Prognostic Value of Thrombus Volume and Interaction With First-Line Endovascular Treatment Device Choice
Patient satisfaction and quality of life before and after treatment of pancreatic and periampullary cancer:A prospective multicenter study
Background: This study sought to assess patient satisfaction and quality of life (QoL) before and after treatment of pancreatic and periampullary cancer. Methods: We conducted a prospective multicenter study of patients treated for pancreatic and periampullary cancer. General patient satisfaction was measured using the EORTC satisfaction with care questionnaire (IN-PATSAT32) at baseline and 3 months after treatment initiation, with a 10-point change on the Likert scale considered clinically meaningful. QoL was measured using the EORTC Core Quality of Life Questionnaire (QLQ-C30). The influence of treatment (curative and palliative) on patient satisfaction and QoL was determined. Results: Of 100 patients, 71 completed follow-up questionnaires. General satisfaction with care decreased from 74.3 before treatment to 61.9 after treatment (P<.001), whereas global QoL increased from 68.4 to 71.4 (P=.39). Clinically meaningful reductions were also observed for the reported interpersonal skills of doctors (from 73.4 to 63.3) and exchange of information within the care team (from 63.5 to 52.5). Satisfaction scores were lower for patients treated with curative intent than for those treated with palliative intent regarding interpersonal skills of doctors (P=.01), information provision by doctors (P=.004), information provision by nurses (P=.02), availability of nurses (P=.004), exchange of information within the care team (P=.01), and hospital access (P=.02). In multivariable analysis, clinicopathologic or QoL factors were not independently associated with general patient satisfaction. Conclusions: Satisfaction with care, but not QoL, decreased after pancreatic cancer treatment. Improvements in communication and interpersonal skills are needed to maintain patient satisfaction after treatment

Thrombus radiomics in patients with anterior circulation acute ischemic stroke undergoing endovascular treatment
Background: Thrombus radiomics (TR) describe complex shape and textural thrombus imaging features. We aimed to study the relationship of TR extracted from non-contrast CT with procedural and functional outcome in endovascular-treated patients with acute ischemic stroke. Methods: Thrombi were segmented on thin-slice non-contrast CT (≤1 mm) from 699 patients included in the MR CLEAN Registry. In a pilot study, we selected 51 TR with consistent values across two raters' segmentations (ICC >0.75). Random forest models using TR in addition or as a substitute to baseline clinical variables (CV) and manual thrombus measurements (MTM) were trained with 499 patients and evaluated on 200 patients for predicting successful reperfusion (extended Thrombolysis in Cerebral Ischemia (eTICI) ≥2B), first attempt reperfusion, reperfusion within three attempts, and functional independence (modified Rankin Scale (mRS) ≤2). Three texture and shape features were selected based on feature importance and related to eTICI ≥2B, number of attempts to eTICI ≥2B, and 90-day mRS with ordinal logistic regression. Results: Random forest models using TR, CV or MTM had comparable predictive performance. Thrombus texture (inverse difference moment normalized) was independently associated with reperfusion (adjusted common OR (acOR) 0.85, 95% CI 0.72 to 0.99). Thrombus volume and texture were also independently associated with the number of attempts to successful reperfusion (acOR 1.36, 95% CI 1.03 to 1.88 and acOR 1.24, 95% CI 1.04 to 1.49). Conclusions: TR describing thrombus volume and texture were associated with more attempts to successful reperfusion. Compared with models using CV and MTM, TR had no added value for predicting procedural and functional outcome
Prognostic Value of Thrombus Volume and Interaction With First-Line Endovascular Treatment Device Choice
BACKGROUND: A larger thrombus in patients with acute ischemic stroke might result in more complex endovascular treatment procedures, resulting in poorer patient outcomes. Current evidence on thrombus volume and length related to procedural and functional outcomes remains contradicting. This study aimed to assess the prognostic value of thrombus volume and thrombus length and whether this relationship differs between first-line stent retrievers and aspiration devices for endovascular treatment.METHODS: In this multicenter retrospective cohort study, 670 of 3279 patients from the MR CLEAN Registry (Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands) for endovascularly treated large vessel occlusions were included. Thrombus volume (0.1 mL) and length (0.1 mm) based on manual segmentations and measurements were related to reperfusion grade (expanded Treatment in Cerebral Infarction score) after endovascular treatment, the number of retrieval attempts, symptomatic intracranial hemorrhage, and a shift for functional outcome at 90 days measured with the reverted ordinal modified Rankin Scale (odds ratio >1 implies a favorable outcome). Univariable and multivariable linear and logistic regression were used to report common odds ratios (cORs)/adjusted cOR and regression coefficients (B/aB) with 95% CIs. Furthermore, a multiplicative interaction term was used to analyze the relationship between first-line device choice, stent retrievers versus aspiration device, thrombus volume, and outcomes.RESULTS: Thrombus volume was associated with functional outcome (adjusted cOR, 0.83 [95% CI, 0.71-0.97]) and number of retrieval attempts (aB, 0.16 [95% CI, 0.16-0.28]) but not with the other outcome measures. Thrombus length was only associated with functional independence (adjusted cOR, 0.45 [95% CI, 0.24-0.85]). Patients with more voluminous thrombi had worse functional outcomes if endovascular treatment was based on first-line stent retrievers (interaction cOR, 0.67 [95% CI, 0.50-0.89]; P=0.005; adjusted cOR, 0.74 [95% CI, 0.55-1.0]; P=0.04). CONCLUSIONS: In this study, patients with a more voluminous thrombus required more endovascular thrombus retrieval attempts and had a worse functional outcome. Patients with a lengthier thrombus were less likely to achieve functional independence at 90 days. For more voluminous thrombi, first-line stent retrieval compared with first-line aspiration might be associated with worse functional outcome.</p
