ABSTRACT

OBJECTIVE: Phyllodes tumors in the breast are exceptionally uncommon fibroepithelial tumors. In the literature, they are typically categorized as benign phyllodes tumor, borderline phyllodes tumor, and malignant phyllodes tumor. This study aims to assess and present the clinical and surgical outcomes of patients diagnosed with phyllodes tumor. METHODS: The outcomes of patients aged 18 years and above diagnosed with phyllodes tumor between 2006 and 2023 were retrospectively reviewed. Patients were grouped as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared by clinical and surgical results. RESULTS: Of all 57 patients with phyllodes tumor, 64.9% (n=37) were benign phyllodes tumor and 35.1% (n=20) were borderline/malignant phyllodes tumor [22.8% (n=13) borderline phyllodes tumor and 12.3% (n=7) malignant phyllodes tumor]. When the patients were divided into two groups as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared, our cumulative (total) recurrence rate was 14.0%, with final surgical margin width between groups [(0

ABSTRACT

PURPOSE: To assess whether health-related quality of life (HRQOL) improved through a postmastectomy care program focused on breast cancer-related lymphedema (BCRL) protection/awareness. METHODS: Postoperative breast cancer patients were enrolled prospectively (February-2018 to September-2019) at Nursing and Obstetrics Faculty, Durango, Mexico. Sociodemographic/clinical characteristics, arm measurements, and HRQOL evaluation with Functional Assessment Cancer Therapy-Breast Cancer were collected at baseline and after six follow-up assessments between six-to-twelve-month postmastectomy. Lymphedema was verified through circometry. Descriptive analysis and McNemar-Bowker test were used to evaluate paired differences in HRQOL. Subgroup analysis was conducted to assess sociodemographic/clinical characteristics of BCRL using Pearson's chi-squared or Fisher exact test along with odds ratios (OR) and 95% confidence intervals (CI). All tests were two-sided with P-values < 0.05 considered statistically significant. RESULTS: One-hundred-two patients developed BCRL (incidence 66.2%, n = 154). All dimensions of HRQOL improved after the postmastectomy care program (P < 0.05). The subgroup analysis indicated that elementary academic degree (OR = 2.40, 95%CI: 1.01-5.69), laborer (OR = 9.85, 95%CI: 3.30-29.3), and total mastectomy (OR = 4.23, 95%CI: 1.20-14.9) were more associated with BCRL (P < 0.05). Conversely, high school academic degree (OR = 0.46, 95%CI: 0.22-0.94), married status (OR = 0.42, 95%CI: 0.21-0.86), housewife (OR = 0.27, 95%CI: 0.12-0.61), professional occupation (OR = 0.10, 95%CI: 0.01-0.64), and having no comorbidities (OR = 0.31, 95%CI: 0.15-0.63) were less associated with BCRL (P < 0.05). CONCLUSION: Although HRQOL improved through the postmastectomy care program, our findings suggest that lower education, working as a laborer, and total mastectomy may be more associated with BCRL. Continuing research may uncover liabilities among BCRL patients within limited-resources settings.

ABSTRACT

INTRODUCTION: Seroma is the most common early complication following surgical breast cancer treatment. Its development is associated with pain, scar complications, adjuvant therapy delays, the need for outpatient visits, and increased care costs. OBJECTIVE: Assess seroma incidence and risk factors in women undergoing mastectomies. METHOD: This study comprises a prospective cohort encompassing women aged 18 or over undergoing mastectomies as a breast cancer treatment. Patients underwent physiotherapy on the 1st, 7th, and 30th postoperative days for kinetic-functional, skin, and wound healing assessments and were attended to by nurses for surgical wound care, draining liquid on the 7th, 14th, and 21st postoperative days. Seroma was defined as the presence of local fluctuations requiring puncture, regardless of the punctured volume. RESULTS: A total of 249 women were evaluated, with a mean age of 57.5 (SD = 11.8). A total of 77.1% were classified as overweight or obese, 60.2% were hypertensive, 21.3% were diabetic, 66.7% underwent neoadjuvant chemotherapy and 62.7% underwent axillary lymphadenectomies. Seroma incidence was 71.1%, requiring, on average, two aspiration punctures until condition resolution. Overweight or obese women and those who underwent axillary lymphadenectomies exhibited 1.92- and 2.06-fold higher risk for seroma development (OR = 1.92; 95% CI 1.02-3.61; p = 0.042; and OR = 2.06; 95% CI 1.17-3.63; p = 0.012), respectively. CONCLUSION: Seroma incidence was very high. Being overweight or obese and undergoing axillary lymphadenectomy comprise independent seroma development risk factors. This study is part of a randomized clinical trial evaluating the effectiveness of applying compressive taping to prevent post-mastectomy seroma, which was approved by the Brazilian National Cancer Institute, Research Ethics Committee (2,774,824), and it is registered in the ClinicalTrials.gov (NCT04471142, on July 15, 2020).

ABSTRACT

El dolor es un síntoma frecuente de presentación en los casos de cáncer pulmonar y es un dolor refractario debido a la multiplicidad de generadores de dolor. Las presentaciones pueden ser una invasión pleural, metastasis costales, invasión mixta o síndrome costo-pleural, tumor de Pancoast, y metástasis vertebral con o sin invasion paravertebral. Se han desarrollado terapias intervencionales mínimamente invasivas para tratar el dolor, que en etapas tempranas en pacientes con dolor no controlado mejoran su condición de salud, mejoran su rendimiento para enfrentar la enfermedad y su tratamiento, y evitan o retrasan la escalada de opioides con sus efectos adversos asociados. Se requiere estandarizar las técnicas, mejorar la calidad de los ensayos clínicos y desarrollar guías de práctica clínica en un trabajo conjunto con oncología.


Pain is a frequent presenting symptom in cases of lung cancer and it is a refractory pain due to the multiplicity of pain generators. Clinical presentations may be pleural invasion, rib metastasis, mixed invasion or costo-pleural syndrome, Pancoast tumor, and vertebral metastasis with or without paravertebral invasion. Minimally invasive interventional therapies have been developed to treat pain, which in early stages in patients with uncontrolled pain improve their health condition, improve their performance in coping with the disease and its treatment, and prevent or delay the escalation of opioids with their associated side effects. It is necessary to standardize the techniques, improve the quality of clinical trials and develop clinical practice guidelines in a joint effort with oncology.

ABSTRACT

INTRODUCTION: Breast cancer (BC) and its treatment can impair patient quality of life (QoL), and those undergoing more aggressive treatments may be more severely impacted. Objective: Assess the level of perception of the QoL of patients treated for BC at the Hospital de Clínicas and the Departmental Hospital of Soriano. MATERIALS AND METHODS: A questionnaire for cancer patients (EORTC, QLQ-C30) and one specific for BC (EORTC QLQ-BR23) were used. RESULTS: A total of 158 patients who had completed chemotherapy treatment at least one year prior to the evaluation were enrolled. The average age was 61 years old. QLQC QUESTIONNAIRE: The global QoL score (GQOL) was high: 70.9. Patients undergoing breast-conservation surgery (BCS) had better scores in physical and emotional functioning (p < 0.005) and presented less frequently with: pain, constipation, and financial difficulties (p < 0.005). Those undergoing sentinel lymph node biopsy (SLNB) had higher scores for GQOL and for physical, role, and social functioning scales (p < 0.001) and had less fatigue, pain, insomnia, and financial difficulties (p < 0.005). QUESTIONNAIRE QLQBR: Sexual functioning and sexual enjoyment scales were relatively low. Patients undergoing BCS had better scores on the functional scales: body image and future outlook; and fewer breast symptoms (p < 0.005). Those undergoing SLNB also had better scores on the functional scales for body image and future outlook future and presented less frequently with symptoms (p < 0.005). CONCLUSION: Uruguayan BC patients experience high values on the GQOL scale; those undergoing BCS and SLNB had better scores on most functional and problem/symptom scales. Patients undergoing BCS had better scores in physical and emotional functioning and presented less frequently with pain, constipation, and financial difficulties. With respect to the type of axillary surgery received, patients who underwent SLNB had higher scores on the GQOL scale and on the physical, role, and social functional scales. The implementation of intervention strategies aimed at improving the quality of life, and the physical and emotional care of patients is recommended.

ABSTRACT

BACKGROUND: The purpose of this study was to review and summarize the association between preoperative magnetic resonance imaging (MRI) and surgical outcomes in women with newly diagnosed invasive breast cancer from published randomized controlled trials (RCT). MATERIALS AND METHODS: Two independent researchers conducted a systematic review through a comprehensive search of electronic databases, including PubMed, Medline, Embase, Ovid, Cochrane Library, and Web of Science. If there was disagreement between the two reviewers, a third reviewer assessed the manuscript to determine whether it should be included for data extraction. The quality of the papers was assessed using the risk of bias tool, and the evidence was analyzed using GRADE. Meta-analyses using a fixed-effects model were used to estimate the pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS: Initially, 21 studies were identified, 15 of which were observational comparative studies. A total of five RCTs were included, and they suggested that preoperative MRI significantly reduced the rate of immediate breast-conserving surgery and increased the risk for mastectomy. CONCLUSIONS: From the RCT perspective, preoperative MRI for newly diagnosed invasive breast cancer did not improve surgical outcomes and may increase the risk of mastectomy.

ABSTRACT

OBJECTIVE: The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction. METHODS: A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction. We also assessed the Brazilian experience in oncoplastic centers. RESULTS: The basis for educational discussions was derived from 16 articles. We observed approaches that included hands-on courses utilizing simulator models, porcine models, cadaver labs, and fellowship programs. Positive outcomes were observed in Brazil, a fact based on seven oncoplasty training centers for senior mastologists and five training centers for junior mastologists. From 2009 to 2023, an estimated 452 seniors and 42 juniors received training, representing approximately 30% of mastologists in Brazil who have acquired training and experience in oncoplasty. CONCLUSION: Despite the limited number of publications on training methods, oncoplastic centers have made significant progress in Brazil, establishing a successful model that can be replicated in other countries.

ABSTRACT

Breast cancer, or breast neoplasm, is one of the most frequent types of cancer, and one of the most prevalent among women. The diagnosis and specific treatments, such as mastectomy surgery, lead women to experience different feelings, with the most predominant negative thoughts. In this way, the objective of this study is to describe the importance of nursing care in the face of the psycho-emotional aspects of women after mastectomy. This is an integrative literature review study, developed in electronic Medline and Lilacs databases. The following terms were used: Breast neoplasm; Nursing; Emotions; Mastectomy. A total of 2,314 articles were found, of which eight were selected. The results and discussions were divided into two thematic axes: The first deals with the emotions of women after mastectomy, whose feelings arising from the diagnosis of the disease start to affect different areas, such as personality, sexuality, family, and social relationships. Furthermore, the second deals with nursing care after mastectomy, which must be conducted integrally, aiming at restoring physical and emotional health. Nursing is the vehicle capable of planning and collaborating with these women, promoting humanized treatment and assistance, oriented and aimed at a better quality of life, and stimulating self-help, self-esteem, and acceptance of their body.


O câncer de mama ou neoplasia da mama, é um dos tipos de cânceres mais frequentes, e um dos mais prevalentes entre as mulheres. O diagnóstico e determinados tratamentos, como a cirurgia de mastectomia, levam as mulheres a vivenciarem diferentes sentimentos, sendo os pensamentos negativos os mais predominantes. Desta maneira, o objetivo deste estudo é descrever a importância da assistência do enfermeiro frente aos aspectos psicoemocionais de mulheres mastectomizadas. Trata-se de um estudo de revisão integrativa da literatura, desenvolvida nas bases eletrônicas de dados Medline e Lilacs. Foram utilizados os seguintes descritores: Neoplasias da mama; Enfermagem; Emoções; Mastectomia. Foram encontrados 2314 artigos, dos quais foram selecionados oito. Os resultados e discussões foram divididos em dois eixos temáticos: O primeiro trata das emoções das mulheres mastectomizadas, cujos sentimentos advindos com o diagnóstico da doença passam a afetar diferentes aspectos psicoemocionais, como personalidade, sexualidade, família e relações sociais. E o segundo trata da assistência de enfermagem após a mastectomia, a qual deve se dar de maneira integral, visando tanto o restabelecimento da saúde física quanto emocional. A enfermagem pode desempenhar um cuidado diferenciado e voltado para as necessidades psicoemocionais das mulheres, promovendo tratamento e assistência humanizados, orientados e voltados a uma melhor qualidade de vida, e com o fim de estimular a autoajuda, a autoestima e a aceitação de seu corpo.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE: To compare the effects of constant rate infusions (CRI) of fentanyl or dexmedetomidine, combined with lidocaine and ketamine, on cardiovascular response during surgery, sevoflurane requirement and postoperative pain in dogs undergoing mastectomy. STUDY DESIGN: Prospective, randomized, blinded, clinical trial. ANIMALS: A total of 29 female dogs with mammary tumors. METHODS: Premedication consisted of intramuscular acepromazine and morphine. General anesthesia was induced with intravenous propofol and maintained with sevoflurane. Dogs were randomized to be administered intravenous DLK [dexmedetomidine 1 µg kg-1 loading dose (LD) and 1 µg kg-1 hour-1; lidocaine 2 mg kg-1 LD and 3 mg kg-1 hour-1; ketamine 1 mg kg-1 LD and 0.6 mg kg-1 hour-1; n = 14] or FLK (fentanyl 5 µg kg-1 LD and 9 µg kg-1 hour-1; same doses of lidocaine and ketamine; n = 15) during anesthesia. Cardiorespiratory variables and end-tidal sevoflurane (Fe'Sevo) were recorded during surgery. The number of dogs administered ephedrine to treat arterial hypotension [mean arterial pressure (MAP) < 60 mmHg] was recorded. Meloxicam was administered to both groups. Postoperative pain and rescue analgesia requirement were assessed for 24 hours using the short form of the Glasgow Composite Measure Pain Scale. Data were compared using a mixed effects model or a Mann-Whitney test. RESULTS: More dogs required ephedrine in FLK than in DLK (67% versus 7%). Heart rate was not significantly different between groups, whereas lower values of MAP (p ≤ 0.01) and Fe'Sevo (p = 0.018) were observed in FLK than in DLK. Rescue analgesia was administered to 2/15 dogs in FLK and 0/14 dogs in DLK. CONCLUSIONS AND CLINICAL RELEVANCE: Based on the cardiovascular response during surgery, intraoperative infusions of FLK and DLK provided adequate antinociception. Infusion of DLK provided greater stability of blood pressure. Both protocols resulted in minimal need for additional analgesia within 24 hours postoperatively.

ABSTRACT

BACKGROUND: A recent large, well-annotated international cohort of patients with Li-Fraumeni syndrome and early-stage breast cancer was examined for shared features. METHODS: This multicenter cohort study included women with a germline TP53 pathogenic or likely pathogenic variant and nonmetastatic breast cancer diagnosed between 2002 and 2022. Clinical and genetic data were obtained from institutional registries and clinical charts. Descriptive statistics were used to summarize proportions, and differences were assessed using χ2 or Wilcoxon rank sum tests. Metachronous contralateral breast cancer risk, radiation-induced sarcoma risk, and recurrence-free survival were analyzed using the Kaplan-Meier methodology. RESULTS: Among 227 women who met study criteria, the median age of first breast cancer diagnosis was 37 years (range = 21-71), 11.9% presented with bilateral synchronous breast cancer, and 18.1% had ductal carcinoma in situ only. In total, 166 (73.1%) patients underwent mastectomies, including 67 bilateral mastectomies as first breast cancer surgery. Among those patients with retained breast tissue, the contralateral breast cancer rate was 25.3% at 5 years. Among 186 invasive tumors, 72.1% were stages I to II, 48.9% were node negative, and the most common subtypes were hormone receptor-positive/HER2-negative (40.9%) and hormone receptor positive/HER2 positive (34.4%). At a median follow-up of 69.9 months (interquartile range = 32.6-125.9), invasive hormone receptor-positive/HER2-negative disease had the highest recurrence risk among the subtypes (5-year recurrence-free survival = 61.1%, P = .001). Among those who received radiation therapy (n = 79), the 5-year radiation-induced sarcoma rate was 4.8%. CONCLUSION: We observed high rates of ductal carcinoma in situ, hormone receptor-positive, and HER2-positive breast cancers, with a worse outcome in the hormone receptor-positive/HER2-negative luminal tumors, despite appropriate treatment. Confirmation of these findings in further studies could have implications for breast cancer care in those with Li-Fraumeni syndrome.

ABSTRACT

PURPOSE: Genetic cancer risk assessment (GCRA) provides pathogenic variant (PV) carriers with the invaluable opportunity to undertake timely cancer risk-reducing (RR) measures and initiate cascade testing (CT). This study describes the uptake of these strategies and the related barriers among breast cancer-associated germline PV carriers in Mexico. METHODS: Carriers who were at least 6 months after disclosure of genetic test results at two GCRA referral centers were invited to answer a survey assessing sociodemographic characteristics, awareness of their carrier status and its implications, uptake of RR measures according to international guidelines by PV, CT initiation, and associated challenges. RESULTS: Of the eligible carriers, 246/384 (64%) answered the survey (median age: 44 years). Most were female (88%), married/in domestic partnership (66%), and had personal breast/ovarian cancer history (61%). PVs included BRCA1/2 (75%), CHEK2 (10%), PALB2 (5%), ATM (5%), NF1 (2%), RAD51C (2%), PTEN (1%), and TP53 (1%). Most (87%) participants were aware of their carrier status. When recommended, 37% underwent RR bilateral mastectomy, 48% RR oophorectomy, 70% annual mammogram, and 20% breast magnetic resonance imaging. Challenges hindering the uptake of RR measures included financial limitations (67%), lack of recommendation by their physician (35%), and fear (24%). Nearly all (98%) claimed sharing their results with their relatives. CT was initiated in 63% of families and was associated with carriers being married/in domestic partnership (P = .04) and believing GCRA was useful (P < .001). CONCLUSION: Despite the resource-constrained setting, relevant rates of RR measures and CT were observed. Targeted interventions to reduce out-of-pocket expenses and improve patient-physician communication and patients' understanding on carrier status are warranted to enhance the overall benefit of GCRA and ultimately improve the provision of patient-centered care to both carriers and their at-risk relatives.

ABSTRACT

Objective: To assess the impact of intravascular laser irradiation of blood (ILIB) on the primitive carotid artery (PCA) hemodynamic variables, specifically blood pressure (BP) and heart rate (HR), in mastectomized patients undergoing hormone blocker treatments. Materials and methods: This study is a controlled, experimental, and randomized clinical trial. Patients were allocated into two groups: the experimental group (G1)-patients who received ILIB therapy using a 660 nm laser targeted at the PCA, and the control group (G2)-patients who did not receive ILIB therapy. Clinical research was conducted weekly, with measurements of systolic blood pressure (SBP), diastolic blood pressure (DBP), and HR. The Mann-Whitney U test for independent samples was used, with a significance level of α = 0.05. Results: Systemic photobiomodulation on the PCA did not demonstrate a statistically significant difference in relation to SBP and DBP. However, for HR, the p-value was <0.05, indicating a significant difference between G1 and G2. The initial mean p > decreased from 142.3 to 116.4 mmHg in G1, and from 130.4 to 119.8 mmHg in G2. The DBP varied from 78.8 to 72.8 mmHg in G1, and from 79.1 to 74.2 mmHg in G2. A statistically significant difference was observed in HR, decreasing from 81.3 to 62.06 bpm in G1, and changing minimally from 74.1 to 75.1 bpm in G2. A considerable reduction was present in the timing of application. Conclusions: ILIB therapy applied to the PCA induces a reduction in BP and, more notably, HR in mastectomized women using the tamoxifen or aromatase inhibitors.

ABSTRACT

PURPOSE: This review aimed to identify, characterize, map, and summarize existing knowledge about the relationship of perceived body image with the quality of life (QoL) of women who have undergone surgical treatment for breast cancer. METHODS: A scoping review was conducted following the PRISMA-ScR guidelines. PubMed, PsycINFO and Scopus databases were searched, and articles published until August 2022 were included. RESULTS: The search resulted in 796 records, and 51 articles were included for analysis. A significant negative impact on body image perception and QoL after surgical treatment for breast cancer was found in the majority of studies. Sociodemographic variables such as age, education, socioeconomic status, unstable attachment styles and time after the surgery may have an effect on a worsening of the overall body image and QoL score of women. It was found that there was greater dissatisfaction with body image in women who underwent mastectomy compared to those who underwent conservative surgery. CONCLUSION: Evidence has shown that breast cancer surgery affects the perceived body image and QoL of patients worldwide. Age, education, socioeconomic status, and the type of surgery are potential factors influencing these outcomes. It is worth noting that the review encompassed articles from various countries, reflecting a significant cultural diversity among the studied populations. However, most of these articles did not delve into an analysis of these cultural disparities. This review also indicated insufficient details regarding the assessment instruments used to assess perceived body image.

ABSTRACT

This study evaluated the usability of conventional templates based on the new contour guidelines of the European Society of Radiation and Oncology and Advisory Committee in Radiation Oncology Practice (ESTRO-ACROP) for treatment plans of postmastectomy radiotherapy after immediate implant-based reconstruction. Intensity-modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT) plans generated with two different treatment planning systems (TPSs, Eclipse and Monaco) were examined. Six computed tomography scans of patients aged 35-54 years were retrospectively analysed who had undergone mastectomy and breast reconstruction using silicone implants after being diagnosed with left breast cancer. Six radiation oncologists participated in this study, and each of them contoured the target volume of one left breast using conventional contour (CTV-CONV) and new contour (CTV-ESTRO) methods. This study showed that compared with CTV-CONV, using CTV-ESTRO with objectives and cost functions similar to those of TPSs worsened the target volume coverage and increased the total number of monitor units. Considering the organs at risk, CTV-ESTRO tended to increase the mean dose delivered to the contralateral lung. It is concluded that the approach used for the new ESTRO-ACROP contour method cannot be applied in a manner similar to that for the conventional breast contour method, implying that the new ESTRO-ACROP contour method may require more time for improving plans for a given treatment.

ABSTRACT

PURPOSE: The Re-irradiation and the Breast Cancer Working Groups of the Italian Association of Radiotherapy and Clinical Oncology (AIRO) conducted a survey to provide an overview of the policies for breast cancer (BC) re-irradiation (re-RT) among the Italian radiotherapy (RT) centers. METHODS: In October 2021, 183 RT centers were invited to answer a survey: after an initial section about general aspects, the questionnaire focused on radiation oncologists' (ROs) attitude toward re-RT in three different scenarios: ipsilateral breast tumor recurrence (IBTR) treated with second conservative surgery, IBTR treated with mastectomy and inoperable IBTR. Surveyed ROs were also asked to express their interest in being involved in a prospective trials. RESULTS: Seventy-seven/183 (42.0%) centers answered the Survey, only one RO per center was requested to answer. In particular, 86.5% ROs declared to have performed "curative" re-RT for IBTR during the previous two years (2019-2020): 76.7% respondents administered re-RT after second BCS, 50.9% after mastectomy, and 48.1% for inoperable IBTR. Re-RT practice varied widely among centers in terms of treatment volumes, dose and fractionation schedules, techniques and dose-volume constraints for organs at risks (OARs). Forty-six participants (59.7%) expressed their interest in participating in a prospective study investigating BC re-RT. CONCLUSIONS: About one out of three RT centers in Italy delivered re-RT for IBTR. Nevertheless, practice of re-RT varied widely among centers highlighting the needs for prospective studies to improve knowledge in this field.
