Small bowel carcinoid tumors usually metastasize to regional lymph nodes and the liver but metastases to the neck are extremely rare. Over a ten-year period 48 cases of small bowel carcinoid were diagnosed at our institution and of these, three cases (6%) were associated with neck metastases--one to the thyroid gland and two to cervical lymph nodes. The former patient and one of the latter patients had symptoms of the carcinoid syndrome. The other patient was asymptomatic and presented with a solitary neck mass. Urine levels of 5-hydroxyindolacetic acid (5-HIAA) were elevated in the two symptomatic patients but were undetectable in the asymptomatic patient. Extirpation of the involved cervical nodes and the primary small bowel lesion was performed in two patients. In addition, both patients have received chemotherapy with 5-fluorouracil. One patient remains asymptomatic four years after diagnosis but the other patient continues to have five to six bowel movements per day nine months after operation. Small bowel resection was performed in the patient with a metastasis to the thyroid. This patient died of sepsis after a second operation for an intraabdominal abscess. The histological patterns of the primary tumor and the metastatic lesions were similar and the cells of the metastases contained argentaffin-positive granules. We conclude that 1) an intraabdominal carcinoid tumor should be considered as the location of the primary tumor in patients who present with a neck mass containing metastatic carcinoid and 2) the prognosis for patients with extraabdominal metastases is similar to that for patients with intraabdominal disease only.

Neutropenic enterocolitis (NE) is an unusual complication of neutropenia. Its presentation is dramatic, treatment is controversial, and the outcome may be devastating. The available literature about this entity is mainly case reports and autopsy studies. We have recently performed a celiotomy on a patient who developed sepsis and an acute surgical abdomen three days following chemotherapy and radiotherapy for a metastatic adenocarcinoma with no known primary tumor. At surgery he was found to have a boggy right and recto-sigmoid colon with a grossly normal transverse colon. Intraoperative colonoscopy revealed mucosal ulceration and necrosis extending from the dentate line to the cecum. A total abdominal colectomy, closure of the rectal stump, and an ileostomy was performed. Postoperatively, the patient recovered from the abdominal septic process only to succumb to multiple system organ failure secondary to pulmonary sepsis. Upon review of the literature, we found 65 cases of NE that were suspected or diagnosed in the antemortem state and confirmed at surgery or autopsy. In this review, we intend to analyze these case reports, summarize the salient features of the disease and outline the optimal therapeutic approach.

From October 1995 to June 1997, 19 chemotherapy-naive patients with pathology-proven locally advanced or metastatic biliary tract carcinomas (BTC) were enrolled. The regimen consisted of 5-fluorouracil (5-FU) 2600 mg/m2 and leucovorin (LV) 150 mg by weekly 24 h infusion for 6 weeks and followed by a 2 week break. The treatment was terminated if disease progressed, the patient refused or unacceptable toxicity occurred. All patients required a Port-A catheter insertion and were treated at outpatient clinics by portable infusion pumps. There were 12 males and seven females with a median age of 62 years (range 45-77). The primary tumor sites were nine intrahepatic cholangiocarcinomas (CC), three perihilar CC, one distal BTC and six gallbladder cancers. A total of 179 chemotherapy sessions were given with a mean of 9.5 (range 2-18). Eighteen patients were evaluable for response. The response rates were: 33% (six of 18) partial response (PR), 39% (seven of 18) stable disease (SD) and 28% (five of 18) progressive disease (PD). All of the patients were evaluable for toxicity. The most common toxicities were mild fatigue (nine of 19, 47%), loss of appetite (nine of 19, 47%), skin hyperpigmentation (five of 19, 26%) and diarrhea (two of 19, 11%). Only one patient had grade IV myelotoxicity with sepsis but without treatment-related death. The median time to progression was 4 months. The overall median survival time was 7.0 months. The median survival time of the PR was not reached, SD was 8.0 months and PD 3.5 months. In conclusion, weekly high-dose 5-FU with LV by 24 h infusion in an outpatient setting for patients with BTC is effective, only mildly toxic and deserves further study.

Enterocutaneous fistulae that develop in patients with cancer represent a difficult management situation, which is often complicated by prior treatment including surgery, radiation therapy, and chemotherapy. A fistula may in turn delay potentially beneficial treatment of the underlying malignancy. To provide a better understanding of this problem, we reviewed the National Institutes of Health experience with enterocutaneous fistulae in adult patients with cancer. The medical records of patients with cancer who developed a fistula from the gastrointestinal tract during the period 1980 through 1994 were reviewed. Etiology, management, outcome, and impact on further treatment were assessed. Twenty-five patients with gastrointestinal fistulae were identified. The most common primary tumor site was the colon/rectum in males and the ovary in women. The majority of patients had metastatic disease at diagnosis and a history of prior therapy and presented with anorexia and weight loss. The fistula was usually single, most commonly developed from the jejunum/ileum (13 patients) or colon/rectum (6 patients), and occurred postoperatively after procedures on the small bowel (10 patients) or colon (8 patients). Malnutrition and sepsis developed in 60 per cent of patients. Thirty-day mortality was 16 per cent and correlated with prior radiation therapy, location and output from the fistula, and hypoalbuminemia. An enterocutaneous fistula negatively impacted on the provision of further therapy for the majority of patients (63%). Enterocutaneous fistula in the patient with cancer occurs most frequently in the setting of extensive prior therapy and is associated with prolonged morbidity. Identification of high-risk patients and early management of fistulas once they develop may prevent delays in subsequent cancer therapy and decrease morbidity.

Urologic emergencies are common in the cancer patient and relate mainly to complications of bladder hemorrhage, upper or lower urinary tract obstruction, urinary tract infection, and priapism. Hemorrhagic cystitis is commonly due to bladder injury from radiation therapy, viral infection, or metabolites of chemotherapeutic agents. Treatments aimed at ameliorating the effects of theses metabolites, such as mesna and intravenous (IV) hydration, coupled with cystoscopy, evacuation of clots, and formalin instillation, have given clinicians an effective means of avoiding exsanguinating hemorrhage from the bladder. Malignant ureteral obstruction is an ominous sign in the cancer patient and may be due to tumor compression, retroperitoneal adenopathy, or direct tumor invasion. The endourologic procedures of ureteral stenting and percutaneous nephrostomy are effective means of palliation; however, complications of infection, stent obstruction, and stent migration can result in hospital admission and a decline in quality of life. Median survival for patients with malignant ureteral obstruction is less than 7 months, regardless of the tumor of origin. Bladder outlet obstruction leading to urinary retention can be due to mechanical factors involving the bladder neck or prostate, or to a breakdown in the neurophysiologic function of the bladder. Every attempt is made to avoid surgical intervention or the placement of chronic in-dwelling catheter in these often debilitated patients. Patients are often effectively treated with a variety of pharmacologic agents, such as alpha-adrenergic receptor blockers or by the initiation of chronic intermittent catheterization. Urinary tract infections are particularly dangerous in neutropenic and bone marrow transplant patients, with bladder catheters the most common portal entry. The colonization and later infection by resistant nosocomial organisms, such as Pseudomonas aeruginosa and Candida albicans, can rapidly lead to life-threatening sepsis. On rare occasions, emergency surgical intervention with adequate open drainage or nephrectomy is required to control such infections. Priapism can be caused by hematologic malignancy with hypercoagulation, metastatic disease involving the corpora cavernosa with thrombosis of the venous outflow from the penis, or rarely from intracavernous injections used for the treatment of impotence. If effective treatment exists for the primary tumor, improvement or resolution of the state of priapism may occur. Radiation therapy may be required to decrease the pain associated with malignant priapism, but surgical shunting procedures are rarely effective.

The long-term survival rate of patients with carcinoma of the pancreas is low. Even more so, long-term survival of patients with metastatic pancreatic carcinoma is extremely rare. In this case report, we describe a patient with an unusual course of disease. This patient was diagnosed with locoregional carcinoma of the pancreas and therefore underwent gastroenterostomy and cholecystojeojenostomy without resection of the primary tumor. Later he was treated with radiotherapy and chemotherapy and survived 12 years, during 11 of which he had no evidence of disease. He died 12 years after the initial diagnosis from peritoneal dissemination of poorly differentiated carcinoma complicated with obstructive jaundice and sepsis. To our knowledge, this patient had the longest reported survival with locally advanced pancreas carcinoma that was not resected. The case is presented and discussed in this article.

Our purpose was to evaluate long-term outcome in patients presenting with acute colonic perforation in the setting of colorectal cancer. We conducted a retrospective review of 48 consecutive patients presenting with acute colonic perforation associated with colorectal cancer at a single institution. Patients presented either with free air or acute peritonitis. No patients with colonic obstruction were included. Forty-eight patients presented with colon perforation. Thirty-six had perforation at the tumor, 11 proximal to the tumor, and one distal to the primary tumor. Patients who perforated proximal to the tumor were older (74.5 +/- 2 vs 64.7 +/- 3; P < 0.04) and had a longer length of stay (46.8 +/- 17 vs 11.6 +/- 1 P < 0.001). Fourteen patients had stage II disease, 19 stage III, and 15 stage IV. Thirty-day mortality was 14 per cent (n = 7) with nine in-hospital deaths. Of 30-day survivors 29 (60%) had curative resection (21 with local perforation and nine with proximal perforation). Of these 14 received adjuvant chemotherapy. Eleven patients (33%) had either unresectable or metastatic disease on exploration. Mean follow-up was 21.5 months. Ten patients developed metastatic disease after potentially curative resections. Of these nine patients had perforations of the primary tumor. Three patients developed local recurrence and all had local tumor perforations. One-year survival was 55 per cent (n = 16). Five-year disease-free survival was 14 per cent (n = 4). There were no long-term survivors after perforation proximal to the tumor, although disease stage was comparable in both groups. We conclude that perforation proximal to a cancer is associated with a higher perioperative mortality and worse long-term outcome when compared with acute perforations at the site of the tumor. Long-term survival requires both aggressive management of the concomitant sepsis and definitive oncologic surgery.

We describe a case of adenomatous polyp of the colon that harbored small foci of signet ring cell carcinoma. The patient was a 64-year-old woman with end-stage renal disease and sepsis who underwent colonoscopy to evaluate the possibility of pseudomembranous colitis. A polyp was found incidentally in the right colon and a biopsy was performed. Histologic examination of the polyp revealed typical features of tubular adenoma without evidence of high-grade dysplasia. However, 2 small foci of signet ring cell carcinoma were identified that infiltrated the lamina propria. In contrast to adenomatous epithelium, the signet ring cells were immunohistochemically positive for cytokeratin 7 and negative for cytokeratin 20, suggesting a metastasis rather than a primary tumor. Multiple random biopsies from the right and left colon, as well as the ileum, exhibited no histologic evidence of malignancy. Subsequently, signet ring cell carcinoma with similar morphology and identical immunophenotype was detected in biopsies from the endometrium, an unusual location for primary signet ring cell carcinoma. Preliminary workup excluded the breast as a possible primary site, but further investigation was not possible because of the patient's death with no autopsy granted. To the best of our knowledge, this is the first reported case of metastatic signet ring cell carcinoma to an adenomatous polyp of the colon. This case illustrates the necessity of submitting all polyps entirely and the importance of examining them carefully.

Data on 19 patients (6 women and 13 men) with malignancy perforation through small bowel tissue were retrospectively reviewed. The median patient age was 57 years (range, 41-81 years). The histopathology included lymphoma (seven patients), leiomyosarcoma (two patients), gastrointestinal stromal tumor (one patient), adenocarcinoma (one patient), metastatic carcinomas with unknown primary tumor (four patients), metastatic adenocarcinoma from the lung (one patient), and metastatic carcinomas from the hypopharynx (one patient), cervix (one patient), and lung (one patient). Resection of a segment of perforated bowel with primary anastomosis was performed in 16 patients, wedge resection of perforated lesion with plication in two patients, and loop ileostomy in one patient. Postoperative deaths occurred in 10 (52.6%) patients, owing to sepsis and organ functional failure. Seven patients died from the primary malignancy at a median follow-up of 6.5 months (range, 5 months to 1 year 9 months) after surgery. Moreover, two patients with small bowel lymphoma were alive with disease at 4 years 8 months and 7 years 1 month after surgery. In conclusion, perforation through small bowel malignant tumors had a high postoperative mortality rate. High index of suspicion of the disease with early surgical treatment may improve treatment outcomes.

Six patients with advanced oral squamous cell carcinoma were treated with preoperative concurrent chemoradiotherapy. Chemotherapy consisting of CDDP(60 to 70 mg/m(2), day 1)and 5-FU(600 to 700 mg/m(2), day 1 to 5)with concurrent radiotherapy was accelerated hyperfractionation to target volume of 43-63 Gy. The clinical effect of this therapy on the primary tumor and cervical lymph node was examined in patients who visited our university hospital from 1994 to 2004. The five untreated and one recurrence patients were 3 males and 3 females. Their ages ranged from 23 to 76 years. The primary sites were the tongue in 3, lower gingiva in 2, and upper gingiva in 1 patient(s). Five cases were in advanced Stage IVA and 1 case in Stage III. The preoperative clinical responses of primary tumor: 1 case showed a complete response(CR). The response rate was 100%. We did not operate the case because of CR. Histological effect of the primary tumor(according to the grading system of Ohboshi and Shimosato): 2 patients were CR. Pathological CR rate of primary site was 33%. However, the CR rate of the metastatic lymph nodes was 0%. In terms of adverse effects, all cases developed nausea, mucositis and leucopenia. The most severe were leucopenia(Grade III), sepsis and DIC. This combination chemoradiotherapy has been proven to be very histologically effective for the primary tumor.
