The cholangiocarcinoma is a low-prevalence neoplasia, but represents a great medical challenge in its diagnosis and treatment because of its insidious clinical manifestations. Its cellular origin has been associated to other hepatic tumors, and to multiple congenital or acquired factors (infections, drugs and other diseases). The most frequent histological type is the
adenocarcinoma
and the most common localization is the choledochal duct; local metastases are frequently found in autopsies. The usual clinical findings are pruritus, weight loss,
anorexia
, jaundice and hepatomegaly. The immunohistochemical advances related to oncogenes (ras & C-erb B-1) and tumor markers (Epidermal Growth Factor and Integrin among others) allow to make differential diagnosis with other hepatic cancers and will provide valuable information about its cell biology. The initial approach to patients with this disease is made by ultrasound (US), which can be associate to Doppler; Computed Axial Tomography and Nuclear Magnetic Resonance have similar sensitivity and specificity, so they are preferred to US in the elderly with history of weight loss. It's better to perform Percutaneous Transhepatic Cholangiography than Endoscopic Retrogrado Pancreatocholangiography when its possible because the first permits a comprehensive visualization of the biliary tree. The treatment includes resection and endoprosthesis placement. The combination of surgery, Chemotherapy and Radiotherapy allows to achieve the best survival rates, and opens a door to new strategies related to this malignancy.

Tumor metastasis to the hypophyseal system has rarely been reported with either clinical or radiographic evidence. A 52-year-old woman presented with polydipsia, polyuria, and
loss of appetite
. She was diagnosed as having diabetes insipidus caused by pituitary micrometatasis of lung
adenocarcinoma
. After she had been treated with radiation therapy to the pituitary gland, the gland size was reduced as confirmed by magnetic resonance imaging, and her urine volume decreased. However, meningitis carcinomatosa appeared later. This was a rare case of secondary diabetes insipidus due to pituitary metastasis of lung cancer.

21 patients with squamous oesophageal carcinoma were treated with a new regimen designed in our unit and effective in treating gastric
adenocarcinoma
, consisting of continuous venous infusion of 5-fluorouracil for up to 24 weeks (200 mg/m2/day) with epirubicin (50 mg/m2) and cisplatin (60 mg/m2) every 3 weeks. 12 patients (57%) had an objective response. The median relapse free period was 7 months, median survival from start of chemotherapy 8.4 months, and median survival from diagnosis, 14 months. Symptomatic improvements were reported by 10/11 patients with pain (91%), 8/9 with
anorexia
(89%), 8/10 with reflux (80%) and 10/14 with dysphagia (71%). Grade 3 or 4 toxicity was reported by 11 patients: 5 had haematological toxicity, 3 vomiting, 2 infection and 1 diarrhoea. One patient developed peripheral neuropathy, 1 renal impairment and another peripheral vascular disease. Following chemotherapy, surgery was attempted in 5 patients. One remains well 3 years on, 2 had macroscopic clearance of tumour but died of postoperative complications. In 2, disease was irresectable. This regimen of moderate toxicity is effective at improving symptoms in the majority of patients. In some patients, tumours are briefly downstaged so that inoperable tumours may become operable.

A 75-year-old female had
loss of appetite
, left hypochondrial and back pain. An X-ray and a computed tomogram of both lungs showed multiple small granular shadows. By Tc-labelled bone scintigram, multiple uptakes were found. Since high serum CA19-9 was obtained, pancreatic or bile duct cancer with multiple lung and bone metastasis was suspected. The autopsy revealed, small nodules in both lungs were well-differentiated
adenocarcinoma
, bronchiolo-alveolar type, and immunohistologically, tumor cells were stained positively for CA19-9. Since CA19-9 exists in normal bronchial glands and bronchiole, high level of serum CA19-9 in our patient may be derived from the neoplastic bronchiolar epithelium.

Small bowel adenocarcinomas account for 3% of gastrointestinal malignancies, and 20 to 25% of these arise in the ileum. Clinical presentation is variable, and early diagnosis is difficult. A 56-year-old postmenopausal woman presented with crampy abdominal pain,
anorexia
, and weight loss. Pelvic examination and ultrasound revealed a 6 x 8-cm complex right adnexal mass. At laparotomy, en bloc resection of the right adnexa and the densely adherent ileal segment was performed along with a hysterectomy and a left salpingo-oophorectomy. The final pathology showed a moderately differentiated invasive
adenocarcinoma
of the ileum with a malignant enterotubal fistula. This is the first case reported in the literature of an ileal
adenocarcinoma
with a tubal fistula masquerading as an adnexal mass.

An extremely rare case of esophageal metastasis from prostate cancer is reported. A 65-year-old man presented with
anorexia
and back pain. Upper gastrointestinal X-ray fluoroscopy and endoscopy revealed a shallow longitudinal ulcer, with converging mucosal folds, approximately 5 cm above the esophagogastric junction. The histological diagnosis of the biopsied specimen was
adenocarcinoma
. Blood biochemistry revealed elevated serum prostate-specific antigen (PSA) and gamma-seminoprotein levels. Ultrasonography of the prostate disclosed a hypoechoic lesion in the left lobe, and needle biopsy led to the diagnosis of prostatic adenocarcinoma. Since there was no finding suggestive of a primary lesion, apart from that in the prostate, we conducted reverse transcriptase-polymerase chain reaction (RT-PCR) for PSA. PSA-positive mRNA was demonstrated in the tissue of the esophageal tumor. There are three reports on metastasis to the esophagus from prostate cancer, but this is the first case of esophageal metastasis from prostate cancer without any evidence of metastasis to other organs. The importance of RT-PCR for the diagnosis of primary lesions of metastatic cancer is discussed.

We reported a case of long survival brain metastasis and meningeal carcinomatosis from lung cancer without radiochemotherapy. A 59-year-old female admitted to our hospital suffered from headache,
anorexia
and nausea. Papilledema was noticed, and examinations showed a brain tumor in the left parietal lobe and cancer cells in cerebrospinal fluid. Removal of the tumor and ventriculoperitoneal shunt were performed. Pathology showed
adenocarcinoma
. No neurological deficit was found during the postoperative course and the patient asked for home treatment. She survived for 25 months and spent a useful life in the 15 months after the onset in spite of no radiochemotherapy for meningeal carcinomatosis. In this case, because of the slow progression of the clinical symptoms, it is considered that cancer cells in the cerebrospinal fluid space grow slowly. The first CT and MRI findings of metastatic tumor of this case showed atypical for brain metastasis. Calcifications were found in plain CT and a high intensive tumor in both T1 and T2 weighted images of MRI. Enhancement due to contrast media was very slight in both CT and MRI. We considered that these findings were related to the slow growing of cancer cells.

Combined use of 5-fluorouracil (5-FU) and cisplatin has proven to have synergistic effects in many experimental systems and clinical studies. UFT, an oral preparation of uracil and tegafur in a 4:1 molar ratio, was reported to have enhanced activity as compared with 5-FU or tegafur alone against various human tumors. Based on those results, we conducted a pilot study to confirm the feasibility and antitumor effect of UFT in combination with cisplatin in patients with advanced non-small cell lung cancer (NSCLC). UFT was orally administered at a dose of 400 mg/m2 according to a protocol for step-wise prolongation of the administration period, such as days 1-14 in step I, days 1-21 in step II, days 1-28 in step III. During to course, cisplatin was administered at a fixed dose of 20 mg/m2/day on days 8 through 12. The course was repeated every 4 weeks. Numbers of patients enrolled in steps I, II, III were six, ten and six (a total of 22), respectively. There were three females and 19 males, PS scored 0/1/2 = 7/14/1, stage IIIA/IIIB/IV = 3/8/11.
Adenocarcinoma
/squamous cell carcinoma/large cell carcinoma = 11/7/4, and median age 68 (range 52-79). All 22 patients were evaluable for toxicity, and 21 for efficacy. Compliance of UFT declined as the administration period of UFT was prolonged. In step I, one patient had grade 3 toxicity of each neutropenia, thrombocytopenia, nausea/vomiting and diarrhea. In step II, grade 3, 4 neutropenia was seen in four patients, grade 3 thrombocytopenia and
anorexia
in one patient, and grade 3 nausea/vomiting in four patients. In step III, there was grade 3 neutropenia in two patients and grade 3
anorexia
in one patient. All other toxicities were mild. The overall response rate was 38% (one CR and 7 PR, 95% C.I.: 21-59%). Combination therapy with oral UFT and 5-day infusion of cisplatin is feasible with substantial antitumor effect against advanced NSCLC. Since UFT compliance decreased in step III (no patient in step III received > 2 courses of treatment), we considered the step II schedule to be worth for further evaluation in a combination phase II study.

Sequential chemotherapy with methotrexate and 5-fluorouracil (MTX/5-FU) for advanced gastric cancer was given 29 patients. The procedure consisted of weekly MTX 100 mg/m2 (i.v.) followed three hours later by 5-FU 600 mg/m2 (i.v.) with leucovorin rescue on each of the following two days. Nine of 28 patients (32.1%) showed partial response to this treatment. Response rates were 28.6% in the 21 cases with poorly differentiated
adenocarcinoma
and 42.9% in the 7 cases with well- or moderately-differentiated
adenocarcinoma
. This procedure was especially effective for primary lesions (PR 9/20: 45%) and lymphnode metastases (CR 4 + PR 4, 8/17: 47.1%). Side effects were mild leukopenia and G-I symptoms such as nausea, diarrhea and
loss of appetite
, except in 1 patient who died of severe myelosuppression with sepsis. We concluded that sequential MTX/5-FU therapy is fairly effective and the adjuvant chemotherapy of choice for advanced or recurrent gastric cancer with not only poorly differentiated
adenocarcinoma
but also well- or moderately-differentiated
adenocarcinoma
.

Cancer is consistently associated with
anorexia
. The Lobund-Wistar rat model of prostate cancer exhibits clinical manifestations (including
anorexia
) that resemble many aspects of the human disease. Cytokines are proposed to be involved in cancer-associated
anorexia
. Here we investigated mRNA profiles of feeding-modulatory cytokines and neuropeptides in specific brain regions of anorectic Lobund-Wistar rats bearing prostate
adenocarcinoma
tumor cells. Interleukin (IL)-1beta system components (ligand, signaling receptor, receptor accessory proteins, receptor antagonist), tumor necrosis factor-alpha, transforming growth factor-beta1, glycoprotein 130 (IL-6 receptor signal transducer), proopiomelanocortin (POMC, opioid peptide precursor), and neuropeptide Y (NPY) mRNAs were analyzed with sensitive and specific RNase protection assays. The same brain region sample was assayed for all components. The data show that early
anorexia
in tumor-bearing rats was associated with an upregulation of IL-1beta mRNA in the brain regions examined (cerebellum, cortex, and hypothalamus). IL-1 receptor antagonist (IL-1Ra) mRNA and IL-1 receptor type I mRNA levels were also significantly increased in the cortex and hypothalamus. All other cytokine components, POMC, or NPY mRNA levels were not significantly different between tumor-bearing and pair-fed (control) rats. IL-1beta mRNA and IL-1Ra mRNA were also significantly upregulated in the spleen of tumor-bearing rats. These data suggest that 1) IL-1beta mRNA upregulation in the brain may be relevant to the
anorexia
exhibited by the tumor-bearing Lobund-Wistar rat and 2) in vivo characterization of cytokine components in discrete brain regions during cancer is necessary to understand underlying molecular mechanisms responsible for cancer-associated neurological manifestations.
