SR | Adding ultrasound to mammography increases breast cancer detection, but increases false-positives and biopsies
3 Apr, 2023 | 13:55h | UTCSummary: The systematic review examined the effectiveness and safety of combining mammography with breast ultrasonography versus mammography alone for breast cancer screening in women at average risk. The research included one randomized controlled trial, two prospective cohort studies, and five retrospective cohort studies, involving a total of 209,207 women.
High certainty evidence from one trial indicated that combining mammography with ultrasonography led to the detection of more breast cancer cases than mammography alone (5 vs. 3 per 1000 women). However, this combination also led to a higher number of false-positive results and biopsies. For every 1000 women screened with the combined approach, 37 more received a false-positive result, and 27 more women underwent a biopsy.
Secondary analysis of the trial data revealed that in women with dense breasts, the combined screening detected more cancer cases than mammography alone, while cohort studies for women with non-dense breasts showed no statistically significant difference between the two screening methods.
The included studies did not analyze whether the higher number of detected cancers with the combined screening method resulted in lower mortality rates compared to mammography alone. Further research, including randomized controlled trials or prospective cohort studies with longer observation periods, is needed to assess the impact of the two screening interventions on morbidity and mortality.

Scanxiety among adults with cancer: a scoping review to guide research and interventions
14 Mar, 2023 | 13:55h | UTCSummary: The article presents a scoping review of existing literature on scanxiety, which refers to the anxiety and distress experienced by cancer patients before and after medical imaging scans. The authors identified and synthesized findings from 36 articles on scanxiety among adults diagnosed with current or prior cancer.
The authors observed that scanxiety is a prevalent issue throughout the cancer continuum and may be linked to various factors related to the procedure itself or the uncertainty surrounding the possible outcomes of the scans.
The waiting period between the scan procedure and receipt of the results was described as particularly stressful, with participants reporting feeling overwhelmed by negative thoughts and fears about the potential outcomes of the scan. Some participants even found it difficult to focus on daily activities or responsibilities during this time.
The authors suggest that implementing supportive measures during scan experiences, including examining the waiting period between scans and scan results, could enhance the well-being for individuals with cancer who are going through different stages of treatment.

Cohort Study | Long-term changes in the size of pituitary microadenomas
3 Mar, 2023 | 13:49h | UTCSummary: The prevalence of pituitary lesions in radiologic studies is estimated to be 10% to 38.5%. However, it is unclear how frequently incidental lesions should be monitored by serial pituitary MRI. A retrospective longitudinal cohort study was conducted to evaluate changes in pituitary microadenomas over time. During the study period (from 2003 to 2021), 414 patients with pituitary microadenomas were identified, and 177 patients had more than 1 MRI. Approximately two-thirds of the microadenomas demonstrated no change or a decrease in size, while the rest exhibited a slow growth rate, indicating that less frequent monitoring could be considered safe.

Study suggests there is little added value from follow-up pelvic CT after treatment of hepatocellular carcinoma
23 Feb, 2023 | 13:39h | UTCSummary: The study investigated the added value of pelvic coverage at follow-up liver CT in detecting pelvic metastasis or incidental tumors in patients treated for hepatocellular carcinoma (HCC). The study found that the incidence of isolated pelvic metastasis or incidental pelvic tumor was low in patients treated for HCC. The cumulative rates of isolated pelvic metastasis and incidental pelvic tumor were 1.4% and 0.5%, respectively, at 3 years. Only baseline T stage was associated with an increased risk of isolated pelvic metastasis. The study concludes that excluding the pelvic scan can reduce radiation dose and decrease the workload for radiologists. However, the study also had limitations, such as being retrospective and single-center. Therefore, more research is necessary to study the optimal scanning strategy for the pelvis and the effect of pelvic CT coverage on survival in patients with HCC.

Cohort Study | One third of patients hospitalized with Covid-19 persist with lung abnormalities after 2 years
21 Feb, 2023 | 11:47h | UTCSummary: The study aimed to assess changes in chest CT abnormalities and pulmonary function in patients two years after recovery from SARS-CoV-2 infection. The prospective study followed 144 participants discharged from the hospital after SARS-CoV-2 infection between January 15 and March 10, 2020. The participants underwent serial chest CT scans and pulmonary function tests at 6 months, 12 months, and 2 years after symptom onset. The study found that 39% of participants had persistent interstitial lung abnormalities at 2 years, and this was associated with respiratory symptoms and decreased diffusion pulmonary function.

Gadolinium nanoparticles detected in kidney tissue of patients after MRI with gadolinium contrast, raising safety concerns
20 Feb, 2023 | 12:24h | UTCSummary: Researchers have discovered that tiny particles of the rare earth metal gadolinium can infiltrate kidney cells, potentially causing side effects. These particles, used to enhance MRI scans, were found in human and rodent specimens in a study that used electron microscopy to detect them. Gadolinium is typically tightly bound to chelating molecules in MRI contrast agents so that it can be eliminated via the kidneys, but the researchers found that some particles can leach out and build up in tissues. This raises questions about the safety of contrast agents containing gadolinium, which are used in around 50% of MRI scans, and highlights the need for further research into the risks and potential harms associated with these agents.

RCT | Preoperative MRI in breast cancer did not influence local relapse-free survival, overall survival, or reoperation rates
15 Feb, 2023 | 15:57h | UTCSummary: This study investigated the impact of preoperative magnetic resonance imaging (MRI) on survival and surgical outcomes in conservative surgery for breast cancer. The randomized controlled trial included female participants with stage 0-III breast cancer, eligible for breast-conserving surgery. The study found that preoperative MRI increased the rate of mastectomies by 8% compared to routine radiologic exams using mammography and ultrasound. However, preoperative MRI did not impact the rates of local relapse-free survival, overall survival, or reoperation.*
