Diagnostic Yield of Colonoscopy Surveillance in Testicular Cancer Survivors Treated With Platinum-based Chemotherapy (CATCHER)

January 27, 2023 updated by: The Netherlands Cancer Institute

Testicular cancer (TC) survivors treated with platinum-based chemotherapy have an increased risk of colorectal cancer (CRC) (hazard ratio (HR) 3.9 for platinum-containing chemotherapy versus no platinum-containing chemotherapy, 95% confidence interval 1.7-8.9). Colonoscopy screening can reduce CRC incidence and mortality. Given this increased risk of CRC, colonoscopy surveillance should be considered for TC survivors treated with platinum-based chemotherapy.

The aim of this study is to evaluate the diagnostic yield of advanced colorectal neoplasia during colonoscopy surveillance in TC survivors treated with platinum-based chemotherapy. The secondary objectives are to determine cost-effectiveness and burden of colonoscopy. Furthermore, the molecular profile of advanced neoplasia will be evaluated to create insight into the carcinogenesis. The effectiveness of fecal immunochemical testing (FIT) will be evaluated with colonoscopy as a reference. Finally, blood plasma platinum-levels will be determined to examine a potential correlation with the outcome of the ccolonoscopy.

Detailed Description

Rationale: Testicular cancer (TC) survivors have an increased risk of various second primary malignancies. A recent cohort study showed that platinum-based chemotherapy was associated with increased risk of colorectal cancer (CRC) in a dose dependent manner (hazard ratio (HR) 3.9 for platinum-containing chemotherapy versus no platinum-containing chemotherapy, 95% confidence interval 1.7-8.9). Colonoscopy screening can reduce CRC incidence and mortality. Given this increased risk of CRC, colonoscopy surveillance should be considered for TC survivors treated with platinum-based chemotherapy. However, the diagnostic yield, cost-effectiveness and burden of colonoscopy in TC survivors treated with platinum-based chemotherapy has never been assessed. Additionally, the molecular profile of advanced neoplastic lesions and CRC in TC survivors treated with platinum-based chemotherapy has not been established but can provide valuable insight into CRC carcinogenesis in this group of patients. Also the effectiveness of fecal tests has not been evaluated among TC survivors treated with platinum-based chemotherapy compared to that among population controls.

Objective: The primary objective of this study is to assess the diagnostic yield of colonoscopy surveillance in TC survivors treated with platinum-based chemotherapy. The secondary objectives are 1) to evaluate the molecular characteristics of colorectal (advanced) neoplasia in TC patients in relation to the cumulative doses of/ level of plasma cisplatin, in order to improve the understanding of CRC carcinogenesis following cisplatin exposure, 2) to determine the association of platinum levels in plasma with cumulative administered cisplatin doses as well as with presence of colorectal (advanced) neoplasia at colonoscopy and to determine the platinum amount in the colorectal tissue derived during primary colonoscopy screening, 3) to evaluate the cost-effectiveness and burden of colonoscopy. Our 4th secondary objective is to assess the effectiveness of a stool test for CRC screening in TC survivors compared to standard colonoscopy.

Study design: A multicentre prospective cross-sectional screening study.

Study population: TC survivors will be derived from an established, well-defined multicentre cohort. Inclusion criteria of this study are 1) participants should have been treated for TC in a participating Dutch hospital before the age of 50 years, 2) treatment consisted of at least three cycles of platinum-based chemotherapy (cisplatin) with or without additional radiotherapy, 3) participants should be at least 8 years after start of treatment, with a minimum age at first colonoscopy screening of 35 years, 4) the maximum age at participation is 75 years, 5) detection and potential treatment of advanced colorectal neoplasia is considered beneficial.

Quality of life before and after colonoscopy will be evaluated by validated questionnaires (EQ-5D). This is a standardized instrument to evaluate five health categories (mobility, self care, daily activities, pain/discomfort and fear/depression). The items can be scored in three values; no/some/a lot of problems. A higher score represents a worse outcome.

Furthermore, the health will be scored on a 0 to 100 scale. A higher score will correspond with a better health interpreted health of the participant.
