A case of synchronous advanced gastric cancer and locally advanced prostate cancer with combined laparoscopic and robotic surgery: A case report.

INTRODUCTION

The optimal management strategy for synchronous gastric cancer (GC) and prostate cancer (PCa) remains unclear, particularly in cases in which two cancers are progressive.

PRESENTATION OF CASE

A 68-year-old man diagnosed with synchronous advanced GC and locally advanced PCa was referred to our institution. Laparoscopic total gastrectomy (LTG) and robotic-assisted radical prostatectomy were simultaneously performed. The postoperative course was similar to the standard postoperative course of LTG alone. Pathological diagnoses were T3N3aM0 gastric adenocarcinoma and T3N0M0 prostatic adenocarcinoma. Adjuvant chemotherapy and adjuvant androgen deprivation therapy (ADT) for GC and PCa were initiated on postoperative days 15 and 27, respectively. Six months subsequent to surgery, the patient received adjuvant chemotherapy and ADT, and no evidence of cancer recurrence was observed.

DISCUSSION

In terms of survival, curative resection with adjuvant therapy is advantageous for patients with advanced GC or locally advanced PCa. At present, treatment for synchronous cancer should be combined with optimal management for individual cancers. Minimally invasive surgery may play an important role in the multidisciplinary treatment of synchronous advanced cancer.

CONCLUSION

Combined laparoscopic and robotic surgery for synchronous GC and PCa allows for minimally invasive radical resection and appropriate adjuvant therapy.
