The world’s first clinically operational molecular imager with lutetium oxyorthosilicate (LSO) technology-the biograph LSO, manufactured by Siemens Medical Solutions-has produced a precisely registered, combined positron-emission tomography (PET)/computed tomography (CT) image in 7 minutes at the Hong Kong Baptist Hospital. The biograph LSO imager uses the high-speed properties of LSO as the PET scintillator to provide shorter scan times and unmatched patient throughput.

The National Cancer Institute (NCI) announced recently that it is expanding access to its clinical trials to more oncologists around the country. This new policy will allow cancer patients anywhere in the United States to participate more easily in advanced (phase III) treatment trials.

In a recent issue of the Journal of the American College of Surgeons (194:648-656, 2002), a collective review led by Monica Morrow, MD, director of the Lynn Sage Comprehensive Breast Center at Northwestern Memorial Hospital in Chicago, presented recommendations on the use of ductal lavage in women at high risk for breast cancer. The article offers guidance on which women are most appropriate for ductal lavage and on how abnormal ductal lavage results should be managed.

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.

A study conducted by researchers at Duke University and Johns Hopkins Medical Centers and published in the journal Cancer (94:987-996) found that the use of indium-111-capromab pendetide (ProstaScint), a radiolabeled monoclonal antibody imaging agent, allowed identification of recurrent prostate cancer earlier than conventional imaging methods, such as the computed tomography (CT) scan. Prostate cancer recurs in nearly 40% of patients, and about 11% are at high risk for metastatic spread of the disease. Conventional imaging methods are often only able to detect a more advanced stage of prostate cancer.

Oncology care will be the focus of one of the new Medicare disease management demonstration programs soon to be initiated. Medicare remains convinced that disease management services can provide substantial savings. There is, however, a problem: Fee-for-service Medicare, which includes most recipients, does not allow for disease management, except in one or two instances, such as diabetes self-education. The Medicare+Choice program-comprised mostly of health maintenance organizations-offers disease management, but seniors have, for the most part, avoided this plan. Therefore, Medicare has selected 15 sites for case management and disease management services, which will be offered to Medicare fee-for-service beneficiaries with complex chronic conditions. Quality Oncology, Inc, of McLean, Va, will implement an urban disease management program targeting beneficiaries in Broward County, Fla.

Bedford Laboratories announced that it has received approval from the Food and Drug Administration to market pamidronate disodium for injection. The product will be the only liquid version available on the market, and is equivalent to the Novartis pamidronate disodium product (Aredia), a bone resorption inhibitor indicated for the treatment of hypercalcemia associated with malignancy, for Paget’s disease, and for osteolytic bone metastases of breast cancer and osteolytic lesions of multiple myeloma.

A study published in the journal Cancer (94:2327-2332, 2002) suggests that African-Americans who have colon cancer and live in poverty are at much greater risk of dying from the disease.

New clinical practice guidelines, published in a recent issue of the Journal of the American Medical Association (287:2120-2129, 2002), recommend that women who receive borderline Papanicolaou (Pap) test results designated as atypical squamous cells of undetermined significance (ASCUS)-a finding in more than 2 million American women each year-undergo testing for human papillomavirus (HPV). In clinical studies, HPV has been shown to be the primary causal factor in the development of cervical cancer.

A bipartisan group of House of Representatives members is trying to pass a medical malpractice reform bill. Medical liability reform disappeared along with the Patients’ Bill of Rights, in which it was included, when the House and Senate failed to agree on a compromise version of the bill at the end of 1999.

InTouch magazine, a sister publication of ONCOLOGY and Oncology News International, has been selected by the National Library of Medicine to be indexed and included in Index Medicus and Medline. InTouch is published by PRR for cancer patients and their families.

The US Food and Drug Administration (FDA) has granted approval to AstraZeneca’s new breast cancer drug fulvestrant (Faslodex) for treatment of hormone-receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy, with, for example, tamoxifen. Fulvestrant is an estrogen-receptor antagonist without known agonist effects. It is the only estrogen-receptor antagonist to be proven effective after tamoxifen failure.

Payne, Coyne, and Smith present a concise review of the surprisingly meager literature regarding costs of end-of-life cancer care, an issue with substantial ethical and financial implications. They present evidence that improved coordination of care holds the potential to lower costs, or at least to offer better services at the same cost. The authors are to be commended for pursuing more rigorous studies regarding this difficult-to-quantify area of medical and social services. Moreover, they appropriately highlight the difficulties in attempting to capture direct costs of medical care and the far more elusive indirect costs.

The non-Hodgkin’s lymphomas (NHL) are the fifth most common cause of cancer in men and women in the United States, and the fifth and sixth leading causes of cancer deaths, respectively. Approximately 54,000 new cases are projected to be diagnosed in the United States this year,[1] 25% to 30% of which are indolent histologies, with the remainder being aggressive tumors.

A 54-year-old female seeks medical attention with a complaint of worsening exertional dyspnea of 3 to 4 weeks’ duration. She has a history of small-cell lung carcinoma, first diagnosed 3 months previously, and has had an excellent response to treatment, which included both chemotherapy and external-beam radiation. Consistent with her cancer diagnosis, she has a 30 pack-year history of cigarette smoking, and her pulmonary function tests indicate mild airflow obstruction, slight hyperinflation on lung volumes, and a mildly decreased diffusion capacity. In addition to her dyspnea with exertion, the patient describes symptoms of an intermittently productive cough, fatigue, and, recently, a poor appetite.

Dr. Grigsby has done a masterful job of summarizing current information on the use of radiation in the management of patients with endometrial carcinoma. In the summary, he offers clear recommendations as to the appropriate management of various subsets of patients-recommendations that are based, at least to some extent, on the data reviewed. Such decision-making based on often incomplete information is necessary in the absence of appropriately designed randomized trials addressing the specific clinical situation. It is important, however, to understand clearly what we actually know and what we deduce from bits and pieces of data.

Drs. Ahrendt and Pitt should be congratulated on a comprehensive and well-presented review of the surgical management of pancreatic cancer. Unfortunately, pancreatic cancer continues to be a major cause of cancer-related death. The majority (80%) of patients still present with unresectable locally advanced or metastatic disease.

Adenocarcinoma of the pancreas remains a lethal malignancy: The majority of patients with pancreatic cancer continue to present with advanced disease and die within a year of diagnosis. Despite this grim fact, some progress has been made over the past decade, particularly in the surgical management of patients with resectable and advanced disease. This well-constructed review by Drs. Ahrendt and Pitt succinctly details the advances that have been made and highlights many of the unresolved issues.

I read with interest the commentary by Drs. Michael S. Givel and Stanton A. Glantz, regarding state-level disbursement of monies generated by the Master Settlement Agreement with Big Tobacco, which appeared in the February 2002 issue of ONCOLOGY.[1] Unfortunately, the authors omitted the key challenge facing antitobacco activists. Although they accurately depicted underfunding of tobacco control programs (~5% of total annual allocated payments)-far lower than levels recommended by the Centers for Disease Control and Prevention (~25%)[2]-they failed to analyze the deceptive nature of how the remaining funds are being categorized.

Often, Congressional financing of programs can be secured only with indirect arguments. In the 1950s, the Eisenhower administration convinced Congress to fund the interstate highway system by claiming it was essential to enable Americans to evacuate cities in case of a nuclear attack by the Soviet Union. In the 1970s, advocates trying to persuade Congress to pay for dialysis argued that the procedure would be inexpensive, and that people would return to work and pay for themselves. Similarly, in the early 1980s, proponents of hospice advocated Medicare coverage because it was cheaper and better care for the dying.

Dyspnea is an extremely common symptom among cancer patients.[1] Like pain, it is inherently subjective and is best defined as the perception of difficulty in breathing, or an uncomfortable awareness of breathing. Although it may be associated with one or more physiologic disturbances (such as hypercapnia, hypoxia, obstructive or restrictive patterns on pulmonary function tests, or various abnormalities on chest imaging studies), it is not strongly associated with any specific abnormality and may occur in the absence of any. Patient self-report is the gold standard for assessment and may range from mild breathlessness on exertion to a terrifying sense of suffocation.

Dr. Grigsby does an excellent job of summarizing the accepted, stage-by-stage treatment recommendations as well as the controversies surrounding the treatment of endometrial carcinoma. This review is both important and timely, as we have seen the incidence of endometrial cancer increase over the past few years to the point where it is now the most common gynecologic malignancy.

It is with great pleasure that I comment on the excellent article authored by Drs. Ahrendt and Pitt, who have provided a well-written, succinct, up-to-date review focusing on adenocarcinoma of the pancreas. The authors introduce the topic, discuss preoperative staging and assessment of resectability, cover the critical issues regarding resectional therapy and palliative surgery, and provide data on the results of such therapy, including mortality, morbidity, and quality-of-life outcomes. Emphasizing the importance of this topic, the authors note that pancreatic cancer is the fifth leading cause of cancer death in the United States.

The best clinical outcomes for patients with endometrial cancer seem to be achieved with either surgery alone or a combination of surgery and radiation therapy. Although once administered preoperatively, irradiation is now

The activity of docetaxel (Taxotere) as a single agent (overall response rates, 24%-45%) in the treatment of patients with recurrent squamous cell cancer of the head and neck has resulted in the investigation of docetaxel-based doublet and triplet combinations in both the recurrent and neoadjuvant settings. When combined with cisplatin, with or without fluorouracil (5-FU), in the treatment of recurrent disease, response rates of 33% to 44% have been observed for docetaxel, with median survival ranging from 9.6 to 11 months. In the neoadjuvant setting, response rates have been typically greater than 90%, with promising disease-free and overall survival results.

Phase II studies of single-agent docetaxel (Taxotere) yielded promising results in advanced or metastatic transitional cell carcinoma (TCC) of the urothelium. Antitumor responses have been demonstrated in previously treated and chemotherapy-naive TCC patients, as well as in a subgroup of patients with renal impairment unable to receive traditional cisplatin-based regimens.

Docetaxel (Taxotere) has extended the armamentarium of agents with significant activity in the treatment of ovarian cancer. As a single agent in advanced ovarian cancer patients previously treated with a platinum agent, docetaxel at 100 mg/m² every 3 weeks yields a 30% overall response rate and a 6-month duration of response.

Two phase III trials were conducted using docetaxel (Taxotere), administered every 3 weeks, as second-line treatment of non-small-cell lung cancer (NSCLC) in patients previously treated with platinum-based chemotherapy. In the TAX 317 trial, 204 patients were randomized to receive either docetaxel (49 received 100 mg/m² and 55 received 75 mg/m²) or best supportive care (100 patients). Median survival was 7.5 months with docetaxel at 75 mg/m² (D75) vs 4.6 months for best supportive care (P = .010); and 1-year survival was 37% for D75 vs 11% for best supportive care (P = .010).

Adjuvant chemotherapy is an integral component of the multidisciplinary curative treatment of primary breast cancers. The experience of the last 3 decades indicates that anthracycline-containing regimens provide the most effective cytotoxic treatment for this purpose.

Pancreatic cancer is the fifth leading cause of cancer death in the United States, with an overall survival rate of 3%. Unfortunately, only a minority of patients present with localized disease amenable to surgical resection.
