A 57-year-old woman without significant medical history presented. She had suffered from dyspnoea for the past 2 days and persistent spasmodic abdominal complaints for the past 2 weeks. Physical examination revealed tachypnoea, tachycardia and slight abdominal tenderness. Laboratory investigations revealed hypoxaemia and a strongly elevated D-dimer level. Thorax radiography revealed no abnormalities and no indications for pulmonary embolism were revealed by the CT. Abdominal ultrasound revealed multiple enlarged lymph nodes. Shortly after admission and despite resuscitation the patient died. Autopsy revealed massive pulmonary tumour embolism that originated from a primary lymphogenic metastasized coecum carcinoma. Pulmonary tumour embolism is characterised by tumour cells in the pulmonary vascular system, which exhibit no continuity with parenchymal metastases. Due to the less than specific findings revealed by history taking, physical examination and additional tests, the condition is rarely diagnosed ante mortem.

Refractory small cell lung cancer with pancreatic metastasis: A case report.
Medicine (Baltimore)
January 2025
Department of Respiratory and Critical Care Medicine, The Affiliated Hospital of Inner Mongolia Medical University, Inner Mongolia, Hohhot, China.
Rationale: The occurrence of refractory small cell lung cancer (rSCLC) with pancreatic metastasis is a relatively rare clinical condition, which is typically accompanied by a poor prognosis and rapid disease progression.
Patient Concerns: A 65-year-old male farmer from China was diagnosed with limited-stage small cell lung cancer (SCLC) 8 months ago. Following 6 cycles of EP chemotherapy, the patient's tumor response showed partial relief.
Study on mechanism of Spatholobi Caulis in the treatment of the hand-foot skin reaction induced by targeted drug therapy based on network pharmacology and molecular docking: An observational study.
Medicine (Baltimore)
January 2025
Department of Traditional Chinese Medicine, Shanghai Fourth People's Hospital Affiliated to Tongji University of Medicine, Shanghai, China.
Based on network pharmacology and molecular docking methods, this study explored its active compounds and confirmed its potential mechanism of action against Hand-foot skin reaction induced by tumor-targeted drugs. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and UniProt Database were used to obtain the active ingredients and target proteins of Spatholobi Caulis. All hand-foot skin reaction (HFSR)-related targets were obtained with the help of the Human Gene Database, Online Mendelian Inheritance in Humans (OMIM), DisGeNET and DrugBank databases.

Department of Bone and Joint Surgery, the First Affiliated Hospital of Guangxi Medical University, Nanning, China.
Rationale: Synovial sarcoma (SS) is a rare and highly malignant soft tissue sarcoma. When SS occurs in atypical locations, it can present significant diagnostic challenges. We report a case of paraspinal SS initially misdiagnosed as spinal tuberculosis, highlighting the diagnostic difficulties and the importance of considering SS in the differential diagnosis.

Background: Few studies have explored the genetic changes and clinicopathological features of stage II/III gastric cancer (GC) patients with no tumor recurrence, early recurrence, or late recurrence after curative surgery.
Methods: In this study, 376 patients who underwent curative surgery for stage II/III GC were analyzed. The clinical and genetic features of patients with no recurrence, early recurrence (<2 years), and late recurrence (≥2 years) were compared.
Successful treatment of epidermal growth factor receptor exon 19 deletion non-small cell lung cancer with almonertinib after osimertinib-induced interstitial lung disease: A case report.
J Cancer Res Ther

Department of Oncology, The First Affiliated Hospital of Shandong First Medical University and Shandong Provincial Qianfoshan Hospital, Shandong Lung Cancer Institute, Shandong, China.
Osimertinib, a third-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), has revolutionized one of the standard most efficient treatments for EGFR mutation-positive non-small cell lung cancer (NSCLC). Osimertinib, a third-generation EGFR-TKI, is currently one of most efficient treatments in clinical practice. However, it has a potentially fatal side effect: interstitial lung disease (ILD).
