Hysterectomy-corrected incidence and mortality rates of cervical cancer in Germany

Incidence and mortality rates of cervical cancer (C53 by ICD-10) have to be corrected significantly upwards after excluding the women from the reference population whose uterus was removed surgically. The current study is based on the German Health Interview and Examination Survey for Adults (DEGS1) according to which the prevalence of hysterectomy in Germany in 2011 among women aged over 18 years was 17.4%. As per age pattern of this prevalence the incidence and mortality rates of cervical cancer are corrected. Maximal corrections can be found for women of 70-79 years. In this age group the incidence rate is corrected from 13.6 to 22.5 by 65.4%, the mortality rate from 7.5 to 12.4 by 65.3%.Inzidenz und Mortalität von Gebärmutterhalskrebs (C53 nach ICD-10) müssen signifikant nach oben korrigiert werden, wenn aus der betrachteten Referenzbevölkerung die Frauen ausgeschlossen werden, deren Gebärmutter operativ entfernt wurde. Diese Arbeit stützt sich auf die Studie zur Gesundheit Erwachsener in Deutschland (DEGS1), nach der die Hysterektomie-Prävalenz in Deutschland 2011 bei über 18-jährigen Frauen bei 17,4% lag. Auf Grundlage der Altersverteilung dieser Prävalenz werden die Inzidenz- und Mortalitätsraten von Gebärmutterhalskrebs entsprechend korrigiert. Maximale Korrekturen resultieren bei 70-79-jährigen Frauen mit einer Inzidenzkorrektur von 13,6 auf 22,5, d.h. um 65,4% und einer Mortalitätskorrektur von 7,5 auf 12,4, d.h. um 65,3%. Die mögliche Prävention durch eine HPV-Impfung gewinnt damit an Relevanz

Are Colon and Rectal Cancer Two Different Tumor Entities? A Proposal to Abandon the Term Colorectal Cancer

Colon cancer (CC) and rectal cancer (RC) are synonymously called colorectal cancer (CRC). Based on our experience in basic and clinical research as well as routine work in the field, the term CRC should be abandoned. We analyzed the available data from the literature and results from our multicenter Research Group Oncology of Gastrointestinal Tumors termed FOGT to confirm or reject this hypothesis. Anatomically, the risk of developing RC is four times higher than CC, while physical activity helps to prevent CC but not RC. Obvious differences exist in molecular carcinogenesis, pathology, surgical topography and procedures, and multimodal treatment. Therefore, we conclude that CC is not the same as RC. The term “CRC” should no longer be used as a single entity in basic and clinical research as well as other areas of classification
