[The retrospective observation of the cervical smear of the cervical squamous cell cancerous patients].

This study is aimed cytologically to observe the development of the squamous cell carcinoma and to study the role of the cervical smear in the diagnosis of the cervical cancer. The cervical squamous cell cancerous patients who have the past history of the cervical smear for more than six months were selected and their cervical smears were analyzed retrospectively. The result of the cervical smear were classified into three: Negative, suspicious and positive for the statistical purposes. Each patient's cervical smears were arranged spectroscopically by the length of the elapsed time from the date of the smear to that of the diagnosis. The result of the cervical smear, the length of the elapsed time and the progression of the carcinoma were observed. It was suggested cytologically that the cervical squamous cell carcinoma will grow more slowly. This result showed us the possibility of the extension of the cytologic screening interval for the diagnosis of the cervical cancer. But the cytological analysis of the individual cervical smears suggested us that there are some problems about the confidence of the cytological diagnosis of the cervical cancer. It is our impression that the conservative screening interval will be better to keep the high diagnostic accuracy.
