Journal of Medical Research 2006;0(01):-
Objective To explore the clinical characteristics and diagnosis of primary small intestinal tumor(PSIT). Methods Retrospective analysis of the clinical and pathological data of the 31 PSIT cases was made. Results Duodenum was the most common site 67.74% for PSIT. The confirmed diagnosis rate was 54.84%(17/31)(duodenum was 66.67%,14/21; ileum and jejunum was 30%, 3/10, respectively ). 3 cases were benign tumors and 28 were malignant tumors.The adenocarcinoma was the most frequently seen malignant PSIT followed by lymphoma and often in duodenal. The features of the small intestinal tumor could be abdominal pain,abdominal mass,hemorrhage,obstruction,jaundice and fever.The chief method for diagnose was barium meal X-ray examination, especially with the hypotonic contrast X-ray examination and endoscopy.Superior mesenteric arteriography sometimes helped in determing site of gastrointestinal haemorrhage. CT scan could be helpful in diagnosis. Conclusion Duodenal adenocarcinoma is most common PSIT,followed by malignant lymphoma.Endoscopy is the best way to find out the tumor located in duodenum and hypotonic contrast X-ray examination is effective in diagnosis and locating of small bowl tumors.Superior mesenteric arteriography is a good way to find out angioma and leiomyoma. CT scanning are also helpful.

OBJECTIVE To investigate the expression and clinical significance of epidermal growth factor receptor (EGFR), the mutations of gene EGFR, KRAS and BRAF in sinonasal intestinal-type adenocarcinomas. METHODS We investigated the EGFR protein expression by immunohistochemistry method with antibodies targeting the extracellular domain, the intracellular domain, and the phosphorylated isoform in a series of 11sinonasal intestinal-type adenocarcinomas tissues. EGFR, KRAS, and BRAF mutational status were detected by DNA direct sequencing and Melt curve method.RESULTS The findings were analyzed with respect to clinical data, histological typing, and outcome of the patients. EGFR was expressed in 72.7% tumors with a focal distribution with both extracellular domain and intracellular domain, which showed a significantly correlation. p-EGFR was expressed in 9.1% tumors. 9.1% tumors had the mutation of EGFR gene in exon 19, 9.1% tumors had the mutation in exon 2 and exon 15 of gene KRAS and BRAF respectively. There was no association between these molecular features and the survival period of the patients. CONCLUSION The current study revealed various EGFR expression patterns in sinonasal intestinal-type adenocarcinomas, that indicated the tumor heterogeneity. Sinonasal intestinal-type adenocarcinomas share common alterations of the EGFR pathway as the mutation of EGFR, KRAS and BRAF genes, but with a lower frequency.

Melanoma is the most aggressive and lethal malignant tumor in skin cancers. Operation resection is used to treat stageⅠ/Ⅱmelanomas, but traditional operation, chemotherapy, and radiotherapy inflicts adverse effects on late-stage melanomas. StageⅢ/Ⅳmelanomas are some of the most ineffectively treated tumors with poor prognosis. As a cancer treatment, targeted immunotherapy in-hibits negative regulatory factors and enhances systemic anti-tumor immune effects. Radiotherapy not only kills tumor cells, but also en-hances systemic immune responses. Recent studies showed that targeted immunotherapy combined with radiotherapy can promote con-trol on local and distant tumors and prolong overall survival. The synergistic effects of these two therapies are superior to a single thera-py. This review summarized the progress on these research fields.
