Background: A nationwide Rehabilitation at Home Care Pilot Program for patients undergoing lower extremity orthopedic surgeries has been ongoing since 2020. The program was designed to improve clinical outcomes through early mobilization and rehabilitation after discharge. This study aimed to analyze the interim data to assess its effectiveness and suggest improvements, particularly for older patients who are more vulnerable compared to younger patients. Methods: We analyzed the data of 872 patients from seven hospitals. Patients were divided into an older-age group (OG; ≥60 years) and younger-age group (YG; <60 years). The Berg Balance Scale (BBS) and Numeric Rating Scale (NRS) scores for pain were the main outcomes. Results: Participants were categorized into OG (n=801) and YG (n=71). The most common surgeries were knee joint replacement (63.7%) in OG and hip joint replacement in YG (77.5%). It took more days to enroll in the pilot program in OG (4.4 days) than YG (3.2 days). OG showed less improvement in BBS than YG for all surgeries (23.3 vs. 31.9) and hip joint surgery (19.8 vs. 33.5). In patients with hip joint replacement in OG, those with a higher number of comorbidities (≥3) showed less BBS improvement than those with fewer comorbidities (<3). In the pain domain, NRS scores decreased in both groups. Conclusion The postoperative rehabilitation education program appeared to be effective in improving physical function and reducing pain severity, though the improvement was less obvious in older patients who may require a more comprehensive approach compared to younger patients.

Purpose: To investigate the epidemiological trends and socioeconomic disparities associated with ankylosing spondylitis (AS) in South Korea over a decade (2010–2021) using National Health Insurance Service (NHIS) claims data. Materials and Methods: Employing data from the NHIS database, this study identified 31753 incident AS patients in 2010–2021.We calculated the annual age-standardized prevalence and incidence rates and analyzed crude incidence rates and diagnostic patterns across age groups. Additionally, we compared the mean annual proportions of medical aid recipients between AS patients and the general population, utilizing p for trend analysis to assess the differences between the two groups across increasing age groups. Results: The study period saw a steady increase in age-standardized prevalence (from 34.6 to 91.0 per 100000) and incidence rates (from 4.41 to 8.33 per 100000 person-years), with the most substantial rise of incidence found in younger demographics. Diagnostic trends revealed a shift from internal medicine (IM) to other specialties including orthopedics with increasing patient age groups (p for trend=0.008), indicating old-age diagnosis in non-IM departments. A 1.4-fold higher proportion of medical aid recipients in AS patients (p<0.001) and the widening gap of dependency on medical aid in older age groups (p for trend=0.012) compared to the general population highlight socioeconomic disparities. Conclusion This comprehensive analysis reveals the growing epidemiological burden of AS, especially in younger populations, and the socioeconomic disparities regarding the disease in South Korea. It underscores the need for early diagnosis and effective treatment strategies, paving the way for health interventions and policies aimed at improving patient outcomes and addressing socioeconomic disparities.

Purpose: The aim of this retrospective study was to evaluate the efficacy of adjuvant cisplatin-based chemotherapy in patients with locally advanced upper tract urothelial carcinoma (UTUC), administered following radical nephroureterectomy. Materials and Methods: Patients with UTUC, arising from renal pelvis or ureter, staged pT3/T4 or N+ were treated with adjuvant chemotherapy following surgery. The chemotherapy consisted of gemcitabine 1,000 mg/m2 on days 1 and 8, cisplatin 70 mg/m2 on day 1. Treatment was repeated every 3 weeks for up to 4 cycles. Endpoints included disease-free survival (DFS), metastasis-free survival (MFS), and safety. Results: Among 89 eligible patients, 85 (95.5%) completed at least 3 cycles of adjuvant chemotherapy. Chemotherapy was well tolerated, the main toxicities being mild-to-moderate gastrointestinal toxic effects and pruritus. With a median follow-up of 37 months, median DFS was 30 months (95% confidence interval, 22 to 39), and the median MFS was not reached. The 3-year DFS and MFS were 44% and 56%, respectively. Multivariate analyses revealed that the main factor associated with DFS and MFS was the lymph node involvement, whereas age, T category, grade, or the primary site of UTUC were not significantly associated with DFS or MFS. Conclusion Adjuvant cisplatin-based chemotherapy after radical surgery of pT3/T4 or N+ UTUC was feasible and may demonstrate benefits in DFS and MFS. Whether novel agents added to the chemotherapy regimen, as a concurrent combination or maintenance, impacts on survival or reduces the development of metastases remains to be studied.

In recent years, next-generation sequencing (NGS)–based genetic testing has become crucial in cancer care. While its primary objective is to identify actionable genetic alterations to guide treatment decisions, its scope has broadened to encompass aiding in pathological diagnosis and exploring resistance mechanisms. With the ongoing expansion in NGS application and reliance, a compelling necessity arises for expert consensus on its application in solid cancers. To address this demand, the forthcoming recommendations not only provide pragmatic guidance for the clinical use of NGS but also systematically classify actionable genes based on specific cancer types. Additionally, these recommendations will incorporate expert perspectives on crucial biomarkers, ensuring informed decisions regarding circulating tumor DNA panel testing.
