Complications of level I and II axillary dissection in the treatment of carcinoma of the breast

Effectiveness of TachoSil as Sealant in Lymphatic Leakage of Breast Cancer With Axillary Dissection

Objectives: This study is aimed at evaluating the effectiveness of TachoSil in controlling lymphatic leakage in breast cancer patients undergoing axillary dissection. By examining its ability to reduce postsurgical lymphatic drainage, the study will assess its impact on complications like seroma formation, recovery time, and overall patient outcomes, including quality of life and reduced healthcare costs. Methods: Breast cancer patients treated in the Department of Surgical Oncology at King Abdulaziz Medical City were enrolled to receive either TachoSil or undergo drain placement after axillary dissection. Repeated measures multivariate analysis of variance (MANOVA) was used to observe the difference in lymphatic drainage volume over time considering other covariates, such as age, sex, family history, neoadjuvant chemotherapy (NAC), and stage. Results: The TachoSil group showed significantly lower lymphatic drainage volumes at 24 h (106.5 ± 11.3) than the control group (141.7 ± 13.0) (p < 0.001). There were no significant differences in lymphatic drainage volume at 3 days (p = 0.176) and 7 days (p = 0.091). However, at 10 days, the TachoSil group exhibited significantly lower lymphatic drainage volume (19.9 ± 6.1) than the control group (44.5 ± 9.2) (p < 0.001). Repeated measures MANOVA showed a statistically significant difference in lymphatic drainage over time, with a moderate effect (p < 0.001). Conclusion: The findings suggest that TachoSil sealant effectively reduces early postoperative lymphatic drainage volume and maintains lower drainage rates up to 10 days following axillary dissection in breast cancer patients. The use of TachoSil sealant may have potential benefits in reducing the incidence of complications associated with lymphatic drainage and improving patient outcomes.

Randomized comparison between ultrasound-guided proximal and distal approaches of intercostobrachial nerve block as an adjunct to supraclavicular brachial plexus block for upper arm arteriovenous access procedures

BACKGROUNDS

Ultrasound-guided proximal and distal approaches of the intercostobrachial nerve (ICBN) blocks facilitate analgesia for upper arm and axillary surgery, though success rates vary and lack clinical comparison. This study compared their anesthetic and analgesic efficacy as an adjunct to the supraclavicular brachial plexus block for upper arm arteriovenous access surgery.

METHODS

60 end-stage renal disease patients undergoing upper arm arteriovenous access were randomly assigned to receive either proximal or distal ICBN block using 10 mL of a mixture of levobupivacaine and lidocaine with epinephrine. The primary outcome was a successful ICBN block, defined as a cutaneous sensory blockade at both the medial upper arm and axilla 30 min after the block. Secondary outcomes included block performance, block-related complications, rate of surgical anesthesia, and postoperative analgesia.

RESULTS

The proximal approach had a higher percentage of sensory blockade at the axilla (96.7% vs 73.3%, p=0.03), but comparable rates at the medial upper arm (96.7% vs 96.7%, p=1.00). Consequently, the proximal approach had a higher overall success rate (96.7% vs 73.3%, difference: 23.3%; 95% CI: 6.3%, 40.4%; p=0.03). Both groups had similar surgical anesthesia rates of 93.3%. No significant differences were found in performance time, procedural pain, or postoperative pain intensity.

CONCLUSIONS

Proximal ICBN block consistently reduced sensation in the medial upper arm and axilla, while one-quarter of distal blocks spared the axilla. Both approaches, in combination with a supraclavicular brachial plexus block, were effective for upper arm arteriovenous access procedures. However, the proximal approach may be preferable for axillary surgery.

Efficacy of frozen section in sentinel lymph node biopsy in early breast cancer - An Australian single-centre experience

Introduction

Sentinel lymph node biopsy (SLNB) is the standard of care for axillary staging in patients with clinically lymph node negative early breast cancer, reducing the need for axillary lymph node dissection (ALND) and its associated risks. Intra-operative frozen section is a method of rapid pathological assessment of the sentinel node to identify the presence of metastatic disease and potentially avoid the need for a second operation in patient who will require an axillary lymph node dissection.

Methods

A retrospective review of a prospectively collected breast cancer database was performed. All patients with breast cancer who underwent SLNB and/or ALND at our institution, between May 1st 2017 to June 1st 2022 were identified. There were 565 patients who were included in the study.

Results

Intra-operative frozen section was able to accurately identify 71% of patients who had macrometastasis in their sentinel lymph node, thus allowing them to immediately proceed to ALND and avoid a second operation. In patient who had a false negative frozen section result, only 6.5% required ALND. The majority of false negative results were due to isolated tumour cells or micrometastasis, and therefore would not have required further intervention.

Conclusion

Intra-operative frozen section of sentinel lymph node biopsy in breast cancer is useful in reducing the need for a second operation, allowing staging of the axilla to occur more efficiently and with high diagnostic accuracy.

Suction Drain Volume following Axillary Lymph Node Dissection for Melanoma-When to Remove Drains? A Retrospective Cohort Study

Postoperative complications such as seroma formation and wound-site infection occur following completion axillary lymph node dissection (ALND) for melanoma. We analyzed the impact of time-to-drain removal and drainage volume on seroma formation after ALND. We retrospectively analyzed data from 118 patients after completion ALND for melanoma. Primary endpoints were daily amount of drainage volume, seroma formation and time-to-drain removal. Secondary endpoints included patient-related, disease-specific and perioperative parameters as well as the number of histologically analyzed lymph nodes and surgical complications graded by the Clavien−Dindo classification (CDCL). Statistical analyses were performed using logistic regression models. Drain removal around the 8th postoperative day was statistically associated with a lower risk for the occurrence of seroma formation (p < 0.001). Patients with an increased drainage volume during the early postoperative days were more prone to develop seroma after drain removal. With 49% (CDCL I and II), most complications were managed conservatively, while only 5.9% (CDCL III) required revision surgery (CDCL overall: 55.9%). ALND is a safe procedure with a low rate of severe CDCL III type of complications. To decrease seroma evacuation, our results imply that drains should be removed around the 8th postoperative day to reduce the risk of infection, readmission or prolonged hospitalization.

The diagnostic accuracy of intraoperative frozen section biopsy for diagnosis of sentinel lymph node metastasis in breast cancer patients: a meta-analysis

Sentinel lymph node (SLN) sampling is important for evaluating the nodal stage of breast cancer when the axillary nodes are clinically free of metastasis. The intraoperative frozen section (IFS) of SLN is used for lymph node assessment. This meta-analysis aims to provide evidence about the diagnostic accuracy and the applicability of IFS of SLN in breast cancer patients. Data were collected by searching PubMed, Cochrane, Scopus, and Web of Science electronic databases for trials matching our eligibility criteria. The statistical analysis included the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and pooled studies' diagnostic odds ratio outcomes. The analyses were conducted using the Open Meta-analyst software. This meta-analysis pooled the results of 110 studies. The overall sensitivity of IFS for SLN metastasis was 74.7%; 95% CI [72.0, 77.2], P < 0.001. It was 31.4% 95% CI [25.2, 38.3], P < 0.001 for the micro-metastasis, and 90.2%; 95% CI [86.5, 93.0], P < 0.001 for the macro-metastasis. The overall specificity was 99.4%; 95% CI [99.2, 99.6], P < 0.001. The overall positive likelihood ratio was 121.4; 95% CI [87.9, 167.6], P < 0.001, and the overall negative likelihood ratio was 0.226; 95% CI [0.186, 0.274], P < 0.001. The overall diagnostic odds ratio of IFS for diagnosing SLN metastasis was 569.5; 95% CI [404.2, 802.4], P < 0.001. The intraoperative frozen section of SLN has good sensitivity for diagnosing breast cancer macro-metastasis. However, the sensitivity is low for micro-metastasis. The specificity is very satisfactory.

Prevention of lymphocele or seroma after mastectomy and axillary lymphadenectomy for breast cancer: systematic review and meta-analysis

Seroma or lymphocele remains the most common complication after mastectomy and lymphadenectomy for breast cancer. Many different techniques are available to prevent this complication: wound drainage, reduction of the dead space by flap fixation, use of various types of energy, external compression dressings, shoulder immobilization or physical activity, as well as numerous drugs and glues. We searched MEDLINE, clinicaltrials.gov, Cochrane Library, and Web of Science databases for publications addressing the issue of prevention of lymphocele or seroma after mastectomy and axillary lymphadenectomy. Quality was assessed using Hawker's quality assessment tool. Incidence of seroma or lymphocele were collected. Fifteen randomized controlled trials including a total of 1766 patients undergoing radical mastectomy and axillary lymphadenectomy for breast cancer were retrieved. The incidence of lymphocele or seroma in the study population was 24.2% (411/1698): 25.2% (232/920) in the test groups and 23.0% (179/778) in the control groups. Neither modification of surgical technique (RR 0.86; 95% CI [0.72, 1.03]) nor application of a medical treatment (RR 0.96; 95% CI [0.72, 1.29]) was effective in preventing lymphocele. On the contrary, decreasing the drainage time increased the risk of lymphocele (RR 1.88; 95% CI [1.43, 2.48). There was no publication bias but the studies were of medium to low quality. To conclude, despite the heterogeneity of study designs, drainage appears to be the most effective technique, although the overall quality of the data is low.

Application of the Machine-Learning Model to Improve Prediction of Non-Sentinel Lymph Node Metastasis Status Among Breast Cancer Patients

Background

Performing axillary lymph node dissection (ALND) is the current standard option after a positive sentinel lymph node (SLN). However, whether 1–2 metastatic SLNs require ALND is debatable. The probability of metastasis in non-sentinel lymph nodes (NSLNs) can be calculated using nomograms. In this study, we developed an individualized model using machine-learning (ML) methods to select potential variables, which influence NSLN metastasis.

Materials and Methods

Cohorts of patients with early breast cancer who underwent SLN biopsy and ALND between 2012 and 2021 were created (training cohort, N 157 and validation cohort, N 58) for the development of the nomogram. Three ML methods were trained in the training set to create a strong predictive model. Finally, the multiple iterations of the least absolute shrinkage and selection operator regression method were used to determine the variables associated with NSLN status.

Results

Four independent variables (positive SLN number, absence of lymph node hilum, lymphovascular invasion (LVI), and total number of SLNs harvested) were combined to generate the nomogram. The area under the receiver operating characteristic curve (AUC) value of 0.759 was obtained in the entire set. The AUC values for the training set and the test set were 0.782 and 0.705, respectively. The Hosmer-Lemeshow test of the model fit accuracy was identified with p = 0.759.

Conclusion

This study developed a nomogram that incorporates ultrasound (US)-related variables using the ML method and serves to clinically predict the non-metastatic status of NSLN and help in the selection of the appropriate treatment option.

The role of tranexamic acid in breast and body contouring surgery: a review of the literature

Background: Postoperative seroma and haematoma are two of the most common complications follow-ing large surface area surgeries. A review of the literature was performed to evaluate evidence for the use of tranexamic acid in reducing postoperative seroma and haematoma formation in breast surgery and body contouring surgery. Methods A literature search was performed using MEDLINE, the Cochrane Database of Systematic Review, the Cochrane Central Register of Controlled Trials (CENTRAL), the Database of Abstracts of Reviews of Ef-fect (DARE) and PubMed in English from 1 Jan 1990–30 Mar 2020. The search terms ‘TXA’, ‘breast reduction’, ‘mammaplasty’, ‘breast implants’, ‘breast implantation’, ‘breast reconstruction’, ‘mastectomy’, ‘tissue ex-pansion’, ‘body contouring’, ‘breast’ and ‘abdominoplasty’ were used alone and in combination. Results: A total of six articles were found including three randomised controlled trials, two cohort studies and one retrospective study. Two ongoing trials were found on The Cochrane Central Register of Con-trolled Trials (CENTRAL). No systematic reviews were found. Conclusion: Literature surrounding the use of TXA in breast and body contouring surgery is sparse com-pared to what is available in other surgical sub-specialties. The literature available shows promising results with the use of TXA in controlling haematoma, drain output and seroma formation in breast surgery and body contouring surgery with minimal morbidity in these patient groups.

Evolving Trends in Surgical Management of Breast Cancer: An Analysis of 30 Years of Practice Changing Papers

The management of breast cancer has evolved into a multidisciplinary evidence-based surgical speciality, with emphasis on conservative surgery. A number of landmark trials have established lumpectomy followed by radiation as the standard of care for many patients. The aim of this study is to construct a narrative review of recent developments in the surgical management of breast cancer and how such developments have impacted surgical practice. A comprehensive literature search of Pubmed was conducted. The latest search was performed on October 31^st, 2020. Search terms “breast cancer” were used in combinations with specific key words and Boolean operators relating to surgical management. The reference lists of retrieved articles were comprehensively screened for additional eligible publications. Articles were selected and reviewed based on relevance. We selected publications in the past 10 years but did not exclude commonly referenced and highly regarded previous publications. Review articles and book chapters were also cited to provide reference on details not discussed in the academic literature. This article reviews the current evidence in surgical management of early-stage breast cancer, discusses recent trends in surgical practice for therapeutic and prophylactic procedures and provides commentary on implications and factors associated with these trends.

The Findings of SPECT/CT Concerning Bypass Lymph Circulation in Lymphedema Following Breast Cancer Surgery

This study aimed to determine whether bypass circulation was present in lymphedema and its effect. This was a retrospective, cross-sectional study. Patients who underwent unilateral breast cancer surgery with axillary lymph node dissection were recruited and underwent single-photon emission tomography/computed tomography (SPECT/CT). SPECT/CT was performed to detect the three-dimensional locations of radio-activated lymph nodes. Patients with radioactivity in anatomical locations other than axillary lymph nodes were classified into a positive group. All patients received complete decongestive therapy (CDT). Exclusion criteria were as follows: History of bilateral breast cancer surgery, cervical lymph node dissection history, and upper extremity amputation. The difference in the upper extremity circumference (cm) was measured at four points: Mid-point of the upper arm, elbow, and 10 and 15 cm below the elbow. Twenty-nine patients were included in this study. Fifteen patients (51.7%) had bypass lymphatic systems on the affected side, six (20.7%) had a bypass lymphatic system with axillary lymph nodes on the unaffected side, and 11 (37.9%) showed new lymphatic drainage. The positive group showed significantly less swelling than the negative group at the mid-arm, elbow, and 15 cm below the elbow. Bypass lymphatic circulation had two patterns: Infraclavicular lymph nodes and supraclavicular and/or cervical lymph nodes. Changes in lymph drainage caused by surgery triggered the activation of the superficial lymphatic drainage system to relieve lymphedema. Superficial lymphatic drainage has a connection through the deltopectoral groove.

Uncomplicated Arthroscopic Rotator Cuff Repair in Chronic Ipsilateral Upper Extremity Lymphedema: A Case Report

CASE

A 69-year-old woman with chronic upper extremity lymphedema secondary to bilateral mastectomy and axillary lymph node dissection for breast cancer 10 years before presented to the clinic with a massive rotator cuff tear. Her shoulder pain and dysfunction persisted despite nonoperative treatment. She underwent left shoulder arthroscopic rotator cuff repair (RCR) and biceps tenotomy. Arm, forearm, and wrist circumference measurements were obtained, preoperatively, immediately postoperatively, and 1-week and 2-weeks postoperatively. No permanent increase in extremity circumference measurements was observed.

CONCLUSION

This case suggests that it is possible to perform an arthroscopic RCR in a patient with chronic upper extremity lymphedema without creating further morbidity.

A Model to Predict the Risk of Lymph Node Metastasis in Breast Cancer Based on Clinicopathological Characteristics

Background

Sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND) may cause lymphatic and nervous system side effects in patients with breast cancer. It is imperative to develop a model to evaluate the risk of sentinel lymph node metastasis to avoid unnecessary operation.

Patients and Methods

A total of 2705 cases of female breast cancer patients enrolled in this retrospective study. We divided into the training group (SLNB group) and the validation group (ALND group) to analyze the relathionship between lymph node metastasis and clinical-pathological factors. Logistic regression analysis was performed to verify the variables which involved in ALN metastasis and established a prediction model. ROC curves were employed to evaluate the predictive ability of the model.

Results

In the SLNB group, 9 variables, including pathological type, histological grade, tumor size, hormone receptor, HER-2, Ki-67, multifocality, and molecular subtypes, were related to breast cancer ALN metastasis. Clinically negative lymph nodes, favorable histologic type, tumor size <2 cm, and Ki-67 <15% were at very low risk for lymph node metastasis. The AUC of the validation group was 0.786.

Conclusion

We successfully establish a mathematics model to predict lymph node metastasis of breast cancer. Axillary surgery should be individual with preoperative clinical characteristics, especially for patients with a longer life expectancy.

Repeat Sentinel Lymph Node Biopsy for Ipsilateral Breast Tumor Recurrence After Breast Conserving Surgery With Sentinel Lymph Node Biopsy: Pooled Analysis Using Data From a Systematic Review and Two Institutions

Introduction: Best surgical approach of axillary staging remains controversial in locally recurrent breast cancer. We evaluated the reliability of repeat sentinel lymph node biopsy (reSLNB) in patients with ipsilateral breast tumor recurrence (IBTR) after breast conserving surgery (BCS) with sentinel lymph node biopsy (SLNB) in terms of identification rate (IR) and false negative rate (FNR). To address the FNR, we identified patients who underwent sequential axillary lymph node dissection (ALND) after reSLNB.

Methods: A systematic search of PubMed, EMBASE, and Cochrane Library were conducted to identify patient-level data from articles. We searched for data of patients who underwent BCS with SLNB for primary breast cancer and who underwent sequential ALND after reSLNB due to local recurrence. Patients data was also identified by the same criteria at two institutions.

Results: In total, 197 peer-reviewed publications were obtained, of which 20 included patients who met the eligibility criteria. Data from 464 patients were collected. From the two institutions, 31 patients were identified. A total of 495 patients were pooled. The IR of reSLNB was 71.9% (356/495). To address the FNR of reSLNB, 171 patients who underwent ALND after reSLNB were identified. The FNR and accuracy of reSLNB were 9.4% (5/53) and 97.1% (165/170), respectively.

Conclusion: Our pooled data analysis showed that the FNR of reSLNB is lower than 10%, indicating that this operation is a reliable axillary surgery in patients with IBTR after they underwent BCS.

Periclavicular Lymph Node Activation Maintains the Lymphatic Circulation of Upper Extremity Following Breast Cancer Surgery with Axillary Lymph Node Dissection

Backgrounds: Axillary lymph node dissection (ALND) can cause breast cancer-related lymphedema (BCRL). However, ALND does not always produce lymphedema to the breast cancer survivors. Therefore, we aimed to investigate the correlation between the finding of lymphoscintigraphy and lymphedema in patients undergoing breast cancer surgery with ALND. Methods and Results: Patients with BCRL (n = 73, mean age: 53.92 ± 11.13 years) after full ALND (levels I, II, and III) were retrospectively included in this study. All patients underwent lymphoscintigraphy and according to the findings of the imaging, patients were divided into three groups: negative group, periclavicular lymph nodes (P-LN) activation, and axillary lymph nodes (A-LN) activation. According to the extent of radiation therapy, groups were classified as the following: no radiation group (None), breast radiation group (BI), and breast irradiation in addition to P-LN (BI+PC). The percentage difference in the upper extremities was used as the marker of severity of lymphedema. The subjects in the negative group, P-LN, and A-LN were 34 (46.6%), 33 (45.2%), and 6 (8.2%) patients, respectively. The findings of lymphangiography showed statistically significant relationship with the severity of lymphedema. The extent of radiation therapy did not have statistically significant relationship. Despite ALND, 53.4% patients had active L/N capable of removing the upper limb lymphatic fluids and 45.2% patients showed activation of collateral formation of lymphatic circulation after ALND. Conclusion: The collateral lymphatic formation was provoked after breast cancer operation with ALND, which decreased the severity of lymphedema in breast cancer survivors.

Effects of Fibrin Sealant on Seroma Reduction for Patients with Breast Cancer Undergoing Axillary Dissection: Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Seroma formation is common in patients with breast cancer after axillary dissection. Fibrin sealant, containing fibrinogen and thrombin, has been developed to improve wound healing. We conducted a systematic review and meta-analysis to evaluate the efficacy of fibrin sealants in reducing seroma among patients with breast cancer undergoing axillary dissection.

METHODS

We searched the PubMed, EMBASE, and Cochrane Library databases for randomized controlled trials (RCTs) published up to April 2020. Pooled estimates of the outcomes were computed using a random-effects model. The primary outcomes were incidence and volume of seroma, while the secondary outcomes were volume and duration of drainage, incidence of infection, and length of hospital stay.

RESULTS

We reviewed 23 RCTs that included 1640 patients. Compared with the control group, the fibrin sealant group had no significant differences in the incidence of seroma, length of hospital stay, or incidence of surgical site infection. Significant intergroup differences were discovered in lower volume of seroma (weighted mean difference [WMD] - 71.88, 95% confidence interval [CI] - 135.58 to - 8.19), volume of drainage (WMD - 73.24, 95% CI - 107.32 to - 39.15), and duration of drainage (WMD - 0.84, 95% CI - 1.50 to - 0.19).

CONCLUSIONS

Fibrin sealants provide limited benefits in reducing the volume of seroma and the volume and duration of drainage. Therefore, after shared decision making, surgeons may apply fibrin sealants to patients with breast cancer undergoing axillary dissection.

Effect of evidence-based nursing intervention on upper limb function in postoperative radiotherapy patients with breast cancer

To investigate the effect of evidence-based nursing (EBN) intervention on upper limb function in postoperative breast cancer patients undergoing radiotherapy.A total of 126 breast cancer patients who had received postoperative radiotherapy in the Union Hospital affiliated with Tongji Medical College, Huazhong University of Science and Technology from September 2017 to September 2018 were randomly divided into 2 groups, namely, experimental and control groups, with 63 cases in each group. Both the control and experimental groups received routine postoperative radiotherapy followed by traditional and EBN interventions, respectively. All patients were followed up for 6 months and differences in the upper limb function after nursing intervention were compared between the 2 groups.The scores of self-rating anxiety scale (SAS), self-rating depression scale (SDS), and short form-36 survey (SF-36) in the 2 groups had no statistical significance before intervention. After the EBN intervention, the SAS and self-rating depression scale scores of patients in the experimental group were lower than that of those in the control group. In the experimental group, 90.67% of the patients had an excellent score for the University of California, Los Angeles shoulder score, which was higher than that of the control group (73.92%). The Mayo Elbow Performance Score of the experimental group (95.01) was higher than that of the control group (91.33). The total length of the sum of arm circumference in the experimental group was (128.39 cm) lower than that of the control group (143.66 cm). The scores of SF-36 in the overall health, physical pain, mental health, and physiological functions of the patients in the experimental group were higher than those of the control group. All of these parameters' differences between the 2 groups were of statistical significance (P < .05).EBN can positively influence the negative emotional state of breast cancer patients after radiotherapy. At the same time, it is helpful in reducing the degree of lymph node edema on the affected side of the upper limb, thereby improving the function of the shoulder joint, which has a positive effect on the upper limb function.

Axillary Lymph Node Dissection for Breast Cancer: Efficacy and Complication in Developing Countries

Purpose

Axillary lymph node dissection (ALND) frequently is performed as part of the surgical management of breast cancer as a therapeutic and prognostic index, but increasingly has been perceived as associated with significant complications. Data on efficacy and complications of ALND in Sudan are lacking. The aim of this study was to assess the efficacy and complications of ALND in patients with breast cancer treated with mastectomy and breast-conserving surgery.

Methods

We performed a prospective, hospital-based study in women with invasive breast cancer who underwent modified radical mastectomy or breast-conserving surgery with ALND between September 2014 and August 2015. The efficacy of ALND was defined as retrieval of ≥ 10 lymph nodes. Complications of ALND were assessed objectively and subjectively and defined as either present or absent.

Results

Of 96 patients with breast cancer included in the study, 40 (42%) developed postaxillary clearance complications. The median follow-up time was 18 months (range, 12 to 24 months). Numbness was reported by 21.9% of patients. Seroma was noted in 15.6% and lymphedema in 9.4%. Approximately 9% reported episodes of infection or inflammation at the surgical site. None of the studied factors were found to affect the incidence of complications significantly. Ten or more lymph nodes were retrieved in 81.3% of patients, and nodal metastasis was found in 62.5%.

Conclusion

This study shows that the prevalence of undesirable adverse effects after ALND is 42%, with paresthesia and seroma being the most prevalent. The lymphedema prevalence was low in relation to other evaluated symptoms.

Outcomes of shoulder arthroplasty following axillary lymph node dissection

INTRODUCTION

Shoulder arthroplasty with previous axillary lymph node dissection historically has unsatisfactory outcomes. We analyzed outcomes of primary shoulder arthroplasty in patients with previous axillary lymph node dissection.

METHODS

Thirty-two primary shoulder arthroplasties after prior axillary lymph node dissection were performed. These patients were analyzed for patient-reported outcomes, range of motion, complications, and reoperations.

RESULTS

Average age was 70.8 ± 7.5 years old. There were 19 anatomic total shoulder arthroplasties, four hemiarthroplasties, and nine reverse total shoulder arthroplasties. Eight were performed by a superior approach while 24 were performed by a deltopectoral approach with cephalic vein preservation. There were three complications (one deltoid dehiscence, one axillary nerve palsy, and one postoperative pneumonia). There was one revision (hemiarthroplasty to reverse total shoulder arthroplasty for cuff failure at 91 weeks), two reoperations, and no infections. Patient-reported outcomes were available for 21/26 (80.1%) of the surviving shoulders at 4.8 ± 2.0 years. Average visual analog scale pain score was 7.1 ± 14.5, Simple Shoulder Test score 8.3 ± 2.6 "yes" responses, Single Assessment Numeric Evaluation score 80.2 ± 17.4, and American Shoulder and Elbow Surgeons score 83.6 ± 14.1.

CONCLUSION

Axillary lymph node dissection is not a contraindication to shoulder arthroplasty. A deltopectoral exposure can be utilized without substantial risk of worsening lymphedema or wound complications. While a superior approach avoids cephalic vein injury, important approach-related complications (deltoid dehiscence and axillary nerve palsy) were observed.Level of evidence: Level IV-case series.

Interneural tissue clearance in axillary dissection for breast cancer: What is the importance?

BACKGROUND

Breast cancer is the most common cancer in women and second most common type of cancer overall. The prime objectives of axillary surgery in the management of breast cancer are 1) accurate staging, 2) treatment to cure and 3) quantitative information of metastatic lymph nodes for prognostic purposes and allocation to adjuvant protocols. During axillary dissection, all 3 level lymphnodes are removed, while the important axillary structures (axillary vein, long thoracic and thoracodorsal nerves) are preserved. The latter two structures are particularly vulnerable to injury when dissecting the tissue between them (the interneural tissue).

METHODS

This prospective non-randomized study, conducted on 125 female patients, who underwent axillary lymphadenectomy for breast cancer has evaluated the importance of dissection of the Interneural tissue during axillary dissection in breast cancer surgery by reviewing the lymph node yield and metastasis rate. The interneural tissue was excised separately after a routine axillary dissection.

RESULTS

Lymph nodes were found in the interneural tissue of 70 out of 125 patients (56%). The average number of interneural lymph nodes recovered per specimen was 1.3. The interneural tissue lymph nodes were positive for metastasis in 10 (8%) patients. There was no incidence of isolated metastasis in the internerve tissue nodes.

CONCLUSIONS

There is a significant incidence of lymph nodes (56%) and axillary node metastases (8%) in the tissue lying between the long thoracic and thoracodorsal nerves. Therefore, meticulous dissection and excision of this interneural tissue is strongly recommended to optimize decision making regarding adjuvant treatment and outcome.

Immunohistochemistry and Reverse Transcriptase Polymerase Chain Reaction on Sentinel Lymph Nodes can Improve the Accuracy of Nodal Staging in Breast Cancer Patients

In this study the nodal staging sensitivity of sentinel lymph node biopsy (SLNB) with detailed pathological and molecular biological examination has been investigated and compared to that of axillary lymph node dissection (ALND) with routine histological evaluation. Sentinel lymph nodes (SLNs) were removed by the dual-agent injection technique in 68 patients with primary, clinically node-negative breast cancer. Forty-seven patients had negative SLNs according to hematoxylin and eosin (H&E) staining. These H&E-negative SLNs were serially sectioned and examined at 250 μm levels by anticytokeratin immunohistochemistry (IHC). In 14 patients the SLNs were also investigated by cytokeratin 20 (CK20) reverse transcriptase polymerase chain reaction (RT-PCR). SLNB with IHC increased the node-positive rate by 26% (by 40% in tumors less than or equal to 2 cm in size (pT1) and by 9% in tumors more than 2 cm but less than or equal to 5 cm in size (pT2)). The sensitivity of SLNB with IHC was superior to that of ALND with routine histology in pT1 tumors and identical in pT2 tumors. The concordance between histology and RT-PCR was only 21%, and in two of three cases with positive histological results RT-PCR was negative. In conclusion, SLNB with detailed pathological and/or molecular biological evaluation can improve the sensitivity of regional staging. ALND can probably be abandoned in patients with pT1 SLN-negative breast cancer. Further prospective studies are required to determine the clinical significance of these detailed SLN evaluation techniques, but at present these methods are still investigational.

The Efficacy of Fibrin Sealant Patches in Reducing the Incidence of Lymphatic Morbidity After Radical Lymphadenectomy: A Meta-Analysis

BACKGROUND

Although pivotal in the oncological management of most tumors, radical lymphadenectomy is associated with a significant number of lymphatic complications. The aim of this meta-analysis is to evaluate the efficacy of fibrinogen sealant patches in reducing lymphadenectomy-related postoperative complications.

METHODS/MATERIALS

The electronic databases PubMed, Medline, and Scopus were searched using the terms "lymphadenectomy" or "lymph node dissection" and "TachoSil," "TachoComb," or "fibrin sealant patch." Series evaluating the efficacy of fibrin-thrombin collagen sealant patches were included in the meta-analysis.

RESULTS

Overall, 26 studies were retrieved through the literature search. Ten studies including 720 patients met selection criteria. The use of fibrin-thrombin sealant patches to the sole scope of reducing lymphadenectomy-related complications significantly reduced the incidence of lymphocele, symptomatic lymphocele, the need of percutaneous drainage procedures, the volume of lymph drained, and the duration of the drainage. No effect on wound and/or lymphocele infection was noted.

CONCLUSIONS

This meta-analysis demonstrates that the use of fibrin-thrombin sealant patches significantly reduces the total volume of lymph drained, the duration of the drainage, the incidence of lymphocele and symptomatic lymphocele, and the need for postoperative percutaneous drainage procedures. Its use does not affect the incidence of wound or lymphocele infections.

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.

Sentinel Lymph Nodes for Breast Carcinoma: A Paradigm Shift

CONTEXT

-Sentinel lymph node biopsy has been established as the new standard of care for axillary staging in most patients with invasive breast carcinoma. Historically, all patients with a positive sentinel lymph node biopsy result underwent axillary lymph node dissection. Recent trials show that axillary lymph node dissection can be safely omitted in women with clinically node negative, T1 or T2 invasive breast cancer treated with breast-conserving surgery and whole-breast radiotherapy. This change in practice also has implications on the pathologic examination and reporting of sentinel lymph nodes.

OBJECTIVE

-To review recent clinical and pathologic studies of sentinel lymph nodes and explore how these findings influence the pathologic evaluation of sentinel lymph nodes.

DATA SOURCES

-Sources were published articles from peer-reviewed journals in PubMed (US National Library of Medicine) and published guidelines from the American Joint Committee on Cancer, the Union for International Cancer Control, the American Society of Clinical Oncology, and the National Comprehensive Cancer Network.

CONCLUSIONS

-The main goal of sentinel lymph node examination should be to detect all macrometastases (>2 mm). Grossly sectioning sentinel lymph nodes at 2-mm intervals and evaluation of one hematoxylin-eosin-stained section from each block is the preferred method of pathologic evaluation. Axillary lymph node dissection can be safely omitted in clinically node-negative patients with negative sentinel lymph nodes, as well as in a selected group of patients with limited sentinel lymph node involvement. The pathologic features of the primary carcinoma and its sentinel lymph node metastases contribute to estimate the extent of non-sentinel lymph node involvement. This information is important to decide on further axillary treatment.

Bilayered negative-pressure wound therapy preventing leg incision morbidity in coronary artery bypass graft patients: A randomized controlled trial

BACKGROUNDS

The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a clinical randomized controlled trial.

METHODS

A single-center, pilot randomized controlled trial was conducted. From December 2013 to March 2014, a total of 72 coronary heart disease patients (48 men and 24 women) received CABG therapy, with great saphenous veins were selected as grafts. Patients were equally randomized into a treatment and a control group. After the harvesting of the great saphenous veins and direct closure of the wound with sutures, b-NPWT was used for the thigh incision in the treatment group for 5 days (treatment thigh). Traditional surgical pads were applied to both the shank incisions of the treatment group patients (treatment shank) and the entire incisions of the control group (control thigh, control shank). Postoperative complications were recorded and statistically analyzed based on outcomes of thigh treatment, shank treatment, thigh control, and shank control groups.

RESULTS

The incidence rates of early complications, such as lymphorrhagia, lymphoedema, infection, wound dehiscence, and skin flap necrosis, of the vascular donor site in the thigh treatment group was significantly lower than those in the 3 other groups.

CONCLUSIONS

The self-designed b-NPWT can effectively reduce postoperative complications, such as lymphedema, incision infection, wound dehiscence, and skin flap necrosis, in CABG patients who underwent great saphenous veins harvesting.

Multidisciplinary management of breast cancer

Breast cancer, with an increasing incidence, is the most frequently diagnosed cancer in women worldwide. The treatments proposed, generally a combination of surgery, radiotherapy, chemotherapy, endocrine therapy and/or targeted therapy, are constantly improving, allowing a reduction in the mortality rate, but they are still causing many side effects, not only early but also late, which leads us to consider the post-cancer period as a chronic condition. Side effects, reviewed in this commentary, may affect physical functions, psychological status, social situation, body composition, well-being and quality of life of the patient. In view of the extent of these areas in which side effects of breast cancer and of its treatments can be found, the supportive care offered at the end of treatment need to be multidisciplinary. Different supportive care interventions may be proposed to the patients such as psychological and behavioral interventions, complementary therapies, diet interventions, physical activity/rehabilitation or also physiotherapy interventions for example, all having shown some beneficial effects in the literature. The benefits of these supportive care interventions are thereby already established and they are described in this article, but others studies will be needed to clearly define indications and most optimal modalities of application to reduce side effects and improve quality of life of patients.

Prospective randomized controlled study to assess the value of a hemostatic and sealing agent for preventing seroma after axillary lymphadenectomy

BACKGROUND AND OBJECTIVES

Postoperative seroma after axillary lymphadenectomy leads to an increased use of resources and an impaired quality of life of patients. This randomized clinical trial was designed to assess the value of a hemostatic and sealing agent for decreasing seroma occurrence after axillary lymphadenectomy.

METHODS

A prospective, randomized, blind study was conducted on 91 axillary lymphadenectomies distributed into a control group (n = 47) and a test group in which a collagen sponge coated with human coagulation factors was used (n = 44). Primary end-points were number of days before removal of axillary drainage, axillary drainage output, and occurrence of seroma, wound infection, haematoma, or wound dehiscence, within 8 weeks of surgery. Bivariate and multivariate analyses on seroma occurrence were performed.

RESULTS

Seroma occurred in 29 patients (31.86%). A significant direct relationship (P = 0.002) was only noted between use of the hemostatic and sealing agent and nonoccurrence of seroma. In the multivariate study, the only variable found to be significantly related to seroma occurrence was use of the above agent (P = 0.046; odds ratio: 3.365 [95%CI: 1.024-11.060]).

CONCLUSIONS

Use of a collagen sponge coated with human coagulation factors following axillary lymphadenectomy was associated to a lower incidence of postoperative seroma. J. Surg. Oncol. 2016;114:423-427. © 2016 Wiley Periodicals, Inc.

Axillary radiotherapy: an alternative treatment option for adjuvant axillary management of breast cancer

Axillary lymph node dissection is standard management of axilla in invasive breast cancer. Radiotherapy also is important in local treatment. It is controversial as to whether axillary radiotherapy can displace axillary lymph node dissection. We performed a meta-analysis comparing axillary radiotherapy with axillary dissection. No significant difference was observed for disease free survival and overall survival between the radiation group and the dissection group. There was also no significant difference in either the axillary recurrence or the local recurrence between the two groups. But the axillary relapse rate in the radiation group was higher than in the surgery group at five-year follow-up while the local recurrence rate in the surgery group was higher than in the radiation group. A subgroup analysis showed that the difference in the axillary recurrence rate (RR = 0.20, P = 0.01) and local recurrence rate (RR = 4.7, P = 0.01) mainly appeared in the clinical node-positive subgroup. The edema rate in the surgery group was higher than in the radiation group (RR = 2.08, 95%: 1.71–2.54, P < 0.0001). We concluded that radiotherapy may be an alternative treatment option for adjuvant management of the axilla in selected sub-groups of patients.

Axillary reverse lymphatic mapping reduces patient perceived incidence of lymphedema after axillary dissection in breast cancer

BACKGROUND

Lymphedema is a feared complication of many patients following axillary lymph node dissection for breast cancer. Axillary reverse lymphatic mapping (ARM) was adopted to decrease the incidence of lymphedema.

METHODS

A retrospective review was conducted on 139 patients with breast cancer who had greater than 10 lymph nodes removed. A survey was sent to patients to identify those with lymphedema.

RESULTS

One hundred nine women were contacted via mail survey to determine the presence of lymphedema. Of the 46 surveys returned, the incidence of lymphedema was 39%. Twenty-seven percent of the ARM group identified themselves as having lymphedema compared with 50% in non-ARM group. Eighteen percent of women in the ARM group needed an arm sleeve for treatment compared with 45.8% in the non-ARM group.

CONCLUSIONS

The incidence of perceived lymphedema and the need for arm compression sleeve devices were lower in the ARM cohort. ARM should be adopted to decrease patient perception of lymphedema.

The Added Value of a Single-photon Emission Computed Tomography-Computed Tomography in Sentinel Lymph Node Mapping in Patients with Breast Cancer and Malignant Melanoma

Single-photon emission computed tomography-computed tomography (SPECT-CT) allows for physiological and anatomical co-registration in sentinel lymph node (SLN) mapping and offers additional benefits over conventional planar imaging. However, the clinical relevance when considering added costs and radiation burden of these reported benefits remains somewhat uncertain. This study aimed to evaluate the possible added value of SPECT-CT and intra-operative gamma-probe use over planar imaging alone in the South African setting. 80 patients with breast cancer or malignant melanoma underwent both planar and SPECT-CT imaging for SLN mapping. We assessed and compared the number of nodes detected on each study, false positive and negative findings, changes in surgical approach and or patient management. In all cases where a sentinel node was identified, SPECT-CT was more accurate anatomically. There was a significant change in surgical approach in 30 cases - breast cancer (n = 13; P 0.001) and malignant melanoma (n = 17; P 0.0002). In 4 cases a node not identified on planar imaging was seen on SPECT-CT. In 16 cases additional echelon nodes were identified. False positives were excluded by SPECT-CT in 12 cases. The addition of SPECT-CT and use of intra-operative gamma-probe to planar imaging offers important benefits in patients who present with breast cancer and melanoma. These benefits include increased nodal detection, elimination of false positives and negatives and improved anatomical localization that ultimately aids and expedites surgical management. This has been demonstrated in the context of industrialized country previously and has now also been confirmed in the setting of a emerging-market nation.

Serum fibronectin 1 and ApoE levels increase with risk of lymphedema in Korean breast cancer survivors

PURPOSE

Lymphedema is an irreversible disorder often seen as a postoperative side effect in breast cancer survivors. We aimed to identify serum factors that are associated with lymphedema risk in breast cancer survivors.

METHODS

This study recruited 60 volunteer breast cancer survivors. Participants were classified into either a CTRL group who underwent sentinel lymph node biopsy (SLNB), a RISK group who underwent axillary lymph node dissection (ALND) with removal of fewer than five lymph nodes, or an LE group who underwent ALND with removal of more than five lymph nodes. Bioimpedance was measured to determine the ratio of extracellular water (ECW) to total cellular water (TCW) and single-frequency bioimpedance analysis (SFBIA) ratios. Serum lipid profiles were compared among the groups using label-free quantitative proteomics with the nano-liquid chromatography (LC)-tandem mass spectrometer (MS/MS) and emPAI method.

RESULTS

The CTRL, RISK, and LE groups had similar body weights and body mass indexes (BMIs) (<25 kg/m(2)). The LE group showed a higher grade of lymphedema severity compared to the RISK and CTRL groups. Lymphedema indices such as the ECW/TCW ratio and SFBIA ratio at 1 and 5 kHz were greatly increased in the LE group. Serum total cholesterol (total-C) level was higher in the LE group without affecting atherogenic index. Serum proteomics revealed that fibronectin 1 (FN1), apolipoprotein E (ApoE), antithrombin (ANT3), and complement C4 had different abundance values among the groups. ELISA confirmed that FN1 and ApoE were significantly elevated in both the RISK and LE groups compared to the CTRL group.

CONCLUSIONS

Changes in serum FN1 and ApoE levels were detected prior to changes in serum total-C level and lymphedema indices such as SFBIA ratio. Therefore, elevation in serum FN1 and ApoE concentrations could likely be used to monitor the risk of lymphedema in breast cancer survivors.

Ultrasound-guided scraping of fibrous capsule plus bilayered negative pressure wound therapy for treatment of refractory postmastectomy seroma

INTRODUCTION

Seroma is a frequent complication of breast cancer surgery. Treatment of prolonged or refractory seroma remains a clinical challenge. This study aimed to evaluate the efficacy of a novel approach for refractory seroma treatment; the method combines minimally invasive scraping for fibrous capsule removal and self-designed bilayered negative pressure wound therapy (b-NPWT) to achieve favorable wound healing.

METHODS

Twenty-four patients with refractory seroma received ultrasound-guided scraping of fibrous capsule around the refractory seroma, and then a bilayered NPWT system simultaneously allowing for fluid drainage and dynamic topical pressure was manually implemented immediately. The time of NPWT application and wound healing was recorded, and pathological examination was conducted for the removed fibrous tissues.

RESULTS

Removal of the fibrous capsule was securely achieved by minimally invasive scraping through a 1.5-cm incision guided with ultrasound scanning. All refractory seromas in the 24 patients healed uneventfully after an average application of NPWT for 7.2±3.3 days without recurrence during the 3-12 months of follow-up. Biopsy of the removed fibrous tissue demonstrated that single-layered endothelial cells stained with CD31, D2-40, and Ki-67 existed both on the surface of and inside the fibrous tissue.

CONCLUSIONS

The combination of fibrous capsule removal by ultrasound-guided scraping with successive bilayered NPWT therapy is effective and minimally invasive for promoting wound healing of refractory postmastectomy seroma.

OSNA (one-step nucleic acid amplification) sentinel lymph node intraoperative molecular analysis in breast cancer: a cost-benefit analysis

The aim of the study was to analyze the medical and economic interest of OSNA molecular technique, compared to conventional postoperative histopathologic evaluation for sentinel lymph node exploration in breast cancer patients. This retrospective cost-benefit study was conducted in the French Universitary Hospital of Saint Etienne on patients who received sentinel lymph node exploration between July 1, 2007 and December 31, 2009. Lymph nodes were analyzed by conventional postoperative histological evaluation in group 1 (82 patients) and OSNA in group 2 (86 patients). Costs were analyzed in three different ways: surgery cost, hospitalization cost and histopathologic cost. Average operating time was slightly shorter for group 1 (histology) [71.9 vs. 76.8 min for group 2 (OSNA)]. Time and operating costs were not significantly different (p = 0.293). The average cost of pathological examination was significantly higher in group 2 (35.04 euros per node in group 1 vs. 291.84 euros per node in group 2 p < 10(-3)). The average length of hospital stay was significantly longer in group 1 (5.4 days in group 1 vs. 4.2 days in group 2, p = 0.0065). The total costs were not significantly different between both groups (3,774.6 euros in group 1 vs. 3,393.9 euros in group 2 p = 0.055). The sentinel lymph node analysis with OSNA technique does not lead to higher expenses. It also avoids another surgery for 20% of patients. A prospective multicentric medico-economic study made with a larger effective would probably confirm these results.

The effects of low-thrombin fibrin sealant on wound serous drainage, seroma formation and length of postoperative stay in patients undergoing axillary node dissection for breast cancer. A randomized controlled trial

BACKGROUND

Breast cancer surgery with axillary lymphadenectomy may be associated with prolonged stay of the drain in the axilla due to high wound output, which may require further treatments and prolong the length of stay, impairing quality of life. No definitive data are available concerning how to prevent this complication. Our aim was to assess the efficacy of a new low-thrombin fibrin glue in reducing the serous output from the axillary surgical wound in patients undergoing axillary node dissection for breast cancer, and its long-term effects on lymphedema.

METHODS

Sixty patients undergoing surgery between September 2012 and June 2013 were enrolled. Thirty patients received Artiss®(Baxter, UK) fibrin glue plus drainage, and 30 drainage alone. A multivariate analysis was performed to identify predictors of seroma, and subgroup analyses were performed. Lymphedema was assessed 12 months after surgery.

RESULTS

Patients who received fibrin glue had reduced serum output collected in the drain after surgery (94.3 ± 22.4 vs 176 ± 24.6 ml p < 0.001) and shorter length of postoperative hospital stay (p = 0.001). Incidence of seroma at 4-week follow-up did not differ between groups. At multivariate analysis, BMI ≥ 30 kg/m(2) was the only independent predictor of seroma formation (OR = 2.7, 95%CI 1.4-5.3; p = 0.002). Overweight patients receiving Artiss® had fewer seroma at 4-week follow-up compared with control overweight patients (0% vs 55.6%, p = 0.03). No differences were observed in lymphedema between groups (6.7% vs 10%, p > 0.99).

CONCLUSIONS

Low-thrombin fibrin glue reduced the amount of fluid produced in the axilla after breast surgery. Overweight patients may be the ideal candidates for this treatment. Such sealant did not increase the rates of lymphedema.

Potential risk factors for the development of seroma following mastectomy with axillary dissection

Seroma is a common complication following breast cancer surgery and the controllable predictive factors remain unknown. Patients who underwent mastectomy with axillary dissection between 2008 and 2011 in our hospital were retrospectively investigated. The demographics, clinical characteristics and therapeutic factors of each patient were recorded. The association of seroma incidence with each variable was evaluated by univariate logistic regression analysis. All the variables were considered independent predictors of seroma incidence. The probability of developing seroma following surgery was evaluated by multivariate logistic regression analysis. A total of 102 patients, with a mean age of 54.86±13.02 years (range, 30-89 years), were included in this study and the incidence of seroma was found to be 22.55%. The operative time (P=0.0066, coefficient = 0.0261, OR=1.03) and the use of patient-controlled intravenous analgesia (PCA) (P=0.0002, coefficient = -1.8089, OR=0.03, ref = no) was significantly associated with the incidence of seroma postoperatively. In conclusion, the prediction of the development of seroma following mastectomy with axillary dissection is challenging. However, a longer operative time and the non-use of PCA may represent potential risk factors for this complication.

Axillary treatment for patients with early breast cancer and lymph node metastasis: systematic review protocol

BACKGROUND

For patients with early breast cancer and lymph node metastasis, axillary treatment is widely recommended. This is either surgical removal of the axillary lymph nodes, or axillary radiotherapy. The rationale for axillary treatment is that it will reduce the risk of recurrence in the axilla, and may improve survival. However, both treatments are associated with adverse effects, such as lymphedema, pain and sensory loss, and are costly to the health services and to patients. With improvements in adjuvant therapy, routine axillary treatment may no longer offer any overall advantage.

OBJECTIVES

To assess the short and long term benefits and adverse effects of routine axillary treatment (axillary lymph node clearance or axillary radiotherapy) for patients with lymph node positive early-stage breast cancer.

METHODS/DESIGN

Criteria for potentially eligibility for the study will be that the participants are men and women with early breast cancer and lymph nodes with metastasis. The study compares either axillary treatment with no axillary treatment, or axillary node clearance with axillary radiotherapy, and the study is a randomized trial. Primary outcomes are axillary recurrence, disease-free and overall survival. Secondary outcomes include breast or chest wall recurrence, distant metastasis, time to axillary recurrence, axillary recurrence-free survival, arm morbidity, quality of life and health economic costs. The search strategy will include the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and WHO International Clinical Trials Registry Platform (ICTRP) search portal. Two independent reviewers will assess studies for inclusion in the review, assess study quality and extract data. Characteristics of included studies will be described. Meta-analysis will be conducted using ReVman software.

COMMENT

This review addresses an important clinical question, and results will inform clinical practice and health care policy.

Effectiveness of OK-432 (Sapylin) to reduce seroma formation after axillary lymphadenectomy for breast cancer

BACKGROUND

The occurrence of seroma formation after axillary lymphadenectomy for breast cancer cannot be ignored. Various approaches have been used in an effort to reduce it, but these results are still controversial. We aimed to describe a new method of application of OK-432 (Sapylin, heat-treated Su strain of Streptococcus) to reduce seroma formation after axillary lymphadenectomy for breast cancer and to verify the safety and efficacy of it as a beneficial supplement for conventional surgery.

METHODS

A prospective, randomized analysis of consecutive quadrantectomy or mastectomy plus axillary lymphadenectomy using or not using OK-432 was designed. From July 2010 to November 2011, a total of 111 patients were enrolled in this prospective, randomized study and completed the follow-up. OK-432 applied to the axillary fossa plus placement of closed suction drainage was used in 54 patients (the experimental group); placement of closed suction drainage was used in 57 patients (the control group).

RESULTS

There were no statistical significance between the two groups in terms of age, body mass index, treatment received, tumor size, number of removed lymph nodes, and lymph node status. Postoperative drainage magnitude and duration were significantly reduced in the experimental group (P = 0.008 and 0.003, respectively). One week after hospital discharge, fewer patients developed a palpable seroma in the experimental group: 10 in the experimental group versus 28 in the control group (P = 0.001). Fewer seromas needed aspiration (mean 1 [range 0-3] in the experimental group vs. mean 4 [range 1-5] in the control group; P < 0.001). There were no significant differences in terms of the incidence of complications associated with axillary lymphadenectomy (P = 0.941).

CONCLUSIONS

OK-432 is a feasible and safe option for axillary lymphadenectomy for breast cancer. The use of it does not always prevent seroma formation, but it can reduce drainage magnitude and duration, as well as decrease the incidence of seroma after the removal of drainage. It may be increasingly conducted in day surgery clinics.

Efficacy of fibrin glue on seroma formation after breast surgery

Background and Objectives. This study was designed to determine the effectiveness of fibrin glue plus conventional drain placement versus conventional drain placement in the prevention of seromas after breast procedures. Among methods employed to reduce seroma magnitude and duration, fibrin glue has been proposed in numerous studies, with controversial results. Design and Setting. A prospective, randomized, controlled study of subjects who were randomized into control and experimental groups was conducted. Methods. Collected data included age, surgeon, medical and surgical history, comorbidities, procedure performed, number of axillary nodes, number of positive axillary nodes collected, final pathologic diagnosis, cancer stage, hospital stay, postoperative day of drain removal, complications, incidence of seroma formation, interval to seroma resolution, and number of postoperative visits. Results. Analysis of 60 patients showed similarly matched groups. Seroma formation rate was 24.1% in the control group and 16.1% in the fibrin glue group. The rate of wound complications was similar. Conclusions. Although use of fibrin sealant resulted in a nonsignificant decrease in seroma formation rate compared with that of drain placement, the higher cost and cumbersome technique tend to indicate that there is no advantage to using fibrin glue over drain placement with the technique described.

Lymphatic complications in surgery: possibility of prevention and therapeutic options

The problem of prevention of lymphatic complications in surgery is extremely important if we think about the frequency of both early complications such as lymphorrhea, lymphocele, wound dehiscence and infections and late complications such as lymphangitis and lymphedema. Nowadays, it is possible to identify risk patients and prevent these lesions or treat them at an early stage. This report helps to demonstrate how it is important to integrate diagnostic and clinical findings to better understand how to properly identify risk patients for lymphatic injuries and, therefore, when it is useful and proper to do prevention. Authors report their experiences in the prevention and treatment of lymphatic injuries after surgical operations and trauma. After an accurate diagnostic approach, prevention is based on different technical procedures among which microsurgical procedures. It is very important to follow-up the patient not only clinically but also by lymphoscintigraphy. A protocol of prevention of secondary limb lymphedema was proposed and it includes, from the diagnostic point of view, lymphoscintigraphy and, as concerns therapy, it recognizes also a role to early microsurgery. It is necessary to accurately follow-up the patient who has undergone an operation at risk for the appearance of lymphatic complications and, even better, to assess clinically and by lymphoscintigraphy the patient before surgical operation.

Scapula alata in early breast cancer patients enrolled in a randomized clinical trial of post-surgery short-course image-guided radiotherapy

BACKGROUND

Scapula alata (SA) is a known complication of breast surgery associated with palsy of the serratus anterior, but it is seldom mentioned. We evaluated the risk factors associated with SA and the relationship of SA with ipsilateral shoulder/arm morbidity in a series of patients enrolled in a trial of post-surgery radiotherapy (RT).

METHODS

The trial randomized women with completely resected stage I-II breast cancer to short-course image-guided RT, versus conventional RT. SA, arm volume and shoulder-arm mobility were measured prior to RT and at one to three months post-RT. Shoulder/arm morbidities were computed as a post-RT percentage change relative to pre-RT measurements.

RESULTS

Of 119 evaluable patients, 13 (= 10.9%) had pre-RT SA. Age younger than 50 years old, a body mass index less than 25 kg/m2, and axillary lymph node dissection were significant risk factors, with odds ratios of 4.8 (P = 0.009), 6.1 (P = 0.016), and 6.1 (P = 0.005), respectively. Randomization group was not significant. At one to three months' post-RT, mean arm volume increased by 4.1% (P = 0.036) and abduction decreased by 8.6% (P = 0.046) among SA patients, but not among non-SA patients. SA resolved in eight, persisted in five, and appeared in one patient.

CONCLUSION

The relationship of SA with lower body mass index suggests that SA might have been underestimated in overweight patients. Despite apparent resolution of SA in most patients, pre-RT SA portended an increased risk of shoulder/arm morbidity. We argue that SA warrants further investigation. Incidentally, the observation of SA occurring after RT in one patient represents the second case of post-RT SA reported in the literature.
