Purpose: To analyze the results of the subscapular sling procedure developed for anterior shoulder instability in patients with less than 10% anterior glenoid bone loss.
Methods: Patients were treated surgically with the arthroscopic subscapular sling procedure. A semitendinosus graft was used to reconstruct the anterior labrum and to establish a sling suspension around the upper part of the subscapularis tendon.
Objectives: The randomized controlled trial comparing digital breast tomosynthesis and synthetic 2D mammograms (DBT + SM) versus digital mammography (DM) (the To-Be 1 trial), 2016-2017, did not result in higher cancer detection for DBT + SM. We aimed to determine if negative cases prior to interval and consecutive screen-detected cancers from DBT + SM were due to interpretive error.
Methods: Five external breast radiologists performed the individual blinded review of 239 screening examinations (90 true negative, 39 false positive, 19 prior to interval cancer, and 91 prior to consecutive screen-detected cancer) and the informed consensus review of examinations prior to interval and screen-detected cancers (n = 110).
Background: Many breast cancer survivors experience anxiety related to dying from their disease even if it is detected at an early stage. We aimed to increase knowledge about fatal and non-fatal breast cancer by describing how histopathological tumour profiles and detection modes were associated with 10-year breast cancer-specific survival.
Methods: This cohort study included data from women targeted by BreastScreen Norway (aged 50-69) and diagnosed with invasive breast cancer during 1996-2011.
Rationale And Objectives: To explore radiological aspects of interval breast cancer in a population-based screening program.
Materials And Methods: We performed a consensus-based informed review of mammograms from diagnosis and prior screening from women diagnosed with interval cancer 2004-2016 in BreastScreen Norway. Cases were classified as true (no findings on prior screening mammograms), occult (no findings at screening or diagnosis), minimal signs (minor/non-specific findings) and missed (obvious findings).
Objective: To perform a radiological review of mammograms from prior screening and diagnosis of screen-detected breast cancer in BreastScreen Norway, a population-based screening program.
Methods: We performed a consensus-based informed review of mammograms from prior screening and diagnosis for screen-detected breast cancers. Mammographic density and findings on screening and diagnostic mammograms were classified according to the Breast Imaging-Reporting and Data System®.
Purpose: Treatment of anterior glenoid bone loss in patients with recurrent anterior shoulder instability is a challenge. The subscapular sling method with quadriceps tendon bone (QTB) graft is a modification of the subscapular sling with a semitendinosus (ST) graft. The aim of the study was to test the biomechanical stability of the QTB sling procedure in human shoulder cadavers with severe anterior glenoid bone loss.

- Curative radiation therapy is essential for prostate cancer treatment, and the study analyzed long-term risks of second cancers (SC) and overall survival (OS) among patients receiving hormone therapy (ET) alone versus combined with radiation (RT).
- Among the 860 analyzed patients, those receiving combined treatment had a higher incidence of SC, especially urinary bladder cancer (UBC), but improved overall survival rates compared to those on hormone therapy alone.
- The findings indicate that despite a heightened risk for certain second cancers, the overall survival benefits associated with combined ET and RT therapies significantly outweigh the potential risks.
Article Synopsis
- Several European screening mammography programs recommend that radiologists read at least 5000 mammograms annually based on expert opinion, but the actual impact of reading volume on performance is unclear.
- A study analyzing data from BreastScreen Norway over a decade found variability in reading volumes among radiologists, with a median ranging from 153 to 19,500 mammograms per year.
- Results indicated that while sensitivity and screening-detected breast cancer rates remained stable across various reading volumes, higher annual volumes led to a notable decrease in both sensitivity and false-positive rates, suggesting a complex relationship between reading volume and diagnostic performance.
The aim of this registry-based cohort study was to estimate second cancer (SC) risk following radical prostate cancer (PC) treatment and evaluate if the risk was influenced by radiotherapy. We collected data from the Cancer Registry of Norway on all patients with PC as first cancer diagnosis, from 1997 to 2014. Standardized incidence ratios (SIRs) for SC were calculated by comparing our cohort to the standard male population.

The cohort consisted of 46,428 women (ages 49-71 years) who participated in BreastScreen Norway between 2007 and 2014 and had information on VMD and breast cancer risk factors. We estimated means of percent and absolute VMD associated with age, menopausal status, body mass index (BMI), and other factors.

The aim of the present study was to evaluate whether the risk of breast cancer (BC) in men with PC as their first cancer diagnosis was influenced by PRT.
Methods And Materials: From the Norwegian Cancer Registry, we collected data from all patients with PC as their first cancer diagnosis from 1997 to 2014.
Background: High mammographic density might mask breast tumors, resulting in delayed diagnosis or missed cancers.
Purpose: To investigate the association between mammographic density and histopathologic tumor characteristics (histologic type, size, grade, and lymph node status) among women screened in the Norwegian Breast Cancer Screening Program.
Material And Methods: Information about 1760 screen-detected ductal carcinoma in situ (DCIS) and 7366 invasive breast cancers diagnosed among women aged 50-69 years, 1996-2010, was analyzed.
Purpose: To compare performance measures before, during, and after the transition from screen-film mammography (SFM) to full-field digital mammography (FFDM) in a population-based screening program.
Materials And Methods: No institutional review board approval was required for this analysis involving anonymized data for women aged 50-69 years enrolled in the Norwegian Breast Cancer Screening Program during 1996-2010. The χ(2) test was used to examine the equality of proportions of recall rates, positive predictive value of recall examinations and of invasive procedures, in addition to rates of screening-detected and interval cancers in women initially screened with SFM and FFDM and for women subsequently screened with SFM after SFM, FFDM after SFM, and FFDM after FFDM.
Rationale And Objectives: To increase radiologic knowledge, the distribution of mammographic features on prior screening mammograms of missed interval and screen-detected cancers was compared to the distribution on diagnostic mammograms of screen-detected cancers. The same variables were compared on mammograms of discordant and concordant screen-detected cancers.
Materials And Methods: The study was performed in Møre og Romsdal County, Norway, as a part of the quality assurance of the Norwegian Breast Cancer Screening Program.
Background: Studies comparing analog and digital mammography in breast cancer screening have shown conflicting results. Little is known about the use of digital photon-counting detectors.
Purpose: To retrospectively compare performance indicators in screen-film (SFM) and full-field digital mammography (FFDM) using a photon-counting detector in a population-based screening program.
