BACKGROUND: Although it is well known that patients with malignant tumors have abnormal blood coagulation, its clinical significance has not been studied. We investigated the clinicopathological and prognostic impact of plasma fibrinogen, which is the major factor of the coagulation system, in patients with esophageal cancer. METHODS: From February 1995 to December 2006, 100 patients with esophageal cancer who had their plasma fibrinogen measured were enrolled. The associations between plasma fibrinogen, clinicopathological factors, and prognosis were analyzed...

BACKGROUNDS AND AIM: No well-established treatment strategies exist for lateral margin positivity (LM+) alone after endoscopic resection (ER) of early gastric cancer (EGC). Thus, we aimed to clarify treatment strategy of non-curative resection (non-CR) with LM + alone after ER in EGC. METHODS: Among 2,065 patients with EGC treated by ER, 76 (3.6%) exhibiting only LM+ after non-CR of EGC were reviewed retrospectively. Of these, 28 underwent gastrectomy, 25 argon plasma coagulation (APC), and 23 re-ER...

REVIEW

The production of neutrophil extracellular traps (NETs) is a process that enables neutrophils to help catch and kill bacteria. However, increasing evidence suggests that this process might also occur in noninfectious, sterile inflammation. In this Review, we describe the role of NETosis in autoimmunity, coagulation, acute injuries and cancer, and discuss NETs as potential therapeutic targets. Furthermore, we consider whether extracellular DNA is always detrimental in sterile inflammation and whether the source is always NETs...

INTRODUCTION: Warfarin anticoagulation of oncologic patients with DVT may paradoxically progress to phlegmasia cerulea dolens and limb gangrene, due to cancer-associated disseminated intravascular coagulation. This case report, written in line with the SCARE criteria, endorses venous thrombectomy in selected patients to attempt limb salvage. A young woman's warfarin associated acute ileofemoral phlegmasia that developed over cervical cancer radiation therapy induced DVT, was successfully resolved by clot removal...

It is well recognized that solid organ transplantation can transmit bacterial infection, chronic viral hepatitis as well as certain cancers. As indications for liver transplantation have expanded, it has been used to treat and even cure certain genetic cholestatic disorders, urea cycle defects and coagulation abnormalities; many of these conditions are potentially transmissible with liver transplantation as well. It is important for clinicians and transplant patients to be aware of these potentially transmissible conditions as unexplained post-liver transplant complications can sometimes be related to donor transmission of disease and thus should prompt a thorough exploration of the donor allograft history...

BACKGROUND: Recent data suggest that intensity-modulated radiation therapy (IMRT) plus brachytherapy boost for unfavorable prostate cancer provides improved biochemical relapse-free survival over IMRT alone. Stereotactic body radiation therapy (SBRT) may be a less invasive alternative to brachytherapy boost. Here, we report the 3-year gastrointestinal (GI) and genitourinary (GU) toxicities of IMRT plus SBRT boost. MATERIALS AND METHODS: Between March 2008 and September 2012, patients with prostate cancer were treated with robotic SBRT (19...

PURPOSE: Extracting ovarian tissue before oncologic therapy and transplanting it afterwards are increasingly being used to preserve fertility in women. This study describes standardized and safe operative procedures, with few complications, and reports the resulting ovarian function and pregnancy rates. METHODS: The standardized operative techniques for removing and transplanting ovarian tissue used at the Erlangen center are: for tissue removal, one-third to half of the tissue from one ovary is excised with scissors, without tissue coagulation; for subsequent transplantation, pieces of ovarian tissue are placed in a retroperitoneal pocket without closure of the pocket...

Clinical observations have shown that the boundary of tumor ablation is often less than safe border and that the use of radiofrequency ablation (RFA) in the treatment of hepatocellular carcinoma (HCC) may probably accelerate its recurrence and metastasis. RFA can cause the formation of a transition zone between normal liver tissues and necrotic coagulation, where blood stagnation and thrombosis expose residual cancer cells to a hypoxic microenvironment. As the blocked vessels are slowly reperfused, the oxygen supply is gradually restored...

Hiromasa Tanaka, Masaru Hori
An innovative approach for producing reactive oxygen and nitrogen species is the use of non-thermal atmospheric pressure plasma. The technique has been applied in a wide variety of fields ranging from the micro-fabrication of electric devices to the treatment of disease. Although non-thermal atmospheric pressure plasmas have been shown to be clinically beneficial for wound healing, blood coagulation, and cancer treatment, the underlying molecular mechanisms are poorly understood. In this review, we describe the current progress in plasma medicine, with a particular emphasis on plasma-activated medium (PAM), which is a solution that is irradiated with a plasma and has broadened the applications of plasmas in medicine...

When 150 years ago Armand Trousseau proposed that some thrombotic events might be the first sign of concealed visceral malignancies, these findings seemed to be just of anecdotal interest. Since then, however, we have learned that adenocarcinomas, including pancreatic cancers could be associated with a wide spectrum of paraneoplastic syndromes. They may precede the detection of the tumor, may occur simultaneously or may develop during its progression. Due to various hematologic, endocrine, cutaneous, articular, neuromuscular, renal or even psychiatric syndromes, their correct interpretation is intriguing, and because their early signs are not necessarily recognized first by oncologists, the paraneoplastic syndromes pose a diagnostic challenge...

REVIEW
Tarun Rustagi, Ankit Chhoda
Radiofrequency ablation (RFA) is a well-established technique to ablate dysplastic and neoplastic tissue via local thermal coagulative necrosis. Despite the widespread use in management of several cancers, the application of RFA in pancreas has been limited due to the increased risks of complications from the increased sensitivity of pancreatic tissue to thermal injury and proximity to vascular and biliary structures. RFA has been successfully used during laparotomy for locally advanced pancreatic carcinoma but requires an invasive approach...

214 Background: To relieve the dysphagia is a critical treatment for advanced esophageal cancer patients' palliative care in their end-of-life. The ideal way is to satisfy both the patient's nutrition supplement and self-taste. Although several endoscopic dilation techniques have been reported, the high incidence of dysphagia quickly relapsing remains. The aim of this study was to compare the effect of Argon Plasma Coagulation (APC) combined with Savary bougienage (SB) and SB alone for the relief of dysphagia of esophageal squamous cancer in the end-of-life...
