Conclusion: The dose to the parotid glands increases as a result of the changes that occur during the course of radiation. The changes are significant after 15 fractions of radiation. A replanning at this juncture might be considered to reduce the dose to the parotid glands.
CONCLUSIONS: Our model predicts percent free flap volume loss in a significant fashion. Age and RF are individual predictors of free flap volume loss, the latter being a novel finding that is also modifiable through hyperfractionation radiotherapy schedules.

ConclusionsNew foci of increased18F-fluorodeoxyglucose avidity are commonly seen in the caudate and left hepatic lobes of the liver during neoadjuvant chemoradiation for distal esophageal cancer, and these findings generally reflect radiation-induced liver disease rather than metastatic disease. Awareness of the pitfalls of a high18F-fluorodeoxyglucose uptake in radiation-induced liver injury is crucial in order to avoid misinterpretation and overstaging. Except for the location of18F-fluorodeoxyglucose uptake, the shape of the lesion, and an maximum standardized uptake value (> 10/h), a convincing liver magneti...
ConclusionWe do not recommend routine panendoscopy for all oral squamous cell cancer patients. Esophagogastroduodenoscopy benefitted smoking patients primarily concerning the secondary diagnosis of inflammation of the upper digestive tract. Selective bronchoscopy, esophagogastroduodenoscopy, and oropharyngolaryngoscopy should be performed if clinical examination or medical history indicates risks for additional malignancies of the upper aerodigestive tract.Clinical relevanceRoutine panendoscopy is not recommended in all, especially not in low-risk oral cancer patients like non-smokers and non-drinkers.

We report a rare case of acute bowel obstruction due to multiple bilateral deep intestinal endometriosis lesions localised in the ileum, ileocaecal valve and upper rectum, requiring synchronous resection in an emergency setting. A 42-year-old woman was referred to our clinic with a diagnosis of obstructing Crohn's disease based on abdominal computed tomography with oral contrast showing a thickened terminal ileum with stenosis, compression of the caecum and proximally dilated small bowel loops. Simultaneous ileocaecal resection and segmental resection of the upper rectum with handsewn end-to-end anastomosis between the sig...
ConclusionsThe enhancement of SLNs in CTL images after iopamidol injection should be compared sufficiently with CT images before iopamidol injection to avoid overlooking of SLNs in N0 early oral cancer.
Conclusions: We have identified two PET imaging biomarkers for detection of response in patients treated with combined EGFR/glutamine metabolism-targeting therapy. These biomarkers could serve as an innovative imaging approach to help guide precision medicine by matching patients with cancer to the ideal treatment. This study could lead to critical advances in the treatment of CRC, as well as for other cancer types, by elucidating the mechanism of action of therapies targeting glutaminolysis.
1299Objectives: To demonstrate the feasibility of zero-echo-time (ZTE) MR imaging for jaw bones and to evaluate the quantitative performance of 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) PET/MRI with ZTE-based attenuation correction (ZTE-AC) compared with PET/CT and PET/MRI with Dixon-MR-based AC (MR-AC) in patients with oral cavity cancer (OCC). Methods: Thirteen patients with OCC underwent a whole-body 18F-FDG PET/CT scan and a subsequent regional PET/MR scan with MR-AC and ZTE-AC in one day. The standardized uptake values (SUVs) were measured on PET/CT (SUVCT-AC), PET/MRI with MR-AC (SUVMR-AC), and with ZTE-AC (SUVZTE-A...
