NCT ID: NCT00656955

Last Updated: 2020-06-18

Basic Information

• Recruitment Status: COMPLETED
• Total Enrollment: 1002 participants
• Study Classification: OBSERVATIONAL
• Study Start Date: 2008-04-17
• Study Completion Date: 2020-06-17

Brief Summary

Background:

In Central Europe, mortality rates for kidney cancers are higher and survival rates are lower than in the United States and Western Europe overall.

The Central and Eastern European Renal Cancer Case-Control Study (CEERCC), completed in 2002, offers an opportunity to identify determinants that predict 5-year survival among kidney cancer patients.

Objectives:

To assess disease recurrence and progression among former participants in the CEERCC.

To investigate the effect of genetics, lifestyle factors, medical conditions, occupation and diet on the outcome of kidney cancer patients in Europe.

Eligibility:

Former participants or next-of-kin of former participants in the CEERCC study.

Design:

Participants or their next-of-kin are interviewed for 60 minutes and are requested permission to collect relevant information from their or their family member s hospital and cancer registry records.

Detailed Description

Previously we proposed to conduct a follow-up study of kidney cancer in the high risk region of Central and Eastern Europe. This study was conducted through the follow-up of a group of patients with kidney cancer, that were previously enrolled in the study entitled, Occupation, Genetic Susceptibility Kidney Cancer: Central European Case-Controls Study, PI Dr. Wong-Ho Chow, OEEB, DCEG, NCI, protocol No 01-C-NO63, a study for which field work and data analyses of the case control study were completed. We had originally planned to conduct the follow-up study in seven centers in four countries, including Romania, Poland, Russia, and the Czech Republic. In each center, cancer-related information was to be extracted from vital statistics, cancer registry, and/or medical records. For deceased patients, next-of-kin were to be interviewed using a brief questionnaire.

A pilot study was conducted to determine the feasibility of collecting survival information including 5-year survival status, date of death, cause of death, and date of last follow-up if alive from 220 cases across the seven collaborating centers. The feasibility of extracting additional data including surgical and medical treatment procedures used to treat primary disease, the recurrence and progression of primary disease was also determined. However, based on results obtained from the pilot study, we determined that it is feasible to collect follow-up data from kidney cancer cases from four centers in the Czech Republic and one center in both Poland and Russia.

Medical records/archives for Romanian cases were located in hospitals that were completely destroyed during reconstruction therefore, it was impossible to collect any information from this subset of patients. Exclusion of these records will not affect study power since most of the cases were from the Czech Republic. The objective of our proposed study remains the same:( 1) to assess the 5-year survival status of kidney cancer patients in the Central and Easter European Renal Cell Carcinoma Study; (2) to examine prevalence of recurrent disease and progression; (3) to investigate additional patient-tumor-and genetic determinant of 5-year survival in cases.

Eligibility Criteria

Inclusion Criteria

To be eligible for this study, patients needed to have participated as a histologically confirmed renal cancer case in the previous case-control study entitled Central European Renal Cancer Case-Control (CEERCC) Study which was completed in 2002.

Exclusion Criteria

Children less than 18 are not eligible to participate in this study because there were no kidney cancer cases observed in the CEERCC Study that were less than 18 years of age.
