Several genes that encode PR (PRDI-BF1 and RIZ) domain proteins (PRDM) have been linked to human cancers. To explore the role of the PR domain family genes in breast carcinogenesis, we examined the ...expression profiles of 16 members of the PRDM gene family in a panel of breast cancer cell lines and primary breast cancer specimens using semiquantitative real-time PCR. We found that PRDM14 mRNA is overexpressed in about two thirds of breast cancers; moreover, immunohistochemical analysis showed that expression of PRDM14 protein is also up-regulated. Analysis of the gene copy number revealed that PRDM14 is a target of gene amplification on chromosome 8q13, which is a region where gene amplification has frequently been detected in various human tumors. Introduction of PRDM14 into cancer cells enhanced cell growth and reduced their sensitivity to chemotherapeutic drugs. Conversely, knockdown of PRDM14 by siRNA induced apoptosis in breast cancer cells and increased their sensitivity to chemotherapeutic drugs, suggesting that up-regulated expression of PRDM14 may play an important role in the proliferation of breast cancer cells. That little or no expression of PRDM14 is seen in noncancerous tissues suggests that PRDM14 could be an ideal therapeutic target for the treatment of breast cancer.
We report that the reactivity of a novel monoclonal antibody LpMab-23 for human cancer-type podoplanin (PDPN) is a predictor for a poor prognosis of tongue cancer.
The association between ...LpMab-23-recognizing cancer-type PDPN expression and clinical/pathological features were analyzed on 60 patients with stage I and II tongue cancer treated with transoral resection of the primary tumor.
In the mode of invasion, the LpMab-23-dull/negative cases were significantly larger in cases with low-grade malignancies and without late cervical lymph node metastasis, than in cases with high-grade malignancies and the metastasis. In the high-grade malignant cases, LpMab-23-positive cases were significantly larger than LpMab-23-dull/negative cases. The Kaplan-Meier curves of the five-year metastasis-free survival rate (MFS) were significantly lower in the LpMab-23 positive patients than in LpMab-23 dull/negative patients. The LpMab-23-dull/negative cases showed the highest MFS in all of the clinical/pathological features and particularly, the MFS of the LpMab-23 positive cases decreased to less than 60% in the first year. In the Cox proportional hazard regression models a comparison of the numbers of LpMab-23 dull/negative with positive cases showed the highest hazard ratio with statistical significance in all of the clinical/pathological features.
LpMab-23 positive cases may be considered to present a useful predictor of poor prognosis for early stage tongue cancer.
Histiocytic sarcoma in advanced clinical stages is typically an aggressive neoplasm, with poor response to conventional chemotherapy. An 18-year-old male with refractory histiocytic sarcoma that had ...transformed from Rosai–Dorfman disease was admitted to our hospital. A pathogenic variant of MAP2K1 was detected by next-generation sequencing of tumor specimens. Affected regions showed excellent responses to the MEK inhibitor trametinib. It has been reported that RAS/MEK/ERK pathway is activated in many cases of histiocytic sarcoma. MEK inhibition may represent a useful treatment option in histiocytic sarcoma.
Objective:
To clarify the morphological characteristics of hemifacial microsomia (HFM) by quantitative analysis of cephalometric radiographs.
Design:
Retrospective study of imaging data.
Setting:
...Imaging data were obtained from the records of Sapporo Medical University Hospital.
Patients:
A total of 183 patients with HFM.
Main Outcome Measures:
We used linear and angular measurements and analyzed the middle face and lower face.
Results:
The ratios of the affected side to the unaffected (A/U) side of the lateral distance of the mandibular condyle, the mandibular ramus height, and the length of the body of the mandible in the HFM group were significantly lower than in the control group. The inclination of the body of the mandible was significantly larger in the side with HFM than in the unaffected side, and the extent of the mandibular ramus was significantly lower than in the unaffected side. The A/U ratios of the extent of the angle of the mandible and the inclination of the body of the mandible in the HFM group were larger than in the control group. Moreover, the length and the inclination of the body of the mandible had significant correlations with the distance of the shift of the menton.
Conclusions:
It is suggested that improving the hypoplasia of the length of the body of the mandible and the extent of the angle of the mandible on the affected side will lead to more effective treatment of jaw deformity in patients with HFM.
We have previously reported that the low rate of osteoporosis patients treated with anti-osteoporotic drugs following surgical treatment for the first fragility fractures by orthopaedic surgeons ...during 3 years from 2000 to 2003 was only 13.1%. Ten years have now passed our previous study, and we hypothesized that the rate of appropriate pharmacologic treatment for the prevention of secondary fractures has improved.
We studied 730 osteoporosis patients (102 men and 628 women; average age of 78 years, range 33-102 years) who underwent surgical treatment for fragility fractures, during 3-year period from 2010 to 2012. The 730 cases consisted of 489 hip fractures and 241 distal radius fractures. All patients were admitted and underwent surgical intervention in hospitals. Variables were examined to ascertain whether pharmaceutical treatment was performed after discharge. Based on these data, we compared results for patients in the present study with those from our previous study.
The rate of treatment with anti-osteoporosis medication in the present (16.2%) was slightly but significantly improved from that in our previous study (13.1%). The rate of pharmaceutical treatment following hip fractures increased significantly, while that following distal radius fractures showed no significant change. Regarding the categories of anti-osteoporotic drugs prescribed to the patients, the rate of treatment with bisphosphonate as a higher evidenced drug for the prevention of fractures in the present study was significantly higher than that in our previous study.
We demonstrated that the rate of pharmacologic treatment by orthopaedic surgeons and the rate of more effective anti-osteoporotic drugs prescribed to the patients following surgical intervention for the first fragility fracture in the present study were improved in comparison with those of 10 years ago.
Aim
Cervical intra‐epithelial neoplasia (CIN) is the precancerous stage of cervical cancer. Standard treatment for high‐grade CIN is conization of the cervix. The risk of preterm birth following ...conization has been discussed recently. In contrast, laser vaporization is believed not to affect perinatal outcome, but the long‐term effectiveness of each surgical procedure is still unclear. The aim of this prospective unmatched‐cohort study was therefore to compare virological and cytological clearance and recurrence risk between conization and vaporization for CIN3.
Methods
Subject consisted of CIN3 patients treated at the present hospital between 2007 to 2011 and followed up until December 2014. One hundred and one patients were treated with laser conization, and 137 with vaporization. The surgical procedure was selected on the basis of colposcopy, pathological grade and patient's hope for pregnancy.
Results
There were no significant differences in cure rate, human papilloma virus (HPV) clearance rate or recurrence rates between the conization and vaporization groups. Risk ratio of recurrence for each surgical procedure adjusted for age and HPV persistence status were analyzed on Cox proportional hazards modeling. Recurrence risk ratio for patients treated by vaporization was 6.21 (95%CI: 0.65–59.19; P = 0.111) compared with conization and there were no significant differences. No adverse pregnancy outcome was observed in the vaporization group compared with conization.
Conclusions
Laser vaporization is useful for young patients with CIN3 who hope for pregnancy in the future.
Background
Single‐dose i.v. fosaprepitant has been approved as an alternative to 3 day oral aprepitant, a neurokinin‐1 receptor antagonist, and improves prevention of chemotherapy‐induced nausea and ...vomiting (CINV). Because fosaprepitant has shown similar efficacy to aprepitant in adult patients only, this study compared the efficacy and safety of aprepitant and fosaprepitant in pediatric patients.
Methods
Children younger than 18 years who received aprepitant or fosaprepitant to manage CINV between January 2015 and March 2018 at the National Cancer Center Hospital (Tokyo) were recruited to this study. The primary endpoint was complete response (CR; no vomiting/rescue medication) between 0 and 120 h after the start of chemotherapy. Secondary endpoints were safety based on the frequency of severe adverse events, and evaluation of patient characteristics as risk factors (effect of age and sex).
Results
A total of 125 chemotherapy cycles were evaluated. In the aprepitant group, CR was observed in 36 of 80 treatment cycles (45.0%), whereas in the fosaprepitant group, it was observed in 19 of 45 cycles (42.2%; P = 0.852). No treatment‐related severe adverse events were observed in either group. The number of non‐CR was greater than that of CR in patients aged 6–14 years. The difference in CR rate between male and female patients was not statistically significant (47.1% vs 40.0%, respectively; P = 0.471).
Conclusions
Aprepitant and fosaprepitant were safely used and may be equally useful for pediatric patients receiving highly emetogenic chemotherapy. CR rate may be associated with patient age.
Abstract
Background and study aims
Although new image-enhanced endoscopy (IEE) technologies such as blue laser imaging (BLI), BLI-bright, and linked color imaging (LCI) have been developed, their ...utility for the detection of sessile serrated adenoma/polyps (SSA/Ps) is still unclear. This study aimed to evaluate the utility of BLI, BLI-bright, and LCI for SSA/P detection in still image examinations and in a prospective randomized controlled trial (RCT).
Patients and methods
A group of 6 expert and non-expert endoscopists read 200 endoscopic still images containing SSA/P lesions using white light image (WLI), BLI, BLI-bright, and LCI. Color differences were calculated using the color space method. A prospective RCT of tandem colonoscopy with WLI and LCI was performed. Patients with SSA/P and those with a history of SSA/P that had been endoscopically removed were enrolled and randomly allocated to WLI-LCI or LCI-WLI groups. Additional endoscopic detection rates for SSA/P were compared between the 2 groups.
Results
LCI showed the highest SSA/P detection rate among the 4 modes for both expert and non-expert endoscopists. The detection rate with LCI for the 6 expert endoscopists (mean 98.3 ± standard deviation 2.0 %) was significantly higher than that with WLI (86.7 ± 6.0 %,
P
< 0.01). Likewise, the detection rate with LCI for the 6 non-expert endoscopists (92.3 ± 2.9 %) was significantly higher than that with WLI (72.7 ± 11.5 %,
P
< 0.01). The color difference of SSA/P with LCI was the highest among the 4 modes, and was significantly higher than with WLI (median 15.9, (interquartile range 13.7 – 20.6) vs. 10.2, (7.6 – 14.2);
P
< 0.0001). In the RCT, a total of 44 patients (WLI-LCI 22 vs. LCI-WLI 22) underwent colonoscopy. The additional detection rate for SSA/P in the second inspection in the WLI-LCI group (21.6 %, 8/37) was significantly higher than in the LCI-WLI group (3.2 %, 1/31;
P
= 0.02). The small, flat, non-mucus and isochromatic SSA/Ps in the transverse colon were detected more frequently in the second inspection with LCI.
Conclusions
LCI was the most sensitive mode for SSA/P detection among WLI, BLI, BLI-bright, and LCI in the still image examinations. Our RCT strongly suggests that LCI is superior to conventional WLI for SSA/P detection during colonoscopy. UMIN000017599.
We examined associations between nutritional and other lifestyle factors and the prevalence of prostate cancer in a case-control study of Japanese men. Two hundred patients and 200 age-matched ...controls (+/-5 y) were selected from 3 geographic areas of Japan. BMI, physical activity, occupation, family history of prostate cancer, and medical history were not associated with prostate cancer risk. Isoflavones and their aglycones (genistein and daidzein) were significantly associated with decreased risk. The odds ratio for the highest category (> or = 89.9 mg/d) compared with the lowest category (<30.5 mg/d) of isoflavone intake was 0.42 (95% CI = 0.24-0.72) and the linear trend was significant (P < 0.01). PUFA, (n-6) fatty acids, and magnesium were significantly associated with decreased risk but not after adjustment for isoflavone intake. Isoflavone intake was correlated with the intake of PUFA (r = 0.68, P < 0.001), (n-6) fatty acids (r = 0.69, P < 0.001), and magnesium (r = 0.56, P < 0.001), because soy products contain high levels of these nutrients. On the other hand, isoflavone significantly decreased the risk of prostate cancer regardless of adjustment by PUFA, (n-6) fatty acids or magnesium. In conclusion, our findings indicate that isoflavones might be an effective dietary protective factor against prostate cancer in Japanese men.
