New Treatment

Breast cancer is a major health concern as it is the second leading cause of death from cancer. There are several well-known risk factors that contribute to breast cancer. Despite the various treatment options available, complete cure is still difficult due to heterogenicity of BC subtypes. As a result, identifying BC subtypes is critical for determining the optimal treatment approach. Over the last several years, new drugs targeting particular therapeutic targets have resulted in significant advances in the treatment of breast cancer. Nonetheless, resistance to treatment is the “major” issue, and a significant increase in survival rates has been the main focus for researchers. The purpose of this review article is to provide a broad overview of the molecular basis of drug resistance in breast cancer, as well as a detailed assessment of current treatment options, potential new treatment methods for drug-resistant breast cancer and repurposed drugs used for treatment. The possibility of non-cancer drugs being studied for breast cancer in the future, as well as the obstacles and bottlenecks of drug repurposing, is also highlighted. Finally, we go through present problems and future prospects in drug-resistant breast cancer therapy.

The Zika virus (ZIKV) infection is a major public health concern in Brazil and worldwide, being a rapidly spreading disease with possible severe complications for pregnant women and neonates. There is currently no preventative therapy or specific treatment available. Within this context, drug repositioning is a very promising approach for the discovery of new treatment compounds, since old drugs may become new ones. Therefore, this paper aims to perform a literature mini-review to identify promising compounds to combat this virus. The mechanism of action at the molecular level and the structure-activity relationship of prototypes are discussed. Among the candidates identified, we highlight sofosbuvir, chloroquine and suramin, which present a greater quantity of experimental data to draw on for our discussion. The current treatment is palliative; therefore, this study is of paramount importance in identifying drug candidates useful for combating ZIKV.

Resistance Rates

Brain tumors in adults may be infrequent when compared with other cancer etiologies, but they remain one of the deadliest with bleak survival rates. Current treatment modalities encompass surgical resection, chemotherapy, and radiotherapy. However, increasing resistance rates are being witnessed, and this has been attributed, in part, to cancer stem cells (CSCs). CSCs are a subpopulation of cancer cells that reside within the tumor bulk and have the capacity for self-renewal and can differentiate and proliferate into multiple cell lineages. Studying those CSCs enables an increasing understanding of carcinogenesis, and targeting CSCs may overcome existing treatment resistance. One approach to weaponize new drugs is to target these CSCs through drug repurposing which entails using drugs, which are Food and Drug Administration–approved and safe for one defined disease, for a new indication. This approach serves to save both time and money that would otherwise be spent in designing a totally new therapy. In this review, we will illustrate drug repurposing strategies that have been used in brain tumors and then further elaborate on how these approaches, specifically those that target the resident CSCs, can help take the field of drug repurposing to a new level.

ABSTRACTCarbapenem-resistantAcinetobacter baumannii(CRAB) is a perilous nosocomial pathogen causing substantial morbidity and mortality. Current treatment options for CRAB are limited and suffer from pharmacokinetic limitations, such as high toxicity and low plasma levels. As a result, CRAB is declared as the top priority pathogen by the World Health Organization for the investment in new drugs. This urgent need for new therapies, in combination with faster FDA approval process, accelerated new drug development and placed several drug candidates in the pipeline. This article reviews available information about the new drugs and other therapeutic options focusing on agents in clinical or late-stage preclinical studies for the treatment of CRAB, and it evaluates their expected benefits and potential shortcomings.

New Treatment

Melanoma of the skin is one of the most aggressive malignant neoplasms. Metastatic skin melanoma has an extremely poor clinical prognosis with a high mortality rate, accounting for 80% of all deaths from skin malignancies. The approaches to the treatment of metastatic skin melanoma have been dynamically developing over the past decade. New drugs and their combinations are becoming more affordable. In connection with the advances in molecular genetics and the development of new targeted drugs, treatment outcomes have significantly improved: first of all, overall survival and the time to progression of the disease, which has set new challenges for continuing research in this area. The development of new treatment options for patients with inoperable and/or metastatic melanoma with a mutation in the BRAFV600 gene is still in high demand. Emerging data from clinical and preclinical studies suggest that synergies can be observed between inhibitors of immune checkpoints and inhibitors of BRAF and MEK. Despite the fact that inhibitors of the BRAF signaling pathway have a high frequency of objective responses, in most cases their duration is short. Inhibitors of immune checkpoints provide a longer lasting effect, but the response rate is relatively low. Combining the two types of therapy can improve survival rates over the long term. This review demonstrates the results of phase III randomized trials that have allowed to determine the current standards in the treatment of metastatic skin melanoma. We also demonstrated our own experience of using a triple combination of targeted therapy with BRAF/MEK inhibitors in combination with PD-1 inhibitors.

Oral Cancer (OC) is a serious and growing problem which constitutes a huge burden on people in more and less economically developed countries alike. The scenario is clearly depicted from the increase in the expected number of new cases in the US diagnosed with OC from 49,670 people in 2016, to 49,750 cases in 2017. The situation is even more alarming in India, with 75,000 to 80,000 new cases being reported every year, thus making it the OC capital of the world. Leukoplakia, erythroplakia, oral lichen planus, oral submucous fibrosis, discoid lupus erythmatosus, hereditary disorders such as dyskeratosis congenital and epidermolisys bullosa are highlighted by WHO expert working group as the predisposing factors increasing the risk of OC. Consumption of tobacco and alcohol, genetic factors, and human papilloma virus are assigned as the factors contributing to the aetiology of OC. On the other hand, pathogenesis of OC involves not only apoptosis but also pain, inflammation and oxidative stress. Inspite of current treatment options (surgery, radiotherapy, and chemotherapy), OC is often associated with recurrence and formation of secondary primary tumours resulting in poor overall survival rates (∼50%). The intervention of nano technology-based drug delivery systems as therapeutics for cancers is often viewed as a cutting edge for technologists. Though ample literature on the usefulness of nano-coutured cancer therapeutics, rarely any product is in pipeline. Yet, despite all the hype about nanotechnology, there are few ongoing trials. This review discusses the current and future trends of nano-based drug delivery for the treatment of OC.

In many clinical studies published over the past 20 years, adolescents and young adults (AYA) with Philadelphia chromosome negative acute lymphoblastic leukemia (Ph− ALL) were considered as a rather homogeneous clinico-prognostic group of patients suitable to receive intensive pediatric-like regimens with an improved outcome compared with the use of traditional adult ALL protocols. The AYA group was defined in most studies by an age range of 18–40 years, with some exceptions (up to 45 years). The experience collected in pediatric ALL with the study of post-induction minimal residual disease (MRD) was rapidly duplicated in AYA ALL, making MRD a widely accepted key factor for risk stratification and risk-oriented therapy with or without allogeneic stem cell transplantation and experimental new drugs for patients with MRD detectable after highly intensive chemotherapy. This combined strategy has resulted in long-term survival rates of AYA patients of 60–80%. The present review examines the evidence for MRD-guided therapies in AYA’s Ph− ALL, provides a critical appraisal of current treatment pitfalls and illustrates the ways of achieving further therapeutic improvement according to the massive knowledge recently generated in the field of ALL biology and MRD/risk/subset-specific therapy

Ovarian Function Suppression

The optimal endocrine therapy for premenopausal women with early and advanced breast cancer still remains an important and controversial issue. For over 30 years, tamoxifen has been the gold standard in the adjuvant setting. New therapeutic options, such as the addition of ovarian function suppression to oral endocrine therapy (either tamoxifen or aromatase inhibitors), can improve outcomes over tamoxifen alone in well-selected patients. Treatment duration has also been revisited, and extended therapy is becoming a new standard of care, especially in high-risk patients. Endocrine therapy for advanced disease still represents a challenge and a research priority. New drugs and combinations able to overcome endocrine resistance are at the horizon, and their role in premenopausal women should be better elucidated. Side effects and quality of life (including family planning considerations) play an important role in treatment selection and in the patients' treatment adherence and should always be discussed before start of treatment. The paper will specifically focus on how to integrate all new treatment options in the current armamentarium of endocrine therapy of premenopausal women, with the aim of best fine-tuning treatment selections according to the individual risk/benefit evaluation.
