Abstract
A 69-year-old woman presented to our department with the chief complaint of diarrhea. She had undergone left nephrectomy for renal cancer 14 years earlier. Three years earlier, metastasis was detected in the left retroperitoneal cavity, and pazopanib administration was initiated. In the 29th month after the start of chemotherapy, the patient developed diarrhea, and on the 31st month, computed tomography showed thickening of the intestinal wall. Colonoscopy revealed white villi, intramucosal hemorrhage in the terminal ileum, and rough inflammatory mucosa with inflammatory polyps extending from the transverse to the sigmoid colon. Suspecting pazopanib-induced enteritis, we discontinued the medication, and the diarrhea resolved within 3 days. On the 21st day after discontinuation, colonoscopy revealed that the inflammatory polyps had shrunk, and the inflammatory findings had improved. Biopsy of the white villi of the ileum revealed histiocytes. The patient resumed treatment with pazopanib at 400 mg/day and developed soft stool on the 7th day after resumption. Compared with other tyrosine-kinase inhibitor-induced enteritis cases, this case showed less bleeding and more extensive inflammatory findings. There are similarities as well as differences from cases of previously reported pazopanib-induced enteritis. The mechanisms and characteristics of this disease require further investigation.

Abstract
INTRODUCTION Imatinib, a tyrosine kinase inhibitor, is the first-line therapy for patients with KIT mutation in gastrointestinal stromal tumor (GIST). Nausea, vomiting, diarrhea, dyspepsia and abdominal pain are common gastrointestinal adverse reactions of imatinib, but imatinib-induced ulcerative colitis (UC) is rarely reported. CASE REPORT We presented a case of UC induced by imatinib in a 56-year-old male patient who experienced this adverse event after 5 years of imatinib 400 mg/d treatment following GIST resection. MANAGEMENT AND OUTCOME The patient's diarrhea and bloody stools showed significant improvement following the discontinuation of imatinib therapy and administration of antidiarrheal medications. Then, imatinib was restarted at a daily dosage of 400 mg. DISCUSSION UC is a rare adverse event associated with imatinib. Physicians should consider the possibility of UC induced by imatinib when patients present with diarrhea and bloody stool after receiving imatinib treatment. This case offered objective evidence of UC induced by imatinib.

Abstract
Replacement of first-generation or second-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) with third-generation EGFR-TKIs remains the current standard of care for T790M mutations in patients with non-small cell lung cancer. Osimertinib is one of the first third-generation EGFR-TKIs to be approved and is also the most widely studied in clinical research. There has been widespread concern about the adverse effects of osimertinib such as cardiotoxicity and interstitial lung disease, but few articles have reported severe thrombocytopenia after osimertinib treatment. This article reports a 64-year-old woman with non-small cell lung cancer initially diagnosed with cT2aN1M1a, EGFR p.L858R, who developed disease progression and T790M after 32 months of first-line treatment with gefitinib (250 mg/day) before switching to second-line treatment with osimertinib (80 mg/day). Severe thrombocytopenia and active bleeding occurred after treatment with osimertinib, which improved with recombinant human thrombopoietin and platelet transfusion. Treatment was replaced with aumolertinib (110 mg/day). After platelet stabilization with aumolertinib treatment in combination with chest radiotherapy, this patient had progression-free survival for 9 months and overall survival for over 45 months. In conclusion, from our experience, aumolertinib has good efficacy and mild adverse effects, and is a good choice for non-small cell lung cancer patients with T790M, especially for patients at high risk of thrombocytopenia.

Abstract
An increasing number of immunomodulators, either anti-inflammatory or immunity-enhancing, have brought about a revolutionary effect in the management of a variety of autoimmune disorders and malignancies. However, their ability to cause gastrointestinal (GI) injury and induce GI symptoms has been increasingly and unexpectedly recognized. GI injury associated with immunomodulators may demonstrate various histologic and endoscopic patterns. Optimal diagnosis and treatment require a multidisciplinary approach. This review aims to provide an overview of the literature on its pathogenesis, the clinical, endoscopic, and histologic features, and suggested approaches to manage these newly recognized immunomodulator-induced GI adverse effects (AEs). We also reviewed current biomarkers predictive of GI toxicity and potential risk factors to identify susceptible patients. In addition, these immune-mediated AEs were compared with inflammatory bowel disease, a well-documented form of inflammation-driven GI injury. We hope this review will raise awareness and vigilance among clinicians of these entities to increase early diagnosis and rapid referral to specialist care.
