Occult distant micrometastasis at the time of radical cystectomy leads predominantly to distant failures in patients with locally advanced muscle-invasive transitional cell carcinoma of the bladder. Cisplatin-based combination chemotherapy enhances survival in patients with metastatic urothelial cancer. Studies evaluating adjuvant chemotherapy have been limited by inadequate statistical power. However, randomized clinical trials have demonstrated a survival benefit for neoadjvuant cisplatin-based combination chemotherapy, which should be considered a standard of care. In addition, neoadjuvant therapy may assist in the rapid development of novel systemic therapy regimens, since pathologic complete remission appears to be a powerful prognostic factor for long-term outcomes. Patients who are either unfit for or refuse radical cystectomy may benefit from neoadjuvant chemotherapy with or without radiation to enable bladder preservation.
In February 21, I presented testimony on behalf of the Society before the Senate Labor and Human Resources Committee during a hearing on Food and Drug
The article by Bhatia and colleagues focuses on the treatment of patients with metastatic melanoma using standard therapies, but it also includes a brief outline of recent treatment approaches using investigational agents. In addition, the authors describe prognostic factors for metastatic melanoma, highlighting the impact of the extent of tumor and the site of metastasis (eg, soft-tissue vs visceral metastases) on survival.
A 60-year-old man presented with lower limb claudication and a painful mass on his left buttock. Physical examination revealed a firm round mass, fixed to deep planes. A biopsy was performed and revealed a chordoma.
In this review, we critically analyze clinical trials that were specifically designed for the very elderly, and we discuss the challenges encountered by investigators who are conducting studies in this patient population. We conclude by proposing an algorithm to help clinicians determine the optimal therapeutic strategy for treatment of DLBCL in very elderly patients.
The review by Gururangan andFriedman takes an interestingand informative approach to pediatricbrain tumors in emphasizingthe possible biologic bases for chemotherapyfailure in these neoplasmsin general, and focusing on newer, asyet largely unproven, strategies employing“biologic” therapies to circumventsuch mechanisms of tumor resistance.Many of these newer treatment strategiesare drawn from the work of theauthors and others in the field of adultmalignant gliomas. To date, minimalprogress has been achieved in improvingoutcome for children with malignantsupratentorial gliomas andbrainstem tumors. Hopefully, these newstrategies will have significant benefitin pediatric as well as adult patients.
APBI is a technique that offers women with early-stage breast cancer a choice. The preponderance of evidence supports the efficacy and safety of this technique, and it should continue to be offered to appropriately selected patients on and off protocol.
Given the current rate of progress in this field, it may not be completely unlikely that women with hormone receptor–positive breast cancer will be cured of this disease in the foreseeable future.
This review will focus on properties of cancer stem cells; will compare and contrast the cancer stem cell model with the clonal evolution model of tumorigenesis; will discuss the role of cancer stem cells in the development of resistance to chemotherapy; and will review the therapeutic implications and challenges of targeting cancer stem cells, with an assessment of the potential such an approach holds for improving outcomes for patients with cancer.
Most physicians are less aware of clinical presentations of the various heavy chain diseases, due in great part to their low incidence and highly variable clinical course. Heavy chain diseases are rare lymphoproliferative B-cell disorders whose hallmark is the accumulation and secretion of truncated constant heavy chains without the associated light chains.
Conventional histopathologic evaluation of bladder cancer, encompassing tumor grade and stage, is inadequate to accurately predict the behavior of most bladder tumors. Intense research efforts are under way to identify and
In this article, we summarize the systemic therapies now available for melanoma, with a focus on the recently approved agents for cutaneous melanoma; discuss important considerations in selecting a treatment from the available options; and highlight some of the promising investigational approaches for this disease.
The panel concludes its discussion with key takeaways on unmet needs and evolving treatment paradigms in relapsed/refractory multiple myeloma.
Case History: 60-year-old man with mild right side abdominal discomfort and hepatomegaly found to have large right renal mass during CT scan.
Thanks to the widespread use of highly active antiretroviral therapy (HAART), AIDS patients continue to live longer after their initial diagnosis.
Prevention of CNS seeding early in the metastatic disease course using drugs with both intra- and extracranial activity will be crucial to improving outcomes in patients with breast cancer brain metastases.
Surgical resection of isolated pulmonary metastases has been incorporated into the management of cancer for more than 70 years. However, many questions still remain concerning indications, technique, and efficacy for this approach.
A 70-year-old man presented at our institution for a second opinion regarding diagnosis of a urinary bladder mass. He had a 3-year history of worsening urinary incontinence and urgency, for which he had undergone colonoscopy, as well as testing for prostate issues; all test results were negative.
The purpose of this article is to present an updated set of American College of Radiology consensus guidelines formed from an expert panel on the appropriate use of radiation therapy in postprostatectomy prostate cancer.
In the United States, approximately 20% of patients with colorectal cancer present with distant metastasis at diagnosis. In 25% of cases, the peritoneal cavity is the only site of metastatic disease, which is not indicative of a generalized systemic disease, as is the case with lung or liver metastases.
While organ preservation with nonextirpative surgery, radiotherapy,and frequently, chemotherapy has become a favored strategy in thetreatment of many cancers, bladder preservation for patients with invasivedisease remains controversial. The standard treatment for muscleinvasivebladder cancer in the United States is still radical cystectomywith pelvic lymph node dissection. An alternative to cystectomy ismultimodality bladder preservation with thorough transurethral resection,chemotherapy, and radiation therapy. This review will addressissues raised by a multimodality approach for the treatment of invasivebladder cancer.
Colorectal cancer is the second most common cause of cancerrelateddeath in the United States. Approximately 30% to 40% of patientswith colorectal cancer have locoregionally advanced or metastaticdisease on presentation and cannot be cured with surgical therapy.After many years without significant change, systemic therapy forcolorectal cancer is rapidly evolving. The past decade has seen the introductionof new chemotherapeutic agents such as irinotecan(Camptosar), oxaliplatin (Eloxatin) and the oral 5-FU prodrugcapecitabine (Xeloda). Combination studies of these new agents withthe standard 5-FU/leucovorin have extended median survival in patientswith advanced colorectal cancer for up to 21 months. In addition,targeted agents with activity in colorectal cancer have emergedand are promising. This article reviews the current treatment recommendationsfor patients who present with advanced colorectal cancer.Survival in patients with advanced colorectal cancer is on a positivetrajectory. The hope that some patients with advanced disease will belong-term survivors (even without surgery) appears to be within therange of possibility.
Prevention of CNS seeding early in the metastatic disease course using drugs with both intra- and extracranial activity will be crucial to improving outcomes in patients with breast cancer brain metastases.
Up to 25% of patients diagnosed with breast cancer have tumors that overexpress HER2. HER2-positive breast cancer is highly proliferative, difficult to treat, and confers a poor prognosis. The advent of the anti-HER2 monoclonal antibody trastuzumab (Herceptin) has markedly altered the clinical course of both early and advanced HER2-driven breast cancer. Despite the use of trastuzumab, however, patients with HER2-positive breast cancer still experience disease progression. Overcoming that resistance to therapy is our next challenge. This review examines the current understanding of HER2 biology, the mechanisms of action of and resistance to trastuzumab, as well as new therapies on the horizon.
Xerostomia is a permanent and devastating sequela of head and neckirradiation, and its consequences are numerous. Pharmaceutical therapyattempts to preserve or salvage salivary gland function through systemicadministration of various protective compounds, most commonlyamifostine (Ethyol) or pilocarpine. When these agents are ineffective orthe side effects too bothersome, patients often resort to palliative care, forexample, with tap water, saline, bicarbonate solutions, mouthwashes, orsaliva substitutes. A promising surgical option is the Seikaly-Jha procedure,a method of preserving a single submandibular gland by surgicallytransferring it to the submental space before radiotherapy. Improved radiationtechniques, including intensity-modulated radiotherapy andtomotherapy, allow more selective delivery of radiation to defined targetsin the head and neck, preserving normal tissue and the salivary glands.Acupuncture may be another option for patients with xerostomia. All ofthese therapies need to be further studied to establish the most effectiveprotocol to present to patients before radiotherapy has begun.
About 30,000 new cases of thyroid cancer are diagnosed annually in the United States.[1] The incidence among men has risen more dramatically than any other malignancy in recent years (2.4% annual increase).[2] Thyroid cancers arise from one of two cell types, namely follicular and parafollicular cells.
Management of ductal carcinoma in situ (DCIS) commonly involves excision, radiotherapy, and hormonal therapy. Radiotherapy is employed for local control in breast conservation. Evidence is evolving for several radiotherapy techniques exist beyond standard whole-breast irradiation.
This management guide covers the diagnosis and treatment of early-stage breast cancers, including lobular carincoma in situ (LCIS), ductal carcinoma in situ (DCIS), and both noninvasive and invasive disease.
