Intraoperative Radiotherapy With the Intrabeam® Device for the Treatment of Resectable Pancreatic Adenocarcinoma

ConclusionsThe application of radiotherapy with the Intrabeam® device in selected patients has not resulted in increased perioperative morbidity or mortality; therefore, this is a safe procedure for the treatment of resectable cancer.ResumenIntroducciónLa aplicación de radioterapia intraoperatoria en el lecho tumoral tras la resección de un cáncer de páncreas ha demostrado ser beneficiosa en el control local de la enfermedad. El objetivo de este estudio fue valorar los resultados iniciales obtenidos tras la aplicación de una nueva modalidad de radioterapia intraoperatoria (Intrabeam®) en términos de viabilidad, seguridad y resultados a corto plazo.MétodosSe estudiaron 5 pacientes sometidos a duodenopancreatectomía cefálica por cáncer de páncreas resecable, en los que se aplicó intraoperatoriamente un boost de radioterapia (5 Gy) en el lecho tumoral mediante la utilización del dispositivo portátil Intrabeam®, fuente puntual de rayos X de baja energía. Se analizaron las complicaciones, estancia y mortalidad postoperatorias, recidivas y superviviencia a corto plazo.ResultadosLa edad media fue de 68 años. Todos los pacientes presentaban un estadio tumoral T3 y uno de ellos N1. En 3 pacientes se realizó una resección R0 y en 2 casos resultó ser una resección R1. La mortalidad peroperatoria fue del 0%. Solo se presentaro...

It is of interest because of a possible prognostic role of differential expression in tumors and its role as a target for indatuximab, a monoclonal antibody coupled with a cytotoxic agent. To comprehensively analyze ...

Abstract CD28H and B7-H5 have been identified as receptor-ligand pairs in B7/CD28 family, and have costimulatory activity in immune cells. Here, we have systematically reviewed the research reports on the CD28H/B7-H5 pathway. It was found that CD28H is mainly expressed in T cells and natural killer (NK) cells with naive and poorly differentiated properties, and repeated antigen stimulation leads to permanent loss of CD28H. In tumors, CD28H is mainly expressed in tissue-resident memory (TRM ) lymphocyte T cells, which is associated with improved tumor prognosis. B7-H5 is a ligand for CD28H and is widely expressed i...

AbstractThe clinical application of photodynamic therapy (PDT) for gastrointestinal (GI) neoplastic lesions has been developed with appreciation for the great efforts and kind support of Dr. Tom Dougherty and his followers ’ contributions. There are several published studies on clinical PDT in the field of GI oncology. Esophageal cancer was one of the first clinical indications for PDT that was approved as an endoscopic procedure in both the United States and Japan. PDT was initially used as a palliative local treat ment for patients with obstructive esophageal cancer. PDT is also indicated for eradicative therapy fo...

The SOX2OT gene is comprised of 10 exons and more than two transcription start sites. Dysregulation of SOX2OT is observed in various tumors, including lung cancer, gastric cancer, esophageal cancer, breast cancer, hepatocellular carcinoma, ovarian cancer, pancreatic ductal adenocarcinoma, laryngeal squamous cell carcinoma, cholangiocarcinoma, osteosarcoma, nasopharyngeal carc...

AbstractThe Japanese guideline for gastroenteropancreatic neuroendocrine tumor treatment recommends everolimus or sunitinib as first-line treatment for unresectable pancreatic neuroendocrine tumors (PNETs). Streptozocin (STZ) is recommended as an alternative. We encountered a patient with PNET who had multiple liver metastases and who showed a remarkable response to third-line STZ. The patient was a 50-year-old man with a pancreatic head tumor 32  mm in diameter. We planned to perform subtotal stomach-preserving pancreaticoduodenectomy, but abandoned resecting the pancreas during the surgery upon discovering a small l...

Rationale: Total pancreatectomy (TP) is performed in cases of multifocal and large invasive tumors of the pancreas, and is associated with high rates of mortality and morbidity. Previously, the limitations and unsatisfactory effect of this surgery rendered it rarely performed; however, with improvements in surgical techniques and blood sugar management, TP is now more frequently performed. TP has a similar long-term survival rate as that for pancreatoduodenectomy (PD). However, the application of TP plus total gastrectomy (TG) for the treatment of invasive pancreatic ductal adenocarcinoma has not been reported previously...

Abstract In their seminal papers Hanahan and Weinberg described oncogenic processes a normal cell undergoes to be transformed into a cancer cell. The functions of ion channels in the gastrointestinal (GI) tract influence a variety of cellular processes, many of which overlap with these hallmarks of cancer. In this review we focus on the roles of the calcium (Ca2+), sodium (Na+), potassium (K+), chloride (Cl-) and zinc (Zn2+) transporters in GI cancer, with a special emphasis on the roles of the KCNQ1 K+ channel and CFTR Cl- channel in colorectal cancer (CRC). Ca2+ is a ubiquitous second messenger, serving as a sig...
