A case study of pyloric stenosis caused by metastatic lobular carcinoma of breast.

Metastasis to the gastrointestinal tract is rare. A 59-year-old woman who had a history of an invasive lobular carcinoma of breast with clinical complete response visited our hospital and complained of an upper abdominal pain and distension. We performed an upper gastrointestinal endoscopy which showed only a gastric ulcer without any malignant findings. She experienced a recurrence of symptoms 2 months after this visit. An endoscopy revealed pyloric stenosis, which did not improve with balloon dilatation. We performed a gastro-jejunal and cecal-transverse colonic bypass surgery. Diffuse wall thickening of the antrum was verified during the surgery, and a biopsy sample was collected. The diagnosis of gastric metastasis from breast was confirmed since it showed the same immunohistochemistry pattern as the prior breast lesion. Pyloric stenosis has still been confirmed with an endoscopy, she has been alive with satisfactory oral food intake for >10 years.

Surface CD3-negative monomorphic epitheliotropic intestinal T-cell lymphoma.

Intestinal T/NK-cell lymphomas include enteropathy-associated T-cell lymphoma (EATL), monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), indolent T-cell lymphoproliferative disorders of the GI tract (ITCLPD), extranodal NK/T-cell lymphoma, nasal type (ENKTL), and intestinal T-cell lymphoma NOS (ITCL-NOS). Here we describe a case of surface CD3-negative MEITL. A 63-year-old Japanese female had a tumor located in the conglomerated ileum, which formed multiple mass lesions. The resected tissue showed a diffuse infiltration of monomorphic medium-sized lymphocytes with epitheliotropism. Flowcytometry using a fresh specimen of the tumor revealed positivity for CD7, CD8, CD38, and CD56, but not surface CD3. On immunohistochemistry, the tumor showed positivity for cytoplasmic CD3, CD8, CD56, TIA-1, Granzyme B, and perforin. EBER with in situ hybridization was negative. Moreover, H3K36me3, which is negative in MEITL with SETD2-mutation, was positive. This is an important case of MEITL due to its oncogenesis.

[Preoperative Imatinib Therapy Followed by Laparoscopic Local Gastrectomy for a Giant Gastric Gastrointestinal Stromal Tumor-A Case Report].

A 55-year-old man complained of abdominal distention. Gastroscopy showed a submucosal tumor in the upper-third portion of the stomach, with a biopsy diagnosis of gastrointestinal stromal tumor(GIST). Because abdominal contrast- enhanced CT findings suspected the invasion of the tumor into the pancreatic tail, preoperative imatinib therapy was performed. After 2 weeks of treatment, the tumor had shrunk to 44% of its starting volume. Six months later, CT findings suggestive of the tumor invasion had disappeared. Therefore, the laparoscopic local resection of the stomach was performed. The postoperative course was uneventful. A pathological diagnosis was c-kit-positive GIST, with less than 5/50 HPF of mitotic counts. Imatinib was restarted 2 weeks after the operation. The patient is alive 8 months after the operation, with no obvious recurrence. Preoperative imatinib therapy can be a useful option for large GIST tumors.

Donor quality of life in living-donor lobar lung transplantation.

BACKGROUND: Living-donor lobar lung transplantation has been established as a life-saving option for end-stage pulmonary diseases. However, factors associated with quality of life (QOL) of living lung donors have not been fully investigated. METHODS: A cross-sectional study was performed at Okayama University using the version 2 questionnaire of the 36-item Short Form (SF-36) Health Survey. Linear regression analysis was used to estimate the relationship of donor factors and recipient outcomes using the SF-36 component summary scores. RESULTS: Of 65 donors, 42 (65%) agreed to participate in this study; the mean age was 42 ± 1 (range 25 to 59) years. Mean time from the operation to questionnaire was 39 ± 4 (range 1 to 78) months. Donor-recipient relationships were as follows: sibling (18 cases); spouse (9 cases); parent (11 cases); and child (4 cases). Thirty-four of 42 donors were paired with those who donated their organ to the same recipient. Both physical and mental health scores in donors were higher than those in the general Japanese population. Lower mental health scores were seen in those who donated to their child or parent. There was a significant correlation in mental health scores between the paired donors. In the univariate analysis, donor age (r = -0.35, p = 0.02), donor-recipient relationship (r = 0.38, p = 0.01) and recipient death (r = -0.42, p = 0.006) were factors significantly associated with donor mental health scores. CONCLUSIONS: The average QOL in the living lung donors was better than that of the general population. However, a fatal outcome in the recipient significantly impacted donor mental health QOL. Ensuring that donor candidates consider both the risks/benefits of donation, and the potential recipient outcomes may be critical in the informed consent process.
