Uracil and tegafur (in a molar ratio of 4:1 [UFT]) has proven activity against breast cancer and is delivered in an easy-to-administer oral formulation. Orzel, which combines UFT with the oral biomodulator, calcium folinate, may
Pemetrexed (Alimta) possesses broad antitumor activity. It has beenevaluated in non–small-cell lung cancer (NSCLC) as front-line chemotherapyin a comprehensive phase II evaluation. While variousantifolates have been previously evaluated in clinical trials, drug developmentwas stopped or delayed in light of their lack of efficacy oroccurrence of life-threatening toxicities. While similar trends were observedwith pemetrexed early in development, investigators institutedfolic acid and vitamin B12 supplementation to minimize these toxicitieswithout hampering drug efficacy. This article briefly summarizes thecurrent evidence that supports the role of pemetrexed-based combinationsin clinical trials for chemonaive patients with advanced NSCLC.
As noted in part 1 of this two-part article, non-Hodgkin's lymphoma is one of a few malignancies that have been increasing in incidence over the past several decades. Likewise, these disorders are more common in elderly patients, with a median age of occurrence of 65 years. Therapy in elderly patients may be affected by multiple factors, especially attendent comorbidities. The approaches to management of these patients, with either indolent or aggressive disease processes, have been based on prospective clinical trial results, many of which have included a younger patient population. Fortunately over the past decade, results of treatment trials that have targeted an older patient population have emerged. The disease incidence and treatment approaches for both follicular (part 1) and diffuse aggressive (part 2) histologies in elderly patients are reviewed, as well as the impact of aging on the care of these patients.
Here we review current guidelines on breast and ovarian cancer screening, prophylactic surgery, and other risk-reduction strategies in patients with these mutations, and we detail the data that drive these recommendations.
Upfront surgery allows for greater freedom to use all secondary treatment options for local and distant control, including adjuvant radiotherapy and ADT, thereby hopefully obviating the significant adverse quality-of-life sequelae from salvage surgery and brachytherapy for local relapse.
The VA Cancer of the Prostate Outcomes Study (VA CaPOS) is collecting quality-of-life (QOL) information from prostate cancer patients, spouses, and physicians at six VA medical centers. Currently, 601 men with prostate
Rosen and colleagues have provided a comprehensive review of the biological basis of radiation sensitivity, including recent insights into the DNA damage response. They correctly emphasize that local control of tumors is still a major clinical problem, and that a better understanding of the biological basis for radiation resistance/sensitivity has significant potential to be exploited for therapeutic gain. They also assert that further progress in local tumor control is unlikely to be achieved by technologic improvements in the delivery of such radiation therapies as three-D (3D) conformal radiotherapy, intensity-modulated radiation therapy (IMRT), altered fractionation, or even chemosensitization.
Over the past 5 years, several studies have investigated the molecular profiling of penile carcinomas, examining both genomic and epigenetic alterations. These studies have revealed distinct molecular pathways associated with HPV status.
Liposomes have been proposed as potential vehicles for drug therapy targeted to solid tumors, in particular, because of the increased permeability of these tumors to macromolecules. The recent development of Stealth
Commonly used by cancer patients, unproven therapies are treatments that the practitioner claims can alter the disease process although there is no proof to support the claim. The reasons for the popularity of uproven
Accelerated partial-breast irradiation is a shorter, alternative radiation technique for select patients with favorable early-stage breast cancer. We review here the different modalities of delivery and discuss the possible benefits and harms associated with these treatments.
I read with great interest the paper by Michael Brave and colleagues from the US Food and Drug Administration (FDA). The authors describe the FDA's review supporting this first approval of a chemotherapeutic drug for advanced cervical cancer. This decision was made after a Gynecologic Oncology Group trial (GOG-0179) conducted at 94 American study centers demonstrated a survival benefit in patients with stage IVB, recurrent, or persistent carcinoma of the cervix who received cisplatin plus topotecan (Hycamtin) compared with those who received cisplatin alone.
Tumors of neuroendocrine origin arising from the pancreas, luminal gastrointestinal tract, and other tissues differ greatly in their malignant potential.
The presence of regional nodal metastases represents a significantadverse prognostic factor for patients with squamous cell carcinoma ofthe head and neck. Early-stage head and neck cancers, localized to theprimary site without regional lymph node metastases have excellentcure rates with either surgery or radiation therapy. The presence ofregional metastases results in cure rates that are approximately half ofthose obtainable in early-stage disease. Therefore, due to the significantadverse impact of neck metastases on prognosis, the treatment ofthe neck remains a vital part of the decision-making process in determiningtherapy for head and neck cancer.
Our commentary aims to expand on the evolution and present state of the art in the pathology of HPV in penile cancer and precancerous lesions.
Since its early descriptions by Lee and Tannenbaum in 1924, inflammatory breast cancer (IBC) has been recognized as the most aggressive and lethal form of primary breast cancer. With distinct clinical, pathologic, biologic, and molecular features, IBC presents unique challenges and opportunities to breast oncologists and breast cancer researchers.
DLBCL of any stage remains a systemic disease with early hematogenous spread. Thus, arguments advocating the role of IFRT do not truly address disease biology, and all future efforts to cure patients will require improved systemic therapy.
Developed initially for the treatment of malignant melanoma, lymphatic mapping and sentinel lymph node biopsy have recently been introduced into the treatment of early breast cancer. In breast cancer patients, harvested
In spite of the complicated etiologic, clinical, and pathologic scenario of cryoglobulinemia, physicians can play a key role in its successful management by early recognition of the most common clinical presentations.
A 40-year-old premenopausal woman with a new diagnosis of invasive lobular carcinoma occurring in a background of lobular carcinoma in situ presents to a multidisciplinary second opinion clinic.
This review article written by Kirk E. Cahill, MD, and Sonali M. Smith, MD, discusses standard and emerging therapies for the treatment of follicular lymphoma.
This video examines the results of a retrospective study that compared chemotherapy alone or with prophylactic cranial irradiation in extensive-stage SCLC patients with no brain metastases.
This report describes the Food and Drug Administration's review of data and analyses leading to the approval of the oral iron chelator, deferasirox for the treatment of chronic iron overload due to transfusional hemosiderosis.
In this interview we discuss updates, challenges, and contributing factors associated with pediatric brain cancers.
Many cancer patients are undermedicated and inappropriately managed for pain, leading to a diminished quality of life. Patients with moderate to severe pain often require opioid analgesics. Recently published guidelines
Topotecan, a camptothecin analog previously approved for the treatment of ovarian cancer and small-cell lung cancer, was granted regular approval by the US Food and Drug Administration (FDA) on June 14, 2006, for use in combination with cisplatin to treat women with stage IVB, recurrent, or persistent carcinoma of the cervix not amenable to curative treatment with surgery and/or radiation therapy. The purpose of this summary is to review the database supporting this approval.
In a step toward a clinical trial, the tumor response and survival of a weekday-on/weekend-off schedule of UFT was compared with its conventional daily schedule in a cancer-bearing rat model. The dose-intensive schedule-600 mg of UFT for 5 days followed by 2 drug-free days-amounts to a weekly dose similar to the conventional schedule of 400 mg/day. The weekday-on/weekend-off schedule provided increased survival and significantly greater antitumor activity than the conventional daily schedule, with no difference in adverse reactions.
Momelotinib continues to show benefit in reducing splenic symptoms and anemia in myelofibrosis in the second-line setting, making it a likely first treatment choice, according to an expert from the University of Texas MD Anderson Cancer Center.
The study of cancer in specific populations can offer clues useful in determining the extrinsic and intrinsic factors influencing cancer in all populations. Extrinsic factors are sometimes called "environmental" in the broadest sense of the word. They are modifiable or mutable. Intrinsic factors are more inherent to the individual. They are almost always genetic and are immutable or unchangeable. Targeting research on specific populations is and should be a significant ethical issue.
A phase II trial evaluated the effectiveness and toxicity of combination paclitaxel (Taxol), gemcitabine (Gemzar), and trastuzumab (Herceptin) as first-line therapy for patients with newly diagnosed HER2-overexpressing
