Although elevated CD4⁺Foxp3⁺ regulatory T cell (Treg) frequencies within tumors are well documented, the functional and phenotypic characteristics of CD4⁺Foxp3⁻ subsets from matched blood, healthy colon, colorectal cancer require in-depth investigation. Flow cytometry revealed that majority intratumoral cells (Tregs) were Helios⁺ expressed higher levels cytotoxic T-lymphocyte antigen 4 (CTLA-4) CD39 than Tregs colon blood. Moreover, ∼30% markers associated with functions, including...

Survival and relapse after gastric cancer surgery are largely attributed to tumor biology surgical radicality; yet, other prognostic factors have been reported, including respiratory sepsis anastomotic leakage, but not global morbidity severity score (MSS). The hypothesis tested was that MSS would be associated with both disease-free (DFS) overall survival (OS).

Abstract Background Inflammation has an important role in cancer survival, yet whether serum markers of inflammation predict response to potentially curative neoadjuvant chemotherapy (NAC) oesophageal adenocarcinoma (OAC) is controversial. This study aimed determine the systemic inflammatory (SIR) associated with NAC and survival.

The relationship between the adaptive CD4+ T cell response and human cancer is unclear. oncofetal antigen 5T4 expressed on many carcinomas, including colorectal (CRC) cells, but has limited expression normal tissues. We previously identified anti-5T4 cells in a proportion of CRC patients, we extended this study to examine whether quality or quantity reflects tumor stage. An overlapping peptide library spanning was used as target enumerate cognate IFN-γ+CD4+ T-cells (measured spot forming...

Lymphoepithelial cyst of the pancreas is a rare benign lesion that should be managed conservatively. Similarity has been described between lymphoepithelial and branchial neck.We report 58-year-old man presenting with left sided abdominal pain initially thought to renal colic. CT abdomen revealed 3.5 cm in pancreatic tail. A laparoscopic distal pancreatectomy was planned for definitive treatment; however, endoscopic ultrasound guided fine needle aspiration (EUS-FNA) performed prior surgery as...

The oncofoetal antigen 5T4 is a promising T cell target in the context of colorectal cancer, as demonstrated by recent clinical study where 5T4-specific responses, induced vaccination or cyclophosphamide, were associated with significantly prolonged survival patients metastatic disease. Whilst Th1-type (IFN-γ+) responses specific to 5T4, and other antigens, are often readily detectable early stage CRC healthy donors, their activity suppressed cancer progresses CD4+CD25hiFoxp3+ regulatory...

Abstract Small intestine neuroendocrine tumours (SI‐NETs) are often diagnosed late with a UK median of 3 years and high misdiagnosis rates. Previous studies, largely based on patient surveys, offer little data improving diagnosis. In 2017, the South Wales NET service underwent nationally commissioned, systematic transformation, aiming to improve diagnosis through development gastroenterology surgical referral network, education these specialities. This study aims assess impact transformation...
