Remarking the first step results of the role of f-18 fdg pet/ct in determining the positive position in the unknow cancer in the cancer national Hospital

SUMMARY

Carcinoma of unknown primary tumors (CUP) is present in 2% of all patients with malignant neoplasms. However, only 20% - 73% of primary sites are identified before the patients die. Currently, F-18 FDG PET/CT is widely used for the diagnosis of CUP. The objective of this study was to evaluate the role of F-18 FDG PET / CT in these patients.

Results: 30 patients with unclear cancers were treated with F-18 FDG PET / CT, the mean age of patients was 53.6 ± 9.7. There were 18/30 patients (60%) who were diagnosed with cancer. PET / CT (compared with pathology), the rest is false 12/30 BN (40%). Localized nodal metastases is an area of the neck. The most common pathological anomalies were squamous cell carcinoma (56.7%), adenocarcinoma (16.7%) and noncancerous cancers (26.7%).

Conclusion: F-18 FDG PET / CT is a useful method for detecting primary malignant sites in patients with primary tumors.
