We conducted a study to determine whether certain clinicopathologic factors are associated with a greater risk ([greater than or equal to] 20%) of neoplastic recurrence in patients with pN0 LCSE.
LCSE was defined as a tumor that originated in the supraglottis or glottis and extended to the subglottis more than 10 mm anteriorly or 5 mm posteriorly; pN0 was defined as representing resected cervical lymph nodes that were histologically free of metastatic neoplasm.
Included in this cohort was 1 patient with a history of definitive radiotherapy for stage I laryngeal glottic cancer who had undergone salvage laryngectomy with bilateral lymph node dissection for LCSE.
The level VI (prelaryngeal) node was removed when LCSE was detected before or during surgery, which occurred in 8 patients.
Survival according to the Kaplan-Meier analysis was estimated from the time of LCSE diagnosis until death or the date of the last follow-up.
The recurrence rate was 29% (2/7) when the LCSE was 10 mm or smaller and 27% (3/11) when it was larger than 10 mm.
By attaching the visual supercomputer's video output to ATM networks, EVL, LCSE
, NCSA, Argonne, and the University of Utah will develop remote steering capabilities for users with ATM access but no access to advanced graphics hardware.
The LCSE simulation used two 64-processor systems at the NCSA interconnected by 100 MB/sec HIPPI channels.
The enhanced PPM code created by Porter and the LCSE team employs a novel strategy for overcoming latency in parallel computing applications.
Rather than eliminating latency from the LCSE application, they hid it.
The actual results of the gas dynamics application obtained by the LCSE were substantial.
