Characterizing Normal Upper Extremity Lymphatic Flow with 99mTc In-House Dextran: A Retrospective Study. Diagnostics (Basel) 2024; 14:1960. [PMID: 39272744 PMCID: PMC11393990 DOI: 10.3390/diagnostics14171960] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2024] [Revised: 08/14/2024] [Accepted: 08/23/2024] [Indexed: 09/15/2024] Open
Abstract
Lymphoscintigraphy evaluates the lymphatic system using radiocolloid compounds like 99mTc-sulfur colloid and 99mTc-nanocolloid, which vary in particle size and distribution timing. A local in-house Dextran kit (15-40 nm) was developed in 2005 and began clinical use in 2008 to localize sentinel lymph nodes; diagnose lymphedema; and detect lymphatic leakage. The normal drainage pattern remains unexplored. We retrospectively analyzed 84 upper extremity lymphoscintigraphies from 2008 to 2021. 99mTc in-house Dextran was intradermally injected into both hands, followed by whole-body imaging at specified intervals (≤15 min; 16-30 min; 31-45 min; 46-60 min), with some receiving delayed imaging. Visual and quantitative analyses recorded axillary and forearm lymph nodes and liver, kidney, and urinary bladder activity. Results showed 92% (77/84) upper extremity lymphatic tract visualization within 45 min. Axillary node detection rates increased from 46% (≤15 min) to 86% (46-60 min). Delayed imaging further revealed nodes. Epitrochlear or brachial node visualization was rare (4%, 3/84). Hepatic, renal, and urinary bladder activity was noted in 54%, 71%, and 93% at 1 h, respectively. The axillary node uptake ratio was minimal (<2.5% of injection site activity; median 0.33%). This study characterizes normal upper extremity lymphatic drainage using 99mTc in-house Dextran, offering insights into its clinical application.

Abstract
Background: Breast cancer-related lymphedema (BCRL) remains a significant postcancer treatment challenge with no definitive cure. Recent supermicrosurgical treatments, such as lymphovenous anastomosis (LVA), have shown promise but lack established objective indicators for outcome evaluation. We investigated the utility of Technetium-99m (Tc-99m) lymphoscintigraphy, an imaging technique providing objective information on lymphatic fluid flow, for assessing LVA surgical outcomes. Methods and Results: A retrospective cohort analysis of patients undergoing LVA for BCRL was conducted. Lymphoscintigraphy images pre- and 1-year postsurgery were compared to determine changes in lymphatic fluid flow of 18 patients based on newly defined parameters "uptake ratio" and "washout rates." Statistically significant reduction in the uptake ratio was observed in the forearm at 30 and 60 minutes postinjection phases. In addition, the forearm showed higher washout rate, indicating an improved lymphatic function in the forearm. Conclusion: Tc-99m lymphoscintigraphy can provide valuable objective data for evaluating LVA surgical outcomes in BCRL patients. However, site-specific differences in outcomes highlight the need for individualized surgical planning. Further large-scale studies are necessary to validate these preliminary findings and develop a standardized approach for LVA assessment.

Abstract
Lymphedema is a progressive chronic condition affecting approximately 250 million people worldwide, a number that is currently underestimated. In Western countries, the most common form of lymphedema of the extremities is cancer-related and less radical surgical intervention is the main option to prevent it. Standardized protocols in the areas of diagnosis, staging and treatment are strongly required to address this issue. The aim of this study is to review the main diagnostic methods, comparing new emerging procedures to lymphoscintigraphy, considered as the golden standard to date. The roles of Magnetic Resonance Lymphangiography (MRL) or indocyanine green ICG lymphography are particularly reviewed in order to evaluate diagnostic accuracy, potential associations with lymphoscintigraphy, and future directions guided by AI protocols. The use of imaging to treat lymphedema has benefited from new techniques in the area of lymphatic vessels anatomy; these perspectives have become of value in many clinical scenarios to prevent cancer-related lymphedema.

Abstract
Background: The purpose of this study was to measure the effects of lymphoscintigraphically guided manual lymphatic drainage (LG-MLD) and to compare it with standardized manual lymphatic drainage (St-MLD). Materials and Methods: Fifty-two patients with lymphedema of the upper limb who underwent lymphoscintigraphy were randomly allocated into two groups. Following the phase of physical activity, the control group underwent two phases of St-MLD as the experimental group underwent a first phase of St-MLD followed by a second phase of LG-MLD. Areas of interest were then selected [in particular, dermal backflow (DBF) and axillary lymph nodes (LN)], radioactive activities were quantified for each of these areas. Results: If a first phase of St-MLD increased the LN activity by 28% on average, the findings indicated that for the second phase of DLM, LG-MLD was 19% more efficient than St-MLD in increasing LN activity. If a period of rest does not influence the lymph charge of DBF areas, physical activity leads to an average activity increase of 17%, whereas LG-MLD and St-MLD lead to an activity decrease of 11%. Conclusions: For patients with lymphedema, the findings indicate that MLD can increase the lymphatic flow toward the lymphatic nodes by 28% on average and can decrease the charge in the areas of DBF by 11% on average. Moreover, lymphoscintigraphy can be an important therapeutic tool because LG-MLD significantly increases lymphatic flow by 19% more than St-MLD. Concerning the areas of DBF, the LG-MLD and St-MLD decrease the charge in these areas with the same intensity.

Risk factors of unilateral breast cancer-related lymphedema: an updated systematic review and meta-analysis of 84 cohort studies. Support Care Cancer 2022; 31:18. [PMID: 36513801 DOI: 10.1007/s00520-022-07508-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Accepted: 12/02/2022] [Indexed: 12/15/2022]
Abstract
PURPOSE To review and update the incidence and risk factors for breast cancer-related lymphedema based on cohort studies. METHODS The study was guided by the Joanna Briggs Institute methodology and the Cochrane handbook for systematic reviews. PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, CNKI, SinoMed, and Wan Fang Database were searched from inception to November 15, 2021. Cohort studies reported adjusted risk factors were selected. PRISMA guideline was followed. Study quality were evaluated using the Newcastle-Ottawa scale. Random-effects models were adopted. The robustness of pooled estimates was validated by meta-regression and subgroup analysis. Lymphedema incidence and adjusted risk factors in the multivariable analyses with hazard / odds ratios and 95% CIs were recorded. RESULTS Eighty-four cohort studies involving 58,358 breast cancer patients were included. The pooled incidence of lymphedema was 21.9% (95% CI, 19.8-24.0%). Fourteen factors were identified including ethnicity (black vs. white), higher body mass index, higher weight increase, hypertension, higher cancer stage (III vs. I-II), larger tumor size, mastectomy (vs. breast conservation surgery), axillary lymph nodes dissection, more lymph nodes dissected, higher level of lymph nodes dissection, chemotherapy, radiotherapy, surgery complications, and higher relative volume increase postoperatively. Additionally, breast reconstruction surgery, and adequate finance were found to play a protective role. However, other variables such as age, number of positive lymph nodes, and exercise were not correlated with risk of lymphedema. CONCLUSION Treatment-related factors still leading the development of breast cancer-related lymphedema. Other factors such as postoperative weight increase and finance status also play a part. Our findings suggest the need to shift the focus from treatment-related factors to modifiable psycho-social-behavioral factors.

Abstract
BACKGROUND We investigated whether preoperative lymphoscintigraphy could predict the treatment response of unilateral lymphovenous anastomosis (LVA) in patients with lower extremity lymphedema. MATERIALS AND METHODS A total of 17 patients undergoing lymphoscintigraphy subsequent to LVA was included. As qualitative lymphoscintigraphic indicators, ilioinguinal lymph node uptake, main lymphatic vessel, collateral vessel, and four types of dermal backflow patterns (absent; distal only; proximal only; whole lower limb) were evaluated. Lymph node uptake ratio, extremity uptake ratio, and injection site clearance ratio were obtained as quantitative lymphoscintigraphic indicators at 1 and 2-h after injection. To evaluate therapy response, the volume difference ratio of the whole lower limb at 3 months (early response) and 1 year (late response) was measured. Volume difference ratios (continuous variable and binary variable with a cut-off value of zero) were compared according to the lymphoscintigraphic variables. RESULTS The group with whole lower limb dermal backflow had a greater volume change than the other groups (p = 0.047). The group with dermal backflow in the whole lower limb OR only in the distal part had a higher rate of volume reduction than the group with dermal backflow only in the proximal part OR absent (p = 0.050). The 2-h extremity uptake ratio was the only indicator that positively correlated with early and late volume difference ratio (p = 0.016, p = 0.001). The rate of volume decrease at 1 year was high in patients with high 2-h extremity uptake ratio (p = 0.027). As the amount of dermal backflow increases, the postoperative therapeutic effect increases (p = 0.040). CONCLUSIONS Preoperative lymphoscintigraphy is useful to predict both early and late therapy response in patients with lower extremity lymphedema undergoing LVA. Both dermal backflow pattern and extremity uptake ratio may be predictive lymphoscintigraphic indicators.

Abstract
Objective To compare the treatment effects, satisfaction with the treatment, and performance improvement following bandage treatment using the spiral method and spica method for breast cancer-related lymphedema (BCRL). Methods A prospective study with 46 patients with BCRL was conducted. All patients were divided into either the spiral or spica group for non-elastic bandage therapy and received the same treatment for 2 weeks, apart from the group-specific bandaging method used. For both groups, the Quality of Life Instrument score before treatment, changes in the volume of lymphedema limb and the Disability of the Arm, Shoulder, and Hand (DASH) score before and after treatment, and treatment satisfaction after treatment were compared. The Student t-test was used to compare the parameters between the two different bandage methods. Results With respect to the treatment outcomes, total volume reduction and proximal part volume reduction after treatment were 98.0±158.3 mL and 56.0±65.4 mL in the spiral method group and 199.0±125.1 mL and 106.1±82.2 mL in the spica method group, respectively. Therefore, the spica method group showed a significantly better improvement (p<0.05). The DASH score changes after treatment showed that the spiral group score increased by 3.8±5.4 and the spica group score increased by 7.7±6.1; thus, a significantly better improvement was noted in the spica group (p<0.05). Conclusion The spica method indicated better volume reduction and DASH score improvement than the spiral method. Therefore, the spica method may be more effective for treating patients with BCRL.

Abstract
No method has yet been approved for detecting lymphedema fibrosis before its progression. This study assessed the feasibility of computed tomography-based estimation of fibrosis. This observational, cross-sectional study included patients with lymphedema affecting one limb. Three types (maximum, mean, minimum) of computed tomography reticulation indexes were digitally calculated from trans-axial images using absorptive values, and the computed tomography reticulation indexes compared with clinical scales and measurements. Of 326 patients evaluated by at least one of lymphoscintigraphy, bio-electrical impedance, and computed tomography, 24 were evaluated by all three. The mean number of computed tomography scans in these patients was 109. Sixteen patients had breast cancer, seven had gynecologic cancers, and one had primary lymphedema. Mean computed tomography reticulation index (r = 0.52, p < 0.01) and maximal computed tomography reticulation index (r = 0.45, p < 0.05) were significantly associated with time from initial limb swelling to computed tomography. Mean computed tomography reticulation index (r = 0.86, p < 0.01), minimal computed tomography reticulation index (r = 0.79, p < 0.01), and maximal computed tomography reticulation index (r = 0.68, p < 0.01) were significantly associated with International Society of Lymphedema substage. Minimal computed tomography reticulation index correlated with 1-kHz-based bio-electrical impedance ratio (r = -0.46, p < 0.05) and with standardized proximal limb circumference difference ratio (r = 0.45, p < 0.05) of both limbs. Maximal computed tomography reticulation index had a sensitivity of 0.78, specificity of 0.60, and areas under the curve of 0.66 in detecting lymphoscintigraphic stage IV. The algorithm utilizing three-dimensional computed tomography images of epifascial fibrosis may be used as a marker for lymphedema duration, limb swelling, International Society of Lymphedema substage, and interstitial lymphatic fluids of lymphedema. The current approach shows promise in providing an additional method to assist in characterizing and monitoring lymphedema patients.

Abstract
Background Most lymphatic imaging examinations of the lower limb require intradermal or subcutaneous injection of tracer material into the foot to demonstrate the lymphatic vessels; however, no standard protocol exists, and single or multiple injections are applied at different sites. Purpose To determine the three-dimensional relationships between each lymphatic group of the lower limb and corresponding regional lymph nodes. Materials and Methods A total of 130 lower limbs (55 from men and 75 from women) from 83 fresh human cadavers were studied. Lymphatic vessels were first visualized by using indocyanine green fluorescent lymphography with 19 injection sites in the foot, classified into four distinct lymphatic groups (anteromedial, anterolateral, posteromedial, and posterolateral); dilute oil-based contrast material was then injected. Next, specimens were scanned with CT and three-dimensional images were analyzed. Results The anteromedial and anterolateral lymphatic groups of the lower-leg lymphatic vessels were independent of each other and connected to different regional lymph nodes in the inguinal region. The posteromedial group and the anteromedial group in the lower leg drained to the same inguinal lymph nodes. Only the posterolateral group of lymphatic vessels in the lower leg drained to the popliteal lymph nodes. Leg lymphatic drainage pathways were independent of genital pathways. Conclusion Standard injection sites at the web spaces between the toes did not help visualize some lymph nodes of the lower leg. Additional injection sites in the medial, lateral, and posterior aspect of the foot would be better for evaluating the whole lymphatic pathways and regional lymph nodes and for improving understanding of leg lymphedema. © RSNA, 2019 Online supplemental material is available for this article.

[PMID: 30857863 DOI: 10.1016/j.asjsur.2019.02.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Revised: 01/25/2019] [Accepted: 02/14/2019] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Lymphedema of the upper extremity is a common disease in breast cancer patients following breast cancer operation accompanied by lymphadenectomy. However, clinically, there is a discrepancy between the extent of axillary lymph node dissection (ALND) and the severity of lymphedema. Therefore, we investigated the relationship between the severity of lymphedema following breast cancer operation, including ALND, and axillary lymph node findings on lymphoscintigraphy. METHODS Eighty-two patients with lymphedema following breast cancer operation with ALND (82 women; mean age 55.57 ± 9.39, range 36-65) were retrospectively recruited. Lymphoscintigraphy was conducted after an average of 5.44 ± 2.01 months following operation. Percentage differences in the circumference of the upper extremities between affected and unaffected sides were used as a severity index. RESULTS Percentage differences in the circumference of the upper extremities in a positive and negative group in lymphoscintigraphy were 3.42 ± 2.47% and 12.87 ± 10.23% in the mid-arm respectively (p < 0.05), and 3.36 ± 3.80% and 12.83 ± 10.00% in the mid-forearm respectively (p < 0.05). However, the extent of lymph node dissection and the difference in the circumference of mid-arm and mid-forearm volume did not have a statistically significant relationship. CONCLUSION Lymph node activity in the proximal upper extremity is not related to the extent of ALND. The existence of a bypass connection and remainder function of a lymph node is crucial for the severity of lymphedema.
