Endophytic fungi: A future prospect for breast cancer therapeutics and drug development

Globally, breast cancer is a primary contributor to cancer-related fatalities and illnesses among women. Consequently, there is a pressing need for safe and effective treatments for breast cancer. Bioactive compounds from endophytic fungi that live in symbiosis with medicinal plants have garnered significant interest in pharmaceutical research due to their extensive chemical composition and prospective medicinal attributes. This review underscores the potentiality of fungal endophytes as a promising resource for the development of innovative anticancer agents specifically tailored for breast cancer therapy. The diversity of endophytic fungi residing in medicinal plants, success stories of key endophytic bioactive metabolites tested against breast cancer and the current progress with regards to in vivo studies and clinical trials on endophytic fungal metabolites in breast cancer research forms the underlying theme of this article. A thorough compilation of putative anticancer compounds sourced from endophytic fungi that have demonstrated therapeutic potential against breast cancer, spanning the period from 1990 to 2022, has been presented. This review article also outlines the latest trends in endophyte-based drug discovery, including the use of artificial intelligence, machine learning, multi-omics approaches, and high-throughput strategies. The challenges and future prospects associated with fungal endophytes as substitutive sources for developing anticancer drugs targeting breast cancer are also being highlighted.

Rotter's Lymph Nodes-Do We Really Need to Remove During Axillary Clearance?

Surgical management of node positive breast cancer requires axillary dissection. Interpectoral nodes (IPNs) or Rotter's nodes removal is controversial as there is hardly any tissue in this region. IPNs involvement is rarely seen among breast cancer patients. Developing an effective protocol for surgical management of axilla is necessary for uniformity, to reduce the risk of regional recurrence and to avoid the morbidity of interpectoral lymphatic tissue clearance. This study aimed to evaluate the detection of lymph nodes in Rotter's region and positive metastasis rate of IPNs in patients with node positive breast cancer for analyzing the prognostic and therapeutic value of IPN excision during axillary clearance. Fifty-six patients undergoing axillary clearance, aged ≥ 18 years, were studied. Patients with recurrence or those who underwent neoadjuvant chemotherapy were excluded. Baseline investigations were done pre-operatively along with core needle biopsy, estrogen receptor (ER), progesterone receptor (PR), and Ki-67 status. Association between IPN status, age, and clinicopathological parameters were assessed by Kruskal Wallis and Chi-square test using R v 3.6.0. P value of ≤ 0.05 was considered statistically significant. Majority of patients had upper outer quadrant tumor location (22/56), and the most common histopathological type was invasive ductal carcinoma (46/56). IPNs were identified in 35.71% (20/56) of 56 patients, with metastasis prevalence of 27.27% (9/33 node positive patients). Patients having IPN metastasis had larger tumor size, later TNM classification, lower ER/PR, and higher Ki-67 positivity. Dissection of IPNs can be practiced routinely during axillary clearance and should be subjected to histopathological examination separately.
