PURPOSE: As a new strategy to modulate drug resistance in the treatment of relapsed or refractory non-Hodgkin's lymphoma(NHL), continuos infusion of drugs has been incorporated into the chemotherapy. We conducted a phase II study to determine the activity and safety of EPOCH (etoposide, vincristine, doxorubicin, cyclophosphamide, prednisolone) chemotherapy, in which the natursl products are administered as a continuous infusion, for previously treated NHL's of intermediate grade. MATERIALS AND METHODS: EPOCH chemotherapy (etoposide 50 mg/m2/day 24 hour- continuous infusion, days 1~4, vincristine 0.4 mg/m2/day 24 hour-continuous infusion, days 1~4, doxorubicin 10 mg/m2/day 24 hour-continuous infusion, days 1~4, cyclophosphamide 750 mg/m2 i.v., day 5, prednisolone 60 mg/m2/day p.o. days 1-5) was given to eligible patients every 3 weeks and we assessed response and toxicity of the regimen. RESULTS: Between June 1993 and December 1995, total 56 patients entered this trial and 49 were evaluable. The complete response rate was 41%(95% C.I.: 27-55%). After follow up of 9~50(median 38) months, progression free survival was 0~39+(median 7) months and the overall survival was 1~44+(median 14) months. The prognostic factor analyses showed that B symtoms and serum LDH level before treatment and response to previous treatment affected complete response rate, and patients' performance status and response to previous treatment affected progression free survival and overall survival. Toxicities of EPOCH regimen were leukopenia, stomatitis, nausea/vomiting and neurotoxicity, but they were tolerable. There was 1 case of treatment-related death due to sepsis. CONDUSION: EPOCH chemotherapy was safe and effective for the patients with relapsed NHL. However, the results of patients with NHL refractory to previous treatment were so poor that more intensive, novel treatment would be needed for this category of patients.

Ganglion is the most common soft tissue tumor which occurs mainly in hand, but it can also occur in any part of the extremity. It is not always necessary to excise the tumor because it seldom cause symptoms severe enough to take operation. We reviewed the patients with ganglion treated surgically. Exculding the cases which were operated under local anesthesia and Bakers cyst, 42 patients were treated surgically from 1983 to 1992. Females were 33, and males 9. Average age at the time of operation, was 40 years (16 to 67). All the cases were analysed retrospectively in terms of surgical indication, anatomical location, size, duration of symptoms, relationship between recurrence and size, and complication. The average duration of follow-up was 1 year 7 months, ranging from 1 year to 4 years. The causes of operation were, cosmetic problem in 6996 (29 cases); pain in 19% (8 cases); and both comesis and pain in 12% (5 cases). The locations were, wrist in 4696 (19 cases); knee 29% (12 cases); foot 12% (5 cases); hand 7% (3 cases); forearm 2% (1 case); ankle 2% (1 case); and elbow 296 (1 case). The size of mass was less than 2.5 cm in 30 cases (71%), and more than 2.5 cm in 12 (29%). (Total average of size was 2.4 cm)The average duration of symptoms were 28 months (1 month 15 years). The recurrence was found in 7 cases: 3 of them (10%) occurred among 30 cases the diameter of which was less than 2.5 cm, and other four (33%) occurred among 12 cases, larger than 2.5 cm. There were no other complications.

Because the penetrating cervical tracheoesophageal injury may be associated with significant morbidity and mortality, it is important to choose the optimal method of diagnosis and management in patient with tracheoesophageal injury. We obtained a satisfactory result from repair of tracheoesophageal injuries using cardiopulmonary bypass. If the bleeding from the unidentified deep injury and the spread of infection could be controlled, the repair using CPB might increase the margin of safety during operation in the similar cases.

Background:
Numerous studies have shown the effect of particulate matter exposure on brain imaging markers. However, little evidence exists about whether the effect differs by the level of low-grade chronic systemic inflammation. We investigated whether the level of c-reactive protein (CRP, a marker of systemic inflammation) modifies the associations of particulate matter exposures with brain cortical gray matter thickness and white matter hyperintensities (WMH).
Methods:
We conducted a cross-sectional study of baseline data from a prospective cohort study including adults with no dementia or stroke. Long-term concentrations of particulate matter ≤ 10 µm in diameter (PM10) and ≤ 2.5 µm (PM2.5) at each participant’s home address were estimated. Global cortical thickness (n = 874) and WMH volumes (n = 397) were estimated from brain magnetic resonance images. We built linear and logistic regression models for cortical thickness and WMH volumes (higher versus lower than median), respectively. Significance of difference in the association between the CRP group (higher versus lower than median) was expressed as P for interaction.
Results:
Particulate matter exposures were significantly associated with a reduced global cortical thickness only in the higher CRP group among men (P for interaction = 0.015 for PM10 and 0.006 for PM2.5). A 10 μg/m3 increase in PM10 was associated with the higher volumes of total WMH (odds ratio, 1.78; 95% confidence interval, 1.07–2.97) and periventricular WMH (2.00; 1.20–3.33). A 1 μg/m3 increase in PM2.5 was associated with the higher volume of periventricular WMH (odds ratio, 1.66; 95% confidence interval, 1.08–2.56). These associations did not significantly differ by the level of high sensitivity CRP.
Conclusion
Particulate matter exposures were associated with a reduced global cortical thickness in men with a high level of chronic inflammation. Men with a high level of chronic inflammation may be susceptible to cortical atrophy attributable to particulate matter exposures.

Familial adenomatous polyposis (FAP) includes early development of up to thousands of colorectal adenoma and of colonic adenocarcinoma in all untreated cases. Moreover, a variety of extracolonic manifestation are seen. Several reports have demontrated a high incidence of papillry carcinoma of thyroid. We experienced a case of familial adenomatous polyposis, presenting with thyoid papillry carcinoma, and reported with a brief review of literatures.

BACKGROUND: Mortality and morbidity of anastomotic complications after esophagectomy have gradually decreased in recent years. However, swallowing difficulties and reflux symptoms after esophagogastrostomy continue to be a burden jeopardizing the quality of life. In the present study, we evaluated the quality of esophagogastrostomy by analyzing anastomotic stenosis and reflux esophagitis. MATERIAL AND METHOD: A retrospective analysis was made in 74 patients who underwent esophagogastrostomy after esophagectomy by one surgeon between January 1995 and December 2004. 53 patients of them received endoscopic examination during follow-up (29+/-23.6 months, range 5~111 months). Reflux esophagitis and stenosis at anastomostic site were analyzed according to the techniques and locations of esophagogastrostomy. RESULT: The median age at the time of repair was 60.3+/-8.87 years (range 39~81 years). 23 patients received a hand-sewn esophagogastric anastomosis and 30 patients a circular stapled one. There was no significant statistical difference in terms of anastomotic stenosis (p=0.64) and reflux esophagitis (p=0.41) between the two groups. Cervical anastomosis was performed in 26 patients and intrathoracic anastomosis in 27 patients. No significant statistical difference in anastomotic stenosis between the two groups was found (p=0.44), but reflux esophagitis was noted in 3 patients in the cervical anastomosis group and 14 patients in the intrathoracic anastomosis group (p=0.003). CONCLUSION: Cervical anastomosis was supposed to have a better quality of esophagogastrostomy by lowering the risk of reflux esophagitis. In the future, the comprehensive study including a patient's subjective symptom and Barrett's metaplasia should be performed in larger cases.

PURPOSE: Drug resistance is one of the major obstacles to treatment of cancer. Multidrug resistance (MDR) caused by overexpression of p-glycoprotein (Pgp) in cancer cell membrane is a well-known mechanism of drug resistance in in vitro system and was reported to be a significant mechanism of resistance in non-Hodgkins lymphoma (NHL). Verapamil, a calcium channel blocker, is proven in vitro to overcome the MDR caused by Pgp. We performed a phase II trial of verapamil in patients with NHL refractory to EPOCH regimen (etoposide, prednisolone, vincristine, cyclophosphamide, and doxorubicin) to overcome the MDR caused by Pgp. MATERIALS AND METHODS: Verapamil was administered via intravenous route from 1 hour before to 12 hour after the 96-hour infusion of etoposide, doxorubicin, and vincristine which were known to be substrates of Pgp in EPOCH regimen. The dose of verapamil was 0.15 mg/Kg in bolus and 0.2 mg/Kg/hr in infusion at the beginning and escalated by 0.05 mg/Kg/hr every 24 hours if there was no dose-limiting toxicities such as 2nd or 3rd degree AV block, hypotension, or congestive heart failure. Plasma verapamil concentrations were measured every 24 hour by gas chromatography. Mdrl expression level in tumor tissues was measured by RT-PCR. RESULTS: From Feb. to Nov. 1994, 14 patients were treated with this protocoL However, poor tolerability and no response in these patients led to early closure of the study at this 1st stage of patient accrual according to Gehans method. Among 14 patients, 12 experienced 2nd or 3rd degree AV block and/or hypotension and required temporary cessation of infusion and reduction of verapamil dose. However, there was no congestive heart failure or treatment-related death. The peak concentrations of verapamil were 0.29-1.94 pM (mean 0.93 pM) and mean concentrations during the 4-day infusion were 0.22-1.21 pM (mean 0.6 pM). Mdrl expression levels measured in 6 patients were 0.99-14.43 U (median 4.39). CONCLUSION: These results suggest that verapamil in this dose and schedule was neither tolerable nor effective for the reversal of drug resistance in NHL patients.
