The use of high-intensity focused ultrasound (HIFU) as a method for ablation of a localized tumor growth is not new. Several attempts have been made to apply the principles of HIFU to the treatment of pelvic, brain, and gastrointestinal tumors. However, only in the past decade has our understanding of the basic principles of HIFU allowed us to further exploit its application as a radical and truly noninvasive, intent-to-treat, ablative method for treating organ-confined prostate cancer. Prostate cancer remains an elusive disease, with many questions surrounding its natural history and the selection of appropriate patients for treatment yet to be answered. HIFU may play a crucial role in our search for an efficacious and safe primary treatment for localized prostate cancer. Its noninvasive and unlimited repeatability potential is appealing and unique; however, long-term results from controlled studies are needed before we embrace this new technology. Furthermore, a better understanding of HIFU's clinical limitations is vital before this treatment modality can be recommended to patients who are not involved in well-designed clinical studies. This review summarizes current knowledge about the basic principles of HIFU and its reported efficacy and morbidity in clinical series published since 2000.

After 2 decades of disappointing phase III trials and years of single-agent gemcitabine therapy, the pancreatic cancer community is relieved to expand the front-line armamentarium in patients with mPAC. Here we evaluate the current landscape and ask some provocative questions about response rate, dosing, and predictive markers.

It is time to develop more active treatments in the early-disease setting that actually eradicate ER-positive breast cancer before new mutations and secondary resistance have a chance to develop. In this regard, standard chemotherapy is not the answer.

However, it is becoming ever clearer that tumor characteristics can change during the course of disease. Given this change over time, other supporting techniques for guiding therapy would be of value. Molecular radionuclide imaging with positron emission tomography (PET) can potentially fulfill this need.

Priming of leukemic cells with cytokines may enhance the efficacy of cell-cycle chemotherapy. In this study, we utilized these synergistic effects of granulocyte-macrophage colony-stimulating factor (GM-CSF, sargramostim [Leukine]), hydroxyurea, and low-dose cytosine arabinoside to treat elderly patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS). In a single-institution, retrospective study, we evaluated 94 treatments with concomitant hydroxyurea, cytosine arabinoside, and GM-CSF between the years of 1997 and 2003 in high-risk elderly patients with AML or MDS. A total of 80% of patients received all of the GM-CSF doses; 78% of patients received all of the cytosine arabinoside doses. Adverse events were minimal. No patient developed mucositis or alopecia. The most common adverse event was neutropenic fever, which was noted in 57% of patients. Twenty-one percent of patients remained neutropenic after treatment until death or relapse. Sixty-eight percent of patients reached an absolute neutrophil count of greater than 1,000 μL in a median of 33.5 days. Our data show an overall response rate of 52%, with a complete response rate of 39% and a partial response rate of 13%. Overall, our study showed that low-dose cytosine arabinoside given by continuous infusion together with continuous infusion GM-CSF and hydroxyurea was well-tolerated and effective in treating elderly AML and MDS patients who were not eligible for standard induction therapy.

Colorectal cancer is one of the leading causes of cancer-related death worldwide, with almost 20% of all patients presenting with metastatic disease at the time of their diagnosis. The treatment regimens and options of metastatic colorectal cancer have significantly changed in the last 10 years, leading to an improvement of response rates to about 50%, progression-free survival of about 10 months, and overall survival reaching over 2 years.

Significant improvements in the management of patients with endstagerenal disease (ESRD) who are on chronic renal replacementtherapy (CRRT), has led to an increased prevalence of this populationamong older Americans. Since cancer is also common in the elderly,oncologists are likely to be faced with patients who suffer from bothcancer and ESRD. There is a paucity of information regarding issuessurrounding the optimal management of such patients, especially thoseneeding chemotherapy. This review surveys the relevant problemsoncologists may encounter in such patients and summarizes the availableliterature on chemotherapeutic management of common cancers.The reader is strongly urged to consult the original references for detailsof chemotherapy administration prior to use in an individualpatient.

The use of erythropoietic growth factors to treat chemotherapy-induced anemia (CIA) has been increasing as clinicians become more aware of the ability of these drugs to improve the quality of life of patients with cancer. The cost associated with erythropoietic growth factor therapy makes its appropriate use a practical issue for physicians and hospitals. Clinical practice guidelines can benefit physicians by increasing practice efficiency, reducing medical errors, increasing the quality of medical care, and decreasing reimbursement problems. The American Society of Clinical Oncology and the American Society of Hematology, the European Organisation for Research and Treatment of Cancer, and the National Comprehensive Cancer Network (NCCN) have all published guidelines for using erythropoietic growth factors to treat CIA, and this article reviews and summarizes those guidelines. Of the three guidelines for the use of erythropoietic growth factors in CIA, the NCCN guidelines are based on the most recent data. Current evidence indicates that erythropoietic growth factors can increase hemoglobin levels, reduce the need for red blood cell transfusions, and improve quality of life; the effect of erythropoietic therapy on outcomes in patients with CIA is still being investigated.
