Twenty patients with chronic lymphedema had been treated by microwave heating. T-lympocyte subpopulation and HLA-DR phenotype of peripheral blood in patientswith lymphedema were examined by using dual colour flow cytometry before and after treatment. We found that CD4 (T helpe/inducer) in chronic lymphedema decreased significantly (Plt;0.01), HLA-DR increased significantly (P lt;0.05). After the microwave treatment, the CD4, CD4/CD8 ratio increased significantly; HLA-DR, HLA-DR+CD+8 lymphocyte reduced. It was clear that microwave could regulate the immunological disorder of lymphedema patients.
Objective To study a new method of treatment for upper limb lymphedema after radical mastectomy. Methods From Jun. 2001 to Sep. 2003, 11 cases(2with complication of erysipelas ) of upper limb lymphedema being treated with radical mastectomy for more than 2 years were used as model. All the edema of limbs was sucked from hypodermis with liposuction technique and compressed with compression garment. Three months after operation, elasticity stress was conducted every night. Results The reduction of the edema of upper limbswas remarkable. The average decrease of circumference was 4 cm. No erysipelas was observed. Conclusion The liposuction technique and elasticity stress is a new and effective approach to the treatment of upper limb lymphedema.
Thirteen cases of unilateral lymphedema of lower extremity were treated by the anastomosis between the suporficial and deep lymphaties. The rate of subeidence of edema at 2 weeks and 6 months after operation were 57.1±18.5%and 47.3± 22.9%, respectively, It was believed that this type of oporation had the advantageS of anastomosis on the tissues of same origin, unlikely occurrence of thrombosis at the anastomotic stoma, small incision, less surgical trauma and acceptable by patients.
Objective To review the current progress of clinical and experimental research of vascularized lymph node transfer for lymphedema. Methods The domestic and abroad literature about vascularized lymph node transfer in treatment of lymphedema was reviewed and analyzed. Results Experimental studies in animal model indicate that vascularized lymph node transfer can improve lymph node survival and show a promising effectiveness in reducing lymphedema. " Lymphatic wick” and " lymph pump” were the two main hypotheses proposed to explain the potential functional mechanism of vascularized lymph node transfer in treatment of lymphedema. Improvement in lymphedema symptoms are reported in most of the clinical trials, but the level of evidence to advocate this procedure in the treatment of lymphedema remains low because of the small number of the cases and problems in their methodologies. Conclusion Based on current evidence, vascularized lymph node transfer seems to be a promising treatment for lymphedema, but long-term well-designed studies are required to further explore the effectiveness of this procedure.
Objective To review the clinical progress of microsurgical management for lymphedema. Methods The literature on microsurgical treatment for lymphedema at home and abroad in recent years was reviewed and analyzed. Results At present, conservative treatment is the main treatment for lymphedema, which has limited effectiveness only for early stages of lymphedema; and it is not curative and demands patient compliance. In contrast, microsurgical approaches can solve the problems in the prevention or management of lymphedema and showed promising results, such as lymphatic-venous anastomosis (LVA), vascularized lymph node transfer (VLNT), and other lymphatic reconstructions. Conclusion Microsurgical approaches like LVA and VLNT have been broadly used in recent years, the effectiveness and safety have been proved. But the evidence of long-term randomized controlled studies is still required to establish standard treatment practices.
ObjectiveTo investigate the therapeutic effect of modified side-to-end lymphaticovenular anastomosis in the treatment of post-mastectomy upper limb lymphedema. MethodsBetween May 2010 and May 2011, 11 female patients with post-mastectomy upper limb lymphedema underwent a modified side-to-end lymphaticovenular anastomosis. The average age was 49.5 years (range, 38-55 years). Lymphedema occurred at 7-30 months (mean, 18.3 months) after resection of breast cancer, with an average disease duration of 25.5 months (range, 10-38 months). The left upper limb was involved in 5 cases and the right upper limb in 6 cases. In accordance with difference value between health and affected sides criteria, 5 cases were rated as moderate, and 6 cases as severe. ResultsModified side-to-end lymphaticovenular anastomosis was successfully completed in all patients. Primary healing of incision was obtained in the other patients except 1 case of delayed healing. All patients were followed up for an average of 38.4 months (range, 36-40 months). Limb pain and swelling were relieved; no episodic attack or recurrence was observed. The circumference of affected upper arm was significantly decreased from preoperative (33.9±3.7) cm to postoperative (31.0±3.5) cm at 6 months and (30.9±3.5) cm at 36 months (P<0.05), but no significant difference was found between at 3 and 6 months (P>0.05); the circumference of affected forearm was significantly decreased from preoperative (30.1±3.6) cm to postoperative (27.8±3.4) cm at 6 months and (27.7±3.3) cm at 36 months (P<0.05), but no significant difference was shown between at 6 and 36 months (P>0.05). According to Campisi evaluation standard to assess efficacy, the results were excellent in 3 cases, good in 6 cases, and improved in 2 cases. ConclusionUsing modified side-to-end lymphaticovenular anastomosis may be effective in the treatment of upper limb lymphedema after mastectomy.
ObjectiveTo systematically review the effect of self-management intervention on the prevention and management of lymphedema in breast cancer patients. MethodsThe Cochrane Library, Embase, PubMed, Web of Science, CINAHL, PsycINFO, SinoMed, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on self-management intervention on the prevention and management of lymphedema in breast cancer patients, from inception to June 16. Two reviewers independently screened the literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed using RevMan 5.4 software. ResultsA total of 37 references were included, comprising 25 randomized controlled trials (RCTs), 12 controlled clinical trials (CCTs), and a total of 3 697 patients. There were 26 studies in the meta-analysis, and the results of the meta-analysis showed that, compared with the control group, patients in the intervention group exhibited better performance in lymphedema management-related behaviors (SMD=2.65, 95%CI 1.53 to 3.78, P<0.01), symptoms related to lymphedema (SMD=−2.01, 95%CI −3.66 to −0.37, P<0.05), occurrence of lymphedema (RR=0.37, 95%CI 0.32 to 0.45, P<0.01), upper limb function (SMD=−1.88, 95%CI −2.83 to −0.92, P<0.01), quality of life (SMD=2.79, 95%CI 2.05 to 3.54, P<0.01), and the difference was statistically significant. The intervention mainly included information support, material support, emotional support and decision support. ConclusionThere are currently a variety of self-management interventions, but they mainly focus on information support. Self-management interventions can improve the self-management behavior of breast cancer patients with lymphedema and reduce the impact of lymphedema on patients.
By using biochemical assessment technique and histological examination,a comparative study of the cutaneous tissues in 16 patients with lymphedema of the lower extremity before and after the heating and bandage therapy, and it was noted thatthe heating and bandage therapy might:(1) the content of hydroxyproline in the affected skin would be decreased; (2) the thickness of skin was decreased and the water content was reduced; (3) the microcirculation of local tissues was enhanced, and (4) the activity of the macrophages was increased. In conjunction with the criteria of clinical observation, the action mechanism of heating and bandage therapy might be as follows: (1) improve the local microcirculation and enhance the resorption of tissue fluid and the protein, and (2) increase the activity of the macrophages, and minimize the extent of fibrosis of the affected tissues.
ObjectiveTo explore the feasibility and the practical value of conserving upper limb lymph nodes in axillary lymph node dissection (ALND) for early breast cancer. MethodsFrom August 2007 to January 2010, 124 patients with early breast cancer were studied and divided into two phases: phase one, from August 2007 to July 2008; phase two, from August 2008 to January 2010. Five milliliter of methylene blue was injected subcutaneously in ipsilateral forearm in all the patients before operation to locate the upper limb lymph nodes. Routine ALND was performed in 22 patients of phase one. The level Ⅱ lymph nodes and the upper limb lymph nodes were separated from the axillary lymph nodes, respectively. The lymph nodes of level Ⅱ were investigated by combining touch cytology with frozen section during operation. The lymph nodes of level Ⅰ, Ⅱ, Ⅲ, and the upper limb lymph nodes were investigated postoperatively by routine pathological examination to evaluate the feasibility of conserving the upper limb lymph nodes. One hundred and two patients in phase two were divided randomly by lottery into control group (30 cases), and conserving group (72 cases) in which upper limb lymph nodes were selectively conserved. The surgical procedure for control group was same as the phase one blue stained upper limb lymph nodes, in the conserving group were conserved selectively when the lymph nodes metastasis of level Ⅱ were not detected by combining touch cytology with frozen section during operation. The data were collected and analysed on pathological results of all patients and arm circumference was compared between control group and conserving group. Results Total 119 of 124 patients (96.0%) were found with blue stained upper limb lymph nodes. The concordance rate was 99.2% (123/124) between the intraoperative combining pathological method and the postoperative routine pathological examination. No upper limb lymph node metastasis was found in the phase one and the control group of phase two with level Ⅱ group negative. The incidence of arm lymphedema in the control group and the conserving group with level Ⅰ and Ⅱ lymph nodes dissection was 18.2% （4/22） and 20% （1/51）, respectively on 6 months after operation. The difference was statistically significant （χ 2=6,34， Plt;0.05）. ConclusionsMethylene blue being injected subcutaneously in ipsilateral upper limb can be used to show validly lymph nodes of upper limb in the axillary region. ALND with selectively conserving upper limb lymph nodes when level Ⅱ lymph nodes negative in metastasis, can prevent postoperative arm lymphedema.
ObjectiveTo review the progress of treatment and prevention of breast cancer related lymphedema. MethodsThe recent literature concerning treatment and prevention of breast cancer related lymphedema was extensively consulted and reviewed. ResultsThe treatment of lymphedema is now based on complete decongestive therapy, supplemented with medicine and surgery. Those procedures have been proved to be safe and effective. Sentinel lymph node biopsy, axillary reverse mapping, and lymphaticovenous anastomoses have been used to decrease the incidence of lymphedema. They show promising effectiveness in short term, but the long-term effectiveness needs further tests. ConclusionIn clinical practice, many treatment methods are used to decrease lymphedema, and lymphedema prevention is playing an increasingly important role. Lymphaticovenous anastomoses shows a promising effectiveness in reducing lymphedema.
