Combined Thoracic Paravertebral Block-Interscalene Block as a Primary Anesthetic for Modified Radical Mastectomy: A Case Report.

Background: Regional anesthesia as a primary anesthetic can offer merits over general anesthesia for patients having multiple comorbidities who are at a high risk of perioperative morbidity and mortality. Thoracic paravertebral block (TPVB) and interscalene block (ISB) have been used widely to improve the quality of postoperative analgesia after breast surgery. Objective: There are limited data on the feasibility of combining TPVB-ISB as a sole anesthetic technique for extensive breast surgery with axillary lymph nodes dissection. Case presentation: In this report, the author presented a successful use of a combined TPVB and ISB as a sole anesthetic with conscious sedation in a 52-year-old patient with multiple comorbidities, including heart failure with reduced ejection fraction, who underwent modified radical mastectomy with left axillary lymph nodes dissection. Conclusion: Combining TPVB-ISB can be used as a sole anesthetic for extensive breast surgery in patients with a high risk for general anesthesia.

"Combination of Thoracic Epidural Anesthesia, Supraclavicular Brachial Plexus Block and Supraclavicular Nerve Block as Surgical Anesthesia for Modified Radical Mastectomy-A Case Series".

Sensory innervation of the breast is complex, thereby making it difficult to perform any surgical procedure with a single regional anesthesia technique. Because of the involvement of pectoral muscles and extension of the incision into the axilla, a modified radical mastectomy makes it further challenging and requires multiple techniques. We have used a new combination of regional techniques in this case series and found that it provided complete surgical anesthesia with a smaller volume of local anesthetic.

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.

WHAT IS KNOWN AND OBJECTIVE: 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. METHODS: 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-1ß and interleukin-6 were measured postoperatively. RESULTS AND DISCUSSION: 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. WHAT IS NEW AND CONCLUSION: 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.

Study on short-term cosmetic effects and quality of life after breast cancer modified radical mastectomy combined with one-stage prosthesis implantation.

Background: This study investigated the reconstruction effect of skin-preserving breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation in female patients to analyze relevant factors and observe the effect of prosthesis reconstruction on short-term breast satisfaction, psycho-social functions, and quality of life (QOL) in patients with breast cancer after the operation. Methods: Patients were divided into two groups based on the reconstruction effect (an excellent effect group and a good and general effect group). Patients' short-term cosmetic effect on the breast after breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation was prospectively followed up to analyze influencing factors. At post-operative 6 months, the breast satisfaction dimension, psycho-social dimension, upper limb breast health dimension, and surgical satisfaction dimension in the prosthesis reconstruction module in the BREAST-Q scale were used for follow-up evaluation. Results: The excellent rate of prosthesis reconstruction was 91.3%. A significant correlation was observed among the reconstruction effect, implant volume, and number of children born by the patient (P < 0.05). The correlation with age, BMI (body mass index), operation time, nipple and areola retention, operation method, and incision was not statistically significant (P > 0.05). At post-operative 6 months, the Breast-Q score was significantly different in the overall breast satisfaction dimension and outcome satisfaction dimension between the two groups (P < 0.05). Conclusion: Breast cancer modified radical mastectomy combined with one-stage breast prosthesis implantation can not only fulfill patients' physical aesthetic needs but also positively affect their psychosocial behavior to improve post-operative QOL.

Anesthetic effect of ultrasound-guided multiple-nerve blockade in modified radical mastectomy in patients with breast cancer.

INTRODUCTION: Routine anesthesia modality for modified radical mastectomy (MRM) includes general anesthesia (GA), epidural blockade-combined GA and nerve blockade-combined GA. However, GA has been associated with postoperative adverse effects such as vertigo, postoperative nausea and vomiting and requirement for postoperative analgesia, which hinders recovery and prognosis. Moreover, combined blockade of thoracic paravertebral nerves or intercostal nerves and adjuvant basic sedation for massive lumpectomy provided perfect anesthesia and reduced opioid consumption, whereas the excision coverage did not attain the target of MRM. Regional anesthesia strategies involving supplementation of analgesics in ultrasound-guided multiple nerve blocks have garnered interests of clinicians. Nevertheless, the precise effects of intercostal nerves, brachial plexus and supraclavicular nerves in MRM in patients with breast cancer remain obscure. METHODS: Eighty female patients with breast cancer scheduled for MRM were recruited in the present trial between May, 2019 and Dec., 2019 in our hospital. The patients ranged from 30 to 65 years of age and 18∼30 kg/m2 in body-mass index, with the American Society of Anesthesiologists I or II. The patients were randomized to ultrasound-guided multiple nerve blocks group and GA group. The patients in multiple nerve blocks group underwent ultrasound guided multiple intercostal nerve blocks, interscalene brachial plexus and supraclavicular nerve blocks, (local anesthesia with 0.3% ropivacaine: 5 ml for each intercostal nerve block, 8 ml for brachial plexus block, 7 mL for supraclavicular nerve block) and basic sedation and intraoperative mask oxygen inhalation. The variations of hemodynamic parameters such as mean arterial pressure, heart rate (HR) and pulse oxygen saturation were monitored. The visual analog scale scores were recorded at postoperative 0 hour, 3 hour, 6 hour, 12 hour and 24 hour in resting state. The postoperative adverse effects, including vertigo, postoperative nausea, and vomiting, pruritus, and urinary retention and so on, as well as the analgesic consumption were recorded. CONCLUSIONS: The ultrasound guided multiple intercostal nerve blocks, brachial plexus and supraclavicular nerve blocks could provide favorable anesthesia and analgesia, with noninferiority to GA and the reduced incidence of adverse effects and consumption of postoperative analgesics.

Development and validation of a nomogram to predict drainage duration in patients with breast cancer treated with modified radical mastectomy.

Appropriate drainage duration is vital for the postoperative rehabilitation of patients with breast cancer (BC) undergoing modified radical mastectomy (MRM). To provide better and individualized postoperative management for these patients, this study explored independent predictors of postoperative drainage duration in patients with BC. This was a single-center retrospective cohort study. Patients diagnosed with BC and treated with MRM from May 2016 to April 2020 were randomly divided into training (n = 729) and validation (n = 243) cohorts. Univariate and multivariate Cox analyses revealed that the body mass index, serum albumin level, hypertension, number of total dissected axillary lymph nodes, and ratio of positive axillary lymph nodes were independent predictors of postoperative drainage duration in the training cohort. Based on independent predictors, a nomogram was constructed to predict the median postoperative drainage duration and the probability of retaining the suction drain during this period. This nomogram had good concordance and discrimination both in the training and validation cohorts and could effectively predict the probability of retaining the suction drain during drainage, thus assisting clinicians in predicting postoperative drainage duration and providing individualized postoperative management for patients with BC.

Concomitant fulvestrant with reirradiation for unresectable locoregional recurrent estrogen receptor positive (ER+) breast cancer: A case report and narrative review.

RATIONALE: Locoregional recurrence of breast cancer is a challenging issue for clinicians. Treatment options for unresectable recurrent estrogen receptor positive (ER+) breast cancer in previously irradiated area are limited. Some studies showed concomitant fulvestrant with radiation therapy might increase radiosensitivity compared with radiation alone in vitro, no in vivo reports yet. PATIENT CONCERN: Here, we present a case report and make a narrative review of concomitant fulvestrant with radiation therapy for unresectable locoregional recurrent ER+ breast cancer. The patient was treated with modified radical mastectomy in 2015, adjuvant chemotherapy, radiotherapy, followed by exemestane until November 2018, relapsed in internal mammary lymph nodes with sternum involved. DIAGNOSIS: The final diagnosis was breast cancer internal mammary lymph nodes metastasis with sternum involved. INTERVENTIONS: After diagnosis was made, concurrent fulvestrant with reirradiation as a palliative treatment were proposed under multiple disciplinary team. OUTCOMES: There was a good clinical response, enabling curative chance with radiation therapy to a total dose of 60 Gy. Computed tomography scan revealed no evidence of residual tumor. LESSONS: As far as we know, this is the first report concerning concomitant fulvestrant with reirradiation for unresectable locoregional recurrent ER+ breast cancer. Since no severe adverse events were observed, this strategy could be a suitable "loco-regional rescue therapy" to further reduce tumor progression or even reach a curative effect. Studies of this treatment strategy in randomized clinical trials are warranted to further assess its safety and effectiveness.

Evaluation of Pectoral Nerve Block in Modified Radical Mastectomy: Comparison of Three Concentrations of Ropivacaine.

BACKGROUND: Pectoral nerve block type I (PECS I Block) and type II (PECS II Block) with ropivacaine are relatively new analgesic methods for breast-cancer surgery. We evaluated the safety and efficacy of different concentrations of ropivacaine given in the same volume for the PECS II Block in patients undergoing modified radical mastectomy (MRM). PATIENTS AND METHODS: One hundred and twenty women undergoing elective MRM who met inclusion criteria were divided randomly into four groups of 30: control group without PECS II Block and R0.2%, R0.3%, and R0.4% groups, who received general anesthesia plus the PECS II Block with ropivacaine at 0.2%, 0.3%, and 0.4%, respectively, in a volume of 40 mL. RESULTS: The postoperative numerical rating scale (NRS) pain score at rest and active was significantly higher in the control group than that in the three ropivacaine groups (P<0.05 for all), and the postoperative NRS score in the R0.3% group and R0.4% group at 12, 24, and 48 h postoperatively were significantly lower than that in the R0.2% group (P<0.05 for all); there was no significant difference between the R0.3% group and R0.4% group. The time when pain was first felt after MRM, the total number of complaints during 3, 6, 12, 24, and 48 h after MRM, and the total analgesic requirement (tramadol consumption) during the first 24 h postoperatively in the R0.3% group and R0.4% group were significantly lower than those in the control group and R0.2% group (P<0.05 for all); there was no significant difference between the R0.3% group and R0.4% group. CONCLUSION: A dose of 0.3% ropivacaine was the optimal concentration for a PECS II Block for patients undergoing MRM because it provided efficacious analgesia during and >48 h after MRM. Increasing the ropivacaine concentration did not improve the analgesia of the PECS II Block significantly.

Ultrasound-guided Interfascial Plane Blocks for Non-anesthesiologists in Breast Cancer Surgery: Functional Outcomes and Benefits.

AIM: Acute post-operative pain following modified radical mastectomy (MRM) in patients with breast cancer is challenging for anesthesiologists. This study aimed to prospectively compare the quality outcome of interfascial plane blocks performed with ultrasound guidance, and evaluate the consequences of sharing tasks with the breast surgeon. PATIENTS AND METHODS: The study involved 255 patients scheduled for unilateral MRM, who were divided into two groups: Pecs group: General anesthesia plus ultrasound-guided modified pectoral nerves blocks type I and II, including serratus and parasternal infiltration according to surgical requirements; and Control group: general anesthesia only. Quality was evaluated based on perioperative opioid consumption, reported pain intensity, rescue analgesic requirement, side-effects and length of hospital stay. Moreover, a breast surgeon with expertise in ultrasound-guided breast biopsy was trained to perform the blocks. The patient benefits from regional anesthesia delivered by a non-anesthesiologist were assessed. RESULTS: Significant reductions were noted in all of the following: Intraoperative opioid consumption (p<0.001), Numerating Rating Scale pain scores taken 0 and 24 h after surgery (p<0.001), post-operative analgesic administration (p<0.001), nausea and vomiting at 0, 6, and 12-h intervals (p<0.05), and hospital stay (p<0.001) were observed in the Pecs group compared with the control group. Furthermore, data obtained from patients receiving the block from the surgeon showed comparable benefits with no complications. CONCLUSION: Interfascial plane blocks may be an important alternative protocol in MRM, enhancing patient safety and cost benefits. Improvements in cross-disciplinary expertise through flexibility in the training of professionals with other backgrounds may provide effective analgesia and favorable outcomes.

Effect of breast-conserving surgery and modified radical mastectomy on operation index, symptom checklist-90 score and prognosis in patients with early breast cancer.

The present study aims to analyze the effects of breast-conserving surgery and modified radical mastectomy on operation indexes, Symptom checklist-90 scores and prognosis in patients with early breast cancer.The clinical data of 128 patients with breast cancer who were treated in our hospital from May 2015 to May 2016 were included into the analysis. These patients were divided into 2 groups, according to the different modes of operation (n = 64): control group, patients underwent modified radical mastectomy; observation group, patients underwent early breast conserving surgery. Then, the surgical indexes and prognosis were compared between these 2 groups.Intraoperative bleeding volume, incision length and hospitalization duration were better in the observation group than in the control group (P < .05). Furthermore, postoperative symptom checklist-90 scores in the observation group were better than scores before the operation, and were better than the scores in the control group (P < .05). Moreover, the incidence of postoperative complications was lower in the observation group (3.13%) than in the control group (21.88%, P < .05).Early breast-conserving surgery is more advantageous for breast cancers and results to lesser bleeding, rapid recovery, and fewer complications.

Peri-Operative Antibiotic Prophylaxis Does Not Reduce Surgical Site Infection in Breast Cancer.

Background: The reported rate of surgical site infection (SSI) in breast surgery is often higher than expected. Using antibiotic prophylaxis to reduce SSI is debatable because of the risk of developing bacteria resistance and the cost burden. In this study, we evaluated the effectiveness of antibiotic prophylaxis in breast surgery and the factors predisposing patients to SSI. Methods: A retrospective-prospective (ambispective) study was conducted in the Department of Breast Surgery, Qilu Hospital, P.R. China. The retrospective antibiotic-using group was composed of patients found to have breast cancer between January 2008 and October 2010. The prospective non-antibiotic-using group was composed of patients identified between November 2010 and November 2013. Pre-operative, peri-operative, and post-operative clinical data were analyzed. Results: The SSI rate of the non-prophylaxis and prophylaxis groups was 1.1% (11/1,022) and 1.2% (12/1,034), respectively. Neoadjuvant chemotherapy was related to SSI in the non-prophylaxis group (p = 0.026). Staphylococcus aureus was the predominant microorganism responsible for SSI, without obvious resistance to a widely used first-generation cephalosporin. Conclusions: Peri-operative antibiotic prophylaxis is of no significant value in preventing SSI in breast cancer surgery. Our results indicated that neoadjuvant chemotherapy might be a risk factor doe SSI, but further research is needed because of the sample size disparity between infected and uninfected groups.

Pectoral nerve block as the sole anesthetic technique for a modified radical mastectomy in a comorbid patient.

Breast surgery operations are generally performed by general anesthesia. In order to decrease postoperative pain, regional anesthesia is usually combined with general anesthesia. Pectoral nerve blocks is a novel technique to provide perioperative and postoperative pain control for patients underwent breast surgery. We performed pectoral nerve block I and pectoral nerve block II as a sole anesthetic technique with sedation by dexmedetomidine for modified radical mastectomy, for a 75-year-old female patient with multiple diseases. Pectoral nerve blocks with sedation could be a good technique for breast surgery than general anesthesia in comorbid patients.

Does addition of postmastectomy radiotherapy improve outcome of patients with pT1-2, N0 triple negative breast cancer as compared to breast conservation therapy?

BACKGROUND: Triple-negative breast cancers (TNBCs) form a heterogeneous group of cancers typically exhibiting an aggressive behavior resulting in increased risk of locoregional relapse (LRR) and distant metastases. The effect of radiotherapy on LRR risk and overall survival (OS) in women treated with mastectomy alone for early-stage TNBC remains unclear. AIM: The aim of this study is to compare the locoregional recurrence rate, disease-free survival (DFS), and OS following breast conservation therapy (BCT) or modified radical mastectomy (MRM) alone in women with stage I and IIA TNBC and to assess the impact of tumor and treatment-related factors. MATERIALS AND METHODS: Patients with early-stage (pT1-2, N0) TNBC-treated between January 1, 2010, and December 31, 2011, were identified from the hospital-based registry records. The mean age was 48 years. Forty-nine patients underwent BCT, and 121 underwent MRM. The majority of the patients in both groups had T2 and grade 3 disease. None of the patients had margin positive status after surgery. Five patients had lymphovascular invasion (LVI). RESULTS: At a median follow-up of 50 months (range: 4-83 months), there was no locoregional recurrence (LRR) in either arm. Eight patients relapsed, six developed distant metastases, and one patient each had a new primary in the contralateral breast and ovary. Two patients died of disseminated cancer, one each in the BCT and MRM groups. The five-year DFS was 95.8% and 91.1% for the BCT group and MRM group, respectively, (P = 0.83). The corresponding 5-year OS was 98% and 97.5% (P = 0.527). There was no statistically significant difference in outcome based on age, grade, LVI, or margin status between both groups. CONCLUSION: This retrospective analysis identified no statistically significant difference in outcome regarding LRR, DFS, or OS in patients treated without adjuvant radiation for women with pT1-T2N0 TNBC who underwent MRM in comparison to BCT.

Synchronous occurrence of lobular breast carcinoma and granulosa cell tumor of ovary mimicking metastatic lobular breast carcinoma.

Breast cancer is one of the main sources of ovarian metastasis. Diffuse sheet of lobular carcinoma cells can strongly mimic granulosa cell tumor (GCT) which itself is a rare ovarian neoplasm constituting <5% of all the ovarian neoplasms. A 55-year-old female presented with a painful lump in the right breast associated with nipple discharge for 4 months, which on radiological and cytological findings was suspicious of an epithelial malignancy. During routine work-up, a solid-cystic lesion in the left ovarian adnexa was identified. The patient underwent right modified radical mastectomy along with left salpingo-oophorectomy. Histopathological and immunohistochemical features confirmed the diagnosis of a synchronous lobular carcinoma breast with GCT ovary. Simultaneous occurrence of Lobular carcinoma breast (LCB) and GCT ovary is extremely rare. Morphologically, these can look similar, raising a suspicion of LCB metastasis to ovary. This is important to differentiate the two for a proper patient management and prognosis.

Ultrasound-Guided Pectoral Nerve Block I and Serratus-Intercostal Plane Block Alleviate Postoperative Pain in Patients Undergoing Modified Radical Mastectomy.

BACKGROUND: Simultaneous application of pectoral nerve block and serratus-intercostal plane block (SPB) is one of the most desirable multimodal analgesic strategies, with wide implementation of the enhanced recovery after surgery pathway for modified radical mastectomy (MRM). OBJECTIVES: The aim of the present study was to investigate the efficacy and safety of ultrasound-guided pectoral nerve block I (PECS I) and SPB for postoperative analgesia following MRM. STUDY DESIGN: A randomized, prospective study. SETTING: An academic medical center. METHODS: A total of 61 women undergoing MRM were randomly divided into 2 groups. The control group (group C, n = 32) received general anesthesia only, whereas the PECS I + SPB treated group (group PS, n = 29) received a combination of pectoral nerve block and SPB in addition to general anesthesia. RESULTS: Pain scores on a visual analog scale, opioid consumption, the duration at the postanesthesia care unit, and the incidence of adverse events were lower in group PS, compared with that of the group C. Moreover, PECS I together with SPB contributed to better sleep quality and higher patient satisfaction of pain relief. LIMITATIONS: This study was limited by its sample size. CONCLUSIONS: These results suggest that the combination of PECS I and SPB provide superior perioperative pain relief in breast cancer surgery. KEY WORDS: Pectoral nerve block, serratus-intercostal plane block, postoperative analgesia, modified radical mastectomy.

Effect of Flap Fixation Technique in Modified Radical Mastectomy on Incidence of Postoperative Seroma Formation.

OBJECTIVE: To determine the efficacy of flap fixation technique on formation of postoperative seroma after modified radical mastectomy. STUDY DESIGN: Quasi-experimental study. PLACE AND DURATION OF STUDY: General Surgery Department, PIMS Hospital, Islamabad, from August 2014 to February 2015. METHODOLOGY: This study included 70 female patients, aged 16 to 70 years, undergoing modified radical mastectomy, randomly divided into two groups of 35 each, Group A (flap fixation) and Group B (non-flap fixation). Flap fixation was done by suturing flaps by absorbable, fine suture to underlying pectoralis fascia to obliterate the dead space. Two closed suction drains were used in both groups. Patients were discharged on the second postoperative day. Patients and their attendants were thoroughly educated about record of drain output. Patients followed in OPD after one week. Drains were removed when fluid output was less than 50 ml/day. After removal of drains, patient were again called for weekly follow-ups in surgical OPD. Formation of seroma was diagnosed clinically as collection of fluid under the mastectomy flaps and axilla seen as fluctuant, non-tender swelling. Data was collected on proforma designed for the study and analysed by SPSS version 20.0. RESULTS: Flap fixation group had 2 (5.7%) cases of seroma formation while control group had 3 (8.6%) cases of seroma formation. The difference between both groups statistically was insignificant (p=0.643). CONCLUSION: Flap fixation technique has no statistically significant effect on reducing frequency of seroma formation in patients undergoing modified radical mastectomy.
