Epidemiology, treatment and outcomes of gastroenteropancreatic neuroendocrine neoplasms.

To investigate incidence, treatment patterns and outcomes of gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN) in the United States. The 2019 National Cancer Database was searched for adult GEP-NEN patients. Main outcomes included overall and site-specific incidence, treatment patterns, and overall survival (OS).

Treatment adherence and effectiveness in patients treated with carfilzomib-based therapy combinations for relapsed/refractory multiple myeloma in Germany: interim results from the non-interventional CARO study.

Therapy adherence can significantly influence the outcome of cancer patients. The prospective, non-interventional CARO study (NCT02970747) investigated adherence, effectiveness, and safety of carfilzomib in patients with relapsed/refractory multiple myeloma (RRMM) in the German real-world setting. In total, 359 patients were included at 69 sites.

Thiamine-Responsive Megaloblastic Anemia Syndrome Mimicking Myelodysplastic Neoplasm.

Introduction: Thiamine-responsive megaloblastic anemia syndrome (TRMA) is a rare autosomal recessive disease with a homozygous or compound-heterozygous mutation in the SLC19A2 gene characterized by megaloblastic anemia, diabetes mellitus (DM), and sensorineural hearing loss with onset in childhood. Folic acid and vitamin B12 in serum are normal with dysplastic erythropoiesis in the bone marrow often mimicking myelodysplastic neoplasms (MDS) as a potential differential diagnosis. Thiamine substitution leads to normalization of anemia, without effects on hearing loss or DM.

Renal tumor segmentation, visualization, and segmentation confidence using ensembles of neural networks in patients undergoing surgical resection.

Objectives: To develop an automatic segmentation model for solid renal tumors on contrast-enhanced CTs and to visualize segmentation with associated confidence to promote clinical applicability.

Materials And Methods: The training dataset included solid renal tumor patients from two tertiary centers undergoing surgical resection and receiving CT in the corticomedullary or nephrogenic contrast media (CM) phase. Manual tumor segmentation was performed on all axial CT slices serving as reference standard for automatic segmentations.

Stage IA papillary and chromophobe renal cell carcinoma: effectiveness of cryoablation and partial nephrectomy.

Objectives: To evaluate the effectiveness of cryoablation compared to partial nephrectomy in patients with stage IA papillary and chromophobe renal cell carcinoma (pRCC; chRCC).

Material And Methods: The 2004-2016 National Cancer Database was queried for adult patients with stage IA pRCC or chRCC treated with cryoablation or partial nephrectomy. Patients receiving systemic therapy or radiotherapy, as well as those with bilateral RCC or prior malignant disease were excluded.
