RESUMEN

Pelvic lymph node dissection (PLND) is commonly performed alongside radical prostatectomy. Its primary objective is to determine the lymphatic staging of prostate tumors by removing lymph nodes involved in lymphatic drainage. This aids in guiding subsequent treatment and removing metastatic foci, potentially offering significant therapeutic benefits. Despite varying recommendations from clinical practice guidelines across countries, the actual implementation of PLND is inconsistent, partly due to debates over its therapeutic value. While high-quality evidence supporting the superiority of PLND in oncological outcomes is lacking, its role in increasing surgical time and risk of complications is well-recognized. Despite these concerns, PLND remains the gold standard for lymph node staging in prostate cancer, providing invaluable staging information unattainable by other techniques. This article reviews PLND's scope, guideline perspectives, implementation status, oncologic and non-oncologic outcomes, alternatives, and future research needs.

RESUMEN

OBJECTIVES: To study the safety and efficacy of a personalised indocyanine-guided pelvic lymph node dissection (PLND) against extended PLND (ePLND) during radical prostatectomy (RP). PATIENTS AND METHODS: Patients who were candidates for RP and lymphadenectomy, with intermediate- or high-risk prostate cancer (PCa) according to the National Comprehensive Cancer Network guidelines, were enrolled in this randomised clinical trial. Randomisation was made 1:1 to indocyanine green (ICG)-PLND (only ICG-stained LNs) or ePLND (obturator fossa, external, internal, and common iliac and presacral LNs). The primary endpoint was the complication rate within 3 months after RP. Secondary endpoints included: rate of major complications (Clavien-Dindo Grade III-IV), time to drainage removal, length of stay, percentage of patients classified as pN1, number of LNs removed, number of metastatic LNs, rate of patients with undetectable prostate-specific antigen (PSA), biochemical recurrence (BCR)-free survival, and rate of patients with androgen-deprivation therapy at 24 months. RESULTS: A total of 108 patients were included with a median follow-up of 16 months. In all, 54 were randomised to ICG-PLND and 54 to ePLND. The postoperative complication rate was higher in the ePLND (70%) vs the ICG-PLND group (32%) (P < 0.001). Differences between major complications in both groups were not statically significant (P = 0.7). The pN1 detection rate was higher in the ICG-PLND group (28%) vs the ePLND group (22%); however, this difference was not statistically significant (P = 0.7). The rate of undetectable PSA at 12 months was 83% in the ICG-PLND vs 76% in the ePLND group, which was not statistically significant. Additionally, there were no statistically significant differences in BCR-free survival between groups at the end of the analysis. CONCLUSIONS: Personalised ICG-guided PLND is a promising technique to stage patients with intermediate- and high-risk PCa properly. It has shown a lower complication rate than ePLND with similar oncological outcomes at short-term follow-up.

RESUMEN

Secondary lymphedema is caused by lymphatic insufficiency (lymphatic drainage failure) following lymph node dissection during the surgical treatment or radiation therapy of breast or pelvic cancer. The clinical problems associated with lymphedema are reduced quality of life in terms of appearance and function, as well as the development of skin ulcers, recurrent pain, and infection. Currently, countermeasures against lymphedema are mainly physical therapy such as lymphatic massage, elastic stockings, and skin care, and there is no effective and fundamental treatment with a highly recommended grade. Therefore, there is a need for the development of a fundamental novel treatment for intractable lymphedema. Therapeutic lymphangiogenesis, which has been attracting attention in recent years, is a treatment concept that reconstructs the fragmented lymphatic network to recover lymphatic vessel function and is revolutionary to be a fundamental cure. This review focuses on the translational research of therapeutic lymphangiogenesis for lymphedema and outlines the current status and prospects in the development of therapeutic applications.

RESUMEN

PURPOSE: Breast cancer-related lymphedema (BCRL) represents a lifelong risk for breast cancer survivors and once acquired becomes a lifelong burden. This review summarizes current BCRL prevention and treatment strategies. FINDINGS: Risk factors for BCRL have been extensively studied and their identification has affected breast cancer treatment practice, with sentinel lymph node removal now standard of care for patients with early stage breast cancer without sentinel lymph node metastases. Early surveillance and timely management aim to reduce BCRL incidence and progression, and are further facilitated by patient education, which many breast cancer survivors report not having adequately received. Surgical approaches to BCRL prevention include axillary reverse mapping, lymphatic microsurgical preventative healing (LYMPHA) and Simplified LYMPHA (SLYMPHA). Complete decongestive therapy (CDT) remains the standard of care for patients with BCRL. Among CDT components, facilitating manual lymphatic drainage (MLD) using indocyanine green fluorescence lymphography has been proposed. Intermittent pneumatic compression, nonpneumatic active compression devices, and low-level laser therapy appear promising in lymphedema management. Reconstructive microsurgical techniques such as lymphovenous anastomosis and vascular lymph node transfer are growing surgical considerations for patients as well as liposuction-based procedures for addressing fatty fibrosis formation from chronic lymphedema. Long-term self-management adherence remains problematic, and lack of diagnosis and measurement consensus precludes a comparison of outcomes. Currently, no pharmacological approaches have proven successful. CONCLUSION: Progress in prevention and treatment of BCRL continues, requiring advances in early diagnosis, patient education, expert consensus and novel treatments designed for lymphatic rehabilitation following insults.

RESUMEN

The aim of the study was to explore the application value of manual lymphatic drainage combined with vacuum sealing drainage in axillary web syndrome (AWS) after breast cancer surgery. From 1 April 2020 to 1 June 2020, a total of 102 patients with AWS after axillary lymph node biopsy or axillary lymph node dissection in our hospital were included in this prospective study. According to the random number table method, all patients were divided into the study group (n = 51) and the control group (n = 51). The study group received the treatment of manual lymphatic drainage combined with vacuum sealing drainage, and the control group received health education and the treatment of functional training. The efficacy observation indicators included duration time to the disappearance of relevant clinical symptoms, degree of pain, angle of abduction of the affected limb, degree of upper limb disability function and quality of life. The duration time to the disappearance of cord-like nodules and tightness in the study group was both significantly shorter than that in the control group (both P < .05). In the time point of 1 and 3 months after the intervention, compared with that in the control group, the study group had a significantly lighter degree of pain, a better degree of upper limb disability function and higher quality of life (all P < .05). Manual lymphatic drainage combined with vacuum sealing drainage can shorten the disappearance time of relevant clinical symptoms, relieve the degree of pain, improve the upper limb disability function and improve the quality of life in patients with AWS.

RESUMEN

PURPOSE: Axillary lymph node dissection and radiotherapy have been associated with pain, physical symptoms, and decreased functional abilities in the upper extremity. This study aimed to evaluate the potential effects of the proprioceptive neuromuscular facilitation (PNF) technique on muscle strength, pain and functionality in this patient group in comparison with progressive resistance training (PRT). METHODS: The study was conducted with a randomized clinical trial design. Sixty-six women were included in the study and randomly divided into three groups: the PNF group (n = 22), the PRT group (n = 22), and the control group (n = 22). The participants were evaluated at the baseline and after eight weeks of treatment. Outcome measures were determined as pain (the Visual Analog Scale), upper extremity strength (isokinetic dynamometer), functionality (the Disabilities of the Arm, Shoulder and Hand questionnaire), and perception of change (the Global Rating of Change Scale). TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT05288036. RESULTS: The results showed statistically significant changes in both treatment groups in terms of shoulder flexors/extensors, abductor/adductors, internal/external rotators strength/power/endurance measurement, pain, and functionality (p < 0.05). Concerning functionality and perception of change, the PNF group had a statistically significantly higher improvement compared to the remaining two groups (p < 0.05). CONCLUSION: PNF is an effective technique in increasing upper extremity muscle strength, reducing pain during rest and activity, and improving functionality in patients receiving breast cancer treatment.

RESUMEN

BACKGROUND: The need for axillary dissection (AD) is declining, but it is still essential for many patients with nodal involvement who risk developing breast-cancer-related lymphedema (BCRL) with lifelong consequences. Previous nonrandomized studies found axillary reverse mapping and selective axillary dissection (ARM-SAD) a safe and feasible way to preserve the arm's lymphatic drainage. METHODS: The present two-arm prospective randomized clinical trial was held at a single comprehensive cancer center to ascertain whether ARM-SAD can reduce the risk of BCRL, compared with standard AD, in patients with node-positive breast cancer. Whatever the type of breast surgery or adjuvant treatments planned, 130 patients with nodal involvement met our inclusion criteria: 65 were randomized for AD and 65 for ARM-SAD. Twelve months after surgery, a physiatrist assessed patients for BCRL and calculated the excess volume of the operated arm. Lymphoscintigraphy was used to assess drainage impairment. Self-reports of any impairment were also recorded. RESULTS: The difference in the incidence of BCRL between the two groups was 21% (95% CI, 3-37; p = .03). A significantly lower rate of BCRL after ARM-SAD was confirmed by a multimodal analysis that included the physiatrist's findings, excess arm volume, and lymphoscintigraphic findings, but this was not matched by a significant difference in patients' self-reports. CONCLUSIONS: Our findings encourage a change of surgical approach when AD is still warranted. ARM-SAD may be an alternative to standard AD to reduce the treatment-related morbidity.

RESUMEN

Axillary web syndrome (AWS) is defined as a visible and palpable network of cords in the skin of the axillary cavity that are tensed by shoulder abduction following surgery for breast cancer, causing significant functional limits of the ipsilateral upper limb (UL) and pain. The purpose of this narrative review is to discuss rehabilitation approaches for greater efficacy with respect to pain and novel suggestions. AWS is a frequent complication of axillary lymphadenectomy that necessitates a thorough follow-up in the medium to long term. Physiotherapy is effective in the treatment of functional limb deficits, the management of pain, and the treatment of upper limb disability. The best management approach involves the use of soft tissue techniques to slow the natural course of the syndrome, in association with therapeutic exercises for functional recovery and muscle strengthening. AWS is linked secondary lymphedema, requiring integration with manual lymphatic drainage. The physiotherapy management of AWS is currently fragmented, and insufficient information is available on the nature of the disease. Thus, randomized and controlled studies that compare rehabilitation approaches in AWS are desirable, including the possibility of using mesotherapy in the treatment of axillary and upper limb pain.

RESUMEN

INTRODUCTION: Disturbance in the lymphatic drainage during D2 dissection is associated with significant morbidity. We aimed to assess the effect of fibrin glue on the reduction of postoperative lymphatic leakage. METHODS: Prospective double-blinded randomized clinical trial with forty patients in each study arm was conducted. All patients diagnosed, staged, and became a candidate for D2 dissection based on NCCN 2019 guideline for gastric cancer. The intervention group received 1 cc of IFABOND® applied to the surgical bed. RESULTS: The difference between study groups regarding age, gender, tumor stage was insignificant. (All p-values > 0.05). The median daily drainage volume was 120 ml with the first and the third interquartile being 75 and 210 ml, respectively for the intervention group. The control group had median, the first, and the third interquartile of 350, 290, and 420 ml. The difference between daily drainage volumes was statistically significant (p-value < 0.001). The length of hospital stay was significantly different between the two groups. Notably, the intervention group was discharged sooner (median of 7 Vs 9 days, p-value: 0.001). CONCLUSION: This study showed the possible role of fibrin glue in reducing postoperative lymphatic leakage after gastrectomy and D2 dissection. Registration trial number: IRCT20200710048071N1, 2020.08.16.

RESUMEN

PURPOSE: Breast lymphoedema is a largely unrecognised survivorship issue for women following breast cancer treatment. While a few objective methods have previously been applied to assess breast lymphoedema, none are capable of imaging breast lymphatics or identifying lymphatic morphological changes indicative of breast lymphoedema. The purpose of this study was to determine if indocyanine green (ICG) lymphography, a validated assessment technique in breast cancer-related lymphoedema), can visualise breast lymphatics and identify breast lymphoedema. Additionally, ICG lymphography was utilised to investigate lymphatic drainage pathways of the affected breast following breast-conserving therapy. METHODS: Twenty female participants (10 breast lymphoedema and 10 healthy controls) were recruited for this pilot study. All underwent a medical history, physical breast assessment, tissue dielectric constant measures of breast water content, and ICG lymphography. RESULTS: ICG lymphography identified lymphatic morphological changes in all breast lymphoedema participants (dermal backflow patterns = 10, collateral lymphatic drainage = 9) and none in the control group. The dominant lymphatic drainage pathway to the ipsilateral axilla was observed in all control participants but in only four breast lymphoedema participants. Collateral drainage pathways in the breast lymphoedema group were to: parasternal (6/10); contralateral axilla (4/10); intercostal (3/10); and clavicular (2/10) regions. CONCLUSION: These findings suggest ICG lymphography, through the identification of morphological lymphatic changes, is a potential qualitative objective assessment technique for breast lymphoedema. Furthermore, in this group of breast lymphoedema patients it identified changes to the normal drainage pathway of the breast. Understanding these changes will have implications for clinical management.

RESUMEN

BACKGROUND: There is a lack of evidence in support of any prophylactic measure to prevent secondary lower extremity lymphedema after radical hysterectomy among patients with cervical cancer. This study aimed to determine the effectiveness of modified complex decongestive physiotherapy in reducing the risk of secondary lower extremity lymphedema after radical surgery. METHODS: A randomized single-blind clinical trial was conducted in 120 patients with cervical cancer who underwent laparoscopic radical hysterectomy with pelvic lymphadenectomy between January 2016 and April 2017 in the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China. Participants were randomly assigned to a modified complex decongestive physiotherapy intervention group (n=60) or control group (n=60). The intervention group received a modified complex decongestive physiotherapy program, which included manual lymph drainage, compression hosiery, regular exercise, and health education. The control group only received a health education program. The main outcome was the incidence of secondary lower extremity lymphedema. RESULTS: A total of 117 patients with cervical cancer completed a 1-year follow-up. Twenty-eight (23.9%) patients developed secondary lower extremity lymphedema (20 (34.5%) patients in the control group and 8 (13.6%) in the intervention group). The incidence of secondary lower extremity lymphedema was significantly higher in the control group than in the intervention group (p=0.008; OR 0.30 (95% CI 0.12 to 0.75). The median percentage of excess volume was significantly less in the intervention group (2.1%, IQR 0.5-3.4%) than in the control group (2.96%, IQR 1.1-4.98%); (p=0.042). The mean (SD) onset time of lymphedema was 8 (2.00) months vs 4.6 (2.82) months in the intervention and control groups, respectively (p=0.004). CONCLUSIONS: This randomized trial showed that modified complex decongestive physiotherapy is effective for preventing lower extremity lymphedema in patients with cervical cancer after laparoscopic radical hysterectomy with pelvic lymphadenectomy.

RESUMEN

Besides histologic features, the presence of nodal metastasis is the most crucial prognostic factor for recurrence and survival for patients with gynecologic cancer. Conventionally, lymphadenectomy has been performed routinely to assess lymphatic metastasis. However, lymphadenectomy may be unnecessary in early-stage gynecologic cancer, because the percentage of patients with lymph node involvement is very low. The recent use of sentinel lymph node mapping has provided high feasibility, safety, and accuracy in the assessment of nodal metastasis. The National Comprehensive Cancer Network Clinical Practice Guidelines have incorporated the sentinel lymph node for nodal evaluation in vulvar, endometrial, and cervical cancers.

RESUMEN

OBJECTIVES: To describe the available techniques to prevent and treat complications related with surgery involving lymphatic nodes and drainage: lymphorrea, lymphocele and lymphedema. METHODS: Bibliographic review and personal experience communication of different image-assisted techniques in the prevention and management of lymphatic related complications. RESULTS: We describe the conventional lymphography with ethiodized oil contrast (lipiodol) by lymphatic catheterization and intranodal percutaneous puncture used in diagnostics and interventional radiology; the gammagraphic lymphography with radioactive isotopes for diagnostic use; and the utilization of colorants/dyes (patent blue, V-blue, methylene blue, indocyanine green) for diagnostic and therapeutic procedures. CONCLUSIONS: Lipiodol lymphography offers well-defined radiologic images and it is useful in interventional radiology procedures. It has the inconvenience of lymphatics catheterization and is not available for surgical dynamic identification of lymphatics. Isotopic techniques are used for diagnostics and sentinel-node procedures. Colorants and dyes have several advantages: no need for catheterization, not expensive technology, price, availability, easy management. It allows the dynamic identification of lymphatics for surgical resolution of lymph-related complications.


OBJETIVOS: Describir los diferentes métodos de prevención y resolución de complicaciones y secuelas derivadas de actos quirúrgicos relacionados con el drenaje linfático ­ linforrea, linfocele y linfedema.MÉTODOS: Revisión de la literatura y comunicación de la experiencia personal de alternativas diagnósticas y terapéuticas con asistencia guiada de imagen. RESULTADOS: Describimos la linfografía mediante cateterización linfática e intranodal con aceite etiodizado (lipiodol) con fines diagnósticos y terapéuticos; la linfografía gammagráfica mediante el uso de isótopos radioactivos con fines diagnósticos; y el uso de colorantes -azul de isosulfan, azul patente, azul de metileno y verde de indocianina- con finalidad diagnóstica y terapeútica. CONCLUSIONES: La linfografía con lipiodol ofrece imágenes bien definidas y es útil en maniobras de radiología intervencionista. Presenta el inconveniente de precisar cateterismo linfático y la imposibilidad de su uso dinámico intraoperatorio. Las técnicas isotópicas son utilizadas con finalidad diagnóstica y en técnicas de biopsia de ganglio centinela. El uso de colorantes ofrece la ventaja de no precisar cateterismo linfático ni de tecnología compleja, precio, disponibilidad, facilidad de uso y de tratarse de una técnica dinámica que permite la identificación intraoperatoria para la resolución de las complicaciones mencionadas.

RESUMEN

Chylous ascites may complicate the postoperative course of abdominal surgery mainly due to the iatrogenic disruption of the lymphatic channels during extensive retroperitoneal dissection. Sparse data are available regarding treatment; however, in many cases a recommended first-line treatment approach is by way of enteral feeding, consisting of a formula high in medium-chain triglycerides (MCTs) together with a complete total parenteral nutrition teamed with somatostatin (or an equivalent). Nonetheless, the ligation of chylous fistulae, together with the application of Fibrin glue, as well as the creation of peritoneal-venous shunts have also been documented. The aims of this study are to document incidence of postoperative chylous ascites following resection of abdominal peripheral neuroblastic tumors, evaluate efficacy of the management of chylous ascites, and investigate the main risk factors. A survey was carried out over a span of six years, from March 2010 to March 2016 at Giannina Gaslini Children's Hospital involving seventy-seven children with resections of peripheral neuroblastic tumors. Incidence rate of postoperative chylous ascites following a normal diet was 9% (n=7). Treatment using total parenteral nutrition with octreotide resulted in a complete recovery from chylous ascites within a 20 day period without recurrence. Length of operative time, nephrectomy, and the extension of lymphadenectomy were all significantly associated with a higher incidence of postoperative chylous ascites (p<0.05) which also lengthened hospital stay (p<0.05) and possibly delayed beginning adjuvant chemotherapy.

RESUMEN

BACKGROUND: Lymphatic leakage is one of the severe complications after lymphadenectomy. However, efficient treatment it still unclear. MATERIALS AND METHODS: We employed inguinal lymphadenectomy and saphenous lymphatic vessel excision to establish a inguinal lymphatic leakage rabbit model. Rabbits with bilateral lymphatic leakage were divided in two groups, which were subject to negative pressure wound therapy (NPWT) on right sides and dressing change on left sides, respectively. Following 7-11 d of treatment, skin thickness and drainage volume were measured. Western blot and RT-PCR were used for analyzing the VEGF-C level. Tissues of wound were dissected and subject to anti-LYVE-1 immunohistochemical for lymphatic average positive staining area percentage and the ratio of lymphatic lumen area evaluation. RESULTS: Our lymphatic leakage model showed significant lymph stasis, delayed wound healing, and skin swelling and was confirmed by methylene blue instillation. Using this rabbit model, we found that NPWT could largely promote wound healing and resolution of skin edema. Compared with the dressing change group, the thickness of the dermis layer in the NPWT group was significantly reduced. Western blot and RT-PCR analysis showed a decrease of VEGF-C in the NPWT group. The immunohistochemical result of the NPWT group did not show a significant change in lymphatic average positive staining area percentage, whereas the ratio of lymphatic lumen area was significantly decreased, suggesting that NPWT treatment can significantly compress the dilated lymphatic vessels. CONCLUSIONS: We successfully established the first clinically relevant lymphatic leakage model in rabbits. NPWT can be an effective treatment for lymphatic leakage via reducing edema and lymphatic stasis by compressing dilated lymph vessels and promoting lymphatic drainage.

RESUMEN

BACKGROUND AND OBJECTIVES: This study is aimed to investigate the possibility of preoperative oral oil administration in displaying the chylous tubes and preventing chylous leakage in laparoscopic para-aortic lymphadenectomy. MATERIALS AND METHODS: In this retrospective nonrandomized study, of the 30 patients with gynecological malignancies who had indications for laparoscopic para-aortic lymphadenectomy up to renal vessels, 15 were administered preoperative oral oil (oil a administration) (control group) at our hospital between September 2017 and June 2018. The chylous tube displaying rates, incidences of chylous leakage, and other perioperative data of the two groups were compared. RESULTS: Successful display of chylous tubes was observed in 93.3% (14/15) patients in the oil administration group. The chylous leakage was zero in the oil administration group, and 33.3% (5/15) in the control group. The postoperative drainage duration (4.1 ± 1.0 days vs 7.6 ± 1.4 days, P = 0.000), somatostatin application time (0 day vs 5.9 ± 0.8 days), and postoperative hospital stay (6.0 ± 2.3 days vs 9.1 ± 2.1 days, P = 0.001) were significantly shorter in the oil administration group. The total cost is lower in the oil administration group (4972.52 ± 80.54 dollars vs 6260.80 ± 484.47 dollars, P = 0.000). CONCLUSIONS: Preoperative oil administration is a feasible and effective method to display the chylous tubes and to prevent the chylous leakage in para-aortic lymphadenectomy.

RESUMEN

BACKGROUND: Several studies and a meta-analysis showed that fibrin sealant patches reduced lymphatic drainage after various lymphadenectomy procedures. Our goal was to investigate the impact of these patches on drainage after axillary dissection for breast cancer. METHODS: In a phase III superiority trial, we randomized patients undergoing breast-conserving surgery at 14 Swiss sites to receive versus not receive three large TachoSil® patches in the dissected axilla. Axillary drains were inserted in all patients. Patients and investigators assessing outcomes were blinded to group assignment. The primary endpoint was total volume of drainage. RESULTS: Between March 2015 and December 2016, 142 patients were randomized (72 with TachoSil® and 70 without). Mean total volume of drainage in the control group was 703 ml [95% confidence interval (CI) 512-895 ml]. Application of TachoSil® did not significantly reduce the total volume of axillary drainage [mean difference (MD) -110 ml, 95% CI -316 to 94, p = 0.30]. A total of eight secondary endpoints related to drainage, morbidity, and quality of life were not improved by use of TachoSil®. The mean total cost per patient did not differ significantly between the groups [34,253 Swiss Francs (95% CI 32,625-35,880) with TachoSil® and 33,365 Swiss Francs (95% CI 31,771-34,961) without, p = 0.584]. In the TachoSil® group, length of stay was longer (MD 1 day, 95% CI 0.3-1.7, p = 0.009), and improvement of pain was faster, although the latter difference was not significant [2 days (95% CI 1-4) vs. 5.5 days (95% CI 2-11); p = 0.2]. CONCLUSIONS: TachoSil® reduced drainage after axillary dissection for breast cancer neither significantly nor relevantly.
