A Representative Clinical Course of Progression, with Molecular Insights, of Hormone Receptor-Positive, HER2-Negative Bone Metastatic Breast Cancer.

Despite treatment advances, breast cancer remains a leading cause of death of women in the United States, mostly due to metastatic disease. Bone is a preferential site for breast cancer metastasis, and most metastatic breast cancer patients experience bone involvement at the time of death. The majority of patients with bone metastatic breast cancer are first diagnosed with and treated for early-stage disease, and from development of early-stage breast cancer to the recurrence of cancer in the bones, up to 30 years may elapse. Throughout this timeframe, a typical patient undergoes many treatments that have effects on the bone microenvironment. Therefore, this review explores the clinical course of a representative patient with hormone receptor-positive bone metastatic breast cancer, examining key treatment options at each stage and their effects on preventing and treating bone metastases.

Treatments for alopecia areata: A systematic review and network meta-analysis.

Existing guidelines form no consensus for alopecia areata (AA) treatment due to the absence of a universal standard treatment and arbitrary selection of reference arms in randomized control trials (RCTs). The aim is to identify the best treatment and to rank treatments using systematic review and network meta-analysis. Data were extracted by the two investigators independently. Odds ratio (OR) of treatment success rate was pooled using the frequentist weighted least squares approach to random-model network meta-analysis. RCTs providing data of treatment success rate from PubMed, EMBASE, Web of Science, and manual search were included. About 54 RCTs consisting of 49 treatments and 3149 patients were included. Pentoxifylline plus topical corticosteroids had the highest treatment success rate compared with "no treatment," followed by pentoxifylline alone, topical calcipotriol plus narrowband ultraviolet radiation B phototherapy, topical calcipotriol, intralesional corticosteroids, systemic corticosteroids, minoxidil plus topical corticosteroids, topical bimatoprost, psoralen ultraviolet radiation A phototherapy, and tofacitinib. Even with the network meta-analysis, the best treatment because of independent loops and wide confidence intervals could not be identified. Treatment options above may be reasonable strategies, but further comparison is required.

SWI/SNF Complexes in Ovarian Cancer: Mechanistic Insights and Therapeutic Implications.

Ovarian cancer remains the most lethal gynecologic malignancy in the developed world. Despite the unprecedented progress in understanding the genetics of ovarian cancer, cures remain elusive due to a lack of insight into the mechanisms that can be targeted to develop new therapies. SWI/SNF chromatin remodeling complexes are genetically altered in approximately 20% of all human cancers. SWI/SNF alterations vary in different histologic subtypes of ovarian cancer, with ARID1A mutation occurring in approximately 50% of ovarian clear cell carcinomas. Given the complexity and prevalence of SWI/SNF alterations, ovarian cancer represents a paradigm for investigating the molecular basis and exploring therapeutic strategies for SWI/SNF alterations. This review discusses the recent progress in understanding SWI/SNF alterations in ovarian cancer and specifically focuses on: (i) ARID1A mutation in endometriosis-associated clear cell and endometrioid histologic subtypes of ovarian cancer; (ii) SMARCA4 mutation in small cell carcinoma of the ovary, hypercalcemic type; and (iii) amplification/upregulation of CARM1, a regulator of BAF155, in high-grade serous ovarian cancer. Understanding the molecular underpinning of SWI/SNF alterations in different histologic subtypes of ovarian cancer will provide mechanistic insight into how these alterations contribute to ovarian cancer. Finally, the review discusses how these newly gained insights can be leveraged to develop urgently needed therapeutic strategies in a personalized manner.
