This paper provides imaging recommendations for pediatric abdominal tumors that arise outside of the solid viscera. These tumors are rare in children and have been categorized in two groups: abdominal...
Magnetic resonance guided radiotherapy (MRgRT) allows daily adaptation of treatment plans to compensate for positional changes of target volumes and organs at risk (OARs). However, current adaptation ...
Twenty patients receiving adaptive MRgRT for treatment of abdominal lesions were retrospectively analyzed. Magnetic resonance (MR) images acquired at the start of adaptation and immediately before irr...
A significant increase in dose constraint violations was observed from adapted (6.9%) to pre-irradiation (30.2%) dose distributions. Overall, OAR dose increased significantly by 4.3% due to intrafract...
Intrafractional organ movement can impact dose distributions and lead to violations of OAR tolerance doses, which impairs the benefit of daily on-table plan adaptation. By application of simulation im...
Postoperative delirium (POD) is a common complication in older adults, with unknown epidemiology and effects on surgical outcomes in Asian geriatric cancer patients. This study evaluated incidence, ri...
Overall, 345 patients aged ≥65 years who underwent elective abdominal cancer surgery at a medical center in Taiwan were prospectively enrolled. Delirium was assessed daily using the Confusion Assessme...
POD occurred in 19 (5.5%) of the 345 patients. Age ≥73 years, Charlson comorbidity index ≥3, and operative time >428 min were independent predictors for POD occurrence. Patients presenting with one, t...
POD occurrence was significantly associated with adverse surgical outcomes in geriatric patients undergoing elective abdominal cancer surgery, highlighting the importance of early POD identification i...
Respiratory motion presents a challenge in radiotherapy of thoracic and upper abdominal tumors. Techniques to account for respiratory motion include tracking. Using magnetic resonance imaging (MRI) gu...
The aim of this study was to quantify the error when using the right hemidiaphragm top (RHT) as surrogate for abdominal organ motion during prolonged breath-holds (PBH) for possible application in rad...
Fifteen healthy volunteers were trained to perform PBHs in two subsequent MRI sessions (PBH-MRI1 and PBH-MRI2). From each MRI acquisition, we selected seven images (dynamics) to determine organ displa...
The linear relationships were confirmed by the high R...
The RHT could serve as an accurate surrogate for abdominal organ motion during radiation treatments, for example, in tracking, provided the error of the RHT as motion surrogate is taken into account i...
The study was registered in the Netherlands Trial Register (NL7603)....
The American College of Surgeons (ACS) has developed a Surgical Risk Calculator (SRC) to predict postoperative surgical complications. No studies have reported the performance of the ACS-SRC in oncoge...
This is a retrospective study including 136 patients who underwent elective abdominal oncological surgery, between 2017 and 2019, at our institution. Postoperative complications were classified accord...
Discrimination was adequate with AUC of 0.7113 (95% confidence interval [CI]: 1.062-1.202, p = 0.0001; Brier 0.198) for serious complications and 0.7230 (95% CI: 1.101-1.756, p = 0.0057; Brier 0.099) ...
The ACS-SRC is an adequate predictor for serious complications and pneumonia in oncogeriatric patients treated surgically for abdominal cancer. However, the predictive power of the calculator appears ...
Real-time motion monitoring (RTMM) is necessary for accurate motion management of intrafraction motions during radiation therapy (RT)....
Building upon a previous study, this work develops and tests an improved RTMM technique based on real-time orthogonal cine magnetic resonance imaging (MRI) acquired during magnetic resonance-guided ad...
A motion monitoring research package (MMRP) was developed and tested for RTMM based on template rigid registration between beam-on real-time orthogonal cine MRI and pre-beam daily reference 3D-MRI (ba...
The mean (range) centroid motions for the 13 abdominal tumor cases were 7.69 (4.71-11.15), 1.73 (0.81-3.05), and 2.71 (1.45-3.93) mm with an overall accuracy of <2 mm in the superior-inferior (SI), th...
We have successfully developed and tested the use of a template-based registration method for an accurate RTMM of abdominal targets during MRgART on a 1.5T MR-Linac without using injected contrast age...
Low health literacy (HL) is associated with poor surgical outcomes in patients with abdominal tumors, despite enhanced recovery programs. However, the relationship between HL and postoperative outcome...
The prospective cohort study was conducted from April 2020 to December 2021 in a single acute care hospital in Akita City, Japan. Out of 112 consecutive older adults with abdominal tumors referred to ...
Of the 97 patients (36 [37.1%] women, mean [standard deviation] age 74.4 [6.3] years), 42 (43.3%) reported low HL. At baseline, patients with low HL exhibited worse EQ-5D-5L scores (P = .001), EQ-VAS ...
There appeared to be no apparent associations of HL with surgical outcomes in patients with abdominal tumors receiving PRPs. Thus, HL might not be a crucial predictor of surgical outcomes when combine...
To explore the efficacy and safety of remimazolam for procedural sedation during ultrasound-guided nerve block administration in patients undergoing abdominal tumor surgery, in order to improve and op...
The enrolled patients were randomly divided into three groups: 50 patients in the remimazolam group (R group), 50 patients in the dexmedetomidine group (D group), and 50 patients in the midazolam grou...
Compared with the control groups (midazolam and dexmedetomidine groups), the Narcotrend index and MOAA/S decreased more in the remimazolam group (P < 0.01). Compared with the control groups, the incid...
Remimazolam can be used safely for procedural sedation during ultrasound-guided nerve block administration in patients undergoing abdominal tumor surgery. The sedation effect is better than that with ...
This study was approved by the Ethics Committee of Anhui Provincial Cancer Hospital (Ethical Review 2021, No. 23) and registered at https://www.chictr.org.cn (ChiCTR2000035388). The pre-registration t...
The gold standard in the treatment of mucinous intra-abdominal neoplasms is cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Despite complete cytoreduction ...
A search and analysis of the current literature were carried out....
There is still controversy regarding the best treatment strategy for patients with recurrent pseudomyxoma peritonei (PMP) after CRS and HIPEC. The clinical management of these patients depends on many...
Repeated complete cytoreduction of recurrent PMP can result in long-term survival. Tumor debulking surgery may be particularly beneficial for symptomatic patients....
Incomplete cytoreduction for mucinous appendiceal neoplasms is often required to temporarily alleviate symptoms. The surgical technology for this intervention may be complex and result in extensive mo...
A database was used to identify patients who had palliative surgery that included total abdominal colectomy (TAC). Clinical- and treatment-related variables were assessed for their impact on overall s...
Seventy-eight patients had an incomplete cytoreductive surgery (CRS) that included a TAC. The median survival was 2.5 years and the median follow-up was 2 years. Patients with symptoms of abdominal di...
TAC with end ileostomy was used as a treatment option to provide palliation of patients having an incomplete CRS for appendiceal mucinous neoplasms. With LAMN or MACA-Int, median survival was 5.0 year...
