Während Schiller bereits 1953 darauf aufmerksam machte, daß invasive Krebse gelegentlich ohne größere Epithelabnormitäten der Zervixoberfläche vorkommen können (66), führten die hohen Versagerraten der Vorsorge in neuerer Zeit zu Spekulationen über einen zweiten, aggressiv wachsenden Karzinomtyp (2, 5, 6, 7,16,21,24,38,39, 41, 57, 59, 70).

Historical data, histological parameters and follow-up findings were reviewed both in 75 "prophylaxis failures" and in 255 cases of clinical cervical carcinoma treated surgically (Wertheim's procedure); all of these cases were diagnosed between 1974 and 1980. In 29.5% of the patients preventive care or respectively gynaecological examination failed. The many and varied causes of errors are discussed. Neither the histological tumour type, nor the lymph-node metastasis rate, nor the frequency of recurrence, nor the mortality figures are indicative of a more aggressive type of tumour in the "prophylaxis failures". Mortality among the latter is 13.3%, as opposed to 15.3% in the entire patient collective, the lymph-node metastasis rate 25.3% as compared to 31.8% overall, and the recurrence rate 18.1% as compared to 18.8% overall. As expected, cases with obviously delayed diagnosis have the highest mortality rate, i.e., 25% as against 15.3% overall. There is not a single case in which cancer can be shown to have developed without a preceding precancerous stage. It is suspected that mistakes made while obtaining smears are the principal cause of failure of prophylaxis, followed by errors of evaluation, in histology, and in therapeutic measures taken after histological confirmation of cervical neoplasm. These results do not in any way exclude an aggressive type of tumour in rare individual cases; however, the occurrence of such a tumour would be an exception.

Five hundred and seventy‐two patients with uterine carcinoma, treated at the Department of Gynecology, Cancer Institute Hospital, Tokyo, were interviewed, and 200 healthy women were also interviewed as controls. The results are as follows: 1. the age at first intercourse is lower in the carcinoma group; 2. the carcinoma group showed increasing parity; 3. all the unmarried patients in the cervical carcinoma group have had sexual intercourse; 4. patients having had syphilis were more numerous in the uterine carcinoma group, and the Wasser‐mann‐positive patients were also significantly higher in this group; 5. the proportion of patients whose husbands had phimosis was higher in the cervical carcinoma group, and 6. the proportion of patients with uterine carcinoma who had mothers with uterine carcinoma was higher than the control group. It is concluded that uterine carcinoma has some genetic background and that early age at first intercourse and other cervical tissue contaminant factors are important.

The cervical cancer screening program in Taiwan was carried out in two phases. This study focused on the first 10-year screening program. Univariate descriptive analysis with chi-square test and multivariate analysis with logistic regression were applied to find the significant risk factors related to cervical cancer in Taiwan. Comparison of Phase I and II screening revealed a cohort effect. The high examination rate in women aged 30 to 39 years in Phase I resulted in a drop in the suspicious rate in the 35 to 44 year age group in Phase II, and a decreasing trend of age-specific death rates from both cervical and uterine cancer in the 40 to 49 year age group based on all of the female population in Taiwan. In Phase II, an increasing trend in ratio of carcinoma in situ to invasive carcinoma was also found. These findings suggest that the 10-year screening program in Taiwan conducted by the Cancer Society of the Republic of China has been effective. How to increase the examination rate is the key issue in the control of cervical cancer in Taiwan.
