RESUMO
AIMS: We investigated whether modulation of white adipose tissue (WAT) vasculature regulates rebound weight gain (RWG) after caloric restriction (CR) in mice fed a high-fat diet (HFD). MAIN METHODS: We compared changes in energy balance, hypothalamic neuropeptide gene expression, and characteristics of WAT by RT-qPCR, ELISA, immunohistochemistry, and adipose-derived stromal vascular fraction spheroid sprouting assay in obese mice fed a HFD ad libitum (HFD-AL), mice under 40 % CR for 3 or 4 weeks, mice fed HFD-AL for 3 days after CR (CRAL), and CRAL mice treated with TNP-470, an angiogenic inhibitor. KEY FINDINGS: WAT angiogenic genes were expressed at low levels, but WAT vascular density was maintained in the CR group compared to that in the HFD-AL group. The CRAL group showed RWG, fat regain, and hyperphagia with higher expression of angiogenic genes and reduced pericyte coverage of the endothelium in WAT on day 3 after CR compared to the CR group, indicating rapidly increased angiogenic activity after CR. Administration of TNP-470 suppressed RWG, fat regain, and hyperphagia only after CR compared to the CRAL group. Changes in circulating leptin levels and hypothalamic neuropeptide gene expression were correlated with changes in weight and fat mass, suggesting that TNP-470 suppressed hyperphagia independently of the hypothalamic melanocortin system. Additionally, TNP-470 increased gene expression related to thermogenesis, fuel utilization, and browning in brown adipose tissue (BAT) and WAT, indicating TNP-470-induced increase in thermogenesis. SIGNIFICANCE: Modulation of the WAT vasculature attenuates RWG after CR by suppressing hyperphagia and increasing BAT thermogenesis and WAT browning.
RESUMO
OBJECTIVES: Acquired lymphedema of upper extremity is a chronic pathologic status that frequently occurs after breast cancer treatment. Reliable and quantitative evaluation of lymphedema is crucial for successful management of patients. Although lymphoscintigraphy is the primary investigation for the confirmation and evaluation of lymphedema, the specific protocol of stress intervention is not well established. This study aims to introduce intermittent pneumatic compression (IPC) as a part of stress lymphoscintigraphy and compare the effectiveness of conventional stress lymphoscintigraphy (CSL) and pneumatic compression-assisted lymphoscintigraphy (PCAL). METHODS: Our study was designed as a retrospective analysis of 85 breast cancer patients with lymphedema who underwent lymphoscintigraphy utilizing either IPC device or conventional stress maneuver and received complex decongestive therapy. The flow extent of the lymphatic fluid (FE) was evaluated using a 0- to 4-point scale based on lymphoscintigraphic images. The visualization of lymph nodes was also assessed. The clinical outcomes were evaluated by changes in side-to-side circumferential and volume differences of upper extremities and compared between groups. RESULTS: Of 85 patients, 47 underwent CSL, and 38 underwent PCAL. Participants with relatively preserved flow extent of the lymphatic fluid (FE 3) showed a significant difference in percentage reduction of volume (PRV) between CSL and PCAL groups ( P = 0.036). In the other groups, CSL and PCAL demonstrated comparable differences in PRV without statistical significance. CONCLUSION: Our study suggests that participants in the PCAL group with relatively preserved lymphatic flow extent (FE 3) had better PRV compared with those in the CSL group. The use of IPC devices in lymphoscintigraphy with the novel stress maneuver can help in the quantitative description of lymphedema status and the selection of an appropriate treatment method.

Chemotherapy-induced cachexia causes severe metabolic abnormalities independently of cancer and reduces the therapeutic efficacy of chemotherapy. The underlying mechanism of chemotherapy-induced cachexia remains unclear. Here we investigated the cytarabine (CYT)-induced alteration in energy balance and its underlying mechanisms in mice. We compared energy balance-associated parameters among the three groups of mice: CON, CYT, and PF (pair-fed mice with the CYT group) that were intravenously administered vehicle or CYT. Weight gain, fat mass, skeletal muscle mass, grip strength, and nocturnal energy expenditure were significantly lowered in the CYT group than in the CON and PF groups. The CYT group demonstrated less energy intake than the CON group and higher respiratory quotient than the PF group, indicating that CYT induced cachexia independently from the anorexia-induced weight loss. Serum triglyceride was significantly lower in the CYT group than in the CON group, whereas the intestinal mucosal triglyceride levels and the lipid content within the small intestine enterocyte were higher after lipid loading in the CYT group than in the CON and PF groups, suggesting that CYT inhibited lipid uptake in the intestine. This was not associated with obvious intestinal damage. The CYT group showed increased zipper-like junctions of lymphatic endothelial vessel in duodenal villi compared to that in the CON and CYT groups, suggesting their imperative role in the CYT-induced inhibition of lipid uptake. CYT worsens cachexia independently of anorexia by inhibiting the intestinal lipid uptake, via the increased zipper-like junctions of lymphatic endothelial vessel.

Background: Breast cancer-related lymphedema (BCRL) is correlated with poor quality of life (QOL). The effects of the management of lymphedema on QOL remain controversial. We analyzed the changes in QOL and identified factors associated with its improvement to improve the care of patients with BCRL. Methods and Results: A total of 194 patients with BCRL were recruited, and their medical records were reviewed regarding type of surgery, chemotherapy, and radiation. Patients completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires, and the volume and circumference of lymphedema were measured. Significant improvements in physical, emotional, cognitive, social, and role functioning, and future perspective were observed after BCRL management. However, the change in the size of lymphedema was not correlated with the change in QOL parameters. Conclusion: The management of BCRL has a beneficial effect on QOL. However, changes in the size of lymphedema did not reflect changes in QOL. Therefore, a comprehensive approach for the management of BCRL beyond reducing the size of lymphedema is recommended to improve QOL.

Despite widespread concern about energy imbalance due to tumor and chemotherapy-related side effects, little is known about detailed variations in energy input, metabolic rate, and physical activity. This study explored changes in energy balance components and serum biomarkers of patients with hematologic malignancies undergoing chemotherapy. Our prospective study included 40 patients with hematologic malignancies hospitalized for chemotherapy. We measured energy balance components, physical function, and serum biomarkers at baseline and weekly after chemotherapy for 3 weeks. Significant weight loss, representing negative energy balance, occurred at 2 (p = 0.002) and 3 weeks (p < 0.001) post-chemotherapy. Statistically reduced oral intake was observed at 3 weeks post-chemotherapy (p = 0.040), and resting energy expenditure statistically decreased according to Harris-Benedict equation, but not to Penn State University equation. Physical function according to DEMMI score decreased significantly at 3 weeks post-chemotherapy (p = 0.002). Serum biomarker analysis demonstrated significant changes in albumin, total protein, CXCL13, and GDF15, with exception of leptin. Although conventional serum biomarkers (total protein and albumin) did not reach pathological states despite their statistical differences, subgroup analysis showed CXCL13 in weight loss group and GDF15 in reduced oral intake group were significantly changed. Over half of patients (65.0%, n = 26) suffered from energy imbalance associated with weight loss and reduced oral intake during chemotherapy. Serial laboratory results suggested that novel biomarkers (CXCL13, GDF15) could be correlated with cachexic state and reduced food intake. Monitoring clinical and serum biomarkers associated with energy balance together can help identify needs for nutritional support in patients with hematologic malignancies undergoing chemotherapy.

OBJECTIVE: To compare the biomechanical properties of the glenohumeral joint capsule between adhesive capsulitis (AC) after breast cancer surgery and idiopathic AC and demonstrate the effects of hydrodilatation (HD) with corticosteroid injection for AC after breast cancer surgery. METHODS: Twenty-three prospective patients with AC after breast cancer surgery (BC group) and 44 retrospective patients with idiopathic AC without breast cancer (CON group) underwent HD with corticosteroid injection and home exercise training. We compared their biomechanical characteristics (capsular capacity, maximal pressure, and capsular stiffness). In the BC group, the passive range of motion (ROM) of the affected shoulder and a questionnaire (Shoulder Pain and Disability Index [SPADI]) were evaluated at baseline and 2 and 4 weeks after treatment. RESULTS: The BC group showed higher biomechanical characteristics (maximal pressure and capsular stiffness) than did the CON group. The mean maximal pressure and capsular stiffness were 519.67±120.90 mmHg and 19.69±10.58 mmHg/mL in the BC group and 424.78±104.42 mmHg and 11.55±7.77 mmHg/mL in the CON group (p=0.002 and p=0.001, respectively). And, the BC group showed significant improvements in all ROMs (abduction, flexion, and external rotation) and the SPADI pain and disability sub-scores following the treatment. CONCLUSION: The glenohumeral joint capsular stiffness was greater in the patients with AC after breast cancer surgery than in those with idiopathic AC. HD with corticosteroid injection was effective in treating AC after breast cancer surgery.
RESUMO
PURPOSE: Although hematopoietic stem cell transplantation (HSCT) is a curative treatment for hematologic malignancies, HSCT survivors often experience declined physical function and quality of life (QoL). However, the physical function and QoL changes in acute post-transplant patients remain unclear. This study aimed to investigate the impact of HSCT on physical function. METHOD: This retrospective control study included 107 HSCT patients. Physical function was evaluated weekly from admission to discharge using the de Morton Mobility Index (DEMMI). Impaired physical function was defined as a baseline raw ordinal DEMMI score of < 17 and a decrease of ≥ 2 points. We collected the Visual Analog Scale (VAS), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and Zung Self-rating Depression Scale (SDS) at enrollment and discharge. RESULTS: Based on the DEMMI scores, 41 patients (38.3%) showed impaired physical function. A notable decrease in the DEMMI score was found in the first week after HSCT. In the EORTC QLQ-C30, physical function differed between the groups at admission and discharge. The good physical function group showed better cognitive function and social function. For the SDS, the impaired physical function group showed significantly higher depression at discharge. CONCLUSION: A third of the patients showed physical impairment during the acute transplant period. Patients with low physical function suffered more from depression and lower QoL. Evaluating patients' pre-transplant physical function and early detection is needed as impaired physical function mainly occurs at 1 week post-transplant.

Dynamic changes in adipose tissue blood flow (ATBF) with nutritional status play a role in the regulation of metabolic and endocrine functions. Activation of the sympathetic nervous system via ß-adrenergic receptors (ß-AR) contributes to the control of postprandial enhancement of ATBF. Herein, we sought to identify the role of each ß-AR subtype in the regulation of ATBF in mice. We monitored the changes in visceral epididymal ATBF (VAT BF), induced by local infusion of dobutamine, salbutamol, and CL316,243 (a selective ß1-, ß2-, and ß3-AR agonist, respectively) into VAT of lean CD-1 mice and global adipose triglyceride lipase (ATGL) knockout (KO) mice, using laser Doppler flowmetry. Administration of CL316,243, known to promote lipolysis in adipocytes, significantly increased VAT BF of CD-1 mice to a greater extent compared to that of the vehicle, whereas administration of dobutamine or salbutamol did not produce significant differences in VAT BF. The increase in VAT BF induced by ß3-AR stimulation disappeared in ATGL KO mice as opposed to their wild-type (WT) littermates, implying a role of ATGL-mediated lipolysis in the regulation of VAT BF. Different vascular reactivities occurred despite no significant differences in vessel density and adiposity between the groups. Additionally, the expression levels of the angiogenesis-related genes were significantly higher in VAT of ATGL KO mice than in that of WT, implicating an association of ATBF responsiveness with angiogenic activity in VAT. Our findings suggest a potential role of ß3-AR signaling in the regulation of VAT BF via ATGL-mediated lipolysis in mice.
RESUMO
PURPOSE: Sentinel lymph node biopsy (SLNB) has become a standard axillary staging surgery for early breast cancer, and the proportion of patients requiring axillary lymph node dissection (ALND) is decreasing. We aimed to evaluate the association between the number of sentinel lymph nodes (SLNs) retrieved and the risk of lymphedema of the ipsilateral arm. METHODS: Prospectively collected medical records of 910 patients were reviewed. Lymphedema was defined as a difference in circumference > 2 cm compared to the contralateral arm and/or having clinical records of lymphedema treatment in the rehabilitation clinic. RESULTS: Together with an objective and subjective assessment of lymphedema, 36 patients (6.1%) had lymphedema in the SLNB group and 85 patients (27.0%) had lymphedema in the ALND group (p < 0.001). In a multivariate analysis of the whole cohort, risk factors significantly associated risk with the development of lymphedema were body mass index, mastectomy (vs. breast-conserving surgery), ALND, and radiation therapy. In logistic regression models in the SLNB group only, there was no correlation between the number of retrieved SLNs and the incidence of lymphedema. In addition, in the Pearson correlation analysis, no correlation was observed between the number of retrieved SLNs and the difference in circumference between the ipsilateral and contralateral upper extremities (correlation coefficients = 0.067, p =0.111). CONCLUSION: The risk of lymphedema in breast cancer surgery and adjuvant treatments is multifactorial. The number of retrieved lymph nodes during sentinel biopsy was not associated with the incidence of lymphedema.
RESUMO
BACKGROUND/AIM: Physical function is known to decrease after hematopoietic stem cell transplantation (HSCT), with the most substantial impairment noted at 90 days post-transplantation. Little is known about the natural course of physical function during the acute post-transplant period preciously. The aim of the study was to monitor the changes in physical function through serial evaluations of the physical function, and identify the effect of physical function on QoL during the acute post-transplant period. PATIENTS AND METHODS: This prospective cohort study included 41 patients admitted for planned autologous or allogeneic HSCT. Physical impairment was evaluated with decrease in the de Morton Mobility Index (DEMMI) every week and defined as a DEMMI score of more than 2 points after HSCT. The outcome variables for QoL included visual analogue scale (VAS), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), and Zung Self-rating Depression Scale (SDS) at enrollment and discharge. RESULTS: Based on DEMMI scores, 24.40% of all HSCT patients showed physical impairment, for whom the DEMMI score showed an overall decrease during hospitalization with significant differences in scores at 1, 2, and 3 weeks after HSCT, between 1 week before and 3 weeks after HSCT, and between 1 and 3 weeks after HSCT. There was no significant difference of VAS between admission and discharge between the groups. Each functional subscale of EORTC QLQ-C30 differed significantly between the groups, with lower scores in the physical impairment group. There was only a significant difference in SDS at discharge between the groups. QoL pre-transplantation can be a predictive factor for physical impairment during the acute post-transplant period, which can be detected in the early period after HSCT. CONCLUSION: Patients during acute post-transplant period had physical impairment and QoL of pre-transplantation was considered a predictive factor for physical impairment. The physical impairment can be detected in the early period after HSCT. Therefore, monitoring of standardized functional outcome measures is important to prevent physical impairment following HSCT.

PURPOSE: To investigate the relationship between physical function and quality of life in multiple myeloma patients. METHODS: In this retrospective cross-sectional study, data from patients with multiple myeloma (N = 63), who were referred to the department of Rehabilitation Medicine from October 2017 to May 2018, were reviewed. Patients were excluded based on the following criteria: acute illness, unstable medical conditions, impaired cognition or communication, refusal, or inability to perform the assessment. Physical function was evaluated with the Mini-Balance Evaluation Systems Test (Mini-BESTest), and the European Organization for Research and Treatment of Cancer questionnaires QLQ-C30 and QLQ-MY20 were used for the evaluation of quality of life. To evaluate fatigue and psychotic status, the Fatigue Severity Scale and Beck Depression Inventory were used. Patients were divided into two groups ("good-function group" and "poor-function group"), based on previously studied normative values of the Mini-BESTest. Clinical data was reviewed to interrogate the contributing factors of physical function. RESULTS: Positive correlations were observed between Mini-BESTest scores and all domains of the QLQ-C30. The Mini-BESTest score was lower in patients with lower serum hemoglobin (r = 0.396, p = 0.001) and albumin levels (r = 0.440, p < 0.001), severe disease-related symptoms (r = - 0.39, p = 0.02), and depression (r = - 0.538, p < 0.001). Further, the poor-function group showed lower hemoglobin (p = 0.024) and albumin levels (p = 0.004). CONCLUSION: In patients with multiple myeloma, physical function had a significant relationship with quality of life. Low hemoglobin and albumin levels, severe disease- or treatment-related symptoms, and depression were related to decreased physical function, and thus consequentially exert an effect on quality of life in multiple myeloma patients.

The goal of this study is to compare the risk of lower extremity lymphedema (LEL) between pelvic external beam radiation therapy (EBRT) and vaginal brachytherapy, and to identify risk factors for LEL in gynecologic cancer patients treated with adjuvant radiation therapy (RT) after radical surgery. A total of 263 stage I-III gynecologic cancer patients who underwent adjuvant RT were retrospectively reviewed. One-to-one case-matched analysis was conducted with propensity scores generated from patient, tumor, and treatment characteristics. Using the risk factors found in this study, high- and low-risk groups were identified. With a median follow-up of 36.0 months, 35 of 263 (13.3%) patients developed LEL. In multivariate analysis, laparoscopic surgery (HR 2.548; p = 0.024), harvesting more than 30 pelvic lymph nodes (HR 2.246; p = 0.028), and para-aortic lymph node dissection (PALND, HR 2.305; p = 0.014) were identified as independent risk factors for LEL. After propensity score matching, the LEL incidence of the brachytherapy group was significantly lower than the EBRT group (p = 0.025). In conclusion, high-risk patients with risk factors such as laparoscopic surgery, harvesting more than 30 pelvic lymph nodes, PALND, and adjuvant pelvic EBRT require closer observation for LEL.
RESUMO
BACKGROUND: Breast cancer-related lymphedema (BCRL) of the upper extremities often follows breast cancer treatment. Although complex decongestive therapy (CDT) is currently the standard treatment for BCRL, stellate ganglion block (SGB) has also been reported to be effective. OBJECTIVES: This study aimed to determine the effectiveness of SGB in the treatment of BCRL, and to assess the impact of the treatment on the quality of life (QoL) compared to CDT. STUDY DESIGN: A randomized controlled trial. SETTING: A single academic hospital, outpatient setting. METHODS: A total of 38 patients with BCRL were recruited. Patients were randomly divided into 2 groups. Patients enrolled in the CDT group underwent 10 sessions of CDT for 2 weeks, whereas patients in the SGB group received 3 consecutive SGBs every 2 weeks. Changes in circumference, volume, and bioimpedance in the upper extremity were measured at baseline and 2 weeks after treatment and compared between the 2 groups. EuroQol-5 dimensions (EQ-5D) and EuroQol visual analog scale (EQ VAS) for QoL and subjective improvement were monitored. RESULTS: In both groups, side-to-side difference of circumference after the treatment was decreased significantly from baseline (P < 0.05), and side-to-side difference of volume was reduced significantly in the SGB group (P < 0.05). No statistically significant difference was noted in the treatment effect between the 2 groups. Results of the EQ-5D, EQ VAS, and questionnaires regarding subjective symptoms administered at baseline and 2 weeks after each intervention revealed no statistically significant difference in the treatment effects between CDT and SGB. LIMITATIONS: Further long-term follow-up studies with a greater number of patients that include analysis according to the severity and duration of symptoms are needed. CONCLUSIONS: The results of this study suggest that SGB is an effective treatment for BCRL and may be considered as an alternative to CDT. KEY WORDS: Stellate ganglion block, complex decongestive therapy, breast cancer, lymphedema, breast cancer-related lymphedema, quality of life, bioimpedance, secondary lymphedema.

OBJECTIVES: Lymphedema is a chronic disease that occurs frequently after breast cancer treatment. For the treatment of lymphedema, surgical approach such as vascularized lymph node transfer and super-microscopic lymphovenous anastomosis surgery is well established. Complex decongestive therapy (CDT) and sympathetic ganglion block (SGB) are two non-surgical therapeutic options. This study aimed to evaluate the effectiveness of lymphoscintigraphy in guiding the selection of the optimal non-surgical treatment in lymphedema. METHODS: A total of 81 lymphedema patients who underwent lymphoscintigraphy and were treated with CDT or SGB were retrospectively evaluated. The parameters for the lymphoscintigraphic findings included the extent of dermal backflow (small extent/large extent groups), the level of lymphatic flow (trunk flow pattern/upper arm-restricted pattern/forearm-restricted pattern groups), and the visualization of lymph nodes (visualized/non-visualized groups). The change in the circumferential difference between the two sides of the body at the upper arm and forearm was used as the clinical outcome variable. Paired comparison and group comparison analysis were conducted. RESULTS: Of 81 patients, 41 received CDT and 40 received SGB. There were no significant differences in demographic data between the CDT and SGB groups. Both CDT and SGB had a significant therapeutic effect. Upper arm edema was more significantly reduced after SGB than after CDT in the small extent group (P = 0.004), the forearm-restricted pattern group (P = 0.002), and the non-visualized group (P = 0.018). In the other groups, SGB and CDT showed comparable therapeutic effects without statistical differences. CONCLUSION: SGB was found to have a better therapeutic effect in the lymphedema patients with specific lymphoscintigraphic findings compared with CDT. Lymphoscintigraphy may be helpful in selecting the appropriate approach to lymphedema treatment. Further well-designed prospective studies are warranted to validate the findings of this study.

OBJECTIVE: To investigate the effect of a rehabilitation program in terms of De Morton Mobility Index (DEMMI) score, in hematologic cancer patients after chemotherapy. METHODS: Hematologic cancer patients admitted for chemotherapy were reviewed. They received a rehabilitation program during their hospital stay. DEMMI score measurement was performed, before and after rehabilitation. Demographics, diagnosis, chemotherapy information, rehabilitation program duration, mortality, body mass index (BMI), and laboratory test results were collected. For analysis, patients were classified according to diagnosis (multiple myeloma, leukemia, and others), mortality, and additional chemotherapy. RESULTS: There was statistically significant improvement in DEMMI score of 10.1 points (95% confidence interval, 5.9-14.3) after rehabilitation. It was more evident in the multiple myeloma group, and they revealed less mortality. When patients were divided according to mortality, survivors received the program earlier, and in a shorter period than in mortality cases. Although survivors revealed higher initial DEMMI score, improvement after rehabilitation did not differ significantly. CONCLUSION: In hematologic cancer patients, rehabilitation program was effective for recovery from deconditioning, revealing significant increase in DEMMI score. Multiple myeloma patients may be good candidates for rehabilitation. Rehabilitation could be sustained during chemotherapy and for high-risk patients.
RESUMO
Park, JH, Seo, KS, and Lee, S-U. Effect of superimposed electromyostimulation on back extensor strengthening: a pilot study. J Strength Cond Res 30(9): 2470-2475, 2016-Electromyostimulation (EMS) superimposed on voluntary contraction (VC) can increase muscle strength. However, no study has examined the effect of superimposing EMS on back extensor strengthening. The purpose of this study was to determine the effect of superimposed EMS on back extensor strengthening in healthy adults. Twenty healthy men, 20-29 years of age, without low-back pain were recruited. In the EMS group, electrodes were attached to bilateral L2 and L4 paraspinal muscles. Stimulation intensity was set for maximally tolerable intensity. With VC, EMS was superimposed for 10 seconds followed by a 20-second rest period. The same protocol was used in the sham stimulation (SS) group, except that the stimulation intensity was set at the lowest intensity (5 mA). All subjects performed back extension exercise using a Swiss ball, with 10 repetitions per set, 2 sets each day, 5 times a week for 2 weeks. The primary outcome measure was the change in isokinetic strength of the back extensor using an isokinetic dynamometer. Additionally, endurance was measured using the Sorensen test. After 2 weeks of back extension exercise, the peak torque and endurance increased significantly in both groups (p ≤ 0.05). Effect size between the EMS group and the SS group was medium in strength and endurance. However, there was no statistically significant difference between 2 groups. In conclusion, 2 weeks of back extensor strengthening exercise was effective for strength and endurance. Superimposing EMS on back extensor strengthening exercise could provide an additional effect on increasing strength.

PURPOSE: The purpose of this study was to assess clinical practice and barriers associated with cancer rehabilitation from the perspective of Korean physiatrists. MATERIALS AND METHODS: All active members of the Korean Academy of Rehabilitation Medicine were invited to complete an online survey developed after focus group discussions. RESULTS: A total of 97 physiatrists (72 males and 25 females) in Korea completed the survey. Of these, 77% reported familiarity with the term 'cancer survivors.' More than 50% of respondents reported that they provided rehabilitation services for patients with breast cancer (61.9%), brain tumors (64.9%), and spinal tumors (63.9%), whereas 86.6% of respondents reported that they had never or rarely provided rehabilitation programs for patients with gynecological, colorectal, or prostate cancer. Physiatrists who received referrals from a well-organized cooperative referral system reported providing services such as exercise programs for patients with gynecological cancer (odds ratio [OR], 2.16; p=0.044) as well as education regarding lymphedema (OR, 1.81; p=0.047) and neuropathic pain (OR, 1.96; p=0.026). CONCLUSION: Although most of the physiatrists surveyed believed that they should contribute to the management of cancer patients, they considered themselves ill equipped to provide appropriate rehabilitation services. This lack of understanding of the effectiveness of rehabilitation services for cancer patients and absence of a cooperative referral system are the major barriers to providing rehabilitation services to cancer survivors in Korea.
RESUMO
OBJECTIVE: To determine the effects of SGB in BCRL patients and the efficacy of corticosteroids in SGB. STUDY DESIGN: A double-blinded, randomized, controlled trial. SETTING: A single academic hospital, outpatient setting. METHODS: In total, 32 patients with BCRL were recruited. Patients were divided randomly into 3 groups (Group A: 0.5% bupivacaine 5 mL, n = 12; Group B: 0.5% bupivacaine 4.5 mL + 20 mg of triamcinolone 0.5 mL, n = 10; and Group C: 0.5% bupivacaine 4 mL + 40 mg of triamcinolone 1 mL, n = 10). All patients received 3 consecutive SGBs, every 2 weeks. The primary outcomes were changes in forearm and upper arm circumference. Circumference was measured at baseline, 2 weeks (before the second injection), 4 weeks (before the third injection), and 8 weeks (one month follow-up after 3 consecutive SGBs). Moreover, subjective data were collected using EORTC C-30 at baseline and 8 weeks. RESULTS: After 3 consecutive SGBs, forearm and upper arm circumferences were decreased significantly from baseline in all groups (P < 0.05/3). The upper arm circumference of group C was reduced significantly more than that of group A (P < 0.05/3). The subjective data by EORTC-C30 at baseline and one month after 3 consecutive SGBs revealed no statistically significant difference. LIMITATIONS: Relatively few patients were enrolled. We did not compare SGB with any other BCRL treatment, such as complex decongestive therapy. CONCLUSIONS: This study suggests that SGB may be an effective treatment for BCRL. Furthermore, it appears that corticosteroids could have an additive effect in SGB.
