“…From our study, the treatment of PDLs was also in line with the current treatment trend, but interestingly, the proportion of PDLs treated by surgery was lower than that of the stomach (9.64%) and the small intestine (35.13%), among which it was significantly lower than that of the small intestine. e reason may be that the duodenal lesion is mostly found in the descending segment [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], which has a complex anatomical structure and a small possibility of local resection, unlike the small intestine which can be directly resected, so conservative treatment is more preferred. Once a larger operation is performed, it is bound to cause complications and affect the quality of life.…”

“…As primary duodenum lymphomas (PDLs) are exceedingly rare, the current researches about PDLs are based on anecdotal reports [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. In the present study, we retrospectively reviewed the clinical and pathological manifestations of lymphomas of duodenum lymphoma for cases based on the largest sample size so far to identify prognostic factors and to clarify the value of treatment modalities in the management of these malignancies.…”

Objective. Primary duodenum lymphoma (PDL) is extremely rare with limited data available in the literature. In this study, we sought to describe clinical features and identify factors affecting survival in patients with PDL using a large population cohort. Methods. The Surveillance, Epidemiology, and End Results (SEER) database was queried from 1998 to 2015. Results. A total of 1060 cases of PDLs were identified. Clinicopathological features as well as survival data of PDLs were analyzed and compared with 10573 primary gastric lymphomas (PGLs) and 3239 primary small intestinal lymphomas (PSILs) from the SEER database. PDL patients were younger in age (60.96 ± 15.205), and the proportion of stage I (53.21%) was higher in Ann Arbor staging. The proportion of PDLs treated by surgery (8.68%) is the lowest among PDLs, PGLs, and PSILs. The DSS of PDLs were significantly better than those of PGLs and PSILs, respectively (10-year survival rate: 21.24% vs. 20.40%, P=0.027; 10-year survival rate: 21.24% vs. 16.79%, P=0.001). Age, gender, Ann Arbor staging, and histological type were regarded as independent prognostic factor for the DSS by multivariate analysis (all P<0.05). Patients with <65 years, female, stage I, and FL were found to be significantly associated with good DSS. The treatment modality (surgery vs. conservative treatment) was not statistically related to DSS. The proportion of PDL patients who received surgical treatment gradually decreased from 15.60% in period 2 to 5.26% in period 4. Conclusions. The clinicopathologic features of duodenal lymphoma were significantly different from those of gastric lymphoma and small intestinal lymphoma. The prognosis of PDLs was significantly better than those of the other two groups, and there was no statistical survival benefit from surgery in PDLs.

“…For example, in a study of 307 cases of primary GI non-Hodgkin's lymphoma, 244 cases (80%) had gastric lymphoma and 63 cases (20%) intestinal lymphoma [ 14 ], whereas in another study of 150 GI lymphomas, 105 patients had gastric lymphoma, 27 patients had jejunoileal lymphoma, and only 1 patient had primary duodenal lymphoma [ 15 ]. The literature review of duodenal MALTomas identified only 17 cases reported before 2004 [ 16 ], and only moderately more cases have been reported since [ 11 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ].…”

Clinical data regarding mucosa-associated lymphoid tissue lymphoma (MALToma) solely involving the duodenum are sparse because of the relative rarity of the disease. A comprehensive literature review revealed only 17 cases reported until 2004, and only a moderate number of cases have been reported since. MALToma can be asymptomatic in its very early stages but frequently produces localized or nonspecific symptoms, including early satiety, abdominal pain, vomiting, and involuntary weight loss in later stages. While gastric MALToma is strongly associated with gastric Helicobactor pylori infection, duodenal MALToma is often unassociated with H. pylori infection. A 74-year-old female presented with only dysphagia (without symptoms referable to a duodenal lesion), without systemic ‘B’ symptoms, and with no evident duodenal lesions at esophagogastroduodenoscopy; however, she was diagnosed with duodenal MALToma by pathologic examination of random duodenal biopsies performed to exclude celiac disease. An important clinical feature of this case is that duodenal MALToma was diagnosed by pathologic analysis of duodenal biopsies despite (1) no endoscopically apparent duodenal lesions; (2) duodenal involvement without gastric involvement; (3) lack of symptoms attributable to duodenal MALToma, and (4) absence of evident H. pylori infection. This work shows that early duodenal MALToma can be difficult to diagnose because of absent symptoms, absence of gastric involvement, absence of endoscopic abnormalities, and absence of H. pylori infection; it may require random duodenal biopsies for diagnosis.

“…For instance, xray radiograph can be formed with simple integrating circuits such as CCDs and CMOS. [5,6] From that point of view, gaseous scintillation with GEMs has been studied in past works, in order to simplify the signal readout for imaging. [7][8][9][10] Scintillation light caused during electron avalanche process with scintillation gas (such as CF 4 ) can be easily detected with optical camera.…”

Abstract.A large size x-ray imaging gaseous detector, which has 280 × 280 mm 2 effective area has been successfully developed and x-ray imaging has been demonstrated. The imaging system consists of a chamber filled with Ne/CF 4 scintillating gas mixture, inside of which Glass GEM (G-GEM) is mounted for gas multiplication. In this system electrons are generated by the reaction between x-rays and the gas, and visible photons by excited Ne/CF 4 gas molecules during the gas electron multiplication process in the G-GEM holes. These photons are simply detected with CCD-camera and a radiograph is formed. Here, we report on the properties of large size scintillation G-GEM and the results of using it as a digital x-ray imager with a large sensitive area.
