Despite this, the incidence of new diagnoses is increasing every day, as well as an increase in the cure rate, which is due, among other reasons, to the intensification of cancer treatment. As a consequence, these patients end up needing intervention in intensive care units (ICU). When compared to other patients, the mortality rate of cancer patients was higher than the general mortality in the pediatric ICU. For this reason, it is important to identify prognostic factors that can guide the early admission of these patients to the ICU. This study evaluated several variables related to the cancer patient admitted to the ICU, correlating them with the clinical outcome. Some variables were identified that increased the risk of the patient presenting with death as outcome, namely the number of organic dysfunctions on admission, the use of cardiotoxic chemotherapy, the use of nephrotoxic medications and the number of interventions performed on the patient in the first hours in the ICU. It is hoped that with this article, teams that provide health care to pediatric cancer patients will be able to identify children and adolescents in need of ICU interventions earlier, thus increasing their survival rate.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79394561","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}

{"title":"The Contribution of Radiology Service Staffs in the Optimization of TAP-CT Doses for Cancer Patients: A Comparative Study of Two Hospitals in Northern Morocco","authors":"Bougana Ihsane, Benabdelouahab Farid, Kacemi Loubna","doi":"10.11648/j.jctr.20210904.11","DOIUrl":"https://doi.org/10.11648/j.jctr.20210904.11","url":null,"abstract":": The increasing share of Thoraco-Abdomino-Pelvic-CT scan (TAP-CT) dose delivered to cancer patients requires particular vigilance. In fact, the radioprotection practices of our cancer patients are poorly respected, especially in terms of the number of acquisitions performed by practitioners. For instance, when performing a TAP-CT scan in cancer patients, the series without injection and the series with injection include arterial time, portal time, and rarely late time, lead to three to four acquisitions. Most practitioners do this routinely without considering whether these acquisitions are justified or not. This work assesses the practices carried out in the service of radiology in two hospitals in the province of Tetouan (northern Morocco). The overall purpose is to improve the radioprotection of our cancer patients. The retrospective investigation involved a total of 100 patients performed TAP examination. The PDL total is in the order of 500.72±15.08mGy.cm, and the effective dose (E) is of the order of 7.51±0.226mSv. Sex and ages variables did not show any significant differences according to t-test and ANOVA respectively. However, the variable \"number of acquisitions\" per examination showed a significant difference for PDL total and the Effective Dose (F=16.462; p<0.001). The MANOVA analysis showed that the variables gender and number of acquisitions showed a significant effect; (D gender =0.748; p=0.042) and (D number of acquisitions =11.888; p<0.001). By comparing the results of two hospitals, we found a large variation in the delivered doses. The radiologist himself seems to be a significant factor that can influence unnecessary acquisitions and therefore the total delivered dose. Consequently, the standardization of TAP protocols and the sharing of best practices between hospitals becomes a necessary approach towards dose optimization.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74414878","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}

Anticancer efficacy of the vaccine is implemented by breaking immune system tolerance to own tumor antigens due to the antigenic similarity between tumor and embryonic proteins. The experiments were conducted in Wistar female rats (age 2.5 months and weight 200-220 g, bred at the animal house of R. E. Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology). The care and use of the experimental animals have been performed in accordance with generally accepted international rules for conducting experiments in experimental animals. As an experimental tumor model, we have used Walker carcinosarcoma. In preclinical and clinical trials, success has been demonstrated in the use of a combination of anticancer vaccines with chemotherapy to achieve a synergistic effect, even if the dose and schedule of administration of the agents needed to be optimized. It has been shown that some drugs (doxorubicin, cyclophosphamide, docetaxel) induce immunological death of tumor cells, increase the expression of tumor-associated antigens, HLA-peptide complexes, thus sensitizing the tumor in vaccine-induced T-cell killing. It was determined that simultaneous administration of anticancer vaccines (regardless of the antigenic composition) and Doxorubicin resulted in a significant increase of survival and average lifespan of the experimental animals. The treated animals at the end of the experiment presented with increased cytotoxicity of lymphocytes and macrophages (both direct and antibody-dependent), suggesting a reduced level of immunosuppression in experimental animals. In the group of rats, receiving Dox, the serum had no effect on the activity of lymphocytes. These data suggest that during the development of tumor the serum accumulates humoral factors, capable of blocking lymphocyte activity. Yet, as a result of additional activation (due to anticancer vaccines), the conditions are provided when the inhibitory activity of humoral factors is eliminated. The combined application of chemo- and biotherapy based on anticancer vaccines of IEPOR series is an efficient and rather perspective method of inhibition of malignant tumor process. The optimal scheme of the combined therapy was developed that involved the administration of anticancer vaccines together with the application of chemotherapeutic agents. The augmentation of antitumor effect can be explained by the reduction of immunosuppressive activity of blood serum towards the effector cells of antitumor immunity, resulting from the additional signal to the immune system - use of anticancer vaccines.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72991950","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: An IRB approved prospective multisite registry enrolling stage I-IV TNBC patients from 2011-2018 was utilized. Demographics, treatments, genetic results, recurrence and survival were collected. OS was estimated according to the Kaplan-Meier method and compared between groups (gBRCA+and BRCA wild type, wt) by log-rank test. Cox regression model was used for univariate and multivariate analysis of factors associated with risk of death. Results: 100 patients with mTNBC were enrolled on the registry between 2011- 2018. For 100 patients, 20% (20/100) had de novo stage IV whereas 80% (80/100) had metastatic recurrence. 12% had gBRCA+ status; 72% were gBRCA wt type; and 16% had unknown gBRCA status. gBRCA+ patients were younger (49 vs. 57 years, p=0.02) but otherwise well matched to gBRCA wt including similar metastatic disease burden and prior treatments. No patients received a PARP inhibitor. With 31 months median follow-up, median overall survival was 21 months (95% CI [13-23] months) for all patients, 18 months (95% CI [15-27] months) for gBRCA wt patients and has not yet been reached for gBRCA+ patients (p=0.023). 3-year estimated OS is 63% in gBRCA+ versus 28% in gBRCA wt (p=0.02). On multivariate analysis, gBRCA+ was associated with reduced risk of death (HR=0.33; 95%CI [0.23-0.91], p=0.033). Conclusions: In patients with mTNBC gBRCA+ patients have a clinically significantly improved 3-year OS compared to gBRCA wt patients. Further research is needed to understand tumor and host biological reasons for this observation. As these patients are at risk for primary site progression and secondary breast and ovarian cancers, further research regarding the role of proactive surgical treatment in mTNBC with gBRCA mutation is warranted.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78864176","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}

In 2012, an estimated of 100,000 cases of invasive breast cancer were diagnosed in the United States. The histopathology type is predominantly ductal in about 70–80% of patients followed by invasive lobular carcinoma in 5–15% of case. Invasive papillary carcinomas of the breast are rare, accounting for less than 1-2% of invasive breast cancers. Occasionally the disease is found in men as well. Papillary carcinoma most frequently occurs in older and post-menopausal women. Triple assessment is essential to reach the diagnosis. The typical sonographic appearance of IPC is of hypoechoic area with soft tissue echoes emerging from the wall of the cyst. Invasive micropapillary carcinoma is a luminal-type breast cancer with a propensity for lymphovascular invasion and regional lymph-node metastasis. Intracystic papillary breast cancer (IPC) is best managed in the context of a multidisciplinary team. Surgical excision of the lump with margins in excess of 2 mm is considered satisfactory. Many studies suggest that papillary carcinoma may have a better prognosis than invasive ductal carcinoma (IDC). However, the little available information about papillary carcinoma of the breast underscores the need for further management related studies.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79185306","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 SEER-Medicare data was used to identify 142, 433 women age > 66 diagnosed with stage I-III breast cancer between 2007-2011. Receipt of GCC was determined according to evidence-based treatment guidelines. Cause-specific Cox proportional hazard multivariable regression models were used to estimate the association between GCC and the risk of BCSM, considering NBCM as a competing event, and NBCM, considering BCSM as a competing event, within five years of diagnosis or until end of follow-up. Among older women with breast cancer, 6.5% experienced BCSM and 11.9% experienced NBCM. GCC was associated with a 24% decreased risk of BCSM (AHR, 0.76; 95% CI, 0.71-0.82), but a 80% increased risk of NBCM (AHR, 1.80; 95% CI, 1.70-1.92). Receipt of adjuvant endocrine therapy was associated with an increased risk of BCSM and a decreased risk for NBCM. Receipt of chemotherapy was associated with an increased risk for BCSM and NBCM, while radiation therapy was associated with a decreased risk of NBCM. Women with a pre-existing dementia, arthritis, hypertension, stroke and increased comorbidity burden had an increased risk for BCSM. Most older breast cancer patients do not receive GCC, yet relatively few die from breast cancer. While GCC does decrease the risk of BCSM, the decision to treat should be made considering the patients existing health status, given that pre-existing comorbidity increases the risk for both BCSM and NBCM. Mortality differences associated with specific types of treatment may be attributed to patient selection for treatment based on worse cancer prognostic factors.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"05 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86482753","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}

Magnesium (Mg) supplementation is recommended for the avoidance of CDDP-induced nephrotoxicity. However, there is a concern that exposing cancer cells to Mg may suppress the antitumor effect of CDDP. Methods: Transporter expression, intracellular platinum and Mg levels, and cytotoxicity of CDDP after Mg exposure were assessed in human hepatocellular carcinoma (HepG2) and human ovarian carcinoma (2008) cells. Results: In HepG2 cells, Mg exposure significantly increased mRNA levels of multidrug and toxin extrusion 1 (MATE1), which mediates the renal excretion of CDDP, but did not alter its protein levels, including those of organic cation transporter 1 (OCT1), which mediates CDDP uptake in renal tubular and cancer cells, and multidrug resistance-associated protein 2 (MRP2), which mediates CDDP efflux in cancer cells. In 2008 cells, MATE1 protein expression could not be detected, but a slight increase in MRP2 and OCT1 protein expression was observed after Mg exposure. Intracellular Mg levels were significantly increased due to Mg exposure in both cells. However, intracellular platinum levels and cytotoxicity of CDDP were not affected in both cells, even with 2 mM Mg co-exposure. Conclusion: This study found that Mg exposure only slightly changed transporter expression and did not affect intracellular platinum levels and CDDP cytotoxicity in HepG2 and 2008 cells. Thus, Mg supplementation can be used to avoid CDDP-induced renal toxicity without affecting the accumulation of CDDP in cancer cells and its cytotoxicity.","PeriodicalId":93775,"journal":{"name":"Journal of cancer treatment and research","volume":"2005 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83015607","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}

There are several theories about their biological origin, one of them being alterations in the expression of miRNas This. was a retrospective multicentre study undertaken in patients with oligometastatic prostate cancer who were diagnosed and treated at one of 7 different Spanish healthcare centres. METHODS: The study included 22 patients; healthy and primary tumour biopsy tissue was analysed in 7+2 of them in order to determine if they had a characteristic microRNA expression profile. We quantified the expression of the following miRNAs: mir‑200a, mir‑200b, mir‑200c, mir‑210, mir‑95, mir‑96, mir‑654‑3p, mir‑543‑3p, mir‑21, mir‑16‑5p, mir‑191‑5p, and mir‑93‑5p, with the latter three being endogenous‑expression controls. RESULTS: Our results show that miRNA95, and to a lesser extent, miRNA654‑3p, were significantly underexpressed (or their expression was suppressed) in tumour tissue samples compared to normal perilesional tissue in all our patients; miRNA95 was underexpressed in 67% of the patients in our sample However, we detected no relationship between miRNA95 expression and the Gleason scores obtained for our patients.
