The University of Colorado Health Sciences Center holds weekly second opinion conferences focusing on cancer cases that represent most major cancer sites. Patients seen for second opinions are evaluated by an oncologist.
End-of-life care is challenging for even the most seasoned oncologist. Here are five suggestions that can help you better navigate this difficult but critical part of your work.
Proteasome inhibition is a novel, targeted approach in cancertherapy. Both natural and synthetic proteasome inhibitors selectivelypenetrate cancer cells, disrupting the orderly destruction of key regulatoryproteins involved in tumorigenesis and metastasis. Disrupting theorderly destruction of regulatory proteins causes an imbalance of theseproteins within the cell, which interferes with the systematic activationof signaling pathways required to maintain tumor cell growth and survival;therefore, cellular replication is inhibited and apoptosis ensues.
The article by Bisseck and colleagueshighlights an importantissue encountered increasinglyby physicians-melanoma in childrenand adolescents. The incidence andmortality of melanoma continues torise.[1] It is now the fifth most commoncancer in men and the seventhmost common cancer in women. Inour practice at the Johns HopkinsMelanoma Center, we have treated agrowing number of children and adolescentswith melanoma, includingmany with stage III disease identifiedby sentinel node technology, similarto that described by Bisseck andcolleagues.
This review addresses the rationale and evidence for-and the challenges, cost implications, and future development of-proton therapy as an important part of the treatment strategy in Hodgkin lymphoma.
After a review of the published literature, the panel voted on three variants to establish best practices for the utilization of imaging, radiotherapy, and chemotherapy after primary surgery for early-stage endometrial cancer.
In their recent commentary (Oncology 23:639-641, 2009), Labriola and colleagues reviewed the data on “natural” hormone replacement and breast cancer risk. The “natural” agents were bioidentical and phytoestrogen supplements to manage vasomotor symptoms in breast cancer patients.
In this case report, we discuss the presentation, workup, and therapeutic management of a 40-year-old man who presented with borderline resectable, periampullary pancreatic cancer and underwent a margin-negative resection following neoadjuvant chemoradiotherapy.
Lung cancer is estimated to be the second most commonly diagnosed cancer in both men and women in 2006, and the leading cause of cancer mortality. Non-small-cell lung cancer represents the majority of such cases. Most of these patients have locally advanced disease at presentation and are not eligible for curative resection. For the minority of patients who are technically resectable at presentation, lobectomy or pneumonectomy and pathologic mediastinal nodal staging offer the best overall survival. The high rate of comorbid medical illness and poor baseline pulmonary function in this population, however, make many such early-stage patients medically inoperable. For these patients, conventional single-modality radiotherapy has been the primary definitive treatment option, as discussed in part 1 of this article, which appeared in last month's issue. Numerous retrospective reports demonstrate long-term disease-free and overall survival data that are modestly superior to that expected after observation, but both local and distant failure continue to be significant risks. Investigation of radiotherapy dose escalation is ongoing, in an effort to improve local control while maintaining minimal toxicity. Additionally, emerging evidence suggests that new modalities, such as stereotactic radiosurgery and radiofrequency ablation, may also be potentially curative treatment alternatives. These modalities are addressed in part 2.
Decades of experience now exist to support the use of chemoradiotherapy in the treatment of muscle-invasive bladder cancer. Chemoradiotherapy for T1 tumors that recur following bacillus Calmette-Guérin therapy is promising and provides an important curative alternative for those unable or unwilling to undergo radical cystectomy.
It is with great sadness that the Angiogenesis Foundation reflects on the passing of Dr. Judah Folkman, founder and pioneer of the field of angiogenesis research.
Despite a decreasing incidence in the United States, small-cell lung cancer (SCLC) remains a major clinical problem, with approximately 30,000 new cases each year. The diagnosis of SCLC is usually not difficult. The Veterans Administration Lung Study Group (VALSG) staging system is less accurate than the American Joint Committee of Cancer tumor-node-metastasis (TNM) system (7th edition) at predicting survival in SCLC, especially in lower stage disease. Surgery has not played a major part in the management of SCLC, but emerging data suggest that resection may have a role in earlier stage disease. While the frontline treatment of SCLC has not changed significantly in the past decade, newer agents that are currently being investigated provide hope for better treatment of relapsed/refractory disease for the future.
CancerNetwork® spoke with Dr. William Wood on the clinical risk of chemotherapy in early breast cancer.
This article represents the consensus opinion of an expert panel and may be used to inform clinical recommendations in vaginal cancer management.
A 69-year-old man presented in the urology clinic for evaluation of bilateral renal masses, discovered incidentally during routine exams for follow-up of his chronic kidney disease.
Burkitt lymphoma (BL) is a unique B-cell lymphoma characterized by a high proliferation rate and cytogenetic changes related to c-myc proto-oncogene overexpression. Burkitt lymphoma is a highly aggressive B-cell lymphoma that is most frequently seen in children and young adults in endemic areas.
With better disease definition, staging, and monitoring, treatment of extranodal NK/T-cell lymphoma is becoming more rational. A large proportion of patients with localized nasal disease may enjoy prolonged disease-free survival. On the other hand, early HSCT or novel therapy may be recommended for aggressive extranasal disease.
Uracil and tegafur (in a molar ratio of 4:1 [UFT]) plus calcium folinate comprise the components of the oral agent, Orzel, which appears to have activity comparable to intravenously administered 5-fluorouracil. This article
The field of hematopoietic stem cell transplantation is evolving rapidly. Observations made in the laboratory can now be swiftly translated into clinical trials. The role of hematopoietic stem cell transplantation in older patients, the appropriate use of
Drs. Rini and Bukowski do an excellent job of updating and commenting on the rapidly evolving field of therapy for metastatic renal cell carcinoma (RCC).
Chromosomal changes have been identified early in the disease process in cutaneous T-cell lymphoma (CTCL): both losses and gains of chromatin have been found on several chromosomes. The extent of chromosomal aberrations increases with disease stage and in more aggressive subtypes of the disorder. Changes in specific genes, such as NAV3, have been characterized in patients with CTCL, and may produce a proliferation advantage for affected cells. In addition, the expression of some genes can discriminate between controls and patients with CTCL. Therefore, the over- or under-expression of certain genes may be of diagnostic and pathogenic relevance in this disease, and may allow the development of selective treatments.
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.
Colorectal 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.
In the absence of a clear understanding of the underlying biologic heterogeneity, the etiology of the different heavy chain diseases (HCDs) should be taken into consideration when treatment decisions are made. Extrapolation from related conditions, such as aggressive lymphomas (in γ-HCD) and CLL (in μ-HCD), suggests that novel and targeted therapies may be effective in the management of these rare diseases.
The classification of diffuse large B-cell lymphoma into three distinct molecular diseases--germinal center B-cell–like subtype, an activated B-cell–like subtype, and a primary mediastinal B-cell lymphoma subtype--has laid the foundation for the development of new agents and novel strategies that target individual subtypes.
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.
Our better understanding of the complex interaction of multiple myeloma (MM) cells with their bone marrow microenvironment and the signaling pathways that are dysregulated in this process has resulted in a dramatic increase in the therapeutic agents available for this disease. A number of these new agents have demonstrated significant activity in patients with MM. Over the past 5 years, three drugs have received approval from the US Food and Drug Administration for therapy in MM—bortezomib, thalidomide, and lenalidomide. To date, the choice of therapy for MM is not individualized according to the biologic characteristics of the disease, but future studies should enable us to identify patients who may benefit most from certain therapeutic interventions, and thus develop individualized therapy for MM. In this review, we will present some of the treatment algorithms currently developed for patients with MM and focus on established advances in therapy, specifically with thalidomide, bortezomib, and lenalidomide. We will also discuss some of the emerging novel therapeutic agents showing promise in phase I/II clinical trials in MM.
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.
From March 1996 to March 1998, 106 patients with untreated metastatic breast cancer (MBC) were treated with docetaxel (Taxotere) (100 mg/m²) and doxorubicin (75 mg/m²) on an alternating cycle-by-cycle (doxorubicin, docetaxel, doxorubicin, etc) or sequential (four cycles of docetaxel, then four cycles of doxorubicin) basis, every 3 weeks, for a maximum of eight cycles.
High-dose therapy (HDT) with peripheral blood stem cell transplantation is a treatment option for patients with advanced follicular, marginal, and mantle cell lymphoma. In this setting, frequent contamination of peripheral blood stem cell harvests by
