Abstract
BACKGROUND: Indwelling pleural catheters (IPC) are commonly used in the management of malignant pleural effusions (MPE). The effect of systemic chemotherapy on IPC removal has not been reported previously. OBJECTIVES: The purpose of this study is to identify the effect of chemotherapy on the removal of IPCs in breast cancer patients with MPEs. METHODS: In this retrospective cohort study at an academic tertiary-care center, patients with breast cancer and MPE who received an IPC between 2006 and 2016 were identified from a prospectively collected database. Patient chemotherapy data were obtained, as well estrogen receptor (ER) and human epidermal growth factor receptor-2 status at the time of diagnosis. Patients receiving chemotherapy while their IPC was in situ were compared to those who did not. The primary outcome was time to IPC removal. All patients were followed until IPC removal or death. RESULTS: A total of 207 patients and 216 IPCs were included in the analysis. There was no difference in time to IPC removal between the chemotherapy and no-chemotherapy groups (HR 0.73, 95% CI 0.50-1.07, p = 0.10) or rate of IPC removal (OR 1.16, 95% CI 0.68-1.98, p = 0.59). The risk of IPC infection was not different between patients who received chemotherapy and those who did not (RR 0.57, 95% CI 0.06-5.39, p = 0.48). CONCLUSIONS: Treatment with chemotherapy with an IPC in situ was not associated with a reduced time to IPC removal in our breast cancer population. IPC insertion in patients receiving chemotherapy is safe and not associated with an increased risk of infection.

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 it
