The Prevalence of Uterine Fibroids in African American Women with Hemoglobin SS Sickle Cell Disease as Determined by Pelvic Magnetic Resonance Imaging. Acad Radiol 2021; 28:1748-1753. [PMID: 32819834 DOI: 10.1016/j.acra.2020.07.032] [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: 07/01/2020] [Revised: 07/24/2020] [Accepted: 07/24/2020] [Indexed: 11/18/2022]
Abstract
RATIONALE AND OBJECTIVES This study explores the relationship between the development of uterine fibroids and hemoglobin SS sickle cell disease (SCD) by examining the prevalence of uterine fibroids as detected by pelvic magnetic resonance imaging (MRI) in African American (AA) women with and without SCD. MATERIALS AND METHODS A single-center, retrospective review was performed of all adult AA women at a large, academic medical center who received pelvic MRI from January 1, 2007 to December 31, 2018. Propensity score matching conditional on age and ZIP code evaluated the differences in fibroid prevalence between the two groups. Subanalyses by age in 10-year intervals were also performed. RESULTS Twenty-one (23.9%) of 88 patients with SCD had fibroids on pelvic MRI versus 1493 (52.1%) of 2868 patients without SCD (p value <0.001). After propensity score matching, 21 (24.7%) of 85 patients with SCD compared to 52 (61.2%) of 85 patients without SCD had fibroids (p value <0.001). Subanalyses in 10-year age intervals showed significance for patients between 30 and 39 years old in which 4 (13.8%) of 29 SCD patients versus 374 (65.3%) of 573 no SCD patients had fibroids (p value <0.001), and for patients between 40 and 49 years old in which 9 (42.9%) of 21 SCD patients versus 667 (73.8%) of 904 no SCD patients had fibroids (p value = 0.002). CONCLUSION These findings indicate an overall significantly lower prevalence of uterine fibroids in AA women with SCD, suggesting that SCD may be protective against the development of uterine fibroids in these patients.

The utility of initial staging PET-CT as a baseline scan for surveillance imaging in stage II and III melanoma. Surg Oncol 2020; 35:533-539. [PMID: 33161362 DOI: 10.1016/j.suronc.2020.10.018] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 09/11/2020] [Accepted: 10/27/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND This study evaluates the utility of whole-body PET-CT for the initial staging and subsequent surveillance imaging of patients with completely resected stage II and stage III melanoma. METHODS A single-center, retrospective review of patients who received perioperative whole-body PET-CT from January 1, 2005 to December 1, 2019 within three months of initial melanoma diagnosis was performed. RESULTS Of 258 total patients with completely resected melanoma who had a PET-CT within 3 months after their melanoma diagnosis, 113 had stage II and 145 had stage III melanoma. PET-CT detected distant metastasis in 3 (2.7%) of 113 stage II patients and 7 (4.8%) of 145 stage III patients. 179 of 258 patients had adequate follow-up time to determine whether they received surveillance cross-sectional imaging and whether they had a melanoma recurrence. 143 (79.9%) received subsequent surveillance imaging, 74 of whom developed a recurrence. In 64 (86.5%) of 74 cases, recurrence was detected by routine surveillance. 26 (34.2%) of 76 stage II and 65 (63.1%) of 103 stage III patients developed a recurrence. The median time to recurrence among the 179 patients for stage II and III was 16.3 and 13.0 months, respectively. CONCLUSIONS These findings indicate that baseline staging with whole-body PET-CT rarely provides information that changes initial management. Rather, the value of the initial PET-CT is as a baseline for subsequent surveillance scans. Therefore, it may be premature to discourage cross-sectional imaging for patients with stage II and III melanoma without supportive evidence or a reliable biomarker of recurrent disease.

Abstract
BACKGROUND Cutaneous malignant melanoma is a neoplasm whose incidence and mortality are dramatically increasing. 18F-FDG PET/CT gained clinical acceptance over the past 2 decades in the evaluation of several glucose-avid neoplasms, including malignant melanoma, particularly for the assessment for distant metastases, recurrence and response to therapy. OBJECTIVE To describe the advancements of nuclear medicine for imaging melanoma with particular attention to 18F-FDG-PET and its current state-of-the-art technical innovations. METHODS A comprehensive search strategy was used based on SCOPUS and PubMed databases. From all studies published in English, we selected the articles that evaluated the technological insights of 18FFDG- PET in the assessment of melanoma. RESULTS State-of-the-art silicon photomultipliers based detectors ("digital") PET/CT scanners are nowadays more common, showing technical innovations that may have beneficial implications for patients with melanoma. Steady improvements in detectors design and architecture, as well as the implementation of both software and hardware technology (i.e., TOF, point spread function, etc.), resulted in significant improvements in PET image quality while reducing radiotracer dose and scanning time. CONCLUSION Recently introduced digital PET detector technology in PET/CT and PET/MRI yields higher intrinsic system sensitivity compared with the latest generation analog technology, enabling the detection of very small lesions with potential impact on disease outcome.

Abstract
PURPOSE To study the utility of positron emission tomography with computerized tomography (PET/CT) in patients with a stage I-III melanoma. PATIENTS AND METHODS PET/CT findings from all patients with a stage I-III melanoma attended at our hospital from September 2011 to November 2015 were reviewed. RESULTS Data from 83 patients with a stage I-III melanoma, 39 patients with a positive sentinel lymph node biopsy (SLNB) and 35 patients with locoregional recurrences were analyzed. Sensitivity of PET/CT in clinical stage I-III patients was 5%, with a 14% of false positives. In patients with a positive SLNB, PET/CT previous to complete lymph node dissection had a 23% of false negatives. In patients with clinical locoregional recurrences, PET/CT findings revealed asymptomatic visceral distant metastasis in 25.7%. CONCLUSIONS PET/CT has a significant rate of false positive and negative results in patients with a stage I-III melanoma. Utility in patients with nodal locoregional recurrences seems higher than in patients with skin metastases.

Abstract
Purpose The Region of Southern Denmark (RSD), covering 1.2 of Denmark’s 5.6 million inhabitants, established a task force to (1) retrieve literature evidence for the clinical use of positron emission tomography (PET)/CT and provide consequent recommendations and further to (2) compare the actual use of PET/CT in the RSD with these recommendations. This article summarizes the results. Methods A Work Group appointed a professional Subgroup which made Clinician Groups conduct literature reviews on six selected cancers responsible for 5,768 (62.6 %) of 9,213 PET/CT scans in the RSD in 2012. Rapid Evidence Assessment was applied, using the methodology of systematic reviews with predefined limitations to search PubMed, Embase and the Cochrane Library for articles published in English/Danish/Swedish/Norwegian since 2002. PICO questions were defined, data recorded and quality appraised and rated with regard to strength and evidence level. Consequent recommendations for applications of PET/CT were established. The actual use of PET/CT was compared with these, where grades A and B indicated “established” and “useful” and grades C and D “potentially useful” and “non-recommendable” indications, respectively. Results Of 11,729 citations, 1,729 were considered for review, and 204 were included. The evidence suggested usefulness of PET/CT in lung, lymphoma, melanoma, head and neck, and colorectal cancers, whereas evidence was sparse in gynaecological cancers. The agreement between actual use of PET/CT and literature-based recommendations was high in the first five mentioned cancers in that 96.2 % of scans were made for grade A or B indications versus only 22.2 % in gynaecological cancers. Conclusion Evidence-based usefulness was reported in five of six selected cancers; evidence was sparse in the sixth, gynaecological cancers. Actual use of PET/CT agreed well with recommendations.

Abstract
![]()
Positron
emission tomography (PET) is an important modality in
the field of molecular imaging, which is gradually impacting patient
care by providing safe, fast, and reliable techniques that help to
alter the course of patient care by revealing invasive, de facto procedures
to be unnecessary or rendering them obsolete. Also, PET provides a
key connection between the molecular mechanisms involved in the pathophysiology
of disease and the according targeted therapies. Recently, PET imaging
is also gaining ground in the field of drug delivery. Current drug
delivery research is focused on developing novel drug delivery systems
with emphasis on precise targeting, accurate dose delivery, and minimal
toxicity in order to achieve maximum therapeutic efficacy. At the
intersection between PET imaging and controlled drug delivery, interest
has grown in combining both these paradigms into clinically effective
formulations. PET image-guided drug delivery has great potential to
revolutionize patient care by in vivo assessment
of drug biodistribution and accumulation at the target site and real-time
monitoring of the therapeutic outcome. The expected end point of this
approach is to provide fundamental support for the optimization of
innovative diagnostic and therapeutic strategies that could contribute
to emerging concepts in the field of “personalized medicine”.
This review focuses on the recent developments in PET image-guided
drug delivery and discusses intriguing opportunities for future development.
The preclinical data reported to date are quite promising, and it
is evident that such strategies in cancer management hold promise
for clinically translatable advances that can positively impact the
overall diagnostic and therapeutic processes and result in enhanced
quality of life for cancer patients.
