Methods: Two groups of patients were identified according to the date of occurrence of relapse after autologous transplantation, within less than 24 months, defining early relapse (G1), or after more than 24 months, defining late relapse (G2). Results: A total of 307 patients with MM were enrolled, including 93 patients (30%) who had experienced relapse. There were 56 early relapses (18%) and 37 late relapses (12%). In G1 the median follow-up was 19.5 months (3-93), as compared to59 months (24-117) in G2. The median of PFS was 18 months (14.8-21.14) in G1 and was not attained in G2 (p=0.0001). The median of OS was 29 months (18.2-39.7) in G1 and was not attained in G2 (p=0.0001).

About 80% of endometrial carcinomas are preceded by atypical endometrial hyperplasia. PTEN is a tumor suppressor gene involved in many vital intracellular biological processes. PTEN is altered in more than 45% of endometrial carcinomas. The aim of this study was to evaluate the value immunohistochemical expression of PTEN in normal, hyperplastic and neoplastic endometrial tissues. Methods: Ninety-two endometrial samples were enrolled in this study. They were classified into normal (n=6), hyperplastic (n=54) and neoplastic (n=32) endometrial tissues. Formalin-fixed and paraffin-embedded tissue blocks were prepared from each specimen. Tissue sections were immunohistochemically stained by anti-PTEN antibodies. Results: In our study; PTEN was strongly expressed in all normal and hyperplastic endometrial tissues without atypia. Staining intensity was decreased in atypical endometrial hyperplasia and endometrial carcinoma (p<0.0001). we also detected an inverse relationship between PTEN expression on one side and tumor grade (p=0.006), stage (p< 0.0001) and myometrial invasion (p=0.001) on the other side. Conclusions: Our study proved that immunohistochemical expression of PTEN is down-regulated in atypical hyperplastic and neoplastic endometrial tissues.

Autophagy plays a dual role in tumor progression. In the early stages, it prevents tumor formation, while in the advanced stages it promotes tumorigenicity. This study aimed at investigating the role of autophagy in different stages of melanoma and evaluating the relationship between autophagy and clinicopathological factors. Methods: ATG5 and BECN1 genes expression in melanoma tumors were evaluated in a retrospective study of 5 years in the cancer institute of Tehran, Iran. The autophagy-related proteins and the correlation with clinicopathological data were also investigated in a tissue microarray series of 52 melanoma tumors following by immunohistochemical staining for the autophagy-associated proteins p62/SQSTM1 (p62), LC3II and Beclin-1/BECN1. The possibility of autophagy biomarkers was also predicted by ROC curve analysis. Results: ATG5 and BECN1 gene expression decreased in melanoma tumors in comparison with tumor margins. However, BECN1 expression at the protein level increased with tumor progression. The expression of LC3II also raised while the p62 level declined as the tumor progressed, suggesting an increased autophagy activity during tumor development. Furthermore, melanoma ulceration was positively correlated with BECN1, LC3II and p62 expression with p<0.05, though the melanoma mitotic rate and thickness did not significantly correlate with autophagy–related proteins expression. Conclusions: Autophagy-related proteins are suggested as potential prognostic factors in melanoma and could be considered as a therapeutic target.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82198090","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}

It is the 10th biggest cause of death worldwide. Objective: This review focuses on the relationship between oxidative stress and the risk of developing of acute and chronic hepatitis B complications. Methods: The data were collected by searching Science Direct, Google Scholar, PubMed, Scopus, Springer and National Center for Biotechnology Information (NCBI). The Keywords used as search terms were “Hepatitis B”, “Acute and Chronic hepatitis”, “HBV induced inflammatory reaction”, “hepatitis B and Oxidative stress” and “free radical induced hepatitis B complication”.Results: Chronic infections with chronic active hepatitis, acute or sub-acute hepatic necrosis, cirrhosis, liver failure, and hepatocellular cancer in people with hepatitis B infection are all complications of viral hepatitis. Extrahepatic complications are common in patients with chronic hepatitis infection, including cryoglobulinemia, non-Hodgkin lymphoma, focal lymphocytic sialadenitis, autoimmune thyroiditis, porphyria cutanea tarda, and lichen planus. Wide variations in hepatitis B incubation durations show that the redox state of cells can influence viral activity. Viral replication is more active with more severe oxidative stress, with dispersion from lysed or dead cells. Although the precise mechanisms of ROS participation in the pathogenesis of inflammatory disorders are still debated. Conclusion: Viral activity can be determined by the oxidative stress status of the cells which can be the main cause of the development of hepatocellular carcinoma related to the complications of acute and chronic hepatitis B.","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76837571","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 early consequences of induction chemotherapy are represented by pancytopenia with severe immunosuppression, which favors the emergence of so-called “opportunistic” infections and in particular invasive fungal infections (IFI) such as invasive aspergillosis (IA). This justifies the implementation of early, empirical, pre-emptive or prophylactic antifungal treatment. The objective of this study is the evaluation of a comparative study before and after the use of primary prevention with posaconazole versus fluconazole, in terms of incidence and mortality of invasive fungal infections (IFIs) during AML inductions, in real life in Algeria. Patients and methods: This study was performed in two periods in the 2 centers concerning the same AML patients receiving the same induction chemotherapy (daunorubicin 60 mg/m2 for 3 days and cytarabine 100 mg/m2 for 7 days) but with a different type of hospitalization with common rooms for Tlemcen and protected single rooms for Oran. Period 1: The retrospective study was performed from 2014 to 2016 and involved 188 patients. 70 patients were hospitalized in a common room (Tlemcen) and 118 patients in a protected single room (Oran). All patients received as primary IFI prophylaxis fluconazole 400 mg/day. Period 2: The prospective study was conducted from April 2017 to September 2018 and involved 55 patients. Fourteen patients were hospitalized in Tlemcen and 41 patients in an Oran. These patients received posaconazole prophylaxis at a dose of 200 mgx3/day. The evaluation and comparison of descriptive and incidence data was performed using Chi2 statistical tests using SPSS version 19 software. Overall survival (OS) were calculated using the Kaplan-Meier estimate and were compared using the log-rank test with a significance level α of 0.05. Results: Period 1: The incidence rate of IFI: 34% at the Oran hospital versus 49% at the Tlemcen hospital (p=0.049). Among the 74 patients who presented with IFI, 39 (53%) died from IFI as the main cause of death, among these deaths, 16 (40%) were recorded at Oran and 23 (68%) at Tlemcen (p=0.011). Period 2: The IFI rate with fluconazole was 39% and that observed with posaconazole 22% (p=0.001) and the cumulative incidence was 39% at 21 days versus 10% at 15 days (p=0.046) with a highly significant decrease in IFI-related deaths: 53% versus 25% (p=0.004). Conclusion: This work has demonstrated the interest in terms of IFI incidence (17% versus 33%, p=0.04) and IFI-related mortality of posaconazole prophylaxis (25% versus 53%, p=0.004) used during AML in the context of hospitalization in common rooms. Furthermore, this work highlights that the combination of posaconazole prophylaxis and hospitalization in a protected single room allows an optimization of the management of this type of patients. \u0000  \u0000  \u0000 ","PeriodicalId":8848,"journal":{"name":"Asian Pacific Journal of Cancer Biology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83396322","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 type of anemia in lymphoma is predominantly anemia of chronic disease. Severe anemia is also often associated with advanced stages leading to poor prognosis and survival as well as a worse quality of life. Objective: In this study, we aimed to observe the incidence of anemia in lymphoma and to identify any associated clinical and laboratory factors. Methods: Data from lymphoma patients admitted between 2012 to 2018 with complete hemoglobin (Hb) levels were collected from the medical records in Dr. Sardjito Hospital, Yogyakarta, Indonesia. Clinical and laboratory parameters included were age, sex, nutritional status, Ann Arbor staging, extranodal involvement, number of extranodal sites, Lactate Dehydrogenase (LDH) level, Eastern Cooperative Oncology Group (ECOG) performance status, platelet count, absolute lymphocyte count (ALC), white blood cell count (WBC), and lymphoma prognostic score (Non-Hodgkin Lymphoma/NHL using Index Prognostic International (IPI), Hodgkin’s Lymphoma/HL using International Prognostic Score (IPS)). Statistical analysis was done to observe the difference in any parameters between patients with anemia and non-anemia. Logistic regression was employed to model the relationship between associated or predictive factors and anemia incidence. Results: Six hundred eleven (611) lymphoma patients were involved in this study, 296 (48.5%) had anemia and 314 (51.5%) did not. Anemia was more prevalent in HL (17/ 33 cases or 51.5%) than in NHL (272/ 564 cases or 48.1%). Patients with anemia frequently presented with mild anemia in 142 (48%), followed by moderate anemia in 139 (46.9%). The incidence of anemia were significantly associated with male sex, advanced Ann Arbor stage (III-IV), underweight, elevated LDH level, abnormal platelet, absolute lymphocyte counts less than 600/mm3, elevated WBC count more than 15,000/mm3, and high total prognostic score (>3). Multivariate analysis demonstrated low or elevated platelet (P=0.044; 95% CI=1.03-8.09) as an independent predictor, meanwhile lymphocytopenia as protective factor (OR=0.05; 95% CI=0.00-0.54; P=0.013). Conclusion: Anemia commonly occurs in Indonesian lymphoma patients. There is an association and increased risk to develop anemia in male, Ann Arbor stage III-IV, underweight, elevated LDH, abnormal platelet, leukocytosis, and high total prognostic score.
