Spontaneous high clonal expansion of Wilms' tumor gene 1-specific cytotoxic T-lymphocytes in patients with Wilms' tumor gene 1-expressing solid tumor.

Wilms' tumor protein 1 (WT1)-targeted immunotherapy has been used in patients with leukemia and solid tumors. However, the spontaneous WT1-specific immune response before WT1 peptide vaccination in patients with WT1-expressing tumors (PTs) remains unclear. Therefore, we investigated whether WT1-specific cytotoxic CD8 T-lymphocytes (CTLs) are clonally expanded in the peripheral blood outside of tumor sites.

Questionnaire to Survey Cosmetic Outcomes in Laparoscopic Surgery for Colorectal Cancer.

Background And Objectives: There has been a steady increase in the use of minimally invasive surgery, including conventional multiport laparoscopic surgery (MLS) and single-site laparoscopic surgery (SLS) for colorectal cancer. We aimed to evaluate how important the cosmetic outcome, one of the advantages of SLS, is to patients and whether SLS reflects social needs.

Methods: We used a web-based questionnaire to survey nonmedical and medical workers for what factors were considered on the assumption that respondents undergo colorectal cancer surgery and that the most important person for them undergoes.

Prognostic impact of combination therapy with gemcitabine and cisplatin plus S-1 and subsequent conversion surgery for initially unresectable upper biliary tract cancers.

Purpose And Background: For the past decade, there have been few chemotherapy options for unresectable biliary tract cancer (BTC). Recently, however, combination therapy with gemcitabine and cisplatin plus S-1 (GCS) has been identified as a promising strategy. This retrospective study analyzes the clinical results of GCS therapy and subsequent conversion surgery (CS).

Evaluation of the measurement accuracy and uncertainty of a solid-state detector under diagnostic x-ray beam conditions.

Objective: An accurate measurement of x-ray beams is expected to reduce the uncertainties associated with estimating radiation risk to patients in clinical settings. To perform assessment tasks based on the readings of a solid-state detector (SSD) using semiconductor technology, the characteristics of the detector should be elucidated. In this study, we evaluated the measurement accuracy of a new SSD under diagnostic x-ray beam conditions in terms of air kerma, tube voltage, and half-value layer (HVL).

Practical use of transanal decompression tube following the repair of fourth-degree perineal tears associated with vaginal delivery.

Background: Fourth-degree perineal tears associated with vaginal delivery (PTAVD) occur in approximately 0.25 to 6% of vaginal deliveries. A persistent challenge in treating fourth-degree PTAVD is the high incidence of anastomotic leakage, leading to impaired quality of life, marked by incontinence, rectovaginal fistula, and painful sexual intercourse.

Giant hemorrhagic pancreatic pseudocyst with suspected cystic pancreatic tumor: a case report.

Pancreatic pseudocysts are surrounded by a non-epithelialized wall confined to the pancreas and localized to the pancreatic tissue or adjacent pancreatic cavity. In contrast, pancreatic cystic tumors occur less frequently than solid lesions and are often detected incidentally on imaging. Regarding the qualitative diagnosis of pancreatic pseudocysts, it is important to differentiate them from neoplastic cysts.

[A Study on the Uncertainty of the Average Glandular Dose in Quality Control of Mammographic X-ray Units].

【Purpose】 Accurate control of X-ray units and dosimeters and analysis of the uncertainties associated with the accurate measurement of radiation doses are essential for the effective establishment and application of diagnostic reference levels. In this study, the uncertainty of the average glandular dose (AGD) in the quality control of mammography equipment was evaluated in detail, and recommendations were provided to improve the accuracy and safety of radiological practice. 【Methods】 In the uncertainty analysis of the AGD, the relative standard uncertainties in the measurements of the half-value layer, the incident air kerma, and the conversion factor were considered and finally expressed as expanded uncertainties, the intervals of which were clearly defined.

Hepatoprotective effects of baicalein against liver ischemia-reperfusion injury and partial hepatectomy in a rat model.

Background: Baicalein is the main active flavonoid in Scutellariae Radix and is included in shosaikoto, a Kampo formula used for treating hepatitis and jaundice. However, little is known about its hepatoprotective effects against hepatic ischemia-reperfusion injury (HIRI), a severe clinical condition directly caused by interventional procedures. We aimed to investigate the hepatoprotective effects of baicalein against HIRI and partial hepatectomy (HIRI + PH) and its potential underlying mechanisms.

Appendiceal Metastasis of Breast Cancer: A Case Report and a Literature Review.

Appendiceal metastases of breast cancer (BC) are very rare, and there are few reports of resection. Asymptomatic appendiceal enlargement is often suspected to be a primary appendiceal tumor, making it difficult to suspect metastatic tumors, especially metastases from BC. On the other hand, advances in drug therapy, including hormonal therapy for BC, have prolonged survival, and there is a possibility of encountering metastatic cases that have rarely been seen before.

[A Case of Adenocarcinoma of Duct of Luschka].

A 75-year-old man was transferred to our hospital with a diagnosis of acute cholecystitis. On next day, a laparoscopic cholecystectomy was performed. Histologic examination confirmed an adenocarcinoma arising from duct of Luschka.

[A Case of Unresectable Advanced Lower Esophageal Adenocarcinoma That Achieved Pathological Complete Response after Conversion Surgery following Nivolumab plus SOX Therapy].

An 80-year-old woman presented with epigastric discomfort and dysphagia, underwent upper gastrointestinal endoscopy, and was diagnosed with type 2 advanced lower esophageal adenocarcinoma. Computed tomography data revealed that there was the lower esophageal tumor is T3, but a large carina lymph node invading the left bronchus. We diagnosed this patient unresectable cT4bN1M0, cStage ⅣA advanced esophageal adenocarcinoma, and we administered nivolumab plus S-1 plus oxaliplatin(SOX)therapy.

Hepatoprotection of a Standardized Extract of Cultured Mycelia against Liver Injury Induced by Ischemia-Reperfusion and Partial Hepatectomy.

A standardized extract of cultured mycelia (ECLM, AHCC) has been shown to have beneficial effects on organ metabolism. ECLM has been indicated to have liver protective properties by suppressing inflammatory responses. The pathogenesis of hepatic ischemia-reperfusion injury is thought to involve the induction of inflammatory mediators.

Sulforaphane Is Protective against Warm Ischemia/Reperfusion Injury and Partial Hepatectomy in Rats.

Sulforaphane (SFN) has various beneficial effects on organ metabolism. However, whether SFN affects inflammatory mediators induced by warm hepatic ischemia/reperfusion injury (HIRI) is unclear. To investigate the hepatoprotective effects of SFN using an in vivo model of HIRI and partial hepatectomy (HIRI + PH), rats were subjected to 15 min of hepatic ischemia with blood inflow occlusion, followed by 70% hepatectomy and release of the inflow occlusion.
