          Abstract

          Background

          Renal cell carcinoma is well-known for its propensity to metastasize to unusual sites. However, metastasis to the gallbladder has been rarely reported in the literature.

          Case presentation

          A 75-year-old Japanese (Asian) woman presented for further evaluation of a gallbladder polyp, 15 years after right radical nephrectomy for renal cell carcinoma. Computed tomography revealed a 12 mm enhancing pedunculated tumor in the gallbladder fundus. Open simple cholecystectomy was performed and the tumor was histologically confirmed as a metastasis of renal cell carcinoma to the gallbladder. Our patient is alive and has been disease-free for 3 years after cholecystectomy.

          Conclusions

          Although metastasis of renal cell carcinoma is a rare differential diagnosis of gallbladder tumors, simple cholecystectomy is likely to offer a chance of long-term survival for patients with gallbladder metastases of renal cell carcinoma.

          Resection of metastatic renal cell carcinoma.

          Resection of solitary metastases from renal cell carcinoma (RCC) is associated with a 5-year survival rate of 35% to 50%. Selection criteria are not well defined. We retrospectively analyzed our experience with 278 patients with recurrent RCC from 1980 to 1993. One hundred forty-one of 278 patients underwent a curative metastectomy for their first recurrence (44% 5-year overall survival [OS] rate), 70 patients underwent noncurative surgery (14% 5-year OS rate), and 67 patients were treated nonsurgically (11% 5-year OS rate). Favorable features for survival were a disease-free interval (DFI) greater than 12 months versus 12 months or less (55% v 9% 5-year OS rate; P < .0001), solitary versus multiple sites of metastases (54% v 29% 5-year OS rate; P < .001), and age younger than 60 years (49% v 35% 5-year OS rate; P < .05). Among 94 patients with a solitary metastasis, lung (n = 50; 54% 5-year OS rate) was more favorable than brain (n = 11; 18% 5-year OS rate; P < .05). Survival rates after curative resection of second and third metastases were not different compared with initial metastectomy (46% and 44%, respectively, v 43% 5-year OS rates; P = nonsignificant). Favorable predictors of survival by multivariate analysis included a single site of first recurrence, curative resection of first metastasis, a long DFI, a solitary site of first metastasis, and a metachronous presentation with recurrence. Selected patients with recurrent RCC who can undergo a curative resection of their disease have a good opportunity for long-term survival, particularly those with a single site of recurrence and/or a long DFI.

            Kidney cancer.

            In the USA, the incidence of kidney cancer has increased 43% since 1973. The risk of the disorder is higher in men than in women and increases with age. The von Hippel-Lindau tumour-suppressor gene is inactivated in over 75% of sporadic cases. Metastatic disease is present in 20-30% of patients at diagnosis. Early-stage kidney cancer is treated with a radical nephrectomy, but under certain circumstances a partial nephrectomy may be done. Tumour thrombus into the vena cava or right atrium requires thoracotomy and hypothermic circulatory arrest for successful removal of the tumour, but should not be done if extensive nodal or frank metastatic disease is present. Interleukin-2 is the systemic therapy of choice for metastatic disease at present, with long-term relapse-free survival of 5-8%. Several treatments including anti-angiogenesis drugs, cyclin-dependent kinase inhibitors, and differentiating agents are being actively investigated. Fluorouracil has a 10-15% response rate, and surgical excision of isolated metastases should always be considered. Therapy for metastatic renal cancer remains inadequate, but recent developments in basic and clinical research suggest future improvement.

              Renal cell carcinoma with metastases to the gallbladder: four cases from the National Cancer Institute (NCI) and review of the literature.

              We evaluate presentation and outcome of patients with metastatic RCC to the gallbladder from our institution and published literature. Patients with a history of gallbladder metastasis from RCC were selected from our institution's prospective database. A systematic PubMed search was performed to identify articles describing patients with metastatic RCC to the gallbladder. The final cohort included 33 patients: 4 from our institution and 29 from 28 previously published cases. Survival analysis was conducted using log-rank Kaplan-Meier analysis. Median patient age was 63 years and the majority of patients were male. Most patients were asymptomatic and diagnosed with gallbladder metastasis on imaging performed for surveillance or staging. The median time to gallbladder metastasis following nephrectomy was 4 years. Metastasis to the gallbladder occurred both synchronously (33%) and metachronously (67%). Of the patients with available histology, all had clear cell RCC (n = 28). Of all patients, 13 (39%) had metastasis only to the gallbladder, while 20 (61%) had additional sites of metastasis. The most common sites of additional metastasis were contralateral kidney (30%), pancreas (21%), lung (18%), adrenal (18%), and lymph nodes (9%). All patients underwent cholecystectomy. At a median follow up time of 1.5 years after cholecystectomy, 54% of patients had no evidence of disease, 14% were alive with metastasis, 23% had died from metastatic RCC, and 9% died from causes unrelated to their cancer. Gallbladder metastasis from RCC is a rare event that may occur synchronously or metachronously with most patients being asymptomatic. Clear cell carcinoma appears to be the primary pathology associated with gallbladder metastasis. High rates of bilateral RCC and pancreatic metastasis suggest novel associations in patients with RCC and gallbladder metastasis. Published by Elsevier Inc.
