Introduction: In the late 20th century, limb salvage surgery emerged as a game-changer for treating musculoskeletal tumors, evolving with advanced techniques to offer both survival and functional preservation. The objective of the study is to discuss key metrics, such as overall survival, metastasis-free survival, local recurrence-free survival, and functional outcomes, recognizing the importance of these measures. Despite hurdles such as potential infections and implant issues, it is crucial to understand and address complications, which is also highlighted in this study.
Methods: This was a retrospective review of patients with primary malignant bone tumors from January 2017 to December 2023 and the progress was followed up till June 2024. Variables assessed included patient age, size and anatomical location of the primary tumor, metastasis, histological subtype, stage and grade of tumor, resection margins, treatment provided, functional outcome, and complications. The data were analyzed with SPSS version 27. Five-year metastasis-free survival, recurrence-free survival, and overall survival were analyzed by using the Kaplan-Meier method.
Results: A total of 115 patients were analyzed, among which the most common type of tumor was osteosarcoma, found in 79 (68.7%) patients. Out of the 115 patients, 20 (17.4%) expired, six were lost to follow-up, and the five-year overall survival rate was approximately 78% (95% CI: 69.6-87.5%). Fourteen (12.2%) patients had local recurrence, and the five-year recurrence-free survival rate was approximately 83.2% (95% CI: 74.4-92.6%). Meanwhile, 27 (23.5%) patients had distant metastasis, and the five-year metastasis-free survival rate was approximately 67.5% (95% CI: 55.3-82.3%). Complications occurred in 31 (27%) patients, with 13 (11.3%) patients having local soft-tissue-related complications.
Conclusion: We observed good survival and functional outcomes in patients treated with wide-margin excision of bone sarcomas and reconstruction with mega prostheses.

Background: The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S.

Background: Predicting burn-related mortality is vital for family counseling, triage, and resource allocation. Several of the burn-specific mortality prediction scores have been developed, including the Abbreviated Burn Severity Index (ABSI) in 1982. However, these scores are not tested for accuracy to support contemporary estimates of the global burden of burn injury.

Nasopharyngeal carcinoma (NPC) is a prevalent malignancy in China, commonly associated with undifferentiated cell types and Epstein-Barr virus (EBV) infection. The presence of intense lymphocytic infiltration and elevated expression of programmed cell death ligand 1(PD-L1) in NPC highlights its potential for immunotherapy, yet current treatment outcomes remain suboptimal. In this review, we explore the tumor microenvironment of NPC to better understand the mechanisms of resistance to immunotherapy, evaluate current therapeutic strategies, and pinpoint emerging targets, such as tertiary lymphoid structures (TLSs), that could enhance treatment outcomes and prognostic accuracy.
