Port site recurrence after laparoscopic radical nephrectomy: a case report

Abstract

BackgroundDue to the recent development of laparoscopic devices, laparoscopic radical nephrectomy is the standard procedure for localized renal cell carcinoma. However, some studies have reported postoperative port site metastasis in several cancers.Case presentationA 68-year-old Asian-Japanese man was referred to our hospital for a further examination of his right renal tumor in 2009. Due to a clinical suspicion of renal cell carcinoma, laparoscopic nephrectomy was performed. The histopathological diagnosis was clear cell renal cell carcinoma. Follow-up computed tomography revealed a mass between the internal oblique muscle of his abdomen and the transverse muscle of his abdomen in 2014. The tumor size gradually increased, and positron emission tomography-computed tomography revealed the accumulation of fludeoxyglucose in that tumor with maximum standardized uptake value of 2.7. Based on these findings, port site recurrence was suspected, and tumor resection was performed in 2017. The pathological diagnosis was metastatic clear cell renal cell carcinoma.ConclusionsHere we report a rare case of port site metastasis that was successfully treated 7 years after laparoscopic nephrectomy.

Inflammatory Pseudotumor Formation at a Port Site after Robotic Partial Nephrectomy for Renal Cell Carcinoma

“…In comparison, the risk of PSM might have been lower in the present case. However, Shimokihara et al [10] reported a case of PSM with an initially low-risk RCC similar to the present case. Therefore, we suggest that any tumor suspicious for PSM should be resected.…”

“…The preoperative differentiation between IPT and PSM of RCC is difficult because of the rarity of both conditions, which were reported in very few case reports [2][3][4][9][10][11]. Based on the limited information, both IPT and PSM of RCC are usually asymptomatic while retaining a small tumor burden.…”

“…The diagnosis depends primarily on imaging studies; however, there are no distinguishable radiologic features of IPT, which vary according to the histological content and location [1]. Additionally, FDG-PET appears to be impractical as both conditions can display positive FDG-PET uptake [4,5,10].…”

Comparison of Cancer Specific Outcomes following Minimally Invasive and Open Surgical Resection of Early Stage Kidney Cancer from a National Cancer Registry

“…13 This report and a simultaneous study using a national database, 10 has led to modification of national guidelines to caution against MIS for cervical cancer and to cessation of MIS cervical cancer surgery at some institutions. 14 Oncologic concerns for one type of cancer may not translate across all types, however, among patients with kidney cancer, there are published reports of atypical recurrences following MIS [15][16][17] and we have noticed these in our practice as well. Thus, there is a need to better understand this scope of this issue across a broader population.…”

Retrovesikales Rezidiv eines Nierenzellkarzinoms 14 Jahre nach laparoskopischer Nephrektomie. Ein Fallbericht

“…Nguyen et al verglichen die Rezidivraten des Harnblasenkarzinoms nach offenen und roboterassistierten radikalen Zystektomien, wobei eine höhere Inzidenz einer Peritonealkarzinose bei roboterassistierten Zystektomien (21 %) im Vergleich zu offenen Zystektomien (8 %) beschrieben wurde 9 . Bezüglich des Nierenzellkarzinoms sind nach laparoskopische Tumornephrektomie 17 Fälle mit Port-site Metastasen in der Literatur beschrieben 10 11 .…”
