Abstract

fetched live from OpenAlex

Abstract Objective: Patient reports of their symptom burden (i.e., patient-reported outcomes or PROs) have been shown to direct clinicians’ ability to personalize care and improve outcomes. A disciplined assessment of PRO in the population of patients with penile cancer (PeCa) has not previously been undertaken. Our center has both a significant cadre of patients with PeCa and a significant experience with a well-established PRO: the Edmonton Symptom Assessment Scale (ESAS).Methods: After IRB approval, we screened ESAS surveys of 14,781 patients completed between 2/2017 and 2/2021. Of these, those with PeCa were divided into three cohorts: (A) Those after any partial penectomy procedure without lymph node dissection (LND); (B) Those after partial penectomy procedure with LND; and (C) Those after total penectomy and LND. Patients with recurrent disease were analyzed separately. ESAS scores were collated and compared both by individual symptom and cumulatively.Results: 22 PeCa patients completed 122 ESAS surveys in this time and are included in this analysis: a median of 4 ESAS surveys (mean=5, range=1-19) were completed by each patient. The symptom with the highest median ESAS score was Tiredness (3.00). Patients with recurrent disease had the highest cumulative symptom score (median score = 30). Patients after total penectomy with LND had a higher cumulative symptom score (14.4) than those with partial penectomy and LND (7.9).Conclusions: PROs provide an insight into the morbidity of therapies for PeCa, and the most symptoms are reported by patients with recurrent disease.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
