Impact of perineal pseudocontinent colostomy on perineal wound healing after abdominoperineal resection.

BACKGROUND: Abdominoperineal resections (APR) for anorectal tumors are associated with a high rate of perineal wound complications. The aim of this study was to evaluate the impact of pseudocontinent perineal colostomy (PPC) following APR on perineal wound healing. METHODS: All patients undergoing APR between 2000 and 2009 were retrospectively reviewed. Perineal wound healing was compared between patients with PPC and those with perineal closure alone. RESULTS: APR was performed in 132 patients, including 31 with PPC and 101 with no PPC. Risk factors such as radiotherapy, smoking, diabetes mellitus, and obesity were not different between the two groups. The PPC group had significantly fewer cases of omentoplasty and adenocarcinoma histology. The overall perineal complication rate, perineal infection, or wound dehiscence was similar in the two groups, but the perineal healing rate at 6 and 12 weeks was significantly increased in the PPC group than in the non-PPC group (70.9% vs. 50%, P = 0.04, at 6 weeks; 90.3% vs. 73%, P = 0.04, at 12 weeks). CONCLUSIONS: PPC accelerates perineal wound healing after APR without decreasing the overall perineal complication rate.

Real-time full field laser Doppler imaging.

We present a full field laser Doppler imaging instrument, which enables real-time in vivo assessment of blood flow in dermal tissue and skin. This instrument monitors the blood perfusion in an area of about 50 cm(2) with 480 × 480 pixels per frame at a rate of 12-14 frames per second. Smaller frames can be monitored at much higher frame rates. We recorded the microcirculation in healthy skin before, during and after arterial occlusion. In initial clinical case studies, we imaged the microcirculation in burned skin and monitored the recovery of blood flow in a skin flap during reconstructive surgery indicating the high potential of LDI for clinical applications. Small animal imaging in mouse ears clearly revealed the network of blood vessels and the corresponding blood perfusion.

Perioperative chemotherapy compared with surgery alone for resectable gastroesophageal adenocarcinoma: an FNCLCC and FFCD multicenter phase III trial.

PURPOSE: After curative resection, the prognosis of gastroesophageal adenocarcinoma is poor. This phase III trial was designed to evaluate the benefit in overall survival (OS) of perioperative fluorouracil plus cisplatin in resectable gastroesophageal adenocarcinoma. PATIENTS AND METHODS: Overall, 224 patients with resectable adenocarcinoma of the lower esophagus, gastroesophageal junction (GEJ), or stomach were randomly assigned to either perioperative chemotherapy and surgery (CS group; n = 113) or surgery alone (S group; n = 111). Chemotherapy consisted of two or three preoperative cycles of intravenous cisplatin (100 mg/m(2)) on day 1, and a continuous intravenous infusion of fluorouracil (800 mg/m(2)/d) for 5 consecutive days (days 1 to 5) every 28 days and three or four postoperative cycles of the same regimen. The primary end point was OS. RESULTS: Compared with the S group, the CS group had a better OS (5-year rate 38% v 24%; hazard ratio [HR] for death: 0.69; 95% CI, 0.50 to 0.95; P = .02); and a better disease-free survival (5-year rate: 34% v 19%; HR, 0.65; 95% CI, 0.48 to 0.89; P = .003). In the multivariable analysis, the favorable prognostic factors for survival were perioperative chemotherapy (P = .01) and stomach tumor localization (P < .01). Perioperative chemotherapy significantly improved the curative resection rate (84% v 73%; P = .04). Grade 3 to 4 toxicity occurred in 38% of CS patients (mainly neutropenia) but postoperative morbidity was similar in the two groups. CONCLUSION: In patients with resectable adenocarcinoma of the lower esophagus, GEJ, or stomach, perioperative chemotherapy using fluorouracil plus cisplatin significantly increased the curative resection rate, disease-free survival, and OS.

Oncologic and functional results after abdominoperineal resection plus pseudocontinent perineal colostomy for epidermoid carcinoma of the anus.

PURPOSE: Surgical treatment for epidermoid carcinoma of the anus is reserved for patients after failure of primary chemoradiotherapy and consists of abdominoperineal resection with permanent iliac colostomy. The purpose of this study was to analyze the oncologic and the functional outcomes after abdominoperineal resection and pseudocontinent perineal colostomy for epidermoid carcinoma of the anus after external radiation at maximal doses (60 Gy). METHODS: Between 1990 and 2006, 95 patients underwent abdominoperineal resection for an epidermoid carcinoma of the anus. Eighteen (19 percent) underwent construction of a pseudocontinent perineal colostomy. Functional results were evaluated prospectively at regular intervals. RESULTS: Complete resection (R0) was obtained in 17 of 18 patients. After a median follow-up of 33 (range, 12-198) months, 15 of 18 patients were alive, and 11 were disease free. Five-year overall and disease-free survival rates were 67 and 53 percent, respectively. Functional outcomes were available for 16 patients. According to the Kirwan score, 15 were continent, and 13 did not require pad protection. Overall, 15 of 16 patients were satisfied. CONCLUSION: Pelvic reconstruction with a pseudocontinent perineal colostomy does not compromise the beneficial effect of salvage surgery, seems to be safe and feasible even after a high dose of radiotherapy, and provides a high degree of satisfaction.

Immune modulation and microchimerism after unmodified versus leukoreduced allogeneic red blood cell transfusion in cancer patients: results of a randomized study.

BACKGROUND: Transfusion of red blood cells (RBCs) has been associated with immunomodulatory effects. Persistence of donor cells in the recipient may be contributive. STUDY DESIGN AND METHODS: A randomized single-center trial was conducted to compare microchimerism and immune responses in 35 patients undergoing cancer surgery and transfused perioperatively with either unmodified RBCs (UN-RBCs, n = 18) or leukoreduced RBCs (LR-RBCs, n = 17). Biologic parameters included microchimerism assessment peripheral blood mononuclear cell (PBMNC) phenotyping, cytokine production by stimulated PBMNCs, FoxP3 gene expression, and T-cell repertoire (TCR) analysis. RESULTS: Microchimerism was documented in 8 of 18 patients after UN-RBC transfusion while absent after LR-RBC transfusion (0/17; p = 0.001). After UN-RBC transfusion, microchimerism was associated with increased interleukin (IL)-10 production (p = 0.02), reduced TCR alteration (p = 0.04), and reduced CD56+ cell counts (p = 0.02) when compared to recipients without evidence for microchimerism. FoxP3 gene expression did not differ significantly between both treatment groups nor with the presence or absence of microchimerism in the UN-RBC group. Finally, after an initial early decrease after surgery and transfusion, IL-12 production increased and more significantly so after UN-RBC transfusion versus LR-RBC transfusion (p = 0.05). CONCLUSION: UN-RBC-induced microchimerism is associated with specific immunomodulatory effects in cancer patients who received transfusions during surgery.

Sentinel lymph nodes of colorectal carcinoma: reappraisal of 123 cases.

AIMS: Results concerning the usefulness of the sentinel lymph node (SLN) in colorectal carcinoma have been discordant. The SLN technique may be used to guide surgical resection (lymph mapping), restrict the lymph node analysis solely to the SLN (accuracy) and upgrade tumor staging when micrometastases are specifically detected in the SLN. METHODS: The blue dye injection technique was used. Serial sections of the SLNs were analyzed after hematoxylin-eosin (HES) staining. RESULTS: The SLN technique was tested in 123 patients, successfully in 112/118 (feasibility 95%) (five intraoperative exclusions). On average, twenty lymph nodes (range: 5-74) and two SLNs (range: 1-5) were identified. Lymph mapping was used in 11% of patients to guide surgical resection; the SLN was negative in 14 of 36 N+ patients (39% false-negatives); HES staining enabled detection of micrometastases in 8 of 84 initially N0 patients (10% secondary upgrading to N+). CONCLUSION: Limiting node analysis to the SLN cannot replace a complete pathology examination of all resected lymph nodes. Careful examination of serial sections of the SLN can however affect therapeutic decision making since staging may be upgraded in up to 10% of initially N0 patients.

Combination chemotherapy in advanced small bowel adenocarcinoma.

OBJECTIVE: To assess the efficacy of 5-fluorouracil (5-FU) and either platinum compounds or irinotecan in patients with advanced small bowel adenocarcinoma (SBA), for whom data on the efficacy of chemotherapy are scarce. METHODS: We reviewed data on all patients with advanced SBA who received chemotherapy over a 9-year period at our institution. RESULTS: Twenty patients with advanced SBA received a median of 6 cycles (range 2-15) of chemotherapy with 5-FU and either cisplatin (n=15), carboplatin (n=2), or oxaliplatin (n=3). The overall response rate was 21%, and median progression-free and overall survival 8 and 14 months, respectively. Toxicity was moderate. Second-line chemotherapy with 5-FU and irinotecan resulted in disease stabilization in 4 (50%) of 8 patients (median progression-free survival: 5 months), and in a biological complete response in another patient with non-measurable peritoneal carcinomatosis, allowing surgical cytoreduction surgery and hyperthermic intraperitoneal chemotherapy. No tumor response or disease stabilization was seen among the patients who received protracted venous infusion of 5-FU (n=4) or infusional 5-FU and cisplatin (n=1) as second-line chemotherapy. CONCLUSION: Chemotherapy with 5-FU and platinum compounds seems effective and well-tolerated in patients with advanced SBA. 5-FU-irinotecan combination chemotherapy deserves further investigation in the first-line setting.

Quality of life of patients operated on for low rectal cancer: impact of the type of surgery and patients' characteristics.

PURPOSE: This study was designed to compare the impact of a permanent colostomy and sociodemographic characteristics on the quality of life of patients operated on for low rectal cancer. METHODS: A cross-sectional study was performed by use of the European Organization for Research and Treatment of Cancer QLQ-C30 and CR-38 questionnaires. Patients came to the hospital to fill out the self-administered questionnaire or were sent the questionnaire by mail, followed by a live or telephone interview. All patients had undergone one of four operations: low anterior resection with colorectal or coloanal anastomosis (non-stoma group), or abdominoperineal resection with pseudocontinent perineal colostomy (nonstoma group) or left lower quadrant colostomy (stoma group). RESULTS: A total of 132 patients were included for analysis and there were no missing data. For the majority of quality of life scores (26/29), there was no significant difference between stoma and nonstoma patients. However, stoma patients complained of diminished body image (P = 0.0022), and this was especially true for married (P = 0.0073) and less educated (P = 0.0014) patients at subgroup analysis. Stoma patients experienced greater financial worries (P = 0.0029), whereas nonstoma patients had greater gastrointestinal concerns (P = 0.0098). CONCLUSIONS: Although most quality of life scores between stoma and nonstoma patients were similar, significant differences regarding body image, finance, and gastrointestinal symptoms, especially for married and less educated patients, were noticed. These factors should be taken into account, along with oncologic criteria, to better tailor treatments to patients.

Hepatic and extrahepatic colorectal metastases: when resectable, their localization does not matter, but their total number has a prognostic effect.

BACKGROUND: The presence of extrahepatic disease (EHD) is considered a contraindication to hepatectomy in patients with colorectal liver metastases. After resection, the prognosis is based more on the total number of resected metastases (located inside and outside the liver) than on the site of these metastases (only inside the liver or not). METHODS: A total of 308 patients with colorectal cancer underwent hepatectomy, and 84 (27%) also underwent resection of miscellaneous EHD. The study was a prospective data registration and retrospective analysis. When considering the total number of resected metastases, each liver metastasis and each EHD location was counted as one lesion. Univariate and multivariate analyses were performed. RESULTS: The median follow-up was 99 months. The overall 5-year survival rate was 32%. In the multivariate analysis, the total number of metastases (inside or outside the liver) had a greater prognostic value than the criterion "presence or absence of EHD." Considering the total number of resected metastases (whatever their site), 5-year survival rates were 38% (SD: 4%) in the group with one to three metastases, 29% (SD: 5%) in patients with four to six metastases, and 18% (SD: 5%) in patients with more than six metastases (P = .002). A very simple prognostic score based on sex and the total number of metastases is proposed. CONCLUSIONS: EHD, when resectable, is no longer a contraindication to hepatectomy. More importantly, the total number of the metastases, whatever their location, has a stronger prognostic effect than the site of these metastases.

Ex vivo sentinel lymph node study for rectal adenocarcinoma: preliminary study.

Intraoperative sentinel lymph node (SLN) detection has been reported for colon cancer, but no study has focused on rectal cancer. Only an ex vivo technique can be performed easily in this location. We evaluated SLN detection using blue dye injection in patients with rectal adenocarcinoma. This prospective study included 31 patients. Preoperative radiotherapy (45 Gy) was done in 15 cases. After proctectomy the surgical specimen was examined in the operating room. Submucosal peritumoral injections were done. One to three SLNs were retrieved. The SLNs were sectioned at three levels and examined histologically and then, if negative by hematoxylin-eosin (H&E) staining and immunohistochemistry (IHC). There were 7 abdominoperineal resections, 12 colorectal anastomoses, 11 coloanal anastomoses, and 1 Hartmann procedure. The median number of lymph nodes harvested was 21 (7-38). A SLN was identified in 30 cases (feasibility 97%). The mean number of SLNs was 2 (0-3). A micrometastasis was discovered in 3 of 23 pNO cases when H&E was used on multisection levels, thus changing the stage to pN1. Each time the only positive lymph node was the SLN. IHC evaluation did not change the result, as only isolated tumor cells were discovered in one case. Only four of seven N+ patients had a positive SLN, resulting in a false-negative rate of 43%. Ex vivo detection of SLNs is possible for rectal cancer and is a simple technique. Classic analysis using H&E remains the gold standard. However, SLNs detection can change the tumor stage by upstaging nearly 15% of the tumors from T2-3N0 to T2-3 N+.

Inguinal canal as an anatomic sanctuary site of relapse in peritoneal carcinomatosis previously treated with intraperitoneal chemotherapy.

Early postoperative intraperitoneal chemotherapy (EPIC) and intraoperative peritoneal hypertermic chemotherapy (IPHC) are used in addition with cytoreductive surgery to treat with curative intent peritoneal carcinomatosis arising from colorectal adenocarcinomas. Three patients with such a disease were treated with perioperative intraperitoneal chemotherapy in addition to cytoreductive surgery and presented isolated local recurrence located in the inguinal canal (round ligament in two and spermatic cord in one). All these patients were treated by local surgical excision. No patient showed evidence of intra-abdominal recurrence at the last follow-up, but one developed pulmonary metastasis. When communicating with the peritoneal cavity, the inguinal canal may act as a sanctuary site for peritoneal carcinomatosis, since it is not totally soaked by the intraperitoneal chemotherapy solution. A local recurrence is thus possible. New clinical presentations such as this one have first to be described in order to improve patient follow-up.

Hepatic arterial oxaliplatin infusion plus intravenous chemotherapy in colorectal cancer with inoperable hepatic metastases: a trial of the gastrointestinal group of the Federation Nationale des Centres de Lutte Contre le Cancer.

PURPOSE: Isolated hepatic metastases of colorectal cancer constitute a frequent and serious therapeutic problem that has led to the evaluation of hepatic arterial infusion (HAI) of different drugs. Oxaliplatin combined with fluorouracil (FU) and leucovorin is effective in the treatment of colorectal cancer. In this context, a phase II study was conducted to evaluate concomitant administration of oxaliplatin by HAI and intravenous (IV) FU plus leucovorin according to the LV5FU2 protocol (leucovorin 200 mg/m(2), FU 400 mg/m(2) IV bolus, FU 600 mg/m(2) 22-hour continuous infusion on days 1 and 2 every 2 weeks). PATIENTS AND METHODS: Patients had metastatic colorectal cancer that was restricted to the liver and inoperable. The patients were not to have previously received oxaliplatin. After surgical insertion of a catheter in the hepatic artery, patients were treated with oxaliplatin 100 mg/m(2) HAI combined with FU + leucovorin IV according to the LV5FU2 protocol. Treatment was continued until disease progression or toxicity. Response was evaluated every 2 months. RESULTS: Twenty-eight patients were included, and 26 patients were treated. Two hundred courses of therapy were administered, and the median number of courses received was eight courses (range, zero to 20 courses). The most frequent toxicity consisted of neutropenia. The main toxicity related to HAI was pain. The intent-to-treat objective response rate was 64% (95% CI, 44% to 81%; 18 of 28 patients). With a median follow-up of 23 months, the median overall and disease-free survival times were 27 and 27 months, respectively. CONCLUSION: The combination of oxaliplatin HAI and FU + leucovorin according to the LV5FU2 protocol is feasible and effective in patients presenting with isolated hepatic metastases of colorectal cancer.

Adjuvant regional chemotherapy and systemic chemotherapy versus systemic chemotherapy alone in patients with stage II-III colorectal cancer: a multicentre randomised controlled phase III trial.

BACKGROUND: Systemic adjuvant chemotherapy can improve overall survival and reduce the incidence of distant metastases for patients with advanced colon cancer. This study aimed to investigate whether regional chemotherapy (given by intraperitoneal or intraportal methods) combined with systemic chemotherapy was more effective than was systemic chemotherapy alone in terms of survival and recurrence for patients with stage II-III colorectal cancer. The study also compared systemic chemotherapy with fluorouracil and folinic acid with that of fluorouracil and levamisole. METHODS: During surgery, 753 patients with stage II-III colorectal cancer were randomly assigned to systemic chemotherapy alone (379 with fluorouracil and folinic acid, and 374 with fluorouracil and levamisole), and 748 to postoperative regional chemotherapy with fluorouracil followed by systemic chemotherapy with fluorouracil and folinic acid (n=368) or with fluorouracil and levamisole (n=380). Regional chemotherapy was given intraperitoneally (n=415) or intraportally (n=235) according to institution. The primary endpoint was 5-year overall survival. Secondary endpoints were 5-year disease-free survival and toxic effects. Analyses were by intention to treat. FINDINGS: Median follow-up was 6.8 years (range 0.0-10.1). 5-year overall survival was 72.3% (95% CI 69.0-75.6) for patients assigned regional and systemic chemotherapy, compared with 72.0% (68.7-75.3) for those assigned systemic chemotherapy alone (hazard ratio [HR] 0.97 [0.81-1.15], p=0.69). 5-year overall survival for all patients assigned fluorouracil and levamisole was 72.0% (68.7-75.2) compared with 72.3% (69.0-75.6) for all those assigned fluorouracil and folinic acid (HR 0.98 [0.82-1.17], p=0.81). The hazard ratios for 5-year disease-free survival were 0.94 (0.80-1.10) for regional versus non-regional treatment, and 0.92 (0.79-1.08) for all fluorouracil and levamisole versus fluorouracil and folinic acid. Grade 3-4 toxic effects were low in all groups. INTERPRETATION: Fluorouracil-based regional chemotherapy adds no further benefit to that obtained with systemic chemotherapy alone in patients with advanced colorectal cancer.

Secondary implantation of an artificial sphincter after abdominoperineal resection and pseudocontinent perineal colostomy for rectal cancer.

INTRODUCTION: Fecal continence with a perineal colostomy performed after abdominoperineal resection (APR) is not always satisfactory despite retrograde colonic enemas. Functional improvement is currently examined using artificial sphincters. Preliminary results are disclosed. PATIENTS: In 3 female patients, 45, 59 and 68 years old, curative APR and perineal colostomy were performed after radiotherapy in 2, for T1-2N0 cancer of the lower rectum. Due to occasional leaks, need for strict diet and fear of incontinence, an Acticon Neosphincter (AMS) was implanted consecutively at a mean 4.5 years after APR. RESULTS: Device implantation was feasible and uneventful. In one case, a superficial hematoma was drained and healed by second intention. Devices were activated 3 months after implantation. At a mean 2.5 years follow-up, the 3 patients had an activated and functional artificial sphincter. Leaks and fecal urgency significantly decreased but colonic enemas were maintained. Dietary restrictions were less and quality of life improved. All 3 considered the device as a useful adjunct. CONCLUSION: In this limited experience, implantation of artificial sphincter around a perineal colostomy following APR for rectal cancer appeared feasible and safe even in case of previous radiotherapy. Mid-term tolerance was satisfactory. Continence and quality of life significantly improved.

Surgical treatment of peritoneal carcinomatosis from well-differentiated digestive endocrine carcinomas.

BACKGROUND: The presence of peritoneal carcinomatosis (PC) in association with endocrine carcinomas (EC) is generally considered to have no impact on life expectancy, contrary to liver metastases. This study was aimed at assessing the actual prognostic impact of PC and to evaluate a new treatment with respect to survival times. PATIENTS AND METHODS: Among 111 patients undergoing surgery for progressive, well-differentiated EC, 37 (33%) presented a histologically proven PC, with synchronous liver metastases in 36 of them. The origin was ileal or appendiceal (carcinoid tumors) in at least 81% of cases. The patients were divided into 2 groups. Patients in group 1 (n = 20) could not undergo complete resection of PC, while those in group 2 (n = 17) underwent complete cytoreductive surgery, followed by immediate intraperitoneal chemotherapy. Partial hepatectomy was performed in 65% of patients in group 2. The median follow-up was 6.9 years. RESULTS: There was no postoperative mortality, and the morbidity rate was 47%. In group 1, 15 of the 20 patients died (5-year survival rate, 40.9%). Deaths were caused either by liver failure (60% of patients) or bowel obstruction from PC (40%). In group 2, six of the 17 patients died (5-year survival rate, 66.2%; P = .007). These patients died of liver failure (n = 4, 23.5%), bowel obstruction (n = 1, 5.8%), and cerebral hemorrhage (n = 1, 5.8%). CONCLUSIONS: PC associated with EC is not a rare event; it is mainly caused by carcinoid tumors and is always associated with liver metastases. When present, PC is the direct cause of death in 40% of patients if no specific treatment is undertaken. Treatment of PC with maximal cytoreductive surgery and immediate intraperitoneal chemotherapy appears promising, even though it can only be considered as palliative.

Hepatectomy plus intraoperative radiofrequency ablation and chemotherapy to treat technically unresectable multiple colorectal liver metastases.

BACKGROUND: Results and indications of intra-operative radiofrequency (RF) ablation of liver metastases (LM) are not well defined in the literature. AIM: To appreciate the survival rate of patients with strictly unresectable LM (defined on technical but not oncological criteria) when undergoing liver resection plus RF, along with optimal systemic chemotherapy. PATIENTS AND METHODS: Sixty three patients with technically unresectable LM (either >5, or bilateral with no sparing of at least one sector of the liver, or with tumor proximity to central major vascular structures) were treated. Extrahepatic metastases were also resected in 27% of patients. All patients received perioperative chemotherapy. The median follow-up was 27.6 months (range: 15-74). RESULTS: There was no postoperative mortality and the morbidity rate was 27%. The 2-year overall survival rate of the 63 patients was 67% with a median survival of 36 months. The local recurrence rates were similar for the three types of local treatments: 7.1% for the 154 RF ablations, 7.2% for the 55 wedge resections, and 9% for the 44 segmental anatomic resections (P = 0.216). Hepatic recurrences occurred in 71% of patients. CONCLUSION: The combination of anatomic segmental and wedge resections, RF ablation, and optimal chemotherapy in patients with technically unresectable LM results in a median survival of 36 months.

[Salvage surgery for anal canal carcinomas]. / Chirurgie de rattrapage pour les carcinomes du canal anal.

The standard treatment of epidermoid carcinoma of the anal canal consists of radiotherapy or chemoradiotherapy. The recommended salvage treatment for local failures relies on abdominoperineal resection and permits a 5-year overall survival rate around 50%. However, the morbidity associated with this surgery is important with regard to delayed perineal wound healing. New techniques for perineal reconstruction offer interesting solutions to limit this morbidity. Musculocutaneous flaps permit to fill the perineal wound left after the resection and in some cases to reconstruct the posterior vaginal wall. Although less popular, the construction of a pseudocontinent perineal colostomy enables some patients to avoid a permanent iliac colostomy. The surgical excision of metastatic inguinal nodes, followed by radiotherapy, is an alternative to radiotherapy alone. Surgery can also be performed after failure of radiotherapy, at the cost of an increased morbidity.

Pancreatic metastases: a multicentric study of 22 patients.

AIMS OF THE STUDY: To evaluate the diagnosis, treatment and outcome of patients with pancreatic metastases. PATIENTS AND METHODS: We retrospectively reviewed the records of patients with pancreatic metastasis managed in the Paris area between 1990 and 2000. RESULTS: The series analyzed included 22 patients, 10 men and 12 women, mean age 61 years (range: 35-76). The primary tumors were renal-cell carcinoma (N=10), colorectal cancer (N=4), lung cancer (N=4), breast cancer (N=2), cutaneous melanoma (N=1) and ileal carcinoid (N=1). The mean interval between primary treatment and presentation was 73.5 months (range: 2-151). Diagnosis was established because of clinical symptoms (N=15) or during surveillance (N=7). Computed tomography (N=19) and endoscopic ultrasound (EUS) (N=18) mainly showed solitary and hypodense/or hypoechoic masses. Histological diagnosis was obtained before surgery by EUS-guided fine needle aspiration (N=6), ultrasound-guided biopsy (N=3) or duodenoscopy (N=3). Among 10 patients with primary renal-cell carcinoma, 7 were treated by surgery. Median global survival was 33 months. Median survival was 61 months in the event of surgical treatment and 20 months in the other patients (ns). Mean survival depended on the type of primary tumor, 61 months for renal-cell carcinoma and 33 for colorectal cancer (P=0.06). CONCLUSIONS: Most pancreatic metastases develop from renal-cell carcinoma and can occur several years after nephrectomy. Histological diagnosis is often obtained before surgery. Surgical resection must be discussed as it can allow long-term survival.
