Histopathologic Comparison Among Drug Eruptions Induced by Enfortumab Vedotin, Brentuximab Vedotin, and Taxanes.

Microtubule-stabilizing agents (enfortumab vedotin and brentuximab vedotin) and microtubule-disrupting agents (docetaxel and paclitaxel) are used as anticancer agents but can also induce drug eruptions. Recently, mitotic arrest figures have been reported in various non-neoplastic cells as the histopathologic side effect of these drug eruptions. Therefore, we performed a comparative analysis of drug eruptions associated with these microtubule-targeting agents.

Fatal Spitz Melanoma With MAD1L1::BRAF Fusion: A Case Report and Literature Review.

Spitz melanoma is extremely rare, and only a few cases of distant metastases have been reported. Herein, we describe a case of Spitz melanoma with multiple distant metastases. A 37-year-old woman presented with a 5.

Updated review of perioperative treatment for non-small-cell lung cancer in the new era of immune checkpoint inhibitors: past, present, and future.

The perioperative treatments for non-small cell lung cancer (NSCLC) should control both local and microscopic systemic disease, because the survival of patients with NSCLC who underwent surgical resection alone has been dismal except in stage IA patients. One way to improve surgical outcome is the administration of chemotherapy before or after the surgical procedure. During the last two decades, many clinical studies have focused on developing optimal adjuvant or neoadjuvant cisplatin-based chemotherapy regimens that can be combined with surgical treatment and/or radiotherapy.

Relationship between Volpara Density Grade and Compressed Breast Thickness in Japanese Patients with Breast Cancer.

Background: High breast density found using mammographs (MGs) reduces positivity rates and is considered a risk factor for breast cancer. Research on the relationship between Volpara density grade (VDG) and compressed breast thickness (CBT) in the Japanese population is still lacking. Moreover, little attention has been paid to pseudo-dense breasts with CBT < 30 mm among high-density breasts.

Hidrocystoma-like tumours with RET or ALK fusion: a study of four cases.

Hidrocystoma is thought to be a benign retention cyst of sweat ductal units. The lesion is usually located in the periorbital skin; however, lesions with similar histopathological features are rarely observed in extra-facial sites. Herein, we present four cases of hidrocystoma-like tumours in extra-facial skin sites that harboured a RET or ALK rearrangement.

Primary Cutaneous NUT Carcinoma: Clinicopathologic and Genetic Study of 4 Cases.

WHO Classification of Skin Tumors, fifth edition (2023) has newly described primary cutaneous NUT carcinoma; however, information on this cancer type remains scarce. Herein, we performed clinicopathologic and genetic analyses of 4 cases. Four elderly women (median age 77 y, range: 68 to 82 y) were included.

Curative criteria for endoscopic treatment of oesophageal squamous cell cancer.

Endoscopic treatment of early oesophageal squamous cell carcinoma is widely accepted. ESD (Endoscopic Submucosal Dissection), which allows en bloc resection regardless of size, provides resected specimens that facilitate histological evaluation of curability. In the histological investigation, the determination of tumor depth, lymphovascular involvement, and lateral and vertical margins play a great role in the assessment of curability.

Recurrent GATA3 P409Afs*99 Frameshift Extension Mutations in Sweat-gland Carcinoma With Neuroendocrine Differentiation.

Sweat-gland carcinoma with neuroendocrine differentiation (SCAND) was recently proposed as a new cutaneous adnexal neoplasm with neuroendocrine differentiation; however, its genetics are not well known. Herein, we performed clinicopathologic and genetic analyses of 13 SCAND cases and 5 control cases of endocrine mucin-producing sweat gland carcinoma (EMPSGC). The SCAND group included 11 males and 2 females with a median age of 68 years (range, 50 to 80 y).

The clinical impacts of the prognostic nutritional index for the esophageal cancer patients who received curative treatment.

Background: We investigated the impact of the prognostic nutritional index (PNI) on esophageal cancer survival and recurrence after curative treatment.

Methods: This study included 120 patients who underwent curative surgery followed by the adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified.

A simpler diagnostic algorithm of the Japan Esophageal Society classification for Barrett's esophagus-related superficial neoplasia.

Background: We previously developed a Japan Esophageal Society Barrett's Esophagus (JES-BE) magnifying endoscopic classification for superficial BE-related neoplasms (BERN) and validated it in a nationwide multicenter study that followed a diagnostic flow chart based on mucosal and vascular patterns (MP, VP) with nine diagnostic criteria. Our present post hoc analysis aims to further simplify the diagnostic criteria for superficial BERN.

Methods: We used data from our previous study, including 10 reviewers' assessments for 156 images of high-magnifying narrow-band imaging (HM-NBI) (67 dysplastic and 89 non-dysplastic histology).

Patients Offer Radiofrequency Ablation Therapy for Early Breast Cancer as Local Therapy (PO-RAFAELO) Study under the Patient-proposed Health Services.

Introduction: Due to the increase in the number of early-stage breast cancer patients, there is growing interest in minimally invasive local therapies for breast cancer. Radiofrequency ablation (RFA) therapy is one of the most promising minimally invasive treatments. The Radiofrequency Ablation Therapy for Early Breast Cancer as Local Therapy (RAFAELO) study, a multicenter collaborative study that aims to validate the efficacy and safety of RFA and to standardize its use for early-stage breast cancer, was conducted under the Advanced Medical Care B system in 2013.

Apocrine carcinoma with marked sebocyte-like cytological features: A report of two cases.

Apocrine carcinoma cases with sebaceous differentiation have not been reported and can be misdiagnosed as sebaceous carcinoma. We present two cases of apocrine carcinoma with marked sebocyte-like cytological features. Tumors were observed in the left axilla of a 68-year-old man (Case 1) and the right axilla of a 72-year-old man (Case 2).

True diagnostic ability of EUS-guided fine-needle aspiration/biopsy sampling for small pancreatic lesions ≤10 mm and salvage diagnosis by pancreatic juice cytology: a multicenter study.

Background And Aims: The diagnostic performance of EUS-guided fine-needle aspiration/biopsy sampling (EUS-FNAB) for pancreatic ductal adenocarcinoma (PDAC) ≤10 mm in diameter is relatively low. Pancreatic juice cytology (PJC) has gained attention because of its high sensitivity for small PDACs. We aimed to clarify the diagnostic ability of EUS-FNAB and the salvage ability of PJC for PDAC ≤10 mm.

Psychological symptom burden associated with malignant wounds: Secondary analysis of a prospective cohort study.

Objectives: Patients with malignant wounds suffer from physical and psychological symptom burden. Despite psychological support being required, the impact of malignant wounds on patients' psychological distress is poorly investigated. We evaluated psychological distress associated with malignant wounds for patients at their end of life.
