Postoperative hyperphosphatemia significantly associates with adverse survival in colorectal cancer patients.

ABSTRACT: Hyperphosphatemia has been implicated in the development and treatment of various cancers. However, whether it can be used as a direct prognostic marker of colorectal cancer (CRC) has remained unexplored. Given new insights into the importance of hyperphosphatemia in CRC, we sought to evaluate the association of hyperphosphatemia with the clinical outcomes of this disease.In a retrospective analysis of a well-characterized clinic-based cohort with 1241 CRC patients, we assessed the association of postoperative hyperphosphatemia with patient overall survival.Postoperative hyperphosphatemia measured within the first month after surgery was significantly associated with CRC survival. Compared to patients with a normal phosphate level, those with hyperphosphatemia exhibited a significant unfavorable overall survival with a hazard ratio (HR) of 1.84 (95% confidence interval [CI] 1.49-2.29, P?=?2.6?×?10(-8) (log-rank P?=?1.2?×?10(-7) ). Stratified analyses indicated the association was more pronounced in patients with colon (HR?=?2.00, 95% CI 1.57-2.56, P?=?3.17?×?10(-8) ) but not rectal cancer (HR?=?0.96, 95% CI 0.58-1.59, P?=?0.889) (P interaction?=?0.023), as well as in those not receiving chemotherapy (HR?=?2.15, 95% CI 1.59-2.90, P?=?6.2?×?10(-7) ) but not in those receiving chemotherapy (HR?=?1.30, 95% CI 0.92-1.82, P?=?0.136) (P interaction?=?0.012). Flexible parametric survival model demonstrated that the increased risk for death conferred by postoperative hyperphosphatemia persisted over 150 months after surgery.Our data indicated that postoperative hyperphosphatemia might be used as a prognostic marker of CRC patients after surgery. Since phosphate level is routinely tested in clinics, it may be incorporated into clinical models to predict CRC survival.

Project description:ObjectivePlatelets have been implicated in cancer metastasis and prognosis. No population-based study has been reported as to whether preoperative platelet count directly predicts metastatic recurrence of colorectal cancer (CRC) patients.DesignUsing a well-characterized cohort of 1,513 surgically resected CRC patients, we assessed the predictive roles of preoperative platelet count in overall survival, overall recurrence, as well as locoregional and distant metastatic recurrences.ResultsPatients with clinically high platelet count (≥400 × 10(9)/L) measured within 1 month before surgery had a significantly unfavorable survival (hazard ratio [HR] = 1.66, 95 % confidence interval [CI] 1.34-2.05, P = 2.6 × 10(-6), P(log rank) = 1.1 × 10(-11)) and recurrence (HR = 1.90, 1.24-2.93, P = 0.003, P(log rank) = 0.003). The association of platelet count with recurrence was evident only in patients with metastatic (HR = 2.81, 1.67-4.74, P = 1.1 × 10(-4), P(log rank) = 2.6 × 10(-6)) but not locoregional recurrence (HR = 0.59, 95 % CI 0.21-1.68, P = 0.325, P(log rank) = 0.152). The findings were internally validated through bootstrap resampling (P < 0.01 at 98.6 % of resampling). Consistently, platelet count was significantly higher in deceased than living patients (P < 0.0001) and in patients with metastatic recurrence than locoregional (P = 0.004) or nonrecurrent patients (P < 0.0001). Time-dependent modeling indicated that the increased risks for death and metastasis associated with elevated preoperative platelet counts persisted up to 5 years after surgery.ConclusionOur data demonstrated that clinically high level of preoperative platelets was an independent predictor of CRC survival and metastasis. As an important component of the routinely tested complete blood count panel, platelet count may be a cost-effective and noninvasive marker for CRC prognosis and a potential intervention target to prevent metastatic recurrence.

Project description:ImportanceWhile the incidence of early-onset metastatic colorectal cancer (mCRC) has been increasing, studies on the age-related disparity in this group of patients are limited.ObjectiveTo evaluate the association of age with treatment-related adverse events and survival in patients with mCRC and explore the potential underlying factors.Design, setting, and participantsThis cohort study included 1959 individuals. Individual data on 1223 patients with mCRC who received first-line fluorouracil and oxaliplatin therapy in 3 clinical trials, and clinical and genomic data of 736 patients with mCRC from Moffitt Cancer Center were used to assess genomic alterations and serve as an external validation cohort. All statistical analyses were conducted from October 1, 2021, through November 12, 2022.ExposuresMetastatic colorectal cancer.Main outcomes and measuresSurvival outcomes and treatment-related adverse events were compared among patients in 3 age groups: younger than 50 (early onset), 50 to 65, and older than 65 years.ResultsIn the total population of 1959 individuals, 1145 (58.4%) were men. Among 1223 patients from previous clinical trials, 179 (14.6%) in the younger than 50 years group, 582 (47.6%) in the 50 to 65 years group, and 462 (37.8%) in the older than 65 years group had similar baseline characteristics except for sex and race. The younger than 50 years group had significantly shorter progression-free survival (PFS) (hazard ratio [HR], 1.46; 95% CI, 1.22-1.76; P < .001) and overall survival (OS) (HR, 1.48; 95% CI, 1.19-1.84; P < .001) compared with the 50 to 65 years group after adjustment for sex, race, and performance status. Significantly shorter OS in the younger than 50 years group was confirmed in the Moffitt cohort. The younger than 50 years group had a significantly higher incidence of nausea and vomiting (69.3% vs 57.6% [50-65 years] vs 60.4% [>65 years]; P = .02), severe abdominal pain (8.4% vs 3.4% vs 3.5%; P = .02), severe anemia (6.1% vs 1.0% vs 1.5%; P < .001), and severe rash (2.8% vs 1.2% vs 0.4% P = .047). The younger than 50 years group also had earlier onset of nausea and vomiting (1.0 vs 2.1 vs 2.6 weeks; P = .01), mucositis (3.6 vs 5.1 vs 5.7 weeks; P = .05), and neutropenia (8.0 vs 9.4 vs 8.4 weeks; P = .04), and shorter duration of mucositis (0.6 vs 0.9 vs 1.0 weeks; P = .006). In the younger than 50 years group, severe abdominal pain and severe liver toxic effects were associated with shorter survival. The Moffitt genomic data showed that the younger than 50 years group had a higher prevalence of CTNNB1 mutation (6.6% vs 3.1% vs 2.3%; P = .047), ERBB2 amplification (5.1% vs 0.6% vs 2.3%; P = .005), and CREBBP mutation (3.1% vs 0.9% vs 0.5%; P = .05), but lower prevalence of BRAF mutation (7.7% vs 8.5% vs 16.7%; P = .002).Conclusions and relevanceIn this cohort study of 1959 patients, those with early-onset mCRC showed worse survival outcomes and unique adverse event patterns, which could be partially attributed to distinct genomic profiles. These findings may inform individualized management approaches in patients with early-onset mCRC.
