Area of Residual Tumor Measurement After Preoperative Chemotherapy as an Objective and Quantitative Method for Predicting the Prognosis of Gastric Cancer: A Single-Center Retrospective Study.

Background: Pathological regression grade after chemotherapy evaluated by surgically resected specimens is closely related with prognosis. Since usefulness of measuring the area of the residual tumor (ART) has been reported, this study aimed to evaluate the utility of ART in predicting the prognosis of patients with gastric cancer (GC) who received preoperative chemotherapy.

Methods: This single-center retrospective study examined the relationship between ART and survival outcomes.

The real-world efficacy and safety of frontline therapy of obinutuzumab plus bendamustine for untreated high-tumor-burden follicular lymphoma.

Background: While R-CHOP has been one of the standard therapies for untreated high-tumor-burden (HTB) follicular lymphoma (FL) for over 2 decades, obinutuzumab plus bendamustine (OB) is also currently regarded as the standard of care since its approval in 2018 in Japan; however, the long-term efficacy and safety of OB in the daily clinical practice has not been thoroughly evaluated.

Methods: We conducted a multicenter retrospective study for the clinical outcome of 53 patients with HTB FL treated by OB as the frontline therapy between 2018 and 2021 in the Kyoto Hematology Clinical Study Group (KOTOSG). All patients had at least 2-year follow-up period.

Successful Antibiotic Treatment of Phlegmonous Gastritis Following Allogeneic Hematopoietic Stem Cell Transplantation.

Phlegmonous gastritis (PG) is a rare, life-threatening bacterial infection characterized by thickening of the gastric wall. We report a case of PG in a 17-year-old male following allogeneic hematopoietic stem cell transplantation for severe aplastic anemia. Seven months after transplantation, the patient presented with severe abdominal pain, fever, and significant gastric wall thickening on CT.

Successful Kidney Transplantation for Bilateral Renal Hypoplasia With Ebstein Disease.

Background: Patients with renal hypoplasia are often associated with congenital heart disease (CHD). During the perioperative period of kidney transplantation (KTx), sufficient circulation volume is required to maintain renal blood flow in the donor kidney. However, little is known about the indication and management of KTx in patients with CHD who require precise hemodynamic assessment during transplantation.
