Preoperative thrombocytosis is associated with survival after surgery for colorectal cancer.
ABSTRACT OBJECTIVE: To evaluate the influence of preoperative thrombocytosis on survival after surgery in patients with colorectal cancer (CRC). METHODS: Four hundred fifty-three patients who had undergone CRC surgery were retrospectively identified from institutional database. On the basis of receiver operating characteristic (ROC) curve analysis, they were classified into two groups: Group A, with a preoperative platelet count of ≤300 (×10(9) /L), and Group B, with a preoperative platelet count of >300 (×10(9) /L). Uni- and multivariate analyses were performed to evaluate the relationship to overall survival. Kaplan-Meier analysis and log rank test were used to compare the survival curves between groups A and B. RESULTS: There was a significant difference in overall survival between the two groups (P = 0.007). Multivariate analysis of selected preoperative clinicolaboratory characteristics showed that overall survival was associated with the platelet count (Group A/B) (odds ratio, 1.642; 95% CI, 1.025-2.629; P = 0.039) as well as the number of tumors (1/≥2), and the serum levels of C-reactive protein (CRP) and carcinoembryonic antigen (CEA). CONCLUSION: Preoperative thrombocytosis is associated with survival after surgery in CRC patients, and is able to divide such patients into two independent groups before surgery. J. Surg.

ABSTRACT: Systemic inflammatory response (SIR) has actually been shown as an important prognostic factor associated with lower postoperative survival in several types of cancer. Thus, the challenge for physicians is to find specific, low-cost, and highlyreliable inflammatory markers, clearly correlated with prognosis and able to preoperatively stratify patient's risk. Inflammation is a promising target to improve perioperative outcome, and data show that anti-inflammation techniques have a great potential in the perioperative period of cancer surgery. Inflammation scores could be useful to stratify patients with a potential better response to anti-inflammation strategies. Furthermore, inflammation scores could prevent failure of clinical trials by a better definition of patients to be included in such trials; inflammation scoring could clarify the real role of different drugs and techniques on outcome after cancer surgery, defining if different therapies are required for different patients. The role of this review is to focus on the currently available scores, in order to clarify their rationale and to analyze the actual evidence and limits, providing physicians with an updated overview of the possible inflammation-based prognostic scores for cancer patients undergoing surgery.BioMed Research International 01/2014; 2014:142425. · 2.71 Impact Factor

ABSTRACT: Background:This study investigated the usefulness of a novel inflammation-based prognostic system, named the COP-NLR (COmbination of Platelet count and Neutrophil to Lymphocyte Ratio), for predicting the postoperative survival of patients with colorectal cancer (CRC).Methods:The COP-NLR was calculated on the basis of data obtained on the day of admission: patients with both an elevated platelet count (>30 × 10(4) mm(-3)) and an elevated NLR (>3) were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively.Results:Four-hundred and eighty patients were enrolled. Multivariate analysis of clinical characteristics selected by univariate analysis showed that the COP-NLR (1, 2/0) (odds ratio, 0.464; 95% confidence interval, 0.267-0.807; P=0.007) had an association with cancer-specific survival, along with pathology, lymph node metastasis, the serum levels of carcinoembryonic antigen, C-reactive protein and albumin, and the Glasgow Prognostic Score. Kaplan-Meier analysis and log-rank test revealed that the COP-NLR was able to divide such patients into three independent groups (P<0.001).Conclusion:The COP-NLR is considered to be a useful predictor of postoperative survival in patients with CRC.British Journal of Cancer advance online publication, 2 July 2013; (2013) 0, 000-000. doi:10.1038/bjc.2013.350 www.bjcancer.com.British Journal of Cancer 07/2013; · 5.08 Impact Factor
