Complications associated with mastectomy

The succession of One Day Surgery with Breast Cancer Home Recovery Program by the National Cancer Institute (ODS BHR NCI) during the COVID-19 pandemic in Thailand

Background

Breast cancer is the most common cancer among women. In response to the need to hospital stays and minimize waiting time for surgery, particularly during the COVID-19 pandemic, the National Cancer Institute developed the One Day Surgery with Breast cancer Home Recovery program (ODS BHR NCI). The aim of study is to assess the success rate of breast cancer surgeries conducted through this program and to evaluate the incidence of complications.

Method

The cohort study includes all breast cancer patients who underwent surgery through the ODS BHR NCI program between August 2021 to November 2023. Eligible participants were under 70 years of age. The patients received comprehensive care and education from a multidisciplinary team, adhering to the program's guidelines. Their postoperative outcomes were monitored on the 1st, 3rd, and 5th days following discharge.

Result

A total of 206 patients participated in the ODS BHR NCI program during the COVID-19 pandemic in Thailand. The mean age and BMI were 54.21 ± 9.74 years and 24.18 ± 4.02, respectively. The success rate was 99.02 %, with only one case involving a serious complication. Minor complications were reported in 20 cases, including anesthesia-related issues and minor surgical complications. Notably, no patients were diagnosed with COVID-19 following their surgery.

Conclusion

Breast cancer surgeries performed under the ODS BHR NCI program achieved a high success rate. The development of pre-, intra-, and post-operative care protocols, alongside comprehensive patient education, has potential to reduce complications and provide an effective model for extending systemic care to a wider range of patients.

Axillary Reverse Mapping Aids in Reducing the Rates of Breast Cancer-Related Lymphedema in Underserved Ethnically Diverse Population

BACKGROUND

Breast cancer-related lymphedema (BCRL) poses a significant risk following sentinel lymph node biopsy (SLNB) and axillary lymph node dissection (ALND), particularly affecting ethnic minorities, with a twofold increased risk. Axillary reverse mapping (ARM), a novel technique, shows potential in reducing BCRL rates, yet its utility in ethnic minorities lacks sufficient exploration. Therefore, our study aims to investigate the utility and outcomes of ARM on BCRL in an ethnic diverse group.

METHODS

A retrospective chart review of ARM patients from January 2019 to July 2022 was conducted, monitoring patients over 24 months at 3-month intervals using SOZO® scores, with comparisons with preoperative baselines.

RESULTS

Of the 212 patients, 83% belonged to ethnic minorities. SLNB was performed in 83%, ALND in 17%, and 62.3% underwent radiation therapy. Positive lymph nodes were found in 31.6%, with 22.2% exhibiting blue nodes and 25.9% exhibiting blue lymphatics. Of identified blue nodes, 70.2% were excised, including 51.5% crossover nodes. Lymphedema occurred in 3 patients, resulting in a BCRL rate of 1.4%. Compared with an historical BCRL incidence of 40.4% following ALND in ethnic minorities, our study reported a significantly lower rate of 8% (p < 0.001).

CONCLUSION

The ARM procedure can significantly lower BCRL in ethnic minority groups. The combination of ARM and bioimpedance spectroscopy led to a remarkably low BCRL rate of 1.4%. Notably, none of the patients in our study developed an axillary recurrence at 24-month follow-up. Nevertheless, future studies with larger sample sizes are warranted to better understand the utility of the ARM technique in this population.

Decoding the Mastectomy SKIN Score: An Evaluation of Its Predictive Performance in Immediate Breast Reconstruction

BACKGROUND

The skin ischemia and necrosis (SKIN) score was introduced to standardize the assessment of mastectomy skin flap necrosis (MSFN) severity and the need for reoperation. The authors evaluated the association between the SKIN score and the long-term postoperative outcomes of MSFN after mastectomy and immediate breast reconstruction.

METHODS

The authors conducted a retrospective cohort study of consecutive patients who developed MSFN after mastectomy and immediate breast reconstruction from January of 2001 to January of 2021. The primary outcome was breast-related complications after MSFN. Secondary outcomes were 30-day readmission, operating room (OR) débridement, and reoperation. Study outcomes were correlated with the SKIN composite score.

RESULTS

The authors identified 299 reconstructions in 273 consecutive patients with mean follow-up time of 111.8 ± 3.9 months. Most patients had a composite SKIN score of B2 (25.0%, n = 13), followed by D2 (17.3%) and C2 (15.4%). We found no significant difference in rates of OR débridement ( P = 0.347), 30-day readmission ( P = 0.167), any complication ( P = 0.492), or reoperation for a complication ( P = 0.189) based on the SKIN composite score. The composite skin score was a poor predictor of reoperation, with an area under the curve of 0.56. A subgroup analysis in patients who underwent implant-based reconstruction revealed no difference in rates of OR débridement ( P = 0.986), 30-day readmission ( P = 0.530), any complication ( P = 0.492), or reoperation for a complication ( P = 0.655) based on the SKIN composite score.

CONCLUSIONS

The SKIN score was a poor predictor for postoperative MSFN outcomes and reoperation. An individualized risk-assessment tool that incorporates the anatomic appearance of the breast, imaging data, and patient-level risk factors is needed.

Efficacy and aesthetic outcomes for quilting sutures in the prevention of seroma after mastectomy

Worldwide, mastectomy for breast cancer is one of the most frequently performed surgical procedures. As one of the main complications of mastectomy, seroma is associated with pain, infections and a prolonged hospital stay. We performed a prospective multicenter randomized trial to assess the efficacy and esthetic outcomes associated with quilting the skin flap. Eighty-seven patients were included. The proportion of patients with seroma on postoperative day 15 was significantly lower in the quilting group (12 out of 39 (30.8%)) than in a control group with conventional wound closure (21 out of 40 (52.5%); P = 0.05). The mean breast seroma volume was significantly lower in the quilting group (130.2 mL) than in the control group (236.8 mL; P = 0.02). There were no differences in the esthetic outcomes. The pain level on day 1 was similar in the quilting and control groups (mean visual analog scale score: 2.5 vs. 2.1, respectively; P = 0.3). Quilting the skin flap was associated with a lower prevalence of seroma and a lower seroma volume, and did not worsen the esthetic outcomes or pain levels. This technique is technically straightforward and should be offered to all patients scheduled for mastectomy.

Use of LigaSure vessel sealing system versus conventional axillary dissection in breast cancer patients: a retrospective comparative study

BACKGROUND

In locally advanced breast cancer, axillary lymph node dissection remains a pivotal component of surgical therapy. Apart from this, it has been mostly replaced by sentinel node biopsy. Complications after axillary dissection include wound infection, neuropathy, lymphedema and-most frequently-seroma. In this retrospective multi-centre study, we compared the use of LigaSure^TM with monopolar electrocautery regarding perioperative outcome.

METHODS

A retrospective data analysis from female breast cancer patients who underwent axillary dissection at two breast centres in Austria that are using two different surgical techniques was performed for this study. We compared the rate of complications and re-operations, length of hospital stay, time to drain removal, total drain fluid, seroma formation after drain removal, number of seroma aspirations and total seroma fluid.

RESULTS

Seventy one female patients with a median age of 63 (30-83) were included in this study. In 35 patients LigaSure^TM and in 36 monopolar cautery was used for axillary dissection. There was no significant difference regarding intraoperative complications and rate of re-operations between the two groups (2.9 vs. 5.6%; p = 1 and 2.9 vs. 13.9%; p = 0.199). The time to drain removal and the length of hospital stay was similar in both groups. A significant difference in the occurence of postoperative wound infection could also not be shown. However, we found a significantly smaller total drain fluid in the LigaSure^TM-group compared to the cautery-group (364.6 ml vs. 643.4 ml; p = 0.004). Seroma formation after drain removal was more frequent in the LigaSure^TM-group (68.6 vs. 41.7%; p = 0.032) with a higher number of outpatient seroma aspirations (2.0 vs. 0.9; p = 0.005).

CONCLUSION

LigaSure^TM and monopolar cautery provide equivalent techniques in axillary lymph node dissection with comparable postoperative outcomes.

Effect of Octreotide on Lymphorrhea in Patients After Modified Radical Mastectomy for Carcinoma Breast: A Randomized Controlled Trial

Introduction

Lymphorrhea or seroma formation after modified radical mastectomy (MRM) is a serious and disabling complication of axillary lymphadenectomy. Octreotide is a hormone with general anti-secretory effects. The potential role of octreotide in the treatment of lymphorrhea after axillary lymph node dissection in patients undergoing MRM is being investigated in this study. The purpose of this research is to study the effect of octreotide on the magnitude and duration of lymphorrhea in patients after MRM for carcinoma breast.

Methods

This clinical trial was registered in the Clinical Trials Registry India (CTRI/2017/11/010653). It was conducted in the Department of General Surgery, Maulana Azad Medical College and associated Lok Nayak Hospital, New Delhi from September 2015 to March 2017. This study is a parallel randomized controlled trial with a 1:1 allocation ratio. Thirty patients were enrolled and allocated equally into two groups. The intervention group received standard medical care plus injection octreotide 100 micrograms eight hourly intravenously post-operatively for five days and the control group received only standard medical care. The primary outcomes were lymphorrhea volume from 24 hours post-surgery till five days post-operatively and the number of days till the suction drain was removed. Secondary outcomes were surgical site infection, the incidence of seroma formation, complications of octreotide, duration of hospital stay, and the number of lymph nodes isolated. All the patients were followed up twice a week for the first six weeks after discharge followed by three monthly visits.

Results

A total of 30 patients were included in the study. The mean age was 46.2 years. The mean operative time in the control group was 137.87 ± 23.28 minutes and in the octreotide group was 128.13 ± 12.29 (p = 0.163). The volume of lymphorrhea in the control group was 354.67 ± 346.28 ml and in the octreotide group was 194.00 ± 240.62 ml (p = 0.081). Seroma occurred in 9% of patients in the control group and 2 % of patients in the octreotide group (p = 0.010). The duration of lymphorrhea was 4.93 ± 2.49 days in the control group and 3.13 ± 1.36 days in the octreotide group (p = 0.029). The duration of stay was 7.07 ± 2.40 days in the control group and 5.13 ± 1.06 days in the octreotide and was found to be statistically significant (p = 0.010). No obvious adverse reactions related to injection octreotide, namely, nausea, vomiting, abdominal discomfort, hypotension, bradycardia, and dysglycemia, were seen in any of our patients.

Conclusion

The duration of lymphorrhea, incidence of seroma formation, and duration of hospital stay were lesser in the octreotide group, and the difference was statistically significant. The wound infection rates were similar in both groups. Thus injection octreotide can be used safely and effectively.

Mixed Metal Oxide Nanoparticle Formulations for the Treatment of Seroma

Seroma formation is a well-recognized postoperative complication for many plastic and general surgical procedures. Although various tissue adhesives and substances have been used in an effort to treat seroma formation, no therapies have been established clinically. Recently, the nano-bridging phenomenon has been introduced as a promising approach to achieve tissue adhesion and strong closure of deep skin wounds in rats. The present study seeks to assess the potential of nano-bridging beyond skin wounds in a rat model of seroma. Seromas were induced in 20 Lewis rats through bilateral axillary lymphadenectomy, excision of the latissimus dorsi and cutaneous maximus muscles, and disruption of dermal lymphatics. On postoperative day (POD) 7, the seroma was aspirated on both sides. A bioactive nanoparticle (NP) suspension based on zinc-doped strontium-substituted bioglass/ceria nanoparticles (NP group) or fibrin glue (fibrin group) was injected into the right seroma cavity, while the left side was left untreated. On POD 14, the NP group showed complete remission (no seromas at all), while the fibrin group recorded a reduction of only 63% in the seroma fluid volume. The NPs exerted local anti-inflammatory and neo-angiogenic effects, without any detectable systemic changes. Moreover, the ceria levels recorded in the organs did not surpass the background level, indicating that the nanoparticles stayed at the site of application. This study is a promising first example demonstrating the ability of inorganic nanoparticle formulations to reduce seroma formation in a rat model, without any detectable systemic adverse effects. These results emphasize the potential of nanotechnological solutions in the therapeutic management of seroma in the clinical setting.

Effectiveness of Cyanoacrylate in Reducing Seroma Formation in Breast Cancer Patients Post-Axillary Dissection: A Randomized Controlled Trial

BACKGROUND/PURPOSE

Seroma is a common complication after axillary dissection in women with node-positive breast cancer. We aim to determine the effect of Cyanoacrylate on reducing seroma formation in patients undergoing axillary dissection. This a randomized clinical trial.

METHODS

This is a single-center, randomized, single-blinded, and two-arm parallel study. Women with node-positive breast cancer eligible for axillary dissection were enrolled. Patients with a Body Mass Index (BMI) greater than 35 kg/m2, those who underwent immediate breast reconstruction, and/or received neoadjuvant chemotherapy were excluded. Patients were randomized in a 1:1 ratio, and were stratified according to their age, BMI, tumor size, and operation type. The primary endpoint was the total seroma volume (the total drained volume and the total aspirated volume after drain removal). Data presented as mean and range when applicable.

RESULTS

111 patients were randomized (Cyanoacrylate 57; control 54). 105 patients were analyzed. Sixty-nine patients underwent breast conserving surgery, and 36 underwent modified radical mastectomy. There was no difference in the total seroma volume between the Cyanoacrylate vs. control arms (1,304 (60-4,950) vs. 1,446 (100-5,223) ml, p=0.458). Wound infection, flap necrosis, number of manual aspirates, and hematoma formation were not statistically different between the two groups. Time to drain removal was shorter in the Cyanoacrylate arm (11.04(3-23) vs. 13.84(3-37) days, p=0.015). The use of Cyanoacrylate was not cost effective ($586.93 (550-748) vs. $29.63 (0-198), p<0.001). Higher seroma volume was correlated with modified radical mastectomy, older age, and BMI more than 30 kg/m2.

CONCLUSION

Cyanoacrylate did not reduce seroma formation and its use was not cost effective.

Managing infected seroma post-lymphadenectomy; A retrospective cohort study and cost analysis in melanoma patients

BACKGROUND AND PURPOSE

Seromas are a common and unavoidable complication following lymphadenectomy, and often become clinically significant with superseded infection requiring re-admission for prompt intervention. However, there is no consensus as to whether a formal surgical incision and drainage (I&D), ultrasound (US)-guided aspiration or intravenous (IV) antibiotics alone is the most efficacious method of managing an infected seroma, the investigation of which formed the rationale for this study.

SUBJECTS AND METHODS

This retrospective cohort study included a consecutive series of patients readmitted for infected seroma following a lymphadenectomy for melanoma at Leeds Teaching Hospitals Trust (LTHT) from 2006 to 2017. Details on management, length of hospital stay, length of follow-up and number of clinical appointments required were examined.

FINDINGS

Seventy-one cases of infected seroma were identified from the cohort of 1691 lymphadenectomies. Initially, 21 patients (29.5%) were managed by IV antibiotics alone (failure rate of 52.4%); 18 (25.4%) with US-guided aspiration (failure rate 27.8%) and 32 (45.1%) with surgical I&D, which was 100% effective. Ultimately, 62.5% of the cohort required surgical management. Patients who underwent surgical I&D were discharged significantly faster following the procedure (3 versus 5 days for US-guided aspiration, p = 0.002) and spent fewer days in hospital overall (p = 0.022). The overall average cost was comparable across the three treatment groups.

CONCLUSIONS

Surgical management seemed preferential to conservative approaches in terms of efficacy and was not significantly more expensive overall; but carries anaesthetic risk. There may be a clinically significant difference in outcome depending on management; however, more evidence is required to investigate this.

Post IORT seroma complication in breast cancer surgery

Background:

Intraoperative radiotherapy (IORT) has gained popularity over recent years due to its impact on shortening the radiotherapy treatment time for early breast cancer. It has certainly proven effective as an exclusive treatment or when combined with whole breast irradiation (WBIR). Seroma is a common non-life-threatening complication that may delay treatment and impose challenges on radiological diagnostic follow-up.

Aim:

To review and compare the occurrence of seroma in patients who received exclusive IORT or when combined with WBIR and to outline the diagnostic challenges encountered during radiological follow-up.

Materials and methods:

Based on strict selection criteria, all eligible patients who received IORT ± WBIR treatment between 2012 and 2019 in a university hospital setting were included. Demographic data, histological diagnosis, tumour size, tumour grade, lymphovascular invasion, nodal status, receptor status, treatment with neoadjuvant hormonal chemotherapy, applicator size, dose used, duration of radiotherapy treatment, timing of seroma development and duration of seroma were documented. Both clinical and radiological follow-up were exercised in all patients.

Results:

The total number of patients treated with breast conserving surgery (BCS) and IORT was 86. Age ranged between 31 and 75 years with the median age of 51 years. Patients treated exclusively with IORT were 39 (45%) while those who received the IORT as a boost were 47 (55%). Seroma was observed in 39(45%) of both IORT and IORT\WBIR patients. Those included 15(38%) of the exclusive IORT treated patients and 24 (62%) of those treated as a boost. Duration of asymptomatic seroma ranged from 6 months to 6 years. Repeated aspiration was performed in 2 (5%) patients. Postoperative seroma occurred independent of age histological diagnosis, tumour size, tumour grade, lymphovascular invasion, nodal status, receptor status, treatment with neoadjuvant hormonal\chemotherapy, applicator size, dose used or duration of radiotherapy treatment. All reviewed patients have shown increased risk of developing seroma; however, an increased incidence of seroma in the IORT + WBIR treated patients was higher than those who received exclusive IORT treatment.

Conclusion:

Postoperative seroma is a common non-life-threatening entity that occasionally may lead to delay in the subsequent treatment plan. IORT is a safe modality with many benefits; however, it may increase the risk of seroma formation independent of the clinical parameters. Promoting the expertise in post IORT breast imaging aids in overcoming diagnostic challenges.

[The effect of thoracic paravertebral block on seroma reduction in breast surgery - a randomized controlled trial]

BACKGROUND

Increasing number of patients are being operated because of breast cancer. Seroma is the most common problem that occurs after surgery that increases morbidity. For postoperative pain management, Thoracic Paravertebral Block (TPVB) has long been considered the gold standard technique. With performing TPVB, sympathetic nerves are also blocked.

OBJECTIVE

With this study, we aimed to search the effect of TPVB on seroma reduction in patients who undergo mastectomy and axillary node dissection surgery.

METHODS

Forty ASA I-II female patients aged 18-65, who were scheduled to go under elective unilateral mastectomy and axillary lymph node resection were included to the study. Patients were randomized into two groups as TPVB and control group. Ultrasound guided TPVB with 20 mL 0.25% bupivacaine was performed at T1 level preoperatively to the TPVB group patients. All patients were provided with i.v. patient-controlled analgesia device. Seroma formation amounts, morphine consumptions and Numeric Rating Scale (NRS) scores for pain were recorded 24^th hour postoperatively.

RESULTS AND CONCLUSIONS

Mean seroma formation at postoperative 24^th hour was 112.5±53.3 mL in the control group and 74.5±47.4 mL in the TPVB group (p=0.022). NRS scores were similar between two groups (p=0.367) at postoperative 24^th hour but mean morphine consumption at postoperative 24^th hour was 5.6±4 mg in the TPBV group, and 16.6±6.9 mg in the control group (p <0.001). TPVB reduces the amount of seroma formation while providing effective analgesia in patients who undergo mastectomy and axillary lymph node removal surgery.

Forty ASA I–II female patients aged 18–65, who were scheduled to go under elective unilateral mastectomy and axillary lymph node resection were included to the study. Patients were randomized into two groups as TPVB and Control group. Ultrasound guided TPVB with 20 mL 0.25% bupivacaine was performed at T1 level preoperatively to the TPVB group patients. All patients were provided with i.v. patient-controlled analgesia device. Seroma formation amounts, morphine consumptions and Numeric Rating Scale (NRS) scores for pain were recorded 24th hour postoperatively.

Results and conclusions

Mean seroma formation at postoperative 24th hour was 112.5 ± 53.3 mL in the control group and 74.5 ± 47.4 mL in the TPVB group (p = 0.022). NRS scores were similar between two groups (p = 0.367) at postoperative 24th hour but mean morphine consumption at postoperative 24th hour was 5.6 ± 4 mg in the TPBV group, and 16.6 ± 6.9 mg in the control group (p < 0.001). TPVB reduces the amount of seroma formation while providing effective analgesia in patients who undergo mastectomy and axillary lymph node removal surgery.

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.

A Prospective Study of Immediate Breast Reconstruction with Laser-Assisted Indocyanine Green Angiography

BACKGROUND

Complication rates following immediate breast reconstruction range from 4% to 60%. Mastectomy skin flap necrosis (MSFN) is often the sentinel event leading to secondary complications.

METHODS

All patients undergoing immediate reconstruction were enrolled. Upon mastectomy completion, the surgeon visually interpreted the skin flaps, performed laser-assisted indocyanine green angiography (LAIGA), and intervened if needed. Patients were followed for 90 days, documenting skin necrosis, infection, seroma, hematoma, implant loss, and reoperation.

RESULTS

There were 126 patients who had 206 immediate breast reconstructions. The complication rate was 22.3%. The incidence of MSFN was 14.1%. The reoperation rate was 8.7%. There was 1 necrosis-related implant loss. Postoperative surveys were completed on 193 breasts: 137 had visual and LAIGA interpretation of well or adequately perfused, resulting in 5.8% rate of necrosis, 2 reoperations, and no implant losses. Twenty breasts had visual and LAIGA interpretation of marginal or poor perfusion. Sixteen of these underwent intervention. The necrosis rate in this group was 35% with no implant losses. A third group with 26 breasts had adequate visual interpretation with marginal or poor perfusion on LAIGA. Ten breasts had no intervention, and 16 received intervention. The overall necrosis rate in this group was 42.3%, with 4 reoperations for necrosis and 1 implant loss.

CONCLUSIONS

LAIGA can more accurately predict complications from MSFN than surgeon assessment alone. When surgeon decision making is supplemented with LAIGA, it reduces the incidence of MSFN, infection, implant loss, and overall unexpected reoperation rate. LAIGA is a valuable adjunct for intraoperative decision making.

Two Exercise Schemes in Postoperative Breast Cancer: Comparison of Effects on Shoulder Movement and Lymphatic Disturbance

AIMS AND BACKGROUND

We attempted to determine the best method of performing the exercises in rehabilitation after breast cancer surgery and their influence on postoperative complications. Currently, there are no guidelines for these exercises. The scope of this study was to evaluate the effect of two schemes of physiotherapy exercises (directed or free) on shoulder function and lymphatic disturbance in postoperative rehabilitation.

SUBJECTS

Sixty women who underwent a modified radical mastectomy or quadrantectomy with axillary dissection were randomized into two groups.

METHODS

The physiotherapy technique used was kinesiotherapy. The directed group performed physiotherapy following a regimen of 19 exercises. The free group performed the exercises following the biomechanical physiological movements of the shoulder without a previously defined sequence or number of repetitions.

RESULTS

The averages of the flexion, abduction and external rotational movements of the shoulder showed better recovery with statistical significance in the directed group compared to the free group. There was no significant difference between the groups in lymphatic disturbance.

CONCLUSION

At the end of 42 days of follow-up, the movements of flexion, extension, abduction and external rotation of the shoulder were better rehabilitated in the directed group. The two schemes of exercises were not different with regard to lymphatic disturbance.

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.

Evaluation of the Quilting Technique for Reduction of Postmastectomy Seroma: A Randomized Controlled Study

Background. Postmastectomy seroma causes patients' discomfort, delays starting the adjuvant therapy, and may increase the possibility of surgical site infection. Objective. To evaluate quilting of the mastectomy flaps with obliteration of the axillary space in reducing postmastectomy seroma. Methods. A randomized controlled study was carried out among 120 females who were candidates for mastectomy and axillary clearance. The intervention group (N = 60) with quilting and the control group without quilting. All patients were followed up routinely for immediate and late complications. Results. There were no significant differences between the two groups as regards the demographic characteristics, postoperative pathological finding, and the immediate postoperative complications. The incidence of seroma was significantly lower in the intervention group compared with the control group (20% versus 78.3%, P < 0.001). Additionally, the intervention group had a shorter duration till seroma resolution (9 days versus 11 days, P < 0.001) and a smaller volume of drainage (710 mL versus 1160 mL, P < 0.001) compared with the control group. Conclusion. The use of mastectomy with quilting of flaps and obliteration of the axillary space is an efficient method to significantly reduce the postoperative seroma in addition to significantly reducing the duration and volume of wound drainage. Therefore we recommend quilting of flaps as a routine step at the end of any mastectomy.

[Quilting suture after mastectomy in prevention of postoperative seroma: a prospective observational study]

OBJECTIVES

The occurrence of a postoperative seroma is the main complication of mastectomy. In 2011, Ouldamer et al. adapted a quilting technique used in reconstructive surgery in mastectomy closure. The aim of this study is to evaluate the impact of quilting in the prevention of postoperative seroma.

PATIENTS AND METHODS

This is an observational prospective study to the Centre Hospital-University of Tours. Hundred and forty-four patients who underwent a mastectomy between January 1st, 2011 and October 1st, 2012 were included. Patients were divided into 2 groups, one with a classic wound closure with drainage and the second with quilting suture of skin flaps to the underlying musculature after mastectomy without drainage.

RESULTS

Quilting suture significantly reduces the postoperative seroma appearance (OR=0.15; CI95% [0.06-0.39]; P<0.001). Operative time is increased by 20minutes in the quilted group (P<0.001). Postoperative pain is not changed by quilting. The duration of hospitalization is significantly shorter (5.09±1.46 days versus 6.49±2.77 days; P<0.001). Quality of the healing and appearance of the scar, rated by patients, are identical in both groups.

CONCLUSION

Quilting is an effective method not only for prevention of seroma, but also for reducing of hospitalization duration, without increasing of postoperative pain and complications.

[Prevention of seroma post-mastectomy by surgical padding technique]

INTRODUCTION

Every year, 20,000 mastectomy are realized. The most common complication of these surgical procedure is seroma, occurring in a range of 10 to 85% of the cases, which may be responsible for an increased morbidity by complications: disunity of surgical flap, infection, and delay in administrating adjuvant therapies.

OBJECTIVE

We focused on a post-mastectomy padding technique, aiming at decreasing incidence of postoperative seromas.

PATIENTS AND METHODS

We conducted a retrospective study of patients treated with mastectomy from January 2012 to March 2014 in Amiens University Hospital. Forty-two patients were included: 20 to the "padding's" group and 22 to the "control's" group.

RESULTS

Drainage flow was significantly decreased at Day 1, Day 2, Day 3 and throughout hospitalization after padding (358.5mL versus 685mL; P=0.02). Hospital stays were significantly shortened by 2 days (5.3 versus 7.3 days; P<0.05) for patients receiving padding surgery.

DISCUSSION AND CONCLUSION

Our results show a benefit in the mastectomy padding flap. However, the retrospective character of our study and its strength character imply bias and data not available such as complications in type of wound dehiscence, pain, necrosis, the period from the establishment of the adjuvant therapies and aesthetic evaluation of technique. As such, we initiated a prospective randomized multicenter study late 2013, named PRELYMCA, which should be able to answer the pending questions.

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.

Prevention of seroma formation after axillary dissection--a comparative randomized clinical trial of three methods

Seroma is a frequent complication after breast cancer surgery. Closed suction drainage for several days is the standard procedure to reduce seroma formation. The aim of this study was to compare the efficacy of external compression dressing, suture flap fixation, and the conventional method of closed suction drains in the prevention of seroma formation. A total of 161 patients were prospectively randomized in a three groups × two subgroups design into control (n = 48), compression dressing (n = 53) and suturing groups (n = 49), and two subgroups, conventional drain removal (n = 75) and early drain removal (n = 75). All patients underwent ALND as part of MRM or BCT. The primary end point was the incidence of seroma. Suture flap fixation significantly reduced the incidence of seroma (p = 0.003), total drain output (p = 0.005), and duration of drainage (p = 0.001) without increase in wound complications. Compression dressing reduced duration of drainage significantly (p = 0.03), but not the total drain output (p = 0.15) or seromas (p = 0.58). Early drain removal on postoperative day 7 irrespective of drain output does not significantly increase seroma formation (p = 0.34) or wound complications. On multivariate analysis, BMI ≥ 30 (p = 0.02) and longer duration of drainage (p = 0.04) were identified as independent predictors for seroma formation. Obliteration of the dead space after breast cancer surgery by suture flap fixation is a safe and easy procedure, which significantly reduces postoperative seroma formation and duration of drainage. Compression dressing offers no advantage over normal dressing. Drains can be removed safely on postoperative day 7 irrespective of output without significant increase in complications.

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.

Vascular and cellular events in post-mastectomy seroma: an immunohistochemical study

This study aimed to describe the vascular and cellular histopathological changes that occurred in post-mastectomy seroma in an animal model. Unilateral mastectomies were conducted on 45 female albino rabbits. On day seven, the skin flap and the underlying tissues of the mastectomy regions were dissected and processed for histopathological examination using immunohistochemical staining of the T- and B-lymphocytes and macrophages (CD3, CD20, and CD68 respectively), and the vascular endothelia. The post-mastectomy regions in the seroma group showed a large number of inflammatory cells and newly formed blood vessels that lost the integrity of their endothelial cell linings, as revealed by the von Willebrand factor staining, as well the basement membrane, as revealed by the histochemical stain. The post-mastectomy seroma beds showed many CD3 and CD20+ve lymphocytes and CD68+ve macrophages. These macrophages were producing angiogenic factors, resulting in the persistent and continuous formation of new blood vessels. These new blood vessels were defective and represented an underlying cause of seroma formation.

Complications of Axillary Lymph Node Dissection in Treatment of Early Breast Cancer: A Comparison of MRM and BCS

ALND is part of primary management of breast cancer. In spite of complications it causes, its use in prognostication and planning adjuvant treatment in carcinoma breast is unquestioned. Prospective study was conducted on 100 patients of EBC [clinical stage I&II]. 50 underwent MRM, 50 WLE&AC. Patients were asked to rate on likert scale various symptoms on follow up. Multivariate regression analysis was carried out between pain, numbness, limitation of shoulder or arm motion, arm swelling, infection and age, BSA, clinical status of axilla, no. of LNs removed, no. of positive LNs, co-morbidities, chemotherapy, radiotherapy, hormone therapy, type of surgery. 60% patients reported one or more symptoms. Numbness, pain were reported by 39% each, arm swelling by 25%, limitation of arm movement by 16%, infection by 11%. Symptoms were mild in majority. On regression analyses numbness was associated with EBRT, co-morbidity, type of operation (p value- <0.01, <0.01, <0.05), pain had no significant association, swelling with EBRT, no. of LNs positive for metastases, co-morbidity, type of operation (p value- <0.01, <0.05, <0.05, <0.01), limitation of arm motion with no. of positive LNs (p value < 0.01), infection with no. of positive LNs, co-morbidity (p value <0.05, <0.05). There was no statistically significant difference in reporting of symptoms by patients in two groups. ALND caused morbidity in majority of patients but few reported severe symptoms and interference with daily activities.

A feasibility study of bevacizumab plus dose-dense doxorubicin-cyclophosphamide (AC) followed by nanoparticle albumin-bound paclitaxel in early-stage breast cancer

PURPOSE

Bevacizumab confers benefits in metastatic breast cancer but may be more effective as adjuvant therapy. We evaluated the cardiac safety of bevacizumab plus dose-dense doxorubicin-cyclophosphamide (ddAC) → nanoparticle albumin-bound (nab)-paclitaxel in human epidermal growth factor receptor 2 normal early-stage breast cancer.

EXPERIMENTAL DESIGN

Eighty patients with normal left ventricular ejection fraction (LVEF) were enrolled. Bevacizumab was administered for 1 year, concurrently with ddAC → nab-paclitaxel then as a single agent. LVEF was evaluated at months 0, 2, 6, 9, and 18. This regimen was considered safe if fewer than three cardiac events or fewer than two deaths from left ventricular dysfunction occurred. Correlative studies of cardiac troponin (cTn) and plasma renin activity (PRA) were conducted.

RESULTS

The median age was 48 years (range, 27-75 years), and baseline LVEF was 68% (53%-82%). After 39 months' median follow-up (5-45 months): median LVEF was 68% (53%-80%) at 2 months (n = 78), 64% (51%-77%) at 6 months (n = 66), 63% (48%-77%) at 9 months (n = 61), and 66% (42%-76%) at 18 months (n = 54). One patient developed symptomatic LV dysfunction at month 15. Common toxicities necessitating treatment discontinuation were hypertension (HTN, 4%), wound-healing complications (4%), and asymptomatic LVEF declines (4%). Neither cTn nor PRA predicted congestive heart failure (CHF) or HTN, respectively.

CONCLUSIONS

Bevacizumab with ddAC → nab-paclitaxel had a low rate of cardiac events; cTn and PRA levels are not predictive of CHF or HTN, respectively. The efficacy of bevacizumab as adjuvant treatment will be established in several ongoing phase III trials.

Effects of mastectomy on shoulder and spinal kinematics during bilateral upper-limb movement

BACKGROUND

Shoulder movement impairment is a commonly reported consequence of surgery for breast cancer.

OBJECTIVE

The aim of this study was to determine whether shoulder girdle kinematics, including those of the scapula, spine, and upper limb, in women who have undergone a unilateral mastectomy for breast cancer are different from those demonstrated by an age-matched control group.

DESIGN

An observational study using 3-dimensional kinematic analysis was performed.

METHODS

Women who had a unilateral mastectomy on their dominant-arm side (n=29, mean [+/-SD] age=62.4+/-8.9 years) or nondominant-arm side (n=24, mean [+/-SD] age=59.8+/-9.9 years), as well as a control group of age-matched women without upper-limb, shoulder, or spinal problems (n=22, mean [+/-SD] age=58.1+/-11.5 years), were measured while performing bilateral arm movements in the sagittal, scapular, and coronal planes. All of the women were free of shoulder pain at the time of testing. Data were collected from the glenohumeral joint, the scapulothoracic articulation, and the spine (upper and lower thoracic and lumbar regions) using an electromagnetic tracking system.

RESULTS

Women following mastectomy displayed altered patterns of scapular rotation compared with controls in all planes of movement. In particular, the scapula on the mastectomy side rotated upward to a markedly greater extent than that on the nonmastectomy side, and women following mastectomy displayed greater scapular excursion than controls.

CONCLUSIONS

The findings suggest that altered motor patterns of the scapula are associated with mastectomy on the same side. Whether these changes are harmful or not is unclear. Investigation of interventions designed to restore normal scapulohumeral relationships on the affected side following unilateral mastectomy for breast cancer is warranted.

Flap Anchoring Following Primary Breast Cancer Surgery Facilitates Early Hospital Discharge and Reduces Costs

BACKGROUND: Routine drain placement after breast cancer surgery is standard practice. Anchoring the axillary and mastectomy flaps to the underlying chest wall with sutures has been advocated as a means of avoiding drainage following breast surgery. This study compares outcomes following flap fixation or routine drain placement and uniquely considers the economic implications of each technique. PATIENTS AND METHODS: Data on seroma formation and wound infection following mastectomy and axillary clearance were recorded prospectively. Patients underwent either routine drain placement or flap anchoring using subcutaneous tacking sutures without drainage. Equipment and surgical bed costs were provided by our finance department. RESULTS: Data was available for 135 patients. 76 underwent flap anchoring without drainage and 59 had routine drainage. There was no difference in seroma rates between the two groups: 49% vs. 59% (p = 0.22). However, the length of hospital stay was reduced in the flap fixation group: 1.88 vs. 2.67 days (p < 0.0001). Per patient, flap suturing equated to an estimated financial saving of £ 240. CONCLUSIONS: Flap anchoring resulted in a significantly shorter hospital stay than routine drainage, with a comparable rate of seroma formation. This technique presents a viable alternative to drain placement and could lead to a considerable economic savings.

Prevention of seroma formation after mastectomy and axillary dissection by lymph vessel ligation and dead space closure: a randomized trial

INTRODUCTION

We aimed to reduce the incidence of seroma formation by altering surgical technique.

METHODS

Two hundred one breast cancer patients were randomly divided into 2 arms: arm 1 was operated on using an altered surgical technique, which is to ligate all of the tissue connecting axillary vein bundles to the specimen, to suture the anterior edge of the latissimus dorsi to the chest wall, and to fix the skin flap to the underlying muscle by subcutaneous sutures; arm 2 was operated on using the conventional technique.

RESULTS

The drainage volume, in the initial 3 days, for patients in arm 1 was significantly less than that for patients in arm 2 (P < .01). The duration of drainage in arm 1 was shorter than that in arm 2 (P < .01). The incidence of seroma formation in arm 1 (2%) was significantly less than that in arm 2 (14%) (P < .01).

CONCLUSION

The modified operating technique is an effective approach to reducing the incidence of seroma formation after mastectomy and axillary dissection.

Use of multiple drains after mastectomy is associated with more patient discomfort and longer postoperative stay

BACKGROUND

Seromas constitute a common complication following surgery for breast cancer, and closed drainage is used routinely to reduce its incidence. The aim of this study was to evaluate the influence of number of drains on patient discomfort, seroma formation, and hospital stay during the immediate postoperative period after mastectomy for breast cancer.

PATIENTS AND METHODS

Based on a retrospective review of our clinical database, 110 consecutive patients from January 2004 through January 2006 who had undergone a mastectomy and axillary clearance for breast cancer were sent a simple postal questionnaire for collection of data.

RESULTS

A total of 70 patients responded (all women; mean age, 69.4 +/- 11.4 years). Twenty-seven patients (38.57%) had 3 drains implanted unilaterally, 24 (34.28%) had 2, and 19 (27.14%) had 1 drain. They were divided into 2 groups: the first group with 1 drain (19 patients) and the other with 2 or 3 drains (51 patients). Median postoperative hospital stay was 2 days (range, 1-8 days); patients with 1 drain had a significantly shorter postoperative hospital stay (median, 2 days [range, 1-4 days] vs. 2 days [range, 1-8 days]; Mann-Whitney U test, P = .02). A total of 15 patients (21.43%) complained of a seroma. There was no difference in seroma rates between groups. Patients who had a single drain implanted had a significantly lower rate of discomfort (median, 2 [range, 1-5] vs. 3 [range, 1-7]; Mann-Whitney U test; P = .04).

CONCLUSION

The number of drains used after a mastectomy for breast cancer did not significantly affect the rate or amount of seromas in this study, but the use of a single drain after mastectomy was significantly associated with less discomfort and shorter postoperative hospital stay.

The effect of physiotherapy on shoulder function in patients surgically treated for breast cancer: a randomized study

The effect of physiotherapy on shoulder function in patients surgically treated for breast cancer was examined through a randomized controlled trial. One hundred and thirty-nine patients with newly diagnosed breast cancer were enrolled in the study. Sixty-two (45%) had Breast Conserving Therapy and 77 (55%) had Modified Radical Mastectomy (Axillary dissection of level I and II was included in both procedures). Enrolled patients were randomized to either group A or group B. Group A was offered, team instructed physiotherapy consisting of 12 sessions of 60 min, two sessions a week. The treatment was instituted between the sixth and eight postoperative week. Group B was also offered team instructed physiotherapy, consisting of 12 sessions of 60 minute two sessions a week, but not until the 26th postoperative week. The patients were seen for follow-up examinations four times during the first postoperative year (after 7, 13, 26 and 56 weeks). Shoulder function was assessed by the Constant Shoulder Score preoperatively and at the four follow-up examinations. Team instructed physiotherapy was found to improve the shoulder function significantly in patients treated surgically for breast cancer. The effect of the treatment was influenced by the type of surgery performed, and in mastectomised patients, also by the application of radiation therapy. Compromised shoulder function is a less frequent and less severe side effect to breast conserving therapy as compared to modified radical mastectomy.

Randomized clinical trial on the preservation of the medial pectoral nerve following mastectomy due to breast cancer: impact on upper limb rehabilitation

CONTEXT AND OBJECTIVE

Systematic modifications to the surgical technique of mastectomy have been proposed with the objective of minimizing injuries to the pectoral nerves and their effects. The aim of this study was to compare muscle strength and mass of the pectoralis major muscle (PMM) and abduction and flexion of the homolateral upper limb following mastectomy among women with breast cancer undergoing either preservation or sectioning of the medial pectoral nerve (MPN).

DESIGN AND SETTING

Randomized, double-blind, clinical trial on 30 women with breast cancer who underwent mastectomy between July 2002 and May 2003 in Campinas, Brazil.

METHODS

The women were allocated to a group, in which the MPN was preserved, or to another group in which it was sectioned. Fisher's exact and Wilcoxon tests were used to analyze the data, along with Friedman and ANOVA analysis of variance.

RESULTS

In the MPN preserved group, 81% of the women did not lose any PMM strength, compared with 31% in the sectioned MPN group (confidence interval, CI = 1.21; relative risk, RR = 2.14; P < 0.03). There were no differences between the groups regarding muscle mass (CI = 0.32; RR = 0.89; P = 0.8), shoulder abduction (CI = 1.36; RR = 0.89; P = 0.28) and shoulder flexion (CI = 1.36; RR = 1.93; P = 0.8).

CONCLUSIONS

Preservation of the MPN was significantly associated with maintenance of PMM strength, compared with nerve sectioning. No differences in muscle mass or in abduction and flexion of the homolateral shoulder were found between the groups.

Shoulder disability and late symptoms following surgery for early breast cancer

INTRODUCTION

Axillary dissection in combination with radiation therapy is thought to be the main reason why patients surgically treated for breast cancer may develop decreased shoulder mobility on the operated side. The surgery performed on the breast has not been ascribed any considerable importance. In order to evaluate the influence of the surgical technique and the adjuvant oncological therapy on the development of shoulder morbidity, we assessed the physical disability in 132 breast cancer patients with a median follow-up time of 3 years after surgery.

METHODS AND METHODS

Eighty nine (67%) patients had been subjected to modified radical mastectomy and 43 (33%) to breast conserving therapy (BCT). All patients had axillary dissection of level I and II. The shoulder function was assessed by the Constant Shoulder Score including both subjective parameters on pain and ability to perform the normal tasks of daily living, and objective parameters assessing active range of motion and muscle strength.

RESULTS

Shoulder disability seems to be a frequent late complication to the treatment of early breast cancer (35%). When equal axillary dissection and radiation therapy had been applied, BCT patients were found to suffer less frequent from this complication than patients treated with mastectomy.

Concepts of seroma formation and prevention in breast cancer surgery

BACKGROUND

Seroma formation is the commonest early sequel to breast cancer surgery especially when axillary dissection is undertaken. It is associated with significant morbidity and financial burden. The main pathophysiology of seroma is still poorly understood and remains controversial. The optimal ways to reduce the incidence of seroma formation are unknown. The aim of this paper is to review the concepts of pathophysiology of seroma formation following mastectomy and breast-conserving surgery for cancer. The various techniques in practice to reduce its incidence and treatment are outlined.

METHOD

MEDLINE search of published work on the subject with respect to its pathophysiology, prevention and treatment was carried out. Manual retrieval of relevant articles in the reference lists of the original papers from the MEDLINE was then carried out.

RESULT

The pathophysiology and mechanism of seroma formation in breast cancer surgery remains controversial and not fully understood. Methods of prevention and treatment of seroma remain varied and inconclusive.

CONCLUSION

Evidence suggests an increase in the incidence of seroma because of thermal trauma from electrocautery dissection, but this is indispensable for surgical haemostasis. Obliteration of dead space by various flap apposition techniques has been shown to be advantageous in reducing incidence and volume of seroma. Low-pressure suction drainage reduces seroma volume and duration of drainage leading to earlier drain removal. Preventive measures have to be tailored according to individual patient and operative factors.

T2 Contributions to the Brachial Plexus

Objective:

Recent advancements in neurotization and nerve grafting procedures have led to an increasing need for knowledge of the detailed anatomy of communicating branches between peripheral nerves. Although the surgical anatomy of the axilla has been well described, little is known regarding the degree or frequency of potential contributions to or communications with the brachial plexus. The aim of our study, therefore, was to explore extrathoracic, as well as potential intrathoracic, contributions to the brachial plexus from T2.

Methods:

The anatomy of the ventral primary ramus of T2 and the second intercostal nerve, including its lateral cutaneous contribution as the intercostobrachial nerve, was examined in 75 adult human cadavers (150 axillae), with particular emphasis on the communications with the brachial plexus.

Results:

Extrathoracically, communications were observed to occur in 86% of specimens. These contributions arose variably from either the intercostobrachial nerve or one of its branches and communicated with the medial cord (35.6%), medial ante-brachial cutaneous nerve (25.5%), or posterior antebrachial cutaneous nerve (24%). Whereas the majority of specimens (68.2%) were observed to have only one extratho-racic communication, 31.7% of specimens exhibited two. Intrathoracically, communications were observed to occur in 17.3% of specimens. These communications always arose from the ventral primary ramus of T2. When combining and comparing data within individual specimens, it was observed that those axillae without an extratho-racic contribution from the intercostobrachial nerve always contained an intrathoracic communication.

Conclusion:

Based on our findings, we conclude that 100% of specimens contained a communication branch between T2 and the brachial plexus. Considering the possible implications of this data, with regards to sensory innervation of the arm and axilla, further studies in this area of research could prove extremely beneficial.

Breast Cancer-Related Lymphedema ? What Are the Significant Predictors and How They Affect the Severity of Lymphedema?

According to the American Cancer Society, there are currently 2 million breast cancer (BC) survivors in the USA and 20% of them cope with lymphedema (LE). The primary aim of this study was to determine the predictive factors of BC-related LE. The secondary aim was to investigate the impact of predictors on the severity of LE. The study design was intended to be a 1:2 matched case-control study. Instead, we stratified on age (+/-10 years), radiation therapy (y/n), and type of operation (SM/MRM/MRM with tram). Patients who underwent BC surgery between 1990 and 2000 at UPMC Magee-Womens Hospital were reviewed for LE. Data were collected on 52 women with LE and 104 female controls. Logistic regression was utilized to assess the relationship between risk factors and LE. Ordinal logistic regression was performed to determine the association between risk factors and severity of LE. Severity was defined according to the volume difference between affected and unaffected limbs. Risk factors considered were occupation/hobby (hand use), TNM stage, number of dissected nodes, number of positive nodes, tumor size, infection, allergy, diabetes mellitus, hypertension, hypothyroidism, chronic obstructive pulmonary disease, and body mass index (BMI). LE was mild in 43 patients and was moderate/severe in nine patients. The level of hand use in the control group was categorized as low in 56 (54%), medium in 15 (14%), and high in 33 (32%) patients. The corresponding frequencies were 14 (33%), 6 (14%) and 23 (53%) for patients with mild LE and 3 (33%), 1 (11%), 5 (56%) for patients with moderate/severe LE (p < 0.05). Infection of the operated side arm was reported by two (2%) patients in the control group, 14 (33%) patients with mild LE and five (56%) patients with moderate/severe LE (p < 0.05). The mean BMI was 26.1 kg/m(2) (SD 4.9) for the control group, 29.0 kg/m(2) (SD 5.9) for the mild LE group and 30.9 kg/m(2) (SD 7.5) for patients with moderate/severe LE (p < 0.05). The results of this stratified case-control study demonstrated that the risk and severity of LE was statistically related to infection, BMI, and level of hand use.

Effect of mechanical closure of dead space on seroma formation after Breast surgery

Seroma, a collection of serous fluid, is the most common problem after breast surgery. The aim of this study was to review the effect of mechanical closure of dead space on seroma formation after breast surgery. There are two mechanical methods for closure of the dead space beneath skin flaps: compression by external pressure, and fixation of the flaps with sutures. There is no evidence to suggest that the routine use of a pressure garment or compression dressing is beneficial. However, it appears that suture flap fixation does reduce seroma formation, simplify postoperative care and dressing, and thus allow early removal of drains and discharge. Drains are helpful for mechanical closure of dead space, but in breast-conserving surgery this technique may preclude the use of a drain. However, previous studies have often been small in scale and poor in quality. Further studies should examine the effect of this technique on quality of life, cosmesis, and medical economics.

Evidence-Based Risk Factors for Seroma Formation in Breast Surgery

BACKGROUND

Seroma is a common problem in breast surgery. The aim of this systematic review was to identify risk factors for seroma formation.

METHODS

Articles published in English were obtained from searches of Medline and additional references were found in the bibliographies of these articles. Risk factors were graded according to the quality and strength of evidence and to the direction of association.

RESULTS

One meta-analysis, 51 randomized controlled trials, 7 prospective studies and 7 retrospective studies were identified. There was no risk factor supported by strong evidence, but there was moderate evidence to support a risk for seroma formation in individuals with heavier body weight, extended radical mastectomy as compared with simple mastectomy, and greater drainage volume in the initial 3 days. On the other hand, the following factors did not have a significant influence on seroma formation: duration of drainage; hormone receptor status; immobilization of the shoulder; intensity of negative suction pressure; lymph node status or lymph node positivity; number of drains; number of removed lymph nodes; previous biopsy; removal of drains on the fifth postoperative day versus when daily drainage volume fell to minimal; stage; type of drainage (closed suction versus static drainage); and use of fibrinolysis inhibitor. In contrast, sentinel lymph node biopsy reduced seroma formation. Evidence was weak, or unproven, for other factors that were commonly cited in the literature.

CONCLUSIONS

Although a number of factors have been correlated with seroma formation, strong evidence is still scarce. However, there is evidence showing that sentinel lymph node biopsy reduces seroma formation.
