Abstract
Cervical cancer is a common gynecological malignancy worldwide. Cervical cancer is staged based on the International Federation of Gynecology and Obstetrics (FIGO) classification system, which was revised in 2018 to incorporate radiologic and pathologic data. Imaging plays an important role in pretreatment assessment including initial staging and treatment response assessment of cervical cancer. Accurate determination of tumor size, local extension, and nodal and distant metastases is important for treatment selection and for prognostication. Although local recurrence can be diagnosed by physical examination, imaging plays a critical role in detection and follow-up of local and distant recurrence and subsequent treatment selection. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

[PMID: 38464919 PMCID: PMC10921301 DOI: 10.12998/wjcc.v12.i6.1182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 01/05/2024] [Accepted: 01/29/2024] [Indexed: 02/20/2024] Open
Abstract
BACKGROUND Lung cancer (LC) is the leading cause of malignancy-related deaths worldwide. The most common sites of metastasis include the nervous system, bone, liver, respiratory system, and adrenal glands. LC metastasis in the parotid gland is very rare, and its diagnosis presents a challenge. Here, we report a case of parotid metastasis in primary LC. CASE SUMMARY The patient was a 74-year-old male who was discovered to have bilateral facial asymmetry inadvertently two years ago. The right earlobe was slightly swollen and without pain or numbness. Computed tomography (CT) examination showed bilateral lung space-occupying lesions. Pulmonary biopsy was performed and revealed adenocarcinoma (right-upper-lung nodule tissue). Positron emission tomography-CT examination showed: (1) Two hypermetabolic nodules in the right upper lobe of the lung, enlarged hypermetabolic lymph nodes in the right hilar and mediastinum, and malignant space-occupying lesion in the right upper lobe of the lung and possible metastasis to the right hilar and mediastinal lymph nodes; and (2) multiple hypermetabolic nodules in bilateral parotid glands. Parotid puncture biopsy was performed considering lung adenocarcinoma metastasis. Gene detection of lung biopsy specimens revealed an EGFR gene 21 exon L858R mutation. CONCLUSION This case report highlights the challenging diagnosis of parotid metastasis in LC given its rare nature. Such lesions should be differentiated from primary tumors of the parotid gland. Simple radiological imaging is unreliable, and puncture biopsy is needed for final diagnosis of this condition.

Prediction of Patient Outcomes in Locally Advanced Cervical Carcinoma Following Chemoradiotherapy-Comparative Effectiveness of Magnetic Resonance Imaging and 2-Deoxy-2-[ 18F]fluoro-D-glucose Imaging. Cancers (Basel) 2024; 16:476. [PMID: 38339229 PMCID: PMC10854890 DOI: 10.3390/cancers16030476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 01/16/2024] [Accepted: 01/18/2024] [Indexed: 02/12/2024] Open
Abstract
PURPOSE To evaluate the utility and comparative effectiveness of three five-point qualitative scoring systems for assessing response on PET-CT and MRI imaging individually and in combination, following curative-intent chemoradiotherapy (CRT) in locally advanced cervical cancer (LACC). Their performance in the prediction of subsequent patient outcomes was also assessed; Methods: Ninety-seven patients with histologically confirmed LACC treated with CRT using standard institutional protocols at a single centre who underwent PET-CT and MRI at staging and post treatment were identified retrospectively from an institutional database. The post-CRT imaging studies were independently reviewed, and response assessed using five-point scoring tools for T2WI, DWI, and FDG PET-CT. Patient characteristics, staging, treatment, and follow-up details including progression-free survival (PFS) and overall survival (OS) outcomes were collected. To compare diagnostic performance metrics, a two-proportion z-test was employed. A Kaplan-Meier analysis (Mantel-Cox log-rank) was performed. RESULTS The T2WI (p < 0.00001, p < 0.00001) and DWI response scores (p < 0.00001, p = 0.0002) had higher specificity and accuracy than the PET-CT. The T2WI score had the highest positive predictive value (PPV), while the negative predictive value (NPV) was consistent across modalities. The combined MR scores maintained high NPV, PPV, specificity, and sensitivity, and the PET/MR consensus scores showed superior diagnostic accuracy and specificity compared to the PET-CT score alone (p = 0.02926, p = 0.0083). The Kaplan-Meier analysis revealed significant differences in the PFS based on the T2WI (p < 0.001), DWI (p < 0.001), combined MR (p = 0.003), and PET-CT/MR consensus scores (p < 0.001) and in the OS for the T2WI (p < 0.001), DWI (p < 0.001), and combined MR scores (p = 0.031) between responders and non-responders. CONCLUSION Post-CRT response assessment using qualitative MR scoring and/or consensus PET-CT and MRI scoring was a better predictor of outcome compared to PET-CT assessment alone. This requires validation in a larger prospective study but offers the potential to help stratify patient follow-up in the future.

Abstract
Carcinoma cervix spread to locoregional lymph nodes. Distance metastases are uncommon and occur through hematogenous routes in advanced stages. The common sites include bone and lungs. Another organ involvement is uncommon. Computed tomography (CT) and magnetic resonance imaging have a crucial role in diagnosing local and distant metastasis. 18F-fluorodeoxyglucose positron emission tomography/CT (18F-FDG PET/CT) is a sensitive molecular imaging modality for various cancers, including gynecological ones. We present a case of recurrent cervical carcinoma presented with cervical mass and several rare visceral metastases. 18F-FDG PET/CT is a whole-body modality that accurately localized all lesions in a single study.

Abstract
It has been reported that extramammary malignant tumors metastasize to the breast, but cervical cancer metastasis to the breast is very rare. At present, there are only dozens of reports about cervical cancer metastasis to breast in the world. It is difficult to distinguish between primary breast cancer and metastatic breast cancer. We report a 44-year-old woman who underwent surgery, chemotherapy, and radiotherapy for cervical cancer 5 years ago. Then, she was hospitalized for finding a left breast mass measured 2.9 × 2.7 cm in chest CT. Pathological examination combined with immunohistochemical staining showed that the mass came from the cervix. Then, the patient received systematic chemotherapy and interstitial brachytherapy (IB) for the breast mass and got a great result. Cervical cancer rarely metastasizes to the breast. In this case, we confirmed the diagnosis of breast mass by histopathological examination and immunohistochemistry. IB achieved a good result in the treatment of the breast mass. We hope to provide reference of prognosis and treatment when facing this situation by presenting this case.

Abstract
The prognosis of patients with liver metastasis of cervical cancer is poor with an extremely short survival period, and there have been no reports of cervical cancer complicated by portal vein tumor thrombosis (PVTT). We report a case of cervical cancer developing liver metastasis with PVTT. A 49-year-old woman developed liver metastasis from cervical cancer with PVTT. The primary tumor was locally controlled with multidisciplinary treatment, including systemic therapy, surgical resection, and radiation. However, her follow-up abdominal computed tomography results showed two irregular tumors in the liver's segments 2 and 6. From the latter lesion, a low-density filling defect extended to the posterior branch of the portal vein, suggesting PVTT. Hepatectomy of the two metastases was performed to prevent portal vein obstruction during subsequent chemotherapy. Pathological analysis revealed metastatic squamous cell carcinoma from cervical cancer that developed a tumor thrombus at the posterior branch of the portal vein. The patient received adjuvant chemotherapy, but died 10 months after surgery for recurrent liver metastasis. We present the first case of liver resection for liver metastasis from cervical cancer with PVTT. Although cervical cancer with PVTT is associated with a poor prognosis, surgical resection is a feasible option for preventing portal vein obstruction during subsequent chemotherapy.

Abstract
To compare the clinical application value of positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) in the diagnosis of cervical cancer lymph node metastasis. We searched PubMed and other databases for the studies comparing the use of PET-CT and MRI for the diagnosis of cervical cancer lymph node metastasis up to January 20, 2021. We strictly followed the inclusion and exclusion criteria to screen the literature and extract the data. Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 tool was used for quality evaluation of included studies, and Revman 5.3 and Stata 15.0 software were used for evaluating heterogeneity, synthesize sensitivity (SEN), specificity (SPE), positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio (DOR), and the area under the curve (AUC) and comparing the pretest and posttest probabilities. Finally, 11 studies were included for meta-analysis. The synthesized results indicated that the SEN value of PET-CT was 0.65 (0.60 ~ 0.69) and SPE was 0.93 (0.91 ~ 0.94), and the SEN value of MRI was 0.58 (0.54 ~ 0.63) and SPE was 0.91 (0.90 ~ 0.92). AUC of PET-CT was 0.824, which was significantly higher than that of MRI (AUC = 0.702; p < .05). The subgroup analysis showed that the AUC value of the study based on study design and use of blinding methods was not statistically significant (all p > .05). There was no obvious publication bias in the synthesized analysis of the diagnostic value of PET-CT and MRI (all p > .05). HIGHLIGHTS: To compare positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) in diagnosis of cervical cancer lymph node metastasis. Synthesize sensitivity value of PET-CT was comparable with that of MRI. Area under the curve of PET-CT was significantly higher than that of MRI. There was no obvious publication bias in synthesized analysis.

Abstract
The purpose of this study is to review the clinical characteristics, treatment modalities, and potential contributing and prognostic factors of bone metastases from gynecological cancers (GCs). A systematic literature search on PubMed, Scopus, Web of Science Core Collection and Cochrane Central Register of Controlled Trials databases was conducted. Thirty-one studies, all retrospective, were included in this review, for a total of 2880 patients with GC bone metastases. Primary tumors leading to bone metastases included endometrial cancer (EC), cervical cancer (CC), ovarian cancer (OC), uterine sarcoma (US) and vulvar cancer (VuC), mainly with an International Federation of Gynecology and Obstetrics (FIGO) Stage of III and IV. The main bone metastatic lesion site was the vertebral column, followed by the pelvic bone and lower extremity bones. The median survival rate after bone metastases diagnosis ranged from 3.0 to 45 months. The most frequent treatments were palliative and included radiotherapy and chemotherapy, followed by surgery. The findings of this review give a first dataset for a greater understanding of GC bone metastases that could help clinicians move toward a more “personalized” and thus more effective patient management.

Abstract
OBJECTIVE To investigate the value of MRI after ultrasonic gel vagina filling in the staging of early-stage cervical cancer. METHODS A total of 158 patients with cervical cancer who underwent MRI examination after their cervical cancer diagnosis was confirmed by cervical biopsy were prospectively enrolled. Routine MRI examination was performed first, followed by another MRI examination after vaginal filling with ultrasound gel. Two physicians used a double-blind method to determine the staging of cervical cancer based on the MRI images before and after vaginal filling of ultrasound gel. Results of the postoperative pathology analysis were used as the golden standard. The positive predictive value and negative predictive value for stage Ⅱa cases of the two examinations of the same patient were compared, and the sensitivity, specificity and accuracy in identifying stage Ⅱa cervical cancer were compared. RESULTS Two physicians used the double blind method to determine the staging of cervical cancer based on conventional MRI images, achieving moderate consistency ( κ=0.680). However, for the staging of cervical cancer with MRI images after vaginal filling of ultrasound gel, the two physicians achieved highly consistent results ( κ=0.932). Regarding identifying stage Ⅱa cervical cancer, the positive predictive value of conventional MRI was 66.67%, the negative predictive value was 76.74%, and the sensitivity, specificity and accuracy were 70.59%, 73.33% and 72.15%, respectively. The positive predictive value of MRI after vaginal filling of ultrasound gel was 90.91%, the negative predictive value was 91.3%, and the sensitivity, specificity and accuracy were 88.24%, 93.33% and 91.14%, respectively. The sensitivity, specificity and accuracy of the two methods were compared and the difference was statistical significant ( P<0.05). CONCLUSION MRI examination after ultrasound gel vaginal filling has better diagnostic value for identifying stage Ⅱa cervical cancer. The method is simple and easy to do, and can be used in routine MRI examination of cervical cancer.

Diagnostic Accuracy of 18F-FDG-PET/CT and MRI in Predicting the Tumor Response in Locally Advanced Cervical Carcinoma Treated by Chemoradiotherapy: A Meta-Analysis. CONTRAST MEDIA & MOLECULAR IMAGING 2021; 2021:8874990. [PMID: 33746650 PMCID: PMC7943297 DOI: 10.1155/2021/8874990] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 01/17/2021] [Accepted: 02/20/2021] [Indexed: 01/19/2023]
Abstract
Objective The aim of this meta-analysis was to compare the diagnostic accuracy of 18F-FDG-PET/CT and MRI in predicting the tumor response in locally advanced cervical carcinoma (LACC) treated by chemoradiotherapy (CRT). Method This meta-analysis has been performed according to PRISMA guidelines. Systematic searches were conducted using PubMed and Embase databases for articles published from January 1, 2010, to January 1, 2020. By using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool, the reviewers assessed the methodological quality scores of the selected studies. We analyzed the sensitivity, specificity, and accuracy of two diagnostic methods using Meta-DiSc 1.4 and Stata 15. Results An overall of 15 studies including 1132 patients were included. Sensitivities of PET/CT and MRI were 83.5% and 82.7%, while the corresponding rates for specificities were 77.8% and 68.4%, respectively. The DOR, PLR, and NLR for MRI were 15.140, 2.92, and 22.6. PET/CT had a DOR of 25.21. The PLR and NLR for PET/CT were 4.13 and 0.215, respectively. The diagnostic sensitivity and specificity of PET/CT for the detection of residual tumor were 86% and 95%, respectively. The corresponding rates for MRI were 73% and 96%, respectively. The diagnostic sensitivity and specificity of PET/CT for the detection of tumor metastases were 97% and 99%, while the corresponding rates for MRI were 31% and 98%, respectively. Conclusion 18F-FDG PET/CT seemed to have a better overall diagnostic accuracy in the evaluation of treatment response to chemoradiotherapy in LACC patients. MRI showed a really poor sensitivity in the detection of metastases, and PET/CT performed significantly better. However, the difference between these two methods in the detection of residual disease was not significant. More studies are needed to be conducted in order to approve that 18F-FDG PET/CT can be a standard option to assess the treatment response.

Abstract
To determine the location patterns of distant metastases at initial staging and outcomes of ovarian, uterine, and cervical cancer patients. Data were obtained from the SEER database from 2010 to 2015. Analyses were performed using Kaplan-Meier and multivariate Cox proportional hazard methods. Of 3035 patients (median age: 63, range: 17-95) with stage IV gynecologic cancer, ovarian, uterine, and cervical cancers were present in 42%, 40%, and 18% of the cohort. The proportion of lung, liver, bone and brain metastases were identified in 38%, 57%, 4%, and 1% of ovarian cancer patients, 62%, 22%, 13%, and 3% of uterine cancer patients, and 59%, 16%, 23%, and 2% of cervical cancer patients, respectively. The 5-year disease-specific survival for all patients was 19%. Those with liver metastases had survival rates of 26% compared to 15% for lung, 13% for bone, and 6% for brain (p < 0.0001). Patients with ovarian, uterine, and cervical cancers had survival rates of 28%, 12%, and 12%, respectively (p < 0.0001). On multivariate analysis, brain metastasis (HR = 1.64, 95% CI 1.21-2.22, p < 0.01), uterine (HR = 1.77, 95 CI 1.56-2.02, p < 0.0001) and cervical (HR = 1.35, 95% CI 1.11-1.63, p < 0.01) cancers, and lack of insurance (HR = 1.41, 95% CI 1.16-1.73, p < 0.001) were independent predictors for poorer survival. Age, year, region, and race did not affect prognosis. Stage IV ovarian cancer most frequently metastasizes to the liver, whereas uterine and cervical cancers spread more to the lung. Overall, these patients have poor prognosis, particularly those with uterine or cervical primary disease or brain metastases.

Abstract
FDG-PET/CT has an established role in the initial staging of locally advanced cervical cancers, particularly in evaluation of nodal disease and distant metastases. It is common practice to perform FDG-PET/CT 3 months postcompletion of chemoradiotherapy as it can predict outcome and be used to tailor management, including adjuvant therapy and follow-up. It is also routinely used prior to pelvic exenterative surgery to ensure there is no disease outside the pelvis. There is growing evidence that FDG-PET-derived parameters are prognostic and could potentially be used to tailor therapy. This review outlines the use of FDG-PET/CT imaging in cervical cancer.
