The prognostic significance of pelvic and para-aortic lymphadenectomy during primary debulking surgery for advanced-stage ovarian cancer remains unclear. This study aimed to evaluate the survival impact of lymph node dissection (LND) in patients treated with optimal cytoreduction for advanced ovarian cancer. Data from 158 consecutive patients with stage IIIC-IV disease who underwent optimal cytoreduction (<1 cm) were obtained via retrospective chart review. Patients were classified into two groups: (1) lymph node sampling (LNS), node count <20; and (2) LND, node count ≥20...

Several studies have demonstrated that YWHAZ (14-3-3ζ), included in the 14-3-3 family of proteins, is implicated in the initiation and progression of cancers. To detect a novel treatment target for adenocarcinoma of the esophagogastric junction (AEG), we tested whether YWHAZ acted as a cancer-promoting gene through its overexpression in AEG. We analyzed YWHAZ protein expression in 92 consecutive primary AEG tumors, which had been curatively resected in our institution between 2000 and 2010. Overexpression of the YWHAZ protein was frequently detected in primary AEG tumor samples (46% (42/92))...

Non-small cell lung cancer (NSCLC) is one of the leading causes of cancer-associated mortality globally. Interactions of the cancer cells with the tumor microenvironment are essential carcinogenic features for the majority of solid tumors, such as pancreatic cancer. The present study investigated the role of stromal activation in NSCLC and analyzed the surgical specimens of 93 patients by immunohistochemistry with regard to periostin (an extracellular matrix protein), α-smooth muscle actin (α-SMA; a marker of myofibroblasts) and cluster of differentiation 31 (CD31; a marker of endothelial cells), and the activated stroma index...

The prognostic value of programmed death-ligand 1 (PD-L1) in gastric cancer (GC) remains controversial. To clarify this problem, we performed a meta-analysis of research studies identified in the PubMed, EMBASE and the Cochrane Library databases. A total of 1,901 patients in 10 studies were enrolled in this meta-analysis, and the pooled hazard ratio (HR) of 1.64 (95% CI 1.11 to 2.43; P = 0.01) indicated that PD-L1 expression is associated with a shorter overall survival (OS). The pooled odds ratios (ORs) indicated that PD-L1 expression was associated with tumour size (OR = 1...

PURPOSE: The prostate-specific membrane antigen (PSMA) targeted positron-emitting-tomography (PET) tracer (68)Ga-PSMA-11 shows great promise in the detection of prostate cancer. However, (68)Ga has several shortcomings as a radiolabel including short half-life and non-ideal energies, and this has motivated consideration of (18)F-labelled analogs. (18)F-PSMA-1007 was selected among several (18)F-PSMA-ligand candidate compounds because it demonstrated high labelling yields, outstanding tumor uptake and fast, non-urinary background clearance...
