Small bowel hemangioma is a rare benign lesion, and it usually presents with bleeding or as a leading point of an intussusception. However, obstruction due to intramural hematoma by this lesion is unusual. Intramural hematoma of the duodenum is also an uncommon lesion, and it is usually a complication of blunt abdominal trauma in children and young adults. We present here a case of an intramural hematoma that was caused by spontaneous bleeding of a hemangioma, and this caused duodenal obstruction.
Purpose: The detection of occult micrometastasis in breast cancer patients may allow the establishment of prognosis and development of new therapeutic approaches. This study was performed in order to improve on existing methods of detection by evaluating the potential of specific mRNA markers in reverse-transcriptase polymerase chain reaction (RT-PCR) of peripheral blood and bone marrow taken from patients with breast cancer. Methods: Peripheral blood and bone marrow samples were obtained from thirty-four breast cancer patients who undergone surgery in the Department of Surgery, Uijongbu St. Mary's Hospital between January 2000 and May 2001. In RT-PCR, we tried multiple primers on breast cancer cell lines and patient samples. Using MUC-1 and CK19 mRNA primers, we detected micrometastasis in breast cancer patients. Subsequently, we analysed the correlation with RT-PCR results and other prognostic factors. Results: MUC-1 and CK19 were detected in all breast cancer cell lines. However, CEA was not detected in some cell lines. CK19 showed greater sensitivity than MUC-1 in RT-PCR. Using MUC-1 as primers, the detection rate was 47.1% and 35.3% in bone marrow and peripheral blood, respectively. Seven patients (20.5%) were positive in both sources. In the case of CK19, the detection rate was 50% and 41.2% in bone marrow and peripheral blood, respectively. Twelve patients (35.2%), were noted as being positive for both primers. The concordance rate of both primersmers was 38.2% and 23.5% in bone marrow and peripheral blood, respectively. CK19 positivity in the peripheral blood was correlated with bone marrow positivity and MUC-1 positivity in both sources and inversely correlated with ER. CK19 positivity of bone marrow was correlated with MUC-1 positivity of bone marrow. Conclusion: CK19 and MUC-1 may be good candidates for use in RT-PCR for the detection of micrometastasis of breast cancer. CK19 showed greater sensitivity. However, using both primers in RT-PCR, we may detect micrometastasis more sensitively and specifically and more wisely choose a treatment modality.
We present a case of xanthogranulomatous cholecystitis which involved the liver and clinically mimicked gallbladder carcinoma, and review the associated literature. A 72-year-old woman was admitted to our hospital because of intermittent, right upper quadrant, abdominal pain. Computed tomography showed a large-mass in the gallbladder with findings that seemed to indicate invasion of the liver. During laparotomy, the gallbladder showed signs of chronic cholecystitis, and a cholecystectomy was performed. Histopathological diagnosis was xanthogranulomatous cholecystitis.
Purpose: The most important prognostic factors in gastric cancer are depth of invasion and lymph node metastasis. Therefore, the prognosis for serosa and lymph node negative gastric cancer is favorable. However, there is no general agreement on the prognostic factors in this subset of patients. This study was undertaken to evaluate the prognostic significances of venous invasion (VI), lymphatic invasion (LI), and perineural invasion (NI) in T1 and T2 gastric cancer without lymph node involvement. Materials and Methods: We retrospectively evaluated 206 patients with T1 and T2, lymph node negative gastric cancer who underwent a curative resection from 1989 to 1993 at Kangnam St. Mary's Hospital, Seoul, Korea. The Chi-square test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rates were assessed using the log-rank test, and the Cox regression method was used to evaluate independent prognostic significance. Results: The rate of VI, LI and NI correlated well with the depth of tumor invasion. The rates of VI (+) for T1 vs T2 was , of LI (+) was , and of NI (+) was in NI (+). There were 13 recurrent cases, 10 cases out of the 13 were T2 gastric cancers, and the recurrence rate was higher in LI (+) and NI (+) cases than in LI (-) and NI (-) cases. The 5-year survival rates were in LI (-) cases, in LI (+) cases, in NI (-) cases, in NI(+) cases, in LI (-) NI (-) cases, and in LI (+) NI (+) cases. Multivariate analysis demonstrated that simultaneous LI and NI was the only significant factor influencing the prognosis. Conclusion: These results suggest that simultaneous lymphatic and perineural invasion may be an independent prognostic factor in patients with T1 and T2 gastric cancer without lymph node metastasis.
We report a rare case of inflammatory fibroid polyp of the stomach that mimicked gastric cancer. A review of the associated literature is also reported. A 32 year old woman was admitted to our hospital with a history of vomiting and epigastric pain and a weight loss of 10 kg in one month. A radiologic and an endoscopic examination showed a protruding tumor, with diffuse ulceration at the posterior wall of the prepyloric antrum of stomach. Although no malignant cells were histologically confirmed in the biopsy specimens, a subtotal gastrectomy, with a lymphadenectomy, was performed because gastric cancer was suspected, preoperatively. The histopathological diagnosis was an inflammatory fibroid polyp of the stomach. If a submucosal tumor of the stomach is suspected in a preoperative diagnosis, an inflammatory fibroid polyp should be considered as one of the possible differential diagnoses.
Purpose: Bone metastasis is not a common event in patients with gastric cancer. Therefore, most studies of bone metastasis in such patients have been in the form of case reports, so the clinical features of the bone metastasis are not well understood. To clarify metastatic patterns, the efficacy of radiation or chemotherapy, and the prognosis, we analyzed 29 cases of patients with bone metastases after curative surgery for gastric cancer. Materials and Methods: Twenty-nine (29) gastric cancer patients with bone metastasis who underwent curative resection from January 1989 to December 2002 at the Departments of Surgery, Kangnam St. Mary's Hospital and Our Lady of Mercy's Hospital, The Catholic University of Korea, were analyzed. Results: Nineteen (19) patients were males and, 10 patients were females. The mean age of the patients was years. There were more Borrmann type-3 and type-4 cancers and more undifferentiated histologic types. Most of the original cancers were stage III or IV. The most frequently involved bone was the spine. Treatment after recurrence was done in 16 patients (). The median survival time after recurrence of the patients who received treatment was seven (7) months ( months in range), which was significantly longer than that of the patients who did not received treatment (P=0.019). However, there was no difference according to the treatment modality (P=0.388). Conclusion: Bone metastasis after a curative resection of gastric cancer tends to occur in Borrmann type-3 and type-4 cancers, cancers with undifferentiated histology and, in stage III/IV disease. The prognosis of bone metastasis is dismal, and aggressive treatment is the only way to prolong survival.
