- Abstract
Background: Nodular regenerative hyperplasia (NRH) is a severe form of chemotherapy-related liver injury (CALI) that may worsen the short-term outcome of liver resection (LR) for colorectal metastases (CRLM). The present study aimed to clarify the incidence, risk factors, preoperative assessment, and clinical impact of NRH. Methods: Overall, 406 patients undergoing 478 LRs for CRLM after chemotherapy between 2000 and 2012 were studied. All resection specimens were reviewed. After Gomori staining, NRH was graded according to the Wanless score. Results: NRH was diagnosed in 87 (18.2 %) patients, grades 2-3 in 14 (2.9 %) patients. At multivariate analysis, the prevalence of NRH was increased after oxaliplatin administration (21.4 vs. 8.4 %; p = 0.003), and reduced by the addition of bevacizumab (11.7 vs. 19.8 %; p = 0.020). Two parameters predicted the presence of NRH: the APRI score (AST to platelet ratio index: 25.5 % if >0.36 vs. 9.8 % if ≤0.36; p = 0.004), and the platelet count (63.6 % if <100 × 10/mm vs. 25.3 % if 100-200 × 10/mm vs. 11.9 % if >200 × 10/mm; p = 0.032). Ninety-day mortality and liver failure rates were 0.6 and 3.6 %. NRH was an independent predictor of postoperative liver failure (9.2 % if present vs. 2.3 % if not present; p = 0.021). In patients with grades 2-3 NRH, the rate of liver failure was 14.3 %, 25.0 % after major hepatectomy. No other forms of CALI impacted short-term outcomes. Conclusions: NRH was the most relevant form of CALI, increasing the risk of postoperative liver failure. Oxaliplatin increased the incidence of NRH, while bevacizumab decreased it. The APRI score and platelet count were useful tools for predicting NRH. [ABSTRACT FROM AUTHOR]

Background: Intraoperative liver ultrasound has an established role in liver surgery to complete staging and to guide resection. The same performances should be expected by laparoscopic ultrasound (LUS). Methods: LUS is first performed to identify relationships between tumor and vasculo-biliary pedicles. The planes where the main vascular structures run are marked on the liver surface. Parenchymal transection is performed and each vessel recognized during LUS exploration is divided. Results: From 01/2009 to 10/2013, in 61 out of 742 liver resections (8.2 %), a laparoscopic approach was attempted. The conversion rate was 9.8 % (six patients). No conversion was related to bleeding or intraoperative complications. The remnant 55 patients were affected by benign lesions in 11 cases and malignant tumors in 44. The resections included 3 left hepatectomies, 14 bisegmentectomies Sg2-3, 5 segmentectomies, and 38 wedge resections. Associated procedures were performed in eight patients (14.5 %), including four colorectal resections. Median duration of surgery was 150 min (60-345 min). Median operative blood loss was 100 mL (0-500 mL). Median size of resected tumor was 2.5 cm (0.9-8 cm). Median surgical margin in oncological resections was 7 mm (0-50 mm). Postoperative complications occurred in four patients (7.2 %), all grade 2 according to Dindo classification. No liver-related morbidity occurred. Median length of hospital stay was 5 days (3-9 days). Conclusions: Ultrasound-guided liver resections can be performed by laparoscopic approach with the same accuracy than open surgery.

- Abstract
Background: Lymph node (LN) status is one of the strongest prognostic factors after gallbladder cancer (GBC) resection. The adequate extension of LN dissection and the stratification of the prognosis in N+ patients have been debated. The present study aims to clarify these issues. Methods: A total of 112 consecutive patients who underwent operations for GBC with LN dissection were analyzed. Twenty-five patients (22.3 %) had D1 dissection (hepatic pedicle), and 87 (77.7 %) had D2 dissection (hepatic pedicle, celiac and retro-pancreatic area). The LN ratio (LNR) was computed as follows: number of metastatic LNs/number of retrieved LNs. Results: The median number of retrieved LNs was 7 (1-35). Fifty-nine patients (52.7 %) had LN metastases (22 N2). D2 dissection allowed the retrieval of more LNs (8 vs. 3, p = 0.0007), with similar short-term outcomes. Common bile duct (CBD) resection ( n = 41) did not increase the number of retrieved LNs. In five patients, D2 dissection identified skip LN metastases that otherwise would have been missed. LN metastases negatively impacted survival (5-years survival 57.2 % if N0 vs. 12.4 % if N+, p < 0.0001), but N1 and N2 patients had similar survival rates. The number of LN+ (1-3 vs. ≥4) did not impact prognosis. An LNR = 0.15 stratified the prognosis of N+ patients: 5-years survival 32.7 % if LNR ≤ 0.15 vs. 10.3 % if LNR > 0.15 (multivariate analysis p = 0.007). Conclusions: A D2 LN dissection is recommended in all patients, because it allows for better staging. CBD resection does not improve LN dissection. An LNR = 0.15, not the site of metastatic LNs, stratified the prognoses of N+ patients. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The role of extended resections in the management of advanced pancreatic neuroendocrine tumors (PNETs) is not well defined. Methods: Between 1995 and 2012, 134 patients with PNET underwent isolated (isoPNET group: 91 patients) or extended pancreatic resection (synchronous liver metastases and/or adjacent organs) (advPNET group: 43 patients). Results: The associated resections included 27 hepatectomies, 9 vascular resections, 12 colectomies, 10 gastrectomies, 4 nephrectomies, 4 adrenalectomies, and 3 duodenojejunal resections. R0 was achieved in 41 patients (95 %) in the advPNET. The rates of T3-T4 (73 vs 16 %; p < .0001) and N+ (35 vs 13 %; p = .007) were higher in the advPNET group. Mortality (5 vs 2 %) and major morbidity (21 vs 19 %) rates were similar between the 2 groups. The 5-year overall survival (OS) of the series was 87 % in the isoPNET group and 66 % in the advPNET group ( p = .006). Only patients with both locally advanced disease and liver metastases showed worse survival ( p = .0003). The advPNET group developed recurrence earlier [disease-free survival (DFS) at 5 years: 26 vs 81 %; p < .001]. In univariate analysis, negative prognostic factors of survival were: poor degree of differentiation ( p < .001), liver metastasis ( p = .011), NE carcinoma ( p < .001), and resection of adjacent organs ( p = .013). The multivariate analysis did not highlight any factor that influenced OS. In multivariate analysis independent DFS factors were a poor degree of differentiation ( p = .03) and the European Neuroendocrine Tumor Society stage ( p = .01). Conclusions: An aggressive surgical approach for locally advanced or metastatic tumors is safe and offers long-term survival. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: The aims of this study were to assess the risk of early recurrence after liver resection for colorectal metastases (CRLM) and its prognostic value; identify early recurrence predictive factors; clarify the effect of perioperative chemotherapy on its occurrence; and elucidate the best early recurrence management. Methods: Patients of the LiverMetSurvey registry who underwent complete liver resection (R0/R1) between 1998 and 2009 were reviewed. Early recurrence was defined as any recurrence that occurred within 6 months after resection. Results: A total of 6,025 patients were included; 2,734 (45.4 %) had recurrence, including 639 (10.6 %) early recurrences. Early recurrence was mainly hepatic (59.5 vs. 54.4 % for late recurrences; p = 0.023). Independent risk factors of early recurrence were: T3-4 primary tumor ( p = 0.0002); synchronous CRLM ( p = 0.0001); >3 CRLM ( p < 0.0001); 0-mm margin liver resection ( p = 0.003); and associated intraoperative radiofrequency ablation ( p = 0.0005). Response to preoperative chemotherapy (complete/partial) and administration of adjuvant chemotherapy reduced early recurrence risk ( p = 0.003 and p < 0.0001, respectively). Intraoperative ultrasonography reduced hepatic early recurrence rate ( p = 0.025). Early recurrence negatively affected prognosis: 5-year survival 26.9 versus 49.4 % for the late recurrence group ( p < 0.0001, median follow-up 34.4 months). Overall, 234 (36.6 %) patients with early recurrence underwent re-resection. These patients had survival rates higher than non-re-resected patients (5-year survival 47.2 vs. 8.9 %; p < 0.0001) and similar to re-resected patients for late recurrence (48.7 %). Chemotherapy before early recurrence resection improved later survival (5-year survival 61.5 vs. 43.7 %; p = 0.028). Conclusions: Early recurrence risk is enhanced for extensive disease after poor preoperative disease control and inadequate surgical treatment, but is reduced after adjuvant chemotherapy. Although early recurrence negatively affects prognosis, re-resection may restore better survival. Chemotherapy before early recurrence resection is advocated. [ABSTRACT FROM AUTHOR]

Objectives: To compare the diagnostic accuracy and sensitivity of Gd-EOB-DTPA MRI and diffusion-weighted (DWI) imaging alone and in combination for detecting colorectal liver metastases in patients who had undergone preoperative chemotherapy. Methods: Thirty-two consecutive patients with a total of 166 liver lesions were retrospectively enrolled. Of the lesions, 144 (86.8 %) were metastatic at pathology. Three image sets (1, Gd-EOB-DTPA; 2, DWI; 3, combined Gd-EOB-DTPA and DWI) were independently reviewed by two observers. Statistical analysis was performed on a per-lesion basis. Results: Evaluation of image set 1 correctly identified 127/166 lesions (accuracy 76.5 %; 95 % CI 69.3-82.7) and 106/144 metastases (sensitivity 73.6 %, 95 % CI 65.6-80.6). Evaluation of image set 2 correctly identified 108/166 (accuracy 65.1 %, 95 % CI 57.3-72.3) and 87/144 metastases (sensitivity of 60.4 %, 95 % CI 51.9-68.5). Evaluation of image set 3 correctly identified 148/166 (accuracy 89.2 %, 95 % CI 83.4-93.4) and 131/144 metastases (sensitivity 91 %, 95 % CI 85.1-95.1). Differences were statistically significant ( P < 0.001). Notably, similar results were obtained analysing only small lesions (<1 cm). Conclusions: The combination of DWI with Gd-EOB-DTPA-enhanced MRI imaging significantly increases the diagnostic accuracy and sensitivity in patients with colorectal liver metastases treated with preoperative chemotherapy, and it is particularly effective in the detection of small lesions. Key Points: • Accurate detection of colorectal liver metastases is essential to determine resectability. • Almost 80 % of patients are candidates for neoadjuvant chemotherapic treatment at diagnosis. After chemotherapy, metastases usually decrease, and drug-induced liver steatosis may be present. • The sensitivity of imaging is significantly inferior to that in chemotherapy-naïve patients. • DWI combined with Gd-EOB-DTPA increases sensitivity in detecting small metastases after chemotherapy.

- Abstract
Background: Management of patients with synchronous colorectal liver metastases (SCRLM) should be individually tailored. This study compares patients managed by hepatobiliary centers from diagnosis with those referred for liver resection (LR). Methods: Between 1998 and 2010, a total of 284 patients with SCRLM underwent resection; 106 resectable patients (1-3 unilobar metastases, diameter <100 mm, liver-only disease) were divided into two groups: 66 managed from diagnosis (group A) and 40 referred for LR (group B). Results: Group A contained a greater proportion of multiple metastases (55.0 vs. 34.8 %, P = 0.042). Group B always received colorectal surgery as up-front treatment (vs. 18.2 %, P < 0.0001). In group B, chemotherapy before LR was more common (72.5 vs. 33.3 %, P = 0.0001) and lasted longer ( P = 0.010). More patients in group B exhibited disease progression before LR (17.5 vs. 3.0 %, P = 0.025). Group A underwent fewer surgical procedures (80.3 % simultaneous resection vs. 0 %, P < 0.00001), with similar short-term outcomes. After a median follow-up of 42.0 months, group A exhibited higher 5 year disease-free survival (DFS, 64.8 vs. 30.8 %, P = 0.005) and fewer extrahepatic recurrences (21.5 vs. 47.5 %, P = 0.005). The late-referral group (>6 months, n = 24) had shorter median overall survival (OS) and DFS than group A (49.1 and 25.3 months vs. not achieved and not achieved, P < 0.05). The early-referral group exhibited OS and DFS similar to group A. Multivariate analysis confirmed late referral as a negative predictive factor of OS and DFS. Conclusions: Monocentric management of SCRLM in hepatobiliary centers is associated with shorter preoperative chemotherapy, better disease control, fewer surgical procedures (simultaneous resection), and, compared with late-referred patients, better survival.

Background and Purpose: There is still debate about the practicality of performing laparoscopic colectomy instead of open colectomy for patients with curable cancer, although laparoscopic surgery is now being performed even for patients with advanced colon cancer. We compared the long-term results of laparoscopic versus open colectomy for TNM stage III carcinoma of the colon in a large series of patients followed up for at least 3 years. Methods: The subjects of this prospective non-randomized multicentric study were 290 consecutive patients, who underwent open surgery (OS group; n = 164) or laparoscopic surgery (LS group; n = 126) between 1994 and 2005, at one of the four surgical centers. The same surgical techniques were used for the laparoscopic and open approaches to right and left colectomy. The distribution of TNM substages (III A, III B, IIIC) as well as the grading of carcinomas (G1, G2, G3) were similar in each arm of the study. The median follow-up periods were 76.9 and 58.0 months after OS and LS, respectively. Results: There were 10 (6.1 %) versus 9 (7.1 %) deaths unrelated to cancer, 15 (9.1 %) versus 5 (4 %) cases of local recurrence, 7 (4.2 %) versus 5 (4 %) cases of peritoneal carcinosis, and 37 (22.5 %) versus 14 (11.1 %) cases of metastases in the OS and LS groups, respectively. There was also one case of port-site recurrence after LS (0.8 %). The OS group had a significantly higher probability of local recurrence and metastases ( p < 0.001) with a significant higher probability of cancer-related death ( p = 0.001) than the LS group. Conclusions: These findings support that LS is safe and effective for advanced carcinoma of the colon. Although the LS group in this study had a significantly better long-term outcome than the OS group, further investigations are needed to draw a definitive conclusion. [ABSTRACT FROM AUTHOR]

- Abstract
Purpose: Tumor progression while receiving neoadjuvant chemotherapy (PD) has been associated with poor outcome and is commonly considered a contraindication to liver resection (LR). This study aims to clarify in a large multicenter setting whether PD is always a contraindication to LR. Methods: Data from the LiverMetSurvey international registry were analyzed. Patients undergoing LR for colorectal metastases without extrahepatic disease after neoadjuvant chemotherapy between 1990 and 2009 were reviewed. Results: Among 2143 patients, PD occurred in 176 (8.2 %). Risk of progression was increased after 5-FU or irinotecan (22.7 % vs. 6.8 % after other regimens, p < 0.0001; 14.9 % vs. 7.2 %, p < 0.0001), while it was reduced after oxaliplatin (5.6 % vs. 12.0 %, p < 0.0001) and still diminished among patients receiving targeted therapies (2.6 %). PD was an independent prognostic factor of survival at multivariate analysis (35 % vs. 49 %, p = 0.0006). In the PD group, 3 independent prognostic factors were identified: carcinoembryonic antigen (CEA) ≥200 ng/mL ( p = 0.003), >3 metastases ( p = 0.028), and tumor diameter ≥50 mm ( p = 0.002). A survival predictive model showed that patients without any risk factors had 5-year survival rates of 53.3 %; good survival results were still observed if metastases were >3 or ≥50 mm (29.9 and 19.1 %, respectively). On the contrary, survival was less than 10 % at 3 years in the presence of >1 prognostic factor or CEA of ≥200 ng/mL. Conclusions: PD is a negative prognostic factor, but it is not an absolute contraindication to LR. Patients with PD could be scheduled for LR except for those with >3 metastases and ≥50 mm, or CEA ≥200 ng/mL in whom further chemotherapy is recommended. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Liver resection (LR) is the only potentially curative treatment of colorectal liver metastases (CRLM). Its outcome over the past 2 decades was studied using actual 5-year survival rates. Methods: Data of 393 consecutive patients who underwent LR for CRLM at Mauriziano Umberto I (Turin) until June 2005 were analyzed. Excluding R2 resections ( n = 4) or incomplete 5-year follow-up ( n = 13), 376 patients were divided according to LR date into groups A (before 1995: 90 patients), B (1995-2000: 94 patients), C (2001-2005: 192). Results: Group C presented increased multiple and bilobar metastases compared with combined group A and B (C vs AB: 54.7% vs 40.2%, P = 0.005; 28.1% vs 19.0%, P = 0.038, respectively), decreased metastases diameter (C vs AB: 32 vs 40 mm, P = 0.0001). The 5-year overall survival, calculated excluding 4 operative mortalities (group AB), increased over the years (A, 20.5%; B, 32.6%; C, 46.4%; P < 0.0001). Early recurrences (1 year) were not decreased, extrahepatic recurrences even increased (C vs AB: 17.2% vs 8.6%, P = 0.015). Recurrence-free 5-year survival improved (C vs AB: 23.4% vs 13.9%, P = 0.019) linked to decreased liver recurrences (C vs AB: 26.8% vs 37.4%, P = 0.023). Resection rate (59% overall for liver recurrence) increased along with 5-year survival after recurrence (A, 4.0%; B, 14.2%; C, 21.4%; P < 0.0001). Survival improvement was confirmed for multiple ( P = 0.003) and synchronous metastases ( P = 0.008), N+ tumors ( P = 0.005), and in patients without chemotherapy ( P = 0.001). Conclusions: Long-term outcome of LR for CRLM improved over 20 years, even in patients with negative prognostic factors, linked to hepatic recurrences reduction and increased survival after recurrence.

- Abstract
Background: The aim of the present study is to examine the effect of systemic chemotherapy after the 1st-stage hepatectomy (CT×2) on the progression of disease and dropout rates. A major pitfall of the 2-stage hepatectomy procedure is a high dropout rate after the 1st-stage hepatectomy due to progression of disease (PD). Routine use of CT×2 has been advocated. Methods: A total of 47 patients with multiple, bilateral unresectable liver metastases were selected for a 2-stage hepatectomy procedure (±portal vein occlusion). Results: Of the total, 37 patients (78.7%) underwent systemic chemotherapy before the 1st-stage hepatectomy (CT×1) and 25 patients (53.2%) underwent CT×2; PD was significantly more common during CT×2 than during CT×1 ( P = .002). Of the 47 patients planned for the 2nd-stage hepatectomy, 36 (76.6%) completed the procedure. Of these 47 patients, 25 (53.2%) showed PD after the 1st-stage hepatectomy, 12 in the CT×2 group and 13 in the no-CT×2 group; administration of CT×2 did not significantly affect the PD rate ( P = .561). The overall dropout rate was 23.4% ( n = 11 patients): 16% in the CT×2 group vs. 31.8% in the no-CT×2 group ( P = .303). Conclusions: The routine use of chemotherapy between the 1st- and 2nd-stage hepatectomy does not guarantee lower PD and dropout rates. [ABSTRACT FROM AUTHOR]

- Abstract
Recent advances in patient selection and surgical technique have resulted in low mortality and morbidity rates after liver resections. The aim of this study was to evaluate the operative risks of liver trisectionectomies in comparison with major resections. The data prospectively collected of patients who underwent trisectionectomies (TR Group, n = 54) and major hepatectomies (MH Group, n = 175) without biliary reconstruction were compared. Besides, the early results of patients who underwent right trisectionectomies (RTR Group, n = 36) and left trisectionectomies (LTR Group, n = 18) were compared. There was no significant difference in patient characteristics of MH and TR groups excluded for a high portal vein embolization (PVE) in TR group. Mortality (1% in MH group and 3.7% in TR group, p = 0.206) and overall morbidity rates (39% in MH group and 48% in TR group, p = 0.225) were similar between two groups. A higher proportion of patients in TR group developed liver failure ( p = 0.024) and required blood transfusion (30 vs. 11%, p < 0.001). The median hospital stay after trisectionectomies was higher in TR group than MH group ( p = 0.053). There was no significant difference in patient characteristics of LTR and RTR groups excluded for lymphadenectomy which was higher in LTR group ( p = 0.008) and PVE rate higher in RTR group ( p = 0.01). The overall morbidity (44 vs. 55%) and mortality (2.7 vs. 5.5%) were comparable between two groups. A higher proportion of patients in RTR group required blood transfusion (39 vs. 11%, p = 0.032). At multivariate analysis, age was the only positive predictor for morbidity after trisectionectomies ( p = 0.010). Trisectionectomies can be performed safely. Left trisectionectomies are as safe as right trisectionectomies. The accurate preoperative selection is necessary to reduce operative risks. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Management of neuroendocrine tumor liver metastasis (NELM) remains controversial, with some advocating an aggressive surgical approach while others have adopted a more conservative strategy. We sought to define the efficacy of the surgical management of NELM in a large multicenter international cohort of patients. Methods: We identified 339 patients who underwent surgical management for NELM from 1985 to 2009 from an international database of eight major hepatobiliary centers. Relevant clinicopathologic data were assessed using Kaplan-Meier and Cox regression models. Results: Most patients had a pancreatic (40%) or small bowel (25%) neuroendocrine tumor (NET) primary. The majority of patients (60%) had bilateral liver disease. At surgery, 78% of patients underwent hepatic resection, 3% ablation alone, and 19% resection + ablation. Major hepatectomy was performed in 45% of patients, and 14% underwent a second liver operation. Carcinoid was the most common NET histological subtype (53%). Median survival was 125 months, with overall 5- and 10-year survival of 74%, and 51%, respectively. Disease recurred in 94% of patients at 5 years. Patients with hormonally functional NET who had R0/R1 resection benefited the most from surgery ( P = 0.01). On multivariate analyses, synchronous disease [hazard ratio (HR) = 1.9], nonfunctional NET hormonal status (HR = 2.0), and extrahepatic disease (HR = 3.0) remained predictive of worse survival (all P < 0.05). Conclusions: Liver-directed surgery for NELM is associated with prolonged survival; however, the majority of patients will develop recurrent disease. Patients with hormonally functional hepatic metastasis without prior extrahepatic or synchronous disease derive the greatest survival benefit from surgical management. [ABSTRACT FROM AUTHOR]

- Abstract
Background: The optimal duration, safety, and benefit of preoperative chemotherapy in patients with colorectal liver metastases (CLM) are unclear. We evaluated the association between the duration of preoperative chemotherapy with 5-fluorouracil (5-FU), leucovorin, oxaliplatin (FOLFOX) ± bevacizumab, pathologic response, and hepatotoxicity after hepatic resection for CLM. Methods: A total of 219 patients underwent hepatic resection following FOLFOX with or without bevacizumab and were divided into 2 groups according to the chemotherapy duration: 1-8 cycles (short duration [SD]; N = 157) and ≥9 cycles (long duration [LD]; N = 62). The frequency of complete or major pathologic response, sinusoidal injury, and major postoperative morbidity were compared. Results: Treatment consisting of ≥9 cycles was not associated with an increase in complete or major pathologic response (SD vs. LD, 57% vs. 55%; P = .74). The incidence of sinusoidal injury was higher in the LD group (26% vs. 42%; P = .017). The incidence of liver insufficiency was higher in the LD group (4% vs. 11%; P = .035). Sinusoidal injury did not predict postoperative liver insufficiency; multivariate analysis revealed ≥9 cycles was the only independent predictor of postoperative liver insufficiency ( P = .031; odds ratio = 3.90). Chemotherapy including bevacizumab was associated with a significantly higher frequency of complete or major response in both SD and LD groups. Conclusions: Extended preoperative chemotherapy increases the risk of hepatotoxicity in CLM without improving the pathologic response. The type of chemotherapy (FOLFOX with bevacizumab) has more impact on pathologic response than the duration of chemotherapy. [ABSTRACT FROM AUTHOR]

- Abstract
Optimal margin width is uncertain because of conflicting results from recent studies using overall survival as the end-point. After recurrence, re-resection and aggressive chemotherapy heavily affect survival time; the potential confounding effect of such factors has not been investigated. Use of recurrence-free survival (RFS) may overcome this limitation. The aim of this study is to evaluate the impact of width of resection margin on RFS and site of recurrence after hepatic resection for colorectal metastases (CRM). From a prospectively maintained institutional database (1/1999–12/2007) we identified 314 patients undergone hepatectomy for CRM (1/1999–12/2007) with detailed pathologic analysis of the surgical margin and complete follow-up imaging studies documenting disease status and site of recurrence, which was categorized as: resection margin (M
arg ), other intra-hepatic (other IH), lung (L) or other extra-hepatic (other EH). Recurrence-free estimation was the survival end-point. Median follow-up was 56.5 months. Two hundred and fifteen patients (68.8%) recurred at 288 sites after a mean of 15.5 months. A positive resection margin was associated with an increased risk of Marg recurrence ( P < 0.001). The presence of ≥2 metastases was the only factor increasing the risk of positive margins ( P < 0.05). The width of the negative resection margin (≥1 cm versus >1 cm) was not a prognostic factor of worse RFS (30.2% versus 37.3%, P = 0.6). Node status of the primary tumour, and size and number of CRM were independent predictors of RFS. Tumour biology and not the width of the negative resection margin affect RFS.

- Abstract
Liver surgery is the gold-standard treatment of colorectal liver metastases. Five-year survival rates may be inadequate to evaluate surgical outcomes because some patients are alive with recurrence and late recurrences are possible. The aim of this study was to analyze 10-year survival outcome in terms of late recurrence rate and prognostic factors of survival. One hundred twenty-five patients underwent liver resection for colorectal liver metastases between 1985 and 1996. Four patients who experienced postoperative mortality were excluded. The analysis was performed on 121 patients. Five- and 10-year survival rates were 23.1% and 15.7%, respectively. Nineteen patients were alive 10 years after liver resection and 17 were disease-free (5 after re-resection). Five- and 10-year disease-free survival rates were 17.4% and 14.8%, respectively. In patients with recurrence, re-resection significantly improved survival ( P < 0.001); 98% of recurrences occurred within the first 5 years, but 15% of patients disease-free at 5 years developed later recurrence. Multivariate analysis evidenced five independent negative prognostic factors of survival: male sex ( P = 0.029), synchronous metastases ( P = 0.011), >3 metastases ( P < 0.001), metastatic infiltration of nearby structures ( P < 0.001), and postoperative morbidity ( P < 0.001). In 17 patients without negative prognostic factors the 10-year survival rate was 35.3%. Liver resection for colorectal liver metastases may be curative in more than one-third of patients without negative prognostic factors. Postoperative morbidity significantly worsens long-term outcomes. The risk of recurrence after liver resection is high even after 5 years of follow-up, but re-resection can improve the outcome.

- Abstract
The most accepted treatment for locally advanced pancreatic cancer is chemoradiotherapy. However, indications to and results of pancreatic resections after chemoradiation are not yet defined. From June 1999 to December 2003, 28 patients with locally advanced pancreatic cancer (group 1) were enrolled for institutional trials of gemcitabine-based chemoradiotherapy. Tumors were stratified as unresectable or borderline resectable according to the pattern of vascular involvement at pretreatment computed tomographic scan. Patients with partial response or stable disease and in-range Ca19-9 were surgically explored. Perioperative outcome and survival of group 1 were compared with 44 patients primary resected for localized cancer with or without adjuvant treatment in the same time period (group 2). Only one unresectable tumor was successfully resected compared to 7 out of 18 (39%) that were borderline resectable. Operations after chemoradiation were 1 hour longer and postoperative stays 5 days longer, but transfusion rate, morbidity, and mortality were not significantly different. Median survival was 15.4 months for group 1 (>21 for resected vs. 10 for not resected, P < 0.01) and 14 months for group 2. In both groups, a disease-free survival beyond 24 months was recorded only among patients resected with negative margins. The conversion of an unresectable cancer to a resectable one is a rare event. On the contrary, the resection of a borderline resectable tumor was successfully accomplished in one-third of cases. Chemoradiotherapy did not increase the operative risk, but the interventions were more technically demanding and required a longer postoperative stay. Patients resected after chemoradiation for a locally advanced tumor had at least the same survival as those primary resected for a localized one. Only R0 resections in both groups gave the chance of disease-free survival longer than 24 months. [ABSTRACT FROM AUTHOR]

- Abstract
Resection of melanoma metastatic to the liver remains controversial. We evaluated the efficacy of hepatic resection in patients with metastatic ocular and cutaneous melanoma and assessed factors that could affect survival after resection. Forty patients with hepatic melanoma metastasis underwent resection at four major hepatobiliary centers. Clinicopathologic factors were evaluated with regard to recurrence and survival by using χ
2 and log-rank tests. The primary tumor was ocular in 16 patients and cutaneous in 24. The median disease-free interval from the time of primary tumor treatment to hepatic metastasis was the same for both groups (ocular, 62.9 months; cutaneous, 63.1 months; P = .94). Most patients underwent either an extended hepatic resection (37.5%) or hemihepatectomy (22.5%). Twenty-six patients (65%) received perioperative systemic therapy. Thirty (75.0%) of 40 patients developed tumor recurrence. The median time to recurrence after hepatic resection was 8.3 months (ocular, 8.8 months; cutaneous, 4.7 months; P = .3). Patients with primary ocular melanoma were more likely to experience recurrence within the liver (53.3% vs. 17.4%; P = .015), whereas patients with a cutaneous primary tumor more often developed extrahepatic involvement. The 5-year survival rate for patients with a primary ocular melanoma was 20.5%, whereas there were no 5-year survivors for patients with cutaneous melanoma ( P = .03). Patterns of recurrence and prognosis after resection of hepatic melanoma metastasis differ depending on whether the primary melanoma is ocular or cutaneous. Resection should be performed as part of a multidisciplinary approach, because recurrence is common. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Mortality and morbidity rates after liver resections have decreased with better surgical techniques and perioperative care. The aim of this study was to evaluate the short- and longterm results in patients who had undergone extensive hepatectomies. From January 1985 to December 2000, 237 patients underwent 275 liver resections for colorectal metastases. Extensive liver resections were defined as follows: technical reasons (extended hepatectomies, associated vascular resections); disease extent (diameter, ≫10 cm; number, ≫5; associated extrahepatic resection). The total number of extensive liver resections was 74. There were 51 radical resections (68.9%), while in the nonextensive resections group, 152 resections were radical (90.7%; P = 0.1). Postoperative mortality (60 days) was 1.6% (1.3% in the extensive resections group; P = 0.3), while morbidity was 22.7% (31% in the extensive resections group vs 19% in the nonextensive resections group; P = 0.1). One-, 3-, and 5-year overall actuarial survival rates were 91.8%, 44.9%, and 25.3%. The survival rates of patients who underwent an extensive resection were similar to those in the nonextensive resections group. Technical difficulties and neoplastic extension are not, nowadays, a contraindication for hepatectomy for colorectal liver metastases, unless a radical resection is performed. [ABSTRACT FROM AUTHOR]

Sixteen gastrectomized patients underwent surgical treatment for alkaline reflux gastritis by means of a Roux-en-Y loop duodenal diversion. Long-term evaluation of results was performed 5-9 years later. Ten patients (62.5%) showed good results, with absence of digestive symptoms and with an increase in body weight. Two patients (12.5%) had moderate results, with presence of sporadic and mild epigastric pain. Four patients (25%) had unsatisfactory results, with persistence of epigastric pain and absence of body weight increase. No patient had recurrent biliary vomiting or endoscopic evidence of endogastric biliary reflux. Among the six patients with moderate and unsatisfactory results, two had a significant alcoholic intake, two showed a high degree of anxiety on psychological assessment, and two had both factors. Alcoholism and psychological disturbances should be considered exclusion criteria when evaluating a gastrectomized patient for surgical cure of alkaline reflux gastritis. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 66-year-old man with perforated rectal cancer and Fournier's gangrene. He underwent abdominoperineal resection (APR) and immediate pelvic floor reconstruction (PFR) requiring the combination of different techniques including omentoplasty, transabdominal biological mesh application, and the vacuum-assisted closure (VAC) system. It suggests that the combination of these techniques may allow successful management of large perineal defects.
