Effect of magnesium sulfate with ketamine infusions on intraoperative and postoperative analgesia in cancer breast surgeries: a randomized double-blind trial

Abstract Background Opioids are the cornerstone in managing postoperative pain; however, they have many side effects. Ketamine and Magnesium (Mg) are NMDA receptor antagonists used as adjuvant analgesics to decrease postoperative opioid consumption. Objective We assumed that adding Mg to ketamine infusion can improve the intraoperative and postoperative analgesic efficacy of ketamine infusion alone in cancer breast surgeries. Methods Ninety patients aged between 18 and 65 years and undergoing elective cancer breast surgery were included in this prospective randomized, double-blind study. Group K received ketamine 0.5 mg.kg-1 bolus then 0.12 mg.kg-1.h-1 infusion for the first 24 hours postoperatively. Group KM: received ketamine 0.5 mg.kg-1 and Mg sulfate 50 mg.kg-1, then ketamine 0.12 mg.kg-1.h-1 and Mg sulfate 8 mg.kg-1.h-1 infusions for the first 24 hours postoperative. The primary outcome was the morphine consumption in the first 24 hours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. Results Group KM had less postoperative opioid consumption (14.12 ± 5.11 mg) than Group K (19.43 ± 6.8 mg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. Conclusion Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

Use of the serratus anterior fascia in immediate implant-based breast reconstruction

Using the serratus anterior fascia may be a safe and effective option to recreate the lateral breast profile during subpectoral breast reconstruction, with minimal functional impact on the donor site. However, the literature is scarce when it comes to studies on this fascia flap in implant-based reconstruction. This article aimed to review the use of the serratus anterior fascia in immediate implant-based breast reconstruction, searching the electronic databases PubMed, Embase, Lilacs, and SciELO. The search was carried out by combining the following keywords: 'breast reconstruction' and 'serratus anterior fascia'. In the Pubmed and Embase databases, the search yielded a total of 12 and 15 articles, respectively, of which seven were selected according to the scope of this article. We found no studies on serratus anterior fascia and breast reconstruction in the Lilacs and SciELO databases. All works have results favorable for the use of the serratus anterior fascia flap and agree that this technique can be considered in the algorithm for the coverage of the inferolateral portion during subpectoral breast reconstruction

Erysipelas after surgery for breast cancer: a real-world cohort

Erysipelas is often related to lymphedema, which can occur in up to 60% of cases, with advanced age, radiotherapy, tumor extension, surgical approach, and infections as risk factors. The aim of this study was to present and discuss a series of cases of erysipelas after breast cancer surgery treated in a private mastology clinic over the past ten years. This is a retrospective horizontal cohort study in which we selected all cases of erysipelas after breast cancer surgery from 2009 to 2019. The following were evaluated: number of patients treated with a diagnosis of breast carcinoma with axillary approach, age, surgery performed, adjuvant treatment and treatment of erysipelas, presence of lymphedema, and measurement of circumferences between both arms and associated diseases. A total of 12 cases of breast cancer were treated. In 66.66% of cases, a radical axillary lymphadenectomy was performed, and in 16.66% of cases, only a sentinel lymph node investigation was performed. The average age was 67.6 years. Erysipelas appeared, on average, 43 months after cancer diagnosis. Two deaths were reported due to severe erysipelas leading to sepsis. More studies are still needed on the subject. Of the 12 cases in this study, eight (66.66%) were associated with lymphedema. Only two (16.66%) of the patients in this group who developed erysipelas were not submitted to axillary dissection. The treatment for 50% of the participants in this research was with penicillin G benzathine. There were three relapses, and two patients died during the research period

Efficacy of serratus anterior plane block versus thoracic paravertebral block for postoperative analgesia after breast cancer surgery - a randomized trial

Abstract Background Breast cancer surgery is associated with considerable acute post-surgical pain and restricted mobility. Various regional and neuraxial anesthesia techniques have been used to alleviate post-mastectomy pain. Ultrasound-guided serratus anterior plane block (SAPB) has been considered a simple and safe technique. This randomized control study was performed to compare the efficacy of SAPB with the thoracic paravertebral block (TPVB) for postoperative analgesia after breast cancer surgery. Methods A total of 40 adult ASA physical status I - II female patients undergoing radical mastectomy were randomly allocated into two groups to receive either ultrasound-guided TPVB or SAPB with 0.4 mL.kg-1 0.5% ropivacaine, 30 min before surgery. All patients received standardized general anesthesia for surgery. Injection diclofenac and tramadol were used for postoperative rescue analgesia. The time to first rescue analgesia, total analgesic consumption in the first 24 hours, postoperative pain scores, and any adverse effects were recorded. Results The time to first rescue analgesia was significantly longer in the SAPB group (255.3 ± 47.8 min) as compared with the TPVB group (146.8 ± 30.4 min) (p< 0.001). Total diclofenac consumption in 24 hours was also less in the SAPB group (138.8 ± 44.0 mg vs 210.0 ± 39.2 mg in SAPB and TPVB group respectively, p< 0.001). Postoperative pain scores were significantly lower in the SAPB group as compared with TPVB group (p< 0.05). The incidence of PONV was also less in the SAPB group (p= 0.028). No block-related adverse effects were reported. Conclusion We found that the serratus anterior plane block was more effective than the thoracic paravertebral block for postoperative analgesia after breast cancer surgery.

Resulting in a technique of great safety, versatile, with little sequel in the donor area, and short surgical time

Aesthetic assessment of breast reconstruction in the eyes of plastic surgeons versus nonplastic physicians

SUMMARY OBJECTIVE: The aim of this study was to evaluate the perception of the aesthetic result of breast reconstruction surgery from the perspective of plastic surgeons compared with physicians who are not specialists in plastic surgery. METHODS: Twenty patients who underwent breast reconstruction after mastectomy had their aesthetic results evaluated by 16 plastic surgeons and 16 nonplastic physicians, yielding a total of 620 ratings (320 ratings from plastic surgeons and 320 ratings from other specialists). For all analyses, the level of rejection adopted for the null hypothesis was 5% (p-value <0.05). RESULTS: Significant differences were observed between the two groups. On average, medical professionals who specialized in plastic surgery always obtained higher scores than other physicians. However, no significant differences were found in the assessment of the aesthetic outcome of breast reconstruction according to the sex of the rating medical professional for any of the assessments considered in this study. A strong positive linear correlation between the time since training in the medical specialty of plastic surgery (r=0.750, p=0.001) and the mean aesthetic outcome score was observed in this study. CONCLUSION: Plastic surgeons assessed the aesthetic results of breast reconstruction more positively than nonplastic physicians.

Application of acellular bovine pericardium patch in implant based immediate breast reconstruction / 中华外科杂志

Objective: To examine the clinical effect of acellular bovine pericardium patch in implant based immediate breast reconstruction. Methods: The clinicopathological information of 141 breast cancer patients, who admitted to Department of Breast Reconstruction and Oncoplastic Surgery, Tianjin Medical University Cancer Hospital, underwent immediate mammoplasty with implants combined with acellular bovine pericardium patches were analyzed from June 2016 to October 2019. All patients were female, with the age of (38.8±8.5) years (range: 13 to 60 years). The body mass index was (21.9±2.5) kg/m2 (range: 16.0 to 32.3 kg/m2). There were 39 cases of duct carcinoma in situ, 46 cases of stage Ⅰ, 40 cases of stage Ⅱ and 16 cases of stage Ⅲ. All patients received nipple-areola-sparing mastectomy or skin-sparing mastectomy with sentinel lymph node biopsy or axillary lymph node dissection, and prosthesis implantation with sub-pectoralis combined with breast patch. The correlation of clinicopathological characters and complications was assessed by t test, χ2 test, Fisher's exact probability method and Logistic regression. Pre-and post-operative aesthetic, quality of life scores were recorded. Results: The operation time (M(IQR)) was 3.6(1.5) hours (range: 3.0 to 6.5 hours). The early postoperative complication rate was 22.0% (31/141), prosthesis removal was the main postoperative complication, accounting for 64.5% (20/31) of the total complications, of which 15 cases occurred in the first 30 patients. The follow-up time was 28(8) months (range: 20 to 53 months), The most frequent long-term complications were capsular contracture and implant displacement, with the incidence of 11.2% (14/125) and 10.4% (13/125), respectively. Multivariate analysis showed that prosthesis volume ≥300 ml (OR=8.173, 95%CI: 1.302 to 51.315, P=0.021) and peri-areolar incision (OR=7.809, 95%CI: 2.162 to 28.211, P<0.01) were independent relative factors for the occurrence of short-term postoperative local complications. After 2 years of operation, the score of breast appearance satisfaction was 71.7±15.5, postoperative effect satisfaction was 90.4±9.5, psychological satisfaction was 90.7±17.1, sexual satisfaction was 70.1±25.1. The immediate postoperative satisfaction rate at discharge was 95.4% (134/141), and 17.6% (22/125) of patients had the intention to received revision surgery. Conclusions: Prosthesis volume ≥300 ml and peri-areolar incision were independent realtive factors for short-term local complications after bovine pericardium patch combined with prosthesis implantation in the immediate breast reconstruction. After completing the learning curve, the postoperative complications of the procedure could be decreased.

Surgical management of nipple areola complex in central breast cancer / 中华肿瘤杂志

Objective: To explore the surgical strategy of nipple areola complex (NAC) management in central breast cancer. Methods: A retrospective analysis was conducted on 164 cases of central breast cancer who underwent surgery treatment from December 2017 to December 2020 in the Breast Center of Beijing Tongren Hospital, Capital Medical University. Prior to the surgery, the tumor-nipple distance (TND) and the maximum diameter of the tumor were measured by magnetic resonance imaging (MRI). The presence of nipple invagination, nipple discharge, and nipple ulceration (including nipple Paget's disease) were recorded accordingly. NAC was preserved in patients with TND≥0.5 cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative intraoperative frozen pathological margin. All patients with signs of NAC involvement, TND<0.5 cm or positive NAC basal resection margin confirmed by intraoperative frozen pathology underwent NAC removal. χ(2) test or Fisher exact test was used to analyze the influencing factors. Results: Of the 164 cases of central breast cancer, 73 cases underwent breast-conserving surgery, 43 cases underwent nipple-areola complex sparing mastectomy (NSM), 34 cases underwent total mastectomy, and the remaining 14 cases underwent skin sparing mastectomy (SSM). Among the 58 cases of NAC resection (including 34 cases of total mastectomy, 14 cases of SSM, and 10 cases of breast-conserving surgery), 25 cases were confirmed tumor involving NAC (total mastectomy in 12 cases, SSM in 9 cases, and breast-conserving surgery in 4 cases). The related factors of NAC involvement included TND (P=0.040) and nipple invagination (P=0.031). There were no correlations between tumor size (P=0.519), lymph node metastasis (P=0.847), bloody nipple discharge (P=0.742) and NAC involvement. During the follow-up period of 12 to 48 months, there was 1 case of local recurrence and 3 cases of distant metastasis. Conclusions: For central breast cancer, data suggest that patients with TND≥0.5cm, no signs of NAC invasion (nipple invagination, nipple ulceration) and negative NAC margin in intraoperative frozen pathology should be treated with NAC preservation surgery, whereas for those with TND<0.5 cm or accompanied by signs of NAC invasion, NAC should be removed. In addition, nipple reconstruction can be selected to further improve the postoperative appearance of patients with central breast cancer.

Study on Automatic Plan Method for Radiotherapy after Breast-conserving Surgery Based on TiGRT System / 中国医疗器械杂志

To study an automatic plan(AP) method for radiotherapy after breast-conserving surgery based on TiGRT system and and compare with manual plan (MP). The dosimetry parameters of 10 patients and the evaluation of scoring table were analyzed, it was found that the targets dose of AP were better than that of MP, but there was no statistical difference except for CI, The V5, V20 and V30 of affected lungs and whole lungs in AP were lower than all that in MP, the Dmean of hearts was slightly higher than that of MP, but the difference was not statistically significant, the MU of AP was increase by 16.1% compared with MP, the score of AP evaluation was increase by 6.1% compared with MP. So the AP could be programmed and automated while ensuring the quality of the plan, and can be used to design the plans for radiotherapy after breast-conserving surgery.

Factors influencing decisions on contralateral symmetrisation procedure among patients with breast cancer

INTRODUCTION@#Oncoplastic breast-conserving surgery (OBCS) can cause breast asymmetry. Although contralateral breast surgery to achieve symmetry was offered to these patients, the uptake of symmetrisation was variable. We aimed to determine the factors that deter patients with breast cancer undergoing OBCS from opting for symmetrisation.@*METHODS@#All patients with breast cancer who underwent OBCS of displacement type with no symmetrisation were prospectively surveyed to explore the social, economic, psychological and physical reasons against symmetrisation.@*RESULTS@#A total of 28 patients participated in a survey administered at a mean 21.6 (range 2-47) months after OBCS. A combination of factors, such as worry and desire to treat breast cancer first (67.9%), not being overly concerned about breast cosmesis (57.1%) and fear of pain from additional operation (28.6%), deterred patients from immediate symmetrisation. Worry and desire to treat breast cancer first was the most important single factor for 50% of the patients. Reasons for no delayed symmetrisation included not being overly concerned about breast cosmesis (70.4%), fear of breast cancer recurrence (48.1%) and being happy with current breast cosmesis (33.3%), with the former two reasons equally cited as the single most important deterrent by 30% of patients each.@*CONCLUSION@#A combination of factors may deter patients from symmetrisation. The most significant factors deterring OBCS among patients were worry and desire to treat breast cancer first for immediate symmetrisation, and not being overly concerned about breast cosmesis and fear of breast cancer recurrence for delayed symmetrisation. Reassuring these patients may increase their uptake of symmetrisation, thereby improving patient cosmesis and satisfaction.

Exposed Implant after Immediate Breast Reconstruction - Presentation and Analysis of a Clinical Management Protocol / Exposição de prótese após reconstrução imediata da mama: apresentação e análise de protocolo clínico

Abstract Objective Infection and exposure of the implant are some of the most common and concerning complications after implant-based breast reconstruction. Currently, there is no consensus on the management of these complications. The aim of the present study was to review our cases and to present a clinical protocol. Methods We conducted a retrospective review of consecutive patients submitted to implant-based breast reconstruction between 2014 and 2016. All patients were managed according to a specific and structured protocol. Results Implant exposure occurred in 33 out of 277 (11.9%) implant-based reconstructions. Among these, two patients had history of radiotherapy and had their implant removed; Delayed reconstruction with a myocutaneous flap was performed in both cases. Signs of severe local infection were observed in 12 patients, and another 5 presented with extensive tissue necrosis, and they were all submitted to implant removal; of them, 8 underwent reconstruction with a tissue expander, and 2, with a myocutaneous flap. The remaining 14 patients had no signs of severe infection, previous irradiation or extensive tissue necrosis, and were submitted to primary suture as an attempt to salvage the implant. Of these, 8 cases (57.1%) managed to keep the Conclusion Our clinical protocol is based on three key points: history of radiotherapy, severe infection, and extensive tissue necrosis. It is a practical and potentially-reproducible method of managing one of the most common complications of implant-based breast reconstruction.

Resumo Objectivo Infecção e exposição da prótese são algumas das complicações mais comuns e preocupantes após reconstrução da mama com implantes. Atualmente, ainda não há consenso quanto ao manejo destas complicações. O objetivo deste estudo foi o de revisar os casos da nossa instituição e apresentar um protocolo clínico. Métodos Realizou-se uma revisão retrospectiva de todos os casos consecutivos submetidos a reconstrução mamária imediata com prótese entre 2014 e 2016. Todos os casos foram conduzidos de acordo com um protocolo específico e estruturado. Resultados A exposição do implante ocorreu em 33 de 227 reconstruções (11,9%). Dentre estas, duas pacientes tinham histórico de radioterapia, e foram submetidas a remoção da prótese e posterior reconstrução com retalho miocutâneo. Sinais de infecção local grave foram observados em 12 pacientes, e, em 5, necrose extensa de tecido, e todas foram submetidas a remoção dos implantes; destas, 8 foram recons truídas com expansor, e 2, com retalho miocutâneo. As 14 pacientes remanecentes não haviam sido submetidas previamente à radioterapia, não tinham sinais de infecção, nem necrose extensa; portanto, foram submetidas a sutura primária em uma tentativa de salvar a prótese. Dessas, 8 pacientes (57,1%) conseguiram manter os implantes originais. Conclusão Nosso protocolo clínico é baseado em três pontos principais: histórico de radioterapia, infecção grave, e necrose extensa de tecido. Ele constitui um método prático e potencialmente reprodutível de manejo de uma das complicações mais comuns da reconstrução mamária com implantes.

ABSTRACT Introduction: in the recovery period from general anesthesia the used drugs should be metabolized and the physiological alterations restored. Acupuncture is a treatment method that has been studied in the perioperative period with different aims; nevertheless its effect on the recovery from general anesthesia is less well known. Objective: to describe the acupuncture stimulation effect on the recovery from general balanced anesthesia in patients who underwent a breast nodule surgery. Materials and methods: a prospective, observational study was performed in 60 patients who underwent a surgery of breast nodule with balanced endotracheal general anesthesia, from January 2014 to January 2016, at the Provincial Teaching Hospital "Jose Ramon Lopez Tabrane" of Matanzas. Two groups were formed: group I included patients to whom acupuncture needles were placed in R1, Du 26 and P9 acupoints after surgery, and Group II patients to whom acupuncture was not performed. The acupuncture effect on anesthetic recovery was assessed using the Aldrete Scale. Two groups were formed: group I, whose members at the end of the surgery were placed acupuncture needles to in the points R1, Du26 and P9; and group II, whose members did not receive acupuncture. The effect of acupuncture on anesthetic recovery was measured through the Aldrete Scale. Results: the highest incidence age was 40 to 49 years. The physical condition of the patients, according to the American Society of Anesthesiology, was I. An anesthetic time of 61 to 90 minutes prevailed. More than 75% of the women had an anesthetic recovery time between 31 and 60 minutes. There were two minor complications attributable to acupuncture. Conclusions: acupuncture application shortened the anesthetic recovery time in the studied patients (AU).

Publications, by different surgical specialties, on patient-reported outcomes of oncoplastic surgery

Summary OBJECTIVE: This study aimed to compare the publications authored by plastic surgeons with those from other specialties' surgeons on patient-reported outcomes of oncoplastic surgery. METHODS: A review was carried out on the Medline database, emcompassing five years (2015-2020). Studies about partial breast reconstruction after conservative treatment, immediate or delayed, by any technique, which presented patient-reported outcomes, were included. RESULTS: We found 292 articles, from which 142 met the eligibility criteria. Publications were stratified into groups 1 (plastic surgeons) and 2 (other surgical specialties), and also into groups A (only plastic surgeons), B (only other specialties) and C (both), and compared statistically. Most publications (60.6%) were attributed to specialties other than plastic surgery. Nineteen percent had only plastic surgeons as authors, 50% only other specialties' surgeons, and 31% had both. There was no difference between groups regarding the impact factor of the journals in any of the stratifications, and the majority was published in journals with impact factor ≤2. CONCLUSION: In the last years, surgeons from specialties other than plastic surgery published more about the results of the oncoplastic surgery reported by the patients. There was no statistical difference between the groups regarding the impact factor of the journals.

Potential impact of the z0011 trial on the omission of axillary dissection: a retrospective cohort study / Potencial impacto do estudo Z0011 na omissão da adenectomia axilar: Estudo de coorte retrospectiva

Abstract Objective To evaluate the number of patients with early-stage breast cancer who could benefit from the omission of axillary surgery following the application of the Alliance for Clinical Trials in Oncology (ACOSOG) Z0011 trial criteria. Methods A retrospective cohort study conducted in the Hospital da Mulher da Universidade Estadual de Campinas. The study population included 384 women diagnosed with early-stage invasive breast cancer, clinically negative axilla, treated with breast-conserving surgery and sentinel lymph node biopsy, radiation therapy, chemotherapy and/or endocrine therapy, from January 2005 to December 2010. The ACOSOG Z0011 trial criteria were applied to this population and a statistical analysis was performed to make a comparison between populations. Results A total of 384 patients underwent breast-conserving surgery and sentinel lymph node biopsy. Of the total number of patients, 86 women underwent axillary lymph node dissection for metastatic sentinel lymph nodes (SNLs). One patient underwent axillary node dissection due to a suspicious SLN intraoperatively, thus, she was excluded fromthe study. Among these patients, 82/86 (95.3%) had one to two involved sentinel lymph nodes andmet the criteria for the ACOSOG Z0011 trial with the omission of axillary lymph node dissection. Among the 82 eligible women, there were only 13 cases (15.9%) of lymphovascular invasion and 62 cases (75.6%) of tumors measuring up to 2 cm in diameter (T1). Conclusion The ACOSOG Z0011 trial criteria can be applied to a select group of SLNpositive patients, reducing the costs and morbidities of breast cancer surgery.

Resumo Objetivo Avaliar o número de pacientes com câncer de mama em estágio inicial que se beneficiariam da omissão da linfadenectomia axilar segundo o protocolo Z0011 da Alliance for Clinical Trials in Oncology (ACOSOG). Métodos Estudo de coorte retrospectiva conduzido no Hospital da Mulher da Universidade Estadual de Campinas. Foram incluídas mulheres diagnosticadas com carcinoma invasivo de mama em estágio inicial, com axila clinicamente negativa, tratadas com cirurgia conservadora e biópsia do linfonodo sentinela, radioterapia, quimioterapia e/ou hormonioterapia, de janeiro de 2005 a dezembro de 2010. Os critérios do estudo da ACOSOG Z0011 foram aplicados a essas mulheres e foi realizada uma análise estatística que comparou ambas as populações dos estudos. Resultados Foram estudadas 384 mulheres submetidas a cirurgia conservadora de mama e biópsia do linfonodo sentinela. Entre elas, 86 mulheres foram submetidas a linfadenectomia axilar por metástase presente no linfonodo sentinela. Uma paciente foi submetida a linfadenectomia axilar por ter um linfonodo palpável suspeito no intraoperatório, não incluída no estudo. Entre essas 86 pacientes, 82 (95,3%) tiveram de 1 a 2 linfonodos sentinela comprometidos e seriam elegíveis para omissão da linfadenectomia axilar pelos critérios do ACOSOG Z0011. Entre as 82 pacientes elegíveis, apenas 13 (15,9%) delas apresentaram tumores com invasão angiolinfática, e 62 (75,6%) dos tumores mediram até 2 cm (T1). Conclusão Os critérios do estudo ACOZOG Z0011 podem ser aplicados a um seleto grupo de pacientes com linfonodo sentinela positivo reduzindo os custos e a morbidade cirúrgica do tratamento do câncer de mama.
