Colorectal cancer (CRC) is a commonly diagnosed malignancy. Although chemotherapy remains the backbone of treatment, the landscape of treating metastatic CRC (mCRC) is changing with the understanding of its heterogeneity and molecular blueprint. Bomedemstat concentration Colon cancer sidedness has proven to hold prognostic implications, with right-sided tumors having higher incidence of BRAF and KRAS mutations and being microsatellite instability-high (MSI-H); overall, they have a worse prognosis compared with left sided-tumors. Results of molecular research have demonstrated the need to profile each mCRC patient for RAS and BRAF mutations, MSI-H status, HER2 amplifications, and NTRK fusions. Ongoing clinical trials using targeted agents aim to further improve survival outcomes. We emphasize the epidemiology, knowledge of primary tumor location, and mutational landscape of mCRC, as well as novel treatment options for patients harboring unique subtypes of these characteristics.Breast metastasis from extramammary malignancy is rare, with a reported incidence rate of 0.4% to 1.3% in the published literature. The primary malignancies that most commonly metastasize to the breast are leukemia, lymphoma, and malignant melanoma. Here, we report a very rare case of metastatic EGFR-mutated non-small cell lung cancer (NSCLC) in the breast detected by screening mammography. The patient had initially been diagnosed with a clinical stage IIIA NSCLC and had been treated with neoadjuvant chemoradiation followed by curative-intent surgery. Several interesting aspects of the case, along with a discussion of evolving adjuvant and frontline metastatic management options in EGFR-mutated NSCLC, will be presented.Judd W. Moul, MD, discusses the effects that COVID-19 may have on the outcomes for patients with cancer in the United States and throughout the world.The results of 2 studies showed no association between delayed radical prostatectomy(RP) and adverse oncological outcomes, supporting current recommendations of urologic societies for surgical treatment of patients with intermediate- and high-risk prostate cancer during the coronavirus disease 2019 (COVID-19)pandemic.During the height of the coronavirus disease 2019(COVID-19) pandemic, many health care facilities needed to focus on screening for and treating patients with known or suspected COVID-19. This resulted in the diversion of health care workers and resources.Coronavirus disease 2019 (COVID-19) accounts for over 180,000 deaths in the USA. Although COVID-19 affects all racial ethnicities, non-Hispanic Blacks have the highest mortality rates. Evidence continues to emerge, linking the disproportion of contagion and mortality from severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), a result of adverse social determinants of health. Yet, genetic predisposition may also play a credible role in disease transmission. SARS-CoV-2 enters cells by interaction between SARS-CoV-2 spike protein and the receptor molecule angiotensin converting enzyme 2 (ACE2) expressed on the surface of the target cells, such that polymorphisms and the expression level of ACE2 influence infectivity and consequent pathogenesis of SARS-CoV-2. Genetic polymorphisms in other multiple genes, such as acetylcholinesterase (AChE) and interleukin-6, are also closely associated with underlying diseases, such as hypertension and type 2 diabetes mellitus, which substantially raise SARS-CoV-2 mortality. However, it is unknown how these genetic polymorphisms contribute to the disparate mortality rates, with or without underlying diseases. Of particular interest is the potential that genetic polymorphisms in these genes may be influencing the disparity of COVID-19 mortality rates in Black communities. Here, we review the evidence that biological predisposition for high-risk comorbid conditions may be relevant to our ability to fully understand and therefore address health disparities of COVID-19 deaths in Blacks.
Mutations in the cystic fibrosis transmembrane conductance regulator gene (CFTR) affect the quantity and/or function of CFTR protein reaching the cell surface. Ivacaftor, a CFTR potentiator that enhances chloride transport, increases the channel-open probability of normal and dysfunctional CFTR. Initially approved for people with CF (pwCF) with G551D-CFTR gating mutations, ivacaftor demonstrated clinical benefit in pwCF with other gating mutations and certain residual function mutations, including R117H-CFTR, in clinical studies. We evaluated the long-term safety and efficacy of ivacaftor in pwCF aged 6years and older with non-G551D-CFTR ivacaftor-responsive mutations.

Efficacy and safety data from a phase 3, multicenter, open-label, extension study for participants from Study 110 (R117H-CFTR mutations), Study 111 (non-G551D-CFTR gating mutations), and Study 113 (n-of-1 pilot study in participants with residual CFTR function) were analyzed. Following washout from the randomized parent study, participants received oral ivacaftor 150mg once every 12h for 104weeks.

Forty-one of 121 participants completed treatment through 104weeks; 59 participants who did not complete the extension study continued treatment with commercial ivacaftor. The most common adverse events were pulmonary exacerbation (46.3%) and cough (33.9%). Most treatment-emergent adverse events were mild/moderate in severity and consistent with manifestations of CF or the ivacaftor safety profile. Rapid, durable improvement occurred across all efficacy endpoints.

Ivacaftor was generally safe and well tolerated with no new safety concerns for up to 104weeks in pwCF with ivacaftor-responsive mutations. The pattern of improvement across efficacy endpoints was durable and generally consistent with parent-study outcomes.

NCT01707290.This article is co-authored by a patient living with cystic fibrosis, and her treating physician. The first section of this commentary article is authored by a patient, who describes their experience of living with cystic fibrosis. The following section is authored by the patient's physician, who discusses the management of cystic fibrosis in the context of the patient's experiences.
