PURPOSE/OBJECTIVE:Acute radiation dermatitis (ARD) is common after radiation therapy for breast cancer, with data indicating that ARD may disproportionately affect Black or African American (AA) patients. We evaluated the effect of skin of color (SOC) on physician-reported ARD in patients treated with radiation therapy. METHODS AND MATERIALS/METHODS:We identified patients treated with whole breast or chest wall ± regional nodal irradiation or high tangents using 50 Gy in 25 fractions from 2015 to 2018. Baseline skin pigmentation was assessed using the Fitzpatrick scale (I = light/pale white to VI = black/very dark brown) with SOC defined as Fitzpatrick scale IV to VI. We evaluated associations among SOC, physician-reported ARD, late hyperpigmentation, and use of oral and topical treatments for RD using multivariable models. RESULTS:A total of 325 patients met eligibility, of which 40% had SOC (n = 129). On multivariable analysis, Black/AA race and chest wall irradiation had a lower odds of physician-reported grade 2 or 3 ARD (odds ratio [OR], 0.110; 95% confidence interval [CI], 0.030-0.397; P = .001; OR, 0.377; 95% CI, 0.161-0.883; P = .025), whereas skin bolus (OR, 8.029; 95% CI, 3.655-17.635; P = 0) and planning target volume D0.03cc (OR, 1.001; 95% CI, 1.000-1.001; P = .028) were associated with increased odds. On multivariable analysis, SOC (OR, 3.658; 95% CI, 1.236-10.830; P = .019) and skin bolus (OR, 26.786; 95% CI, 4.235-169.432; P = 0) were associated with increased odds of physician-reported late grade 2 or 3 hyperpigmentation. There was less frequent use of topical steroids to treat ARD and more frequent use of oral analgesics in SOC versus non-SOC patients (43% vs 63%, P < .001; 50% vs 38%, P = .05, respectively). CONCLUSIONS:Black/AA patients exhibited lower odds of physician-reported ARD. However, we found higher odds of late hyperpigmentation in SOC patients, independent of self-reported race. These findings suggest that ARD may be underdiagnosed in SOC when using the physician-rated scale despite this late evidence of radiation-induced skin toxicity.

Radiation-induced skin changes after breast or chest wall irradiation in patients with breast cancer and skin of color: a systematic review

Purswani, Juhi M; Nwankwo, Christy; Adotama, Prince; Gutierrez, Daniel; Perez, Carmen A; Tattersall, Ian W; Gerber, Naamit K
INTRODUCTION/BACKGROUND:The purpose of this study is to systematically review data pertaining to breast cancer and radiation-induced skin reactions in patients with skin of color (SOC), as well as data pertaining to objective measurements of skin pigmentation in the assessment of radiation dermatitis (RD). METHODS AND MATERIALS/METHODS:We conducted a systematic review utilizing MEDLINE electronic databases to identify published studies until August 2022. Key inclusion criteria included studies that described RD in breast cancer with data pertaining to skin of color and/or characterization of pigmentation changes after radiation. RESULTS:We identified 17 prospective cohort studies, 7 cross-sectional studies, 5 retrospective studies and 4 randomized controlled trials. Prospective cohort and retrospective series demonstrate worse RD in African American (AA) patients using subjective physician-graded scales. There is more limited data in patients representing other non-White racial subgroups with SOC. 2 studies utilize patient reported outcomes and 15 studies utilize objective methods to characterize pigmentation change after radiation. There are no prospective and randomized studies that objectively describe pigmentation changes with radiotherapy in SOC. CONCLUSIONS:AA patients appear to have worse RD outcomes, though this is not uniformly observed across all studies. There are no studies that describe objective measures of RD and include baseline skin pigmentation as a variable, limiting the ability to draw uniform conclusions on the rate and impact of RD in SOC. We highlight the importance of objectively characterizing SOC and pigmentation changes before, during and after radiotherapy to understand the incidence and severity of RD in SOC.

Risk of Radiation Dermatitis in Patients with Skin of Color Who Undergo Radiation to the Breast or Chest Wall Irradiation and Regional Nodes [Meeting Abstract]

Purswani, J; Oh, C; Xiao, J; Teruel, J R; Perez, C A; Gutierrez, D; Adotama, P; Tattersall, I; Gerber, N K
Purpose/Objective(s): Radiation dermatitis (RD) is common after RT for breast cancer with data indicating potentially worse RD in African American (AA) patients (pts). Current measures of RD, such as the CTCAE, do not include hyperpigmentation, which may disproportionately affect how RD is classified and treated in pts with skin of color (SOC). We aim to characterize RD in SOC and identify factors, including baseline skin pigmentation (BSP) that predict RD. Materials/Methods: Pts treated with whole breast (WB) or chest wall (CW) with regional nodal RT or high tangents with 50 Gy in 25 fractions from 2015-2018 were identified. Three dermatologists independently classified BSP using photographs from CT simulation based on the Fitzpatrick scale ([FS], range=I-VI; I=light/pale white to VI=black/ very dark brown). SOC was defined as FS IV-VI. Pt characteristics were investigated for association with interventions to treat RD, clinician-graded acute RD, and late skin toxicity (NCI CTCAE scale) with Chi-squared and logistic regression analyses.
Result(s): 325 pts met eligibility criteria (58 African American [AA], 42 Asian, 151 Caucasian, 77 other). 40% (n=129) had SOC, 60% underwent CW RT, 40% WB RT and 82% had systemic therapy. Pts with SOC were more likely to be Hispanic (14% vs 8% p=0.007), AA (43% vs 1%, p<0.001) and have greater mean BMI (28.0 vs 26.5, p=0.02). Acute grade 2/3 RD was lower in SOC (FS I 60%, FS II 63%, FS III 52%, FS IV 64%, FS V 40%, FS VI 41%; p=0.049). Increased BSP (OR 0.83; p=0.01) and AA pts (OR: 0.22; p<0.001) had lower odds of acute grade 2/3 RD, whereas bolus and dosimetric parameters such as increased PTV volume had increased odds. On multivariable analysis (MVA), AA pts and bolus remained significant (OR: 0.14, p=0.01; OR: 6.63 p<0.001, respectively). Topical steroid use to treat RD was less frequent and oral analgesic use was more frequent in SOC (43% vs 63%, p<0.001; 50% vs 38%, p=0.05, respectively). Pts with increased BSP (OR 0.73, p<0.001), AA race (OR 0.19, p<0.001) and greater BMI had lower use of topical interventions whereas any boost phase, bolus, IMN RT and increased PTV volume had greater use. On MVA, AA pts (OR 0.27, p=0.04), boost (OR 2.04, p=0.033), IMN RT (OR 2.73, p=0.003) and PTV V105% (OR=1.002, p=0.03) retained significance. Late grade 2/3 hyperpigmentation was greater in SOC (16% vs 3%, p=0.01). Increased BSP (OR 2.14, p=0.001), AA pts (OR 8.18, p=0.02), bolus and CW boost had greater odds of grade 2/3 hyperpigmentation. On MVA, increased BSP (OR: 3.76, p=0.03) and bolus (OR: 14.1, p=0.01) retained significance.
Conclusion(s): We found less clinician-graded acute RD in SOC and AA pts, less frequent use of topical interventions but more oral analgesic use. We also found higher rates of late pigmentation change with increased BSP independent of race. These findings suggest that RD may be under-diagnosed in SOC. This study confirms the necessity for objective measures of RD that account for variability in BSP to accurately classify the severity of radiation skin toxicity in SOC and treat accordingly.

Cutaneous immune-related adverse events to checkpoint inhibitors

Malviya, Neeta; Tattersall, Ian W; Leventhal, Jonathan; Alloo, Allireza
The development of immunotherapy has led to a paradigm shift in the treatment of both solid and hematologic malignancies. As immunomodulatory therapies are employed with increasing frequency, a greater number of immune-related adverse reactions are being reported, and the majority of these involve the skin. As a result, dermatologists are increasingly becoming involved in the management of these cutaneous adverse reactions-often providing critical recommendations regarding ongoing cancer treatment. Cutaneous immune-related adverse reactions can vary significantly from patient to patient, making early recognition and timely intervention imperative to mitigate associated morbidity and potential treatment interruption. Although there is considerable overlap in the cutaneous adverse events caused by these immune checkpoint inhibitors, specific eruptions are characteristically associated with particular checkpoint inhibitors. In addition, a patient's comorbidities or immune status can play a significant role in the presentation and management of such adverse reactions. This review characterizes and provides management guidelines for the various cutaneous toxicities associated with checkpoint inhibitor therapy, including CTLA-4 inhibitors, PD-1 inhibitors, and PD-L1 inhibitors. © 2020 Elsevier Inc.

Cutaneous Toxicities of Immune Checkpoint Inhibitors: The Role of the Dermatologist

Tattersall, Ian William; Leventhal, Jonathan Scott
The advent of immune checkpoint inhibition represents a paradigm shift in the treatment of an increasing number of cancers. However, the incredible therapeutic promise of immunotherapy brings with it the need to understand and manage its diverse array of potential adverse events. The skin is the most common site of immune-related adverse vents (irAEs), which can present with a wide variety of disparate morphologies and severities. These toxicities can endanger patient health and the ability to continue on therapy. This review summarizes our current understanding of the presentation and management of the most common and clinically significant cutaneous irAEs associated with immune checkpoint inhibitor (ICI) therapy. Effective management of these cutaneous irAEs requires an understanding of their morphology, their appropriate clinical characterization, and their potential prognostic significance. Their treatment is additionally complicated by the desire to minimize compromise of the patient's anti-neoplastic regimen and emphasizes the use of non-immunosuppressive interventions whenever possible. However, though cutaneous irAEs represent a challenge to both oncologist and dermatologist alike, they offer a unique glimpse into the mechanisms that underlie not only carcinogenesis, but many primary dermatoses, and may provide clues to the treatment of disease even beyond cancer.

Melanoma and melanoma in-situ diagnosis after excision of atypical intraepidermal melanocytic proliferation: A retrospective cross-sectional analysis

Blank, Nina R; Hibler, Brian P; Tattersall, Ian W; Ensslin, Courtney J; Lee, Erica H; Dusza, Stephen W; Nehal, Kishwer S; Busam, Klaus J; Rossi, Anthony M
BACKGROUND:There is little evidence to guide surgical management of biopsies yielding the histologic descriptor atypical intraepidermal melanocytic proliferation (AIMP). OBJECTIVE:Determine frequency of and factors associated with melanoma and melanoma in-situ (MIS) diagnoses after excision of AIMP and evaluate margins used to completely excise AIMP. METHODS:Retrospective, cross-sectional study of 1127 biopsies reported as AIMP and subsequently excised within one academic institution. RESULTS:Melanoma (in situ, stage 1A) was diagnosed after excision in 8.2% (92/1127) of AIMP samples. Characteristics associated with melanoma/MIS diagnosis included age 60-79 years (odds ratio [OR] 8.1, 95% confidence interval [CI] 2.5-26.2), age ≥80 years (OR 7.2, 95% CI 1.7-31.5), head/neck location (OR 4.9, 95% CI 3.1-7.7), clinical lesion partially biopsied (OR 11.0, 95% CI 6.7-18.1), and lesion extending to deep biopsy margin (OR 15.1, 95% CI 1.7-136.0). Average ± standard deviation surgical margin used to excise AIMP lesions was 4.5 ± 1.8 mm. LIMITATIONS/CONCLUSIONS:Single-site, retrospective, observational study; interobserver variability across dermatopathologists. CONCLUSION/CONCLUSIONS:Dermatologists and pathologists can endeavor to avoid ambiguous melanocytic designations whenever possible through excisional biopsy technique, interdisciplinary communication, and ancillary studies. In the event of AIMP biopsy, physicians should consider the term a histologic description rather than a diagnosis, and, during surgical planning, use clinicopathologic correlation while bearing in mind factors that might predict true melanoma/MIS.
