RESUMO

BACKGROUND: The human telomerase reverse transcriptase (hTERT) enzyme, encoded by the hTERT gene, synthesizes protective telomeric sequences on chromosomes and plays a fundamental role in cancer formation. Methylation of the hTERT gene has an upregulatory effect, increasing hTERT enzyme synthesis and allowing continuous tumor cell division. OBJECTIVE: In a group of patients with breast cancer, we aimed to analyze the methylation status of hTERT in the tumor, surrounding tissue, and circulating free deoxyribonucleic acid (cfDNA) of blood collected on the day of mastectomy and then approximately one year later. DESIGN AND SETTING: A prospective study was conducted at a university hospital in Rio de Janeiro, Brazil. METHODS: Samples were collected from 15 women with breast cancer on the day of mastectomy and approximately one year postoperatively. cfDNA was analyzed by sodium bisulfite conversion, followed by polymerase chain reaction, electrophoresis, and silver nitrate staining. RESULTS: Methylation of hTERT was detected in the tumors and surrounding tissues of all 15 patients. Five patients displayed hTERT methylation in the cfDNA from the blood of the first collection. Of the ten patients who returned for the second collection, three showed methylation. Two patients with methylation in the first collection did not display methylation in the second collection. One patient with no methylation in the first collection displayed methylation in the second collection, and one patient had a diminished level of methylation in the second collection. CONCLUSION: Only one-third of patients displayed methylation in their cfDNA, which may be related to the success of chemotherapy.

RESUMO

OBJECTIVES: The objective is to develop a pragmatic framework, based on value-based healthcare principles, to monitor health outcomes per unit costs on an institutional level. Subsequently, we investigated the association between health outcomes and healthcare utilisation costs. DESIGN: This is a retrospective cohort study. SETTING: A teaching hospital in Rotterdam, The Netherlands. PARTICIPANTS: The study was performed in two use cases. The bariatric population contained 856 patients of which 639 were diagnosed with morbid obesity body mass index (BMI) <45 and 217 were diagnosed with morbid obesity BMI ≥45. The breast cancer population contained 663 patients of which 455 received a lumpectomy and 208 a mastectomy. PRIMARY AND SECONDARY OUTCOME MEASURES: The quality cost indicator (QCI) was the primary measures and was defined asQCI = (resulting outcome * 100)/average total costs (per thousand Euros)where average total costs entail all healthcare utilisation costs with regard to the treatment of the primary diagnosis and follow-up care. Resulting outcome is the number of patients achieving textbook outcome (passing all health outcome indicators) divided by the total number of patients included in the care path. RESULTS: The breast cancer and bariatric population had the highest resulting outcome values in 2020 Q4, 0.93 and 0.73, respectively. The average total costs of the bariatric population remained stable (avg, €8833.55, min €8494.32, max €9164.26). The breast cancer population showed higher variance in costs (avg, €12 735.31 min €12 188.83, max €13 695.58). QCI values of both populations showed similar variance (0.3 and 0.8). Failing health outcome indicators was significantly related to higher hospital-based costs of care in both populations (p <0.01). CONCLUSIONS: The QCI framework is effective for monitoring changes in average total costs and relevant health outcomes on an institutional level. Health outcomes are associated with hospital-based costs of care.

RESUMO

PURPOSE: To determine the impact of the loco-regional treatment modality, on the loco-regional recurrence (LRR) rates and overall survival (OS) in breast cancer patients younger than 40 years. METHODS: Data of 623 breast cancer patients younger than 40 years of age were retrospectively reviewed. Patients were stratified according to the locoregional treatment approach into three groups: the mastectomy group (M), the mastectomy followed by radiation therapy group (MRX) and the breast conservative therapy group (BCT). RESULTS: Median follow-up was 72 months (range, 6-180). Two hundred and nine patients were treated with BCT, 86 with MRM and 328 with MRX. The 10-year rate LRR rates according to treatment modality were: 13.4% for BCT, 15.1% for MRM and 8.5% for MRX (p 0.106). On univariate analysis, T stage (p 0.009), AJCC stage (p 0.047) and Her 2 status (p 0.001) were associated with LRR. Ten-year overall survival (OS) was 72.7% (78.5% in the BCT group, 69.8% in the MRM group and 69.8% in the MRX group, p 0.072). On Univariate analysis, age < 35 (p 0.032), grade III (p 0.001), N3 stage (p 0.001), AJCC stage III (p 0.005), ER negative status (0.04), Her 2-status positive (0.006) and lack of chemotherapy administration (p 0.02) were all predictors of increased mortality. CONCLUSION: For patients younger than 40 years of age, similar LRR and overall survival outcomes were achieved using BCT, M or MRX. Young age at diagnosis should not be used alone in recommending one loco-regional treatment approach over the others.

RESUMO

OBJECTIVE: This prospective study aimed to provide a comprehensive analysis of the methylation status of two pivotal genes, CDKN2A/p16INK4A (cyclin-dependent kinase inhibitor 2A) and RB1 (retinoblastoma transcriptional corepressor 1), in breast cancer patients. METHODS: Samples were obtained from 15 women diagnosed with breast cancer and who underwent a total mastectomy. DNA was extracted from the tumor, non-tumor tissue, and peripheral blood (circulating cell-free DNA). The methylation pattern of cell-free DNA extracted from blood collected on the day of mastectomy was compared with the methylation pattern of cell-free DNA from blood collected 1 year post-surgery. The methylation analysis was carried out by sodium bisulfite conversion and polymerase chain reaction, followed by electrophoresis. RESULTS: Methylation of CDKN2A/p16INK4A was identified in 13 tumor samples and 12 non-tumor tissue samples. Two patients exhibited CDKN2A/p16INK4A methylation in the cell-free DNA of the first blood collection, while another showed methylation only in the cell-free DNA of the subsequent blood collection. Regarding RB1, 11 tumors and 8 non-tumor tissue samples presented methylation of the gene. CONCLUSION: This study presents a novel approach for monitoring breast cancer patients through the analysis of cell-free DNA methylation. This analysis can detect changes in methylation patterns before any visible sign of cancer appears in breast tissue and could help predict the recurrence of malignant breast tumors.

RESUMO

Sentinel node biopsy (SNB) is routinely performed in people with node-negative early breast cancer to assess the axilla. SNB has no proven therapeutic benefit. Nodal status information obtained from SNB helps in prognostication and can influence adjuvant systemic and locoregional treatment choices. However, the redundancy of the nodal status information is becoming increasingly apparent. The accuracy of radiological assessment of the axilla, combined with the strong influence of tumour biology on systemic and locoregional therapy requirements, has prompted many to consider alternative options for SNB. SNB contributes significantly to decreased quality of life in early breast cancer patients. Substantial improvements in workflow and cost could accrue by removing SNB from early breast cancer treatment. We review the current viewpoints and ideas for alternative options for assessing and managing a clinically negative axilla in patients with early breast cancer (EBC). Omitting SNB in selected cases or replacing SNB with a non-invasive predictive model appear to be viable options based on current literature.

RESUMO

Objective: The purpose of this study was to compare postoperative pain between SF flap and serratus anterior muscle (SM) in direct-to-implant breast reconstruction. Methods: This is a prospective cohort study that included 53 women diagnosed with breast cancer who underwent mastectomy and one-stage implant-based breast reconstruction from January 2020 to March 2021. Twenty-nine patients (54.7%) had SF elevation, and 24 patients (45.3%) underwent SM elevation. We evaluated patient-reported early postoperative pain on the first day after surgery. Also, it was reported that all surgical complications in the first month and patient reported outcomes (PROs) were measured with the BRECON 23 questionnaire. Results: The serratus fascia group used implants with larger volumes, 407.6 ± 98.9 cc (p < 0.01). There was no significant difference between the fascial and muscular groups regarding the postoperative pain score reported by the patients (2 versus 3; p = 0.30). Also, there was no difference between the groups regarding early surgical complications and PROs after breast reconstruction. Conclusion: The use of SF seems to cause less morbidity, which makes the technique an alternative to be considered in breast reconstruction. Although there was no statistical difference in postoperative pain scores between the fascia and serratus muscle groups.

RESUMO

BACKGROUND: Persistent pain is a common yet debilitating complication after breast cancer surgery. Given the pervasive effects of this pain disorder on the patient and healthcare system, post-mastectomy pain syndrome (PMPS) is becoming a larger population health problem, especially as the prognosis and survivorship of breast cancer increases. Interventions that prevent persistent pain after breast surgery are needed to improve the quality of life of breast cancer survivors. An intraoperative intravenous lidocaine infusion has emerged as a potential intervention to decrease the incidence of PMPS. We aim to determine the definitive effects of this intervention in patients undergoing breast cancer surgery. METHODS: PLAN will be a multicenter, parallel-group, blinded, 1:1 randomized, placebo-controlled trial of 1,602 patients undergoing breast cancer surgery. Adult patients scheduled for a lumpectomy or mastectomy will be randomized to receive an intravenous 2% lidocaine bolus of 1.5 mg/kg with induction of anesthesia, followed by a 2.0 mg/kg/h infusion until the end of surgery, or placebo solution (normal saline) at the same volume. The primary outcome will be the incidence of persistent pain at 3 months. Secondary outcomes include the incidence of pain and opioid consumption at 1 h, 1-3 days, and 12 months after surgery, as well as emotional, physical, and functional parameters, and cost-effectiveness. DISCUSSION: This trial aims to provide definitive evidence on an intervention that could potentially prevent persistent pain after breast cancer surgery. If this trial is successful, lidocaine infusion would be integrated as standard of care in breast cancer management. This inexpensive, widely available, and easily administered intervention has the potential to reduce pain and suffering in an already afflicted patient population, decrease the substantial costs of chronic pain management, potentially decrease opioid use, and improve the quality of life in patients. TRIAL REGISTRATION: This trial has been registered on clinicaltrials.gov (NCT04874038, Dr. James Khan. Date of registration: May 5, 2021).

RESUMO

Radiotherapy is important in breast cancer treatment. A side effect of the treatment is fibrosis that decreases the possibility for a successful breast reconstruction with expanders and with high patient satisfaction with the result. The most common option for mastectomized, irradiated women wishing for a breast reconstruction is autologous tissue transplantation. However, some patients are not suitable for flap surgery. Fifty mastectomized and irradiated women were included in a randomized controlled trial. They underwent breast reconstruction with expanders and were allocated 1:1 to either receive pre-treatment with autologous fat transplantation (AFT) or not. Primary outcomes were frequency of reoperations and complications. Secondary outcomes were number of days in hospital, number of outpatient visits to surgeon or nurse and patient reported outcome as reported with Breast Q. Follow-up time was 2 years. Fifty-two per cent of the intervention group and 68% of the controls underwent reoperations (p = 0.611). Thirty-two per cent of the intervention group and 52% of the controls had complications (p = 0.347). The median number of consultations with the nurse was four in the intervention group and six in the control group (p = 0.002). The AFT patients were significantly more satisfied with their breasts and psychosocial well-being after 2 years. They also had higher increase in satisfaction with breasts, psychosocial well-being, and sexual well-being when comparing baseline with 2 years postoperatively. This randomized controlled trial indicates benefits of AFT prior to breast reconstruction with expanders, especially on patient reported outcome even if the study sample is small.

RESUMO

BACKGROUND: Social anxiety among postoperative breast cancer patients is a prevalent concern, with its intensity fluctuating throughout the course of treatment. The study aims to describe the trajectory of social anxiety in postoperative breast cancer patients, explore the influencing factors, and provide theoretical support for the construction of future intervention programs. METHODS: This study was conducted from June 2022 to January 2023, encompassing 213 breast cancer patients from three first-class hospitals in China. Data collection occurred at four distinct time points. A growth mixture model was employed to identify latent categories representing the trajectories of social anxiety changes among patients. A multiple regression analysis was utilized to explore predictive factors associated with different latent trajectory categories. RESULTS: The trajectory of social anxiety changes in postoperative breast cancer patients includes five potential categories: maintaining mild social anxiety group, changing from mild to moderate social anxiety group, maintaining moderate social anxiety group, changing from moderate to severe social anxiety group, and maintaining severe social anxiety group. Cluster analysis results indicated three types: positive, negative, and low. Logistic regression analysis revealed that younger age, spouses concerned about postoperative appearance, chemotherapy with taxol-based drugs, opting for modified radical surgery or radical mastectomy surgical approaches, and breast cancer patients with negative rumination were factors that influenced patients' social anxiety (P < 0.05). CONCLUSION: The trajectory of social anxiety in postoperative breast cancer patients comprises five potential categories. In clinical practice, it is essential to strengthen the management of high-risk populations susceptible to experiencing social anxiety emotions, including younger age, spouses concerned about postoperative appearance, chemotherapy with taxol-based drugs, opting for modified radical surgery or radical mastectomy surgical approaches, and breast cancer patients with negative rumination.

RESUMO

BACKGROUND: Statins are a group of lipid-lowering drugs with pleiotropic effects that include, but are not limited to the inhibition of cholesterol synthesis resulting in a wide range of anti-inflammatory, anti-tumor, immunomodulatory, and anti-thrombotic properties. This study aimed to determine the impact of the prior to- or after- breast surgery usage of statins on the tumor prognosis in breast cancer (BC) patients. METHODS: A cohort of patients diagnosed with early invasive ductal BC (n=301) at the Hospital Italiano de Buenos Aires, Argentina, with a minimum follow-up period of 10 years after the surgical procedure were included and stratified according to the time of use of statins and type of statin used. Then, local relapse-free survival (RFS), metastasis-free survival (MFS), bone metastasis-free survival (BMFS), visceral metastasis-free (VMFS), mixed metastasis (bone and visceral)-free survival (mix-MFS) and overall survival (OS) were analyzed. RESULTS: Statins usage after breast surgery was related with lesser metastatic occurrence (p=0.017), lower number of metastatic foci (p=0.034) and fewer dead events (p=0.041), as well as longer MFS (p=0.013) and OS (p=0.027). When stratified by the nature of statins (hydrophilic or lipophilic), only the relatively hydrophilic statin rosuvastatin (ROSU) had an impact on the increase of MFS and OS (p=0.018 and p=0.030, respectively). CONCLUSION: Post-surgery statins usage was associated with increased MFS and OS, with increased benefits of ROSU over simvastatin (SIM) or atorvastatin (ATOR). These results set the rationale for additional studies addressing the use of statins, and particularly, rosuvastatin, to improve the outcome of BC patients.

RESUMO

Radiotherapy (RT) is one of the major treatment modalities among surgery and chemotherapy for carcinoma breast. The surface dose study of modified reconstructive constructive Mastectomy (MRM) breast is important due to the heterogeneity in the body contour and the conventional treatment angle to save the lungs and heart from the radiation. These angular entries of radiation beam cause an unpredictable dose deposition on the body surface, which has to be monitored. Thermoluminescent dosimeter (TLD) or optically stimulated luminescent dosimeter (nano OSLD) are commonly preferable dosimeters for this purpose. The surface dose response of TLD and nano OSLD during MRM irradiation has been compared with the predicted dose from the treatment planning system (TPS). The study monitored 100 MRM patients by employing a total 500 dosimeters consisting of TLD (n = 250) and nano OSLD (n = 250), during irradiation from an Elekta Versa HD 6 MV Linear accelerator. The study observed a variance of 3.9% in the dose measurements for TLD and 3.2% for nano OSLD from the planned surface dose, with a median percentage dose of 44.02 for nano OSLD and 40.30 for TLD (p value 0.01). There was no discernible evidence of variation in dose measurements attributable to differences in field size or from patient to patient. Additionally, no variation was observed in dose measurements when comparing the placement of the dosimeter from central to off-centre positions. In comparison, a minor difference in dose measurements were noted between TLD and nano OSLD, The study's outcomes support the applicability of both TLD and nano OSLD as effective dosimeters during MRM breast irradiation for surface dose evaluation.

RESUMO

ABSTRACT: This study aimed to determine whether there is a difference in free flap failure based on the decision to undergo immediate versus delayed autologous tissue breast reconstruction after mastectomy. The National Surgical Quality Improvement Program database was queried for breast free flap procedures performed between 2015 and 2020. This study demonstrates that the decision to undergo immediate versus delayed autologous tissue breast reconstruction does not have a significant association with free flap failure. This remains true regardless of whether patients undergo unilateral mastectomy with reconstruction or whether patients choose to also undergo contralateral prophylactic mastectomy with reconstruction.

RESUMO

BACKGROUND: About 30% to 50% of women with breast cancer undergo mastectomy, and approximately 50% of them will receive adjuvant radiotherapy (ART). This study evaluates the medium- and long-term impact of ART after immediate breast reconstruction (IBR) with latissimus dorsi myocutaneous (LDM) flap and silicone implants. METHODS: Clinical, surgical, and oncological data were retrospectively collected and analyzed based on the medical records of 176 patients who had undergone IBR with LDM flap and silicone implants. RESULTS: The data showed that 7.4% of patients had a history of previous radiotherapy, 56.3% received ART, 31.8% developed capsular contracture with a mean follow-up of 58.1 months, and 14.2% of surgeries were categorized as procedures with a prolonged operating time, lasting above 1 SD of the observed mean. Those who experienced prolonged operating time (odds ratio, 4.72; 95% confidence interval, 1.72-12.93; P = 0.003) and those who received ART (odds ratio, 7.38; 95% confidence interval, 3.18-17.10; P < 0.001) were more likely to develop capsular contracture. Thirty-two patients (18%) underwent capsulectomy with implant replacement, and 7 patients (4%) had the implant removed. The mean time between IBR and reoperation was 29.1 months. Patients who received ART were 2.84 times more likely to experience reconstruction failure or undergo implant-related reoperation ( P = 0.002). CONCLUSIONS: The results indicated that IBR with LDM flap and silicone implant followed by ART is a safe procedure, resulting in low rates of reconstruction failure. However, ART increased the likelihood of capsular contracture development and implant-related reoperation, having a negative effect on reconstructed breasts.

RESUMO

Superficial inferior epigastric artery (SIEA) flap is often chosen to minimize postoperative complications such as abdominal pain and bulging. However, drawbacks, including a small diameter and a short pedicle, pose challenges in anastomosing or creating the lower pole of the breast. Here, we report a case of breast reconstruction using an SIEA flap with pedicle elongation via an arteriovenous loop (AV-loop) using a contralateral superficial inferior epigastric vein (SIEV) graft. A 49-year-old woman underwent a left total mastectomy with the primary insertion of a tissue expander. Breast reconstruction using an SIEA flap with pedicle elongation was planned. The running pattern, pedicle length, and diameter of bilateral SIEA/SIEV and superficial circumflex iliac artery and vein (SCIA/SCIV) were evaluated preoperatively using a 48-MHz probe of ultra-high-frequency ultrasonography (Vevo MD ultrasound device, Fujifilm Visual Sonics, Amsterdam, the Netherlands). During the flap harvesting, the contralateral SIEV graft was harvested to create an AV-loop for pedicle elongation. The 9 cm graft was anastomosed to the left internal mammary artery and vein (IMA/IMV). After the flap elevation, the created AV-loop was divided at the midpoint and anastomosed to the pedicle of the SIEA flap. The SIEA flap, extended with a SIEV AV-loop, facilitated the augmentation of the lower pole of the breast without the risk of pedicle kinking and pulling. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. The prolonged pedicle length via an AV-loop prevents the pedicle kinking and allows for positioning the flap more freely, resulting in an aesthetically good breast contour by filling in the lower pole. The precise preoperative evaluation of the vessels using ultra-high-frequency ultrasonography facilitated meticulous planning. In cases where surgeons aim to minimize intraoperative and postoperative complications associated with other abdominal free flaps, this method may be considered a viable and promising option.

RESUMO

BACKGROUND: Breast-conserving surgery with adjuvant radiotherapy and mastectomy are currently offered as equivalent surgical options for early-stage breast cancer based on RCTs from the 1970s and 1980s. However, the treatment of breast cancer has evolved and recent observational studies suggest a survival advantage for breast-conserving surgery with adjuvant radiotherapy. A systematic review and meta-analysis was undertaken to summarize the contemporary evidence regarding survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for women with early-stage breast cancer. METHODS: A systematic search of MEDLINE, the Cochrane Central Register of Controlled Trials (CENTRAL), and Embase that identified studies published between 1 January 2000 and 18 December 2023 comparing overall survival after breast-conserving surgery with adjuvant radiotherapy versus mastectomy for patients with unilateral stage 1-3 breast cancer was undertaken. The main exclusion criteria were studies evaluating neoadjuvant chemotherapy, rare breast cancer subtypes, and specific breast cancer populations. The ROBINS-I tool was used to assess risk of bias, with the overall certainty of evidence assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Studies without critical risk of bias were included in a quantitative meta-analysis. RESULTS: From 11 750 abstracts, 108 eligible articles were identified, with one article including two studies; 29 studies were excluded from the meta-analysis due to an overall critical risk of bias, 42 studies were excluded due to overlapping study populations, and three studies were excluded due to reporting incompatible results. A total of 35 observational studies reported survival outcomes for 909 077 patients (362 390 patients undergoing mastectomy and 546 687 patients undergoing breast-conserving surgery with adjuvant radiotherapy). The pooled HR was 0.72 (95% c.i. 0.68 to 0.75, P < 0.001), demonstrating improved overall survival for patients undergoing breast-conserving surgery with adjuvant radiotherapy. The overall certainty of the evidence was very low. CONCLUSION: This meta-analysis provides evidence suggesting a survival advantage for women undergoing breast-conserving surgery with adjuvant radiotherapy for early-stage breast cancer compared with mastectomy. Although these results should be interpreted with caution, they should be shared with patients to support informed surgical decision-making.

RESUMO

Women with breast cancer show dissatisfaction with their appearance, a perception of loss of femininity and bodily integrity, and dissatisfaction with the outcome of the surgery. Body Appreciation (BA) is defined as positive attitudes toward one's body, beyond satisfaction and dissatisfaction with one's appearance. Although studies about the protective role of BA have increased, to the best of our knowledge, there are no published studies on the association between BA, body dissatisfaction, and distress in participants with breast cancer. The aims of this study are: (a) To analyze whether BA is a moderator of satisfaction with the body from before breast surgery to the one-year follow-up; and (b) to analyze whether BA is a moderator of distress from before breast surgery to the one-year follow-up. The sample consisted of 115 women diagnosed with breast cancer. Several hierarchical regression analyses were conducted. The results indicated that BA moderated the association between the appearance evaluation before the surgery and the appearance evaluation 12 months after the surgery. Although BA was a significative predictor of distress, it was not a moderator of distress from the moment before breast surgery to the one-year follow-up. This study highlights the importance of evaluating the construct of BA in participants with breast cancer using longitudinal designs and developing psychological interventions that focus on increasing BA.

RESUMO

BACKGROUND: Supermicrosurgical advances such as lymphovenous bypass (LVB) have enabled effective physiologic treatment of lymphedema affecting the extremities. Reports of surgical treatment for breast lymphedema (BL) are sparse, consisting of case reports and almost exclusively LVB. We report our experience with BL, including a case of mastectomy and breast reconstruction with abdominal free flap and inguinal vascularized lymph node transfer (VLNT) for BL. We compare our series with the surgical literature to discern unique characteristics and treatment limitations inherent to this disease. METHODS: A database was prospectively maintained from September 2020 to May 2023 including all patients diagnosed with BL who were referred to our institution. Breast lymphedema was diagnosed using clinical criteria, and relevant patient data were recorded. Patients interested in surgical management underwent indocyanine green lymphography to determine candidacy for LVB or other interventions. All patients, including those surgically managed, were treated with complex decongestive therapy. RESULTS: Nine patients with BL were included. Eight had undergone breast-conserving therapy for breast cancer with whole breast irradiation. One patient was treated for Hodgkin lymphoma with axillary lymphadenectomy and axillary radiation. Indocyanine green lymphography was performed in 6 patients, of which 4 patients had diffuse dermal backflow. Two patients had lymphatic targets suitable for LVB, including the patient without breast irradiation. Three patients were managed surgically. One patient without bypass targets underwent breast reduction with partial symptomatic relief, later followed by a mastectomy with abdominal free flap reconstruction and VLNT. Two patients with suitable bypass targets underwent LVB, with resolution of breast swelling and subjective symptoms. CONCLUSIONS: The diffuse lymphatic obliteration due to radiation field effect in BL results in a distinct pathophysiology compared with extremity lymphedema. Although published reports of surgical BL treatment almost exclusively describe LVB, other surgical options may be more frequently required. Ablative strategies such as mastectomy and regenerative techniques such as VLNT should be considered potential first-line treatment options for these patients.

RESUMO

To determine the impact of breast conservation on quality of life and identify treatment-related and other demographic factors associated with post-breast cancer treatment quality of life. A prospective study was conducted on 392 women who underwent breast cancer surgery at Hangzhou Cancer Hospital from January 1, 2013, to December 31, 2022. Operable breast cancer patients who had completed all treatments except endocrine therapy were included. Patients with tumor recurrence/metastasis, bilateral or male breast cancer, and other primary malignancies were excluded. After enrollment, patients were asked to complete the BREAST-Q scale, and their pathological and medical records were reviewed. Analysis of variance was used to compare the quality of life scores among the groups. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with quality of life scores in different domains. Participants completed the BREAST-Q scale at a median of 4.6 years after surgery. Quality of life scores varied based on the therapeutic strategy. Breast conservation has significant advantages over mastectomy in terms of breast satisfaction, psychosocial, and sexual well-being. Compared to oncoplastic breast-conserving surgery, mastectomy was independently associated with decreased breast satisfaction, psychosocial, and sexual well-being, while conventional breast-conserving surgery showed comparable outcomes to oncoplastic breast-conserving surgery in terms of these factors. Breast conservation leads to an improvement in quality of life compared to mastectomy. Oncoplastic breast-conserving surgery does not lead to a decrease in quality of life compared to conventional breast-conserving surgery and offers better outcomes compared to mastectomy.

RESUMO

PURPOSE: Results from the TAILORx trial revealed that the use of adjuvant chemotherapy along with endocrine therapy had no survival advantage in patients with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2-negative (HER2-), node-negative (N0) breast cancer (BC) with an intermediate (11-25) 21-gene recurrence score (RS) in the overall population. However, in patients under age 50 years, adjuvant chemotherapy demonstrated a progression-free survival benefit when the RS ranged from 16-25. We studied this cohort with the population-based national database. METHODS: The 2010-2018 National Cancer Database was used to include patients with BC age 18-50 years, N0, M0, RS 16-25, ER+/progesterone receptor±, and HER2-. Patients were divided into two groups on the basis of adjuvant chemotherapy use, and the survival between them was compared. RESULTS: Adjuvant chemotherapy use was noted in 4,808/15,792 (30.45%) patients. Median RS was 18 and 21 in patients without and with adjuvant chemotherapy, respectively. Factors associated with adjuvant chemotherapy use were higher T stage, poor and moderately differentiated tumors, age <40 years, care at an academic center, Caucasian race, patients undergoing mastectomy, regional lymph node surgery, and radiation therapy. Kaplan-Meier survival at 10 years was better with adjuvant chemotherapy (96.2% v 91.6%). Patients without adjuvant chemotherapy had more adverse outcomes (hazard ratio [HR], 1.683 [95% CI, 1.392 to 2.036]; P < .0001). Subgroup analysis showed that the benefit was significant in patients with RS scores 21-25 (HR, 1.953 [95% CI, 1.295 to 2.945]), ductal histology (HR, 1.521 [95% CI, 1.092 to 2.118]), Caucasian race (HR, 1.655 [95% CI, 1.180 to 2.322]), and 41-50 years age group (HR, 1.732 [95% CI, 1.244 to 2.411]). CONCLUSION: Our study showed an overall survival benefit for adjuvant chemotherapy use in patients with ER-positive, N0 premenopausal BC patients, age less than 50 years, with an intermediate RS score, particularly 21-25.
