The Role of Metastasectomy in Renal Cell Carcinoma in the Era of Targeted Therapy

Despite contemporary innovations in systemic therapy and surgical treatment, renal cell carcinoma (RCC) remains the most lethal urologic malignancy. Still, around 20 % of patients with RCC present with metastases at diagnosis, and 40–50 % of those with localized advanced disease will ultimately progress to metastatic disease. Although the new, targeted therapy paradigms have changed the treatment of patients with advanced RCC and offer prolonged survival, cure is extremely uncommon in the absence of surgical resections. In this paper, the current role of metastasectomy is reviewed. Searches were carried out in the PubMed database and the Cochrane Library of Controlled Clinical Trials. While there is no randomized study available, recent large observational studies have better defined the prognosis of patients with metastatic RCC with or without metastasectomy. In multivariate analysis, independent predictive factors included male gender, disease-free interval > 1 year, single metastatic site and complete metastasectomy. Other reports from selected patient materials show 29–31 % 5-year overall survival rates. In patients with recurrent disease after resection of a lung metastasis, 60 % were able to undergo a subsequent resection, compared with 25 % with recurrent bone metastasis. Also, metastasectomy after initial systemic therapy gave partial or complete response in a majority of patients. In these patients, the median survival was 4.7 years and 21 % remained free of disease at last follow-up. Patients with metastatic renal cell carcinoma should be considered for multimodal therapy, including surgery of metastatic lesions. A proportion of patients will achieve long-term survival with aggressive surgical resection.     

Surgical Resection of Gastrointestinal Stromal Tumors After Treatment with Imatinib

Background Surgical resection of gastrointestinal stromal tumors (GISTs) has been the most effective therapy for these rare tumors. Imatinib has been introduced as systemic therapy for locally advanced and metastatic GIST. In this study, the surgical resection rates and long-term outcomes of patients treated with preoperative imatinib for locally advanced primary, recurrent, or metastatic GISTs were evaluated. Methods Patients were retrospectively assessed for completeness of surgical resection and for disease-free and overall survival after resection. Results Forty-six patients underwent surgery after treatment with imatinib. Eleven were treated for locally advanced primary GISTs for a median of 11.9 months, followed by complete surgical resection. All eleven were alive at a median of 19.5 months, and ten were free of disease. Thirty-five patients were treated for recurrent or metastatic GIST. Of these, eleven underwent complete resection. Six of the eleven patients had recurrent disease at a median of 15.1 months. All eleven patients were alive at a median of 30.7 months. Patients with a partial radiographic tumor response to imatinib had significantly higher complete resection rates than patients with progressive disease (91% vs. 4%; P < .001). Of the 24 patients with incomplete resection, 18 initially responded to imatinib but were unable to undergo complete resection after they progressed before surgery. Conclusions Preoperative imatinib can decrease tumor volume and is associated with complete surgical resection in locally advanced primary GISTs. Early surgical intervention should be considered for imatinib-responsive recurrent or metastatic GIST, since complete resection is rarely achieved once tumor progression occurs.

Selected Patients with Metastatic Melanoma May Benefit from Liver Resection

Background In the last few years there has been expanding use of hepatic resection for non-colorectal metastases. The purpose of this study is to evaluate the experience of liver resection for patients with metastatic melanoma. Methods Eighteen patients with metastatic melanoma were explored for possible surgical resection. All patients fitted the following criteria: absence of extra-hepatic disease after evaluation with CT/MRI and FDG-PET scans; disease-free interval longer than 24 months after the resection of the primary melanoma; presumed completely resectable lesions; absence of clinical co-morbidities. Results Liver resection was performed in 10 patients; 8 out of 18 presented with irresectable tumors and/or peritoneal metastases and were not operated. One patient presented with postoperative biliary fistula and was conservatively managed. No other complications or postoperative mortality were observed. After a mean follow-up of 25.4 months, 5 patients are alive and without evidence of recurrence. Overall median survival was 22 months; overall survival and disease-free survival were 70% and 50% respectively. Conclusions Resection of liver metastases from melanoma in a selected group of patients may increase survival. Exploratory laparoscopy should be included in the preoperative armamentarium of diagnostic tools.     

Carcinoma de células renales con extensión a vena cava: puesta al día y revisión de nuestra casuística

ObjectiveTo assess current management of renal cell carcinoma (RCC) extending into the inferior vena cava (IVC): staging, diagnosis, surgical approach, adjuvant therapy, prognostic factors and survival rate.Materials and methodsNineteen cases of RCC extending into the IVC undergoing surgical resection from January 1988 to August 2008 were reviewed. TNM staging and Neves-Zincke grading of the tumor were also assessed. Surgical approach depended on thrombus level.ResultsWith a perioperative mortality rate of 10.5% and a mean follow-up of 22.65 months (range 2-79), 5 patients are still alive, while 11 patients died from the disease, 1 from an unrelated cause, and 2 were lost to follow-up. Patients with metastatic disease received adjuvant treatment with immunotherapy or kinase inhibitors. Mean survival was 15.1 months. Significant differences were found in 3- and 5-year survival rates in patients staged as n0m0 as compared to all other stages (n+m0, n0m+, n+m+). no differences were found depending on thrombus level.ConclusionsRCC with thrombus in the IVC is a tumor with a high mortality rate. Surgery continues to be the best option, and requires adequate preoperative evaluation and the support of an experienced and well trained multidisciplinary team. Survival depends on disease extension.     

Surgeon's role in the management of solitary renal cell carcinoma metastases occurring subsequent to initial curative nephrectomy: An institutional review

Background: Solitary metastases from a primary renal cell carcinoma (RCC) occur in <10% of patients with metastatic RCC. To date, the benefit of surgically resecting such apparently solitary lesions has not been well documented. Materials and Methods: Forty-one patients (25 men, 16 women) with metastatic renal cell carcinoma treated by surgical excision of solitary metastases (1970–1990) were retrospectively reviewed. They comprised 9% of patients with metastatic hypernephroma seen during this period. All patients had undergone previous curative nephrectomy with a median disease-free interval of 27 months. Patients with skeletal, spinal cord, and lymph node metastases were excluded. Results: Mevtastases were intrathoracic (n=20), intracranial (n=7), and intraabdominal or in the extrapleural chest wall soft tissue (n=10). Three patients had metastases to the thyroid gland and one had a solitary metastasis to an index finger. Median follow-up was 3.2 years. Complete resection was possible in 36 patients (88%) with a single lesion excised in 23 of these 36 patients (64%). There was no operative mortality. Predicted survival from the date of complete resection of metastases was 77%, 59%, and 31% at 1, 3, and 5 years, respectively, with a median survival of 3.4 years. One patient is alive without evidence of recurrent tumor 93 months from the first of 12 complete surgical resections. Varying adjuvant therapy was used in 50% of the patients. An increased histological tumor grade of the metastatic lesion relative to the original RCC was the only significant prognostic indicator identified. Disease-free interval and number of resected lesions were not significantly associated with patient survival. Conclusion: A small fraction of renal cell carcinoma patients are candidates for potentially curative surgical resection of solitary metastatic lesions. Excision of such lesions may contribute to prolonged survival in selected instances. The results of this study were presented at the 46th Annual Cancer Symposium of The Society of Surgical Oncology, Los Angeles, California, March 18–21, 1993.     

Preoperative radiation and chemotherapy in the treatment of adenocarcinoma of the rectum.

OBJECTIVE: In this study, the impact of preoperative chemotherapy and radiation on the histopathology of a subgroup of patients with rectal adenocarcinoma was examined. As well, survival, disease-free survival and pelvic recurrence rates were examined, and compared with a concurrent control group. SUMMARY BACKGROUND DATA: The optimal treatment of large rectal carcinomas remains controversial; current therapy usually involves abdominoperineal resection plus postoperative chemoradiation; the combination can be associated with significant postoperative morbidity. In spite of these measures, local recurrences and distant metastases continue as serious problems. METHODS: Fluorouracil, cisplatin, and 4500 cGy were administered preoperatively over a 5-week period, before definitive surgical resection in 43 patients. In this group of patients, all 43 had biopsy-proven lesions > 3 cm (median diameter), involving the entire rectal wall (as determined by sigmoidoscopy and computed tomography scan), with no evidence of extrapelvic disease. The patients ranged from 31 to 81 years of age (median 61 years), with a male:female ratio of 3:1. A concurrent control group consisting of 56 patients (median: 62 years, male:female ration of 3:2) with T2 and T3 lesions was used to compare survival, disease-free survival, and pelvic recurrence rates. RESULTS: The preoperative chemoradiation therapy was well tolerated, with no major complications. All patients underwent repeat sigmoidoscopy before surgery; none of the lesions progressed while patients underwent therapy, and 22 (51%) were determined to have complete clinical response. At the time of resection, 21 patients (49%) had gross disease, 9 (22%) patients had only residual microscopic disease, and 11 (27%) had sterile specimens. Of the 30 patients with evidence of residual disease, 4 had positive lymph nodes. In follow-up, 39 of the 43 remain alive (median follow-up = 25 months), and only 1 of the 11 patients with complete histologic response developed recurrent disease. Six of the 32 patients with residual disease (2 with positive nodes) have developed metastatic disease in follow-up (median time to diagnosis 10 months, range 3-15 months). Three of these patients with metastases have died (median survival after diagnosis of metastases = 36 months). Local recurrence was seen in only 2 of 43 patients (< 5%). Cox-Mantel analysis of Kaplan-Meier distributions demonstrated increased survival (p = 0.017), increased disease-free survival (p = 0.046), and decreased pelvic recurrence (p = 0.031) for protocol versus control patients. CONCLUSIONS: This therapeutic regimen has provided enhanced local control and decreased metastases. Furthermore, the marked degree of tumor downstaging, as seen by a 27% incidence of sterile pathologic specimens and a low rate of positive lymph nodes in this group with initially advanced lesions, strongly suggest that less radical surgery and sphincter preservation may be used with increasing frequency.     

Interleukin-2, interferon-alpha and 5-fluorouracil immunotherapy for metastatic renal cell carcinoma: the all Ireland experience

OBJECTIVE: To analyse the long-term efficacy of combined interferon-alpha (IFN-alpha) and interleukin-2 (IL-2) subcutaneously, with 5-fluorouracil (5-FU) intravenously in a general multicentre setting, as treatment for metastatic renal cell carcinoma (RCC). METHODS: Fifty-nine patients with metastatic RCC were scheduled to receive an 8-week cycle of immunotherapy. Karnofsky score ranged from 70 to 100 (median 90). Thirty-one patients at presentation had metastases of which 14 underwent nephrectomy. Metastases occurred in multiple organs (lung 74%, mediastinal lymphadenopathy 22%, bone 21%). Therapeutic response and survival were analysed. RESULTS: Nine patients died from disease progression prior to completion of one full cycle. Six cases (10%) have stable disease at a follow-up of 51 months (range 20-88 months). Currently 11 patients (19%) are alive at a mean follow-up of 45 months (range 18-88 months). Forty-eight patients (81%) died of their disease at a mean follow-up of 10 months (range 0.5-46 months). Survival rate at 1 year was 53%, at 2 years 21%, at 3 years 16% and at 5 years 5%. Overall median survival is 10 months. CONCLUSION: IL-2 and IFN-alpha with 5-FU based immunotherapy achieve durable survival rates at 3 years in a minority of patients. Addition of 5-FU does not increase survival in our group. This study population is very different to other reported series. However it reflects better the entire population with metastatic RCC though results are subsequently poorer. Identifying patients that will respond is paramount.     

Compatibility, indications, and limits of nerve sparing technique in lateral pelvic lymphadenectomy for advanced rectal carcinoma

The aim of radical surgical treatment of rectal cancer is to control the spread and prevent recurrence of the disease. In an attempt to improve the results of treatment of locally advanced rectal cancer, we advocate an extended surgical approach consisting of total mesorectal excision, lateral pelvic lymphadenectomy and the nerve sparing technique with resection of autonomic nerves whenever these fibers are affected by locally advanced tumor. Nine cases (9.2%) in a personal series of 98 patients with rectal carcinoma, operated on over the period from January 1992 to December 1997, underwent total mesorectal excision, lateral pelvic lymphadenectomy and the nerve sparing technique procedures for locally advanced extraperitoneal disease. In 7 patients with stage II or III disease, the 5-year survival rate was 80% and the 5-year disease-free survival rate 66.7% after a mean follow-up of 55 months. None of them experienced local recurrence, but one patient died of diffuse metastatic disease 50 months after surgery. One patient with stage IV rectal cancer died of disease 13 months postoperatively, while another patient with the same stage of disease is still alive with disease 26 months after surgery. One patient underwent liver resection for a solitary metastasis 25 months after the primary operation. Two patients suffered postoperatively from urinary retention with mild irregular flow at urodynamic testing, but no long-term urinary disturbances persisted. Retrograde ejaculation occurred postoperatively in one of the two patients who experienced urinary disorders, and another patient had erection disturbances. These sexual dysfunctions did not improve during long-term follow-up. Total mesorectal excision, lateral pelvic lymphadenectomy, and the nerve sparing technique, with resection of the autonomic nerves whenever these fibers are involved, allow satisfactory results to be achieved in terms of survival and functional outcome in patients with locally advanced rectal cancer. In western subjects, however, this procedure is safe only after careful patient selection.     

Paget's sarcoma: limb salvage by custom mega prosthesis: four case reports

Of 4 Paget's sarcoma patients (age range, 55-68 years) underwent limb salvage surgery by custom mega prosthesis, 3 had lesions in the upper extremity and one in the proximal femur. Three of the patients were at stage IIB of the disease, according to Enneking's system of staging musculoskeletal tumours. All 4 patients underwent wide resection with a mean length of 152.5 mm. The defects were reconstructed with custom-made prostheses: proximal humeral prostheses in 2 of the patients, total elbow prosthesis in one, and total hip prosthesis in one. During a mean postoperative follow-up period of 40 months, one died of disseminated disease 14 months after surgery; one remained disease-free; 2 had local recurrence and required amputation, of whom one died of disseminated disease one year after amputation, the other had no further evidence of the disease. We report the functional outcomes of the 2 patients who were alive at the latest follow-up. The 2-year patient survival rate was 50%.     

Repeat hepatic resections for metastatic colorectal cancer.

OBJECTIVE: The authors weighed the risks and benefits of repeat liver resections for colorectal metastatic disease. METHOD: In the 6-year period between January 1985 and June 1991, 499 patients underwent liver resections for colorectal metastases at the Memorial Sloan-Kettering Cancer Center. Of these, 25 patients had repeat surgical resections for isolated recurrent disease to the liver. The clinical data for these patients were reviewed. RESULTS: The median interval between the two resections was 11 months. There were no perioperative deaths, and the complication rate was 28%. Median follow-up after the second liver resection is 19 months, with median survival of 17 months for nonsurvivors. Although the median survival after the second resection is 30 months, 20 of the 25 patients have had recurrences with a median disease-free interval of only 9 months. No characteristic of primary or metastatic disease predicted outcome, including time between presentation of the primary and development of liver metastases, disease-free interval after the first liver resection, and bilobar liver involvement. CONCLUSIONS: Although repeat liver resections can be performed safely and improves survival, the likelihood of cure from such resection therapy is low. This likelihood of further recurrences encourage studies of adjuvant or alternative treatments of this population.     

Recurrent metastatic renal cell carcinoma presenting as a bleeding gastric ulcer after a complete response to high-dose interleukin-2 treatment

Immunotherapy with high-dose recombinant interleukin-2 is an effective therapy for selected patients with metastatic renal cell carcinoma (RCC). Objective responses (complete or partial) are observed in about 15% of treated patients. The overall and disease-free survival of patients with a complete response are significantly prolonged. Although RCC is known to spread hematogenously, isolated RCC metastasis to the stomach is a rare event. Recurrent RCC, after a complete response to interleukin-2, presenting clinically as an isolated gastric metastasis, has not been reported to date. In this report, we describe the clinical course of a patient with metastatic RCC who had a complete response to high-dose interleukin-2 and was disease free for 4 years before presenting with massive upper gastrointestinal hemorrhage due to an isolated gastric metastasis. The patient remained disease free for 3 years after resection of the metastasis. Metastatic RCC to the stomach, although rare, should be suspected in any patient with a history of RCC who presents with gastrointestinal symptoms. In the absence of diffuse disease, aggressive therapy, including surgical resection, is appropriate for isolated gastric metastasis, because prolonged survival is possible.     

Contralateral adrenal metastasis of renal cell carcinoma: treatment,outcome and a review

OBJECTIVE: To report the surgical treatment of patients with renal cell carcinoma (RCC) metastatic to the contralateral adrenal gland and compare our experience with previous reports, as such metastases are found in 2.5% of patients with metastatic RCC at autopsy, and the role of resecting metastatic RCC at this site is not well defined. PATIENTS AND METHODS: We retrospectively identified 11 patients who had surgery for metastatic RCC to the contralateral adrenal gland between October 1978 and April 2001. The patients' medical records were reviewed for clinical, surgical and pathological features, and the patients' outcome. RESULTS: The mean (median, range) age of the patients at primary nephrectomy was 60.9 (64, 43-79) years; all had clear cell (conventional) RCC. Synchronous contralateral adrenal metastasis occurred in two patients. The mean (median, range) time to contralateral adrenal metastasis after primary nephrectomy for the remaining nine patients was 5.2 (6.1, 0.8-9.2) years. All patients were treated with adrenalectomy; there were no perioperative complications or mortality. Seven patients died from RCC at a mean (median, range) of 3.9 (3.7, 0.2-10) years after adrenalectomy for contralateral adrenal metastasis; one died from other causes at 3.4 years, one from an unknown cause at 1.7 years and two were still alive at the last follow-up. CONCLUSIONS: The surgical resection of contralateral adrenal metastasis from RCC is safe; although most patients died from RCC, survival may be prolonged in individual patients. Hence, in the era of cytoreductive surgery, the removal of solitary contralateral adrenal metastasis seems to be indicated.     

Chemotherapy and radiation therapy before transhiatal esophagectomy for esophageal carcinoma

Recent efforts to improve survival in patients with esophageal carcinoma have combined both systemic and local therapy. From October 1985 to October 1987, 43 patients with local-regional esophageal cancer (adenocarcinoma in 21, squamous cell in 22) were treated with cisplatin, vinblastine, and 5-fluorouracil chemotherapy concurrent with 4,500 cGy radiation therapy for 21 days before transhiatal esophagectomy 3 weeks later. Two patients died of chemotherapy/radiation therapy toxicity. Forty-one completed preoperative chemotherapy/radiation therapy. At operation, 2 patients had incurable metastatic disease; 39 underwent transhiatal esophagectomy. Eleven patients had no residual tumor in the resected specimen for a 27% (11 of 41) pathological complete response rate. Preoperative chemotherapy/radiation therapy resulted in no increased perioperative morbidity as compared with our historical controls. One patient died postoperatively of an unrecognized brain metastasis (2% operative morbidity). At a median follow-up of 27 months, 20 patients (47%) are alive and clinically disease-free and 21 have died, 19 from progression of their carcinoma. The median survival time for all 43 patients is 29 months (Kaplan-Meier estimate), and cumulative survival is 72% at 12 months, 60% at 24 months, and 46% at 36 months. All 11 patients with a complete response are alive at a median follow-up of 36 months, and all are disease-free. The 2-year survival of 60% of this group as compared with 32% in our earlier patients treated with transhiatal esophagectomy alone suggests that intensive combined modality therapy improves survival in these patients. A randomized prospective trial is now in progress.     

Late relapse of metastatic testicular nonseminomatous germ cell cancer: surgery is needed for cure

OBJECTIVE: To identify patients with late relapse of metastatic, nonseminomatous germ cell tumour (NSGCT) and to evaluate the patterns of relapse, treatment and outcome, as such relapse at >2 years after complete remission to treatment for metastatic disease (late relapse) is uncommon, but with prolonged follow-up is becoming increasingly recognized. PATIENTS AND METHODS: Between 1980 and 2004, 1405 patients with testicular GCTs were identified who presented to Southampton University Hospital; 742 had NSGCTs or combined testicular GCTs, of whom 405 received primary chemotherapy for metastatic disease. In all, 329 (81%) patients achieved a complete response (CR) to initial treatment, with 101 of them (31%) requiring surgical resection of residual masses after chemotherapy. Any patient relapsing at >2 years after a CR to initial treatment (late relapse) was assessed in detail. RESULTS: In all, 20 patients had a late relapse, 17 of whom received initial treatment locally and three of whom were initially treated elsewhere. Most (65%) late relapses were asymptomatic and detected by routine cross-sectional imaging or rising levels of tumour markers. Late relapse occurred at a median (range) of 108 (26-217) months (approximately 9 years) after CR. Fifteen (75%) patients underwent only surgery for late relapse, including five who had invasive malignant germ cell cancer within the resected specimens. Fourteen of 15 surgically treated patients remained alive at a median of 44 (9-184) months from initial treatment for late relapse; one had died with progressive recurrent germ cell/epithelial malignancy. Five (25%) patients were initially treated with chemotherapy for late relapse; three of them died from progressive germ cell cancer and the two survivors both had surgical excision of residual abnormalities after salvage chemotherapy. Overall, 15 of 20 (75%) men remain alive with no evidence of disease; one further patient is currently undergoing salvage treatment for his third relapse. CONCLUSION: Late relapse is uncommon after modern therapy for metastatic GCTs. Surgical treatment for localized disease, where possible, is associated with prolonged disease-free and overall survival. By contrast, chemotherapy is associated with a low response rate and a poor outcome.     

Sacropelvic resection for recurrent anorectal cancer. A multidisciplinary approach

A multimodal approach including preoperative external beam radiation, surgical resection, and intraoperative electron radiation was used in 23 patients with locally advanced anal or recurrent rectal cancers involving the sacrum. The proximal extent of complete sacral resection was S2 in three patients, S3 in 12 patients, S4 in two patients, and S5 in one patient. The tumor was confined to the anterior sacral cortex in five patients. The resection was marginal in 10, contaminated marginal in 11, and intralesional in two patients. At 19 to 54 months of followup, five patients are alive without evidence of disease and four are alive with disease. Twelve patients died of their disease, and two died of other causes. There was a mean survival of 32.9 months for the patients who were alive at followup. Kaplan-Meier survival for all patients was 82% at 1 year and 73% at 2 years, with death of disease as an endpoint. Thirteen (57%) patients had another local recurrence develop at a mean of 17.2 months. Eight (35%) patients had metastatic disease develop at a mean of 16.3 months. Proper patients selection is important in ensuring a favorable outcome from this aggressive surgery.     

The growing teratoma syndrome

Thirteen patients with metastatic non-seminomatous germ cell tumours and enlarging metastases consisting of teratoma differentiated only were identified. Patients were managed with surgical resection soon after the growing lesions were documented. Surgical morbidity was minimal and 12 patients are alive (10 are disease-free) at a median follow-up of 28 months.     

Pancreatic Secondary Lesions from Renal Cell Carcinoma

Background

Metastatic lesions to the pancreas are uncommon. The most frequent metastases are from renal cell carcinoma (RCC). We analyzed the clinical features and survival of patients with pancreatic metastasis from renal cell carcinoma.

Methods

We retrospectively reviewed the clinical records of patients with pancreatic metastases from RCC, observed in our department from January 2004 to March 2010. Follow-up continued to September 2013.

Results

In the study period 13 patients with a diagnosis of metastasis from RCC were observed in our clinic, and among them 9 pancreatic resections were performed (2 pancreaticoduodenectomy, 1 duodenum-preserving pancreatic head resection, 1 central pancreatectomy, and 5 distal pancreatectomy). Four patients did not undergo a pancreatic resection: two refused surgery, one had an endoscopic biliary stent for jaundice placed and then underwent a surgical biliary bypass, and the fourth patient was too advanced and had only an endoscopic biliary stent. The mean follow-up was 56 months (range  5–115, median  53), with one nonresected patient lost in follow-up after 38 months. Among the other 12 patients, 4 died: two for progression of disease 5 and 20 months respectively after our observation. The mean (±SEM) disease-free survival of seven resected patients with curative intent was 40 ± 11 months (median  34).

Conclusions

Pancreatic metastases from RCC are often asymptomatic. They generally present slow growth and an indolent behavior. Surgery is the treatment of choice in those patients with only pancreatic involvement, achieving long-term survival and disease-free survival.     

Experience with fossa recurrence of renal cell carcinoma.

We describe the surgical management and followup of 11 patients with local recurrence of renal cell carcinoma in the renal fossa, 10 of whom demonstrated no evidence of distant metastatic disease at the time of recurrence. Average interval to recurrence was 31 months from nephrectomy, with the majority of patients presenting with symptoms of weight loss, fatigue and lumbar discomfort. A total of 13 resections of recurrent carcinoma was performed with 3 immediate postoperative complications, including a retroperitoneal abscess, jejunal necrosis requiring resection and a duodenal obstruction requiring duodenojejunostomy. There were 2 postoperative deaths, 2 patients died of disseminated disease at 8 and 22 months, and 3 died of causes unrelated to cancer recurrence at 4 months, 6 months and 10 years. Four patients were without disease at a followup of 35, 46, 48 and 211 months. We include in this review a report on 1 patient who maintains a disease-free survival of 17 years after resection of a recurrent spindle cell carcinoma. We conclude that an aggressive surgical approach to recurrent renal cell carcinoma within the renal fossa can produce long-term disease-free survival and is justified when compared to the results reported for chemotherapy.     

Trimodality therapy for advanced gallbladder cancer

We conducted a retrospective review of all patients who underwent surgical extirpation for stage III, stage IV, or recurrent carcinoma of the gallbladder. Between 1991 and 1999 ten patients underwent surgical resection for advanced gallbladder cancer. All patients received adjuvant therapy either pre- or postoperatively. Radiotherapy was used in all patients and chemotherapy in 90 per cent of patients. Two patients subsequently underwent resection for locally recurrent disease. An additional patient with stage II disease initially was also treated surgically for a local recurrence. Surgical management involved cholecystectomy and resection of various amounts of liver surrounding the gallbladder bed and regional lymphadenectomy. Contiguously involved structures were resected en bloc. Resection of recurrent disease included excision of all gross tumor. The median overall survival excluding the one 30-day mortality was 53.6 months (range 8-73 months). Four patients have survived 4 or more years, and currently four patients are alive and disease free at 73, 49, 33, and 8 months. Median disease-free interval after each resection of recurrent disease was 13.8 months (range 4-28 months). We conclude that trimodality therapy in selected patients with stage III, IV, or recurrent carcinoma of the gallbladder is possible and may result in prolonged survival.     

Metastasis to the pancreas—an indication for pancreatic resection?

Background and aims Isolated metastatic involvement of the pancreas is very rare. To evaluate the possible benefit of surgery, we retrospectively analyzed patients that underwent pancreatic resection for metastases into the pancreas. Patients/methods In 12 patients (8 men and 4 women), metastatic disease was treated by pancreatic resection (two total pancreatectomies, nine pylorus-sparing duodenopancreatectomies, and one left-side pancreatic resection) between 1993 and 2005 at our institution. Primary malignomas were renal cell carcinoma (RCC; n = 7), malignant melanoma (n = 4), and colon cancer (n = 1). All patients were followed-up until November 2006 or until death. Results Complications requiring relaparotomy were found in two patients (retroperitoneal abscess and bile fistula), whereas one patient with pancreatic fistula could be treated by conservative measures. There was no perioperative mortality. Median survival time was 51 months (5–105 months). At the end of follow-up, seven patients were alive at 12 to 86 months, whereas five died between 5 and 105 months: four died of the disease, and one patient died of cardiac failure without evidence of recurrent cancer. Conclusion Patients with isolated pancreatic metastasis particularly of RCC benefit from surgery. Pancreatic resection may achieve long-term survival or good palliation in selected cases of other primaries as well.
