Atypical Carcinoid With Pulmonary Metastasis in an Adolescent.
Ann Thorac Surg Short Rep
December 2024
Advanced-stage atypical carcinoid tumors are seldom seen in the teenaged population. Comprehensive care, extending beyond mere cancer treatment, is essential. A 16-year-old boy received a diagnosis of a 13-mm nodule in the left S lung segment with signs suggesting interlobar pleural indentation.

We develop and validate machine learning models to predict combined resection based on preoperative contrast-enhanced computed tomography (CT).
Methods: This study included 212 patients with TETs (140 in the training cohort and 72 in the validation cohort) who underwent radical surgery.
Article Synopsis
- The study aimed to investigate how Helicobacter pylori infection affects gastric lesions in patients with non-eosinophilic gastrointestinal diseases (non-EoE EGIDs).
- A review of 75 patients found that common gastric findings included erythema, erosions, ulcers, and edema, with no significant differences based on gastric mucosal atrophy, which indicates H. pylori infection.
- The researchers concluded that gastric ulcers in non-EoE EGIDs should be considered when diagnosing idiopathic peptic ulcers, as there was no specific pattern in lesion frequency related to atrophic gastritis.
Background And Aims: The increasing prevalence of obesity has significantly contributed to the global burden of colorectal cancer and the precancerous colorectal adenoma (CRA). Gut microbiota vary at each stage of colorectal carcinogenesis and participate in energy homeostasis. Elucidating gut microbiotal characteristics in obesity-related CRA may help prevent and treat colorectal tumors; however, this remains unclarified.

- Esophageal cancers that penetrate the muscularis mucosa or submucosa can have a risk of lymph node metastasis after endoscopic resection, but the patterns of metastatic recurrence post-treatment are not well-studied.
- Researchers analyzed data from 220 patients in Japan who received additional treatments (esophagectomy, chemoradiotherapy, or radiation) after endoscopic resection between 2006 and 2017 to identify risk factors for metastatic recurrence.
- They found that lymphatic invasion is a key risk factor for recurrence, and while both esophagectomy and chemoradiotherapy show similar risks for metastasis, esophagectomy tends to have higher locoregional recurrence but better survival rates for patients who do experience
