Abstract
OBJECTIVE Magnetic resonance imaging (MRI) can be used to assess parametrial invasion (PMI) in cervical cancer. Discordance between MRI findings and International Federation of Gynecology and Obstetrics (FIGO) staging is not uncommon because FIGO staging depends on physical examination. The purpose of this study was to retrospectively evaluate the long-term outcomes of MRI stage IIB cervical cancer. METHODS A total of 312 patients with MRI stage IIB cervical cancer were retrospectively found between 2002 and 2011. Of these patients, 171 (group 1) were FIGO stage IIB cervical cancers and 141 (group 2) were MRI stage IIB cervical cancers that were negative PMI on physical examination. Group 1 was treated with chemotherapy and/or radiation therapy, and group 2 was treated with radical hysterectomy and lymph node dissection. The FIGO stages and pathologic findings of group 2 were recorded. Groups 1 and 2 were compared regarding 5-year overall survival rate. RESULTS The FIGO stages of group 2 were IB1 in 51 (36.2%), IB2 in 28 (19.9%), and IIA in 62 (44%), whereas those of group 1 were all IIB. Group 2 showed lymphovascular space invasion in 71 (50.4%), lymph node metastasis in 48 (34.0%), PMI in 46 (32.6%), and vagina invasion in 9 (6.4%). Five-year overall survival rates of groups 1 and 2 were 73.7% and 84.5%, respectively (P = 0.013). CONCLUSIONS Magnetic resonance imaging stage IIB cervical cancers with negative PMI on physical examination should be surgically treated because of better survival rate than FIGO stage IIB cervical cancers.

Abstract
(Objectives) For the staging of cervical cancer, we investigated the relationship between computed tomography/magnetic resonance imaging (CT/MRI) and cystoscopy and evaluated the need for cystoscopy to diagnose bladder invasion resulting from cervical cancer. (Patients and Methods) We retrospectively reviewed the patients who underwent cystoscopy because of a diagnosis of bladder invasion of cervical cancer from April 2012 to March 2017 in our hospital. A total of 217 women (median age 53 years old) underwent cystoscopy. We also reviewed whether or not there were findings showing bladder wall infiltration on CT/MRI and cystoscopy. (Results) CT was performed in all cases, and MRI was performed in 216 cases. Seventy cases were judged to have possible bladder infiltration by CT, and 35 were judged to have possible bladder infiltration by MRI. In cystoscopy, 24 cases were reported to have "suspicion of bladder invasion" by urologists, but only 12 cases had bladder mucosal findings with "ridges and furrows" (defined as bladder infiltration without a bladder biopsy in this study). The sensitivity and negative predictive values of CT/MRI were both 100%. Only one case underwent a bladder biopsy, and the histological diagnosis was cystitis. (Conclusions) The findings of our investigation suggested that cystoscopy is not required when there were no obvious findings of bladder invasion by CT/MRI at the clinical staging of cervical cancer.

Abstract
OBJECTIVES To assess the value of new magnetic resonance imaging (MRI) techniques in cervical cancer. METHODS We searched PubMed and MEDLINE and reviewed articles published from 1990 to 2016 to identify studies that used MRI techniques, such as diffusion weighted imaging (DWI), intravoxel incoherent motion (IVIM) and dynamic contrast enhancement (DCE) MRI, to assess parametric invasion, to detect lymph node metastases, tumour subtype and grading, and to detect and predict tumour recurrence. RESULTS Seventy-nine studies were included. The additional use of DWI improved the accuracy and sensitivity of the evaluation of parametrial extension. Most studies reported improved detection of nodal metastases. Functional MRI techniques have the potential to assess tumour subtypes and tumour grade differentiation, and they showed additional value in detecting and predicting treatment response. Limitations included a lack of technical standardisation, which limits reproducibility. CONCLUSIONS New advanced MRI techniques allow improved analysis of tumour biology and the tumour microenvironment. They can improve TNM staging and show promise for tumour classification and for assessing the risk of tumour recurrence. They may be helpful for developing optimised and personalised therapy for patients with cervical cancer. TEACHING POINTS • Conventional MRI plays a key role in the evaluation of cervical cancer. • DWI improves tumour delineation and detection of nodal metastases in cervical cancer. • Advanced MRI techniques show promise regarding histological grading and subtype differentiation. • Tumour ADC is a potential biomarker for response to treatment.

Abstract
Historically, cancer treatment has emphasized measures for the "cure" regardless of the long-term consequences. Advances in cancer detection and treatment have resulted in improved outcomes bringing to the fore various quality of life considerations including future fertility. For many young cancer patients, fertility preservation is now an integral component of clinical decision-making and treatment design. Optimal fertility-sparing options for young patients with gynecologic cancer are influenced by patient age, primary cancer, treatment regimens, and patient preferences. Possible approaches include embryo or oocyte cryopreservation, ovarian transposition, conservative surgery, and conservative medical treatment to delay radical surgery. These may be used alone or in combination to maximize fertility preservation. Awareness of the various fertility-sparing options, eligibility criteria, and the central role of magnetic resonance imaging in the proper selection of patients will enable radiologists to produce complete clinically relevant imaging reports and serve as effective consultants to referring clinicians. Knowledge of the potential imaging pitfalls is essential to avoid misinterpretation and guide appropriate management.

Abstract
Gynecologic cancer is a heterogeneous group of diseases both functionally and morphologically. Today, PET coupled with computed tomography (PET/CT) or PET/MR imaging play a central role in the precision medicine algorithm of patients with gynecologic malignancy. In particular, PET/CT and PET/MR imaging are molecular imaging techniques that not only are useful tools for initial staging and restaging but provide anatomofunctional insight and can serve as predictive and prognostic biomarkers of response in patients with gynecologic malignancy.

Abstract
PURPOSE Biliary stents may cause susceptibility artifacts, gradient-induced artifacts, and radio frequency (RF) induced artifacts on magnetic resonance images, which can hinder accurate target volume delineation in radiotherapy. In this study, the authors investigated and quantified the magnitude of these artifacts for stents of different materials. METHODS Eight biliary stents made of nitinol, platinum-cored nitinol, stainless steel, or polyethylene from seven vendors, with different lengths (57-98 mm) and diameters (3.0-11.7 mm), were placed in a phantom. To quantify the susceptibility artifacts sequence-independently, ΔB0-maps and T2∗-maps were acquired at 1.5 and 3 T. To study the effect of the gradient-induced artifacts at 3 T, signal decay in images obtained with maximum readout gradient-induced artifacts was compared to signal decay in reference scans. To quantify the RF induced artifacts at 3 T, B1-maps were acquired. Finally, ΔB0-maps and T2∗-maps were acquired at 3 T of two pancreatic cancer patients who had received platinum-cored nitinol biliary stents. RESULTS Outside the stent, susceptibility artifacts dominated the other artifacts. The stainless steel stent produced the largest susceptibility artifacts. The other stents caused decreased T2∗ up to 5.1 mm (1.5 T) and 8.5 mm (3 T) from the edge of the stent. For sequences with a higher bandwidth per voxel (1.5 T: BWvox > 275 Hz/voxel; 3 T: BWvox > 500 Hz/voxel), the B0-related susceptibility artifacts were negligible (<0.2 voxels). The polyethylene stent showed no artifacts. In vivo, the changes in B0 and T2∗ induced by the stent were larger than typical variations in B0 and T2∗ induced by anatomy when the stent was at an angle of 30° with the main magnetic field. CONCLUSIONS Susceptibility artifacts were dominating over the other artifacts. The magnitudes of the susceptibility artifacts were determined sequence-independently. This method allows to include additional safety margins that ensure target irradiation.

Abstract
GOAL The goal of this study was the determination of the effects in treatment of early stage ( MATERIAL AND METHODS The study was a prospective, comparative, analytical, and observational and included 74 patients with cervical cancer (PH confirmed). All 74 patients have initially gone through the pre-therapeutic MRI to determine the tumour FIGO stage. At a renewal of the initial MRI findings, patients were divided into two study groups: group A and group B. Group A consisted from 39 patients with early-stage cervical carcinoma ( RESULTS An analysis of treatment outcomes in group A showed that most patients had no local recurrence or residuum disease in 89.7%, while local recurrence was observed in only 10.3% cases. An analysis of treatment outcomes in group B showed that most patients had complete regression after local chemoradiotherapy in 68.8%, while 25.7% of patients had local progression of the disease, while the 5.7% cases recorded partial local tumour regression(p<0.05). It has been shown that a complete local regression was more frequent in the case of squamous cell carcinoma in 74.2% vs 25% in adenocarcinoma cases. Also local and partial regression was observed more frequently in the case of squamous cell carcinoma in 6.5% compared to 0% in adenocarcinoma, while progression was more common in adenocarcinoma at 75% compared to 19.4% for squamous cell (p<0.05). MRI results showed positive outcome of treatment group A and B in our study, showed a statistically significant difference in favour of group A (89.7%) compared to group B 68.8% (p<0.05).

Abstract
Imaging plays a central role in the evaluation of patients with cervical cancer and helps guide treatment decisions. The purpose of this pictorial review is to describe magnetic resonance (MR) imaging and positron emission tomography (PET)/computed tomography (CT) assessment of cervical cancer, including indications for imaging, important findings that may result in management change, as well as limitations of both modalities. The International Federation of Gynecology and Obstetrics cervical cancer staging system does not officially include imaging; however, the organization endorses the use of MR imaging and PET/CT in the management of patients with cervical cancer where these modalities are available. MR imaging provides the best visualization of the primary tumor and extent of soft tissue disease. PET/CT is recommended for assessment of nodal involvement, as well as distant metastases. Both MR imaging and PET/CT are used to follow patients post-treatment to assess for recurrence. This review focuses on the current MR imaging and PET/CT protocols, the utility of these modalities in assessing primary tumors and recurrences, with emphasis on imaging findings which change management and on imaging pitfalls to avoid. It is important to be familiar with the MR imaging and PET/CT appearance of the primary tumor and metastasis, as well as the imaging pitfalls, so that an accurate assessment of disease burden is made prior to treatment.

Abstract
Uterine cervical cancer still remains an important socioeconomic issue because it largely affects women of reproductive age. Prognosis is highly depended on extent of the disease at diagnosis and, therefore, accurate staging is crucial for optimal management. Cervical cancer is clinically staged, according to International Federation of Gynecology and Obstetrics guidelines, but, currently, there is increased use of cross sectional imaging modalities [computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-CT (PET-CT)] for the study of important prognostic factors like tumor size, parametrial invasion, endocervical extension, pelvic side wall or adjacent/distal organs involvement and lymph node status. Imaging indications also include cervical cancer follow-up, evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation. The preferred imaging method for local cervical cancer evaluation is MRI; CT is equally effective for evaluation of extrauterine spread of the disease. PET-CT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes. The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma.

Abstract
OBJECTIVE Magnetic resonance imaging (MRI) is useful for staging endometrial cancer. The treatment and prognosis of MRI-invisible endometrial cancer remain unclear. The purpose of this study was to retrospectively evaluate the long-term outcomes of patients with MRI-invisible endometrial cancer. METHODS Between February 1995 and December 2011, we reviewed the medical records of 433 patients with endometrial cancer, which was staged IA on MRI. Of these patients, 89 had MRI-invisible cancer and 344 had MRI-visible cancer. Both cancers were treated with simple hysterectomy with or without lymph node dissection according to the surgeon's decision. Both cancers were compared regarding pathologic findings, recurrence rates, and survival rates. RESULTS The median sizes of MRI-invisible and MRI-visible cancers were 4 mm (0 to 40 mm) and 20 mm (0 to 89 mm), respectively (p<0.001). Myometrial invasion of these groups were detected in 20.2% (18/89) and 56.7% (195/344), respectively (p<0.001). Lymphadenectomy and follow-up imaging revealed no lymph node metastasis in patients with MRI-invisible cancers, while those revealed in 4.7% (16/344) of patients with MRI-visible cancers (p=0.052). The recurrence rates of MRI-invisible and MRI-visible cancers were 1.1% (1/89) and 7.8% (27/344), respectively (p=0.026). The recurrence-free survival rates of these groups were 98.9% (88/89) and 91.6% (315/344), respectively (p=0.022). CONCLUSION MRI-invisible endometrial cancer can be treated with less invasive surgery because of its lower tumor burden and better prognosis. This cancer may not require lymphadenectomy because of no metastasis or recurrence in lymph nodes.

Downey K, Attygalle AD, Morgan VA, Giles SL, MacDonald A, Davis M, Ind TEJ, Shepherd JH, deSouza NM. Comparison of optimised endovaginal vs external array coil T2-weighted and diffusion-weighted imaging techniques for detecting suspected early stage (IA/IB1) uterine cervical cancer. Eur Radiol 2016; 26:941-50. [PMID: 26162579 PMCID: PMC4778155 DOI: 10.1007/s00330-015-3899-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2015] [Revised: 06/09/2015] [Accepted: 06/22/2015] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To compare sensitivity and specificity of endovaginal versus external-array coil T2-W and T2-W + DWI for detecting and staging small cervical tumours. METHODS Optimised endovaginal and external array coil MRI at 3.0-T was done prospectively in 48 consecutive patients with stage Ia/Ib1 cervical cancer. Sensitivity/specificity for detecting tumour and parametrial extension against histopathology for a reading radiologist were determined on coronal T2-W and T2W + DW images. An independent radiologist also scored T2-W images without and with addition of DWI for the external-array and endovaginal coils on separate occasions >2 weeks apart. Cohen's kappa assessed inter- and intra-observer agreement. RESULTS Median tumour volume in 19/38 cases positive on subsequent histology was 1.75 cm(3). Sensitivity, specificity, PPV, NPV were: reading radiologist 91.3 %, 89.5 %, 91.3 %, 89.5 %, respectively; independent radiologist T2-W 82.6 %, 73.7 %, 79.1 %, 77.8 % for endovaginal, 73.9 %, 89.5 %, 89.5 %, 73.9 % for external-array coil. Adding DWI improved sensitivity and specificity of endovaginal imaging (78.2 %, 89.5 %); adding DWI to external-array imaging improved specificity (94.7 %) but reduced sensitivity (66.7 %). Inter- and intra-observer agreement on T2-W + DWI was good (kappa = 0.67 and 0.62, respectively). CONCLUSION Endovaginal coil T2-W MRI is more sensitive than external-array coil for detecting tumours <2 cm(3); adding DWI improves specificity of endovaginal imaging but reduces sensitivity of external-array imaging. KEY POINTS • Endovaginal more accurate than external-array T2-W MRI for detecting small cervical cancers. • Addition of DWI improves sensitivity and specificity of endovaginal T2-W imaging. • Addition of DWI substantially reduces sensitivity of external-array T2-W imaging.

Abstract
AIM To determine the ability of magnetic resonance imaging (MRI) in detecting tumour-free margins from the internal os (IO). MATERIALS AND METHODS A database search yielded 79 women with early-stage cervical cancer who underwent radical hysterectomy and preoperative MRI. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MRI in assessment of ≤5 and >5 mm IO involvement were calculated with histopathological surgical specimen findings considered to be the reference standard. A main and subset analysis was performed. The subset analysis included only those patients who would have been considered for radical trachelectomy. RESULTS For predicting a distance between the tumour and the IO of ≤5 mm, MRI had a sensitivity of 73%, a specificity of 98.3%, a PPV of 95%, a NPV of 88.1%, and an accuracy of 89.8% for the main analysis, and sensitivity of 81.8%, a specificity of 93.2% a PPV of 69.2% a NPV of 96.5% and an accuracy of 91.4% for the subset analysis. CONCLUSION MRI has high specificity, NPV, and accuracy in detecting tumour from the IO, making MRI suitable for treatment planning in patients desiring trachelectomy to preserve fertility.

Abstract
Cervical cancer is a leading cause of mortality in women worldwide. Staging and management of cervical cancer has for many years been based on clinical exam and basic imaging such as intravenous pyelogram and x-ray. Unfortunately, despite advances in radiotherapy and the inclusion of chemotherapy in the standard plan for locally advanced disease, local control has been unsatisfactory. This situation has changed only recently with the increasing implementation of magnetic resonance image (MRI)-guided brachytherapy. The purpose of this article is therefore to provide an overview of the benefits of MRI in the evaluation and management of cervical cancer for both external beam radiotherapy and brachytherapy and to provide a practical approach if access to MRI is limited.

Abstract
PURPOSE The aim of this prospective study was to compare the diagnostic accuracy of transvaginal sonography (TVS) with that of MRI in the local staging of cervical cancer. METHODS All consecutive patients diagnosed with invasive carcinoma of the cervix over a 3-year period underwent MRI of the pelvis and TVS according to a standardized protocol. RESULTS In total, 46 patients were recruited to the study. We found a strong correlation between MRI and TVS in the assessment of tumor volume in both early-stage and advanced-stage disease (p < 0.0001). Both MRI and TVS had a sensitivity of 80%, a specificity of 50%, and a diagnostic accuracy of 63.6% for the detection of stromal invasion in early-stage disease. For the detection of parametrial invasion, we found sensitivity rates of 40% for MRI and 86% for TVS; specificity rates of 78.8% for MRI and 20% for TVS; and diagnostic accuracy rates of 89% for MRI and 78.7% for TVS. A matched-sample analysis revealed that there was no statistically significant difference between MRI and TVS in the assessment of stromal or parametrial invasion (p = 0.06). CONCLUSIONS TVS performed by a dedicated gynecologic radiologist is a feasible and economic imaging modality with a diagnostic accuracy comparable to that of MRI. It may be used as an adjunct to MRI for the local staging of invasive cervical cancer or to allow for rapid and confident triage of patients into operative and nonoperative categories for management in the gynecologic outpatient setting.

A Comparison of Lumpectomy Cavity Delineations Between Use of Magnetic Resonance Imaging and Computed Tomography Acquired With Patient in Prone Position for Radiation Therapy Planning of Breast Cancer.

Abstract
PURPOSE To compare lumpectomy cavity (LC) and planning target volume (PTV) delineated with the use of magnetic resonance imaging (MRI) and computed tomography (CT) and to examine the possibility of replacing CT with MRI for radiation therapy (RT) planning for breast cancer. METHODS AND MATERIALS MRI and CT data were acquired for 15 patients with early-stage breast cancer undergoing lumpectomy during RT simulation in prone positions, the same as their RT treatment positions. The LCs were delineated manually on both CT (LC-CT) and MRI acquired with 4 sequences: T1, T2, STIR, and DCE. Various PTVs were created by expanding a 15-mm margin from the corresponding LCs and from the union of the LCs for the 4 MRI sequences (PTV-MRI). Differences were measured in terms of cavity visualization score (CVS) and dice coefficient (DC). RESULTS The mean CVSs for T1, T2, STIR, DCE, and CT defined LCs were 3.47, 3.47, 3.87, 3.50. and 2.60, respectively, implying that the LC is mostly visible with a STIR sequence. The mean reductions of LCs from those for CT were 22%, 43%, 36%, and 17% for T1, T2, STIR, and DCE, respectively. In 14 of 15 cases, MRI (union of T1, T2, STIR, and DCE) defined LC included extra regions that would not be visible from CT. The DCs between CT and MRI (union of T1, T2, STIR, and DCE) defined volumes were 0.65 ± 0.20 for LCs and 0.85 ± 0.06 for PTVs. There was no obvious difference between the volumes of PTV-MRI and PTV-CT, and the average PTV-STIR/PTV-CT volume ratio was 0.83 ± 0.23. CONCLUSIONS The use of MRI improves the visibility of LC in comparison with CT. The volumes of LC and PTV generated based on a MRI sequence are substantially smaller than those based on CT, and the PTV-MRI volumes, defined by the union of T1, T2, STIR, and DCE, were comparable with those of PTV-CT for most of the cases studied.

Abstract
The focus of this article is radiation therapy for gynecologic cancers, with emphasis on imaging-based treatment planning and delivery. For the various gynecologic cancers, radiation oncologists rely on essential clinical information to triage treatment options, and various imaging studies are performed for treatment planning and radiation therapy delivery. A practical approach is provided to help radiologists tailor their reports for the needs of their radiation oncology and gynecologic oncology colleagues, to optimize multidisciplinary care for patients with gynecologic cancer. Template radiology reports are proposed to address the specific information needs of oncologists at each phase-before, during, and after treatment. Fueled by the rapid progress in engineering and computer sciences during the past 2 decades, remarkable advances have been made in anatomic, functional, and molecular imaging and in radiation treatment planning and delivery in patients with gynecologic cancer. Radiation therapy has evolved from a nontargeted approach to a precisely targeted, highly conformal treatment modality, to further improve treatment outcomes and reduce morbidity. High-quality imaging has become essential for staging of the disease, delineation of tumor extent for treatment planning and delivery, and monitoring therapy response. Anatomic and functional imaging has also been shown to provide prognostic information that allows clinicians to tailor therapy on the basis of personalized patient information. This field is an area of active research, and future clinical trials are warranted to validate preliminary results in the field.

Abstract
OBJECTIVE This study aimed to investigate the applied value of F-fluoro-2-dexoxyglucose (F-FDG) PET/computed tomography (CT) and MRI in detecting lymph-node metastasis in early-stage cervical cancer. MATERIALS AND METHODS A retrospective study was performed on 87 early-stage cervical cancer patients evaluated with PET/CT and pelvic MRI before surgery. Histopathological evaluation of lymph nodes served as the diagnostic standard. F-FDG PET/CT and MRI images were analyzed and correlated with histopathological findings. RESULTS The overall node-based sensitivity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of PET/CT were 91% (61/67), 78.2% (61/78), 99.4% (1079/1085), and 98% (1140/1163), respectively, which were higher than the corresponding values of MRI, at 37.3% (25/67), 61% (25/41), 96.3% (1080/1122), and 95% (1105/1163) (P<0.034). The difference in diagnostic efficacy for identifying node-based metastases between PET/CT and MRI was significant (PET/CT vs. MRI, 0.719 vs. 0.587, P=0.017). Meanwhile, the overall patient-based sensitivity, PPV, NPV, and accuracy of PET/CT were 100% (34/34), 87.2% (34/39), 100% (48/48), and 94.3% (82/87), respectively, whereas the corresponding MRI values were 44% (15/34), 65% (15/23),74% (45/61), and 69% (60/87) (P<0.04). The difference in diagnostic efficacy for identifying patient-based metastases between PET/CT and MRI was significant (PET/CT vs. MRI, 0.974 vs. 0.705, P<0.001). CONCLUSION PET/CT has been proven to be valuable in detecting lymph-node metastases. Compared with MRI, PET/CT has higher sensitivity, PPV, NPV, and accuracy in patients with early-stage cervical cancer for detecting lymphatic metastases.

The role of PET-CT in radiotherapy planning of solid tumours. Radiol Oncol 2015; 49:1-9. [PMID: 25810695 PMCID: PMC4362600 DOI: 10.2478/raon-2013-0071] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2013] [Accepted: 05/05/2013] [Indexed: 01/30/2023] Open
Abstract
Background PET-CT is becoming more and more important in various aspects of oncology. Until recently it was used mainly as part of diagnostic procedures and for evaluation of treatment results. With development of personalized radiotherapy, volumetric and radiobiological characteristics of individual tumour have become integrated in the multistep radiotherapy (RT) planning process. Standard anatomical imaging used to select and delineate RT target volumes can be enriched by the information on tumour biology gained by PET-CT. In this review we explore the current and possible future role of PET-CT in radiotherapy treatment planning. After general explanation, we assess its role in radiotherapy of those solid tumours for which PET-CT is being used most. Conclusions In the nearby future PET-CT will be an integral part of the most radiotherapy treatment planning procedures in an every-day clinical practice. Apart from a clear role in radiation planning of lung cancer, with forthcoming clinical trials, we will get more evidence of the optimal use of PET-CT in radiotherapy planning of other solid tumours.

Local experience in cervical cancer imaging: Comparison in tumour assessment between TRUS and MRI. Rep Pract Oncol Radiother 2015; 20:223-30. [PMID: 25949227 DOI: 10.1016/j.rpor.2015.01.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2014] [Revised: 09/24/2014] [Accepted: 01/21/2015] [Indexed: 01/04/2023] Open
Abstract
OBJECTIVE The aim of study was to analyze the accuracy of TRUS (transrectal ultrasound) vs. MRI (magnetic resonance imaging) and clinical gynecological examination estimation in the evaluation of tumor dimensions. METHODS The patients inclusion criterion included primarily pathologically squamous cell carcinoma, but excluded were patients who had not undergone BT (brachytherapy) and treated with palliative intent. We offer two types of treatment for locally advanced cervical cancer: (a) radiochemotherapy followed by surgery and (b) exclusive radiochemotherapy. Imaging tests follow the presence of tumor and tumor size (width and thickness). Each examination was performed by a different physician who had no knowledge of the others' findings. All patients underwent MRI prior to EBRT (external beam radiation therapy) while 18 of them also at the time of the first brachytherapy application. For the analysis we used the r-Pearson correlation coefficient. RESULTS In 2013, 26 patients with cervical cancer were included. A total of 44 gynecological examinations were performed, 44 MRIs and 18 TRUSs. For the comparisons prior to EBRT the correlation coefficient between TRUS vs. MRI was r = 0.79 for AP and r = 0.83 for LL, for GYN vs. MRI was r = 0.6 for AP and r = 0.75 for LL. Prior to BT for GYN vs. MRI, r values were 0.60 and 0.63 for AP and LL, respectively; for GYN vs. TRUS, r values were 0.56 and 0.78 for AP and LL, respectively. CONCLUSIONS A high correlation between the three examinations was obtained. As such, TRUS can be considered a suitable method in the evaluation of tumor dimensions.

Abstract
OBJECTIVE In order to determine indications for less radical surgery such as modified radical hysterectomy, the risk of pathological parametrial involvement and prognosis of FIGO stage IB1 cervical cancer patients undergoing standard radical hysterectomy with pre-operatively assessed tumor diameter≤2 cm were investigated. METHODS We conducted a retrospective multi-institutional chart review of patients with FIGO stage IB1 cervical cancer who underwent primary surgical treatment between 1998 and 2002. The eligibility criteria for the analyses were (i) histologically-proven squamous cell carcinoma, adenocarcinoma or, adenosquamous cell carcinoma, (ii) radical hysterectomy performed, (iii) clinical tumor diameter data available by MR imaging or specimens by cone biopsy, and (iv) age between 20 and 70. Based on the clinical tumor diameter, patients were stratified into those with the following tumors: i) 2 cm or less (cT≤2 cm) and ii) greater than 2 cm (cT>2 cm). We expected 5-year OS of ≥95% and parametrial involvement<2-3% for patients with cT≤2 cm who underwent radical hysterectomy. RESULTS Of the 1269 patients enrolled, 604 were eligible for the planned analyses. Among these, 571 underwent radical hysterectomy (323 with cT≤2 cm and 248 with cT>2 cm). Parametrial involvement was present in 1.9% (6/323) with cT≤2 cm and 12.9% (32/248) with cT>2 cm. Five-year overall survivals were 95.8% (95% CI 92.9-97.6%) in cT≤2 cm and 91.9% (95% CI 87.6-94.8%) in cT>2 cm patients. CONCLUSION Patients with cT≤2 cm had lower risk of parametrial involvement and more favorable 5-year overall survival. They could therefore be good candidates for receiving less radical surgery.

Abstract
BACKGROUND To safely optimize target volumes using magnetic resonance imaging (MRI) for uterine cervical cancer radiation therapy, MRI findings need to be validated. The aim of this study was to correlate pre-operatively acquired MRI and surgical specimen imaging for uterine cervical cancer patients using deformable image registration and quantify gross tumor volume (GTV) delineation discrepancies. MATERIAL AND METHODS For 16 retrospectively selected early-stage uterine cervical cancer patients, the cervix-uterus structure, uterine cavity and the GTV were delineated on 2D pathology photos after macroscopic intersection and corresponding pre-operatively acquired T2-weighted 2D sagittal MR images. Segmentations of pathology photos and MR images were simultaneously registered using a three-step multi-image registration strategy. The registration outcome was evaluated by the Dice similarity coefficient (DSC) and the surface distance error (SDE). In addition, GTV expansions within the cervix-uterus structure needed to obtain 95% GTV coverage were determined. RESULTS After three-step multi-image registration, the median DSC and median SDE were 0.98 and 0.4 mm (cervix-uterus) and 0.90 and 0.4 mm (uterine cavity), respectively. The average SDE around the GTV was 0.7 mm (range, 0.1 mm - 2.6 mm). An underestimation of MRI-based GTV delineations was found when no margin was applied, indicated by a mean GTV coverage of 61%. To obtain 95% GTV coverage for 90% of the patients, a minimum 12.0 mm margin around MRI-based GTVs was needed. CONCLUSION The presented three-step multi-image registration strategy was suitable and accurate to correlate MRI and pathology data for uterine cervical cancer patients. To cover the pathology-based GTV, a margin of at least 12.0 mm around GTV delineations on T2-weighted MRI is needed.

Abstract
MR imaging and (18)F-FDG PET/CT play central and complementary roles in the care of patients with gynecologic cancer. Because treatment often requires combinations of surgery, radiotherapy, and chemotherapy, imaging is central to triage and to determining prognosis. This article reviews the use of the 2 imaging modalities in the initial evaluation of 3 common cancers: uterine cervical, uterine endometrial, and epithelial ovarian. Imaging features that affect management are highlighted, as well as the relative strengths and weaknesses of the 2 modalities. Use of imaging after initial therapy to assess for recurrence and to plan salvage therapy is described. Newer functional and molecular techniques in MR imaging and PET are evaluated. Finally, we describe our initial experience with PET/MR imaging, an emerging technology that may prove to be a mainstay in personalized gynecologic cancer care.

Abstract
PURPOSE To more accurately define clinical target volume for cervical cancer radiation treatment planning by evaluating tumor microscopic extension toward the uterus body (METU) in International Federation of Gynecology and Obstetrics stage Ib-IIa squamous cell carcinoma of the cervix (SCCC). PATIENTS AND METHODS In this multicenter study, surgical resection specimens from 318 cases of stage Ib-IIa SCCC that underwent radical hysterectomy were included. Patients who had undergone preoperative chemotherapy, radiation, or both were excluded from this study. Microscopic extension of primary tumor toward the uterus body was measured. The association between other pathologic factors and METU was analyzed. RESULTS Microscopic extension toward the uterus body was not common, with only 12.3% of patients (39 of 318) demonstrating METU. The mean (±SD) distance of METU was 0.32 ± 1.079 mm (range, 0-10 mm). Lymphovascular space invasion was associated with METU distance and occurrence rate. A margin of 5 mm added to gross tumor would adequately cover 99.4% and 99% of the METU in the whole group and in patients with lymphovascular space invasion, respectively. CONCLUSION According to our analysis of 318 SCCC specimens for METU, using a 5-mm gross tumor volume to clinical target volume margin in the direction of the uterus should be adequate for International Federation of Gynecology and Obstetrics stage Ib-IIa SCCC. Considering the discrepancy between imaging and pathologic methods in determining gross tumor volume extent, we recommend a safer 10-mm margin in the uterine direction as the standard for clinical practice when using MRI for contouring tumor volume.

Abstract
OBJECTIVE Tumor volume is a significant prognostic factor of cervical cancer. It is still unknown about outcome of biopsy-proven IB1 cervical cancer, which is invisible on preoperative magnetic resonance imaging (MRI). The aim was to evaluate retrospectively the postoperative outcomes of MR-invisible stage IB1 cervical cancers. STUDY DESIGN Between January 2001 and December 2007, we reviewed the medical records of 86 patients with biopsy-proven IB1 cervical cancer that was invisible on MRI. During the same period, we also reviewed the medical records of 260 patients with biopsy-proven IB1 cervical cancer that was visible on MRI. Both of these cancer groups were treated with radical hysterectomy and lymph node dissection. MR-invisible and MR-visible IB1 cancers were compared in terms of pathologic parameters and long-term survival rate. RESULTS The median sizes and depths of stromal invasion of MR-invisible vs MR-visible IB1 cancers were 4.5 ± 7.1 mm and 33.3% ± 20.1% vs 30 ± 14 mm and 66.7% ± 26.6%, respectively (P = .000). The incidences of lymph node metastasis, parametrial invasion, and lymphovascular invasion were 1.1% (1/86 cases) and 18.8% (49/260 cases; P = .000; odds ratio, 19.7), 0% (0/86 cases) and 6.5% (17/260 cases; P = .009; odds ratio, 12.4), and 4.7% (4/86 cases) and 26.9% (70/260 cases; P = .000; odds ratio, 7.6) in the MR-invisible and MR-visible IB1 cancers, respectively. Recurrence-free and overall 5-year survival rates of MR-invisible vs MR-visible IB1 cancers were 98.8% (85/86 cases) vs 91.2% (237/260 cases) and 100% (86/86 cases) vs 95.8% (249/260 cases), respectively (P = .011 and .045). CONCLUSION MR-invisible IB1 cancer provides better postoperative outcomes than MR-visible IB1 cancer because of the much lower tumor burden.

Abstract
Background Optimal applicator insertion is a precondition for the success of cervix cancer brachytherapy (BT). We aimed to assess feasibility and efficacy of MRI-assisted pre-planning, based on applicator insertion in para-cervical anaesthesia (PCA). Patients and methods. Five days prior to BT, the pre-planning procedure was performed in 18 cervix cancer patients: tandem-ring applicator was inserted under PCA, pelvic MRI obtained and applicator removed. Procedure tolerability was assessed. High risk clinical target volume (HR CTV) and organs at risk were delineated on the pre-planning MRI, virtual needles placed at optimal positions, and dose planning performed. At BT, insertion was carried out in subarachnoidal anaesthesia according to pre-planned geometry. Pre-planned and actual treatment parameters were compared. Results Pre-planning procedure was well tolerated. Median difference between the pre-planned and actual needle insertion depth and position were 2 (0–10) mm and 4 (0–30) degrees, respectively. The differences between the pre-planned and actual geometric and dosimetric parameters were statistically non-significant. All actual needles were positioned inside the HR CTV and outside the organs at risk (OAR). Conclusions Our pre-planning approach is well tolerated and effective. Pre-planned geometry and dose distribution can be reproduced at BT.

Abstract
Magnetic resonance imaging (MRI) represents the reference imaging modality for image guided adaptive brachytherapy (IGABT) of cervix cancer. Accurate interpretation of pre-treatment MRI is required for proper understanding of the tumor extent and topography at IGABT. Planning and optimal timing of the application begins already before treatment, and may need to be adapted during external beam irradiation (EBRT) according to additional clinical and/or radiological findings. The level of MRI utilization in IGABT depends on the infrastructural capabilities of individual centers, ranging from no use at all to repetitive imaging during EBRT and each IGABT fraction. In this article, we summarize the role of different imaging modalities and practical aspects of MRI interpretation in cervix cancer IGABT, concentrating on the systematic evaluation of post-insertion images. MRI with the applicator in place from the radiation oncologist’s perspective should begin with immediate identification of eventual complications of the application procedure and assessment of the implant adequacy, followed by appropriate corrective measures in case of adverse findings. Finally, the tumor extent, topography, and treatment response should be evaluated in the context of initial clinical and radiological findings to allow for an appropriate selection and delineation of the target volumes.
