We describe here a rare case of hepatoid adenocarcinoma (HAC) of the gallbladder without the production of alpha-fetoprotein (AFP). A 77-year-old man was referred to our division with complaints of general fatigue, loss of appetite, and loss of body weight. A preoperative diagnosis of advanced gallbladder cancer was made, and cholecystectomy with combined resection of two liver subsegments (S4a + S5) and lymph node dissection were performed. Microscopically, the tumor was mainly composed of characteristic cells featuring eosinophilic cytoplasm, enlarged nuclei, and prominent nucleoi, arranged in nests or proliferated in a trabecular pattern. These features were highly suggestive of HAC of the gallbladder, and the tumor cells were negative for AFP immunohistochemical staining. The patient is doing well and has survived for 15 months postoperatively without any recurrence.

A 91-year-old man was admitted with colliquative diarrhea, anorexia and weight loss. He had a history of healed tuberculosis, hypertension and atherosclerotic abdominal aortic aneurysms. On admission, shortness of breath without cough, exertional dyspnea, and ascites were also noticed. His chest X-ray and CT showed almost normal findings in the lung fields except for calcified old pleurisy. Since laboratory tests revealed thrombocytopenia, low fibrinogen, and increased CA19-9. DIC induced by an unknown cancer was diagnosed. He died on the eighth day due to progressive respiratory failure which did not respond to oxygen therapy. Autopsy revealed that he had a poorly differentiated adenocarcinoma in the cecum complicated with pulmonary lymphangitis carcinomatosa. Lymphangitis should be considered in the case of unexplained progressive respiratory failure developing in patient with cancer, even in the absence of X-ray findings.

A 69 years old female patient was admitted to the hospital with anemia, loss of appetite and weight since three months. The physical examination showed extended cutaneous bleedings. Laboratory tests revealed a hemolytic anemia with fragmented erythrocytes. The bone marrow examination was characterized by erythroid hyperplasia and an invasion by mucin-producing adenocarcinoma cells. Upper endoscopy detected a small hiatal hernia with mucosal erosions between esophagus and stomach. The histology of the mucosal biopsy identified a poorly differentiated mucin-producing adenocarcinoma with portions of signet-ring cells. X-ray examination revealed osteoplastic bone metastases of the vertebrae and of the pelvis. We diagnosed a disseminated, mucin-producing adenocarcinoma of the stomach, associated with microangiopathic hemolytic anemia. In spite of rapidly begun chemotherapy with adriamycin and daily blood transfusions the woman died after four weeks.

Mucinous adenocarcinoma of the appendix is rare. If there is a concomitant ovarian tumor to determine the primary might be difficult. Histological features are not always determinant, but there are some macroscopic findings that may suggest an origin in the appendix. We report a case of synchronous tumors in appendix and ovaries with pseudomyxoma peritonei. The patient presented with mass sensation in the right lower quadrant, asthenia, anorexia and weight loss. Abdominal ultrasound and CT scan showed a tumor involving cecum, appendix, terminal ileum and pelvis. Findings on colonoscopy and biopsies were inconclusive. At laparotomy, the tumor compressed appendix, cecum and ascendant colon, terminal ileum, ovaries and peritoneum. Histopathological analysis demonstrated a well-differentiated mucinous adenocarcinoma of appendiceal origin with metastasis in ovaries and peritoneum (pseudomyxoma peritonei).

Based on the results of our previous pilot study, we conducted a multi-institutional phase II study of combination chemotherapy consisting of oral UFT (Taiho Pharmaceutical Co. Ltd, Tokyo) plus cisplatin (CDDP) in patients with advanced non-small cell lung cancer (NSCLC). UFT capsule containing 100 mg tegafur and 224 mg uracil was orally administered in two divided doses on days 1 through 21 making the total tegafur dose 400 mg/m(2)/day (maximum 600 mg/body). CDDP was administered by drip infusion at a dose of 20 mg/m(2) on a 5-day schedule from day 8 to 12. Treatment was repeated every 4 weeks as long as the criteria for initiation of therapy were still met. Between April 1995 and March 1997, 51 patients were entered into the study. The mean age of all 50 eligible patients was 64 years(range: 40-78). There were 21 patients with clinical stage IIIB disease and 29 patients with IV disease. Thirty-two patients had adenocarcinoma, 14 had epidermoid carcinoma, and four had large cell carcinoma. Of the 47 assessable patients, 18 achieved a partial response with an overall response rate of 38.3% (95% confidence interval: 24.4-52.2%). The median response duration was 113 days. The median survival time of the eligible patients was 12.8 months, and the 1-year survival rate was 54%. Among the 51 patients enrolled, grade 3 or 4 leukopenia developed in one patient (2%), neutropenia in six patients (11. 8%), thrombocytopenia in six patients (11. 8%), and anemia in three patients (5. 9%). Non-hematological grade 3 or 4 toxicities included anorexia in 10 patients (19.6%), nausea in ten (19.6%), vomiting in two (3.9%), and diarrhea in two (3. 9%). Grade 3 abnormal laboratory data included bilirubinemia in four (7. 8%), GPT elevation in one (2.0%), and hematuria in one (2.0%). In conclusion, combination of CDDP plus oral UFT is efficacious, with low toxicity, in the treatment of advanced NSCLC. In particular, the low hematological toxicity may warrant application of this regimen to the treatment of elderly patients and in trials of concurrent chemoradiotherapy in patients with locally advanced NSCLC.

Metastasis into the hepatic hemangioma is a rare occurrence. We report a unique case of metastasis of intestinal carcinoma into hepatic hemangioma in a case of 65 year old male who presented with anorexia, weakness and headache. The postmortem examination revealed adenocarcinoma in the ileocaecal region. The liver showed a subcapsular hemangioma of 1.5 cms. diameter which on microscopic examination revealed metastasis of adenocarcinoma. The is the first documentation of metastasis in hepatic hemangioma. Such cases may pose problems of diagnostic difficulties and thus may result in mismanagement.

Lovastatin, an inhibitor of mevalonate synthesis, demonstrated in vitro antitumor activity against a variety of human cancer cells, especially in gastric adenocarcinoma cells at pharmacologically achievable concentrations. To determine the antitumor activity of this drug in advanced measurable gastric adenocarcinoma as well as to assess the toxicities and the pharmacokinetic features, we carried out a phase II study of high-dose lovastatin. Patients received lovastatin 35 mg/kg/day for 7 consecutive days, with ubiquinone (60 mg qid p.o.) to prevent rhabdomyolysis. The treatment was repeated every 28 days. From March 1996 to January 1997, 16 patients (median age, 57 years; range, 34-68) were entered into the study, 14 of whom were evaluated for response and toxicity. No patient achieved a response. A total of 28 cycles were administered. The median number of cycles was 2 (range, 1 to 4). Anorexia was the most common toxicity (64%), but decreased oral intake was observed only in 3 cycles. Two patients developed myalgia with elevated muscle enzyme. When used in this dosage and schedule, lovastatin does not appear to be effective for patients with advanced gastric adenocarcinoma.

Esophageal cancer is among the 10 most frequent cancers in the world. Iran is one of the known areas with a high incidence of esophageal cancer. Most of the patients in Iran have been reported from the north and northeast regions of the country. In one survey by the Iran Cancer Institute, 9% of all cancers and 27% of gastrointestinal cancers were esophageal carcinoma. The male to female ratio was 1.7/1. The distal portion of the esophagus is involved more often than other parts. Consumption of wheat flour, exposure to residues from opium pipes, drinking hot tea, and chewing nass (a mixture of tobacco, lime, ash, and other ingredients) are the suspect etiologic agents for esophageal cancer in Iran. Dysphagia, weight loss, anorexia, abdominal pain, and odynophagia are the common symptoms and signs of Iranian patients with esophageal cancer. For clinical staging, chest computed tomographic scanning is performed. Adenocarcinoma of the esophagus is not as common in Iran as in western countries. Public education, nutritional support, and eradication of opium addiction may decrease the morbidity and mortality that result from esophageal cancer. Surgery has traditionally been the mainstay of esophageal cancer treatment in Iran. Radiotherapy is mainly used postoperatively. The usual combination chemotherapy regimen is cisplatin plus flurouracil (5-Fu). Semin Oncol 28:153-157.

Although prostate cancer is one of the most commonly encountered malignancies in clinical practice, it is very unusual for prostate cancer to metastasize to the small bowel. Our search of the literature found no such cases published from 1966 to the present. We report the case of a 69-year-old man who presented for evaluation of anasarca and anorexia. He had a history of prostate cancer diagnosed 9 years before and had undergone a radical prostatectomy with subsequent radiotherapy for positive tumor margins. He developed anasarca 2 years before presentation to us. His serum albumin ranged between 1.5 and 2.5 g/dL. Upper endoscopy was performed for possible protein-losing enteropathy and the appearance of gastric and duodenal mucosa was found to be normal. Random small bowel biopsies revealed submucosal infiltrating adenocarcinoma with positive prostate-specific antigen stains consistent with the diagnosis of prostate cancer metastatic to the small bowel. This is a rare presentation of metastatic prostate cancer. Even though prostate cancer is the most commonly diagnosed cancer in American men, antemortem diagnosis of small bowel metastasis has not been reported. In patients with unexplained anasarca, especially with a history of malignancy, an upper endoscopy with small bowel biopsy may be useful in establishing the diagnosis.

Gastric neoplasia accounts for less than 1% of all canine malignancies. Malignant epithelial tumours are the most common gastric neoplasm in dogs and are referred to as carcinoma or adenocarcinoma. Dogs with gastric carcinoma usually present with vomiting, anorexia, and weight loss. The duration of clinical signs is from weeks to months. 1 Survey and contrast radiography, endoscopy, and ultrasonography have been used in the diagnosis of gastric carcinoma in dogs. This report describes a case of gastric carcinoma in which the survey and contrast radiographs and endoscopic findings were normal. Gastric neoplasia was suspected on ultrasound examination and confirmed histologically.
