Depending on the stage of disease, treatment includes surgery, chemotherapy, and radiotherapy. Chemotherapy and radiotherapy can induce differentiation of tumor cells to rhabdoid morphology that can masquerade as rhabdoid tumor of the kidney. We report a rare case of WT with rhabdoid differentiation subsequent to treatment with neoadjuvant chemotherapy. Rhabdoid tumor of the kidney was initially considered a sarcomatous variant of WT, however was later classified separately due to distinct behavior. This makes it challenging to differentiate from WT with rhabdoid differentiation which is important as that would also affect the aggressiveness of treatment and prognosis.","PeriodicalId":16923,"journal":{"name":"Journal of Radiation and Cancer Research","volume":"100 48","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141664219","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 is no standard of care for patients with recurrent high-grade glioma. Treatment strategies include resection, re-irradiation, systemic agents, and intratumoral thermotherapy using magnetic iron-oxide nanoparticles (nanotherapy). A small percentage of patients can undergo repeat surgery and re-radiation is also a matter of concern due to anticipated toxicities. However, advancements in radiation technology have made people more willing to consider re-irradiation. In this study, we retrospectively analyzed patients who underwent re-irradiation for high-grade glioma. In total, five patients were included in the study. All five patients had anaplastic astrocytoma. All patients were considered for surgery, followed by radiation therapy during the initial treatment. Three patients had an average of 4 years of symptom-free survival, while the other two had symptoms ranging from moderate to severe. Three of the five patients died within 1 year of taking the re-radiation; however, two patients are still in follow-up.","PeriodicalId":16923,"journal":{"name":"Journal of Radiation and Cancer Research","volume":"65 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663046","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}

Leiomyosarcomas of the bone are extremely rare. We report a rare case of leiomyosarcoma of the tibia. A 71-year-old male patient presented to our department with the chief complaint of painful swelling over the left knee for 3 months. Magnetic resonance imaging (MRI) with gadolinium of the left knee showed a 7.5 cm × 6 cm × 5 cm bony lesion associated with a soft-tissue component in the upper epimetaphysis of the left tibia. A biopsy of the lesion showed a malignant spindle cell tumor, following which the patient was offered two cycles of adriamycin single-agent chemotherapy. Postchemotherapy MRI showed progression of the lesion to the size of 9.9 cm × 8.2 cm × 6.5 cm, involving the articular surface of the tibia. Following progression, the patient was planned for wide local excision of the lesion, which turned out to be leiomyosarcoma Grade III with a mitotic rate of 30/10 high power field, and the size of the lesion’s largest diameter was 8 cm with soft-tissue infiltration. Margins were clear, and there were no adverse features of lymphovascular and perineural invasion or articular cartilage infiltration. Immunohistochemistry markers were used to confirm the bony origin of the leiomyosarcoma, which is extremely rare. Actin, calponin, and S 100 were positive, and CD 34, SOX 10, and SATB2 were negative. All surgical slides examined showed no evidence of osteoid. Postoperative positron emission computed tomography revealed no evidence of any disease, and thereby, the plan was to keep the patient on close follow-up. Multiple studies have reported a poor response of leiomyosarcoma of the bone to chemotherapy, as well as minimal overall survival benefit. The radical surgical excision of a bony lesion with the achievement of negative margins is similar to that of other primary malignant bone tumors. Sarcomas are generally believed to be radioresistant in nature, and thereby, their role in either a neoadjuvant or adjuvant setting is controversial. A multidisciplinary approach should be used in such rare cases as leiomyosarcomas of osseous origin.","PeriodicalId":16923,"journal":{"name":"Journal of Radiation and Cancer Research","volume":"51 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141383857","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}

By integrating clinical and pathologic features to inform treatment decisions, including concurrent chemoradiation, chemotherapy, targeted therapies, endocrine therapy, and immunotherapy, there is potential to enhance EC management and provide patients with more effective and tailored treatment options.

Thus, new knowledge is generated by research and clinical experience. Statistical methods used in medical research play a vital role in medical research to draw a meaningful conclusion about research. Analyzing data and interpreting results is the most exciting stage of research, but it is not possible for everyone. It is possible for those who is having deep knowledge and to know the applicability of statistical methods used in medical research. Commonly used statistical methods in medical research are descriptive and inferential statistical methods. In descriptive statistical methods, we describe our data by the organization of our data in the form of tabulation and diagrams, measures of central tendency, dispersion, condensation, and measures of correlation. In inferential statistics, we draw a meaningful conclusion whether our treatment or procedure used in medical research gives a fruitful outcome or not. It is possible only when we have a good knowledge and skill of statistical methods used in basic research and it allows our clinical researchers to draw accurate and reasonable conclusions. Statistics provides us with sound methods in collecting data about observing health-related events, which in turn helps us in summarizing and analyzing the results so as to draw valid inferences regarding the hypothesis of our research. During the research, scientists used different statistical methods such as independent t-test or Student's t-test and Chi-square test to compare the different treatments used in the experimental studies to check whether there was a significant difference in our treatment or not. The main role of a cancer registry is to capturing a clear and complete picture of the cancer burden. To show how confident the researchers are that the results did not happen by chance, they use confidence intervals. For example, 95% confidence means that the researchers are pretty sure that the result has not happened by chance. The motive and aim of my review article are only to aware the researchers to know the importance and applicability of these statistical methods used in medical research and cancer registries.","PeriodicalId":16923,"journal":{"name":"Journal of Radiation and Cancer Research","volume":"32 1","pages":"111 - 115"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78998287","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}
