Song C, Li JH, Luo XY, Zhou P, Yang LF, Peng JZ. The clinical effect of modified slow Mohs circular skin biopsy on penoscrotal extramammary Paget's disease. Asian J Surg 2023; 46:4261-4266. [PMID: 36737341 DOI: 10.1016/j.asjsur.2023.01.079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 01/09/2023] [Accepted: 01/17/2023] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE Determining the tumor margin is the main problem in penoscrotal extramammary Paget's disease (PEMPD) surgery. This study aimed to explore the role of modified slow Mohs circular skin biopsy in determining the tumor margin in patients with PEMPD before operation. METHODS Thirty-six PEMPD patients were divided into the control group and the observation group according to the simple randomization method. The control group, which consisted of 16 patients, underwent wide local excision, and the observation group, which consisted of 20 patients, underwent a modified slow Mohs circular skin biopsy to determine the tumor margin before surgery. The duration of surgery, number of frozen sections, satisfaction with the appearance of the skin, tumor recurrence rate, and incidence of functional sequelae were statistically analyzed. RESULTS The number of frozen sections, duration of surgery, incidence of functional sequelae, and tumor recurrence rate in the observation group were lower than in the control group. The satisfaction with the appearance of the skin was higher in the observation group than in the control group, and the difference was statistically significant (P < 0.05). CONCLUSION Modified slow Mohs circular skin biopsy can determine the tumor margin before surgery and reduce the number of frozen sections, tumor recurrence rate, and the incidence of functional sequelae. It also increases the postoperative satisfaction of patients.

Treatment outcomes of advanced/metastatic extramammary Paget's disease in Korean patients: KCSG-RC20-06. Cancer Med 2023; 12:15159-15175. [PMID: 37264748 PMCID: PMC10417073 DOI: 10.1002/cam4.6190] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Revised: 05/15/2023] [Accepted: 05/21/2023] [Indexed: 06/03/2023] Open
Abstract
BACKGROUND Extramammary Paget's disease (EMPD) is rare. There are no standard treatments due to its rarity and few clinical trials. METHODS The objective of this multicenter study was to investigate treatment outcomes of Korean patients with advanced/metastatic EMPD. Data were collected retrospectively from 14 institutions participating in Korean Cancer Study Group (KCSG) Rare Cancer Committee. RESULTS A total of 37 patients were identified. Of these 37 patients, 6 received locoregional therapy as a first-line treatment. In 31 patients who received systemic chemotherapy as a first-line treatment, platinum-based chemotherapy (n = 22) achieved an objective response rate (ORR) of 45.5% and a median progression-free survival (PFS) of 7.89 months. Taxane-based chemotherapy (n = 8) achieved an objective response rate of 62.5% and median PFS of 9.73 months. In second-line chemotherapy, platinum-based chemotherapy (n = 4) had a disease control rate (DCR) of 75.0% and median PFS of 3.45 months. Taxane-based chemotherapy (n = 8) had a DCR of 75.0% and a median PFS of 8.67 months. Six patients received anti-human epidermal growth factor receptor 2 (HER2) antibody during first- and second-line chemotherapy. Overall, systemic chemotherapy combined with anti-HER2 antibody had an ORR of 100% and a median PFS of 13.31 months. The ORR and PFS with systemic chemotherapy combined with trastuzumab was better than platinum- and taxane-based chemotherapy only. CONCLUSIONS Due to its rarity, advanced or metastatic EMPD still has no established standard treatment. Results of our study indicate that the combination of trastuzumab with taxane has longer survival than trastuzumab monotherapy or conventional platinum- or taxane-based chemotherapy.

Abstract
PURPOSE OF REVIEW Extramammary Paget's Disease (EMPD) is an uncommon intra-epithelial malignancy, affecting primarily apocrine gland-bearing skin. EMPD is often considered an orphan diagnosis given its rarity. This review provides a contemporary overview of EMPD management. RECENT FINDINGS The mainstay of EMPD treatment centers around a high index of suspicion to allow for an early and accurate diagnosis, wide local or Mohs micrographic surgical excision with care paid toward the margin status, and thoughtful consideration for lymphadenectomy in patients with clinically positive regional disease. There is currently no consensus regarding adjuvant therapies or systemic therapies although with ongoing improvements in tumor biology and genomics, including molecular pathways and alterations specific to EMPD, targeted or combinatorial therapies may be on the horizon. SUMMARY Clinicians caring for patients with EMPD should seek consultation from or if feasible, consider referral to high-volume, experienced centers with patients counseled and provided with frequent and close follow-up for disease recurrence or progression. Collaboration with groups such as the Global Society for Rare Genitourinary Tumors, and especially patient groups will be vital to designing trials and collaborative databases.

Abstract
OBJECTIVE To evaluate the value of Wood's lamp examination combined with 5-aminolevulinic acid (5-ALA) photodynamic therapy (PDT) to determine positive tumor margins in patients with extramammary Paget's disease (EMPD) before surgery. METHODS We admitted 36 patients with EMPD from January 2016 to June 2019. The experimental group was the 5-ALA-PDT group, and the control group was the wide local excision (WLE) group. In the 5-ALA-PDT group, Wood's lamp examination combined with 5-ALA-PDT was used to trace the fluorescence range, and multipoint biopsy was performed according to the pathology to determine the final excision scope. We applied the standard partial expansion excision method for the WLE group, while frozen pathology assessment was applied to confirm the excision range. We measured the overall resection area of the WLE group and 5-ALA-PDT group. We analyzed the overall duration of surgery, the number of frozen pathology sections, patient satisfaction with appearance and function, the rate of functional sequelae, and the recurrence rate for both groups. RESULTS The results suggested that the difference in final resection margin between the WLE group and the 5-ALA-PDT group was significant. The number of frozen pathology sections, overall surgery time, and recurrence rate were significantly lower in the experimental group than in the control group (p<0.05). The occurrence rate of functional sequelae in the experimental group was lower, and patient satisfaction with appearance and function was significantly higher than that of the control group (p<0.05). CONCLUSION Wood's lamp examination combined with 5-ALA-PDT may predict tumor margins in EMPD.

Abstract
Extramammary Paget's disease (EMPD) is a rare cutaneous malignancy that most commonly affects the apocrine glands of older men and women. Because it is associated with other cancers, early diagnosis and evaluation are needed. This study is to evaluate the value of reflectance confocal microscopy (RCM) in diagnosing EMPD. A total of 73 patients with clinically suspicious diagnosis of EMPD were enrolled in this study, and the RCM device imaged their lesions. Moreover, 67 patients underwent skin biopsies to confirm the diagnosis. We retrospectively analyzed the results of RCM and histological diagnosis and then evaluated the RCM value of biopsy-confirmed lesions. Based on the RCM image analysis, 54 of 73 (74.0%) patients were diagnosed with EMPD. Of all 67 biopsied lesions, 52 (77.6%) were EMPD. Then, we analyzed the RCM characteristics of 52 cases of biopsy-confirmed EMPD, compared their RCM image characteristics of three different lesions of EMPD, and further concluded the key points of EMPD under RCM microscopy based on the 52 EMPD cases. Finally, we focused on the differential diagnosis of EMPD from other skin diseases. RCM showed great diagnostic value in diagnosing EMPD.

Abstract
Extramammary Paget’s disease (EMPD) is a rare neoplasm that usually develops in apocrine gland-bearing areas, such as the vulva, scrotum, and penis. EMPD may present with a focal, multifocal, or an ectopic lesion. Clinically, EMPD lesions often exhibit infiltrative erythema, which is sometimes similar to other skin disorders such as eczema. While primary EMPD arises as intraepithelial neoplasm of the epidermis, EMPD-like lesions may occur from epidermotropic spread of malignant cells or direct extension from an underlying internal neoplasm, known as secondary EMPD. Because treatment strategies differ for primary EMPD and secondary EMPD, accurate diagnosis based on detailed histopathological evaluation is required. In the early stages, EMPD usually shows indolent growth, and most cases are diagnosed as carcinoma in situ. However, invasive lesions may result in metastases, and deep invasion is associated with high incidence of metastases. Conventional chemotherapies have been used for EMPD treatment in patients with distant metastases, but the efficacy is not satisfactory, and the prognosis for such patients remains poor. Recent studies have provided various insights into the molecular pathogenesis of the development and advancement of EMPD, which may lead to novel treatment approaches for metastatic EMPD. This review addresses the diagnosis, pathogenesis, and treatment of EMPD with focus on recent progress in understanding this disease.

Abstract
Background This study aimed to investigate the survival analysis of extramammary Paget’s disease (EMPD) in a Taiwanese population and to provide data for comparison with other studies in various locations and racial populations. Methods We retrospectively analyzed the medical records of 63 patients with EMPD who were surgically treated from 2002 to 2019 at a single institution. The primary endpoint was the 5-year overall survival rate of EMPD, and the secondary endpoint was recurrence-free 5-year survival. Independent variables included patients’ demographic data, concurrent malignancy (i.e., non-EMPD-related cancers), tumor size, distant metastasis, and surgery and/or radiation. Results Of all the 63 patients, 8 cases were excluded. A total of 43 patients (78.18%) were male, and 12 were female, with a mean age of 72.67 years (range 44–89 years). The most common affected anatomic site was the penoscrotal region (22 patients, 40.00%), followed by the perianal and perineal regions (17 patients, 30.91%). Among the 55 patients, 41 patients (74.55%) were diagnosed with at least one underlying disease, whereas the most common underlying disease was cardiovascular disease (30 patients, 54.55%). The overall survival rate was 80.00% at 36 months and 65.45% at the end of follow-up. EMPD with deep dermal invasion was a significant poor prognostic factor of overall survival in cause-specific hazard model (sub-hazard ratio (HR) 5.167, p = 0.0015, 95% confidence interval (CI) 1.876–14.230). Patients with regional metastasis or distant metastasis had poorer prognosis of 5-year survival (sub-HR 4.513, p = 0.0028, CI 1.683–12.103). The limitations of this study include its retrospective nature and sample size. Conclusions In our series, EMPD with metastasis and deep dermal invasion was the significant harmful factors in both overall 5-year survival and 5-year recurrence-free survival. The surgical excision is not associated with a low risk of local recurrence or overall survival, and long-term follow-up is still needed.

Abstract
BACKGROUND Extramammary Paget's disease (EMPD) is an intraepithelial adenocarcinoma. The chronic relapsing clinical course and unbearable clinical symptoms of extramammary Paget's disease usually result in a markedly diminished quality of life. No national data are available on descriptive epidemiology of EMPD in China, the most populous country over the world. This population-based study aimed to estimate the prevalence and associated sex and age patterns of EMPD in China. METHODS This study was conducted using data from China's Urban Employee Basic Medical Insurance and Urban Resident Basic Medical Insurance, covering approximately 0.43 billion Chinese urban residents in 2016. Patients with EMPD were identified based on the diagnostic names and codes in claim data. RESULTS A total of 53 males and 31 females with EMPD were found. The crude prevalence in 2016 was 0.04 per 100,000 population [95% confidence interval (CI) 0.02-0.06], ranging from 0.01 (95% CI 0.00-0.02) in North or Northeast China to 0.08 (95% CI 0.03-0.16) in Southwest China. The rate was higher in males (0.05, 95% CI 0.03-0.08) compared with females (0.03, 95% CI 0.02-0.05). The mean age of patients was 65.87 (standard deviation: 14.21) years, with the peak prevalence appeared in patients aged 70-79 (0.28, 95% CI 0.16-0.42). CONCLUSIONS The prevalence of EMPD was markedly lower than those in the United States and Europe, and varied across regions in China. Chinese patients were much younger, with significant male predominance. Further studies are warranted to examine potential pathophysiologic mechanism.

Abstract
BACKGROUND AND OBJECTIVE Extramammary Paget disease (EMPD) has seldom been studied in Mediterranean populations. We aimed to review the characteristics of our patients with EMPD, the presence of a neoplasm in continuity, and the long-term course of the disease. PATIENTS AND METHODS Retrospective observational study of 27 patients diagnosed with EMPD between 1990 and 2015. All clinical and pathology findings related to clinical course and outcomes were retrieved for analysis. RESULTS Twenty patients were women and 7 were men. Ages ranged from 42 to 88 years (median, 76 years). Lesions were in the following locations: vulva (16 cases), pubis-groin (5), perianal region (4), and axilla (2). Time from onset to diagnosis ranged from 1 to 60 months (median, 12 months) and maximum lesion diameter from 20 to 140mm (median, 55mm). In 3 cases (11.1%) EMPD was a secondary condition. None of the lesions developed on a previous cutaneous adnexal adenocarcinoma. Ten of the 24 primary EMPDs (41.7%) invaded the dermis. Eight of the 27 patients (29.6%) experienced local recurrence after the initial surgical treatment.Three patients (11.1%) died as a consequence of metastasis from the EMPD. CONCLUSIONS The presence of an underlying cutaneous adnexal adenocarcinoma is uncommon, but it is not unusual to find an extracutaneous adenocarcinoma in continuity. Although EMPD is a slow-growing tumor, dermal invasion is frequent and metastasis is not uncommon. Local recurrence is common even after excision with wide margins and may be delated, so long term follow-up is essential.

Abstract
OBJECTIVE To assess the incidence, treatment, and outcomes in patients with invasive vulvar extramammary Paget's disease (EMPD) in a national cohort of patients. METHODS Patients from the Surveillance, Epidemiology and End Results (SEER) database with diagnoses of vulvar EMPD from 1992 to 2016 were included. Demographic, treatment, and outcome data were analyzed. RESULTS A total of 1268 cases of invasive EMPD were identified. Of those, 69.6% had localized disease, 12.0% regional disease, 1.3% distant disease, and 17.1% were unstaged. The annual incidence of invasive vulvar EMPD was 0.36 per 100,000 person years: rates have increased >2-fold since 1992 (1992: 0.19 per 100,000 person years to 0.50 per 100,000 person years in 2016). Most patients underwent primary surgery (n = 1034; 81.5%). Five-year cancer specific survival (CSS) was 95.5% and was associated with stage. Compared to patients with localized disease, patients with distant metastases had dramatically worse CSS (HR: 85.8 (31.8-248) p < 0.0001). Synchronous cancers (diagnosed within one calendar year of EMPD diagnosis year) were observed in 35 cases (2.8%), and 195 patients (15.4%) developed a secondary malignancy (diagnosed >one year from year of EMPD diagnosis year). The most common synchronous breast, gastrointestinal tract, melanoma and the most common secondary cancers were breast, gastrointestinal tract and genitourinary tract. CONCLUSIONS The incidence of invasive vulvar EMPD has increased over time. CSS is excellent for localized disease, but those with metastatic disease are in need of novel therapies. Approximately 15% will develop a secondary malignancy, indicating that patients with invasive vulvar EMPD should undergo site specific preventative health screens during recurrence surveillance.

Abstract
Extramammary Paget's disease (EMPD) is a rare and lethal intraepithelial malignancy that remains poorly understood. No standardized guidelines or consensus statements exist with regards to the diagnostic evaluation, therapeutic approaches and follow-up management. Complete surgical excision with negative margins has been accepted as the mainstay of treatment for EMPD to decrease the risk of local recurrence and to maximize durable cure. Non-invasive therapies, such as laser therapy, photodynamic therapy, radiotherapy and topical chemotherapy have been utilized, but are best reserved for non-surgical candidates. While the debate on the surgical approach between wide local excision (WLE) and Mohs micrographic surgery (MMS) continues, several studies have demonstrated the ability of WLE to be performed safely and effectively and to yield equally satisfactory outcomes with similar rates of recurrence to MMS. Patients undergoing surgical excision often require complex closures with skin grafting or local flaps to close genital defects. We aim to provide an up-to-date review of the current knowledge of EMPD. In addition to discussing the clinical presentation and prognostic outcomes, we focus and elaborate on the diagnostic approaches and treatment alternatives available. This information may serve as a primer for the urologist who may be called upon to treat this malignancy primarily or to provide wound coverage secondarily.

Abstract
Extramammary Paget disease (EMPD) is a rare cutaneous adenocarcinoma of the anogenital region most commonly treated with surgical excision. Surgical margin clearance is often problematic and recurrence rates remain high indicating the need for additional therapeutic options. Topical immunomodulators have been used with reported success suggesting EMPD may respond to other immunotherapies. This study investigates EMPD protein expression of targetable B7 family members and cancer/testis antigens (CTAs) B7-H3, B7-H4, PD-L1, PD-L2, MAGE-A, and NY-ESO-1 and components of antigen presenting machinery B2M and MHC-I. Fifty-seven specimens from 48 patients (31 female and 17 male), representing in situ, invasive, and metastatic disease of primary and secondary origin were stained and scored (627 total slides). The percentage of cases expressing each immune regulatory molecule in the in situ followed by invasive tumor components was: B7-H3 (94, 90), B7-H4 (82, 78), PD-L1 (6, 10), MAGE-A (39, 50), NY-ESO-1 (16, 20), B2M (100, 89), and MHC-I (78, 79). PD-L2 was negative in all cases. There was high correlation between marker expression within the in situ and invasive tumor components of the same case. B7-H4 was preferentially expressed in primary cutaneous EMPD. Co-expression of B7 family members B7-H3 and B7-H4 was found within the in situ and invasive tumor components of 74% and 48% of cases, respectively. These findings provide an initial characterization of EMPD tumor cell expression of B7-H3, B7-H4, PD-L1, PD-L2, MAGE-A, and NY-ESO-1 and indicate the potential for new immunotherapeutic options for patients with EMPD.

Abstract
OBJECTIVE To describe our surgical experience for the treatment and management of extramammary Paget's disease (EMPD). METHODS Our surgical approach involves excising a 2-cm margin of normal appearing skin around the EMPD-suspicious lesion. Prior to excision, the tissue is oriented and demarcated into predefined segments in coordination with a pathologist. Frozen sections are performed when necessary to guide additional excision. Xenograft or wet-to-dry dressings are applied depending on size and location of the wound while the specimen is expeditiously reviewed over the following 24-48 hours. If positive margins remain, further excision of the corresponding skin segment is performed. Delayed complex wound closure +/- split thickness skin grafting is performed once negative margins are confirmed. RESULTS Ten EMPD patients were referred to two academic centers between 2014 and 2018. Two patients had positive lymph nodes at diagnosis and underwent palliative surgery and died within 12 and 29 months. The remaining 8 patients underwent a median of 1 surgery (range 0-3) with referring providers before undergoing a median of 3 surgeries (range 2-5) at our institutions to achieve negative surgical margins and wound reconstruction (7 split thickness skin grafts, 1 secondary closure). At mean follow-up of 15 months, 1 patient recurred, required further excision, and remains disease free. CONCLUSION EMPD is a rare malignancy with poorly described treatment methodologies. Due to its multifocal distribution and asymmetric spread, obtaining negative margins can be challenging. Our systematic approach to obtaining wide margins and documenting excised skin has enabled us to achieve negative margins for this challenging malignancy.

Abstract
Paget's disease (PD) is an uncommon intraepithelial adenocarcinoma with unknown pathogenesis. There are two anatomic subtypes: mammary (MPD) and extramammary (EMPD). Little is known about their molecular characteristics. Our objective was to discover novel molecular markers for PD and its subtypes. In the discovery phase, we used transcriptome analyses to uncover the most differentially expressed genes and pathways in EMPD biopsies compared with normal skin. In the validation phase, we performed immunohistochemistry analyses on the most promising marker (FOXA1) and other markers selected from a literature review (GATA3, estrogen receptor [ER], and androgen receptor [AR]) on independent biopsies of MPD (n = 86), EMPD (n = 59), and normal skin (n = 21). Transcriptome analyses revealed 210 genes differentially expressed more than 10-fold between EMPD and normal skin. These genes are involved in mammary and sweat gland development (FOXA1) and immune regulation, as well as epidermal differentiation. Immunohistochemistry staining revealed that FOXA1 was positive in 88% of both MPD and EMPD, whereas GATA3 was positive in 67% of MPD and 77% of EMPD, and ER was positive in 9% of MPD and 19% of EMPD. Finally, AR was positive in 33% of PD and 54% of EMPD. Mammary Paget's disease and EMPD share dysregulation of the glandular developmental regulator gene FOXA1, suggesting similarity in cell-specific transcriptional regulation. Further, FOXA1 may be a useful molecular target for developing PD therapies.

Abstract
Advanced extramammary Paget's disease does not have a standardized treatment guideline as its incidence is low and has been rarely reported in literature. Here we describe a case of metastatic extramammary Paget's disease successfully treated with topical 5-fluorouracil (5-FU) and systemic pemetrexed. The therapy was safe without any appreciable adverse effects like diarrhea, rash, neutropenia or fatigue; maintaining remission for more than 6 months. Thus, we propose 5-FU and pemetrexed as the first-line therapy for advanced extramammary Paget's disease, especially for aged patients with unresectable skin lesions.

Abstract
OBJECTIVE To illustrate the heterogeneous care delivered to patients with extramammary Paget disease (EMPD), a rare and lethal malignancy with poorly described treatment methodologies, by characterizing the clinical and pathologic characteristics of an international patient support group. MATERIALS AND METHODS Institutional review board approval was obtained to develop and distribute a nonvalidated survey to patients from an international, online EMPD support group. The survey was developed to capture patient clinical and pathologic details and was distributed between January 2017 and February 2017. RESULTS Forty-two patients completed the survey. At a mean age of 64 years, patients most commonly developed rash, pruritus, or erythema in the genital and perianal regions. Patients presented to their primary care physician, gynecologist, or dermatologist and were initially treated with topical agents for benign diagnoses. After failing conservative treatments, patients underwent biopsy by a dermatologist or gynecologist and were diagnosed with EMPD on average 21 months after the onset of symptoms. Wide local and Mohs excisions were the most frequently administered treatments with positive margins reported in 43% of patients. Fewer patients underwent noninvasive treatment with imiquimod cream and radiation. In total, 29% of patients developed regional recurrence and distant disease. There was wide variation regarding medical specialties involved, diagnostic evaluation, treatment, and clinical follow-up. CONCLUSION This study provides a novel view of the varied clinical and pathologic details from patients treated across varying institutions and medical specialties. This study will hopefully educate providers of the overall disease process of EMPD and encourage the development of standardized treatment recommendations.

Abstract
Artesian well-water had high concentrations of arsenic that led to the well-known black foot disease in Taiwan around the 1950s, and the associated cancers including skin cancer, bladder cancers and lung cancers. We sought to estimate the standardized morbidity ratio (SMR) and age-standardized incidence rate (ASIR) of cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) in the black foot disease endemic areas (BFDEA) in Taiwan. A nationwide retrospective population-based survey was done with the data from the National Taiwan Cancer Registry Center between 1979 and 2007. Among the 29-year period, there were 11 191 cases with SCC and 13 684 cases with BCC diagnosed pathologically. The incidence rates were 4-6-fold higher for SCC and 3-4-fold higher for BCC in the BFDEA compared with the rest of Taiwan. The SMR decreased after stopping arsenic-containing well-water drinking in the 1970s. The arsenic level in the drinking water, amount of contaminated water intake, occupation and sun-exposure time were not documented. This is the first nationwide, population-based study that shows the relationship between arsenic intoxication and non-melanoma skin cancers (SCC and BCC) through comparing the data in people living in the BFDEA and non-BFDEA in Taiwan.

Abstract
Metastatic extramammary Paget's disease (EMPD) is a rare cancer with no validated systemic treatment. Regimens including FECOM 5-fluorouracil (5-FU, epirubicin, carboplatin, vincristine and mitomycin C), 5-FU/cisplatin and single agent docetaxel exhibited varying levels of efficacy in case reports. A 58-year-old man with EMPD diffusely metastatic to bone presented with worsening shortness of breath, significant pancytopenia and disseminated intravascular coagulation (DIC). He was started on low-dose heparin for the DIC and weekly paclitaxel. Initially requiring almost daily transfusions, his shortness of breath improved after two doses of paclitaxel, and he became transfusion-independent after only three doses. Correlating with his disease course, the patient's prepaclitaxel carcinoembryonic antigen level of 62.1 ng/mL decreased to 7.4 ng/mL on 3-month follow-up, and he showed no progression of disease on imaging. With no validated chemotherapy regimen currently, this case can help guide consideration of paclitaxel in future treatment of metastatic EMPD.
