Tumors of the central nervous system are an unusual cause of sudden death. This report describes the sudden death of a presumed healthy 28-year-old woman from primary diffuse leptomeningeal gliomatosis. She presented to an emergency room with headache and vomiting, subsequently became unresponsive and was pronounced dead 14 h later. Autopsy revealed a diffuse extensive infiltrate of well-differentiated astrocytoma in the leptomeninges of the brain and spinal cord without an underlying parenchymal tumor. Primary diffuse leptomeningeal gliomatosis is a rare tumor that arises within the leptomeninges from small neuroglial heterotopic rests that undergo neoplastic transformation. Grossly. this tumor can mimic leptomeningeal carcinomatosis, pachymeningitis, tuberculosis, sarcoidosis, and fungal infections. However, the histologic features of primary diffuse leptomeningeal gliomatosis should allow it to be readily distinguished from grossly similar conditions. The mechanism of death in this case is most likely tumor obstruction of cerebrospinal fluid outflow resulting in the usual complications seen with increased intracranial pressure. Although this tumor is aggressive and is associated with a rapidly progressive fatal course, it has not been previously associated with sudden death.

The paper highlights a series of questions that doctors need to consider when faced with end-stage cancer patients with bowel obstruction: Is the patient fit for surgery? Is there a place for stenting? Is it necessary to use a venting nasogastric tube (NGT) in inoperable patients? What drugs are indicated for symptom control, what is the proper route for their administration and which can be administered in association? When should a venting gastrostomy be considered? What is the role of total parenteral nutrition (TPN) and parenteral hydration (PH)? A working group was established to review issues relating to bowel obstruction in end-stage cancer and to make recommendations for management. A steering group was established by the (multidisciplinary) Board of Directors of the European Association for Palliative Care (EAPC) to select members of the expert panel, who were required to have specific clinical and research interests relating to the topic and to have published significant papers on advanced cancer patients in the last 5 years, or to have particular clinical expertise that is recognised internationally. The final constitution of this group was approved by the Board of the EAPC. This Working Group was made up of English, French and Italian physicians involved in the field of palliative care for advanced and terminal cancer patients; and of English, American and Italian surgeons who also specialized in artificial nutrition (Dr. Bozzetti) and a professor of health economics. We applied a systematic review methodology that showed the relative lack of RCTs in this area and the importance of retrospective and clinical reports from different authors in different countries. The brief was to review published data but also to provide clinical opinion where data were lacking. The recommendations reflect specialist clinical practice in the countries represented. Each member of the group was allocated a specific question and briefed to review the literature and produce a position paper on the indications, advantages and disadvantages of each symptomatic treatment. The position papers were circulated and then debated at a meeting held in Athens and attended by all panel members. The group reviewed all the available data, discussed the evidence and discussed what practical recommendations could be derived from it. An initial outline of the results of the review and recommendations was produced. Where there were gaps in the evidence, consensus was achieved by debate. Only unanimous conclusions have been incorporated. Subsequently the recommendations were drawn together by Carla Ripamonti (Chairperson) and Robert Twycross (Co-Chair) and refined with input from all panel members. The recommendations have been endorsed by the Board of Directors of the EAPC. It was concluded that surgery should not be undertaken routinely in patients with poor prognostic criteria, such as intra-abdominal carcinomatosis, poor performance status and massive ascites. A nasogastric tube should be used only as a temporary measure. Medical measures such as analgesics, anti-secretory drugs and anti-emetics should be used alone or in combination to relieve symptoms. A venting gastrostomy should be considered if drugs fail to reduce vomiting to an acceptable level. TPN should be considered only for patients who may die of starvation rather than from tumour spread. PH is sometimes indicated to correct nausea, whereas regular mouth care is the treatment of choice for dry mouth. A collaborative approach involving both surgeons and physicians can offer patients an individualized and appropriate symptom management plan.

Gastric adenocarcinoma is rarely observed in patients under the age of 40. Meningeal carcinomatosis as a first manifestation of disease is absolutely unique. If meningeal involvement occurs it is usually secondary event in previously diagnosed tumor. The prognosis is very unfavorable associated with short term survival. In the treatment of this disease there night be used either chemotherapy administered via lumbar injection or radiotherapy or combination of both. This case study is one of very few cases reported in literature when meningeal carcinomatosis was a first sign of advanced gastric adenocarcinoma. 39 years old woman was admitted to our hospital with severe headache, diplopia and vomiting. Meningeal carcinomatosis with gastric primary was diagnosed. She was treated with combination of cytosine arabinosid (Cytosar), methotrexate (Methotrexat), hydrocortisone (Hydrocortisone) administered via intrathecal lumbar injection and whole brain radiation. As a main complication she experienced disseminated intravascular coagulopathy. The improvement of patient's condition following the initial treatment had a very limited duration and the patient died of bilateral pneumonia and cerebral edema 44th day after the admission.

Peritoneal mesothelioma is a rare malignancy that is seen in patients exposed to asbestos or in young women with no known exposure to asbestos. The clinical features of the disease are similar in these two groups, and include peritoneal carcinomatosis, ascites, thrombocytemia, systemic symptoms (fever and night sweats), and hypercoagulability. There is no known curative therapy for this disease. Cisplatin has activity in 25% of patients. Mesothelial cells are known to contain high levels of carboxylesterase, a key enzyme in the activation of Irinotecan (CPT-11) to SN-38. This retrospective review of our experience in combining cisplatin 50 or 60 mg/m2 i.v. or i.p. on day 1 with CPT-11 50 or 60 mg/m2 i.v. on day 1, 8, and 15. Courses were repeated every 4 weeks x 6. If i.p. administration of cisplatin were feasible, it was the preferred route. Response to treatment was based on RECIST criteria. Fourteen men and 3 women, median age 62 years (35-76 years) and median PS 1 (0-2) were treated. Median number of courses was two for nonresponders and six for responders. The overall response rate was 24%, but 76% of patients improved on treatment. Median survival is not reached. Grade > or = 2 side effects included anemia (n = 6), neutropenia (n = 3), nausea/vomiting (n = 4), and constipation (n = 2). Grade 1 side effects were fatigue, anorexia, weight loss, alopecia, diarrhea, neuropathy, and gastric reflux. There were no grade > or = 3 hematologic toxicities. The combination of cisplatin and CPT-11 is well tolerated and has clinical benefits in patients with peritoneal mesothelioma.

Hepatobiliary neuroendocrine carcinoma was diagnosed in 17 cats in a period of 10 years. Seven tumors were of intrahepatic origin, one of which was a composite containing components of epithelial and neuroendocrine carcinoma. Nine tumors were of extrahepatic origin, and one tumor was located in the gall-bladder. The cats were adult and geriatric, and the male : female ratio varied according to tumor group. Hepatomegaly, anorexia, weight loss, and vomiting were the most common clinical signs observed in the cats with hepatic neuroendocrine carcinoma. The cats with extrahepatic neuroendocrine carcinoma showed these signs plus icterus (5/9) and high concentrations of hepatic enzymes. Histologically, the hepatic neuroendocrine carcinomas had two patterns, one with acinar structures separated by vascular stroma lined by cuboidal or columnar cells and the other solid with groups of anaplastic cells separated by vascular stroma. The composite tumor consisted of both bile duct carcinoma and neuroendocrine carcinoma. The extrahepatic neuroendocrine carcinomas and the gallbladder neuroendocrine carcinoma were characterized by solid sheets or groups of round to oval cells with vascular or fibrovascular stroma. Immunohistochemical examination of 10 of the neuroendocrine carcinomas revealed that all 10 stained with neuron-specific enolase; one bile duct carcinoma and the gallbladder carcinoma stained with chromogranin; four of five bile duct carcinomas and the gall bladder carcinoma stained with synaptophysin; and one bile duct carcinoma stained with gastrin. One cat with hepatic carcinoma had duodenal ulcer; in this cat, ultrastructural studies showed neurosecretory granules leading to the diagnosis of Zollinger-Ellison syndrome. In four cats in which necropsy was permitted, carcinomatosis (4/4), lymph nodes (4/4), lungs (2/4), and intestines (1/4) were the metastatic sites. Fourteen of the 17 cats were euthanatized during or immediately after surgery.

We report a patient with breast cancer who developed meningeal carcinomatosis that was preceded by a rapid increase in the serum level of carbohydrate antigen (CA) 19-9. A 60-year-old woman was admitted for primary breast cancer with multiple metastases to the vertebrae. She received cyclophosphamide 400 mg/m(2), epirubicin 40 mg/m(2), and 5-fluorouracil (5-FU) 400 mg/m(2) (CEF) chemotherapy every 3 weeks. Upon admission, her serum concentrations of carcinoembryonic antigen (CEA) and CA19-9 were 28.6 ng/ml and 99.2 U/ml, respectively. After three cycles of CEF therapy, her serum CEA decreased, and metastases to the vertebrae were attenuated. Her serum CA19-9 rapidly increased, however. A modified radical mastectomy was performed, but her serum CA19-9 levels still remained high (>500 U/ml). After four cycles of CEF therapy, she experienced headaches and vomiting due to an increase in cerebrospinal pressure, and she was diagnosed with meningeal carcinomatosis. At the time of this diagnosis, the concentration of CA19-9 in her cerebrospinal fluid was greater than 500 U/ml, and immunohistochemical examination revealed that carcinoma cells in the cerebrospinal fluid overexpressed CA19-9. To our knowledge, this is the first report of the development of meningeal carcinomatosis from CA19-9-producing breast cancer cells, showing thatCA19-9 expression was associated with breast tumor progression.

The first discovery of a cerebellar metastasis of pancreatic carcinoma in a living patient is described. Two years earlier the patient had undergone a pancreaticoduodenectomy for an adenocarcinoma of the head of the pancreas with a lymph node metastasis. After complete surgical removal of the tumor, he underwent adjuvant chemoradiation. Two years later the patient presented with intractable vomiting, which was attributed to peritoneal carcinomatosis. Clinical evaluation revealed an intracranial tumor without signs of pancreatic recurrence. The tumor was surgically removed. One year later the patient developed multiple brain metastases and he is currently undergoing gemcitabine-based chemotherapy.

A prospective protocol for treatment of malignant inoperable bowel obstruction was implemented at Grenoble University Hospital Center for 4 years. All 80 episodes of obstruction resulted from peritoneal carcinomatosis and none could expect another treatment cure. The protocol comprised three successive stages. Stage I included treatment for 5 days with a corticosteroid, antiemetic, anticholinergic, and analgesic. Stage II provided a somatostatin analogue if vomiting persisted. After 3 days, Stage III provided a venting gastrostomy. Obstruction relief with symptom control was obtained by medical treatment in 29 cases and symptom control occurred alone in an additional 32 cases. Ten patients were relieved by venting gastrostomy. Symptom control without permanent nasogastric tube (NGT) placement occurred in 72 episodes (90%). Eight patients with refractory vomiting were obliged to continue the NGT until death. Fifty-eight obstruction episodes (73%) were controlled in 10 days or less. Median time before gastrostomy was 17 days. Median survival was 31 days. This series suggests that a staged protocol for the treatment of inoperable malignant bowel obstruction is highly effective in relieving symptoms. A subgroup experiences relief of obstruction using this approach.

Malignant bowel obstruction (MBO) is a common and distressing outcome particularly in patients with bowel or gynaecological cancer. Radiological imaging, particularly with CT, is critical in determining the cause of obstruction and possible therapeutic interventions. Although surgery should be the primary treatment for selected patients with MBO, it should not be undertaken routinely in patients known to have poor prognostic criteria for surgical intervention such as intra-abdominal carcinomatosis, poor performance status and massive ascites. A number of treatment options are now available for patients unfit for surgery. Nasogastric drainage should generally only be a temporary measure. Self-expanding metallic stents are an option in malignant obstruction of the gastric outlet, proximal small bowel and colon. Medical measures such as analgesics according to the W.H.O. guidelines provide adequate pain relief. Vomiting may be controlled using anti-secretory drugs or/and anti-emetics. Somatostatin analogues (e.g. octreotide) reduce gastrointestinal secretions very rapidly and have a particularly important role in patients with high obstruction if hyoscine butylbromide fails. A collaborative approach by surgeons and the oncologist and/or palliative care physician as well as an honest discourse between physicians and patients can offer an individualised and appropriate symptom management plan.

Cancer in the central nervous system can arise from a primary brain tumor and metastasize to the brain or to the leptomeninges, leading to leptomeningeal metastasis (LM). LM also is called leptomeningeal carcinomatosis and carcinomatous meningitis. When LM occurs, signs and symptoms include headache, nausea, vomiting, lumbar back pain, and stiff or painful neck; LM also may lead to mental disturbances and seizures. Nursing care of patients with LM requires an understanding of neurologic anatomy and physiology, along with associated treatments and complications. Treatment of LM may involve intrathecal or, more likely, intraventricular chemotherapy. Very little has been written about appropriate care of patients with LM. The purpose of this article is to review the literature, summarize clinical care recommendations, and construct evidence-based guidelines for the administration of intraventricular chemotherapy and the care and monitoring of patients with LM.
