The Society of Surgical Oncology surgical practice guidelines focus on the signs and symptoms of primary cancer, timely evaluation of the symptomatic patient, appropriate preoperative evaluation for extent of disease, and role of the surgeon in
Dr. O’Connell has done a remarkablejob of discussingmodalities available for patientswith intermediate- to high-riskfully resected large bowel malignancies.Indeed, the title “Current Statusof Adjuvant Therapy for ColorectalCancer” is an underestimate of thearticle’s contents, as he nicely detailsthe past development of standard-ofcareadjuvant (and neoadjuvant, whenappropriate) treatments as well. As isclearly pointed out in the article, adjuvanttherapy works. Adding fluorouracil(5-FU) with or without radiationto surgery already saves thousandsof lives each year, and the enticing possibilityof throwing newer chemotherapeuticagents (eg, oxaliplatin)and/or targeted therapies (bevacizumab[Avastin]) into the mix makespotential future successes even greater.
Bone metastases are a common feature of many solid cancers, especially those originating from the prostate, breast, lung, kidney, melanoma, and other sites. Up to 80% of patients with these cancers will develop painful bony disease during the course of their disease.
Plastic surgical reconstruction extends the capabilities of surgical and radiation therapy for cancer patients. Resection defects that are large, involve functional structures, aesthetically sensitive areas, and/or are at increased risk for wound healing complications are successfully reconstructed with a wide variety of techniques. Cancer and the complications of cancer treatment can involve virtually any area of the body, and to address every potential circumstance, the breadth of oncologic reconstruction must be extensive. A multidisciplinary team approach is the optimal method of cancer treatment, and plastic surgical reconstruction has become a critical component of that treatment, with the ability to restore form and function to the involved areas.
Gastric cancer is more common than esophageal cancer in Western countries but is less fatal. More than 21,130 new cases of gastric cancer will be diagnosed in the United States in the year 2009, with 10,620 deaths expected. Worldwide, gastric cancer represents approximately 930,000 new cases and accounts for more than 700,000 deaths. The incidence and mortality of gastric cancer have been declining in most developed countries, including the United States; the age-adjusted risk (world estimate) fell 5% from 1985 to 1990.
The autosomal, dominantly inherited multiple endocrine neoplasia (MEN) syndromes provide some of the best examples of the practical application of advancing technology, not only in the detection and treatment of neoplastic disease but also in the understanding of the mechanisms involved in the initiation and progression of malignancies.
Drs. Chandler and Silva providean excellent review ofthe technical aspects of tumorextirpation in their article, “ExtendedTransbasal Approach to Skull BaseTumors.” The authors describe the subtletiesof the approach in a clear andconcise manner. As they note, the extendedtransbasal approach allows forexcellent access, which can be modifiedto meet the specific surgical need.
Because many types of cancers metastasize to the lungs, early detection may affect both tumor staging and treatment planning. On the other hand, it is also important to refrain from subjecting patients to procedures that
The article by Drs. Merrick,Wallner, and Butler providesan excellent overview of issuespertaining to sexual dysfunctionfollowing prostate brachytherapy.The authors were the first to addressthe historical and current problemswith diagnosing sexual dysfunction.They make a strong case for developinga quality-of-life (QOL) instrumentthat is specific for prostatebrachytherapy.
Both fluorouracil (5-FU) and irinotecan (CPT-11 [Camptosar]) have shown activity in metastatic colorectal cancer and are approved for its treatment in the United States. Preclinical experiments in cell cultures and human tumor
Head and neck imaging, in its current form, really began with the development of the computed tomographic (CT) scanner in the late 1970s and early ’80s. Originally, only CT scans of the brain were performed because of constraints on gantry size.
Over the past 15 years, lymphatic mapping and sentinel lymph node biopsy in vulvar, vaginal, and cervical cancers have been explored by gynecologic oncologists around the world. Based on the results of multiple single-institution studies, most in our field are optimistic that these techniques will increase the rates of detection of lymph node metastasis while decreasing the morbidity associated with lymphadenectomy. Large validation studies are currently underway in both the United States and Europe. In this review article, we present the published data on mapping techniques and discuss future considerations for these technologies.
In this article, prognostic data are summarized and a suggested approach for discussing hospice enrollment with patients is presented.
Advances in basic science and clinical medicine in the past few decades have increasingly elevated the profile of personalized medicine, ie, the identification of individual tumor or biologic features that offer targets for therapy.
Dr. Piccirillo presents an interesting concept. Although the knowledge that comorbidity and severity of symptoms have a bearing on the prognosis of a patient with cancer is not new, the attempt to measure this influence and include it into a reproducible staging system is commendable.
Two decades have elapsed since publication of the first papers describing the examination of the pancreas via the stomach and the duodenum using an ultrasound probe fixed to an endoscope tip. Initial attempts to image the pancreas in this fashion proved difficult and frustrating, but they were promising enough that instrument makers and gastrointestinal endoscopists persisted in developing increasingly effective devices.
While the multifunctional role of steroid hormones in prostate cancer and men’s health was recognized early, the apparent clinical benefit afforded by ADT tipped the scales in favor of androgen deprivation in men with advanced prostate cancer.
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 Prostate Cancer Intervention Versus Observation Trial (PIVOT) is a randomized trial designed to determine whether radical prostatectomy or expectant management provides superior length and quality of life for men with clinically localized prostate cancer. Conducted at Department of Veterans Affairs and National Cancer Institute medical centers, PIVOT will enroll over 1,000 individuals less than 75 years of age. The primary study end point is all-cause mortality. Secondary outcomes include prostate cancer- and treatment-specific morbidity and mortality, health status, predictors of disease-specific outcomes, and cost-effectiveness. Within the first 3 years of enrollment, over 400 men have been randomized. Early analysis of participants' baseline characteristics indicate that enrollees are representative of men diagnosed with clinically localized prostate cancer throughout the United States. Therefore, results of PIVOT will be generalizable. These results are necessary in order to determine the preferred therapy for clinically localized prostate cancer. [ONCOLOGY 11(8):1133-1143, 1997]
Anemia is a widely prevalent complication among cancer patients. At the time of diagnosis, 30% to 40% of patients with non-Hodgkin lymphoma or Hodgkin lymphoma and up to 70% of patients with multiple myeloma are anemic; rates are higher among persons with myelodysplastic syndromes. Among patients with solid cancers or lymphomas, up to half develop anemia following chemotherapy. For almost 2 decades, erythropoiesis-stimulating agents (ESAs) were the primary treatment for cancer-related anemia. However, reassessments of benefits and risks of ESAs for cancer-associated anemia have occurred internationally. We reviewed guidelines and notifications from regulatory agencies and manufacturers, reimbursement policies, and utilization for ESAs in the cancer and chronic kidney disease settings within the United States, Europe, and Canada. In 2008 the US Food and Drug Administration (FDA) restricted ESAs from cancer patients seeking cure. Reimbursement is limited to hemoglobin levels < 10 g/dL. In the United States, ESA usage increased 340% between 2001 and 2006, and decreased 60% since 2007. The European Medicines Agency (EMEA) recommended that ESA benefits do not outweigh risks. In Europe between 2001 and 2006, ESA use increased 51%; since 2006, use decreased by 10%. In 2009, Canadian manufacturers recommended usage based on patient preferences. In Canada in 2007, approximately 20% of anemic cancer patients received ESAs, a 20% increase since 2004. In contrast to Europe, where ESA use has increased over time, reassessments of ESA-associated safety concerns in the United States have resulted in marked decrements in ESA use among cancer patients.
