Radical Mastectomy For Breast Cancer Research Articles

Clinical Value of Total Intravenous Anesthesia with Sufentanil and Propofol in Radical Mastectomy.

Objective To investigate the clinical value of sufentanil combined with propofol for total intravenous anesthesia (TIVA) in radical mastectomy. Methods The data of 120 patients undergoing radical mastectomy of breast cancer in our hospital from February 2020 to February 2021 were retrospectively analyzed, and they were randomly assigned to the experimental group (EXG) (n = 60) and the control group (COG) (n = 60). The anesthesia maintenance scheme was 0.01–0.03 μg/(kg·min) of sufentanil + 80–100 μg/(kg·min) of propofol in EXG and 3 μg/(kg·h) of fentanyl + 80–100 μg/(kg·min) of propofol in COG. The hemodynamic indices, stress indexes, postoperative pain scores, and incidence of adverse reactions were compared between EXG and COG. Results The heart rates (HR) and mean arterial pressure (MAP) after tracheal intubation (T2) and at separation of deep tissues (T3), tracheal extubation (T4), and the end of surgery (T5) were markedly lower in EXG than in COG (P < 0.001). The stress indexes and postoperative pain scores at 1 h (T6), 6 h (T7), and 12 h (T8) after surgery were lower in EXG than in COG (P < 0.001). The incidence of dizziness, headache, pruritus, and emergence agitation in EXG was lower compared with that in COG (P < 0.05). Conclusion Sufentanil combined with propofol for TIVA can stabilize intraoperative hemodynamic indices of patients undergoing radical mastectomy, alleviate perioperative stress response, and reduce pain perception. Therefore, this anesthesia method is safe and merits clinical promotion.

Full versus half suction drainage after modified radical mastectomy for breast cancer

Background: Suction drains are routinely used after modified radical mastectomy and are an important factor contributing to increased hospital stay as the patients are often discharged only after their removal. Amongst various factors that influence the amount of postoperative drainage, the negative suction pressure applied to the drain has been reported to be of great significance. While a high negative suction pressure is expected to drain the collection and reduce the dead space promptly, it may also prevent the leaking lymphatics from closing and lead to increased drainage from the wound. Against this background a prospective randomized clinical study was conducted to compare the amount and duration of drainage between a half negative suction and full vacuum suction drainage in patients following modified radical mastectomy. The associated postoperative morbidity was also compared between the two groups. Methods: 40 FNAC (fine needle aspiration cytology) proven cases of locally advanced breast cancer were randomized. (Using randomly ordered sealed envelops, which were opened immediately before the closure of the wound) in to 20 patients with full vacuum suction (pressure = 700 g/m2) and 35 cases in to half vacuum suction drainage (pressure = 350 g/m2) groups.

Analgesia and stress attenuation of ultrasound-guided modified pectoral nerve block type-II with different volumes of 0.3% ropivacaine in patients undergoing modified radical mastectomy for breast cancer: A prospective parallel randomized double-blind controlled clinical trial.

A previous randomized clinical trial concluded that an optimal concentration of 0.3% ropivacaine could provide satisfactory analgesia for breast cancer patients undergoing modified radical mastectomy. We wondered if a smaller volume (30 ml vs. 40 ml) of 0.3% ropivacaine could still provide adequate analgesia in an ultrasound-guided PECS II block in modified radical mastectomy. We performed a prospective parallel randomized double-blind controlled clinical trial. Eligible patients were assigned to either the P30 or P40 group (30 or 40 ml of 0.3% ropivacaine, respectively). The skin area of hypoesthesia, anaesthetic plane determined with ultrasound, pain visual analogue scale (VAS), anaesthetic dosages, and complications were recorded. Serum levels of interleukin-1β and interleukin-6 were measured postoperatively. A total of 40 patients completed the trials, with 20 patients in each group. Although the skin area of hypoesthesia and the anaesthetic planes were significantly larger in the P40 group compared with the P30 group (p < 0.05), the VAS, analgesic and opioid doses, serum cytokine levels, anaesthetic toxicity, and complications had no significant differences between the two groups. Compared with 40 ml, 30 ml of 0.3% ropivacaine could provide adequate analgesia and reduce surgical stress in patients undergoing modified radical mastectomy for breast cancer.

Application of Fluorescence Dye in Combination with Methylene Blue for Axillary Reverse Mapping in Patients with Modified Radical Mastectomy for Breast Cancer.

Background Axillary reverse mapping (ARM) is a novel intraoperative technique developed in recent years. This study was aimed at determining the effect of combined use of fluorescence dye and methylene blue, as well as its feasibility of ARM in patients with breast cancers who undergo modified radical mastectomy. Method From January 2016 to June 2017, 46 patients with primary breast cancer at stage I-IV (Tis-T3, N0-N3, and M0) who received modified radical mastectomy were enrolled in this study. The exclusion criteria included preoperative radiotherapy/chemotherapy or bilateral disease. Patients were divided into 2 groups: methylene blue group (22 patients, 47.8%) and methylene blue+indocyanine green (ICG) group (24 patients, 52.2%). ARM was performed before surgery. Results The overall visualization rate of ARM nodes was 80.4% (37/46). The visualization rate was significantly increased in methylene blue+ICG group (91.67%, 22/24) than that in methylene blue group (63.64%, 14/22) (P = 0.032). There was a statistical difference of visualization rate between clinical groups of N0-N1 and N3-N4 (t = 2.431, P = 0.19 < 0.05). Although there was no significant difference found in the total drainage volume and arm perimeter of patients between the two groups (P > 0.05), the harden diameter of the injection site in methylene blue+ICG group was significantly longer than that in methylene blue group (P < 0.05). Among the 44 patients with different molecular profiling of breast cancer, there was no significant difference of visualization rate of ARM nodes in luminal A group (100%,5/5), luminal B group (75.0%, 18/24, P = 0.21), HER2 group (75.0%, 6/8, P = 0.22), and basal-like group (85.7%, 6/7, P = 0.37). Conclusions ARM using methylene blue+ICG presented greater identification rate than that with methylene blue alone, especially in patients with more invasive breast cancer. Our finding offers support for the improvement of ARM in future breast cancer management.

Value Analysis of Neoadjuvant Radiotherapy for Breast Cancer after Modified Radical Mastectomy Based on Data Mining.

Over the last two generations, there has been a surge of interest in nonmutilating treatment for women with early breast cancer. Neoadjuvant radiation therapy, which is progressively being provided to breast cancer patients, could be used to decrease tumor burden while also providing an ability to examine treatment response. This paper aims to explore the effects of the initiation time of radiotherapy after modified adjuvant radical mastectomy on the prognosis of breast cancer. The EMR data can be used to mine hidden rules, which are of great significance for treatment and prognosis analysis. In collaboration with breast cancer, the appropriate prediction model and visualization method are selected and a visual analysis system for breast cancer group and treatment plan based on electronic medical record is constructed. Patients with multiple dimensions are reduced and clustered to form patient groups. The differences of characteristics among patient groups are intuitively displayed by using Nightingale diagram, word cloud, and time axis visualization methods. The support vector machine (SVM) model is used to predict the treatment scheme. The radiotherapy time after modified radical surgery in the two groups was within 15 weeks (observation group) and 15 weeks (routine group), respectively. The incidence of complications, local recurrence rate, progression-free survival, and quality of life scores of patients in the routine group and observation group were compared. The total incidence of complications differed significantly between the observation and routine groups. The physical function, material function, psychological function, and social function of the observation group were significantly higher than the routine group (P < 0.05). Radiotherapy within 15 weeks after modified radical mastectomy for breast cancer can not only reduce the local recurrence rate but also prolong the progression-free survival of patients, and the incidence of complications will not increase, which will greatly help improve the quality of life of patients.

Impact of Ultrasound-Guided Deep Serratus Anterior Plane Block Combined With Dexmedetomidine as an Adjuvant to Ropivacaine Inpatient Quality of Recovery Scores Undergoing Modified Radical Mastectomy: A Randomized Controlled Trial.

BackgroundBreast cancer has overtaken lung cancer as the most commonly diagnosed malignancy and is the leading cause of cancer-related death in women. Surgery is the only possible cure for breast cancer, and the incidence of acute postoperative pain (APP) is high in breast surgery. Previous reports suggested that ultrasound-guided deep serratus anterior plane block (dSAPB) provided effective blockade to relieve pain after modified radical mastectomy for breast cancer. In fact, despite the long-acting local anesthetic agents used, the patient’s pain cannot completely be eliminated due to the short duration of anesthesia. Dexmedetomidine as an adjunct to local anesthetics can prolong peripheral nerve block duration. However, no study has investigated the role of dSAPB with dexmedetomidine in the quality of recovery scores undergoing modified radical mastectomy. Thus, this study was conducted aiming at this aspect.Material and MethodsThis single-center, double-blind, randomized clinical trial was conducted at Bethune International Peace Hospital. A total of 88 participants of elective modified radical mastectomy were enrolled from May and November 2021. Ultrasound-guided dSAPB combined with 30 ml of 0.375% ropivacaine or 30 ml of 0.375% ropivacaine with dexmedetomidine (1 μg/kg) was administrated before anesthesia at the fourth to fifth ribs of the axillary midline. The primary outcome was quality of recovery, measured 24 h postoperatively using the QoR-15. Secondary outcomes were the Visual Analogue Scale (VAS) scores at rest and movement at 1, 6, 12, 24, and 48 h after surgery, 48 h sufentanil consumption postoperatively, the incidence of postoperative nausea and vomiting (PONV), length of post-anesthesia care unit (PACU) stay, dizziness, delirium, SAPB-related adverse events, and patient’s satisfaction with pain management.ResultsAmong the 88 participants, 8 did not meet the inclusion criteria; the other 80 were randomized to receive dSAPB combined with ropivacaine (Group R, N=40) and dSAPB combined with ropivacaine plus DEX (Group RD, N=40), of which a total of 7 (4 in Group R and 3 in Group RD) were excluded due to protocol deviation. Eventually,73 participants (36 in Group R and 37 in Group RD) were included for final analysis, with age (SD, years, 54.08[6.28] vs. 54.62[7.44], p=0.740), body mass index (BMI) (SD, 27.96[1.67] vs. 27.57[2.38], p=0.428), and median preoperative global QoR-15 score (interquartile range (IQR), 127[123.25–131] vs. 126[121–130], p=0.662). The median postoperative global QoR-15 score (IQR, 107[103–112] vs. 109.5[107–114], p=0.016), VAS score at rest at 12th hour (IQR, 1[1–2] vs. 1[1–2], p=0.033), VAS score in movement at 12th hour (IQR, 2[1–3] vs. 2[1–3], p=0.014) and at 24th hour (IQR, 3[2–3] vs. 3[2–3], p=0.040), and median sufentanil rescues consumption (IQR, 14[12–17 vs. 14[12–15], p=0.022] of Group RD were significantly lower than those of the Group R. Patient satisfaction score (SD, 8.28[0.70] vs. 8.62[0.59], p=0.024) of Group RD were significantly higher than those of the Group R.ConclusionThe ultrasound-guided dSAPB combined with dexmedetomidine plus ropivacaine may improve the QoR-15 in patients undergoing modified radical mastectomy and indicates that it may be a useful intervention to aid recovery following breast cancer surgery. Furthermore, participants in the ropivacaine with DEX group met the superior pain relief in the early postoperative period, reduced postoperative cumulative opioid consumption, increased patient satisfaction, and no increase in the incidence of complications.

Abstract No. : ABS1591: Effect of erector spinae block and PECS block on quality of recovery and analgesia after modified radical mastectomy

Background and Aims:Breast cancer is the most common malignancy in women ; modified radical mastectomy is one of the standard treatments.This study compared the effect of erector spinae block and pectoralis(PECS) block on quality of recovery and analgesia after modified radical mastectomyMethods:The present randomised controlled double-blind study was conducted on 90 patients undergoing unilateral modified radical mastectomy for breast cancer. The patients were randomised into group-I (PECS block 20ml 0.25% bupivacaine, n=30), group-II (erector spinae block 20ml 0.25% bupivacaine, n=30) and group-III (control group, n=30). Along with clinical anddemographical data, the requirement of the first dose of rescue analgesia, total rescue analgesic consumption, visual analogue scale(VAS) scores and Quality of Recovery(QoR) -40 scoreswere compared. Anaesthesia and surgical interventions were done as per standard protocol.Results:Mean first rescue analgesic requirement was significantly delayed in group-I followed by group-II compared to controls . Mean total rescue analgesic consumption was much lower in group-I and group-II as compared to group-III and the difference was statistically significant (p<0.0001)(figure 1). Mean VAS scores were also much lower in group-I followed by group-II as compared to group-III at different follow-ups, and difference was statistically significant. The global QoR-40 at 24 hours showed significantly better outcomes in group-1(table 1)Figure 1Global QoR-40 between the groupsTable 1Postoperative tramadol requirementAnalgesic requirementGroup B (n=30)Group C (n=30) P Time for 1st need of tramadol (h)8.10±1.480.7±0.38<0.001Total tramadol consumption (mg)68±48.55210±52.65<0.0001Total numberof patients requiring tramadol (%) 24 h10 (33.33%)30 (100%)<0.0001Table 1Quality of Recovery(QoR) -40 scores between the groupsGlobal QoR-40 (0-200)Group I (n=30)Group-II (n=30)Group-III (n=30) P Pre-operative186.63±7.78185.53±6.73186.34±7.56P=0.8360At 24 h183.64±6.36179.68±6.38171.37±6.88P<0.001* P t=1.63, P=0.1086t=3.455, P=0.0010*t=8.021, P<0.001*Conclusion:Both PECS and ESP block can be used efficaciously for providing analgesia in modified radical mastectomy for breast cancer.

Incidence of Primary Complications Afterwards Modified Radical Mastectomy in Breast Cancer

The cancer of breast is the 2nd leading source of cancer death in females. A modified radical mastectomy encompassed the combines removal of the axillary lymph nodes with all breast tissue removal from the affected breast. The most common complication of surgery is formation of seroma. Inadequate data is accessible on this topic. This analysis therefore provides valued information on this problem associated with infection of wound. Objective: To govern the initial complications after radical modified mastectomy in women with cancer of breast. Study Design: A descriptive case study. Place and Duration: In the Surgical department of Muhammad Teaching Hospital, Peshawar for the duration of one-year from November 2020 to October 2021. Methods: This descriptive case study was conducted at the surgical department of Muhammad Teaching Hospital, Peshawar for the duration of one-year from November 2020 to October 2021. The estimated sample size had an incidence of 18%, margin of error = 10% and CI = 95% of the sample size required is 62 patients. The sampling method used was non-probability purposive. Patients who met the selection criteria underwent a modified radical mastectomy with the prior conversant written consent. The patients were discharged home on the second day of surgery and were monitored weekly for the first 6 weeks at the clinic for primary complications such as seroma formation and wound infection. All related demographic data such as clinical information and age such breast cancer staging with possible complications were recorded at the culmination of 6-weeks. Data were entered into SPSS software version 21 and analyzed. Results: The study included 62 females with a modified radical mastectomy for breast cancer who fully met the criteria of inclusion. 46.10± 13.02 years was the patients mean age with 20-75 years age range. The mean postoperative day of infection in wound was 4.60± 1.9 days and the mean postoperative day for seroma was 9.21± 3.98 days. Stage II breast cancer was diagnosed in 44 patients (70.9%) and stage I breast cancer in 18 patients (29.1%). Wound infection was observed in 5 patients (8.1%), while 16 patients (25.8%) experienced complications related to seroma formation. Conclusion: This study showed that complications such as infection in the wound are significantly lower, but the incidence of seroma is consistent with nationwide studies that justify novel interferences to reduce the rate of these complications. Keywords: Modified radical mastectomy, Seroma, Wound infection.

Functional Network Connectivity Reveals the Brain Functional Alterations in Breast Cancer Survivors.

Different neurological and psychiatric disorders such as vertebrobasilar insufficiency, chronic pain syndrome, anxiety, and depression are observed in more than 90% of patients after treatment for breast cancer and may cause alterations in the functional connectivity of the default mode network. The purpose of the present study is to assess changes in the functional connectivity of the default mode network in patients after breast cancer treatment using resting state functional magnetic resonance imaging (rs-fMRI). Rs-fMRI was performed using a 3.0T MR-scanner on patients (N = 46, women) with neurological disorders (chronic pain, dizziness, headaches, and/or tinnitus) in the late postoperative period (>12 months) after Patey radical mastectomy for breast cancer. According to the intergroup statistical analysis, there were differences in the functional connectivity of the default mode network in all 46 patients after breast cancer treatment compared to the control group (p < 0.01). The use of rs-fMRI in in breast cancer survivors allowed us to identify changes in the functional connectivity in the brain caused by neurological disorders, which correlated with a decreased quality of life in these patients. The results indicate the necessity to improve treatment and rehabilitation methods in this group of patients.

Functional MRI in the assessment of changes in the brain connectome in patients with post-mastectomy syndrome

Introduction. In the postoperative period after total mastectomy, patients develop postmastectomy syndrome, including upper limb lymphedema and a number of neuropsychiatric disorders that affect the functional state of the brain and reduce the quality of life.Purpose of the study. Evaluation of changes in functional connectivity of the default mode network in patients with post-mastectomy syndrome using resting state functional MRI.Materials and methods. Resting state functional MRI was performed to 46 patients aged 30 to 50 years with neurological disorders in the late postoperative period (&gt;6 months) after radical mastectomy for breast cancer, as well as 20 healthy women from the control group.Results. According to the intergroup statistical analysis, there were differences in functional connectivity of the default mode network in all 46 patients with post-mastectomy syndrome, compared to the control group (p&lt;0,01).Conclusion. The revealed changes in the functional connectivity of the default mode network of the brain indicate the functional reorganization of the brain connectome in patients with neurological manifestations of post-mastectomy syndrome.

Role of Autologous Fibrin Glue (AFG) to Reduce Drainage Volume After Modified Radical Mastectomy for Breast Cancer

Background: Seroma is arguably the most significant complication that can happen after mastectomy. Although seroma is not a life-threatening complication, this condition can lead to severe morbidities. This situation can cause prolonged hospital stays and delayed adjuvant therapy. In this regard, autologous fibrin glue is a hemostatic agent that can accelerate fibrin formation, stop vascular oozing, and decrease dead space. Therefore, this research was performed to evaluate autologous fibrin glue function in lowering seroma volume after mastectomy and shortening the length of hospital stay.Methods: This randomized control trial research was designed to compare the effect of autologous fibrin glue to a control group that did not receive autologous fibrin glue. Seroma volume was calculated every 24 hours. The drains were then removed after the production of seroma less than 30 mL/24 hours.Results: We recruited 20 patients for each of the two groups who met the inclusion criteria. Age, histopathology type, breast cancer stage, number of lymph nodes, and tumor size did not significantly differ. However, patients in the fibrin glue group had significantly lower cumulative drain production. The median seroma volume in the treatment group was 9.30 mL, while the median in the control group was 20.90 mL (p &lt; 0.05).Conclusions: Autologous fibrin glue significantly decreased seroma formation and length of hospital stay.

SP8.1.1 Ultrasonic versus electrocautery dissection in modified radical mastectomy for breast cancer: A Systematic Review and Meta-analysis

Abstract Aims Electrocautery (EC) remains the dominant dissection tool in modified radical mastectomy (MRM) for breast cancer. However, ultrasonic dissection devices (UDD) have emerged as popular alternatives on the basis that their mechanism of action limits tissue damage resulting in decreased blood loss, seroma formation and post-operative drainage. A systematic review and meta-analysis was performed to compare surgical outcomes for EC versus UDD in MRM surgery. Methods MEDLINE, EMBASE, PubMed and the Cochrane Database were searched and a comprehensive systematic review and meta-analysis performed according to PRISMA guidelines, comparing EC versus UDD in MRM for breast cancer. Outcomes of interest were post-operative drainage, incidence of seroma, intra-operative blood loss and operative time. Meta-analysis was performed using a random effects model to aggregate the data. Odds ratios (OR) were used as the summary statistic for dichotomous data and mean difference (MD) for continuous data. Data heterogeneity was assessed using the I2 statistic. Results Nineteen eligible peer-reviewed studies were analysed involving 1501 patients, UDD:744 EC:757. We demonstrated that in MRM, UDD significantly reduced post-operative drainage (MD = 312.26, 95% confidence interval (CI): 102.59-521.93, p = 0.004); seroma (OR = 0.51, 95% CI: 0.39-0.68, p &amp;lt; 0.00001) and intra-operative blood loss (MD = 111.68, 95% CI: 84.56-138.8, p &amp;lt; 0.00001) with no significant difference in operative time between the two techniques (MD = 0.32 (11.3-11.94), p = 0.96. Conclusion Using UDD in MRM for breast cancer presents significant advantages in decreasing post-operative drainage, seroma and intra-operative blood loss, without lengthening operating time compared to EC. It therefore appears favourable, however further cost-effectiveness analysis would be beneficial to guide selection.

Risk factors and nursing countermeasures of postoperative pulmonary infection in patients with breast cancer: A retrospective analysis.

It is necessary to elucidate the potential risk factors of pulmonary infection to provide references for the management of breast cancer.Our study was a retrospective design, patients who underwent modified radical mastectomy for breast cancer in our department of breast surgery from January 2019 to November 2020 were included. The personal and clinical data of included patients with and without pulmonary infection were compared.A total of 234 patients with radical mastectomy were included, the incidence of pulmonary infection was 15.38% with 95%confidence interval (CI) 11.42% to 18.98%. There were significant differences in the age, body mass index, diabetes, duration of surgery, combined radiotherapy and chemotherapy, and duration of drainage between patients with and without pulmonary infections (all P < .05). Logistic regression analysis indicated that age ≥55 years (odds ratio [OR] 2.128, 95%CI 1.105–3.426), body mass index ≥ 24 kg/m2(OR 2.344, 95%CI 1.031–3.299), diabetes (OR 2.835, 95%CI 1.132–4.552), duration of surgery ≥120 minutes (OR 1.394, 95%CI 1.012–1.044), combined radiotherapy and chemotherapy (OR 3.122, 95%CI 1.124–5.273), duration of drainage ≥5 days (OR 1.851, 95%CI 1.112–2.045) might be the independent risk factors of pulmonary infection in patients after radical mastectomy(all P < .05). Pseudomonas aeruginosa and Klebsiella pneumoniae are the most commonly seen bacteria.The incidence of postoperative pulmonary infections in breast cancer patients is high, and there are many associated risk factors. The perioperative management of patients should be strengthened targeted on those risk factors in clinical practice.

A Randomized Controlled Study of Quilting with Axillary Lymphatic Ligation Versus Conventional Modified Radical Mastectomy in Patients with Breast Cancer.

Postmastectomy seroma formation is a common and notorious problem that every treating surgeon frequently faces in the management of patients with breast cancer. Several technical modifications and innovations have been proposed to either overcome or reduce its occurrence. One such method tested in this study in a randomized way was axillary lymphatic vessel ligation and quilting. A total of 120 patients undergoing modified radical mastectomy for breast cancer were randomized to undergo either conventional modified radical mastectomy (MRM) or MRM with axillary lymphatic vessel ligation using a loupe magnification and quilting. Both the groups were identical in terms of baseline characteristics. Compared to conventional MRM, experimental group was associated with statistically significant longer operative time, more blood loss, less seroma aspirations, early drain removal, shorter hospital stay, early start of adjuvant chemotherapy, and better ipsilateral shoulder function. To conclude axillary lymphatic vessel ligation and quilting, the technique needs to be incorporated into the technique of MRM and the relative contribution of each of these strategies needs to be explored further through newer studies.

Application of MET Technique after Upper Limb Dysfunction after Breast Cancer Surgery

Object: Explore the application and actual effect of MET (Muscle Energy) technology after breast cancer surgery with upper limb dysfunction. Methods: Taking 40 female breast cancer patients who underwent surgical treatment in our hospital from September 2017 to June 2019 as the research objects, all of them successfully completed modified radical mastectomy for breast cancer. According to different nursing methods, the patients were randomly divided into two groups. The experiment There were 20 cases in each group and the control group. The control group was given routine functional recovery exercise intervention after the operation, and the experimental group added MET technology to the base of the control group. One month after the operation, the functional recovery of the affected limbs of the two groups of patients was effectively assessed. The upper limb dysfunction of the two groups was compared by statistical methods, and the shoulder joint range of motion (ROM) was used for performance. Results: Through early functional recovery training and MET technology, 19 cases of ROM in the experimental group showed compliance (95%), compared with only 14 cases (70%) in the control group. The difference in upper limb dysfunction between the two groups is very obvious with statistical significance (P&lt;0.05). Conclusions: Early functional recovery training combined with muscle energy technology can promote the recovery of upper limb dysfunction after breast cancer surgery faster and better, which is conducive to the recovery of patients as soon as possible and improve the quality of life.

A randomised trial: effects of different anesthesia methods on early perioperative pain sensitivity and cellular immune function in patients undergoing radical mastectomy.

This study sought to investigate the effects of transversus thoracic muscle plane-pectoral nerves (TTP-PECS) block combined with propofol anesthesia on early perioperative pain sensitivity and cellular immune function in patients undergoing radical mastectomy. A total of 115 patients who underwent radical mastectomy for breast cancer at our hospital from January 2019 to January 2021 were selected as the study subjects. The patients were allocated to the control group (n=57) or observation group (n=58) using a random number method. The control group was given simple general anesthesia, and the observation group was given TTP-PECS block combined with propofol anesthesia. The recovery time, pain [visual analogue scoring (VAS)] scores, and incidences of adverse reactions were compared between the 2 groups. Hemodynamic indicators [i.e., heart rate (HR), mean arterial pressure (MAP)], stress indicators [i.e., blood glucose (GLU), epinephrine (E), cortisol (Cor)], and the cellular immune function ofthe2 groups before anesthesia (T0), at the end of operation (T1), 1day after operation (T2) and 3days after operation (T3) were recorded. The spontaneous respiration recovery time, time to full wakefulness and the extubation time of the observation group were shorter than those of the control group (P<0.05). The observation group had lower VAS scores than the control group at 2, 8, 12, and 24 h after operation (P<0.05). The levels of MAP, HR, GLU, E and Cor in the observation group at T1, T2, and T3 were lower than those in the control group (P<0.05). Compared to the control group, the observation group had increased cluster of differentiation (CD)3+, CD4+, and CD4+/CD8+ cells (P<0.05), but there were no significant differences in CD8+ and natural killer (NK) cells between the 2 groups (P>0.05). The incidence of adverse reactions in the observation group was lower than that in the control group (8.62% vs. 24.56%) (P<0.05). TTP-PECS block combined with propofol anesthesia can relieve pain, shorten the recovery time, stabilize the hemodynamic level, and alleviate the stress responses of patients undergoing radical mastectomy with a slight suppression of cellular immune function and high safety.

The application of personalized rehabilitation exercises in the postoperative rehabilitation of breast cancer patients.

This study sought to explore the effects of personalized rehabilitation exercises in the postoperative rehabilitation of breast cancer patients. A total of 93 breast cancer patients admitted to our hospital from January 2018 to December 2019 were taken as research subjects for this study. Based on order of admission, patients were assigned to a control group (46 cases) or an observation group (47 cases). All patients underwent a modified radical mastectomy for breast cancer. Patients in the control group received routine nursing and rehabilitation training after their operations, while those in the observation group received personalized rehabilitation exercises (for a period of 6 months) in addition to the rehabilitation training received by the control group. The immune function indicators, the incidence of upper limb-related complications, the movement of the shoulder joint, upper limb function, ability of daily living (ADL), and quality of life (QoL) was then compared between the two groups before and after the intervention. Patients in the observation group had lower incidences of upper limb edema and subcutaneous fluid than those in the control group (P<0.05). Further, following the intervention, compared to patients in the control group, patients in the observation group had higher CD4+, CD4+/CD8+ levels, lower CD8+ levels, a greater range of motion in their shoulder joints (P<0.05), lower upper limb function impairment scores [based on the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire] (P<0.05), higher ADL scores (P<0.05), and higher QoL scores (P<0.05). Personalized rehabilitation exercises reduced the postoperative upper limb complications experienced by breast cancer patients, improved their immune function, shoulder joint mobility and upper limb function, and improved their ADL and QoL.

Effect of autologous fibrin glue on seroma reduction after modified radical mastectomy for breast cancer: A randomized controlled trial

IntroductionBreast cancer stands out as the second most common cancer in the world with incidence 35.1% of all malignancies among females in Egypt. Fluid build-up after breast surgery is still the most annoying complication which leads to worse outcome. We aimed to evaluate whether autologous fibrin glue might lessen the formation of seroma following modified radical mastectomy. MethodsThis was a randomized controlled trial designed to configure the effect of autologous fibrin glue given in the study group using the drain in comparison to a control group who received the drain only; seroma volume was calculated every 24 h. For all of the cases. The drains were removed when the daily drainage was less than 30 ml for 3 consecutive days. ResultsWe recruited 30 patients to each of the two groups. Age, pathology, breast cancer stage, number of lymph nodes and tumour size did not differ significantly between groups. A comparison of the median days to drain removal showed 8 days reduction in median days to drain removal compared in the intervention group (7 days) than the control (15 days). The patients in the fibrin glue group had a significantly lower cumulative drain output volume (mean ± SD of 505,6 ± 209,3 ml) than those in the control group (1674.1 ± 1 373,8 ml). ConclusionsAutologous fibrin glue significantly decrease seroma formation post-modified radical mastectomy.
