Introduction: The objective of this research is to identify commonly occurring patterns in limb volume (LV) changes in breast cancer survivors before the development of lymphedema. The identified patterns can be used to identify survivors at greater risk and provide opportunity for an appropriate early intervention. Methods: Perometric and circumferential LV was recorded for 233 breast cancer patients participating in a 30-month study consisting of one preoperative and eight postoperative visits. The LV changes between successive visits for every patient were calculated and categorized as increased, decreased, or stable based on 3% volume change. Patterns in volume changes before a patient met the 5% BMI-adjusted LV change criterion were recorded using episode mining. The study participants were divided into groups based on BMI. For each of these groups, the probability of a LV change pattern resulting in lymphedema was calculated. Results: The probability that a particular pattern resulted in lymphedema varied by BMI group. For example, when the LV remained stable between two visits and then increased over the next two visits, there was a 14.71% probability of a normal BMI person developing lymphedema by the next visit. The same pattern resulted in a probability of 27.27% and 44% for an overweight BMI person and an obese BMI person, respectively. Conclusion: Temporal analysis may be used to identify breast cancer survivors at increased risk of developing LE by monitoring changes in LV over time. These findings can be used to target early interventions for risk reduction and management of lymphedema.
