AI Article Synopsis
- * Diagnostic tests, including cytologic and immunocytochemical examinations, indicated that the mass was a neuroendocrine tumor, with no signs of metastasis found during further staging.
- * Ultimately, the excised tumor's histopathologic analysis confirmed the initial cytologic diagnosis, highlighting the rarity of primary hepatic neuroendocrine tumors with exophytic growth and the effectiveness of cytology and immunocytochemistry for diagnosis.
Article Abstract
Background: Primary hepatic neuroendocrine tumor with exophytic growth is a unique entity.
Case: A 74-year-old man presented to our hospital with abdominal discomfort. Diagnostic imaging procedures revealed a 15 x 10-cm mass in the liver with exophytic growth. The tumor was adjacent to the stomach, and clinical suspicion of gastrointestinal stromal tumor of the stomach was very strong initially. The cytologic and immunocytochemical examination of aspirated material showed features similar to those of neuroendocrine tumor. Systemic staging procedures showed no evidence of metastasis or other primary site. The histopathologic results of the excised tumor confirmed the cytologic diagnosis.
Conclusion: Primary neuroendocrine tumor with exophytic growth is a rare entity and can be diagnosed with cytology and immunocytochemistry.

Unlabelled: The purpose of the study: to evaluate the impact of a comprehensive rehabilitation program on physical health indicators, such as weight restoration and improvement of functional capabilities of patients, psychoemotional state of patients, reduction of complications after surgical treatment.
Material And Methods: Observations were conducted on 148 patients diagnosed with melanoma of various localizations, who were divided into two groups by simple randomization: study (=77) and control (=71). The study group received surgical treatment in combination with rehabilitation programs (psychotherapy, nutritional support, general magnetic therapy), while the control group received only standard surgical treatment.
RET Inhibitor SPP86 Triggers Apoptosis and Activates the DNA Damage Response Through the Suppression of Autophagy and the PI3K/AKT Signaling Pathway in Melanoma Cells.

Background: Melanoma is a highly lethal form of skin cancer, and effective treatment remains a significant challenge. SPP86 is a novel potential therapeutic drug. Nonetheless, the specific influence of SPP86 on autophagy, particularly its mechanisms in the context of DNA damage and apoptosis in human melanoma cells, remains inadequately understood.

Small-cell lung cancer (SCLC) is an aggressive neuroendocrine tumor with a poor prognosis. Although the addition of immunotherapy to chemotherapy has modestly improved outcomes, most patients rapidly develop resistance. Resistance to immunotherapy can be broadly categorized into primary resistance and acquired resistance, as proposed by the Society for Immunotherapy of Cancer (SITC) consensus definition.

Granular cell tumors are rare neoplasms originating from Schwann cells found in various organs. GCTs are seldom reported in the gastrointestinal tract. Pre-operative detection and diagnosis of colonic GCTs is challenging since the tumors are mainly asymptomatic, small, slow-growing, and submucosal.

Background: Cancer treatments are still limited by various challenges, such as off-target drug delivery, posttreatment inflammation, and the hypoxic conditions in the tumor microenvironment; thus, the development of effective therapeutics remains highly desirable. Exosomes are extracellular vesicles with a size of 30-200 nm that have been widely applied as drug carriers over the last decade. In this study, melanoma-derived exosomes were used to develop a perfluorocarbon (PFC) drug nanocarriers loaded with indocyanine green (ICG) and camptothecin (CPT) (ICFESs) for targeted cancer photochemotherapy.
