OBJECTIVE The aim of this study was to evaluate the prognostic significance of some metabolic parameters measured by (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) in patients with small cell lung cancer (SCLC). METHODS We retrospectively reviewed 98 patients with pathologically proven SCLC who underwent(More)
PURPOSE To determine the optimal method of using (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) to estimate gross tumor length in esophageal carcinoma. METHODS AND MATERIALS Thirty-six patients with esophageal squamous cell carcinoma treated with radical surgery were enrolled. Gross tumor volumes (GTVs) were delineated using three(More)
Lung cancer is the leading cause of cancer death in males and the second leading cause of death in females worldwide. Non-small-cell lung cancer (NSCLC) is the main pathological type of lung cancer, and most newly diagnosed NSCLC patients cannot undergo surgery because the disease is already locally advanced or metastatic. Despite chemoradiotherapy and(More)
UNLABELLED The primary aim of this study was to use serial (18)F-3'-deoxy-3'-fluorothymidine (FLT) PET/CT to measure tumor cell proliferation during radiotherapy of squamous cell carcinoma (SCC) of the esophagus. METHODS Twenty-one patients with inoperable locally advanced SCC of the esophagus underwent serial (18)F-FLT PET/CT during radiotherapy. Each(More)
OBJECTIVES To determine the prognostic value of standardized uptake value (SUV) of F-fluorodeoxyglucose by serial positron emission tomography and computed tomography (PET/CT) in nonsmall cell lung cancer (NSCLC). METHODS Forty-seven patients (37 male, 10 female) with NSCLC in stage III were enrolled. All patients had at least 2 serial(More)
PURPOSE To evaluate the efficacy of dual-time-point F-18 fluorodeoxyglucose positron emission tomography (FDG PET)/ computed tomography (CT) for mediastinal nodal staging in non-small-cell lung cancer patients with lung comorbidity. MATERIALS AND METHODS Fifty-three pathologically proven non-small-cell lung cancer patients with pulmonary comorbidity and(More)
The aim of the present study was to investigate the relationship between FDG uptake and clinical stage for non-small cell lung cancer. The patients who were histologically or cytologically proven to be adenocarcinoma (AC) or squamous cell carcinoma (SCC) lung cancer and conducted FDG PET/CT staging were retrospectively reviewed. The FDG uptake was(More)
Epidermal growth factor receptor (EGFR) was expressed widely in NPC. The aim of this study was to investigate the difference of expression of EGFR and Ki67 in primary and recurrence of NPC to supply a micro-evidence of anti-EGFR targeted maintenance therapy for NPC. A retrospective review of 40 patients with clinical stages I-IV b was performed.(More)
PURPOSE We conducted a retrospective analysis to assess the feasibility of involved field irradiation (IFI) in elderly patients with esophageal squamous cell cancer (ESCC). MATERIALS AND METHODS We performed a retrospective review of the records of elderly patients (≥ 70 years) with unresectable ESCC and no distant metastases who received treatment with(More)
Increased serum tumor biomarkers are usually associated with huge tumor burden, but the prognostic value of these markers remains controversial. The serum levels of carcinoembryonic antigen (CEA), nerve cell-specific enolase, and lactate dehydrogenase in 281 patients with small cell lung cancer (SCLC) were analyzed in this study. Increased serum CEA levels(More)
