ABSTRACT
PURPOSE: This research aimed to clarify the metastatic patterns of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma and to investigate appropriate strategies for lymph node dissection. METHODS: Patients with thoracic esophageal squamous cell carcinoma receiving esophagectomy from December 2020 to April 2024 were retrospectively analyzed. Risk factors for subcarinal, right and left recurrent laryngeal nerve lymph nodes metastasis were determined by chi-square test and multivariate logistic regression analysis. We visualized the metastasis rates of these specific lymph nodes based on the different clinicopathological characteristics. Correlation between subcarinal, right and left recurrent laryngeal lymph nodes metastasis and postoperative complications were also analyzed. RESULTS: A total of 503 thoracic esophageal squamous carcinoma patients who underwent esophagectomy were enrolled. The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes were 10.3%, 10.3%, and 10.9%, respectively. The lymphovascular invasion status and tumor location were the significant predictors for subcarinal and right recurrent laryngeal nerve lymph nodes metastasis, respectively (P < 0.001 and P = 0.013). For left recurrent laryngeal nerve lymph node metastasis, younger age (P = 0.020) and presence of lymphovascular invasion (P = 0.009) were significant risk factors. Additionally, pulmonary infection is the most frequent postoperative complication in patients with dissection of subcarinal, right and left recurrent laryngeal lymph nodes. There was no significant difference in the incidence of anastomotic leakage (P = 0.872), pulmonary infection (P = 0.139), chylothorax (P = 0.702), and hoarseness (P = 0.179) between the subcarinal lymph node dissection cohort and the reservation cohort. The incidence of hoarseness significantly increased in both right (P = 0.042) and left (P = 0.010) recurrent laryngeal nerve lymph nodes dissection cohorts compared by the reservation cohorts, with incidence rates of 5.9% and 6.7%, respectively. CONCLUSIONS: The metastasis rates of subcarinal, right and left recurrent laryngeal nerve lymph nodes in thoracic esophageal squamous cell carcinoma were all over 10%. The dissection of subcarinal lymph nodes does not increase postoperative complications risk, while recurrent laryngeal nerve lymph nodes dissection significantly increases the incidence of hoarseness. Thus, lymph node dissection of subcarinal lymph nodes should be conducted routinely, while recurrent laryngeal nerve lymph nodes dissection may be selectively performed in specific patients.

Breast cancer related lymphedema (BCRL) affects many breast cancer survivors and drastically affects their quality of life. There are several surveillance methods for BCRL that are critical at early detection. Prevention of BCRL involves knowledge of alternatives to aggressive axillary surgery, avoidance of axillary surgery, and de-escalation of axillary surgery. There are also techniques to better delineate the anatomy in the axilla to avoid taking nodes that drain the upper extremity. A multidisciplinary approach with medical oncology and radiation oncology can also help avoid unnecessary surgery or radiation that can together strongly increase the risk of BCRL.

PURPOSE: Routine use of abdominal drain or prolonged antibiotic prophylaxis is no longer part of current clinical practice in colorectal surgery. Nevertheless, in patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (ICA), it may reduce perioperative abdominal contamination. Furthermore, in cancer patients, prolonged surgery with extensive dissection such as central vascular ligation and complete mesocolon excision with D3 lymphadenectomy (altogether radical right colectomy RRC) is called responsible for affecting postoperative ileus. The aim was to evaluate postoperative resumption of gastrointestinal functions in patients undergoing right hemicolectomy for cancer with ICA and standard D2 dissection or RRC, with or without abdominal drain and prolonged antibiotic prophylaxis. METHODS: Monocentric factorial parallel arm randomized pilot trial including all consecutive patients undergoing laparoscopic right hemicolectomy and ICA for cancer, in 20 months. Patients were randomized on a 1:1:1 ratio to receive abdominal drain, prolonged antibiotic prophylaxis or neither (I level), and 1:1 to receive RRC or D2 colectomy (II level). Patients were not blinded. The primary aim was the resumption of gastrointestinal functions (time to first gas and stool, time to tolerated fluids and food). Secondary aims were length of stay and complications' rate. CLINICALTRIALS: gov no. NCT04977882. RESULTS: Fifty-seven patients were screened; according to sample size, 36 were randomized, 12 for each arm for postoperative management, and 18 for each arm according to surgical techniques. A difference in time to solid diet favored the group without drain or antibiotic independently from standard or RRC. Furthermore, when patients were divided with respect to surgical technique and into matched cohorts, no differences were seen for primary and secondary outcomes. CONCLUSION: Abdominal drainage and prolonged antibiotic prophylaxis in patients undergoing right hemicolectomy for cancer with ICA seem to negatively affect the resumption of a solid diet after laparoscopic right hemicolectomy with ICA for cancer. RRC does not seem to influence gastrointestinal function recovery.

BACKGROUND: Surgery for oesophageal squamous cell carcinoma involves dissecting lymph nodes along the recurrent laryngeal nerve. This is technically challenging and injury to the recurrent laryngeal nerve may lead to vocal cord palsy, which increases the risk of pulmonary complications. The aim of this study was to compare the efficacy and safety of robot-assisted oesophagectomy (RAO) versus video-assisted thoracoscopic oesophagectomy (VAO) for dissection of lymph nodes along the left RLN. METHODS: Patients with oesophageal squamous cell carcinoma who were scheduled for minimally invasive McKeown oesophagectomy were allocated randomly to RAO or VAO, stratified by centre. The primary endpoint was the success rate of left recurrent laryngeal nerve lymph node dissection. Success was defined as the removal of at least one lymph node without causing nerve damage lasting longer than 6 months. Secondary endpoints were perioperative and oncological outcomes. RESULTS: From June 2018 to March 2022, 212 patients from 3 centres in Asia were randomized, and 203 were included in the analysis (RAO group 103; VAO group 100). Successful left recurrent laryngeal nerve lymph node dissection was achieved in 88.3% of the RAO group and 69% of the VAO group (P < 0.001). The rate of removal of at least one lymph node according to pathology was 94.2% for the RAO and 86% for the VAO group (P = 0.051). At 1 week after surgery, the RAO group had a lower incidence of left recurrent laryngeal nerve palsy than the VAO group (20.4 versus 34%; P = 0.029); permanent recurrent laryngeal nerve palsy rates at 6 months were 5.8 and 20% respectively (P = 0.003). More mediastinal lymph nodes were dissected in the RAO group (median 16 (i.q.r. 12-22) versus 14 (10-20); P = 0.035). Postoperative complication rates were comparable between the two groups and there were no in-hospital deaths. CONCLUSION: In patients with oesophageal squamous cell carcinoma, RAO leads to more successful left recurrent laryngeal nerve lymph node dissection than VAO, including a lower rate of short- and long-term recurrent laryngeal nerve injury.

Oesophageal cancer often requires complex surgery. Recently, minimally invasive techniques like robot- and video-assisted surgery have emerged to improve outcomes. This study compared robot- and video-assisted surgery for oesophageal cancer, focusing on removing lymph nodes near a critical nerve. Patients with a specific oesophageal cancer type were assigned randomly to robot- or video-assisted surgery at three Asian hospitals. Robot-assisted surgery had a higher success rate in removing lymph nodes near the important nerve without permanent damage. It also had shorter operating times, more lymph nodes removed, and faster drain removal after surgery. In summary, for oesophageal cancer surgery, the robotic approach may provide better lymph node removal and less nerve injury than video-assisted techniques.

A 76-year-old woman was diagnosed with invasive bladder cancer and underwent cystectomy, bilateral external iliac, internal iliac and obturator lymph node dissection, and bilateral cutaneous ureterostomy. Pathological findings showed no lymph node metastasis ; however, the patient had lower abdominal pain and fever from the 14th postoperative day, and computed tomography (CT) revealed fluid retention in the pelvis. Retrograde pyelography showed no leakage from the urinary tract, and a drain was placed after percutaneous puncture of the pelvic cavity. There was copious drainage fluid and its nature and composition suggested lymphorrhea. Ultrasound-guided intranodal lymphangiography revealed contrast material leakage from the bilateral lymph node dissection sites. After lymphangiography, drainage from the drain decreased. Despite the drainage being minimal yet persistent, sclerotherapy was performed, the drain was removed and the patient was discharged. After discharge, there was leakage from the site of urethral extraction, and CT revealed recurrent lymph leakage. The patient was readmitted, and a second lymphangiography was performed. The leakage from the site of urethral extraction gradually decreased, and the patient was discharged on the 59th postoperative day. CT after discharge confirmed that the lymphorrhea had shrunk in size, and there has been no recurrence since then. Lymphangiography is a promising treatment option for lymphorrhea after pelvic surgery.

BACKGROUND: Cervical cancer is the fourth most frequently diagnosed cancer and the fourth leading cause of cancer death in women, The standard treatment recommendation for women with early cervical cancer is radical hysterectomy with pelvic lymph node dissection, however, articles published in recent years have concluded that the treatment outcome of laparoscopic surgery for cervical cancer is inferior to that of open surgery. Thus, we choose a surgically new approach; the laparoscopic cervical cancer surgery in the open state is compared with the traditional open cervical cancer surgery, and we hope that patients can still have a good tumor outcome and survival outcome. This trial will investigate the effectiveness of laparoscopic cervical cancer surgery in the open-state treatment of early-stage cervical cancer. METHOD AND DESIGN: This will be an open-label, 2-armed, randomized, phase-III single-center trial of comparing laparoscopic radical hysterectomy based on open state with abdominal radical hysterectomy in patients with early-stage cervical cancer. A total of 740 participants will be randomly assigned into 2 treatment arms in a 1:1 ratio. Clinical, laboratory, ultrasound, and radiology data will be collected at baseline, and then at the study assessments and procedures performed at baseline and 1 week, 6 weeks, and 3 months, and follow-up visits begin at 3 months following surgery and continue every 3 months thereafter for the first 2 years and every 6 months until year 4.5. The primary aim is the rate of disease-free survival at 4.5 years. The secondary aims include treatment-related morbidity, costs and cost-effectiveness, patterns of recurrence, quality of life, pelvic floor function, and overall survival. CONCLUSIONS: This prospective trial aims to show the equivalence of the laparoscopic cervical cancer surgery in the open state versus the transabdominal radical hysterectomy approach for patients with early-stage cervical cancer following a 2-phase protocol.

Lower extremity lymphedema (LEL) is a common complication following surgical staging of endometrial cancer. LEL is a chronic condition associated with significant impact on patient morbidity and quality of life (QoL). This review aimed to report the current evidence in the literature on secondary LEL after surgical staging for endometrial cancer, focusing on the incidence based on different approaches to lymph node staging, diagnosis, risk factors, and the impact on QoL. Due to the absence of a standardized agreement regarding the methodology for evaluating LEL, the documented frequency of occurrence fluctuates across different studies, ranging from 0% to 50%. Systematic pelvic lymphadenectomy appears to be the primary determinant associated with the emergence of LEL, whereas the implementation of sentinel lymph node biopsy has notably diminished the occurrence of this lymphatic complication after endometrial cancer staging. LEL is strongly associated with decreased QoL, lower limb function, and negative body image, and has a detrimental impact on cancer-related distress reported by survivors. Standardization of lymphedema assessment is needed, along with cross-cultural adaptation of subjective outcome measures for self-reported LEL. The advent of sentinel lymph node mapping represents the ideal approach for accurate nodal assessment with less short- and long-term morbidity. Further research is needed to definitively assess the prevalence and risk factors of LEL and to identify strategies to improve limb function and QoL in cancer survivors with this chronic condition.

BACKGROUND: Elderly gastric cancer patients (EGCPs) require treatment according to not just the stage of their cancer, but also to their general condition and organ function, and rather than full treatment, the appropriate amount of treatment is necessary. METHODS: A total of 425 patients who underwent gastrectomy for primary gastric cancer in our institution between April 2013 and March 2020 were classified by age into two groups: elderly patients (EP, age ≥ 80 years, n = 89); and younger patients (YP, age < 80 years, n = 336). The preoperative, intraoperative, and postoperative conditions of the two groups were then compared. Propensity score matching (PSM) was performed, and factors affecting complications and survival outcomes were examined in detail. In addition, the necessary treatment strategy for EGCPs in the preoperative, intraoperative, and postoperative periods was investigated. RESULTS: Of the preoperative factors, American Society of Anesthesiologists physical status (ASA-PS) was significantly higher, and respiratory function was significantly lower in the EP group than in the YP group, and the prognostic nutritional index (PNI) also tended to be lower. Of the intraoperative factors, there was no difference in the level of lymph node dissection. However, the EP group had significantly higher rates of postoperative pneumonia and anastomotic leakage. Of the postoperative factors, on simple comparison, postoperative long-term outcomes of the EP group were significantly worse (63.8% vs. 85.4%, p < 0.001), but there was no significant difference in disease-specific survival (DSS), and the DSS survival curves after PSM were almost identical, indicating that the survival rate in the EP group was decreased by death from other disease. Though the survival rate of laparoscopic surgery was significantly better than that of open surgery in the YP group, there was a significantly lower rate of postoperative complications in the EP group after PSM. CONCLUSIONS: In EGCPs, one needs to be aware of short-term complications such as pneumonia and anastomotic leakage due to respiratory dysfunction and malnutrition that are present before surgery. Furthermore, to suppress deaths from other diseases that reduce postoperative survival rates, prevention of postoperative complications (particularly pneumonia) through minimally invasive surgery can be effective.

BACKGROUND: Inguinal lymph node dissection plays an important role in the management of melanoma, penile and vulval cancer. Inguinal lymph node dissection is associated with various intraoperative and postoperative complications with significant heterogeneity in classification and reporting. This lack of standardization challenges efforts to study and report inguinal lymph node dissection outcomes. The aim of this study was to devise a system to standardize the classification and reporting of inguinal lymph node dissection perioperative complications by creating a worldwide collaborative, the complications and adverse events in lymphadenectomy of the inguinal area (CALI) group. METHODS: A modified 3-round Delphi consensus approach surveyed a worldwide group of experts in inguinal lymph node dissection for melanoma, penile and vulval cancer. The group of experts included general surgeons, urologists and oncologists (gynaecological and surgical). The survey assessed expert agreement on inguinal lymph node dissection perioperative complications. Panel interrater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS: Forty-seven experienced consultants were enrolled: 26 (55.3%) urologists, 11 (23.4%) surgical oncologists, 6 (12.8%) general surgeons and 4 (8.5%) gynaecology oncologists. Based on their expertise, 31 (66%), 10 (21.3%) and 22 (46.8%) of the participants treat penile cancer, vulval cancer and melanoma using inguinal lymph node dissection respectively; 89.4% (42 of 47) agreed with the definitions and inclusion as part of the inguinal lymph node dissection intraoperative complication group, while 93.6% (44 of 47) agreed that postoperative complications should be subclassified into five macrocategories. Unanimous agreement (100%, 37 of 37) was achieved with the final standardized classification system for reporting inguinal lymph node dissection complications in melanoma, vulval cancer and penile cancer. CONCLUSION: The complications and adverse events in lymphadenectomy of the inguinal area classification system has been developed as a tool to standardize the assessment and reporting of complications during inguinal lymph node dissection for the treatment of melanoma, vulval and penile cancer.

BACKGROUND Massive chylous leakage represents a rare yet potentially life-threatening complication following neck dissection, and its occurrence is even less common in the context of endoscopic thyroid surgery. Chylous leakage poses significant clinical management challenges, encompassing prolonged hospitalization, nutritional deficiencies, electrolyte imbalances, and the potential for infection. It is imperative for surgeons to remain vigilant and proactive in recognizing and managing chylous leakage to mitigate its potential impact on patient outcomes. CASE REPORT A 37-year-old woman presented with a thyroid nodule, and subsequent fine-needle aspiration biopsy confirmed the diagnosis of papillary thyroid carcinoma. She then underwent endoscopic thyroidectomy with central lymph node dissection via a bilateral areola approach and experienced significant postoperative chylous leakage. Various conservative management strategies were used to treat the leak, including fasting, parenteral nutrition, maintenance of electrolyte balance, and continuous infusion of somatostatin. After failure of a series of conservative treatments, the patient underwent a reoperation to address the leak via the initial approach. After identification of the leak site, the residual end of the lymphatic vessel was clamped with a biological clamp, and no further chylous leakage was observed. The drainage was removed 4 days after the second operation, and the patient was discharged on the fifth day. During follow-up, no abnormalities were observed. CONCLUSIONS Managing significant chylous leakage poses a challenge for surgeons. This complication is rare following endoscopic thyroidectomy with central lymph node dissection, and there remains a lack of experience in effective prevention and treatment. We aim to raise awareness through our case report.

PURPOSE OF REVIEW: The most common surgical procedure associated with lymphedema formation is the regional lymphadenectomy. One of the advantages of sentinel node biopsy is the reduction of the risk of lymphedema formation. The purpose of this review is to collect and analyze the most relevant and recent evidence of the use of sentinel node biopsy and its implication on the development of postoperative lymphedema in gynecological cancer. RECENT FINDINGS: The current evidence of the use of sentinel node biopsy in cervical cancer to reduce lymphedema is heterogeneous and more data is needed to establish its role.Sentinel lymph node biopsy in endometrial cancer is a staging procedure with lower surgical complications, as well as lymphedema formation; while the results of prospective trials evaluating its impact on quality of life are still lacking.Sentinel lymph node biopsy in vulvar cancer minimizes the need for extensive dissection and reduces the incidence of complications associated with overharvesting of lymph nodes such as lymphedema without compromising oncological outcomes. SUMMARY: The prevalence of lymphedema in gynecological cancer varies based on the surgical treatment or additional therapies applied. Over the past years, one of the most important surgical modifications to decrease lymphedema formation has been implementation of sentinel lymph node technique mainly in vulvar cancer patients.

BACKGROUND: Lymphoedema is a chronic and progressive disease characterised by excessive accumulation of lymph in the interstitial compartment, leading to tissue swelling and fibroadipose deposition. Lymphangiogenesis is partly regulated by ketone body oxidation, and a ketogenic diet (KD) has shown therapeutic efficacy in a preclinical mouse tail lymphoedema model. Therefore, we aimed to investigate the potential therapeutic effect of a KD in patients with secondary lymphoedema. METHODS: Nine patients with unilateral stage 2 lymphoedema secondary to lymphadenectomy were included in this quasi-experimental exploratory study consisting of a short run-in phase to gradually induce ketosis, followed by a classic KD (CKD) and modified Atkins diet (MAD) phase during which patients consumed a CKD and MAD, respectively. Lymphatic function and oedema volume, the primary outcomes, were assessed at baseline and at the end of both the CKD and MAD phase. Secondary outcomes included health-related and lymphedema-specific quality of life (QoL). RESULTS: Seven out of nine patients completed the study protocol. Lymphatic function was improved upon consumption of both a CKD (dermal backflow score [mean ± SD]: 7.29 ± 2.98 vs. 10.86 ± 2.19 at baseline; p = 0.03) and MAD (6.71 ± 2.06; p = 0.02), whereas oedema volume did not decrease during the course of the study (excess limb volume [mean ± SD]: 20.13 ± 10.25% at end of CKD and 24.07 ± 17.77% at end of MAD vs. 20.79 ± 12.96% at baseline; p > 0.99 and p > 0.30, respectively). No changes were observed in health-related, nor lymphoedema-specific QoL at the end of CKD and MAD. CONCLUSIONS: The consumption of a KD improved lymphatic function and was associated with a clinically meaningful reduction in oedema volume in some patients (3/7 at end of CKD, 2/7 at end of MAD) with unilateral stage 2 secondary lymphoedema. These results highlight the potential of a KD to improve lymphatic function in patients with lymphoedema. However, further studies are required to substantiate our findings.

INTRODUCTION: Inguinal lymph nodes dissection (ILND) is recommended in patients presenting with high-risk penile (PC) or vulvar cancers (VC). Though, this surgical procedure is underused because of its anticipated morbidity. Minimally invasive approaches were proposed to minimize complications associated with open surgery. In this review, we analyze current available data exploring intra and perioperative outcomes of robot-assisted ILND (RAIL). EVIDENCE ACQUISITION: On April 9th, 2023, a literature search was conducted using the PubMed and Scopus databases. The search employed the combination of the following terms: ("robotic assisted" OR "robot-assisted" OR "robotic") AND ("inguinal lymph node dissection" OR "lymphadenectomy") AND ("penile cancer" OR "vulvar cancer"). Out of the 404 identified articles, 18 were used for the present scoping review and their results were reported according to the PRISMA statement. EVIDENCE SYNTHESIS: Data on 171 patients, ranging in age from 32 to 85 years, were obtained. Most of them (90.6%) harbored a penile squamous cell carcinoma and presented with no palpable nodes (85%). Operation time (OT) ranged between 45 and 300 min. Estimated blood loss varied from 10 to 300 mL. One single intra-operative complication was reported and one conversion to open was recorded. The lymph nodes (LNs) count spanned from 3 to 26 per groin, with 17 studies reporting a median yield >7 nodes. Hospital stay was 1-7 days, while the duration of drainage ranged from 4 to 72 days. Post-operative complications included lymphocele (22.2%; 0-100%), lymphedema (13.4%; 0-40%), cellulitis (11.1%; 0-25%), skin necrosis (8.7%; 0-15.4%). seroma (3.5%; 0-20%) and wound breakdown/wound infection (2.9%; 0-10%). Out of the included studies, 7 provided at least a 12-month follow-up, with recurrence-free rates ranging from 50% to 100% in patients affected by penile cancer and from 92% to 100% in vulvar cancer patients. CONCLUSIONS: The available evidence on RAIL for the treatment of PC and VC is limited. The approach appears to be safe and effective, as it provides an adequate lymph node yield while ensuring a minimally morbid postoperative course and a short hospital stay.

Introduction: We presented the key findings from Singapore's Changi General Hospital Breast Centre's lymphedema surveillance strategy that used patients' reported symptoms, standard arm circumference measurements and clinical assessment in the diagnosis of breast cancer-related lymphedema (BCRL). Our secondary aim was to highlight and discuss important elements of a surveillance strategy that can be implemented to track this outcome measure of breast cancer treatment for future research. Method: We conducted a cross-sectional study of 511 breast cancer patients to assess the prevalence of BCRL and its associated risk factors. We defined BCRL prevalence rates based on patients' self-reporting, objective arm circumference measure-ments and clinical diagnosis based on International Society of Lymphology (ISL) staging. Results: The median follow-up of patients was 88.8 months. The cumulative prevalence rate in the cohort was 30.9%. The cohort of BCRL patients were older (58.4 versus [vs] 54.9 years), had higher mean Body Mass Index (27.7 vs 25.2), higher proportion of mastectomy (77% vs 64.3%), axillary clearance, less likely breast reconstruction, higher-grade tumour, more lymph nodes excised, more advanced nodal disease, and had undergone adjuvant chemotherapy. However, clinically apparent BCRL was only 6.5% (33 out of 511 patients). The proportion of clinically significant BCRL in patients undergoing sentinel lymph node biopsy (SLNB) or axillary sampling was 1.7% compared to 9.9% in patients who had undergone axillary clearance. Majority of the BCRL were subclinical or mild in severity. Conclusion: Our study showed that our rates of BCRL were comparable to international rates and highlighted similar patient profiles who were at risk of developing the disease. Having a comprehensive lymphedema surveillance strategy is paramount in paving the way for future studies.

BACKGROUND: This phase II trial sought to be the first of its kind to estimate the success rate of endermology in reducing breast cancer-related lymphedema. PATIENTS AND METHODS: ELOCS is a French, monocentric, randomized, open-label phase II trial. Patients were randomized to receive the following over a 5-day treatment period: standard intensive decongestant treatment (IDT) (bandages and manual lymphatic drainage MLD) (group 1); IDT including bandages, MLD, and Cellu M6 (group 2); and IDT including bandages and Cellu M6 (Group 3). The main endpoint was the success rate in each group, (reduction of at least 30% in the excess volume). We estimated that endermology treatment (groups 2 and 3) would be of interest successes occurred in at least 21 out of 31 patients. RESULTS: A total of 93 patients were included (31 patients in each of the 3 groups). The median age was 64.5 years (IQR: [56.4-71.3]). Patients were treated with mastectomy (n = 35), axillary lymphadenectomy (n = 80), radiotherapy (n = 91), and chemotherapy (n = 68). The mean relative reduction in excess volume was 38% in group 1, 33% in group 2, and 34% in group 3. Success rate was 58.1% in group 1 (18/31, P = ,0237), 51.6% (16/31, P = ,5) in group 2, and 64.5% (20/31, P = ,075) in group 3. In the LPG groups (2 and 3), 10/62 (16%) patients found LPG painful and 9/62 (15%) patients considered it to be unpleasant. CONCLUSION: Even though the critical threshold of 21 successes was not met, this study was the first to validate a standardized and reproducible endermology protocol.

BACKGROUND: Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group. METHODS: A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines. RESULTS: Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001). CONCLUSION: The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

BACKGROUND AND OBJECTIVES: We evaluated the unmet breast cancer-related lymphedema (BCRL) treatment and education needs at New England's largest safety-net hospital serving a diverse population by assessing prevalence, risk factors, and treatment. METHODS: This was a retrospective cohort study examining breast cancer surgery patients from September 2016 to September 2021. The primary outcome was BCRL diagnosis. Secondary outcomes included BCRL risk factors, and physical and occupational therapy (PT/OT) referral frequency and completion. RESULTS: Of 639 patients, 17% of patients had documented BCRL, which was significantly associated with axillary lymph node dissection (ALND). There were no racial, insurance, breast radiation, or BMI category differences between patients with and without a BCRL diagnosis. Of those with BCRL, 58% received a PT/OT referral, and 56% completed their referral. There were no racial, insurance, or BMI category differences between those who received a PT/OT referral and those who did not. CONCLUSION: In our high-risk population, rates of documented BCRL were higher than expected, approaching rates of ALND, despite the majority undergoing sentinel lymph node biopsy (SLNB). PT/OT referral and completion rates were low, concerning for an unmet BCRL treatment and education need. No disparities in care delivery were seen, but a program that addresses treatment gaps and ensures accessible and patient-centered BCRL care is urgently needed.

BACKGROUND: Inguinal lymphadenectomy (ILND) has historically been associated with substantial morbidity. The objective of this study was to obtain contemporary ILND morbidity rates and to identify potentially preventable risk factors. METHODS: We carried out a retrospective review of medical records for all superficial, deep, and combination groin dissections performed at a single, high-volume academic centre between January 2007 and December 2020. We collected data points for patient, disease, and surgery characteristics, and cancer outcomes. The outcome of interest was any complication within 30 days of surgery. Complications included wound infection, wound necrosis or disruption, seroma, drainage procedure, hematoma, and lymphedema. We performed multivariate logistic regression using SAS version 9.4. RESULTS: We identified 139 patients having undergone 89 superficial, 12 deep, and 38 combined dissection types, respectively. Melanoma accounted for 84.9% of cases. Of these patients, 56.1% had an adverse postoperative event within 30 days. Increasing age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.01-1.07, p < 0.01) and number of positive lymph nodes harvested (OR 1.22, 95% CI 1.00-1.50, p = 0.05) were associated with more complications. Patients with deep dissection showed a lower likelihood of complications than those with superficial dissection (OR 0.15, 95% CI 0.03-0.84, p < 0.05). CONCLUSION: Complication rates after ILND remain high. We identified a number of risk factors, providing opportunities for better selection and prevention.
