Exclusion of elective nodal irradiation is associated with minimal elective nodal failure in non-small cell lung cancer
BACKGROUND Controversy still exists regarding the long-term outcome of patients whose uninvolved lymph node stations are not prophylactically irradiated for non-small cell lung cancer (NSCLC) treated with definitive radiotherapy. To determine the frequency of elective nodal failure (ENF) and in-field failure (IFF), we examined a large cohort of patients with NSCLC staged with positron emission ...
متن کاملPostoperative elective nodal irradiation for squamous cell carcinoma of the head and neck: outcome and prognostic factors for regional recurrence.
BACKGROUND This study describes the results of elective irradiation in the N0 neck and tries to identify prognostic factors for regional recurrence. MATERIALS AND METHODS Between 1985 and 2000, 785 cN0 or pN0 necks were treated with elective nodal irradiation in 619 head and neck squamous cell carcinoma patients. RESULTS Regional control at 3 years was 94% in the cN0 (nondissected) neck com...
متن کاملEfficacy of elective nodal irradiation in skin squamous cell carcinoma of the face, ears, and scalp
BACKGROUND In patients at high risk for regional node metastasis from squamous cell carcinoma (SCC) of the skin of the face, ear, or scalp, radiotherapy to the regional nodes is an alternative to parotid or neck surgery. Data on the efficacy of elective nodal radiotherapy in this setting are scarce such that there is no publication specifically addressing the subject. The purpose of our study i...
متن کاملPatterns of nodal involvement for clinically N0 salivary gland carcinoma: refining the role of elective neck irradiation.
BACKGROUND The purpose of this study was to analyze the pattern of occult cervical lymph node metastasis among patients with clinically N0 salivary gland carcinoma. METHODS One hundred nineteen patients underwent primary surgery and ipsilateral neck dissection for clinically N0 carcinomas of the major and minor salivary glands. Eighty patients (67%) had parotid tumors. Distribution of T class...
متن کاملIpsilateral neck nodal status as predictor of contralateral nodal metastasis in carcinoma of tongue crossing the midline.
BACKGROUND In squamous cell carcinoma of the tongue, when lesions reach or cross the midline, there is a higher risk of contralateral nodal metastasis. Identifying factors that are associated with higher risk of nodal metastasis may help in optimizing the treatment. METHODS A retrospective analysis was conducted of all patients with squamous cell carcinoma of the tongue who had undergone bila...
