BACKGROUND: The first-line treatment for resectable pancreatic cancer (RPC) is surgical resection. However, our patients have often experienced early recurrence after curative resection for RPC, with desperately poor prognosis. Some reports indicated that minimally distant metastasis not detected at operation might cause early recurrence. The present study aimed to identify preoperative clinicopathological features of early recurrence after curative resection of RPC. METHODS: Ninety RPC patients who underwent curative resection between 2000 and 2014 at our institution were retrospectively analyzed...

The pretargeting system based on the inverse electron demand Diels-Alder reaction (IEDDA) between trans-cyclooctene (TCO) and tetrazine (Tz) combines the favorable pharmacokinetic properties of radiolabeled small molecules with the affinity and specificity of antibodies. This strategy has proven to be an efficient method for the molecularly targeted delivery of pharmaceuticals, including isotopes for radiological imaging. Despite encouraging results from in vivo PET imaging studies, this promising system has yet to be thoroughly evaluated for pretargeted radioimmunotherapy (PRIT)...

BACKGROUND: Colorectal cancer (CRC) is one of the leading cause of cancer deaths worldwide. Since CRC is largely asymptomatic until alarm features develop to advanced stages, the implementation of the screening programme is very much essential to reduce cancer incidence and mortality rates. CRC occurs predominantly from accumulation of genetic and epigenetic changes in colon epithelial cells, which later gets transformed into adenocarcinomas. SCOPE OF REVIEW: The current challenges of screening paradigm and diagnostic ranges are from semi-invasive methods like colonoscopy to non-invasive stool-based test, have resulted in over-diagnosis and over-treatment of CRC...

To determine the level of cell-free DNA (cfDNA), Septin 9 (SEPT9) and tumor markers (CEA, AFP, CA19-9, TPA, CA72-4). Plasma samples were collected four times a day (06:00, 12:00, 18:00, 24:00) from 9 patients with CRC (5 stage I-II, 4 stage III-IV), from one with colorectal adenoma and from one healthy control. CfDNA was isolated, quantified and bisulfite-converted. CfDNA and methylated SEPT9 were determined by RT-PCR. Plasma levels of conventional tumor markers were also measured. The lowest cfDNA concentrations were observed at 24:00 and 18:00 in stage I-III patients...

BACKGROUND: Amyloidosis is particularly difficult to diagnose because the signs and symptoms are subtle. Additionally, there are no specific imaging or laboratory tests, except histopathology. Although it is considered to be a systemic disorder, a small portion of cases may be localized. INTRODUCTION OF THE CASE: A 54-year-old man presented with nonspecific symptoms (jaundice and back pruritus). Biochemical tests showed a high level of bilirubin and elevated serum tumor markers (CA19-9 and CA125)...

AIM: Liver cysts are the most common extrarenal manifestation in patients with autosomal dominant polycystic kidney disease (ADPKD). Carbohydrate antigen 19-9 (CA19-9) is generally used as a marker for biliopancreatic malignancies, although CA19-9 levels in patients with ADPKD are largely unknown. METHODS: A prospective observational study of 53 ADPKD patients and 83 non-ADPKD control subjects was performed. The serum levels of CA19-9 were studied to evaluate the association with clinical parameters and liver cysts...

Background. Malignant neoplasms arising in Meckel's diverticulum, a vitelline duct remnant, are rare yet well-documented. Case Presentation. A 53-year-old previously healthy female presented with an enlarging midline abdominal wall mass. A computed tomography scan revealed a mass involving the linea alba, bilateral rectus abdominis, and subcutaneous fat. Extensive clinical workup failed to demonstrate other lesions, except local and paratracheal/hilar lymphadenopathy. Histopathologic examination of the resected tumor demonstrated a spectrum of serous neoplasia including serous cystadenoma, papillary serous carcinoma with numerous Psammoma bodies, and a poorly differentiated component...
