Purpose: In the present study, we aimed to evaluate the efficacy and safety of camrelizumab combined with oxaliplatin plus S-1 in patients with resectable gastric or gastroesophageal junction cancer.

Methods: In this single-arm, phase II clinical trial, patients with locally advanced gastric or gastroesophageal junction adenocarcinoma were enrolled to receive three cycles of neoadjuvant camrelizumab and oxaliplatin plus S-1 every 3 weeks, followed by surgical resection and adjuvant therapy with the same regimen. The primary endpoint was pathological complete response (pCR) (ypT0) rate and secondary endpoints were R0 resection rate, total pCR (tpCR, ypT0N0) rate, major pathological response (MPR) rate, downstaging, objective response rate (ORR), disease control rate (DCR), event-free survival (EFS), overall survival (OS), and safety.

Background: The controversy surrounding Roux-en-Y (R-Y) and Billroth II with Braun (BII + B) reconstruction as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL.

Article Synopsis
  • A study compared two surgical techniques (modified overlap anastomosis vs. conventional incision-assisted anastomosis) for laparoscopic total gastrectomy in gastric cancer patients at a hospital from 2016 to 2020.
  • The modified overlap group experienced less postoperative pain, quicker recovery milestones, and a shorter hospital stay, with no increased risk of complications compared to the conventional group.
  • Patient quality of life scores indicated fewer issues with swallowing and eating after three years in the modified overlap group, with no recurrences of cancer observed in this group.

Article Synopsis
  • Invasive urothelial carcinoma (UC) with squamous and glandular differentiation is a severe cancer type, with standard treatment being radical cystectomy, which can greatly affect patients' quality of life, leading to a growing interest in bladder-sparing therapies.
  • A case study of a 60-year-old male diagnosed with muscle-invasive bladder cancer (cT3N1M0) showed positive PD-L1 expression, and he underwent a transurethral resection followed by a combination of chemotherapy (cisplatin/gemcitabine) and immunotherapy (tislelizumab).
  • After 2 and 4 cycles of treatment, the patient demonstrated no tumor recurrence and achieved bladder preservation, remaining tumor-free for over

Background: Giant renal angiomyolipomas (AMLs) may lead to complications including flank pain, hematuria, hypertension, retroperitoneal hemorrhage and even death. Giant AMLs which grow around renal hilar vessels and the ureter are rare. Most previous reports on the treatment of giant renal AMLs have focused on open surgery or a transperitoneal approach, with few studies on the retroperitoneal approach for large AMLs.

In this experiment, Genetically improved farmed Nile tilapia Oreochromis niloticus were intraperitoneally injected with 1 g glucose/kg of body weight or saline. Red and white muscle tissues were collected at 0, 1, 2, 4, 6 and 12 h after the glucose tolerance test (GTT) or saline injection, and the time course of changes in molecular and metabolic adaption of glucose metabolism of these two tissues were evaluated. The results showed that the expression of insulin-responsive glucose transporter 4 (glut4) was up-regulated at 4 h after the GTT in the red muscle, implying an increase of glucose uptake.

Protein kinase C epsilon (PKCε), a member of the novel PKC family, is known to be a transforming oncogene and tumor biomarker for many human solid cancers including renal cell carcinoma (RCC). We isolated side population (SP) cells from the RCC 769P cell line, and proved that those cells possess cancer stem cell (CSC) characteristics. In this study, to identify the function of PKCε in cancer stemness of 769P SP cells, we reduced the expression of PKCε in those cells, following the results demonstrated that PKCε depletion had a negative correlation with the existence of SP cells in 769P cell line.

Background: Bladder cancer is the most common malignancy in urinary system and the ninth most common malignancy in the world. MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression by targeted repression of transcription and translation and play essential roles during cancer development. We investigated the expression of miR-135a in bladder cancer and explored its bio-function during bladder cancer progression.

Although cancers are widely considered to be maintained by stem cells, the existence of stem cells in renal cell carcinoma (RCC) has seldom been reported, in part due to the lack of unique surface markers. We here identified cancer stem cell-like cells with side population (SP) phenotype in five human RCC cell lines. Flow cytometry analysis revealed that 769P, a human clear cell RCC cell line, contained the largest amount of SP cells as compared with other four cell lines.

Objectives: To analyze the perioperative complications of radical cystectomy using a standardized reporting methodology.

Methods: The clinical data of 233 cases of radical cystectomy from January 1996 to December 2008 were reviewed. Two hundred male patients and 33 female patients were included.

Background: Multiple recurrences are common in non-muscle invasive bladder cancer, but the risk of multiple recurrences has not been fully described. Identifying patients at high risk of multiple recurrences will help to select an optimal therapeutic strategy and to improve prognosis. This study was conducted to identify the risk factors for multiple recurrences of non-muscle invasive bladder cancer.

Purpose: To assess efficacy of Ki67 combined with VEGF as a molecular grading model to predict outcomes with non-muscle invasive bladder cancer (NMIBC).

Materials: 72 NMIBC patients who underwent transurethral resection (TUR) followed by routine intravesical instillations were retrospectively analyzed in this study. Univariate and multivariate analyses were performed to confirm the prognostic values of the Ki67 labeling index (LI) and VEGF scoring for tumor recurrence and progression.

Mitochondrial tumor suppressor 1 (MTUS1) is a newly identified candidate tumor suppressor gene. Previous studies have demonstrated that the expression status of MTUS1 is altered in several types of tumors. However, its clinical significance for bladder cancer patients remains undetermined.

In order to obtain a full-length expression plasmid for human PDLIM2 gene, fragment amplification was used to clone its full-length coding sequence (CDS) region. The amplified PCR product was then digested and inserted into the pMD 18-T vector and subcloned into the pIRES2-EGFP plasmid to form the pIRES2-EGFP-PDLIM2 eukaryotic expression vector. After it was transfected to the bladder cancer cell line, BIU-87, the biological activities of high expression were verified by RT-PCR and Western blotting.
