the cancer can spread to other parts of the body. This can also happen in reverse. Cancer detected in one part of the body may spread to the lungs to create an altogether new kind of lung tumor. This is called lung metastasis.
Pulmonary carcinoid (PC) tumours typically have a good prognosis, although metastases occur, and the disease may progress after a long period of time. Expression of orthopaedia homeobox protein (OTP) has been recognized as a possible independent prognostic marker in PCs. Immunohistochemical (IHC) OT...
MEN1, a bona fide tumor suppressor gene in endocrine tumors, exerts multiple biological functions including regulation of cell proliferation (Gao et al., 2008). Until recently, little has been known regarding the function of menin in controlling cancer cell migration. We found that menin ...
Rectal neuroendocrine tumor (NET) is the second most common gastrointestinal NET after small bowel NET, and accounts for 34% of all gastrointestinal NETs1. The incidence and prevalence of rectal NET have increased over time because of the widespread use of colonoscopy for colorectal cancer screening...
Our aim was to investigate the incidence of tumor recurrence in cases in which there was a discrepancy in the diagnosis of complete resection by pathologists and colonoscopists, especially in the lateral resection margin.We reviewed 245 patients with colorectal tumors that were treated by endoscopic...

High levels of CXCR2 transcript in lung carcinoid and low levels of CXCR2 expression in head and neck tumor with upregulation of most CXCR2 ligands have also been reported [12], [13]. The recruitment and activation of tumor-associated macrophages in the tumor microenvironment are considered ...
There are only two major types of lung cancers: small cell lung cancer and non-small cell lung cancer. Less than 5% of lung cancer tumors will take the form of a carcinoid tumor, while other cancerous tumors are even more rare, including adenoid cystic carcinomas, lymphomas, and sarcomas....
The urinary DASr among the primary lung cancer patients was classified according to histology and then compared between adenocarcinoma (n ¼ 186) and SqCC (n ¼ 57). NSCLC with other histologies (n ¼ 17, including 10 cases of large-cell carcinoma, 5 cases of carcinoid, and 2 cases ...
LRIG1 has been reported to be a tumor suppressor in gastrointestinal tract and epidermis. However, little is known about the expression, regulation and biological functions of LRIG1 in prostate cancer (PCa). We find that LRIG1 is overexpressed in PCa, but its expression correlates with better ...
