This article presents the interim results of treatment of patients with colorectal cancer, who were enrolled from 2016 till 2019 (n=60) with the use of maintenance metronomic chemotherapy. Metronomic regimen consisted of oral capecitabine 500 mg 3 times a day and oral cyclophosphane 50 mg daily. The control arm consisted of mCRC patients who received the same induction chemotherapy without maintenance from 2011 till 2015 (n=70). Median follow-up time was 18.5 months. Median progression-free survival (PFS) was 9.0 and 7.4 months in the maintenance and control arms respectively. Median overall survival (OS), counted from the beginning of induction chemotherapy, is currently 22.9 months in the maintenance arm, and 14.7 months in control. High expression levels of genes, encoding enzymes TS (thymidylate synthetase), DPD (dihydropyrimidine dehydrogenase) and receptor VEGFR1, low expression level of gene TP (thymidylate phosphorylase), as well as low levels of tumor markers CEA and СА 19-9 are the prognostic factors of sensitivity to metronomic chemotherapy given to colorectal cancer patients. Based on these data, we identified a group of patients who are recommended to use this method of treatment.","PeriodicalId":89904,"journal":{"name":"Cancer and clinical oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45912922","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}

As the age increases, the risk for this cancer also increases, so the only way to improve and hope for life in these patients is early diagnosis of the disease. So far, numerous molecular studies have been carried out on microRNAs in colorectal cancer. In addition, since some of them can be identified as cancer biomarkers. Therefore, in this study we have investigated the expression level of Mir-30d and Mir-181a as cancer biomarkers. \u0000 \u0000Method: The changes of Mir-30d and Mir-181a expression levels in 60 colorectal tumor tissues and 60 adjacent tumor tissues, after RNA extraction and cDNA synthesis were surveyed using the Real Time-PCR method. \u0000 \u0000Results: The results have reported a considerable reduction in the expression level of Mir-30d in tumor tissues, as well as a significant increase in the expression level of Mir-181a tumor expression in tumor tissues (P<0.05). In addition, the correlation between Mir-30d and Mir181a showed that there was a significant difference between the level of expression of mir-30d with age and TNM stage of CRC (P<0.05), whilst these correlations were not observed for Mir-181a (P>0.05).","PeriodicalId":89904,"journal":{"name":"Cancer and clinical oncology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43208833","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}

Therefore, the purpose of this report was to evaluate objective response (OR), progression-free survival (PFS), overall survival (OS), and the incidence of adverse events (AEs) in rGBM patients, age 19-70 years, who were treated with antineoplaston AS2-1 (Astugenal) plus targeted therapy. A retrospective analysis was performed. Tumor response was assessed by gadolinium-enhanced magnetic resonance imaging (MRI). Twenty-nine adult rGBM patients were treated between 9/11/2015 and 06/23/2018. Seven had no prior treatment with bevacizumab elsewhere, had radiologic evidence of rGBM, and had MRI assessment of tumor response. The median treatment time was 101 days (range: 55-208 days). OR was seen in six patients (85.7%) with complete disappearance of gadolinium enhancement in four patients (57.1%) and a 50% or greater reduction in gadolinium enhancement in two patients (28.6%). Progressive disease was seen in one patient (14.3%). The median time to first response was 29 days (range: 22-96 days) while the median duration of response was 141 days (range 55-739+ days). Six- and 12-month PFS was 57% and 19%, respectively while 6- and 12-month OS at was 86% and 54%, respectively. Treatment was well-tolerated with no patients experiencing grade 3 or 4 antineoplaston-related toxicity. Regarding response to treatment and toxicity, AS2-1 plus targeted therapy compares favorably with other reported rGBM therapies. Duration of response was shortened by the ill-advised decision of some patients to discontinue treatment after a tumor response was achieved. \u0000 \u0000 ","PeriodicalId":89904,"journal":{"name":"Cancer and clinical oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44718362","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}

Two competing techniques in doing so exist and involve the traditional placement of surgical clips in the surgical tumor bed or the newer technique of placing a Biozorb marker in the tumor bed. Our goal was to perform a cost-utility assessment to see which tumor bed marking approach is more cost-effective. Based on device list prices and clinical outcomes from a comprehensive literature review, we assessed if an approach either dominated or had an incremental cost-utility ratio of less than $50,000/QALY since either would signify cost-effectiveness. \u0000 \u0000Results: \u0000 \u0000From a cost comparison, the Biozorb marker ($1250) was far costlier than the clip applier device ($50). Our PRISMA search (Figure 1) reviewed 133 articles for clip placement and 42 articles for Biozorb placement in oncoplastic surgery with 2 clip placement articles and 3 Biozorb articles meeting criteria. The available data for either marking technique suggests reasonable tumor bed identification for adjuvant radiation treatment without clear clinical advantages supporting one technique over the other. Overall clinical equivalence in the setting of a clear cost advantage suggests dominant cost-effectiveness in favor of clips. \u0000 \u0000Conclusion: \u0000 \u0000Using surgical clips to identify the tumor bed in oncoplastic surgery is dominant and more cost-effective over the Biozorb technique as clips are relatively inexpensive while both techniques reasonably identify the tumor bed.","PeriodicalId":89904,"journal":{"name":"Cancer and clinical oncology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43229401","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}

The value of the receptor status prior to definitive surgery with either breast conservation or mastectomy for patients with ductal carcinoma in situ (DCIS) and no invasive component is less clear. \u0000 \u0000Methods: We identified through the tumor registry 344 patients with breast cancer diagnosed from 2014 through 2015. Two hundred seventy-seven patients had invasive cancer at diagnosis. \u0000 \u0000Results: Of the remaining 67 patients with DCIS or atypical hyperplasia alone on core biopsy, 15 (22%) patients were found to have invasive cancer at the time of definitive surgery. \u0000 \u0000Forty-six patients without an invasive component had definitive surgery at the study institution, of which three had a component of higher grade DCIS than on the core biopsy. Fourteen patients (30%) underwent a mastectomy. \u0000 \u0000Conclusion: A significant proportion (29%) of patients with DCIS alone on core biopsy had either an invasive component at the time of definitive surgery or a higher grade DCIS component.
