Abstract

fetched live from OpenAlex

PURPOSE: This descriptive study compares overall survival (OS) and locoregional control (LRC) rates between cisplatin-etoposide (EP) and carboplatin-etoposide (EC) at a population level in patients with limited disease (LD) and extensive disease (ED) small cell lung cancer (SCLC). MATERIALS AND METHODS: All patients diagnosed with SCLC from January 2004 to December 2008 were identified. Patients with LD SCLC treated with EP or EC and concurrent or sequential radiotherapy and those with ED SCLC treated with EP or EC were included for analysis. A retrospective review examining prognostic features and outcomes was performed. OS and LRC curves were calculated using the Kaplan-Meier method and compared with the log-rank test. RESULTS: A total of 249 patients with LD SCLC and 287 patients with ED SCLC were identified. Patients treated with EC were significantly older for both LD (median 62 vs. 72, P<0.001) and ED (median 62 vs. 73, P<0.001). Median follow-up times were 37 and 22 months for LD and ED SCLC, respectively. Median OS for EP and EC in LD SCLC patients were 23 and 18 months (P=0.10). LRC rates at 12 months were 81% for the EP group and 68% for the EC group (P=0.97). Median OS for the EP and EC patients with ED SCLC was 10 and 11 months, respectively, (P=0.24). CONCLUSION: Despite the preferential use of EC in an older population, median OS and LRC rates were not significantly different for patients treated with EP for both LD and ED SCLC.

Teacher imitation

Not 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.
