Abstract

AIM:

To evaluate, in patients with locally advanced pancreatic carcinoma undergoing concomitant chemoradiation, the impact of pretreatment hemoglobin (Hb) concentration on the outcome in terms of clinical response, local control, metastasis-free survival, disease-free survival, and overall survival.

PATIENTS AND METHODS:

30 patients undergoing concomitant chemoradiation (5-fluorouracil [5-FU], 1,000 mg/m(2)/day, continuous i.v. infusion days 1-4 of radiotherapy) and external beam radiotherapy (50.4-59.4 Gy) were divided into two groups based on pretreatment median Hb value (11.5 g/dl). The potential prognostic factors examined besides Hb concentration were: tumor site (head vs body-tail), sex (female vs male), cN (cN0 vs nC1), dose of external beam radiotherapy (50.4 Gy vs 59.4 Gy), presence of jaundice at diagnosis (yes vs no), weight loss at diagnosis (> or = 5 kg vs < 5 kg), epigastric-lumbar pain at diagnosis (yes vs no), maximum tumor diameter (< 40 mm vs > or = 40 mm).

RESULTS:

Pretreatment Hb ranged between 9.6 and 15.0 g/dl. No statistically significant differences were observed as for clinical response and local control between patients with an Hb < or = 11.5 g/dl and those with an Hb > 11.5 g/dl. Metastasis-free survival was 5.1 months in patients with an Hb < or = 11.5 g/dl and 10.7 months in patients with an Hb > 11.5 g/dl (p = 0,010). Median actuarial disease-free survival was 5.1 and 10.2 months in patients with an Hb < or = 11.5 and > 11.5 g/dl, respectively (p = 0.026). Median actuarial overall survival was 7.5 and 10.3 months in patients with an Hb < or = 11.5 and > 11.5 g/dl; respectively (p = 0.039). On multivariate analysis, Hb concentration at diagnosis was the only factor prognostically correlated with metastasis-free survival (p = 0.026), disease-free survival (p = 0.032), and overall survival (p = 0.048).

CONCLUSION:

In a group of patients with locally advanced pancreatic carcinoma treated with chemoradiation, a significant correlation was observed between pretreatment Hb levels and metastasis-free survival, disease-free survival, and overall survival.
