[The preliminary research of maxillary sinus cancer on oncogene level].
OBJECTIVE
To determine the oncogene c-myc, bcl-2' product expression in the maxillary sinus cancer and to investigate its clinical significance.


METHODS
In 46 maxillary sinus cancer and 56 normal nasal mucous membrane, immunochemical method was adopted to determine oncogene c-myc and bcl-2' product.


RESULTS
In the normal nasal mucous membrane, the positive rates of oncogene c-myc and bcl-2' product were 0; in the maxillary sinus cancer, the positive rates of c-myc and bcl-2' product were 73.91 (34/46), 60.87 (28/46) respectively. The positive rate of c-myc' product in the relapse group(91.67%, 11/12) was significantly higher than that in the non-relapse group(67.65%, 23/34), P < 0.01; the positive rate of bcl-2' product in the relapse group(50%, 6/12) was significantly lower than that in the non-relapse group(64.71%, 22/34), P < 0.05; the positive rate of c-myc' product in the stage IV (88.89%, 8/9) was significantly higher than that in the stage II (63.64%, 7/11), P < 0.05; the positive rate of bcl-2' product in the stage II (72.73%, 8/11) was significantly higher than that in the stage IV (55.56%, 5/9), P < 0.05; the positive rate of bcl-2' product was in the negative correlation to the pathological grade of primary carcinoma.


CONCLUSIONS
The oncogene c-myc and bcl-2 take part in the genesis and advancing course of maxillary sinus cancer. Their products were the important oncogology indexes, which might be useful to determine illness condition and predict relapse.
