Project description:BackgroundPostoperative concerns after Mohs micrographic surgery (MMS) are not well characterized.ObjectiveTo better define patient concerns and contributing characteristics in the immediate postoperative period after MMS.Materials and methodsA standardized telephone encounter template was implemented to better assess patient concerns in the 24-hour postoperative period. A review was then performed of patients undergoing MMS from October 2016 to July 2017 to assess for the most common patient concerns and association with clinical characteristics.ResultsWe included 307 patients. Overall, 60.6% of patients reported a concern. Fifty-four percent of patients reported pain. Most pain was characterized as "a little" (67.7%). On univariate analysis, flap repairs, location on the upper extremities, and swelling were associated with higher mean postoperative pain. Tumor type was not associated with increased pain. On multivariate analyses, patients with larger defects and associated edema were statistically significantly associated with higher degrees of pain.ConclusionOver half of patients experience postoperative concerns after MMS, most commonly pain. The immediate postoperative period may be an optimal time to identify patient concerns allowing for reassurance or early intervention when necessary.
Project description:Mohs micrographic surgery (MMS) can lead to complications such as scarring and delayed wound healing, particularly in sensitive areas such as the face, neck, and chest. This study aims to assess the evidence regarding the use of lasers post-MMS for wound healing and scar revision. A comprehensive systematic review of the literature was performed using databases including MEDLINE, PubMed, EMBASE, Web of Science, Cochrane Library, and CINAHL from inception until July 25, 2022. A total of 2147 unique studies were identified, from which 17 were included in the analysis. A total of 17 studies reported applications of lasers with favourable efficacy including wound healing (n = 1), resurfacing of full-thickness skin grafts and split-thickness skin grafts (n = 4), periscar telangiectasias (n = 1), functional scar contractures (n = 2), and scar texture (n = 9). Minimal adverse effects were reported with the use of lasers post-MMS. Overall, the use of lasers post-MMS is a safe and well-tolerated option for scar revision with high patient satisfaction and is less invasive than surgical interventions.
Project description:ImportanceMohs micrographic surgery (MMS) is a skin cancer treatment that uses staged excisions based on margin status. Wide surgeon-level variation exists in the mean number of staged resections used to treat a tumor, resulting in a cost disparity and question of appropriateness.ObjectiveTo evaluate the effectiveness of a behavioral intervention aimed at reducing extreme overuse in MMS, as defined by the specialty society, by confidentially sharing stages-per-case performance data with individual surgeons benchmarked to their peers nationally.Design, setting, and participantsThis nonrandomized controlled intervention study included 2329 US surgeons who performed MMS procedures from January 1, 2016, to March 31, 2018. Physicians were identified using a 100% capture of Medicare Part B claims. The intervention group included physicians affiliated with the American College of Mohs Surgery, and the control group included physicians not affiliated with the American College of Mohs Surgery.InterventionsIndividualized performance reports were delivered to all outlier surgeons, defined by the specialty society as those with mean stages per case 2 SDs above the mean, and inlier surgeons in the intervention group.Main outcomes and measuresThe primary outcome was surgeon-level change in mean stages per case between the prenotification (January 2016 to January 2017) and postnotification (March 2017 to March 2018) periods. A multivariable linear regression model was used to evaluate the association of notification with this surgeon-level outcome. The surgeon-level metric of mean stages per case was not risk adjusted. The mean Medicare cost savings associated with changes in practice patterns were calculated.ResultsOf the 2329 included surgeons, 1643 (70.5%) were male and 2120 (91.0%) practiced in metropolitan areas. In the intervention group (n = 1045), 53 surgeons (5.1%) were outliers; in the control group (n = 1284), 87 surgeons (6.8%) were outliers. Among the outliers in the intervention group, 44 (83%) demonstrated a reduction in mean stages per case compared with 60 outliers in the control group (69%; difference, 14%; 95% CI of difference, -1 to 27; P = .07). There was a mean stages-per-case reduction of 12.6% among outliers in the intervention group compared with 9.0% among outliers in the control group, and outliers in the intervention group had an adjusted postintervention differential decrease of 0.14 stages per case (95% CI, -0.19 to -0.09; P = .002). The total administrative cost of the intervention program was $150 000, and the estimated reduction in Medicare spending was $11.1 million.Conclusions and relevanceSharing personalized practice pattern data with physicians benchmarked to their peers can reduce overuse of MMS among outlier physicians.
Project description:IntroductionNon-melanoma skin cancers (NMSCs) are the most common cancers in the USA, and their incidence is rising. Mohs micrographic surgery (MMS) is commonly performed to excise NMSCs. MMS replaced superficial radiotherapy (SRT) as a first line treatment, given its superior efficacy. Image-guided superficial radiation therapy (IGSRT) was invented to improve the precision of SRT. This study investigates how the 2-year recurrence probability of IGSRT-treated NMSCs compares to that of MMS-treated lesions.MethodsThis retrospective cohort study compared the 2-year recurrence probability of early stage NMSCs (squamous and basal cell carcinomas (SCCs and BCCs)) treated by IGSRT (2,286 lesions) to data on NMSCs treated by MMS (5,391 lesions) via one sample proportion tests. Medical Subject Headings were used to search PubMed for reports of 2-year recurrence probability rates of NMSCs treated by MMS. Seventeen studies were screened; 14 studies were excluded for lack of 2-year time to event analysis, or irrelevant patient population (non-BCC/SCC study, advanced disease), leaving 3 studies for comparison.ResultsIGSRT-treated NMSCs have a statistically significantly improved 2-year recurrence probability than those treated by MMS, P < 0.001 for pooled data.ConclusionThe 2-year recurrence probability IGSRT-treated NMSCs is superior to MMS-treated and supports IGSRT as an effective treatment option for individuals with early stage NMSCs.
Project description:BackgroundThe use of Mohs micrographic surgery (MMS) has increased greatly to treat basal cell and cutaneous squamous cell carcinomas (keratinocyte carcinoma [KC]), and consensus-based Appropriate Use Criteria (AUC) were developed to identify tumors for which MMS is appropriate.ObjectiveWe sought to compare recurrence rates after different treatments in tumors judged appropriate for MMS.MethodsWe used data from an observational prospective cohort study and retrospectively categorized consecutive tumors as appropriate for MMS according to the AUC. Among appropriate tumors, we used survival analyses to compare 5-year recurrence rates after treatments.ResultsAmong tumors appropriate for MMS (N = 1483), adjusted 5-year recurrence rates were 2.9% (range, 1.4-4.3%) after MMS, 5.5% (range, 3.1-7.9%) after excision, 4.0% (range, 0.6-7.2%) after destruction, and 5.9% (range, 1.5-10.2%) after other treatments. In tumors treated only with MMS or excision (the most similar subgroups), the adjusted hazard ratio of 5-year recurrence after MMS was 0.6 (95% confidence interval, 0.3-1.0; P = .06).LimitationsThis study is limited by its uncertain generalizability, lack of randomization, and unmeasured characteristics.ConclusionThe AUC identified tumors for which recurrence would be less common after MMS than after excision, but the absolute difference in recurrence rates was small.
Project description:BackgroundThe use of Mohs micrographic surgery (MMS) in melanoma treatment has divided opinion and evidence-based guidelines are lacking.ObjectivesThis systematic review aimed to analyse clinical outcomes for patients with invasive melanomas treated with Mohs rather than wide local excision (WLE).MethodsEmbase, MEDLINE and Cochrane databases (to 30 August 2023) were searched for studies using Mohs to treat invasive melanoma. Outcomes of interest were local recurrence and death from melanoma.ResultsThirty-five articles involving 41,499 patients with invasive melanoma treated with Mohs were identified. Sixteen studies compared Mohs with WLE and 19 were Mohs-only, non-comparative studies. Patients treated with Mohs differed significantly from those undergoing WLE, in particular Mohs patients were older and had thinner melanomas. Two comparative studies using the same data source reported adjusted hazard ratios for melanoma-specific death and both showed no significant difference between Mohs and WLE-treated patients; 0.87 (95% CI 0.55-1.35) and 1.20 (95% CI 0.71-20.36). There was also no statistically significant difference in local recurrence risk; the unadjusted risk ratio for patients treated with Mohs was 0.46 (95% CI 0.14-1.51 p = 0.20) with moderate heterogeneity (I2 = 62%). No studies reported multivariable analyses for risk of local recurrence. Many studies generated from relatively few and often overlapping data sets have reported the use of Mohs to treat patients with invasive melanoma. Fewer studies were comparative between Mohs and WLE and these reported substantially different baseline risks of recurrence and death from melanoma between the groups. Mohs has generally been used for thinner melanomas in older patients; therefore, comparisons based on univariable analyses are likely to have been misleading.ConclusionsOn the basis of currently available data, it is not possible to reliably assess whether outcomes differ if invasive melanomas with comparable features are treated with Mohs or WLE, and randomized trial evidence will be required for reliable conclusions to be reached.
Project description:ImportancePatient preferences for pain medications after Mohs micrographic surgery are important to understand and have not been fully studied.ObjectiveTo evaluate patient preferences for pain management with only over-the-counter medications (OTCs) or OTCs plus opioids after Mohs micrographic surgery given varying levels of theoretical pain and opioid addiction risk.Design, setting, and participantsThis prospective discrete choice experiment was conducted in a single academic medical center from August 2021 to April 2022 among patients undergoing Mohs surgery and their accompanying support persons (≥18 years). A prospective survey was administered to all participants using the Conjointly platform. Data were analyzed from May 2022 to February 2023.Main outcome and measureThe primary outcome was the pain level at which half of the respondents chose OTCs plus opioids equally to only OTCs for pain management. This pain threshold was determined for varying opioid addiction risk profiles (low, 0%; low-moderate, 2%; moderate-high, 6%; high, 12%) and measured via a discrete choice experiment and linear interpolation of associated parameters (pain levels and risk of addiction).ResultsOf the 295 respondents (mean [SD] age, 64.6 [13.1] years; 174 [59%] were female; race and ethnicity were not considered) who completed the discrete choice experiment, 101 (34%) stated that they would never consider opioids for pain management regardless of the pain level experienced, and 147 (50%) expressed concern regarding possible opioid addiction. Across all scenarios, 224 respondents (76%) preferred only OTCs vs OTCs plus opioids after Mohs surgery for pain control. When the theoretical risk of addiction was low (0%), half of the respondents expressed a preference for OTCs plus opioids given pain levels of 6.5 on a 10-point scale (90% CI, 5.7-7.5). At higher opioid addiction risk profiles (2%, 6%, 12%), an equal preference for OTCs plus opioids and only OTCs was not achieved. In these scenarios, patients favored only OTCs despite experiencing high levels of pain.Conclusion and relevanceThe findings of this prospective discrete choice experiment indicate that the perceived risk of opioid addiction affects the patient's choice of pain medications after Mohs surgery. It is important to engage patients undergoing Mohs surgery in shared decision-making discussions to determine the optimal pain control plan for each individual. These findings may encourage future research on the risks associated with long-term opioid use after Mohs surgery.
Project description:ImportanceMelanoma in situ (MIS) is increasing in incidence, and expert consensus opinion recommends surgical excision for therapeutic management. Currently, wide local excision (WLE) is the standard of care. However, Mohs micrographic surgery (MMS) is now used to treat a growing subset of individuals with MIS. During MMS, unlike WLE, the entire cutaneous surgical margin is evaluated intraoperatively for tumor cells.ObjectiveTo assess the outcomes of patients with MIS treated with MMS compared with those treated with WLE.Design, setting, and participantsRetrospective review of a prospective database. The study cohort consisted of 662 patients with MIS treated with MMS or WLE per standard of care in dermatology and surgery (general surgery, otolaryngology, plastics, oculoplastics, surgical oncology) at an academic tertiary care referral center from January 1, 1978, to December 31, 2013, with follow-up through 2015.ExposureMohs micrographic surgery or WLE.Main outcomes and measuresRecurrence, overall survival, and melanoma-specific survival.ResultsThere were 277 patients treated with MMS (mean [SD] age, 64.0 [13.1] years; 62.1% male) and 385 treated with WLE (mean [SD] age, 58.5 [15.6] years; P < .001 for age; 54.8% male). Median follow-up was 8.6 (range, 0.2-37) years. Compared with WLE, MMS was used more frequently on the face (222 [80.2%] vs 141 [36.7%]) and scalp and neck (23 [8.3%] vs 26 [6.8%]; P < .001). The median (range) year of diagnosis was 2008 (1986-2013) for the MMS group vs 2003 (1978-2013) for the WLE group (P < .001). Overall recurrence rates were 5 (1.8%) in the MMS group and 22 (5.7%) in the WLE group (P = .07). Mean (SD) time to recurrence after MMS was 3.91 (4.4) years, and after WLE, 4.45 (2.7) years (P = .73). The 5-year recurrence rate was 1.1% in the MMS group and 4.1% in the WLE group (P = .07). For WLE-treated tumors, the surgical margin taken was greater for tumors that recurred compared with tumors that did not recur (P = .003). Five-year overall survival for MMS was 92% and for WLE was 94% (P = .28). Melanoma-specific mortality for the MMS group was 2 vs 13 patients for the WLE group, with mean (SD) survival of 6.5 (4.8) and 6.1 (0.8) years, respectively (P = .77).Conclusions and relevanceNo significant differences were found in the recurrence rate, overall survival, or melanoma-specific survival of patients with MIS treated with MMS compared with WLE.
