RESUMEN
BACKGROUND: Although advances have been made in the understanding of recurrence patterns in dermatofibrosarcoma protuberans, the current understanding of disease-specific mortality after surgical management is limited. OBJECTIVE: To understand disease-specific mortality rates associated with dermatofibrosarcoma protuberans treated with wide local excision (WLE) versus Mohs micrographic surgery (MMS). MATERIALS AND METHODS: A systematic literature search was conducted on March 6, 2023, to identify patients treated with MMS or WLE for dermatofibrosarcoma protuberans. RESULTS: A total of 136 studies met inclusion criteria. Overall, the disease-specific mortality rate was not significantly different after treatment with MMS (0.7%, confidence interval [CI] 0.1-1.2, p : 0.016) versus WLE (0.9%, CI 0.6-1.2, p < .001). For recurrent tumors, the MMS treatment group had a statistically significantly lower disease-specific mortality rate (1.0%, CI 0.0-2.0, p 0.046) compared with the WLE treatment group (3.5%, CI 2.0-5.1, p < .001). The mean follow-up for all studies was 57.6 months. CONCLUSION AND RELEVANCE: The authors' meta-analysis suggests there is no substantial difference in disease-specific mortality between MMS and WLE in patients with dermatofibrosarcoma protuberans, except in the case of recurrent tumors, where MMS seems to confer a survival advantage.

BACKGROUND: Mohs micrographic surgery (MMS) is increasingly used to treat cutaneous melanoma. However, it is unclear whether intraoperative immunohistochemistry (IHC) improves surgical outcomes. OBJECTIVE: To determine whether intraoperative IHC during MMS and staged excision is associated with a decreased risk of poor surgical outcomes. MATERIALS AND METHODS: Search of 6 databases identified comparative and noncomparative studies that reported local recurrence after MMS or staged excision with or without IHC for melanoma. Random-effects meta-analysis was used to estimate pooled local recurrence rates, nodal recurrence, distant recurrence, and disease-specific mortality. RESULTS: Overall, 57 studies representing 12,043 patients with cutaneous melanoma and 12,590 tumors met inclusion criteria. Combined MMS and staged excision with IHC was associated with decreased local recurrence in patients with invasive melanoma (0.3%, 95% CI: 0-0.6) versus hematoxylin and eosin alone (1.8%, 95% CI: 0.8%-2.8%) [ p < .001]. Secondary outcomes including nodal recurrence, distant recurrence, and disease-specific mortality were not significantly different between these 2 groups. Study heterogeneity was moderately-high. CONCLUSION: Local recurrence of invasive melanoma is significantly lower after MMS and staged excision with IHC as opposed to without IHC. These findings suggest that the use of intraoperative IHC during MMS or staged excision should strongly be considered, particularly for invasive melanoma.Trial Registration PROSPERO Identifier: CRD42023435630.

BACKGROUND AND OBJECTIVE: Primary cutaneous melanoma incidence is increasing in elderly individuals. This population-based cohort examines incidence and mortality rates among adults aged 61 years and older with cutaneous melanoma. MATERIALS AND METHODS: Using the Rochester Epidemiology Project, patients aged 61 years of age or older with a first lifetime diagnosis of cutaneous melanoma between January 1, 1970 and December 31, 2020 were identified. RESULTS: The age- and sex-adjusted incidence rate increased from 16.4 (95% CI, 8.2-24.6) per 100,000 person-years in 1970 to 1979 to 201.5 (95% CI, 185.1-217.8) per 100,000 person-years in 2011 to 2020 (12.3-fold increase). There was a 16.0x increase in males and an 8.5× increase in females. Melanoma incidence has stabilized in males (1.2-fold increase, p = .11) and continues to significantly increase in females (2.7-fold increase, p < .001). Older age at diagnosis was significantly associated with an increased risk of death (HR 1.23 per 5-year increase in age at diagnosis, 95% CI, 1.02-1.47). CONCLUSION: Melanoma incidence continues to increase since 1970. The incidence has risen in elderly females, but has stabilized in males. Mortality has decreased throughout this period.

BACKGROUND: This study aims to determine the population-based incidence and characterize the features of nonarteritic anterior ischemic optic neuropathy (NAION) using the Rochester Epidemiology Project (REP). METHODS: All patients diagnosed with an optic neuropathy from January 1, 1990, to December 31, 2016, were retrospectively reviewed to identify incident cases of NAION using the REP database, which is a record-linkage system of medical records for all patient-physician encounters among Olmsted County, Minnesota residents. The overall incidence of NAION was estimated using the age-specific and sex-specific population figures for Olmsted County census data for 1990 through 2016. Visual outcomes and risk factors were evaluated. The systemic risk factors were compared with age-matched controls. RESULTS: One hundred four patients were diagnosed with NAION during the 26-year study period. The overall age and sex adjusted incidence was 3.89 per 100,000 individuals (95% confidence interval [CI]: 3.14-4.65). The incidence was 7.73 (CI: 6.24-9.22) in patients aged 40 years or older and 10.19 (CI: 8.15-12.23) in patients aged 50 years or older. Median age at diagnosis was 65 years (range, 40-90 years), and 59 (56.7%) were male. The median logMAR visual acuity at presentation was 0.35 (Snellen equivalent of 20/40) with 14 patients (13.5%) having vision of counting fingers or worse. Among the 91 patients with final visual acuity outcome data available, the median visual acuity was 0.40 (Snellen equivalent of 20/50) with 12 patients (13.2%) having vision of counting fingers or worse. Twenty-four patients (26.4%) were noted to have final acuity at least 3 Snellen lines worse than at presentation, whereas 17 patients (18.7%) were noted to improve by at least 3 lines. The median mean deviation on automated visual field testing was -10.2 dB at presentation and -11.1 dB at follow-up. Twenty-two patients (21.2%) suffered NAION in the fellow eye; the median interval between involvement of the first and second eyes was 1.39 years. Systemic diseases present in the NAION cohort included hypertension (79.8%), diabetes mellitus (39.4%), obstructive sleep apnea (23.1%), and hyperlipidemia (74.0%), which were all statistically higher than age-matched controls. CONCLUSIONS: NAION is a relatively common optic neuropathy in elderly patients with vascular risk factors. Our data indicate that the incidence of NAION has remained relatively stable in the population of Olmsted County over the past 4 decades.

BACKGROUND: Current consensus guidelines have discouraged the use of sub-0.5-cm (in situ) and sub-1-cm (invasive) margins when performing Mohs micrographic surgery (Mohs) for melanoma, with minimal evidence to guide this recommendation. OBJECTIVE: To compare melanoma local recurrence rates after Mohs based on initial margin size. MATERIALS AND METHODS: A systematic review and meta-analysis was conducted with search terms including Mohs micrographic surgery, surgical margin, recurrent disease, and melanoma. RESULTS: Forty-three studies were included. The 5- to 10-mm margin category had a statistically significant lower local recurrence compared with 1- to 5-mm and 5-mm categories. Recurrence for 1- to 5-mm, 5-mm, 5- to 10-mm, and 10-mm categories were 2.3% (CI 0.8-3.5, p < .001), 1.4% (CI 0.6-2.2, p < .001), 0.3% (CI 0.2-0.5, p < .001), and 6.1% (CI -6.7 - 18.8, p = .349), respectively. Number of stages for 1 to 5, 5, 5 to 10, and 10-mm categories were 1.8, 1.8, 1.6, and 1.6, respectively. There was no statistically significant difference between the groups (p = .694). CONCLUSION: Five- to 10-mm margins were associated with the lowest local recurrence rates. A 5- to 10-mm initial margin should be considered where other factors (tumor characteristics, anatomical or functional considerations) allow.

BACKGROUND: Nonarteritic anterior ischemic optic neuropathy (NAION) is a common cause of acute optic neuropathy in adults and is associated with vascular risk factors. Owing to the overlapping risk factor profiles between NAION and cerebral stroke, previous studies have produced conflicting results with regard to NAION as an independent risk factor for stroke. METHODS: A retrospective chart review was conducted using the Rochester Epidemiology Project database to identify all cases of NAION occurring among Olmsted County, Minnesota residents from January 1, 1990, through December 31, 2016. Stroke events were characterized using clinical and radiologic data. Comparison was made to an age- and sex-matched control group with similar vascular risk factors. RESULTS: One-hundred four patients with NAION and 104 control subjects were analyzed. Median age at diagnosis was 65 years (range, 40-90 years). Thirteen patients (13%) with NAION and 10 controls (10%) had symptomatic strokes after the age of 40 years. Among patients with NAION, 6 (46%) suffered a stroke before the diagnosis of NAION, 5 (39%) at least 5 months after the NAION diagnosis, and 2 patients (15%) suffered strokes both before and after the NAION. The cumulative probability of symptomatic strokes for patients with NAION was not significantly different than for controls (hazard ratio = 1.50, 95% confidence interval: 0.66-3.42; P = 0.34). There were no cardioembolic strokes within 1 month of the NAION diagnosis. The mechanism of symptomatic strokes did not differ between the 2 groups. CONCLUSIONS: NAION does not confer an increased risk of symptomatic stroke beyond the risk posed by age and existing vascular risk factors.

Background: National cancer reporting-based registry data, although robust, lacks granularity for incidence trends. Expert opinion remains conflicted regarding the possibility of melanoma overdiagnosis in the context of rising incidence without a corresponding rise in mortality. Objective: To characterize 10- and 50-year trends in melanoma incidence and mortality. Methods: Multicenter, population-based epidemiologic study utilizing the Rochester Epidemiology Project for Olmsted County, Minnesota residents diagnosed with melanoma from 01/01/1970 to 12/21/2020. Age- and sex-adjusted incidence and disease-specific mortality are calculated. Results: Two thousand three hundred ten primary cutaneous melanomas were identified. Current age- and sex-adjusted incidence rates increased 11.1-fold since 1970s (P < .001). Over the last decade, there is an overall 1.21-fold (P < .002) increase, with a 1.36-fold increase (P < .002) among females and no significant increase among males (1.09-fold increase, P < .329). Melanoma-specific mortality decreased from 26.7% in 1970s to 1.5% in 2010s, with a hazard ratio (HR) reduction of 0.73 (P < .001) per 5-year period. Increased mortality was associated with Breslow thickness (HR 1.35, P < .001), age at diagnosis (HR 1.13, P = .001) left anatomic site (HR 1.98, P = .016), and nodular histogenic subtype (HR 3.08, P < .001). Limitations: Retrospective nature and focused geographic investigation. Conclusion: Melanoma incidence has continued to increase over the past decade, most significantly in females aged 40+. Trend variations among age and sex cohorts suggests external factors beyond overdiagnosis may be responsible. Disease-specific mortality of melanoma continues to decrease over the last 50 years.
RESUMEN
Background: During Mohs surgery for melanoma, evidence has demonstrated that many surgeons opt for smaller initial margins than traditionally recommended (0.5 cm for in situ and 1 cm for invasive). Literature regarding surgical outcomes based on initial margin is sparse. Objective: To determine differences in disease-specific survival of melanoma after Mohs micrographic surgery for varied initial surgical margins. Methods: A literature search was conducted on February 14, 2022, from MEDLINE via PubMed (1946-present), Embase (1974-present), Central (1991-present), and Scopus (1960-present). The primary outcome was disease-specific mortality. Results: Nineteen studies were included for final analysis. The overall disease-specific mortality rate of melanoma in all included studies was 0.5% (CI, 0.1-0.8; P, .010). Disease-specific mortality for 1 to 5, 5, and 6 to 10 mm categories were 0.4% (CI, 0.0-0.9; P, .074), 0.7% (CI, 0.2-1.3; P, .2-1.3), and 0.4% (CI, -0.9 to 1.8; P, .524), respectively. None of the variances across initial margin categories were statistically significant. Limitations: Early-stage melanomas have low overall mortality rates. In our associated article, initial margins of 5 to 10 mm were shown to have the lowest rates of local recurrence. Conclusions: In this systematic review and meta-analysis, melanoma-specific mortality was not significantly impacted by the initial surgical margin taken during Mohs micrographic surgery.
RESUMEN
OBJECTIVE: To identify changes in the incidence and mortality of cutaneous melanoma in the fastest-growing segment of the US population, middle-aged adults. PATIENTS AND METHODS: Using the Rochester Epidemiology Project, patients aged 40 to 60 years with a first lifetime diagnosis of cutaneous melanoma between January 1, 1970, and December 31, 2020, while a resident of Olmsted County, Minnesota, were identified. RESULTS: A total of 858 patients with a primary cutaneous first-time melanoma were identified. The overall age- and sex-adjusted incidence rate increased from 8.6 (95% CI, 3.9 to 13.3) per 100,000 person-years in 1970-1979 to 99.1 (95% CI, 89.5 to 108.7) per 100,000 person-years in 2011-2020 (11.6-fold increase). There was a 52.1-fold increase in women and a 6.3-fold increase in men between these 2 periods. In recent years (2005-2009 vs 2015-2020), the incidence has stabilized in men (1.01-fold increase; P=.96) and continues to significantly increase in women (1.5-fold increase; P=.002). Among 659 patients with invasive melanoma, 43 deaths were due to melanoma, and male sex was significantly associated with an increased risk of death (hazard ratio, 2.95; 95% CI, 1.45 to 6.00). A more recent diagnosis of melanoma was significantly associated with a decreased risk of death due to melanoma (hazard ratio, 0.66 per 5-year increase in calendar year of diagnosis; 95% CI, 0.59 to 0.75). CONCLUSION: Melanoma incidence has significantly increased since 1970. During the past 15 years, the incidence has continued to rise in middle-aged women (approximately 50% rise in incidence) but has stabilized in men. Mortality decreased in a linear fashion throughout this time.

Importance: The study of health conditions associated with papilledema will augment the clinical judgment of eye care professionals treating patients with optic disc edema in determining the urgency of additional evaluation and counseling patients accordingly. Objectives: To determine the incidence, demographic characteristics, and etiologies of papilledema based on a unique records-linkage research platform; and to describe the demographic and clinical differences between patients with idiopathic intracranial hypertension (IIH) and other causes of papilledema. Design, Setting, and Participants: Retrospective population-based cross-sectional study of patients treated for papilledema at outpatient eye clinics in Olmsted County, Minnesota, using the Rochester Epidemiology Project. Data were collected from January 1990 to December 2014 and analyzed from September 2018 to April 2019. Main Outcomes and Measures: Etiologies of papilledema, body mass index, incidence of headache, or localizing neurologic signs. Results: Eighty-six patients were diagnosed with papilledema during the 24-year period, providing an age- and sex-adjusted incidence of 2.5 individuals per 100â¯000 per year; 68 patients (79%) were women, 73 (85%) were white patients, and the median (range) age was 27.7 (6.2-64.2) years. Nineteen patients (22%) presented with a previously diagnosed attributable cause (eg, trauma or intracranial tumor). Among patients presenting with papilledema without a previously diagnosed attributable cause, 58 patients (87%) had IIH, and 9 patients (13%) were found to have a secondary cause of raised intracranial pressure, such as intracranial tumor, cerebral venous sinus thrombosis, or granulomatous meningitis. Patients with IIH had a higher median (range) body mass index (37.5 [20.4-55.7] vs 27.4 [16.6-40.1]; P = .003) and headache prevalence (54 of 58 patients [93%] vs 6 of 9 patients [67%]; P = .004) than patients with other causes of papilledema. Of 9 patients with papilledema but no IIH, 2 (22%) had localizing neurologic signs, such as gait abnormalities, hearing loss, focal weakness or numbness, visual field defects, or aphasia. Among 42 patients with demographic characteristics typically associated with IIH (female sex, with obesity, aged 15 to 45 years, and absent localizing neurologic signs or symptoms), 40 (95%) had papilledema that was associated with IIH. Conversely, among the 19 patients without these demographic characteristics, 7 (37%) had an alternative cause. Conclusions and Relevance: In this study, most patients who presented to the eye clinic with papilledema without a previously known cause were found to have IIH. These patients were more likely to present with headaches and had statistically higher body mass index. Clinicians should take these findings into account when determining the pretest probability of a patient having IIH or an alternative cause of papilledema.
