A clinical assessment of fungal infection in hepatobiliary and pancreatic diseases during 1975 and 1991 was made and 25 cases of systemic mycosis were noted. Among 25 cases there were 20 liver diseases (hepatocellular carcinoma 12, liver cirrhosis 5, fulminant hepatitis 2, polyarteritis nodosa 1), 2 cases of gallbladder cancer and 3 cases of pancreatic cancer. The fungus was consisted of 14 cases (56%) of Candida, 9 cases of Aspergillus (36%), and 2 cases of Cryptococcus (8%). Fungal infection was most frequent in the lung (8 cases) and esophagus (6 cases), but rarely in the stomach, lymph node, liver, thyroid, kidney and gallbladder. Generalized fungus infection was noted in four cases (16%). Fatal fungal infection was complicated in liver cirrhosis (2 cases), fulminant hepatitis (one case), gallbladder cancer (one case) and cystadenocarcinoma of the pancreas (one case). In five fatal cases three cases of Aspergillus pneumonia and two cases of Candida septicemia were included. Glucocorticoid was used in 13 cases (52%) and anti-cancer drugs was administered in two cases (12%). However, in 9 cases (36%) without treatment of glucocorticoid or anti-cancer drug fungal infection was detected. In conclusion, there is a possibility of fungal infection in grave hepatic diseases and empirical administration of anti-fungal agent may be necessary.

Phospholipase A2 (EC 3.1.1.4; PLA2) is detected in serum by determination of either the catalytic activity of the enzyme or the concentration of the enzyme protein by immunoassays. The most sensitive methods for determining PLA2 catalytic activity are radiometric assays, with a substrate of synthetic phospholipid (e.g., phosphatidylcholine or phosphatidylethanolamine) containing a 14C- or 3H-labeled fatty acid at the sn-2-position. Membranes of autoclaved Escherichia coli grown in the presence of radioactive oleic acid may also be used as a substrate. The released fatty acids are separated from the unreacted substrate and quantified by liquid scintillation counting. PLA2 catalytic activities are increased in serum in sepsis, acute pancreatitis, peritonitis, multiple injuries, rheumatoid arthritis, and other arthropathies. Immunoassays--radioimmunoassay, enzyme-linked immunosorbent assay, or time-resolved fluoroimmunoassay--are based on the use of either polyclonal or monoclonal antibodies to purified PLA2s. Specific assays have been developed for both pancreatic group I PLA2 (PLA2-I) and nonpancreatic group II PLA2 (PLA2-II). The cellular source of PLA2-I in serum is the pancreatic acinar cell. Increased serum PLA2-I values have been reported in acute pancreatitis, pancreatic cancer, and abdominal trauma. Increased PLA2-II values are found in conditions involving inflammation, e.g., sepsis, infections, acute pancreatitis, various forms of arthritis, cancer, complications of pregnancy, and postoperative states. Good correlations have been found in serum samples between the catalytic activity of PLA2 and the concentration of PLA2-II but not PLA2-I. PLA2-II may represent an acute-phase protein. The cellular source of the PLA2-II in serum is unknown; it is present in large amounts in cartilage and Paneth cells, prostatic gland cells, seminal fluid, lacrimal gland cells, and tears, but cannot be demonstrated by immunohistochemical or immunochemical methods in inflammatory cells.

Carcinomas of the exocrine pancreas respond poorly to most chemotherapy regimens. Recently continuous infusional 5-fluorouracil (200 mg m-(2)day-1) with 3 weekly cisplatin (60 mg m-2) and epirubicin (50 mg m-2) (the ECF regimen) has proven to be an active regimen in gastric and breast cancer and consequently worthy of further study in pancreatic cancer. Thirty-five patients were treated with the ECF regimen as above, of whom 29 were evaluable for response and 32 were evaluable for toxicity. The mean age was 59 years (range 37-75). Sixteen patients had locally advanced disease at presentation and 19 had metastases. Objective tumour responses were documented in five (17.3%) patients who achieved a partial response; in 18 (62%) patients there were no change and six (20.7%) patients progressed on therapy. Patients with either stable disease or partial response had a significantly improved overall survival (median = 253 days) compared with patients who progressed (median = 170 days; P = 0.01). Grade 3/4 (WHO) toxicity (all cycles) included alopecia in 18 (56%) patients, nausea/vomiting in eight (25%) stomatitis in three (9%) and diarrhoea in seven (22%) patients, with rhinorrhoea and excessive lacrimation in one patient each. Neutropenic sepsis occurred in 13 cycles in ten patients, and there was one toxic death due to sepsis. There were eight other episodes of non-neutropenic sepsis requiring hospital admission. Fourteen patients (40%) experienced complications with their Hickman lines, including thrombotic episodes (six patients) or their line falling out (five patients). ECF can prolong survival in patients with locally advanced or metastatic pancreatic cancer who demonstrate a response or stabilisation of their disease. However, this is associated with considerable toxicity.

We have performed combined chemotherapy with 5-FU, a biochemical modulator, and low dose CDDP for advanced or recurrent cancer of the digestive system. The therapy was effective in 37% of all cases and in 45.5% and 41.6% of esophageal and gastric cancer cases, respectively. In addition, few patients developed adverse side effects including renal disorders, one of the major side effects of CDDP. Therefore, we considered home anti-cancer chemotherapy feasible. For 27 outpatients with advanced cancer of the digestive system including 15 cases of esophageal cancer, 4 cases of gastric cancer, 3 cases of colon cancer, 4 cases of pancreatic cancer and 1 case of gall bladder cancer, 4 to 6 week home adjuvant chemotherapy was performed. The regimen comprised 1 week of oral administration of 300 mg/body/day of UFT-E granules and 5 days of continuous intravenous infusion of 25 mg/body/day of CDDP using an infusor pump. During the follow-up, 3 cases of catheter obstruction, 3 cases of catheter sepsis and 1 case of pneumothorax appeared. These complications all resulted from the catheter, and safe home anti-cancer chemotherapy could be continued because 5-FU and CDDP did not cause severe side effects.

The incidence of bacteria caused postoperative infections was performed at the timing when bacteria or fungi is not yet detected. This period is important for management of postoperative infections. MRSA, E. faecalis, P. aeruginosa and fungi were detected with high frequency irrespective of the surgical area. After the operation of esophageal cancer, the most frequent infection was postoperative pneumonia, and the isolated bacteria was P. aeruginosa frequently. In the cases of gastric cancer, hepato-biliary-pancreas cancer and colorectal cancer, intraabdominal sepsis was the highest incidence, and the isolated bacteria was E. faecalis. In terms of intravenous catheter infection, fungus was common. Thus, it may suggest that we can identify the bacteria caused, and the management for postoperative infections was performed appropriately by using the antibiotics which have the sensitive against the expected pathogen.

An effective local-regional therapy is needed for adenocarcinomas of the pancreas. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton NJ) may enhance the effect of radiation therapy. Paclitaxel synchronizes cells at G2/M, a relatively radiosensitive phase of the cell cycle. We have shown that response to paclitaxel and concurrent radiation (paclitaxel/RT) was not affected by p53 mutations in non-small cell lung cancer (NSCLC). This suggested that paclitaxel/RT was a rationale treatment approach for other malignancies which frequently harbor p53 mutations such as upper gastrointestinal malignancies. We have completed a phase I study of paclitaxel/RT for locally advanced pancreatic and gastric cancers. The maximum tolerated dose (MTD) of paclitaxel was 50 mg/m2/week for 6 weeks with abdominal radiation. The dose limiting toxicities were abdominal pain within the radiation field, nausea and anorexia. Twenty-five patients with locally advanced pancreatic cancer have now completed treatment at the phase II dose level of paclitaxel 50 mg/m2/week with 50 Gy concurrent RT. Thus far, the only grade 3/4 toxicities have been hypersensitivity reactions in 2 patients, asymptomatic grade 4 neutropenia in 3 patients, and non-neutropenic biliary sepsis in 1 patient. Of the first 22 assessable patients treated at the phase II study, 8 obtained a partial response (PR) for a preliminary response rate of 36%. These findings demonstrate that paclitaxel/RT is well tolerated with substantial activity for locally advanced pancreatic cancer.

An effective locoregional therapy is needed for adenocarcinomas of the pancreas, stomach, and gastroesophageal junction. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) may enhance the effect of radiation therapy (RT). Paclitaxel synchronizes cells at G2/M, a relatively radiosensitive phase of the cell cycle. We have shown that response to paclitaxel and concurrent RT (paclitaxel/RT) was not affected by p53 mutations in non-small cell lung cancer. This finding suggested that paclitaxel/RT was a rational treatment approach for other malignancies that frequently harbor p53 mutations, such as upper gastrointestinal malignancies. We completed a phase I study of paclitaxel/RT for locally advanced pancreatic and gastric cancer. The maximum tolerated dose of paclitaxel was 50 mg/m2/wk for 6 weeks with abdominal RT. The dose-limiting toxicities were abdominal pain within the radiation field, nausea, and anorexia. Phase II studies are now under way. Twenty-five patients with locally advanced pancreatic cancer have been entered at the phase II dose level of paclitaxel 50 mg/m2/wk with concurrent RT (total dose, 50 Gy). Thus far, the only grade 3/4 toxicities have been hypersensitivity reactions (n = 2), asymptomatic grade 4 neutropenia (n = 3), and nonneutropenic biliary sepsis (n = 1). Of the first 18 assessable patients with pancreatic cancer treated on the phase II study, six obtained a partial response, for a preliminary response rate of 33%. In the phase II study for locally advanced gastric cancer, 20 patients have been enrolled. Of the first 19 patients who have completed treatment, nine (47%) had grade 3/4 toxicities, including nausea, anorexia, esophagitis, and gastritis. Of the first 16 patients with gastric cancer, complete and partial responses have been observed in one and eight patients, respectively, for a preliminary response rate of 56%. We have also completed treatment on 24 patients with potentially resectable adenocarcinomas of the gastroesophageal junction with neoadjuvant paclitaxel 60 mg/m2 and cisplatin 25 mg/m2, weekly for 4 weeks, with concurrent RT (total dose, 40 Gy) followed by surgical resection. Ten patients (41%) had grade 3/4 toxicities, including neutropenia, nausea, and dehydration. Of 24 patients, four complete responses (17%) and 14 partial responses (58%) were observed, for an overall response rate of 75%. Severe esophagitis was uncommon, making this a well-tolerated outpatient regimen for adenocarcinomas of the distal esophagus. These findings demonstrate that paclitaxel-based chemoradiation for locally advanced upper gastrointestinal malignancies is well-tolerated with substantial activity.

Seventy-three eligible, chemotherapy-naive, ambulatory patients with advanced pancreatic carcinoma were allocated to one of two treatment regimens: 35 received PALA (1250 mg/m2 daily x 5 every 4 weeks) and 38 were given SAM (streptozotocin 400 mg/m2 i.v. daily x 5, doxorubicin 45 mg/m2 i.v. on day 1 and 22, and methyl CCNU 60 mg/m2 orally on days 1 and 22 every 6 weeks). Doses were modified for myelo-, gi-, or cardiotoxicity. Adequate organ, bone marrow and cardiac function; a measurable lesion; adequate caloric intake; and a life expectancy of 2 months were required for treatment on this trial. One patient on each regimen had a partial response for response rates of 3% (95% confidence intervals, 0.08 to 17%). Median survival on the PALA arm was 5 months and median time to treatment failure was 2.6 months. SAM patients experienced median overall and progression free survivals of 3.4 and 1.9 months, respectively. The severe toxicity observed was almost exclusively myelosuppression on both regimens. One patient receiving SAM had lethal leukopenic sepsis during the first cycle as the only treatment-related death. Neither PALA nor SAM offer any therapeutic utility to patients with advanced pancreatic cancer.

Although pancreatectomy is still performed in a few patients with pancreatic cancer, and nearly all patients who develop pancreatic cancer eventually die of their disease, significant improvements have been made recently. Pancreatectomy is now safer, with major morbidity (hemorrhage, pancreatic anastomotic leak, intraabdominal sepsis) occurring in only about 20% and operative mortality of less than 5%. Two (seemingly subtle) issues cannot be overemphasized when someone carefully studies the literature: (1) There is a crucial difference between actuarial and actual survival, with the former generally being higher whereas the latter is true; and (2) careful re-review of pathologic specimens (especially in long-term survivors) initially diagnosed as pancreatic cancer, preferably by an independent pathologist before publishing long-term results is essential. (Erroneous inclusion of patients with nonductal carcinoma substantially and artificially increases survival.) After curative resection, 5-year actual survival is realistically about 10% with median survivals of 12 to 18 months. In certain subgroups with favorable pathologic characteristics (neoplasms <2 cm without nodal or perineural invasion) the prognosis appears to be significantly better, with the 5-year survival about 20%. The recent improvements in postoperative morbidity and mortality and long-term outcome (resulting also in decreased cost of care of such patients) have occurred typically in centers with an invested interest in and proven record with pancreatic surgery. Further improvements in survival should be sought at the areas of earlier diagnosis and novel treatments designed to prevent locoregional recurrences; the role of extended resections must be determined by prospective, randomized trials.

Acute liver failure (ALF) is a rare clinical syndrome associated with a mortality of up to 80% and its management remains an interdisciplinary challenge. Despite recent improvements in intensive care management, the mortality of patients with ALF remains high and is related to complications such as cerebral edema, sepsis and multiple organ failure. Emergency orthotopic liver transplantation (OLT) is currently the only effective treatment for those patients who are unlikely to recover spontaneously. Nevertheless, OLT is not always possible because of the shortage of the organs and/or complications related to ALF. Newly introduced liver-assist devices can temporarily support the patient's liver until native liver recovers or can serve as a bridging device until a liver graft is available. The support devices use both cell-based and non-cell-based techniques. One of the latest non-cell-based extracorporeal hepatic support devices, the molecular adsorbent recycling system (MARS), is based on the concept of albumin dialysis. MARS utilises selective hemodiafiltration with countercurrent albumin dialysis aiming to selectively remove both water-soluble and albumin-bound toxins of the low and middle molecular-weight range. We report on a young patient who presented with clinical symptoms of ischemic hepatitis and multi-organ failure (APACHE II score 38-->predicted postoperative mortality 87%) due to prolonged hemorrhagic shock. OLT was contraindicated because of history of pancreas cancer with metastases. It was necessary to use aggressive conservative therapy and an extracorporeal liver-assist device until liver regeneration began and hemodynamic conditions were stable. The patient underwent five treatments with MARS. During the treatment, there were improvements of hemodynamics, respiratory function, acid-base disturbances and laboratory parameters. The plasma disappearance rate of indocyanine green, a parameter of dynamic liver function, improved during MARS treatment. Although repeated neurological examination predicted diffuse brain damage (brain oedema, decreased cerebral blood flow), the patient recovered without any neurological deficits. The patient survived and was discharged from the hospital in good condition. In this case MARS treatment was successful in supporting the patient through the most critical period of ALF.
