It has been shown that they use the Internet to actively search for health-related information, but it has not yet been determined what kinds of information are sought. There is a gap in our present understanding of the information needs of the Filipino population in relation to cancer. The study assessed the cancer-related information needs of Filipinos using Internet search data from March 2015 to May 2019. Methods: A retrospective longitudinal study was done using Google AdWords Keyword Planner to identify search terms related to cancer from Internet users from the Philippines from June 2015 to May 2019. The identified search terms were assessed descriptively using Microsoft Excel version 16.26. The search terms were qualitatively categorized and described. Results: A total of 806 cancer-related search terms were identified, with 13,632,890 Google web searches, during the period under review. The top ten search terms with the highest monthly search volume in the Philippines (n=4,741,600, 34.78%) were “cancer,” “breast cancer,” “cervical cancer,” “prostate cancer,” “colon cancer,” “breast cancer symptoms,” “lung cancer,” “lung cancer symptoms,” “colon cancer symptoms,” and “lungs.” In this time period, Filipinos sought information on cancer-related signs and symptoms (n=3,307,640, 24.26%) and cancer treatment (n=604,070, 4.43%). Filipinos also searched for alternative, herbal, and natural cancer treatments, but the search volume accounted for a low percentage of the total searches (n=8,710, 0.06%). Searches for the search term, “cancer,” were highest on January to February, a trend observed from January 2016 to 2019. Conclusions: Our study provides insight into the cancer-related information needs of the Filipino population. This information may inform the development of targeted, cost-effective awareness campaigns through the Internet, which may be more effective if launched at the beginning of each year.","PeriodicalId":15862,"journal":{"name":"Journal of global oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42454233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we evaluatedthe expression and clinical significance of FOXO1 in EOC. Methods: Immunohistochemical analyses of FOXO1 and PAX3 in 212 in EOCs, 57 borderline ovarian tumors and 153 benign epithelial ovarian tumors and 79 nonadjacent normal epithelial tissues were performed using tissue microarray analysis. The data were compared with clinicopathological variables including the survival of EOC patients. Also, the effect of FOXO1 on cell growth were assessed in EOC cell lines. Results: The expressions of FOXO1 and PAX3 protein were significantly higher in EOC tissues than in nonadjacent normal epithelial tissues, benign tissues and borderline tumors respectively (all p< 0.001). Overexpression of FOXO1 was significantly associated with poor grade ( p = 0.004). FOXO1 expression showed trend of positive correlation with that of PAX3 in EOC tissues ( Spearman’s rho0.118, p= 0.149). Multivariate survival analysis revealed that the high expression of FOXO1 (hazard ratio = 2.74 [95% CI, 1.22–13.10], p = 0.001) could be an independent prognostic factor for overall survival. Most importantly, high expression of both FOXO1 and PAX3 showed high hazard ratio (hazard ratio = 5.53 [95% CI, 2.47–12.40], p< 0.001) for overall survival. In vitro result revealed that knockdown of FOXO1 was associated decreased cell viability and migration. Conclusions: This study reveals that high expression of FOXO1/PAX3 is an indicator of poor prognosis in EOC. Our results not only suggest the promising potential of FOXO1 and PAX3 as a prognostic and survival marker, but also warrant further studies on a possible link between the biological function of FOXO1 and PAX3 of EOC.","PeriodicalId":15862,"journal":{"name":"Journal of global oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45656032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: The study was approved by the ethics committee of two tertiary medical centers in China. From Jan 2010 to Dec 2016, 260 consecutive patients with intermediate rHCC after initial hepatectomy who underwent combination treatment or TACE were enrolled. Overall survival (OS) and progression-free survival (PFS) were compared between these two treatments according to MVI status. Results: The 1-, 3-, 5-year OS (77.1% vs. 62.0%, 49.3% vs. 35.2%, 38.9% vs. 20.5%, P = 0.011) and PFS (74.2% vs. 56.5%, 37.5% vs. 18.7%, 37.5% vs. 18.7%, P = 0.003) rates were significantly higher in the combination group than those in the TACE group for intermediate rHCC. For MVI-positive patients, the median OS (17.2 months vs. 12.1 months, P = 0.024) and PFS (17.0 months vs. 11.0 months, P = 0.022) after combination treatment (n = 55) were significantly longer than those after TACE alone (n = 72). For MVI-negative patients, the median OS (42.7 months vs. 32.6 months, P = 0.247) and PFS (24.6 months vs. 17.2 months, P = 0.113) were comparable between combination therapy (n = 73) and TACE alone (n = 60).

Methods: We reviewed deaths of 52 metastatic cancer patients treated with multidimensional integrative medicine (MIM) approach. Patients received standard oncologic treatment plus a MIM predefined program of emotional, cognitive and social support. The method included empathy improvement, changes on physician attitude and office environment, modulation of staff behavior supporting patient’s needs and rights, promotion of belongingness, increasing on patient’s protagonism using multimedia interactive narrative and shared decision-making. Patients were categorised according to the tumor site, pathologic, molecular and IHC characteristics, clinical stage and treatment. Observed survival was defined as the time elapsed between the detection of first metastasis and death. The observed survival for each patient was compared with the median expected survival previously reported on prospective randomised trials which had accrued patients with similar prognostic factors based on a best fit model. Treatment monthly cost for each patient was converted in American dollars (USD) on a daily exchange basis. Cost of the treatment periods were compared with those analysed in four large USA commercial managed care plans. Results: Treatment of metastatic cancer patients using MIM showed a 44% increase in median survival and a 48% decrease in cost. The estimated ICER/QALY was of 32304 USD, which represented 2.0 of Brazilian PPP.

However, detection of ultra-low mutation allelic frequency (MAF) of ctDNA at early stages of cancer is infeasible by conventional next generation sequencing (NGS). Using duplex sequencing with unique molecular identifiers (UMIs) and custom-designed probes, we tested the hypothesis that ctDNA duplex sequencing with UMIs was able to detect ultra-low MAF of ctDNA in patients with early-stage cancers. Methods: A 128-gene panel that contains probes targeted to clinical relevant genome variations in cancers of the lung, stomach, and esophagus was designed and validated with reference DNA and controls using ctDNA duplex sequencing with UMIs. A data analysis pipeline was implemented withimproved algorithms for variant calling, blood tumor mutational burden (bTMB) calculation, and supervised machine learning for tissue-of-origin primary cancer identification. Results: We designed and validated a ctDNA duplex sequencing with UMIs assay that enables simultaneous detection of 128 clinical relevant geneswith SNPs, indels, amplifications, and fusions in a single blood test. Compared to conventional ctDNA NGS, our assay achieved high sensitivity (over 82%) and specificity (over 96%) with LOD at 0.1% MAF for stage I lung, gastric and esophageal cancers with the sequencing depth at 30,000x from a cohort of 136 clinical samples. Results also showed significant concordance of MAF and TMB between DNA from tumor tissues and plasma ctDNA. Our deep learning predictive model with novel algorithms and features for tumor tissue-of-origin classification achieved an overall 85% accuracy. Conclusions: In this study, a novel ultrasensitive assay was designed and validated for accurate detection of MAF at 0.1% from plasma ctDNA of multiple tumors, and accurate classification on tissue-of-origin for major primary cancers using supervised deep learning.

We aimed to determine the efficacy and safety of AG compared with GEM for resected PDAC. Methods: We retrospectively reviewed resectable PDAC patients (pts) who received AG or GEM as adjuvant chemotherapy from January 2013 to December 2016 at the Chinese PLA General Hospital, Bei Jing, China. Pts received nab-paclitaxel (125mg/m2) followed by GEM (1,000 mg/m2) on days 1, 8 every 3 weeks or GEM (1,000 mg/m2) alone on days 1, 8 every 3 weeks for 6 cycles unless disease progression or there was unacceptable level of adverse events.

This study aimed to clarify the predictors of ILNM and clinical significance of treatment for ILNM. Methods: Consecutive patients with rectal adenocarcinoma invading the anal canal who underwent curative surgery between 2003 and 2019 at a single institution were retrospectively reviewed. The pathological nodal involvement in mesorectal, lateral pelvic or inguinal lymph nodes (ILN) at the time of rectal surgery and of later onset were collectively defined as final nodal metastasis (f-LNM) in this study. Factors associated with f-LNM were analyzed. Moreover, the ‘modified therapeutic value index’ defined by the 5-year overall survival rate of patients treated against f-LNM multiplied by their frequency was calculated for each lymph node area. Results: A total of 145 patients were enrolled, among whom16 patients developed ILNM. For predicting f-ILNM, the cutoff 8.5 mm of ILN diameter gave area under the curve of 0.889. Dentate line involvement and ILN larger than a simplified cutoff of 8 mm were independently associated with the development of ILNM (odds ratio: 33.4 and 11.9, respectively).

The median follow-up time was 5.43 months, patients with mobile application had longer median OS than patients with routine follow up (4 months vs 2.9 months, p-value = 0.5). Conclusions: Lung Cancer Care application based on self-reported symptoms is a novel electronic device for real-time patient care monitoring. Our study results showed trend towards improved quality of life from using this novel mobile application. However, there was small samples for pilot testing, the relatively large sampling errors may reduce the statistical power needed to validate this tool.","PeriodicalId":15862,"journal":{"name":"Journal of global oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41599529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
