We herein present the case of a 55-year-old woman with a previous history of malignancies--uterine adenocarcinoma, basal cell carcinoma (which occurred twice consecutively), recurrent respiratory infections due to common variable immunodeficiency (CVID), and systemic granulomatous disease diagnosed at a later age. The patient suffered from diffuse large B cell lymphoma (DLBCL), which was successfully treated with R-CHOP chemotherapy, and continued with immunoglobulin supplementation. The patient was free of lymphoma and infectious complications for over 20 months despite her persistent immunodeficiency, but eventually developed colorectal adenocarcinoma. To the best of our knowledge, this is the first reported case of CVID associated with multiple solid tumours and DLBCL.

Portal annular pancreas is one of the pancreatic fusion anomalies in which the uncinate process of the pancreas extends to fuse with the dorsal pancreas by encircling the portal vein or superior mesenteric vein. We report two consecutive patients with portal annular pancreas. The first case is a 71-year-old male patient who underwent a pancreaticoduodenectomy for intraductal papillary mucinous neoplasm in the head of pancreas. His preoperative computed tomography scan showed the suprasplenic type portal annular pancreas. The second case is a 74-year-old female patient who underwent a laparoscopic anterior radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic body cancer. In operative finding, portal confluence (superior mesenteric vein-splenic vein-portal vein) was encased with the uncinate process of pancreas in both cases. Therefore, they required pancreatic division at the pancreatic neck portion twice. During the postoperative period, grade B and A, respectively, postoperative pancreatic fistulas occurred and were controlled by conservative management. Surgeons need to know about this rare pancreatic condition prior to surgical intervention to avoid complications, and to provide patients with well-designed, case-specific pancreatic surgery.

A small set of gastric adenocarcinomas (9%) harbor Epstein-Barr virus (EBV) DNA within malignant cells, and the virus is not an innocent bystander but rather is intimately linked to pathogenesis and tumor maintenance. Evidence comes from unique genomic features of host DNA, mRNA, microRNA and CpG methylation profiles as revealed by recent comprehensive genomic analysis by The Cancer Genome Atlas Network. Their data show that gastric cancer is not one disease but rather comprises four major classes: EBV-positive, microsatellite instability (MSI), genomically stable and chromosome instability. The EBV-positive class has even more marked CpG methylation than does the MSI class, and viral cancers have a unique pattern of methylation linked to the downregulation of CDKN2A (p16) but not MLH1. EBV-positive cancers often have mutated PIK3CA and ARID1A and an amplified 9p24.1 locus linked to overexpression of JAK2, CD274 (PD-L1) and PDCD1LG2 (PD-L2). Multiple noncoding viral RNAs are highly expressed. Patients who fail standard therapy may qualify for enrollment in clinical trials targeting cancer-related human gene pathways or promoting destruction of infected cells through lytic induction of EBV genes. Genomic tests such as the GastroGenus Gastric Cancer Classifier are available to identify actionable variants in formalin-fixed cancer tissue of affected patients.

Due to the advanced diagnostic technique and better understanding for multiple primary lung cancers (MPLC), the increasing incidence of MPLC has been reported. Very often, MPLC are misdiagnosed as metastasis because of lacking efficient molecular biomarkers for prediction and diagnosis. Studies on the molecular mechanism for tumorgenesis and progression of MPLC may therefore facilitate the discovery of biomarkers for disease diagnosis and prognosis, so that an individual and rational treatment can be achieved. We tried to further our understanding and improve the diagnostic skill for MPLC by reviewing the current status and the latest advancement of molecular markers related to MPLC.

Gastric cancer patients with severe liver dysfunction secondary to hepatic metastases have limited treatment options. Most cytotoxic drugs have a narrow therapeutic index. Although both capecitabine and oxaliplatin have been well tolerated as single agents for patients with severe hepatic dysfunction, the combination of these drugs has not been investigated. We report here on a case of successful treatment of a patient suffering with severe liver dysfunction and metastatic gastric cancer; the patient was treated with a combination of capecitabine and oxaliplatin (XELOX). The initial bilirubin level of the patient was 10.9 mg/dL. After two cycles of treatment, his bilirubin level decreased to 2.1 mg/dL. He has experienced an excellent radiological response and he has received six cycles of XELOX chemotherapy. XELOX chemotherapy is feasible and it can be associated with positive outcomes for the patients suffering with metastatic gastric cancer and severe liver dysfunction.
