Liver metastases of colorectal cancer is present in more than 20% of new diagnosed patients and in 40-60% of relapsed patients. It is a life-threatening prognostic aspect. Hepatic resection, when possible, is the best therapeutic modality, although the overall survival rate is still low (30%). Angiography and intraoperative ultrasonography are useful for resection. The number of hepatic metastases and the surgical margin are probably the most significant prognostic factors. Colorectal cancer may spread predominantly to the liver making regional treatment strategies viable options. Subtotal hepatic resections and segmentectomies are potentially curable procedures for single or small numbers of hepatic metastases without other sites of disease. However, there have been no prospective randomized trials comparing patients with unresected liver metastases and resected metastases. Regional chemotherapy with floxuridine seems usefull combined with hepatic resection or as palliative therapy. Gastric ulcer and biliary sclerosis are the main related toxicities. Patients with localized, unresectable hepatic metastases or concomitant bad medical condition may be candidates for radiation, percutaneous ethanol injection, cryosurgery, percutaneous radiofrequency, hypoxic flow-stop perfusions with bioreductive alkylating agents, hepatic arterial ligation, embolization and chemoembolization. These new hepatic-directed modalities of treatment are being investigated and may offer new approaches to providing palliation and prolonging survival. This review will report the possibilities of intra-arterial chemotherapy and other novel hepatic-directed approaches to the treatment of liver metastases from colorectal cancer.

Liver metastasis of colorectal cancer is a life-threatening prognostic factor. Hepatic resection, when possible, is the best therapeutic modality, although the overall survival rate is still low (30%). The diagnosis has been carried out by clinical examination, abnormal alkaline phosphatase, lactic acid dehydrogenase and tumor markers, abdominal liver echography and computed tomography scan. Angiography and intraoperative echography are useful for resection. The number of hepatic metastases and the surgical margin are probably the most significant prognostic factors. Colorectal cancer may spread predominantly to the liver making regional treatment strategies viable options. Subtotal hepatic resections and segmentectomies are potentially curable procedures for single or small numbers of hepatic metastases without other sites of disease. However, there have been no prospective randomized trials comparing patients with unresected liver metastases and resected metastases. Regional chemotherapy with floxuridine seems useful combined with hepatic resection or as palliative therapy. Gastric ulcer and biliary sclerosis are the main related toxicities.

These new hepatic-directed modalities of treatment are being investigated and may offer new approaches to providing palliation and prolonging survival. This review reports the possibilities of intraarterial chemotherapy and other novel hepatic directed approaches to the treatment of liver metastases from this common disease.

A 69-year-old male presented with symptoms of fulminant lung embolism and, despite immediate therapy with plasminogen activator, died of acute right heart failure. At autopsy multiple tumor cell emboli were detected in small pulmonary vessels in addition to widespread liver metastases from an urothelial carcinoma. - In a 23-year-old female a malignant gastric ulcer and multiple liver metastases were diagnosed at initial presentation. She too died from pulmonary hypertension due to a series of lung embolisms which occurred despite heparin therapy. At autopsy, many small pulmonary arteries were filled with adenocarcinoma cells; the primary gastric tumor and liver metastases were confirmed. These cases demonstrate that the shedding of tumor cells from hepatic metastases can obstruct the pulmonary vessels and lead to acute cor pulmonale. Tumor cell emboli should be considered in the differential diagnosis of acute pulmonary hypertension, especially in patients with a known tumor. They may, however, also represent the first clinical signs of previously unrecognized malignancy.

A 74-year-old man was admitted because of appetite loss in November 1999. A gastric ulcer was diagnosed, and a H2 blocker was given. He had had appetite loss since July 1997 and had experienced epigastric discomfort since October of 1997. On admission, hepatic and pancreatic lymph node swelling was detected by ultrasonography of the abdomen. Physical examination revealed a palpable mass in the middle region of the upper abdomen as well as gynecomastia. Laboratory findings showed high serum levels of hCG (11,700 mIU/ml) and high urinary levels of hCG (1,600 mIU/ml). Upper gastrointestinal endoscopy showed a gastric cancer of Borrmann type 3 in the posterior wall of the middle body. A biopsy revealed a moderately differentiated adenocarcinoma. hCG immunoreactivity was not seen in the cancer tissue. A contrast-enhanced CT scan of the abdomen revealed multiple lymph node swelling in the hepatic and pancreatic lymph nodes. There was a low-density area suggesting liver metastases. No other primary carcinomas were not detected. We believe that the gynecomastia was due to the hCG-producing tumor. The patient died 2 months after diagnosis.

We report the case of a 77-year-old man who developed low grade B cell non-Hodgkin's lymphoma of the gastric stump 5 years after undergoing a distal gastrectomy for benign gastric ulcer. Lymphoma occurring in the post-operative stomach would appear to be very rare, with only 14 previously recorded cases. The median period of lymphoma onset after ulcer surgery is about 20 years (range 9-43 years) and gastric remnants of lymphoma are generally diagnosed in low stage, when surgery is possible and makes the prognosis good. The clinical case presented herein is quite different from the others. The patient developed lymphoma within 5 years of the ulcer surgery, thus, earlier than generally reported in literature; he presented with massive regional and extra-regional nodes involvement and liver metastases and he poorly responded to antiblastic chemotherapy. The pathogenetic role of Helicobacter pylori (HP) infection and the possibility of malignant lymphoma developing in the gastric stump are discussed.

Since two decades transarterial chemoembolization (TACE) of liver metastases has been investigated in numerous studies. However, no standardized therapeutic procedure exists so far. The present study retrospectively investigated survival, response and side effects after TACE of liver metastases in 21 patients with colorectal cancer and results are compared with previous literature. A total of 68 TACE procedures were performed. A suspension of degradable starch microspheres (DSM, Spherex) and Mitomycin C was applied selectively into hepatic arteries via a transfemoral approach. DSM effect a temporary arterial occlusion. Follow-up studies were performed by contrast enhanced spiral computed tomography (CT). The median survival was 13.8 months. Therapeutic response (according to WHO) was observed only in three patients. The progression free interval was 5.8 months. Patients developed a postembolization-syndrome (abdominal pain, fever, nausea) and increased transaminases in 27-43% of all interventions. A gastric ulcer occurred after four, cholecystitis after two TACE. As already shown in most previous studies, regardless of the used agents, also this investigation underlines the moderate therapeutic effect of TACE on colorectal liver metastases. So far, no significant survival benefit has been shown in the literature and the response rates are rather limited. In general, complications of TACE seem to be rare, but should not to be underestimated. Compared to TACE with long or permanent arterial occlusion, postembolization syndrome seems to be less pronounced using DSM. As TACE is rather a palliative therapeutic approach, DSM therefore might be more suited. Further studies on TACE of liver metastases should focus on to the patients' quality of life.

Malignant melanoma involving the gastrointestinal tract is diagnosed antemortem in only a small percentage of patients with the disease. Presenting symptoms are often non-specific, causing a diagnostic problem. The vast majority of such melanomas are metastatic from a cutaneous primary, however there is evidence that the tumour can arise de novo in the gastrointestinal system. We report a 74-year-old man with malignant melanoma with an unusual presentation simulating a symptomatic gastric ulcer. He presented with epigastric pain, haematemesis and melaena. Explorative laparotomy revealed a large ulcerated tumour with several pigmented satellite nodules in the proximal stomach, multiple ileal nodules and widespread nodal and liver metastases. Proximal gastrectomy and limited small bowel resection was performed. Histology revealed the tumour to be composed of nests of epithelioid cells with melanin pigment. The tumour cells showed immunohistochemical positivity for S100 protein and HMB45 antibodies. This report emphasizes that melanoma should be a diagnostic consideration in patients with gastric ulcer.

Malignant degeneration is the most serious complication of gastric ulcer. Its recognition is difficult both in the early stage and in advanced cases in which only the evidence of a previous ulcer-cavity, and the radiating folds of the mucous membrane indicate progressive development of carcinoma from an original ulcer.It is impossible to say how often gastric ulcer becomes malignant; one can only state the frequency of ulcer-carcinoma, found in gastric resections.One hundred and forty-one personal cases of ulcer-carcinoma are recorded, and are divided into three groups.GROUP I: 41 which were diagnosed clinically and at operation as cases of ulcer, but in which histological examination showed incipient cancer.GROUP II: 55 diagnosed clinically as cases of ulcer, but in which a diagnosis of ulcer-carcinoma was made during operation and afterwards histologically confirmed.GROUP III: 45 diagnosed both clinically and macroscopically (from the typical folding of the mucous membrane) as cases of ulcer-cancer, in which the cancer had entirely overgrown the ulcer.Therefore in the series of 532 resections for gastric ulcer the frequency of ulcer-carcinoma was 20.9%, or 15.2% if the third group is omitted.In a series of 718 resections for gastric cancer, the frequency of ulcer-carcinoma was 19.6% (or 14.2% if the third group is omitted).The mortality in simple two-third resection of the stomach is low (four deaths in 99 cases = 4%). When the pancreas, liver, colon, or oesophagus, is involved, the resection mortality is high (14 deaths in 42 cases = 33.3%), but even in these cases the operation is justifiable because permanent cures were achieved in a number of cases.The prognosis in cases of ulcer-cancer is very grave. In many cases, judging from the author's own experience, patients suffering from incipient ulcer-cancer-only histologically diagnosed as cancer-die from liver metastases, in spite of radical resection. It will thus be seen that the end-results of resection for ulcer-carcinoma are actually worse than those of resection for primary carcinoma.A. Ulcer-cancer: In Group I, 35 cases were operated on before 1933, and in 18 of these (51.4%) the patients have been free from symptoms for more than five years; in Group II, 27 cases were operated on before 1933, and in four of these (14.8%) the patients are still symptom-free. In Group III, out of 37 cases operated on, only two patients (5.4%) have been symptom-free for the same period.B. Primary cancer: Out of 260 cases of resection for primary cancer before 1933, 77 patients (29.6%) are permanently cured.If the ulcer-cancer is so far advanced that the diagnosis can be made clinically, or during operation, the prognosis is extremely bad (permanent cures having been only 9.3% in the series).In cases of gastric ulcer the best plan is to carry out resection before malignant degeneration begins. The result would then be that not merely 51% but at least 90% of the patients would be alive and well after five years.

The liver is the predominant site of metastases in the majority of patients with uveal melanoma, suggesting the evaluation of regional treatment approaches. Here we report our experience with transarterial chemoembolization (TACE) in uveal melanoma patients with pretreated liver metastases. Twenty-five patients were treated with fotemustine-based or cisplatin-based TACE after treatment failure of systemic therapy between 2003 and 2008 at our institution. Grade III toxicity consisted of gastric ulcer (n=1), fever (n=3), splenic infarction (n=1), and thrombocytopenia (n=1). No grade IV toxicity or catheter-associated complications were observed. Fourteen of 25 patients (56%) had stable disease for at least 2 months and four had partial remission. The median progression-free survival (PFS) was 3 months (95% confidence interval: 2-4 months) and the median overall survival (OS) was 6 months (95% confidence interval: 5-7 months), with 15% of patients alive at 1 year. Both PFS and OS were significantly longer, when pretreatment lactate dehydrogenase was below the two-fold upper limit of normal (n=11): PFS 5 versus 2 months (P<0.001) and OS 11 versus 5 months (P=0.012). All patients with lactate dehydrogenase less than 2xupper limit of normal had a clinically detectable benefit. TACE is well tolerated and effective in pretreated patients with liver metastases from uveal melanoma. TACE should further be evaluated as first-line therapy in prospective randomized clinical trials.
