The associations between programmed cell death ligand 1 (PD-L1) and the prognosis of various cancers have always been a research topic of considerable interest. However, the prognostic value of PD-L1 in breast cancer patients remains a controversial subject. We aimed to assess the association between PD-L1 protein expression and clinicopathological features and the impact of this relationship on breast cancer survival. We performed a systematic search of the PubMed, EMBASE, and Cochrane Library databases to determine the correlations among PD-L1 expression, clinicopathological features and overall survival (OS)...

Immunohistochemistry of a transcription factor, GATA3, has been widely used as a promising urothelial marker in diagnostic surgical pathology practice. However, the expression status of GATA3 in upper urinary tract urothelial carcinomas (UUTUCs) and its prognostic significance have not been fully investigated. We immunohistochemically stained for GATA3 in 99 UUTUC samples and paired non-neoplastic urothelial tissues. GATA3 was positive in 51 [51.5%; 32 (32.3%) weak, 11 (11.1%) moderate, 8 (8.1%) strong] of 99 UUTUCs, which was significantly lower than in benign urothelium [79 (96...

BACKGROUND: Endoscopic resection (ER) is a widely accepted treatment for patients with early gastric cancer (EGC) with no lymph node metastasis. Occasionally, however, additional surgery is needed due to an incomplete resection. The purpose of this study was to detect clinical factors which might identify patients at greater risk of additional surgery after ER and to suggest an alternative treatment strategy for these patients. METHODS: This study retrospectively analyzed 350 patients with gastric cancer who underwent radical gastrectomy and lymphadenectomy after ER in a single institution between July 2004 and July 2014...

Previous studies demonstrated that several inflammation-based hematological indices are closely related to various malignancies, including colorectal cancer (CRC). In this study, the prognostic value of inflammation-based markers, including a combination index termed coNLR-PDW, comprising the preoperative neutrophil-to-lymphocyte ratio (NLR) and the platelet distribution width (PDW), was evaluated in 206 patients with non-metastatic CRC treated with surgery at a single medical center. The association of patient demographics, blood chemistry, and serum biochemical indices with recurrence-free survival (RFS) and overall survival (OS) were examined through univariate and multivariate analysis...

Importance: A pathologic complete response (pCR; no invasive or in situ cancer) occurs in 40% to 50% of patients with HER2-positive (HER2+) and triple-negative (TN) breast cancer. The need for surgery if percutaneous biopsy of the breast after neoadjuvant chemotherapy (NCT) indicates pCR in the breast (hereinafter referred to as breast pCR) has been questioned, and appropriate management of the axilla in such patients is unknown. Objective: To identify patients among exceptional responders to NCT with a low risk for axillary metastases when breast pCR is documented who may be eligible for an omission of surgery clinical trial design...

In this study, we aimed to explore whether low levels of mitochondrial DNA (mtDNA) content in the primary tumor could predict better outcome for breast cancer patients receiving anthracycline-based therapies. We hypothesized that tumor cells with low mtDNA content are more susceptible to mitochondrial damage induced by anthracyclines, and thus are more susceptible to anthracycline treatment.<br /><br />Experimental Design: We measured mtDNA content by a quantitative PCR approach in 295 primary breast tumor specimens originating from two well-defined cohorts: 174 lymph node-positive patients who received adjuvant chemotherapy and 121 patients with advanced disease who received chemotherapy as first-line palliative treatment...
