(18)F-FDG PET/CT in the evaluation of recurrent ovarian cancer: a prospective study on forty-one patients.

AIM: Many patients with ovarian cancer are at high risk of recurrence especially in the 2 years following first-line therapy. CA125 serum levels measurement associated to computed tomography (CT), ultrasound (US) and magnetic resonance imaging (MRI) are currently used during follow-up to detect recurrent disease. Unfortunately, in a relevant percentage of cases all of these traditional imaging techniques provide a significant number of doubtful/equivocal results or turn out negative even in presence of elevated Ca125 levels. Aim of our study was to evaluate sensitivity, specificity and accuracy of (18)F-FDG PET/CT in a group of patients with suspicion of ovarian cancer recurrence. METHODS: We prospectively evaluated 41 patients with a mean age of 59.4 years who had been previously treated for ovarian cancer with surgery and radio-chemotherapy or radio-chemotherapy alone. Following the performance of traditional radiologic imaging (US, CT, MRI) and Ca125 measurement, all patients underwent additional (18)F-FDG PET/CT. PET/CT results were compared with histologic findings or clinical, laboratory and repeated traditional imaging techniques during subsequent follow-up data. RESULTS: Of 41 patients 32 had a positive PET-CT (30 true positive, two false positive) whereas nine a negative PET/CT (five true negative, four false negative). Overall, in our experience (18)F-FDG PET/CT provided a good sensitivity (88.2%), specificity (71.4%) and accuracy (85.4%), superior to that reported in literature for traditional radiologic imaging. CONCLUSIONS: It can be concluded that (18)F-FDG PET/CT appears to be a useful and accurate tool in disclosing early recurrent ovarian cancer.     

Whole body positron emission tomography with 18F-fluoro-2-deoxyglucose for the detection of recurrent ovarian cancer

Although many cancers can be detected by whole-body positron emission tomography (PET) with 18F-fluoro-2-deoxyglucose (FDG), there has been limited clinical experience with FDG-PET for the detection of recurrent ovarian cancers. Therefore, the aim of this study was to evaluate the clinical value of FDG-PET in the detection of recurrent ovarian cancer. Whole body FDG-PET scans were performed on 24 women who had previous histories of ovarian cancer and treatment with surgery and chemotherapy. All patients also underwent physical examination, laboratory testing of serum CA-125 level and pelvic-abdominal-chest computed tomography (CT) or magnetic resonance imaging (MRI). The results of FDG-PET scans were correlated with serum CA-125 level, CT/MRI and operative pathology results. The diagnostic sensitivity was 90.9%, 90.9% and 90.9%, specificity was 92.3%, 76.9% and 46.2% and accuracy was 91.7%, 83.3% and 66.7% for FDG-PET, serum tumor marker of CA-125 level and CT/MRI in detecting recurrent ovarian cancer, respectively. FDG-PET is a useful diagnostic tool in detecting recurrent ovarian cancers with high specificity as compared with the serum tumor marker CA-125 level and the conventional CT/MRI morphological imaging methods.     

Diagnostic Performance of F-18 FDG PET/CT Compared with CA125, HE4, and ROMA for Epithelial Ovarian Cancer

Objective: This study aimed to examine the diagnostic performance of F-18 fluorodeoxyglucose positron emission tomography with computed tomography (F-18 FDG PET/CT) compared with cancer antigen 125 (CA125), human epididymis protein 4 (HE4), and risk of ovarian malignancy algorithm (ROMA) score to distinguish epithelial ovarian cancer from benign tumors. Methods: A total of 46 patients with pelvic masses, who underwent F-18 FDG PET/CT, CA125, and HE4 before surgery between January 2015 and December 2018, were included in this retrospective study. The diagnostic performance of CA125, HE4, ROMA score, and maximum standardized uptake value (SUVmax) to differentiate epithelial ovarian cancer from benign pelvic tumors was examined by receiver operating characteristic curve analysis. Results: Among the 46 patients, 28 were cases of ovarian cancers and 18 were of benign. The mean values of CA125, HE4, ROMA score, and SUVmax were significantly higher in the ovarian cancer group than the benign group. In early cancer stages (stages I and II), Area under the curve for SUVmax was significantly higher than CA125 and ROMA score (0.778 for CA125, 0.753 for HE4, 0.682 for ROMA score, and 0.922 for SUVmax). Conclusion: SUVmax using F-18 FDG PET/CT showed a high diagnostic accuracy for differentiating epithelial ovarian cancer from benign pelvic tumors, including early stage ovarian cancer. F-18 FDG PET/CT can be a useful modality for the assessment of pelvic mass.

Abstract：

Objective To evaluate the clinical value of regular and dual-time-point 18-fluorodeoxyglucose positron emission tomography-CT(FDG PET/CT)imaging for recurrence and metastasis in esophageal carcinoma(EC)after curative esophagectomy. Methods A retrospective study was done on 48 patients received curative esophagectomy, who underwent FDG PET/CT scans to detect doubtful recurrent or metastatic lesions. The diagnostic accuracy of FDG PET-CT was assessed with the help of pathological findings as well as clinical or follow-up data. Using Fisher's Exact Test from SPSS 11.5 to analyze the data.Results Of the 48 patients, after a median follow-up of 21.5 months, 61 sites of local and regional recurrence or metastasis were finally confirmed in 34 patients. The sensitivity, specificity and accuracy of regular FDG PET/CT imaging in detecting recurrence of all sites were 93.44%, 74.29% and 86.46%respectively. The specificity and accuracy of local recurrence and regional metastasis were 57.14% ,78.95% and 77.78% ,84.62%, respectively. The sensitivity, specificity and accuracy of dual-time-point FDG PET/ CT imaging in detecting local and regional recurrence(96.97% ,96.00% and 96.55%)were higher than those of regular FDG PET/CT(90.90%, 72.00% and 82.76%)and there were significant differences of specificity and accuracy(P = 0.049, P = 0.029). Conclusions Regular FDG PET/CT imaging is highly effective in detecting recurrence and metastasis in EC patients after curative esophagectomy despite the low specificity and accuracy. Dual-time-point FDG PET/CT imaging can elevate the specificity and accuracy.

Breast cancer recurrence diagnosis suspected on tumor marker rising: value of whole-body 18FDG-PET/CT imaging and impact on patient management

BACKGROUND:

Breast cancer recurrence is often suspected on tumor marker rising in asymptomatic patients. The value of fluorine‐18 fluorodeoxyglucose (18FDG)–positron emission tomography/computed tomography (PET/CT) imaging to detect recurrence and its subsequent impact on patient management were retrospectively assessed.

METHODS:

PET/CT scans were performed on 228 asymptomatic patients (mean, 60.8 years; range, 30‐91 years) presenting with rising CA 15‐3 and/or CEA serum levels.

RESULTS:

PET/CT scans were positive in 181 patients (79.5%) and normal in 47 patients, whereas 187 true recurrences were diagnosed. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of PET/CT imaging for detection of breast cancer recurrence were 93.6%, 85.4%, 96.7%, 74.5%, and 92.1%, respectively. When compared with the standard workup available in 67 patients, PET/CT imaging had a higher sensitivity and accuracy (94.5% vs 33% and 94% vs 48%, respectively). Recurrences were confirmed by pathology, conventional imaging techniques, or radiological and clinical follow‐up beyond 1 year (mean, 34 months; range, 12‐67 years) in 32, 130, and 25 patients, respectively. The diagnosis of recurrence led to a treatment modification in 123 patients (54%).

CONCLUSIONS:

18FDG‐PET/CT imaging is an efficient technique to detect breast cancer recurrence suspected on tumor marker rising in asymptomatic patients. It may thus contribute to improve patient management, providing an earlier diagnosis with complete whole‐body staging as a “one‐stop shop” procedure.

Metabolic tumor burden predicts prognosis of ovarian cancer patients who receive platinum‐based adjuvant chemotherapy

Volumetric parameters of positron emission tomography–computed tomography using 18F‐fludeoxyglucose (¹⁸F‐FDG PET/CT) that comprehensively reflect both metabolic activity and tumor burden are capable of predicting survival in several cancers. The aim of this study was to investigate the predictive performance of metabolic tumor burden measured by ¹⁸F‐FDG PET/CT in ovarian cancer patients who received platinum‐based adjuvant chemotherapy after cytoreductive surgery. Included in this study were 37 epithelial ovarian cancer patients. Metabolic tumor burden in terms of metabolic tumor volume (MTV) and total lesion glycolysis (TLG), clinical stage, histological type, residual tumor after primary cytoreductive surgery, baseline serum carbohydrate antigen 125 (CA125) level, and the maximum standardized uptake value (SUV_max) were determined, and compared for their performance in predicting progression‐free survival (PFS). Metabolic tumor volume correlated with CA125 (r = 0.547, P < 0.001), and TLG correlated with SUV_max and CA125 (SUV_max, r = 0.437, P = 0.007; CA125, r = 0.593, P < 0.001). Kaplan–Meier analysis showed a significant difference in PFS between the groups categorized by TLG (P = 0.043; log–rank test). Univariate analysis indicated that TLG was a statistically significant risk factor for poor PFS. Multivariate analysis adjusted according to the clinicopathological features was carried out for MTV, TLG, SUV_max, tumor size, and CA125. Only TLG showed a significant difference (P = 0.038), and a 3.915‐fold increase in the hazard ratio of PFS. Both MTV and TLG (especially TLG) could serve as potential surrogate biomarkers for recurrence in patients who undergo primary cytoreductive surgery followed by platinum‐based chemotherapy, and could identify patients at high risk of recurrence who need more aggressive treatment.
