Brainstem glioma is rare tumour in adults accounting for 1% -2% of intracranial gliomas. In this case study, a 28-year-old female diagnosed with BG, and lesions were observed in the pons and medulla region of the brain stem. She was initially treated with radiotherapy (54 Gy in 30 fractions for 6 weeks) but no change in her clinical condition and size of tumor was observed. Temozolomide (250 mg/daily for 5 days) was prescribed as first line chemotherapy. After completion of three cycles of Temozolomide, patient presented with diplopia and MRI showed increase in the size of lesions. After unsatisfactory response to radiation and chemotherapy, the patient was treated with Nimotuzumab therapy. MRI scan demonstrated the reduction of lesion size after 8 cycles of Nimotuzumab (200 mg/week). This treatment continued for another 8 cycles and the MRI scan of patients showed a significant reduction in lesion size. Nimotuzumab was found to be an effective and safe treatment option for brainstem glioma patient who was resistant to radiotherapy and chemotherapy.
Introduction Philadelphia chromosome positivity (Ph + ) is a poor prognostic feature in adult acute lymphoblastic leukemia (ALL). Allogenic hematopoietic stem cell transplantation in first complete remission (CR1) is recommended. There is limited literature on the role of consolidation autologous stem cell transplantation (ASCT). This study was undertaken to assess the potential of consolidation ASCT in CR1 in adults with Ph + ALL. Objectives The aim of this study was to analyze the safety and efficacy of ASCT in CR1 in adults with Ph + ALL. Materials and Methods Adult patients diagnosed with Ph + ALL who underwent ASCT in CR1 after modified ALL-BFM95 protocol from 2015 to 2017 were included. Patients who achieved major molecular response or better were considered for ASCT with cyclophosphamide-total body irradiation regimen and peripheral blood stem cells infused on day 0. Toxicities as per Common Terminology Criteria for Adverse Event v4.0, disease-free survival (DFS), and overall survival (OS) were assessed. Inclusion criteria: Following patients were included—patients aged 18 years and above diagnosed with Ph + ALL; patients receiving BFM-95 induction chemotherapy protocol; patients who achieved CR after induction therapy; nonavailability of human leukocyte antigen match from a matched sibling donor or matched unrelated donor. Exclusion criteria: Patients not willing or unfit for ASCT and patients planned for allogenic hematopoietic stem cell transplantation were excluded. Results Six adult patients with Ph + ALL underwent ASCT in CR1 (median age: 23 [range: 19–36] years, five patients were males [83%]). Imatinib was started at a median of 11 days from the start of induction IA (range: 10–21). Five patients achieved morphological CR after induction 1A and, one patient at the end of induction 1B. The median time to ASCT (from diagnosis) was 8 months (range: 6.4–13). All the six patients had disease relapse and died due to progressive ALL. The median DFS and OS were 19.2 months and 23.3 months, respectively. Conclusion Consolidation ASCT yielded poor outcomes in this study. There was a significant delay from diagnosis to ASCT, which might have impacted the results.
e19519 Background: Gemcitabine, vinorelbine and liposomal doxorubicin (GVD) is an effective regimen in relapsed/refractory Hodgkin’s lymphoma (RRHL). Conventional second-line chemotherapy is still required as the cost of immunotherapy and antibody-drug conjugates are prohibitive to Indian patients. We report the results of a phase II, open-label, single-arm, single centre interventional study in RRHL where dexamethasone replaced liposomal doxorubicin. Methods: Adult patients (≥18 years) with RRHL at first or second relapse were included. GVDex was delivered as outpatient once in 3 weeks (Gemcitabine 1000 mg/m2 IV over 30 min on D1,8; Vinblastine 25 mg/m2 IV fast infusion on D1,8; Dexamethasone 40 mg PO D1-4) for two cycles followed by interim PET CT assessment by Cheson’s criteria and Deauville scoring. The primary endpoint was the objective response rate (ORR = complete response + partial response). The sample size was calculated using Fleming’s 2-stage model (α error: 0.05 and power: 0.8). Twenty patients were required in the first stage. If there were ≥16 responses, the null hypothesis would be rejected and the study stopped. Results: Between May 2016, and December 2020, 26 patients with RRHL were screened, and 20 were enrolled: primary resistant HL-8 patients (40%) and relapsed HL- 12 patients (60%). The median age was 35 years (range:20-52). Six patients (30%) presented with limited stage and 14 patients (70%) with advanced stage HL at relapse. GVdex was delivered as a first salvage regimen in 18 patients (90%) and second in 2 patients. After 2 cycles of GVDex, 16 (80%) had responded [partial response: 12 (60%); complete response: 4 (20%)]. Median number of cycles of GVDex: 3 (range: 1-4). Five patients (25%) required dose reductions due to chemotherapy-related toxicities. The median duration of objective response was 13.4 months. Eleven patients (55%) underwent high-dose chemotherapy supported by autologous stem cell rescue. After a median follow-up of 25 months (95% CI: 5.9-44.5), the median progression-free survival (PFS) was 24.7 months, and the median overall survival (OS) has not been reached. The estimated 2-year PFS was 44%, and the 2-year OS was 79%. The most common treatment-related adverse events were anemia (100%), neutropenia (70%, 14/20) and fatigue (70%, 14/20). Grade 3 or 4 treatment-related AEs occurred in 14 patients (70%). Grade ≥3 neutropenia occurred in 9 patients (45%) and febrile neutropenia in 3 patients (15%). Serious adverse events were reported in 3 patients (15%). One patient developed Ficat and Arlet classification stage III avascular necrosis of the femoral head. One patient died due to suspected COVID-19 pneumonia (non-neutropenic fever) before cycle 2 of chemotherapy. Conclusions: GVDex it is an effective salvage regimen with acceptable toxicity in patients with RRHL. Clinical trial information: CTRI/2017/04/008361.
