Small cell carcinoma of cervix: A population-based study evaluating standardized provincial treatment protocols
Bibliographic record
Abstract
To describe the patient characteristics, patterns of treatment, and outcome of patients with small cell carcinoma of Cervix (SmCC) treated with radical radiotherapy from a provincial cancer registry database. Overall 25 patients with SmCC were treated with radical radiotherapy (with or without chemotherapy) from January 1, 1994 to December 31, 2013. Nineteen patients had pure SmCC while 6 had additional neuroendocrine component. Patients were treated with combined chemo-radiotherapy using multi-agent chemotherapy with pelvic or combined pelvic and para-aortic radiotherapy. All patients received brachytherapy. Use of prophylactic cranial irradiation was dependent on physician discretion. Survival was estimated using Kaplan-Meier method and compared using log-rank test. We report a median overall survival of 53.8 months for our cohort. After a median follow-up of 54 months for surviving patients, the overall survival (OS) and progression free survival (PFS) at 5-years were 48% and 46.4% respectively. Patients with stage I-IIA disease had superior 5-year PFS (67.3% vs. 11.1%; p = .004) and 5-year OS (62.5% vs. 22.2%; p = .006). Patients with node-negative disease had a trend towards better 5-year PFS (55.7% vs. 19%; p = .07) and OS (61.1% vs. 14.3% at 5-years; p = .06) Distant metastasis was the predominant site of disease progression (n = 12; 48%). Distant metastasis is the predominant pattern of failure for patients with SmCC treated with radical chemo-radiotherapy. With modern chemo-radiotherapy protocols we can expect a 5 year survival of around 50%. Early stage and node-negative status appear to be favorable prognostic factors with survival rates at 5-year over 60%.

How this classification was reachedexpand
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.
