Nevus-associated acral melanoma has lower risk of recurrence and mortality than de novo acral melanoma: A multicenter, retrospective analysis of 482 patients.

Background: It is unknown whether acral melanomas (AMs) associated with pre-existing nevi have similar risk to other AMs.

Objective: To compare risk of recurrence and death between AMs associated with pre-existing nevi and de novo AMs.

Methods: We conducted a multicenter retrospective cohort study involving patients diagnosed with AMs between February 2011 and November 2022.

Clinical performance of metagenomic next-generation sequencing for the rapid diagnosis of talaromycosis in HIV-infected patients.

Background: Talaromycosis is an invasive endemic mycosis caused by the dimorphic fungus (, TM). It mainly affects immunodeficient patients, especially HIV-infected individuals, which causes significant morbidity and mortality. Culture-based diagnosis takes a long turnaround time with low sensitivity, leading to treatment delay.

[Association between the ALK Gene Status and the Efficacy of First-line Pemetrexed Chemotherapy in Patients with Advanced Lung Adenocarcinoma].

Background: Anaplastic lymphoma kinase (ALK) is one of the major driver genes of non-small cell lung cancer (NSCLC). Several studies have shown that the efficacy of pemetrexed in ALK-positive lung cancer is controversial. The aim of this study is to explore the efficacy of pemetrexed-based chemotherapy in patients with ALK-positive and negative lung adenocarcinoma.
