Primary data from three different cancer populations: breast, prostate, and lung, will be examined. A number of experimental studies have been conducted to confirm the effectiveness of resistance training on pain relief as well as the biochemical pathways that relate to this process. In this review, we will examine 5 randomized controlled trials. For the purposes of this review, pain is defined as physical suffering or discomfort associated with illness. Pain is the body's natural signal, bringing attention to damage that has been sustained by tissues. However, chronic pain is common in the cancer population, and often serves no good purpose but instead will negatively impact both physical and mental health. The three types of pain: nociceptive, neuropathic, and inflammatory pathways have been investigated, and the knowledge of pain mechanisms allows for the understanding of how it is associated with pain. The purpose of this exploratory literature review is to give insight on how to maximize pain-relieving effects of resistance training. Research has indicated that resistance training modulates pain pathways by upregulating the release of pain-relieving substances including beta-endorphins, anti-inflammatory cytokines, and endocannabinoids. Understanding of the benefits of resistance training may be useful in relieving cancer pain, and reproducing effects of pain-relieving strategies while minimizing the symptoms related to cancer and its treatment.</p>","PeriodicalId":15267,"journal":{"name":"Journal of Cancer Therapy","volume":"14 2","pages":"80-101"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10373509/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10278825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These patients were grouped into two categories: the younger group (≤45 years) and the older group (>45 years). Clinicopathological features of epithelial ovarian carcinoma were analyzed in each age group. Cox proportional hazards model identified factors affecting survival and Kaplan-Meier survival curves with log rank test compared outcomes for each age group. Results: The median age of the 129 women was 46 years (IQR: 38, 56) and median time of follow-up was 9 months (inter-quartile range: 4, 26.5). We found a significant difference in the CA-125 level (p there was a higher probability of death among the older cohort. The 5-year overall survival rates for the younger age versus older group were 34.0%, and 11.7% respectively.

These mechanisms result in either an alteration of protooncogene structure or an increase in protooncogene expression. The role of epigenetic aberrancies in carcinogenesis has been described earlier however to clinicians, the biological implications of epigenetic therapies to prevent cancer and the mechanisms involved have been a mystery. Furthermore, there is no biomarker suggested to track the carcinogenesis steps long before cancer develops, and this has caused a significant lack of proactive and preventive measures to be taken as all recommendations in preventive oncology are either deficiently and blindly made or through screening methods which are too late in the game. Here we explored a very different approach by applying our deepest understanding of epigenetics and carcinogenesis and even further we developed a framework where our clinical findings could translate to the research and vice versa by generating advanced and novel hypotheses on “how we get cancer”, by exploring the relation between the host and the tumor cells in a way no one had perceived before. The role of specific cancer stem cell pathways is dissected and how to inhibit each of these initiators using multitargeted epigenetic therapies and off-label medications are explained. We should admit that without considering this sophisticated amazing biological network, cancer will remain an unsolved challenge. Further, we were able to solve this unsolved puzzle by bridging the gap from a hypothetical point of view/hypothesis to possibilities that explain the clinical findings we had observed, and conclude that such an approach can completely change the way practitioners are treating cancer.","PeriodicalId":15267,"journal":{"name":"Journal of Cancer Therapy","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135798568","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}

Methodology: We conducted a non-exhaustive preliminary study over a period of three months from the first of January to 31 March 2010 at four major hospitals in Dakar at the time. Results: Two hundred and eighty-nine cases had been identified: 44% of men (n = 127) and 56% of women (n = 162) with a sex ratio of 0.8. The ages ranged from 20 to 90 years with an average of 50 years. The main diagnostic mode was essentially histological, with 76% of cases (n = 219). The most frequent locations were: ORL (ENT meaning Ear, Nose and Throat) with 25% of cases, liver 7% and bronchopulmonary 4.5% of cases. In men, liver cancer was the most common location and women for cervical cancer with 16%. Squamous cell carcinoma was the most common histological type with 68% of cases followed by adenocarcinoma with 22% of cases. Thirty-eight percent of patients were classified as stage III and IV. A quarter of our patients had received palliative treatment. In contrast, 15 (15%) had received chemotherapy and 4% had received radiotherapy. Data collection was satisfactory.
