Evidence for Cure of ‘Young’ Men With Prostate CancerA study was undertaken to evaluate the question of cure in "young" men with prostate cancer treated by external-beam radiation. Results in young men (£ 65 years) were compared to older men. Biochemical freedom from failure was examined to 10 years’ follow-up, and hazard functions for failure vs time were reported. Results show that prostate cancer patients are cured by external-beam radiation and that there is no difference in results for young or older men. Few failures occur after 5 years’ follow-up and the percentage cured is similar to that with prostatectomy, with much less morbidity. Appropriate dose is necessary to optimize outcome.

Targeting Metastatic Colorectal Cancer in 2008: A Long Way From 5-FUColorectal 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.

Defining the IBC PhenotypeInflammatory breast cancer (IBC) is an aggressive and lethal form of breast cancer. It is also an entity for which no consensus exists regarding its clinical definition. The current nomenclature is considered a misnomer since its clinical presentation is not caused by inflammatory components but mainly by lymphatic obstruction.

Rare PTCLs: Treatment Lagging Behind Pathobiologic AdvancesPeripheral T-cell lymphomas, or PTCLs, represent an uncommon and biologically heterogeneous group of hematologic malignancies, accounting for less than 10% of all non-Hodgkin lymphomas worldwide, with marked geographic differences. Due to their low prevalence, variable clinical presentation and phenotypic heterogeneity, these lymphomas have historically been difficult to diagnose and categorize. Since the introduction of immunophenotyping and molecular genetic methods, as well as the development of comprehensive classification systems, there have been significant advances in diagnostic accuracy, classification, and our understanding of the biologic behavior of different PTCL subtypes. However, the molecular pathogenesis of most subtypes of PTCL remains incompletely understood, and treatment outcomes with conventional anthracycline-based chemotherapy regimens are generally significantly inferior to those in aggressive B-cell lymphomas.

Vaccine Therapy for Patients With MelanomaHaigh et al provide thoughtful, detailed summary of 3 decades of intensive work aimed at developing active, specific immuno-therapies (vaccines) for patients with melanoma. However, as the 20th century draws to a close, the key question is: Can any vaccine be considered an effective therapy for patients with melanoma? To rephrase the question: What constitutes proof of efficacy for a melanoma vaccine, and have any vaccines met those criteria? In a word, the answer to the first question is “no.” The answer to the second question, however, requires more elaboration.

Improvements in Tumor Targeting, Survivorship, and Chemoprevention Pioneered by TamoxifenTwenty years ago, antiestrogen therapy with tamoxifen played only a secondary role in breast cancer care. All hopes to cure metastatic breast cancer were still pinned on either the discovery of new cytotoxic drugs or a dose-dense combination of available cytotoxic drugs with bone marrow transplantation. A similar strategy with combination chemotherapy was employed as an adjuvant for primary breast cancer. Simply stated, the goal was to kill the cancer with nonspecific cytotoxic drugs while keeping the patient alive with supportive care. However, medical research does not travel in straight lines, and an alternative approach emerged to solve the problem of controlling tumor growth with minimal side effects: targeted therapy. The approach of using long-term antihormone therapy to control early-stage breast cancer growth would revolutionize cancer care by targeting the tumor estrogen receptor (ER). The success of the strategy would contribute to a decrease in the national mortality figures for breast cancer. More importantly, translational research that targeted the tumor ER with a range of new antiestrogenic drugs would presage the current fashion of blocking survival pathways for the tumor by developing novel targeted treatments. But a surprise was in store when the pharmacology of "antiestrogens" was studied in detail: The nonsteroidal "antiestrogens" are selective ER modulators—ie, they are antiestrogens in the breast, estrogens in the bone—and they lower circulating cholesterol levels. This knowledge would establish a practical approach to breast cancer chemoprevention for women at high risk (tamoxifen) and low risk (raloxifene).

Cancers of the Gallbladder and Biliary DuctsDr. Yee and his colleagues have offered a comprehensive overview of the epidemiology, diagnosis, and therapy of both gallbladder carcinoma and cholangiocarcinoma. They correctly note the infrequency of these two neoplasms, with approximately 7,500 cases diagnosed in the United States each year, two-thirds of which are gallbladder cancer. Unfortunately, neither the incidence rate nor prognosis of these neoplasms has changed substantially since biliary tumors were last reviewed in this journal[1]; the median 5-year survival rate has remained at 5%. Some progress has been made, however, in our understanding of the etiology of cancers of the biliary tract, and a body of literature continues to emerge exploring the question of how best to approach screening and prophylaxis in high-risk populations.

Commentary (Cohen): Radiation Therapy for Resectable Colon CancerColon cancer is a major public health problem. The primary treatment is resection. For patients with early-stage disease, surgery results in excellent survival rates. In contrast, patients with locally advanced tumors arising in "anatomically immobile" segments of large bowel have a less satisfactory outcome, in part secondary to compromised surgical clearance. Patterns-of-failure analyses suggest that for tumors that invade adjacent organs, exhibit perforation or fistula, or are subtotally resected, local failure rates exceed 30%. Multiple single-institution retrospective studies have shown improved local control and possibly survival with the addition of external irradiation and/or intraoperative radiation. In contrast, a recent Intergroup trial failed to show any benefit by the addition of adjuvant radiation therapy combined with chemotherapy. Interpretation of this trial's results is handicapped by low patient accrual. With the advent of novel and more effective systemic therapies for metastatic colon cancer, current and future clinical research will address the efficacy of these agents in the adjuvant setting. Adjuvant radiation therapy should be considered in patients with colon cancer at high risk for local failure.

Speech and Swallowing Rehabilitation for Head and Neck Cancer PatientsHead and neck cancer and its treatment frequently cause changes in both speech and swallowing, which affect the patient's quality of life and ability to function in society. The exact nature and severity of the post-treatment changes depend on the location of the tumor, the choice of treatment, and the availability and use of speech and swallowing therapy during the first 3 months after treatment. This paper reviews the literature on speech and swallowing problems in various types of treated head and neck cancer patients. Effective swallowing rehabilitation depends on the inclusion of a video-fluorographic assessment of the patient's oropharyngeal swallow in the post-treatment evaluation. Pilot data support the use of range of motion (ROM) exercises for the jaw, tongue, lips, and larynx in the first 3 months after oral or oropharyngeal ablative surgical procedures, as patients who perform ROM exercises on a regular basis exhibit significantly greater improvement in global measures of both speech and swallowing, as compared with patients who do not do these exercises.

Improving Palliative and Supportive Care in Cancer PatientsTwenty years of research in controlling symptoms such as pain andnausea have shown persistent suboptimal performance by the US oncologysystem. The data suggest that some of the tools of palliative careprograms can improve physical symptoms of seriously ill patients at acost society can afford. To fix these problems will require recognitionof the symptoms or concerns, a system such as an algorithm or careplan for addressing each, measurement of the change, and accountabilityfor the change. Symptom assessment scales such as the EdmontonSymptom Assessment Scale or Rotterdam Symptom Check List work tomake symptoms manifest. Listing symptoms on a problem list is a necessarystep in addressing them. Physical symptoms such as pain can beimproved by use of computer prompts, algorithms, dedicated staff time,team management, or combinations of these strategies. Less concreteproblems such as medically appropriate goal-setting, integrating palliativecare into anticancer care sooner, and informing patients aboutthe benefits and risks of chemotherapy near the end of life require morecomplex solutions. We review what is known about symptom control inoncology, how and why some programs do better, and make suggestionsfor practice. Finally, we suggest a practical plan for using symptomassessment scales, listing the problems, and managing them accordingto algorithms or other predetermined plans.
