Axillary web syndrome assessment using a self-assessment questionnaire: a prospective cohort study

Effectiveness of physical therapy in axillary web syndrome after breast cancer: a systematic review and meta-analysis

BACKGROUND

The axillary web syndrome (AWS) is a surgical breast cancer sequel that limits the functionality of the patient and delays the protocol times of application of cancer treatments. This implies a long period of discomfort and limitations for the user.

OBJECTIVE

To investigate the different physiotherapy treatments for the AWS and how effective they are.

METHODS

A systematic review based on PRISMA protocol and registered in PROSPERO (CRD42021281354) was conducted. The research was performed using PubMed, Scopus, CINAHL, PEDro, and Web of Science databases during January 2022 and March 2022. All randomized controlled trials and controlled clinical trials were included in this review.

RESULTS

A total of 188 articles were identified, with 9 studies selected for the systematic review. These studies basically propose treatments based on exercises and stretching, manual therapy, and the combination of manual therapy and exercises.

CONCLUSIONS

Exercise and stretching are the most effective therapies within the field of physiotherapy for the rehabilitation of axillary web syndrome. They restore range of motion faster, reduce pain, improve quality of life, and reduce disabilities. Manual therapy, scar massage, and myofascial release could help improve outcomes but with worse results. The meta-analysis conclusion is that pain is the only outcome with a significant reduction after the application of physiotherapy treatments - 0.82 [- 1.67; 0.03]. This conclusion is drawn from the only three studies with small sample sizes.

Tolerability, Safety and Efficacy of a Specific Rehabilitation Treatment Protocol for Axillary Web Syndrome: An Observational Retrospective Study

Axillary web syndrome (AWS) is a highly prevalent surgical complication affecting BC survivors. It presents as a subcutaneous cording that limits the upper limb range of motion (ROM) and causes pain. Its etiology is still debated, and its treatment is not well defined. Therefore, we aimed to investigate the safety, tolerability and efficacy of our specific AWS rehabilitative treatment protocol. We conducted an observational retrospective study on a cohort of 92 AWS patients referred to the oncological outpatient service of a university hospital. We collected data from medical records before (T0) and after (T1) the treatment. The studied protocol was composed of 60-min sessions, carried out 3 times/week by specialized physiotherapists, until the clinical resolution of AWS. We found that a mean of 8.74 ± 2.12 rehabilitative sessions were needed, and only one patient stopped early. At T1, shoulder ROM was complete in both abduction and flexion in 98% of patients; AWS was no longer detectable in 64% of them, and pain significantly decreased compared to T0. In conclusion, our protocol proved to be safe, well-tolerated and seemed to be effective in treating AWS.

Randomised clinical trial of a manual therapy programme to reduce the evolution time of axillary web syndrome in women affected by breast cancer: study protocol

INTRODUCTION

Breast cancer is the most common malignant tumour in women, with more than 2 million new cases annually worldwide. One of the most frequent and well-known surgical and post-actinic sequelae is post-mastectomy lymphoedema. The axillary web syndrome is another sequela that limits the functionality of the patient and delays the protocol time of administering cancer treatments; and in many cases, this sequela is misdiagnosed. This surgical sequela usually disappears spontaneously after the third month of appearance, but this implies a long period of discomfort and limitations for the patient, at the same time, it may delay the application of radiotherapy within the indicated protocol deadline (due to a need for body posture).

METHODS AND ANALYSIS

With the present quasi-experimental study, we intend to show the application of physiotherapy and stretching from the beginning of the appearance of the axillary cord, in a controlled and scheduled way by the physiotherapist. It is possible to reduce the time in which the lymphatic thrombus is present and, therefore, recover functionality and mobility, reduce pain and be able to apply treatments within the established deadline. We intend to apply this therapy into the intervention group and compare thrombus evolution time with the control group.

ETHICS AND DISSEMINATION

This trial has the approval of the Andalucía Ethics Committee (PEIBA code 1909-N1-21, reg. number 171.21).

TRIAL REGISTRATION NUMBER

Five-Year Cumulative Incidence of Axillary Web Syndrome and Comparison in Upper Extremity Movement, Function, Pain, and Lymphedema in Survivors of Breast Cancer With and Without Axillary Web Syndrome

OBJECTIVE

To determine the cumulative incidence and natural history of axillary web syndrome (AWS) and its related postoperative risk for physical impairments in a cohort of women followed for 5 years post breast cancer surgery.

DESIGN

Prospective, longitudinal study.

SETTING

Academic health center.

PARTICIPANTS

Women (N=36) with and without AWS after breast cancer surgery with sentinel node biopsy or axillary lymph node dissection.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Participants were assessed for AWS, shoulder goniometric flexion and abduction range of motion, function (Disability of the Arm, Shoulder, and Hand), lymphedema (bioimpedance spectroscopy, girth measures, tissue dielectric constant), and pain (visual analog scale) at 2, 4, 12, and 78 weeks and 5 years after breast cancer surgery. Analysis of variance compared range of motion, function, lymphedema, and pain in women identified with AWS with those without AWS across visits. Univariate logistic regression assessed if AWS was a risk factor for physical impairment at 5 years.

RESULTS

The cumulative incidence of AWS was 57%. Fifty percent (14/28) of the women who completed all study visits had signs of AWS at 5 years. Abduction active range of motion was significantly lower in women with AWS at 2 and 4 weeks post surgery. AWS was identified as a risk factor for reduced shoulder motion at 5 years. Regardless of AWS, 75% of the women experienced 1 or more upper extremity physical impairments at 5 years, which is an increase from 66% at 78 weeks in the same cohort.

CONCLUSIONS

AWS is associated with reduced shoulder range of motion in the early postoperative time period, can persist for 5 years after breast cancer surgery, and increases the risk of long-term reduced shoulder range of motion. Long-term physical issues are apparent after breast cancer surgery regardless of AWS.

Lymphoscintigraphic Investigations for Axillary Web Syndromes

Background: Axillary web syndrome (AWS) is a frequent complication after surgery for breast cancer, but its lymphatic involvement is not definitively established. Here we report the results of lymphoscintigraphic investigations in patients with AWS. Methods and Findings: We conducted a retrospective, single-center review of lymphoscintigraphic investigations performed in 46 patients with AWS that was either clinically obvious or suspected. Of this group, 23 patients had two investigations with a mean interval of 19 weeks between them (range, 6-98 weeks). Results of the lymphoscintigraphic investigations, which were performed according to a well-standardized protocol, were classified into four patterns: normal; functional lymphatic insufficiency only (no lymphatic vascular morphologic abnormality); lymphovascular blockade without collateralization; and vascular collateralization and/or dermal backflow. Of the 46 patients, on the first lymphoscintigraphic investigation, four (8.6%) had a normal pattern, seven (15.2%) had functional lymphatic insufficiency only, four (8.6%) had lymphovascular blockade without collateralization, and 31 (67.3%) had vascular collateralization and/or dermal backflow. Among patients who underwent two investigations, four of the five who had only functional lymphatic insufficiency at the first investigation had developed vascular collateralization and/or dermal backflow by the second. The three patients who had lymphovascular blockade without collateralization at the first examination had also progressed to collateralization and/or dermal backflow at the second. None of the 15 patients who initially had vascular collateralization and/or dermal backflow showed any reversal at the second examination. Conclusions: Our analysis confirms the lymphatic nature of AWS and shows the lymphoscintigraphic patterns and evolutions of the lymphatic lesions with potential therapeutic implications. The retrospective review of our database is approved by the institutional ethics committee under number 2048.

Prevalence and associations of axillary web syndrome in Asian women after breast cancer surgery undergoing a community-based cancer rehabilitation program

Background

Patients who have breast cancer surgery are at risk of axillary web syndrome (AWS), an under-recognized postsurgical complication which can result in shoulder morbidity and functional impairment. Emerging studies have indicated that AWS may persist beyond the first few months after surgery, although few studies have assessed the prevalence and association of AWS beyond a year after diagnosis. Therefore, the aim of this study was to investigate the prevalence and associations for AWS in post-operative breast cancer patients up to 3 years after surgery.

Methods

This cross sectional observational study was conducted at a community-based cancer rehabilitation center. Patients were evaluated for the presence of AWS via physical examination. Disease-related data was obtained from clinical review and medical records. Descriptive statistics were utilized to illustrate patient demographics and clinical characteristics. Logistic regression analyses were used to determine associations of AWS.

Results

There were 111 Asian women who were recruited, who had undergone breast surgery and were referred to a national outpatient rehabilitation center. The prevalence of AWS in this population was 28.9%. In the multivariate regression model, significant factors were age < 50 years (OR = 3.51; 95% CI = 1.12–11.0; p = 0.031) and ALND (OR = 6.54; 95% CI = 1.36–31.3; p = 0.019). There was reduced shoulder flexion ROM (p < 0.001) in patients with AWS compared to patients without AWS.

Conclusions

A high prevalence of AWS was reported in breast cancer survivors even at 3 years after breast surgery. Our findings highlight the need to identify breast cancer survivors with AWS even in the survivorship phase, and develop strategies to raise awareness and minimize functional impairment in these patients.

Axillary web syndrome among Chilean women with breast cancer: incidence and possible predisposing factors

PURPOSE

Breast cancer (BC) is the most common cancer in women worldwide. The main treatment for BC is surgery, which involves an axillary procedure that associates with the development of axillary web syndrome (AWS). The incidence of AWS among Chilean women with BC and its possible predisposing factors are currently unknown. Thus, we aimed to (1) determine the incidence of AWS among Chilean women with BC after surgery and (2) identify possible predisposing factors.

METHODS

Within 90 days post-surgery, patients were assessed for AWS, i.e., palpable or visible axillary cords in the axillary region extending down from the mid-axilla to the ipsilateral arm. We then computed the odds ratio with 95% confidence interval (OR [95% CI]) for having AWS considering the following predisposing factors: age, body mass index (BMI), number of lymph nodes removed, axillary procedure, days from surgery to the physical therapy assessment, hospital for the surgery, type of breast surgery, and neoadyuvant chemotherapy.

RESULTS

AWS was present in 49 out of 107 patients (45.8%). Younger age and lower BMI appeared as the sole predisposing factors for AWS (age, 0.95 [0.91-0.99]; BMI, normal weight 1.00, overweight 0.35 [0.11-1.12], obesity 0.28 [0.08-0.97]).

CONCLUSION

The incidence of AWS among Chilean women with BC was 45.8%. Our study also confirms data from previous reports showing that younger age and low BMI are associated with the development of AWS.

Review of axillary web syndrome: What the radiologist should know

Axillary web syndrome is common after axillary surgery, frequently affecting breast cancer patients. In this condition, patients develop one or more linear bands of firm tissue, also known as "cords", in the axilla and arm, associated with pain and limited range of motion of the shoulder and arm. Radiologists may encounter this syndrome in patients referred for axillary or upper extremity ultrasound, and should be aware of the physical examination and ultrasound findings for accurate diagnosis. However, there are currently limited articles about this syndrome published in radiology journals, suggesting that radiologists may be unaware of this entity. In this work, axillary web syndrome will be discussed, including background knowledge, incidence, clinical presentation, possible etiology, and ultrasound appearance.

Axillary web syndrome following breast cancer surgery: symptoms, complications, and management strategies

Axillary web syndrome (AWS) is a common condition occurring in up to 86% of patients following breast cancer surgery with ipsilateral lymphadenectomy of one or more nodes. AWS presents as a single cord or multiple thin cords in the subcutaneous tissues of the ipsilateral axilla. The cords may extend variable distances "down" the ipsilateral arm and/or chest wall. The cords frequently result in painful shoulder abduction and limited shoulder range of motion. AWS most frequently becomes symptomatic between 2 and 8 weeks postoperatively but can also develop and recur months to years after surgery. Education about and increased awareness of AWS should be promoted for patients and caregivers. Assessments for AWS should be performed on a regular basis following breast cancer surgery especially if there has been associated lymphadenectomy. Physical therapy, which consists of manual therapy, exercise, education, and other rehabilitation modalities to improve range of motion and decrease pain, is recommended in the treatment of AWS.
