In addition, several studies have shown that it is often treated using chemotherapy drugs and targeted therapy, but these treatment methods have been reported to have side effects on the cardiovascular system. This indicates that there is a need to develop new and effective strategies to prevent the associated side effects. Therefore, this systematic review aims to obtain cardioprotection strategies to prevent cardiotoxicity in breast cancer patients receiving chemotherapy or targeted therapy. Methods: Data collection was carried out using the online database PubMed with keywords ((cardioprotection) AND (breast cancer therapy) AND (cardiotoxic) OR (Cardiac dysfunction.)) From the initial search, a total of 150 studies were obtained, while articles that did not meet the eligibility criteria were excluded. Furthermore, the articles were reviewed using full-text reading, leading to the inclusion of nineteen in this systematic review. Results: A total of eleven studies evaluated the effect of cardio-protective drugs on Anthracycline (ANT), and nine assessed Trastuzumab. The results showed that eight studies used Beta-blocker (BB) as cardio-protective strategies, while one, one, three, two, one, one, and one utilized Angiotensin receptor blockers (ARB), ARB + Beta-blocker, ACE-inhibitor (ACE-I) + Beta-blocker, ACE-I/ARB/BB, spironolactone, statin, and Dexrazoxane (DZR), respectively. In large reports, the risk of CTRCD was reduced by the use of a combination of RAAS inhibitors and Beta-blockers. Furthermore, spironolactone, statins, and DZR mitigated the decrease in LVEF compared to the control group in small studies. Conclusions: Based on the results, chemotherapy decreased left ventricular ejection fraction (LVEF) and induced heart failure. Furthermore, the review showed that a combination of reninangiotensin-aldosterone system (RAAS) inhibitors and Beta-blockers reduced CTRCD. Future studies in larger settings were needed to investigate the efficacy of other strategies, such as statins, Spironolactone, exercise, and DZR.","PeriodicalId":13489,"journal":{"name":"Indonesian Journal of Cancer","volume":"39 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946428","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 Asia, especially in Indonesia, the incidence of kidney cancer has not been widely reported. Therefore, researchers intend to investigate the characteristics of Kidney Cancer at Hasan Sadikin Hospital, Bandung, during the period 2015–2019. Methods: This research is a descriptive retrospective study taken from the medical records of patients with kidney cancer in the Department of Urology, Universitas Padjadjaran, Hasan Sadikin Hospital. The study was conducted from June 2019 until all the medical record data for the sample were fulfilled. The data included age, gender, and histopathological findings. Results: From the data collection, it was found that there were a total of 126 patients with kidney cancer, occurring in 83 male patients (65.8%) and 43 female patients (34.2%). The age group 0–10 years dominated the occurrence of kidney cancer, with 32 out of 126 patients (25.4%), followed by the 41–50 age group with 30 patients (23.8%), and the 21–30 age group had the fewest diagnoses of kidney cancer. A total of 78 patients (61.9%) were diagnosed with Renal Cell Carcinoma (RCC). Clear cell RCC was more common, with 64 cases (50.7%), compared to papillary RCC with 13 cases (10.3%) and Chromophobe RCC with 1 case (0.8%). The most commonly found kidney cancer was Wilm’s tumor, with 33 patients (26.1%), occurring in individuals under 20 years of age. Conclusion: This study found that kidney cancer is more common in males than in females. RCC is the most frequently diagnosed type, with clear cell subtype being predominant, especially in patients over 40 years of age. Wilm’s tumor dominates kidney cancer cases in individuals under 20 years of age.","PeriodicalId":13489,"journal":{"name":"Indonesian Journal of Cancer","volume":"17 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947533","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}

Neoplasm infiltration into the myocardium manifests through direct invasion, hematogenous spread, transvenous invasion through the great veins, or lymphangitic spreading in the mediastinal. Myocardial infiltration in lymphoma presents a grim prognosis and its treatment may be associated with specific risks, such as myocardial rupture. Various imaging modalities may detect cardiac involvement, with cardiac magnetic resonance (CMR) imaging considered the gold standard. CMR enables clear delineation of myocardial infiltration, making it valuable for local staging, pretreatment planning, and evaluating treatment response. Case Presentation: : A 37-year-old woman patient was diagnosed with primary mediastinal large B-cell lymphoma. Mild chest discomfort and shortness of breath were observed 3 months before hospital admission. A thorax CT scan showed a heterogeneous contrast-enhancing mass with a central necrotic area in the anterior mediastinum. Following thoracotomy and tumor debulking, the patient complained of severe crushing chest pain radiating to her back, accompanied by new T wave inversion on ECG and elevated cardiac troponin levels a week after surgery. Coronary angiogram results showed a normal coronary artery. Subsequent cardiac MRI showed tumor infiltration into the anterior pericardial space, as well as the myocardium of the left and right ventricles. Chemotherapy was promptly initiated, resulting in a gradual improvement of symptoms. Conclusions: In this study, we discuss the use of 3D-CRT in the re-irradiation of NPC with its limitation on obtaining optimum dose sculpture compared to more sophisticated and widely spread modalities like IMRT. However, with careful planning, we can still obtain optimum tumor dose, minimize OAR dose, and subsequently late toxicities that come after. We hope that this study can bring hope to centers with limited facilities, and we suggest further studies on reirradiation, especially in OAR dose tolerance guidelines. ","PeriodicalId":13489,"journal":{"name":"Indonesian Journal of Cancer","volume":"36 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946051","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}

Adisasmita, Septyana Choirunisa","doi":"10.33371/ijoc.v17i4.1053","DOIUrl":"https://doi.org/10.33371/ijoc.v17i4.1053","url":null,"abstract":"Background: Epithelial ovarian cancer is one of the most formidable lethal malignancies, with a 5-year survival rate of approximately 35% for advanced-stage ovarian carcinoma and a 10-year follow-up rate of about 18%. Although several regimens have been evaluated for improvement, relapse remains an inevitable challenge. Recently, specific prognostic factors related to “cell behavior”, including cell proliferation activity such as angiogenesis VEGF (vascular endothelial growth factors) have been recognized. Therefore, this study aims to predict relapse of epithelial ovarian cancer within two years of follow-up based on the expression of vascular endothelial growth factor A (VEGF-A) and vascular endothelial growth factor receptor-2 (VEGFR-2) at the mRNA and protein levels. Methods: This study was conducted at “Dharmais” Cancer Hospital (DCH) with a retrospective cohort design in patients with advanced epithelial ovarian cancer who received complete treatment. The role of angiogenesis factors on relapse in epithelial ovarian cancer in 2 years of observation was evaluated. Semiquantitative expression analysis of VEGF-A and VEGFR-2 (protein) was conducted through the immunohistochemical method using the avidin-biotinperoxidase complex (ABC) method. Meanwhile, the semiquantitative expression of VEGF-A and VEGF-R2 (mRNA level) was carried out using RT-PCR (Reverse Transcription- Polymerase Chain Reaction) - Zyber Green Bioline Kit - method, with specific primers. Results: From 2008 to 2012, only 20 patients were tested for the role of VEGF-A and VEGFR-2 on the incidence of relapse within two years of observation. Among the 20 patients examined for VEGF-A and VEGFR-2 expression, 50% remained disease-free for 20 months, resulting in a cumulative disease-free survival probability of 48.1% for the patient. Those with positive VEGF-A expression at the mRNA level had a shorter median disease-free survival time (18 months), with a lower disease-free survival probability. Patients who showed positive VEGFR-2 expression (at the protein level) had a shorter median disease-free survival time, a lower cumulative probability of disease-free survival (DFS), and a greater risk of relapse (3 times) than patients who did not express (negative) VEGFR-2. In addition, the ROC-based analysis was also performed. Conclusions: Expression of both VEGF-A and VEGFR-2 at mRNA and protein levels can be used as a predictor for relapse of epithelial ovarian cancer. This study showed that a positive VEGF-A expression at the mRNA level is associated with a twofold higher risk of relapse, while positive VEGF-R2 expression at the protein level is associated with a threefold shorter risk of relapse than negative expression.","PeriodicalId":13489,"journal":{"name":"Indonesian Journal of Cancer","volume":"11 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138947242","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}

Despite a heterogeneous profile, the relationship between microbiota and breast cancer is still not fully understood. Therefore, this study aimed to explain the major microbiota profile associated with breast cancer and explore potential biological connections Methods: Following the PRISMA guidelines, the literature review investigated the diverse composition of microbiota profiles in breast cancer patients compared to those in normal conditions. Utilizing the PICO framework, a comprehensive search was conducted on the Pubmed and Google Scholar databases. The searches were restricted to open-access articles from the last 5 years. Additionally, critical appraisals are conducted for quality assessment. Results: A total of 145 articles were identified using the relevant keywords, out of which 17 successfully passed filtering and screening for inclusion in the review. Major microbiota observed in breast cancer patients included firmicutes, proteobacteria, actinobacteria, and bacteroidetes. The microbiota profile was influenced by factors such as cancer subtype, menopausal history, and tumor severity. These microorganisms play a role in the inflammatory response to their metabolite products and modulate hormonal changes, potentially enhancing tumor survival. Conclusions: Generalizing the expression of microbiota profile both in the gut or its tissue might be challenging due to its multifactorial nature, dependent on patient characteristics such as age, menopausal status, BMI, tumor grade, and subtype. The study suggests that the major microbiota that shows increased prevalence in breast cancer include firmicutes, proteobacteria, actinobacteria, bacteroidetes, and blautia, each playing a distinct role in the developmental process. ","PeriodicalId":13489,"journal":{"name":"Indonesian Journal of Cancer","volume":"86 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138945462","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}
