ABSTRACT
OBJECTIVE:
To validate the Heidenreich criteria for patient selection for unilateral retroperitoneal lymph node dissection (RPLND) for residual masses after chemotherapy for nonseminomatous germ cell tumor (NSGCT). SUBJECTS/PATIENTS ANDMETHODS:
For validation, the data of 59 patients who underwent RPLND for residual masses of NSGCT were used. Of these patients, 23 (39 %) qualified for a modified RPLND, the others had an indication for a bilateral dissection. Results from histopathology after RPLND and follow-up data for relapse inside or outside the zone of the resection template were considered for validation.RESULTS:
In the study cohort, median age at time of RPLND was 31 years. The 2-year disease-free survival was 90 and 96 % for the bilateral and the unilateral RPLND patients, respectively. Overall, 8 (14 %) relapses were observed after a median follow-up of 54 month. Of these, 6 were outside of the resection field and 2 were in-field. Of the 23 patients with indication for a modified RPLND, 1 patient relapsed in the contralateral testis and 1 inside the modified RPLND template. No relapse was observed outside the modified RPLND field and inside the untouched contralateral RPLND field. The Heidenreich criteria did therefore not misclassify a single patient.CONCLUSION:
The Heidenreich criteria for the selection of candidates for unilateral RPLND for residual masses after chemotherapy allow a highly reliable selection of patients. The application of the Heidenreich criteria can help to reduce comorbidity and invasiveness of RPLND.
