Reduced SMAD4 expression was found in 60.8% of cases; it was significantly correlated with advanced stages and lymph node metastasis and showed trends of larger tumor size and lymphatic invasion.

Immunohistochemistry showed that the expression of SMAD4 in PDAC carcinoma tissue was significantly lower than that in normal pancreatic tissue, and negative SMAD4 expression was closely related to tumour diameter, staging, lymph node metastasis and differentiation.

Kaplan-Meier survival analysis showed that tumor size (P = 0.031), lymph node metastasis (P < 0.001), pathological stage (P < 0.001), P53(Mut) protein expression (P = 0.038), and loss of p16 or Smad4 expression (P < 0.001) were significantly associated with shorter overall survival(OS), whereas multivariate analysis indicated that lymph node metastasis (P = 0.014) and loss of p16 or Smad4 expression (P < 0.001) were independent prognostic factors.

In addition, loss of Smad4 staining was more likely to be found in older (OR = 1.69, 95% CI: 1.09-2.61; Pheterogeneity = 0.648) colorectal cancer patients with a late tumor stage (OR = 2.31, 95% CI: 1.71-3.10; Pheterogeneity = 0.218) and in gastric cancer patients with lymph node metastasis (OR = 2.11, 95% CI: 1.03-4.34; Pheterogeneity = 0.038).

The results indicated that the low expression of Smad4 mRNA in prostate cancer was associated with lymph node metastasis, preoperative prostate-specific antigen (PSA), and Gleason score.

Kaplan-Meier survival analysis showed that lymph node metastasis (P = 0.001), lymphatic invasion (P = 0.008), the tumor (T) factor (T3 vs. T1/T2, P = 0.004), loss of p16 immunolabeling (P = 0.029), and loss of Smad4/Dpc4 immunolabeling (P < 0.001) were significantly associated with shorter overall survival.

Immunohistochemical results revealed that the positive rate of deleted in pancreatic carcinoma locus 4 in normal tracheal-bronchial epithelium (89.5%, 17/19) was much higher than that in tumor tissues (63.5%, 33/52) (P < .05) and closely correlated with lymph node metastasis (P < .001).

Based on an analysis of 577 cases for which clinical outcome information was available, failure to express Smad2, pSmad2, or Smad4 was associated with advanced-stage disease, the presence of lymph node metastases, and a significantly shorter overall survival (median survival: 35 vs 58 months).
