We reported a rare case of malignant lymphoma, highly suspected to be of pancreas origin with multiple nodular hepatic invasions. A 63-year-old man visited our hospital on May 24 1990, complaining of anorexia. In spite of high serum levels of LDH and amylase, abdominal ultrasonography (US) showed no significant lesions. Forty days later, he was admitted because of the loss of weight and the appearance of abdominal pain with marked hepatomegaly, exhibiting cachexia. Abdominal US and computed tomography visualized a tumor of pancreas with multiple nodular space-occupying lesions in the liver. In several days, jaundice and ascites appeared with progressive deterioration. Angiography showed no tumor vascularity nor vascular stain in pancreas and liver, suggesting a non-epithelial malignancy. Mitomycin C and Epi-adriamycin, given to the patient via the celiac artery, brought about a remarkable shrinkage of the abdominal tumor. Subsequent systemic chemotherapies and occasional intra-arterial chemotherapies resulted in the disappearance of abdominal tumor clinically. However, at the end of April 1991, signs of CNS involvement were observed, and he died on June 7, 1991. Autopsy revealed that malignant lymphoma, of diffuse large cell type, had invaded the subarachnoidal cavity without any evidence of invasion of the abdomen or other sites except regional necrotic lesion in the pancreas. These findings strongly suggested that the patient suffered from malignant lymphoma of pancreas origin with multiple nodular hepatic invasions.

Mucinous peritoneal carcinomatosis from a primary gastrointestinal malignancy is a lethal condition that has few treatment options with the use of surgery, chemotherapy or radiation therapy. Recent advances in hyperthermia technology and in knowledge of the natural history of this disease has suggested the possible utility of hyperthermia in the application of aggressive local-regional therapy. Radiofrequency (RF) hyperthermia to the whole abdomen, to the hemithorax, or to an isolated mucinous tumour deposit obstructing the gastrointestinal tract was used in patients with disseminated mucinous adenocarcinoma of appendiceal origin. There were 228 hyperthermia treatments in 21 patients, with a median of 10 treatments per patient. The maximum number of treatments was 26, and minimum was one. For the first six hyperthermia treatments, escalating doses of deep hyperthermia (41-45 degrees C) was monitored with multiple sensor internal temperature probes and a single sensor subcutaneous temperature probe. After reaching a maximal hyperthermia treatment, this was maintained for all subsequent treatments. Initially, the maximal temperature allowed in tumour and subcutaneous tissue was 43 degrees C. After 50 hyperthermia treatments, this was changed to 45 degrees C. If disease stabilization or response was insufficient and maximal tolerable hyperthermia had been established, the frequency of treatment was increased from every 4 weeks to every 2 weeks, and escalating doses of mitomycin C at 8 mg/m2 were added to the regimen. Mitomycin C was infused during the hyperthermia treatment. For the first 165 treatments, patients were monitored just before and 10 days after hyperthermia with a complete blood count and a full battery of laboratory tests including amylase and lipase. Response was monitored by carcinoembryonic antigen assays on a monthly basis and CT scans on a 6 monthly basis. None of the 21 patients included in this study died, required intensive care, or required major surgical interventions as a result of hyperthermia treatments. One potentially life-endangering event was profound bradycardia and hypotension observed in a 76-year-old male receiving hyperthermia treatment to his right hemithorax. Two patients developed an enterocutaneous fistula (a frequent spontaneous event in this group of patients) while under treatment. No abnormal laboratory tests were observed in the first 165 hyperthermia treatments. Heat damage to normal tissue was limited to skin blisters in three patients and induration of the subcutaneous tissues in 10 patients. Skin pain on an analogue scale of 0-10 was scored by patients as a mean of 3.6 (range 0-8) before skin analgesia was routinely utilized. With anesthetic gel, the skin discomfort was greatly reduced. Prolonged abdominal pain for 4-20 days following treatment which required narcotic analgesia was seen in four patients. A complication rate of 62% was caused by the long-term indwelling temperature probe sheaths. Infection was observed in four patients, small bowel fistula in one, and dislodgement of the temperature probe sheath requiring repeat CT was necessary in seven patients. After maximal escalation of RF power in seven patients (33%), deep hyperthermia compatible with thermal destruction of tumour (> or = 43 degrees C for 45 min) was recorded in all subsequent treatments. In eight patients (38%), heat generation compatible with chemotherapy augmentation (41.5-43 degrees C) was consistently recorded. In six patients, non-therapeutic temperatures were recorded. There was no correlation of maximal tumour temperature, maximal subcutaneous tissue temperature and maximal RF power. With the use of skin anaesthetic there was no correlation of tumour temperature and the thickness of the subcutaneous layer of the skin. Progression was seen in 14 patients, and 11 of these patients died. No patients who showed disease stabilization have died with a minimum of 2 year follow-up. (ABSTRACT TRUNCATED)

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.

13 patients affected by multifocal and/or large liver metastases from various solid tumors have been treated with stop-flow liver perfusion, to evaluate the safety and feasibility of hypoxic loco-regional infusion with Mitomycin C. The treatment was based on the hypoxic effect due to stop-flow, potentiating the cytotoxic activity of Mitomycin C, combined with the ischemic damage caused by the embolization of the vascular supply to the tumor. The schedule consisted in blocking arterial flow by an angiographic occlusion balloon catheter inflated in the hepatic artery, with previous placement of a vascular stent in order to prevent iatrogenic arterial lesions, and followed by the intraarterial administration of Mitomycin C; finally, arterial hepatic embolization was performed by a gelatine sponge. The study is ongoing with a median follow up of 8 months (range 2-12). Partial response was observed in 1/13 patients (8%), stable disease in 8/13 patients (61%), while progressive disease occurred in 4/13 patients (31%). Nine patients are still alive, and four patients died for hepatic progressive disease, three of them heavily pre-treated with multiple lines of chemotherapy for advanced disease. Toxicity was mild; main side effects were anaemia and thrombocytopenia(Grade 3 both in 1/15 treatments), while fever, nausea and vomiting and upper abdominal pain were short-lasting and easily manageable. No iatrogenic lesion of the hepatic arterial wall occurred. These preliminary data, although the small number of patients and the short follow up, show that the procedure is safe and feasible, with a interesting percentage of clinical responses. In addition, the placement of an arterial stent have demonstrated to protect vascular wall ensuring a regular blood flow, so allowing to perform repeated treatments in responsive patients. The good tolerability of this therapeutic modality suggests further investigation in order to determine its efficacy even in combination with systemic chemotherapy and other locoregional treatments such as termoablative procedures and/or intraarterial antiblastic perfusions in patients affected by metastatic liver disease.
