Background/aim: Small cell cancer of the esophagus (SCCE) is an extremely rare entity with an aggressive clinical course, thus early diagnosis and treatment are important for improved survival.
Case Report: A 35-year-old male presented with dysphagia, loss of appetite and weight loss. Diagnostic workup revealed an esophageal mass, which was diagnosed as primary non-Hodgkin lymphoma (NHL) on initial biopsy. Despite receiving rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy for 3 months, there was an interval increase in the size of the esophagus mass, which unveiled underlying SCCE. A re-review of the previous biopsy specimen with immunohistochemical staining confirmed the initial diagnosis as SCCE as well. Despite 4 cycles of platinum-based chemotherapy and radiotherapy, the malignancy progressed and proved fatal.
Conclusion: SCCE and non-Hodgkin lymphomas are rare entities, whose morphologies can be diagnostically challenging, hence they require special immunostaining for accurate diagnosis. Prompt diagnosis and initiation of treatment can confer better quality of life and survival.

Could less be enough: sublobar resection vs lobectomy for clinical stage IA non-small cell lung cancer patients with visceral pleural invasion or spread through air spaces.
Int J Surg
January 2025
Department of Thoracic Surgery, West China hospital, SiChuan University, Chengdu, China.
Background: While recent randomized controlled trials have demonstrated that sublobar resection is non-inferior to lobectomy, the comparative efficacy of these procedures remains uncertain for early-stage non-small cell lung cancer (NSCLC; ≤ 3 cm) exhibiting invasive features postoperatively, such as visceral pleural invasion (VPI) or spread through air spaces (STAS).
Materials And Methods: To identify eligible studies, a comprehensive search of PubMed, Embase, MEDLINE, the Cochrane Library, and Web of Science was conducted through 25 July 2024. Studies were screened according to predefined criteria in accordance with PRISMA guidelines.
PP2A Attenuates Thoracic Aneurysm and Dissection in Mouse Models of Marfan Syndrome.

Background: Recent studies show that hyperactivation of mTOR (mammalian target of rapamycin) signaling plays a causal role in the development of thoracic aortic aneurysm and dissection. Modulation of PP2A (protein phosphatase 2A) activity has been shown to be of significant therapeutic value. In light of the effects that PP2A can exert on the mTOR pathway, we hypothesized that PP2A activation by small-molecule activators of PP2A could mitigate AA progression in Marfan syndrome (MFS).

The zona glomerulosa (ZG) synthesizes the mineralocorticoid aldosterone. The primary role of aldosterone is the maintenance of volume and electrolyte homeostasis. Aldosterone synthesis is primarily regulated via tightly controlled oscillations in intracellular calcium levels in response to stimulation.

Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare disease, with unique diagnostic challenges and often dismal outcome. There are no widely accepted treatment guidelines available. Lymphoma-like regimens with or without autologous or allogenic transplantation were the cornerstone of most therapeutic concepts.

Critical Assessment of Computational Hit-Finding Experiments (CACHE) Challenges emerged as real-life stress tests for computational hit-finding strategies. In CACHE Challenge #1, 23 participants contributed their original workflows to identify small-molecule ligands for the WD40 repeat (WDR) of LRRK2, a promising Parkinson's target. We applied the FRASE-based hit-finding robot (FRASE-bot), a platform for interaction-based screening allowing a drastic reduction of the explorable chemical space and a concurrent detection of putative ligand-binding sites.
