PD-0048: Patterns of recurrence in electively irradiated lymph nodes after definitive IMRT for head and neck cancer

Patterns of recurrence and survival of head and neck adenoid cystic carcinoma after definitive resection.

OBJECTIVES/HYPOTHESIS To determine factors impacting recurrence and long-term survival of adenoid cystic carcinoma (ACC) of the head and neck after definitive resection. STUDY DESIGN Retrospective cohort study at an academic tertiary care hospital. METHODS Patients with ACC of the head and neck treated at our institution were reviewed. Those not receiving surgery, or with metastatic disease...

Lhermitte's Sign Developing after IMRT for Head and Neck Cancer

Background. Lhermitte's sign (LS) is a benign form of myelopathy with neck flexion producing an unpleasant electric-shock sensation radiating down the extremities. Although rare, it can occur after head and neck radiotherapy. Results. We report a case of Lhermitte's developing after curative intensity-modulated radiotherapy (IMRT) for a patient with locoregionally advanced oropharyngeal cancer....

Optimal timing of computed tomography for assessing lymph nodes after neoadjuvant chemoradiotherapy for rectal cancer

Background: This study assessed the optimal timing of computed tomography for detection of metastatic disease in locoregional lymph nodes in patients with rectal cancer who have undergone chemoradiotherapy. Materials and Methods: This observational retrospective study was performed in a single institution. All patients with locally advanced rectal cancer treated with chemoradiotherapy, followed...

Postoperative IMRT in head and neck cancer

BACKGROUND Aim of this work was to assess loco-regional disease control in head and neck cancer (HNC) patients treated with postoperative intensity modulated radiation therapy (pIMRT). For comparative purposes, risk features of our series have been analysed with respect to histopathologic adverse factors. Results were compared with an own historic conventional radiation (3DCRT) series, and with...
