The treatment of sarcomas has been challenging due to their heterogeneity, rarity in the general population, relative insensitivity to chemotherapeutics, and lack of effective targeted agents. One of the first major breakthroughs in the treatment of sarcomas was the use of imatinib to treat gastrointestinal stromal tumors (GISTs). Since then, advanced molecular techniques and genetic profiling have revolutionized the approach to sarcoma classification, diagnosis, prognosis and, most importantly, treatment. As the sarcoma genetic database continues to expand, the basis for how we classify, diagnose, and treat these challenging malignancies will be redefined. The overall goal of these types of techniques has been to determine a molecular blueprint for each sarcoma subtype and discover actionable alterations that lend themselves to targeted therapies. Other important information derived from these large genomic databases includes biomarkers, prognostic indicators, and information regarding tumorigenesis. Eventually, advanced molecular techniques will provide a personalized-medicine approach that tailors each treatment regimen to the patient's own tumor genome.

Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

Colorectal cancer (CRC) is a significant global health challenge, marked by varying incidence and mortality rates across different regions. The pathogenesis of CRC involves multiple stages, including initiation, promotion, progression, and metastasis, influenced by genetic and epigenetic factors. The chaperone protein glucose-regulated protein 78 (GRP78), crucial in regulating the unfolded protein response (UPR) during endoplasmic reticulum (ER) stress, plays a pivotal role in CRC pathogenesis.

Background: Radiation-induced sarcoma (RIS) is an exceptionally rare occurrence following radiation therapy, and manifestation usually occurs after a several-year latency period. Herein, the authors report the development of a radiation-induced osteosarcoma of the frontoparietal calvaria following treatment for an oligodendroglioma in an 84-year-old woman.
Observations: The patient had been diagnosed with a grade III anaplastic oligodendroglioma when she was 78 years old.
Chondrosarcomas are the second most common primary bone sarcoma. Due to chondrosarcomas relative resistance to chemotherapy and radiation, surgical treatment has become the mainstay treatment option. The purpose of our study was to understand the proportion of patients in this population who undergo non-operative treatment options secondary to various reasons and analyze the difference in survival as well as patient and cancer specific characteristics between the two groups.
