Abstract
Purpose: There are well known negative consequences associated with the diagnosis, management and treatment of prostate cancer.We sought to determine what the perceived unmet information and supportive care needs of Canadian prostate cancer patients were according to treatment.Methods and Materials: Surveys were conducted in 2014-15 using a random sample of men diagnosed with PC in 2012 from three provincial cancer registries (BC, AB, SK).Survey questions included demographics, treatment received, information and support needs.Participants were asked if they had met or unmet needs within last two months regarding 42 topics included in six domains: physical, psychological, sexual, care and support, health information, and prostate cancer-specific.An unmet need (UMN) was defined in the survey as a need that was not fully met as a result of having prostate cancer or its treatments.Results: Provincial response rates ranged from 46%-55%.Patients (n = 810) were grouped into the following treatment categories: active surveillance (AS) (n = 37), watchful waiting (n = 25), surgery (S) (n = 294), S+external beam radiotherapy (EBRT) (n = 24), S+EBRT+hormone therapy (HT) (n = 22), EBRT (n = 68), EBRT+HT (n = 100), brachytherapy (BT) (n = 112), BT+HT (n = 19), EBRT+BT (n = 16), EBRT+BT+HT (n = 30), HT (n = 47), chemotherapy (CT) (n = 16).The mean total number of UMN (maximum 42) ranged from 1.8 to 8.5 across treatment groups.Patients who received local therapies had a higher mean total number of UMN (mean = 3.8) compared to AS (mean = 2.3) (p = 0.034).Treatment groups differed in mean UMN in the five physical domain questions (p = 0.001).Patients receiving CT (mean = 1.6) or EBRT+BT+HT (mean = 0.7) had higher UMN than all others (all means < 0.5).The groups also differed in their mean UMN in the eight prostate cancer specific domain topics (p = 0.04).CT patients had the highest UMN (mean = 1.7).Patients undergoing AS (mean = 0.4) had fewer UMN compared to radiation treatments (BT+HT, EBRT+BT+HT, EBRT+HT) (means = 0.9-1.3).Patients receiving BT+HT (mean = 1.3) had higher UMN compared to EBRT or BT alone (mean = 0.6 for each).Groups also differed in their mean UMN in the nine psychological domain topics (p = 0.05).CT patients (mean = 2.5) had higher UMN than other groups (means = 0.4-1.6).Surgical patients had higher sexual UMN (mean = 0.8) compared to other radiation local therapies (means=0.4-0.6)(p < 0.05) and AS (mean = 0.4) (p = 0.034).UMN regarding cancer fears, uncertainty, sexual feelings and relationships, loss of manhood or hot flushes were reported at high frequency (> 20%) in at least four of the treatment groups.Conclusions: There is a range of UMN for men with PC across different domains and differences between treatment groups.Identification of high UMN may serve as impetus to further address these needs by the healthcare system and community.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
