The rate of occurrence of postoperative hyperbilirubinemia (PHB) following esophagectomy for thoracic esophageal cancer was 67%, 115/171 cases, which was significantly higher than those following total gastrectomy (28%, 40/144 cases) and colectomy (12%, 7/59 cases). Among the operative procedures, right thoracotomy with extensive lymphoadenectomy had the highest rate of PHB (87%), perhaps due to the longest operation time and the largest intraoperative blood loss. Preoperative risk factors were glucose intolerance, reduced lymphocyte count, and poor nutritional state. The change in bile acid composition, as well as the elevation of alkaline phosphatase and gamma-glutamyl transpeptidase, indicated the presence of postoperative cholestasis which was relevant to total parenteral nutrition. The results suggest that the development of PHB was related to the extent of surgery and the use of parenteral nutrition.

Fusarium moniliforme has been associated with several diseases including equine leukoencephalomalacia, human esophageal cancer and hepatotoxicity/hepatocarcinogenicity in laboratory animals. The potential health risks to animals and humans posed by F. moniliforme contaminated grains cannot be assessed until the toxins are identified and toxicologically evaluated. As part of a systematic approach to identifying the hepatotoxins produced by F. moniliforme, diets containing aqueous and chloroform/methanol (1:1) extracts of F. moniliforme strain MRC 826 culture material (CM) and/or the extracted CM residues were fed to male Sprague-Dawley rats for four weeks. Serum alanine aminotransferase, aspartate amino-transferase and alkaline phosphatase activities were increased after two and four weeks and microscopic liver lesions were found in those animals fed aqueous CM extract and the CM residue after chloroform/methanol extraction. Fumonisins B1 and B2 were extracted from the CM by water, but not chloroform/methanol, and were present in the toxic diets at concentrations of 93-139 and 82-147 ppm, respectively. Nontoxic diets contained less than or equal to 22 ppm fumonisin B1 and less than or equal to 65 ppm fumonisin B2.

Minimal residual disease in patients with operable esophageal cancer is frequently missed by current noninvasive tumor staging. Here we applied an immunocytochemical cytokeratin assay that allows identification of individual esophageal carcinoma cells disseminated to bone marrow. Prior to therapy, bone marrow was aspirated from the upper iliac crest of 71 patients with esophageal cancer at various disease stages as well as an age-matched control group of 20 noncarcinoma patients. Tumor cells in cytologic bone marrow preparations were detected with monoclonal antibodies (mAbs) CK2, KL1, and A45-B/B3 to epithelial cytokeratins (CKs) using the alkaline phosphatase antialkaline phosphatase method. CK-positive cells were found in 14 (36.8%) of 38 cancer patients treated with curative intent and 16 (48.5%) of 33 patients with extended disease. The overall frequency of these cells was 1 per 4 x 10(5) to 82 per 4 x 10(5) mononuclear cells with no significant differences between patients at different tumor stages. After a short median follow-up of 9.5 months (3-24 months), 7 of 11 patients who underwent complete surgical resection but had tumor cells in bone marrow presented with tumor relapse compared to 2 of 19 corresponding patients without such cells (p < 0.01). It was concluded that although bone marrow is not a preferential site of overt metastasis of esophageal cancer, the frequent occurrence of isolated tumor cells at this distant site indicates that hematogenous dissemination of viable malignant cells occurs early in tumor progression.

Esophagitis is a major limiting factor in the treatment of lung cancer by radiation alone or in combination with chemotherapy. We have previously demonstrated that intraesophageal injection of manganese superoxide dismutase-plasmid/liposome (MnSOD-PL) complex into C3H/HeNsd mice blocks irradiation-induced esophagitis. To determine whether the human esophagus can be similarly transfected, normal human esophageal sections obtained from the margins of esophagectomy specimens from esophageal cancer patients were transfected in vitro with alkaline phosphatase (AlkP)-PL complex and stained for AlkP activity, and the percent of cells expressing AlkP was calculated. At 24 hr after transfection with 20 or 200 microgram of AlkP-PL complex, 55.0% and 85.8% of esophageal epithelial cells expressed detectable AlkP, respectively. Other sections transfected with MnSOD-PL complex showed transgene mRNA by nested reverse transcriptase-polymerase chain reaction (RT-PCR) assay and increased MnSOD biochemical activity for at least 96 hr after transfection. Irradiated MnSOD-PL complex-transfected sections demonstrated a significantly decreased percentage of apoptotic cells when compared to irradiated control sections. Following 1,000 cGy, MnSOD-PL-treated samples showed 7.5 +/- 2.8% and 33.3 +/- 7.3% apoptotic cells at 24 and 48 hr compared to 53.6 +/- 6.9% and 59.0 +/- 13.8% for nontransfected controls (P < 0.0001 and P < 0.1175). After 2,000 cGy, results at 24 and 48 hr were 25.0 +/- 7.6% and 66.9 +/- 4.9% for MnSOD-transfected sections compared to 65.6 +/- 4.3% and 90.0 +/- 4.1% for control sections (P < 0.0001 and P = 0.0353), respectively. Thus, human esophageal sections can be transfected with MnSOD-PL complex in vitro and thereby protected against ionizing irradiation-induced apoptosis. Int. J. Cancer (Radiat. Oncol. Invest.) 90, 128-137 (2000).

We have retrospectively evaluated clinical data before therapy to enable reliable prediction of the response of esophageal cancer to chemoradiotherapy (CRT). We analyzed 108 patients who received 5-fluorouracil and platinum combined with 60 Gy radiation for esophageal cancer. Factors significantly related to response were extracted by use of logistic regression analysis, and a response score (RS) was prepared by combining these factors. By multivariate analysis, nutritional status, T stage, M stage, and alkaline phosphatase were selected as significant factors that contributed independently to the response of esophageal cancer to CRT (P < 0.05). The odds ratios of the four selected factors was approximated and scored. The group with a high RS was found to include patients with complete response with a significantly higher frequency than the group with a low score (72.7% vs. 14.8%, P < 0.001). The RS is suggested to be an appropriate scoring system with which to predict response for these patients.

Oesophageal cancer is endemic in some regions of the Islamic Republic of Iran and efforts have made to find factors that play a role in its prognosis. We retrospectively examined the correlation of serum alkaline phosphatase (ALP) levels with several clinicopathological characteristics of 207 cases of oesophageal carcinoma. The mean ALP level in patients with lymph node involvement was significantly higher [141 (SD 77) U/L] than with node negative cancers [116 (SD 63) U/L]. Patients with ALP levels 165 U/L were 3.29 times more likely to have lymph node involvement than patients with ALP levels < or = 165 U/L. There was no statistically significant correlation between ALP level and sex, age, tumour histological type, site and size of tumour, depth of penetration, distant metastasis, degree of differentiation, presence of lymphatic invasion and presence of simultaneous multiple cancers. Elevated ALP in patients with oesophageal cancer may predict lymph node involvement.
