AI Article Synopsis
- Malignant transformation from benign cartilage-forming bone tumors is uncommon but can occur, with a studied rate of 5.1% over an average follow-up of 57.3 months.
- A retrospective analysis of 627 cases from 1986 to 2004 identified 32 patients, primarily with solitary or multiple osteochondromas, who developed malignant tumors, mostly chondrosarcomas.
- Close monitoring and early intervention are crucial for orthopedic surgeons treating patients with benign bone tumors, as 15.6% of the affected patients experienced recurrence or metastasis.
Article Abstract
Background: Secondary malignancies arising from benign bone tumors are rare. Their recognition and diagnosis are difficult, and their slow growth and late recurrence require long-term follow-up. In this study, malignant transformation rates of various histological types of benign cartilage-forming bone tumors in large series were evaluated.
Methods: Between 1986 and 2004, a retrospective analysis of 627 cartilage-forming benign bone tumors revealed that 32 patients had malignant transformation. Of the 32 patients, 14 had solitary osteochondromas, 10 had multiple osteochondromas, 6 had a solitary enchondroma, 1 had Ollier's disease, and 1 had Maffucci's syndrome. The patient with Ollier's disease had two chondrosarcomas, and one patient with multiple osteochondroma had three chondrosarcomas. The cases were included in the study only when complete clinical documentation, radiological records, and histological analyses were available.
Results: The rate of malignant transformation for cartilage-originating tumors was 5.1% (solitary osteochondromas 4.2%, multiple osteochondromas 9.2%, solitary enchondromas 4.2%). The average time between the initial diagnosis and malignant transformation was 9.8 years. The most common site of involvement was the proximal portion of the femur. The tumors generally were well differentiated. The mean follow-up period was 57.3 months. Five patients (15.6%) died of tumor recurrence or metastasis at an average of 20.6 months. One patient is alive with tumor at 104 months.
Conclusions: Cartilage-forming benign bone tumors are rather prone to undergo malignant transformation. Although malignant transformation of a benign bone tumor is a rarely encountered situation, orthopedic surgeons should be cautious while following patients with a benign bone neoplasm. Early recognition and appropriate surgical treatment are required to achieve successful outcomes. The rate of local recurrence in secondary chondrosarcomas depends not only on adequate surgical treatment but also on the localization and histological grade.

Background And Aims: Oncogenic KRAS mutations are present in approximately 90% of pancreatic ductal adenocarcinoma (PDAC). However, Kras mutation alone is insufficient to transform precancerous cells into metastatic PDAC. This study investigates how KRAS-mutated epithelial cells acquire the capacity to escape senescence or even immune clearance, thereby progressing to advanced PDAC.

Background: Even a gross total resection of a benign epidermoid tumor (ET) carries a high risk of recurrence. The management strategy mostly involves redo surgical excision but at a significant cost of morbidity and mortality. The role of adjuvant radiation therapies in this scenario is still undefined.

Classification of adenocarcinoma (AC) and squamous cell carcinoma (SCC) poses significant challenges for cytopathologists, often necessitating clinical tests and biopsies that delay treatment initiation. To address this, we developed a machine learning-based approach utilizing resected lung-tissue microbiome of AC and SCC patients for subtype classification. Differentially enriched taxa were identified using LEfSe, revealing ten potential microbial markers.

Cancer remains as a global health threat, with the incidence of breast cancers keep increasing. Dis-regulated redox homeostasis has been considered with essential roles for tumor initiation and progression. Using triple negative breast cancers, the most malignant subtype of breast cancers, as the tumor model, we explored the roles of the anti-oxidant spermidine, the pro-oxidative tool cold atmospheric plasma (CAP), and their combined use in cancer growth, anti-oxidative ability and cell cycle.

Introduction And Importance: Retiform hemangioendothelioma(RH) is a rare vascular tumor affecting patients over a wide age range without a gender predilection; only about 50 cases have been described so far.
Case Presentation: We report a case of submandibular retiform hemangioendothelioma in a 58-year-old woman who had been diagnosed with RH 20 years ago and had experienced recurrence four times during the past 20 years. This will increase the limited number of such cases in the hope of gaining a better understanding of this rare type of tumor.
