Wound complications after modified radical mastectomy compared with tylectomy with axillary lymph node dissection

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.

Analysis of factors influencing postoperative drainage time in breast cancer

BACKGROUND

To investigate the related factors affecting the postoperative indwelling time of drainage tubes (hereinafter referred to as drainage time) in breast cancer (BC) and evaluate the effect of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) preparation on reducing postoperative drainage time.

METHODS

The clinical data of 165 BC patients in our hospital, including the postoperative drainage time and occurrence of seroma and related complications (such as fever, incision infection, and flap necrosis) after extubation, were retrospectively analyzed. Univariate, multivariate, and stratified analyses were used to determine the correlations between 15 factors including age, body weight, body mass index (BMI), and PA-MSHA preparation, and the postoperative total drainage volume and drainage time.

RESULTS

Age, BMI, and PA-MSHA preparation were independent factors affecting the postoperative drainage volume and drainage time of BC patients. Age and BMI were positively correlated with postoperative drainage volume and drainage time (P≤0.004, P≤0.037). PA-MSHA preparation significantly reduced the postoperative total drainage volume and drainage time (P<0.001), decreased the incidence of seroma after extubation (P=0.024), and did not increase complications (P>0.05).

CONCLUSIONS

Obese and elderly patients were at a significantly high risk of a high drainage volume and long drainage time. Local treatment with PA-MSHA preparation had the advantages of reducing postoperative drainage volume, reducing drainage time, preventing seroma, and not increasing complications, and was a safe and effective treatment. For BC patients aged over 60 years and with a BMI ≥25, the intraoperative local spraying of wounds with PA-MSHA preparation to reduce postoperative drainage times is a valuable option.

Breast Surgery: Management of Postoperative Complications Following Operations for Breast Cancer

Breast cancer surgery is associated with low rates of surgical morbidity. Postoperative complications related to breast surgery include seroma, infection, hematoma, mastectomy flap necrosis, wound dehiscence, persistent postsurgical pain, Mondor disease, fat necrosis, reduced tactile sensation after mastectomy, and venous thromboembolism. Postoperative complications related to axillary surgery include seroma, infection, lymphedema, nerve injury, and reduced shoulder/arm mobility. The overall rate of complication related to axilla surgery may be confounded by the type of breast surgery performed. The management of postoperative complications related to oncologic breast and axillary surgery independent of reconstruction is reviewed here.

Comparisons of postoperative outcomes after breast cancer surgery in patients with and without renal replacement therapy: a matched-pair cohort study using a Japanese nationwide inpatient database

BACKGROUND

Although patients receiving renal replacement therapy (RRT) have more comorbidities and higher mortality and morbidity risks than the general population, surgery during breast cancer treatment is crucial because of limitations in anticancer agents for patients with renal insufficiency. We aimed to compare the short-term postoperative outcomes between patients with and without RRT.

METHODS

Patients who underwent surgery for stages 0-III breast cancer between July 2010 and March 2017 were retrospectively identified in a Japanese nationwide inpatient database and divided into those with RRT (RRT group, n = 1547) and those without RRT (control group, n = 364,047). We generated a 1:4 matched-pair cohort matched for age, institution, and fiscal year at admission. We conducted multivariable regression analyses to compare postoperative complications, 30-day readmission, and anesthesia duration between the two groups.

RESULTS

The RRT group was more likely to have comorbidities (95.0% vs. 24.1%) and undergo total mastectomy (64.2% vs. 47.0%) than the control group. The RRT group was not significantly associated with complications (odds ratio 1.18; 95% confidence interval [CI] 0.89-1.56) and 30-day readmission (odds ratio 0.88; 95% CI 0.65-1.18), but was associated with shorter anesthesia duration (difference, - 6.8 min; 95% CI - 10.7 to - 3.0 min) compared with the control group.

CONCLUSIONS

The matched-pair cohort analyses revealed no significant differences in postoperative complications after breast cancer surgery between patients with and without RRT. Breast cancer surgery in patients with RRT may be as safe as that in patients without RRT, if comorbidities other than chronic renal failure are adequately addressed.

Impact of Body Mass Index on Outcomes After Breast Cancer Surgery: Nationwide Inpatient Database Study in Japan

BACKGROUND

Recent studies have shown better postoperative outcomes in mildly obese patients, a phenomenon called the obesity paradox. In the field of breast cancer surgery, however, previous studies have only shown an association between obesity and worse postoperative outcomes using multivariable analysis; the obesity paradox has not been investigated in patients undergoing breast cancer surgery.

PATIENTS AND METHODS

We identified patients who underwent mastectomy for stage 0 to III breast cancer from July 2010 to March 2017 using a Japanese nationwide inpatient database. We used restricted cubic spline analyses to investigate potential nonlinear associations between body mass index (BMI) and outcomes (postoperative complications, 30-day readmission, duration of anesthesia, length of hospital stay, and hospitalization costs). We also performed multivariable regression analyses for the outcomes.

RESULTS

Among 239,108 eligible patients, 25.6% had a BMI of > 25.0 kg/m². BMI showed U-shaped associations with postoperative complications, length of stay, and hospitalization costs, and a linear association with duration of anesthesia. The proportion of postoperative complications was lowest at a BMI of around 22.0 kg/m², while the length of stay was shortest and total costs were lowest at a BMI of around 20.0 kg/m². Compared to a BMI of 22.0 kg/m², a BMI of > 30.0 kg/m² was significantly associated with greater postoperative complications, 30-day readmission, duration of anesthesia, length of stay, and hospitalization costs.

CONCLUSION

Restricted cubic spline analyses displayed U-shaped associations between BMI and in-hospital complications, length of stay, and hospitalization costs, but none of the associations showed the obesity paradox.

Impact of contemporary therapy- concepts on surgical morbidity in breast cancer patients: A retrospective single center analysis of 829 patients

INTRODUCTION

Morbidity after breast cancer surgery remains low with revision surgery below 5%. This retrospective monocentric study investigates whether new methods like neoadjuvant chemotherapy (nCT), oncoplastic surgery (OPS) or intraoperative radiotherapy (IORT) affect overall morbidity. In addition, we sought to determine a possible effect of morbidity on oncologic outcome.

METHODS

Clinical Data from all breast cancer cases, operated at the OnkoZert"- certified Breast Health Center of the "Sisters of Charity Hospital" in Linz between 2011 and 2014, were evaluated. Age (≤/>70), nCT, IORT, surgical technique and histological subtypes were analyzed concerning their impact on morbidity. Overall survival (OS) and disease-free survival (DFS) were assessed by Kaplan-Meier estimates.

RESULTS

829 patients were included, 24% were older than 70y, 19% underwent oncoplasty, 5.5% immediate reconstruction, 17% of the invasive cancers were treated with nCT and 4.1% received IORT. One or more complications occurred in 83 patients (10%), while 62 patients (7.5%) underwent revision surgery. Univariate analysis showed that mastectomy and age >70 doubled the risk of surgical morbidity. Multivariate regression analysis identified age >70 as the only independent prognostic parameter for the occurrence of morbidity (OR: 2.42, 95% CI: 1.41-4.1, p = 0,00134). Morbidity was not associated with worse oncologic outcome in terms of OS or DFS.

SUMMARY

In our patient collective, modern techniques such as nCT, OPS or IORT did not influence surgical morbidity rates. Those were only increased by patient's age. Additionally, surgical morbidity did not show any significant impact on OS and DFS.

Comparison of harmonic scalpel and conventional technique in the surgery for breast cancer: A systematic review and meta-analysis

BACKGROUND

Harmonic scalpel is considered as a promising surgical tool for breast cancer, while its advantage over conventional approach is still controversial. Therefore, we performed this meta-analysis to compare the outcomes of harmonic scalpel and conventional tools in the surgery for breast cancer.

MATERIALS AND METHODS

Studies reporting the outcomes of harmonic scalpel and conventional technologies were systematically searched from online databases, PubMed and EMBASE up to April 30, 2018. Data were presented as odds ratio, risk ratio (RR), and mean difference (MD) with 95% confidence interval (CI).

RESULTS

Intraoperative blood loss (I² = 96%, P < 0.05, MD = -68.78, 95% CI -93.31 to -44.24), seroma (I² = 3%, P = 0.41, RR = 0.63, 95% CI 0.46-0.86) and hematoma formation (I² = 0%, P = 0.64, RR = 0.41, 95% CI 0.23-0.73), drainage volume (I² = 89%, P < 0.05, MD = -105.33, 95% CI -161.33 to -49.33) and time (I² = 93%, P < 0.05, MD = -2.18, 95% CI -3.75 to -0.61), necrosis (I² = 35%, P = 0.20, RR = 0.37, 95% CI 0.16-0.86), surgical duration (I² = 79%, P < 0.05, MD = -8.49, 95% CI -16.56 to -0.43), and hospital stay (I² = 97%, P < 0.05, MD = -0.94, 95% CI -1.74 to -0.14) are significantly different between the two groups.

CONCLUSIONS

Harmonic scalpel is superior to conventional tools in terms of decreasing intraoperative blood loss, seroma and hematoma formation, drainage volume and time, necrosis prevalence, surgical duration, and hospital stay, which should be strongly recommended in the surgery for breast cancer.

Impact of Diabetes on 30-Day Complications in Mastectomy and Implant-Based Breast Reconstruction

BACKGROUND

Diabetic patients are known to be at increased risk of postoperative complications after multiple types of surgery. However, conflicting evidence exists regarding the association between diabetes and wound complications in mastectomy and breast reconstruction. This study evaluates the impact of diabetes on surgical outcomes after mastectomy procedures and implant-based breast reconstruction.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database review from 2010 to 2015 identified patients undergoing total, partial, or subcutaneous mastectomy, as well as immediate or delayed implant reconstruction. Primary outcomes included postoperative wound complications and implant failure. Preoperative variables and outcomes were compared between diabetic and nondiabetic patients. Multivariate regression was used to control for confounders.

RESULTS

The following groups were identified: partial (n = 52,583), total (n = 41,540), and subcutaneous mastectomy (n = 3145), as well as immediate (n = 4663) and delayed (n = 4279) implant reconstruction. Diabetes was associated with higher rates of superficial incisional surgical site infection (SSI) in partial mastectomy (odds ratio [OR] = 8.66; P = 0.03). Diabetes was also associated with higher rates of deep incisional SSI (OR = 1.61; P = 0.01) in subcutaneous mastectomy and both superficial (OR = 1.56; P = 0.04) and deep incisional SSI (OR = 2.07; P = 0.04) in total mastectomy. Diabetes was not associated with any wound complications in immediate reconstruction but was associated with higher rates of superficial incisional SSI (OR = 17.46; P < 0.001) in the delayed reconstruction group. There was no association with implant failure in either group.

CONCLUSIONS

Evaluation of the largest national cohort of mastectomy and implant reconstructive procedures suggests that diabetic patients are at significantly increased risk of 30-d postoperative infectious wound complications but present no difference in rates of early implant failure.

Closed Incision Negative Pressure Therapy in Oncological Breast Surgery: Comparison with Standard Care Dressings

Background:

Negative pressure wound therapy was developed for treating wounds associated with unfavorable healing factors. The principles of the negative pressure wound therapy applied on clean and closed surgical incision originate the closed incision negative pressure therapy (ciNPT). We evaluated the use of ciNPT in the setting of oncological breast surgery.

Methods:

From January 1, 2015, to June 31, 2015, we prospectively selected 37 patients undergoing oncological breast surgery with a minimum of 4 risk factors. Seventeen patients (25 surgeries) voluntary tested ciNPT (ciNPT sample), whereas the remaining 20 (22 surgeries) chose conventional postsurgery dressing (Standard Care sample). Follow-up controls to evaluate postsurgical complications were performed on days 7, 14, 30, and 90. At 12 months, the quality of life, scar, and overall aesthetic outcomes were evaluated with specific questionnaires filled in by surgeon and patient. The Standard Care sample was investigated on risk factors associated with poor healing.

Results:

The ciNPT sample showed a significant prevalence of high risk factors, especially extensive undermining and bilateral surgeries, and a predominance of women under 65 years; only 1/25 (4%) surgical procedures was followed by complications. In the Standard Care sample, 10 of 22 surgeries (45%) were followed by complications. The difference in complication rate between the 2 samples was significant. The BIS (Body Image Scale) scores suggested that most patients were satisfied with their body image regardless of the type of dressing. All other questionnaire scores clearly vouched for a significant superiority of the ciNPT. Previous surgery ≤ 30 days emerged as the surgery-related high risk factor most frequently associated with postsurgery complications.

Conclusion:

The results of our study support the use of ciNPT in oncological breast surgery: it showed to be a well-tolerated, adaptable, and reliable dressing capable of reducing postsurgical complications and improving scar outcomes in patients presenting with high risk factors.

Risk and predictors of psoriasis in patients with breast cancer: a Swedish population-based cohort study

BACKGROUND

The risk of psoriasis in patients with breast cancer is largely unknown, as available evidence is limited to case findings. We systematically examined the incidence and risk factors of psoriasis in patients with breast cancer.

METHODS

A Swedish nationwide cohort of 56,235 breast cancer patients (2001-2012) was compared to 280,854 matched reference individuals from the general population to estimate the incidence and hazard ratio (HR) of new-onset psoriasis. We also calculated HRs for psoriasis according to treatment, genetic, and lifestyle factors in a regional cohort of 8987 patients.

RESULTS

In the nationwide cohort, 599 patients with breast cancer were diagnosed with psoriasis during a median follow-up of 5.1 years compared to 2795 cases in the matched reference individuals. This corresponded to an incidence rate of 1.9/1000 person-years in breast cancer patients vs. 1.7/1000 person-years in matched reference individuals. Breast cancer patients were at an increased risk of psoriasis (HR = 1.17; 95% confidence interval (CI) = 1.07-1.28), especially its most common subtype (psoriasis vulgaris; HR = 1.33; 95% CI = 1.17-1.52). The risk of psoriasis vulgaris was highest shortly after diagnosis but remained increased up to 12 years. Treatment-specific analyses indicated a higher risk of psoriasis in patients treated with radiotherapy (HR = 2.44; 95% CI = 1.44-4.12) and mastectomy (HR = 1.54, 95% CI = 1.03-2.31). Apart from treatment-specific effects, we identified genetic predisposition, obesity, and smoking as independent risk factors for psoriasis in breast cancer patients.

CONCLUSIONS

The incidence of psoriasis is slightly elevated among patients with breast cancer, with treatment, lifestyle, and genetic factors defining the individual risk profile.

Comparison of electrocautery and plasmablade on ischemia and seroma formation after modified radical mastectomy for locally advanced breast cancer

The aim of this study was to compare postoperative drainage volumes and IMA levels in patients who underwent modified radical mastectomy (MRM) with using PlasmaBlade (PB) or electrocautery (EC). A total of 36 patients who underwent MRM with PB or EC in our clinic between August 2012 to February 2013 were enrolled. Number of removed and positive lymph nodes, duration of drainage and total drainage volume was recorded. Seroma formation after drain removal and number of aspirations were also recorded. Serum ischemia modified albümine (IMA) levels were analysed before surgery, 1 hour and 24 hour after surgery. In total, 36 patients were treated with MRM in the study period. Of the 36 patients, 16 underwent MRM with PB, and 20 underwent MRM with EC. The patients demographics were similar in both groups. The mean drainage volume and seroma formation were significantly higher in the PB group when compared with EC group (P<0.05). Number of aspirations due to the seroma were also high in PB group. The total aspiration volume of seroma was not different in both groups. IMA levels 24 hours after surgery in the PB group was significantly higher than EC group. There was no statistical significance between the groups for IMA levels at 1st hour. PB is a monopolar energy device and is associated with increased levels of ischemia. This situation resulted with an increased volume of total axillary drainage and elevated risk of seroma formation.

A systematic review and meta-analysis of Harmonic technology compared with conventional techniques in mastectomy and breast-conserving surgery with lymphadenectomy for breast cancer

BACKGROUND

Mastectomy and breast-conserving surgery (BCS) are important treatment options for breast cancer patients. A previous meta-analysis demonstrated that the risk of certain complications can be reduced with the Harmonic technology compared with conventional methods in mastectomy. However, the meta-analysis did not include studies of BCS patients and focused on a subset of surgical complications. The objective of this study was to compare Harmonic technology and conventional techniques for a range of clinical outcomes and complications in both mastectomy and BCS patients, including axillary lymph node dissection.

METHODS

A comprehensive literature search was performed for randomized controlled trials comparing Harmonic technology and conventional methods in breast cancer surgery. Outcome measures included blood loss, drainage volume, total complications, seroma, necrosis, wound infections, ecchymosis, hematoma, hospital length of stay, and operating time. Risk of bias was analyzed for all studies. Meta-analysis was performed using random-effects models for mean differences of continuous variables and a fixed-effects model for risk ratios of dichotomous variables.

RESULTS

Twelve studies met the inclusion criteria. Across surgery types, compared to conventional techniques, Harmonic technology reduced total complications by 52% (P=0.002), seroma by 46% (P<0.0001), necrosis by 49% (P=0.04), postoperative chest wall drainage by 46% (P=0.0005), blood loss by 38% (P=0.0005), and length of stay by 22% (P=0.007). Although benefits generally appeared greatest in mastectomy patients with lymph node dissection, Harmonic technology showed significant reductions in complications in the BCS study subgroup.

CONCLUSION

In this meta-analysis of both mastectomy and BCS procedures, the use of Harmonic technology reduced the risk of most complications by about half across breast cancer surgery patients. These benefits may be due to superior hemostatic capabilities of Harmonic technology and better dissection, particularly lymph node dissection. Reduction in complications and other resource outcomes may engender lower downstream health care costs.

Risk Factors for Complications Differ Between Stages of Tissue-Expander Breast Reconstruction

BACKGROUND

Tissue-expander (TE) placement followed by implant exchange is currently the most popular method of breast reconstruction. There is a relative paucity of data demonstrating patient factors that predict complications specifically by stage of surgery. The present study attempts to determine what complications are most likely to occur at each stage and how the risk factors for complications vary by stage of reconstruction.

METHODS

A retrospective chart review was performed on all 1275 patients who had TEs placed by the 2 senior authors between 2004 and 2013. Complication rates were determined at each stage of reconstruction, and these rates were further compared between patients who had pre-stage I radiation, post-stage I radiation, and no radiation exposure. Multivariate logistic regression was used to identify independent predictors of complications at each stage of reconstruction.

RESULTS

A total of 1639 consecutive TEs were placed by the senior authors during the study period. The overall rate for experiencing a complication at any stage of surgery was 17%. Complications occurred at uniformly higher rates during stage I for all complications (92% stage I vs 7% stage II vs 1% stage III, P < 0.001). Predictors of stage I complications included increased body mass index [odds ratio (OR), 1.04; 95% confidence interval (CI), 1.01-1.07], current smoking status (OR, 3.0; 95% CI, 1.7-4.8), and higher intraoperative percent fill (OR, 3.3; 95% CI, 1.7-6.3). Post-stage I radiation was the only independent risk factor for a stage II complication (OR, 4.5; 95% CI, 1.4-15.2).

CONCLUSIONS

Complications occur at higher rates after stage I than after stage II, and as expected, stage III complications are exceedingly rare. Risk factors for stage I complications are different from risk factors for stage II complications. Body mass index and smoking are associated with complications at stage I, but do not predict complications at stage II surgery. The stratification of risk factors by stage of surgery will help surgeons and patients better manage both risk and expectations.

Pretreatment health measures and complications after surgical management of elderly women with breast cancer

BACKGROUND

Elderly patients with breast cancer are less likely to be offered surgery, partly owing to co-morbidities and reduced functional ability. However, there is little consensus on how best to assess surgical risk in this patient group.

METHODS

The ability of pretreatment health measures to predict complications was investigated in a prospective cohort study of a consecutive series of women aged at least 70 years undergoing surgery for operable (stage I-IIIa) breast cancer at 22 English breast units between 2010 and 2013. Data on treatment, surgical complications, health measures and tumour characteristics were collected by case-note review and/or patient interview. Outcome measures were all complications and serious complications within 30 days of surgery.

RESULTS

The study included 664 women. One or more complications were experienced by 41·0 per cent of the patients, predominantly seroma or primary/minor infections. Complications were serious in 6·5 per cent. More extensive surgery predicted a higher number of complications, but not serious complications. Older age did not predict complications. Several health measures were associated with complications in univariable analysis, and were included in multivariable analyses, adjusting for type/extent of surgery and tumour characteristics. In the final models, pain predicted a higher count of complications (incidence rate ratio 1·01, 95 per cent c.i. 1·00 to 1·01; P = 0·004). Fatigue (odds ratio (OR) 1·02, 95 per cent c.i. 1·01 to 1·03; P = 0·004), low platelet count (OR 4·19, 1·03 to 17·12: P = 0·046) and pulse rate (OR 0·96, 0·93 to 0·99; P = 0·010) predicted serious complications.

CONCLUSION

The risk of serious complications from breast surgery is low for older patients. Surgical decisions should be based on patient fitness rather than age. Health measures that predict surgical risk were identified in multivariable models, but the effects were weak, with 95 per cent c.i. close to unity.

Ultrasonic shears versus electrocautery in axillary dissection for breast cancer-a randomized controlled trial

Theoretical advantages of use of Ultrasonic shears include less tissue damage and better sealing of lymphatic vessels. This may play a role in reducing prolonged drainage following axillary dissection for breast cancer. We conducted a prospective randomized controlled study to evaluate efficacy of ultrasonic shears over cautery for axillary dissection. Between April 2011 and April 2013, 92 patients were randomized to undergo axillary dissection with either ultrasonic shears (n = 46) or electrocautery (n = 46). Primary endpoints were time till drain removal and cumulative axillary drainage. Categorical data were compared by Pearson's chi-squared test. Continuous variables were compared by Independent t test or Mann Whitney U test. Data was analyzed using SPSS version 18.0. Both groups were comparable with respect to clinical and pathologic characteristics. Clinical characteristics of mean age, body mass index, side of tumor, neoadjuvant chemotherapy, and type of surgery (breast conservation or mastectomy) were similar. Pathologic variables (weight of specimen, number of lymph nodes harvested, pathologic T and N status, as well as grade of tumor) were also comparable among the two groups. There was no statistically significant difference in either primary endpoint of time till drain removal (15 vs. 14.5 days, p = 0.73) or cumulative axillary drainage (1,260 vs. 1,086.5 ml, p = 0.79). Patient and disease characteristics among the two groups were similar. But, there was no difference in either primary endpoint of cumulative axillary drainage or time to drain removal. We conclude that there is no advantage to use of ultrasonic shears over cautery in reducing drainage following axillary dissection for breast cancer.

Standardization of morbidity assessment in breast cancer surgery using the Clavien Dindo Classification

INTRODUCTION

There are no published data on standardized scoring systems for morbidity after breast cancer surgery. Aim of the study was to establish the Clavien Dindo Classification (CDC) as assessment tool and to identify risk factors for morbidity after breast surgery investigating new techniques including oncoplastic surgery and neoadjuvant chemotherapy.

PATIENTS AND METHODS

Between 2008 and 2010, data were retrospectively evaluated from 485 women with breast cancer who underwent surgery at a university hospital. The CDC was used to assess the severity of postoperative complications. Multivariable analyses were adjusted by body-mass index, smoking, diabetes mellitus and tumour size.

RESULTS

Overall complications (CDC 1-4) were reported in 28.7%. Second surgery related to major complications (CDC 3-4) was mandatory in 4.7%. Axillary dissection was an independent predictor for CDC 1-4 in all patients (P = 0.008, OR of 1.81, 95%CI 1.17-2.82). We found no independent predictor for CDC 3-4. Oncoplastic surgery increased the rate of wound infections (P = 0.010, OR: 2.94, 95%CI 1.30-6.67) and necroses (P < 0.001, OR: 8.38, 95%CI 3.28-21.4). Axillary dissection elevated wound infection (P = 0.040, OR: 2.07, 95%CI 1.03-4.14) and seroma rates (P < 0.001, OR: 2.46, 95%CI 1.51-4.01). Neoadjuvant chemotherapy had no impact on morbidity.

CONCLUSION

The CDC is a valid assessment tool for future clinical trials and may be useful for hospital quality control. While axillary dissection and oncoplastic surgery raised morbidity, no single factor predicted for morbidity related second surgery.

Infections associated with solid malignancies

Although solid tumors comprise the vast majority of cancers, the incidence of serious infectious complications in this population is much less than in patients with hematologic malignancies. Most infections involving patients with solid tumors comprise two groups. First, patients acquire infections as a result of the cancer itself, due to either mass effect that interrupts normal function or destruction of the normal barriers to infection. Second, patients acquire infections as a complication of the treatments they receive, such as chemotherapy, radiation, surgery, or medical devices. Advances in the management of cancer have resulted in a gradual stepwise improvement in survival for patients with most types of solid tumors. Much of this improvement has been attributed to advances in cancer screening, diagnosis, and therapeutic modalities. In addition, improvements in the prevention, diagnosis, and treatment of infections have likely contributed to this prolonged survival. This review highlights select articles in the medical literature that shed light on the epidemiology and pathophysiology of infections in patients with solid tumors. In addition, this review focuses upon the diagnosis and treatment of these infections and their recent advances.

Predictors of nipple ischemia after nipple sparing mastectomy

Nipple sparing mastectomy (NSM) has become an accepted approach in selected cases of breast cancer and prophylactic mastectomy. Various surgical techniques have been described and nipple ischemia has been a common complication. Potential risk factors for nipple ischemia after NSM are examined. To examine predisposing factors for nipple ischemia after NSM. Prospective evaluation of 71 consecutive NSM in 45 patients from 2009 to 2011 was performed. There were 40 mastectomies for cancer (56.3%), and 31 (43.7%) prophylactic mastectomies. In cases of cancer, the ducts were excised from the undersurface of the nipple. Reconstructive methods included: expander 58, latissimus flap/expander 2, implant 10, and free TRAM flap 1. Various patient and technical factors were examined for impact on nipple ischemia. Partial nipple necrosis occurred in 20 cases (28.2%). Nineteen cases healed uneventfully and one required secondary nipple reconstruction. Operations for cancer (OR 10.54, CI 1.88-59.04, p = 0.007) and periareolar incisions (OR 9.69, CI 1.57-59.77, p = 0.014) predisposed to nipple ischemia. Periareolar incisions and dissection of the nipple ducts for cancer have a higher risk of nipple necrosis after NSM.

Breast cancer surgery without suction drainage: the impact of adopting a 'no drains' policy on symptomatic seroma formation rates

AIM

To determine the effect of a 'no drains' policy on seroma formation and other complications in women undergoing breast cancer surgery.

MATERIALS AND METHODS

Before May 2010 drains were routinely used in our unit following mastectomy ± axillary surgery and axillary lymph node dissection (ALND) ± wide local excision (WLE). Since then, a 'no drains' policy has been adopted. Data was collected prospectively between 01/12/06 and 30/11/11 to compare symptomatic seroma, wound infection, re-admission and re-operation rates in women treated with a drain and those without.

RESULTS

596 women were included in the study. 247 women underwent modified radical mastectomy (MRM) and ALND (Group 1), 184 MRM ± sentinel lymph node biopsy (SLNB)/axillary node sampling (ANS) (Group 2) and 165 ALND ± WLE (Group 3). In group 1, 149 had a drain, in group 2, 62, and in group 3, 50. Within each group, the presence or absence of a drain did not significantly affect the rate of symptomatic seroma, number of aspirations performed, wound infection rates or the incidence of complications requiring re-admission. Having a drain was associated with lower volumes of seroma aspirated. In all three groups, the presence of a drain was associated with a longer hospital stay (p < 0.001).

CONCLUSION

This study suggests that MRM ± ALND/SLNB/ANS and ALND ± WLE can be performed without the use of suction drains without increasing seroma formation and other complication rates. Adopting a 'no-drains' policy may also contribute to earlier hospital discharge.

Obesity increases operating room time for lobectomy in the society of thoracic surgeons database

BACKGROUND

Obesity has become a major epidemic in the United States. Although research suggests obesity does not increase major morbidity or mortality after thoracic operations, it likely results in greater use of health care resources.

METHODS

We examined all patients in The Society of Thoracic Surgeons General Thoracic Surgery database with primary lung cancer who underwent lobectomy from 2006 to 2010. We investigated the impact of body mass index (BMI) on total operating room time using a linear mixed-effects regression model and multiple imputations to account for missing data. Secondary outcomes included postoperative length of stay and 30-day mortality. Covariates included age, sex, race, forced expiratory volume, smoking status, Zubrod score, prior chemotherapy or radiation, steroid use, number of comorbidities, surgical approach, hospital lobectomy volume, hospital percent obesity, and the addition of mediastinoscopy or wedge resection.

RESULTS

A total of 19,337 patients were included. The mean BMI was 27.3 kg/m2, with 4,898 patients (25.3%) having a BMI of 30 kg/m2 or greater. The mean total operating room time, length of stay, and 30-day mortality were 240 minutes, 6.7 days, and 1.8%, respectively. For every 10-unit increase in BMI, mean operating room time increased by 7.2 minutes (range, 4.8 to 8.4 minutes; p<0.0001). Higher hospital lobectomy volume and hospital percentage of obese patients did not affect the association between BMI and operative time. Body mass index was not associated with 30-day mortality or increased length of stay.

CONCLUSIONS

Increased BMI is associated with increased total operating room time, regardless of institutional experience with obese patients.

Axillary lymphadenectomy for breast cancer. A randomized controlled trial comparing a bipolar vessel sealing system to the conventional technique

AIM

To compare safety and efficacy of a bipolar vessel sealing system (BVSS) to the conventional technique in axillary node dissection.

METHODS

116 women with breast cancer were randomized to conventional node dissection surgical technique (control; n = 58) by scalpel and monopolar cautery or using an electrothermal BVSS (study group; n = 58).

RESULTS

The median (range) total volume of fluid collected by drain and aspirations was 305 (30-1420) mL in the study group and 335 (80-1070) mL in the control group (p = 0.325). The median (range) total volume of lymph collected by percutaneous aspirations was 207.5 (40-1050) mL in the study group and 505 (270-705) mL in the control group (p = 0.010). The incidence of seroma was similar in both groups (p = 0.845). The axillary drain was removed earlier in the study group than in controls (p = 0.046).

CONCLUSION

The use of a BVSS offers marginal advantages when compared to the conventional technique.

Axillary Padding without Drainage after Axillary Lymphadenectomy - a Prospective Study of 299 Patients with Early Breast Cancer

BACKGROUND: After lymphadenectomy for early breast cancer, seroma formation is a constant event requiring a suction drainage. This drainage is the strongest obstacle to reducing the hospital stay. Axillary padding without drainage appears to be a valuable option amid the various solutions for reducing the hospital stay. METHODS: We conducted a comparison between 114 patients with padding and 185 patients with drainage. Data were obtained from 2 successive prospective studies. RESULTS: The mean hospital stay was 2.4 days (range 1-4) in the padding group and 4.2 days (range 2-9) in the drainage group (p < 0.05). There were fewer needle aspirations for seroma in the padding group (8.8 vs. 23%, p < 0.05). At 6 weeks, only 28% (32/114) of the patients in the padding group reported pain versus 51% (94/185) in the drainage group. The mean pain intensity at 6 weeks was 3 and 4.3 respectively (p < 0.0001). CONCLUSION: Axillary padding without drainage was associated with a better post-operative course than suction drainage in this historical comparison, and the hospital stay was significantly shortened. There are only few series published on this new technique but they all indicate good feasibility and good tolerance. A large randomised multicentric evaluation is now warranted.

High body mass index and smoking predict morbidity in breast cancer surgery: a multivariate analysis of 26,988 patients from the national surgical quality improvement program database

OBJECTIVE

The purpose of this study was to examine the incidence of complications of breast cancer surgery in a multi-institutional, prospective, validated database and to identify preoperative risk factors that predispose to these complications.

BACKGROUND

There is an increased emphasis on clinical outcomes to improve the quality of surgical care. Although mastectomy and breast conserving surgery have low risk for complications, few US studies have examined the incidence of these complications in large, multicenter patient populations. The broad scale of the National Surgical Quality Improvement Program (NSQIP) data set facilitates multivariate analysis of patient characteristics that predispose to development of postoperative complications in breast cancer surgery.

METHODS

A prospective, multi-institutional study of patients undergoing mastectomy and breast conserving surgery was performed from the National Surgical Quality Improvement Program from 2005 to 2007. Study subjects were selected as a random sample of patients at more than 200 participating community and academic medical centers. Thirty-day morbidity was prospectively collected and the incidence of postoperative complications was determined, with particular emphasis on superficial and deep surgical site infections. Multivariate logistic regression was performed to identify independent risk factors for postoperative wound infections in each.

RESULTS

A total of 26,988 patients were identified who underwent mastectomy (N = 10,471) and breast conserving surgery (N = 16,517). As expected, the overall 30-day morbidity rate for all procedures was low (5.6%), with significantly higher morbidity for mastectomies (4.0%) than breast conserving surgery (1.6%, P < 0.001). The most common complications in all procedures were superficial surgical site infections and deep surgical site infections. Independent risk factors for development of any wound infection in patients undergoing mastectomy were a high body mass index, smoking, and diabetes (ORs = 1.8, 1.6, 1.8). In patients who had a lumpectomy, a high body mass index, smoking, and a history of surgery within 90 days prior to this procedure (ORs = 1.7, 1.9, 2.0) were independent risk factors.

CONCLUSIONS

Although complication rates in breast cancer surgery are low, wound infections remain the most common complication. A high body mass index and current tobacco use were the only independent risk factors for development of a postoperative wound infection across all procedures. This study highlights the benefit of a multi-institutional database in assessing risk factors for adverse outcomes in breast cancer surgery.

Axillary lymph node dissection for breast cancer utilizing Harmonic Focus®

Background

For patients with axillary lymph node metastases from breast cancer, performance of a complete axillary lymph node dissection (ALND) is the standard approach. Due to the rich lymphatic network in the axilla, it is necessary to carefully dissect and identify all lymphatic channels. Traditionally, these lymphatics are sealed with titanium clips or individually sutured. Recently, the Harmonic Focus^®, a hand-held ultrasonic dissector, allows lymphatics to be sealed without the utilization of clips or ties. We hypothesize that ALND performed with the Harmonic Focus^® will decrease operative time and reduce post-operative complications.

Methods

Retrospective review identified all patients who underwent ALND at a teaching hospital between January of 2005 and December of 2009. Patient demographics, presenting pathology, treatment course, operative time, days to drain removal, and surgical complications were recorded. Comparisons were made to a selected control group of patients who underwent similar surgical procedures along with an ALND performed utilizing hemostatic clips and electrocautery. A total of 41 patients were included in this study.

Results

Operative time was not improved with the use of ultrasonic dissection, however, there was a decrease in the total number of days that closed suction drainage was required, although this was not statistically significant. Complication rates were similar between the two groups.

Conclusion

In this case-matched retrospective review, there were fewer required days of closed suction drainage when ALND was performed with ultrasonic dissection versus clips and electrocautery.

Perioperative reductions in circulating lymphocyte levels predict wound complications after excisional breast cancer surgery

OBJECTIVE

Postoperative wound complications after excisional surgery for primary breast cancer can result in patients requiring additional treatments and delay adjuvant therapy and are associated with worse prognoses.We investigated factors that might predispose patients to wound complications.

BACKGROUND

A number of patient characteristics have been associated with wound complications, but there is currently no quantitative measure of the risk of their occurrence. Our hypothesis was that wound complications are related, in part, to the immune status of patients.

METHODS

We recruited patients undergoing surgery for primary breast cancer and determined their circulating levels of various immune cells shortly before and after surgery as a measure of immune status.

RESULTS

One hundred seventeen patients were recruited; 16 (13.7%) developed wound complications. The following patient and tumor characteristics were associated with higher wound complication rates: diabetes (P = 0.02); larger tumors (T2/3 vs T1; P = 0.02); metastatic axillary nodes (P = 0.006). With respect to immune status, no significant differences in preoperative levels of circulating immune cells were detected between patients who developed wound complications and those who did not. However, patients who developed complications showed greater reductions in lymphocyte levels 4 hours postoperatively than those who did not (P <0.001). Multivariate analyses demonstrated that falls in lymphocyte levels of greater than 20% or 50% 4 hours postoperatively acted as a significant and independent predictor of wound complications (P < 0.005 and P < 0.0001,respectively).

CONCLUSIONS

Perioperative changes in lymphocyte levels could provide a practical predictive marker for wound complications on which selective antibiotic prophylaxis could be based.

Local, regional, and systemic recurrence rates in patients undergoing skin-sparing mastectomy compared with conventional mastectomy

BACKGROUND

Although the use of SSM is becoming more common, there are few data on long-term, local-regional, and distant recurrence rates after treatment. The purpose of this study was to examine the rates of local, regional, and systemic recurrence, and survival in breast cancer patients who underwent skin-sparing mastectomy (SSM) or conventional mastectomy (CM) at our institution.

METHODS

Patients with stage 0 to III unilateral breast cancer who underwent total mastectomy at our center from 2000 to 2005 were included in this study. Kaplan-Meier curves were calculated, and the log-rank test was used to evaluate the differences between overall and disease-free survival rates in the 2 groups.

RESULTS

Of 1810 patients, 799 (44.1%) underwent SSM and 1011 (55.9%) underwent CM. Patients who underwent CM were older (58.3 vs 49.3 years, P<.0001) and were more likely to have stage IIB or III disease (53.0% vs 31.8%, P<.0001). Significantly more patients in the CM group received neoadjuvant chemotherapy and adjuvant radiation therapy (P<.0001). At a median follow-up of 53 months, 119 patients (6.6%) had local, regional, or systemic recurrences. The local, regional, and systemic recurrence rates did not differ significantly between the SSM and CM groups. After adjusting for clinical TNM stage and age, disease-free survival rates between the SSM and CM groups did not differ significantly.

CONCLUSIONS

SSM is an acceptable treatment option for patients who are candidates for immediate breast reconstruction. Local-regional recurrence rates are similar to those of patients undergoing CM. Cancer 2011. © 2010 American Cancer Society.

Pharmacokinetics and disposition of a localized lymphatic polymeric hyaluronan conjugate of cisplatin in rodents

Cisplatin (CDDP) is an effective anticancer agent for many solid tumors but has significant systemic toxicity limiting its use in many patients. We have designed a loco-regional delivery system to increase platinum levels in the lymphatics, where early metastasis is most likely to occur, while reducing systemic toxicities. CDDP was conjugated to a biocompatible polymer hyaluronan (HA), with a conjugation degree of approximately 20% (w/w). Conjugates were delivered via subcutaneous injection into the mammary fat pad of rats. Intravenous hyaluronan-cisplatin (HA-Pt) exhibited an increased plasma area under the curve (AUC) 2.7-fold compared to conventional CDDP but with a reduced peak plasma level (C(max)), and HA-Pt increased the ipsilateral lymph node AUC by 3.8-fold compared to CDDP. Urine creatinine was unchanged over 30 days following dosing of HA-Pt. This study demonstrates that intralymphatic drug delivery with polymer-conjugated platinum may provide greater tissue and systemic plasma concentrations of platinum than intravenous CDDP. In addition, localized particle delivery augmented distribution in the loco-regional tissue basin where tumor burden predominates, while renal toxicity compared to standard intravenous CDDP was significantly reduced.

The obesity paradox: body mass index and outcomes in patients undergoing nonbariatric general surgery

OBJECTIVE

We sought to examine the effect of body mass index (BMI) on 30-day morbidity and mortality in a large cohort of patients undergoing nonbariatric general surgery.

SUMMARY BACKGROUND DATA

Obesity has long been considered a risk factor for poor outcomes from a variety of surgical procedures, yet recent studies of critically and chronically ill patients suggest that overweight and obese patients may paradoxically have better outcomes than "normal" weight patients.

METHODS

A prospective, multi-institutional, risk-adjusted cohort study of 118,707 patients undergoing nonbariatric general surgery who were included in the National Surgical Quality Improvement Program Participant Use database in 2005 and 2006 was performed. Outcomes and risk variables were compared across NIH-defined BMI class using analysis of variance, Bonferroni multiple comparisons of means tests, and multivariable logistic regression.

RESULTS

After adjusting for all significant perioperative risk factors, the risk of death according to BMI exhibited a reverse J-shaped relationship, with the highest rates in the underweight and morbidly obese extremes and the lowest rates in the overweight and moderately obese. Overweight (odds ratio, 0.85; 95% CI, 0.75-0.99) and moderately obese (odds ratio, 0.73; 95% CI, 0.57-0.94) patients had a significantly lower risk of death than normal weight patients. There was a progressive increase in the likelihood of a complication with increasing BMI class, almost entirely due to increasing rates of wound infection.

CONCLUSIONS

Overweight and moderately obese patients undergoing nonbariatric general surgery have paradoxically "lower" crude and adjusted risks of mortality compared with patients at a "normal" weight. This finding is in contrast to observations from the general population, confirming the existence of an "obesity paradox" in this patient population.

Effect of being overweight on postoperative morbidity and long-term surgical outcomes in proximal gastric carcinoma

BACKGROUND AND AIM

The prevalence of being overweight has risen remarkably in Korea. This study sought to clarify the relationship between being overweight and surgical outcomes in gastric cancer patients.

METHODS

A total of 410 patients who underwent curative total gastrectomies with D2 dissection from January 2000 to December 2003 were retrospectively studied from a prospectively designed database. The patients were assigned to two groups based upon their body mass index (BMI): non-overweight, BMI < 25 kg/m(2); overweight, BMI >or= 25 kg/m(2). Perioperative surgical outcomes, postoperative morbidity, mortality, recurrence, and prognosis were analyzed.

RESULTS

The overweight group had longer operation time and more postoperative complications than the non-overweight group. The two groups were similar in terms of transfusion volumes, postoperative bowel movement, time to initiation of a soft diet, and postoperative hospital stay. Patterns of recurrence and cumulative survival rates were similar for each group. Multivariate analysis showed that being overweight was not a risk factor for recurrence or poor prognosis.

CONCLUSION

Although being overweight was associated with increased operation time and higher risk of complications in gastric cancer patients undergoing curative total gastrectomy, it had no effect on recurrence or long-term survival.

Intraoperative application of fibrin sealant does not reduce the duration of closed suction drainage following radical axillary lymph node dissection in melanoma patients: a prospective randomized trial in 58 patients

BACKGROUND

Patients suffering from malignant melanoma often require radical lymph node dissection of the axillary nodal basin. The effects of intraoperative application of fibrin sealant following radical axillary lymph node dissection (RALND) on the incidence of postoperative lymphatic secretion are discussed. To study the effect of intraoperatively applied fibrin sealant following RALND a randomized patient-blinded trial was carried out.

METHODS

Fifty-eight patients with axillary lymph node metastases of malignant melanoma underwent therapeutic RALND and were randomized into two groups: 29 patients received 2 cc of fibrin glue intraoperatively and 29 patients were only irrigated with 0.9% saline. The amount of drainage was recorded every 24 h. The main outcome criterion was the duration of drain placement in the wound. Minor criteria were the total amount of fluid and the length of hospital stay. Statistical analysis was performed using Spearman's log-rank correlation and paired t-test.

RESULTS

There was no significant difference between the nonfibrin group 5 days (range = 3.6-5.7 days) and the fibrin group 5 days (range = 4.1-8.5 days) (p = 0.701). The total amount of fluid for the nonfibrin group (410 cc, range = 362-727 cc) and that for the fibrin group (503 cc, range = 369-1098 cc) (p = 0.605) and the length of postoperative hospital stay of 6 days (range = 5.4-7) vs. 7 days (range = 5.9-10.7), respectively, were not different between both groups (p = 0.387).

CONCLUSION

Considering our study results, we cannot recommend the use of 2 cc of fibrin glue intraoperatively in the prevention of lymphatic secretion in patients undergoing RALND for metastatic melanoma.

Risk factors for surgical site infection after major breast operation

BACKGROUND

Understanding surgical site infection (SSI) risk factors after breast operation is essential to develop infection-prevention strategies and improve surgical outcomes.

METHODS

We performed a retrospective case-control study with subjects selected from a cohort of mastectomy, breast reconstruction, and reduction surgical patients between January 1998 and June 2002 at a university-affiliated hospital. SSI cases within 1 year after operation were identified using ICD-9-CM diagnosis codes for wound infection and complication or positive wound cultures, or both. Medical records of 57 patients with breast SSI and 268 randomly selected uninfected control patients were reviewed. Multivariate logistic regression was used to identify independent risk factors for SSI.

RESULTS

Significant independent risk factors for breast incisional SSI included insertion of a breast implant or tissue expander (odds ratio [OR] = 5.3; 95% CI, 2.5 to 11.1), suboptimal prophylactic antibiotic dosing (OR = 5.1; 95% CI, 2.5 to 10.2), transfusion (OR = 3.4; 95% CI, 1.3 to 9.0), mastectomy (OR = 3.3; 95% CI, 1.4 to 7.7), previous chest irradiation (OR = 2.8; 95% CI, 1.2 to 6.5), and current or recent smoking (OR = 2.1; 95% CI, 0.9 to 4.9). Local infiltration of an anesthetic agent was associated with substantially reduced odds of SSI (OR = 0.4; 95% CI, 0.1 to 0.9).

CONCLUSIONS

Suboptimal prophylactic antibiotic dosing is a potentially modifiable risk factor for SSI after breast operation. SSI risk was increased in patients undergoing mastectomy and in patients who had an implant or tissue expander placed during operation. This information can be used to develop a specific risk stratification index to predict SSI and infection-preventive strategies tailored for breast surgery patients.

Impact of body mass index on perioperative outcomes in patients undergoing major intra-abdominal cancer surgery

BACKGROUND

Obesity is an increasingly common serious chronic health condition. We sought to determine the impact of body mass index (BMI) on perioperative outcomes in patients undergoing major intra-abdominal cancer surgery.

METHODS

A prospective, multi-institutional, risk-adjusted cohort study of patients undergoing major intra-abdominal cancer surgery was performed from the 14 university hospitals participating in the Patient Safety in Surgery Study of the National Surgical Quality Improvement Program (NSQIP). Demographic, clinical, and intraoperative variables and 30-day morbidity and mortality were prospectively collected in standardized fashion. Analysis of variance, Bonferroni multiple comparisons of means tests, and multivariable logistic regression analysis were performed.

RESULTS

We identified 2258 patients who underwent esophagectomy (n = 29), gastrectomy (n = 223), hepatectomy (n = 554), pancreatectomy (n = 699), or low anterior resection/proctectomy (n = 753). Patients were stratified by National Institutes of Health (NIH)-defined BMI obesity class, with 573 (25.4%) patients classified as obese (BMI > 30 kg/m(2)). There were no differences in mean work relative value units, total time of operation, or length of stay amongst the BMI classes. After adjusting for other risk factors, obesity was not a risk factor for death or major complications but was a risk factor for wound complications. The risk of postoperative death was greatest in underweight patients (odds ratio [OR] 5.24; 95% confidence interval [CI] 1.7-16.2).

CONCLUSION

In patients undergoing major intra-abdominal cancer surgery, obesity is not a risk factor for postoperative mortality or major complications. Importantly, underweight patients have a fivefold increased risk of postoperative mortality, perhaps a consequence of their underlying nutritional status.

Receipt of appropriate primary breast cancer therapy and adjuvant therapy are not associated with obesity in older women with access to health care

PURPOSE

Many studies have reported body mass index (BMI) increases the risk of breast cancer recurrence and breast cancer-specific mortality. Few studies have reported or examined whether breast cancer treatment differs by BMI. The purpose of this study was to examine the association between BMI at breast cancer diagnosis and receipt of appropriate primary tumor therapy and adjuvant therapy.

METHODS

We identified 897 women age >or= 65 years diagnosed with stage I or II breast cancer from 1990 to 1999 at five health care organizations. We used medical records to confirm demographics, tumor characteristics, treatment, comorbid conditions, and to calculate BMI at diagnosis (< 25 kg/m(2), n = 328; 25 to < 30 kg/m(2), n = 305; 30 to < 35 kg/m(2), n = 188; >or= 35 kg/m(2), n = 76). We defined primary therapy based on National Guidelines as receiving breast-conserving surgery with radiation therapy and axillary node dissection, simple mastectomy with axillary node dissection, or modified radical mastectomy (73% overall); adjuvant therapy was defined as receipt of hormonal therapy, chemotherapy, or both (60% overall).

RESULTS

The median BMI was 26.7 kg/m(2) (range, 14.6 to 61.2). The proportion of women receiving primary therapy and adjuvant therapy was lowest for women less than 25 kg/m(2) (69% and 56%, respectively) and greatest for obese I (78% and 64%, respectively). There were no differences in receipt of primary or adjuvant treatment across BMI in univariate or multivariable models (after adjusting for age, stage, comorbidity, diagnosis year, and hormone receptor positivity).

CONCLUSION

Receipt of appropriate primary therapy and adjuvant therapy is not associated with BMI in older women with access to health care. Additional research in larger samples and more diverse settings is needed.

Morbidity and mortality following breast cancer surgery in women: national benchmarks for standards of care

BACKGROUND

Most reports on postoperative (OP) morbidity and mortality following breast cancer surgery (BCS) are limited by relatively small sample size resulting in a lack of national benchmarks for quality of care. This paper reports the 30-day morbidity and mortality following BCS in women using a large prospective multi-institutional database.

METHODS

The National Surgical Quality Improvement Program Patient Safety in Surgery, prospectively collected inpatient and outpatient 30 day postoperative morbidity and mortality data on patients undergoing surgery at 14 university and 4 community centers. Using the procedure CPT code, the database was queried for all women undergoing mastectomy (MT) or lumpectomy with an axillary procedure (L-ANP). Morbidity and mortality were categorized as mortality, wound, cardiac, renal, pulmonary, and central nervous system. Logistic regression models for the prediction of wound complications were developed. Preoperative variables having bivariate relationships with postoperative wound complications with P < or = 0.20 were submitted for consideration.

RESULTS

We identified 1660 and 1447 women who underwent MT and l-ANP, respectively. The mean age was 55.9 years. The majority of procedures were under general anesthesia. The 30-day postoperative mortality for MT and l-ALNP were 0.24% and 0%, respectively. The most frequent morbid complication was wound infection, more commonly occurring in the mastectomy (4.34%) group versus the lumpectomy group (1.97%). Cardiac and pulmonary complications occurred infrequently in the mastectomy group (cardiac: MT, 0.12%; and pulmonary: MT, 0.66%). There were no cardiac or pulmonary complications in the lumpectomy group. CNS morbidities were rare in both surgical groups (MT, 0.12%; and l-ALNP, 0.07%). Development of a UTI was more common in women who underwent a mastectomy (0.66%) when compared with women that had a lumpectomy (0.14%). The only significant predictors of a wound complication were morbid obesity (BMI >30), having had a MT, low preoperative albumin and hematocrit greater than 45%.

CONCLUSION

Morbidity and mortality rates following BCS in women are low, limiting their value in assessing quality of care. Mastectomy carries higher complication rate than l-ANP with wound infection being the most common.

INFLUENCE OF SURGICAL TECHNIQUE ON AXILLARY SEROMA FORMATION: A RANDOMIZED STUDY

The aim of this study was to evaluate the influence of surgical technique in the form of electrocautery and suction drains on seroma formation following surgery for breast cancer. A prospective randomized study was carried out. One hundred and sixty patients with breast cancer who underwent surgery were allocated to four arms using a 2 x 2 factorial design. This method enabled us to evaluate the independent effect of two different causative factors on the incidence of postoperative seroma formation using a single dataset with limited numbers. The main outcome measure was postoperative seroma formation defined as a postoperative axillary collection requiring more than one aspiration after removal of the drain. The incidence of seroma in our institution is 90%. Incidence of postoperative seroma was 88.3% if electrocautery was used, which reduced to 82.2% if surgery was carried out using scissors for dissection and ligatures for haemostasis (P = 0.358). There was no influence on the incidence of seroma formation whether suction drain (84.6%) or corrugated drains (86.1%) were used (P = 0.822). The use of electrocautery in axillary dissection does not adversely affect postoperative seroma formation after surgery for breast cancer. The use of different drainage techniques has no bearing on the postoperative seroma formation. The surgical technique has no influence on the rate of seroma formation after surgery for breast cancer.

Complications in Breast Surgery

Most breast operations are categorized as low-morbidity procedures, but a variety of complications can occur in association with diagnostic and multidisciplinary management procedures. Some of these complications are related to the breast itself, and others are associated with axillary staging procedures. This article first addresses some general, nonspecific complications (wound infections, seroma formation, hematoma). It then discusses complications that are specific to particular breast-related procedures: lumpectomy (including both diagnostic open biopsy and breast-conservation therapy for cancer), mastectomy; axillary lymph node dissection, lymphatic mapping/sentinel lymph node biopsy, and reconstruction.

[Cost effectiveness of Ligasure Precise versus surgical clips during axillary nodal dissection for breast cancer]

Introduction. The techniques used for axillary node dissection are constantly evolving. The advent of the grip Ligasure Precise raise the question of its cost-effectiveness compared with surgical clips.

OBJECTIVE

To compare the effectiveness of Ligasure compared with surgical clips for simple axillary node dissection or Patey procedure in terms of duration of drainage, cost of hospitalization and complications.

MATERIAL

and method. Retrospective study extending from January 1, 2003 to December 31, 2004, concerning 187 patients who underwent simple axillary dissection (100) or Patey procedure (87), with use of surgical clips or Ligasure followed by drainage.

RESULTS

The use of Ligasure increased the operative cost because its price is higher than that of a clip grip with a refill. Ligasure significantly decreased the duration of drainage in the two groups but there was significantly more abundant fluid loss in the dissection group. The cost of hospitalization related to the choice of the technique of hemostasis (cost of the material + lasted of drainage X price of the day of hospitalization), was not significantly favor of Ligasure. Taking into account the choice of the hemostasis technique and the total duration of hospitalization (material cost + duration of hospitalization X price of the day of hospitalization), there is no significant difference between the two groups.

CONCLUSION

This study compares grip Ligasure Precise with surgical clips for axillary dissection. The duration of drainage was significantly shorter with Ligasure Precise but its benefit in terms of fluid loss remains to be shown. The use of Ligasure does not significantly reduce the cost of hospitalization.

A Single Surgeon???s 12-Year Experience with Tissue Expander/Implant Breast Reconstruction: Part I. A Prospective Analysis of Early Complications

BACKGROUND

Multiple prior reports are conflicted regarding the true incidence of complications following implant-based breast reconstruction. A review of a single surgeon's extensive experience with tissue expander/implant reconstruction provides the opportunity to critically evaluate outcomes in a uniformly treated patient population. The objective of this study was to analyze the development of early complications in patients following two-stage implant breast reconstruction.

METHODS

A review of all tissue expander/implant reconstructions performed by a single surgeon over the 12-year period from July of 1992 to June of 2004 was performed. A prospectively maintained database was analyzed with respect to reconstructive and early complication data on 1522 reconstructions in 1221 patients. Early complications were defined as those occurring 12 months or less from initiation of reconstruction.

RESULTS

The overall rate of early complications was 5.8 percent; the rate of premature expander removal was 2.7 percent. The most common complication was infection (2.5 percent). The incidence of complications after tissue expander insertion (8.5 percent) was significantly higher than that after the exchange procedure (2.7 percent). The rate of complications was significantly higher in patients with a history of preoperative chest wall irradiation. There was no difference in the incidence of complications in patients who were expanded during chemotherapy and those who were not.

CONCLUSIONS

Tissue expander/implant reconstruction is a safe, reliable method of reconstruction with minimal early complications. Early complications are more common after expander insertion. Chemotherapy administered during tissue expansion does not increase the rate of complications. The rate of complications, although higher in previously irradiated patients, remains low.

Obesity as a risk factor for development and poor prognosis of breast cancer

The evidence that obesity adversely affects women's health is overwhelming and indisputable. The risk of postmenopausal breast cancer increases with obesity; measured as weight gain, body mass index, waist-hip ratio or percent body fat. It is also established that obesity is associated with poor prognosis of breast cancer. This review examines in detail the possible mechanisms by which obesity causes poor prognosis of breast cancer such as estrogenic activity, advanced or more aggressive disease at diagnosis and high likelihood of both local and systemic treatment failure. After careful consideration of the available evidence, the author concludes that obesity contributes towards development and poor prognosis of breast cancer; therefore, weight management should be an integral part of any strategy to prevent and improve the outcome of breast cancer.
