Unusual small bowel metastatic localization in a castration-resistant prostate cancer patient
نویسندگان
چکیده
• The availability of active new drugs has changed the natural history of advanced castration-resistant prostate cancer, significantly improving overall survival and thus leading to an increased risk of observing metastases in atypical sites. • Bone and lymph nodes are usually the most frequent sites for distant metastases arising from prostate cancer. Visceral metastases are rare and when they occur, they usually involve the liver and lungs. • The gastrointestinal (GI) tract is usually directly invaded from adjacent organs or enlarged lymph nodes. Hematogenous or lymphatic spread from prostate cancer to GI tube is uncommon, but the incidence seems to be increasing. • The presenting symptoms of GI metastases, such as nausea, vomiting and abdominal pain and body weight loss are usually nonspecific, and all of them are often related to anticancer treatments or progressive disease. • In patients with a history of prostate cancer and new-onset GI symptoms, GI metastases should be considered in the differential diagnosis.

The Iranian Society of Nuclear Medicine practical guideline on radioligand therapy in metastatic castration-resistant prostate cancer using 177Lu-PSMA
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with co...
متن کاملSingle Orbital Metastasis in Castration-Resistant Prostate Cancer
Introduction: Orbital metastasis of prostate cancer (PC) is very rare and even more unique in castration-resistant PC (CRPC). In this scenario, choline positron emission tomography/computed tomography (choline PET/CT) is the gold-standard restaging method of choice available in our setting, and new anti-androgens treatments show improvement in overall survival. Case presentation: We report the...

متن کاملProstate-specific antigen doubling time and response to cabazitaxel in a hormone-resistant metastatic prostate cancer patient
We report a case of metastatic castration-resistant prostate cancer, who received prior treatment with docetaxel and was then given cabazitaxel as salvage therapy. The patient was monitored by prostate-specific antigen doubling time and prostate-specific antigen absolute value. The prostate-specific antigen doubling time was found to be a good response predictor in the patient.
