Brief Summary

Colorectal cancer tissue sections were obtained according to the inclusion criteria. The formalin was used to immersed all cancer specimens. And tissues were cut to 5 μm thickness and placed on glass slides before staining. Endogenous peroxidase activity was inhibited and blocked by de-paraffinizing, rehydrating, and using 5% bovine serum albumin at 37ºC for 30 min. The treated sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.

Outcome Measures

Primary Outcomes (1)

  • Original survival

    Time from the start of the study to death from any cause. For subjects who were lost to follow-up before death, the time of last follow-up was calculated as the time of death.

    Participants were followed up for 3 years, including outpatient follow-up and telephone follow-up.

Study Arms (1)

Test group-stained by FOS antibody

EXPERIMENTAL

Sixty colorectal cancer tissue sections were included. The tissue was cut to 5 μm thick and placed on a glass slide for staining. Endogenous peroxidase activity was inhibited and blocked by deparaffin, rehydration, and treatment with 5% bovine serum albumin for 30 min at 37 ° C. The treated sections were incubated with anti-FOS (promab 30360) overnight at 4 ° C and washed three times with PBS. After that, it was required to incubate with secondary anti-peroxidation sunflower for 30 min at 37 ° C. After washing three times with PBS, the images were developed in diamine benzidine and micrographs were obtained under a light microscope.

Diagnostic Test: Immunohistochemical staining with anti-FOS

Interventions

The tissue sections were incubated with anti-FOS (promab 30360) at 4ºC overnight and washed three times with PBS. After that, it is required that incubation with secondary anti-peroxidation sunflower at 37ºC for 30 minutes. After washing three times again with PBS, the sections were developed in diaminobenzidine and microscopic images were made by light microscopy.
