Hyperbaric oxygen treatment (HBOT) has been used to improve and cure disorders involving hypoxia and ischemia, HBOT enhances the amount of dissolved oxygen in the plasma and thereby increasing O2 delivery to the tissue. Studies on HBOT and cancer have mostly focused on whether enhanced oxygen may act as a promoter of cancer. As oxygen is believed to be required for all the major processes of wound healing, including angiogenesis, this particular idea would give the impression that HBOT will promote cancer growth and recurrence. Nevertheless, this is not the case since the use of HBOT in patients with malignancies should be considered safe and therapeutic. There is no evidence indicating that HBO neither acts as a stimulator of tumor growth nor as an enhancer of recurrence. On the other hand, there is evidence that implies that HBO has tumor-inhibitory effects, this manuscript pretends to expand our knowledge on the effect and the mechanisms behind tumor oxygenation by HBOT.","PeriodicalId":14957,"journal":{"name":"Journal of Analytical Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141351780","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}

Development of resistance to chemo- and radiotherapies contributes to these tumors’ aggressive phenotypes. Elevated lipid levels in gliomas have been reported for the last 50 years. However, the molecular mechanisms of how tumor tissues obtain lipids and utilize them are not well understood.In our study, 48.6% of phosphatidylcholines were significantly changed during an early stage of brain cancer in females, and 66.2% in males. As for lysophosphatidylcholines 57.1% metabolites were significantly changed in female, and 64.3% in male rats. We observed the most interesting results in the group of sphingomyelins, where 85.8% metabolites were significantly elevated during brain cancer. According to VIP projection, the most important metabolites were: PC ae C40:3, PC ae C38:1, PC ae C30:1, PC ae C38:3, PC ae C44:3, PC aa C40:2, PC aa C42:0, PC ae C30:2, SM C20:2, PC aa C42:1 in females, and PC ae C38:1, PC ae C40:3, PC ae C30:1, PC ae C42:1, SM C20:2, PC aa C34:4, PC ae C38:4, PC aa C32:2, PC aa C38:5, lysoPC a C14:0.

The precise aetiology is still unknown; however, a number of epidemiological variables have been proposed as potential risk factors. Modern imaging techniques are very helpful in the diagnosing process. Physician awareness is essential in order to raise suspicions about the potential for MPMT and to conduct appropriate investigations.

Additionally, true one cell techniques are playing an increasingly important role in current attempts to implement TOC metabolomic and proteomic studies, as well as emerging attempts to spatially resolve TOC information.

If only half of the losses is due to metastatic disease at diagnosis, then a share of the remaining deaths must be attributable to tumor recurrence after presumptively curative therapy of early-stage disease. If so, current management of the latter group is suboptimal for a considerable number of subjects, a perception which argues for an assessment of maintenance therapy. Moreover, most recurrences occur within 24 months after standard surgical and (neo)adjuvant therapies. \u0000Objective: To assess relapse-free and overall survival among patients with high-risk, resected tumors who did and did not receive maintenance therapy following completion of treatment according to accepted guidelines. \u0000Methods: Pertinent clinical details were collected on 85 subjects, 37 who were, and 48 who were not, treated with maintenance therapy. Descriptive statistical analyses related to survival outcomes were performed on accumulated data. Wilcoxon rank test and Fisher’s exact test were used to examine the continuous and categorical variables, respectively. Kaplan-Meier method and log-rank test were used to analyze between-group relapse-free and overall survival. \u0000Results: Of the entire cohort, 63 of 85 (74.1%) subjects have no evidence of disease, a median of 5 years from the end of adjuvant therapy. Kaplan-Meier analyses indicated statistically, but not necessarily clinically, non-significant differences in median 5-year relapse-free survival, 79.8% vs 69.2%, and overall survival, 87.8% vs 81.7% in the treated and untreated groups of patients, respectively. A total of 21 subjects died; three of seven (treated group) and all 14 (untreated group) due to cancer. \u0000Conclusion: Obscured is the hint that maintenance therapy is clinically more effective than what the p-value intimates. The results of this retrospective data collection and analyses suggest that some patients with early-stage, high-risk disease, will derive survival benefits with maintenance therapy.","PeriodicalId":14957,"journal":{"name":"Journal of Analytical Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88920629","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 object of the study were 172 patients with a verified diagnosis of BCC (T1N0M0, I stage), who received treatment from 2007 to 2022. PS «Photolon» (RUE «Belmedpreparaty», Republic of Belarus) was administrated intravenously at a dose of 2.0-2.5 mg/kg. The session of PDT was performed 2.5-3 h after intravenous injection of PS using semiconductor lasers (λ=660±5 nm) with exposure doses 50-250 J/cm² and power density – 0.15-0.5 W/cm². Frequency and severity of side effects after treatment session was assessed based on the criteria CTCAE (Version 4.03; 2010). The antitumor efficacy was evaluated 3 months after treatment. Clinical outcome was evaluated visually and morphologically by cytological or histopathological examination. Performance criteria were as follows (according to WHO, 1979). \u0000Results: The phenomenon of skin phototoxicity due to violation of the light regime (hyperemia, burning, slight swelling of the soft tissues of the face; CTCAE, I-II grades) was registered in 5.8% of cases (n=10). Serious adverse reactions (anaphylactic shock, Quincke's edema, severe pain syndrome) after the administration of PS and photoirradiation were not identified. Complete and partial regressions of tumors was observed in 93.0% and 4.7% of patients, respectively. The objective answer was 97.7%. The frequency of local relapses of the disease 1, 2, 3, 4 and 5 years after PDT was 3.1%, 3.1%, 4.6%, 4.6% and 6.9%, respectively. \u0000Сonclusion: PDT is a well-tolerated and highly effective therapeutic option in patients with BCC.","PeriodicalId":14957,"journal":{"name":"Journal of Analytical Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81976246","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}
