Abstract
AIM Metastases from colorectal cancers rarely occur in injured livers, however this phenomenon has not been fully investigated in patients with different degree of liver damage. Therefore in this study we evaluated the incidence of synchronous hepatic metastases in patients with fatty or cirrhotic liver submitted to surgery for colorectal neoplasms. METHODS Seven hundred and forty-seven patients undergoing surgical treatment for colorectal neoplasms were evaluated: the clinicopathological data of 171 patients with liver cirrhosis and 33 with fatty liver were compared to those of 543 patients without liver damage. RESULTS Gender, age, type of operative procedures performed and histological grading were similar in patients with or without liver damage. In patients with liver cirrhosis the incidence of stage II tumour was greater, while stage IV tumours (P < 0.001) and nodal involvement were significantly lower than in patients with non injured or fatty liver (P < 0.02 and P < 0.001 respectively) . At the time of surgery, synchronous hepatic metastases were present in 32% of patients with normal liver, in 15% of patients with fatty liver (P < 0.02) and in 4.7% of patients with liver cirrhosis (P < 0.001). CONCLUSIONS Results of our study show that synchronous hepatic metastases of colorectal cancer are less frequently observed in patients with fatty or cirrhotic liver than in patients with non injured liver, indicating that chronically damaged livers are protected from the spread of secondary cancers.

Abstract
AIM Metastases from colorectal cancers rarely occur in injured livers, however in western countries this phenomenon has not been investigated in patients with various forms of chronic hepatitis. Therefore in this study we evaluated the incidence of synchronous hepatic metastases of colorectal carcinomas in patients with hepatitis B (HBV) or C (HBC) infection. METHODS Six hundred and thirty patients undergoing surgical treatment for colorectal carcinomas were analysed: the clinicopathological data of 87 patients with HBV or HCV infection (there were 29 patients with hepatitis C infection and 58 with hepatitis B infection) were compared to those of 543 non infected patients. RESULTS Patients distribution was similar in both groups in terms of gender, age, type of operative procedures performed, histological grading and lymph node metastases. Stage I, II or III tumours were similarly represented in non infected and infected patients, while stage IV tumours were 33.1% in the non infection group and 17.2% in the infection group (P < 0.001). At the time of surgery, synchronous extrahepatic metastases were present in 14.9% of non infected patients and 15% of infected patients, while synchronous hepatic metastases were found in 32% and 17.2% of patients respectively (P < 0.01). CONCLUSIONS Results of our study show that synchronous hepatic metastases of colorectal cancers are less frequently observed in chronic HBV or HCV infected patients than in non infected patients, while the incidence of extrahepatic metastases is comparable in both groups, suggesting that virus-related mechanisms and specific liver mediated immunity may have a protective role against neoplastic cell colonization of the liver.

Axillary lymphectomy in breast cancer. MINERVA CHIR 2002; 57:129-33. [PMID: 11941288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/24/2023]
Abstract
BACKGROUND The aim of the study was to demonstrate the prognostic value of sentinel node biopsy compared to the sampling of clinically suspected nodes and lymphectomy of the 3 axillary levels. METHODS. From October 1996 to January 1999, 60 patients with breast cancer with a diameter of 4 cm or under using different procedures of axillary lymphadenectomy. Sentinel node biopsy was performed using Giuliano's technique, followed by lymph nodes larger than 5 cm (lymph node sampling) and lastly all axillary lymph nodes (axillary lymphectomy at 3 levels). RESULTS Sentinel nodes were identified in all patients and a mean of 3 sentinel nodes (range 1-5) were removed during the procedure. Histological analysis showed metastatic sentinel nodes in 21 cases. Lymph node sampling was possible in 43 patients who presented enlarged nodes. The mean number of lymph nodes removed was 6 (range 3-10). Lymph node metastasis was found in 10 patients and of these 7 had a metastatic sentinel node, whereas 3 had presented negative results. Histological tests in all 60 cases of complete axillary lymphectomy showed positive results in 4 cases confirming metastasis present in sentinel nodes. CONCLUSIONS The results show that the association of lymph node sampling can improve the efficacy of sentinel node dissection, highlighting the rare cases of false negatives. In our study, total axillary lymphectomy did not add any information to the N parameter and was resolutive in a small percentage of cases.

Abstract
A 58-year-old Italian man was incidentally discovered to have an elevated carbohydrate antigen 19-9 (CA-19-9) level of 132 U/mL on routine blood testing. Multisystem imaging studies revealed multiple benign-appearing cysts of the liver and single cysts in the pancreas and kidney parenchyma. Throughout 14 months, fluctuations were observed in the elevated serum CA-19-9 levels from 99 to 450 U/mL. Serum carcinoembryonic antigen (CEA) and other tumor markers were normal. Laparoscopy disclosed multiple cystic lesions on the surface of the liver, on the serosal surface of the ileum, and in the mesentery. Electron microscopy characterized the cells as mesothelial. The pathologic diagnosis was benign multicystic mesothelioma of the peritoneum (BMMP). Aspirated fluid from the liver cyst revealed CA-19-9 levels at 28 500 U/mL, strongly linking the elevated serum CA-19-9 levels with mesothelial cyst secretion. Immunostaining was positive for CA-19-9, CEA, and cancer antigen 125 (CA-125). We believe this is the first documented instance of CA-19-9 and CEA secretion in BMMP.

Abstract
BACKGROUND The aim of the study is to demonstrate the feasibility and the oncologic effectiveness of quadrantectomy plus sentinel node biopsy performed under local anesthesia, and to demonstrate the economic and psychologic advantages. METHODS From October 1996 to March 2000, 71 patients affected with clinical T1 N0 breast cancer, underwent quadrantectomy or tumor resection plus sentinel node biopsy and clinically suspicion axillary nodes biopsy, under local anesthesia at the Casa di Cura "Villa Mafalda" in Rome. RESULTS Twenty tumors were T1a, 26 T1b e 25 T1c. A mean of 2 sentinel nodes (range 1-4) and a mean of 8 axillary nodes were removed during the procedure. In 2 cases sentinel nodes were not identified. Intraoperative histologic examination showed metastatic sentinel nodes in 11 cases. An axillary node dissection was performed in all cases (>12 nodes) and no other metastatic nodes were found. In all patients clinically suspected nodes were removed. In two cases no evidence of metastasis was found in sentinel nodes, while histologic examination revealed in a patient micrometastasis in one node, and in another patient two metastatic nodes. CONCLUSIONS Fifty-three patients rated the overall surgical, anesthetic and recovery experience as "very satisfactory", 13 "satisfactory" and 5 "unsatisfactory". Patients typically expressed their pleasure at the possibility to return home and stressed the ease of recovery.

Abstract
The purpose of this report is to describe the technique of liver resection using an endovascular stapling device. A total of 31 patients underwent major hepatic resections with stapling techniques. The authors have used various approaches to portal structures and hepatic veins with the application of a vascular endostapler device. The specific techniques of different hepatectomies are described and illustrated. There were no deaths. A minor complication (biliary fistula) occurred in one patient, related to binary leak from parenchymal transection. No complications directly attributable to stapler ligations of portal pedicle or hepatic veins were observed. Stapling techniques can be helpful in major hepatic resection procedures. The vascular endostapler can significantly reduce both portal vein and hepatic vein closure time and may expedite the transection of the liver, eliminating the risk of slipped ligature following simple ligation.

The basic residues of placenta growth factor type 2 retrieve sequestered angiogenic factors into a soluble form: implications for tumor angiogenesis.

Abstract
Placenta growth factor type 1 (PIGF-1) can be synthesized by neoplastic cells in an alternative form (PIGF-2) by the addition of basic amino acids to its classic sequence. Here we show that the basic residues of PIGF-2 compete for the binding of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) to heparan sulfate proteoglycans of the cell surface and extracellular matrix. In doing so, PIGF-2 basic sequences inhibit the sequestering of VEGF and bFGF and maintain them in a highly diffusible form, thus enhancing their angiogenic effect. In agreement with these in vitro data, the presence of PIGF-2 transcripts in tumors correlates with their blood vessel number. These results suggest a mechanism by which growth factor isoforms produced by neoplastic cells enhance the formation of new blood vessels supporting tumor growth and progression.

Abstract
This prospective randomized trial compares the results of i.v. omeprazole and i.v. ranitidine in 45 patients admitted as an emergency with an endoscopic diagnosis of bleeding duodenal ulcer. The patients were randomized to receive i.v. omeprazole, 40 mg bolus followed by 80 mg/day by continuous infusion for 3 days (group A), or ranitidine 50 mg i.v. bolus followed by 400 mg/day i.v., continuous infusion for 3 days (group B). Follow-up endoscopy on day 4 demonstrated successful therapy, except when more than 4 units of blood/day had to be transfused to maintain hemoglobin level above 10 g/l. Bleeding stopped in 20/21 patients in group A (95.2%), and in 17/24 patients in group B (70.80%) (p < 0.05). From the results of the study, it can be concluded that intravenous omeprazole seems to be effective in the control of bleeding duodenal ulcer.

Abstract
A chart review was conducted on 28 patients with gastric stump cancer who were radically treated at the First Department of Surgery of University "La Sapienza" of Rome between 1978 and 1990. The data obtained were compared with those of 401 patients radically treated, in the same period, for primary cancer of the proximal third of the stomach. There were no significant differences between the two groups in terms of stage and nodal involvement. Surgical treatment was total gastrectomy in 86% of cases, and an extended procedure in 57% of patients. The morbidity rate was similar to patients treated for primary gastric cancer, as well the 5-year survival, which depend on the stage of disease. We can conclude that gastric stump cancer must be treated surgically with radical intent as the prognosis is similar to that of primary gastric cancer.

Abstract
The aim of the study was to compare the results of ultrasonography (US) and laparoscopy in a series of 210 patients referred to our institution for the diagnosis of widespread liver diseases. Among 205 patients, laparoscopy revealed cirrhosis in 114, chronic widespread disease in 70 (chronic persistent hepatitis in 21, chronic active hepatitis in 28, steatosis in 14, acute hepatitis in 5, fibrosis in 2), and absence of liver disease in 21. Four of these cases had minor complications. A corroborative diagnosis was obtained in 122 patients (59.5%). Overall sensitivity of US was 84% with a low specificity due to the high rate of false negatives. From the results of this study we conclude that laparoscopy is a safe and essential diagnostic tool in the final diagnosis of widespread liver diseases and that US is not a reliable screening method because of its incidence of false negatives.

Abstract
It is a common opinion that the more often and the more rigorously the colon is examined, the more lesions will be discovered and diagnosed. However it has not been shown which methods of colonic examination and which regimen of surveillance should be used. Chart review was conducted on 481 patients who underwent curative resection for colorectal cancer between 1980 and 1990. Colonoscopy was performed preoperatively, after 12-15 months from surgical treatment, and then at an interval of 12-24 months, or when symptoms appeared. About ten percent of patients developed intraluminal recurrences, and more than 25% adenomatous polyps. More than one half of the metachronous lesions arise within the first 24 months. The median time to diagnosis was 25 months for intraluminal recurrences and 22 months for adenomatous polyps. Patients with left sited tumor at an advanced stage run a higher risk of developing recurrent intraluminal disease, and patients who presented associated polyps at the time of the operation for the index cancer have a higher risk of developing new polyps. About 50% of recurrences were detected when patients were asymptomatic. Colonoscopy must be performed within the first 12-15 months after operation, while an interval of 24 months between each examination seems sufficient to guarantee an early detection of metachronous lesion. Asymptomatic patients are more frequently reoperated for cure and thus have a better survival rate.

Abstract
PURPOSE The authors evaluate the effectiveness of routine colonoscopy and marker evaluation in diagnosis of intraluminal recurrent cancer. METHODS Chart review was conducted on 481 patients who underwent curative resection for colorectal cancer between 1980 and 1990. Clinical visits were scheduled and carcinoembryonic antigen evaluation was performed every three months, and colonoscopy was performed preoperatively, 12 to 15 months after surgical treatment, and then with intervals of 12 to 24 months or when symptoms appeared. RESULTS About 10 percent of patients developed intraluminal recurrences. More than one-half of metachronous lesions arose within the first 24 months, and median time to diagnosis was 25 months. Patients with left-sited tumors in the advanced stage had a higher risk of developing recurrent intraluminal disease. Twenty-nine patients underwent a second surgical operation, of which 17 cases were radical. In this group, the five-year survival was 70.6 percent, although no nonradically treated or nonresected patients survived longer than 31 months. Twenty-two patients were asymptomatic at time of diagnosis of recurrence, and of these, 12 patients underwent radical operation; on the other hand, of the 24 symptomatic patients, only 5 were treated radically. Carcinoembryonic antigen was the first sign of recurrence in eight cases. Colonoscopy must be performed within the first 12 to 15 months after operation, whereas an interval of 24 months between examinations seems sufficient to guarantee early detection of metachronous lesions. CONCLUSION Serial tumor marker evaluation is of help in earlier diagnosis of local recurrences. Asymptomatic patients more frequently undergo another operation for cure and thus have a better survival rate.

Abstract
Between 1989 and 1991, 66 women affected by breast cancer smaller than 2 cm in diameter, were treated with conservative procedure plus radiotherapy. Conservative procedure consisted in quadrantectomy and axillary dissection of the 3 axillary nodes levels. Neoplasms were grouped according to TNM classification. Eleven were classified as Tis, 9 as T1aN0M0, 12 as T1bN0M0, one case T1bN1M0, 24 as T1cN0M0 and finally 9 as T1cN1M0. Actuarial 5-year survival rate was related to TNM. It has been reported to be 100% in Tis and T1aN0M0 neoplasms; 91.7% in pT1bN0M0 tumors, 95.8% in pT1cN0M0 neoplasms, 55.6% in patients affected with pT1cN1M0 tumors. According to the relationship between receptor status of the neoplasm and survival, this was 88.9% in ER+ and 77.8% in ER- tumors, and 97.1% against 71.4% (p < 0.05) in PR+ and PR- neoplasms respectively. Two patients presented (3%) local recurrence which were treated by means of a tumorectomy and radiotherapy. Both patients are still living and disease free after 6 and 9 months from re-operation.

Abstract
One-hundred seventy four consecutive patients who underwent curative resection for gastric and colorectal cancer between 1983 and 1985, were studied prospectively to evaluate the roles of sequential CEA, TPA and GICA determinations and independent clinical examinations, in the early diagnosis of resectable recurrences. Sixty-six recurrences (33 from gastric and 33 from colorectal cancer) were detected between 6 and 42 months after primary surgery. In gastric cancer CEA, TPA and GICA showed a sensitivity of 64%, 73%, and 60%, and a specificity of 67%, 65% and 54% respectively. Nine patients (27%) underwent surgical treatment for the recurrent disease, and 4 of them (44.4%) had resectable recurrence, for a total resectability rate of 12%. Out of these four patients, three patients are still living after 12, 36 and 44 months respectively from re-operation without evidence of neoplastic disease. In one of these patients re-operation was performed on the basis of the elevation of the three markers, without any other clinical sign of disease, this patient had a resectable solitary hepatic recurrence. In colorectal cancer CEA, TPA and GICA showed a sensitivity of 73%, 73%, and 49%, and a specificity of 77%, 87%, and 97% respectively. Fourteen patients (42.4%) underwent surgical treatment for the recurrent disease, and 8 of them (57%) showed a resectable recurrence, for a total resectability rate of 24.2%. Six patients are still living after 9, 16, 21, 31, 41 and 53 months respectively from reoperation without evidence of neoplastic disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The clinical course of patients with hematological disease, especially after treatment, is often complicated by gastrointestinal infections. Between 1986 and 1990 a total of 18 patients affected with hematologic disease and presenting with an acute abdomen were admitted to the surgery department at the University of Rome "La Sapienza". Most patients were affected with acute or chronic myeloid leukemia (61%) and lymphoma. Five patients with acute appendicitis, three with necrotizing enterocolitis, three with spontaneous hemoperitoneum, three with cholecystitis, two splenic infarctions and two intestinal occlusions were diagnosed. Symptoms were often vague and non specific and blood counts revealed neutropenia in all but two patients, while anemia was characteristic in spontaneous hemoperitoneum and in neutropenic enterocolitis. Fungemia occurred in only two cases while bacteremia was present in seven. The most critical patients were those affected by neutropenic enterocolitis and acute cholecystitis. Sonography was meaningful in the diagnosis of hemoperitoneum, splenic infarct and acute cholecystitis. All patients underwent surgical procedures within 48 hours of admission to the department. In all cases peritoneal washing was performed and at least one peritoneal drainage was left. In all cases of necrotizing enterocolitis, intestinal resections, either ileal or colonic, were followed by an immediate anastomosis in two layers. Intensive hematological and antibiotic post surgical care was performed in all patients. Seven patients presented minor complications (38.8%), and only one died (5.5%). Emergency surgical treatment may be safely carried out in patients with hematological diseases presenting with an acute abdomen. Intensive postsurgical care is mandatory for the recovery of patients and the patient's critical condition should not be a deterrent to surgical intervention.

Abstract
Pleural mesotheliomas are rare, and their diagnosis and treatment not clear. The case observed in our Department leads us to an analysis of the literature. This showed that differential diagnosis with pulmonary carcinoma is very difficult, even in cases of parietal mesothelioma; however local treatment may be performed even in malignant mesothelioma.

Abstract
Between 1978 and 1984 a consecutive series of 571 patients with colorectal cancer were admitted to the First Department of Surgery of the University of Rome. Patients were divided into a group of 82 patients affected with obstructive cancer and a control group of 489 patients with non-obstructive tumors. In the obstructed group there was a significantly higher incidence of lesions localized in the left colon. Depending on the advancement of lesions a significantly higher incidence of Dukes D tumor, nodal involvement, hepatic metastases and peritoneal dissemination and a significantly lower incidence of Dukes A tumors, were found in the obstructed patients. No significant differences were found in the two groups according to age distribution, duration of symptoms and degree of differentiation of neoplasms. The mortality and morbidity rate were 9.7% and 12.2% respectively in the obstructed patients, and 3.5% and 8.3% respectively in the non-obstructed patients. The rate of complications was greater in the two groups when serum albumin values were under 3 g/l, being 40% vs. 3.3 and 20% vs. 5.2% in obstructed and nonobstructed groups respectively. When Hb levels were under 10 g/l the incidence of complications was 16.7% and 14.4% for the two groups, while when it was higher than 10 mg% the morbidity rate was 8.7% and 6.3% in obstructed and non-obstructed patients respectively. The execution of surgical treatment within 24 hours was related to a morbidity and mortality rate of 50% and 22.2% in obstructed patients, and 40% and 20% in the non-obstructed group.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The role of surgery in the treatment of immune thrombocytopenic purpura (ITP) is still discussed. The aim of this study was to verify our criteria of patient selection for splenectomy, to analyze the results of a protocol for the evaluation of the hemorrhagic risk, and to discuss long-term results of 70 patients with ITP who underwent surgical treatment from 1984 to 1990. All patients received steroid therapy. Sixty-two patients were given high doses of IgG (600 mg/kg/iv bolus) pre-operatively in order to obviate the need for intra-operative platelet transfusions. Forty-three patients showed a significant increase in the platelet count, 8 a moderate increase, while 11 patients did not respond. No operative mortality was observed, however postoperative minor complications occurred in 14 (20%) patients. Accessory spleens were found in 11 (15.7%) patients. Mean follow-up was 21 months. Response to splenectomy was considered as complete (platelets greater than 150,000 mm3 with no need for medical treatment) in 63 (90%) patients. No response was observed in 7 patients. In 2 of the non-responders postoperative indium-111 scan revealed accessory spleens and ITP remitted after accessory splenectomy. All non-responders were in the group of patients who did not respond to the pre-operative infusion of high dose IgG. It can be concluded that splenectomy is a safe and effective treatment for ITP and that response to pre-operative infusion of IgG may be considered as predictive for the outcome after splenectomy.

Abstract
Sixty-six consecutive patients who underwent curative resection for rectal cancer were studied prospectively to evaluate the roles of sequential carcinoembryonic antigen (CEA), tissue plasminogen activator (TPA), and carcinomatous antigen 19-9 (Ca 19-9) determinations in the early diagnosis of resectable recurrences. Thirty-three recurrences were detected between 6 and 42 months. CEA, TPA, and Ca 19-9 showed a sensitivity of 72.7 percent, 78.8 percent, and 60.1 percent, respectively, and a specificity of 60.6 percent, 60.6 percent, and 87.9 percent, respectively. In 23 cases the rise in the value of CEA and/or TPA and/or Ca 19-9 was the first sign of recurrences, and the diagnosis was established later by clinical methods. In this group, the lead time was two months for liver metastases and four months for disseminated metastases. As far as the relationship between localization of recurrence and marker level increase is concerned, of 16 hepatic metastases CEA, TPA, and Ca 19-9 showed a sensitivity of 94 percent (P less than 0.05), 69 percent, and 62 percent, respectively. Of six patients with local recurrences, CEA, TPA, and Ca 19-9 showed a sensitivity of 50 percent, 100 percent (P less than 0.05), and 83.3 percent, respectively. Of three patients with peritoneal carcinomatosis, CEA, TPA (P less than 0.05), and Ca 19-9 showed a sensitivity of 0 percent, 100 percent, and 0 percent, respectively. No significant differences were reported among the three markers according to multiple metastases and metachronous polyps. Fourteen patients (42.4 percent) underwent surgical treatment for recurrent disease, and eight of them (57 percent) showed a resectable disease, for a total resectability rate of 24.2 percent. The findings of our study indicate that a follow-up program based on CEA, TPA, and Ca 19-9 assays is related to an early diagnosis and a good resectability rate for both local and metastatic recurrences from rectal cancer.

Abstract
One-hundred and seventy-four consecutive patients who underwent curative resection for gastric and colorectal cancer between 1983 and 1985 were studied prospectively to evaluate the roles of sequential carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA) and Ca 19-9 determinations and independent clinical examinations, in the early diagnosis of resectable recurrences. Sixty-six recurrences (33 from gastric and 33 from colorectal cancer) were detected between 6 and 42 months after primary surgery. In gastric cancer CEA, TPA and Ca 19-9 showed a sensitivity of 64%, 73% and 60% respectively and a specificity of 67%, 65% and 54% respectively. Nine patients (27%) underwent surgical treatment for recurrent disease, and four of these (44.4%) had resectable recurrence, for a total resectability rate of 12%. Of these four patients, three are still living after 12, 36 and 44 months respectively from re-operation without evidence of neoplastic disease. In one of these patients, re-operation was performed on the basis of the elevation of the three markers, without any other clinical sign of disease. This patient had a resectable solitary hepatic recurrence. In colorectal cancer. CEA, TPA and Ca 19-9 showed a sensitivity of 73%, 73% and 49% respectively, and a specificity of 77%, 87% and 97% respectively. Fourteen patients (42.4%) underwent surgical treatment for recurrent disease and eight of these (57%) showed resectable recurrence, for a total resectability rate of 24.2%. Six patients are still living after 9, 16, 21, 31, 41 and 53 months respectively from re-operation without evidence of neoplastic disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Personal experience is reported of 47 consecutive liver resections for metastatic colorectal carcinoma treated in the I Clinica Chirurgica of the University of Rome for the purpose of contributing to treatment and evaluating the clinical factors and possible determinants of prognosis that could be potentially predictive of outcome and length of survival after liver resection: Duke's stage of primary colorectal cancer, synchronous or metachronous disease, number of hepatic lesions. Patients were classified according to the proposed staging system of the "Istituto Nazionale Tumori" in Milan. For Stage I and II patients the median survival time was 15 months, while in Stage III patients survival time was reduced to only 4.5 months. The 3- and 5-year survival rate was 20% and 12% respectively for Stage I patients; no patients at stage II or III survived more than 3 years.

Abstract
Colonoscopy and air-contrast barium enema performed preoperatively in 389 patients with colorectal cancer revealed synchronous cancer in 4% and polyp in 14%. Nine of the 16 synchronous cancers were located in other surgical segments than the index cancer, and six of the nine were in stage A or B1. Of the 54 synchronous polyps, 28 were located in such other segments. Half of the synchronous cancers and almost half of the synchronous polyps were missed at double-contrast barium enema. All synchronous cancers and three-fourths of the synchronous polyps were detected at colonoscopy. No patient with preoperative colonoscopy presented with metachronous cancer within 3 years from surgery, and only two were subsequently found to have adenocarcinoma arising from an adenomatous polyp. Endoscopic polypectomy was performed in 21 cases during follow-up. Extensive use of preoperative colonoscopy is recommended in the evaluation of colorectal cancer, in order to promote detection of synchronous tumors, reduce the incidence of 'early metachronous' cancer and avoid malignant degeneration of adenomatous polyp.

Abstract
Eighty-eight consecutive patients who underwent curative resection for colorectal cancer between 1983 and 1985 were studied prospectively to evaluate the roles of sequential CEA, TPA and CA 19-9 determinations and independent clinical examination in the early diagnosis of resectable recurrences. Twenty nine recurrences were detected between 8 and 38 months after primary surgery. CEA, TPA and CA 19-9 showed a sensitivity of 72%, 62% and 38%, and a specificity of 78%, 86% and 97%, respectively. Of eight recurrences in which CEA was not raised, five induced a rise in TPA and two a rise in CA 19-9. The rise in the serum concentration of one of the three markers was the first sign of relapse in 23 (79%) patients. Two second-look laparotomies based solely on a rise in serum markers were performed. In one case diffuse recurrent disease was found, and in the other a resectable solitary hepatic metastasis was found.

Abstract
The results of surgical treatment of hepatic metastasis from stomach and colo-rectal cancer in a series of 28 patients have been assessed. 21 cases were subjected to hepatic resection (stomach cancer: 7 cases; colorectal: 14 cases) and 7 underwent locoregional chemotherapy through the gastroduodenal artery with fully implantable catheters (stomach ca.: 1 case; colorectal ca.: 6 cases). Of patients who underwent hepatic resection, 3 died postoperatively and 4 are still alive 5 years after the operation. Of the 7 patients treated with locoregional chemotherapy, 4 can be evaluated: 2 responded to treatment, 1 stabilised and 1 progressed. Clinically noteworthy toxicity was observed in one patient only.

Abstract
An early diagnosis in asymptomatic patients and a prompt treatment lead to an improved survival rate in patients with carcinoma of the colon. Patients with a short symptomatic history of colon cancer do not have a better prognosis than patients with a long history. Between 1978 and 1984 a consecutive series of 571 patients with colorectal cancer were admitted to the First Department of Surgery of the University of Rome. All patients were classified into five groups according to the duration of specific intestinal symptoms. In Group 1 (51 cases) asymptomatic patients were included, or patients with no specific symptoms such as asthenia, anemia, occult fecal blood. In Group 2 there were 129 patients with intestinal symptoms of less than 3 months' duration before treatment. In Group 3 there were 192 patients with symptoms of between 4 and 6 months' duration; 151 patients with symptoms of between 6 and 12 months were included in Group 4, and finally 48 patients who presented with symptoms of more than 1 year were included in Group 5. No relationship was noted between tumor site and duration of symptoms. Similarly, no relationship was noted between the duration of intestinal symptoms and stage and tumor differentiation. On the other hand, asymptomatic patients showed a higher incidence of T1N0M0 stage tumor and a lower percentage of undifferentiated neoplasms. The resectability rate was 79% and it was significantly related to the absence of intestinal symptoms. Follow-up data were available in 454 patients (80%). The overall survival rate was 52.4%. In Group 1 through Group 5 the 5-year survival rate was: 83.7%, 50%, 50%, 46.3%, 46.9%. The results of our study indicate that patients admitted in asymptomatic phase presented less-advanced stage tumors and, thus, best survival rate. On the other hand, from our data the duration of intestinal symptoms is not related to the stage and prognosis of tumors.

Abstract
Colorectal cancer is rare in patients under 40 years of age. We reviewed all colorectal cancer patients treated at the First Department of Surgery of the University of Rome, to determine the true incidence of large bowel cancer in young patients. During the period 1978-1984 a total of 571 patients were indexed. Out of these 44 were 39 years of age or less. A group of 527 patients 40 years of age or over served as a control. Neoplasms were localized in the right colon in 19 cases and in the left colon in 25 patients, in the young group. In the control group 178 patients presented neoplasms localized in the right colon, while 349 presented tumors localized in the left colon. According to tumor advancement in the young group tumor classification from A stage tumor through D stage was: 4, 6, 14, 5, 9, 6. In the control group 22 patients presented A stage tumors, 106 B1, 139 B2, 50 C1, 118 C2, 92 D tumors. The operability rate was 93.2% in the young group, and 92% in the old one. The operative mortality rate was 0% in the young group, and 2.5% in the old one. Four complications occurred in the young patients, and 57 in the old patients. The five years survival rate was 56.7% and 52.1% in young and old patients respectively. The results of our study indicate that there are no significant differences in prognosis and five years survival in young patients with colorectal cancer.

Abstract
Between 1976 and 1986, a consecutive series of 195 patients with right colon cancer were admitted at the First Department of Surgery of the University of Rome. Patients were divided into five groups according to the absence of intestinal symptoms (group 1) and the duration of the symptomatic phase (groups 2-5). Analysis of the preoperative investigation showed that colonoscopy was able to identify 33 (26.2%) of tumors misdiagnosed by double contrast X-ray barium enema. We did not notice any correlation among symptom duration and tumor stage, tumor differentiation, operability rate, and survival. Patients admitted in the asymptomatic phase presented tumors of less advanced stage and, thus, had the best survival rate (71.4%). In this group, patients promptly treated had a better survival rate (87.5%) than those treated after 2 months (50%). Our study suggests that only neoplasms diagnosed in asymptomatic patients and treated promptly are related to a good survival rate. We, therefore, emphasize the importance of education of patients and family physicians about right colon cancer and the necessity to investigate all patients with a suspected right colon cancer by means of colonoscopy.

Abstract
Thirty-four patients with metachronous colorectal cancer who underwent surgical procedures at the First and Fourth Department of Surgery of the University of Rome were reviewed. 55.9% of the patients developed a second carcinoma within five years after the first operation, and the time interval for the entire group ranged from 13 to 228 months. Adenomatous polyps occurred in 14 patients. Two patients developed a third metachronous cancer. We followed up eight patients using colonoscopy regularly. In this group we found two early cancers, five submucosal cancers and only one advanced tumor. In the other group we found 16 advanced cancers and ten submucosal cancer. The curability rate at second operation was 88.2%, and at the third 50%. The management of metachronous tumors should imply total colonoscopy, at a mean interval of 12-18 months.
