Abstract (sommario):

Objective. To determine the value of 18F-FDG PET/CT in detection of bone marrow (BM) metastasis in breast cancer which is considered an early stage of bone metastasis. Patients and Methods. Retrospectively, breast cancer patients with bone metastasis were included. BM metastasis was considered if the lesion was PET positive/CT occult while bone metastasis was considered if the lesion was PET positive/ CT positive. BM metastases were observed sequentially on F18-FDG PET/CT. Results. We included 35 patients. Eighteen patients (51%) had BM metastases in addition to other bone metastases. BM metas

Abstract (sommario):

Introduction: Uveal metastasis is the most common form of intraocular malignancy. Most uveal metastais occur in the posterior uvea, and iris metastasis are relatively rare. They may present as stromal nodules or ill-defined iris thickening, or they may be associated with atypical features such as pain or iridocyclitis. Objective and Methodes: We report the case of a 54-year-old patient whose ophthalmological examination revealed a relapse of her neoplastic disease. We emphasize the importance of a detailed medical history and a systematic general examination to establish an accurate diagnosis

This study aimed to investigate the impact of distinct metastasis patterns on the overall survival (OS) of individuals diagnosed with organ metastatic lung squamous cell carcinoma (LUSC). OS was calculated using the Kaplan–Meier method, and univariate and multivariate Cox regression analyses were conducted to further assess prognostic factors. A total of 36,025 cases meeting the specified criteria were extracted from the Surveillance, Epidemiology, and End Results database. Among these patients, 30.60% (11,023/36,025) were initially diagnosed at stage IV, and 22.03% (7936/36,025) of these indi

Abstract (sommario):

Cancer metastasis requires a series of sequential steps, each of which is rate limiting. Neoplasms are biologically heterogeneous, and the process of metastasis is highly selective. Multiple metastases often differ in biologic characteristics and can change during the course of the disease. Clonal analysis of human melanoma suggest that systemic, physiologic signals can be recognized by neoplastic cells. Brain metastases are particularly common in patients with metastatic melanoma. The blood brain barrier does not prevent the invasion of the brain parenchyma by circulating metastatic cells, an

AbstractMetastatic tumours in major salivary glands are uncommon with a higher incidence of primary sites from the head and neck. The lungs and breast are the common primary sites, while metastases from the kidney are very rarely found. The authors describe a case of renal clear-cell carcinoma with metastastis to the parotid gland. The incidence of a metastasis in the parotid gland from a primary renal carcinoma, even if rare, should not be overlooked in making a correct differential diagnosis with acinic cell carcinoma and monomorphic clear cell adenoma.

Abstract (sommario):

Brain metastases in sarcoma are exceedingly rare, with few published series documenting ranges from 1% to 8%. This study investigated the outcomes of sarcoma patients with brain metastases using a population-based analysis. This was a retrospective review of 5933 patients with high-grade sarcoma identified from the Surveillance, Epidemiology, and End Results database between 2010 and 2015. Of the eligible 5933 patients, 0.7% ( n = 44) had brain metastasis. Kaplan–Meier was used to estimate survival and follow-up (reverse Kaplan–Meier), and a multivariable Cox proportional hazards model analyze

To compare prognosis according to sites of bone metastasis, we defined two new terms in this study: ‘mesometastasis’ and ‘rhizometastasis’ as bone metastasis of ‘forearm or lower leg’ and ‘arm or thigh’, respectively.

Up to one quarter of lung cancers develop brain metastases and subsequent median overall survival is one year. Although clinical factors do not reliably predict brain metastasis development, DNA methylation signatures have been recently shown to predict outcomes in other cancers. It is hypothesized that DNA methylation signatures predicting brain metastasis development from lung cancer will be identified.

Renal cell carcinomas (RCCs) are known for their unpredictable metastatic pattern. We present the case of a 63-year-old woman who initially presented in 1992 with a metastasis in the left calcaneus that led to the discovery of RCC. In 1998, a new metastasis was found in the ovary. In 2008, the diagnosis of a gallbladder metastasis was made. All metastases were surgically removed; no additional systemic therapies were used. Aggressive surgical treatment can prolong the survival of patients with resectable metastases. Patterns of metastasis are discussed, and a brief review of the literature is

We used experimental metastasis mouse models and samples from patients with breast cancer to study metastases aggressiveness. We discovered that the aggressiveness of cancer cells in lung metastases was driven by an alternative translational program that was regulated by metabolite signaling. Strikingly, the identified molecular mechanism could be disrupted by repurposing a clinical approved inhibitor, which resul
