Management of Neck Metastasis with Carotid Artery Involvement,

THE LARYNGOSCOPE, Issue 1 2004
Stephen B. Freeman MD
Abstract Objectives To demonstrate aggressive management of neck metastasis adherent to the internal or common carotid artery using sound oncologic principles while minimizing the significant risk of complications. Study Design Our 13 year experience of treating patients with recurrent or residual neck metastasis adherent to the internal or common carotid artery was retrospectively reviewed. Methods Angiography was used in patients who demonstrated fixation of the carotid artery on examination or imaging, followed by balloon test occlusion and single photon emission computer tomography (SPECT) scanning. The majority of carotid resections were reconstructed with a vein graft, especially if there was insufficient collateral cerebral circulation. Radical resection of the soft tissue including the carotid artery was performed followed by 15 to 20 Gray of electron beam delivered directly to the deep tissue. More recently, the carotid has been permanently occluded preoperatively, if possible. The assessment of the cerebral circulation and management of the carotid artery were analyzed as was survival, site of recurrence, and complications. Results Fifty-eight charts were reviewed. The majority of patients (41) had their carotid artery reconstructed at time of resection, and the remaining had either the artery ligated or permanently occluded preoperatively. Strokes occurred in 11 patients. The median disease-specific survival was 12 months, with 24% of patients dying from distant metastasis. Conclusions The high risk of complications, loss of life's quality, and mortality must be balanced against the natural history of the disease if left untreated. The decision is a heavy burden for the patient, family, and head and neck surgeon. [source]


Management of advanced mandibular osteoradionecrosis with free flap reconstruction

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 10 2001
David W. Chang MD
Abstract Background The purpose of this study was to assess the effectiveness of free tissue transfer for treatment of advanced mandibular osteoradionecrosis (ORN) in head and neck cancer patients. Methods We reviewed 29 patients who were treated for advanced mandibular ORN by radical resection and reconstruction with free flaps at our institution. All patients had either failed to respond to conservative treatment, including hyperbaric oxygen therapy and debridement or had pathological fracture due to ORN. Results Twenty-four vascularized bone (17 fibula, five iliac, and two scapula), four rectus abdominis myocutaneous, and one radial forearm fasciocutaneous free flaps were used. The complications occurred in 6 of 29 patients (21%). A total of four flaps (14%) were lost. The mean follow-up was 2 years 9 months. All patients had complete resolution of ORN symptoms. No evidence of ORN recurrence was observed in any patient. Conclusion For advanced osteoradionecrosis of the mandible, radical resection followed by reconstruction using free flap provides a reliable means of obtaining good wound healing with acceptable aesthetic and functional results. © 2001 John Wiley & Sons, Inc.

Resection of hilar cholangiocarcinoma with left hepatectomy after pre-operative embolization of the proper hepatic artery

HPB, Issue 2 2010
Yoshikazu Yasuda
Abstract Background:, Right or right-extended hepatectomy including the caudate lobe is the most common treatment for hilar cholangiocarcinoma (HC). A 5-year survival of up to 60% can be achieved using this procedure if R0-resection is obtained. However, for some patients a left-sided liver resection is necessary to obtain radical resection. The close relationship between the right hepatic artery and the HC in these patients frequently limits the ability to achieve a radial R0-resection without difficult vascular reconstruction. The aim of the present study was to describe the outcome of patients who underwent pre-operative embolization of the proper hepatic artery in an effort to induce development of arterial collaterals thus allowing the resection of the proper and right hepatic artery without vascular reconstruction. Methods:, In patients presenting with HC who were considered to require a left hepatic lobectomy and in whom pre-operative work up revealed possible tumour invasion of the right hepatic artery, transcatheter arterial embolization (TAE) of the proper hepatic artery or the left and right hepatic arteries was performed. Three weeks later, a left-sided hepatectomy with resection of all portal structures except the portal vein was performed. Results:, In six patients, pre-operative embolization of the proper hepatic artery was performed. Almost instantaneously in all six patients arterial flow signals could be detected in the liver using Doppler ultrasonography. No patient died peri-operatively. In all six patients an R0 radial resection was achieved and in three an R0 proximal transection margin was obtained. All post-operative complications were managed successfully using percutaneous drainage procedures. No patient developed local recurrence and two patients remain disease free more than 7 years after surgery. Summary:, After pre-operative embolization of the proper hepatic artery, resection of the HC with left hepatectomy is a promising new approach for these technically demanding patients, giving them the chance of a cure.

Prognostic value of p27kip1 expression in adenocarcinoma of the pancreatic head region

HPB, Issue 3 2006
Jerzy Mielko
Abstract Background. p27kip1 is a tumour suppressor gene, functioning as a cyclin-dependent kinase inhibitor, and an independent prognostic factor in breast, colon, and prostate adenocarcinomas. Conflicting data are reported for adenocarcinoma of the pancreas. The aim of this study was to establish the prognostic value of p27kip1 expression in adenocarcinoma of the pancreatic head region. Patients and methods. The study included 45 patients (male/female ratio 2:1; mean age 59, range 38,82 years) with adenocarcinomas of the pancreatic head region: 24 , pancreatic head, 18 , periampullary and 3 , uncinate process. The patients underwent the Kausch-Whipple pancreatoduodenectomy (n=39), pylorus-preserving pancreatoduodenectomy (n=5), or nearly total pancreatectomy (n=1). Eight patients received adjuvant chemotherapy postoperatively. Follow-up time ranged from 3 to 60 months. Tumours were staged according to the pTNM classification (UICC 1997). Immunohistochemistry was done on paraffin-embedded blocks from tumour sections. Quantitative determination of p27kip1 expression was based on the proportion of p27kip1 -positive cells (< 5%= negative). Survival analysis was carried out using the Kaplan-Meier method and Cox regression model. Results. Positive p27kip1 expression was detected in 22 tumours (49%), whereas 23 tumours (51%) were p27kip1 -negative. There were no significant correlations between p27kip1 index and stage or lymph node involvement. Median survival time in patients with p27kip1 -positive tumours was 19 months, whereas in patients with p27kip1 -negative tumours it was 18 months (p=0.53). A significant relationship was found between p27kip1 -negative tumours and radical resection (p=0.04). Multivariate survival analysis revealed that the localization of the tumour (pancreatic head/uncinate process vs periampullary) was the only significant and independent prognosticator (p=0.01, Cox regression model). Resection margins involvement and grade remained nearly significant prognostic factors (p=0.07 and p=0.09, respectively). Conclusion. We conclude that p27kip1 has limited overall prognostic utility in resected carcinoma of the pancreatic head region, but its potential role as a marker of residual disease needs to be further assessed.

A salvage treatment for solid liver metastasis after radical resection of Klatskin tumour

HPB, Issue 4 2003
Yuji Nakagawa
Background Long-term survival has not been described following surgical resection for liver metastasis after radical resection of an advanced hilar bile duct carcinoma (Klatskin tumour). One such patient who developed liver metastasis after radical treatment for stage IVA (pTNM) hilar cholangiocarcinoma has survived 5.5 years after resection of the liver metastasis followed by chemotherapy. Case report A 50-year-old man developed a solid liver metastasis in segment VIII 17 months after radical resection of a stage IVA (pT3 pN1 M0) Klatskin tumour followed by postoperative radiotherapy (54 Gy) and systemic chemotherapy (oral UFT 450 mg/day plus intravenous cisplatin 20 mg on 5 consecutive days each month). The patient is alive at 7 years after the primary resection followed by resection of the liver metastasis plus further systemic chemotherapy comprising oral UFT combined with intravenous adriamycin (ADM) and mitomycin C (MMC). Conclusion Aggressive salvage resection surgery can be an effective component of a multidisciplinary treatment regimen, even for a postoperative liver metastasis that developed after radical resection of an advanced Klatskin tumour, provided that the metastasis is solid and has not failed local-regional control.

Associated Replacement of Ascending Aorta, Aortic Valve, and Noncoronary Sinus of Valsalva

JOURNAL OF CARDIAC SURGERY, Issue 4 2007
Francesco Santini M.D.
It offers the advantage to secure stable hemostasis in an area where surgical exposure may be difficult to achieve off-pump. For its easy reproducibility, this procedure might contribute to a more radical resection of diseased tissue thus limiting risk of further dilatation, rupture, and need for reoperation. [source]


Elevated serum level and gene polymorphisms of TGF-,1 in gastric cancer

JOURNAL OF CLINICAL LABORATORY ANALYSIS, Issue 3 2008
Xue Li
Abstract Transforming growth factor (TGF)-,1, as a candidate tumor marker, is currently of interest. In this study, serum TGF-,1 levels in gastric cancer (GC) patients and healthy volunteers were measured using enzyme-linked immunosorbent assay (ELISA). In addition, single nucleotide polymorphisms (SNPs) of the TGF-,1 gene at codon 10 and codon 25 were identified by means of amplification refractory mutation system,polymerase chain reaction (ARMS-PCR) and sequence analysis. Our results indicated that serum concentrations of TGF-,1 in GC patients were significantly higher than those in the control, and positively correlated with tumor mass, invasion, metastasis, and clinical stage. The serum TGF-,1 levels of patients recovering from radical resection were markedly lower than those before surgery. Meanwhile, no deoxyribonucleic acid (DNA) sequence variation at codon 25 of the TGF-,1 gene was found and a TGF-,1 gene polymorphism at codon 10 did not show obvious correlations with either TGF-,1 expression or clinicopathological parameters of GC. Our evidence suggested that serum concentration of TGF-,1 might be a novel tumor marker for GC and the polymorphisms of TGF-,1 gene did not play a role as a determinant of serum TGF-,1 concentration or as a genetic risk factor in the gastric carcinogenesis and progression.

Liver transplantation for non,hepatocellular carcinoma malignancy: Indications, limitations, and analysis of the current literature

LIVER TRANSPLANTATION, Issue 8 2010
Eric J. Grossman
Orthotopic liver transplantation (OLT) is currently incorporated into the treatment regimens for specific nonhepatocellular malignancies. For patients suffering from early-stage, unresectable hilar cholangiocarcinoma (CCA), OLT preceded by neoadjuvant radiotherapy has the potential to readily achieve a tumor-free margin, accomplish a radical resection, and treat underlying primary sclerosing cholangitis when present. In highly selected stage I and II patients with CCA, the 5-year survival rate is 80%. As additional data are accrued, OLT with neoadjuvant chemoradiation may become a viable alternative to resection for patients with localized, node-negative hilar CCA. Hepatic involvement from neuroendocrine tumors can be treated with OLT when metastases are unresectable or for palliation of medically uncontrollable symptoms. Five-year survival rates as high as 90% have been reported, and the Ki67 labeling index can be used to predict outcomes after OLT. Hepatic epithelioid hemangioendothelioma is a rare tumor of vascular origin. The data from single-institution series are limited, but compiled reviews have reported 1- and 10-year survival rates of 96% and 72%, respectively. Hepatoblastoma is the most common primary hepatic malignancy in children. There exist subtle differences in the timing of chemotherapy between US and European centers; however, the long-term survival rate after transplantation ranges from 66% to 77%. Fibrolamellar hepatocellular carcinoma is a distinct liver malignancy best treated by surgical resection. However, there is an increasing amount of data supporting OLT when resection is contraindicated. In the treatment of either primary or metastatic hepatic sarcomas, unacceptable survival and recurrence rates currently prohibit the use of OLT. Liver Transpl 16:930-942, 2010. © 2010 AASLD.

Major liver resections for hepatocellular carcinoma on cirrhosis: Early and long-term outcomes

LIVER TRANSPLANTATION, Issue S2 2004
Lorenzo Capussotti
Since the lack of donors, liver resections continue to be the treatment of choice for cirrhotic patients with good liver function and resectable hepatocellular carcinoma (HCC). Moreover, over the past 2 decades, an increasing number of major hepatic resections have been performed. The aim of this study is to evaluate short- and long-term outcomes of 55 cirrhotic patients undergoing major hepatic resection with particular attention to the survival of the patients with gross portal vein invasion or large size tumors. Twenty-two patients (40%) required intra- or post-operative blood transfusion. Medium tumor size was 66.6±29.2 mm; 7 patients had large size (> 10 cm) HCCs. A single node was present in 38 cases (69.1%). There was a gross portal vein tumor thrombus (PVTT) in 13 patients (23.6%). Resection was non-curative in 4 cases. In-hospital mortality and morbidity rates were 5.5% and 30.9%, respectively. The overall and disease-free survival rates were 36.2% and 42.8%, respectively. Overall 5-year survival rates of patients with large size tumors was 17.1%. Ten patients with a gross PVTT had an R0 resection with a 26.6% 5-year survival rate. In conclusion, major hepatic resections for HCC can be performed with low mortality and morbidity rates. HCCs with PVTT or greater than 10 cm in size have very limited options of treatment; the favorable long-term results of our study suggest that they should undergo surgery if a radical resection can be achieved.

Epidemiology and prognosis of ovarian metastases in colorectal cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 11 2010
J. Segelman
Background: National guidelines for prophylactic oophorectomy in women with colorectal cancer are lacking. The aim of this population-based cohort study was to report on the prevalence, incidence and prognosis of ovarian metastases from colorectal cancer, providing information relevant to the discussion of prophylactic oophorectomy. Methods: All 4566 women with colorectal cancer in Stockholm County during 1995,2006 were included and followed until 2008. Prospectively collected data regarding clinical characteristics, treatment and outcome were obtained from the Regional Quality Registry. Results: The prevalence of ovarian metastases at the time of diagnosis of colorectal cancer was 1·1 per cent (34 of 3172) among women with colonic cancer and 0·6 per cent (8 of 1394) among those with rectal cancer (P = 0·105). After radical resection of stage I,III colorectal cancer, metachronous ovarian metastases were found during follow-up in 1·1 per cent (22 of 1971) with colonic cancer and 0·1 per cent (1 of 881) with rectal cancer (P = 0·006). Survival in patients with ovarian metastases was poor. Conclusion: Ovarian metastases from colorectal cancer are uncommon. Copyright © 2010 British Journal of Surgery Society Ltd.

Transanal endoscopic microsurgery is a safe and reliable technique even for complex rectal lesions

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 7 2008
R. J. Darwood
Background: Transanal endoscopic microsurgery (TEM) is a minimally invasive technique for the excision of rectal lesions, with lower morbidity and mortality rates than open surgery. Following advances in laparoscopic colorectal surgery and endoscopic mucosal resection, this study evaluated the safety and efficacy of TEM in the treatment of complex rectal lesions. Methods: All patients were entered into a prospective database. Complex lesions were identified as high (more than 15 cm from anorectal margin), large (maximum dimension over 8 cm), involving two or more rectal quadrants, or recurrent. Results: Seventy-one lesions (13 carcinomas and 58 tubulovillous adenomas) were identified. The median duration of operation was 60 (interquartile range (i.q.r.) 30,80) min, with an estimated median blood loss of 0 (i.q.r. 0,10) ml. Median hospital stay was 2 (i.q.r. 1,3) days. One patient developed postoperative urinary retention and one returned with rectal bleeding that did not require further surgery. Two patients developed rectal strictures after operation that were dilated successfully. There was no recurrence of benign lesions during a median follow-up of 21 (i.q.r. 6·5,35) months. Conclusion: TEM is a safe technique with low associated morbidity, even when used to excise complex rectal lesions. As such it remains the treatment of choice for rectal lesions not requiring primary radical resection. Copyright © 2008 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

High recurrence rate after atypical resection for pancreatic metastases from renal cell carcinoma

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 5 2003
C. Bassi
Background: Pancreatic metastases from renal cell carcinoma are rare but highly resectable. The aim of this study was to review a series of patients with this condition. Methods: The study involved 22 consecutive patients with histologically proven pancreatic metastases from renal cell cancer. Results: Seventeen of the 22 patients had surgery. No patient died but eight of the 17 patients had a postoperative complication. Median follow-up was 33 (range 1,96) months. The 24- and 60-month survival probabilities were 0·84 and 0·53 respectively. Five patients who did not undergo surgery had 24- and 60-month survival probabilities of 0·53 and 0·26 respectively. The difference between the two groups was significant (P = 0·040). Conclusion: Despite the slow development of these secondaries and their well encapsulated morphology, the high rate of recurrence after limited resection suggests that radical resection should be recommended.

HER-2/neu overexpression in patients with radically resected nonsmall cell lung carcinoma

CANCER, Issue 10 2002
Impact on long-term survival
Abstract BACKGROUND Using immunohistochemistry, the authors prospectively investigated the expression of HER-2/neu protein in radically resected specimens of nonsmall cell lung carcinoma (NSCLC) and evaluated its impact on long-term prognosis. METHODS Between January 1991 and February 1992, surgical specimens from 130 consecutive patients who underwent radical resection for NSCLC (60 squamous cell carcinoma, 48 adenocarcinoma cases, and 22 large cell carcinomas) and that were staged (according to the TNM staging system) pathologically as Stage I (41 cases [ 32%]), Stage II (37 cases [28%]), and Stage IIIA (52 cases [40%]) were investigated for the expression of HER-2/neu using an avidin-biotin complex immunohistochemical technique. A semiquantitative four-stage grading system was used (0%, 1,5%, 6,20%, and > 20% positive cells) and an average number of 1500 cells/section was considered. Data were correlated with clinical and pathologic variables. RESULTS Normal bronchial tissue was found to be completely negative for HER-2/ neu expression whereas 21 of the 130 tumor specimens (16%) were positive (range 1,> 20%). HER-2/neu positivity did not appear to differ significantly among pathologic stages and histotypes. Using a predetermined cutoff value of 5% positive cells, 15 tumor specimens (12%) were found to be above this value. The median survival time (85 weeks vs. 179 weeks) and overall survival rate were significantly lower in patients with > 5% HER-2/neu -positive tumors (hazard ratio for the group with > 5% positive cells: 2.94, 95% confidence interval, 1.62,5.34; P < 0.0004). On multivariate analysis, HER-2/ neu and extent of tumor emerged as independent factors for disease-related mortality. CONCLUSIONS In NSCLC, the negative impact of HER-2/neu overexpression on survival was maintained in the long-term follow-up of radically resected patients. HER-2/neu overexpression may be a valuable prognostic factor as well as a potential target for biologic therapies. Cancer 2002;94:2669,74. © 2002 American Cancer Society.

Transanal endoscopic microsurgery in 143 consecutive patients with rectal adenocarcinoma: results from a Danish multicenter study

COLORECTAL DISEASE, Issue 3 2009
G. Baatrup
Abstract Objective, The long-term results are presented on total survival, cancer-specific survival and recurrence in 143 consecutive patients treated with transanal endoscopic microsurgery (TEM) for adenocarcinoma of the rectum. Method, Four Danish centres established in 1995 a database for registration of all TEM procedures. Data were supplemented from pathology reports and death certificates were checked in the Danish patient registry. Data were analysed with multivariance regression and survival analysis. Results, The T stage was as follows: T1 50%, T2 33%, T3 14%, and stage unknown 3%. TEM was performed with curative intent in 43%, for compromise in 52% and for palliation in 5%. Five-year total survival was 66% and 5-year cancer-specific survival 87%. Cancer-specific survival for T1 was 94%. The significant predictors for total survival were age and tumour size. For cancer-specific survival T stage, radical resection, tumour size and recurrence were significant predictors. Eighteen per cent had recurrence and 15% had immediate reoperation. Conclusion, The TEM provides good long-term results for pT1 cancers. In old patients and patients with co-morbidity TEM may provide acceptable long-term results for T2 cancers. Tumours larger than 3 cm should not be treated with TEM for cure. [source]


Colorectal cancer in the young: a 12-year review of patients 30 years or less

COLORECTAL DISEASE, Issue 3 2004
M. H. Kam
Abstract Objectives As the incidence of young colorectal cancer is rising, a review of the characteristics of such malignancy in those under 30 years of age is timely at this stage. Patients and methods Thirty-nine patients (21 M, 18 F) were operated upon over a 12-year period in a single centre. The mean age was 25 years and median follow-up was 20 months. Results Rectal bleeding, change in bowel habit and abdominal pain were the commonest symptoms. Six patients had a positive family history, while four others were diagnosed as index cases of familial adenomatous polyposis. Rectal tumours made up 43% of all colorectal cancers diagnosed. Seventy percent of patients presented at an advanced stage, but curative resection was attempted for 29 patients. Eight underwent palliative resections, 1 had an ileostomy while another underwent a bypass procedure. Eleven patients have died, 14 had no evidence of recurrent disease while 3 were still alive with recurrent disease. Conclusion Age does not affect survival, and early endoscopy is recommended for all with persistent symptoms. Early diagnosis, radical resection and adjuvant therapy still form the cornerstone in management of colorectal cancer in this age group. [source]


International survey on esophageal cancer: part II staging and neoadjuvant therapy

DISEASES OF THE ESOPHAGUS, Issue 3 2009
J. Boone
SUMMARY The outcome of esophagectomy could be improved by optimal diagnostic strategies leading to adequate preoperative patient selection. Neoadjuvant therapy could improve outcome by increasing the number of radical resections and by controlling metastatic disease. The purposes of this study were to gain insight into the current worldwide practice of staging modalities and neoadjuvant therapy in esophageal cancer, and to detect intercontinental differences. Surgeons with particular interest in esophageal surgery, including members of the International Society for Diseases of the Esophagus, the European Society of Esophagology , Group d'Etude Européen des Maladies de l'Oesophage, and the OESO, were invited to participate in an online questionnaire. Questions were asked regarding staging modalities, neoadjuvant therapy, and response evaluation applied in esophageal cancer patients. Of 567 invited surgeons, 269 participated resulting in a response rate of 47%. The responders currently performing esophagectomies (n= 250; 44%) represented 41 countries across the six continents. Esophagogastroscopy with biopsy and computed tomography (CT) scanning were routinely performed by 98% of responders for diagnosing and staging esophageal cancer, while endoscopic ultrasound (EUS) and barium esophagography were routinely applied by 58% and 51%, respectively. Neoadjuvant therapy is routinely administered by 33% and occasionally by 63% of responders. Of the responders that administer identical neoadjuvant regimens to esophageal adenocarcinoma (AC) and squamous cell carcinoma, 54% favor chemoradiotherapy. For AC, chemotherapy is preferred by 31% of the responders that administer neoadjuvant therapy, whereas for squamous cell carcinoma, the majority of responders (38%) prefer chemoradiotherapy. Response to neoadjuvant therapy is predominantly assessed by CT scanning of the chest and abdomen (86%). Barium esophagography, EUS, and combined CT/PET scan are requested for response monitoring in equal frequency (25%). Substantial differences in applied staging modalities and neoadjuvant regimens were detected between surgeons from different continents. In conclusion, currently the most commonly applied diagnostic modalities for staging and restaging esophageal cancer are CT scanning of the chest and abdomen, gastroscopy, barium esophagography and EUS. Neoadjuvant therapy is routinely applied by one third of the responders. Intercontinental differences have been detected in the diagnostic modalities applied in esophageal cancer staging and in the administration of neoadjuvant therapy. The results of this survey provide baseline data for future research and for the development of international guidelines. [source]
