Intensive consolidation with G-CSF support: Tolerability, safety, reduced hospitalization, and efficacy in acute myeloid leukemia patients ≥60 years. Am J Hematol 2017; 92:E567-E574. [PMID: 28699225 DOI: 10.1002/ajh.24847] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2017] [Revised: 07/04/2017] [Accepted: 07/06/2017] [Indexed: 11/09/2022]
Abstract
The aim of this study was to evaluate the efficacy and feasibility of intensified consolidation therapy employing fludarabine and ARA-C in cycle 1 and intermediate-dose ARA-C (IDAC) in cycles 2 through 4, in elderly acute myeloid leukemia (AML) patients and to analyze the effects of pegfilgrastim on the duration of neutropenia, overall toxicity, and hospitalization-time during consolidation in these patients. Thirty nine elderly patients with de novo AML (median age 69.9 years) who achieved complete remission (CR) after induction-chemotherapy were analyzed. To examine the effect of pegfilgrastim on neutropenia and hospitalization, we compared cycles 2 and 4 where pegfilgrastim was given routinely from day 6 (IDAC-P) with cycle 3 where pegfilgrastim was only administered in case of severe infections and/or prolonged neutropenia. All four planned cycles were administered in 23/39 patients (59.0%); 5/39 patients (12.8%) received 3 cycles, 3/39 (7.7%) 2 cycles, and 8/39 (20.5%) one consolidation-cycle. The median duration of severe neutropenia was 7 days in cycle 2 (IDAC-P), 11.5 days in cycle 3 (IDAC), and 7.5 days in cycle 4 (IDAC-P) (P < .05). Median overall survival was 1.1 years and differed significantly between patients aged <75 and ≥75 years (P < .05). The probability to be alive after 5 years was 32%. Together, intensified consolidation can be administered in AML patients ≥60, and those who are <75 may benefit from this therapy. Routine administration of pegfilgrastim during consolidation shortens the time of neutropenia and hospitalization in these patients.

Abstract
Acute myeloid leukaemia is a disease of increasing frequency in the elderly. The aim of this study was to describe the survival and the factors influencing survival in a cohort older than 55 years in Northern Ireland, which has a relatively stable population. The median survival of the 92 cases identified in a 6-year period was 18 weeks with an actuarial survival overall at one year of 24%. Independent risk factors for survival were administration of chemotherapy with the intention to induce remission, social class 1 and 2, hepatomegaly, absence of splenomegaly, lower LDH, lower PB blast count, higher haemoglobin, female sex and WHO performance status 0-2. The results of this study suggest that survival from acute leukaemia in the elderly is very poor when an unselected patient cohort is considered.

Abstract
AIMS Acute myeloid leukemia (AML) incidence increases with age, yet treatment of elderly patients has reduced efficacy compared with younger patients and is often poorly tolerated. This retrospective study assessed the outcomes of older patients with AML treated with intensive chemotherapy with or without allogeneic hematopoietic stem cell transplantation (HSCT). METHODS We identified all adult patients≥60 years with newly diagnosed AML treated with induction chemotherapy at our institutions between February 1999 and July 2011. Institutional databases and medical records were used to collect information on baseline characteristics, chemotherapy protocols, response to therapy, relapse-free survival (RFS) and overall survival (OS). RESULTS Three hundred and forty-five patients≥60 years were diagnosed with AML, including 172 patients (49.9%) who received intensive induction chemotherapy. The median age of intensively treated patients was 66 years (range 60-83 years). Responses to one to two cycles of induction chemotherapy were complete remission (CR) in 70.3% of patients, refractory disease in 15.1% and induction death in 14.5%. At a median follow-up of 22 months for survivors, intensive induction chemotherapy resulted in 3-year RFS of 20.2%, and 3-year OS of 24.0%. Seventeen patients (14.0% of patients in CR1) proceeded to allogeneic HSCT in first remission. These patients experienced 3-year RFS of 63.5% and 3-year OS of 77.5%. CONCLUSION Intensive induction chemotherapy for newly diagnosed AML in older patients is feasible and effective in a proportion of patients, and those selected for allogeneic transplantation in CR1 may experience particularly favorable survival outcomes.

Abstract
A retrospective survey of 210 consecutive patients aged ≥ 65 years (median age 69 years, range 65-88 years) with acute myeloid leukemia (AML) diagnosed at a single center over a 6-year period (January 2001 to December 2006) is presented. De novo AML was diagnosed in 179 (85.2 %) patients and 31 (14.7 %) patients had a secondary AML. Twenty-three patients had M0 (11 %), 36 M1 (17.15 %), 57 M2 (27.1 %), eight M3 (3.8 %), 45 M4 (21.4 %), 31 M5 (14.8 %), one M6 (0.5 %), one M7 (0.5 %), and eight patients had unclassified myeloid leukemia (3.8 %) according to French-American-British (FAB) Study Group Classification. Eight patients with M3 (acute promyelocytic leukemia) were excluded from the study. Cytogenetic analysis was performed in 172/202 (85 %) patients. The normal karyotype was found in 81/172 (47 %), high risk aberrations in 32/172 (18.6 %), and favorable karyotype in 13/172 (7.5 %) patients. Supportive and palliative therapies were applied in 115 (56.9 %) patients, a no induction chemotherapy (NIC) group, and 87 (43.1 %) patients received induction chemotherapy (IC group). Complete remission (CR) was achieved in 45/87 (51.7 %) in the IC group and in 5/115 (4.3 %) in the NIC group of patients. After a median follow up of 4 years, 194 (96 %) patients died. The variables significantly associated with a longer overall survival (OS) by univariate analysis were an age of <75 years, a better ECOG performance status (PS) (p = 0.000, CI 95.0 %, 1.358-2.049), a serum LDH activity <600 U/l (p = 0.000, CI 95.0 %, 1.465-2.946), lower white blood cell (WBC) count at diagnosis (p = 0.011, CI 95.0 %, 1.102-2.100), lower comorbidity HCT-CI index (p = 0.000, CI 95 % 2.209-3.458), absence of splenomegaly (p = 0.015, CI 95.0 %, 1.082-2.102) and hepatomegaly (p = 0.008, CI 95.0 %, 1.125-2.171), and no preceding nonhematological malignancy. Multivariate analysis showed that significant factors affecting OS in the IC group were achievement of CR (p = 0.000), the ECOG PS (p = 0.045) and the ECOG PS (p = 0.000), and HCT-CI (p = 0.000) in the NIC group of elderly patients. The present study suggests that a subgroup of elderly patients with both ECOG PS and HCT-CI ≤ 2 at presentation may be eligible for intensive induction chemotherapy.

Abstract
The majority of patients with acute myeloid leukaemia (AML) are elderly. Advancements in supportive care and regimen intensification have resulted in improvements in clinical outcomes for younger AML patients, but analogous improvements in older patients have not been realized. While outcomes are compromised by increased comorbidities and susceptibility to toxicity from therapy, it is now recognized that elderly AML represents a biologically distinct disease that is more aggressive and less responsive to therapy. Some patients tolerate and benefit from intensive remission-induction approaches, while others are best managed with less aggressive strategies. The challenge is to differentiate these groups based on host-related and biological features, in order to maximize the therapeutic benefit and minimize toxicity. As more is understood about the complicated pathogenesis and molecular basis of AML, there are more opportunities to develop and test targeted therapies. Elderly patients, with their narrow therapeutic window, are well positioned to derive a benefit from these novel agents, and therefore, despite a difficult past, there are reasons to be optimistic about the future of elderly AML.

Abstract
BACKGROUNDS AND OBJECTIVES The optimal strategy for the management of elderly patients with acute myeloid leukaemia (AML) is still controversial. We previously reported the effectiveness of low dose cytarabine (Ara-C) and etoposide (VP-16) (AV therapy) for those elderly AML patients ineligible for intensive chemotherapy. We initiated the present feasibility study to improve the efficacy by using glanulocyte-colony stimulating factor (G-CSF) with AV therapy (AVG therapy). PATIENTS AND METHODS The eligibility for enrolment was AML patients according to the World Health Organization (WHO) criteria who were over 60 years of age and who had difficulty in tolerating intensive chemotherapy due to their poor performance status (PS) or some comorbidities. They were given continuous drip infusion of Ara-C (20 mg/body) and VP-16 (50 mg/body) for 7-14 days, and were also simultaneously administered G-CSF (150 microg/m2) once daily. RESULTS The median age of consecutively enrolled 25 patients was 73 years. Eighteen (72%) patients achieved complete remission (CR). The 1-year overall survival (OS) and the 3-year OS rates were 69% and 22%, respectively. The 1-year disease free survival (DFS) rate in CR patients was 44%. The major regimen related toxicities of grade 3 or 4 were only febrile neutropenia in 15 patients (60%). No regimen-related mortality was observed. CONCLUSION AVG therapy was therefore found to be an effective and well-tolerated regimen for remission induction in elderly AML patients with poor PS or comorbidity.

Abstract
High-dose cytosine arabinoside (HiDAC) and intermediate-dose cytosine arabinoside (IDAC) have been introduced as effective and safe consolidation chemotherapy in acute myeloid leukemia, with relatively low rates of life-threatening infections despite the high total dose of the cytostatic drug. To explore the biological background of low toxicity, we examined the numbers, immunophenotype, and functional properties of granulocytes in patients with acute myeloid leukemia receiving HiDAC or IDAC. Interestingly, the absolute numbers of neutrophils remained >500/microl until day 10 in 92 of 125 (74%) HiDAC cycles and in 106 of 113 (94%) IDAC cycles. As assessed by electron microscopy, these day-10 granulocytes surviving chemotherapy were found to be mature cells containing secondary granules and phagolysosomes. They also expressed opsonization- and phagocytosis-linked surface Ags (C3biR, CR1, C1qR, C5aR, FcgammaRI, FcgammaRII, FcgammaRIII, and G-CSF and GM-CSF receptors) like neutrophils in healthy controls. Moreover, these day-10 neutrophils exhibited oxidative burst activity and took up and digested bacteria in the same way as neutrophils in healthy controls. There was a negative correlation between absolute neutrophil counts and severe infections in HiDAC- and IDAC-treated patients with a later onset of infections in IDAC patients (median: IDAC, day 18; HiDAC, day 16). Together, functionally mature neutrophils are detectable at least until day 10 in patients treated with HiDAC or IDAC, and may explain the relatively low hematologic toxicity of these consolidation protocols. IDAC is a superior protocol in this regard and may therefore be most suitable for elderly patients and those at high risk for severe infections.

Abstract
The therapeutic activity and toxicity profile of gemtuzumab ozogamicin were assessed in 40 patients >60 years of age with acute myeloid leukemia (AML) who were not considered eligible for conventional chemotherapy because of advanced age or poor performance status. The drug was administered at the dose of 9 mg/m2 as a single 2-h i.v. infusion on days 1 and 15. Patients who achieved a complete remission (CR/CRp) were to receive a consolidation with two additional injections of the immunotoxin at the same dose. The overall CR/CRp rate was 17% (95% CI, 8-32%). The CR/CRp rate in patients 61-75 years old was 33% (6/18), and 5% (1/22) in patients older than 75 years. Induction death occurred in seven patients (17%), all aged above 75 years. Overall survival was significantly longer in patients aged 61-75 years than in older individuals (P=0.05), and in CD33+ cases than in CD33- cases (P=0.05). We conclude that the dose/schedule of gemtuzumab ozogamicin used in this trial is too toxic in the age group over 75 years. For these patients, additional studies with reduced doses of the immunotoxin are warranted.

Abstract
The role of glycosylated recombinant human granulocyte colony-stimulating factor (G-CSF) in the induction treatment of older adults with acute myeloid leukemia (AML) is still uncertain. In this trial, a total of 722 patients with newly diagnosed AML, median age 68 years, were randomized into 4 treatment arms: (A) no G-CSF; (B) G-CSF during chemotherapy; (C) G-CSF after chemotherapy until day 28 or recovery of polymorphonuclear leukocytes; and (D) G-CSF during and after chemotherapy. The complete remission (CR) rate was 48.9% in group A, 52.2% in group B, 48.3% in group C, and 64.4% in group D. Analysis according to the 2 x 2 factorial design indicated that the CR rate was significantly higher in patients who received G-CSF during chemotherapy (58.3% for groups B + D vs 48.6% for groups A + C; P = .009), whereas no significant difference was observed between groups A + B and C + D (50.6% vs 56.4%, P = .12). In terms of overall survival, no significant differences were observed between the various groups. Patients who received G-CSF after chemotherapy had a shorter time to neutrophil recovery (median, 20 vs 25 days; P < .001) and a shorter hospitalization (mean, 27.2 vs 29.7 days; P < .001). We conclude that although priming with G-CSF can improve the CR rate, the use of G-CSF during and/or after chemotherapy has no effect on the long-term outcome of AML in older patients.

Abstract
BACKGROUND The objectives of the current study were to evaluate the outcome of patients > or = 60 years with acute myeloid leukemia (AML) treated uniformly with high-dose daunorubicin containing induction and modified high-dose cytosine arabinoside containing postremission therapy, and to identify factors predictive of complete disease remission (CR) and survival. METHODS Between 1998 and 2002, the authors treated 117 newly diagnosed patients (acute promyelocytic leukemia excluded) with AML > or = 60 years (median, 67 years; range, 60-82 years). Karyotype (Medical Research Council classification) at diagnosis was categorized as good risk (n = 3), intermediate risk (n = 69), adverse risk (n = 26), and suboptimal/not done (n = 19). A normal karyotype was seen in 41 patients and 40 (34%) had secondary AML. RESULTS The outcome of induction included the following: CR, 62 (53%); early death, 5 (4%); death during hypoplasia, 14 (12%); and resistant disease, 36 (31%). The 3-year event-free (EFS) and overall survival (OS) rates were 9% (95% confidence interval [95% CI], 3-16%) and 17% (95% CI, 9-29%), respectively. In a univariate analysis, cytogenetics, lactate dehydrogenase level, leukocyte count, and performance status were the significant factors for EFS and OS. Age was not a significant prognostic factor for either CR or survival. In a multivariate model, adverse-risk cytogenetics, previous history of myelodysplastic syndrome or antecedent hematologic disorder, and high leukocyte count (> 30 x 10(9)/L) were independent adverse prognostic factors for survival. The impact of adverse karyotype on EFS and OS was time dependent and was observed after 50 and 150 days, respectively. CONCLUSIONS The authors concluded that candidacy for intensive therapy in older patients should be based on biologic features of disease and fitness, rather than on age.

Abstract
The reputation of garlic (Allium sativum) as an effective remedy for tumours extends back to the Egyptian Codex Ebers of 1550 b.c. Several garlic compounds including allicin and its corresponding sulfide inhibit the proliferation and induce apoptosis of several human non-leukaemia malignant cells including breast, bladder, colorectal, hepatic, prostate cancer, lymphoma and skin tumour cell lines. Ajoene (4,5,9-trithiadodeca-1,6,11-triene-9-oxide) is a garlic-derived compound produced most efficiently from pure allicin and has the advantage of a greater chemical stability than allicin. Several clinical trials and in vitro studies of ajoene have demonstrated its best-known anti-thrombosis, anti-microbial and cholesterol lowering activities. Recently, topic application of ajoene has produced significant clinical response in patients with skin basal cell carcinoma. Ajoene was shown to inhibit proliferation and induce apoptosis of several human leukaemia CD34-negative cells including HL-60, U937, HEL and OCIM-1. Also, ajoene induces 30% apoptosis in myeloblasts from chronic myeloid leukaemia patient in blast crisis. More significantly, ajoene profoundly enhanced the apoptotic effect of the two chemotherapeutic drugs: cytarabine and fludarabine in human CD34-positive resistant myeloid leukaemia cells through enhancing their bcl-2 inhibitory and caspase-3 activation activities. The two key anti-leukaemia biological actions of ajoene were the inhibition of proliferation and the induction of apoptosis. Studies have shown the anti-proliferation activity of ajoene to be associated with a block in the G2/M phase of cell cycle in human myeloid leukaemia cells. The apoptosis inducing activity of ajoene is via the mitochondria-dependent caspase cascade through a significant reduction of the anti-apoptotic bcl-2 that results in release of cytochrome c and the activation of caspase-3. Since acute myeloid leukaemia (AML) is a heterogeneous malignant disease in which disease progression at the level of CD34-positive cells has a major impact on resistance to chemotherapy and relapse and the inability to undergo apoptosis is a crucial mechanism of multi-drug resistance in AML patients. The recent findings of the potent enhancing activity of ajoene on chemotherapy-induced apoptosis in CD34-positive resistant human myeloid leukaemia cells suggest a novel promising role for the treatment of refractory and/or relapsed AML patients as well as elderly AML patients. Further studies are warranted to evaluate similar enhancing effect for ajoene in blast cells from AML patients in primary cultures before its introduction in pilot clinical study.

Abstract
PURPOSE High-dose intermittent cytarabine is an effective postremission treatment for patients with acute myeloid leukemia (AML). This regimen is a safe approach in patients < 60 years but produced severe neurotoxicity in the elderly. EXPERIMENTAL DESIGN We have established a dose-reduced age-adapted consolidation using intermediate dose (IDAC; 2 x 1 g/m(2) i.v., days 1, 3, and 5) for AML patients >/= 60 years. Forty-seven de novo AML patients in complete remission (CR; median age, 70 years) were scheduled to receive four consolidation cycles of IDAC. RESULTS In 25 of 47 patients (53%), all four cycles were administered: 9 (19%) received three cycles; 7 (15%) received two cycles; and 6 patients (12%) one cycle. Treatment was well tolerated without neurotoxicity. The median number of days with severe neutropenia (absolute neutrophil count < 500/microl) was 9. Neutropenic fever occurred in 22 of 47 patients (49%) during the first cycle, in 24 of 41 (60%) during the second, in 15 of 34 (44%) during the third, and in 18 of 25 (72%) during the fourth cycle. Only 1 patient died during consolidation (cardiac failure). The median overall survival, disease-free survival, and continuous CR were 10.6, 15.5, and 15.9 months, respectively. The probability of overall survival, disease-free survival, and continuous CR at 5 years were 18, 22, and 30%, respectively. CONCLUSIONS IDAC is a safe and effective postremission therapy for elderly patients with AML.

Abstract
We investigated the prognostic relevance of immunophenotype and other clinical pathological features in 379 adult patients with de novo (acute myeloid leukemia) AML diagnosed and treated at our institution during an 8-year period. Acute promyelocytic leukemia (APL) cases were excluded because they received different treatment. The overall complete remission (CR) rate post-induction therapy with Ara-C and daunorubicin (DNR) was 60% with a median disease free survival (DFS) of 72 weeks, and a median overall survival (OS) of 54 weeks. At diagnosis, CD34, deoxynucleotidyl transferase (TdT), CD7, CD56, HLADR and CD19 were expressed in 65, 19, 32, 15, 87 and 5%, respectively, of 379 evaluable cases. CD34 positive patients had a significantly lower CR rate (P=0.0003) than CD34 negative patients and there was a trend to a lower remission rate in HLADR positive patients (P=0.067). In multi-variate analysis, co-expression of CD34 and HLADR was an independent adverse factor for achieving CR (P=0.0364). CD56 expression was associated with a significantly shorter overall survival (P=0.0262), but did not affect remission rate or disease free survival. Neither TdT nor CD7 expression was associated with treatment outcome. Age (60 years or older) and cytogenetic features (classified by favorable, intermediate and unfavorable groups) were associated with a lower CR rate, shorter disease free survival and shorter OS. Patients with higher white cell counts (WBC) also had a significantly lower remission rate (P=0.0064) and OS (P=0.0127). We propose a prognostic score for achieving CR in AML patients based on age, WBC, cytogenetics and CD34/HLADR status as four independent factors. Defined by number of factors, this score system may help to stratify AML patients to alternative treatment for better outcome.

Abstract
A randomised multicentre study was conducted among patients over 65 yr of age with newly diagnosed acute myeloid leukaemia (AML) to compare oral treatment with etoposide 80 mg/m(2) and thioguanine 100 mg/m(2) twice daily on 5 d and idarubicin 15 mg/m(2) on 3 d (ETI) to a mainly i.v. combination of cytarabine 100 mg/m(2) twice daily on 5 d, idarubicin 12 mg/m(2) x 1, and thioguanine (TAI). Ninety-two patients were enrolled. Their median age was 72 yr, range 65-84 yr. Sixty-five patients had de novo AML, 21 AML subsequent to myelodysplastic syndrome, and six treatment-related AML. They received at first a 6-d i.v. treatment with cytarabine and idarubicin. After the first treatment, 68 patients were randomised to receive two cycles of ETI (n = 36) or TAI (n = 32) and thereafter maintenance with mercaptopurine and methotrexate. Of the 92 patients, 52 (57%) achieved remission at some stage. The median survival was 10 months. There were no significant differences between the patients randomised to ETI or TAI in the remission rate (67% vs. 72%), survival (12 months from randomisation in both arms), event-free survival or relapse rate. The patients randomised to receive ETI spent significantly fewer days at hospital during the two randomised cycles (20 vs. 41 d, P = 0.010), and they had fewer days with infusions, shorter neutropenias and thrombocytopenias and fewer and less severe infections. In conclusion, treatment with oral ETI resulted in a similar antileukaemic effect as obtained with mainly i.v. TAI, with less toxicity and reduced need for hospitalisation.

Abstract
The majority of patients with acute myeloid leukemia (AML) are over 60 years of age at diagnosis. Unlike treatment options for younger adults, those for older patients are limited to non-myeloablative therapy, and many patients are not treatable because of poor performance status. In those who are treatable, long-term survival can be achieved using intensive induction and consolidation chemotherapy. Such curative treatment can be administered in about 70% of elderly patients with AML. In responding patients (up to 60%) the disease-free survival may be almost comparable to that of younger adults. However, treatment-related toxicity results in a higher mortality rate in the elderly patients. Moreover, aggressive chemotherapy cannot be used for 30% of the patients, due to their poor performance status. Currently, palliative cytoreductive treatment and supportive care are considered appropriate for these patients. Recently, however, targeting antileukemic antibodies and inhibitors of signal transduction have been introduced as promising new treatment options. The therapeutic efficiency and toxicity-profiles of these novel drugs are currently under investigation in clinical trials.

Abstract
CD65s appears when the progenitor antigen CD34 disappears, suggesting that this sialylated carbohydrate antigen marks a turning point in normal myeloid differentiation. We characterized acute myeloid leukemia (AML) with low CD65s expression (CD65s(low) AML) in 711 patients entered on seven Eastern Cooperative Oncology Group AML treatment trials (1986-1999). Of those, 198 (28%) qualified as having CD65s(low) AML. Morphologically, CD65s(low) AML was more common in FAB subgroups with minimal differentiation, M0/M1 (P=<0.0001). Early precursor antigens CD34, CD117 and terminal transferase were more frequent in CD65s(low) than CD65s(high) AML (P=<0.0001). Myeloperoxidase was present in fewer CD65s(low) myeloblasts, and the more mature myeloid antigens, CD15 and CD11b, were rarely detected (P=<0.0001). Yet, the two diagnoses did not differ in the distribution of cytogenetic prognostic groups or the occurrence of the multidrug-resistance mediator, P-glycoprotein. CD65s(low) AML patients were significantly older than CD65s(high) cases (P<0.0001). Furthermore, the incidence of CD65s(low) cases increased with age, from 20% in patients under the age of 50 years to 67% in patients older than 80 years (P<0.0001). Overall, complete remission (CR) rate and overall survival were comparable in CD65s(low) and CD65s(high) AML. However, among patients >55 years of age, CD65s(low) AML had a decreased CR rate of 33 vs 44% in CD65s(high) AML (P=0.055). Thus, CD65s(low) AML represents immunophenotypically undifferentiated disease and occurs predominantly in older adults. Although not statistically significant, the observed association between low CD65s expression and decreased CR rate only in patients over the age of 55 is intriguing.

Abstract
We retrospectively analyzed 126 acute myelogenous leukemia (AML) patients aged > or =60 years who had all been referred to the same hematological department between 1989 and 1999. In 76 de novo AML cases, 53 patients (median age, 72 years) were treated with combination chemotherapy (CT) for remission induction. Complete remission (CR) rate was 57.1%. The median overall survival (OS) was 16 months, and the rate of 3-year OS was 28%. The favorable prognostic factors were performance status < or =2, cholinesterase > or =100 IU, and intermediate or favorable karyotype (P < .01). Seventeen patients (median age, 78 years) with hypocellular bone marrow or poor general condition were treated with low-dose cytosine arabinoside (LDAraC). In these patients, the CR rate was 50% and the median OS was 11 months, with an OS estimate at 3 years of 14%. All patients with hypocellular bone marrow who received LDAraC for 21 days achieved CR. In 50 patients who developed AML following a myelodysplastic syndrome (MDS/AML), 22 patients (median age, 74 years) were treated with CT, and 14 (median age, 74 years) patients were treated with LDAraC. The CR rates were 22.7% and 21.4%, respectively, and the median OS durations were 8 months and 11 months, respectively. There were no significant factors that would indicate a good prognosis in MDS/AML patients.

Abstract
Age represents one of the most important adverse prognostic factors in acute myeloid leukemia (AML). The therapeutic results for patients older than 60 years accrued into clinical trials of intensive chemotherapy are largely unsatisfactory (complete remission rates rarely superior to 50-60%; median relapse-free survival usually less than 12 months). Because only 30-40% of elderly patients are actually entered into these trials, the overall failure of current treatments appear even more disappointing when considered in the context of the whole population of older individuals with AML. This appears primarily due to intrinsic differences in the biology of leukemia itself and to host-related factors (i.e. reduced tolerance to chemotherapy and comorbidity). AMLs of older subjects display several biological overlaps with secondary AMLs including multilineage involvement, phenotype, unfavorable cytogenetics and elevated activity of multidrug resistance genes. The clinical application of biologically-based prognostic factors may enable to separate patients who may actually benefit from aggressive chemotherapy from those who should be offered attenuated/palliative treatments or enrolled upfront into experimental trials of new drugs or biologic/immunologic treatments. This may hopefully result in a 'risk-adapted' strategy aimed at improving disease free survival and/or quality of life for patients with differing risk profiles.

Abstract
A retrospective analysis was performed on 263 consecutive patients aged over 60 with de novo acute myeloid leukemia (AML) diagnosed in a single institution between 1979 and 1998. Eighty-nine patients (33%) received only palliative treatment, while 174 patients (67%) were treated with different intensive chemotherapy regimens. The 5- and 10-year overall survival (OS) for the whole series was 7.7+/-1.2 and 4.3+/-1.6%, respectively. For patients receiving chemotherapy, OS was 10.5+/-2.5 and 7+/-2.6%, while for those patients receiving supportive treatment it was 1.1+/-1.1 and 0%, respectively (P=0.002). Within the group of patients receiving chemotherapy, the complete remission (CR) rate was 46%; treatment failure rate was 54% (36% due to treatment-related mortality and 18% due to resistant disease). Variables influencing CR rate were FAB subtype, CD7 positivity, chemotherapy regimen, creatinine level, hepatomegaly, and period of diagnosis. Median disease-free survival (DFS) duration was 8.4 months with a probability of being disease-free at 10 years of 10+/-5%. There were no significant differences in DFS according to age. According to the period of diagnosis (1979-1986 vs. 1987-1998), improvements in the CR rate (27 vs. 56%, P=0.0002), and OS (10.9 vs. 15.7 months, P=0.0007) were observed. This large single-center study of unselected de novo AML elderly patients substantiates the progressive improvement achieved in the management of elderly patients with AML, probably due to an improvement in supportive care and the administration of conventional induction chemotherapy.

Abstract
AbstractIn acute myeloid leukemia (AML) patients, a variety of clinical and biologic parameters, including phenotype, have been examined for potential value in predicting treatment response and survival. The European Group for the Immunological Classification of Leukaemias (EGIL) has proposed that AML be defined immunologically by the expression of 2 or more of the following myeloid markers: myeloperoxidase, CD13, CD33, CDw65, and CD117. With regard to this classification, the prognostic significance of 21 antigens taken separately and with immunophenotypic subgroups were evaluated and compared with other clinical and biological variables in 177 adult AML patients. None of the antigens tested were associated with treatment outcome. In contrast, patients with blasts disclosing a full expression of panmyeloid phenotype (defined by the expression of all 5 myeloid markers) had a higher complete remission rate (P < .0001) and differed significantly in disease-free survival (P = .02) and overall survival (P = .008) than patients whose cells expressed fewer than 5 of these markers. In multivariate analysis, only age, panmyeloid phenotype, performance status, and permeability glycoprotein activity influence treatment outcome. Cytogenetics was significant in univariate analysis but not in multivariate analysis, most likely because of the redundancy with panmyeloid phenotype and a higher sensitivity of immunophenotyping. Patients whose cells exhibit the panmyeloid phenotype appear to define a relatively homogeneous biological subset of AML. The 4 independent prognostic factors were used to create a prognostic score, defined by the number of factors present. This score permitted a stratification of patients with AML, thereby allowing for the consideration of innovative therapies to improve outcome in the poorer outcome groups.

Abstract
A consecutive population-based series of 372 adult acute myeloid leukemias, successfully cytogenetically investigated at a single center between 1976 and 1993, is reported. All medical records were reviewed in order to ascertain the prognostic impact of karyotype, divided into three groups; favorable (t(8;21), t(15;17), and inv(16) irrespective of karyotypic complexity; n = 40), poor (der(1;7), inv(3), -5, del(5q), -7, t(9;22), and complex karyotypes including whole or partial losses of chromosomes 5 and/or 7; n = 56), and intermediate (other abnormalities or normal karyotype; n = 276). The possible modification by age, gender, time period, morphologic subtype, and bone marrow transplantation (BMT) on this prognostic impact was also determined. The chemotherapy regimens used were heterogeneous over time but principally the same at any given point in time. The majority of the patients were treated with combinations including an anthracycline and cytarabine with curative intent. Gender, morphology, and BMT did not significantly modify the effect of cytogenetic patterns on survival time, whereas age and time period did. The hazard ratios for the subgroups favorable, intermediate, and poor were 1.0, 1.2 and 1.9 at age 20-49; 1.0, 2.5 and 4.5 at age 50-64; 1.0, 4.1 and 11.4 at age 65-74; 1.0, 1.4 and 2.2 for the time period 1976-1987 and 1.0, 2.0 and 6.7 for 1988-1993. The salient feature of the Kaplan-Meier curves was the improved survival during the later time period for patients with favorable and intermediate cytogenetic abnormalities. The present findings thus suggest that it is mainly these patient groups that have benefited from advances in therapy, including supportive care.

Abstract
Effective treatment of the elderly patient with AML remains a challenging task. Acute myelogenous leukemia is clearly a different disease in the elderly than in the young, for many reasons, both clinical and biologic, which contribute to the worse prognosis in the elderly. The elderly, as a group, have been underrepresented in clinical trials. Several important prognostic variables have been identified and described, however, that can help the physician select the appropriate treatment for any individual patient. Age itself should not preclude an attempt at therapy, especially for AML, which progresses very rapidly in the absence of treatment. After careful analysis of prognostic factors, in any individual patient, however, the outlook may be so poor that it may be desirable to withhold treatment. With a better understanding of the pathophysiology of AML in the elderly, more targeted and less toxic treatment regimens will become available. At present, however, clinicians must use an improved understanding of the disease to predict its behavior in an individual patient, so that the currently available treatment modalities are used most prudently.

Abstract
We describe a case of acute myeloid leukemia in a 2 1/2-year-old boy presenting with a mediastinal tumor causing respiratory distress, and lymph node enlargement in the cervical and inguinal regions. Apart from myeloid markers CD13 and CD33, blast cells also expressed stem cell marker CD34 and megakaryocytic marker CD61. Cytogenetically, inv(7)(p21q31) was found in 9/25 and 15/25 analyzed metaphases from short-term cultures of lymph node and bone marrow cells, respectively. The patient is in continued complete remission 26 months post diagnosis. The case demonstrates that chromosome aberrations other than inv(16), t(8;21), and t(9;11) may be associated with extramedullary disease, and that not all chromosome 7 aberrations are prognostic adverse findings.

Abstract
As the geriatric population is growing, it is increasingly important to be familiar with chemotherapy for the elderly. Age-related changes in pharmacokinetics are documented for doxorubicin, etoposide, ifosfamide, daunorubicin, mitomycin, cisplatin and methotrexate. The hematological toxicity of most standard-dose chemotherapy is not affected by age in patients with normal organic functions and good performance status, although increased toxicity with aging is suggested in the use of actinomycin-D, etoposide, vinblastin, methotrexate, methyl-CCNU, doxorubicin and mitomycin, and in dose-intensive chemotherapy. Among non-hematological toxicities, only doxorubicin-induced cardiomyopathy and bleomycin-induced pulmonary toxicity are demonstrated to be accelerated in the elderly. There is no evidence that advanced age decreases the efficacy of chemotherapy for tumors, except for Hodgkin's disease and acute leukemia. These results suggest that advanced chronological age alone is not always associated with severe toxicity and poor prognosis, and that many elderly patients with cancer will benefit from chemotherapy. To answer questions regarding the optimal chemotherapy regimen, dose and intensity in this population, the influence of age should be analyzed in a multivariate approach in future studies.

Abstract
The majority of patients with cancer in the United States are more than 70 years old. Despite the increased understanding of the molecular bases for both oncogenesis and aging, the overlap of cancer and aging at that level remains a wide-open research domain. Similarly, at the clinical level, there is also an increased awareness of the need for more information about the influence of host age on the development of tumors, on the growth and spread of the disease, and on treatment expectations. In this review, we have attempted to frame questions regarding cancer and aging from the perspective of biogerontology and geriatric medicine. An increased effort to address the issues of aging is of paramount importance at all levels of cancer investigation.
