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.

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 ≤15 (group 2, n = 432) lymph nodes examined were separately analyzed. N ratio categories (N ratio 0, 0%; N ratio 1, 1%–9%; N ratio 2, 10%–25%; N ratio 3, >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.

BACKGROUND The treatment of hepatic metastases from gastric cancer is controversial, due to biologic aggressiveness of the disease. OBJECTIVE To survey the clinical approach to the subset of patients presenting with metachronous hepatic metastases as sole site of recurrence after curative resection of gastric cancer, focusing on the results achieved by different therapies and to investigate the prognostic factors of major clinical relevance. METHODS Retrospective multi-center chart review evaluating 73 patients, previously submitted to D >or= 2 gastrectomy for gastric cancer, who developed exclusive hepatic recurrence. Prognostic factors related to the patient, to the gastric malignancy and its treatment, and to the metastatic disease and its therapy were evaluated. RESULTS Forty-five patients received supportive care, 17 were submitted to chemotherapy, and 11 to hepatic resection. Survival was independently influenced by the variables T (p=0.019), N (p=0.05) and G (p=0.018) of the gastric primary and by the therapeutic approach to the metastases (p<0.005). In particular, T4 gastric cancer, presence of lymph-node metastases and G3 tumor displayed a negative prognostic value. Therapeutic approach to the metastases was the principal prognostic variable: 1, 2, and 3 years survival rates were 22.2%, 4.4% and 2.2%, respectively, for patients without specific treatment; 44.9%, 12.8% and 6.4% after chemotherapy (p=0.08) and 80.8%, 30.3% and 20.2% after surgical resection (p<0.001). CONCLUSIONS Our data suggest some clinical criteria that may facilitate selection of therapy for patients with hepatic recurrence after primary gastric cancer resection. The best survival rates are associated with surgical treatment, which should be chosen whenever possible.

Doppler above-ankle pressure index (API) was monitored during 368 consec utive bilateral aortoiliac or aortofemoral graft reconstructions performed for aneurysmal or occlusive disease. The aim of this study was to investigate the variations of peripheral pressure, during and just after completion of the proce dure, either when followed by immediate and definitive success or when an intraoperative correction or an early postoperative reoperation was necessary owing to postreconstructive ischemia. For this purpose the API courses were subdivided into three groups: A (705 limbs), which underwent immediately suc cessful reconstructions; B (22 limbs), which needed intraoperative correction; C (9 limbs), which required early reoperation. All 736 limbs were studied individ ually as monolateral reconstructions and classified into six subgroups: 1, pervi ous iliac, pervious femoral artery; 2, occluded iliac, pervious femoral; 3, pervi ous iliac, stenotic femoral (i.e, stenosis > 75% of the superficial femoral artery); 4, occluded iliac, stenotic femoral; 5, pervious iliac, occluded femoral; 6, oc cluded iliac, occluded femoral. APIs were monitored before the operation (PRE), at the completion of the distal anastomosis (DEC), and five, fifteen, thirty, and forty-five minutes after. Data were statistically analyzed by multivariate analysis in regards to 705 immediately successful limbs (group A) and by comparison of all corrected or reoperated cases (groups B and C) with the lower bound of the fifth centiles of group A. The results in group A show that: API-PRE is different in the six subgroups (p < 0.001); API-DEC is lower than API-PRE in the patent iliac artery sub groups (1,3, and 5) and higher than API-PRE in the occluded iliac artery sub groups (2,4, and 6) (p always < 0.001). From declamping time to the forty-five- minutes observation, the mean courses turn out parallel and rising but on dif ferent levels (p < 0.001): pervious femoral, stenotic femoral, occluded femoral. API-forty-five minutes is higher than API-PRE in occluded iliac artery subgroups (2, 4, and 6) (p < 0.001), whereas in the patent iliac artery subgroups only the fifth subgroups reveals a slight but significant rise (p < 0.01), probably owing to the high rate of profunda femoral endarterectomy or angioplasty asso ciated with aortofemoral reconstructions. APIs values of 31 cases in groups B and C, compared with the lower bound of the fifth centile of group A, show that 8/31 cases (26%) remain above that bound, while 23/31 cases (74%) fall below it.

Stefano Maria Giulini; Aldo Colombi; Stefano Bonardelli; Roberto Maffeis; Maurizio De Lucia; Arianna Coniglio; Fabio Tosoni; Marco Floriani; Giorgio Tiberio

From March 1980 to February 1988, 368 aorto-iliac or aorto-femoral bilateral reconstructions were performed for aneurysmal or occlusive disease. In order to demonstrate early postreconstructive ischaemic complications, the intra-operative Doppler Ankle Pressure Index (API) was measured immediately before reconstruction (PRE), just after declamping (DEC) and 5, 15, 30 and 45 min thereafter. Each limb of the reconstruction (736) was considered individually and subdivided as follows: Group (A) 705 immediately successful (96% of limbs and 92% of patients); Group (B) 22 (3% of limbs and 5% of patients) in which, on the grounds of API data, an ischaemic complication was regarded as imminent and treated by graft revision or a peripheral thromboembolectomy (intra-operative corrections); Group (C) 9 (1% of limbs and 2% of patients) in which the diagnosis of ischaemic complications was made postoperatively when the patients underwent successful reoperation. All 736 reconstructions were patent and functional at discharge of the patient. By a retrospective analysis the intra-operative APIs were studied and the features (single or associated) suggesting an ischaemic complication examined. These were: (1) no flow at the time of declamping or its disappearance during the operation (10 cases, 1.25% of limbs) all detected and successfully corrected intra-operatively.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgical Treatment of Liver Metastases from Gastric Cancer

Guido A. M. Tiberio; Arianna Coniglio; Gian Luca Baiocchi; Stefano Maria Giulini

After a brief description of the clinical characteristics of hepatic metastases from gastric cancer and their different clinical settings, we discuss the natural evolution of the disease, focusing on the extremely poor prognosis of these patients. Through a complete review of the literature, the chapter provides detailed insight into the different therapeutic options, discussing their indications, patient selection criteria, and results. We argue that a correct therapeutic approach can offer to a relatively large percentage of patients (≈ 40%) an unexpected 20–40% 5-year survival rate. Our main purpose is to convey the cultural basis that will induce the reader to reconsider the largely predominating passive attitude toward these patients by acknowledging the opportunity to offer better and longer survival to a selected subgroup.

Iatrogenic extracranial carotid dissection : report of two cases treated surgically

Giorgio Tiberio; Stefano Maria Giulini; Luigi Cangiotti; Marco Floriani; Arianna Coniglio; Paolo Mulesan; Stefano Bonardelli

Two patients had an acute dissection of the right common carotid artery due to catheterization of the vessel during Seldinger angiography. Both patients were evaluated immediately after the traumatic event by means of echo-pulsed Dop pler (duplex scan) to check the hemodynamic significance of the lesion. In the first case, the lesion initially appeared insignificant, but on the second day duplex scanning showed a sudden reduction of the flow in the internal carotid artery due to progression of the carotid dissection: the patient, neurologically asymp tomatic, was operated on successfully. The second patient, also asymptomatic, underwent emergency surgical treat ment after the first duplex scan showed significant reduction of the internal carotid flow. The postoperative course has been uneventful. Both patients are asympto matic eighteen and eight months after surgery. The authors emphasize the important role that duplex ultrasonography played in the management of these 2 patients.
