Background And Aim: Sarcoidosis is a granulomatous disease. Malignant tumors are accompanied rarely by granuloma reactions that mimic metastasis.
Methods: We present the case of a patient with possible advanced lung cancer with metastases to the mediastinal lymph nodes and bilateral ilia.
Results: Ilium biopsy revealed the presence of sarcoid-like reaction. Bronchoscopy and endobronchial ultrasound revealed an adenocarcinoma in the right upper lung lobe, with a negative mediastinal lymph node. The correct staging of lung cancer was achieved through pathological examination of the surgically removed lung tissues. Two years later, the lung cancer metastasized, and the patient underwent systemic treatment.
Conclusions: Coexistent sarcoid-like reaction may mimic metastatic lung cancer. A multidisciplinary approach and sequential diagnostic biopsies can prevent unnecessary surgery or inadequate treatment by distinguishing between coexistent sarcoidosis and metastatic lung cancer.

Background: Interstitial lung abnormalities (ILA) are a proposed imaging concept. Fibrous ILA have a higher risk of progression and death. Clinically, computed tomography (CT) examination is a frequently used and convenient method compared with pulmonary function tests.

Somatic stem cell pools comprise diverse, highly specialized subsets whose individual contribution is critical for the overall regenerative function. In the bone marrow, myeloid-biased hematopoietic stem cells (myHSCs) are indispensable for replenishment of myeloid cells and platelets during inflammatory response but, at the same time, become irreversibly damaged during inflammation and aging. Here we identify an extrinsic factor, semaphorin 4A (Sema4A), which non-cell-autonomously confers myHSC resilience to inflammatory stress.

Quantitative structure-property relationship (QSPR) modeling has emerged as a pivotal tool in the field of medicinal chemistry and drug design, offering a predictive framework for understanding the correlation between chemical structure and physicochemical properties. Topological indices are mathematical descriptors derived from the molecular graphs that capture structural features and connectivity, playing a crucial role in QSPR analysis by quantitatively relating chemical structures to their physicochemical properties and biological activities. Lung cancer is characterized by its aggressive nature and late-stage diagnosis, often limiting treatment options and significantly impacting patient survival rates.

AI decision support systems can assist clinicians in planning adaptive treatment strategies that can dynamically react to individuals' cancer progression for effective personalized care. However, AI's imperfections can lead to suboptimal therapeutics if clinicians over or under rely on AI. To investigate such collaborative decision-making process, we conducted a Human-AI interaction study on response-adaptive radiotherapy for non-small cell lung cancer and hepatocellular carcinoma.

Malignant tumors are among the major diseases threatening human survival in the world, and advancements in medical technology have led to a steady increase in their detection rates worldwide. Despite unique clinical presentations across the spectrum of malignancies, treatment modalities generally adhere to common strategies, encompassing primarily surgical intervention, radiation therapy, chemotherapy, and targeted treatments. Uncovering the genetic elements contributing to cancer cell proliferation, metastasis, and drug resistance remains a pivotal pursuit in the development of novel targeted therapeutics.
