This study was to investigate a better way to detect and differentiate primary,residual,recurrent naso-pharyngeal carcinoma(NPC)lesions post-radiotherapy in patients with NPC by means of routine computed tomography(CT)in combination with 99Tcm-sestamibi single photon emission computed tomography(99Tcm-MIBI SPECT).Forty-eight patients with histologically conﬁrmed primary NPC underwent 99Tcm-MIBI SPECT at the 3rd month before and after radiotherapy,and at the 6th month after *** patients had contempora-neous CT *** results and/or clinical follow-up data(over 18 months)were used as the golden standard for evaluating residual/recurrent *** radioactive count ratio of nasopharynx to scalp was obtained as the MIBI uptake index(MUI).Receiver operating characteristic analysis was employed to deﬁne the cut-off value of MUI for *** MUI 2.15 as the cut-off point,the accuracy for detecting primary NPC was 94.12%.The mean MUI in the local-regional of the nasopharynx in such negative cases was 1.21�0.12 at the 3rd month,while the mean MUI was higher in the other 15 patients with histologically conﬁrmed recurrent/residual lesions(MUI=1.40�0.16,t=4.71,P<0.001).The optimal cut-off point of 1.33 of MUI was deﬁned with 89.58%accuracy for differentiating residual/recurrent lesions from the benign process post radiotherapy,while CT evaluations showed an accuracy of 81.25%.A combination of CT and 99Tcm-MIBI SPECT for 37 NPC patients with congruent results showed an accuracy of 97.30%for differentiating residual/recurrent NPC from benign lesions.99Tcm-MIBI SPECT plays a role in evaluating residual/recurrent lesions *** combination of CT and 99Tcm-MIBI SPECT can give more accurate diagnosis in the follow-up of NPC.

Esophageal cancer (EC) is one of the most deadly malignant diseases. Several studies revealed that variations of the phospholipase C epsilon 1 (PLCE1) gene were associated with EC susceptibility. PLCE1 is located downstream of the epidermal growth factor receptor (EGFR) pathway. Presently, the single nucleotide polymorphisms (SNPs) of EGFR/PLCE1 genes and their associations with EC survival remain unclea匚 In this study, the associations between genetic variants in the EGFR/PLCE1 pathway and prognosis in 124 esophageal squamous cell carcinoma (ESCC) patients with radical resection were explored. The results showed that CC genotype of both PLCE1 rsl7109671 and EGFR rs2072454 was associated with ESCC prognosis. Multivariate analysis revealed that patients with the two unfavorable genotypes had the worst overall survival (OS) or disease-free survival (DFS)(HR=6.099, 95%CI=1.903-19.552;HR=3.994, 95%CI=1.49-10.702, respectively). Additionally, combination of SNPs and tumor stage could better predict OS (for AUC, 0.774 vs. 0.709) and PFS (for AUC, 0.773 vs. 0.704) than tumor stage *** conclusion, genetic variants of the EGFR/PLCE1 may be predictors of the prognosis of ESCC after surgery. The individuals with the CC genotype of PLCE1 rsl7109671 and EGFR rs2072454 should receive more aggressive treatments.

AIM: To examine the predictive effects of baseline serum bilirubin levels and UDP-glucuronosyltransferase(UGT) 1A1*28 polymorphism on response of colorectal cancer to irinotecan-based ***: The present study was based on a prospective multicenter longitudinal trial of Chinese metastatic colorectal cancer(m CRC) patients treated with irinotecan-based chemotherapy(NCT01282658). Baseline serum bilirubin levels, including total bilirubin(TBil) and unconjugated bilirubin(UBil), were measured,and genotyping of UGT1A1*28 polymorphism was performed. Receiver operating characteristic curve(ROC) analysis was used to determine cutoff values of TBil and UBil. The TBil values were categorized into > 13.0 or ≤ 13.0 groups; the UBil values were categorized into > 4.1 or ≤ 4.1 groups. Combining the cutoff values of TBil and UBil, which was recorded as Co Bil, patients were classified into three groups. The classifier's performance of UGT1A1*28 and Co Bil for predicting treatment response was evaluated by ROC analysis. Associations between response and Co Bil or UGT1A1*28 polymorphism were estimated using simple and multiple logistic regression models. RESULTS: Among the 120 m CRC patients, the serum bilirubin level was significantly different between the UGT1A1*28 wild-type and mutant genotypes. Patients with the mutant genotype had an increased likelihood of a higher TBil(P = 0.018) and a higher UBil(P = 0.014) level compared with the wild-type genotype. Patients were stratified into three groups based on Co Bil. Group 1 was patients with TBil > 13.0 and UBil > 4.1; Group 2 was patients with TBil ≤ 13.0 and UBil > 4.1; and Group 3 was patients with TBil ≤ 13.0 and UBil ≤ 4.1. Patients in Group 3 had more than a 10-fold higher likelihood of having a response in the simple(OR = 11.250; 95%CI: 2.286-55.367; P = 0.003) and multiple(OR = 16.001; 95%CI: 2.802-91.371; P = 0.002) analyses compared with the Group 1 individuals.
