Background: There is insufficient clear epidemiological and clinical knowledge about lymphedema patient’s population in Mexico, this limits its investigation. The objective of this study is to present basic lymphedema epidemiological data and its clinical characteristics based on the analysis of lymphedema patients’ data collected from a specialized rehabilitation clinic in Mexico. Methods: This is a cohort study developed between 2015 and 2021. The study was carried ou in a private clinic specialized in oncological and peripheral vascular patients’ rehabilitation. Clinical assessments and interviews were performed to collect each case’s clinical history, considering its medical characteristics, physical activity and functionality and socio-demographic information, classified in a matrix, and later statistically evaluated. Results: Among 446 lymphedema patients, gender distribution was represented by 81% female and 19% male with a mean age of 50.5 years (±44.5). The population was categorized into the following three different study groups according to diagnosis: Cancer-Related Lymphedema (CRL), Non-Cancer-Related Secondary Lymphedema (NCRSL) and Primary Lymphedema. 60.08% of the patients had CRL; 25.11% had NCRSL and 14.79% had Primary Lymphedema. Among the patients with CRL, 81% of them corresponded to breast cancer diagnosis, the rest were associated to 19 different cancer diagnoses. The most prevalent diagnosis was breast CRL 48.6%; phlebolymphedema 19.4%; congenital and praecox lymphedema 14.1%; lipo-lymphedema 4.8%. The BMI of 64% of the patients ranged in overweight and obesity. 37.6% of patients reported that had experienced pain in limbs affected by lymphedema and 45% of all patients reported some disability to perform one or more activities associated to their limb volume or limb discomfort. 82% of patients had no physical activity or performed less physical activity than what is suggested to their population group’s recommendation. Conclusion: This study stablishes a precedent on reporting the broadest available epidemiological and clinical data of lymphedema in Mexico. Further studies are needed to report with a higher precision the epidemiological, clinical, and demographical data about each etiological group for a better understanding of lymphedema in Mexico and Latin America.

Backgroundː There is a lack of clinical and epidemiological knowledge about cancer-related lymphedema in Mexico. The objective of this study is to present a broad and deep report of cancer-related lymphedema’s clinical characteristics and epidemiological features based on the analysis of CRL patients’ data, collected from a specialized rehabilitation clinic in Mexico. Methodsː This is a cohort study based on the analysis of clinical data gathered between 2015 and 2022. The study was developed in a private clinic that specializes in oncological patients’ rehabilitation. Clinical assessments and interviews were performed to collect each case’s clinical history, considering diverse clinical characteristics and demographic information, classified in a matrix, and statistically evaluated. Resultsː Among 307 lymphedema patients, gender distribution was represented by 87.9% (270) female and 12.1% (37) male; mean age of 54.5 years (± 32.5); 79.8% of the patients corresponded to breast cancer diagnosis, the rest of them were associated with other 19 different types of cancer. 90.2% of patients underwent some lymph node removal procedure, 68.1% of patients received fractioned radiotherapy sessions, and 87.7% received some chemotherapy scheme treatment. 64% of patients had a diagnosis of lymphedema and had onset symptoms of lymphedema in the first 5 years after oncological interventions and/or cancer diagnosis, most of them during the first 2 years. The general distribution of clinical staging was: 23.7% in stage 0; 20.1% in stage I; 44.6% in stage II, and in stage III 11.4%. Regarding body mass index, it was found a mean of 26.7 BMI. 61.2% of patients ranged between overweight and obesity. 43.3% of patients with CRL reported a disability to perform one or more activities due to lymphedema. 80% of patients had no physical activity or performed under the minimal physical activity recommended for the population group they belong. Conclusionː This study reports broad epidemiological and clinical features of a group of cancer-related lymphedema patients in Mexico, it was possible to identify diverse potential factors and relations that influence the clinical features of CRL; it is necessary to explore all factors and the interactions among them for a better understanding of CRL patients in the country.

Background: The clinical features and epidemiological data about patients with phebolymphedema or lymphedema related to Chronic Venous Disease in Mexico is limited and has been understudied; at the same time, the relationships between its clinical features, physical activity level and disability remained unknown. Methods: This is a longitudinal cohort study based on the analysis of clinical data of 90 patients gathered between 2021 and 2022. The statistical analysis was carried out using the software SPSS version 25 and GrandhPad Prism 8; a descriptive analysis was developed using measures of central tendency for the variables of a quantitative nature and frequency distribution for those categorical variables. The behavior of the variables was revealed through the Shapiro-Wilk statistic. The mean difference analysis was carried out with the Student’s T for independent samples. To identify the effect of gender, age, and severity of the disease on the study variables, a three-way analysis of variance was obtained with a Sidak comparison analysis. For the associations between qualitative and dichotomous nature variables, the Chi-Square statistic was obtained along with the odds ratio to determine the intensity of the relationships found. Results: A total of 90 patients were included in the analysis; 71% (64) were female and 29% (26) were male; with a mean age of 62.7 years old (± 30.5). A mean BMI of 33.2, 79.9% (77) of patients reached overweight and obesity ranges. 50% (45) of patients reported disability to perform one or more daily life activities related to the disease’s condition (signs, symptoms, volume). Only 12% (10) of all patients performed at or above the minimum physical activity recommended for their population group, and 88% (80) of patients had no physical activity or performed under the proper population group’s recommendation of minimal physical activity. It was found that the practice of physical activity, the number of compromised segments, the stage of the pathology, and the presence of cardiological and metabolic antecedents provide a statistically significant association with disability. Notable statistical difference among sex as a risk factor was not found. Regarding the BMI, the only differences were observed in the level of severity of the disease, regardless of the presence of any disability (p=0.006), evidencing that the greater the severity, the higher the BMI in both men and women. About physical activity, it is observed that inactivity or minimal practice of physical activity is a risk factor for referred disability (p<0.05), since it is prolonged that the non-practice of physical activity increases by 230% the chances of referring a disability associated to the disease compared to those people who referred to practice minimal or above minimal physical activity; the presence of a cardiological and/or metabolic history is related to an increase of about 150% to 180% of presenting disability compared to patients who do not have these pathologies. Conclusion: This study shows clinical and epidemiological features of phlebolymphedema and their relationship with the level of physical activity and reported disability of 90 patients. Further studies are needed to improve and broaden the understanding of the clinical characteristics of phlebolymphedema and its correlations.
