells 1 immunohistochemical staining was performed to evaluate long-term outcomes over 12-years. RESULTS: 785 melanomas (thickness: 0.3 mm-8.5 mm) were treated with MMS. LR, nodal recurrence, and distant recurrence rates were 0.51% (4/785), 1.0% (8/785), and 1.1% (9/785) respectively. For T1, T2, T3, and T4 tumors LR was 0.16% (1/636), 1.18% (1/85), 2.22% (1/45), and 5.26% (1/19), respectively. Five and 10-year disease specific survival were 96.8% (95% CI 95.0% to 98.5%) and 93.4% (95% CI 88.5% to 98.3%). LIMITATIONS: A nonrandomized retrospective study. CONCLUSION: MMS achieves significant improvements in LR compared to a meta-analysis of historical cohorts of patients treated with conventional excision. MMS should be considered an important surgical option for invasive H&N melanoma.

RESUMO

BACKGROUND: The efficacy of Mohs micrographic surgery (MMS) in treating cutaneous squamous cell carcinoma has been demonstrated. The cost effectiveness of MMS has rarely been studied to support the perceived higher cost. OBJECTIVE: Perform a cost-effectiveness analysis to determine whether MMS is cost effective over wide local excision (WLE) for Brigham and Women's Hospital tumor stage T2a cutaneous squamous cell carcinoma over a 5-year period. METHODS: A Markov model with a 5-year time horizon was created using variables from published data. Costs in United States dollars and quality-adjusted life-years (QALY) were calculated. RESULTS: MMS was $333.83 less expensive ($4365.57 [95% CI, $3664.68-$6901.66] vs $4699.41 [95% CI, $3782.94-$10,019.31]) than WLE. MMS gained 2.22 weeks of perfect health (3.776 QALY [95% CI, 3.774-3.777] for MMS and 3.733 QALY [95% CI, 3.728-3.777]) over 5 years. The incremental cost-effectiveness ratio was -$7,822.19. MMS had a 99.9% probability of being more cost effective than WLE. Annualized savings of choosing MMS over WLE would be $200 million and over 25,000 QALY. MMS could cost 3.1 times its current rate and remain cost effective. LIMITATIONS: Relied on data from external retrospective sources. CONCLUSION: MMS is less costly and more effective than WLE and should be strongly considered for stage T2a cSCC, given improvements in costs and QALY.

RESUMO

BACKGROUND: Information about the frequency and timing of subsequent cutaneous squamous cell carcinoma (cSCC), along with associated risk factors, is limited. However, this information is crucial to guide follow-up care for these patients. OBJECTIVE: To evaluate the risk and timing of subsequent cSCC in patients who presented with an initial diagnosis of cSCC. METHODS: Retrospective review of an institutional review board-approved, single-institution registry of invasive cSCC. All patients had at least 2 primary cSCCs diagnosed on 2 separate dates 2 months apart. RESULTS: A total of 299 primary cSCCs were included. At 6 months from initial cSCC diagnosis, 18.06% (n = 54) of patients developed subsequent cSCC; at 1 year, 31.77% (n = 94); at 3 years, 67.56% (n = 202); and at 5 years, 87.96% (n = 263) developed subsequent cSCC. Risk factors associated with subsequent cSCC include age at initial diagnosis (hazard ratio [HR], 1.02; 95% confidence interval, 1.004-1.027; P = .008), T2 stage (HR, 1.66; 95% CI, 1.07-2.57; P = .025), and poor tumor grade. Tumor grades well, moderate, and unknown have HRs of 0.21 (P < .001), 0.16 (P .001), and 0.25 (P = .001), respectively. CONCLUSIONS: Of patients who develop subsequent cSCC, 18.06% do so within 6 months, and 31.77% do so within 1 year of initial cSCC diagnosis. Patients with advanced age, poor histologic differentiation, and American Joint Committee on Cancer T2 stage are at highest risk. Close clinical follow-up after the initial diagnosis is recommended.

RESUMO

BACKGROUND: Brigham and Women's Hospital stage T2a squamous cell carcinomas, demonstrating a single high-risk feature, have a low risk of metastasis and death but an increased risk of local recurrence. Little evidence exists for the best treatment modality and associated outcomes in T2a squamous cell carcinoma. OBJECTIVE: We aimed to compare outcomes for T2a squamous cell carcinoma treated by Mohs micrographic surgery compared with wide local excision with permanent sections. METHODS: Retrospective review of an institutional review board-approved single-institution registry of T2a squamous cell carcinoma. RESULTS: Three hundred sixty-six primary T2a tumors were identified, including 240 squamous cell carcinomas (65.6%) treated with Mohs micrographic surgery and 126 (34.4%) treated with wide local excision. A total of 32.5% of patients were immunosuppressed and mean oncologic follow-up was 2.8 years. Local recurrence was significantly more likely after wide local excision (4.0%) than after Mohs micrographic surgery (1.2%) (P = .03). Multiple logistic regression demonstrated immunocompromised state (odds ratio [OR] 5.1; 95% confidence interval [CI] 1.1-23.3; P = .03) and wide local excision (OR 4.8; 95% CI 1.1-21.6; P = .04) associated with local recurrence; and wide local excision (OR 7.8; 95% CI 2.4-25.4; P < .001), high-risk head and neck location (OR 8.3; 95% CI 1.8-38.7; P = .004), and poor histologic differentiation (OR 4.7; 95% CI 1.4-15.4; P = .03) associated with poor outcomes (overall recurrence or disease-specific death). CONCLUSION: Mohs micrographic surgery provides improved outcomes in Brigham and Women's Hospital T2a squamous cell carcinoma.

RESUMO

BACKGROUND: Skin cancer commonly occurs on areas that are salient to body image perception (i.e., head and neck). Patients with head and neck skin cancer (HNSC) may experience negative body image perceptions related to their disease, which is concerning, given the numerous negative sequelae of poor body image. However, there are no existing disease-specific measures of body image concerns in HNSC. OBJECTIVE: To develop and examine the psychometric properties of a brief self-report, disease-specific measure of body image concerns in patients with HNSC-the Body Image Questionnaire (BIQ). MATERIALS AND METHODS: Patients with HNSC completed the BIQ before (n = 239) and 6 months after (n = 80) treatment with Mohs micrographic surgery. Analyses examined the internal consistency, convergent validity, and factor structure of the BIQ. RESULTS: Internal consistency reliability was acceptable, and the measure demonstrated convergent validity with well-being. Four dimensions underlie the BIQ: appearance satisfaction, appearance avoidance, head/neck/skin-specific dissatisfaction, and perceived change. CONCLUSION: The BIQ is a valid and internally reliable disease-specific instrument that measures body image concerns in patients with HNSC.

RESUMO

BACKGROUND: Most skin cancers occur on the head and neck, areas of the body that are significant to an individual's body image (BI) perception. Poor BI is a robust risk factor for depression and decreased quality of life. Thus, patients with nonmelanoma head and neck skin cancer (NMHNSC) may be more vulnerable to BI disturbance and the negative sequelae of poor BI. OBJECTIVE: Describe the nature of BI concerns in patients diagnosed with NMHNSC and assess how BI changes with treatment. METHODS AND MATERIALS: Patients undergoing Mohs micrographic surgery (MMS) for NMHNSC completed assessments of BI and well-being before (N = 239) and 6 months after (N = 80) treatment with MMS. Demographic and tumor data were gathered through retrospective chart review. RESULTS: Body image improved significantly 6 months after MMS, and the magnitude of this change was large (η = 0.18). Repair length (length of final scar irrespective of repair type) >4 cm predicted poorer BI at 6-month follow-up. CONCLUSION: Patients' BI improves after treatment with MMS for NMHNSC.

RESUMO

BACKGROUND: Atopic dermatitis (AD) is the most common chronic pediatric skin disease, and it can profoundly affect a family's quality of life. Children with flaring AD often seek treatment in emergency departments (EDs), which leads to expensive care and ineffective long-term disease control. OBJECTIVES: The objective of the current study was to determine the effect of a pediatric dermatology service (PDS) on ED use and charges and of disease outcomes for patients diagnosed with AD before and after establishing an intramural PDS. METHODS: This retrospective study reviewed electronic medical records of patients presenting to an urban children's hospital ED with diagnoses encompassing the terms AD, eczema, dermatitis and International Classification of Diseases, Ninth Revision (ICD-9) codes 691.8 and 692.9 during the year before (pre-PDS period) and 3 years after establishing a PDS. RESULTS: There were 205 ED visits for dermatitis in the pre-PDS period and 130 in the with-PDS period, a 36.6% decrease (p < 0.001). In the pre-PDS period, 53.7% (n = 110/205) of patients presenting to the ED had moderate dermatitis, compared with 26.2% (n = 34/130) in the with-PDS period, a 69.1% decrease (p < 0.001). Total ED charges were $142,885 for the pre-PDS period and $90,610 for the with-PDS period, a $52,275 decrease. CONCLUSIONS: This study provides a salient example of achieving the triple aim of health care reform: improving health outcomes (decreased ED visits) improving the patient experience (transitioning care from the ED to the more appropriate ambulatory clinical setting), and decreasing the cost of care (decreased ED charges).

RESUMO

We report a 2-month-old boy with a painful ulcerated hemangioma on the lower mucosal lip extending to the vermillion border that caused feeding difficulty. It was successfully treated with topical brimonidine 0.2% and timolol 0.5%, a combination selective α2 -adrenergic agonist and nonselective ß-blocker. After 6 weeks of treatment, the lesion reepithelialized and the patient's symptoms and functional complications resolved. Brimonidine 0.2% timolol 0.5% ophthalmic solution is an emerging alternative treatment for hemangiomas, offering the potential to target hemangioma growth through two synergistic mechanisms (ß-inhibition and α2 -agonism) that may be especially effective for ulcerated lesions, the most common complication of infantile hemangiomas.

RESUMO

BACKGROUND: Human infants are frequently hospitalized due to infection with the paramyxovirus respiratory syncytial virus (RSV). However, very little is known about the neonatal response to paramyxoviral infection. Here, a neonatal model of paramyxoviral infection is developed using the mouse pathogen Sendai virus (SeV). RESULTS: Adult mice infected with SeV developed a predominantly neutrophilic inflammatory cell influx and a concomitant reduction in lung function, as determined by oxygen saturation. In contrast, neonates with SeV had significantly reduced inflammation and normal lung function. Surprisingly, infected neonates had similar viral loads as adult mice. A reduced neutrophil influx in the neonates may be due in part to reduced expression of both CXCL2 and intracellular adhesion molecule-1 (ICAM-1). Expression of IFN-γ and TNF-α increased in a dose-dependent manner in adult lungs, but neonates did not increase expression of either of these cytokines, even at the highest doses. Importantly, the expression of the RIG-I-like receptors (RLRs) was delayed in the neonatal mice, which might have contributed to their reduced inflammation and differential cytokine expression. CONCLUSIONS: Neonatal mice developed similar SeV titers and cleared the virus with similar efficiency despite developing a dramatically lower degree of pulmonary inflammation compared to adults. This suggests that inflammation in the lung may not be required to control viral replication. Future studies will be needed to determine any effect the reduced inflammation may have on the development of a protective memory response in neonates.

RESUMO

BACKGROUND/AIM: Satellitosis/in-transit metastasis (S-ITM) has prognostic value in melanoma and Merkel cell carcinoma, but is not incorporated into cutaneous squamous cell carcinoma (cSCC) staging. PATIENTS AND METHODS: From our IRB-approved registry, patients with high-risk cSCC, including patients with S-ITM, were identified. Univariate (UVA) and multivariate (MVA) analyses were performed to compare disease progression (DP) and overall survival (OS). Cumulative incidence of DP and OS analyses were performed using Fine-Gray and Kaplan-Meier methods, respectively. RESULTS: A total of 18 S-ITM subjects were compared to 247 high risk subjects including T3N0 (n=143), N1-N3 without extranodal extension (ENE) (n=56), N1-N3 with ENE (n=26) and M1 disease (n=22). Median follow up was 16.5 months. Three-year rates of DP were 22% for T3N0, 42% for S-ITM, 48% for T4 bone invasion, 50% for N1-N3 without extranodal extension (ENE), 53% for N1-N3 with ENE, and 66% for M1. Patients with S-ITM did not experience significantly worse DP compared to those with T3N0 (HR=1.96, 95%CI=0.8-4.9; p=0.14). CONCLUSION: Cutaneous SCC patients with S-ITM experienced outcomes similar to locally advanced non-metastatic cSCC patients. Larger studies are needed to guide incorporation into staging systems.

RESUMO

Recent guidelines from the American Joint Committee on Cancer (AJCC) and National Comprehensive Cancer Network (NCCN) have been proposed for the assessment of "high-risk" cutaneous squamous cell carcinomas (cSCCs). Though different in perspective, both guidelines share the common goals of trying to identify "high-risk" cSCCs and improving patient outcomes. Thus, in theory, both definitions should identify a similar proportion of "high-risk" tumors. We sought to evaluate the AJCC and NCCN definitions of "high-risk" cSCCs and to assess their concordance. Methods. A retrospective review of head and neck cSCCs seen by an academic dermatology department from July 2010 to November 2011 was performed. Results. By AJCC criteria, most tumors (n = 211,82.1%) were of Stage 1; 46 tumors (13.9%) were of Stage 2. Almost all were of Stage 2 due to size alone (≥2 cm); one tumor was "upstaged" due to "high-risk features." Using the NCCN taxonomy, 231 (87%) of tumors were "high-risk." Discussion. This analysis demonstrates discordance between AJCC and NCCN definitions of "high-risk" cSCC. Few cSCCs are of Stage 2 by AJCC criteria, while most are "high-risk" by the NCCN guidelines. While the current guidelines represent significant progress, further studies are needed to generate a unified definition of "high-risk" cSCC to optimize management.

RESUMO

We present the case of a 76-year-old man with gastroduodenal intussusception secondary to a gastric hyperplastic polyp. Intussusception in the adult population occurs infrequently. Our patient presented with gastroduodenal intussusception, which is very uncommon and accounts for <10% of all types of intussusception. This case is unique in that partial endoscopic resection of the gastric hyperplastic polyp resolved the patient's gastroduodenal intussusception, biliary obstruction and biochemical pancreatitis without the need for surgical intervention.
