Rev Esp Med Nucl Imagen Mol 2023; 42:353-358. [PMID: 37172933 DOI: 10.1016/j.remnie.2023.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 03/29/2023] [Accepted: 03/30/2023] [Indexed: 05/15/2023]
Abstract
OBJECTIVE The present study investigates the ability of non-invasive contribution of positron emission tomography (PET)/computed tomography (CT) to distinguish between benign pleural effusions (BPE) and malignant pleural effusions (MPE) in patients diagnosed with ovarian carcinoma (OC). MATERIAL AND METHODS Included in the study were 32 OC patients with a PE diagnosis. The cases with BPE and MPE were compared in terms of the PE maximum standardized uptake value (SUVmax), PE SUVmax/mean standardized uptake (SUVmean) value of the mediastinal blood pool (TBRp), the presence of pleural thickening, the presence of supradiaphragmatic lymph node, unilateral or bilateral PE, pleural effusion diameter, patient age and CA125 value. RESULTS The mean age of the 32 patients was 57±2.8 years. TBRp>1.1, pleural thickening and supradiaphragmatic lymph node were observed significantly more frequently in the MPE than the BPE cases. While no pleural nodules were detected in patients with BPE, they were present in 7 of the patients with MPE. The rates of distinction between the MPE and BPE cases were as follows: the sensitivity of the TBRp value was 95.2% and specificity was 72.7%; the sensitivity of pleural thickness was 80.9% and specificity was 81.8%; the sensitivity of supradiaphragmatic lymph node was 38% and specificity was 90.9%; and the sensitivity of the pleural nodule was 33.3% and specificity was 100%. There were no significant differences between two groups in any other factors. CONCLUSIONS Pleural thickening and TBRp values ascertained through PET/CT may aid the distinction between MPE-BPE, especially in patients with advanced stage OC with a poor general condition, or those who cannot undergo surgery.

18F-FDG PET/CT in ovarian cancer recurrence: Clinical impact, correlation with ceCT and CA-125, and prognostic value. Rev Esp Med Nucl Imagen Mol 2021. [PMID: 33745900 DOI: 10.1016/j.remn.2020.06.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022]
Abstract
AIM To evaluate 18F-FDG-PET/CT for suspected ovarian cancer relapse with negative/inconclusive conventional imaging, or restaging potentially resectable ovarian cancer relapse. MATERIAL AND METHODS Thirty-six cases and 140 locations were studied. PET/CT, ceCT and serum CA-125 was conducted in all cases. Nineteen cases were requested for restaging, 17 for suspected relapse. We compared ceCT and PET/CT, assessed by histopathology or radiological follow-up, calculating sensitivity (S) and positive predictive value (PPV) by cases and lesions. We evaluated the correlation between size, number, uptake of the lesions and CA-125. We conducted survival analysis, using ROC curves to calculate the optimal cut-off of SUVmax for survival prediction. We checked whether PET/CT modify the therapeutic attitude vs. conventional imaging. RESULTS PET/CT and ceCT were concordant in 12 cases: 11 positives (30 lesions), all confirmed. There was 1 FN. In the 24 non-concordant, PET/CT was positive in 19 (97 lesions); ceCT in 21 (59 lesions); 54% of the lesions were concordant. Overall, PET/CT detected 127 lesions, with S = 97% and PPV = 100%. ceCT detected 89 lesions, with S = 61% and PPV = 90%. No significant correlation was found between CA-125 and the other parameters. PET/CT detected 10 positive cases, with normal CA-125. PET/CT modified therapeutic management in 15 cases. Significant differences were found in survival with SUVmax = 11.8 CONCLUSIONS: PET/CT plays an important role in ovarian cancer relapse, with sensitivity and PPV higher than ceCT, modified therapeutic management in up to 42% of cases, and could be a valuable tool for predicting survival.

The Value of PET-CT in Ovarian Epithelial Carcinoma: A Population-Based Study in British Columbia, Canada. J Med Imaging Radiat Sci 2020; 51:264-270. [PMID: 32113969 DOI: 10.1016/j.jmir.2020.01.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 12/18/2019] [Accepted: 01/07/2020] [Indexed: 12/14/2022]
Abstract
INTRODUCTION In epithelial ovarian cancer (EOC), consensus regarding optimal use of PET/CT is lacking. Limited evidence suggests its accuracy in preoperative staging, investigating recurrence and predicting optimal secondary debulking. This study evaluated indications for PET/CT, impact of PET/CT results on EOC management, and its added value over conventional imaging. METHODS Patients with EOC aged 19 years and older who underwent PET/CT at BC Cancer Vancouver between January 2007 and September 2017 were eligible. Medical records were retrospectively reviewed with the following data abstracted: patient demographics, PET/CT indications and results, recent conventional imaging results, and application of PET/CT findings. Basic descriptive analysis was performed to determine most common use of PET/CT and its management impact. RESULTS 257 PET/CTs in 216 patients were eligible. Most PET/CTs (135/257, 52.6%) were performed for suspected disease recurrence/progression. Management after PET/CT changed in 1/3 of cases with the greatest impact seen when assessing suitability in recurrent disease for focal radiotherapy or secondary surgical debulking. For 106/257 cases with recent conventional imaging available, although differences in disease extent were found in ~50%, clinical conclusions drawn were the same in ~75%. DISCUSSION Although PET/CT is most commonly used to investigate suspected recurrence/progression, its impact on management here is low. Greater impact is seen when considering localized therapy in EOC recurrence. When compared with recent conventional imaging, although PET/CT may detect differences in disease extent, clinical conclusions are frequently the same. CONCLUSION Impact of PET/CT on management is greatest in EOC recurrence when considering local therapies, beyond which clinical presentation and conventional imaging may suffice.

Diagnostic value of integrated ¹⁸F-fluoro-2-deoxyglucose positron emission tomography/computed tomography in recurrent epithelial ovarian cancer: accuracy of patient selection for secondary cytoreduction in 134 patients. J Gynecol Oncol 2018; 29:e36. [PMID: 29400023 PMCID: PMC5920220 DOI: 10.3802/jgo.2018.29.e36] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 12/27/2017] [Accepted: 01/26/2018] [Indexed: 11/30/2022] Open
Abstract
Objective The aim of this study was to evaluate the diagnostic value of integrated 18F-fluoro-2-deoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) for suspected recurrence of epithelial ovarian cancer (EOC) with non-disseminated lesions. Methods We retrospectively reviewed the medical records of recurrent EOC patients who underwent secondary cytoreduction from January 2000 to December 2013. A total of 134 patients underwent secondary cytoreduction after imaging with either 18F-FDG-PET/CT or contrast-enhanced computed tomography (CECT). Results In a patient-based analysis of 134 patients, 124 (92.5%) were confirmed to be positive for malignancy. Among 72 patients with suspected non-disseminated recurrence on 18F-FDG-PET/CT, 65 (89.0%) were confirmed to have recurrence, giving 98.5% sensitivity, 87.7% accuracy, and 88.9% positive predictive value (PPV). In the 65 patients with recurrence, residual tumor remained in 14 patients, giving an accuracy of patient selection for secondary cytoreduction of 69.4% (50/72) and it is higher than that of CECT (64.0%). In 169 lesions removed from patients who underwent preoperative 18F-FDG-PET/CT, 135 (79.9%) were confirmed to be positive for malignancy and 124 were accurately detected by 18F-FDG-PET/CT, giving 91.9% sensitivity, 81.1% accuracy, and 85.5% PPV. Foreign body granuloma was found in 33.3% of 21 lesions with false-positive 18F-FDG-PET/CT findings (7/21). The mean preoperative cancer antigen 125 (CA-125) level in false-positive patients was 28.8 U/mL. Conclusion Compared with CECT, 18F-FDG-PET/CT shows higher sensitivity in lesion-based analysis and better accuracy of patient selection for secondary cytoreduction. However, there is still a need for integration of the results of 18F-FDG-PET/CT, CECT, and CA-125 levels to aid treatment planning.

Abstract
Background: The purpose of this study was to evaluate the number of ovarian cancer and primary peritoneal cancer (PPC) progressive disease cases identified via routine follow-up procedures and the corresponding cost throughout a 16-year period at a single medical institution. Methods: Previously undiagnosed epithelial ovarian (n=241), PPC (n=23), and concurrent ovarian and uterine (n=24) cancer patients were treated and then followed via CA-125, imaging (e.g., CT scan, chest X-ray), physical examination and vaginal cytology. Results: In the group of 287 patients, there were 151 cases of disease progression. Serial imaging detected the highest number of progressive disease cases (66 initial and 45 confirmatory diagnoses), but the cost was rather high ($13 454 per patient recurrence), whereas CA-125 testing (74 initial and 20 corroborative diagnoses) was the least expensive ($3924) per recurrent diagnosis. The total cost of surveillance during the 16-year period was nearly $2 400 000. Conclusion: Ultimately, serial imaging and the CA-125 assay detected the highest number of ovarian cancer and PCC progressive disease cases in comparison to physical examination and vaginal cytology, but nevertheless, all of the procedures were conducted at a considerable financial expense.

Abstract
PURPOSE OF REVIEW The utility of positron emission tomography (PET) in gynecologic malignancy has increased rapidly in recent years. This review examines publications in this area. RECENT FINDINGS PET scans are mostly performed using 18-fluorodeoxyglucose (FDG-PET). It is valuable in primary staging of untreated advanced cervical cancer, for posttreatment unexplained tumor marker elevation and restaging of potentially curable recurrent cervical cancer. Its value in early-stage cervical cancer is limited. In ovarian cancer, sequential imaging predicts response to neoadjuvant chemotherapy and survival. It also provides benefits when increases in serum CA 125 or computed tomography/magnetic resonance imaging defined recurrence is noted but biopsy deemed infeasible. A few studies have shown that FDG-PET may facilitate optimal management of endometrial cancer, especially for posttherapy surveillance and after salvage therapy. FDG-PET is potentially useful in selected gestational trophoblastic neoplasia by monitoring response and localizing viable tumors after chemotherapy. Scanty studies have been reported in vulvar and vaginal cancer. The methodology and prospects of using integrated PET/computed tomography in the management of gynecological cancer are discussed. Other PET compounds are briefly introduced. SUMMARY The role of PET or PET/computed tomography has evolved from a diagnostic tool into a potential indicator of response to treatment and prognosis. Evaluating this tool by clinical impact is an attractive end point.
