Summary
This summary is machine-generated.Predicting cancer symptom trajectories is possible using past experiences. Machine learning models, including LSTM, outperform traditional methods for better patient care and quality of life.
Area Of Science
- Oncology
- Medical Informatics
- Computational Biology
Background
- Accurate prediction of cancer symptom severity and progression is crucial for timely clinical intervention and treatment planning.
- Current prediction methods are often limited by sparse, inconsistent data and simplistic measures like last observed symptom severity.
- Developing robust predictive models is essential for improving patient outcomes and quality of life in cancer care.
Purpose Of The Study
- To develop and evaluate a predictive model for future cancer symptom experiences based on historical symptom data.
- To compare the performance of different machine learning models in predicting symptom trajectories.
- To leverage routinely collected nursing documentation for enhanced cancer symptom prediction.
Main Methods
- Retrospective, longitudinal analysis of 208 hospitalized cancer patients' records (2008-2014).
- Training and evaluation of Long Short-Term Memory (LSTM) recurrent neural networks, linear regression, and random forest models.
- Models were trained on past symptom data to predict future symptom trajectories.
Main Results
- At least one tested model (LSTM, linear regression, random forest) surpassed predictions based solely on previous clinical observation.
- LSTM models significantly outperformed linear regression and random forest in predicting nausea and psychosocial status.
- Linear regression excelled in predicting oral health, while random forest was superior for mobility and nutrition predictions.
Conclusions
- Routinely collected nursing documentation, even with sparse data, can be used to successfully predict patient symptom trajectories.
- The developed prediction models can aid in individualizing symptom management strategies for cancer patients.
- Improved symptom prediction has the potential to significantly support cancer patients' quality of life.

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...
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
Predicting Outbreaks
Predictive analytics, a branch of statistics, uses historical data, algorithmic models, and...
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...
