RESUMO
Background: Anti-programmed cell death protein 1 (PD-1) monotherapy is one of the standard systemic therapies for advanced melanoma; however, the efficacy of salvage systemic therapies after PD-1 monotherapy failure (PD-1 MF), particularly in acral melanoma (AM), the main clinical melanoma type in Japanese patients, is unclear. This study aimed to investigate the efficacy of salvage systemic therapies in Japanese patients with AM after PD-1 MF. Patients and methods: The study included 108 patients with advanced AM (palm and sole, 72; nail apparatus, 36) who underwent salvage systemic therapy at 24 Japanese institutions. We mainly assessed the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). Results: Thirty-six (33%) patients received ipilimumab, 23 (21%) received nivolumab and ipilimumab (nivo/ipi), 10 (9%) received cytotoxic chemotherapy, 4 (4%) received BRAF and MEK inhibitors (BRAFi/MEKi), and the remaining 35 (32%) continued with PD-1 monotherapy after disease progression. The ORRs in the ipilimumab, nivo/ipi, cytotoxic chemotherapy, and BRAFi/MEKi groups were 8, 17, 0, and 100%, respectively. The nivo/ipi group showed the longest OS (median, 18.9 months); however, differences in ORR, PFS, and OS between the groups were insignificant. The OS in the nivo/ipi group was higher in the palm and sole groups than in the nail apparatus group (median: not reached vs. 8.7 months, p < 0.001). Cox multivariate analysis demonstrated that nail apparatus melanoma independently predicted unfavorable PFS and OS (p = 0.006 and 0.001). The total OS (from PD-1 monotherapy initiation to death/last follow-up) was insignificant between the groups. Conclusion: Nivo/ipi was not more effective than cytotoxic chemotherapy and ipilimumab after PD-1 MF in patients with advanced AM. The prognosis after PD-1 MF would be poorer for nail apparatus melanoma than for palm and sole melanoma.
RESUMO
Japanese patients with very high-risk cutaneous squamous cell carcinomas (cSCCs), based on the National Comprehensive Cancer Network guidelines, have been reported to display a higher cumulative incidence of relapse and disease-specific death (DSD) than those with high-risk cSCC. Therefore, prognosis prediction is crucial for Japanese patients with very high-risk cSCCs. Herein, we aimed to evaluate the prognostic prediction ability of our novel Japanese Risk Factor Scoring Systems (JARF scoring) in a Japanese cohort of cSSC patients. Data of 424 Japanese patients with resectable very high-risk cSCCs were analysed. We compared the prognostic ability of the following three staging systems: Brigham and Women's Hospital (BWH) tumour staging, number of NCCN very high-risk factors, and JARF scoring, including recurrent tumour, high-risk histological features, deep tumour invasion and lymphatic or vascular involvement as risk factors. The prognostic ability of these staging systems was evaluated according to the cumulative incidence of local recurrence (LR), regional lymph node metastasis (RLNM), DSD, and overall survival (OS). When BWH staging was used, high T stage led to significantly poor outcomes only in the cumulative incidence of RLNM (p = 0.01). The presence of very high-risk NCCN factors led to significantly poor outcomes in terms of RLNM (p = 0.03) and OS (p = 0.02). Meanwhile, a high number of risk factors in the JARF scoring system clearly led to poor outcomes in terms of LR (p = 0.01), RLNM (p < 0.01), DSD (p = 0.03), and OS (p < 0.01). The JARF scoring system may accurately predict the risk of recurrence and death in very high-risk cSCC patients in Japan.

BACKGROUND: Although anti-PD-1 antibody monotherapy (PD-1) is commonly used to treat advanced acral melanoma (AM), its efficacy is limited. Further, data on the efficacy of PD-1 plus anti-CTLA-4 antibody (PD-1+CTLA-4) for the treatment of AM are limited. Therefore, we compared the efficacy of PD-1+CTLA-4 and PD-1 in the treatment of Japanese patients with advanced AM. METHODS: This retrospective study evaluated patients with advanced AM who were treated with PD-1 or PD-1+CTLA-4 as first-line immunotherapy in 24 Japanese institutions between 2014 and 2020. Treatment efficacy focussing on the objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) was compared between the two groups. RESULTS: In total, 254 patients (palm and sole melanoma [PSM], n = 180; nail apparatus melanoma [NAM], n = 74) were included. Among the patients with PSM, the ORR (19% vs. 31%; P = 0.44), PFS (5.9 vs. 3.2 months; P = 0.74), and OS (23.1 vs. not reached; P = 0.55) did not differ significantly between the PD-1 and PD-1+CTLA-4 groups. Among the patients with NAM, the ORR (61% vs. 10%; P < 0.001) was significantly higher and PFS was longer (6.4 vs. 3.8 months; P = 0.10) in the PD-1+CTLA-4 group than in the PD-1 group. Cox multivariate analysis demonstrated that PD-1+CTLA-4 is an independent predictor of a favourable PFS in patients with NAM (P = 0.002). CONCLUSIONS: The efficacy of PD-1+CTLA-4 is not superior to that of PD-1 for the treatment of advanced PSM. However, PD-1+CTLA-4 may be more efficacious than PD-1 for the treatment of advanced NAM.

In older patients with facial basal cell carcinoma (BCC) or squamous cell carcinoma (SCC), surgery should be aimed to reduce treatment-related sequelae and burden with achieving local tumor care. Therefore, we adopted a two-step surgery (TSS) involving the application of a dermal regeneration template onto the skin defect after tumor resection and subsequent reconstruction by full-thickness skin grafting. We performed a detailed comparison of conventional one-step surgery (OSS) and TSS, including evaluation of local tumor curability, postoperative cosmetic and/or functional impairments, and patient burden. Forty-six patients who underwent TSS and 104 patients treated with OSS were retrospectively investigated. The cohort consisted of 77 men and 73 women (median age, 83â years). The BCC: SCC ratio was 56.7%: 43.3%. The tumor size and excision margin were significantly larger in the TSS group than in the OSS group (p = 0.03). The histopathological margin was positive after the first surgery in six cases, but was negative after additional resection in all cases, regardless of OSS or TSS. Local recurrence was not observed in this study. The frequency of postoperative sequelae (POS) in TSS was slightly lower than in OSS (17.4% vs. 27.9%, p = 0.16). A shorter average operation time per session was significantly associated with the location of the vertical defect [below adipose tissue vs. within adipose tissue, estimate: -0.28 (hour), p < 0.001] and surgical procedure [OSS vs. TSS, estimate: -0.13 (hour), p = 0.03] by multiple regression models. The ratio of general anesthesia was relatively lower in TSS than in OSS (9.8% vs. 17.3%, p = 0.12). Thus, TSS showed a good local curability and POS statistically equivalent to OSS, reducing the surgical burden, particularly shortening each operation time without any adverse events, despite the TSS group having significantly larger tumors than the OSS group. Since TSS is a simple procedure, it can be an outstanding option for facial BCC and SCC.
RESUMO
BACKGROUND AND OBJECTIVES: In cutaneous squamous cell carcinoma (cSCC), adherence to guideline-recommended fixed surgical margins is often difficult, and narrower margins are preferable. This study aimed to evaluate relapse and disease-specific death with narrower margins for high or very high-risk cSCC. PATIENTS/METHODS: We retrospectively investigated high or very high-risk cSCC patients who underwent tumor excision. Patients were divided into guideline-recommended standard margin group (SMG) and narrower-margin group (NMG). Co-primary outcomes were local relapse, SCC relapse, and SCC death. Cumulative incidence function (CIF) was used to describe SCC death probability and competing risk mortality. Gray's test was used to compare differences in CIF between the groups. RESULTS: In total, 1,000 patients with cSCC (high-risk, 570; very high-risk, 430) were included. In the high-risk cohort, there were no significant differences in incomplete excision rate (IER) between SMG and NMG (2.6 % vs. 3.0 %, P > 0.99). However, in the very high-risk cohort, IER in SMG was significantly lower than in NMG (8.9 % vs. 16.2 %, P = 0.03). No significant differences were observed between SMG and NMG for local relapse (high-risk, P = 0.56; very high-risk, P = 0.70), SCC relapse (high-risk, P = 0.30; very high-risk, P = 0.47), and SCC death (high-risk, P = 0.23; very high-risk, P = 0.83). CONCLUSIONS: Surgical margin size has limited impact on margin control, relapse, and disease-specific death in high-risk cSCC.

HINTERGRUND UND ZIELE: Bei kutanen Plattenepithelkarzinomen (PEK) ist die Einhaltung der in Leitlinien empfohlenen festen Resektionsränder oft schwierig und knappere Ränder sind wünschenswert. Ziel dieser Studie war die Bewertung des Auftretens von Rezidiven und krankheitsspezifischen Todesfällen bei knapperen Resektionsrändern für PEK mit hohem oder sehr hohem Risiko. PATIENTEN/METHODEN: PEK-Patienten mit hohem oder sehr hohem Risiko, bei denen eine Tumorexzision durchgeführt wurde, wurden retrospektiv untersucht. Die Patienten wurden in eine Gruppe mit Standardrand gemäß Leitlinienempfehlung (standard margin group, SMG) und eine Gruppe mit knapperen Rändern (narrower-margin group, NMG) eingeteilt. Gemeinsame primäre Endpunkte waren lokales Rezidiv, PEK-Rezidiv und PEK-bedingter Tod. Die Wahrscheinlichkeit eines PEK-bedingten Tods und konkurrierender Mortalitätsrisiken wurde mittels kumulativer Inzidenzfunktion (CIF) beschrieben. Unterschiede bei der CIF zwischen den Gruppen wurden mit dem Test nach Gray verglichen. ERGEBNISSE: Insgesamt wurden 1.000 Patienten mit PEK (hohes Risiko, 570; sehr hohes Risiko, 430) eingeschlossen. In der Kohorte mit hohem Risiko gab es keine signifikanten Unterschiede bei der unvollständigen Exzisionsrate (IER) zwischen SMG und NMG (2,6 % vs. 3,0 %, P > 0,99). In der Kohorte mit sehr hohem Risiko war die IER in der SMG jedoch signifikant geringer als in der NMG (8.9 % vs. 16.2 %, P = 0,03). Keine signifikanten Unterschiede zwischen SMG und NMG wurden für Lokalrezidiv (hohes Risiko, P = 0.56; sehr hohes Risiko, P = 0,70), PEK-Rezidiv (hohes Risiko, P = 0,30; sehr hohes Risiko, P = 0,47) und PEK-bedingtem Tod (hohes Risiko, P = 0,23; sehr hohes Risiko, P = 0,83) beobachtet. SCHLUSSFOLGERUNGEN: Die Größe des Resektionsrands hat einen begrenzten Einfluss auf Randkontrolle, Rezidive und krankheitsspezifischen Tod bei PEK mit hohem Risiko.
RESUMO
Skin cancer patients with clinical nodal disease or whose positive sentinel nodes had great tumor burden remain candidates for regional lymph node dissections. Among these patients, inguinal or ilioinguinal lymph node dissection is frequently required in clinical practice, which is associated with significant postoperative morbidity-including lymphatic leakage. The aim of this retrospective study was to evaluate the efficacy of LigaSure™, an electrothermal bipolar vessel sealing system, in reducing lymphatic leakage in inguinal or ilioinguinal lymph node dissection. In total, 58 patients who received inguinal or ilioinguinal lymph node dissection (conventional group, 48; LigaSure™ group, 10) and shared similar characteristics were included in this study. Lymphatic leakage after drain removal was significantly lower in the LigaSure™ group than that in the conventional group (present ratio, 0% vs. 37%; p = 0.02). The daily lymphatic drainage volume also tended to be lower in the LigaSure™ than that in the conventional group, with significant differences on postoperative day 1 (p = 0.02). Other perioperative outcomes including the operating time, intraoperative blood loss, time to drain removal, duration of hospital stay, flap necrosis, and wound infection showed no significant differences between the two groups. The use of the LigaSure™ in inguinal or ilioinguinal lymph node dissection for the treatment of skin cancer could reduce the incidence of postoperative lymphatic leakage after drain removal.

An 85-year-old man was being treated with anti-cancer drugs for adenocarcinoma of the lung and was on a tapering dose of prednisolone for interstitial pneumonia. He attended our hospital complaining of fatigue, thirst, and polyuria in September 2020. His postprandial plasma glucose concentration was 976 mg/dL, his glycated hemoglobin was 8.0%, his plasma osmolality was 342 mOsm/kg H2O, his urine ketone body content was 1 +, and his blood pH was 7.356. Therefore, we diagnosed a hyperosmolar-hyperglycemic state and he was admitted to the hospital for treatment. He had had no previous upper respiratory symptoms, and his postprandial plasma glucose and glycated hemoglobin were normal 13 days before he was first assessed (90 mg/dL and 5.9%, respectively). On admission, his serum pancreatic exocrine enzyme activities were high and he was negative for islet-specific autoantibodies. His serum C-peptide concentration was 0.60 ng/mL, suggesting that his endogenous insulin secretion was partially intact at that time. Although he did not meet the diagnostic criteria, we suspected him of having fulminant type 1 diabetes mellitus, because of the abrupt onset of hyperosmolar-hyperglycemic state. His general condition was improved by fluid and insulin administration. His human leukocyte antigen genotype was DRB1*04:05 DQB1*04:01:01, which is a disease susceptibility haplotype for fulminant type 1 diabetes mellitus. In addition, his prednisolone treatment may have caused an autoimmune abnormality, further predisposing toward the development of fulminant type 1 diabetes mellitus.
RESUMO
BACKGROUND: Immune checkpoint inhibitors (ICIs) have a lower efficacy in mucosal melanoma (MUM) than in cutaneous melanoma. The use of combination treatments with radiotherapy (RT) to improve the efficacy in MUM, however, requires further investigation. METHODS: We retrospectively evaluated 225 advanced MUM patients treated with anti-PD-1 monotherapy (PD1; 115) or anti-PD-1 + anti-CTLA-4 combination therapy (PD1+CTLA4; 42) with or without RT (56 and 12, respectively). Treatment efficacy was estimated by determining the objective response rate (ORR) and survival rate with the Kaplan-Meier analysis. RESULTS: The baseline characteristics between the two groups in each ICI cohort were similar, except for Eastern Cooperative Oncology Group performance status in the PD1 cohort. No significant differences in ORR, progression-free survival (PFS), and overall survival (OS) were observed between the PD1 alone and PD1+RT groups in the PD1 cohort (ORR 26% versus 27%, P > 0.99; median PFS 6.2 versus 6.8 months, P = 0.63; median OS 19.2 versus 23.1 months, P = 0.70) or between the PD1+CTLA alone and PD1+CTLA4+RT groups in the PD1+CTLA4 cohort (ORR 28% vs 25%, P = 0.62; median PFS 5.8 versus 3.5 months, P = 0.21; median OS 31.7 versus 19.8 months, P = 0.79). Cox multivariate analysis indicated that RT in addition to PD1 or PD1+CTLA4 did not have a positive impact on the PFS or OS. CONCLUSIONS: A prolonged survival benefit with RT in combination with ICIs was not identified for advanced MUM patients, although RT may improve local control of the tumour and relieve local symptoms.

A silent pituitary adenoma (SPA) is characterized by the expression of pituitary hormones, detected by immunohistochemical staining, in the absence of clinical signs or symptoms of hormonal excess. Compared with functional pituitary adenomas, little is known regarding the involvement of SPAs in metabolic disorders. This study aimed to examine the correlations between SPAs and metabolic disorders, including obesity, abnormal glucose tolerance, hypertension and dyslipidemia. Seventy-four patients with nonfunctional pituitary adenomas who underwent a pituitary adenomectomy in Hokkaido University Hospital from 2008 to 2016 were retrospectively examined. Pituitary adenomas were immunohistochemically classified into pituitary hormone positive or negative groups. Twenty whole hormone-negative pituitary adenomas were excluded because we couldn't identify pituitary transcription factors which is necessary for the diagnosis of a null cell adenoma. The preoperative rates of obesity, abnormal glucose tolerance, hypertension and dyslipidemia were compared between each group. Twenty-seven GH positive adenomas (50.0%), 32 gonadotroph positive adenomas (59.3%), 28 TSH positive adenomas (51.9%) and 21 ACTH positive adenomas (38.9%) were identified. Evaluation of the preoperative clinical data showed 25 cases of obesity (46.2%), 16 cases of abnormal glucose tolerance (29.6%), 29 cases of hypertension (53.7%) and 35 cases of dyslipidemia (64.8%). The rate of hypertension was significantly lower in the GH positive group (37.0%) than the GH negative group (70.4%) (p = 0.0140). In the GH negative group, postoperative systolic and diastolic blood pressure levels were significantly lower than preoperative values. GH positive SPAs may affect the homeostasis of blood pressure.

Immune checkpoint inhibitors, such as ipilimumab and nivolumab, reverse the imbalance of antitumor self-tolerance and enhance T-cell responses. Currently, ipilimumab and nivolumab have a reported therapeutic impact on unresectable or metastatic melanomas; however, they also induce immune-related adverse events (irAEs). Ipilimumab-induced cutaneous irAEs are mostly low grade and manageable, although all-grade rash may occur in approximately 45% of all patients. We here report the case of a young woman with erythema multiforme major, which developed after sequential use of these 2 immune checkpoint inhibitors for advanced melanoma of the scalp. Initially, she received 12 cycles of nivolumab monotherapy followed by ipilimumab. A week later, multiple erythematous papulo-erythemas appeared on almost her entire body, with high-grade fever, mucosal involvements, and dyspnea. Immunohistochemistry using the lesioned skin revealed lymphocytic infiltration predominantly positive for CD8, contrasting with those for CD4 and Foxp3. Ipilimumab was stopped but she continued to receive empirical antibiotics; additionally, she was treated with intravenous steroid pulse therapy and immunoglobulin, followed by oral prednisolone. Her symptoms subsided rapidly, allowing a restart of nivolumab monotherapy alone. In our case, the long-standing preceding nivolumab monotherapy may synergistically and/or complementary have contributed to - in combination with the later administration of ipilimumab - recover antigen-responsive T-cell immunity, which is similar to the concept of immune reconstitution inflammatory syndrome, resulting in the establishment of an underlying immunopathology of erythema multiforme and life-threatening airway obstruction.

We surveyed the actual conditions of mammography with regard to image quality and radiation dose at 44 facilities in Kagoshima prefecture in 1999. In April 2004, guidelines for mammography newly included the standard of digital mammography. From September to October 2005, the survey was conducted at 48 facilities, and the results of the survey were compared with that in 1999. We visited 44 of the 48 facilities, and visually evaluated the image quality of mammograms for RMI156 and clinical mammograms. In addition, we measured average mammary gland dose at each facility. The number of the mammography device that satisfied the specified guideline criterion was larger than that in 1999. Image quality for the RMI156 mammograms improved. However, the results of the present survey revealed several problems. First, the number of facilities that had quality control instruments for mammography are few. Second, radiological technologists, medical doctors, and nurses did not share knowledge or information regarding mammography. Finally, there were differences in devices and image quality for mammography among the facilities. We achieved an understanding of the actual conditions of mammography in Kagoshima prefecture by visiting many facilities, evaluating image quality, and communicating with many staff members. Our results may be useful for the development of mammography examinations.
