A retrospective survey of all cases of osteosarcoma of the femur and tibia treated at the major centres in the United Kingdom during 1952-9 was carried out in an attempt to assess the respective value of treatment by surgery and radiotherapy and the feasibility of a larger prospective study. Of the 192 patients available for the comparison, those treated by radiotherapy alone did least well. A combination of the two treatments-radiotherapy followed by amputation-produced better results, in terms of survival, than amputation alone; however, the comparatively small numbers involved and the inadequacy of information about the factors dictating the choice of treatment make firm conclusions impossible. A controlled clinical trial on a larger scale might provide answers to the outstanding questions.

Objective: The purpose of the study was to investigate the cytotoxicity, biocompatibility, and osteogenic effect of EndoSequence BCSealer HiFlow (BCH) and Bio-C Sealer (BCS) in osteosarcoma cells SAOS-2 compared with AH Plus Jet.
Materials And Methods: For cytotoxicity analysis, the [3-(4,5-dimethyl-thiazole)-2,5-diphenyltetrazolium bromide-MTT; Sigma/Aldrich] method was used after 24, 48, and 72 hours. For cellular bioactivity, alkaline phosphatase enzyme (ALP) was evaluated after 7 and 14 days.

Osteosarcoma is the most common bone tumor and a highly aggressive malignant neoplasm. This study aims to elucidate the role of lactylation-related genes (LRGs) in osteosarcoma, with the goal of improving prognostic accuracy and enhancing the efficacy of immunotherapy. Using public datasets, we integrated differential and correlated genes based on single-cell sequencing AUCell scores and performed enrichment analysis and risk model construction on these genes.

Osteosarcoma is medically defined as a bone-forming tumor with associated bone-degrading activity. There is a lack of knowledge about the network that generates the overproduction of bone. We studied the early stage of osteosarcoma development with mice enduring a periosteum injection of osteosarcoma cells at the proximal third of the tibia.

Introduction: Globally, lung cancer is one of the most commonly diagnosed cancers and continues to take the lead in cancer-related mortality rates. This study aims to provide the latest statistics on the clinical, histopathological, and epidemiological features of lung cancer patients who underwent surgical resection in referral hospitals in Southern Iran.
Method: In this retrospective study, records of all patients with operable primary and secondary lung cancer who underwent surgical resection of the lung in Shiraz hospitals, located in Southern Iran from November 2009 to May 2022 were screened.

Difficult airway management in oromaxillofacial tumor surgery poses significant challenges for anesthesiologists. We present two case reports of patients with mandibular malignant tumors and maxillary osteosarcoma who underwent surgery under general anesthesia. Preoperative assessment revealed a mass involving the right mandible, completely covering the inside of the mouth and invading the floor of the mouth in the first case, and a mass in the left maxilla extending to the zygomatic arch and orbital floor in the second case.
