Gastric adenosquamous carcinoma producing granulocyte-colony stimulating factor

We report a case of adenosquamous carcinoma of the stomach that produced granulocyte-colony stimulating factor (G-CSF). The patient, who had an admission diagnosis of advanced gastric cancer, had marked leukocytosis without evidence of infection. After leukemia and metastatic leukemoid reaction were excluded by bone marrow examination, a G-CSF-producing cancer was suspected as the cause of the abnormally elevated serum G-CSF level. The resected stomach tumor was histologically diagnosed as adenosquamous carcinoma; positive expression of G-CSF by tumor cells was shown with immunohistochemical detection, which confirmed the preoperative diagnosis. Recurrent disease in the liver and lymph nodes, accompanied by leukocytosis and re-elevation of serum G-CSF, developed just 3 months after the curative gastrectomy and adjuvant chemotherapy. All of the recurrent disease was resected, restoring normal levels of serum G-CSF. The patient survived for almost 2 years after the initial surgery with extensive chemotherapy, including weekly treatment with paclitaxel, before finally succumbing to liver failure secondary to extensive liver metastasis.     

Factors that affect early postoperative health-related quality of life in patients with gastrointestinal cancer: a three-center cohort study

[Purpose] In this study, we investigated the preoperative and early postoperative health-related quality of life in patients who underwent surgical treatment for gastrointestinal cancer and also the factors that affect postoperative health-related quality of life. [Participants and Methods] The study included 198 patients who underwent elective surgery for gastrointestinal cancer (129 males and 69 females, age: 65.4 ± 11.8 years). Health-related quality of life was evaluated using the Short-Form 36-Item Health Survey version 2 at the following time points: 1–2 days preoperatively (baseline) and 4 weeks postoperatively. [Results] Compared with baseline levels, physical functioning, bodily pain, vitality, as well as physical, social, and emotional role functioning significantly decreased 4 weeks postoperatively. In contrast, compared with baseline levels, mental health significantly improved 4 weeks postoperatively. Physical functioning and general health evaluated 4 weeks postoperatively were significantly associated with income, baseline health-related quality of life, and the 6-minute walk test. [Conclusion] It is important to consider baseline income and health-related quality of life and increase postoperative exercise capacity to improve health-related quality of life in patients who undergo surgical treatment for gastrointestinal cancer.     

A new device for MRI-guided surgical excision: report of a case

A 37-year-old female was indicated to have a non-mass lesion in her left breast on ultrasonography (US) and visited our outpatient clinic. Mammography showed no findings of masses or microcalcification. Dynamic magnetic resonance imaging (MRI) showed a segmental enhanced lesion consisting of nodular and ring enhancement. A US-assisted vacuumed needle biopsy was performed, and the histological findings revealed sclerosing adenosis and apocrine metaplasia. After 1 year of follow-up, the MRI findings suggested both a benign lesion and ductal carcinoma in situ, and surgical excision was performed. We used a new device to evaluate the surgical margin on MRI. The non-mass lesion was excised according to the device-guided margin under local anesthesia. The histological findings revealed the features of mastopathy. Following excision, MRI showed no residual non-mass lesions, and the shape of the patient’s left breast was maintained.     

Partial splenic embolization prior to combination therapy of interferon and ribavirin in chronic hepatitis C patients with thrombocytopenia

Aim: A low platelet count leads to dose reduction of interferon (IFN) and is associated with failure to achieve a sustained virological response (SVR) in chronic hepatitis C patients. However, partial splenic embolization (PSE) is effective for treating thrombocytopenia resulting from hypersplenism. Methods: We compared the clinical features of 10 patients receiving PSE prior to the combination therapy of IFN and ribavirin (RBV) (PSE group) with those of 10 non‐receiving PSE patients (non‐PSE group). Results: In all 10 patients, PSE was successfully performed without serious adverse events. After PSE, leukocyte, neutrophil, and platelet counts significantly increased. The period from PSE to the initiation of the combination therapy was 15 (7–21) days. In the PSE group, two of six patients (33%) infected with genotype 1, and all four patients infected with genotype 2, achieved SVR. In the non‐PSE group, only three patients infected with genotype 2 achieved SVR. Two patients in the PSE group and one in the non‐PSE group discontinued the combination therapy. Three patients of the PSE group and five of the non‐PSE group reduced the dose of pegylated IFN‐α‐2b because of thrombocytopenia. In the PSE group, platelet counts during the combination therapy fell to baseline levels; however, they did not fall to lower levels than baseline levels. In the non‐PSE group, platelet counts 1 month after the initiation of the therapy were lower than baseline levels. Conclusion: The increase of platelet counts after PSE may allow the safe use of IFN and RBV and improve the SVR rate in chronic hepatitis C patients with thrombocytopenia.

Pediatric myositis ossificans mimicking osteosarcoma

Myositis ossificans (MO) is a rare benign cause of heterotopic bone formation in soft tissue that most commonly affects young adults, typically following trauma. We report the case of an 11‐year‐old girl who developed MO mimicking osteosarcoma in her right shoulder. Plain radiography and computed tomography showed poorly defined flocculated densities in the soft tissue and a periosteal reaction along the proximal humerus. On magnetic resonance imaging, the mass displayed an ill‐defined margin and inhomogeneous signal change. Histologically, the mass had a pseudosarcomatous appearance. Based on these findings, the patient was initially misdiagnosed with osteosarcoma at another hospital. The diagnosis was difficult because the patient was 11 years old and had no trauma history, with atypical radiographic changes and a predilection for the site of origin for osteosarcomas. We finally made the correct diagnosis of MO by carefully reviewing and reflecting on the pathological differences between stages.     

Is admission hyperglycaemia in non-diabetic patients with acute myocardial infarction a surrogate for previously undiagnosed abnormal glucose tolerance?

AIMS: To investigate whether admission hyperglycaemia in non-diabetic patients with acute myocardial infarction (AMI) is a surrogate for previously undiagnosed abnormal glucose tolerance. METHODS AND RESULTS: Two hundred non-diabetic patients with AMI were divided into three groups: 81 patients with admission glucose < 7.8 mmol/L (group 1), 83 patients with admission glucose > or = 7.8 mmol/L and < 11.1 mmol/L (group 2), and 36 patients with admission glucose > or = 11.1 mmol/L (group 3). Abnormal glucose tolerance, diabetes, or impaired glucose tolerance (IGT) was diagnosed by oral glucose tolerance test (OGTT). OGTT identified diabetes in 53 patients (27%) and IGT in 78 patients (39%). When the fasting glucose criteria were applied, however, only 14 patients (7%) were diagnosed as having diabetes. The prevalence of abnormal glucose tolerance was similar among the three groups: 67% in group 1, 63% in group 2, and 69% in group 3 (P = 0.74). The relation of fasting glucose (r2 = 0.50, P < 0.001) and HbA1c (r2 = 0.34, P < 0.001) to 2-h post-load glucose was significant, but the relation of admission glucose to 2-h post-load glucose was not significant (r2 = 0.02, P = 0.08). Multivariable analysis showed that fasting glucose and HbA1c were independent predictors of abnormal glucose tolerance, but admission glucose was not. CONCLUSION: Admission hyperglycaemia in non-diabetic patients with AMI does not represent previously undiagnosed abnormal glucose tolerance. Fasting glucose and HbA1c, rather than admission glucose, may be useful to predict abnormal glucose tolerance. However, these parameters lacked sensitivity. OGTT should be considered in all non-diabetic patients with AMI.
