This video reviews the use of endoscopic therapy for the management of Barrett esophagus and early esophageal cancer.
Squamous cell carcinomas of the head and neck are highly responsiveto induction chemotherapy. However, randomized trials have failedto demonstrate a survival advantage with the addition of induction chemotherapyto locoregional therapy consisting of surgery and/or radiationtherapy. Currently, concomitant radiation and chemotherapy hasemerged as a standard and has optimized locoregional control in headand neck cancer. In this setting, the addition of induction chemotherapymay further improve outcome by enhancing both locoregional and distantcontrol. As interest in induction regimens is renewed, we elected toconduct a systematic review of trials of induction chemotherapy forlocoregionally advanced head and neck cancer. The most studied combination-cisplatin plus fluorouracil (5-FU)-achieves objective responserates of about 80%. In a meta-analysis, induction with platinum/5-FU resulted in a small survival advantage over locoregionaltherapy alone. The introduction of a taxane into induction chemotherapyregimens has produced promising results. Induction chemotherapyshould be the subject of further clinical research in head andneck cancer. Randomized clinical trials in which the control arm isconcurrent chemoradiotherapy and the experimental arm is inductionchemotherapy followed by concurrent chemoradiotherapy are planned.Platinum/taxane combinations are the preferred regimens for furtherstudy in the induction setting and a suitable platform with which toinvestigate the addition of novel targeted agents.
Ibritumomab tiuxetan (Zevalin) consists of an anti-CD20 murine IgG1 kappa monoclonal antibody covalently bound to tiuxetan (MX-DTPA), which stably chelates yttrium-90 for therapy. Ibritumomab tiuxetan therapy involves pretreatment with
We present a joint perspective from the medical oncology and urologic disciplines on the ongoing efforts to advance clinical trial performance in order to discover new therapies for this fatal disease.
Rural cancer patients often face substantial barriers to receiving optimal treatment, including availability of cancer care providers, distance to services, lack of public transportation, financial barriers, and limited access to clinical trials. However, a number of promising approaches may address some of these challenges.
Richter's transformation, or Richter's syndrome, is an uncommon clinicopathological condition observed in about 5% to 10% of patients with chronic lymphocytic leukemia (CLL). This review summarizes advances in our understanding of the pathobiology and in the management of Richter's transformation in patients with CLL.
This review focuses on the clinicopathologic and molecular features of epithelial ovarian cancer, with specific attention to genetic predisposition, morphologic challenges, immunohistochemistry, and molecular features.
Soyfoods are consumed by many because of cultural factors, for potentialThere are strongly conflicting data regarding soy intake and breast cancer. As such, if women (with or without breast cancer) enjoyed partaking of soy products, then it seems quite reasonable for them to partake of them. As with most things, moderation in intake is probably wise. beneficial effects on overall health, and for the unproven hope that they will ease menopausal symptoms in women.[1]
Multiparametric MRI is a promising tool for identifying cancer within the prostate. It has the potential to drastically change the way prostate cancer is staged and treated. However, work remains to make this technique reproducible and accessible to the community-based radiologist and urologist.

Combinations of gemcitabine (Gemzar) with cisplatin (Platinol) are among the most active new chemotherapy regimens developed for advanced non-small-cell lung cancer. Carboplatin (Paraplatin) is a platinum analog
There are several million breast cancer survivors worldwide. In the United States, 180,000 women were diagnosed with breast cancer in 1997, and approximately 97,000 of these women have an extremely low chance of a suffering a recurrence of their cancer. With an average age at diagnosis of 60 years and a 25-year expected duration of survival, the current number of breast cancer survivors in the United States may approach 2.5 million women. Since breast cancer is now being detected at an earlier stage than previously and since adjuvant chemotherapy may cause ovarian failure, an increasing number of women are becoming postmenopausal at a younger age after breast cancer treatment. This conference was convened in September 1997 to consider how menopausal breast cancer survivors should be treated at the present time and what future studies are needed to develop improved therapeutic strategies. A total of 47 breast cancer experts and 13 patient advocates participated. The proceedings of the conference are being published in six installments in successive issues of oncology. This third part focuses on the prevention of osteoporosis and the cardiovascular effects of estrogens and antiestrogens. [ONCOLOGY 13(3):397-432, 1999]
Women who are infected with human immunodeficiency virus (HIV) are at greater risk for the development of lower genital tract neoplasia than are HIV-negative women. Among HIV-positive women, those who are more
The purpose of this review is to provide the oncology community with knowledge about the doses used in medical imaging, radiation-induced cancer risks from imaging, and considerations to keep in mind when balancing imaging benefits and risks in pediatric and adult oncologic settings.
Some targeted systemic therapies have demonstrated evidence of activity in the brain-specifically in melanoma, lung cancers, and breast cancers-and these agents warrant further study in clinical trials.
In July 2003, an asymptomatic 40-year-old man presented to his primary care physician for routine care and was found to have a palpable right axillary lymph node.
Malnutrition plays a key role in the morbidity of head and neckcancer patients receiving surgery, chemotherapy, radiotherapy, or combined-modality therapy. In addition to weight lost prior to the diagnosisof head and neck cancer, the patient may lose an additional 10% ofpretherapy body weight during radiotherapy or combined-modality treatment.A reduction of greater than 20% of total body weight results inan increase in toxicity and mortality. Severe toxicity can result in prolongedtreatment time, which has been implicated in poor clinical outcome.Early intervention with nutritional supplementation can reducethe chance of inferior outcome in patients at high risk of weight loss.The preferred route of nutritional support for these patients is enteralnutrition. Two commonly used methods for enteral feedings arenasoenteric and percutaneous endoscopic gastrostomy. It is importantto take into account the ethical considerations involved in providinglong-term nutritional support, particularly for patients with terminalconditions. Nutritional directives are best evaluated throughmultidisciplinary efforts, including input from the patient as well asmembers of the nursing, nutritionist, and medical staff.
Esophageal, gastroesophageal junction, and gastric cancers are underpublicized but are frequently lethal, and gastroesophageal junction adenocarcinomas are increasingly common diseases in the United States and around the world. Although often grouped together in studies of chemotherapy, clear distinctions can be made in the locoregional therapy of these diseases. Esophageal squamous cell carcinomas may be treated with surgery or radiation with concurrent chemotherapy, whereas esophageal adenocarcinomas and gastroesophageal junction adenocarcinomas are often treated with all three treatment modalities. Over the past several years, it has become increasingly evident that gastric cancer is a disease that is potentially sensitive to chemotherapy. In the perioperative setting—at least in the Western world—chemotherapy and sometimes radiation are applied. However, the optimal chemotherapy for advanced gastric or esophageal cancer remains unsettled, and there is no single standard regimen. Several new chemotherapy agents have demonstrated activity in these diseases, but the best chemotherapy remains to be determined. This paper will review the role of chemotherapy in gastroesophageal cancers.
To determine the most effective strategies for the treatment of postmenopausal hormone dependent breast cancer, we recently developed a model system in nude mice. In this model, estrogen receptor-positive human breast cancer cells (MCF-7) stably transfected with the aromatase gene are inoculated into ovariectomized, immunosuppressed (nude) mice.
Following studies that found no survival or mortality benefit, we discuss the utility of primary androgen deprivation therapy in localized prostate cancer.
We previously reported the efficacy of concurrent cisplatin (Platinol)/etoposide (PE) and radiotherapy in stage IIIB non–small-cell lung cancer in which biopsy confirmation of T4 (noneffusion) or N3 status was required (S9019). In view of the activity of docetaxel (Taxotere) as second-line therapy and potential molecular mechanisms of action favoring taxane sequencing, we designed the present study to maintain a core of concurrent PE/radiotherapy, but to substitute docetaxel consolidation for the two additional cycles of PE.
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.
For many years, tamoxifen has been the gold standard adjuvanthormonal therapy with the greatest impact in early breast cancer forboth pre- and postmenopausal women. Tamoxifen-based adjuvant endocrinetherapy and chemotherapy have together contributed substantiallyto the reduction in breast cancer mortality that has occurred inrecent years. Over the past few years, the role of aromatase inhibitorshas grown in prominence and they are now on the threshold of supplantingtamoxifen as the new gold standard adjuvant therapy for postmenopausalwomen with estrogen-receptor–positive disease. With extendeduse of oral antihormones such as tamoxifen, the role of ovariansuppression on the other hand has become less clear in the adjuvantsetting. This article reviews the most important data regarding the variousadjuvant hormonal treatments in the management of early breastcancer and will also give a brief overview of the role of these agents inthe neoadjuvant setting.
The paper by Salvatore et al discusses a very broad, complex subject, which, in some aspects, is quite controversial. The review touches on many different topics but not always in enough detail to provide clarity. Pertaining to the debated link between 50 to 60 Hz power line field exposure and cancer, the authors characterize their article as "... a review of the basic science that points to this possible association [with cancer]." However, the "basic science" that "points to" occupies much of their presentation, while some major types of evidence and reasoning that "points away" is not mentioned.
The perception and reality of the clinical value of erythropoiesis-stimulating agents (ESAs) in cancer supportive care have undergone a dramatic transformation since their initial use in 1990. The perception of ESA value in patients has evolved from panacea to miscreant over a 2-decade period of laboratory research, clinical trial data, and postmarketing experience. Meanwhile, the real clinical benefits of ESAs have changed very little from those described in the joint American Society of Clinical Oncology/American Society of Hematology guidelines originally published in 2002.[1] Even then, the value of initiation of ESAs was clear only in patients with hemoglobin values < 10 g/dL; quality-of-life measures produced inconsistent and, therefore, clinically inapplicable, results; and ESA use was shown to reduce the proportion of patients requiring red blood cell (RBC) transfusions by approximately 20%. The reality of ESA use that came to light following approval was increased mortality rates in certain populations, higher tumor progression and cancer recurrence rates, and more frequent and severe serious adverse effects including thromboembolism, stroke, and cardiovascular events.
The best management of distress in a lung cancer patient involves aggressive physical symptom control, attention to concerns about death, and psychosocial support for the patient and his or her caregivers, as well as management of more typical psychiatric symptoms.
The article by Thieblemont and colleagues very nicely summarizes the key pathogenetic and diagnostic features and present treatment of splenic marginal zone lymphoma (SMZL).
