Fatigue, a highly prevalent and distressing symptom during chemotherapy (CTX), demonstrates diurnal and interindividual variability in severity. Little is known about the associations between variations in genes involved in inflammatory processes and morning and evening fatigue severity during CTX. The purposes of this study, in a sample of oncology patients (N=543) with breast, gastrointestinal (GI), gynecological (GYN), or lung cancer who received two cycles of CTX, were to determine whether variations in genes involved in inflammatory processes were associated with inter-individual variability in initial levels as well as in the trajectories of morning and evening fatigue...

REVIEW
Falk Roeder, Robert Krempien
Soft-tissue sarcoma (STS) represent a rare tumor entity, accounting for less than 1% of adult malignancies. The cornerstone of curative intent treatment is surgery with free margins, although the extent of the surgical approach has been subject to change in the last decades. Multimodal approaches usually including radiation therapy have replaced extensive surgical procedures in order to preserve functionality while maintaining adequate local control. However, the possibility to apply adequate radiation doses by external beam radiation therapy (EBRT) can be limited in some situation especially in case of directly adjacent organs at risk with low radiation tolerance...

BACKGROUND: Cytoreductive surgery followed by hyper- thermic intraperitoneal chemotherapy (HIPEC) has shown better oncological outcomes in peritoneal surface malignancies (PSM). We assessed the feasibility and perioperative outcomes of this procedure in Indian patients. METHODS: In this prospective observational study from February 2013 to April 2015, we included 56 patients (41 females, 73.2%) with PSM. They had a good performance status, were either treatment-naïve or previously treated by surgery and systemic chemotherapy...

BACKGROUND: Surgical site infections (SSI) remain a major source of morbidity and cost after resection of intra-abdominal malignancies. Negative pressure wound therapy (NPWT) has been reported to significantly reduce SSI when applied to the closed laparotomy incision. This paper reports results of a randomized clinical trial examining the effect of NPWT on SSI rates in surgical oncology patients with increased risk for infectious complications. STUDY DESIGN: From 2012-2016, 265 patients underwent open resection of intra-abdominal neoplasms stratified into three groups: gastrointestinal (n=57), pancreas (n=73), and peritoneal surface malignancy (n=135)...

Since the first laparoscopic procedure, there has been an steady increase in advanced minimally invasive surgery. These procedures include oncological colorectal, hepatobiliary and upper gastrointestinal surgery. Implementation of these procedures requires different and new skills for the surgeons who wish to perform these procedures. To accomplish this surgical teaching program, a mentorship seems the most ideal method to teach the apprentice surgeon these specific skills. At the VU medical center a teaching program for a minimally-invasive esophagectomy for esophageal cancer started in 2009...

BACKGROUND: Older patients with metastatic urothelial carcinoma (UC) are under-represented in clinical trials, and data regarding outcomes for second-line therapy is limited. MATERIALS AND METHODS: Individual data for patients with metastatic UC, aged ≥ 70 years, were pooled from 10 second-line studies. The influence of potential prognostic factors on overall survival (OS) was assessed via univariate and multivariate Cox regression analysis. RESULTS: In total, 102 patients were included; the median age was 74...

The genus Raoultella belongs to the family of Enterobacteriaceae. Raoultella spp. are Gram-negative, aerobic, non-motile rods. This genus can be distinguished from the genus Klebsiella, in that genus use histamine as the only source of carbon in the medium. Also, Raoultella grow at 4 °C and do not produce gas from lactose at 44.5 °C. Raoultella sp. is known to inhabit natural environments (water, soil, plants). The reservoir of Raoultella is the gastrointestinal tract and upper respiratory tract. Raoultella spp...

Circulating cell-free DNA (cfDNA) is DNA released from necrotic or apoptotic cells into the bloodstream. While both healthy cells and cancer cells release cfDNA, tumors are associated with higher levels of tumor-derived circulating cell-free DNA (ctDNA) detectable in blood. Absolute levels of ctDNA and its genetic mutations and epigenetic changes show promise as potentially useful biomarkers of tumor biology, progression, and response to therapy. Moreover, studies have demonstrated the discriminative accuracy of ctDNA levels for diagnosis of gastrointestinal cancer compared with benign inflammatory diseases...

The development and popularization of minimally invasive treatment is gradually evolving in the course of human fighting against disease. Minimally invasive surgery has been widely accepted and carried out because of the advantages of smaller trauma, less pain, little impact on the body and physiological metabolism of the body. The evidence-based medicine makes it important to conduct clinical trials to confirm the technical and oncological safety. With the development of minimally invasive technologies, including three-dimensional laparoscopic, natural orifice transluminal endoscopic surgery, robotic surgery system, minimally invasive surgery are providing more opportunities and challenges for gastrointestinal diseases...

PURPOSE: To investigate and characterize the radiobiological effectiveness of very high dose rate radiotherapy (FLASH) compared to conventional irradiation in an in vivo model. METHODS: The gastrointestinal (GI) tract of C57BL/6 mice were irradiated with doses ranging between 10 and 18 Gy using a custom stereotactic jig. A Varian Clinac 21EX was modified to allow dose rates ranging from 0.05 to 240 Gy/s at the position of the mirror. With the gantry at 180 degrees, the jig holding the individual animals was placed above the mirror to take advantage of the reduced source to target distance...

INTRODUCTION: To minimize the resection of stomach tissue, especially for lesions close to the esophagogastric junction or pyloric ring, we developed laparoscopic wedge resection with the serosal and muscular layers incision technique (SAMIT) for gastric gastrointestinal stromal tumors. MATERIALS AND SURGICAL TECHNIQUE: SAMIT involves resection of the mucosal and submucosal layers and then an incision in serosal and muscular layers around the tumor. SAMIT is simple and does not require special devices...

BACKGROUND: There has been a proliferation of gastrointestinal surgical fellowships; however, little is known regarding their association with surgical volume and management approaches. METHODS: Surveys were distributed to members of GI surgical societies. Responses were evaluated to define relationships between fellowship training and surgical practice with pancreatoduodenectomy (PD). RESULTS: Surveys were completed by 889 surgeons, 84.1% of whom had completed fellowship training...

BACKGROUND: Patients with advanced cancer often require complex symptom management. At Dana-Farber/Brigham and Women's Cancer Center, the intensive palliative care unit (IPCU) admits symptomatic oncology patients with uncontrolled symptoms throughout the trajectory of illness. Patients are uniquely managed by an interdisciplinary team of clinicians who focus on symptom management and advance care planning. OBJECTIVE: The purpose of our analysis was to investigate goals-of-care outcomes and healthcare utilization after admission to the IPCU...

Only a few studies have revealed using laparoscopic technique with limited resection of gastrointestinal stromal tumour (GIST) of the duodenum. A 68-year-old man was admitted to the hospital due to upper gastrointestinal (GI) bleeding. Evaluation revealed an ulcerated, bleeding GI tumour in the second part of the duodenum. After control of bleeding during gastroduodenoscopy, he underwent a laparoscopic wedge resection of the area. During 1.5 years of follow-up, the patient is disease free, eats drinks well, and has regained weight...

Oral delivery of cancer chemotherapeutic drugs (CCDs) is subject matter in the 21st century, which changes the dosage regimens of oncotherapy with enhancement in patient's life and deducts the cost of therapy. The present report explored on the nano-oncology such as polymeric nanoparticles (PNPs) as an oral CCDs delivery vehicle, showing great potential for colon cancer treatment. Proof-of-concept in vitro and in vivo results for delivery of CCDs using various oral PNPs are included in this review from the literatures...
