Abstract

To identify prognostic factors in patients with parotid gland carcinomas who were treated at the Princess Margaret Hospital. Clinical outcome of two hundred fifteen patients with malignancies of the parotid gland was evaluated over a 16-year period. Two-hundred-fifteen patients with adenoid cystic carcinoma (n = 20), adenocarcinoma (n = 19), acinic cell carcinoma (n = 62), basal cell adenocarcinoma (n = 7), carcinoma-ex-pleomorphic adenoma (n = 18), mucoepidermoid carcinoma (n = 70) and salivary duct carcinoma (n = 19) have been included. The 5- and 10-year overall and disease-free survivals were 80.62 %/69.48 % and 74.37 %/62.42 %, respectively. Multivariable analysis showed that age greater than 60 years, advanced pN classification, histopathological grade and the presence of lymphovascular invasion significantly worsened overall and disease-free survival. Univariable analysis revealed periparotid lymph node involvement was associated with decreased overall (p < 0.0001) and disease-free survival (p < 0.0001). In addition to age, pN classification, histopathological grade, perineural invasion, and lymphovascular involvement, periparotid lymph node metastasis appears to be an important prognosticator in parotid gland malignancy.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 October 2015.
All research outputs
#15,349,419
of 22,831,537 outputs
Outputs from Journal of Otolaryngology -- Head & Neck Surgery
#185
of 448 outputs
Outputs of similar age
#166,883
of 284,657 outputs
Outputs of similar age from Journal of Otolaryngology -- Head & Neck Surgery
#4
of 18 outputs
Altmetric has tracked 22,831,537 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 448 research outputs from this source. They receive a mean Attention Score of 4.7. This one is in the 44th percentile – i.e., 44% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 284,657 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 32nd percentile – i.e., 32% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
