Abstract
BACKGROUND Many patients who have undergone surgery experience persistent pain after breast cancer treatment (PPBCT). These symptoms often remain unnoticed by treating physician(s), and the pathophysiology of PPBCT remains poorly understood. The purpose of this study was to determine prevalence of PPBCT and examine the association between PPBCT and various patient, tumor, and treatment characteristics. PATIENTS AND METHODS We conducted a questionnaire-based cross-sectional study enrolling patients with breast cancer treated at Máxima Medical Center between 2005 and 2016. PPBCT was defined as pain in the breast, anterior thorax, axilla, and/or medial upper arm that persists for at least 3 months after surgery. Tumor and treatment characteristics were derived from the Dutch Cancer Registry and electronic patient files. RESULTS Between February and March 2019, a questionnaire was sent to 2022 women, of whom 56.5% responded. Prevalence of PPBCT among the responders was 37.9%, with 50.8% reporting moderate to severe pain. Multivariable analyses showed that women with signs of anxiety, depression or a history of smoking had a higher risk of experiencing PPBCT. Women aged 70 years or older at diagnosis were significantly less likely to report PPBCT compared with younger women. No significant association was found between PPBCT and treatment characteristics, including type of axillary surgery and radiotherapy. CONCLUSIONS A considerable percentage of patients with breast cancer experience PPBCT. Women with signs of anxiety or depression and women with a history of smoking are more likely to report PPBCT. Further research is required to understand the underlying etiology and to improve prevention and treatment strategies for PPBCT.

Postoperative Antibiotics Confer No Protective Association After Fat Grafting for Breast Reconstruction. Ann Plast Surg 2023:00000637-990000000-00160.

Abstract
INTRODUCTION Autologous fat grafting after breast reconstruction is a commonly used technique to address asymmetry and irregularities in breast contour. While many studies have attempted to optimize patient outcomes after fat grafting, a key postoperative protocol that lacks consensus is the optimal use of perioperative and postoperative antibiotics. Reports suggest that complication rates for fat grafting are low relative to rates after reconstruction and have been shown to not be correlated to antibiotic protocol. Studies have additionally demonstrated that the use of prolonged prophylactic antibiotics do not lower the complication rates, stressing the need for a more conservative, standardized antibiotic protocol. This study aims to identify the optimal use of perioperative and postoperative antibiotics that optimizes patient outcomes. METHODS Patients in the Optum Clinformatics Data Mart who underwent all billable forms of breast reconstruction followed by fat grafting were identified via Current Procedural Terminology codes. Patients meeting inclusion criteria had an index reconstructive procedure at least 90 days before fat grafting. Data concerning these patient's demographics, comorbidities, breast reconstructions, perioperative and postoperative antibiotics, and outcomes were collected via querying relevant reports of Current Procedural Terminology; International Classification of Diseases, Ninth Revision; International Classification of Diseases, Tenth Revision; National Drug Code Directory, and Healthcare Common Procedure Coding System codes. Antibiotics were classified by type and temporal delivery: perioperatively or postoperatively. If a patient received postoperative antibiotics, the duration of antibiotic exposure was recorded. Outcomes analysis was limited to the 90-day postoperative period. Multivariable logistic regression was performed to ascertain the effects of age, coexisting conditions, reconstruction type (autologous or implant-based), perioperative antibiotic class, postoperative antibiotic class, and postoperative antibiotic duration on the likelihood of any common postoperative complication occurring. All statistical assumptions made by logistic regression were met successfully. Odds ratios and corresponding 95% confidence intervals were calculated. RESULTS From more than 86 million longitudinal patient records between March 2004 and June 2019, our study population included 7456 unique records of reconstruction-fat grafting pairs, with 4661 of those pairs receiving some form of prophylactic antibiotics. Age, prior radiation, and perioperative antibiotic administration were consistent independent predictors of increased all-cause complication likelihood. However, administration of perioperative antibiotics approached a statistically significant protective association against infection likelihood. No postoperative antibiotics of any duration or class conferred a protective association against infections or all-cause complications. CONCLUSIONS This study provides national, claims-level support for antibiotic stewardship during and after fat grafting procedures. Postoperative antibiotics did not confer a protective benefit association against infection or all-cause complication likelihood, while administering perioperative antibiotics conferred a statistically significant increase in the likelihood that a patient experienced postoperative complication. However, perioperative antibiotics approach a significant protective association against postoperative infection likelihood, in line with current guidelines for infection prevention. These findings may encourage the adoption of more conservative postoperative prescription practices for clinicians who perform breast reconstruction, followed by fat grafting, reducing the nonindicated use of antibiotics.

Abstract
There is undisputable benefit in translating basic science research concretely into clinical practice, and yet, the vast majority of therapies and treatments fail to achieve approval. The rift between basic research and approved treatment continues to grow, and in cases where a drug is granted approval, the average time from initiation of human trials to regulatory marketing authorization spans almost a decade. Albeit with these hurdles, recent research with deferoxamine (DFO) bodes significant promise as a potential treatment for chronic, radiation-induced soft tissue injury. DFO was originally approved by the Food and Drug Administration (FDA) in 1968 for the treatment of iron overload. However, investigators more recently have posited that its angiogenic and antioxidant properties could be beneficial in treating the hypovascular and reactive-oxygen species-rich tissues seen in chronic wounds and radiation-induced fibrosis (RIF). Small animal experiments of various chronic wound and RIF models confirmed that treatment with DFO improved blood flow and collagen ultrastructure. With a well-established safety profile, and now a strong foundation of basic scientific research that supports its potential use in chronic wounds and RIF, we believe that the next steps required for DFO to achieve FDA marketing approval will include large animal studies and, if those prove successful, human clinical trials. Though these milestones remain, the extensive research thus far leaves hope for DFO to bridge the gap between bench and wound clinic in the near future.

The comparison of transforming growth factor beta-1 serum levels in early-stage breast cancer patients treated with external beam whole breast irradiation plus boost versus interstitial brachytherapy accelerated partial breast irradiation. Brachytherapy 2022; 21:748-753. [PMID: 36167654 DOI: 10.1016/j.brachy.2022.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 08/17/2022] [Accepted: 08/18/2022] [Indexed: 12/14/2022]
Abstract
PURPOSE Transforming growth factor beta-1 (TGF-β1) is a profibrotic cytokine used as an early biomarker to develop radiation-induced fibrosis (RIF). This study aimed to compare TGF-β1 serum levels in early-stage breast cancer patients treated with whole-breast radiation therapy (WBRT) plus boost versus accelerated partial breast irradiation (APBI) using multicatheter interstitial brachytherapy. METHODS AND MATERIALS This clinical trial study was conducted on 20 women with early-stage breast cancer after breast-conserving surgery candidate for adjuvant radiotherapy in Golestan hospital, Ahvaz, in 2021. In one group APBI with high-dose-rate brachytherapy (n = 10), the other group WBRT with external beam radiation plus boost (n = 10) was performed. Serum level of TGF-β1 was evaluated before radiotherapy, immediately after the end of radiotherapy and three months after the end of radiotherapy by Enzyme-linked immunosorbent assay technique (ELISA). RESULTS Median serum TGF-β1 level before radiotherapy was not significantly different between the two groups (p = 0.971). In both APBI and WBRT groups, serum TGF-β1 levels significantly decreased immediately after radiotherapy compared to before treatment (p = 0.005 and p = 0.007, respectively); But three months after radiotherapy, serum TGF-β1 levels increased significantly in the WBRT group (40.50 to 77.41 pg/mL; p = 0.017), while no significant change was observed in the APBI group (24.75 to 30.50 pg/mL; p = 0.332). CONCLUSIONS Higher TGF-β1 values in the WBRT group after radiotherapy can be used as an early and vital biomarker in this treatment, and this data may corroborate links between TGF-beta1 and fibrosis and fibrosis rates between APBI and WBRT; It also shows the preference for using the brachytherapy technique in this group of patients. However, due to the small number of samples, definitive conclusions require further prospective studies.

Abstract
Purpose Radiation therapy can affect normal tissues in patients with breast cancer, causing adverse effects such as fibrosis. Although there are several interventions for radiation-induced fibrosis, the efficacy of these procedures is still unclear. The purpose of this review is to evaluate the efficacy of interventions for radiation-induced fibrosis in patients with breast cancer. Methods and Materials This is a systematic review of randomized clinical trials. Studies that compared any intervention for fibrosis to another intervention, placebo, or no intervention were included. Outcomes assessed were fibrosis, adverse events, quality of life, treatment adherence, pain, and functionality. Results A total of 2501 publications were found, and 7 studies were selected because they met the inclusion criteria. The interventions for fibrosis were pentoxifylline and vitamin E, grape seed extract, kinesiotherapy, and endermotherapy. The results showed great heterogeneity in the treatment protocols for radiation-induced fibrosis in patients with breast cancer and in their evaluation metrics. The meta-analyses showed no benefit in using pentoxifylline and vitamin E compared with placebo or no intervention (standardized mean difference: −0.30; 95% confidence interval, −0.79 to 0.20; P = .24 [very low evidence]) compared with placebo and vitamin E (standardized mean difference: −0.09; 95% confidence interval, −0.66 to 0.49; P = .77 [moderate evidence]), respectively, assessed by the Late Effects Normal Tissue Task Force–Subjective, Objective, Management, and Analytic (LENT-SOMA) scoring scale. Conclusions The effectiveness of these interventions for the treatment of radiation-induced fibrosis in patients with breast cancer could not be determined. Although isolated studies show significant results favorable to the experimental groups, caution should be exercised in these findings because of the small number, small sample size, and high risk of bias presented by some of the included studies, which makes the recommendation for clinical practice still weak.

Effects of free range-of-motion upper limb exercise based on mirror therapy on shoulder function in patients after breast cancer surgery: study protocol for a randomized controlled trial. Trials 2021; 22:815. [PMID: 34789309 PMCID: PMC8596341 DOI: 10.1186/s13063-021-05789-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2021] [Accepted: 11/03/2021] [Indexed: 11/17/2022] Open
Abstract
Background Shoulder function complications are common after treatment for breast cancer. Quite a few survivors still report a limited shoulder range of motion, even though the free range-of-motion upper limb exercise is helpful to restore shoulder function. Mirror therapy (MT) is a classical and effective rehabilitation technique to recover motor and sensory function for the limbs; in addition, studies have reported that MT has an influence on patients with shoulder functional dysfunction including increasing shoulder range of motion, improving shoulder function scores, and decreasing pain scores. Here, we describe a protocol of a randomized controlled trial to explore if free range-of-motion upper limb exercise based on MT has efficacy on shoulder function in survivors after surgery of breast cancer. Methods/design This is a prospective, single-blind, two-arm randomized controlled trial. An estimated 70 participants will be randomly allocated to (1) the MT group or (2) the control group. The participants in the control group receive free range-of-motion upper limb exercise, and participants in the MT group will engage in free range-of-motion upper limb exercise based on MT. The intervention will start on the first day after surgery and be completed at 8 weeks after surgery. The primary outcome in this protocol is shoulder range of motion (ROM), while the Constant-Murley Score (CMS); Disability of the Arm, Shoulder, and Hand Questionnaire (DASH); Tampa Scale of Kinesiophobia (13-item TSK); visual analog scale (VAS); grip strength; arm circumference; and lymphedema are the secondary outcomes. Assessment will be conducted before allocation (baseline) and at 2 weeks, 4 weeks, and 8 weeks after surgery. Discussion Based on the results that MT has an influence on shoulder function immediately after intervention in patients without nerve injury, this randomized controlled trial is to observe the efficacy of MT on shoulder function after a long-term intervention in breast cancer survivors. We look forward to the innovation of this study for both breast cancer rehabilitation and MT. Trial registration Chinese Clinical Trial Registry (ChiCTR) ChiCTR2000033080.

Signalling by lysophosphatidate and its health implications. Essays Biochem 2020; 64:547-563.

Abstract
AbstractExtracellular lysophosphatidate (LPA) signalling is regulated by the balance of LPA formation by autotaxin (ATX) versus LPA degradation by lipid phosphate phosphatases (LPP) and by the relative expressions of six G-protein-coupled LPA receptors. These receptors increase cell proliferation, migration, survival and angiogenesis. Acute inflammation produced by tissue damage stimulates ATX production and LPA signalling as a component of wound healing. If inflammation does not resolve, LPA signalling becomes maladaptive in conditions including arthritis, neurologic pain, obesity and cancers. Furthermore, LPA signalling through LPA1 receptors promotes fibrosis in skin, liver, kidneys and lungs. LPA also promotes the spread of tumours to other organs (metastasis) and the pro-survival properties of LPA explain why LPA counteracts the effects of chemotherapeutic agents and radiotherapy. ATX is secreted in response to radiation-induced DNA damage during cancer treatments and this together with increased LPA1 receptor expression leads to radiation-induced fibrosis. The anti-inflammatory agent, dexamethasone, decreases levels of inflammatory cytokines/chemokines. This is linked to a coordinated decrease in the production of ATX and LPA1/2 receptors and increased LPA degradation through LPP1. These effects explain why dexamethasone attenuates radiation-induced fibrosis. Increased LPA signalling is also associated with cardiovascular disease including atherosclerosis and deranged LPA signalling is associated with pregnancy complications including preeclampsia and intrahepatic cholestasis of pregnancy. LPA contributes to chronic inflammation because it stimulates the secretion of inflammatory cytokines/chemokines, which increase further ATX production and LPA signalling. Attenuating maladaptive LPA signalling provides a novel means of treating inflammatory diseases that underlie so many important medical conditions.

Dexamethasone Attenuates X-Ray-Induced Activation of the Autotaxin-Lysophosphatidate-Inflammatory Cycle in Breast Tissue and Subsequent Breast Fibrosis. Cancers (Basel) 2020; 12:cancers12040999. [PMID: 32325715 PMCID: PMC7226295 DOI: 10.3390/cancers12040999] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 04/14/2020] [Accepted: 04/15/2020] [Indexed: 02/06/2023] Open
Abstract
We recently showed that radiation-induced DNA damage in breast adipose tissue increases autotaxin secretion, production of lysophosphatidate (LPA) and expression of LPA1/2 receptors. We also established that dexamethasone decreases autotaxin production and LPA signaling in non-irradiated adipose tissue. In the present study, we showed that dexamethasone attenuated the radiation-induced increases in autotaxin activity and the concentrations of inflammatory mediators in cultured human adipose tissue. We also exposed a breast fat pad in mice to three daily 7.5 Gy fractions of X-rays. Dexamethasone attenuated radiation-induced increases in autotaxin activity in plasma and mammary adipose tissue and LPA1 receptor levels in adipose tissue after 48 h. DEX treatment during five daily fractions of 7.5 Gy attenuated fibrosis by ~70% in the mammary fat pad and underlying lungs at 7 weeks after radiotherapy. This was accompanied by decreases in CXCL2, active TGF-β1, CTGF and Nrf2 at 7 weeks in adipose tissue of dexamethasone-treated mice. Autotaxin was located at the sites of fibrosis in breast tissue and in the underlying lungs. Consequently, our work supports the premise that increased autotaxin production and lysophosphatidate signaling contribute to radiotherapy-induced breast fibrosis and that dexamethasone attenuated the development of fibrosis in part by blocking this process.
