Neoadjuvant Lu-PSMA-I&T Radionuclide Treatment in Patients with High-risk Prostate Cancer Before Radical Prostatectomy: A Single-arm Phase 1 Trial.

Background: High-risk localized prostate cancer (HRLPC) has a substantial risk of disease progression despite local treatment. Neoadjuvant systemic therapy before definitive local therapy may improve oncological outcomes by targeting the primary tumor and micrometastatic disease.

Objective: To evaluate whether a lutetium-177 prostate-specific membrane antigen radioligand (LuPSMA) can be safely administered to patients with HRLPC before robot-assisted radical prostatectomy (RARP) and to describe immediate oncological outcomes.

Axillary Lymph Nodes Hypermetabolism After BNT162b2 mRNA COVID-19 Vaccination in Cancer Patients Undergoing 18F-FDG PET/CT: A Cohort Study.

Purpose: Recognition of the pattern of FDG uptake in hypermetabolic axillary lymph nodes (HALs) and association with recent messenger RNA (mRNA) vaccination are important to prevent patient anxiety and further needless examinations or costly biopsies in cancer patients.

Materials And Methods: This study was a retrospective cohort study in a single tertiary care institution. We investigate the occurrence and pattern of HAL on FDG PET/CT scans from 650 consecutive cancer patients with recent BNT162b2 mRNA COVID-19 vaccination.

Unilateral lower limb rest tremor is not necessarily a presenting symptom of Parkinson's disease.

Lower leg rest tremor is an uncommon symptom of neurological disease. Review of the files of 16 patients who presented with lower leg tremor (average age 58 +/- 16 years; average disease duration 6.8 +/- 8.

Short- and long-term outcome of lung volume reduction surgery. The predictive value of the preoperative clinical status and lung scintigraphy.

The NETT study assessed the benefits of lung volume reduction surgery (LVRS) versus medical treatment. However, data is available only on the early outcome of LVRS (24 months). We evaluate the factors affecting the outcome at one-year and up to 6 years after LVRS.

Lymphatic drainage to the popliteal basin in distal lower extremity malignant melanoma.

Unlabelled: Hypotheses Melanoma of the distal lower extremity may drain to the popliteal basin. Drainage pathways and retrieval of the popliteal sentinel nodes may affect patient outcome.

Design: Retrospective analysis of popliteal involvement in patients with stage IB or higher melanoma, operated on from August 1, 1993, to July 31, 2003.

Non-resectable slow-growing meningiomas treated by hydroxyurea.

Purpose: To test the benefit of hydroxyurea in the treatment of recurrent and non-resectable slow-growing meningiomas.

Methods: Twelve patients with regrowing non-malignant meningiomas, were enrolled for a protocol of 2 years with continuous chemotherapy with hydroxyurea, 20 mg/kg/day. Response to treatment was evaluated both clinically and by diagnostic imaging using computed tomography (CT) and 201-Thallium single photon emission CT.

Patterns of papillary muscle ischemia in myocardial PET.

Purpose: Conventional nuclear medicine equipment lacks sufficient spatial resolution to reliably visualize the papillary muscles (PM). Positron emission tomography (PET), however, can adequately visualize these structures using various positron emitters.

Methods And Patients: We present various patterns of PM observed on myocardial PET imaging in 4 patients.
