This study investigated the potential of DYRK2, a dual-specificity tyrosine-(Y)-phosphorylation-regulated kinase gene, to predict disease-free survival for patients with early stage breast cancer. Two hundred and seventy-four patients with breast cancer underwent surgery from January 2000 to December 2009. All patients were in stage I or II. Immunohistochemical (IHC) analysis was used to determine the expression of DYRK2, which was examined for its association with clinicopathological factors or prognosis. A total of 85 of 274 cases (31%) were DYRK2 positive. No correlation was found between DYRK2 expression by IHC and clinicopathological factors such as tumor size, histological grade, hormone receptor status, and HER2 status; however, lymph node involvement was closely associated with DYRK2 expression. Ten-year disease-free survival in the DYRK2-positive group without node metastasis (95.9%) was significantly better than that in the DYRK2-negative group (87.3%, p = 0.015). These data show that DYRK2 expression is associated with lymph node involvement and is a possible predictive factor of breast cancer recurrence.

RFA therefore could be an effective alternative to partial mastectomy for early breast cancer. Further research will be necessary to establish the standardization of the indications, as well as the optimal techniques and post treatment evaluation modalities.

<b><i>Background:</i></b> There is no study on the predictive factors of recurrent haemoptysis after bronchial artery embolization (BAE) with the long-term outcomes in patients with bronchiectasis (BE). <b><i>Objectives:</i></b> To evaluate the long-term outcomes of BAE in BE patients without accompanying refractory active infection of mycobacteriosis and aspergillosis with analysis for the predictive factors of recurrent haemoptysis. <b><i>Methods:</i></b> Data of 106 patients with BE who underwent BAE using coils between January 2011 and December 2018 were retrospectively reviewed. The cumulative haemoptysis control rate was estimated using Kaplan-Meier methods with log-rank tests to analyze differences in recurrence-free rate between groups based on technical success and failure, bacterial colonization status, number of BE lesions, and vessels embolized to bronchial arteries (BAs) or BAs + non-bronchial systemic arteries (NBSAs). <b><i>Results:</i></b> Bacterial colonization was detected in approximately 60% of patients. Computed tomography showed bronchiectatic lesions with 2.9 ± 1.4 lobes. In the first series of BAE, embolization was performed in the BAs alone and BAs + NBSAs in 65.1 and 34.9% of patients, respectively, with 2.4 ± 1.4 embolized vessels in total. The median follow-up period was 1,000 (7–2,790) days. The cumulative haemoptysis control rates were 91.3, 84.2, 81.5, and 78.9% at 1, 2, 3, and 5 years, respectively. The haemoptysis control rates were higher in the technical success group than in the technical failure group (<i>p</i> = 0.029). <b><i>Conclusions:</i></b> High haemoptysis control rates for long-term periods were obtained by embolization for all visualized abnormal arteries, regardless of the colonization status, number of bronchiectatic lobes, and target vessels, irrespective of NBSAs.

We report a gastrointestinal autonomic nerve tumor of the stomach with a giant abscess. The patient had fever and pain and was found to have anemia and an abdominal mass. X-ray and endoscopic examination showed a gastric submucosal tumor with a fistula to the gastric lumen. Partial gastrectomy was performed and no metastasis was found. On gross examination, the excised tumor was seen to be a submucosal solid tumor with a giant abscess. Alpha streptococci and anaerobic gram-negative rods were cultured from the pus of the abscess. The tumor resembled a gastric myogenic tumor composed of spindle cells, partly showing storiform and epithelioids. Tumor cells showed positive staining for vimentin and neuron-specific enolase but were negative for desmin, alpha-smooth muscle actin, and S-100 protein. Ultrastructural examination showed remarkable interdigitation of cytoplasmic processes with neurosecretory granules between the tumor cells. This lesion was similar to previously described gastrointestinal autonomic nerve tumors. Gastrointestinal autonomic nerve tumors are a rare, distinct subtype of gastrointestinal stromal tumors; although several cases of focally necrotic tumors have been reported, there has been only one report of the tumor with an abscess, as in our case.
