Effects of lenalidomide on the bone marrow microenvironment in acute myeloid leukemia: Translational analysis of the HOVON103 AML/SAKK30/10 Swiss trial cohort.

This translational study aimed at gaining insight into the effects of lenalidomide in acute myeloid leukemia (AML). Forty-one AML patients aged 66 or older of the Swiss cohort of the HOVON-103 AML/SAKK30/10 study were included. After randomization, they received standard induction chemotherapy with or without lenalidomide.

Pure intraductal carcinoma of the parotid gland: Cytologic findings on FNA sample. Report of one case.

One case of intraductal carcinoma of the parotid gland in a 67-year-old male patient is here introduced. The patient, who had a one-year history of a parotid mass, had undergone ultrasound and MRI examination that disclosed a 13x4x3 mm well delimited nodular mass of the accessory lobe of his left parotid gland. Ultrasound-guided Fine Needle Aspiration (FNA) had been performed by the clinician.

Impact of preoperative radiotherapy on survival in locally advanced rectal cancer: an observational population-based study from the South of Switzerland.

Preoperative radiotherapy (RT) followed by surgery is widely accepted in the treatment of locally advanced rectal cancer (LARC). This study aimed to estimate at the population-based level the impact of preoperative RT on overall survival (OS) and cancer-specific survival (CSS) in LARCs diagnosed in Southern Switzerland between 1996 and 2007. All patients with LARC were selected from the Ticino Cancer Registry database.

The RET/PTC oncogene is frequently activated in oncocytic thyroid tumors (Hurthle cell adenomas and carcinomas), but not in oncocytic hyperplastic lesions.

Hurthle cell adenomas and carcinomas, characterized by the presence of oncocytic cells, are unusual thyroid neoplasms, the treatment of which is still controversial. We analyzed specimens from 49 patients with oncocytic cell nodular lesions including 20 adenomas, 19 carcinomas, and 10 hyperplasias for RET/PTC (papillary thyroid carcinoma) activation, which is the most frequent genetic alteration in PTCs. RET/PTC activation was detected in a significant number of cases of Hurthle cell adenomas and carcinomas, but in 0 of 10 patients with hyperplastic nodules.
