RESUMO

In total, ~25% of familial breast cancer (BC) is attributed to germline mutations of the BRCA1 and BRCA2 genes, while the rest of the cases are included in the BRCAX group. BC is also known to affect men, with a worldwide incidence of 1%. Epigenetic alterations, including DNA methylation, have been rarely studied in male breast cancer (MBC) on a genome-wide level. The aim of the present study was to examine the global DNA methylation profiles of patients with BC to identify differences between familial female breast cancer (FBC) and MBC, and according to BRCA1, BRCA2 or BRCAX mutation status. The genomic DNA of formalin-fixed paraffin-embedded tissues from 17 women and 7 men with BC was subjected to methylated DNA immunoprecipitation and hybridized on human promoter microarrays. The comparison between FBC and MBC revealed 2,846 significant differentially methylated regions corresponding to 2,486 annotated genes. Gene Ontology enrichment analysis revealed molecular function terms, such as the GTPase superfamily genes (particularly the GTPase Rho GAP/GEF and GTPase RAB), and cellular component terms associated with cytoskeletal architecture, such as 'cytoskeletal part', 'keratin filament' and 'intermediate filament'. When only FBC was considered, several cancer-associated pathways were among the most enriched KEGG pathways of differentially methylated genes when the BRCA2 group was compared with the BRCAX or BRCA1+BRCAX groups. The comparison between the BRCA1 and BRCA2+BRCAX groups comprised the molecular function term 'cytoskeletal protein binding'. Finally, the functional annotation of differentially methylated genes between the BRCAX and BRCA1+BRCA2 groups indicated that the most enriched molecular function terms were associated with GTPase activity. In conclusion, to the best of our knowledge, the present study was the first to compare the global DNA methylation profile of familial FBC and MBC. The results may provide useful insights into the epigenomic subtyping of BC and shed light on a possible novel molecular mechanism underlying BC carcinogenesis.

RESUMO

BACKGROUND: This study explores the impact of Hypertermic Intra PEritoneal Chemotherapy (HIPEC) on adrenocortical carcinoma (ACC) management through a safety analysis completed by a preliminary evaluation of survival performances. METHODS: Retrospective chart review of 27 patients submitted to surgical treatment completed by HIPEC for primary (SP, 13 patients) or recurrent (SR, 14 patients, 17 treatments) ACC. Safety was evaluated by means of procedural morbidity and mortality. Survival performances included multiple end points: local/peritoneal disease-free survival (l/pDFS), overall progression-free survival (OPFS), and overall survival (OS). RESULTS: In the SP group, mortality was nil and morbidity was 46% (major 23%). At a median follow-up of 25 months, the median value for all the different survival measures had not been reached. Mortality was also nil in the SR group. However, morbidity was 77% (major 18%). Median l/pDFS and OPFS were 12 ± 4 and 8 ± 2 months, respectively. At a median follow-up of 30 months, median OS had not been reached. CONCLUSION: Surgery and HIPEC is an invasive procedure. Its employment in the surgery for primary setting deserves attention as it may affect oncologic outcomes positively. Its value in the management of recurrences seems less appreciable, albeit it may find its place in the multimodal management of a rare disease for which multiple therapeutic options do not yet exist.

RESUMO

There is no consensus on follow-up after gastric surgery for cancer, nor evidence that it improves outcomes. We investigated the impact of intensity of follow-up, comparing the regimens adopted by two centres, in Italy and in the UK. Patients who underwent surgery for gastric and junctional type-3 adenocarcinoma, between September 2009 and April 2013, at the Surgical Clinic, University of Brescia (Italy), and at the Department of Upper Gastrointestinal Surgery, University College London Hospital (UK), were identified. Patients' demographics, stage, recurrence rates, modality of detection and treatment were recorded. Overall survival and costs were compared between the two protocols. A total of 128 patients were included. Recurrence rates were similar (p = 0.349), with more than 70% diagnosed during regular follow-up appointments in both centres. At univariate and multivariate analysis, stage I and treatment of recurrence were associated with a better survival. Patients treated for recurrence at the Italian centre showed an almost significant better survival (p = 0.052). The intensive Italian surveillance protocol was associated with significant higher costs per year. Follow-up and early detection of recurrence did not affect survival in the analysed series, focused on periods in which chemotherapy was ineffective towards recurrence. However, intensive follow-up allowed a greater number of patients to receive a treatment for recurrence; this might prove useful in the next few years, when more effective chemotherapy combinations are expected to become available. The costs could be reduced by adopting a less intensive surveillance programme.

RESUMO

PURPOSE: To analyze the population submitted to gastric cancer surgery in our Institution in order to find those characteristics which could help in the identification of the elderly high-risk patient. METHODS: In a cohort of 263 patients (>65 y) we selectively investigated the risk factors for medical and surgical complications and postoperative mortality, focusing on the variable "age". All the significant variables were used to find predictors of complications with Clavien-Dindo>2. RESULTS: Age>75 (AUC 0.61; 95% 0.55-0.67, p = 0.003) and ASA score >2 (AUC 0.60; 95% CI 0.54-0.67, p = 0.01) were significantly associated with an increased risk of medical complications. Operative time >330 min (OR 1.00; 95% CI 1.00-1.01; p = 0.0001- AUC 0.62, 95% CI 0.56-0.68, p = 0.01) was the only significant predictor of surgical complications. In-hospital mortality (6/263 patients) was significantly associated with preoperative albumin ≤2.95 g/dl (OR 0.15; 95% CI 0.04-0.93, p = 0.041 - AUC 0.74 95% CI 0.68-0.80; p = 0.003) and additional procedures (OR 7.05; 1.23-40.32, p = 0.03). Stepwise multivariate analysis showed that albumin ≤2.95 g/dl (OR 3.43; 95% CI 1.06-11.13 p = 0.033), ASA>2 (OR 9.51; 95% CI 1.23-72.97; p = 0.042) and additional resections (OR 3.39; 95% CI 1.36-8.45; p = 0.045) were independent risk factors for complications Clavien Dindo >2. CONCLUSIONS: Our work demonstrated that, in our institution, 75 years of age could identify the elderly in gastric surgery as those patients were at higher risk of medical complications. ASA >2, preoperative serum albumin ≤2.95 g/dl and the need of additional procedures could increase the risk of severe postoperative adverse events.

RESUMO

BACKGROUND: Duodenal stump fistula (DSF) is a severe complication of gastrectomy. Although nonsurgical therapy is preferred, surgery is still mandatory in one third of DSF patients. The aim of this article is to analyze the surgical management of DSF and factors related to its outcome. METHODS: We performed a retrospective multicenter study using data from January 1990 to November 2011 in 16 Italian surgery centers. We collected 8,268 elective gastrectomies for malignancies, 7,987 by the laparotomic and 281 by the laparoscopic approach. Two hundred five patients developed a DSF, 75 of whom underwent surgery for DSF. We analyzed mortality and DSF healing time as well as the impact of clinical, oncological, and surgical characteristics. RESULTS: The laparoscopic approach increased the risk of DSF development (odds ratio 5.6, 95% confidence interval 2.7-10.6, P < 0.001). The indication for first DSF surgery was intra-abdominal sepsis; the failure rate was over 30%, associated with the appearance of fistulas of neighboring organs, bleeding, and the need for reoperations. The mortality rate was 28% and was related to the presence of vascular disease (P = 0.04), more than one reoperation (P = 0.05), sepsis (P < 0.001), and renal failure (P < 0.001). Fifty-four patients recovered after a median of 39 days (interquartile range 22-68 days); the need to perform more reoperations (P < 0.01) and the presence of an abdominal abscess (P < 0.01) led to an increase in healing time. CONCLUSIONS: Surgery for DSF has a poor prognosis. Our data will help to identify patients at risk of death, but unfortunately could not establish the best surgical procedure applicable to all cases of DSF.

RESUMO

BACKGROUND: A score predictive of tumor recurrence after radical surgery for non-cardia gastric cancer was previously developed in Italian centers. The aim of this study was to validate the score in a consecutive cohort with prospectively collected follow-up data. STUDY DESIGN: Of 1,178 patients surgically treated between 1998 and 2006, six hundred and thirty-five patients who fulfilled the selection criteria and completed the follow-up program were available for analysis. The score value for each patient was calculated using the formula obtained from a logistic regression model. Discrimination and calibration of the score in the validation group were evaluated and compared with the data of 438 patients in the study group where the score was developed. RESULTS: Most patients in both groups had very low or very high score values. In the validation group, the observed recurrence rates ranged from 5% to 92% in different score strata. The area under the receiver operating characteristic curve was 0.889 (95% CI, 0.864-0.914; p < 0.001), indicating a high discrimination value of the score for recurrence. A good calibration was observed by comparing the predicted risk with the actual risk of recurrence. With a score cut-off value of 50, sensitivity, specificity, and overall accuracy were 74%, 86%, and 81%, respectively. An inverse correlation between the time to recurrence and score level was also estimated (R(2) = 0.119; p < 0.001). CONCLUSIONS: The high predictive value of the score was validated in a consecutive cohort. These results might allow the introduction of the score in clinical practice for Western patients.

RESUMO

PURPOSE: Management of patients with synchronous hepatic metastases as the sole metastatic site at diagnosis of gastric cancer is debated. We studied a cohort of patients admitted to surgical units, investigating prognostic factors of clinical relevance and the results of various therapeutic strategies. METHODS: Retrospective multicentre chart review. We evaluated how survival from surgery was influenced by patient-related, gastric cancer-related, metastasis-related and treatment-related candidate prognostic factors. RESULTS: Forty-four patients received palliative surgery without resection, 98 palliative gastrectomy (in 16 cases associated with R+ hepatectomy), whereas 53 patients received both curative gastrectomy and hepatic resection(s) (R0). Adjuvant chemotherapy was administered to 44 patients. Therapeutic approach was selected on the basis of extension of disease, patient's general conditions and surgeon's attitude. Surgical mortality was 4.6 % and morbidity was 17.4 %. Survival was independently influenced by the factor T of the gastric primary (p = 0.036) and by the degree of hepatic involvement (p = 0.010). T > 2 and H3 liver involvement were associated with worse prognosis with cumulative effect (p = 0.002). Therapeutic approach to the metastases (p = 0.009) and adjuvant chemotherapy (p < 0.001) displayed independent impact upon survival, with benefit for those receiving aggressive multimodal treatment. The 1-, 3-, and 5-year survival rates were 50.4, 14.0, and 9.3 %, respectively, for patients submitted to curative surgery, 16, 8.5, and 4.3 % after palliative gastrectomy, and 6.8, 2.3, and 0 % after palliative surgery without resection. CONCLUSIONS: Our data suggest some clinical criteria that may facilitate selection of candidates to curative surgery, which offers the best survival chances, especially when associated with adjuvant chemotherapy.

RESUMO

PURPOSE: The purpose of the present study was to analyze clinicopathologic features and long-term prognosis of gastric stump cancer (GSC) arising in the remnant stomach 5 years or later after partial gastrectomy for benign disease. METHODS: We reviewed the results of 176 patients resected with curative intent for GSC at 8 Italian centers belonging to the Italian Research Group for Gastric Cancer (GIRCG). The median (range) follow-up time for surviving patients was 71.2 (6-207) months. RESULTS: One hundred forty-six patients were men, the mean age at the time of diagnosis was 69.2 years, and the great majority (167 cases) underwent Billroth II reconstruction. R0 resection was achieved in 158 (90 %) patients, and in 94 (53 %) lymph node dissection was ≥D2. Postoperative mortality and complication rates were 6.2 and 43.2 %, respectively. T1 tumor was diagnosed in 45 (25 %) cases. Lymph node metastases were evident in 86 patients (49 %). Thirteen patients had involvement of the jejunal mesentery nodes (pJN+); five cases were T2-T3 and eight cases were T4. Overall 5-year survival rate was 53.1 %. Five-year survival rates were 68.1, 37.8, and 33.1 % for pT1, pT2-3, and pT4 tumors, respectively (P = 0.001). Five-year survival rate was 56.5 % for node-negative tumors (pN0), 32.3 % for tumors with nodal metastases without involvement of jejunal mesentery nodes (pN+), and 17.1 % for tumors with involvement of jejunal mesentery nodes (pJN+) (P = 0.002). CONCLUSIONS: Our study suggests that an aggressive surgical approach can achieve a satisfactory outcome in GSC.

RESUMO

BACKGROUND: The Italian Research Group for Gastric Cancer supports the practice of follow-up after radical surgery for gastric cancer. METHODS: This multicenter, retrospective study (1998-2009) included patients with T1-4N0-3M0 gastric cancer who had undergone D2 gastrectomy and lymphadenectomy, with at least 15 lymph nodes examined, and who had developed recurrent disease. Timing and site of recurrence were correlated to the actual scheduled follow-up timing and modalities. RESULTS: From eight centers, 814 patients with recurrent cancer and over 1,754 (46.4 %) patients undergoing gastrectomy were investigated (median follow-up 31 months). The most frequent sites of recurrence were local/regional lymph nodes (35.4 %), liver (24.3 %), peritoneum (30.3 %), lung (10.4 %) and intraluminal (7.5 %). Ninety-four percent of the recurrences were diagnosed within 2 years and 98 % within 3 years. Thoracoabdominal computed tomography (CT) scan and (18)F-fluoro-2-deoxy-D-glucose positron emission tomography (18-FDG-PET) detected more than 90 % of recurrences, abdominal ultrasound detected 70 % and tumor markers detected 40 %, while <10 % were identified by physical examination, chest X-ray, and upper gastrointestinal endoscopy. Twenty-six percent of patients with recurrence were treated, but only 3.2 % were treated with potentially radical intent. CONCLUSION: Oncological follow-up after radical surgery for gastric cancer should be focused in the first 3 years, and based mainly on thoracoabdominal CT scan and 18-FDG-PET.

RESUMO

OBJECTIVE: To conduct a retrospective evaluation of the 7th-TNM classification of gastric cancer (GC) on a prospectively collected database. BACKGROUND: The recent TNM introduced relevant changes to GC classification. METHODS: Data regarding 2090 consecutive patients with noncardia GC operated upon between 1991 and 2005 at 5 specialized centers were considered. The application of the new TNM was simulated, and its prognostic value was estimated. RESULTS: Relevant changes in stage distribution between 6th and 7th TNM were observed, mainly regarding the shift of a large proportion of cases from stages IB to IIA and from IIIA and IV to stages IIIB and IIIC. Cancer-related 10-year survival probability was 53% ± 1%. Different survival rates between new T (T2 vs. T3, P < 0.001) and N categories (N1 vs. N2, P < 0.001) were observed. Survival rate of N3a subgroup (7-15 involved lymph nodes) was significantly better than N3b (>15 involved lymph nodes; P < 0.001). Stages IB and IIA of the 7th TNM showed similar prognosis, whereas significant differences were observed among all other subgroups. The analysis of TNM categories within 7th TNM stages revealed nonhomogeneous survival rates in stages IIB, IIIB, and IV. CONCLUSIONS: The 7th AJCC/UICC TNM classification of noncardia GC identifies subgroups of patients with different prognosis. Stage distribution and stage-related survival changed notably from the 6th edition. Some improvements may be suggested from our data, with special reference to a higher prognostic weight of N status and the separation of N3a and N3b categories for stage grouping.

RESUMO

OBJECTIVE: Hepatocellular carcinoma is often diagnosed in elderly people. METHODS: One hundred and seventy-five patients older than 70 years were operated on for hepatocellular carcinoma (Group 1). The results were compared with 276 resected patients younger than 70 (Group 2) and to 108 aged patients with chronic liver disease without hepatocellular carcinoma (Group 3). RESULTS: Hepatocellular carcinoma in the elderly is more frequently associated with hepatitis C virus, less frequently capsulated and less frequently diagnosed by screening programs than in young patients. After resection, no difference was noted in post-operative complications and in mortality rates (3.2%); major hepatic resection in cirrhosis carried a high risk of death (22%). Five years survival was 42%, comparable with the young surgical patients but significantly lower than the medical patients in Group 3. Recurrence of hepatocellular carcinoma was the main reason of death, but it was suitable for a radical treatment in 37.6% of cases, including surgery, with a mean survival of 31 months. CONCLUSIONS: Liver resection is a valid option for the treatment of hepatocellular carcinoma in the elderly; major resections in cirrhotic old patients must be reserved for selected cases. Recurrence may be suitable of a radical approach, including surgery.

RESUMO

BACKGROUND: The presence of lymph node metastasis is one of the most important prognostic factors in patients with gastric carcinoma. Node-negative patients have a better outcome, nevertheless a subgroup of them experience disease recurrence. AIM: To analyze the clinicopathological characteristics of lymph node-negative advanced gastric carcinoma patients submitted to gastrectomy and D2 lymphadenectomy with a retrieved number of nodes greater than 15, after an actual follow-up of almost 5 years, and to evaluate outcome indicators. STUDY DESIGN: The records of 301 patients who underwent curative gastrectomy for gastric carcinoma and were adequately staged as N0 between 1992 and 2002 were retrospectively analyzed from the prospectively collected database of 7 centers participating to the Italian Research Group for Gastric Cancer. RESULTS: Disease-specific and disease-free survival after 3, 5, and 10 years were 90.4%, 86.1%, 75.9%, and 72.1%, 57.3%, 57.3%, respectively. Mortality was 1.7%. The factors associated with a better disease-free survival at univariate analysis were age <60, T2 tumors, distal location, intestinal histotype, and number of retrieved nodes >25; depth of infiltration and histotype were the only 2 independent predictors of 5-year recurrence-free survival at multivariate analysis. CONCLUSION: These parameters must be considered to stratify node-negative gastric cancer patients for an adjuvant treatment and follow-up scheduling. Survival was similar to that previously reported by Eastern Centers. Lymphadenectomy is suggested to be effective, and retrieval of more than 25 nodes may be warranted.

RESUMO

BACKGROUND: Duodenal fistula (DF) after gastrectomy continues to be a life-threatening problem. We performed a retrospective multicenter study analyzing the characteristics of DF after elective gastrectomy for malignant disease. METHODS: Three thousand seven hundred eighty-five patients who had undergone gastrectomy with duodenal stump in 11 Italian surgical units were analyzed. RESULTS: Sixty-eight DFs occurred, with a median frequency of 1.6% and a mortality rate of 16%. Complications were mainly septic but fistulas or bleeding of surrounding organs accounted for about 30%. Reoperation was performed in 40% of patients. We observed a correlation between mortality and age (hazard ratio 1.09; 95% CI 1.00-1.20) and serum albumin (hazard ratio 0.90; 95% CI 0.83-0.99). The appearance of further complications was associated with reoperation (P < 0.001) and death (P = 0.054), while the preservation of oral feeding was related to DF healing (P < 0.001). CONCLUSIONS: This paper represents the largest series ever published on DF and shows that its features have changed in the last 20 years. DF alone no longer leads to death and some complications observed in the past have disappeared, while new ones are emerging. Nowadays, medical therapy is preferred and surgery is indicated only in cases of abdominal sepsis or bleeding.

RESUMO

BACKGROUND AND OBJECTIVES: The recurrence of hepatocellular carcinoma (HCC) after percutaneous ablation is poorly evaluated. METHODS: Thirty-six cases of recurrence after percutaneous ablation (PA) (Group 1) are compared to those after surgery, treated with re-resection (26 patients, Group 2) and PA (31 patients, Group 3). RESULTS: Recurrence was usually local after PA and distant after resection. Compared to Groups 2 and 3, local recurrences after PA were larger (4.2 vs. 2.3 cm) and more often invasive (43% vs. 10%). No different clinical/pathological aspects were noted in distant recurrences among the groups. After treatment the survival rate (1, 2, 3 and 5 years) was no different between the groups; in an intention-to-treat analysis of survival for local recurrences, survival was significantly lower in Group 1 (78%, 78%, 67% and 28%) than in Groups 2 and 3 (100%, 88%, 75% and 45%) (P < 0.05). CONCLUSIONS: PA and surgery can be sequentially employed for HCC. The type of primary treatment does not influence the features of distant liver recurrence, while local recurrence after PA often requires more extensive liver resection.

RESUMO

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) is an unusual tumour. METHODS: The clinicopathological data of 67 patients with ICC and combined hepatocellular-cholangiocarcinoma (HCC-ICC) are presented. RESULTS: HCV-HBV infection was present in 37.3% and chronic liver disease in 38.7% of cases, a rate higher than in the normal population; in these patients the cancer was small, often asymptomatic and of combined type. Liver resection was performed in 51 patients; at 1, 3 and 5 years, overall survival was 87.9%, 59.0%, and disease-free survival was 47.7% and 78.8%, 51.4%, and 46.7%, respectively. The better results were in the group of cirrhotic patients in whom ICC was diagnosed by a screening program for HCC (5-year survival 76.6%). Nodal metastasis showed negative prognostic value for both overall and disease-free survival; in N+ patients mean survival was 14.7 months after liver resection and lymph node dissection. CONCLUSION: Viral infection and cirrhosis may be considered risk conditions for ICC and combined HCC-ICC; in resected patients survival was good. Nodal metastases must not be considered a contraindication for liver resection.

RESUMO

PURPOSE: To investigate whether the ratio between metastatic and examined lymph nodes (N ratio) is a better prognostic factor as compared with traditional staging systems in patients with gastric cancer regardless of the extension of lymph node dissection. PATIENTS & METHODS: We retrospectively reviewed the data of 1853 patients who underwent radical resection for gastric carcinoma at 6 Italian centers. Patients with >15 (group 1, n = 1421) and those with 25%) were determined by the best cut-off approach. RESULTS: After a median follow-up of 45.5 months (range, 4-182 months), the 5-year overall survival of N0, N1, and N2 patients of group 1 versus group 2 was 83.4% versus 74.2% (P = 0.0026), 54.3% versus 44.3% (P = 0.018), and 32.7% versus 14.7% (P = 0.004), respectively, suggesting that a low number of excised lymph nodes can lead to the understaging of patients. N ratio identified subsets of patients with significantly different survival rates within N1 and N2 stages in both groups. At multivariate analysis, the N ratio (but not N stage) was retained as an independent prognostic factor both in group 1 and group 2 (HR for N ratio 1, N ratio 2, and N ratio 3 = 1.67, 2.96, and 6.59, and 1.56, 2.68, and 4.28, respectively). In our series, the implementation of N ratio led to the identification of subgroups of patients prognostically more homogeneous than those classified by the TNM system. CONCLUSION: N ratio is a simple and reproducible prognostic tool that can stratify patients with gastric cancer also in case of limited lymph node dissection. These data may represent the rational for improving the prognostic power of current UICC TNM staging system and ultimately the selection of patients who may most benefit from adjuvant treatments.

RESUMO

OBJECTIVE: To evaluate the predictive factors, the therapy, and the prognosis of intrahepatic recurrence (IR) after surgery for hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA: The predictive factors of IR are debated. To class the recurrence according to the modality of presentation may help to find a correlation and to select the right therapy for the recurrence. METHODS: A total of 213 patients were evaluated. Risk factors for recurrence were related to time (<2 years and >2 years) and type of presentation (marginal, nodular, and diffuse). Prognosis and therapy for the recurrence were studied in each group of patients. RESULTS: IR was observed in 143 patients; 109 were early (group 1) and 34 late recurrences (group 2). Cirrhosis, chronic active hepatitis (CAH) and HCV positivity were independently related to the risk of recurrence with a cumulative effect (92.5% of recurrences in patients with 3 prognostic factors). For group 1, the neoplastic vascular infiltration together with cirrhosis, HCV positivity, CAH, and transaminases were significant; all the 11 patients with 5 negative prognostic factors showed an early recurrence. On the contrary, only cirrhosis was related to a late recurrence. Survival rate was significantly better in late than in early recurrence (61.9%, 27.1% and 25.7%, 4.5% at 3-5 years); a curative procedure was performed in 67.6% in group 1 and 29.3% in group 2. After a radical treatment of IR, the survival was comparable with the group of patients without recurrence. CONCLUSIONS: Early and late recurrences are linked to different predictive factors. The modality of presentation of the recurrence together with the feasibility of a radical treatment are the best determinants for the prognosis.

RESUMO

BACKGROUND AND OBJECTIVES: The incidence of gastric cancer is increasing in the elderly. The aim of this study is to evaluate the impact of advanced age (> or =80 years) on morbidity, mortality and late outcome after curative surgery for gastric cancer. METHODS: The cases of 30 octogenarians (Group A) with gastric cancer who underwent surgical treatment in our Institution from 1990 to 2003 were reviewed and compared to a simultaneous group of 228 younger patients (Group B). RESULTS: The rate of resective and curative procedures was not different in the two groups, although the American Society of Anaesthesiologists (ASA) risk was significantly higher in the elderly (P < 0.001) and the lymphatic dissection was less extended in group A. In the two groups, the curability was directly correlated to the cancer stage, but not affected by the ASA risk. The postoperative morbidity and mortality rates were similar in the two groups and were not related to the ASA risk. Considering the mortality for gastric cancer alone, the two groups showed a similar survival rate, only correlated to the cancer stage. CONCLUSIONS: In the elderly, an oncologically correct surgical procedure can safely be prosecuted with satisfactory immediate and late results.

RESUMO

Occlusive atherosclerotic disease of the celiac artery may be diagnosed late during pancreatic resection, inducing a sudden ischemic threat to the liver, stomach, pancreas, and new anastomoses. Failure to identify and correct the insufficient supramesocolic flow can result in serious morbidity. We report the case of a 64-year-old man in whom sudden and unexpected visceral ischemia occurred while Whipple's procedure was being performed to resect a cephalopancreatic mass. We diagnosed occlusion of the celiac trunk and achieved celiac revascularization by performing an end-to-side transposition of the celiac artery onto the superior mesenteric artery, which had been dissected during the lymphadenectomy. We describe this technique as an alternative treatment for acute supramesocolic ischemia caused by celiac axis occlusion. It is important that surgeons performing pancreatic surgery are aware of the possibility of this complication because the test occlusion of the gastroduodenal artery, which must always precede its ligation, can be negative.

RESUMO

Radiofrequency ablation is considered safe for inoperable liver neoplasms; with small lesions the rate of success is very high, the local recurrence is marginal and generally suitable for a retreatment. We have little information about the possibility of rapid regrowth of the tumor after a response judged as complete. We present four patients, affected by primary (3 patients) and metastatic (1 patient) uninodular cancer. All the lesions were small, superficial and well suited for surgery, but were treated by radiofrequency ablation elsewhere. The early instrumental evaluations stated a complete result in all the patients. Cancer regrowth was diagnosed at 3, 4, 6 and 12 months after radiofrequency ablation, always starting from the treated lesion. In case 1 the whole right lobe was involved together with a controlateral multinodular recurrence; cases 2 and 3 presented an extensive liver and parietal wall involvement; while in the fourth patient a diffuse biliary colonization was observed. Only 1 patient was suitable for surgery; the others died 6, 2 and 4 months, respectively, after recurrence. Recurrence after radiofrequency ablation may show an aggressive evolution precluding any possibility of cure. Radiofrequency ablation must not be considered a suitable alternative to surgery in patients with a low surgical risk.
