Role of ALK Inhibitors in Anaplastic Large Cell Lymphoma-Experience from an Indian Center.

Perumal Kalaiyarasi JayachandranAnaplastic large cell lymphoma (ALCL) is the second most common type of peripheral T cell lymphoma and an aggressive mature T cell lymphoma. About 50 to 70% of systemic ALCLs are anaplastic lymphoma kinase positive (ALK +), the proportion even higher in the pediatric population. The 5-year survival after chemotherapy is around 70 to 80%. But there is a subgroup of ALK+ ALCL patients who are refractory to chemotherapy. Brentuximab vedotin is an approved agent for such patients. The activity of ALK inhibitors in ALK+ non-small cell lung cancer is well known and has been approved for use. The efficacy and safety of ALK inhibitors in ALK + ALCL are largely under-reported. Here we have reported our experience in the use of ALK inhibitors in relapsed refractory ALK+ ALCL.

Autologous Stem Cell Transplantation in Testicular Germ Cell Tumor-Preliminary Experience from a Single Center.

Background Germ cell tumor (GCT) of the testis is one of the highly curable solid organ malignancies. Those who experience relapse after platinum-based chemotherapy can be salvaged with systemic therapy followed by high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT). Complete remission can be obtained in approximately 50 to 60% of patients treated with HDCT. Our experience reports the efficacy and safety of HDCT followed by ASCT in relapsed GCT. Methods Analysis of patient records (2012-2019) showed that three patients had received HDCT and ASCT. Results All the three patients were treated with BEP (bleomycin, etoposide, and cisplatin) as first-line therapy. HDCT was done in Case 1 after third-line salvage and in other two patients after second-line salvage chemotherapies. High-dose carboplatin and etoposide were used as conditioning regimen. Granulocyte colony-stimulating factor was used for the mobilization of stem cells. After ASCT, complete remission was documented in all the patients. All were alive and disease-free till the last follow-up. Grade ¾ toxicities including myelosuppression, diarrhea, and mucositis were observed in all three patients. Conclusion This is the first report from India on HDCT with ASCT in GCT. HDCT/ASCT seems to be feasible, safe, and effective in relapsed testicular GCTs.

Haploidentical Hematopoietic Stem Cell Transplantation in Leukemia's: Experience from a Cancer Center in India.

There has been a surge in haploidentical hematopoietic stem cell transplantation (HSCT) in India recently. However, there is a paucity of data on haploidentical HSCT from India. The report is an analysis of data of haploidentical HSCT performed at our center. Analysis of patients with acute leukemia or chronic myeloid leukemia who underwent haploidentical HSCT during 2014-2019 was performed. The graft versus host disease (GVHD) prophylaxis was post-transplant Cyclophosphamide with Mycophenolate-mofetil and Cyclosporine. All patients were transfused peripheral blood stem cells from donors. Overall survival (OS) was calculated using the Kaplan-Meier method. Twenty-one patients underwent haploidentical HSCT. Fourteen-patients were males. The median age of patients was 15 years. Fludarabine with total body irradiation was the most common conditioning regimen (n = 15, 71.4%). The median duration for neutrophil and platelet engraftment was 14 days. Cumulative incidence of acute and chronic GVHD was 19%, and 38% respectively. The median follow-up was 26 months and the two-year OS was 38%. Twelve (57%) patients died during the study period, 8 patients (38%) died from transplant-related mortality (TRM), and 4 from disease relapse. Sepsis was the cause of death in six of the eight TRM. Nine out of 21 patients (42.8%) are leukemia-free on follow-up. Haploidentical HSCT is a promising modality of treatment in patients who have no suitable matched donors. Though the TRM remains high, good disease control was achieved in 42.8% of patients. Multi-drug resistant bacterial infection remains a challenge in performing haploidentical HSCT in developing countries.

COVID19 in children with cancer in low- and middle-income countries: Experience from a cancer center in Chennai, India.

Crowded outpatient clinics and common wards in many hospitals in low and middle-income countries predispose children, caregivers, and health care workers to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report on the clinical features and outcomes of 15 children with cancer at our center who tested positive for SARS-CoV-2. Five out of 15 patients were symptomatic, and one patient required intensive care and respiratory support. All the patients in the study have recovered from the SARS-CoV-2 infection without any sequelae and have resumed their cancer treatment.

Plasmablastic lymphoma - single centre experience with infusional EPOCH chemotherapy.

BACKGROUND: Plasmablastic lymphoma (PBL) is a rare type of aggressive large B - cell non-Hodgkin Lymphoma (NHL) which was initially described in HIV positive individuals and later was also described in immune-competent individuals. It was included as a distinct entity in the WHO lymphoma classification in 2008. METHODS: The clinical features, HIV status, treatment details, and outcomes of patients diagnosed with plasmablastic lymphoma from January 2012 to December 2018 were retrospectively collected from the patient records and analyzed. The survival analysis was done by Kaplan Meier analysis and the comparison was done by the Log Rank test. RESULTS: The median age of 25 patients, included in the study was 41 years (Range 13-71 years). Males constituted 76 %. HIV positivity was 72 %. Stage IV disease was present in 76 %. Extranodal involvement was seen in 96 %. Out of 25 patients, seven did not receive any treatment and three received metronomic oral chemotherapy due to poor performance status at presentation. Fifteen patients received chemotherapy on a curative intent. Infusional EPOCH chemotherapy was given in 13 patients. CHOP and CHOEP chemotherapy was given in one patient each. The median number of cycles was 6 (Range: 3-8). The overall response rate of patients treated on a curative intent was 80 % (Complete response and partial response in 8 and 4 respectively). Three patients underwent high dose chemotherapy with autologous stem cell rescue at first remission. The median event-free survival (EFS) and median overall survival (OS) of the whole study population was 5.9 and 12.4 months respectively, with a median follow of 26.9 months. The median EFS was 13.8 months and the median OS was not reached in the curative-intent group. The factors adversely influencing the EFS and OS were Age > 40 years, high IPI, and non-curative intent of treatment. CONCLUSION: Plasmablastic lymphoma commonly presents as stage 4 disease with extranodal involvement and is more common in immune-deficient individuals. Infusional EPOCH chemotherapy is a promising option that induces long term remission.

Olanzapine versus metoclopramide for the treatment of breakthrough chemotherapy-induced vomiting in children: An open-label, randomized phase 3 trial.

BACKGROUND: Breakthrough chemotherapy-induced vomiting (CIV) is defined as CIV occurring after adequate antiemetic prophylaxis. Olanzapine and metoclopramide are two drugs recommended for the treatment of breakthrough CIV in children, without adequate evidence. We conducted an open-label, single-center, phase 3 randomized controlled trial comparing the safety and efficacy of olanzapine and metoclopramide for treating breakthrough CIV. PROCEDURE: Children aged 5-18 years who developed breakthrough CIV after receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy were randomly assigned to the metoclopramide or olanzapine arm. The primary objective of the study was to compare the complete response (CR) rates between patients receiving olanzapine or metoclopramide for treating breakthrough CIV during 72 hours after the administration of the study drug. Secondary objectives were to compare CR rates for nausea and toxicities between the two arms. RESULTS: Eighty patients were analyzed (39 in the olanzapine arm and 41 in the metoclopramide arm). CR rates were significantly higher in the olanzapine arm compared with the metoclopramide arm for vomiting (72% vs 39%, P = 0.003) and nausea (59% vs 34%, P = 0.026). Seven patients in the metoclopramide arm crossed over to the olanzapine arm and none crossed over in the olanzapine arm (P < 0.001). The mean nausea score in the olanzapine arm was significantly lower than the metoclopramide arm after the initiation of the rescue antiemetic (P = 0.01). Hyperglycemia and drowsiness were more commonly seen in the olanzapine arm. CONCLUSION: Olanzapine is superior to metoclopramide for the treatment of breakthrough CIV in children. Drowsiness and hyperglycemia need to be monitored closely in children receiving olanzapine for breakthrough CIV.
