Management of -associated breast cancer patients in low and middle-income countries: a review.

Breast cancer poses a significant global health challenge, with higher incidence rates in developed countries. However, low- and middle-income countries (LMICs) suffer from higher mortality rates due to various factors, including limited screening programs, delayed diagnosis and inadequate access to healthcare and advanced treatments. Approximately 5%-10% of breast cancer cases stem from germline mutations in -1/2 genes.

Surgical Tumor Resection Deregulates Hallmarks of Cancer in Resected Tissue and the Surrounding Microenvironment.

Unlabelled: Surgery exposes tumor tissue to severe hypoxia and mechanical stress leading to rapid gene expression changes in the tumor and its microenvironment, which remain poorly characterized. We biopsied tumor and adjacent normal tissues from patients with breast (n = 81) and head/neck squamous cancers (HNSC; n = 10) at the beginning (A), during (B), and end of surgery (C). Tumor/normal RNA from 46/81 patients with breast cancer was subjected to mRNA-Seq using Illumina short-read technology, and from nine patients with HNSC to whole-transcriptome microarray with Illumina BeadArray.

Synchronous and Metachronous Breast and Ovarian Cancers: Experience from a Single Tertiary Care Cancer Centre in India.

Women with either breast cancer (BC) or ovarian cancer (OC) have a 1.5-2 times higher risk of developing the other. Discerning discrete primaries versus metastases from either can be challenging.

Retrospective audit of the yield of internal mammary lymph node dissection and literature review in the management of breast cancer.

Background: Treatment of lymph node basins is prognostic and therapeutic for axillary lymph nodes (ALN) as well as internal mammary lymph nodes (IMLNs) in breast cancer. IMLNs can be the first echelon node for the inner/central quadrants of the breast. We evaluated the yield of IMLN dissection (IMLND) mainly in patients with inner and central tumors.

Validation of PREDICT Version 2.2 in a Retrospective Cohort of Indian Women With Operable Breast Cancer.

Purpose: Online prediction models that use known prognostic factors in breast cancer (BC) are routinely used to assist in decisions for adjuvant therapy. PREDICT Version 2.2 (P2.

Effectiveness of a Decision Aid Plus Standard Care in Surgical Management Among Patients With Early Breast Cancer: A Randomized Clinical Trial.

Importance: Patients with early breast cancer must choose between undergoing breast conservation surgery or mastectomy. This decision is often difficult as there are trade-offs between breast conservation and adverse effects, and women with higher decisional conflict have a harder time choosing the therapy that suits their preferences.

Objective: To study the impact of a decision aid with a patient preference assessment tool for surgical decision-making on patients' decisional conflict scale (DCS) score.

Post mastectomy pain syndrome at an Indian tertiary cancer centre and its impact on quality of life.

Background: Literature on Post mastectomy pain in the Indian population is scarce. Most literature is from the West. The current study aimed to identify the incidence of post-mastectomy pain syndrome (PMPS), pain severity, and its impact on quality of life in Indian patients.

Patient-Related Awareness of Impact of Cancer-Directed Therapy on Fertility in Young Women Diagnosed of Breast Cancer.

Nita S. Nair Chemotherapeutic agents used in the treatment of breast cancer (BC) adversely impact growing ovarian follicles and can induce permanent premature ovarian failure or reduce ovarian reserve in younger women. As treatments result in improved survival of BC patients, young survivors face quality of life (QOL) issues, including treatment-related infertility.

Accuracy of Intraoperative Frozen Section Analysis of Lymph Nodes in Women Undergoing Axillary Sampling for Treatment of Breast Cancer: Single Institution Audit.

Background: Axillary lymph node (LN) positivity is an important prognostic factor in breast cancer. Almost 30% clinically node negative (cN0) early breast cancers have positive nodes on pathology, wherein an axillary dissection is done as a second stage surgery. Intra operative frozen section (FS) potentially avoids redo surgery.

Long-term outcomes and prognostic factors in elderly patients with breast cancer: single-institutional experience.

Introduction: Despite advances in treatment, there is rising mortality in elderly patients with breast cancer. We aimed to conduct an audit of non-metastatic elderly breast cancer patients to understand the predictors of outcome.

Methods: Data collection was done from electronic medical records.

Effect of Peritumoral Infiltration of Local Anesthetic Before Surgery on Survival in Early Breast Cancer.

Purpose: Preventing metastases by using perioperative interventions has not been adequately explored. Local anesthesia blocks voltage-gated sodium channels and thereby prevents activation of prometastatic pathways. We conducted an open-label, multicenter randomized trial to test the impact of presurgical, peritumoral infiltration of local anesthesia on disease-free survival (DFS).

A Questionnaire Survey of Current Practice in the Management of Internal Mammary Lymph Nodes in Breast Cancer.

Nita S. Nair  Radiotherapy (RT) is an important modality in the management of breast cancers (BC). Large randomized trials have suggested that prophylactic regional nodal irradiation inclusive of internal mammary lymph nodes (IMLN) reduces BC-related mortality.

Determinants of pathological complete response to neoadjuvant chemotherapy in breast cancer: A single-institution experience.

Background: Neoadjuvant chemotherapy (NACT) is routinely used in all cases of locally advanced breast cancer and some cases of early breast cancer. We previously reported a pathological complete response (pCR) rate of 8.3%.

Outcomes of non-metastatic triple negative breast cancers: Real-world data from a large Indian cohort.

Background: Triple negative Breast tumor (TNBC) is an aggressive tumor with sparse data worldwide.

Methods: We analyzed non-metastatic TNBC from 2013 to 2019 for demographics, practice patterns, and survival by the Kaplan Meir method. Prognostic factors for OS and DFS were evaluated using Cox Proportional Hazard model estimator for univariate and multivariable analysis after checking for collinearity among the variables.

Prophylactic Use of Compression Sleeves Reduces the Incidence of Arm Swelling in Women at High Risk of Breast Cancer-Related Lymphedema: A Randomized Controlled Trial.

Purpose: To determine whether prophylactic use of compression sleeves prevents arm swelling in women who had undergone axillary lymph node dissection for breast cancer surgery.

Methods: Women (n = 307) were randomly assigned to either a compression or control group. In addition to usual postoperative care, the compression group received two compression sleeves to wear postoperatively until 3 months after completing adjuvant treatments.

Unique challenges and outcomes of young women with breast cancers from a tertiary care cancer centre in India.

Background: Young (≤40 years) breast cancers (YBC) are uncommon, inadequately represented in trials and have unique concerns and merit studying.

Methods: The YBC treated with a curative intent between 2015 and 2016 at our institute were analysed.

Results: There were 1228 patients with a median age of 36 (12-40) years; 38 (3.

Hyperechoic Lesions on Breast Ultrasound: All Things Bright and Beautiful?

Ultrasound (US) lexicon of the Breast Imaging Reporting and Data System (BI-RADS) defines an echogenic breast mass as a lesion that is hyperechoic in comparison with subcutaneous adipose tissue. However, at sonography, only 0.6 to 5.

Can We Avoid Axillary Lymph Node Dissection (ALND) in Patients with 1-2 Positive Sentinel/Low Axillary Lymph Nodes (SLN/LAS+) in the Indian Setting?

The ACOSOG Z0011 study, heralded as a "practice changing" trial, suggested that women with T1-2 breast cancer with 1-2 SLN+, undergoing breast conservation therapy, need not be offered further ALND. However, whether these results are applicable to all women in the Indian setting, it remains debatable. A retrospective audit of all cN0 operated from 2013 to 2018 was conducted.

Molecular Biology in the Breast Clinics-Current status and future perspectives.

Breast cancer is no longer considered a single disease, and with better understanding of cancer biology, its management has evolved over the years, into a complex individualized use of therapeutics based on variable expressions of predictive and prognostic factors. With the advent of molecular and genetic research, the complexity and diversity of breast cancer cells and their ability to survive and develop resistance to treatment strategies became more evident. At the same time, targeted therapies evolved, as specific targets were discovered such as HER2 receptor, and androgen receptor.

Randomized controlled trial comparing the efficacy of pectoral nerve block with general anesthesia alone in patients undergoing unilateral mastectomy.

This study was conducted to evaluate the efficacy of pectoral nerve block for post-operative analgesia in breast surgery patients. This double blinded, randomized controlled trial was conducted after Clinical Trials Registry-India registration. Sixty ASA grade I-II female patients undergoing unilateral modified radical mastectomy under general anesthesia, were recruited pre-operatively in two groups.

Access to HER2-targeted therapy at a tertiary care center in India: An evolution.

Background: In a previous retrospective audit from our institution we reported that patients had limited access to HER2-targeted therapy due to financial constraints. Subsequently, the advent of biosimilar versions of trastuzumab and philanthropic support has potentially changed this situation. Herein, we reanalyzed and reported access to HER2-targeted therapy in a more recent cohort of patients.

Survival outcomes with 12 weeks of adjuvant or neoadjuvant trastuzumab in breast cancer.

Background: There is limited access to 1 year of adjuvant trastuzumab in resource-constrained settings. Most randomized studies have failed to prove non-inferiority of shorter durations of adjuvant trastuzumab compared to 1 year However, shorter durations are often used when 1 year is not financially viable. We report the outcomes with 12 weeks of trastuzumab administered as part of curative-intent treatment.
