This paper introduces a novel approach for predicting symptom escalation in chemotherapy patients by leveraging Convolutional Neural Networks (CNNs). Accurate forecasting of symptom escalation is crucial in cancer care, as it enables timely interventions and enhances symptom management, ultimately improving patients' quality of life during treatment. The analytical dataset consists of daily self-reported symptom logs from chemotherapy patients, capturing a variety of symptoms such as nausea, fatigue, and pain. However, the data was significantly imbalanced, with approximately 84% of entries showing no symptom escalation. To address this issue and enhance the model's ability to identify symptom escalation, the data was resampled into varying interval lengths, ranging from 3 to 7 days. This resampling allows the model to detect notable changes in symptom severity over different time frames. The study's results show that shorter intervals (3 days) delivered the best performance, achieving an accuracy of 79%, a precision of 85%, a recall of 79%, and an F1 score of 82%. As the interval length increased, both accuracy and recall declined, though precision remained relatively consistent. These findings illustrate the capability of CNN-based models to capture temporal patterns in symptom progression effectively. Incorporating such predictive models into digital health platforms could empower healthcare providers to offer more personalized, proactive care, allowing for earlier interventions that may reduce symptom severity and improve adherence to treatment.
本文介绍了一种利用卷积神经网络(CNN)预测化疗患者症状加重情况的新方法。准确预测症状加重在癌症护理中至关重要,因为它能实现及时干预并加强症状管理,最终改善患者治疗期间的生活质量。分析数据集由化疗患者每日自我报告的症状记录组成,涵盖了多种症状,如恶心、疲劳和疼痛。然而,数据严重不平衡,约84%的记录显示没有症状加重。为解决此问题并提高模型识别症状加重的能力,数据被重新采样为3至7天不等的不同时间间隔长度。这种重新采样使模型能够检测不同时间范围内症状严重程度的显著变化。研究结果表明,较短的时间间隔(3天)表现最佳,准确率达到79%,精确率为85%,召回率为79%,F1分数为82%。随着时间间隔长度增加,准确率和召回率均下降,不过精确率保持相对稳定。这些发现表明基于CNN的模型能够有效捕捉症状进展中的时间模式。将此类预测模型纳入数字健康平台可以使医疗保健提供者提供更个性化、主动式的护理,实现更早的干预,这可能减轻症状严重程度并提高治疗依从性。
