ASP was upregulated in CRC tissues, and greater activity correlated significantly with the absence of lymph node metastases and with better overall survival.
It was demonstrated that MDR1 expression present in an FNA from a lymph node metastasis of breast carcinoma could be attributed completely to the leukocytes present in this FNA, because MDR1 expression was no longer detectable after purification of the tumor cells.
We also found that the 3435TT genotype of MDR1 was associated with a lower risk of non-cardiac cancer (OR = 0.42; 95% CI = 0.23-0.79), middle-third cancer (OR = 0.36; 95% CI = 0.17-0.77), advanced cancer (OR = 0.31; 95% CI = 0.13-0.73), venous invasion (OR = 0.30; 95% CI = 0.10-0.91), and lymph node metastasis (OR = 0.28; 95% CI = 0.13-0.65).
The study evaluated the contribution of serum PS100 assay to the detection of lymph node metastases during the follow-up of patients previously treated for a malignant melanoma, in addition to (99m)Tc sestamibi (MIBI) scintigraphy and investigation for gene MDR1, in order to detect chemoresistance phenomena.
In this study, we investigated the usefulness of fluorodeoxyglucose positron emission tomography (FDG-PET) as a marker for lymph node metastasis, P-glycoprotein (P-gp) expression, and recurrence in ICC.
Several biomarkers were (ALDH1, Sox2, Oct4, ABCB5, AGR2 and TAZ) correlated with clinical characteristics of the tumor, such as staging, tumor size and lymph node metastasis.
In adenocarcinoma tissues, MRP-1 expression level was associated with the differentiation grade, TNM staging and whether there was lymph node metastasis (p<0.05 in all comparisons).
CD44v6 and ABCG2 expression was significantly associated with regional lymph node metastasis, pattern of invasion, depth of invasion, perineural invasion and local recurrence, respectively.
Immunohistochemistry (IHC) corroborated accumulation of poly-(ADP-ribose)-polymerase 1 and N-myc-downstream-regulated-gene 3, alpha/beta hydrolase domain-containing protein 11, and protein phosphatase slingshot homolog 3 in LNM.
In the present study, ABHD5 was overexpressed in endometrial cancer tissues, and its expression was closely correlated with the International Federation of Gynecology and Obstetrics (FIGO) stage and lymph node metastasis.
ACE and AT2R were significantly upregulated in tumors and metastases, and expressed in the lymph node metastases of 26 (58%) and 40 (89%) gastric cancer patients, respectively.
Our data suggest that the ACE gene polymorphisms may be associated with increased susceptibility to OPL and oral cancer and lymph node metastasis from oral cancer.
In breast cancer patients, no significant association was observed between the ACE genotypes and poor prognostic factors, such as negative hormone receptor status, histological grade, lymph node involvement, higher number of lymph node metastases, and c-erb B2 overexpression, except that tumor size greater than 2 cm is associated with DD genotype (p = 0.02).
CD10, CD13, and CD143 were significantly up-regulated in GCs and the lymph node metastases, confirming that they are important for the tumor cell biology.
Studies of the angiotensin converting enzyme (ACE) I/D polymorphism have provided evidence that the D/D genotype is associated with gastric tumor progression and numbers of lymph node metastases, but not with the overall risk of gastric cancer.
When the ACE genotype was included, the relative risk of having lymph node metastases increased considerably in AT1R+ tumors being heterozygous or homozygous for the ACE D allele (odds ratio, 19.00; 95% confidence interval, 1.45-248.24).
