Abstract
290 Background: Hepatocellular carcinoma (HCC) is a fatal cancer without curative option for most patients. Hence the importance to improve health related quality of life (HRQoL). Amplitude-modulated radiofrequency electromagnetic fields (EMF), as a novel and non-toxic therapy, has potential for improving HRQoL in advanced HCC patients. Methods: An open-label, single center, prospective clinical protocol was performed in advanced HCC patients as an initial and salvage treatment modality. Systemic exposure to EMF was used in combination with a systemic conventional treatment or as a single treatment. A spoon-shaped antenna placed in the oral cavity delivered EMF over 90 minutes with monthly repetitions until death or consent withdrawal. The effect on HRQoL was the primary objective of this study. Patients answered the EORTC-C30 v3.0 questionnaires prior to every EMF exposure. Clinically meaningful change (CMC) and time to deterioration (TTD) for Global Health (QoL), Role Functioning (RF) and Physical Functioning (PF) were used in the analysis. Results: From March 2018 to April 2020, 55 advanced HCC patients were submitted to 373 EMF exposures. 41/55 (75%) patients had repetitive exposures (mean # 4, ranging from 2-16). 87% were male, median age was 67, 84% were BLCL-C, 16% were Child-Pugh B, 29% had extra-hepatic metastasis, 55% had failed previous treatment and 71% had documented radiological progression. 31(56%) patients received EMF in combination with systemic therapy (28 TKI and 3 anti-PDL1). 24 patients received EMF as a single treatment modality. The mean baseline score was 68.1 for QoL and 77.1 for RF and PF. 61%, 76% and 49% of patients experienced positive change in QoL, RF and PS scores immediately prior to the second exposure, respectively. +CMC was reported in 20%, 17% and 32% of patients, respectively for QoL, RF and PS. The median QoL TTD was not reached. The median RF TTD was 7.2 month and the median PF TTD was 11.9 month. The median RF TTD for patients in combination treatment was 11.4 months and in a single treatment was 13.5 month. The median PF TTD for patients in combination treatment was 12.8 months and in single treatment was 14.5 month. Conclusions: Advanced HCC patients showed positive changes in QoL, RF and PF HRQoL scores after single exposure to EMF. The benefit from EMF in HRQoL was durable both in combination with TKI or as a single modality in advanced HCC patients. These results support future development as a novel palliative treatment modality in advanced HCC patients. Clinical trial information: NCT 01686412.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
