A Case of Advanced Extramammary Paget’s Disease With a High Tumor Mutation Burden That Showed Partial Lymph Node Regression With Pembrolizumab

Pembrolizumab has been found effective against various solid tumors with high tumor mutation burden, but there are no reports of successful treatment with pembrolizumab for extramammary Paget's disease (EMPD) with a high tumor mutation burden (TMB). This report describes a 71-year-old male patient who presented with irregularly shaped erythematous lesions on his scrotum, which had been there for several years. He was diagnosed with EMPD. A gene panel test indicated a high TMB. Six months after radical surgery, many lymph node metastases were found. We started a combination chemotherapy of tegafur-gimeracil-oteracil potassium (TS-1) and docetaxel. After three courses, a CT scan showed reductions in the sizes of all the metastatic lesions. However, the treatment was switched to pembrolizumab at the patient’s request. After four cycles of the pembrolizumab treatment, a CT scan showed further shrinkage in most of the lymph node metastases. As far as we know, the present patient is the first case of advanced EMPD with response to pembrolizumab monotherapy.

FOXM1: a new therapeutic target of extramammary Paget disease

Extramammary Paget disease (EMPD) is a rare skin cancer that primarily affects older individuals predominantly in areas with apocrine sweat glands. Although most early EMPD lesions are indolent, patients with metastatic EMPD have a poor prognosis due to the lack of effective systemic treatment. In this study, we investigated the role of forkhead box M1 (FOXM1), a potent transcription factor, in EMPD and assessed the potential of FOXM1 as a therapeutic target. Immunohistochemistry of 112 primary and 17 metastatic EMPD samples revealed that FOXM1 expression increased with tumor progression. Patients in whom FOXM1 was expressed in more than 10% of tumor cells had significantly shorter disease-specific survival than the other patients (p = 0.0397). In in vitro studies using our newly established EMPD cell line, KS-EMPD-1, we found high expression of FOXM1. Knockdown of FOXM1 impaired tumor cell viability, migration, and invasion. Inhibition of FOXM1 using thiostrepton also reduced tumor cell viability in a dose-dependent manner. These findings suggest that FOXM1 is a promising therapeutic target for patients with EMPD.

Treatment outcomes of advanced/metastatic extramammary Paget's disease in Korean patients

Extramammary Paget's disease (EMPD) is rare. There are no standard treatments due to its rarity and few clinical trials. 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. 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.

Efficacy of chemotherapies for unresectable extramammary Paget disease: a single-centre retrospective study

Extramammary Paget disease (EMPD) is a cutaneous neoplasm that can metastasise to the lymph nodes and distant organs, resulting in a poor prognosis. For unresectable distant metastases of EMPD, no consensus has been reached regarding the optimal chemotherapy owing to the lack of data. Further investigations with prospective analysis are required to confirm these findings.

Efficacy of Abemaciclib in the Management of Refractory Metastatic Extramammary Paget’s Disease

Published systemic therapy options for metastatic extramammary Paget's disease have largely been anecdotal due to the rarity of this disease, which has precluded the ability to conduct clinical trials. We describe the favorable response of a 72-year-old man with extramammary Paget's disease, whose disease has been controlled with the CDK4/6 inhibitor, abemaciclib. The rationale behind the selection of this therapy is discussed.

The efficacy and survival impact of conventional chemotherapies for metastatic extra- mammary Paget’s disease (EMPD) have not been fully elucidated. This study examined the long- term outcome of chemotherapy for this indication. We conducted a retrospective review of 21 pa- tients with distant metastatic EMPD (14 patients treated with chemotherapy and 7 patients treated without chemotherapy). The response rate of chemotherapy and patient survival were statistically analyzed.

Topical Combination of Fluorouracil and Calcipotriene as a Palliative Therapy for Refractory Extramammary Paget Disease.

Extramammary Paget disease (EMPD), a rare intraepithelial adenocarcinoma, poses a therapeutic challenge with high postoperative recurrence rates and a limited number of effective local treatment options. This retrospective case series of 3 women with recurrent, refractory EMPD was conducted at Beth Israel Deaconess Medical Center, Boston, Massachusetts and Washington University School of Medicine, St Louis, Missouri. All patients were treated with a 1:1 mixture of fluorouracil, 5%, cream and calcipotriene, 0.005%, cream or ointment.

Combination Cisplatin‐Epirubicin‐Paclitaxel Therapy for Metastatic Extramammary Paget's Disease

Combination Cisplatin‐Epirubicin‐Paclitaxel Therapy for Metastatic Extramammary Paget's Disease

xtramammary Paget's disease (EMPD) is a rare cutaneous adenocarcinoma that clinicopathologically resembles breast cancer. The prognosis of metastatic EMPD is poor. Although several chemotherapies have been tried, the effects are temporary; better drugs and combinations are required.

In the present study, we retrospectively analyze the efficacy and safety of combination of cisplatin, epirubicin, and paclitaxel in five metastatic EMPD cases. The efficacy was better than that for previously reported regimens: 80% partial responses, including two patients who were refractory to taxane‐ and/or platinum‐based regimens. In terms of safety, four patients who were able to continue treatment exhibited acceptable tolerability.

Anal canal adenocarcinoma with neuroendocrine features accompanying secondary extramammary Paget disease, successfully treated with modified FOLFOX6: a case report

Anal canal cancer occasionally accompanies extramammary Paget disease. Although most of them are squamous cell carcinoma, anal canal adenocarcinoma with neuroendocrine features accompanying secondary extramammary Paget disease has never been reported.

This is a clinically significant case, as it reveals novel pathological features about anal canal cancer with secondary Paget disease and successfully treated with modified FOLFOX6. Careful pathological investigation and appropriate treatment choice are needed for this rare cancer.

Paget Disease, Extramammary

Extramammary Paget disease (EMPD) is a rare dermatologic condition that frequently presents in areas where apocrine sweat glands are abundant, most commonly the vulva, although perineal, scrotal, perianal, and penile skin may also be affected. Lesions clinically present as erythematous, well-demarcated plaques that may become erosive, ulcerated, scaly, or eczematous. Extramammary Paget disease has a female predominance and usually occurs in the sixth to eighth decades of life. Professionals disagree about many aspects of EMPD, for example, the prevalence of concurrent vulvar adenocarcinoma or invasive EMPD, association with regional and distant cancers, and recurrence rates following surgical excision. Early recognition is imperative because the diagnosis is frequently delayed and there is a high incidence of associated invasive disease.

Successful treatment of metastatic extramammary Paget's disease with pemetrexed monotherapy systemically and 5-fluorouracil topically

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.

Efficacy of low-dose 5-fluorouracil/cisplatin therapy for invasive extramammary Paget’s disease

Extramammary Paget's disease (EMPD) is one of the cutaneous adenocarcinomas. The effective chemotherapy for advanced EMPD has not been established. This study was designed to evaluate the efficacy of combination 5‐fluorouracil (500 mg/body, 7 days/week) and cisplatin (5 mg/body 5 days/week) for invasive EMPD. Seventeen EMPD patients with multiple metastases who visited our dermatology clinic between October 2004 and May 2016 (mean age, 76.9 years; 10 men, seven women) were retrospectively analyzed. Eight EMPD patients underwent low‐dose 5‐fluorouracil/cisplatin therapy and nine patients chose best supportive care. The average number of treatment cycles was 12.3. All patients had a confirmed response, four (50%) showed a partial response, two (25%) stable disease and two progressive disease. The median times to progression‐free and overall survival were 25.0 and 77.4 weeks, respectively. There was no severe (grade 3 and 4) adverse event. Although not significant, the survival of the patients treated with low‐dose 5‐fluorouracil/cisplatin therapy showed a trend toward improved survival as compared with best supportive care (P = 0.08, log–rank test). This regimen had low risk and relatively high disease control rate, suggesting that this regimen be recommended as one of the treatment options for advanced EMPD.

Metastatic extramammary Paget's disease responding to weekly paclitaxel.

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.

We retrospectively analyzed the efficacy of combination chemotherapy consisting of infusions of 5-fluorouracil (5-FU, 600 mg/m2/body, 5 days/week) and cisplatin (5–10 mg/body, 5–7 days/week) administered intravenously for 8–24 h (low-dose FP). The overall survival ranges (medians) were 5–51 months (12) in all 22 patients, 6–51 months (13) in the 13 patients showing complete response or PR, and 5–12 months (11) in the 6 SD patients. The reported palliative effects of low-dose FP include control of pain and improvement of lymphedema.

Metastatic extramammary Paget’s disease with pancytopenia and disseminated intravascular coagulation responding to weekly paclitaxel: a case report

Metastatic Extramammary Paget’s Disease (EMPD) is a rare cancer that currently has no validated treatment. Regimens including FECOM (5-FU, epirubicin, carboplatin, vincristine, and mitomycin C), trastuzumab in HER-2 expressing disease, 5-FU/cisplatin, or single agent docetaxel have been used in different case reports with varying levels of efficacy. A 58 year-old gentleman with EMPD diffusely metastatic to bone with bone marrow invasion presented with worsening shortness of breath and was found to have significant pancytopenia and disseminated intravascular coagulation (DIC). He was started on low-dose heparin for the DIC and weekly paclitaxel. Initially requiring daily transfusions of platelets and packed red blood cells, his shortness of breath improved after two doses of paclitaxel, and he became transfusion-independent after only three doses of paclitaxel. Carcinoembryonic Antigen (CEA) levels have been shown to correlate with tumor progression and parallel disease course. This patient’s pre-paclitaxel CEA of 62.1 ng/mL was also observed to decrease to 20.6 ng/mL after three doses. With no current validated chemotherapy regimen, this case can help guide consideration of paclitaxel in future treatment of metastatic EMPD.

Successful Intra-Arterial Chemotherapy for Extramammary Paget’s Disease of the Axilla in a Patient with Parkinson’s Disease

Extramammary Paget’s disease (EMPD) is a rare intraepithelial neoplasm occurring less frequently in men and even more rarely in the axilla. A 59-year-old man with severe Parkinson’s disease presented with axillary EMPD. The neurological comorbidity made treatment of the EMPD problematical and prompted us to propose locoregional intra-arterial chemotherapy in single short sessions. Two innovative chemotherapeutic macrocomplexes were used: doxorubicin incorporated in large liposomes and the taxane paclitaxel incorporated in albumin nanoparticles. A therapeutic response was seen right from the first treatment and was macroscopically close to complete after four cycles. Five months after the end of treatment the patient had minimal visible disease and had enjoyed a distinct improvement in quality of life, with no noteworthy complications related to the intra-arterial chemotherapy with percutaneous transfemoral catheterization.
