A rare Ewing-like small round cell tumor in prostate: a case report and literature review
CONCLUSION: Because of its non-elevated serum PSA level, prostate SRCT is often ignored as a possibility of malignant tumor and regarded as benign prostatic hyperplasia (BPH). The possibility of prostate SRCT need to be considered if dysuria symptoms could not alleviate significantly after a period of oral treatment.PMID:38427070 | DOI:10.1007/s00432-023-05585-2 (Source: Clinical Prostate Cancer)

A radiotherapy community data-driven approach to determine which complexity metrics best predict the impact of atypical TPS beam modeling on clinical dose calculation accuracy
CONCLUSION: Extreme values for MLC offset and MLC transmission beam modeling parameters were found to most substantially impact the dose distribution of clinical plans and careful attention should be given to these beam modeling parameters. The mean MLC Gap and TGi complexity metrics were best suited to identifying clinical plans most sensitive to beam modeling errors; this could help provide focus for clinical QA in identifying unacceptable plans.PMID:38427776 | DOI:10.1002/acm2.14318 (Source: Clinical Prostate Cancer)

18F-FDG and 68Ga-PSMA PET/CT in Paratesticular Mesothelioma
Clin Nucl Med. 2024 Apr 1;49(4):332. doi: 10.1097/RLU.0000000000005123.ABSTRACTA 66-year-old man with local prostate adenocarcinoma underwent radical prostatectomy (Gleason score 3 + 4 = 7, pT2c) in 2016. Four years later, he presented with a hydrocele and cystic atypical change in the left scrotum and soft tissue in the left groin. Final histopathology revealed spermatic cord mesothelioma and left hemangiosis carcinomatosa. A bone biopsy of the sacrum revealed infiltrates of a prostatic adenocarcinoma with small cell neuroendocrine differentiation. Dual-tracer PET/CT imaging using 18F-FDG and 68Ga-PSMA was able to identif...

Increased Prostate-Specific Membrane Antigen Uptake in a Gallbladder Stone
Clin Nucl Med. 2024 Apr 1;49(4):344-345. doi: 10.1097/RLU.0000000000005121. Epub 2024 Feb 28.ABSTRACTAn Al 18F-prostate-specific membrane antigen (PSMA) Q PET/CT scan was performed in a 67-year-old man to identify any potential recurrent prostate cancer lesions, which revealed no recurrent or metastatic lesions. However, a large gallbladder stone with increased PSMA uptake was incidentally detected, which could be a potential pitfall in the interpretation of PSMA PET imaging.PMID:38427958 | DOI:10.1097/RLU.0000000000005121 (Source: Clinical Prostate Cancer)

Cutaneous Metastasis From Prostate Cancer on Posttherapeutic 177Lu-Prostate-Specific Membrane Antigen Scan
Clin Nucl Med. 2024 Feb 27. doi: 10.1097/RLU.0000000000005130. Online ahead of print.ABSTRACTIn this note, we aim to present a patient with a known case of prostate cancer with widespread metastasis to the skeleton and liver who has undergone several cycles of chemoradiotherapy. The patient received 2 doses of 177Lu-prostate-specific membrane antigen therapy, in which several zones of uptake were detected on the thoracic wall compatible with cutaneous metastatic lesions of prostate cancer.PMID:38409757 | DOI:10.1097/RLU.0000000000005130 (Source: Clinical Prostate Cancer)

68Ga-PSMA Uptake in the Testis: Two Different Patients With Two Different Diagnosis
Clin Nucl Med. 2024 Feb 27. doi: 10.1097/RLU.0000000000005128. Online ahead of print.ABSTRACTAlthough abnormal 68Ga-PSMA uptake in the prostate and its metastases can be seen in a variety of diseases, it is rare to see in the testis. In these 2 cases, 68Ga-PSMA PET/CT revealed unilateral 68Ga-PSMA uptake in the testis of 2 patients. One of these patients was diagnosed with testis metastases from prostate cancer after an orchiectomy. The other patient was diagnosed with an orchitis. 68Ga-PSMA uptake should be considered as an infection, as well as a malignancy in the initial differential diagnosis.PMID:38409760 | DOI:10.109...

Dual 177Lu-Prostate-Specific Membrane Antigen and 177Lu-DOTATATE Therapy in Metastatic Castration-Resistant Prostate Cancer With Neuroendocrine Differentiation
We present an 87-year-old man diagnosed with prostate cancer and neuroendocrine differentiation, posttherapy results to consecutive 177Lu-prostate-specific membrane antigen and 177Lu-DOTATATE. Despite hormonal therapy and chemoradiotherapy, the patient progressed rapidly, and multiple liver and bone metastases showed regression after 177Lu-prostate-specific membrane antigen and 177Lu-DOTATATE treatment. Prostate cancer with neuroendocrine differentiation is resistant to treatments; however, treatment with the combination of 177Lu-DOTATATE therapy may be promising.PMID:38409763 | DOI:10.1097/RLU.0000000000005131 (Source: Cl...

Radical prostatectomy cancer grade and percentage of Gleason pattern 4 estimated by global vs individual tumor grading correlate differently with the risk of biochemical recurrence in Grade Group 2 and 3 cancers
CONCLUSIONS: Grade Group, GP4%, and margin status derived by global vs individual tumor grading predict postoperative biochemical recurrence statistically significantly differently. This difference has important implications if results derived from cohorts graded using different methods are compared.PMID:38412318 | DOI:10.1093/ajcp/aqae003 (Source: Clinical Prostate Cancer)
