Abstract
Inflammation contributes to the immunosuppressive microenvironment and leads to the recurrence of surgically resected tumors. The COX-2/PGE2 axis is considered a key player in shaping the immunosuppression microenvironment. However, targeted modulation of the postoperative tumor microenvironment is challenging. To specifically curb the inflammation and alleviate immunosuppression, here, we developed a PGE2 inhibitor celecoxib (CXB)-loaded bionic nanoparticle (CP@CM) coated with activated murine vascular endothelial cell (C166 cells) membrane to target postoperative melanoma and inhibit its recurrence. CP@CM adhered to inflammatory white blood cells (WBCs) through the adhesion molecules, including ICAM-1, VCAM-1, E-selectin, and P-selection, expressed on the surface of C166 cells. Leveraging the natural tropism of the WBC to the inflammatory postoperative tumor site, CP@CM efficiently targeted postoperative tumors. In melanoma postoperative recurrence models, CXB significantly reduced PGE2 secretion and the recruitment of immunosuppressive cells such as myeloid-derived suppressor cells (MDSCs) and regulatory T cells (Treg) by inhibiting the activity of COX-2. This was followed by an increase in the infiltration of CD8+ T cells and CD4+ T cells in tumor tissues. Additionally, the immune responses were further enhanced by combining a PD-L1 monoclonal antibody. Ultimately, this immunotherapeutic strategy reversed the tumor immunosuppressive microenvironment and inhibited tumor recurrence, demonstrating a promising potential for postoperative immunotherapy for melanoma.

[PMID: 38457241 PMCID: PMC10923041 DOI: 10.1002/cam4.6917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Revised: 12/18/2023] [Accepted: 12/25/2023] [Indexed: 03/10/2024] Open
Abstract
BACKGROUND In this study, we investigated infection-related tumor growth, focusing on myeloid-derived suppressor cells (MDSCs) in clinical and experimental settings. PATIENTS AND METHODS In the clinical study, a total 109 patients who underwent gastrectomy or esophagectomy were included. Blood samples were collected from a preoperative time point through 3 months after surgery, and MDSCs were analyzed using flow cytometry. In animal experiments, peritonitis model mice were created by CLP method. We investigated the number of splenic MDSCs in these mice using flow cytometry. Malignant melanoma cells (B16F10) were inoculated on the back of the mice, and tumor growth was monitored. We compared the level of MDSC infiltration around the tumor and the migration ability between CLP and sham-operated mice-derived MDSCs. Finally, we focused on PD-L1+ MDSCs to examine the effectiveness of anti-PD-L1 antibodies on tumor growth in CLP mice. RESULTS In patients with postoperative infectious complication, MDSC number was found to remain elevated 3 months after surgery, when the inflammatory responses were normalized. CLP mice showed increased numbers of MDSCs, and following inoculation with B16F10 cells, this higher number of MDSCs was associated with significant tumor growth. CLP-mice-derived MDSCs had higher levels of accumulation around the tumor and had more enhanced migration ability. Finally, CLP mice had increased numbers of PD-L1+ MDSCs and showed more effective inhibition of tumor growth by anti-PD-L1 antibodies compared to sham-operated mice. CONCLUSION Long-lasting enhanced MDSCs associated with infection may contribute to infection-related tumor progression.

Abstract
BACKGROUND The prognostic impact of major postoperative complications (POCs) for intrahepatic cholangiocarcinoma (ICC) remains ill-defined. We sought to analyze the relationship between POCs and outcomes relative to lymph node metastases (LNM) and tumor burden score (TBS). METHODS Patients who underwent resection of ICC between 1990-2020 were included from an international database. POCs were defined according to Clavien-Dindo classification ≥ 3. The prognostic impact of POCs was estimated relative to TBS categories (i.e., high and low) and lymph node status (i.e., N0 or N1). RESULTS Among 553 patients who underwent curative-intent resection for ICC, 128 (23.1%) individuals experienced POCs. Low TBS/N0 patients who experienced POCs presented with a higher risk of recurrence and death (3-year cumulative recurrence rate; POCs: 74.8% vs. no POCs: 43.5%, p = 0.006; 5-year overall survival [OS], POCs 37.8% vs. no POCs 65.8%, p = 0.003), while POCs were not associated with worse outcomes among high TBS and/or N1 patients. The Cox regression analysis confirmed that POCs were significant predictors of poor outcomes in low TBS/N0 patients (OS, hazard ratio [HR] 2.91, 95%CI 1.45-5.82, p = 0.003; recurrence free survival [RFS], HR 2.42, 95%CI 1.28-4.56, p = 0.007). Among low TBS/N0 patients, POCs were associated with early recurrence (within 2 years) (Odds ratio [OR] 2.79 95%CI 1.13-6.93, p = 0.03) and extrahepatic recurrence (OR 3.13, 95%CI 1.14-8.54, p = 0.03), in contrast to patients with high TBS and/or nodal disease. CONCLUSIONS POCs were independent, negative prognostic determinants for both OS and RFS among low TBS/N0 patients. Perioperative strategies that minimize the risk of POCs are critical to improving prognosis, especially among patients harboring favorable clinicopathologic features.

Abstract
Objective To explore the influences of total intravenous anesthesia (TIVA) and inhaled-intravenous anesthesia on the prognosis of patients with lung, breast, or esophageal cancer. Methods In this retrospective cohort study, patients with lung, breast, or esophageal cancer who underwent surgical treatments at Beijing Shijitan Hospital between January 2010 and December 2019 were included. The patients were categorized into the TIVA group and inhaled-intravenous anesthesia group, according to the anesthesia methods used for the patients for surgery of the primary cancer. The primary outcome of this study included overall survival (OS) and recurrence/metastasis. Results Totally, 336 patients were included in this study, 119 in the TIVA group and 217 in the inhaled-intravenous anesthesia group. The OS of patients in the TIVA group was higher than in the inhaled-intravenous anesthesia group (P = 0.042). There were no significant differences in the recurrence/metastasis-free survival between the two groups (P = 0.296). Inhaled-intravenous anesthesia (HR = 1.88, 95%CI: 1.15-3.07, P = 0.012), stage III cancer (HR = 5.88, 95%CI: 2.57-13.43, P < 0.001), and stage IV cancer (HR = 22.60, 95%CI: 8.97-56.95, P < 0.001) were independently associated with recurrence/ metastasis. Comorbidities (HR = 1.75, 95%CI: 1.05-2.92, P = 0.033), the use of ephedrine, noradrenaline or phenylephrine during surgery (HR = 2.12, 95%CI: 1.11-4.06, P = 0.024), stage II cancer (HR = 3.24, 95%CI: 1.08-9.68, P = 0.035), stage III cancer (HR = 7.60, 95%CI: 2.64-21.86, P < 0.001), and stage IV cancer (HR = 26.61, 95%CI: 8.57-82.64, P < 0.001) were independently associated with OS. Conclusion In patients with breast, lung, or esophageal cancer, TIVA is preferable than inhaled-intravenous anesthesia group for longer OS,, but TIVA was not associated with the recurrence/metastasis-free survival of patients.

Abstract
Every year, 19.3 million patients worldwide are diagnosed with cancer. Surgical resection represents a major therapeutical option and the vast majority of these patients receive anesthesia. However, despite surgical resection, almost one third of these patients develop local recurrence or distant metastases. Perioperative factors, such as surgical stress and anesthesia technique, have been suggested to play a role to a greater or lesser extent in the development of recurrences, but oncology encompasses a complicated tumor biology of which much is still unknown. The effect of total intravenous anesthesia (TIVA) or volatile anesthesia (VA) on survival after oncological surgery has become a popular topic in recent years. Multiple studies conclude in favor of propofol. Despite the a priori probability that relevant differences in postoperative outcomes are due to the anesthesia technique employed, TIVA or VA, is extremely small. The existing literature includes mainly hypothesis-forming retrospective studies and small randomized trials with many methodological limitations. To date, it is unlikely that use of TIVA or VA affect cancer-free survival days to a clinically relevant extent. This review addresses all relevant studies in the field and provides a substantiated different view on this deeply controversial research topic.

Abstract
We performed a meta-analysis to evaluate the oncological results in women with wound complications following mastectomy and immediate breast reconstruction. A systematic literature search up to August 2022 was performed and 1618 subjects with mastectomy and immediate breast reconstruction at the baseline of the studies; 443 of them were with wound complications, and 1175 were with no wound complications as a control. Odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) were calculated to assess the oncological results in women with wound complications following mastectomy and immediate breast reconstruction using dichotomous or contentious methods with a random or fixed-effect model. The wound complications had a significantly longer length of time to adjuvant therapy (MD, 9.44; 95% CI, 4.07-14.82, P < .001) compared with no wound complications in subjects with mastectomy and immediate breast reconstruction. However, no significant difference was found between wound complications and no wound complications in subjects with mastectomy and immediate breast reconstruction in breast cancer recurrence (OR, 1.96; 95% CI, 0.95-4.06, P = .07), death rates (OR, 1.95; 95% CI, 0.89-4.27, P = .09), and kind of immediate breast reconstruction (OR, 1.01; 95% CI, 0.53-1.92, P = .98). The wound complications had a significantly longer length of time to adjuvant, however, no significant difference was found in breast cancer recurrence, death rates, and kind of immediate breast reconstruction. The analysis of outcomes should be done with caution even though no low sample size was found in the meta-analysis but a low number of studies was found in certain comparisons.

Abstract
Background Surgical site infection (SSI) is a well-known complication after breast cancer surgery. The primary aim was to assess risk factors for SSI. Risk factors for other wound complications were also studied. Materials and Methods In this prospectively registered cohort study, patients who underwent breast-conserving surgery (BCS) or mastectomy between May 2017 and May 2019 were included. Data included patient and treatment characteristics, infection, and wound complication rates. Risk factors for SSI and wound complications were analyzed with simple and multiple logistic regression. Results The study cohort consisted of 592 patients who underwent 707 procedures. There were 66 (9.3%) SSI and 95 (13.4%) wound complications. "BMI > 25," "oncoplastic BCS," "reoperation within 24 hour," and "prolonged operative time" were risk factors for SSI with simple analysis. BMI 25-30 and >30 remained as significant risk factors for SSI with adjusted analysis. Risk factors for "any wound complication" with adjusted analysis were "mastectomy with/without reconstruction" in addition to "BMI 25-30" and "BMI > 30." Conclusion The only significant risk factor for SSI on multivariable analysis were BMI 25-30 and BMI > 30. Significant risk factors for "any wound complication" on multivariable analysis were "mastectomy with/without reconstruction" as well as "BMI 25-30" and "BMI > 30".

Abstract
BACKGROUND Postoperative complications may activate prometastatic systemic pathways through tissue damage, wound healing, infection, and inflammation. Postoperative complications are associated with inferior survival in several types of cancer. The aim was to determine the association between postoperative complications and survival in breast cancer. METHODS This population-based cohort included women operated for T1-3 N0-3 M0 invasive breast cancer in Sweden from 2008 to 2017. Only major surgical postoperative complications leading to readmission and/or reoperation within 30 days were considered. Main outcomes were overall survival (OS) and breast cancer-specific survival (BCSS). Prospectively collected nationwide register data were used. Multivariable Cox models were adjusted for clinical and socioeconomic confounders and co-morbidity. RESULTS Among 57 152 women, major surgical postoperative complications were registered for 1854 patients. Median follow-up was 6.22 (0.09-11.70) years. Overall, 9163 patients died, and 3472 died from breast cancer. Major surgical postoperative complications were more common after mastectomy with or without immediate reconstruction (7.3 and 4.3 per cent respectively) than after breast-conserving surgery (2.3 per cent). Unadjusted 5-year OS and BCSS rates were 82.6 (95 per cent c.i. 80.8 to 84.5) and 92.1 (90.8 to 93.5) per cent respectively for women with a major surgical postoperative complication, and 88.8 (88.6 to 89.1) and 95.0 (94.8 to 95.2) per cent for those without a complication (P < 0.001). After adjustment, all-cause and breast cancer mortality rates remained higher after a major surgical postoperative complication (OS: HR 1.32, 95 per cent c.i. 1.15 to 1.51; BCSS: HR 1.31, 1.04 to 1.65). After stratification for type of breast surgery, this association remained significant only for women who had mastectomy without reconstruction (OS: HR 1.41, 1.20 to 1.66; BCSS: HR 1.36, 1.03 to 1.79). CONCLUSION Major surgical postoperative complications are associated with inferior survival, especially after mastectomy. These results underline the importance of surgical de-escalation.

Abstract
Aim Demand for nipple- and skin- sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. Methods A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. Results The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recommendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. Conclusions The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BR Autologous breast reconstruction is increasingly preferred over implants in the setting of radiation therapy. Use of patient-reported outcomes is endorsed. Shape and size of reconstructed breasts can hinder radiotherapy planning. There is a need for randomised phase III trials.

A neutrophil-mediated carrier regulates tumor stemness by inhibiting autophagy to prevent postoperative triple-negative breast cancer recurrence and metastasis. Acta Biomater 2022; 145:185-199. [PMID: 35447368 DOI: 10.1016/j.actbio.2022.04.017] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 03/14/2022] [Accepted: 04/09/2022] [Indexed: 02/05/2023]
Abstract
Recurrence and metastasis after resection are still the main challenges in clinical treatment of breast cancer. Residual tumor and cancer stem-like cells are the primary culprits of recurrence and metastasis. Recent research studies indicate that autophagy is a cytoprotective mechanism of tumors, which maintains the stemness of cancer cells and promotes tumor proliferation and metastasis. Here, we constructed a "Trojan horse" using neutrophils as the carrier (PH-RL@NEs) to prevent the recurrence and metastasis of postoperative breast cancer. Neutrophils, as a "Trojan horse," can quickly respond to postoperative inflammation and accurately deliver drugs to the residual tumor site. The inflammation-triggered "Trojan horse" was then opened to release the liposomes containing the chemotherapeutic drug paclitaxel (PTX) and the autophagy inhibitor hydroxychloroquine (HCQ). We found that HCQ could effectively inhibit tumor cell autophagy, interfere with tumor epithelial-mesenchymal transition, and reduce the tumor stem cell-like population. In the orthotopic 4T1 postoperative recurrence models, PTX and HCQ synergistically killed tumors and regulated the stemness of tumor cells, thereby significantly inhibiting tumor recurrence and metastasis. Our work proved that the inhibition of autophagy to reduce tumor stemness is feasible and effective, which opens up a new prospect for postoperative tumor treatment. STATEMENT OF SIGNIFICANCE: The present study aimed to solve the issues of postoperative recurrence and metastasis of breast cancer and low efficiency of drug administration after surgery. For this purpose, we constructed neutrophils containing hydroxychloroquine (HCQ) and paclitaxel (PTX) co-loaded liposomes (PH-RL@NEs), which for the first time regulated the stemness of tumor cells by inhibiting autophagy, thereby inhibiting postoperative recurrence and metastasis of breast cancer cells. The results showed that PH-RL@NEs enhanced the targeted drug delivery efficiency, with the help of postoperative inflammation chemotaxis of neutrophils. HCQ effectively inhibited autophagy of tumor cells and reduced tumor stem cell-like cells, thus improving the therapeutic effect in the 4T1 in situ postoperative recurrence model.

Abstract
The development of multifunctional biomaterials as both tissue regeneration and drug delivery devices is currently a major focus in biomedical research. Tannic Acid (TA), a naturally occurring plant polyphenol, displays unique medicinal abilities as an antioxidant, an antibiotic, and as an anticancer agent. TA has applications in biomaterials acting as a crosslinker in polymer hydrogels improving thermal stability and mechanical properties. We have developed injectable cell seeded collagen beads crosslinked with TA for breast reconstruction and anticancer activity following lumpectomy. This study determined the longevity of the bead implants by establishing a degradation time line and TA release profile in vivo. Beads crosslinked with 0.1% TA and 1% TA were compared to observe the differences in TA concentration on degradation and release. We found collagen/TA beads degrade at similar rates in vivo, yet are resistant to complete degradation after 16 weeks. TA is released over time in vivo through diffusion and cellular activity. Changes in mechanical properties in collagen/TA beads before implantation to after 8 weeks in vivo also indicate loss of TA over a longer period of time. Elastic moduli decreased uniformly in both 0.1% and 1% TA beads. This study establishes that collagen/TA materials can act as a drug delivery system, rapidly releasing TA within the first week following implantation. However, the beads retain TA long term allowing them to resist degradation and remain in situ acting as a cell scaffold and tissue filler. This confirms its potential use as an anticancer and minimally invasive breast reconstructive device following lumpectomy.

Abstract
OBJECTIVE Immediate direct-to-implant breast reconstruction with acellular dermal matrix (ADM) is the method of choice for many plastic surgeons and patients, but the use of ADM remains a controversial subject in the literature. This study aimed to investigate complications, reconstructive failure and possible risk factors in direct-to-implant breast reconstruction with ADM (primarily Strattice™). METHODS We retrospectively examined all patients undergoing immediate direct-to-implant breast reconstruction with ADM, during a five-year period (2014-2019) at a university clinic. Study outcomes were all complications and explantations. Complications were stratified within and after 6 months postoperatively and subcategorized by type of intervention. Explantations were subcategorized into loss of implant or salvage with immediate insertion of a tissue expander, the same or a new implant. RESULTS We included 154 patients and 232 breasts. Complications within 6 months per patient included hematoma (4%), seroma (8%), infection (9%), necrosis, wound dehiscence and delayed wound healing (19%). The total complication rate per patient was 34%. Explantation occurred in 20 patients (13%) of which 9 (6% of all) had implant loss. Preoperative radiotherapy was a significant predictor of explantation (adjusted OR 4.9, 95% confidence interval (CI), 1.0-23.5; p = 0.045), and smoking was also associated with risk of explantation, although only borderline significant (adjusted OR 4.0, 95% CI, 1.0-15.8; p = 0.050). CONCLUSION This study demonstrates acceptable rates of re-operations and implant loss compared to other studies but highlights the importance of proper patient selection with regards to risk factors to minimize complications.

Abstract
Background Surgical-site infection (SSI) is a well known complication after breast cancer surgery and has been reported to be associated with cancer recurrence. The aim of this study was to investigate the association between SSI and breast cancer recurrence, adjusting for several known confounders. The secondary aim was to assess a possible association between any postoperative infection and breast cancer recurrence. Method This retrospective cohort study included all patients who underwent breast cancer surgery from January 2009 to December 2010 in the Uppsala region of Sweden. Data collected included patient, treatment and tumour characteristics, infection rates and outcome. Association between postoperative infection and oncological outcome was examined using Kaplan–Meier curves and Cox regression analysis. Results Some 492 patients (439 with invasive breast cancer) with a median follow-up of 8.4 years were included. Mean(s.d.) age was 62(13) years. Sixty-two (14.1 per cent) of those with invasive breast cancer had an SSI and 43 (9.8 per cent) had another postoperative infection. Some 26 patients had local recurrence; 55 had systemic recurrence. Systemic recurrence was significantly increased after SSI with simple analysis (log rank test, P = 0.035) but this was not observed on adjusted analysis. However, tumour size and lymph node status remained significant predictors for breast cancer recurrence on multiple regression. Other postoperative infections were not associated with recurrence. Conclusion Neither SSI nor other postoperative infections were associated with worse oncological outcome in this study. Rather, other factors that relate to both SSI and recurrence may be responsible for the association seen in previous studies.

Abstract
INTRODUCTION Frailty can be quantified using an index score to effectively predict surgical outcomes and complications. The modified frailty index (mFI) score includes 5 patient-specific medical history comorbidities including diabetes mellitus, congestive heart failure, hypertension, chronic obstructive pulmonary disease/pneumonia, and nonindependent functional status. The purpose of our study was to apply the 5-item mFI score to predict and minimize complications in patients undergoing breast reconstruction. METHODS The National Surgical Quality Improvement Program was queried for all patients undergoing primary breast reconstruction from 2016 to 2018. Patients were divided based on timing of reconstruction and type of reconstruction: immediate or delayed, and implant based or autologous based. A validated modified fragility score was applied to all patients. Patients were stratified by mFI scores of 0 (no comorbidities), 1 (1 comorbidity), and 2+ (2 or more comorbidities). Patient demographics and 30-day complications rates were recorded. RESULTS A total of 22,700 patients were identified. There were 10,673 patients who underwent immediate breast reconstruction, and 12,027 patients who underwent delayed breast reconstruction. A total of 14,159 patients underwent implant-based, and 8541 underwent autologous-based reconstruction. A total of 16,627 patients had an mFI score of 0, 4923 had a mFI score of 1, and 1150 had a mFI score of 2+. Compared with patients with an mFI score of 0, patients with an mFI score of 2 or greater were more likely to develop a postoperative complication (7.2 vs 12.3; P < 0.0001). Patients undergoing immediate reconstruction were more likely to develop a postoperative complications for every mFI category. The most common complications were wound and hematologic related. CONCLUSION Patients with higher mFI scores are likely to have an increase in postoperative complications after breast reconstruction. Increasing body mass index increases postoperative complications independent of frailty index scores. Patients with increasing frailty index scores undergoing immediate breast reconstruction have a significantly higher risk of postoperative complications compared with delayed reconstruction.Patients with increasing frailty index scores undergoing autologous breast reconstruction have a significantly higher risk of postoperative complications compared with implant-based reconstruction. High frailty index scores are associated with a higher risk of postoperative complications, reoperation rates, and readmission rates. Patients with higher mFI scores may benefit from a delayed implant-based reconstruction.

Abstract
BACKGROUND Operative complications affect recurrence in non-breast malignancies. Rising rates of mastectomy with immediate reconstruction and their increased post-operative complications fuel concerns for poorer outcome in breast cancer (BC). We sought to determine the effect of complications on recurrence in BC patients. METHODS A single-institution retrospective review was conducted of incident BC treated with mastectomy and immediate reconstruction. Overall survival and recurrence were compared between patients with complications to those without. RESULTS Of 201 patients (350 mastectomies, 86 nipple-sparing), 62 (30.8%) had a surgical complication. Patients with complications were older, but groups were similar for type of reconstruction, tobacco use, hormone receptor status, HER2, lymphovascular invasion, and pathologic stage (all p > 0.05). Twenty-two complications (10.9%) were infection, 5 (2.5%) dehiscence, 14 flap necrosis (7%), 21 hematomas (10.4%), and 8 nipple necroses (9%). Recurrence occurred in 18 (8.9%) patients: 4 local, 2 regional, and 12 distant. After 8.9 years of median follow-up, patients with complications trended towards higher recurrence (hazard ratio (HR) 2.23, log-rank p = 0.08, Cox regression p = 0.05), particularly with nipple necrosis (HR 3.28, log-rank p = 0.09, regression p = 0.06). Patients with other complications had similar recurrence-free survival to those without (all p > 0.05). Higher stage (HR 13.66, log-rank p = 0.03) and adjuvant radiation (HR 2.78, log-rank p = 0.04) cases were more likely to recur. Patients with complications had similar overall survival to those without (log-rank p > 0.05). CONCLUSION BC patients with surgical complications do not have lower overall survival. This finding may be due to the improved prognosis compared to non-breast malignancies.

Abstract
Breast reconstruction and oncoplastic surgery have become an important part of breast cancer care. The use of autologous breast reconstruction (ABR) has evolved significantly with advances in microsurgery, aiming to reduce donor site complications and improve cosmesis. For years, immediate-ABR was considered a contraindication if postmastectomy irradiation (PMRT) was planned. As a result of de-escalation of axillary surgery the indication of PMRT are increasing along-side with observations that PMRT in the setting of ABR is not contraindicated. Surgical techniques may result in different amount and areas of breast residual glandular tissue and patient selection is important to reduce potential residual disease. Meticulus radiation planning is important to potentially reduce complications without compromising oncologic outcomes. Surgical techniques change constantly in aim to improve aesthetic results but should most importantly maintain priority to the oncological indications. By multidisciplinary team work with a comprehensive understanding of each discipline, we can preserve the accomplishments of breast surgery in the setting of PMRT, without compromising disease control.

Post-mastectomy surveillance of BRCA1/BRCA2 mutation carriers: Outcomes from a specialized clinic for high-risk breast cancer patients. Breast J 2021; 27:441-447.

Abstract
Female BRCA1/BRCA2 mutation carriers may elect bilateral risk-reducing mastectomy. There is a paucity of data on yield of imaging surveillance after risk-reducing mastectomy. This retrospective study focused on female BRCA1/BRCA2 mutation carriers who underwent bilateral mastectomy either as primary preventative, or as secondary preventative, after breast cancer diagnosis. All participants underwent breast imaging at 6- to 12-month intervals after mastectomy. Data on subsequent breast cancer diagnosis and timing were collected and compared between the groups. Overall, 184 female mutation carriers (134 BRCA1, 45 BRCA2, 5 both BRCA genes) underwent bilateral mastectomy after initial breast cancer diagnosis, between April 1, 2009 and August 31, 2018. During a mean follow-up of 6.2 ± 4.2 years, 13 (7.06%) were diagnosed with breast cancer; 12 ipsilateral (range: 0.4-28.8 years) and 1 contralateral breast cancer, 15.9 years after surgery. On the contrary, among asymptomatic BRCA1 (n = 40) and BRCA2 (n = 13) mutation carriers who underwent primary risk-reducing mastectomy (mean age at surgery 39.5 ± 8.4 years); none has developed breast cancer after a mean follow-up of 5.4 ± 3.4 years. BRCA1/BRCA2 mutation carriers with prior disease who underwent risk-reducing mastectomy after breast cancer diagnosis are still prone for developing ipsi or contralateral breast cancer, and therefore may benefit from continues clinical and imaging surveillance, unlike BRCA1/BRCA2 mutation carriers who undergo primary preventative bilateral mastectomy.

Abstract
Breast cancer is the most commonly diagnosed cancer among women worldwide. Surgical removal of tumors is often necessary and many patients suffer complications due to subsequent breast reconstruction. A safe and effective breast reconstructive material is needed for patients recovering from surgical removal of small breast cancer tumors. Our lab has developed injectable collagen/tannic acid beads seeded with patient-derived preadipocytes for regeneration of healthy breast tissue in patients post-lumpectomy. Previous research indicates that the inclusion of tannic acid in the matrix imparts an anticancer property. This research seeks to determine the variables needed to control collagen/tannic acid bead diameter and seeded cell attachment, which are essential to proper bead implantation and function. We found that as tannic acid concentration increases within the beads, cell attachment decreases. Bead diameter is controlled by bead generator voltage, solution osmolality, the degree of cell attachment, and tannic acid concentrations. Higher voltages resulted in significant decrease in bead diameter. Collagen/tannic acid beads decreased in diameter when placed in solutions of increasing osmolality. Higher degrees of cell attachment across the surface of the beads were associated with a significant decrease in diameter. In beads made with high concentrations of tannic acid, bead diameter was found to decrease. Collagen/TA beads are a promising subdermal tissue regenerative matrix with anticancer activity as an alternative to simple lipofilling in breast reconstructive procedures. This study was conducted to better understand the properties of collagen/TA beads in order to improve injection efficacy and tissue regenerative activity.

Abstract
The association between immediate breast reconstruction (IBR)-related wound complications and breast cancer recurrence (BCR) remains uncertain. This study aimed to investigate the oncological outcomes in patients with wound complications following mastectomy and IBR. A comprehensive search was undertaken for all studies describing complications in patients with breast cancer following IBR. Studies were included if they reported on complications and investigated their relationship with BCR. A meta-analysis was performed using a random-effects model, with data presented as odds ratios and 95% confidence intervals. A total of 1418 patients from five studies were included in the final analysis. The mean age of patients included was 47.2 years. A total of 382 (26.9%) patients had postoperative complications following a majority of implant-based IBR (929/1418). A total of 158 (11.1%) recurrences, which included 63 locoregional and 106 distant recurrences, was noted at a mean follow-up of 66 months. Although there was an increase in recurrence rates in the complication group (n = 66/382; 17.3% vs. n = 92/1036; 8.9%), there was no significant association between complications and BCR (17.3% vs. 8.9%; P = .18) or mortality (3.6% vs. 2.3%; P = .15). Time to adjuvant therapy was significantly increased in patients with complications (mean difference, 8.69 days; range, 1.18-16.21 days; P = .02; I2 = 0.02). This meta-analysis demonstrated a higher incidence of wound complications following IBR and a statistically significant increased time to adjuvant therapy. However, this did not translate into adverse oncological outcomes in patients with breast cancer undergoing IBR.

Abstract
BACKGROUND Ramifications of postoperative complications on long-term survival after mastectomy are uncertain. METHODS Overall complications (Clavien-Dindo Grades I-IIIB) and wound complications were analyzed using the Kaplan-Meier method for impact on 5-year overall (OS) and disease-free survival (DFS). RESULTS A total of 378 patients underwent mastectomy alone (157, 41%) or mastectomy with reconstruction (221, 59%) for Stage I-III disease with a median follow-up of 5 years. Postoperative complications occurred in 186 patients (49%), requiring non-surgical (I/II = 83, 22%) or surgical (IIIa/IIIb = 103, 27%) management. Wound complications occurred in 140 patients (37%). Reconstruction was associated with a higher rate of complication (P < 0.001). Postoperative complications after mastectomy (with or without reconstruction) did not significantly affect OS or DFS. Wound complications also showed no significant effect on OS or DFS following mastectomy alone, or mastectomy with reconstruction. CONCLUSIONS Postoperative complications after mastectomy, with or without reconstruction, bear no significant impact on 5-year survival.

Abstract
BACKGROUND This systematic review investigated the impact of complications on long term outcomes for patients with primary invasive operable breast cancer. METHODS A systematic review was performed using appropriate keywords, and meta-analysis using a random effects model completed. RESULTS Ten retrospective cohort studies, including 37,657 patients were included. Five studies identified a relationship between wound complications, infection and pyrexia and recurrence or recurrence-free survival. Risk of recurrence, 1-year and 5-year recurrence-free survival and overall survival were related to complications, particularly for patients with poor Nottingham Prognostic Index. Five studies failed to demonstrate a relationship between complications and prognosis. Complication was found to significantly affect 5-year recurrence-free survival (HR 1.48 95 % CI 1.02-2.14, p = 0.04) but not recurrence (HR 2.39, 95 %CI 0.94-6.07, p = 0.07), with a high degree of heterogeneity amongst analysed studies (I2 = 95 %). DISCUSSION Further research is needed to quantify the effects of postoperative complication on prognosis following surgery for breast cancer.

Abstract
Breast cancer is the second most prevalent form of cancer in women worldwide, with surgery remaining the standard treatment. The adverse impact of the surgery remains controversial. It has been suggested that systemic factors during the postoperative period may increase the risk of recurrence, specifically surgical site infection (SSI). The aim of this review was to critically appraise current published literature regarding the influence of SSIs, after primary breast cancer surgery, on breast cancer recurrence, and to delve into potential links between these. This systematic review adopted two approaches: to identify the incidence rates and risk factors related to SSI after primary breast cancer surgery; and, secondly, to examine breast cancer recurrence following SSI occurrence. Ninety-nine studies with 484,605 patients were eligible in the SSI-focused searches, and 53 studies with 17,569 patients for recurrence-focused. There was a 13.07% mean incidence of SSI. Six-hundred and thirty-eight Gram-positive and 442 Gram-negative isolates were identified, with methicillin-susceptible Staphylococcus aureus and Escherichia coli most commonly identified. There were 2077 cases of recurrence (11.8%), with 563 cases of local recurrence, 1186 cases of distant and 25 cases which recurred both locally and distantly. Five studies investigated the association between SSI and breast cancer recurrence with three concluding that an association did exist. In conclusion, there is association between SSI and adverse cancer outcomes, but the cellular link between them remains elusive. Confounding factors of retrospective study design, surgery type and SSI definition make results challenging to compare and interpret. A standardized prospective study with appropriate statistical power is justified.

Abstract
Abstract
Background
Immediate breast reconstruction is safe from an oncological perspective, but the relatively high rate of postoperative complications raises oncological concerns. The present study aimed to evaluate the potential influence of postoperative complications after immediate breast reconstruction on breast cancer recurrence and survival.
Methods
Patients with breast cancer who had total mastectomy and immediate reconstruction between 2008 and 2013 were followed for at least 5 years. The impact of postoperative complications on oncological outcomes was assessed using multivariable Cox regression analyses.
Results
In total, 438 patients with a median follow-up of 82 months were analysed. Five-year local recurrence-free, disease-free and overall survival rates were 95·4, 93·1 and 98·4 per cent respectively. Postoperative complications developed in the operated breast in 120 patients (27·4 per cent) and at other sites (flap donor) in 30 patients (6·8 per cent). Development of breast complications was associated with significantly increased rate of recurrence compared with no complications (16·7 versus 5·9 per cent; P = 0·002). In multivariable analysis, patients with breast complications had significantly worse disease-free survival than those with no complications (hazard ratio (HR) 2·25; P = 0·015). This remained significant in patients who received adjuvant therapy without delay (8 weeks or less after surgery) (HR 2·45; P = 0·034).
Conclusion
Development of postoperative complications in the breast can have a negative impact on survival and recurrence after immediate reconstruction.

Abstract
BACKGROUND In various oncological conditions, complications correlate with diminished prognosis, however literature on soft tissue sarcomas is limited and inconclusive. The aim of this study was to assess risk factors and the oncologic impact of wound complications in primary extremity soft-tissue sarcomas. METHODS Patients with primary extremity soft tissue sarcomas without dissemination and with clear surgical margins (R0) were analyzed. Groups with and without wound complications were compared by univariate and multivariable analysis to identify risk factors. Uni- and multivariable analysis of factors associated with local recurrence free survival (LRFS), metastasis free survival (MFS) and disease specific survival (DSS) were performed. RESULTS 682 patients were included in the study, wound complications occurred in 94 patients (13.7%) within 90 days. Age, ASA-stage, high tumor size and grade, tumor location in the foot, neoadjuvant radiation therapy and operation time represented independent risk factors for wound complications. Patients with wound complications had a significantly worse estimated 5-year LRFS of 49.4 ± 6% versus 78.3 ± 2.1% and 5-year DSS of 77.9 ± 5.4% versus 89.1 ± 1.6%. Wound complications could be identified as an independent risk factor for worse LRFS (HR 2.68[CI 1.83-3.93], p < 0.001) and DSS (HR 1.79[CI 1.01-3.16], p = 0.046). CONCLUSION Wound complications after soft tissue sarcomas of the extremities are associated with worse local oncological outcome and survival. Patients with high risk of wound complications should be identified and strategies implemented to reduce surgical complications and possibly improve oncologic prognosis.

Abstract
The physiological stress response to surgery promotes wound healing and functional recovery and includes the activation of neural, inflammatory and proangiogenic signaling pathways. Paradoxically, the same pathways also promote metastatic spread and growth of residual cancer. Human and animal studies show that cancer surgery can increase survival, migration and proliferation of residual tumor cells. To secure the survival and growth of disseminated tumor cells, the formation of premetastatic niches in target organs involves a complex interplay between microenvironment, immune system, circulating tumor cells, as well as chemical mediators and exosomes secreted by the primary tumor. This review describes the current understanding of the early mechanisms of dissemination, as well as how surgery may facilitate disease progression.

Negative Impact of Wound Complications on Oncologic Outcome of Soft Tissue Sarcomas of the Chest Wall. Cancers (Basel) 2019; 12:cancers12010101.

Abstract
A link of complications with worse oncologic prognosis has been established for multiple malignancies, while the limited literature on soft-tissue sarcomas is inconclusive. The aim of this study was to examine risk factors and the oncologic impact of wound complications after curative resection of primary soft-tissue sarcomas of the chest wall. Patients with primary soft tissue sarcomas of the chest wall were identified. Groups with and without wound complications were compared by using univariate and multivariate analysis to identify risk factors. For patients with clear surgical margins (R0), univariate and multivariate analysis of factors associated with 5-year local recurrence free survival (LRFS), metastasis free survival (MFS), and disease specific survival (DSS) were performed. A total of 102 patients were included in the study. Wound complications occurred in 11 patients (10.8%) within 90 days. Cardiovascular morbidity and operation time represented independent risk factors for wound complications. In 94 patients with clear surgical margins, those with wound complications had an estimated 5-year LRFS of 30% versus 72.6% and a 5-year DSS of 58.3% versus 82.1%. Wound complications could be identified as an independent predictor for worse LRFS and DSS. Patients with a high risk of wound complications should be identified and strategies implemented to reduce surgical complications and possibly improve oncologic prognosis.

Abstract
After mastectomy, breast reconstruction is increasingly performed using autologous tissue with the aim of improving quality of life. During this procedure, autologous tissue is excised, relocated, and reattached using microvascular anastomoses at the site of the extirpated breast. The period during which the tissue is ex vivo may allow genetic modification without any systemic exposure to the vector. Could such access permit delivery of therapeutic agents using the tissue flap as a vehicle? Such delivery may be more targeted and oncologically efficient than systemic therapy, and avoid systemic complications. The cytokine IFNγ has antitumor effects, and systemic toxicity could be circumvented by localized delivery of the IFNγ gene via gene therapy to autologous tissue used for breast reconstruction, which then releases IFNγ and exerts antitumor effects. In a rat model of loco-regional recurrence (LRR) with MADB-106-Luc and MAD-MB-231-Luc breast cancer cells, autologous tissue was transduced ex vivo with an adeno-associated viral vector encoding IFNγ. The "Therapeutic Reconstruction" released IFNγ at the LRR site and eliminated cancer cells, significantly decreased tumor burden, and increased survival compared with sham reconstruction (P <0.05). Mechanistically, localized IFNγ immunotherapy stimulated M1 macrophages to target cancer cells within the regional confines of the modified tumor environment. This concept of "Therapeutic Breast Reconstruction" using ex vivo gene therapy of autologous tissue offers a new application for immunotherapy in breast cancer with a dual therapeutic effect of both reconstructing the ablative defect and delivering local adjuvant immunotherapy.

Abstract
Background Immediate breast reconstruction (IBR) is routinely offered to improve quality-of-life for women requiring mastectomy, but there are concerns that more complex surgery may delay adjuvant oncological treatments and compromise long-term outcomes. High-quality evidence is lacking. The iBRA-2 study aimed to investigate the impact of IBR on time to adjuvant therapy. Methods Consecutive women undergoing mastectomy ± IBR for breast cancer July–December, 2016 were included. Patient demographics, operative, oncological and complication data were collected. Time from last definitive cancer surgery to first adjuvant treatment for patients undergoing mastectomy ± IBR were compared and risk factors associated with delays explored. Results A total of 2540 patients were recruited from 76 centres; 1008 (39.7%) underwent IBR (implant-only [n = 675, 26.6%]; pedicled flaps [n = 105,4.1%] and free-flaps [n = 228, 8.9%]). Complications requiring re-admission or re-operation were significantly more common in patients undergoing IBR than those receiving mastectomy. Adjuvant chemotherapy or radiotherapy was required by 1235 (48.6%) patients. No clinically significant differences were seen in time to adjuvant therapy between patient groups but major complications irrespective of surgery received were significantly associated with treatment delays. Conclusions IBR does not result in clinically significant delays to adjuvant therapy, but post-operative complications are associated with treatment delays. Strategies to minimise complications, including careful patient selection, are required to improve outcomes for patients.

Abstract
Background Studies report that incision management with closed incision negative pressure therapy (ciNPT) may provide clinical benefits, including protecting surgical incisions, for postsurgical closed incisions (eg, orthopedic, sternotomy, and colorectal). This retrospective analysis compared postoperative outcomes in patients who received ciNPT versus standard of care (SOC) for incision management after breast reconstruction postmastectomy. Methods Patient demographics, chemotherapy exposure, surgical technique, ciNPT use, number of drains, time to drain removal, and 90-day postoperative complication rates were analyzed from records of 356 patients (ciNPT = 177, SOC = 179) with 665 closed breast incisions (ciNPT = 331, SOC = 334). Results Overall complication rate was 8.5% (28/331) in ciNPT group compared with 15.9% (53/334) in SOC group (P = 0.0092). Compared with the SOC group, the ciNPT group had significantly lower infection rates [7/331 (2.1%) versus 15/334 (4.5%), respectively; P = 0.0225], dehiscence rates [8/331 (2.4%) versus 18/334 (5.4%), respectively; P = 0.0178], necrosis rates [17/331 (5.1%) versus 31/334 (9.3%), respectively; P = 0.0070], and seroma rates [6/331 (1.8%) versus 19/334 (5.7%), respectively; P = 0.0106]. The ciNPT group required significantly fewer returns to operating room compared with the SOC group [8/331 (2.4%) versus 18/334 (5.4%), respectively; P = 0.0496]. Time to complete drain removal per breast for ciNPT versus SOC groups was 9.9 versus 13.1 days (P < 0.0001), respectively. Conclusions Patients who received ciNPT over closed incisions following postmastectomy breast reconstruction experienced a shorter time to drain removal and significantly lower rates of infection, dehiscence, necrosis, and seromas, compared with the SOC group. Randomized controlled studies are needed to corroborate the findings in our study.

Abstract
Background Peri-operative inflammation has been extensively highlighted in cancer patients as detrimental. Treatment strategies to improve survival for cancer patients through targeting peri-operative inflammation have yet to be devised. Methods We conducted a multi-centre, randomised controlled clinical trial using Taurolidine in non-metastatic colon cancer patients. Patients were randomly assigned to receive Taurolidine or a placebo. The primary endpoint for the study was the mean difference in day 1 IL-6 levels. Secondary clinical endpoints included rates of post-operative infections and tumor recurrence. Results A total of 293 patients were screened for trial inclusion. Sixty patients were randomised. Twenty-eight patients were randomised to placebo and 32 patients to Taurolidine. IL-6 levels were equivalent on day 1 post-operatively in both groups. However, IL-6 levels were significantly attenuated over the 7 day study period in the Taurolidine group compared to placebo (p = 0.04). In addition, IL-6 levels were significantly lower at day 7 in the Taurolidine group (p = 0.04). There were 2 recurrences in the placebo group at 2 years and 1 in the Taurolidine group. The median time to recurrence was 19 months in the Placebo group and 38 months in the Taurolidine group (p = 0.27). Surgical site infection was reduced in the Taurolidine treated group (p = 0.09). Conclusion Peri-operative use of Taurolidine significantly attenuated circulating IL-6 levels in the initial 7 day post-operative period in a safe manner. Future studies are required to establish the impact of IL-6 attenuation on survival outcomes in colon cancer. Trial registration The trial was registered with EudraCT (year = 2008, registration number = 005570–12) and ISRCTN (year = 2008, registration number = 77,829,558).

Abstract
OBJECTIVE: There are several limitations with current methods of breast volume measurement; principally relating to assumption of fixed shape forms. This study, utilizing computer aided volume estimates, developed a new method using the digital mapping of breast area and compares results to existing techniques of breast volume measurement and actual breast volume. METHODS: 50 consecutive breast cancer patients had breast volume calculated from mammograms [craniocaudal (CC) and mediolateral oblique views]; using breast height, width, radius, area and compression thickness. Area was recorded using cursor measurement tool for AGFA® Impax™6 software. The new volumetric estimation is based on the basic formula for the volume of a solid. The technique was compared with three known breast volume estimation techniques. Subsequently, 15 patients undergoing mastectomy had pre-op breast volume calculated using this new method and 3 existing techniques; values were compared to fresh mastectomy weights/volumes. RESULTS: 50 patients, mean age 63.2 ± 14.4 (range 38-88) had breast volume estimation. The CC view appears to provide the best correlation with existing techniques. Scatterplots show a significant correlation of all the methods with the digital breast volume estimation method. Mastectomy volume compared with four breast volume techniques in n = 15, confined to the CC, shows good correlation between the digital technique and real volume. Scatterplots show significant correlation between digital breast volume estimation and mastectomy weight. CONCLUSION: This study provided a novel simple tool to estimate breast volume in patients. ADVANCES IN KNOWLEDGE: This may aid in planning cosmetic outcome and oncoplastic approaches in breast cancer and breast reduction surgery.

Abstract
Breast reconstruction proceeding cancer treatment carries risk, regardless of the type of surgery. From fat grafting, to flap placement, to implants, there is no guarantee that reconstruction will not stimulate breast cancer recurrence. Research in this field is clearly divided into two parts: scientific interventional studies and clinical retrospective evidence. The reconstructive procedure offers hypoxia, a wound microenvironment, bacterial load, adipose derived stem cells; agents shown experimentally to cause increased cancer cell activity. This is compelling scientific evidence which serves to bring uncertainty and fear to the reconstructive procedure. In the absence of clinical evidence, this laboratory literature landscape is now informing surgical choices. Curiously, clinical studies have not shown a clear link between breast cancer recurrence and reconstructive surgery. Where does that leave us? This review aims to analyze the science and the surgery, thereby understanding the oncological fear which accompanies breast cancer reconstruction.

Abstract
Surgery is a mainstay treatment for patients with solid tumours. However, despite surgical resection with a curative intent and numerous advances in the effectiveness of (neo)adjuvant therapies, metastatic disease remains common and carries a high risk of mortality. The biological perturbations that accompany the surgical stress response and the pharmacological effects of anaesthetic drugs, paradoxically, might also promote disease recurrence or the progression of metastatic disease. When cancer cells persist after surgery, either locally or at undiagnosed distant sites, neuroendocrine, immune, and metabolic pathways activated in response to surgery and/or anaesthesia might promote their survival and proliferation. A consequence of this effect is that minimal residual disease might then escape equilibrium and progress to metastatic disease. Herein, we discuss the most promising proposals for the refinement of perioperative care that might address these challenges. We outline the rationale and early evidence for the adaptation of anaesthetic techniques and the strategic use of anti-adrenergic, anti-inflammatory, and/or antithrombotic therapies. Many of these strategies are currently under evaluation in large-cohort trials and hold promise as affordable, readily available interventions that will improve the postoperative recurrence-free survival of patients with cancer.

Abstract
INTRODUCTION Mastectomy with immediate reconstruction is associated with increased complications when compared with mastectomy without reconstruction. Postoperative complications have been associated with worse oncologic outcome in other cancers. We examined the association between postoperative complications after immediate reconstruction and oncologic outcome. METHODS This retrospective study included all women undergoing mastectomy and immediate alloplastic reconstruction for breast cancer between the years 2009 and 2016. Data collected included demographics, cancer and treatment characteristics, type of surgery, postoperative complications, and outcome. Association between postoperative complications and oncologic outcome was examined using Cox regression analysis. RESULTS Between January 2009 and December 2016, 227 women underwent mastectomy with immediate alloplastic reconstruction. One hundred eighty-six (82%) were done for breast cancer. Most (148; 80%) had infiltrating carcinoma. The mean age was 48.8 years (range, 21-77 years). Forty-seven (25%) had a previous history of radiation. Fifty-four (29%) had neoadjuvant treatment. Complications occurred in 83 (45%) of the women. Fifty-five (30%) needed revisional surgery (closure of wound, debridement, exchange or removal of implant, and evacuation of hematoma). Complications were associated with older age and previous radiation history (57% vs. 40% in women with no previous radiation; P = .04). The mean follow-up was 1138 days. Twenty-five (12%) women developed recurrence during follow-up. There was no association between presence of postoperative complications and recurrence of cancer. CONCLUSIONS Postoperative complications were not associated with worse oncologic outcome in this study. The study may be limited by the relatively short follow-up.

Abstract
BACKGROUND Breast reconstruction is an important component of multidisciplinary breast cancer management. The practice of breast reconstruction after mastectomy has evolved significantly in the past decade as a result of both increasing mastectomy rates and advances in reconstructive strategy. These changes have significantly influenced the contemporary surgical management of breast cancer. The aim of this study was to examine trends in breast reconstruction after mastectomy in an Irish population. METHODS Data were reviewed from a database of all patients who had mastectomy with or without breast reconstruction at Galway University Hospital, a tertiary breast cancer referral centre, between 2004 and 2014. Trends in breast reconstruction after mastectomy were explored with respect to patient demographics, clinicopathological features, and neoadjuvant and adjuvant therapy. RESULTS Of 1303 patients who underwent mastectomy during interval studied, 706 (54.2 per cent) had breast reconstruction after mastectomy. In 629 patients (89·1 per cent), breast reconstruction was performed in the immediate setting. Reconstruction rates increased over time from 20·5 per cent in 2004 to 44·7 per cent in 2014. Reconstruction was more commonly performed in younger patients and those with benign, in situ and early-stage disease. A negative relationship between radiotherapy and reconstruction was observed. A pedicled flap with or without an implant was the most commonly used reconstructive approach in patients receiving radiotherapy. CONCLUSION Breast reconstruction after mastectomy has become the standard of care in the surgical treatment of breast cancer. Recent trends show a transition favouring implant-based approaches.

Abstract
Background: We report the first meta-analysis on the impact of prophylactic use of a specific design of negative pressure wound therapy (NPWT) device on surgical site complications. Methods: Articles were identified in which the specific single-use NPWT device (PICO⋄, Smith & Nephew) was compared with standard care for surgical site infection (SSI), dehiscence, or length of stay (LOS). Risk ratio (RR) ±95% confidence interval (CI) (SSI; dehiscence) or mean difference in LOS ±95% CI was calculated using RevMan v5.3. Results: There were 1863 patients (2202 incisions) represented by 16 articles. Among 10 randomized studies, there was a significant reduction in SSI rate of 51% from 9.7% to 4.8% with NPWT intervention (RR 0.49 [95% CI 0.34–0.69] p < 0.0001). There were six observational studies assessing reduction in SSI rate of 67% from 22.5% to 7.4% with NPWT (RR 0. 32 [95% CI 0.18–0.55] p < 0.0001). Combining all 16 studies, there was a significant reduction in SSI of 58% from 12.5% to 5.2% with NPWT (RR 0.43 [95% CI 0.32–0.57] p < 0.0001). Similar effects were seen irrespective of the kind of surgery (orthopedic, abdominal, colorectal, or cesarean section), although the numbers needed to treat (NNT) were lower in operations with higher frequencies of complications. There was a significant reduction in dehiscence from 17.4% to 12.8% with NPWT (RR 0.71 [95% CI 0.54–0.92] p < 0.01). The mean reduction in hospital LOS by NPWT was also significant (−0.47 days [95% CI −0.71 to −0.23] p < 0.0001). Conclusions: The significant reduction in SSI, wound dehiscence, and LOS on the basis of pooled data from 16 studies shows a benefit of the PICO single-use NPWT system compared with standard care in closed surgical incisions.

Abstract
BACKGROUND AND OBJECTIVES The impact of regional anesthesia on breast cancer recurrence is controversial. We tested the hypothesis that the use of paravertebral block (PVB) analgesia during breast cancer surgery prolongs the recurrence-free survival (RFS) and overall survival (OS) of women with breast cancer. METHODS Seven hundred ninety-two women with nonmetastatic breast cancer were included in this retrospective study. Patients were divided based on the administration of PVB analgesia for mastectomy surgeries. One hundred ninety-eight (25%) were given a PVB, the remainder were treated with opioid-based analgesia. Propensity score matching was developed using several variables. Univariate and multivariate analyses were used to assess the impact of PVB analgesia on RFS and OS. RESULTS The median follow-up times for RFS and OS were 5.8 and 6 years, respectively. In the propensity score matching model, a total of 396 women were included in each group of treatment (non-PVB group, n = 198 vs PVB group, n = 198). As expected, the fentanyl consumption was significantly lower in PVB (122.8 ± 77.85 μg) patients than non-PVB subjects (402.23 ± 343.8 μg). Other variables were not statistically significant. After adjusting for several important covariates, the analysis indicated that the use of PVB is not associated with a significant change in RFS [1.60 (0.81-3.16), P = 0.172] or OS [1.28 (0.55-3.01)] survival. DISCUSSION This retrospective study does not support the hypothesis that the use of regional analgesia is associated with longer survival after surgery for breast cancer.
