We have evaluated the radioimmunoassay for type I procollagen carboxy terminal peptide (type I C-peptide), which is liberated from type I procollagen during its conversion to collagen, in the serodiagnosis of scirrhous carcinoma of the stomach. The mean (SD) serum concentration of type I C-peptide in 39 normal subjects was 41.7 (19.7) ng/ml. The mean serum values and the positive ratio of type I C-peptide in 11 patients with stages II and III scirrhous carcinoma of the stomach were 91.2 (41.9) ng/ml and 54.5%, respectively. In 10 patients with other types of gastric carcinoma, the mean type I C-peptide values were not significantly different from the normal value. Serum type I C-peptide values reflected the clinical course of scirrhous gastric carcinoma in five patients who underwent either operation or chemotherapy. The measurement of serum type I C-peptide concentrations could provide a useful way of diagnosing and monitoring scirrhous carcinoma of the stomach. 相似文献

BACKGROUND/AIMS: Surgical resection of hepatic or pulmonary metastases from gastrointestinal cancer has been recognized as a curative modality in some patients. However, the role and outcome of the surgical management of a non-hepatic intraabdominal recurrence of gastrointestinal cancer have not been clearly delineated. METHODOLOGY: We treated 5 patients for non-hepatic intraabdominal recurrence of gastric carcinoma surgically. All the resected specimens were microscopically identified as recurrent gastric cancer. Three of 5 patients received postoperative chemotherapy. The clinicopathological findings were analyzed according to the general rules for gastric cancer study. RESULTS: The lymph nodes were dissected for lymph node metastases. Surgical resection of the tumors combined with total gastrectomy, esophagectomy, or colectomy was performed for the local and peritoneal recurrences. All of the recurrent tumors were macroscopically resected with curative states. One patient died of sepsis 54 days after surgery. Three patients died of recurrent gastric cancer: 2 within 1 year of surgery and 1 after 3 years. One patient still survives disease free 3 years and 6 months after the 2nd operation. CONCLUSIONS: Surgical resection for non-hepatic intraabdominal recurrence of gastric cancer is the treatment of choice for selected patients. Surgical resection followed by adjuvant chemotherapy may improve the outcome of these patients. 相似文献

A 59-year-old man with a six-month history of chronic myelomonocytic leukemia (CMML) was admitted to the Kitasato University Hospital because of melena in September 2000. Colonofiberscopy and barium enema demonstrated an ulcerated tumorous lesion in the transverse colon. The histopathologic findings of the ulcer bed revealed diffuse infiltration of granulocytes at each stage of differentiation. The diagnosis of granulocytic sarcoma (GS) was made. Surgical resection was not indicated, because thrombocytopenia was hardly improved enough to allow surgery despite repetitive transfusion of platelet concentrates. CMML developed to refractory anemia with excess of blast in transformation in February 2001. Two courses of low dose cytarabine plus aclarubicin were ineffective on the GS in spite of a decrease in the peripheral blood blasts. Progression to acute myeloid leukemia eventually broke out, in July 2001. The patient died of leukemia complicated with pneumonia and intestinal obstruction. At present, nine cases of GS in the colon have been reported. However, these cases did not include CMML. This is the first report describing GS in the colon associated with CMML. 相似文献

An 85-year-old woman with no history of abdominal surgery complained of abdominal pain and vomiting and was referred to us with a diagnosis of intestinal obstruction a few days later. Upon admission to our facility, she presented with marked abdominal swelling and prominent kyphosis. Because of the kyphosis, most of the dilated bowel was compressing her thoracic cavity. No obvious strangulation or free air was observed via abdominal computed tomography imaging. We attempted decompression using a nasogastric tube, but the symptoms persisted. Surgery was performed 2 days after admission. The origin of the obstruction was a compression of the ileocecal region by the costal arch. The bowel was discolored, and thus surgically excised. There were no major postsurgical complications other than a mild wound infection. Until now, there have been no reports of advanced kyphosis inducing ileus, but there are concerns of an increase in similar cases as society continues to age. 相似文献

Philadelphia chromosome-positive mixed phenotype acute leukemia (Ph+MPAL) is a rare type of acute leukemia having myeloid and lymphoid features. In the present study, we describe the successful treatment of a 71-year-old Japanese female patient with Ph+MPAL by the alternation of second-generation tyrosine kinase inhibitors according to BCR-ABL1 mutations. The patient survived in her third complete remission (CR) for over 4 years. In her first CR, the patient was treated with multiple-agent chemotherapy and underwent maintenance therapy with imatinib and monthly vincristine and prednisolone (VP). At the first relapse, an examination of the bone marrow revealed a transformation into acute lymphoblastic leukemia and an F317L mutation in BCR-ABL1 gene, which responded preferentially to nilotinib over dasatinib. She achieved second CR, and nilotinib with VP therapy was selected for maintenance treatment. At second relapse, BCR-ABL1 mutational analysis revealed Y253H mutation instead of F317L mutation, resulting in resistance to nilotinib. The patient achieved third CR with dasatinib and VP therapy, and maintained CR with this treatment. This suggests that appropriate alternation of TKIs may contribute to long-term survival in elderly patients with Ph+MPAL. 相似文献

A 36-year-old woman without overt coronary risk factors was admitted to hospital with coma about 9 hours after mass self-injection of insulin (1,500 units). Laboratory investigation revealed severe hypoglycemia and hyperinsulinemia. During the treatment of her hypoglycemia, circulatory collapse occurred. The ECG, echocardiogram, and elevation in troponin T suggested a diagnosis of myocardial infarction. Although the patient became apallic and developed systemic spasticity due to hypoglycemic brain damage, her hemodynamics improved with supportive care alone. Coronary angiography and myocardial scintigraphy performed later demonstrated a broad area of myocardial damage despite intact coronary artery circulation. The authors hypothesize that temporary coronary arterial narrowing or coronary arterial vasospasm induced by severe hyperinsulinemia contributed to the pathogenesis of the myocardial infarction. The possibility of myocardial infarction should be considered in patients with acute insulin poisoning. 相似文献

In order to discover the HLA DR antigens linked to Japanese insulin-dependent diabetes (IDDM), and to relate them to the clinical features, HLA DR antigens were examined in 75 IDDM patients including 56 adult-onset cases. Among the tested HLA DR antigens, 4, w9 and w13 were significantly more frequent in IDDM (55%, 47% and 27% respectively). The relative risk was 1.71 for DR4, 2.81 for DRw9 and 4.74 for DRw13. DR2 was significantly less frequent and the relative risk was 0.14. The distribution of DR antigens did not differ between juvenile-onset and adult-onset IDDM, males and females, or cases with and without thyroid autoantibodies. Homozygotes for DRw9 were, but those for DRw13 and DR4 were not more frequent than expected by a random combination. Heterozygotes for DR4 and w9 were less frequent while other heterozygotes for high-risk antigens were as frequent as expected. 97% of IDDM had either DR4, w9 or w13. In conclusion, HLA DR4, w9 and w13 were significantly increased in patients with both juvenile- and adult-onset IDDM. There was no surplus increase in the frequency of IDDM patients with two high-risk HLA DR antigens, more than expected from random combination of each of these DR antigens. Clinical features did not differ among IDDM patients with each of these three antigens. 相似文献

A 56-year-old Japanese man in whom a descending colon carcinomahad been resected underwent a high orchitectomy for metastaticepididymis from the colon. Metastatic carcinoma from the digestiveorgans to the spermatic cord (SC) and/or the intrascrotal contents(ISC) is rare. Fifty-four Japanese patients with metastasisfrom the digestive organs to the SC and/or the ISC were analyzed.The most frequent primary site was the stomach and the mostfrequent metastatic site was the spermatic cord. Our patientwas the first to exhibit metastasis from the colon to the epididymis.A primary site was identified in 24 patients subsequent to themetastatic tumor. Twenty patients had other organ metastatis.The prognosis for SC and/or ISC metastasis patients is poor.Our patients has survived for 18 months following his orchitectomywith no other organ metastasis (31 months after the primaryoperation). In our patient, monoclonal estrogen receptor stainingwas negative; however, further study must be undertaken. 相似文献
