Plerixafor is a stem cell mobilising agent, and when administered along with G-CSF has been shown to improve CD34+ stem cell collections in lymphoma and multiple myeloma patients compared to G-CSF alone. Patients who failed to mobilize 6 cells/kg on Day 1 collection received Plerixafor and G CSF for further collections. Study population was divided into two groups as plerixafor yes (PY) who are poor mobilizers and Plerixafor No (PN) who are good mobilizers. Out of 49 patients, 28 patients were in PY group and 21 patients in PN group. Median value of apheresis CD34 of day 1 was 1.75 (range 0.258 to 8.52) in PY group and 2.63 (range 1.06 to 6.29) in PN group and that of day 2 was 3.845 (range 0.317 to 13.89) in PY group and 3.18 (range 0.88 to 6.348) in PN group. Median value of total apheresis CD34 was 8.10 (range 4.33 to 18.66) in PY group and 7.58 (range 4.06 to 9.8) in PN group. Median day of neutrophil engraftment was 11.5 (range 9 - 22) in PY group and 11 (range 9 - 36) in PN group whereas median day of platelet engraftment was 14 (range 9 - 98) in PY group and 13 (range 11 - 98) in PN group. It can be concluded that the use of plerixafor not only enabled poor mobilizers of Lymphoma and Multiple Myeloma to collect adequate stem cells to proceed to ASCT, but also had early neutrophil and platelet engraftment which was comparable with good mobilizers.

Background:?The role of chemotherapy in Gastric Cancer is constantly evolving?with various neoadjuvant and adjuvant strategies. Several chemotherapeutic agents are used in the treatment of locally advanced gastric cancer (LAGC) namely Platinum based compounds (Cisplatin, Oxaliplatin), Fluoropyrimidines like 5-Flurouracil [(5-FU), Capecitabine)], Taxanes (Docetaxel) and Anthracyclines (Epirubicin). Various doublet and triplet combination chemotherapy regimens have been used for neo-adjuvant chemotherapy (NACT) in LAGCs. In this study we evaluated the safety and efficacy of docetaxel based triplet regimen DOF [Docetaxel, Oxaliplatin, 5-Fluorouracil] in LAGC. Material and methods:?50 Newly diagnosed patients of Locally Advanced Gastric Cancer (stage II or III) deemed fit to receive chemotherapy were included in our study. After 3 cycles of neoadjuvant chemotherapy, patients were assessed based on radiological and pathological response.?Results: 50 Patients were included in our study of which majority were male (32), median age at presentation was 55 years and 24 patients presented with a history of gastrointestinal reflux disease (GERD). The most common hematological toxicities observed in our study were anemia (61.2%), neutropenia (42.6%, febrile neutropenia constituted 6%) and thrombocytopenia (13.2%). The most common gastro-intestinal [GI] toxicities observed in our study included nausea (69.2%), vomiting (31.2%), diarrhea (34%), oral mucositis (14%) and constipation (6.6%). We found that safety profile of DOF regimen was favorable with majority of patients tolerating the regimen well. The Overall Response Rate (68%), Disease Control Rate (96%) and Resectability Rate (80%) were higher compared to western studies. Pathological CR (17.5%), ypN0?disease status (42.5%) and nodal down staging (52%), all showed positive correlations with survival outcomes. Conclusion:?DOF regimen is an effective and feasible option for neoadjuvant treatment of LAGC in an Indian population

Impact of MGMT Promoter Methylation as a Prognostic Marker in Patients with High Grade Glioma: A Single-Center Observational Study

引用

Journal of Cancer Therapy 2019年第10期10卷 806-814页

作者： Vinu Sarathy Srinivasa Belagutty Jayappa Bhanu Lalkota kiran pura krishnamurthy Vishal Kulkarni Samuel Luke Koramati Nasiruddin Mohammad Radheshyam Naik Department of Medical Oncology Health Care Global Enterprises Ltd. Bangalore India

Objectives: 1) To correlate the methylation status of the O-6-methylguanine-DNA-methyltransferase (MGMT promoter gene) and response to alkylating agent-based treatment in high-grade gliomas. Background: The MGMT gene is epigenetically silenced by promoter hypermethylation in gliomas and this modification has emerged as a relevant predictor of therapeutic response. Methods: 20 cases of high-grade glioma were analyzed for MGMT promoter methylation by methylation-specific PCR. Response to treatment and overall survival data were recorded and data analysed. Results: MGMT promoter methylation was found in 60% of gliomas by methylation-specific PCR. The mean survival time of glioblastoma patients submitted to adjuvant therapy was significantly higher among patients with MGMT promoter methylation (P = 0.035) and methylation status was an independent predictive factor that was associated with improved prognosis. Discussion and Conclusion: MGMT promoter methylation status was a more reliable predictor of response to adjuvant therapy and prognosis of high-grade gliomas. A subset of patients received irinotecan and bevacizumab in the second line setting and patients with unmethylated MGMT seemed to do better than the MGMT promoter methylated group.
