Gastric cancer is the most chemosensitive adenocarcinoma among digestive neoplasms. A few years ago, we performed a phase II trial with the FLEP regimen, in which fluorouracil (5-FU) and leucovorin are combined
Thirty-three metastatic breast cancer patients with prior chemotherapy (adjuvant alone, 9 patients; chemotherapy for metastatic disease alone, 13 patients; chemotherapy for both, 11 patients) received paclitaxel (Taxol) 135
For the clinician who is facedwith treating individual patients,the article by Ornstein and Petricoinmight raise the famous questionfrom the Wendy’s commercial:Where’s the beef? When we hear ofthese Star Wars technologies and complexexplanations, we are often frustrated.On the one hand, we havenothing to offer our patients right now,and on the other, our patients readabout these technologies and expectthem to be applied right now.
A better delineation of the relationships between lung cancer, COPD, and emphysema may lead to significant improvements in the effectiveness of lung cancer screening programs, and to reductions in the morbidity and mortality associated with these deadly diseases.
Two studies were carried out to determine the activity and evaluate the toxicity of oral chemotherapy with uracil and tegafur in a 4:1 molar ratio (UFT) plus or minus calcium folinate in elderly patients with advanced colorectal
Historically, patients with retroperitoneal sarcomas have had a poor prognosis. Surgical resection continues to be the standard treatment for these tumors. However, their anatomic location and large size at presentation often
The widespread use of the TNM staging system has helped standardize the classification of cancers. Despite its excellence in describing a tumor's size and extent of anatomic spread, the TNM system does not account for the clinical biology of the cancer.
It is ironic that the issue of aggressive local therapy for breast cancer has re-emerged as a controversial issue in the early 1990s, almost 100 years after Halsted proposed this theory in the early 1890s [1]. Since that time, both survival and quality of life seemed to have improved for patients with breast cancer, due to more sophisticated and effective treatments. Nonetheless, as Drs. Pierce and Lichter point out in their article, the precise balance between the benefits and risks of aggressive local therapy still remains to be defined.
The comparison of brachytherapy and surgery may be done on several levels. This review focuses the comparison on toxicity, the “soft” endpoints of biochemical relapse-free survival and clinical relapse-free survival, and the “hard” endpoint of prostate cancer–specific mortality.
Given their greater convenience and, in most cases, decreased costs, APBI and AWBI are becoming increasingly popular alternatives to conventional WBI for early-stage breast cancer patients who desire BCT. However, given the protracted time to local recurrence and complications following BCT, definitive results from randomized clinical trials comparing conventional WBI vs AWBI or APBI are limited.
Dyspnea is defined as a sensation of difficult or uncomfortable breathing. The symptom is highly prevalent among cancer patients with and without direct lung involvement. The gold standard of assessment is based on
Malignancies have been detected in approximately 40% of all patients with acquired immunodeficiency syndrome (AIDS) sometime during the course of their illness.
Intracranial neoplasms can arise from any of the structures or cell types present in the cranial vault, including the brain, meninges, pituitary gland, skull, and even residual embryonic tissue.
PARP inhibitors are an active, novel, and exciting class of anticancer agents. They have shown clear patient benefit in gBRCA, HR-deficient, and other ovarian cancers.
Antibody-based targeting of the immune suppressor molecule cytotoxic T-lymphocyte antigen 4 (CTLA-4) with ipilimumab has been studied in metastatic melanoma in a number of clinical trials, including a recent phase III trial. This marks the first randomized clinical trial reporting an overall survival benefit using immune modulation in metastatic melanoma. Along with its therapeutic benefits, ipilimumab presents unique challenges to clinicians; these are related to the monitoring of treatment response and the management of drug-related toxicities. This drug is currently being investigated in various cancers, and its indications are likely to be expanded.
A 60-year-old man presented with lower limb claudication and a painful mass on his left buttock. Physical examination revealed a firm round mass, fixed to deep planes. A biopsy was performed and revealed a chordoma.
It is ironic that while huge strides have been made in the treatment of invasive breast carcinoma, resulting in breast conservation for many women, the most appropriate treatment of noninvasive breast carcinoma remains a topic of hot debate.
This was an open lable, pilot translational clinical pharmacology study of a brief (7 day) course of UFT, 300 mg/m²/day, in combination with leucovorin, 90 mg/day, in six patients with newly diagnosed advanced colorectal cancer.
With regard to cancer management, minority populations do not fare as well as the majority in the US health-care system. There is clear evidence of an increased incidence of cancer in minority populations, in many cases accompanied by reduced survival. Several factors appear to contribute to these differences, and the biomedical community has begun to focus on definining the scope of the problem and possible solutions. This review will address specific areas of disparity in cancer care, including prevention, diagnosis, treatment, and outcomes, and will consider steps toward resolving these issues.
Cetuximab (Erbitux), a chimeric antiepidermal growth factor receptor monoclonal antibody currently used to treat metastatic colorectal cancer, is in clinical development for several other solid tumors. Although cutaneous manifestations are the most common toxicities associated with cetuximab, they are rarely life-threatening. Cetuximab-related infusion reactions are less common, but they may become severe and cause fatal outcomes if not managed appropriately. Little about the specific etiology of these events is known; however, an overview of infusion reactions observed with other compounds may shed some light and help characterize cetuximab-related reactions. For physicians administering cetuximab, familiarity with acute reaction treatment protocols and preparedness to identify and manage symptoms promptly and effectively are most important to minimize potential risks.
Monoclonal antibodies to the epidermal growth factor receptor (EGFR) are among the promising novel targeted therapies being explored in colorectal cancer. Two such agents that inhibit EGFR signaling by interfering with ligand-binding are cetuximab (Erbitux) and panitumumab (Vectibix). This review will address the use of cetuximab and panitumumab in chemotherapy-refractory colorectal cancer as well as in front-line therapy for the disease, consider predictors of response and resistance, and outline comparisons between these agents.
This review will cover innovative therapeutic approaches in relapsed or refractory MCL, many of which have the potential to alter treatment paradigms toward the development of strategies that do not involve conventional chemotherapy agents.
There is no doubt that managed care is changing health care and the practice environment of all health-care providers. As Baird states, “The economics of health care will probably exert a greater influence on the future practice of nursing than any other single factor.”[1]
This was an open lable, pilot translational clinical pharmacology study of a brief (7 day) course of UFT, 300 mg/m²/day, in combination with leucovorin, 90 mg/day, in six patients with newly diagnosed advanced colorectal cancer.
In this review, we will discuss multidisciplinary considerations in treating patients with neoadjuvant therapy and highlight areas of controversy and ongoing research.
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.
Customized more aggressive treatments should be given to patients with the worst prognosis. For most of the other breast patients, shorter and often milder treatment is also a humble victory in our daily struggle against cancer.
Single-agent gemcitabine (Gemzar) is the standard of chemotherapyfor advanced pancreatic cancer, with no phase III trials to date havingshown significantly improved survival with gemcitabine-based combinationsvs single-agent treatment. The multitargeted antifolate agentpemetrexed (Alimta) shows synergistic effects in vitro in combinationwith gemcitabine, and activity and good tolerability when used as singleagenttreatment in advanced pancreatic cancer. In a phase II trial inpatients with advanced pancreatic cancer, the combination ofgemcitabine at 1,250 mg/m2 on days 1 and 8 plus pemetrexed at 500mg/m2 on day 8 after gemcitabine every 21 days resulted in a mediansurvival of 6.5 months and a 1-year survival rate of 29%. Neutropeniawas the primary toxicity, with grade 4 toxicity in 51% of patients. Thepromising results of this trial prompted the initiation of a phase IIItrial comparing gemcitabine at 1,000 mg/m2 on days 1, 8, and 15 every28 days vs the 21-day gemcitabine/pemetrexed regimen given with vitaminsupplementation in patients with pancreatic cancer. The primaryoutcome measure was overall survival, with secondary measures includingresponse rate, progression-free survival, and quality of life.While an increase in response and time to progression was reported forthe gemcitabine/pemetrexed combination, there were no significantdifferences in survival between treatment arms.
Until recently, standard treatment of multiple myeloma (MM) in elderly patients who were not candidates for autologous stem cell transplantation was with the combination of melphalan plus prednisone (MP). Novel agents (thalidomide, lenalidomide, bortezomib) are dramatically changing frontline therapy of MM. Randomized studies have shown the superiority of adding one novel agent to MP, either thalidomide (MPT) or bortezomib (MPV). The combination of lenalidomide with low doses of dexamethasone is another attractive alternative. Recent results show that maintenance therapy with low-dose lenalidomide may prolong progression-free survival. The objective of these improved treatment regimens should be to achieve complete response, as in younger patients. However, toxicity is a significant concern, and doses of thalidomide and of myelotoxic agents should be reduced in patients who are older than 75 years or who have poor performance status. Weekly bortezomib appears to induce severe peripheral neuropathy less frequently than the same agent administered twice weekly. Autologous stem cell transplantation is feasible in selected fit patients over 65 years of age, and its results are improved by the addition of novel agents before and after high-dose therapy. However, considering the progress in non-intensive therapy, autologous transplantation should not currently be offered to elderly patients outside of a clinical trial.
Preliminary results from phase I trials suggest that the use of docetaxel (Taxotere) and doxorubicin (Adriamycin) is a well tolerated and highly active combination regimen for
