Outcomes of post-chemotherapy robot-assisted retroperitoneal lymph node dissection in testicular cancer: multi-institutional study.

To evaluate the perioperative and oncological outcomes after post-chemotherapy robot-assisted retroperitoneal lymph node dissection (PC-RARPLND).

We retrospectively reported the perioperative and oncological outcomes of all the patients with testicular cancer who underwent PC-RARPLND at three tertiary teaching centers. Descriptive statistical measures were used to report demographic, clinical, intraoperative, postoperative and oncological outcomes.

There were 43 consecutive patients who underwent PC-RARPLND at the participating institutions. Mean patient age was 29.2 years (± 8.2), BMI was 26.6 kg/m2 (± 6.2). The mean size of retroperitoneal mass was 4.1 cm (± 3.5). Full bilateral template dissection was performed in 38 (88.3%) patients. Nerve sparing was attempted in 19 (44.1%) patients. Mean operative time was 374 min (± 132) and estimated blood loss was 292 ml (± 445.6). The mean postoperative LOS was 2.8 days (± 5.9). There was a total of 12 complications in 10 patients (Clavien grade I = 5, II = 3, III = 3 and IV = 1). Postoperative pathology demonstrated 24 patients (55%) with necrosis/fibrosis, 16 (37%) with teratoma and 3 (7%) with viable tumor. Mean lymph node (LN) yield was 26.5 LNs (SD ± 16.1). Patients were followed for a mean of 30.7 months (± 24.7). No deaths were documented during follow-up and 2 pulmonary recurrences were identified. Antegrade ejaculation was preserved in 70.6% of patient who underwent nerve sparing. Limitations included retrospective nature and limited follow up.

PC-RAPLND is safe and technically reproducible. It provides improved morbidity and less convalescence.
