Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Background:

Accurate risk prediction for breast reconstruction with tissue expanders (TEs) is crucial for patient counseling and shared decision-making.
Alloplastic breast reconstruction involves complex factors influencing patient outcomes.
Developing robust predictive models can optimize surgical planning and patient management.

Purpose of the Study:

To develop and evaluate traditional statistical and machine learning (ML) models for predicting complications in alloplastic breast reconstruction.
To compare the performance of ML models against traditional statistical methods in risk prediction.
To identify key predictors of complications such as TE loss, infection, and seroma.

Main Methods:

Retrospective collection of patient data, surgical techniques, and complications for women undergoing immediate TE placement (2017-2023).
Development of multivariable logistic regression and ML models to predict TE loss, infection, and seroma.
Optimization of ML models using ten-fold cross-validation and hyperparameter tuning; evaluation via AUC, sensitivity, specificity, and Brier score.

Main Results:

Analysis of 6,513 immediate TE placements in 4,046 women; complication rates: TE loss (7.6%), infection (10%), seroma (11.5%).
ML models achieved higher predictive accuracy (AUCs 0.71-0.73) compared to traditional regression (AUCs 0.63-0.69).
SHAP analysis identified BMI, prepectoral placement, and chemotherapy as significant predictors; models were integrated into nomograms and a web application.

Conclusions:

Developed accurate risk prediction tools, including nomograms and ML models, for alloplastic breast reconstruction complications.
Findings support integrating statistical and ML analyses into preoperative assessments for personalized, data-driven patient care.
Enhanced risk prediction can improve outcomes and patient satisfaction in breast reconstruction surgery.
