The treatment landscape for advanced hepatocellular carcinoma (HCC) has recently changed and become relatively confusing. Head-to-head comparisons between most of the available agents have not been performed and are less likely to be examined in a prospective fashion in the future. Therefore, a network meta-analysis (NMA) is helpful to compare different agents from across different trials.OBJECTIVE To evaluate comparative effectiveness of different systemic treatments in advanced patients with HCC across lines of therapy.DATA SOURCES We searched various databases for abstracts and full-text articles published from database inception through March 2020.STUDY SELECTION We included phase 3 trials evaluating different vascular endothelial growth factor inhibitors (VEGFis), checkpoint inhibitors (CPIs), or their combinations in advanced HCC, in the first-line or refractory setting. DATA EXTRACTION AND SYNTHESISThe reporting of this systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. The overall effect was pooled using the random effects model. MAIN OUTCOMES AND MEASURES Outcomes of interest included overall (OS) and progression-free survival (PFS).FINDINGS Fourteen trials (8 in the first-line setting and 6 in the second-line setting) at low risk of bias were included. The 8 trials in the first-line setting encompassed a total of 6290 patients, with an age range of 18 to 89 years. The 5 trials included in the second-line analysis encompassed a total of 2653 patients, with an age range of 18 to 91 years. Network meta-analysis showed the combination of atezolizumab and bevacizumab was superior in patients with HCC treated in the first-line setting compared with lenvatinib (HR, 0.63; 95% CI, 0.44-0.89), sorafenib (HR, 0.58; 95% CI, 0.42-0.80), and nivolumab (HR, 0.68; 95% CI, 0.48-0.98). In the refractory setting, NMA showed that all studied drugs had PFS benefit compared with placebo. However, this only translated into OS benefit with regorafenib (HR, 0.62; 95% CI, 0.51-0.75) and cabozantinib (HR, 0.76; 95% CI, 0.63-0.92) compared with placebo. In the NMA of patients with α-fetoprotein (AFP) levels of 400 ng/mL or greater, regorafenib, cabozantinib, and ramucirumab showed PFS and OS benefit compared with placebo with no superiority of an active drug compared with any others.CONCLUSIONS AND RELEVANCE This systematic review and NMA of 14 trials found that atezolizumab and bevacizumab in combination is now considered the standard of care in the first-line setting in patients with advanced HCC. Regorafenib and cabozantinib are preferred options in refractory patients, with ramucirumab as an additional option in those with levels of AFP of 400 ng/mL or higher. Future trials should focus on other potential combinations and best treatment strategy in patients with prior VEGFi/CPI exposure.
Limited-stage small-cell lung cancer (SCLC) occurs in only one third of patients with SCLC, but it is potentially curable. Combined-modality therapy (chemotherapy and radiotherapy) has long been the mainstay of therapy for this condition, but more recent data suggest a role for surgery in early-stage disease. Prophylactic cranial irradiation seems to improve outcomes in patients who have responded to initial therapy. This review addresses the practical aspects of staging and treatment of patients with limited-stage SCLC.
BackgroundCDKN2A and TP53 mutations are recurrent events in melanoma, occurring in 13.3% and 15.1% of cases respectively and are associated with poorer outcomes. It is unclear what effect CDKN2A and TP53 mutations have on the clinical outcomes of patients treated with checkpoint inhibitors. MethodsAll patients with cutaneous melanoma or melanoma of unknown primary who received checkpoint inhibitor therapy and underwent genomic profiling with the 50-gene Mayo Clinic solid tumor targeted cancer gene panel were included. Patients were stratified according to the presence or absence of mutations in BRAF, NRAS, CDKN2A, and TP53. Patients without mutations in any of these genes were termed quadruple wild type (Quad WT ). Clinical outcomes including median time to progression (TTP), median overall survival (OS), 6-month and 12-month OS, 6-month and 12-month without progression, ORR and disease control rate (DCR) were analyzed according to the mutational status of CDKN2A, TP53 and Quad WT .
Over the past decade, significant advances have been achieved in the diagnostic testing, treatment, and prognosis of advanced non–small-cell lung cancer (NSCLC). One of the most significant developments was the identification of specific gene alterations that define subsets of NSCLC. In 2007, ROS1 rearrangements were first described and observed in approximately 1%-2% of patients with NSCLC. Currently, crizotinib remains the therapy of choice for advanced ROS1-rearranged NSCLC without CNS metastases, while entrectinib has emerged as the preferred option for those with CNS metastases. The next-generation inhibitors under development are more potent, have better CNS efficacy, and can overcome important resistance mutations. In this review, we focus on the management of patients with advanced NSCLC harboring a ROS1 rearrangement. We aim to provide insight into the diagnosis, treatment approach, and emerging treatments in this subgroup of NSCLC.
e20029 Background: Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a pulmonary disorder with neuroendocrine cell proliferation with potential progression to lung neuroendocrine tumor (Lu-NET). Optimal diagnostic and treatment strategies have yet to be well defined. Herein, we aim to describe the Mayo Clinic experience with DIPNECH. Methods: A retrospective analysis was performed of patients diagnosed with DIPNECH within Mayo Clinic between January 2000-Febuary 2019. Cases were identified from clinical databases at Mayo Clinic. Data on demographics, disease characteristics, time of diagnosis, surgery, and last follow up date were extracted. Extent of symptom burden, treatment approaches, disease progression, and disease-free survival (DFS) were evaluated by chart review. Results: A total of 59 patients were identified with a median age of 63(43-81) years. The cohort was predominantly female (93.2%) and non-smoking (76.3%). Most patients (86.4%) had symptomatic disease with chronic cough being the most common (71.2%) followed by exertional dyspnea (44.1%). Imaging typically showed bilateral lung nodules (93.2%) with mosaic attenuation noted 69.5% of the time. Surgical resection was frequently completed to confirm diagnosis (94.9%). Most patients received inhaled glucocorticoids combined with a beta agonist (79.7%). Oral steroid use was seen in 49.2% of patients whereas a somatostatin analog was used in 15.3% following the diagnosis of DIPNECH. These medical interventions led to symptom relief in 23.7% of the patients. The median follow up for all patients was 19.5 months. Progression of tumorlets was seen in 48.7% of patients with only 7(17.9%) patients progressing to a diagnosis of Lu-NET. The 3-year DFS was 90.5%. Conclusions: This is amongst the largest studies completed evaluating DIPNECH patients. DIPNECH remains a rare disease more commonly diagnosed in women in their early 60’s. DIPNECH appears to have an indolent course with obstructive symptoms being the most common finding. A minority of patients experienced symptom relief with therapy. Overall, DIPNECH appears to have a low risk of progressing to Lu-NET based on the observation of this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
