"The sensitivity and specificity of FDG-PET for metastatic lymph node detection were 21-40% and 89-100%, respectively. The sensitivity and specificity for distant metastasis detection were 35-74% and 74-99%, respectively. Treatment response can be detectable at an earlier stage by PET than by CT, because FDG uptake by cancer cells decreases according to the treatment response. In summary, although PET has limitations such as frequent false-negative cases in signet-ring cell carcinoma and non-solid type poorly differentiated carcinoma, it can contribute to the selection of a more appropriate treatment modality by detecting distant metastases and treatment response."

AIM: Since positron emission tomography/computed tomography (PET/CT) has been introduced, many incidental findings have been identified. The aim of this study was to assess the clinical significance of incidental findings on PET/CT in patients with gastric cancer.
METHODS: A total of 421 patients with gastric cancer underwent PET/CT for initial staging. Incidental findings on PET/CT were classified into five categories according to clinical significance - normal variant, benign, probably benign, probably malignant, and definitely malignant. We obtained information regarding follow-up examinations, additional visits, final diagnosis of incidental findings and short-term medical costs for further evaluation.
RESULTS: Eight hundred eighty-two incidental findings were detected in 386 (91.7%) patients. Of 274 incidental findings classified as probably benign, probably malignant or definitely malignant, 130 required one or more additional investigations. Finally, 12 (9.2%) were proved to be associated with second primary malignancy or metastasis of gastric cancer. One hundred twenty-nine additional outpatient visits and 10 additional hospitalizations were needed for evaluating the incidental findings. The treatment strategy for gastric cancer was changed in one patient. The estimated cost of additional investigations was $US283 (95% CI: $US248-$US311) per patient.
CONCLUSION: Incidental findings on PET/CT were common. Although the incidental findings were suspicious of malignancy, most were benign with high costs for additional investigations.
