Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023. Materials and Methods: The survey was conducted from March to December 2024 using a standardized case report form. Data were collected on 86 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. The results of the 2023 survey were compared with those of previous surveys. Results: Data from 12,751 cases were collected from 66 institutions. The mean patient age was 64.6 years, and the proportion of patients aged ≥71 years increased from 9.1% in 1995 to 31.7% in 2023. The proportion of upper-third tumors slightly decreased to 16.8% compared to 20.9% in 2019. Early gastric cancer accounted for 63.1% of cases in 2023.Regarding operative procedures, a totally laparoscopic approach was most frequently applied (63.2%) in 2023, while robotic gastrectomy steadily increased to 9.5% from 2.1% in 2014.The most common anastomotic method was the Billroth II procedure (48.8%) after distal gastrectomy and double-tract reconstruction (51.9%) after proximal gastrectomy in 2023.However, the proportion of esophago-gastrostomy with anti-reflux procedures increased to 30.9%. The rates of post-operative mortality and overall complications were 1.0% and 15.3%, respectively. Conclusions The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.

Purpose: Stem cell transplantation (SCT) has historically played a major role in the long-term remission of mantle cell lymphoma (MCL), an incurable hematological malignancy. Using data from the Korean Society of Bone and Marrow Transplantation registry, we retrospectively analyzed the role of autologous (auto) and allogeneic (allo) SCT in longterm MCL survival. Methods: This study analyzed data from 188 patients (age ≥ 19 years at the time of transplantation) who underwent a transplant for MCL from 2011 to 2020. Progression-free survival (PFS) was defined as the time from transplantation to disease progression, relapse, or death from any cause. Overall survival (OS) was defined as the time from transplan‑ tation to death from any cause or the last follow-up. Results: In total, 109 patients underwent consolidative SCT after first-line chemotherapy. The 3-year PFS and OS rates were 65.4% and 78.5%, respectively, in the auto-SCT group, and 66.7% and 71.4%, respectively, in the allo-SCT group. The PFS and OS did not differ significantly between the auto- and allo-SCT groups. As part of salvage treatment, 52 patients with relapsed or refractory disease underwent auto- or allo-SCT. Patients who underwent auto-SCT with complete remis‑ sion/partial remission status reported better outcomes. In patients with refractory status, allogeneic transplantation using human leukocyte antigen (HLA) fully matched donors was a significantly favorable factor for PFS and OS. Conclusion The long-term survival of patients who underwent consolidative transplantation was similar to that reported in previous studies. Auto-SCT may be beneficial in patients who respond to salvage therapy, whereas allo-SCT with HLA-matched donors may be an alternative for patients with refractory disease. 

In large posterosuperior rotator cuff tears, retear is more likely due to factors such as poor tendon quality, tendon loss, incomplete footprint coverage, and incomplete repair. To reduce the retear rate and promote healing, various strategies have been explored, including augmentation using a human acellular dermal matrix (HADM) allograft patch. However, the traditional patch augmentation with a suture-bridge configuration is complicated and time consuming. Another method to alleviate impingement between the repaired tendon and acromion, similar to the ballooning effect in the subacromial space, is the acromiograft technique. However, a thin acromion may lead to fractures, and such a graft is less likely to incorporate with the repaired tendon. To address these concerns, we developed a new technique that enhances healing through direct contact with the repaired tendon, alleviates impingement with a spacer effect, and simplifies the procedure while ensuring adequate medial coverage including the musculotendinous junction. This article describes our “patch cushioning technique” using an HADM allograft. The present report provides a purely technical description of the procedure.

Myofascial pain syndrome, which has trigger points, is one of the most common causes of acute and chronic musculoskeletal pain. The trigger points formed by damage to the muscle fibers are focal areas of taut bands in the skeletal muscle that are hypersensitive to palpation. When manual pressure is applied over a trigger point, it produces distinct local and referred pain. Although various modalities have been used to treat trigger points, trigger point injection is the most effective treatment modality to inactivate trigger points. This article reviews the diagnosis and treatment of myofascial pain syndrome and the technique of trigger point injection.
