- Cancer is a highly proliferative disease, which is caused due to the loss of regulation of cell cycle and apoptosis, DNA damage, faulty repair system etc. The cancer microenvironment plays a pivotal role in disease progression as they contain different types of innate and adaptive immune cells. The most important molecules that establish a correlation between inflammation, innate immunity, adaptive immunity, and cancer are the molecules released by inflammatory cells in cancer microenvironment. These molecules secreted by the immune cells, which might activate a pro-tumorigenic and anti-tumorigenic response in cancer. In inflammatory microenvironment, the equilibrium state of immunosuppressive and immunostimulatory signals are important in tumor suppression. The immunotherapeutic approaches could be more effective in cancer treatment. However, advancement in immunobiology and cancer are improving the prospects of immunotherapy alone and/or in combination with the conventional therapies. Thus, the review attempts to highlight a promising and futuristic immunotherapeutic approach in combination with conventional treatment modalities.

- Breast cancer consists of various subtypes like Her2+, ER/PR+Her2-, ER/PR+Her2+, TNBCs (Triple-Negative Breast Cancers), TPBCs (Triple-Positive Breast Cancers), etc., according to hormonal receptors and Her2 profile. Among these, TNBCs have limited therapeutic interventions, due to lack of receptors for ER, PR and Her2. Apart from BRCA1 and BRCA2, there are certain tumor suppressors and/or oncogenes (PML and RB1) influencing breast cancer, but the precise implication of these genes and their correlation is still not clearly understood. These genes play pivotal role in cell cycle regulation, proliferation, differentiation, survival, and apoptosis. Thus, we sought to identify the role of PML and RB1, and their correlation in breast cancer especially in TNBCs. Data demonstrated that 17% were TNBCs, interestingly among these cases, 72% showed remarkable upregulation of PML and downregulation of RB1; whereas 14% cases showed downregulation of PML and RB1, and 14% cases showed loss of expression of PML and RB1. To further validate our results, we included the data from METABRICS and TCGA datasets. Interestingly, our data showed good concordance with METABRICS and TCGA data showing upregulation of PML and downregulation of RB1 in TNBCs. In addition, we also checked the survivability effect of PML and RB1 through Kaplan-Meier plotter and observed that upregulation of PML and downregulation of RB1 decreases recurrence-free survivability in TNBC cases. Overall, the data suggests a plausible role of PML and RB1 genes in breast cancer patients particularly in TNBCs, where treatment options are limited compared to the other subtypes of breast cancer cases.

- The advent of immune-checkpoint inhibitors (ICI) in modern oncology has significantly improved survival in several cancer settings. A subgroup of women with breast cancer (BC) has immunogenic infiltration of lymphocytes with expression of programmed death-ligand 1 (PD-L1). These patients may potentially benefit from ICI targeting the programmed death 1 (PD-1)/PD-L1 signaling axis. The use of tumor-infiltrating lymphocytes (TILs) as predictive and prognostic biomarkers has been under intense examination. Emerging data suggest that TILs are associated with response to both cytotoxic treatments and immunotherapy, particularly for patients with triple-negative BC. In this review from The International Immuno-Oncology Biomarker Working Group, we discuss (a) the biological understanding of TILs, (b) their analytical and clinical validity and efforts toward the clinical utility in BC, and (c) the current status of PD-L1 and TIL testing across different continents, including experiences from low-to-middle-income countries, incorporating also the view of a patient advocate. This information will help set the stage for future approaches to optimize the understanding and clinical utilization of TIL analysis in patients with BC.

- The influence of the naturally occurring population of microbes on various human diseases has been a topic of much recent interest. Not surprisingly, continuously growing attention is devoted to the existence of a gut brain axis, where the microbiota present in the gut can affect the nervous system through the release of metabolites, stimulation of the immune system, changing the permeability of the blood-brain barrier or activating the vagus nerves. Many of the methods that stimulate the nervous system can also lead to the development of cancer by manipulating pathways associated with the hallmarks of cancer. Moreover, neurogenesis or the creation of new nervous tissue, is associated with the development and progression of cancer in a similar manner as the blood and lymphatic systems. Finally, microbes can secrete neurotransmitters, which can stimulate cancer growth and development. In this review we discuss the latest evidence that support the importance of microbiota and peripheral nerves in cancer development and dissemination.
