We hereby present a case of primary osteogenic sarcoma in the right breast of a 62-year-old woman with synchronous appearance of an invasive ductal carcinoma.

Endosonographic assessment of the response of rectal cancer to preoperative radiotherapy endosonographic assessment of the response of rectal cancer to preoperative radiotherapy.

Background/aims: The accuracy of endoluminal ultrasonographic restaging of rectal cancer after chemoradiation has not been extensively studied and its definitive clinical utility has yet to be defined. The aim of the present study is to assess the benefit of endoluminal ultrasonography with Doppler evaluation for rectal cancer restaging after preoperative radiotherapy.

Methodology: Twenty six patients (10 female, 16 males, mean age--58 years) with histologically proven rectal cancer underwent preoperative radiotherapy.
