Surgical approach to lymphedema of the arm after mastectomy

Evaluation and Management of the Fat Leg Syndrome

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Discuss the initial evaluation of a patient presenting with lower extremity enlargement. 2. Distinguish underlying medical conditions causing lower extremity enlargement, including lymphedema and lipedema. 3. Discuss appropriate management and treatment for patients presenting with these conditions.

BACKGROUND

Given the epidemic of obesity in the United States, many patients will consult the plastic surgeon with complaints of lower extremity enlargement secondary to "fat legs." In addition to cosmetic disfigurement, some patients may suffer from underlying medical conditions that are responsible for their symptoms. Knowledge of these other causes, including lymphedema and a disorder of abnormal fat deposition known as lipedema, ensures appropriate management and/or surgical treatment for affected patients.

METHODS

Initial evaluation for lower extremity enlargement should include a discussion of pertinent medical history and a focused physical examination for findings that might indicate a pathologic underlying cause. When indicated, patients should undergo additional testing, including radiologic studies, to confirm their diagnoses.

RESULTS

For those patients found to have lymphatic dysfunction, conservative management, such as massage therapy, use of compression garments, and limb elevation, should be initially recommended. Excisional or suction-assisted lipectomy may be considered in patients who fail conservative therapy. More extensive consultation with the plastic surgeon is recommended for patients seeking aesthetic improvement in contour and shape of large legs without a specified underlying abnormality.

CONCLUSIONS

Patients with lower extremity enlargement may present to the plastic surgeon unsure of the specific cause of their deformity. A broad differential diagnosis exists for their presentation, which can be narrowed by using the common features and unique manifestations of the conditions.

Debilitating lymphedema of the upper extremity after treatment of breast cancer

Lymphedema after mastectomy occurs with a frequency as high as 30%. The incidence increases with more radical surgical dissection, as was often seen with radical mastectomies in the late 1800s. This is one aspect of breast surgery that has been greatly neglected. Surgery has often been deemed a success if the malignancy is eradicated. Patients may complain of symptoms as minor as arm heaviness to major ones such as massive chronic swelling, as was the case with our patient. The patient presented here had increasing lymphedema during a 14-year period after modified radical mastectomy and radiation therapy for advanced breast cancer. This condition had progressed to incapacitation of the extremity and a patient who as a result had become an invalid. The massively edematous extremity revealed no signs of recurrent disease or malignant degeneration. She underwent surgical intervention and physical therapy as procedures of choice to restore function.

Lymphoedema following surgery for breast cancer

BACKGROUND

Lymphoedema is a common complication of breast cancer treatment, affecting approximately a quarter of patients. Those affected can have an uncomfortable, unsightly and sometimes functionally impaired limb prone to episodes of superficial infection. The aetiology, pathophysiology and management of these patients is poorly understood.

METHODS

This is a systematic review of all published literature on lymphoedema following treatment for breast cancer, using the Medline and Cinahl databases with cross-referencing of major articles on the subject up to the end of 1999.

RESULTS AND CONCLUSION

The aetiology and pathophysiology of lymphoedema in patients with breast cancer appear to be multifactorial and are still not fully understood. Although conservative treatment techniques can be very successful in controlling symptoms, they do not afford a cure. The place of surgical and pharmacological therapy remains unclear. Improved understanding of the pathophysiology may assist in reducing the incidence of this condition, or help to identify those at greatest risk, in whom early initiation of conservative treatment measures may prove effective.

Overview of treatment options and review of the current role and use of compression garments, intermittent pumps, and exercise in the management of lymphedema

BACKGROUND

Lymphedema is a relatively frequent complication following the management of breast carcinoma. Numerous therapeutic interventions have been offered to treat this potentially disabling and disfiguring condition. Consensus has not been attained among oncologists, surgeons, psychiatrists, and physical therapists concerning the appropriate treatment of lymphedema.

METHODS

This review provides an overview of those treatment regimens that have been used in the past and, in some instances, have gone on to provide the foundation for the most widely prescribed interventions currently employed for the management of upper extremity lymphedema following breast carcinoma treatment. The use of intermittent pneumatic compression pumps as a part of an integrated multidisciplinary treatment approach incorporating garments, exercises, and massage also is discussed.

RESULTS

A review of available literature suggests that a variety of traditional and commonly available techniques, when used appropriately in a multidisciplinary fashion, may lessen the cosmetic and physical impairments associated with acquired lymphedema. The role of surgery is unclear. Pharmacotherapies are a promising adjunct to manual and mechanical therapies.

CONCLUSIONS

The appropriate use of readily available treatment approaches may lessen the severity of acquired lymphedema following breast carcinoma therapy. A comprehensive therapeutic approach should be employed in the management of lymphedema, including attention to the functional, cosmetic, and emotional sequelae of this potentially disabling condition. To that end, a recommendation for a comprehensive treatment regimen is provided.

Staged skin and subcutaneous excision for lymphedema: a favorable report of long-term results

Numerous surgical procedures have been proposed for the management of lymphedema. The postoperative results vary, and unfortunately none of the procedures are curative. As a result, some degree of recurrence of leg edema is seen in all patients postoperatively. Reported here is a long-term follow-up of patients with lower extremity lymphedema managed by skin and subcutaneous tissue excision. Thirty-eight patients (6 male; 32 female) with lower extremity lymphedema have been followed up for an average of 14 (3 to 27) years after staged subcutaneous excisions performed beneath skin flaps. Seven patients had been treated previously by other procedures. Of the 38 lymphedema patients, 10 patients developed edema after pelvic or groin ablative surgery, radiation therapy, or both. Results were documented by various methods: physical examination, circumferential measurements, volume displacement, serial photography, lymphoscintigraphy, and patient survey. Of these, it is believed that photographs are the easiest and as representative as any other method, all of which have great variability. Of the 38 patients, 30 patients had significant and long-lasting reduction in extremity size associated with improved function and extremity contour. Episodes of recurrent cellulitis were reduced or completely eliminated. No differences in the long-term results were seen in patients with acquired as opposed to congenital lymphedema. Men did not have as much improvement as women. Two patients had no change in leg swelling, and six patients (three men) had progressive swelling after surgery. Partial wound separation occurred immediately postoperatively in one patient, and three patients had loss (less than 2 cm) of the skin flap, all in the ankle region. None of these instances required further surgery, and no other significant complications were encountered. Staged skin and subcutaneous excision beneath skin flaps appears to provide long-lasting improvement for lower extremity lymphedema, regardless of cause, in the majority of patients treated.

Focused review: postmastectomy lymphedema

Upper extremity lymphedema is a relatively frequent complication following the management of breast cancer. This focused review of the pathophysiology, complications, and various treatment options now available for its management will allow physiatrists and other practitioners to better understand this condition and thereby serve as a resource for patients and other physicians.

Cardiovascular, pulmonary, and cancer rehabilitation. 3. Cancer rehabilitation

This self-directed learning module highlights several important rehabilitation aspects in the care of persons with cancer. It is part of the chapter on cardiovascular, pulmonary, and cancer rehabilitation in the Self-Directed Physiatric Education Program for practitioners and trainees in physical medicine and rehabilitation. This article discusses the organization of a cancer rehabilitation team, unique rehabilitation issues presented by specific common tumors, and the impact of common complications on successful rehabilitation outcomes.

Selection of breast-preservation therapy for primary invasive breast carcinoma

Breast-preservation treatment for primary breast cancer should not be used for all women. Women frequently excluded from consideration for such treatment or who choose not to have it may be elderly and not concerned about cosmetic appearance or live at a distance so that 6 weeks of daily trips to radiotherapy would be inconvenient or even impossible. Also, if radiotherapeutic expertise or facilities are not available, a breast-preservation program is difficult. In Massachusetts, a full course of just over 6000 cGy (4500 cGy to the whole breast and a 1600-cGy local boost) costs roughly $6000. Thus, breast preservation is more expensive than mastectomy even with reconstruction, as patients still frequently require a hospital admission with general anesthesia for an axillary dissection. Although insurance policies cover such expenses, patients who do not have insurance or have inadequate coverage may find the extra expense of the breast-preservation technique burdensome or impossible. Women with a small breast and a proportionately large cancer may have an unsatisfactory cosmetic outcome after appropriate lumpectomy. The cosmetic result in such patients frequently cannot be predicted beforehand; this fact adds emphasis to the need for a two-step process of lumpectomy and then re-evaluation of the cosmetic outcome as well as pathologic features for decisions regarding breast preservation. Finally, women may have strikingly different attitudes toward breast preservation than expected by the surgeon. For some women, the urge to preserve the breast is so strong that they will accept virtually any risk to achieve this option, whereas for other women, the constant anxiety about a recurrence or undergoing radiation therapy is traumatic enough that they readily accept mastectomy. In our referral surgical oncology practice, roughly 60% of patients are currently treated with breast-preservation techniques; the remainder undergo mastectomy, with immediate reconstruction in approximately three fourths of the cases. The proportion of patients who elect to have breast preservation depends greatly on local medical customs and attitudes; the radiotherapeutic skills available; women's attitudes, which frequently are dependent on the local press and publicity; and the surgeon's interest and enthusiasm for such a program. There is no appropriate proportion of patients who should be treated by breast-preservation techniques, but clearly, the proportion of patients so treated increases with experience, acceptability, publicity, and availability. Thus, the selection of breast-preserving therapy for individual patients is a result of an extraordinary array of factors that need to be considered in each patient.(ABSTRACT TRUNCATED AT 400 WORDS)
