A 66-year-old female presented with a large abdominal mass and accompanying systemic complaints of abdominal pain, constipation. and fever. On exploratory laparotomy, the mass was found to be a moderately differentiated adenocarcinoma of the sigmoid colon with metastasis to the left ovary. A primary colorectal carcinoma that has metastasized to the ovaries can be difficult to distinguish clinically from an advanced primary ovarian tumor. Histology and tumor markers are currently the most useful tools available in making an accurate diagnosis. If the nature of the primary tumor is uncertain and the initial response to chemotherapy is poor, the patient's prognosis will also he poor. Though controversy exists regarding the role of prophylactic bilateral oophorectomy during resection for primary colorectal cancer, later confusion can be avoided by performing this procedure when the colorectal carcinoma is first diagnosed. However the possibility of a concurrent primary ovarian tumor must not be overlooked.

Hypercalcemia is a well-known manifestation of paraneoplastic syndromes associated with a variety of malignancies. However, colon cancer has only rarely been associated with hypercalcemia of malignancy. We present the case of a patient with recurrent adenosquamous carcinoma of the ascending colon found to have hypercalcemia. The patient is a 76-year-old white woman who initially presented with colon cancer in the cecum and underwent a right hemicolectomy. All lymph nodes and surgical margins were free of tumor. Pathological examination at that time revealed adenosquamous carcinoma of the colon. Eight months later she complained of dizziness, anorexia, and constipation and was found to have a calcium level of 13.6 mg/dL. CT scan revealed a mass measuring 10.5 to 12.7 cm in the right hepatic lobe, and a bone scan was normal. Her intact parathyroid hormone (PTH) level was 6 pg/mL (normal 12-72) and her PTH-related protein (PTHrP) level was 25.7 pmol/L (normal <1.3). She then underwent a hepatic resection. The serum PTH, calcium, and PTHrP levels normalized after resection. Hypercalcemia of malignancy in colon cancer is rare and has an association with adenosquamous histology. The hypercalcemia is attributed to PTHrP, and here we demonstrate this in the serum and tumor specimens. The effects of PTHrP are shown to be short-lived postoperatively. We find only 14 other cases in the literature of hypercalcemia related to a colonic neoplasm, and this is the only patient reported to be surviving. The diagnosis of a paraneoplastic syndrome mediated via PTHrP should be considered when hypercalcemia is encountered in the setting of metastatic colon carcinoma.

Neurogenic bowel in spinal cord injury (SCI) can present with constipation and diarrhea as ongoing problems. Usually, these manifestations are adequately controlled with modification in the bowel program. When these symptoms persist, other causes should be considered. This case report describes a jejunal carcinoid tumor with colonic extension that was diagnosed in a paraplegic patient with persistent constipation and diarrhea. A 39-year-old man sustained a T1 paraplegia with neurogenic bowel and bladder dysfunction from a gunshot wound. His bowels were initially managed adequately with digital disimpaction. Over the next 8 years, he had intermittent constipation that was managed with the addition of various suppositories. He then developed progressively worsening constipation, and other gastrointestinal (GI) symptoms. Although his symptoms initially resolved with medical management, the constipation worsened. Upper endoscopy revealed a submucosal bulge in the duodenal bulb. A month later, gallstones were found on renal ultrasound performed to evaluate recurrent urinary tract infections. He underwent cholecystectomy, but his GI symptoms persisted over the next several months. Repeat upper endoscopy subsequently revealed an ulcerated tumor at the duodenojejunal flexure. An upper-GI scan with small bowel follow through showed a proximal jejunal mass. The patient underwent laparotomy with resection of the mass. Final pathologic diagnosis was malignant carcinoid tumor. This case shows the importance of entertaining other clinical entities in patients with SCI when constipation and diarrhea persist despite adequate management.

A 72-year-old man was referred for geriatric evaluation with a view toward placement in institutional care. He presented originally to an internal medicine team with a six-month history of weight loss, constipation, generalized weakness, and apathy; investigations to rule out an underlying neoplasm were negative. Interdisciplinary assessment revealed coexisting dementia, myopathy, and oropharyngeal dysphagia. These findings prompted further diagnostic evaluation and a diagnosis of inflammatory myopathy with associated oropharyngeal dysphagia and dementia was made. The dementia, myopathy, and oropharyngeal dysphagia responded to steroids and rehabilitation and the patient regained his independence.

Tumor angiogenesis is a critical factor in the growth and metastasis of most malignant neoplasms. Thalidomide (Thalomid), banned from clinical use in the 1960s because of severe teratogenicity, has been shown to possess antiangiogenic properties. A recent clinical trial of antiangiogenic therapy with thalidomide demonstrated significant activity in a group of patients with relapsed refractory myeloma. Although its mechanism of action remains unclear, several trials have since confirmed that thalidomide is active in 25% to 35% of patients with relapsed myeloma. As a result, thalidomide has reemerged in clinical practice and is now actively being studied in the treatment of several cancers. Major toxicities associated with the use of thalidomide include constipation, sedation, skin rash, fatigue, and peripheral neuropathy. This article summarizes the current status of thalidomide therapy in cancer.

Platinum-based chemotherapy is considered standard treatment for advanced non-small-cell lung cancer (NSCLC). However, toxicity of most platinum-based regimens is substantial and requires close monitoring and supportive care. Over the past decade, paclitaxel, docetaxel, vinorelbine, gemcitabine, irinotecan, and topotecan have been introduced into the clinic. These newer agents have shown promising activity against NSCLC with a favorable toxicity profile as single agents. For patients with metastatic NSCLC, palliation is the main goal of therapy. Therefore, treatment should be easy to administer on an outpatient basis. We explored a novel combination therapy avoiding platinum. Patients with recurrent or metastatic NSCLC were treated with intravenous (i.v.) topotecan (0.5-1.0 mg/m(2)/day x 5) and i.v. vinorelbine (20-30 mg/m(2)/day on day 1 and day 5) in 21-day cycles. Dose-limiting toxicity (DLT) was defined separately with or without the addition of granulocyte colony-stimulating factor (G-CSF) support. Twenty-nine patients have been enrolled to date. At i.v. topotecan doses of 0.75-1.0 mg/m(2)/day and i.v. vinorelbine of 25 mg/m(2)/day, neutropenia was frequent but of short duration (<7 days). The DLT of i.v. topotecan (0.85 mg/m(2)) in the absence of G-CSF support was based on myelosuppression with neutropenic fever. With the addition of G-CSF, a DLT has not been reached. Nonhematologic toxicities included mild to moderate fatigue and constipation. An overall clinical response rate of 42% was achieved, with responses noted at all dose levels. At a short median follow-up of 15 months, the median survival for all patients is 13 months. In conclusion, the combination regimen of topotecan and vinorelbine is feasible for outpatient administration and is well tolerated with less toxicity than platinum-based regimens. Preliminary response data demonstrate good tumor activity, suggesting that this regimen could make an excellent palliative treatment for advanced NSCLC.

A 13-year-old castrated male Bassett Hound was examined because of a 2-week history of severe constipation and tenesmus. Radiography revealed a large cystic mass in the caudal portion of the abdomen that was compressing the urethra and obstructing the pelvic canal. A small perianal mass was also noticed in the region of the left anal sac. Exploratory surgery was performed, but the mass was deemed unresectable. Instead, the mass was incised, drained, and omentalized in an attempt to establish continuous drainage after surgery. Cytologic evaluation of the perianal mass was consistent with a diagnosis of anal sac adenocarcinoma. Histologic evaluation of the abdominal mass revealed it was a lymph node effaced by adenocarcinoma. Despite the poor prognosis for anal sac adenocarcinoma with metastatic spread to the sublumbar lymph nodes, tenesmus and dysuria in this dog remained palliated until the dog's death 18 months after surgery. Omentalization was successful in providing a continuous method of fluid drainage for this cystopapillary abdominal tumor.

Palliative medicine has as its goal improving the quality of life of patients with incurable diseases and their family members. According to the WHO, alleviating pain and other physical symptoms, as well as addressing psycho-social and spiritual problems have the highest priority. The role of medicine and the physician is inseparably linked to psycho-social and nursing resources in a multi-disciplinary team. Advanced stages of cancer are particularly characterized by symptoms which can cause lasting impairment of normal life. In addition to pain, patients suffer from other, often extremely distressing physical symptoms such as constipation, nausea and vomiting, gastrointestinal obstruction and difficulty in breathing. The first priority is to determine the causes of the individual symptoms, since therapeutic decisions are based on the specific pathophysiological mechanisms. Effective symptom management presupposes exact knowledge of the pharmacokinetics. The often difficult decision between causal and symptomatic therapy options must - whenever possible - be made together with the patient and frequently in interdisciplinary medical consultation. Tumor pain therapy follows the guidelines of the World Health Organization. Crucial are long-term therapy and dose titration of the analgesics, stepped progression between the groups of medication, and specific therapy approaches for neuropathic pain components. The significance of constipation with its variety of possible complications is often underestimated in the context of the tumor patient. Effective prophylaxis and cause-based therapy do improve the nutritional care and can help to prevent the transition to an ileus. New findings concerning the role of neurotransmitters in triggering nausea and vomiting have opened up specific methods of attack. Dyspnoea therapy places high demands on the medical team, since nursing measures must effectively supplement the more limited medical possibilities.

A 58-year-old man was treated for a granular cell tumor (GCT) of the pancreas; a very rarely occurring tumor. The patient, who had been followed for 6 years due to alcoholic hepatitis, chronic pancreatitis and elevated carcinoembryonic antigen (CEA) levels from smoking, was admitted to our hospital for evaluation of back pain, diarrhea and constipation. The patient was diagnosed as having pancreatic head cancer using clinical imaging studies, and a pylorus-preserving pancreatico-duodenectomy was done. In the resected specimen, a white tumor measuring 13 mm in diameter was observed at the pancreatic head, and there was marked fibrous change surrounding the tumor. The microscopic appearance of the pancreas showed atrophy of acinar cells, fibrosis, and dilatation of the main pancreatic duct (MPD). Within the tumor were oval cells with low-grade atypia and an increased number of diffuse eosinophilic granules. Neither mitosis nor invasive findings were observed. Periodic acid-Schiff staining and immunohistochemical staining for the S-100 protein were positive, thus the tumor was diagnosed as a benign GCT. In addition, carcinoma in situ was found at the dilated MPD. Therefore, this patient was diagnosed as having GCT with carcinoma in situ of the pancreas. To the best of our knowledge, this is only the fourth case of GCT of the pancreas to be reported.

Total colectomy with ileorectal anastomosis (TC) is a well-accepted procedure for many colonic pathologies but data on faecal incontinence and related quality of life after TC are lacking. The aims of this study were to assess the long-term bowel frequency, degree of incontinence and quality of life with respect to faecal incontinence and to compare them with the outcome for TC for different diagnostic groups. We identified 54 patients who had undergone TC at Singapore General Hospital and interviewed them using two questionnaires: the faecal incontinence quality of life (FIQL) scale and the Wexner faecal incontinence score (WS). The patients were allocated in 3 groups based on the primary diagnosis leading to operation, i. e. slow-transit constipation or megacolon (STC), colonic neoplasm (CA) and complicated pan-colonic diverticular disease (DD). Median bowel frequencies for STC and DD groups were 2.5/day; for CA, it was 3.5/day (p=0.042). There was no significant difference in the FIQL score and WS between the groups. Eleven patients had some degree of faecal incontinence based on WS. Many patients (20.4%) with perfect continence had fear of faecal leakage affecting their quality of life. In conclusion, patients with frequent stools do not need to have incontinence to suffer from the fear of it. The primary pathology leading to TC made no difference to the faecal incontinence or bowel urgency problems.
