Abstract

ABSTRACTWe review the present knowledge of telomeres and telomerase with special attention to their role in hematological disorders especially bone marrow failure syndromes including acquired aplastic anemia and myelodysplastic syndromes, as well as acute and chronic myeloid leukemia. The current understanding on the role of telomere and telomeres dysfunctions in hematological disorders leads us to a better understanding on the pathology of the diseases as well as considering some possibilities to employ the measurement of telomere length and telomere activity in disease prognostication. Several treatment options targeting telomere and telomerase being developed are also reviewed.Keywords: telomere- telomerase- bone marrow failure syndromes- hematological malignancies

Abstract

The incidence of brain metastasis (BM) is reported to be increase about 20-40% over the last few years in patients with non-small-cell lung cancer (NSCLC).1 The use of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) in NSCLC patients with BM, especially those harboring EGFR mutations have been reported.

Abstract

Background: Colorectal cancer is the third largest incidence of cancer in the world and is the third most common cause of death in women and men . Five-year overall survival (OS) in colorectal cancer who have undergone metastasis was 10 % . Hematologic toxicity may be a marker of biological activity of cytotoxic drug on various types of cancer . Neutropeniaafter chemotherapy known to be associated with increased patient survival .Objective : To establish whether chemotherapy-induced neutropenia is predictive of better outcome in patients with metastatic colorectal cancer (mCRC).Methods: This research was a case-control study. Subjects were patients with metastatic colorectal cancer in the Cancer Instalation Center Tulip RSUP dr. Sardjito who meet the inclusion and exclusion criteria. Data were analyzed by bivariate analysis using chi square test and multivariate analysis with logistic regression.Results: Neutropenia present in 26 patients (32.5%) of the total 80 patients of the study. Neutropenia were significantly affect OS ( p = 0.001 and OR 7.73, 95% CI: 2.51-23.80). Multivariate logistic regression analysis showed neutropenia and the number of metastases affect OS with p <0.001 and p <0.003.Conclusion: Neutropenia occurring during the two first lines of chemotherapy for metastases colorectal cancer is associated with better survival. Variables that affect OS is the number of metastases and incidence of neutropenia after chemotherapy.

Abstract

Background. The mortality burden of cancer continues to increase in developing countries, most likely because of a late-stage at diagnosis. Identify the terminal stage is important in patients with advanced cancer because no longer aggressive therapy in patients with terminal cancer. Palliative prognostic score (PaP score)is a scoring system to predict the probability of survival within 30 days in patients with advanced cancer. PaP score divided into the heterogeneous patient sample into three iso-prognostic groups related to the chance of 30-days survival. Group A, score: 0 to 5.5 (the probability of survival within 30 days > 70%); Group B, score: 6-11 (the probability of survival in 30 days 30-70%) and group C, the score: 11.5 to 17.5 (the probability of survival in 30 days <30%).Aims. The aim of this study was to validate and to evaluate the prognostic accuracy of the palliative prognostic (PaP score) to predict 30-days survival in patients with metastatic cancers in Dr. Sardjito   General Hospital Yogyakarta.Methods. The design of this prognostic study was cohort, including patients with metastatic cancers who were visited in Tulip Hematology and Medical Oncology Clinic, inpatient and outpatient care in Dr. Sardjito General hospital during May 2015 until May 2016. The PaP score calculated in 159 consecutive patients with metastatic cancers. The positive predictive value of the PaP score was evaluated and survival analysis was performed to compare the survival of the three prognostic groups.Results. PaP score tested on 159 subjects with overall median survival was 90 days, 76 subjects categorized into group A, 22 subjects into group B and 61 patients into group C. The 30-day survival probability was 98.7% for group A (median survival could not be assessed), 63.6 % probability of 30-day survival for the group B with median survival was 35 days and for group C with 3.3% probability of 30-day and median survival was 6 days. These survival differences were highly significant (log-rank test of trends, X =203.97; P<0.0001).The positive predictive value of the PaP score in predicting 30-day mortality was 96.7% with an accuracy of PaP the score was 93.1%.Conclusion. PaP score was a valid test tool in determining prognosis in patients with metastatic cancers with high accuracy and precision in predicting 30-days survival.Keywords:  PaP score,  validation,  survival,  prognostic,  metastatic cancers.

Abstract

Background. Chronic Myeloid Leukemia (CML) is a myeloproliperative malignancy that is caused byreciprocal translocation between chromosomes 9 and 22 which form the BCR-ABL fusion gene. Most CML patients have a major type of BCR-ABL mutation. There are b3a2 and b2a2 types, which produce different oncoproteins in 25 amino acid elements. The expression of different proteins is thought to cause differences in clinical manifestations, laboratory, and prognosis. In CML, there are several prognostic scoring systems, including Sokal, Hasford, andEUTOS scores which combine clinical and laboratory parameters. The effect of this genomic breakpoint location on clinical and biological characteristics is still controversial.Aims. The aim of this study was to determine the comparison of prognostic scores between CML patients with b3a2 and b2a2 BCR-ABL mutation types in Dr. Sardjito General Hospital.Methods. This study was a cross sectional retrospective study used secondary data from medical records of Dr. Sardjito General Hospital, from March 2014 to April 2016. The prognostic score of Sokal, Hasford, and EUTOS was calculated in the BCR-ABL mutation type groups b3a2 and b2a2. Data were analyzed by Chi Square test.Results. A total of 113 CML patients were analyzed with 74 (65.5%) b3a2 mutation type groups and 39 (34.5%) b2a2 mutation type groups. Hemoglobin levels, leukocytes, platelets, basophils, and eosinophils did not differ significantly between the two groups of mutation types. Meanwhile, the statistical test for the phase of disease when the patient was first diagnosed in both types of mutations showed a significant difference (p = 0.005). More patients with types of b2a2 mutations came in the acceleration and blast crisis phases than b3a2 types. However, Sokal, Hasford, and EUTOS prognostic scores in the b3a2 mutation type group were not significantly different from the b2a2 group (p> 0.05).Conclusions. There was no significant difference in prognostic scores of CML patients with the b3a2 BCRABL mutation type compared with the b2a2 mutation type in Dr. Sardjito General Hospital Yogyakarta.
