An analysis of melanoma epidemic characteristics and distribution in the eastern Chinese city Ningbo from 2011 to 2018.

Background: Melanoma is a malignant tumor with poor prognosis and increasing global incidence. Little is known about the burden of melanoma in eastern Chinese cities, as the results of previous studies are inconsistent or unclear.

Methods: In this study, we collected incidence rate data from the Ningbo National Health Information Platform, diagnostic data from the Ningbo Clinicopathological Diagnosis Center, and other relevant data from the Ningbo Bureau of Statistics to evaluate temporal trends and geographic variation in melanoma incidence and to analyze the relationship between melanoma incidence and medical resource availability.

Port-site metastasis of unsuspected gallbladder carcinoma with ossification after laparoscopic cholecystectomy: A case report.

Background: Unsuspected gallbladder carcinoma (UGC) refers to cholecystectomy due to benign gallbladder disease, which is pathologically confirmed as gallbladder cancer during or after surgery. Port-site metastasis (PSM) of UGC following laparoscopic cholecystectomy is rare, especially after several years.

Case Summary: A 55-year-old man presenting with acute cholecystitis and gallstones was treated by laparoscopic cholecystectomy in July 2008.

Ailanthone: A novel potential drug for treating human cancer.

Cancer is the second leading cause of death after cardiovascular disease. In 2015, >8.7 million people died worldwide due to cancer, and by 2030 this figure is expected to increase to ~13.

Clinical significance of the molecular heterogeneity of gastrointestinal stromal tumors and related research: A systematic review.

Gastrointestinal stromal tumors (GISTs) are the most commonly observed mesenchymal tumors of the digestive tract, and they originate from the interstitial cells of Cajal. GISTs can be divided into KIT/PDGFRA‑mutant GISTs and wild‑type GISTs based on the presence or absence of KIT/PDGFRA mutations. Wild‑type GISTs can be divided into succinate dehydrogenase complex (SDH)‑deficient GISTs and non‑SDH‑deficient GISTs.
