FACE-Q for Measuring Patient-reported Outcomes after Facial Skin Cancer Surgery: Cross-cultural Validation

Background

Facial skin cancer and its surgical treatment can affect health-related quality of life. The FACE-Q Skin Cancer Module is a patient-reported outcome measure that measures different aspects of health-related quality of life and has recently been translated into Dutch. This study aimed to evaluate the performance of the translated version in a Dutch cohort using modern psychometric measurement theory (Rasch).

Methods

Dutch participants with facial skin cancer were prospectively recruited and asked to complete the translated FACE-Q Skin Cancer Module. The following assumptions of the Rasch model were tested: unidimensionality, local independence, and monotonicity. Response thresholds, fit statistics, internal consistency, floor and ceiling effects, and targeting were assessed for all scales and items within the scales. Responsiveness was tested for the "cancer worry" scale.

Results

In total, 259 patients completed the preoperative questionnaire and were included in the analysis. All five scales assessed showed a good or sufficient fit to the Rasch model. Unidimensionality and monotonicity were present for all scales. Some items showed a local dependency. Most of the scales demonstrate ordered item thresholds and appropriate fit statistics.

Conclusions

The FACE-Q Skin Cancer Module is a well-designed patient-reported outcome measure that shows psychometric validity for the translated version in a Dutch cohort, using classical and modern test theory.

Family Planning Experiences and Challenges of Mohs Fellowship Trainees

BACKGROUND

There is a paucity of literature describing family planning challenges faced by Mohs fellows.

OBJECTIVE

To characterize perceptions about and experiences with family planning, fertility, lactation, and parental leave and identify ways to support parental health and family planning for Mohs fellows.

MATERIALS AND METHODS

A voluntary, anonymous survey was distributed to Mohs surgeons who recently completed fellowship.

RESULTS

In total, 116 Mohs surgeons completed the survey. Their mean age was 34.5 years old, and more were female ( n = 81, 69.8%) than male ( n = 35, 30.2%). Most had children before completion of their Mohs training ( n = 73, 62.9%). The most significant barrier to having children during fellowship was "loss of education or training time." Over 20% ( n = 23) of respondents or their partner had experienced infertility. Half of the 20 respondents ( n = 10) who breastfed or pumped did not have a convenient place to do so.

CONCLUSION

This study elucidates trainee perceptions and gaps in parental support for Mohs fellowship trainees. In addition, barriers to implementing a universal family planning policy in Mohs surgery are discussed.

Patient Satisfaction Following Primary Closure or Second Intention Healing After Conventional Nasal Skin Cancer Excision: A Cross-sectional Cohort Study

BACKGROUND

Nasal reconstruction after conventional surgical excision (CSE) of nonmelanoma skin cancer (NMSC) can be challenging. After excision and before the pathologic report, a simple reconstruction is favored. Yet, little is known about patient satisfaction after primary closure and second intention healing.

OBJECTIVE

Patient satisfaction after nasal defect reconstruction with primary closure or second intention healing, using the FACE-Q Skin Cancer.

METHODS

All patients who underwent CSE of nasal NMSC with immediate primary closure or second intention healing between March 2018 and March 2020 at Máxima Medisch Centrum Veldhoven were identified and asked to complete the FACE-Q Skin Cancer.

RESULTS

Of 183 patients, 140 patients completed the questionnaire. Fifty-five defects were closed by primary closure (38.5%) and 88 by second intention healing (61.5%). Thirty-one complications were reported (16.7%), of which 87.1% ( n = 27) after second intention healing ( p = .004). Both groups experienced high facial and scar satisfaction, low appearance-related distress, and no to minimal adverse effects. Second intention healing had 2.7 higher odds of achieving the maximum scar satisfaction score ( p = .02).

CONCLUSION

This study shows high satisfaction on facial and scar appraisal, low appearance-related distress, and no to minimal adverse effects for second intention healing and primary closure after CSE of nasal NMSC.

Oesophagopleural fistula after pneumonectomy: A systematic review and case series

INTRODUCTION

There is a paucity of data on the optimal management of oesophagopleural fistula (OPF) following pneumonectomy. The current published literature is limited to case reports and small case series. Although rare, OPF can have a significant impact on both the morbidity and mortality of patients.

METHODS

Two cases of OPF managed at our institution were reported. A systematic review was then conducted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance concerning OPF following pneumonectomy. Demographic, operative and management data were analysed.

FINDINGS

Systematic review-identified data pertaining to 59 patients from 31 papers was collated. Median patient age was 59.5 years with pneumonectomy performed typically for malignancy (68%) or tuberculosis (19%). Median time from pneumonectomy to a diagnosis of OPF was 12.5 months. Twenty-five per cent of the patients had a synchronous bronchopleural fistula. Management of OPF in this setting is heterogenous. Conservative management was often reserved for asymptomatic or unfit patients. The remainder underwent endoscopic or surgical correction of the fistulae or a combination of the two with varying outcomes. Median follow-up was 18 months. All-cause mortality was 31% (18/59) with a median duration from pneumonectomy to death of 35 days (range 1-1,095).

CONCLUSIONS

Major heterogeneity of management for this rare complication hinders the introduction of standardised guidance of post-pneumonectomy OPF. Surgical and endoscopic intervention is feasible and can be successful in specialist centres. Adopting an multidisciplinary team approach involving both oesophagogastric and thoracic surgery teams and the introduction of a registry database of postoperative complications are likely to yield optimal outcomes.

Intrahospital transmission and infection control of Candida auris originating from a severely infected COVID-19 patient transferred abroad

BACKGROUND

Intrahospital spread of Candida auris, which survives tenaciously in many environments, can cause sustained colonization and infection. A large outbreak of C. auris was experienced in the intensive care units (ICUs) at the study hospital during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

The index patient with severe COVID-19, who was transferred from Vietnam in January 2022, developed C. auris candidaemia 10 days after hospitalization. From mid-June 2022 to January 2023, strengthened infection prevention and control (IPC) measures were implemented in three ICUs: (1) contact precautions and isolation (CPI) for C. auris-positive cases; (2) surveillance cultures including point-prevalence (N=718) for patients or close contacts or ICU-resident healthcare workers (HCWs); (3) intensive environmental disinfection with 10-fold diluted bleach; and (4) 2% chlorhexidine bathing for all ICU patients. Environmental cultures (ECx) on surfaces and shared objects (N=276) were conducted until early September 2022, when all ECx were negative.

RESULTS

Among 53 C. auris-positive patients between February 2022 and January 2023, invasive infections resulted in seven cases of candidaemia and one case of pneumonia. C. auris was isolated from reusable tympanic thermometers (TTMs) contaminated with earwax. The isolation rate of C. auris in ECx decreased from 6.8% in June 2022 to 2.0% in August 2022, and was no longer detected in TTMs. Colonization in HCWs was remarkably rare (0.5%). The number of C. auris-positive patients peaked in July (N=10) then decreased gradually. By January 2023, no C. auris were isolated in the ICU.

CONCLUSION

Aggressive IPC measures with CPI, ECx and surveillance, decontamination of TTMs, and bathing were effective in successfully controlling this C. auris outbreak.

Quality of Life Before and After Radiation Therapy for Early-Stage Keratinocyte Carcinoma: A Longitudinal Analysis

PURPOSE

Little is known about patient-reported quality of life (QOL) before and after radiotherapy (RT) for early keratinocyte carcinoma (KC). The present study tested the hypothesis that QOL is hypothesized to deteriorate soon after RT, with subsequent improvement of a magnitude similar to other KC treatments.

METHODS AND MATERIALS

This observational study assessed prospectively collected longitudinal patient-reported QOL data at a single center. Patients undergoing external beam RT for early-stage (T0-2, <4 cm) KC that completed the Skindex-16 (S16) or Skin Cancer Index (SCI) before and at least once after RT were included. These indices include subscales of symptoms, emotions, and functioning for S16 and emotional, social, and appearance for SCI.

RESULTS

81 patients (median age 79 years) were treated for early KC, most being basal cell carcinomas (87%) on the face (80%) an average of 1.3 cm in diameter. Composite S16 scores and total SCI scores showed significant, clinically meaningful improvements at 3 months and 6 weeks after RT, respectively. QOL declined at 6 weeks after treatment on the S16 symptoms subscale. Concurrently, S16 and SCI emotional subscales significantly improved, and this trend persisted for 2+ years. Improvements in S16 functioning and SCI social and appearance QOL occurred after RT. The magnitude of improvement in QOL 3-12 months after RT was comparable to what has been previously reported after other types of KC treatments, like surgery.

CONCLUSIONS

QOL related to symptoms deteriorates during the first 6 weeks after RT for early KC, but it improves by 3 months. QOL related to emotions, functioning, social, and appearance all improve after RT. These changes in QOL are similar to those observed after other treatments of early KC.

Quality of Life Before and after Radiotherapy for Early-Stage Keratinocyte Carcinoma: A Longitudinal Analysis

PURPOSE/OBJECTIVE(S)

Cutaneous squamous and basal cell carcinoma (keratinocyte carcinoma, KC) are common malignancies treated with radiotherapy (RT) to preserve form and function. Treatment of KC can compromise quality of life (QOL), but little is known about patient-reported QOL before and after RT for early KC. The purpose of this study was to assess prospectively collected patient-reported QOL before and after RT for early KC and compare this to previously reported studies of other treatments. It was hypothesized that QOL deteriorates soon after RT, with subsequent improvement of a magnitude similar to previously published reports of other KC treatments.

MATERIALS/METHODS

Patients undergoing RT for early-stage (T0-2, <4 cm) KC who completed a QOL assessment before and at least once after RT were the subjects of study. Characteristics of patients, tumors and treatment were recorded. Patient-reported QOL was measured by 2 validated indices: Skindex-16 (S16, including subscales of symptoms, emotions, functioning; lower score is better QOL) and Skin Cancer Index (SCI, including emotional, social and appearance subscales; higher score is better QOL). Paired t-tests compared scores before and at 4 time points after treatment (6 weeks, 3 months, 1 and 2+ years), with a ≥10-point difference considered clinically significant, and a p<0.0125 considered statistically significant due to Bonferroni correction.

RESULTS

A total of 85 patients (median age 79 years) with early KC, most of which were basal cell carcinomas (87%) on the face (80%) and an average of 1.3 cm in diameter were treated with a median of 48 Gy in 12 fractions. Composite S16 scores and total SCI scores showed significant, clinically meaningful improvements 3 months (15.2→5.2) and 6 weeks (72.0→85.7) after RT. Non-significant declines in QOL happened 6 weeks after treatment on the S16 symptom subscale (11.3→16.6). Concurrently, S16 and SCI emotional subscales (25.9→14.4 and 67.2→79.3) significantly improved, and this trend persisted for 2+ years. Improvements in S16 functioning (8.7→2.8) and SCI social (80.2→89.6) and appearance (68.6→90.5) QOL occurred. S16 demonstrated that 1-2 years after treatment, composite QOL improved by 45%, 47%, 39% and 10% in patients treated with RT, Mohs surgery, excision and electrodessication and curettage, respectively. SCI demonstrated that 3-4 months after treatment, total QOL improved by 24% and 4-13% after RT and Mohs surgery, respectively.

CONCLUSION

QOL related to symptoms deteriorates at 6 weeks after RT, with clinically and statistically significant improvement seen by 3 months after RT. QOL related to emotions, functioning, social and appearance domains all improve after RT. The changes in QOL are similar if not greater than those observed after other treatments of early KC, and may help guide patient expectations following RT.

Association of body mass index and bloodstream infections in patients on extracorporeal membrane oxygenation: a single-centre, retrospective, cohort study

BACKGROUND

Obesity is associated with poor clinical outcomes in critically ill patients. However, under some clinical conditions, obesity has protective effects. Bloodstream infections (BSI) are among the most common nosocomial infections associated with extracorporeal membrane oxygenation (ECMO). BSI during ECMO is associated with higher mortality rates and poorer clinical outcomes.

AIM

To analyse whether body mass index (BMI) is associated with BSI during ECMO or with in-hospital mortality.

METHODS

All adult patients who had received ECMO support for >48 h were included in the analysis. The analysis of total duration of ECMO support, in-hospital mortality and BSI was stratified by BMI category. The Cox proportional hazards model was used to compare the risk of BSI among BMI categories.

FINDINGS

In total, 473 patients were enrolled in the study. The average age was 56.5 years and 65.3% were men. The total duration of ECMO was approximately 11.8 days, with a mortality rate of 47.1%. The incidence rates of BSI and candidaemia were 20.5% and 5.5%, respectively. The underweight group required ECMO for respiratory support, whereas the overweight and obese groups required ECMO for cardiogenic support (P<0.0001). No significant difference in BSI rate was found (P=0.784). However, after adjusting for clinical factors, patients in Group 4 (BMI 25.0-<30.0 kg/m2) exhibited lower mortality compared with patients in Group 2 (normal BMI) (P=0.004).

CONCLUSION

BMI was not associated with risk of BSI, but patients with higher BMI showed lower in-hospital mortality associated with ECMO support.

A systematic review of patient-reported outcome measures for advanced skin cancer patients

Many patient-reported outcome measures (PROMs) have been used to study quality of life (QOL) in the skin cancer population. Advanced melanoma and non-melanoma skin cancer (NMSC) may be associated with increased morbidity, mortality, and treatment side effects; however, it is unclear which PROM is valid and appropriate to use in these populations for both clinical and research purposes. We aimed to identify the PROMs that have been used to measure QOL in advanced skin cancer patients and determine which of these PROMs have been validated to assess QOL outcomes in this population. A PubMed and EMBASE search was conducted from its inception to March 2021 according to PRISMA guidelines with a comprehensive list of search terms under three main topics: (1) PROM; (2) advanced skin cancer; and (3) staging and interventions. We included articles utilizing a PROM measuring QOL and having a patient population with advanced skin cancer defined as melanoma stage > T1a or non-melanoma AJCC stage T3 or greater. Advanced skin cancer patients were also defined as those with metastasis or requiring adjuvant therapy (systemic chemotherapy, radiation, and immunotherapy). Studies were excluded according to the following criteria: mix of low-risk and advanced skin cancer patients in the study population without stratification into low-risk and advanced groups, stage T1a melanoma or mix of stages without stratification, low-risk NMSC, no PROM (i.e., study specific questionnaires), non-English publication, review article or protocol paper, conference abstract, or populations including non-skin cancers. A total of 1,998 articles were identified. 82 met our inclusion criteria resulting in 22 PROMs: five generic health-related (QWB-SA, AQoL-8D, EQ-5D, SF-36, and PRISM), six general cancer (EORTC QLQ-C30, EORTC QLQ-C36, LASA, IOC, Rotterdam Symptom Checklist, and FACT-G), nine disease-focused or specialized (EORTC QLQ-H&N35, EORTC QLQ-MEL38, EORTC QLQ-BR23, Facial Disability Index, FACT-H&N, FACT-BRM, FACT-B, FACT-M, and scqolit), and two general dermatology (Skindex-16 and DLQI) PROMs. All PROMs have been generally validated except for EORTC QLQ-MEL38. Only two PROMs have been validated in the advanced melanoma population: FACT-M and EORTC QLQ-C36. No PROMS have been validated in the advanced NMSC population. The PROMs that were validated in the advanced melanoma population do not include QOL issues unique to advanced skin tumors such as odor, bleeding, itching, wound care burden, and public embarrassment. Breast cancer and head and neck cancer instruments were adapted but not validated for use in the advanced skin cancer population due to the lack of an adequate instrument for this population. This study highlights the need for PROM instrument validation or creation specifically geared toward the advanced skin cancer population. Future studies should aim to develop and validate a PROM to assess QOL in this population.

Staging System Performance and Clinical Outcomes for Cutaneous Squamous Cell Carcinoma of the Ear: A Single-Center Retrospective Study

BACKGROUND

Cutaneous squamous cell carcinoma (cSCC) of the ear is associated with poor outcomes. No studies have evaluated current staging system performance in this specific location.

OBJECTIVE

Describe clinicopathologic characteristics and outcomes of ear cSCC and evaluate the performance of current staging systems.

METHODS

Retrospective study including cases diagnosed and treated at a cancer center from January 2000 to December 2014. Demographic, clinical, and pathologic data were collected from clinical records. Biopsy slides were rereviewed and patients were staged according to the American Joint Committee on Cancer (AJCC) seventh, eighth, and Brigham Women's Hospital (BWH) staging.

RESULTS

Of 125 patients, the mean age at diagnosis was 71.9 years (SD 12.5), with most men (89.6%, n = 112). Median follow-up was 22.3 months. Local recurrence and survival risk factors were similar to cSCC outside the ear. The Akaike's Information Criterion (AIC) estimates showed that the BWH system better predicted outcomes than the AJCC seventh, and the AJCC eighth, with AIC values of 189.9, 270.5, and 274.1, respectively. Limitations of the study include retrospective design, single center study, and no control group.

CONCLUSION

Current staging systems perform well at stratifying risk in ear cSCC.

A Multicenter Prospective Trial of Electronic Skin Surface Brachytherapy for Keratinocyte Carcinoma: Early Cosmesis, Quality of Life, and Adverse Events

PURPOSE

Keratinocyte carcinomas are amenable to many treatments, including radiation therapy (RT). Electronic skin surface brachytherapy (ESSB) enables the precise delivery of radiation without radioisotopes. In this prospective multicenter clinical trial, we characterized early outcomes of ESSB prospectively through both patient- and clinician-reported measures. To corroborate the cosmesis observations, we also assessed patient-reported quality of life (QoL) and adverse events.

METHODS AND MATERIALS

Patients ≥60 years old with stage T1N0M0 keratinocyte carcinoma were treated with ESSB. At 2-, 6-, and 12-weeks post-treatment, cosmesis from ESSB was assessed by both the patient and a clinician study investigator as either "good," "fair," or "bad." The Skindex-16 and the Skin Cancer Index (SCI) were used to assess patient QoL before and after treatment. Adverse events were assessed using the Common Toxicity Criteria for Adverse Events, version 4.0.

RESULTS

Cosmesis and QoL were collected at 97% (99/102) of possible patient follow-up times. By 12 weeks post-treatment, 93.9% (31/33) of patient-reported and 96.9% (31/32) of clinician-reported cosmesis outcomes were "good." Compared with baseline, total Skindex-16 score significantly deteriorated at 2 weeks post-treatment (10.5 vs 24.5, P <.001), but significantly improved at 6 weeks (10.5 vs 4.7, P = .014) and 12 weeks (10.5 vs 2.1, P = .001) post-treatment. The total SCI score significantly improved from baseline to 6 weeks (78.4 vs 89.0, P = .001) post-treatment. The most frequent adverse events were radiation dermatitis, skin pain, and pruritus. All adverse events resolved to Grade ≤1 by 12 weeks post-treatment.

CONCLUSIONS

This prospective, multicenter study demonstrated that ESSB is associated with a high rate of "good" early patient-reported cosmesis and increasing QoL and satisfaction with time. Validated assessments demonstrated a significant improvement in quality of life and resolution of moderate early adverse events by 6 to 12 weeks after treatment and corroborate the observation of favorable cosmesis.

Feasibility and Caregiver Receptiveness to Anxiety Screening in Pediatric Cardiology Clinic: A Pilot Study

Children with chronic medical conditions, including heart disease, have increased susceptibility to behavioral health concerns. We sought to evaluate the feasibility and parental opinion of anxiety screening in pediatric cardiology clinic. The PROMIS Pediatric Anxiety v2.0 Short Form 8a (PA2-S8) questionnaire was administered to 48 patients presenting to pediatric cardiology clinic for follow-up care. Parents/caregivers were asked their opinion on anxiety screening in cardiology clinic. The survey was completed by 47 out of 48 participants (median age 13, range 9-17). Fourteen (30%) participants had scores suggestive of increased anxiety symptomatology. No trends were identified between PA2-S8 score and age at diagnosis (P = .13), age at survey administration (P = .28), number of lifetime procedures (P = .89), number of noncardiac specialists (P = .13), or underlying cardiac diagnoses (P = .55). Most families (76%) were in favor of the screening effort. This study suggests that anxiety screening in cardiology clinic is both feasible and well-received by families.

Appearance-related psychosocial distress after facial non-melanoma skin cancer surgery: A 1-year prospective study

OBJECTIVE

Patients undergoing Mohs Micrographic Surgery (MMS) for facial non-melanoma skin cancer (NMSC) experience appearance-related psychosocial distress due to its post-surgical esthetic changes. However, little is known about its development over a longer follow-up period. This study prospectively assessed appearance-related psychosocial distress in patients undergoing MMS for facial NMSC over a 1-year follow up period.

METHODS

Patients who had MMS for facial NMSC between September 2020 and October 2021 were invited to answer the FACE-Q Skin Cancer - appearance-related psychosocial distress scale preoperatively, 2 weeks, 6 months, and 1 year after surgery.

RESULTS

A total of 217 patients completed the questionnaire at baseline. In addition, 158 (72.8%), 139 (64.1%), and 120 (55.3%) questionnaires were successfully answered 2 weeks, 6 months, and 1 year after surgery, respectively. Patients with a peripheral lesion presented higher appearance-related psychosocial distress scores at baseline than patients with a central lesion (p = 0.02). There was a decreasing trend in appearance-related psychosocial distress over time, but without a significant result (baseline-2-week; p = 0.73, 2-week-6-month; p = 0.80, 6-month-1-year; p = 0.17, baseline-1-year; p = 0.23). Patients with secondary intention healing and graft reconstruction methods experienced more appearance-related psychosocial distress over time than patients with primary wound closures (p = 0.03).

CONCLUSIONS

Patients still experience appearance-related psychosocial distress 1 year after MMS. These patients may benefit from targeted counseling. Additionally, predictors of more appearance-related psychosocial distress, such as secondary intention healing and graft reconstruction methods, may benefit from additional psychological care.

Ergonomic and psychosocial risk factors associated with work-related musculoskeletal disorders in Mohs histotechs

Mohs histotechs are at high risk for work-related musculoskeletal disorders (WRMSDs) due to repetitive motions, forceful exertions, and fixed postures required for their work. Psychosocial factors such as perceptions of pressure to achieve deadlines may exacerbate risk of occupational injury. To assess the prevalence of and risk factors for WRMSD in Mohs histotechs, an online survey was created using literature review, expert opinion, and two validated instruments (the Nordic Musculoskeletal Questionnaire and the Oldenburg Burnout Inventory) and distributed to Mohs histotechs. 88% of respondents reported musculoskeletal problems in 2 or more of the 9 body sites assessed in the past year. Standing during specimen processing was correlated with having neck pain and upper back pain, while sitting was protective against lower back pain. Individuals that felt that they could not take breaks or slow their pace of work were more likely to report pain at multiple body sites. Total pain scores were significantly lower in those reporting extensive ergonomic training. There is a high prevalence of WRMSD in Mohs histotechs. Addressing poor posture as well as psychosocial risk factors could further reduce injury.

Efficacy of a digital mental health intervention embedded in routine care compared with treatment as usual in adolescents and young adults with moderate depressive symptoms: protocol for randomised controlled trial

INTRODUCTION

There are unmet mental health needs of depressed adolescents and young adults (AYAs) across the USA. Behavioural technology adequately integrated into clinical care delivery has potential to improve care access and efficiency. This multisite randomised controlled trial evaluates how a coach-enhanced digital cognitive behavioural intervention (dCBI) enhances usual care for depressed AYAs in paediatric practices with minority enriched samples.

METHODS AND ANALYSIS

Participants (n=750) ages 16-22 who meet threshold criteria for depressive severity (Patient Health Questionnaire-9; PHQ-9 score 10-24) will be recruited through paediatric practices across three academic institutions (Boston, Pittsburgh and San Diego). Participants will be randomised to 12 weeks of dCBI+treatment as usual (TAU) (n=450) or TAU alone (n=300) in outpatient paediatric practices. Assessments will be completed at baseline, 6 weeks and 12 weeks with the primary outcome being improvement in clinician-rated and self-reported depressive severity (Children's Depression Rating Scale-Revised and PHQ-9) and secondary outcomes being self-reported suicidal ideation (item 9 on PHQ-9), anxiety severity (Generalised Anxiety Disorder), general quality of life (Satisfaction with Life Scale) and general functioning (Children's Global Assessment Scale). The study design is an intent-to-treat mixed effects regression with group, and covariates nested within the sites.

ETHICS AND DISSEMINATION

All participants or their parent/guardian (under 18 years or unemancipated) will give informed consent to a study team member. All data are expected to be collected over 18 months. The Institutional Review Board (IRB) is a board at each institution in the United States that reviews and monitors research involving human subjects. IRB approval from the University of Pittsburgh was obtained on 30 November 2021 (STUDY21080150), from the University of California San Diego's Human Research Protection Program IRB on 14 July 2022 (802047), and from the Boston Children's Hospital IRB on 25 October 2022 (P00040987). Full study results are planned to be published within 2 years of initial study recruitment (October 2024). Dissemination of findings will occur in peer-reviewed journals, professional conferences and through reports to participating entities and stakeholders.

Lentigo maligna melanoma mapping using reflectance confocal microscopy correlates with staged excision: A prospective study

BACKGROUND

Lentigo maligna/lentigo maligna melanoma (LM/LMM) can present with subclinical extension that may be difficult to define preoperatively and lead to incomplete excision and potential recurrence. Preliminarily studies have used reflectance confocal microscopy (RCM) to assess LM/LMM margins.

OBJECTIVE

To evaluate the correlation of LM/LMM subclinical extension defined by RCM compared with the gold standard histopathology.

METHODS

Prospective study of LM/LMM patients referred for dermatologic surgery. RCM was performed at the clinically defined initial surgical margin followed by margin-controlled staged excision with paraffin-embedded tissue, and histopathology was correlated with RCM results.

RESULTS

Seventy-two patients were included. Mean age was 66.8 years (standard deviation, 11.1; range, 38-89); 69.4% were men. Seventy of 72 lesions (97.2%) were located on the head and neck with mean largest clinical diameter of 1.3 cm (range, 0.3-5). Diagnostic accuracy for detection of residual melanoma in the tumor debulk (after biopsy) had a sensitivity of 96.7% and a specificity of 66.7% when compared with histopathology. RCM margin assessment revealed an overall agreement with final histopathology of 85.9% (κ = 0.71; P < .001).

LIMITATIONS

No RCM imaging beyond initial planned margins was performed.

CONCLUSION

RCM showed moderate to excellent overall agreement between RCM imaging of LM/LMM and histopathology of staged excision margins.

Comparing the efficacy of different methods of faecal microbiota transplantation via oral capsule, oesophagogastroduodenoscopy, colonoscopy, or gastric tube

BACKGROUND

The increasing prevalence of multidrug-resistant organism (MDRO) carriage poses major challenges to medicine as healthcare costs increase. Recently, faecal microbiota transplantation (FMT) has been discussed as a novel and effective method for decolonizing MDRO.

AIM

To compare the efficacy of different FMT methods to optimize the success rate of decolonization in patients with MDRO carriage.

METHODS

This prospective cohort study enrolled patients with MDRO carriages from 2018 to 2021. Patients underwent FMT via one of the following methods: oral capsule, oesophagogastroduodenoscopy (EGD), colonoscopy, or gastric tube.

FINDINGS

A total of 57 patients underwent FMT for MDRO decolonization. The colonoscopy group required the shortest time for decolonization, whereas the EGD group required the longest (24.9 vs 190.4 days, P = 0.022). The decolonization rate in the oral capsule group was comparable to that in the EGD group (84.6% vs 85.7%, P = 0.730). An important clinical factor associated with decolonization failure was antibiotic use after FMT (odds ratio = 6.810, P = 0.008). All four groups showed reduced proportions of MDRO species in microbiome analysis after FMT.

CONCLUSION

Compared to other conventional methods, the oral capsule is an effective FMT method for patients who can tolerate an oral diet. The discontinuation of antibiotics after FMT is a key factor in the success of decolonization.

Patient Education on Scarring Following Mohs Micrographic Surgery: Patient Preference for Information Delivery

BACKGROUND

There are multiple modalities for patient education ranging from written to audiovisual formats. However, little is known regarding which modality is optimal.

OBJECTIVE

To assess patient preference for educational materials about scar care following surgery for facial skin cancer using the FACE-Q Skin Cancer patient reported outcome measure.

MATERIALS AND METHODS

On the day of Mohs surgery, patients were given a written handout or viewed a 3-minute animation video regarding best practices in scar improvement. Afterward, patients received the FACE-Q Skin Cancer-Satisfaction with Information: Appearance scale. Three months later, patients were called and given the same scale and additional questions regarding scar care.

RESULTS

A total of 75 patients were enrolled. There was no difference between the 2 groups' preoperative information scores (p = .85) and the three-month postoperative scores (p = .37). The change in preoperative and postoperative score showed no significant difference between the 2 groups (p = .21); but there was a trend of higher satisfaction in the video group on the day of Mohs surgery. After the 3-month timepoint, there was a higher satisfaction trend observed with the written handout group.

CONCLUSION

Patient preferences in information delivery and accessibility will contribute to greater information retention and satisfaction.

Sun Protection Behavior Following Skin Cancer Resection and Reconstruction

Increased exposure to ultraviolet radiation (UVR) is associated with an increased risk of nonmelanoma skin cancer. Cutaneous surgery can be negatively influenced by UVR, causing delayed wound healing, hyperpigmentation of the scar, and an increased incidence of additional skin cancers. By changing sun protection behavior, these risks can be limited. Therefore, this study evaluates changes in patients' sun protective behavior after Mohs micrographic surgery (MMS). Patients undergoing MMS between December 2017 and November 2019 were included. Patients were asked to complete the FACE-Q Skin Cancer - Sun Protection Behavior checklist before and 3 months and 1 year post-surgery. A total of 125 patients completed the pre-operative and 3-months post-operative checklists, and 89 (71.2%) completed the 1-year post-operative checklist. Reported sun protective behaviors increased post-surgery at all time points (p < 0.001). Patients with a prior history of facial skin cancer demonstrated a larger increase in sun protection behaviors after surgery than patients without a history of facial skin cancer (p = 0.04). Patients with defects located on the ear or scalp demonstrated a lesser increase in sun protection behaviors than patients with defects located in more conspicuous areas as the face (p = 0.02). Our study demonstrates a change in sun protection behavior, with an increase in sun protection behavior over time in patients after MMS. However, more improvement is possible. Targeted counseling can increase sun protection behavior in patients without a history of facial skin cancer and patients with skin cancer located on the ears or scalp.

Development of a Core Outcome Set for Basal Cell Carcinoma (BCC), Including Low-Risk and Advanced Tumors

BACKGROUND

There is variation in the outcomes reported in clinical studies of basal cell carcinoma (BCC). This can prevent effective meta-analyses to answer important clinical questions.

OBJECTIVE

To identify a recommended minimum set of core outcomes for BCC clinical trials.

METHODS

Patient and professional Delphi process to cull a long-list, culminating in a consensus meeting. To be provisionally accepted, outcomes needed to be deemed 'important' (score: 7-9, of maximum of 9) by 70% of each stakeholder group.

RESULTS

235 candidate outcomes identified via a systematic literature review and survey of key stakeholders were reduced to 74 that were rated by 100 health care professionals and patients in two Delphi rounds. 27 outcomes were provisionally accepted. The final core set of 5 agreed-upon outcomes after the consensus meeting was: complete response; persistent or serious adverse events; recurrence-free survival; quality of life; and patient satisfaction, including with cosmetic outcome.

LIMITATIONS

English-speaking patients and professionals rated outcomes extracted from English-language studies.

CONCLUSIONS

A core outcome set (COS) for basal cell carcinoma has been developed. Use of relevant measures may improve the utility of clinical research and the quality of therapeutic guidance available to clinicians.

Nasal skin reconstruction: Time to rethink the reconstructive ladder?

BACKGROUND

Nasal scarring can compromise aesthetics and function given its complex three-dimensional structure and central location. This study aimed to measure patients' satisfaction after reconstruction for nasal defects following Mohs micrographic surgery.

METHODS

Patients presenting with nasal nonmelanoma skin cancer at Memorial Sloan Kettering Cancer Center New York, USA and Catharina Hospital Eindhoven, Netherlands from April 2017 to November 2019 were asked to participate. Reconstruction type, complications, and patients satisfaction were assessed. Patients completed the FACE-Q Skin Cancer - Satisfaction with Facial Appearance scale (preoperative and 1-year postoperative) and the Appraisal of Scars scale (1-year postoperative).

RESULTS

A total of 128 patients completed the preand postoperative scales. There were 35 (27%) surgical defects repaired with primary closures, 71 (55.5%) with flaps, and 22 (17.2%) with full-thickness skin grafts (FTSG). Patients that underwent a flap or FTSG reconstruction had higher scar satisfaction scores than primary closures (p = 0.03). A trend was seen with patients following flap reconstructions scoring 7.8 points higher than primary closures and patients with upper nose defects scoring 6.4 points higher than lower nose defects. Males were significantly more satisfied than females. No significant difference was observed in the preoperative and postoperative facial appearance scores between the three groups (p = 0.39).

CONCLUSION

Patients are more satisfied in the long term with their scars after flap reconstructions compared to primary closures. Therefore, nasal skin reconstruction may not follow the traditional reconstructive ladder and more complex approaches may lead to higher long-term scar satisfaction.

A Systematic Review and Overview of Flap Reconstructive Techniques for Nasal Skin Defects

Background: Reconstruction of nasal skin defects can be challenging due to limited skin laxity and underlying cartilage and, therefore, often require a complex repair. The aim of this review is to systematically analyze the literature on nasal skin reconstructions with specific detail to flap reconstructions. Methods: A systematic literature review of nasal skin reconstruction was performed and focused on flap reconstructions. Flap reconstructions were stratified based on defect size, nasal subunit, and reconstruction type. Complication rates (CRs) and patient outcomes were also assessed. Results: A total of 176 articles (11,370 patients) met the inclusion criteria. Of these, 59 articles showed various flap techniques. For defects ≤1.5 cm, every subunit had four to six options except the alar rim, which showed one option. Rotation-advancement flaps were mostly used for the nasal tip and sidewall, whereas bilobed flaps were used more for the ala and dorsum. Defects >1.5 cm were most commonly reconstructed with the forehead flap. The mean CR of flap reconstructions was 13.8%. Only 8 of the 176 articles (4.5%) reported patient satisfaction using a standardized questionnaire. Conclusion: This review shows various flap reconstruction options with their corresponding CR that will help guide the surgeon in choosing reconstructive options for different nasal skin defects.

1363 Oesophago-Pleural Fistula After Pneumonectomy; A Systematic Review

Introduction

Oesophago-pleural fistula (OPF) is an infrequent but highly complex complication of pneumonectomy with a mortality of up to 63%. There is a paucity of data on the optimal treatment strategy.

Method

Systematic review was conducted in line with PRISMA guidance concerning OPF following pneumonectomy. Demographic, operative and management data were analysed.

Results

30 full manuscripts of the 76 abstracts were included in the analysis. Data was limited to case reports or small series. In total, information for 58 patients was included. Median age was 59 years, with a median follow up time was 18 months. Most authors adopted sepsis control with chest drainage and pleural lavage and the mean number of interventions was 1.6. Overall mortality was 31% (18/58). There was no significant difference between the time to presentation following left (29.2+/-39.28 months) and right pneumonectomy (66.24+/-110.62) (p = 0.2271) nor any significant difference between successful outcomes following intervention for OPF after left (11/14) compared to right pneumonectomy (31/41) (p = 0.8219) or 90-day mortality (p = 0.4571). However, 26% of patients had synchronous broncho-pleural fistula and 90-day mortality was significantly higher in these patients (6/15 vs 6/43. p = 0.0395). 25 patients who underwent additional pericardial, oesophageal or a nodal resection or intervention at the time of pneumonectomy had a significantly reduced mean time to presentation with OPF (21.49+/-60.15 vs. 84.99+/-114.31. p = 0.0148) and a higher 90-day mortality (8/25 vs 3/32. P = 0.0414).

Conclusions

Major heterogeneity of management hinders the introduction of standardised guidance of post-pnuemonectomy OPF. An MDT approach involving Oesophago-gastric and Cardio-Thoracic Surgery is vital.

Cancer worry after facial nonmelanoma skin cancer resection and reconstruction: A 1-year prospective study

OBJECTIVE

Nonmelanoma skin cancer (NMSC) is one of the most diagnosed cancers in the world, with the number of new occurrences rising every year. Most patients with facial skin cancer experience cancer-related worry. Yet, little is known about their worry during the period after cancer treatment. This study aimed to assess the long-term change of cancer worry after surgical treatment in patients with NMSC.

METHODS

Patients undergoing surgery for facial NMSC between December 2017 and March 2020 were asked to complete the FACE-Q Skin Cancer-Cancer Worry scale before (baseline), 3-month, and 1-year post-surgery.

RESULTS

A total of 151 patients completed the baseline and 3-month, and 99 (65.6%) the 1-year post-operative survey. A significant decrease in cancer worry score was seen between baseline and 3-month post-surgery (p < 0.001). No difference was found between the 3-month and 1-year post-surgery scores (p = 0.78). Less improvement in cancer worry was seen for patients who had one facial skin cancer in their medical history (p = 0.001) and patients who had a history of facial surgery (p < 0.001).

CONCLUSION

Post-surgery patients still experience cancer worry. Therefore, targeted counseling might be of value when coping with cancer-related concerns. Patients with a history of facial NMSC and patients with a history of facial surgery might benefit from additional counseling.

Treatment of Extramammary Paget Disease and the Role of Reflectance Confocal Microscopy: A Prospective Study

BACKGROUND

Extramammary Paget disease (EMPD) poses treatment challenges. Invasive and noninvasive treatment modalities exist with variable success reported. Reflectance confocal microscopy (RCM) is emerging as an adjuvant diagnostic tool.

OBJECTIVE

To evaluate the treatment of EMPD patients and the role of RCM.

METHODS

Prospective study. Demographic and tumor characteristics were recorded. Handheld-RCM was performed and correlated with histology. Treatment, clearance, pathology, and follow-up were all recorded.

RESULTS

Thirty-six EMPD lesions in 33 patients were included. Mean age was 71.7 years, and 23 were men. Mean number of surgical stages needed to clear margins was 1.9 (SD, 0.9; 1.0-3.0 stages), and mean margin needed to clear was 1.8 cm. Reflectance confocal microscopy correlated well with scouting punch biopsies (kappa, 0.93; p < .001). Disruption of the dermoepidermal junction was associated with invasive EMPD versus in situ (83.3% vs 25.9%) on histology (p = .01).

LIMITATIONS

Relatively small sample size.

CONCLUSION

Extramammary Paget disease is challenging, and lesion demarcation is of the utmost importance. Using a staged surgical excision approach, the mean margins needed were 1.8 cm, less than previously reported. Nonsurgical modalities, including radiation therapy, imiquimod, or photodynamic therapy can be considered if surgery is not pursued. Reflectance confocal microscopy is a valuable noninvasive imaging modality for the management of EMPD.

Evaluating a Modular Approach to Therapy for Children With Anxiety, Depression, Trauma, or Conduct Problems (MATCH) in School-Based Mental Health Care: Study Protocol for a Randomized Controlled Trial

Introduction: Schools have become a primary setting for providing mental health care to youths in the U.S. School-based interventions have proliferated, but their effects on mental health and academic outcomes remain understudied. In this study we will implement and evaluate the effects of a flexible multidiagnostic treatment called Modular Approach to Therapy for Children with Anxiety, Depression, Trauma, or Conduct Problems (MATCH) on students' mental health and academic outcomes.

Methods and Analysis: This is an assessor-blind randomized controlled effectiveness trial conducted across five school districts. School clinicians are randomized to either MATCH or usual care (UC) treatment conditions. The target sample includes 168 youths (ages 7–14) referred for mental health services and presenting with elevated symptoms of anxiety, depression, trauma, and/or conduct problems. Clinicians randomly assigned to MATCH or UC treat the youths who are assigned to them through normal school referral procedures. The project will evaluate the effectiveness of MATCH compared to UC on youths' mental health and school related outcomes and assess whether changes in school outcomes are mediated by changes in youth mental health.

Ethics and Dissemination: This study was approved by the Harvard University Institutional Review Board (IRB14-3365). We plan to publish the findings in peer-reviewed journals and present them at academic conferences.

Clinical Trial Registration:ClinicalTrials.gov ID: NCT02877875. Registered on August 24, 2016.

To see or not to see: Impact of viewing facial skin cancer defects prior to reconstruction

Patient expectations of the scar after Mohs micrographic surgery (MMS) are often not realistic, leading to subsequent psychosocial sequelae such as anxiety, depression, and avoidance of social situations. When patient expectations are not met, this may also contribute to a decrease in patient satisfaction after surgery. Therefore, altering expectation levels may change patient satisfaction and psychosocial distress levels after surgery. To assess whether patient satisfaction improves in patients after MMS when patients view the surgical defect prior to reconstruction. Patients undergoing facial MMS between December 2017 and September 2019 were included. Patients received or did not receive a mirror after MMS to view the surgical defect before closing the defect. Patients were asked to complete the Dutch FACE-Q Skin Cancer before, one-week, three-months, and one-year after MMS. A total of 113 patients where included. One-hundred-eight (95.6%), 113 (100%), and 93 (82.3%) questionnaires were completed, one-week, three-months, and one-year follow-up, respectively. Satisfaction with facial appearance and appraisal of scars significantly improved over time for all patients, no such improvement was seen for appearance-related distress. Female patients who looked in the mirror had higher satisfaction with facial appearance than female patients who did not look in the mirror. Also, lower appearance-related distress scores were seen in patients who looked in the mirror prior to a flap reconstruction. Showing the defect in the mirror prior to the reconstruction may result in higher patient satisfaction in female patients and patients before undergoing a flap reconstruction.

Development of a core outcome set for cutaneous squamous cell carcinoma trials: identification of core domains and outcomes

BACKGROUND

The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials.

OBJECTIVES

To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC.

METHODS

One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders. After consolidation of this long list, 55 candidate outcomes were rated by 19 physician and 10 patient stakeholders, in two rounds of Delphi exercises. Outcomes scored 'critically important' (score of 7, 8 or 9) by ≥ 70% of patients and ≥ 70% of physicians were provisionally included. At the consensus meeting, after discussion and voting of 44 international experts and patients, the provisional list was reduced to a final core set, for which consensus was achieved among all meeting participants.

RESULTS

A core set of seven outcomes was finalized at the consensus meeting: (i) serious or persistent adverse events, (ii) patient-reported quality of life, (iii) complete response, (iv) partial response, (v) recurrence-free survival, (vi) progression-free survival and (vii) disease-specific survival.

CONCLUSIONS

In order to increase the comparability of results across trials and to reduce selective reporting bias, cSCC researchers should consider reporting these core outcomes. Further work needs to be performed to identify the measures that should be reported for each of these outcomes.

Core Outcome Set for Actinic Keratosis Clinical Trials

Importance

Although various treatments have been found in clinical trials to be effective in treating actinic keratosis (AK), researchers often report different outcomes. Heterogeneous outcome reporting precludes the comparison of results across studies and impedes the synthesis of treatment effectiveness in systematic reviews.

Objective

To establish an international core outcome set for all clinical studies on AK treatment using systematic literature review and a Delphi consensus process.

Evidence Review

Survey study with a formal consensus process. The keywords actinic keratosis and treatment were searched in PubMed, Embase, CINAHL, and the Cochrane Library to identify English-language studies investigating AK treatments published between January 1, 1980, and July 13, 2015. Physician and patient stakeholders were nominated to participate in Delphi surveys by the Measurement of Priority Outcome Variables in Dermatologic Surgery Steering Committee members. All participants from the first round were invited to participate in the second round. Outcomes reported in randomized controlled clinical trials on AK treatment were rated via web-based e-Delphi consensus surveys. Stakeholders were asked to assess the relative importance of each outcome in 2 Delphi survey rounds. Outcomes were provisionally included, pending the final consensus conference, if at least 70% of patient or physician stakeholders rated the outcome as critically important in 1 or both Delphi rounds and the outcome received a mean score of 7.5 from either stakeholder group. Data analysis was performed from November 5, 2018, to February 27, 2019.

Findings

A total of 516 outcomes were identified by reviewing the literature and surveying key stakeholder groups. After deduplication and combination of similar outcomes, 137 of the 516 outcomes were included in the Delphi surveys. Twenty-one physicians and 12 patients participated in round 1 of the eDelphi survey, with 17 physicians (81%) retained and 12 patients (100%) retained in round 2. Of the 137 candidate outcomes, 9 met a priori Delphi consensus criteria, and 6 were included in the final outcomes set after a consensus meeting: complete clearance of AKs, percentage of AKs cleared, severity of adverse events, patient perspective on effectiveness, patient-reported future treatment preference, and recurrence rate. It was recommended that treatment response be assessed at 2 to 4 months and recurrence at 6 to 12 months, with the AK rate of progression to cutaneous squamous cell carcinoma reported whenever long-term follow-up was possible.

Conclusions and Relevance

Consensus was reached regarding a core outcome set for AK trials. Further research may help determine the specific outcome measures used to assess each of these outcomes.

Incompletely excised lentigo maligna melanoma is associated with unpredictable residual disease: clinical features and the emerging role of reflectance confocal microscopy

BACKGROUND

Lentigo maligna/lentigo maligna melanoma (LM/LMM) poses a treatment and surgical challenge given unpredictable subclinical extension resulting in incomplete excision.

OBJECTIVES

To describe the demographic, clinical and pathologic characteristics of incompletely excised LM/LMM. To evaluate the potential role of reflectance confocal microscopy (RCM).

PATIENTS AND METHODS

A retrospective review of a melanoma database at a tertiary cancer centre for patients referred with 'incompletely excised LM/LMM' or 'incompletely excised melanoma' between October 2006 and July 2017. We recorded clinical and pathological data and surgical margins needed to clear the residual LM/LMM. The second part consisted of a prospective cohort of patients in which RCM was performed when presenting with incompletely excised LM/LMM.

RESULTS

We included a total of 67 patients (retrospective + prospective cohort); mean age was 64.9 (standard deviation: 11.3) years and 52.2% were males. For the retrospective cohort (n = 53), the mean scar size was 3.4 cm. The average initial margins excised prior to presentation were 4.8 mm (range 3-7 mm). The average additional margin needed to clear the residual, incompletely excised LM/LMM was 7.8 mm. For the prospective cohort (n = 14), there were no differences in age, gender or size when compared to the retrospective cohort. RCM had a diagnostic accuracy of 78.6%, a sensitivity of 90.9%, a specificity of 33.3% and a positive predictive value of 83.3% for the detection of incompletely excised LM/LMM.

CONCLUSIONS

Incompletely excised LM/LMM is a poorly characterized clinical-pathological scenario that may require considerable extra margins for microscopic clearance. RCM may emerge as a valuable tool for the evaluation of patients with incompletely excised LM/LMM.

Deep Learning for Pediatric Posterior Fossa Tumor Detection and Classification: A Multi-Institutional Study

BACKGROUND AND PURPOSE

Posterior fossa tumors are the most common pediatric brain tumors. MR imaging is key to tumor detection, diagnosis, and therapy guidance. We sought to develop an MR imaging-based deep learning model for posterior fossa tumor detection and tumor pathology classification.

MATERIALS AND METHODS

The study cohort comprised 617 children (median age, 92 months; 56% males) from 5 pediatric institutions with posterior fossa tumors: diffuse midline glioma of the pons (n = 122), medulloblastoma (n = 272), pilocytic astrocytoma (n = 135), and ependymoma (n = 88). There were 199 controls. Tumor histology served as ground truth except for diffuse midline glioma of the pons, which was primarily diagnosed by MR imaging. A modified ResNeXt-50-32x4d architecture served as the backbone for a multitask classifier model, using T2-weighted MRIs as input to detect the presence of tumor and predict tumor class. Deep learning model performance was compared against that of 4 radiologists.

RESULTS

Model tumor detection accuracy exceeded an AUROC of 0.99 and was similar to that of 4 radiologists. Model tumor classification accuracy was 92% with an F₁ score of 0.80. The model was most accurate at predicting diffuse midline glioma of the pons, followed by pilocytic astrocytoma and medulloblastoma. Ependymoma prediction was the least accurate. Tumor type classification accuracy and F₁ score were higher than those of 2 of the 4 radiologists.

CONCLUSIONS

We present a multi-institutional deep learning model for pediatric posterior fossa tumor detection and classification with the potential to augment and improve the accuracy of radiologic diagnosis.

Variable Refocusing Flip Angle Single-Shot Imaging for Sedation-Free Fast Brain MRI

BACKGROUND AND PURPOSE

Conventional single-shot FSE commonly used for fast MRI may be suboptimal for brain evaluation due to poor image contrast, SNR, or image blurring. We investigated the clinical performance of variable refocusing flip angle single-shot FSE, a variation of single-shot FSE with lower radiofrequency energy deposition and potentially faster acquisition time, as an alternative approach to fast brain MR imaging.

MATERIALS AND METHODS

We retrospectively compared half-Fourier single-shot FSE with half- and full-Fourier variable refocusing flip angle single-shot FSE in 30 children. Three readers reviewed images for motion artifacts, image sharpness at the brain-fluid interface, and image sharpness/tissue contrast at gray-white differentiation on a modified 5-point Likert scale. Two readers also evaluated full-Fourier variable refocusing flip angle single-shot FSE against T2-FSE for brain lesion detectability in 38 children.

RESULTS

Variable refocusing flip angle single-shot FSE sequences showed more motion artifacts (P < .001). Variable refocusing flip angle single-shot FSE sequences scored higher regarding image sharpness at brain-fluid interfaces (P < .001) and gray-white differentiation (P < .001). Acquisition times for half- and full-Fourier variable refocusing flip angle single-shot FSE were faster than for single-shot FSE (P < .001) with a 53% and 47% reduction, respectively. Intermodality agreement between full-Fourier variable refocusing flip angle single-shot FSE and T2-FSE findings was near-perfect (κ = 0.90, κ = 0.95), with an 8% discordance rate for ground truth lesion detection.

CONCLUSIONS

Variable refocusing flip angle single-shot FSE achieved 2× faster scan times than single-shot FSE with improved image sharpness at brain-fluid interfaces and gray-white differentiation. Such improvements are likely attributed to a combination of improved contrast, spatial resolution, SNR, and reduced T2-decay associated with blurring. While variable refocusing flip angle single-shot FSE may be a useful alternative to single-shot FSE and, potentially, T2-FSE when faster scan times are desired, motion artifacts were more common in variable refocusing flip angle single-shot FSE, and, thus, they remain an important consideration before clinical implementation.

Functional status and survival in patients ≥85 years of age who have keratinocyte carcinoma: A retrospective cohort study

BACKGROUND

Functional status assessment may help estimate which patients ≥85 years of age will benefit from surgical treatment for keratinocyte carcinoma (KC), but predictive value for short-term survival in this population has not been determined.

OBJECTIVE

We sought to assess the predictive value of functional status for short-term survival in patients ≥85 years of age who have KC.

METHODS

This was a retrospective cohort review of 238 patients ≥85 years of age who presented for the management of KC between 2010 and 2015. Functional status was assessed with the Karnofsky Performance Scale (KPS) and Katz Activities of Daily Living (ADL) index. Overall survival was determined.

RESULTS

Lower functional status scores of KPS ≤40 and Katz ADL ≤4 were associated with 37% and 53% survival at 2 years, respectively.

LIMITATIONS

Retrospective design and single-center study.

CONCLUSION

In this study, KPS and Katz ADL predicted short-term survival. Patients with low functional status scores had significantly decreased survival at 2 years, with double the death rate of patients with high functional status. Functional status should be considered during shared decision-making for elderly individuals who are seeking treatment for KC.

Utilization of Facebook for support and education by patients with skin cancer

The expanding role of social media in medical care has resulted in dermatology patients seeking support online regarding personal experience with diagnosis and treatment of skin cancer. Owing to increased privacy settings in closed Facebook groups, the current study analyzed themes of keratinocyte carcinoma patients' posts within a relatively private social media network. Although the majority of messages included sharing personal experience and provided psychosocial support (50%), there were a significant number of posts offering medical advice (35%), with the majority of such replies being unsupported by evidence-based medicine (87%). The level of medical misinformation and potential harm to patients seeking advice online is important for medical practitioners treating skin cancer and provides impetus for possible further research into online support and education groups that are moderated for misinformation.

Outpatient dermatology consultations for oncology patients with acute dermatologic adverse events impact anticancer therapy interruption: a retrospective study

BACKGROUND

Dermatologic adverse events (dAEs) of anticancer therapies may negatively impact dosing and quality of life. While therapy interruption patterns due to dAEs have been studied in hospitalized cancer patients, similar outcomes in outpatient oncodermatology are lacking.

OBJECTIVES

To analyse the therapy interruption patterns, clinico-histopathologic characteristics and management outcomes of outpatient dermatology consultations for acute dAEs attributed to the most frequently interrupted class of oncologic agents.

METHODS

We performed a retrospective cohort study of all cancer patients who received a same-day outpatient dermatology consultation for acute dAEs at our institution from 1 January to 30 June 2015. Relevant data were abstracted from electronic medical records, including demographics, oncologic history and explicit recommendations by both the referring clinician and consulting dermatologist on anticancer therapy interruption. Consultations with the most frequently interrupted class of oncologic treatment were characterized according to clinico-histopathologic features, dermatologic management and clinical outcomes.

RESULTS

There were 426 same-day outpatient dermatology consultations (median age 59, 60% female, 30% breast cancer), of which 295 (69%) had systemic anticancer therapy administered within 30 days prior. There was weak inter-rater agreement between referring clinicians and consulting dermatologists on interruption of anticancer treatment (n = 150, κ = 0.096; 95% CI -0.02 to 0.21). Seventy-three (25%) consultations involved interruption by the referring clinician, most commonly targeted therapy (24, 33%). Maculopapular rash was commonly observed in 23 consultations with 25 dAEs attributed to targeted agents (48%), and topical corticosteroids were most frequently utilized for management (22, 38%). The majority (83%) of consultations with targeted therapy-induced dAEs responded to dermatologic treatment and 84% resumed oncologic therapy, although three (19%) at a reduced dose. Rash recurred only in two instances (13%).

CONCLUSIONS

A high frequency of positive outcomes in the management of targeted therapy-induced dAEs by outpatient consulting dermatologists and low recurrence of skin toxicity suggests impactful reductions in interruption of anticancer therapy.

Management of complex head-and-neck basal cell carcinomas using a combined reflectance confocal microscopy/optical coherence tomography: a descriptive study

INTRODUCTION

Recently, a combined reflectance confocal microscopy (RCM)-optical coherence tomography (OCT) has been tested for the diagnosis of basal cell carcinoma (BCC). Evaluating the role of RCM-OCT in management of complex BCCs has not been studied. The objective of the study was to investigate the utility of a new combined RCM-OCT device in the evaluation and management of complex BCCs in a descriptive study.

METHODS

Prospective study of consecutive cases (July 2018-June 2019) of biopsy-proven 'complex' BCC defined as BCC in the head-and-neck area with multiple high-risk criteria such as large size in the mask area, multiple recurrences, and high-risk subtype. All cases were evaluated with a combined RCM-OCT device that provided simultaneous image viewing on a screen. Lesions were evaluated bedside with RCM-OCT according to previously described criteria.

RESULTS

Ten patients with complex head-and-neck BCCs had mean age of 73.1 ± 13.0 years. Six (60%) patients were males. Mean BCC clinical size was 1.9 ± 1.2 cm (range 0.6-4.0 cm). RCM detected residual BCC in 8 out of 10 cases (80%) and OCT detected residual BCC in all 10 cases (100%). Six BCCs (60%) had a depth estimate of > 1000 µm under OCT. In five cases, (50%) RCM-OCT imaging results led to a change/modification in BCC management.

CONCLUSION

The use of a combined RCM-OCT device may help in the evaluation of complex head-and-neck BCCs by guiding treatment selection and defining the extent of surgery.
