The patient is a 15-year-old female who initially presented to our hospital at the age of 6 with complaints of tachycardia. However, no significant abnormalities were identified, and she was subsequently placed under observation. At the age of 7, the patient developed symptoms including headache, chest pain, and absent pulses, accompanied by a pronounced inflammatory response. A thorough diagnostic evaluation was performed, which led to the diagnosis of Takayasu’s arteritis. At that time, computed tomography (CT) imaging revealed a fusiform aortic aneurysm with a maximum short axis diameter of 34 mm, extending from the ascending aorta to the proximal aortic arch. Under vigilant monitoring, by the age of 15, the maximum short diameter had increased to 45 mm, demonstrating progressive enlargement over time. Following a multidisciplinary discussion of treatment options in a heart team conference, it was determined that surgical intervention was warranted. Given that the patient was receiving maintenance therapy for a relapse of arteritis, the dose of prednisolone was reduced to 4 mg prior to performing an ascending partial arch aortic replacement. The postoperative course was uneventful, and the patient was discharged on postoperative day 13. She continues to receive maintenance therapy and undergoes regular CT scans at the outpatient clinic. Childhood-onset Takayasu’s arteritis is exceedingly rare, but with timely surgical intervention and sustained disease management, an improved long-term prognosis can be anticipated.

Objective: The prognostic value and clinical usage of peritoneal cytology in endometrial cancer are uncertain. This study aimed to determine whether positive cytology is associated with the prognosis for endometrial cancer. Methods: A Japanese nationwide retrospective registry study was conducted between 2012 and 2019. Clinicopathological data were analyzed for patients who were registered in the Japan Society of Obstetrics and Gynecology (JSOG) gynecological tumor registry and underwent initial treatment for endometrial cancer. Results: In total, 83,027 patients who met the inclusion criteria were identified. Data on peritoneal cytology status and overall survival (OS) were available for 74,984 and 36,995 patients, respectively. Positive peritoneal cytology was found in 11,536 (15.4%) patients. A higher proportion of patients who had positive peritoneal cytology were related to advanced stages, high-grade histology, deep myometrial invasion, lymph node (LN) metastasis, and poor risk of recurrence. After controlling for age, stage, myometrial invasion, LN metastasis, distant metastasis, and risk of recurrence, positive peritoneal cytology was associated with poor prognosis (p<0.001). Multivariate Cox regression analysis revealed that clinicopathological factors (i.e., age, International Federation of Gynecology and Obstetrics stage, histological type, myometrial invasion, LN metastasis, distant metastasis, and peritoneal cytology), including positive peritoneal cytology, were also significant prognostic factors for OS. Conclusion Positive peritoneal cytology was a prognostic factor for endometrial cancer for the JSOG gynecological tumor registry.

With increasing global life expectancy, the significance of geriatric assessment parameters has increased. Sarcopenia is a crucial assessment parameter and is defined as the age-related loss of muscle mass and strength. Sarcopenia is widely acknowledged as a risk factor for postoperative complications in diverse advanced malignancies and has a detrimental effect on the long-term prognosis. While most studies have primarily concentrated on the correlation between sarcopenia and advanced cancer, more recent investigations have focused on the relationship between sarcopenia and early-stage cancer. Endoscopic submucosal dissection (ESD), which is less invasive than surgical intervention, is extensively employed in the management of early-stage cancer, although it is associated with complications such as bleeding and perforation. In recent years, several reports have revealed the adverse consequences of sarcopenia in patients with early-stage cancer undergoing ESD. This literature review briefly summarizes the recent studies on the association between sarcopenia and ESD.

Objective: In this study, we collected data over 8 years (2012–2019) from the Japan Society of Obstetrics and Gynecology (JSOG) tumor registry to determine the status of endometrial cancer in Japan, and analyzed detailed clinicopathological factors. Methods: The JSOG maintains a tumor registry that gathers information on endometrial cancer treated at the JSOG-registered institutions. Data from the patients whose endometrial cancer treatment was initiated from 2012 to 2019 were analyzed retrospectively. Results: A total of 82,969 patients with endometrial cancer underwent treatment from 2012 to 2019. Chemotherapy alone or in combination with hormonal therapy is more common among endometrial cancer patients under 40 years compared with those over 40 years. The number of patients with endometrial cancer, treated with laparoscopic or robot-assisted surgery was observed to have increased yearly. Small cell carcinomas and undifferentiated carcinomas were more likely to be diagnosed at an advanced stage. Lymphadenectomy was most commonly performed for stage IIIC2 disease, whereas positive peritoneal washing cytology was most common for stage IVB and serous carcinoma. Conclusion Multi-year summary reports provided detailed clinicopathological information regarding endometrial cancer that could not be obtained in a single year. These reports were useful in understanding treatment strategies and trends over time based on age, histology, and stage.

Introduction: Since the commercial availability of buprenorphine extended-release transdermal patches (BTDP) from the early 2010’s, the therapeutic indications for opioids have widely expanded to include chronic benign diseases. We report a case of a home health care patient with acute opioid withdrawal symptoms due to self-interruption of BTDP. Case: An 84-year-old man using home health care services due to worsening of lumbar spinal canal stenosis had been receiving analgesia with a BTDP, a mixed opioid agonist/antagonist analgesic, for the preceding five months. Since the patient's spouse thought that his pain and symptoms were gradually improving, she secretly replaced the BTDP with an NSAID patch without informing the patient. About 50 hours later, the patient experienced a variety of symptoms, including frequent urination with incontinence every five minutes, watery diarrhea, sweating, decreased blood pressure, discomfort in the feet, and insomnia. Evaluation of the Clinical Opiate Withdrawal Score (COWS) by the home health care physician indicated a score of 12, corresponding to mild withdrawal symptoms. About 12 hours after symptom onset, the severe abnormalities were barely noticeable and completely disappeared after two days. Conclusion: Few previous case reports have described withdrawal symptoms due to rapid discontinuation of BTDP. In addition to the medical considerations, we report the social issues associated with onset of the condition in a home environment. Opioid use for non-cancer pain requires medication management from a different perspective than that for cancer pain.

Purpose: Gastric neoplasia is a common manifestation of familial adenomatous polyposis (FAP). This study aimed to elucidate the clinical characteristics, endoscopic features including fundic gland polyposis (FGPsis), and treatment outcomes of gastric neoplasms (GNs) in patients with FAP. Materials and Methods: A total of 35 patients diagnosed with FAP, including nine patients from four pedigrees who underwent esophagogastroduodenoscopy (EGD), were investigated regarding patient characteristics, GN morphology, and treatment outcomes. Results: Twenty-one patients (60.0%) had 38 GNs; 33 (86.8%) and 5 (13.2%) were histologically diagnosed with adenocarcinoma and adenoma, respectively. There were no specific patient characteristics related to GNs.Nodule-type GNs were more prevalent in patients with FGP than without (52.2% vs. 0.0%, P=0.002) in the upper body of the stomach. Conversely, depressed-type GNs were fewer in patients with FGPsis than in those without (13.0% vs. 73.3%, P<0.001). Slightly elevated-type GNs were observed in both groups (34.8% vs. 20.0%, P=0.538). Even within pedigrees, the background gastric mucosa and types of GNs varied. In total, 24 GNs were treated with endoscopic submucosal dissection (ESD) and eight with endoscopic mucosal resection (EMR). EMR was selected for GNs with FGPsis because of the technical difficulty of ESD, resulting in a lower en bloc resection rate (62.5% vs. 100%, P=0.014). Conclusions Our study indicates the necessity of routine EGD surveillance in patients diagnosed with FAP. Notably, the morphology and location of GNs differed between patients with and without FGPsis. Endoscopic treatment and outcomes require more attention in cases of FGPsis.

Objective: To assess the efficacy of the FIGO 2018 classification system for nodal-specific classifications for early-stage cervical cancer; specifically, to examine the impact of nodal metastasis on survival and the effect of postoperative treatments, according to histological subtypes. Methods: This society-based retrospective observational study in Japan examined 16,539 women with the 2009 FIGO stage IB1 cervical cancer who underwent primary surgical treatment from 2004 to 2015. Associations of cause-specific survival (CSS) with nodal metastasis and postoperative adjuvant therapy were examined according to histology type (squamous cell carcinoma [SCC], n=10,315; and non-SCC, n=6,224). Results: The nodal metastasis rate for SCC was higher than that for non-SCC (10.7% vs. 8.3%, p<0.001). In multivariable analysis, the impact of nodal metastasis on CSS was greater for non-SCC tumors (adjusted-hazard ratio [HR], 3.11; 95% confidence interval [CI], 2.40–4.02) than for SCC tumors (adjusted-HR, 2.20; 95% CI, 1.70–2.84; p<0.001). Propensity score matching analysis showed significantly lower CSS rates for women with pelvic nodal metastasis from non-SCC tumors than from SCC tumors (5-year CSS rate, 75.4% vs. 90.3%, p<0.001). The CSS rates for women with nodal metastasis in SCC histology were similar between the postoperative concurrent chemoradiotherapy/radiotherapy and chemotherapy groups (89.2% vs. 86.1%, p=0.42), whereas those in non-SCC histology who received postoperative chemotherapy improved the CSS (74.1% vs. 67.7%, p=0.043). Conclusion The node-specific staging system in the 2018 FIGO cervical cancer classification is applicable to both non-SCC tumors and SCC tumors; however, the prognostic significance of nodal metastases and efficacy of postoperative therapies vary according to histology.
