{"title":"Nanotherapeutics to cure inflammation-induced cancer","authors":"Rajiv Kumar","doi":"10.25082/ccr.2024.01.001","DOIUrl":"https://doi.org/10.25082/ccr.2024.01.001","url":null,"abstract":"Aims: Nanotherapeutics are being explored as a potential solution to treat inflammation-induced cancer. Nanotherapeutics enhance innate immune cells' immunity, enabling them to fight tumors effectively. These cells secrete specific chemicals like cytokines, allowing them to replicate quickly and respond to future threats, making them suitable for immunotherapy.Methods: Nanotechnology can significantly improve human health by enhancing infection detection, prevention, and treatment. Nanomedicines, composed of restorative and imaging compounds in submicrometer-sized materials, aim to deliver effective treatments and limit inflammation in healthy body areas. Combining nanotechnology and clinical sciences, nanoparticles are suitable for gene therapy and have been developed for treating various diseases, including cancer, cardiovascular, diabetes, pulmonary, and inflammatory diseases.Results: Neutrophils and their offspring, including films and extracellular vehicles, are crucial drug transporters for enhanced growth therapy. Tumor microenvironment inputs can modify tumor-associated neutrophils (TANs), which are essential for tumor growth and healing. Human tumor intratumor heterogeneity is crucial for tumor growth and healing. Nanomedicines have shown potential in targeted delivery, toxicity reduction, and therapeutic effectiveness enhancement. However, clinical relevance and efficacy remain inadequate due to a lack of understanding of the interaction between nanomaterials, nanomedicine, and biology. The diverse biological milieu impacts the dynamic bioidentity of nanoformulations, and their interactions can modify therapeutic function or cellular absorption.Conclusion: Nanotechnology holds great promise for improving human health by detecting, preventing, and treating infections. Nanomedicines, a fusion of clinical sciences and nanotechnology, use submicrometer-sized transporter materials for therapy delivery and reducing contamination. Nanoparticles' small size and high surface-to-volume ratio can benefit gene therapy. Research has led to a wide range of nanomedicine products globally.","PeriodicalId":72728,"journal":{"name":"Current cancer reports","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141687865","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}

Therefore, this study aims to investigate breast carcinomas as a function of hormone receptors (estrogen and progesterone) in the Democratic Republic of the Congo (DRC), which can contribute to better management of breast cancer cases in the country.Methods: We conducted an analytical cross-sectional study from 2014 to 2016 in the cities of Kinshasa and Lubumbashi. Using non-random sampling, we collected 86 cases of breast carcinoma.Results: The study found that out of the 86 cases of breast carcinoma, 33 patients (38.3%) had both types of hormone receptors (ER+/PgR+), while 37 patients (43.0%) had negative results for both receptor types (ER-/PgR-). Additionally, 15 patients (17.4%) had only estrogen receptors. The study did not find any significant association between the presence of estrogen receptors and patient age, T stage, histological type, and Ki67 proliferation index. However, the study did observe that estrogen receptors were significantly more present in grade I and II tumors (74.4%) than in grade III tumors (40.4%) (Odds ratio=4.3 [1.7-10.8]; p=0.003).Conclusion: The findings of this study demonstrate a high prevalence of hormone receptors in breast cancer cases in the DRC. Additionally, the study revealed a significant association between the presence of estrogen receptors and tumor grade, underlining the relevance of these markers in the characterization and treatment of the disease.","PeriodicalId":72728,"journal":{"name":"Current cancer reports","volume":"76 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140377953","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}

Bhaskar","doi":"10.25082/ccr.2023.01.005","DOIUrl":"https://doi.org/10.25082/ccr.2023.01.005","url":null,"abstract":"Despite breakthroughs in screening, identification, and therapy, pancreatic cancer (PC) remains a serious issue in cancer-related mortality. This comprehensive review investigates the long-term and latent effects of chemotherapy in PC, focusing on commonly used medicines such as gemcitabine, docetaxel, irinotecan, nab-paclitaxel, and others. Gemcitabine, a common PC medication, causes a variety of adverse effects, including myelosuppression and weariness. Combination therapy, such as docetaxel and irinotecan, enhance toxicity, resulting in problems such as neutropenia and gastrointestinal difficulties. Significantly, chemotherapy-related complications, such as thrombosis and cardiac difficulties connected to paclitaxel, present serious concerns. Erlotinib, gefitinib, vatalanib, and sunitinib studies show significant side effects. Despite ongoing challenges, determining the causes of the low objective response rate in gemcitabine-refractory patients remains challenging. The study emphasizes the importance of future advances in cancer etiology, arguing for large, straightforward studies examining combination chemotherapies to improve tolerance and minimize chemotherapy-induced sequelae. This overview serves as a thorough guide for physicians, researchers, and policymakers as they navigate the complex terrain of PC chemotherapy, providing significant insights to improve patient care.","PeriodicalId":72728,"journal":{"name":"Current cancer reports","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140448725","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}

Kathuria-Prakash, Robin Hilder, Melissa G. Lechner, Alexandra Drakaki","doi":"10.25082/ccr.2023.01.004","DOIUrl":"https://doi.org/10.25082/ccr.2023.01.004","url":null,"abstract":"Introduction: Immune checkpoint inhibitors (ICI) are widely used cancer therapies that harness the immune system to target malignant cells but subsequently can cause serious off-target immune-related Adverse Effects (irAEs). Patients with pre-existing autoimmune disease have historically been excluded from ICI clinical trials due to scientific concerns over increased risk of irAEs and flares of underlying autoimmune disease.Methods: We designed a retrospective, single-center, case-control study at a large, academic medical center to evaluate the incidence and severity of irAEs in patients with pre-existing autoimmunity compared to controls. Controls were matched 2:1 for age, sex, cancer histology, and ICI class. Patients were identified with ICD 9 and 10 codes followed by manual chart extraction. Cases were defined as patients with pre-existing, systemic autoimmunity. The primary outcome was severe irAE (Grade 3 or higher by Common Terminology Criteria for Adverse Events) within 6 months of ICI therapy. Secondary outcomes included response to ICIs, resolution of the irAE, ICI rechallenge success, and survival. Statistical analyses were performed by Chi-square, Fishers exact, Mann-Whitney, and Log-rank tests.Results: Of 3,130 patients treated with ICIs from 2015-2021, 28 cases with pre-existing autoimmune disease were identified and were matched with 56 controls. Pre-existing autoimmune conditions included antiphospholipid syndrome, inflammatory polyarthritis, juvenile rheumatoid arthritis, multiple sclerosis, psoriatic arthritis, rheumatoid arthritis, and type I diabetes. Multiple cancer histologies, including genitourinary, gynecologic, head & neck, hepatobiliary, lung, melanoma, and pancreatic, were represented. Six of 28 cases (21.4%) experienced severe irAEs compared to 9/56 (16.1%) controls; the odds of developing a severe irAE were not significantly different (OR 0.43, 95% CI 0.083-2.33, p = 0.627, ns). Moreover, there were no significant differences in overall survival or tumor response between the two groups. The majority of irAEs resolved without long-term sequelae (66.7% of cases, 55.6% of controls). The majority of patients who were rechallenged with ICIs were successful in continuing therapy (66.7% of cases, 100% of controls).Conclusion: Our study suggests that patients with pre-existing autoimmune disease can be treated with ICI cancer therapies and experience rates of severe irAEs and overall survival that are similar to those of the general population. These data can aid oncologists in discussing risks and benefits of ICIs when treating patients with pre-existing autoimmunity and solid tumors.","PeriodicalId":72728,"journal":{"name":"Current cancer reports","volume":"8 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488876","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: From January 2010 to June 2022, patients with potentially surgically resectable HCCA who underwent preoperative PVE and BD were analyzed. Type of initial BD, time interval between BD and PVE, changes in future liver remnant (FLR), time interval between BD, PVE and resection, and complications were recorded. Patients were divided into 3 groups based on the BD-PVE interval: Group A: simultaneous BD and PVE or within 7 days (d), n = 6; Group B: d ≥ 7 to ≤ 30, n = 7; Group C: d > 30, n = 14). Primary endpoints were post-PVE complications, FLR change, and resection rate. Secondary endpoints were Clavien-Dindo ≥ 3, Grade B/C Post Hepatectomy Liver Failure (PHLF) and 90 days mortality rate. Results: A total of 27 patients (mean age = 64.4 +/- 11.2 years) underwent both BD and PVE prior to hepatectomy. Mean degree of hypertrophy at 4-6 weeks post-PVE was 10.4 +/- 3.7% with no significant difference between the 3 groups (p > 0.05). Resection was 67% in Group A, and 57% and 36% in groups B and C respectively (p < 0.05). Time to surgery was 38.5 +/- 12 days in Group A, and 60 and 147 days in groups B and C respectively (p = 0.002). No major post PVE SIR complication was reported in group A. Overall rate of Grade III/IV Clavien-Dindo complication was 61.5% with no difference among the three groups (50%, 75%, and 60%; groups A, B and C, respectively). Overall PHLF Grade B/C was reported in 46.2% of patients. No patients in Group A demonstrated Grade B/C PHLF. Conclusion: Simultaneous BD and PVE is safe and reduces the time to surgery, which may help contribute to a higher rate of surgical resection.","PeriodicalId":72728,"journal":{"name":"Current cancer reports","volume":"10 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139607213","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}
