Management of Malignant Pleural Effusions with Indwelling Pleural Catheters or Talc Pleurodesis
Bibliographic record
Abstract
BACKGROUND: Management of malignant pleural effusion typically involves insertion of an indwelling pleural catheter (IPC) or chemical pleurodesis with agents such as talc. OBJECTIVES: To compare these management strategies with regard to success of pleural effusion management. METHODS: A retrospective cohort study was designed comparing patients with malignant and paramalignant pleural effusions and Eastern Cooperative Oncology Group performance status <4 managed with IPC insertion or talc pleurodesis (TP) through tube thoracostomy during noncontemporary three-year periods at a single centre. RESULTS: The IPC and TP groups comprised 193 and 167 patients, respectively. The pleural effusion control rate at six months was higher in the IPC group (52.7% versus 34.4% in the TP group; P<0.01), but the rate of freedom from catheter at 90 days and pleural effusion at 180 days was not significantly different (IPC 25.8% versus TP 34.4% [P=0.17]). Median effusion-free survival from the date of catheter insertion was significantly longer in the IPC group (101 days versus 58 days in the TP group; log-rank P=0.025). Both procedures were safe. DISCUSSION: While the results suggest better pleural effusion control and longer effusion-free survival with IPC insertion compared with TP, the present study had several limitations. Other recent studies have not shown one strategy to be clearly superior to the other. CONCLUSION: Both IPC insertion and TP remain acceptable options for the management of malignant pleural effusions.

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.
