Analysis of cancer registration data in Ege University: evaluation of 34134 cases

OBJECTIVES

Ege University Cancer data is being collected by Ege University Cancer Fight against Cancer, Practice and Research Center within the “İzmir Cancer Incidence and Data Collection Project” which initiated in 1991. Gender, tumor type, stage and their relationship with residence place were analyzed in 34134 cases that was diagnosed cancer and treated in our hospital between 1992-2004.

METHODS

Of the patients, 56.6% were male and 43.4% were women. Stage distribution was as following: 31.6% local, 43% local advanced and 25.4% metastatic disease.

RESULTS

It was observed that men compared to women (p=0.00), patients who live outside İzmir compared to patients living in İzmir (p=0.00) presented to the hospital with more advanced disease. When residence area, stage and gender were evaluated together, it was determined that women (p=0.011) and men (p=0.04) who were living in İzmir have been diagnosed at early stage. According to tumor groups, while patients with larynx, prostate or breast cancer who were living in İzmir has been diagnosed at early stage (p=0.05, p=0.008, p=0.000, respectively), no significant correlation could be detected among patients with lung, colorectal, cervix and endometrial cancer.

CONCLUSION

People who live in cities benefit from proximity to developed diagnose and medical centers and the effects of screening and training programmes are observed over women. Cancer training programmes should be enlarged for men besides rural areas.
