Abstract

Objective To determine the overall survival of patients with advanced pancreatic cancer and evaluate factors that impact prognosis in a private cancer center.Methods Data from the Hospital Cancer Registry at Hospital Israelita Albert Einstein were retrospectively collected. The patients enrolled had metastatic cancer at diagnosis or earlier staging and subsequent recurrence. Cases of neuroendocrine tumors were excluded.Results A total of 65 patients were evaluated, including 63 with adenocarcinoma. The median overall survival for patients in all stages was 20.7 months (95%CI: 15.6-25.7), while the overall survival of metastatic disease was 13.3 months. Among the 33 cases with stage IV cancer, there was no evidence of a statistically significant association between median survival and CA19-9 dosage (p=0.212), tumor location (p=0.482), first treatment performed (p=0.337), lymphovascular invasion (p=0.286), and age (p=0.152). However, the number of lines of chemotherapy was significantly associated with survival (log-rank p=0.013), with an estimated median survival of 10.2 months for patients who received up to two lines of treatment and 23.5 months for those receiving more than two lines of chemotherapy.Conclusion The survival of patients treated was longer than that reported in the literature. The only statistically significant factor related to increased survival was higher number of lines of chemotherapy received. We believe that the higher socioeconomic status of patients surveyed in this study, as well as their greater access to treatment options, may have influenced their overall survival.

Attention Score in Context

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 16 September 2019.
All research outputs
#17,286,645
of 25,374,917 outputs
Outputs from Einstein (São Paulo)
#281
of 576 outputs
Outputs of similar age
#166,656
of 277,680 outputs
Outputs of similar age from Einstein (São Paulo)
#4
of 5 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 576 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one is in the 29th percentile – i.e., 29% 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 277,680 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one.
