Emergency room imaging in patients with genitourinary cancers: analysis of the spectrum of CT findings and their relation to patient outcomes

AbstractPurposeTo assess the spectrum of computed tomography (CT) findings in patients with genitourinary cancers visiting the emergency room (ER) and evaluate the relationship between CT findings and overall survival (OS).MethodsRetrospective analysis of consecutive patients with genitourinary cancers undergoing CT during an ER visit at a tertiary cancer center during a 20-month period. CTs were considered positive if there were findings relevant to the presenting complaint(s). Demographic/clinical variables were recorded. OS was evaluated using Kaplan-Meier curves. Univariate and multivariate Cox proportional hazards regression (HR) was used to evaluate OS predictors.ResultsTwo hundred twenty-seven patients (243 visits) were included. The most common primary tumors were prostate (121 [49.8%]), bladder/urothelial (78 [32.1%]), and renal (69 [28.4%]). Common presenting complaints were abdominal pain (67 [27.6%]), respiratory symptoms (49 [20.2%]), neurological signs (37 [15.2%]), and fever (34 [14.0%]). CT findings were positive in 172 patients (70.8%) and included new/increased metastases (21.4% [52/243]), fluid collections (7.4% [18/243]), urinary tract infection/inflammation (6.2% [15/243]), enteritis/colitis (5.3% [13/243]), and pneumonia (4.9% [12/243]). A positive ER CT was associated with patient admission (p = 0.01). At multivariate analysis, independently predictive factors of shorter survival were positive ER CT (HR = 2.09 [95% CI 1.16&nd...

Do you folks have any ideas for my next PIP? I did the back pain one a few years ago and it wasn't too bad. Can I do same one (from AAPMR) again? The other projects don't really pertain to my practice. Any other recommendations?

ConclusionThe proposed multiparametric MRI-based SLICs+MTh method performs noninvasive assessment of NACT response in osteosarcoma that may improve cancer treatment monitoring, planning, and overall prognosis.Key Points• The simple linear iterative clustering supervoxels and Otsu multithresholding-based technique (SLICs+MTh) successfully estimates the proportion of necrosis, viable tumor, and edema in osteosarcoma in the course of chemotherapy.• The proposed technique is noninvasive and uses multiparametric MRI to measure necrosis as an indication of anticancer treatment response.• SLICs+MTh-based necrosis w...

ConclusionsThe e-ASPECTS software generates robust values for e-ASPECTS and acute infarct volumes when using ST ≤ 4 mm with ST = 1 mm yielding the best performance for predicting baseline stroke severity and clinical outcome after 90 days.Key Points•Clinical utility of automatically derived ASPECTS from computed tomography scans was shown in patients with acute ischemic stroke and treatment with mechanical thrombectomy.•Thin slices (=  1 mm) had the highest clinical utility in comparison with thicker slices (2–10 mm) by having the strongest correlation...

CONCLUSIONS: The average patient is middle aged (often male) with a history of subacute back pain, sometimes presenting fever and/or neurological damage on diagnosis. Acute phase reactants are frequently raised. Diabetes mellitus, endocarditis and immunosuppressed patients may have the worst chance of a good outcome, therefore these patients should be more carefully managed (always try to obtain an imaging-guided biopsy, correct antibiotic treatment, and a functional and clinical follow-up).
