Long-term retroperitoneal lymph node dissection outcomes for nonseminomatous germ cell tumors with postchemotherapy retroperitoneal residual tumors, in a specialized hospital of Saudi Arabia.

BACKGROUND: In men under the age of 35 years, testicular cancer is the most prevalent solid tumor. Additional treatment is necessary for many people with nonseminomatus germ cell tumors (NSGCTs). Whether in conjunction with chemotherapy or as a stand-alone procedure, retroperitoneal lymph node dissection (RPLND) continues to play a critical role in the treatment of these patients. There is a lack of information in Saudi Arabian literature about the long-term oncologic outcome of NSGCT following RPLND surgery.

OBJECTIVE: The study's goals were to identify clinical and pathological characteristics related with long-term survival following NSGCT for RPLND, as well as to assess the surgical and oncological results of this treatment.

METHODOLOGY: From January 2010 to April 2021, nine adults who had had orchidectomy for testicular cancer and RPLND following treatment for the evidence of persistent NSGCT disease at our hospital were included in this retrospective research. Demographic information, laboratory results, radiological findings, staging, chemotherapy and radiotherapy status, surgical procedure details, perioperative problems, morbidity, and mortality were all acquired from patients' medical records. Rates of disease return and overall survival. SPSS was utilized for the data analysis.

RESULTS: During the study period, nine patients with NSGCT underwent RPLND, with a mean age of 28 years (5.4: standard deviation). The most common diseases were yolk sac and embryonal cell cancer. In addition to receiving neoadjuvant chemotherapy, all patients had a Clavien-Dindo score of 2, and there was no mortality after RPLND. Overall median survival time was 26, and disease-free survival time was 21 months. Overall survival at 1 year was 86%, and at 5 years, it was 66%. The prognosis of embryonal cell cancer was more optimistic than that of a tumor of the yolk sac.

CONCLUSION: We have shown that RPLND has an extremely low rate of morbidity and postoperative problems. In terms of oncology, it results in adequate overall and disease-free survival rates, with low morbidity and postoperative complications.
