Patterns of cervical node metastases from squamous carcinoma of the oropharynx and hypopharynx.

摘要: A retrospective review of 333 previously untreated patients from 1965 to 1986, with primary squamous cell carcinoma the oropharynx or hypopharynx, was undertaken ascertain prevalence neck node metastases by level. The underwent 344 classical radical dissections. Patients were grouped clinical status at time dissection: elective dissection in N0 (N = 71), and immediate therapeutic N+ 259). Detailed analysis performed for each group based on specific site. This revealed a predominance levels II, III, IV both oropharyngeal hypopharyngeal primaries. Isolated "skip" outside occurred only 1 patient (0.3%). Otherwise, level I V involvement always associated nodal other (ie, N2 disease). These data support trend toward selective limited (anterior modified) patients. Furthermore, they provide foundation planning future prospective trials assess efficacy modifications extent carcinomas hypopharynx.
