Prevention and Treatment of Lymphedema in Breast Cancer.

Breast cancer related lymphedema (BCRL) affects many breast cancer survivors and drastically affects their quality of life. There are several surveillance methods for BCRL that are critical at early detection. Prevention of BCRL involves knowledge of alternatives to aggressive axillary surgery, avoidance of axillary surgery, and de-escalation of axillary surgery. There are also techniques to better delineate the anatomy in the axilla to avoid taking nodes that drain the upper extremity. A multidisciplinary approach with medical oncology and radiation oncology can also help avoid unnecessary surgery or radiation that can together strongly increase the risk of BCRL.

The Role of Surgery for Stage IV Breast Cancer.

Surgery for the management metastatic breast cancer has traditionally been considered a palliative procedure. However, some retrospective publications indicated that there may be a survival benefit to surgery in the presence of metastatic disease. Recent randomized trials will be reviewed for both management of the intact primary tumor in de novo breast cancer and systemic secondary metastases.

New concept in selecting blue dye injection site effect on clinical outcome of early-stage breast cancer patients: a retrospective cohort.

BACKGROUND: Clinico-anatomical review and pilot studies demonstrated that intraparenchymal injection at any site, even those not containing the index lesion, or periareolar injections should provide concordant outcomes to peritumoral injections. METHOD: This was a single-center retrospective cohort at King Chulalongkorn Memorial Hospital. The electronic medical records of patients were characterized into conventional and new injection concept groups. The inclusion criteria were patients who had either a mastectomy or BCS along with SLNB. We excluded patients who underwent ALND, received neoadjuvant therapy, or had non-invasive breast cancer. The primary outcome was the 5-year rate of breast cancer regional recurrence. Additionally, we reported on the re-operation rate, disease-free period, distant disease-free period, mortality rate, and recurrence rates both locoregional and systemic. Recurrences were identified through clinical assessments and imaging. SURGICAL TECHNIQUE: 3 ml of 1%isosulfan blue dye was injected, with the injection site varying according to the specific concept being applied. In cases of SSM and NSM following the new concept, the blue dye was injected at non-periareolar and non-peritumoral sites. After the injection, a 10-minute interval was observed without massaging the injection site. Following this interval, an incision was made to access the SLNs, which were subsequently identified, excised, and sent for either frozen section analysis or permanent section examination. RESULT: There were no significant differences in DFS, DDFS or BCSS between the two groups (p = 0.832, 0.712, 0.157). Although the re-operation rate in the NI group was approximately half that of the CI group, this difference was not statistically significant (p = 0.355). CONCLUSION: Our study suggests that tailoring isosulfan blue dye injection site based on operation type rather than tumor location is safe and effective approach for SLN localization in early-stage breast cancer. However, this study has limitations, including being a single-center study with low recurrence and death cases. Future studies should aim to increase the sample size and follow-up period.

Advances in breast cancer treatment: a systematic review of preoperative stereotactic body radiotherapy (SBRT) for breast cancer.

Breast conserving treatment typically involves surgical excision of tumor and adjuvant radiotherapy targeting the breast area or tumor bed. Accurately defining the tumor bed is challenging and lead to irradiation of greater volume of healthy tissues. Preoperative stereotactic body radiotherapy (SBRT) which target tumor may solves that issues. We conducted a systematic literature review to evaluates the early toxicity and cosmetic outcomes of this promising treatment approach. Secondary we reviewed pathological complete response (pCR) rates, late toxicity, patient selection criteria and radiotherapy protocols. We retrieved literature from PubMed, Scopus, Web of Science, Cochrane, ScienceDirect, and ClinicalTrials.gov. The study adhered to the PRISMA 2020 guidelines. Ten prospective clinical trials (7 phase II, 3 phase I), encompassing 188 patients (aged 18-75 years, cT1-T3 cN0-N3 cM0, primarily with ER/PgR-positive, HER2-negative status,), were analyzed. Median follow-up was 15 months (range 3-30). Treatment involved single-fraction SBRT (15-21Gy) in five studies and fractionated (19.5-31.5Gy in 3 fractions) in the rest. Time interval from SBRT to surgery was 9.5 weeks (range 1-28). Acute and late G2 toxicity occurred in 0-17% and 0-19% of patients, respectively, G3 toxicity was rarely observed. The cosmetic outcome was excellent in 85-100%, fair in 0-10% and poor in only 1 patient. pCR varied, showing higher rates (up to 42%) with longer intervals between SBRT and surgery and when combined with neoadjuvant systemic therapy (up to 90%). Preoperative SBRT significantly reduce overall treatment time, enabling to minimalize volumes. Early results indicate excellent cosmetic effects and low toxicity.

Social participation of women with breast cancer compared to the general population 5 years after primary surgery-what role do medical data and cancer-related complaints play?

PURPOSE: This study analyzes levels of social participation in patients with breast cancer on average 5 years following primary surgery as compared to women in the general population. In addition, the role of breast cancer-related complaints and medical data as possible influencing factors on levels of patients' social participation is investigated. METHODS: A total of n = 454 patients after primary surgery (t0) were recruited for a third follow-up study, and n = 372 completed this survey (t3), corresponding to a response rate of 82.2%. For measuring breast cancer-related complaints, participants completed a written questionnaire. Social participation was measured by a questionnaire on different leisure activities that was taken from the Socio-Economic Panel Study. Medical information was extracted from medical reports at t0. A principal component analysis was carried out to identify different dimensions of social participation. Chi2-tests and logistic regression analyses were applied to analyze social participation as compared to the general population and the role of possible medical and diagnosis-related influencing factors thereby. RESULTS: Compared to the general population, patients show lower levels of social participation in the domains "socio-cultural participation" and "participation in institutions," while no significant differences for "social participation in the private sphere" and "social participation via social media" were found. Psychological symptoms, pain, and a history of mastectomy were most strongly associated with restrictions in social participation. CONCLUSIONS: Our study suggests that social withdrawal may happen due to disease-related symptoms, preventing some breast cancer patients from participating fully in society. Cancer-related follow-ups should address this issue and support patients' reintegration into society through appropriate therapeutic interventions.

Severe capsular contracture in a patient with a history of multiple malignancies - Hematoma or neoplasm recurrence?: A case report.

RATIONALE: Complications associated with breast implants pose a significant obstacle to improving the quality of life for patients undergoing implant-based breast reconstruction. Due to the intricate nature of their presentation, diagnosis often becomes challenging and perplexing. Herein, we present a case report detailing the diagnostic and therapeutic processes employed in managing implant-related complications in a patient with multiple malignancies who underwent immediate breast reconstruction following mastectomy. PATENT CONCERNS: The patient, a 48-year-old woman, presented with severe pain and hardening in her left breast. She had previously undergone nipple-sparing mastectomy followed by immediate implant-based breast reconstruction 3 years ago. DIAGNOSES: Upon admission, we suspected a simple diagnosis of capsular contracture. However, upon investigation, she had a medical history of colon cancer, breast cancer, and acute B-lymphoblastic leukemia. Furthermore, she recently experienced nipple hemorrhage. INTERVENTIONS: Considering her clinical manifestations, we postulated the possibility of tumor recurrence along with potential presence of breast implant-associated anaplastic large cell lymphoma. The situation took a new turn, as diagnostic imaging techniques including breast MRI, and ultrasound revealed indications of potential prosthesis rupture and periprosthetic infection. OUTCOMES: Ultimately, en bloc capsulectomy with implant removal was performed, revealing no evidence of implant rupture or infection but rather indicating delayed hematoma formation. LESSONS: An accurate diagnosis of complications associated with breast prosthesis reconstruction is crucial for effective treatment. The examination and treatment processes employed in this case offer valuable insights toward achieving a more precise diagnosis of prosthesis-related complications, particularly in patients with complex medical histories.

Efficacy of Ultrasound-Guided Intercostal Nerve Block on Pain Management and Physiological Outcomes in Breast Cancer Mastectomy: A retrospective study.

To evaluate the efficacy of ultrasound-guided intercostal nerve block in managing pain and physiological responses in patients undergoing radical mastectomy for breast cancer. A retrospective study analyzed 120 patients scheduled to undergo radical mastectomy in our hospital between January 2022 and December 2023. Depending on the type of anesthesia received, participants were assigned to the experimental group (60 patients) to receive ultrasound-guided intercostal nerve block and intravenous general anesthesia, or the control group (60 patients) to receive intravenous general anesthesia only. Both groups will utilize patient-controlled intravenous analgesia (PCIA) postoperatively. We will monitor and compare hemodynamic parameters, SpO2, and bispectral index (BIS) at multiple time points, and assess postoperative pain, inflammatory markers, PCIA utilization, and adverse reaction incidence. Comparative analysis showed distinct trends in heart rate, mean arterial pressure (MAP), BIS, and SpO2 across various surgical stages between groups. Notably, MAP values were consistently higher and less variable in the experimental group during surgery (P < .05). Pain assessments at 4, 12, and 24 hours postoperatively in both quiet and coughing states revealed significantly milder pain in the experimental group (P < .05). Preoperative inflammatory markers (PGE2, TNF-α, IL-6, MCP-1) were similar between groups; however, 24 hours post-surgery, the experimental group showed significantly lower levels of PGE2, IL-6, and MCP-1 (P < .05). Sufentanil consumption during surgery and PCIA use were notably lower in the experimental group (P < .05). The experimental group also experienced fewer anesthesia-related adverse reactions (8.33%) compared to the control group (25.00%) (P < .05). Ultrasound-guided intercostal nerve block significantly improves hemodynamic stability, reduces postoperative inflammatory markers, lowers the need for sufentanil, and minimizes adverse reactions in patients undergoing radical mastectomy for breast cancer.

Oncoplastic Breast-Conserving Surgery in African Women: A Systematic Review.

PURPOSE: Breast cancer is the most frequently diagnosed cancer in women worldwide. Surgery is a major treatment modality for breast cancer, and over the years, breast-conserving surgeries with breast radiation have shown similar outcomes with mastectomy. Not much is known about the frequency and outcome of breast-conserving surgery in Africa. This systematic review provides a comprehensive summary of the evidence evaluating cosmetic and oncologic outcomes after oncoplastic breast-conserving surgery (OBCS) for breast cancer in African women. METHODS: This review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases were systematically searched for studies on African women undergoing OBCS. The oncologic and cosmetic outcomes, as well as the localization and reconstruction techniques, were evaluated. Descriptive statistics were used to summarize the frequency and proportions of the extracted variables. RESULTS: The literature search yielded 266 articles but only 26 of these were included in the review. Majority of the studies were from Egypt and South Africa. These studies collectively evaluated 1,896 patients with a mean age of 48.2 years and a mean follow-up period of 36.9 months. The most common histopathology was T2 (71.4%) invasive ductal carcinoma. Hook wire localization was the most common technique used for nonpalpable lesions in 85.3% of patients. Of the studies reporting oncoplastic technique, the latissimus dorsi volume replacement technique was the most reported (15%). Most patients were satisfied with their cosmetic outcome. Seroma was the most common postoperative complication (44.6%). Among studies that reported oncologic outcome data, the crude overall survival and disease-free survival were 93.1% and 89.4%, respectively. CONCLUSION: This systematic review revealed that the outcome of OBCS in African women compares with that in developed countries.

Clinical efficacy and safety of ultrasound-guided high-intensity focused ultrasound for breast fibroadenoma: a systematic review and meta-analysis.

OBJECTIVE: The purpose of this systematic review and meta-analysis was to assess the clinical efficacy and safety of ultrasound (US)-guided high intensity focused ultrasound (HIFU) in the treatment of breast fibroadenoma in different studies. METHODS: Studies evaluating the efficacy and safety of US-guided HIFU in the treatment of histologically-proven FA with follow-up outcomes of more than 3 months were searched through MEDLINE/PubMed databases. Volume reduction rate (VRR) and side effects were extracted and compared for further analysis. RESULTS: Of 29 identified articles, 10 studies involving 385 women and more than 545 FAs met the inclusion criteria. The mean VRR at 6 months and 12 months after HIFU was 52.00% and 72.00%. In terms of intraoperative safety, nine studies reported mild to moderate pain, with an average visual analogue scale (VAS) score ranging from 1.60 to 7.10. The most common postoperative side effect associated with HIFU was subcutaneous ecchymosis and less frequent were pain, erythema, and skin pigmentation, most of which disappeared within weeks. No serious side effects were observed. CONCLUSION: S-guided HIFU is an effective and safe noninvasive treatment for breast FA that does not cause serious side effects. Further studies are needed to explore crucial influencing factors of VRR.

Preoperative psychological factors influence analgesic consumption and self-reported pain intensity following breast cancer surgery.

BACKGROUND: Psychological factors such as anxiety and mood appear to influence acute postoperative pain; however, there is conflicting evidence on the relationship between preoperative psychological parameters and the severity of postoperative pain. In the context of the stressful setting of initial surgery for breast cancer, we conducted a prospective observational study of patients who were scheduled to undergo initial breast cancer surgery. METHODS: The objectives were to examine the potential associations between predefined preoperative psychological parameters and (i) Self-reported pain scores at discharge from the postoperative acute care unit, (ii) Cumulative perioperative opioid consumption at four hours postoperatively and (iii) Self-reported pain as measured during the first seven days after surgery. Patients completed the following questionnaires during the three hours prior to surgery: the Spielberger State Trait Anxiety Inventory (STAI State and Trait), the Pain Catastrophizing Scale (PCS), the Cohen Stress Questionnaire (CSQ), the Hospital Anxiety and Depression Scale (HADS A and D), and the short-form McGill Pain Questionnaire. Postoperative pain experience was assessed using patient self-reports of pain (SF Magill Pain questionnaire on discharge from the postanaesthesia care unit and a pain diary for seven days postoperatively) and records of analgesic consumption. RESULTS: Pre- to postoperative self-reported pain was significantly different with respect to the STAI State, Cohen score and PCS for both low and high values (p < 0.001), but only patients categorized as having low STAI Trait, HADS A, and HADS D values achieved significant differences (p < 0.001). A significant positive correlation was demonstrated between preoperative state anxiety (STAI) and the most severe pain reported during the first seven days postoperatively (r = 0.271, p = 0.013). Patients who were categorized preoperatively as having a "high value" for each of the psychological parameters studied (HADS A and D, STAI State and Trait and PCS) tended to have greater perioperative opioid consumption (up to four hours postoperatively); this trend was statistically significant for HADS D and HADS A only. Using a linear regression model, state anxiety was found to be a significant predictor of postoperative pain based on self-reports during the first seven postoperative days (standardized ß = 0.271, t = 2.286, p = 0.025). CONCLUSION: Preoperative state anxiety, in particular, is associated with the severity of postoperative pain experienced by women undergoing initial breast cancer surgery. Formal preoperative assessment of anxiety may be warranted in this setting with a view to optimize perioperative analgesia and wellbeing.

To Reconstruct or Not to Reconstruct: Piloting a Vietnamese and Arabic Breast Reconstruction Decision Aid in Australia.

Currently, there are no resources to support culturally and linguistically diverse (CALD) women with breast cancer to make decisions about undergoing breast reconstruction (BR). This study evaluated the usability and acceptability of decision aids (DAs) for Vietnamese- and Arabic-speaking women. This two-phase qualitative recruited Vietnamese- (Phase 1) and Arabic-speaking (Phase 2) adult (age ≥ 18 years) women who were diagnosed with breast cancer and could read Vietnamese/Arabic. Women participated in either think-aloud telephone interviews (Phase 1) or semi-structured telephone interviews (Phase 2) and provided feedback on the DA. Interviews were audio-recorded, translated, and transcribed from Vietnamese/Arabic to English, and inductive thematic analysis was undertaken. Additionally, Arabic-speaking women completed the Preparation for Decision Making (PrepDM) scale in Round 2. Twenty-five women were recruited in two phases (Phase 1: Vietnamese-speaking women, n = 14; Phase 2: Arabic-speaking, n = 11). Three themes were developed in Phase 1: (1) DA content and reception; (2) linguistic attributes and cultural appropriateness; and (3) factors that improve the DAs' impact. Three themes were developed in Phase 2: (1) varying perceptions of DA content; (2) linguistic and cultural suitability of information; and (3) impact of DA on decision making. Women from both phases identified areas for improvement: minimising the use of medical terminology, considering the cultural taboos associated with the word 'breast', and addressing remaining information gaps. Both language DAs were generally perceived as acceptable and useful in providing information about BR options and prompting women's reflections about the suitability of BR as part of their treatment. The mean PrepDM score for Arabic-speaking women in Round 2 was 4.8/5 (SD = 0.3). Further work is needed to ensure that culturally adapted DAs take into account the myriad of information needs and health literacy levels. The key role of healthcare professionals in shared decision making among CALD populations should also be considered.

Long-term Outcome After Helical Tomotherapy Following Breast Conserving Surgery for Ductal Carcinoma In Situ.

Background: This retrospective study aimed to investigate the outcomes and adverse events (AEs) associated with adjuvant radiotherapy with helical tomotherapy (hT) after breast-conserving surgery (BCS) for ductal carcinoma in situ (DCIS). Methods: Twenty-eight patients with DCIS underwent postoperative hT between 2011 and 2020. hT was chosen since it provided optimal target coverage and tolerable organ-at-risk doses to the lungs and heart when tangential 3-dimensional conformal radiotherapy (3D-CRT) was presumed to provide unfavorable dosimetry. The median total (single) dose was 50.4 Gy (1.8 Gy). The median time between BCS and the start of hT was 5 weeks (range, 4-38 weeks). Statistical analysis included local recurrence-free survival, overall survival (OS), and secondary cancer-free survival. AEs were classified according to the Common Toxicity Criteria for Adverse Events, version 5. Results: The patients' median age was 58 years. The median follow-up period was 61 months (range, 3-123 months). The 1-, 3-, and 5-year OS rates were 100% each. None of the patients developed secondary cancer, local recurrence, or invasive breast cancer during follow-up. The most common acute AEs were dermatitis (n = 27), fatigue (n = 4), hyperpigmentation (n = 3), and thrombocytopenia (n = 4). The late AE primarily included surgical scars (n = 7) and hyperpigmentation (n = 5). None of the patients experienced acute or late AEs > grade 3. The mean conformity and homogeneity indices were 0.9 (range, 0.86-0.96) and 0.056 (range, 0.05-0.06), respectively. Conclusion: hT after BCS for DCIS is a feasible and safe form of adjuvant radiotherapy for patients in whom 3D-CRT is contraindicated due to unfavorable dosimetry. During follow-up, there were no recurrences, invasive breast cancer diagnoses, or secondary cancers, while the adverse effects were mild.

Survival Outcomes of Breast-Conserving Surgery Versus Mastectomy in Locally Advanced Breast Cancer Following Neoadjuvant Chemotherapy: A Meta-Analysis.

BACKGROUND: Mastectomy (MT) and breast conservation surgery (BCS) are two common surgical options for the treatment of locally advanced breast cancer (LABC). Neoadjuvant chemotherapy (NACT) is frequently administered before surgery to shrink tumors and improve surgical outcomes. However, there is a lack of consensus on the optimal surgical approach after NACT and its impact on survival outcomes. OBJECTIVE: This meta-analysis aims to compare the survival outcomes between MT and BCS in patients treated with NACT. METHOD: A PRISMA selection was used to identify studies across electronic database such as PubMed, and Cochrane Library from inception until 11th July, 2023. A total of 10 comparative studies involving a total of 5018 patients were included. Among them, 2898 patients underwent MT while 2120 underwent BCS after receiving NACT. The outcomes assessed were the 5-year overall survival (OS) and 5-year disease-free survival (DFS). The data from the included studies were pooled, and odds ratios (OR) with 95% confidence intervals (CI) were calculated to evaluate the differences between MT and BCS in terms of survival outcomes. Prospero: CRD42024496831. RESULT: The meta-analysis revealed that patients who underwent MT after NACT had a higher 5-year OS compared to those who underwent BCS (OR 2.68, 95% CI [2.19-3.28; p < 0.00001]). Additionally, the 5-year DFS was significantly better for patients who underwent MT (OR 3.11, 95% CI [1.80-5.38; p < 0.0001]). CONCLUSION: MT after NACT may be associated with better 5-year OS and DFS compared to BCS.

Survival outcomes after breast cancer surgery among older women with early invasive breast cancer in England: population-based cohort study.

BACKGROUND: This study assessed the influence of age, co-morbidity and frailty on 5-year survival outcomes after breast conservation surgery (BCS) with radiotherapy (RT) versus mastectomy (with or without RT) in women with early invasive breast cancer. METHODS: Women aged over 50 years with early invasive breast cancer diagnosed in England (2014-2019) who had breast surgery were identified from Cancer Registry data. Survival estimates were calculated from a flexible parametric survival model. A competing risk approach was used for breast cancer-specific survival (BCSS). Standardized survival probabilities and cumulative incidence functions for breast cancer death were calculated for each treatment by age. RESULTS: Among 101 654 women, 72.2% received BCS + RT and 27.8% received mastectomy. Age, co-morbidity and frailty were associated with overall survival (OS), but only age and co-morbidity were associated with BCSS. Survival probabilities for OS were greater for BCS + RT (90.3%) versus mastectomy (87.0%), and the difference between treatments varied by age (50 years: 1.9% versus 80 years: 6.5%). Cumulative incidence functions for breast cancer death were higher after mastectomy (5.1%) versus BCS + RT (3.9%), but there was little change in the difference by age (50 years: 0.9% versus 80 years: 1.2%). The results highlight the change in baseline mortality risk by age for OS compared to the stable baseline for BCSS. CONCLUSION: For OS, the difference in survival probabilities for BCS + RT and mastectomy increased slightly with age. The difference in cumulative incidence functions for breast cancer death by surgery type was small regardless of age. Evidence on real-world survival outcomes among older populations with breast cancer is informative for treatment decision-making.

The impact of a breast cancer diagnosis on marital outcomes and factors associated with divorce and separation.

Objective: To analyze marital outcomes, divorce or separation, and its association with demographic, socioeconomic, and clinicopathological factors among breast cancer (BC) survivors after 2-years of diagnosis. Methods: We performed a retrospective analysis of marital status at baseline and at years 1 and 2 of follow-up of women aged ≥ 18 years diagnosed with invasive BC participating in the AMAZONA III (GBECAM0115) study. The BC diagnosis occurred between January 2016 and March 2018 at 23 institutions in Brazil. Results: Of the 2974 women enrolled in AMAZONA III, 599 were married or living under common law at baseline. Divorce or separation occurred in 35 (5.8%) patients at 2 years of follow-up. In the multivariate analysis, public health insurance coverage was associated with a higher risk of marital status change (8.25% vs. 2.79%, RR 3.09, 95% CI 1.39 - 7.03, p = 0.007). Women who underwent mastectomy, adenomastectomy or skin-sparing mastectomy were associated with a higher risk of divorce or separation (8.1% vs. 4.49%, RR 1.97, 95 CI 1.04 - 3.72, p = 0.0366) than those who underwent breast-conserving surgery. Conclusion: Women covered by the public health system and those who underwent mastectomy, adenomastectomy or skin-sparing mastectomy were associated with a higher risk of divorce or separation. This evidence further supports the idea that long-term marital stability is associated with a complex interplay between socioeconomic conditions and stressors, such as BC diagnosis and treatment. ClinicalTrials Registration: NCT02663973.

Comparison of minimal access and open breast surgery: a propensity score-matched study on postoperative immune function in breast cancer.

BACKGROUND: Minimal access breast surgery (MABS) is commonly employed in the management of breast cancer, but there is limited research on the postoperative immune function associated with MABS. OBJECTIVE: This study aimed to assess the postoperative immune function in breast patients who underwent MABS or conventional open breast surgery (COBS). METHODS: We retrospectively analyzed the medical records of 829 breast cancer patients treated with either MABS or COBS at a single hospital between January 2020 and June 2023. Among them, 116 matched pairs were obtained through 1:1 propensity score matching (PSM). Flow cytometry was used to measure the percentages of CD3+, CD4+, and CD8+ cells, as well as the CD4+/CD8+ ratio, on three different time points: preoperative day 1 (PreD1), postoperative day 1 (PostD1), and postoperative day 7 (PostD7). RESULTS: Both the MABS and COBS groups demonstrated a significant reduction in the percentages of CD3+, CD4+, and CD8+ cells, along with the CD4+/CD8+ ratio, from PreD1 to PostD1. Interestingly, the MABS group showed a reversal of these parameters, returning to preoperative levels by PostD7. Conversely, the COBS group showed an increase in these parameters from PostD1 to PostD7, but they still remained significantly lower than preoperative levels at PostD7. CONCLUSION: MABS treatment may result in reduced postoperative immune suppression and faster recovery of preoperative immune function compared to COBS in patients.

Core concomitant symptoms reported by the patients with breast cancer in postoperative endocrine treatment and the demand for acupuncture therapy： a network-based cross-sectional study. / ä¹³è ºç™Œæœ¯åŽå† åˆ†æ³Œæ²»ç–—æ‚£è€ æŠ¥å‘Šçš„æ ¸å¿ƒä¼´éšç—‡çŠ¶åŠå¯¹é’ˆç¸æ²»ç–—çš„éœ€æ±‚ï¼šä¸€é¡¹åŸºäºŽç½‘ç»œçš„æ¨ªæ–­é¢ç ”ç©¶.

OBJECTIVES: To investigate the most common concomitant symptoms and the urgent demand of solution in the breast cancer patients undergoing postoperative endocrine treatment, as well as the acceptance and expectation of acupuncture in the patients so as to provide the scientific data for promoting the application of acupuncture in the breast cancer patients. METHODS: Breast cancer patients treated in Tianjin Medical University Cancer Institute and Hospital from January 2022 to March 2023 were randomly selected as the subjects. Using "questionnaire star" website, the questionnaire was conducted to investigate the relevant concomitant symptoms of the patients in postoperative endocrine treatment and the questions related to acupuncture treatment. RESULTS: In this study, 229 questionnaires were distributed and 211 valid ones were collected, with the response rate of 92.1%. Among these patients, the first three common symptoms were sleep disorders (157 cases, 74.4%), hot flashes (138 cases, 65.4%) and joint / muscle pain (118 cases, 55.9%)；the top three symptoms to be solved the most urgently were sleep disorders (131 cases, 62.1%), joint / muscle pain (62 cases, 29.4%) and hot flashes (45 cases, 21.3%). 79.1% of the patients (167 cases) were willing to receive acupuncture treatment because of the high expectations on its potential effect (93%). 20.9% of them (44 cases) refused acupuncture because they were worried not to be treated by the experienced physicians of TCM (52%) or afraid of needling feelings (48%). The average expectation value of acupuncture treatment was 4.02 points (5 points for the total score) among patients willing to receive acupuncture treatment. The main purposes of receiring acupuncture for the patients undergoing endocrine treatment were to strengthen the immune function (92%), reduce the adverse reactions (83%), and improve the physical condition (75%), et al. CONCLUSIONS: Sleep disorder is one of the most concerned symptoms in endocrine treatment for the patients after breast cancer surgery. The patients highly expect for acupuncture treatment even though some patients dislike the needling sensation. How to provide the acceptable and high-quality acupuncture services for cancer patients will be one of the major directions of acupuncture research in the future.

NGS mutational status on first diagnostic tissue, liquid biopsy and mastectomy in G2-G3 breast cancer.

Breast cancer is one of the more frequently diagnosed cancers leading to death in women, and, like other tumor types, it is heterogeneous in its immunophenotype. It harbors mutations that modify tumor aggressiveness, therapy responses, residual disease, drug resistance, and relapse rates in advanced stages. This study aims to assess the mutational status of G2 and G3 tumors using next-generation sequencing (NGS) on initial tissue biopsies, liquid biopsies, and mastectomy specimens. The histopathological (HP) diagnosis for the 32 selected cases was established via Hematoxylin-Eosin (HE) staining by two observers. For the immunohistochemical (IHC) testing of estrogen receptor (ER), progesterone receptor (PGR) and human epidermal growth factor receptor 2 (HER2), we used the Ventana BenchMark Ultra. Ki67 testing was conducted using Bond-III from Leica. For cases with a score of 2+, gene amplification was assessed by silver-enhanced in situ hybridization (ISH) (SISH; Inform HER2 Dual ISH) on Ventana BenchMark Ultra. NGS analysis was initially performed on biopsies and plasma, and later on mastectomy specimens. After automated deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) extraction, concentrations were measured using the Invitrogen Qubit system. Libraries were created using Oncomine systems, and sequencing and analysis were done with the Ion Torrent system. Most tumors were graded as G3 (19 cases), with Luminal A being the predominant molecular subtype, and a significant number displayed HER2∕HER2-low characteristics (24 out of 32 cases). The NGS assessment showed that phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit alpha (PIK3CA) mutations were the most frequent across all sample types. A significant limitation was the high number of invalid plasma tests due to pre-analytical handling errors or transport issues. Nonetheless, plasma testing (liquid biopsy) proved useful for monitoring tumor evolution and assessing residual disease.

Predictors of residual disease after breast conservation surgery for ductal carcinoma in situ: A retrospective study.

BACKGROUND: Breast-conserving therapy is the standard of care for ductal carcinoma in situ (DCIS). Debate on what constitutes a satisfactory margin persists. This study aimed to identify predictors of residual disease at re-excision. METHODS: This is a population-based retrospective cohort study of women with DCIS who underwent a lumpectomy between 2007 and 2017 in Manitoba, with close (≤2 mm) or positive margins that led to re-excision. RESULTS: The DCIS re-excision rate was 29.3% for 1001 patients. 63.2% of patients were found to have residual disease on re-excision. On univariable analysis, the size, margin status, number of positive margins, type of second surgery, and Van Nuys Prognostic Index score were associated with residual disease on re-excision. The size of DCIS and the number of positive margins remained statistically significant on multivariable analysis. CONCLUSIONS: Re-excision should be rationalized by considering the predictors of residual disease in conjunction with other factors.

Quality of life in patients treated with breast cancer surgery and adjuvant systemic therapy and/or adjuvant radiotherapy in Uruguay.

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.
