Soft tissue sarcomas (STSs) account for less than 1% of adult solid tumors and about 7% of pediatric malignancies, causing 2% of cancer-related deaths. With the advent of PET-computed tomography (CT), the value of (18) fluorine-2-fluoro-2-deoxy-d-glucose (FDG) PET imaging to improve the management of STSs has been explored. FDG PET imaging has been found useful in restaging and treatment response assessment. This article reviews current knowledge and application of FDG PET-CT in initial diagnosis, staging, restaging, treatment response monitoring, and prognosis, with a brief overview of the most common histologic subtypes of STS...

BACKGROUND & AIMS: Nutrition support is recommended in cachexic patients with cancer. However, there is no clear evidence about its impact on tumour growth. Glycolysis, which is usually higher in cancer than normal cells, can be monitored by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT) imaging that is widely used for cancer staging and therapy efficacy assessment. Here, we used 18 F-FDG PET/CT imaging to investigate whether artificial nutrition has an impact on tumour glucose metabolism in patients with cancer and cachexia...

INTRODUCTION: Soft-tissue sarcomas (STS) are rare types of tumors that have variable levels of tumor differentiation. F-18 fluorodeoxyglucose positron emission tomography (FDG PET) has been established as an useful tool for STS patients, and the metabolic tumor volume (MTV) and total lesion glycolysis (TLG) are reported to be useful in various cancers. We compared the diagnostic value of four PET parameters (maximum standardized uptake value [SUVmax], SUVmean, MTV, and TLG) from two acquisition timings for predicting the expression of the pathological marker of cell proliferation Ki-67, based on pathological investigation...

A 64-year-old man with pulmonary non-tuberculous mycobacteriosis(pulmonary NTM) who had been treated by antituberculous chemotherapy, developed a new nodule of 8 mm in size in the segment 3 of the right upper lobe. The cavity of 4.0 cm in size in the segment 1+2 of the left upper lobe due to Mycobacterium avium infection was preexisted. Radiologically, new nodule of the right lung was suspected to be lung cancer. Left upper lobe apical trisegmentectomy was performed at first. Three months later, enlarging of the right lung nodule with increased fluoro-2-deoxy-D-glucose(FDG) activity was noted, and the diagnosis of lung cancer was made by transbronchial lung biopsy(TBLB)...
