ABSTRACT

Metastasis from lung cancer to the small bowel is rare and this accounts for 0.2% to 0.5% of all the cases of metastasis from lung cancer. In most cases, the patients are asymptomatic and they can show signs of bleeding, intestinal obstruction, perforation and so on. A better diagnostic approach to the small bowel has recently been made possible through capsule endoscopy and double balloon enteroscopy (DBE), and they have a higher diagnostic rate for small bowel bleeding compared with that of the previous diagnostic tests. DBE makes it possible to diagnose precisely due to the high quality endoscopic images and biopsy specimens. In addition, therapeutic DBE with a 2.8 mm channel enables performing more kinds of therapeutic procedures than diagnostic DBE with a 2.2 mm channel. If small bowel metastasis is suspected on 18FDG-PET/CT, then DBE can be considered for making a pathologic diagnosis. We report here on a case of small bowel metastasis from non small cell lung cancer in a 39-year-old woman who complained of hematochezia and we review the relevant literature.

ABSTRACT

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci. However, liver abscess caused by Salmonella species has rarely been reported. We experienced a case of Salmonella liver abscess which improved after antibiotic therapy and percutaneous drainage. The patient was 52 years-old man who had an episode of intermittent fever, chills and epigastric pain for 2 weeks. He was diagnosed as liver cirrhosis eight years ago and diabetes three years ago. Salmonella group D, non-typhi was cultured from blood and pus from the liver respectively at the same time. With percutaneous drainage and susceptible antibiotic therapy, liver abscess decreased in size with improvements in fever and abdominal pain.

ABSTRACT

BACKGROUND/AIMS: Advanced hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) has a poor prognosis. The aim of this study was to evaluate the efficacy and safety of repeated arterial infusions of low dose cisplatin and 5-fluorouracil (FU) in patients with advanced HCC with decompensated cirrhosis. METHODS: Between January 1995 and December 2003, a total of 79 decompensated cirrhotic patients having HCC and PVT were enrolled and divided into 2 groups. Group 1 (n=40) received intra-arterial infusion chemotherapy with cisplatin (10 mg for 5 days) and 5-FU (250 mg for 5 days) via an implanted chemoport every 4 weeks' and group 2 (n=39) was managed with only conservative treatment. RESULTS: The two groups were well matched with respect to the features relating to the prognosis, including age, gender and the Child- Pugh class. Although diffuse tumor involvement, main portal vein tumor thrombosis and bi-lobar involvement were more frequent in group 1, the median survival period of group 1 was significantly longer than group 2 (5 months vs. 3 months, respectively, P=0.016). Also, the 1-year survival rate of group 1 (7.5%) was higher than that of group 2 (5.1%) (P=0.016). When we analyzed the patients with the Child class B, the survival benefits of intra-arterial chemotherapy were more significant (P=0.008). CONCLUSIONS: Intra-arterial chemotherapy consisting of low dose 5-FU and cisplatin achieved favorable results for advanced HCC patients who had decompensated cirrhosis, and it showed better survival in selected patients. This therapy may be useful as a palliative treatment for HCC patients with decompensated cirrhosis.

ABSTRACT

BACKGROUND/AIMS: The aim of this study was to compare the patient's satisfaction and tolerance of transnasal (TN) and transoral (TO) endoscopy prospectively. METHODS: 120 patients were assigned to undergo TN (age: 49.5, M : F=65 : 55) or TO (age: 47.4, M : F=63 : 57) endoscopy according to their wishes. RESULTS: The patients' satisfaction was higher in the TN group than in the TO group (8.45 vs. 4.95, p <0.05). The degree of choking sensation, nausea, and throat soreness was lower in the TN group than the TO group. There was no difference in endoscopists' satisfaction between the two groups. The duration for TN was longer than for TO. Epistaxis and nasal pain were the common complications in the TN group. All complications were mild and were relieved spontaneously. An endoscopic examination could be completed in all patients in the TO group. In the TN group, examination failure was quite common in the early phase but the incidence decreased with increasing experience. It took the experience of at least 20 cases for the endoscopist to adapt to the TN route. CONCLUSIONS: TN endoscopy is believed to be a comfortable and safe procedure for improving the patients' satisfaction and for reducing the level of inconvenience.

ABSTRACT

BACKGROUND: We performed a phase II study to determine the activity and toxicity of Navelbine, Ifosfamide, and Cisplatin (NIP) combination in patients with stage IIIB-IV non-small cell lung cancer (NSCLC). METHODS: Thirty-two chemotherapy naive patients were enrolled from 2 centers between February 1997 and December 1997. The median age was 57 years (range, 29-71); stage IIIB/IV 6/26;male/female 23/9. The regimen consisted of navelbine (25 mg/m2 day 1 and 5), ifosfamide (3 g/m2 day 5 with uroprotective mesna), and cisplatin (80 mg/m2 day 5) every 3 weeks. RESULTS: Twenty-six were evaluable for response and 31 for toxicity. One patient was lost to follow up, one patient refused to continue, and 4 patients could not continue due to poor performance. Total of 120 cycles have been given, with median of 4 cycles per patient (range; 1-6). Sixteen patients achieved partial response (response rate on an intention-to-treat basis, 50%; 95% C.I:32-68%). Neutropenia was the most common toxicity. Grade III-IV neutropenia was observed in 39% of courses; thrombocytopenia 4% of courses; anemia 14% of courses. Three patients developed febrile neutropenia; there was no treatment-related death. The median time to progression was 6.9 months and the median overall survival 8.0 months. The probability for 1-year survival was 25%. CONCLUSION: The NIP combination has promising activity and acceptable tolerance in advanced NSCLC patients. But modification of schedule is necessary to increase compliance or dose intensity of navelbine.

ABSTRACT

PURPOSE: To evaluate the efficacy and safety of gemcitabine, a pyrimidine antimetabolite against advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Forty patients with unresectable stage IIIb to IV, pathologacally documented NSCLC were evaluated. Patients received gemcitabine 1000 mg/m, as a 30 to 60-min, intravenous infusion on days 1, 8 and 15, which was repeated every 28 days. Responses were assessed every two courses. Twenty-five to fifty percent dose reduction was permitted, ptovided that overall toxicity was severe according to World Health Organization (WHO) toxicity criteria. RESULTS: Of all 40 patients (32 men, 8 women; age range 37 to 73 years; median 63 years), 3S patients were assessable for response. 15 patients had stage IIIb disease and 25 had stage IV. Nineteen patients were histologically classified as adenocarcinoma (47.5%), 17 as squamous cell carcinoma (42.5%), 1 as large cell carcinoma (2.5%), 1 as mixed carcinoma (2.5%) and 2 as undifferentiated carcinoma (5.0%). The overall response rate was 20%. None of the patients showed complete response while 7 showed partial response (20%), 5 had stable diseases (23%) and 23 had progressive diseases (57%). During a total of 119 courses, hematologic toxicity was negligible. Granulo- cytopenia worse than WHO grade 3 occured in 11.8%, anemia in O.S% and thrombocytopenia in 0.8%, respectively. Non-hematologic toxicity was minor and easily controlled. There was no case of febrile neutropenia or treatment-related death. CONCLUSION: The single agent efficacy of gemcitabine is comparable to other agents commonly used to treat NSCLC. Gemcitabine has unusually mild side effect profile for such an active agent. This significant activity in conjunction with a very favorable toxicity profile supports further investigation in combination with other agents in patients with inoperable NSCLC.

ABSTRACT

OBJECTIVES: The reported success rate of central venous catheterization ranged from 84% to 97.5%, and the complication rate from 0.3% to 12%. The most important contributing factor for complications reported by several authors was the physician's experience. We investigated the success and complication rates of central venous catheterization prospectively. We also evaluate the factors that contributed to complications at our institution as part of our quality assurance study. METHODS: Four hundred sixty five central venous catheterizations were conducted at the medical intensive care unit and the general ward of the hematology/ oncology Department of Asan Medical Center in Korea, from June to November, 1997. We surveyed the date and place of the procedures, ID numbers, age and sex of the patients, the training level of physicians, the types of catheters, initial puncture sites, success or failure, and complications. We grouped the purpose of procedures into 5 categories, such as hemodynamic monitoring, fluid therapy, chemotherapy, total parenteral nutrition, and others. RESULTS: The initial success rate, defined as the initial performer being able to insert the catheter without changing the skin puncture site, was 78.5%. The overall success rate for initial performers, including those who required multiple skin puncture sites, was 82.8%. The total success rate, including changing the performers (up to 4 performers), was 96.1%. The overall complication rate was 5.2% including pneumothorax (2.8%), hemothorax (0.2%), subcutaneous hematoma (1.1%), catheter tip malposition (0.9%), and air-embolism (0.2%). There were no differences in the complication rates with regards to the sex and age of the patient, initial puncture sites, the physician's training level between 1st and 2nd year residency, and vein localization. However, the complication rate differed significantly in relation to the number of initial punctures. Patients with 1-3 punctures had a complication rate of 4.3%, while patients with 4 or more punctures had a complication rate of 18.5%. CONCLUSION: The overall complication rate was 5.2% and pneumothorax occured in 2.8%. We expect that we can decrease the number of complications by taking over the procedure if the initial performer fails on the first or second attempt and by attempting the skin puncture not more than 4 times at initial trial.

ABSTRACT

OBJECTIVES: The advent of intense combination chemotherapy has transformed aggressive non-Hod-gkins lymphoma from a disease that was once uniformly fatal to one that is now often curable. Remission rates and survival may be improved by using intensive chemotherapy regimens. However, this more aggressive approach is inevitably associated with increased toxicity, and an accurate pretreament prognostic assessment of patients is required to guide the physician in selecting the most appropriate therapeutic regimen. Many studies have reported prognostic factors of non-Hodgkins lymphoma in western countries, but there are few reports on prognostic factors in Koreans and it is suggested that clinical characteristcs of non-Hodgkins lymphoma in Korea differ from those in western countries. The purpose of this study was to illustrate clinical characteristics, prognostic factors and treatment outcome in non-Hodgkins lymphoma in Korea. METHODS: Clinical features of 151patients (age over 15years) with non-Hodgkins lymphoma registered at Asan Medical Center from March 1989 to December 1993 were retrospectively reviewed. Prognostic factors and treatment outcome were evaluated among 121previously untreated patients. Multi variate analysis of potential pretreatment prognostic factors was performed using Coxs proportional hazards model. RESULTS: Of the 151patients evaluated, 55% had diffuse large cell type, while low-grades were encountered in less than 1% of the patients. Extranodal involvement was noted in 76% of the patients. Cental nervous system was the commonest primary extranodal site, followed by stomach. Complete remission was achieved in 73 of 121patients (60%). The median follow-up for 121patients was 24months and the actuarial overall survival was 48% at 3years and 44N at 5years with a median overall survival of 33months. At the median followup of 32months, the actuarial 5year disease-free survival rate among 73patient with complete remission was 65% and median remission duration was not reached. Presence of systemic B symptoms and advanced clinical stages were associated with a low complete remission rate. None turned out to be associated with the remission duration. The Coxs proportional hazards model identified age above 60years, presence of systemic B symptoms and elevated LDH level as significant independent poor prognostic factors influencing overall survival. CONCLUSION: This study reveals a low prevalence rate of the low-grades lymphoma and a higher propensity of diffuse large cell type. These results suggest that clinical characteristics of non-Hodgkins lymphoma in Korea are different from those in the western countries. Our data also show that certain pretreatment clinical factors can help in predicting survival and in planning treatment.

ABSTRACT

Lymphomatous involvement of the heart, occurring at initial diagnosis and presentation, is extremely rare. We report here a case of 58 year old man who presented with generalized edema, pericardial effusion, and a large right atrial mass detected by transesophageal echocardiography. There is no other evidence of disseminated lymphoma in this patient. Tumor removal and pulmonary embolectomy was done. Pathologically, the mass was malignant lymphoma, diffuse large cell type. Unfortunately, we have no chance to perform the intensive chemotherapy. The patient discharged in moribund state.

ABSTRACT

We observed clinical and histopathological findings of porokeratosis in 16 cases which comprised 2 linear types, 4 superficial disseminat:ed forms, 4 disseminated superficial actinic porokeratosis and 6 plaque types. From the observation, the following results were obtained. l. Clinical results 1) Eleven cases were men, 5 cases were women, and the sex ratio was 2. 2 to 1, age distribution was from 6 to 61 years (mean age: 34. 2years), and the distribution of age of onsets was from 2 to 52 years(mean age of onset' 23. lyears). 2) Four cases had family history of porokeratosis, but linear forms did not. 3) Nine cases had pruritus especially, all cases of DSAP and DSP except 1 case complained pruritus. 4) Tmo cases of DSAP had tendency of summer exacerbations. 2. Histopathological results 1) Cornoid lamellae were prominent in all cases of plaque types and linear types, and minimal in all cases of DSAP and DSP except 1 case. 2) Epidermis between the cornoid lamellae were normal or acanthotic in all cases except 1 case of plaque types and linear types, and were atrophic in 5 cases of 8 cases in DSAP and DSP.

ABSTRACT

We report a case of Waardenburgs syndrome in 18-year-old male patient who has total deafness of the right ear, heterochromia irides, hypopigmented patches on the face and trunk, and disseminated lentigines on the entire body surface since birth. His 51-year-old mother also has total deafness, heterochromia irides, white foreloek, and disseminated lentigines on the entire body surface. The patient with this disorder may complain of pigmentary abnormalities, and we believe dermatologists should pay more attention to systemic signs of the congenital pigmentary disorders.
