<P><B>BACKGROUND</B></P><P>Genomic profiling of tumors has contributed to the understanding of colorectal cancer (CRC), facilitating diagnosis, prognosis and selection of treatments, including targeted regimens. A report suggested that a 19-gene-based risk classifier (TCA19) was a prognostic tool for patients with stage III CRC. The survival outcomes in patients with stage IV CRC are still poor and appropriate selection of targeted therapies and immunotherapies is challenging.</P><P><B>AIM</B></P><P>To assess clinical implication of TCA19 in patients with stage IV CRC, and to identify TCA19 with involvement in immune-oncology.</P><P><B>METHODS</B></P><P>A retrospective review of the medical records of 60 patients with stage IV CRC was conducted, assessing clinicopathological variables and progression-free survival (PFS). TCA19 gene expression was determined by quantitative polymerase chain reaction (qPCR) in matched normal and tumor tissues taken from the study cohort. Expression of potential immune-oncology regulatory proteins and targets was examined by immunohistochemistry (IHC), western blot, immunofluorescence staining in tissues from a validation cohort of 10 patients, and in CRC cell lines co-cultured with monocyte <I>in vitro</I>.</P><P><B>RESULTS</B></P><P>In the patients with TCA19 score higher than the median, the PFS rates of eight patients who received the targeted regimens were significantly higher than the PFS rates of four patients who received 5-fluorouracil-based regimen (<I>P</I> = 0.041). In multivariate analysis, expression of signaling lymphocytic activation molecule family, member 7 (SLAMF7) and triggering receptor expressed on myeloid cells 1 (TREM1) was associated with PFS in the 60-patient cohort. After checking another 10 validate set, the expression of the IHC, the level of real-time qPCR, and the level of western blot were lower for SLAMF7 and higher for TREM7 in primary and metastatic tumors than in normal tissues. In CRC cells expressing SLAMF7 that were co-cultured with a monocytic cell line, levels of CD 68 and CD 73 were significantly lower at day 5 of co-culture than at day 0.</P><P><B>CONCLUSION</B></P><P>The TCA19 score might be prognostic for target-regimen-specific PFS in stage IV CRC.

Park, Jong-Lyul,Kim, Seon-Kyu,Kim, Jeong-Hwan,Yun, Seok Joong,Kim, Wun-Jae,Kim, Won Tae,Jeong, Pildu,Kang, Ho Won,Kim, Seon-Young Korea Genome Organization 2018 Genomics & informatics Vol.16 No.3

Because castration-resistant prostate cancer (CRPC) does not respond to androgen deprivation therapy and has a very poor prognosis, it is critical to identify a prognostic indicator for predicting high-risk patients who will develop CRPC. Here, we report a dataset of whole genomes from four pairs of primary prostate cancer (PC) and CRPC samples. The analysis of the paired PC and CRPC samples in the whole-genome data showed that the average number of somatic mutations per patients was 7,927 in CRPC tissues compared with primary PC tissues (range, 1,691 to 21,705). Our whole-genome sequencing data of primary PC and CRPC may be useful for understanding the genomic changes and molecular mechanisms that occur during the progression from PC to CRPC.

Background/Aims : Defecation syncope is a subgroup of neurocardiogenic syncope which occurs during or immediately after defecation. The aim of this study was to evaluate the clinical characteristics of patients with defecation syncope and the usefulness of head-up tilt test (HUT) in diagnosing the defecation syncope. Methods: Forty-five patients who had a history of defecation syncope or presyncope were selected from 454 patients who underwent HUT from Oct, 1994 to Jan, 1998. Their clinical characteristics and HUT results were reviewed retrospectively. Twenty-one subjects with positive HUT were interviewed by telephone about the recurrence of symptoms after diagnosis. Results: Median frequency of defecation syncope or presyncope was 4 (range; 1-30) and 34 subjects (75.6%) out of 45 patients were females. Injury due to the events occurred in 9 subjects (20%). In 16 cases (35.6%), syncope or presyncope occurred under situations other than bowel activity. Majority of the patients (40 cases, 88.9%) had prodromal symptoms. The result of HUT was positive in 29 subjects (64.4%). Clinical characteristics of the patients showed no difference according to sex and results of HUT. Conclusions: Defecation syncope is a subgroup of neurocardiogenic syncope and the head-up tilt test can be a useful tool in diagnosing the defecation syncope or presyncope.

Background/Aims: The aim of this study was to investigate predictive factors for malignant transformation of colorectal adenomatous polyps in Korea. Methods: One thousand five hundred and eighty- nine sessions of colonoscopic polypectomy were performed from November 1994 to September 1998 for 1,375 patients with adenomatous polyps at Samsung Medical Center. We analyzed the 2,179 adenomatous polyps including 55 (2.5%) polyps with malignant transformation, retrospectively. Results: Six parameters showed significant differences in univariate (p$lt;0.01) and multivariate analysis. For each parameter, the proportions of malignant polyps were as follows: for number of polyps, 1.3% in cases of single polyp and 10.3% in cases of multiple polyps; for size, 1.4% of polyps less than 1 cm and 15.5% of polyps larger than 1 cm; for location, 4.6% of the polyps located in rectum or sigmoid colon and 1.1% of the polyps located in descending to ascending colon; for morphology, 0.9% in polyps of Yamada type I/II and 7.6% in polyps of Yamada type III/IV; for underlying histology, 1.4% in cases of tubular adenoma and 8.1% in cases of tubulovillous or villous adenoma; for degree of dysplasia, 1.2% in cases accompanied with low-grade dysplasia and 8.9% in cases accompanied with high-grade dysplasia. Conclusions: The malignant potential of colorectal adenomatous polyps in Korea is correlated with multiplicity, distal location, pedunculated shape as well as well-known factors like size, histologic type and degree of dysplasia.

중성자교정실내에서 D₂O 감속 252Cf중성자선원을 사용하여 계측기를 교정할 때는 그 계측기에 대한 교정실산란정보인자를 미리 결정하여야 한다. 이러한 교정실산란보정인자는 계측기의 종류, 교정거리, 교정실형태에 따라 다르게 결정된다. 본 연구에서는 한국원자력연구소에서 운영하는 2차 표준중성자교정실에서 한가지의 열형광선량계와 2가지의 구형검출기에 대한 교정실산란보정인자를 실험적으로 결정하였고 본소의 2차 표준중성자교정실조건에 의하여 이론적으로 예측한 값과 비교 예측한 비교하였다. 비교한 결과 실험하여 얻어진 상기의 3가지 계측기에 대한 교정실산란정보인자가 이론적으로 예측한 결과와 최대 약 10% 이내에서 일치하였다. Neutron room scattering corrections that should be made when neutron detectors are calibrated with a D₂O moderated 252Cf neutron source in the center of a calibration room are considered. Such room scattering corrections are dependent on specific neutron source type, detector type, calibration distance, and calibration room configuration. Room scattering corrections for the responses of a thermoluminescence dosimeter and two different types of spherical detectors to neutron source in the Radiation Calibration Laboratory (RCL) neutron calibration facility at the Korea Atomic Energy Research Institute(KAERl) were experimentally determined and are presented. The measured room scattering results are then compared with theoretical results calculated by predicting room scattering effects in terms of parameters related to the specific configuration. Agreement between measured and calculated scattering correction is generally about 10% for three kinds of detectors in the calibration facility.

ANSI N13.32에서는 선량계의 방향에 따른 반응도가 성능시험의 합격판정의 범주는 아니지만 이에 관한 연구를 요구하고 있다. 본 연구에서는 ANSI N13.32의 말단팬텀 즉, 손가락과 손목팬템내의 7㎎/㎠ 깊이에서 MCNP 코드를 사용하여 단일에너지를 가진 광자 및 ISO narrow X-선 빔에 대하여 선량당량환산인자와 방향의존성인자를 도출하였다. X-선 빔에 대하여는 이들 데이터를 B. Grosswent의 연구 결과와 비교하였다. 그 결과 선량당량환산인자는 낮은 에너지영역에서 최대 7%를 그리고 다른 에너지 영역에서는 2% 이내였을며, 방향의존성인자는 최대 3% 정도로 잘 일치하였다. 또한 60keV 이하의 낮은 에너지 영역에서 발생된 방향의존성인자는 손가락 팬텀의 경우에 주축을 따라 수평회전각이 증가할수록 감소하지만 그 에너지 영역 이상에서 90˚까지는 증가하고 있음을 알 수 있었다. The ANSI N13.32 recommends that a study of the angular response of a dosimeter be carried out once, although no pass/fail criterion is given for angular response. Gamma dose equivalent conversion and angular dependence factors were calculated by using MCNP code for the case of ANSI N13.32 extremity phantoms(finger and arm) at the depth of 7㎎/㎠. Those extremity dosimeters were assumed to be irradiated form both monoenergitic photons and ISO X-ray narrow beams. These calculated gamma dose equivalent conversion and angular dependence factors were compared to B. Grosswendt's result calculated by using X-ray beams. The result showed that the dose equivalent conversion factors of this study agreed well with that of B. Grosswendt for all energies within 2% except &% in the case of the low energies. In the case of angular dependence factors comparison, they agreed within 3%. It was shown that angular dependence factors of the finger phantom decreased as the horizontal angle of the phantom increased for the ISO X-ray beams less than 60keV. For the higher energy X-ray beams range they decreased slightly around 40 degree, but then increased from this energy to 90 degree.
