Effect of manual lymphatic drainage combined with vacuum sealing drainage on axillary web syndrome caused by breast cancer surgery.

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.

Efficacy of proprioceptive neuromuscular facilitation in improving shoulder biomechanical parameters, functionality, and pain after axillary lymph node dissection for breast cancer: A randomized controlled study.

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.

Occurrence of breast-cancer-related lymphedema after reverse lymphatic mapping and selective axillary dissection versus standard surgical treatment of axilla: A two-arm randomized clinical trial.

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.

Randomised clinical trial of a manual therapy programme to reduce the evolution time of axillary web syndrome in women affected by breast cancer: study protocol.

INTRODUCTION: Breast cancer is the most common malignant tumour in women, with more than 2 million new cases annually worldwide. One of the most frequent and well-known surgical and post-actinic sequelae is post-mastectomy lymphoedema. The axillary web syndrome is another sequela that limits the functionality of the patient and delays the protocol time of administering cancer treatments; and in many cases, this sequela is misdiagnosed. This surgical sequela usually disappears spontaneously after the third month of appearance, but this implies a long period of discomfort and limitations for the patient, at the same time, it may delay the application of radiotherapy within the indicated protocol deadline (due to a need for body posture). METHODS AND ANALYSIS: With the present quasi-experimental study, we intend to show the application of physiotherapy and stretching from the beginning of the appearance of the axillary cord, in a controlled and scheduled way by the physiotherapist. It is possible to reduce the time in which the lymphatic thrombus is present and, therefore, recover functionality and mobility, reduce pain and be able to apply treatments within the established deadline. We intend to apply this therapy into the intervention group and compare thrombus evolution time with the control group. ETHICS AND DISSEMINATION: This trial has the approval of the Andalucía Ethics Committee (PEIBA code 1909-N1-21, reg. number 171.21). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT05115799).

Changes in the Pattern of Superficial Lymphatic Drainage of the Abdomen after Abdominoplasty.

BACKGROUND: The changes in the pattern of lymphatic drainage of the superficial abdominal wall after abdominoplasty are still unknown. These changes may increase the risk of numerous complications, including seroma formation. Depending on the alterations, the manual lymphatic drainage technique should be modified in postoperative patients. The aim of this study was to map the pattern of lymphatic drainage of the superficial infraumbilical abdominal wall after abdominoplasty. METHODS: Twenty women with indications for abdominoplasty were selected in the Plastic Surgery Division of the Federal University of São Paulo. Intradermal lymphoscintigraphy with dextran 500-99m-technetium was performed in 20 female patients in the preoperative phase and 1 and 6 months after abdominoplasty to evaluate superficial lymphatic drainage of the abdominal wall. RESULTS: Before surgery, all patients presented with abdominal lymphatic drainage toward the inguinal lymph nodes. One and 6 months after abdominoplasty, only 15 percent exhibited the same drainage pathway. Drainage toward the axillary lymph node chain occurred in 65 percent of the patients, 10 percent displayed a drainage pathway toward both the axillary and inguinal lymph nodes, and lymphatic drainage was indeterminate in 10 percent of the cases. CONCLUSIONS: A significant change in lymphatic drainage pathway occurred in the infraumbilical region after abdominoplasty. The axillary drainage path was predominant after the operation, in contrast to the inguinal path observed in the preoperative period. However, 35 percent of cases exhibited alternative drainage. No significant changes were documented between 1 and 6 months postoperatively. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Bilateral one-stage single-port sympathicotomy in primary focal hyperhidrosis, a prospective cohort study: treat earlier?

BACKGROUND: Primary Focal Hyperhidrosis (PFH) has a detrimental effect on Quality of Life. Repetitive, non-curative symptomatic strategies dominate current treatment of PFH, in spite of the availability of an effective and permanent curative treatment like Endoscopic Thoracic Sympathectomy (ETS). Current surgical optimization may allow for a re-established position of sympathetic modulation in this treatment algorithm. We sought to evaluate the safety, effectiveness, and long-term results of a Bilateral One-stage Single-port Sympathicotomy (BOSS) procedure in PFH patients and to identify subgroups benefitting most. METHODS: Prospective analysis of 163 patients, 35 (21.5%) underwent Rib-3 (R3) BOSS for palmar PFH, 58 (35.6%) R3-R5 BOSS for axillary PFH and 70 (42.9%) R3-R5 BOSS for combined palmar/axillary PFH. Effectiveness was measured using Skindex-29 and the Hyperhidrosis Disease Severity Scale (HDSS). RESULTS: Overall Skindex-29-rating (46.5 ± 14.8 preoperatively vs 20.1 ± 20.6 postoperatively, p < 0.001), and HDSS score (3.71 ± 0.45 preoperatively vs 1.82 ± 0.86 postoperatively, p < 0.001) indicated a significant improvement in health-related quality of life after BOSS. R3 BOSS was superior to R3-R5 BOSS in terms of HDSS score (1.49 vs 1.91 respectively, p = 0.004) and in terms of severe compensatory hyperhidrosis, a frequently reported side-effect (17.1% vs 32.8% respectively, p < 0.001). No major complications occurred. CONCLUSIONS: BOSS is safe, effective, and offers a long-term curative solution in the treatment of PFH. Especially in the palmar PFH subgroup, R3 BOSS treatment results compare favorably to the treatment results of non-curative alternatives published in the current literature. Therefore, R3 BOSS should be offered to all patients with severe PFH, reporting insufficient benefit of treatment options such as oral and/or local agents.

Factors Affecting the Efficacy of Suction Curettage Using an Arthroscopic Shaver for Bromhidrosis.

BACKGROUND: Suction-curettage using an arthroscopic shaver is the most effective surgical treatment for bromhidrosis; however, information regarding the procedure is limited. This study investigated the factors that affect the efficacy of suction-curettage. PATIENTS AND METHODS: We retrospectively evaluated data for 215 patients (430 axillae) with bromhidrosis treated with suction-curettage using an arthroscopic shaver between 2011 and 2019. RESULTS: Excellent or good efficacy with improved malodor was achieved in 418 axillae (97.21%). Secondary suction-curettage was performed for 11 (2.56%), with excellent results. Efficacy and need for secondary suction-curettage were not associated with age, sex, shaving time, and tumescent infiltration use. Complications were observed in 52 (12.09%) axillae, including hematoma or seroma, epidermis decortication, skin necrosis, and infections; 10 (2.33%) required local debridement for wounds. Complications showed a significant difference with respect to age (p < .001). Pain scores on postoperative Day 2 were significantly lower for patients treated using tumescent infiltration than those for the others (1.65 ± 0.84 vs 4.57 ± 1.16; p < .001). CONCLUSION: The results suggest that 7 to 15 minutes of suction curettage using an arthroscopic shaver is sufficient to achieve good efficacy for bromhidrosis with few complications. Older age was a risk factor for complications, and tumescent infiltration use achieved good postoperative pain control. LEVELS OF EVIDENCE: II.

Endoscopic Axillary Approach Improves Patient Satisfaction of Gynecomastia Subcutaneous Mastectomy: A Cross-Sectional Study Using the BODY-Q Chest Module.

BACKGROUND: Gynecomastia is a common condition that refers to the benign enlargement of male breasts. Several minimally invasive techniques were invented to avoid visible scars in the chest area, but have limited effects on the dense fibroglandular breast tissue, and open excision remains the mainstay of treatment. Endoscopic subcutaneous mastectomy has the superiority of visualization, facilitating accurate dissection and hemostasis, also enabling inconspicuous scars. This study was designed to evaluate the patient-reported outcomes of the endoscopic axillary approach in treating gynecomastia, to interpret the differences between it and the conventional periareolar open excision method, and to present our experience utilizing this technique as a reliable alternative for Simon I and II gynecomastia. METHODS: Eighty-three participants diagnosed with Simon I or II gynecomastia were included in this cross-sectional study, among which 31 were preoperative and 52 were postoperative patients. Postoperative participants were divided into two groups according to whether endoscopic axillary subcutaneous mastectomy (axillary group, n = 25) or periareolar open excision (periareolar group, n = 27) was performed. Patient-reported outcomes were assessed using the BODY-Q questionnaire, including the chest, nipples, body image, social, appearance-related distress, and scar domain, with scores ranging from 0 to 100. RESULTS: The BODY-Q score of both axillary and periareolar postoperative groups showed significant improvement on chest (p < 0.001), nipples (p < 0.001), body image (p < 0.001), and appearance-related distress (p < 0.005) scales, compared with the preoperative group. Of the scar scale, the axillary group rated higher scores than the periareolar group (p = 0.019), analysis of the individual scale items showed more positive responses in questions "Location of your scars?" (p < 0.001) and "How your scars look when they are not covered by clothes?" (p < 0.001), the item "Having to dress in a way to hide your scars?" also had a somewhat more positive responses from participants (p = 0.095). CONCLUSIONS: The present findings indicate that compared with the periareolar excision, patients who underwent gynecomastia subcutaneous mastectomy through endoscopic axillary approach have higher scar satisfaction with postoperative outcomes, this probably because of the well-hidden scar at the axilla, which leverages the psychologic burden of the patient after surgery. Future prospective studies are needed to measure changes over the entire patient journey, to find out the predictable factors of postoperative patient satisfaction, and determine how the objective outcomes relate to changes in patient's health-related quality of life.

Ultrasound guided surgery under Dilutional Local Anaesthesia and no sedation in breast cancer patients.

BACKGROUND: Breast cancer surgery under local anaesthesia (LA) can be challenging due to limitation of dose and quantity of anaesthetic agent that can be used safely. Elderly patients with breast cancer and with multiple co-morbidities are often prevented from having a standard treatment as they are considered unfit for general anaesthesia. We describe a technique of surgery under local anaesthesia without sedation that employs dilution to generate large volumes of LA and infiltration under ultrasound guidance. METHODS: We present a case series by a single surgeon of breast cancer patients who underwent surgery under LA. 40 mls of 1% lignocaine with 1:200,000 adrenaline was diluted with 160 mls of normal saline to make a total of 200 mls, resulting in dilution to a concentration of 0.2% lignocaine. Radioactive isotope having been injected before patient's arrival in theatre, 1 ml of diluted anaesthetic solution is used with 2 mls of 2.5% patent blue to inject in the sub-areolar space. Local anaesthetic is infiltrated at operative site under ultrasound guidance using a long echogenic needle. RESULTS: A total of 71 patients with breast cancer underwent surgery under the LA between September 2015 and October 2018. 64 (90%) patients had wide local excisions and 7 (10%) had mastectomies. All had axillary surgery, 65 (91.5%) had dual technique sentinel lymph node biopsy as a day case and 6 (8.5%) patients had axillary clearance. 8 patients had re excision (12.5%). All patients had '0' pain score and no postoperative analgesia was required in recovery. Local anaesthetic used did not exceed the maximum safe dose in any of the cases. One patient returned to theatre for postoperative wound bleeding. No other postoperative complication was observed. CONCLUSION: Ultrasound guided infiltration allows accurate placement of large volume of diluted local anaesthetic solution safely and provides effective anaesthesia.

A new indocyanine green fluorescence lymphography protocol for identification of the lymphatic drainage pathway for patients with breast cancer-related lymphoedema.

BACKGROUND: Breast cancer related lymphoedema (BCRL) is a common side effect of cancer treatment. Recently indocyanine green (ICG) fluorescent lymphography has become a popular method for imaging the lymphatics, however there are no standard protocols nor imaging criteria. We have developed a prospective protocol to aid in the diagnosis and therapeutic management of BCRL. METHODS: Lymphatic imaging procedures were conducted in three phases. Following initial observation of spontaneous movement of ICG in phase one, manual lymphatic drainage (MLD) massage was applied to facilitate ICG transit via the lymphatics in phase two. All imaging data was collected in phase three. Continuous lymphatic imaging of the upper limb was conducted for approximately an hour and lymphatic drainage pathways were determined. Correlations between the drainage pathway and MD Anderson Cancer Centre (MDACC) ICG lymphoedema stage were investigated. RESULTS: One hundred and three upper limbs with BCRL were assessed with this new protocol. Despite most of the patients having undergone axillary node dissection, the ipsilateral axilla drainage pathway was the most common (67% of upper limbs). We found drainage to the ipsilateral axilla decreased as MDACC stage increased. Our results suggest that the axillary pathway remained patent for over two-thirds of patients, rather than completely obstructed as conventionally thought to be the case for BCRL. CONCLUSIONS: We developed a new ICG lymphography protocol for diagnosing BCRL focusing on identification of an individual patient's lymphatic drainage pathway after lymph node surgery. The new ICG lymphography protocol will allow a personalised approach to manual lymphatic drainage massage and potentially surgery.

Lymph drainage of the upper limb and mammary region to the axilla: anatomical study in stillborns.

PURPOSE: We studied the lymphatic drainage of the upper limb and mammary region directing to the axilla to investigate whether independent pathways can be observed or whether anastomoses and shared drainage occur between them. This analysis aimed to assess the safety of axillary reverse mapping (ARM) in breast cancer treatment and to understand the development of lymphedema after sentinel lymph node biopsy (SLNB) alone. METHODS: Seven unfixed stillborn fetuses were injected with a modified Gerota mass in the peri-areolar area, palm and dorsum of the hands, formalin fixed, and then submerged in 10% hydrogen peroxide solution. Microsurgical dissection was then performed on the subcutaneous cellular tissue of the upper limb, axillary region, and anterior thorax to expose the lymphatic vessels and lymph nodes. RESULTS: The dye injected into the upper limb reached either the lateral axillary group, known to be exclusively responsible for upper limb drainage, or the anterior group, which is typically related to breast drainage. There was great proximity among the pathways and lymph nodes. Communicating lymphatic vessels among these groups of lymph nodes were also found in all studied cases. DISCUSSION: Lymphedema remains a challenging morbidity in breast cancer treatment. ARM and SLNB aim to avoid unnecessary damage to the lymphatic drainage of the upper limb. However, our anatomical study suggests that ARM may have potential oncological risks because preserved lymph nodes may harbor malignant cells due their proximity, overlapping drainage pathways, and connecting lymph vessels among lymph nodes.

Postsurgical Outcomes and Surgical Completeness of Robotic Thyroid Surgery: A Single Surgeon's Experience on 700 Cases.

BACKGROUND: Advanced technology and understanding of robotic surgical system have rendered robotic thyroid surgery more expanding. The aim of this study was to identify the periodic changes in postsurgical outcomes of robotic thyroid surgery performed by a single surgeon. METHODS: We conducted a retrospective review of 700 robotic thyroid surgery cases using gasless trans-axillary approach. RESULTS: All patients underwent successful operations without conversion to open surgery, and were mostly younger than 45 years, female, less-extended thyroid surgery and lymph node dissection, and thyroid cancer. The median follow-up period was 67 months (12-99 months). Regarding technical outcomes, the operation time declined steeply after 100 consecutive cases, and reached 120.0-132.7 minutes for thyroid lobectomy and 162.9-174.1 minutes for total thyroidectomy (TT). The most common complication was transient hypoparathyroidism (43.7%), whose incidence decreased steeply to a range of 9.1% to 25.0% after 300 consecutive cases. Regarding surgical completeness for thyroid cancer, an average of seven lymph nodes was retrieved through central compartment node dissection without fluctuation over time. The proportion of the patients with serum stimulated thyroglobulin levels <10 ng/mL at the time of radioactive iodine remnant ablation after TT and <1 ng/mL 6-12 months after the first remnant ablation ranged between 86.4%-100% and 66.7%-100%, respectively, without significant fluctuation. CONCLUSION: For properly selected patients, robotic thyroid surgery is useful surgical option with reliable technical outcome and surgical completeness and cosmetic benefit.

Effectiveness of Fibrin Sealant Patch in Reducing Drain Volume after Pelvic Lymph Node Dissection in Women with Gynecologic Malignancy.

BACKGROUND: The goal of this study was to evaluate the effectiveness of fibrin sealant in decreasing postoperative lymphatic drainage in women after pelvic lymphadenectomy and/or para-aortic lymphadenectomy during gynecologic cancer surgery. METHODS: This study is a retrospective case-control study. Forty-five patients who underwent staging surgery were enrolled. Twenty-seven patients were in the fibrin sealant group (group A) and 18 in the control group (group B). The two groups were compared for the total volume of drain, hospital stay, harvested lymph node, and incidence of asymptomatic lymphocele. Lymphocele formation was evaluated by computed tomography (CT) on 3 months after surgery. RESULTS: There were no significant differences in patient demographics between group A and B with respect to age, BMI, and harvested lymph nodes. Patients who received fibrin sealants had reduced total volume of drainage from postoperative days 2 to 5 compared to the control group (group A versus group B: 994.819 ± 745.85 ml versus 1847.89 ± 1241.41 ml; P = 0.015). However no differences were observed in hospital stay (P = 0.282), duration of drain (P = 0.207), and incidence of asymptomatic lymphocele at 3 months (P = 0.126). CONCLUSION: The results of this study indicate that the application of fibrin sealants after pelvic and/or para-aortic lymphadenectomy may reduce lymphatic drainage in gynecologic malignancy.

Upper Extremity Lymphedema After Axillary Lymph Node Dissection: Prospective Lymphoscintigraphic Evaluation.

This prospective study was designed to evaluate changes in upper extremity lymphatic drainage after ALND in comparison to the preoperative status using lymphoscintigraphy. The study enrolled 44 women (mean age: 57.95; range: 35-80) with a new diagnosis of unilateral invasive breast carcinoma who had been scheduled to undergo ALND. This was a substudy of the physiotherapeutic project, in which subjects after ALND were randomized into 4 groups treated with: 1) rehabilitation exercises; 2) manual lymphatic drainage; 3) pneumatic compression pump; and 4) education only. Clinical evaluation which included arm measurements and lymphoscintigraphy was performed in every subject before surgery and 3 times after surgery (1-6 weeks, 1 and 2 years after ALND). Follow-up was completed in 44 subjects at 1 year and in 32 subjects at 2 years. Lymphedema diagnosis was made in 4 subjects 1 year after ALND (9%) and in 8 subjects 2 years after ALND (25%). Among them, respectively, only 50% and 62% noticed and reported lymphedema. Quantitative analysis of lymphoscintigrams and photoplethysmography results did not reveal upper extremities lymphatic transport and/or venous function impairment after the ALND procedure. Qualitative analysis of lymphoscintigrams revealed most commonly disappearance of previously functional lymph nodes and appearance of dermal backflow in subjects who developed lymphedema. Conversely, appearance of functional lymph nodes in different locations after ALND may indicate protection from development of upper extremity lymphedema.

Prevention and management of lymphedema after breast cancer treatment.

Lymphedema of the arm after breast cancer treatment continues to challenge clinicians worldwide. In this review, we examine the main modalities, both nonsurgical and surgical, to prevent and treat this as yet incurable condition.

Local injection of botulinum toxin A: an alternative therapy for axillary osmidrosis.

The objective of this study was to investigate the efficacy of local injection of botulinum toxin A for treating axillary osmidrosis. One hundred and fifty patients with axillary osmidrosis were randomly divided to receive botulinum toxin A injection treatment (50 U of botulinum toxin A was injected intracutaneously into 6-20 different sites within each axilla, n = 74) or surgical excision of the apocrine glands (n = 76). The patients were followed up for 1-3 months to analyze the therapeutic effect and complications of the two methods. The curative effect in patients with mild and moderate axillary osmidrosis was not significantly different between the botulinum toxin A injection group and operation group. However, for patients with severe axillary osmidrosis, surgery treatment seemed to be superior to botulinum toxin A treatment (P = 0.005). There was also no significant difference in the modified Dermatology Life Quality Index between the two treatments. Two cases showed complications related to hemorrhage and incision infection in the operation group. In conclusion, local injection of botulinum toxin A is a safe, fast and effective treatment for mild and moderate axillary osmidrosis, but the long-term effect remains to be further investigated.

Irradiación de áreas ganglionares en pacientes sin linfadenectomía axilar / Axillary radiation in patients without axillary lymphadenectomy

La biopsia selectiva del ganglio centinela (BSGC) es actualmente una propuesta estándar para la estadificación de la axila en pacientes con cáncer de mama con una clara tendencia a minimizar la cirugía axilar incluso en presencia de ganglio centinela (GC) positivo. En caso de GC negativo la BSGC ha reemplazado a la linfadenectomía axilar (LA) demostrando equivalente supervivencia, mientras que los más sólidos consensos (American Society of Clinical Oncology) y, hasta fechas recientes, las guías de la National Comprehensive Cancer Network recomendaban completar la LA cuando se identifican metástasis en el GC. Esto da como resultado un excelente control locorregional y proporciona información que permite tomar decisiones sobre tratamientos adyuvantes tanto al oncólogo médico como al oncólogo radioterápico. No obstante, en los últimos tiempos múltiples estudios han debatido el valor terapéutico de la linfadenectomía quirúrgica, cobrando especial relevancia a raíz de la publicación del ensayo del American College of Surgeons Oncology Group (ACOSOG) Z0011, en el que se cuestiona el valor de esta actitud terapéutica y se propone únicamente una BSGC, omitiéndose la LA, en pacientes seleccionadas con uno o 2 GC positivos. La evidencia científica nos dice que la radioterapia puede jugar un papel fundamental en el control de la enfermedad axilar y, a fecha de hoy, no sabemos si la baja tasa de recidiva a este nivel, en los estudios mencionados, puede estar influida por la irradiación de la mama y axila inferior. Serían necesarios estudios con un diseño apropiado para contestar esta pregunta. En ausencia de más datos, nuestra propuesta es la irradiación axilar valorando individualmente los factores de riesgo de recidiva locorregional(AU)

Sentinel lymph node biopsy (SLNB) is currently a standard approach for staging of the axilla in patients with breast cancer, with a clear tendency to minimize surgery even in the presence of a positive axillary sentinel lymph node (SLN). The strongest consensus (American Society of Clinical Oncology) and, until recently, the National Comprehensive Cancer Network guidelines used to recommend complete axillary lymphadenectomy when metastases were identified in the SLN. However, SLNB has replaced axillary lymphadenectomy in SLN-negative patients and has demonstrated equivalent survival. This approach results in excellent locoregional control and provides information that allows both the medical oncologist and the radiation oncologist to take decisions about adjuvant treatments. Many recent studies, however, have debated the therapeutic value of surgical lymphadenectomy. This debate has become particularly important after the publication of the trial of the American College of Surgeons Oncology Group (ACOSOG) Z0011, which questions the value of this therapeutic approach and proposes SLNB alone, without lymphadenectomy, in selected patients with one or 2 positive SLN. The scientific evidence indicates that radiotherapy may play a major role in the control of axillary disease and, to date, it is not known whether the low recurrence rate in the axilla reported in the above-mentioned studies may have been influenced by radiation of the breast and lower axilla. To answer this question, new and appropriately designed trials are needed. In the absence of more data, we propose the use of axillary radiation, but with assessment of the risk factors for locoregional recurrence in each patient(AU)

High Ki67 predicts unfavourable outcomes in early breast cancer patients with a clinically clear axilla who do not receive axillary dissection or axillary radiotherapy.

AIM: Axillary dissection is increasingly forgone in early breast cancer patients with a clinically negative axilla. The GRISO 053 randomised trial recruited 435 patients of age over 45 years, tumour ≤1.4 cm and clinically negative axilla, to assess the importance of axillary radiotherapy versus no axillary radiotherapy in patients not given axillary dissection. In the present study on a subgroup GRISO cases our aim was to assess the prognostic importance of tumour biological factors after more than 10 years of follow-up. METHODS: We retrospectively assessed biological factors in a subgroup of 285 GRISO cases (145 given axillary radiotherapy; 140 not given axillary radiotherapy) with complete biologic, therapeutic and follow-up information, using multivariable Cox proportional hazards regression modelling. RESULTS: Only 10-year cumulative incidence of distant metastasis was lower in the axillary radiotherapy (1%) than no axillary radiotherapy arm (7%) (p=0.037). Irrespective of study arm, hormone receptor positivity had significantly favourable effects on 10-year disease-free survival (DFS) and overall survival. human epidermal growth factor receptor 2 (HER2)-positive and triple-negative subtypes were associated with lower 10-year DFS (60% and 76%, respectively) than luminal A (96%) and B (91%) (p=0.001). Ten-year DFS for high (≥14%) Ki67 cancers was lower than for low Ki67 cancers (p=0.027); however, this effect was mainly confined to the no axillary radiotherapy arm. CONCLUDING STATEMENT: For patients with clinically node-negative small breast cancer not given axillary dissection, 10-year DFS is worsened by HER2 positivity, triple-negative phenotype and high Ki67. Axillary radiotherapy counteracts the negative prognostic effect of high Ki67 in patients not receiving axillary dissection.

Ipsilateral nodal recurrence after axillary dissection for breast cancer.

INTRODUCTION: Level I/II axillary lymph node dissection (ALND) is the standard operation for patients with node-positive breast cancer. The objective of this study was to assess the incidence of regional nodal recurrence (RNR) after ALND performed for definitive operative treatment for primary breast cancer. MATERIALS AND METHODS: A retrospective, Institutional Review Board-approved query of our single-institution National Comprehensive Cancer Network database was performed for patients undergoing ALND who developed subsequent RNR. All patients were treated from 1999 to 2009. A detailed chart review was performed and clinical, pathologic, treatment, and outcome data were collected. RESULTS: A total of 1614 patients had an ALND for initial staging; 14/1614 (0.9%) patients had RNR. Two other patients had contralateral breast/axillary recurrences and were excluded. The mean age at diagnosis for the sample group was 52.7 y (range 34-77); mean follow-up time was 47.1 mo (range 12.6-114.6). The median number of nodes for ALND was 16 (range 8-27). The median number of positive nodes was 2.5 (range 0-7). Nine (64.3%) cases were estrogen receptor/progesterone receptor negative. Twelve (85.7%) patients had axillary recurrences, and six of 12 (50.0%) had concurrent chest wall lesions. Twelve patients (85.7%) had distant metastases; nine of 12 (75.0%) died; two were lost to follow-up. Mean time from RNR to distant recurrence was 6.0 mo (range 0-29.3 mo). CONCLUSIONS: RNR after ALND is rare but a harbinger of poor outcome. This is apparent regardless of treatment used for initial disease or recurrence. Specifically, RNR after primary ALND is related to increased risk of mortality and distant metastatic disease.

Assessing second echelon lymph nodes during sentinel lymph node biopsy: can we have more accurate axillary treatment for breast cancer patients?

Sentinel lymph node biopsy (SLNB) is the standard treatment for breast cancer patients with clinically negative axilla. For patients with positive sentinel lymph nodes, axillary lymph node dissection (ALND) was required. However, approximately a half of the SLNs-positive patients were found to have clear axillary lymph nodes after ALND, indicating that they had received unnecessary ALND without therapeutic benefit. Therefore, we propose a hypothesis for solution of this clinical problem. We defined the second echelon lymph nodes (SELNs) as those nodes receiving lymphatic drainage directly from the SLNs. For patients with positive-SLNs, SELNs can be biopsy and assessed. If SELNs are negative, no more ALND was needed in these patients even if their SLNs are positive. If our hypothesis were confirmed to be true, we can tailored our axillary treatment to more breast cancer patients, avoiding unnecessary ALND and its complications.
