Background: Early breast cancer outcomes have improved substantially, yet surgery may carry physical and psychosocial costs. Cryotherapy has gained attention as a minimally invasive alternative to surgery for select patients with breast cancer: particularly, those with small, unifocal, hormone receptor-positive tumors. Given rapidly expanding but heterogeneous reports, this state-of-the-art review therefore aims to synthesize information on how breast cryotherapy is performed, for whom it is most suitable, what outcomes to expect, and where evidence is still immature. Methods: We queried MEDLINE (via PubMed), Embase (via Ovid), and the Cochrane Library up to January 2025, using terms related to “breast neoplasms,” “cryotherapy,” and “cryoablation.” Eligible studies included clinical trials, cohort studies, and case series reporting outcomes of cryotherapy in breast cancer. Data were extracted on patient characteristics, procedural parameters, recurrence, survival, and complications. The risk of bias was assessed using the MINORS tool, and certainty of evidence was appraised with the GRADE framework. Results: A total of thirty one studies (comprising 1357 patients) formed the evidence corpus summarized here. Most involved early-stage, hormone receptor-positive breast cancers ≤ 2 cm treated with percutaneous cryoablation. Local recurrence, defined as any ipsilateral breast tumor recurrence confirmed radiologically or histologically, ranged from 0 to 68.8%, with smaller, unifocal tumors achieving the best control. Overall survival exceeded 80% in early-stage disease, while complications were generally minor, including bruising, hematoma, and skin erythema. Patient satisfaction was high, with favorable cosmetic outcomes reported in limited studies. However, the follow-up duration ranged from 1 month to 10 years (with nearly half < 1 year), and protocols varied substantially across studies. In summary, breast cryotherapy appears safe and can achieve encouraging local control and cosmetic results in carefully selected early-stage cases. Its role in aggressive subtypes, larger or multifocal disease, and as part of multimodal regimens requires further study. Conclusions: Standardized protocols, imaging/reporting conventions, and longer follow-up with patient-reported outcomes are needed to advance the field and further define where cryotherapy can appropriately de-escalate surgery.

Background: Idiopathic granulomatous mastitis (IGM) is a rare, benign, chronic inflammatory breast condition that poses diagnostic and therapeutic challenges. While corticosteroids are standard first-line therapy, some patients require additional immunomodulation, such as methotrexate. Predictive factors for step-up therapy remain poorly characterized. This study aimed to identify clinical, imaging, and pathological factors predictive of step-up therapy in IGM and evaluate associations between treatment approach and outcomes. Methods: A retrospective cohort study of women diagnosed with IGM was conducted between May 2022 and June 2024 at a tertiary center in Singapore. Data on demographics, clinical presentation, imaging, histopathology, and treatment were extracted. Step-up therapy was defined as methotrexate use following corticosteroids. Primary outcome was predictors of step-up therapy; secondary outcomes included treatment success, relapse, surgery, and time to remission. Statistical analyses included chi-square/Fisher’s exact tests, Cox models, and Kaplan-Meier analysis. Results: Fifty-two women (median age 39 years) were included; 26 (50%) required step-up therapy. Predictors included oral contraceptive (OCP) use (RR 1.92; 95% CI 1.45–2.53; p < 0.001), smoking (RR 2.00; 95% CI 1.49–2.69; p < 0.001), flares (RR 2.33; 95% CI 1.44–3.79; p = 0.002), and percutaneous aspiration (RR 2.10; 95% CI 1.53–2.88; p = 0.025). Patients receiving methotrexate had lower relapse rates (RR 1.23; 95% CI 1.12–1.36; p < 0.001) but longer time to remission (adjusted HR 0.09; 95% CI 0.02–0.46; p = 0.004). Conclusions: OCP use, smoking, flares, and aspiration need may predict step-up therapy in IGM. Early identification could guide a more personalized, potentially top-down treatment.

Case: This is an unusual case of annular ligament interposition into the radiocapitellar joint (ALIRJ) in an 18-year-old female volleyball player with hyperlaxity, who experienced acute elbow pain and restricted motion following stretching. Magnetic resonance imaging confirmed annular ligament interposition, and reduction was successfully achieved using repetitive pronation and supination with traction and flexion in hyperpronation. After 14 months, the patient was pain free, with full range of motion. Conclusion: ALIRJ is a common pediatric condition but is rare in adults. This case highlights the need to consider ALIRJ in adult patients with hyperlaxity and demonstrates the effectiveness of tailored maneuvers to avoid misdiagnosis.

Objective: Spinal stenosis and degenerative spinal disorders are increasingly prevalent and have a substantial impact on quality of life. Surgical decompression, performed using either open microscopic or endoscopic approaches, remains a cornerstone of management for these conditions. This study examines evolving trends in single-level lumbar spinal decompression procedures performed at a tertiary academic hospital in Singapore.Methods: A retrospective observational study was conducted involving 588 patients who underwent single-level spinal decompression between 2021 and 2024, including endoscopic spine surgery (ESS; n=364) and microdecompression (n=224). Primary outcome measures were changes in 36-Item Short Form Health Survey (SF-36) and visual analogue scale (VAS) scores at 3 months, 6 months, and 2 years postoperatively. Secondary outcomes included length of hospital stay, reoperation rates, and operative time. Patient demographics, spinal level and pathology characteristics, surgical techniques, and postoperative outcomes were analyzed. Difference-in-differences (DID) analysis was used to compare outcomes between the 2 groups.Results: Both groups demonstrated significant postoperative improvements in SF-36 and VAS scores. At 2 years, Short Form Health Survey physical function (SFPF) scores improved in the endoscopic group (mean difference [MD], 18.6; standard deviation [SD], 21.7; p=0.064) and in the open microscopic group (MD, 36.7; SD, 20.9; p=0.007), with a non-significant DID of -18.1 (p=0.155). No DID comparisons across SF-36 domains reached statistical significance. Mean operative time for endoscopic procedures decreased from 249 minutes in 2022 to 145 minutes in 2024, reflecting a procedural learning curve. Surgeons with higher endoscopic caseloads exhibited greater improvements in functional outcomes.Conclusion: Both endoscopic and open microscopic decompression achieve comparable short- and long-term clinical outcomes. ESS provides similar effectiveness while being associated with shorter recovery periods and reduced hospital stay. Further research is warranted to identify factors contributing to incomplete symptom resolution or the need for revision surgery.
