We review here the state of the art of diagnosis and treatment of AML and provide insights into the emerging novel biomarkers and therapeutic agents that are anticipated to be useful for the implementation of personalized medicine in AML.
Lung cancer is a global problem fueled by the continuous use of tobacco in most countries, despite efforts at expanding smoking cessation programs. Several advances in the diagnosis and treatment of lung cancer were achieved in the past decade. This progress notwithstanding, most lung cancer patients succumb to their illness, and few enjoy long-term survival.
Quan and colleagues have providedan important and timelyreview on the treatment ofbrain metastases in patients with smallcell lung cancer (SCLC). We certainlyagree with the comments and viewsof the authors, but wish to emphasizeseveral aspects of central nervoussystem (CNS) metastases in SCLCpatients.
Much excitement has beengenerated in the past fewyears around the potential of“omics technologies” to produce advancesin medicine. For example, globalprofiling using DNA microarrayshas uncovered patterns of gene expressionthat may have clinical utility. However,it has become clear that numerousobstacles must be overcome beforefindings from these studies have a substantialimpact on clinical practice.
Lung cancer is the leading cause of cancer mortality in the United States. A significant number of patients present with disease involving mediastinal lymph nodes. As survival after surgery alone for stage III disease is poor, radiation therapy and chemotherapy have been evaluated in the neoadjuvant and adjuvant settings to improve outcomes. The benefit of adjuvant chemotherapy in the subgroup of patients with N2 disease is uncertain. Small randomized trials enrolling patients with stage III disease have shown a benefit of neoadjuvant chemotherapy over surgery alone. Whether neoadjuvant chemotherapy is superior to adjuvant chemotherapy is under investigation. Furthermore, whether neoadjuvant chemoradiotherapy is superior to neoadjuvant chemotherapy is controversial, and few randomized studies comparing these approaches have been reported. Nevertheless, neoadjuvant chemoradiotherapy appears to be associated with higher rates of resection, higher rates of clearance of mediastinal nodal disease, and better local/regional control. The use of postoperative radiation therapy (PORT) has declined since the publication of the 1998 meta-analysis suggested a detriment in survival with this strategy. However, radiation techniques are improving and emerging data support the use of carefully delivered PORT. Finally, it remains unclear whether surgical resection offers an advantage over definitive chemoradiotherapy alone for stage III disease. In summary, locally advanced NSCLC remains a formidable challenge with few cures, and optimal treatment requires the careful use of surgery, chemotherapy, and radiation therapy.
Our aims in this article are to describe the various imaging sequences that comprise the multiparametric MRI exam, as well as to review current literature on the strengths/weaknesses of these sequences; to delineate strategies for standardizing interpretation and reporting of MRI results; and to expound on the role of prostate MRI in clinical practice.
A 37-year-old Lebanese male with no significant past medical history initially presented with an increase in abdominal girth over a few weeks with worsening shortness of breath, nausea, and intermittent vomiting.
In this paper, we review the use of serum tumor markers in risk assignment and response evaluation; the treatment of previously untreated and relapsing patients; the role of surgical resection of residual disease, including retroperitoneal node dissection; and the importance of clinical trials for addressing unanswered questions and testing new therapies.
In 1970, Ansfield and colleagues published the results of a randomized trial in head and neck cancer, which showed that giving fluorouracil (5-FU) concomitantly with radiation decreased regional recurrences and improved overall survival over radiation alone.[1] Publication of these results came 6 years before those of an Italian trial showing similar findings with adjuvant cyclophosphamide, methotrexate, and 5-FU (CMF) in breast cancer.[2] Yet, while adjuvant chemotherapy has rapidly become the norm in the management of early breast cancer, concomitant chemotherapy is still considered undefined in the treatment of head and neck cancer. This situation is elegantly described by Dr. Karen Fu, one of the most respected investigators in this area.
Michael H. Levy, MD: This 38-year-old white male first came to his physician in January of 1993 complaining of epigastric and low back pain. In March of 1993, he was diagnosed with pancreatic cancer that was metastatic to his
Unresectable pancreatic cancer has few therapeutic options and adismal prognosis. Cyclooxygenase-2 (COX-2) expression is increasedat the RNA and protein levels in most human pancreatic cancers. Thepurpose of this trial was to determine whether the addition of a COX-2inhibitor to chemotherapy was beneficial. To date, 11 patients with inoperablepancreatic cancer have been treated with the combination ofgemcitabine (Gemzar), irinotecan (Camptosar), and celecoxib(Celebrex) at 400 mg orally twice daily. Encouraging pain relief, improvementin performance status, and decreases in CA 19-9 andcarcinoembryonic antigen levels have been observed.
This year's American Society of Clinical Oncology meeting featured a highly select lineup of sessions dealing with hematologic malignancies.
This video examines findings from the International Breast Cancer Intervention Study (IBIS-1), which found that patients with menopause symptoms were less likely to continue long-term tamoxifen therapy.
In this article, we provide an overview of the currently available systemic agents, including immunotherapeutic agents and targeted tyrosine kinase inhibitors. We also provide a practical management algorithm to guide the practicing oncologist in the use of both of these new therapies and the more traditional local treatments.
The treatment of inoperable stage III non–small-cell lung cancer (NSCLC) remains a challenge due to high rates of distant metastasis, local recurrence, and toxicity associated with definitive therapy.

An estimated 14,600 new cases of multiple myeloma will be diagnosed in the United States in 2002. Multiple myeloma remains an incurable disease despite significant improvements in complete response rates and overall
Significant advances have been made in the treatment of advancedcolorectal cancer over the past 5 years, namely due to the introductionof three novel cytotoxic agents-capecitabine (Xeloda), irinotecan(Camptosar), and oxaliplatin (Eloxatin)-and the recent approval oftwo biologic agents-bevacizumab (Avastin) and cetuximab (Erbitux).During this time period, the median survival of patients with advanced,metastatic disease has gone from 10 to 12 months to nearly 24 months.Intense efforts have focused on identifying novel targeted therapies thattarget specific growth factor receptors, critical signal transduction pathways,and/or key pathways that mediate the process of angiogenesis.Recent clinical trial results suggest that the anti-VEGF antibodybevacizumab can be safely and effectively used in combination witheach of the active anticancer agents used in colorectal cancer. Despitethe development of active combination regimens, significant improvementsin the actual cure rate have not yet been achieved. Combinationregimens with activity in advanced disease are being evaluated in theadjuvant and neoadjuvant settings. The goal is to integrate these targetedstrategies into standard chemotherapy regimens so as to advancethe therapeutic options for the treatment of advanced colorectal cancer.Finally, intense efforts are attempting to identify the critical molecularbiomarkers that can be used to predict for either clinicalresponse to chemotherapy and/or targeted therapies and/or the drugspecificside effects. The goal of such studies is to facilitate the evolutionof empiric chemotherapy to individually tailored treatments forpatients with colorectal cancer.
Franklin, Delengowski, and Yeo have made a strong case for the importance of cancer rehabilitation.
This article provides an overview of the current state of knowledge pertaining to exercise modulation of the inflammation-immune axis in cancer. The current evidence suggests that exercise may be a promising adjunctive strategy that can favorably alter numerous components of the immune system, which, in turn, may modulate tumorigenesis.
Hypothyroidism is a common and potentially serious endocrine disorder in the general population.
Hodgkin lymphoma (HL) is one of the most curable malignancies in adults. However, survival rates for elderly patients with HL (often defined as ≥ 60 years of age) are inferior to those achieved by younger populations.
The leukemias and lymphomas represent a group of heterogeneous myeloid or lymphoid clonal stem cell disorders with variable clinical presentation, pathological characteristics, prognosis and recommendations for treatment.[1]
Cytokines have been used in the treatment of patients with cutaneousmelanoma. Granulocyte-macrophage colony-stimulating factor(GM-CSF, sargramostim [Leukine]) leads to dendritic cell/macrophagepriming and activation, and also increases interleukin-2 (IL-2)receptor expression on T lymphocytes. IL-2 creates lymphokineactivatedkiller cells and tumor-infiltrating lymphocyte cells. In thisopen-label, single-arm study of 16 high-risk patients, we combined thesetwo agents to take advantage of their different but complementary functions.All patients underwent potentially curative surgery. Postoperatively,each patient received GM-CSF at 125 μg/m2/d subcutaneously(SC) for 14 days; this was followed by IL-2 at 9 million IU/m2/d SC for4 days, and then 10 to 12 days of no treatment. In addition, patientswho had large tumors that could yield over 100 million live tumor cellsreceived autologous melanoma vaccines. The duration of follow-upranged from 21 to 42 months (median: 27 months). During follow-up,five patients developed metastases. This program was carried out on anoutpatient basis, and no hospitalization was required. It was well toleratedwith minimal side effects. The combination treatment regimen ofGM-CSF and IL-2 with or without autologous vaccine used adjuvantlyappears to benefit high-risk melanoma patients; further clinical testingof this regimen is warranted.
At this point, there is expectation that pertuzumab given in the neoadjuvant setting will improve long-term efficacy. We welcome the opportunity to include pertuzumab in the neoadjuvant regimen of patients with HER2-positive breast cancer.
Vaccines are a promising but still experimental treatment for melanoma.They are intended to stimulate immune responses against melanomaand by so doing, increase resistance against and slow the progressionof this cancer. Key requirements for vaccines to be effectiveare that they contain antigens that can stimulate tumor-protective immuneresponses and that some of these antigens are present on thetumor to be treated. Unfortunately, these antigens are still not known.To circumvent this problem, polyvalent vaccines can be constructedcontaining a broad array of melanoma-associated antigens. Severalstrategies are available to construct such polyvalent vaccines; each hasadvantages and disadvantages. Clinical trials have shown that vaccinesare safe to use and have much less toxicity than current therapy formelanoma. Vaccines can stimulate both antibody and T-cell responsesagainst melanoma, with the type of response induced, its frequency,and its magnitude depending on the vaccine and the adjuvant agentused. A growing body of evidence suggests that vaccines can be clinicallyeffective. This evidence includes correlations between vaccineinducedantibody or T-cell responses and improved clinical outcome,clearance of melanoma markers from the circulation, improved survivalcompared to historical controls, and most convincingly, two randomizedtrials in which the recurrence-free survival of vaccine-treatedpatients was significantly longer than that of control groups.
Leukemias and lymphomas are estimated to contribute up to 7% of all new malignant cases in the United States.[1]
Integrins have direct effects in stimulating proliferation and preventing apoptosis in cancer cells and mediating proangiogenic interactions between endothelial cells and extracellular matrix. Alterations of expression of various integrins and their receptors have been observed in various cancers in which angiogenesis is known to play a role, including colorectal cancer. Inhibition of specific integrins might thus inhibit both direct effects of integrins on cancer cells and tumor angiogenesis. Inhibitory peptides and anti-integrin monoclonal antibodies are currently being investigated in clinical trials in patients with solid tumors, with early evidence suggesting clinical benefit in disease stabilization with use of an anti-αvβ3 antibody in the settings of colorectal cancer, renal cell carcinoma, and melanoma. Integrin inhibition alone and with other targeted therapeutic approaches should be further investigated in clinical trials in patients with colorectal cancer.
