Objective: To explore the value of MRI in the detection of bone metastases in newly diagnosed prostate cancer.
Material And Methods: MRI examinations of the axial skeleton in 76 patients with newly diagnosed prostate cancer were reviewed, and the relation of these findings to the serum level of prostate specific antigen (PSA) was examined.
Results: MRI indicated bone metastases in 26/76 patients (34%) in the entire study group, in 4/24 (17%) with serum PSA <20 ng/ml and in 22/52 (42%) with serum PSA >20 ng/ml.
Conclusions: These results suggest that MRI is a more sensitive indicator of suspected bone metastases than bone scintigraphy in the low range of serum PSA, but less sensitive in the high range. Further studies of MRI and bone scintigraphy in parallel in patients with serum PSA <20 ng/ml are needed to elucidate their relative value in the staging of patients with prostate cancer.

Purpose: Mammary carcinoma is comprised heterogeneous groups of cells with different metastatic potential. 4T1 mammary carcinoma cells metastasized to heart (4THM), liver (4TLM) and brain (4TBM) and demonstrate cancer-stem cell phenotype. Using these cancer cells we found thatTGF-β is the top upstream regulator of metastatic process.

Ewing sarcoma family tumors (ESFT) pose diagnostic challenges, which largely depend on the primary site of involvement and tumor stage. Despite advancements in treatment, metastatic ESFTs remain associated with poor outcomes. This case describes a 21-year-old woman who, in July 2022, presented with a left breast mass identified through ultrasound and CT scan, along with abdominal distention.

A 65-year-old man was admitted for a tissue biopsy of suspected right middle and lower lobe lung cancer with multiple bone metastases. During hospitalization, he started to cough up blood, which recurred after intubation. The patient experienced asphyxia, which led to cardiopulmonary arrest, but was successfully resuscitated.

Osteosarcoma, the most common primary bone tumor in young individuals, frequently metastasizes hematogenously to the lungs, necessitating pulmonary metastasectomy as a common surgical procedure. While sublobar and lobar resections are accepted approaches, pneumonectomy is considered a major intervention. In this report, we present 2 intriguing cases of patients who underwent pneumonectomy for pulmonary osteosarcoma metastases, emphasizing the challenges of careful patient selection and surgical planning.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.
Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.
