Jumping translocations of 1q refer to the break-off of chromosome 1q as a donor fusing to two or more recipient chromosomes. We detected jumping translocations of 1q in three patients with initial diagnosis of myelodysplastic syndrome (MDS) and later progression to acute myeloid leukemia (AML). Review of literature found jumping translocations of 1q in 30 reported cases of MDS and AML. The cytogenetic findings from these 33 cases showed that seven cases had a stemline clone and 26 cases had de novo jumping translocations of 1q in which 5% of cell lineages had additional structural rearrangements. In 75% of cases, the 1q donor jumped to the short arm of recipient acrocentric chromosomes. Approximately 82% of the fusions occurred in the telomeric regions of short and long arms and 18% occurred in the pericentric or interstitial regions of recipient chromosomes. Hypomethylation of the donor 1q pericentromeric region and shortened telomeres in recipient chromosomes were associated with the formation of jumping translocations. Jumping translocations of 1q as an indication of chromosomal instability pose high risk for progression of MDS to AML and a poor prognosis. Further understanding of underlying genomic defects and their clinical significance will improve overall treatment and patient care.

Abstract Optimal management of patients with acute myeloid leukemia requires an accurate diagnosis along with cytogenetics and an intensive systemic chemotherapy regimen administered by a multidisciplinary team of experienced physicians, nurses and other support staff. It has been suggested that such complex patients should be treated only at tertiary care centers. However, it is often difficult for patients and families to receive care at teratiary care center which may be at a great distance from their home. Here we present a retrospective review of all patients diagnosed and treated for acute myeloid leukemia at William W Backus Hospital, a 213 bed acute care hospital serving a community of 70,000 in Norwich, Connecticut between the years 2000 and 2005. A total of 44 patients were treated during this period. There were 22 males and 22 females. The median age was 67.5 years. Bone Marrow samples were evaluated by a hematopathologist (histopathology, flowcytometry and cytogenetics) at a near-by tertiary care center. FAB subgroups and cytogenetics were similar to other published studies. APML patients are not included in this analysis. The median survival for the entire group was 14.7 months ranging from 2 days to 113 months. Fourteen patients were alive, all in continued clinical remission except one with relapsed disease and one patient remains transfusion dependent. Median survival was 15.2 months for men compared to 13.2 months for women. Four patients were referred for bone marrow/stem cell transplant after induction therapy. The limitation of this study is the relatively small number of patients as one would expect from a study done at a small community hospital. Nevertheless, it appears that the median survival of our patients is similar to a pooled analysis of five SWOG trials published by Gundacker et al. We conclude that most patients with acute myeloid leukemia can be managed in a community hospital with commitment and experience to treat such patients.

PURPOSE Infections remain a major challenge in the treatment of acute myeloid leukemia (AML). Induction-related mortality reported in the literature is approximately < 5% in clinical trials. However, the real-world scenario is different, especially in developing countries, given the high incidence of multidrug-resistant (MDR) organisms, high incidence of fungal pneumonia at baseline, and significant delay before initiation of chemotherapy. We aimed to look at contemporary infections and infection-related mortality and analyze the patterns of infections. MATERIALS AND METHODS This retrospective study was conducted at a large tertiary care oncology center in India. Patients with newly diagnosed AML who were older than age 15 years, considered fit for intensive therapy, and treated in the general wards of the adult hematolymphoid unit from March 1, 2014, until December 31, 2015, were included. RESULTS One hundred twenty-one patients were treated during the study period. The most common presenting complaint was fever (85%). The focus of infection at presentation was found in 63% of patients, with respiratory infection being the most common (47%). MDR organisms were isolated in 55% of patients during induction from various foci. Klebsiella pneumoniae was the most common blood culture isolate (42.9%). Fungal pneumonia was diagnosed in 55% of patients during induction despite antifungal prophylaxis. Treatment-related mortality was 10.7% in all phases, with an induction mortality rate of 7.4%. Complete remission was attained in 69% of patients. Of all patients who received induction chemotherapy, 74% completed all three consolidation cycles. The 121 patients were followed up for a median period of 53 months. Four-year event-free survival was 35.8%, and 4-year overall survival was 41.5%. CONCLUSION Infections and infection-related mortality are major challenges during AML induction. Gram-negative MDR and fungal infections are particularly common in our region.

Abstract Introduction: Patients with acute myeloid leukemia (AML) characterized by FMS-like tyrosine kinase-3 (FLT-3) internal tandem duplication (ITD) mutations have poor outcomes, especially in the relapsed setting. Although small molecule inhibitors of FLT-3 have been explored for these patients, many inhibitors have demonstrated limited single-agent efficacy with short response durations. Sorafenib, a multi-kinase inhibitor with activity against FLT-3, has previously been evaluated alone and in combination with induction chemotherapy or azacytidine in AML patients. Here we describe our experience with the combination of the DNA hypomethylating agent, decitabine (D), and sorafenib (S) for the treatment of FLT-3 ITD mutant AML. Methods: We retrospectively reviewed records of patients with FLT-3 ITD mutant AML who were treated off protocol with decitabine and sorafenib from 2011-present. Descriptive statistics, treatment response, and overall survival were recorded. Results: A total of six patients were identified. Mean age was 56 (range 34-70) years. Two-thirds (4/6) were female. All patients were confirmed to have recurrence of de novo AML characterized by FLT-3 ITD mutations prior to therapy. Patients received at least 1-2 cycles of concurrent decitabine 20 mg/m2 for 10 days and sorafenib 200-400 mg twice a day for 28 days. Five patients had relapsed/refractory AML (RR-AML) following 1-3 prior therapies. One patient had de novo AML in complete remission with incomplete count recovery (CRi) and received DS as consolidation. The overall response rate was 83%. Eighty percent (4/5) of patients with RR-AML attained CRi. One patient receiving DS consolidation attained complete remission (CR). Two patients received subsequent allogeneic stem cell transplantation with one individual still alive after 348 days. FLT3 ITD allelic ratio (available on 3 patients) decreased after DS therapy and correlated with CRi. Median overall survival was 111 days (range 59-348) from the initiation of DS to death from any cause or last known follow-up. Two patients developed treatment-related neutropenic fever/sepsis and elevated liver enzymes, respectively, which did not require dose adjustment. One patient developed heart failure of uncertain etiology. Conclusions: In this single institute case series, we demonstrated that the combination of decitabine (10 days) and sorafenib was well tolerated, resulted in high CR/CRi rates (80%), and prolonged overall survival in patients with heavily pretreated relapsed/refractory FLT-3 ITD mutant AML. Further investigation of this regimen in clinical trials is warranted.
