Abstract
INTRODUCTION We examined patient characteristics, treatments, and outcomes of patients with transformed mycosis fungoides (tMF) from COMPLETE: a large, multicenter, prospective cohort study of peripheral T-cell lymphoma patients in the United States. METHODS Patients with tMF were enrolled in COMPLETE at the time of transformation. For this analysis, we identified patients with tMF with completed baseline, treatment, and follow-up records. Median survival was assessed using Kaplan-Meier methodology. RESULTS Of the 499 patients enrolled in COMPLETE, 17 had tMF. Median age was 61; 53% were male, 9 had elevated lactate dehydrogenase, and 9 had lymph node involvement. Approximately one-quarter of the patients were African American and 47% had CD30+ disease. Median time to transformation was 53 months. All patients received systemic therapy, with 19% receiving concomitant radiotherapy. Most patients (87%) received single agents, including liposomal doxorubicin, pralatrexate, and gemcitabine. Eight patients (50%) had reported responses to therapy. Median survival was 18 months. One- and 2-year survival rates were 56% and 44%, respectively. CONCLUSIONS tMF often expresses CD30 and presents with lymph node involvement. Responses have been seen with single agents, but survival remains poor. Novel treatment approaches are urgently needed to improve outcomes.

Abstract
BACKGROUND Outcomes for patients with peripheral T-cell lymphoma (PTCL) who fail to achieve complete response (CR) or relapse after front-line therapy are poor with lack of prospective outcomes data. OBJECTIVES COMPLETE is a prospective registry of 499 patients enrolled at academic and community sites in the United States detailing patient demographics, treatment and outcomes for patients with aggressive T cell lymphomas. We report results for patients with primary refractory and relapsed disease. METHODS Primary refractory disease was defined as an evaluable best response to initial treatment (induction ± maintenance or consolidation/transplant) other than CR, and included a partial response, progressive disease, or no response/stable disease. Relapsed disease was defined as an evaluable best response to initial treatment of CR, followed by disease progression at a later date, irrespective of time to progression. Patients were included in the analysis if initial treatment began within 30 days of enrollment and treatment duration was ≥4 days. RESULTS Of 420 evaluable patients, 97 met the definition for primary refractory and 58 with relapsed disease. In the second-line setting, relapsed patients received single-agent therapies more often than refractory patients (52 vs. 28%; p = 0.01) and were more likely to receive single-agent regimens (74 vs. 53%; p = 0.03). The objective response rate to second-line therapy was higher in relapsed patients (61 vs. 40%; p = 0.04) as was the proportion achieving a CR (41 vs. 14%; p = 0.002). Further, relapsed patients had longer overall survival (OS) compared to refractory patients, with a median OS of 29.1 versus 12.3 months. CONCLUSIONS Despite the availability of newer active single agents, refractory patients were less likely to receive these therapies and continue to have inferior outcomes compared to those with relapsed disease. PTCL in the real world remains an unmet medical need, and improvements in front-line therapies are needed.

Abstract
BACKGROUND The role of autologous stem cell transplantation (ASCT) in the first complete remission (CR1) of peripheral T-cell lymphomas (PTCLs) is not well defined. This study analyzed the impact of ASCT on the clinical outcomes of patients with newly diagnosed PTCL in CR1. METHODS Patients with newly diagnosed, histologically confirmed, aggressive PTCL were prospectively enrolled into the Comprehensive Oncology Measures for Peripheral T-Cell Lymphoma Treatment (COMPLETE) study, and those in CR1 were included in this analysis. RESULTS Two hundred thirteen patients with PTCL achieved CR1, and 119 patients with nodal PTCL, defined as anaplastic lymphoma kinase-negative anaplastic large cell lymphoma, angioimmunoblastic T-cell lymphoma (AITL), or PTCL not otherwise specified, were identified. Eighty-three patients did not undergo ASCT, whereas 36 underwent consolidative ASCT in CR1. At the median follow-up of 2.8 years, the median overall survival was not reached for the entire cohort of patients who underwent ASCT, whereas it was 57.6 months for those not receiving ASCT (P = .06). ASCT was associated with superior survival for patients with advanced-stage disease or intermediate-to-high International Prognostic Index scores. ASCT significantly improved overall and progression-free survival for patients with AITL but not for patients with other PTCL subtypes. In a multivariable analysis, ASCT was independently associated with improved survival (hazard ratio, 0.37; 95% confidence interval, 0.15-0.89). CONCLUSIONS This is the first large prospective cohort study directly comparing the survival outcomes of patients with nodal PTCL in CR1 with or without consolidative ASCT. ASCT may provide a benefit in specific clinical scenarios, but the broader applicability of this strategy should be determined in prospective, randomized trials. These results provide a platform for designing future studies of previously untreated PTCL.

Abstract
BACKGROUND Long-term survival in patients with aggressive peripheral T-cell lymphoma (PTCL) is generally poor, and there currently is no clear consensus regarding the initial therapy used for these diseases. Herein, the authors analyzed treatment patterns and outcomes in a prospectively collected cohort of patients with a new diagnosis of nodal PTCL in the United States. METHODS Comprehensive Oncology Measures for Peripheral T-cell Lymphoma Treatment (COMPLETE) is a prospective multicenter cohort study designed to identify the most common prevailing treatment patterns used for patients newly diagnosed with PTCL in the United States. Patients with nodal PTCL and completed records regarding baseline characteristics and initial therapy were included in this analysis. All statistical tests were 2-sided. RESULTS Of a total of 499 patients enrolled, 256 (51.3%) had nodal PTCL and completed treatment records. As initial therapy, patients received doxorubicin-containing regimens (41.8%), regimens containing doxorubicin plus etoposide (20.9%), other etoposide regimens (15.8%), other single-agent or combination regimens (19.2%), and gemcitabine-containing regimens (2.1%). Survival was found to be statistically significantly longer for patients who received doxorubicin (log-rank P = .03). After controlling for disease histology and International Prognostic Index, results demonstrated a trend toward significance in mortality reduction in patients who received doxorubicin compared with those who did not (hazard ratio, 0.71; 95% confidence interval, 0.48-1.05 [P = .09]). CONCLUSIONS To the authors' knowledge, there is no clear standard of care in the treatment of patients with PTCL in the United States. Although efforts to improve frontline treatments are necessary, anthracyclines remain an important component of initial therapy for curative intent.

Abstract
The objective of this study was to estimate health care-resource utilization in head and neck cancer (HNC) patients. This was a prospective, longitudinal, multicenter, noninterventional study of mucositis in patients receiving radiation with or without chemotherapy for HNC. Mouth and throat soreness and functional impairment were measured using the Oral Mucositis Weekly Questionnaire-HNC. Resource utilization data were obtained from patient interviews and recorded from the patient's medical chart. Seventy-five patients were enrolled from six centers. Fifty (67%) patients received concurrent chemoradiation therapy; 34 (45%) received intensity-modulated radiation therapy. Over the course of treatment, 57 (76%) patients reported severe mouth and throat soreness. Pain and functional impairment because of mouth and throat soreness increased during the course of therapy despite the use of opioid analgesics in 64 (85%) of the patients. Complications of radiation therapy resulted in increased patient visits to physicians, nurses, and nutritionists. Thirty-eight (51%) patients had a feeding tube placed. Twenty-eight patients (37%) were hospitalized, five of whom were hospitalized twice; of the 33 admissions, 10 (30%) were designated as secondary to mucositis by their treating physician. Mean length of hospitalization was 4.9 days (range: 1-16). This study demonstrates that mucositis-related pain and functional impairment is associated with increased use of costly health resources. Effective treatments to reduce the pain and functional impairment of oral mucositis are needed in this patient population.

Abstract
Oral mucositis represents a significant source of morbidity after chemotherapy and radiation therapy. Since infection may have an important role in the pathophysiology of oral mucositis, several antimicrobial agents have been investigated for their efficacy in preventing and treating this disease. We sought to establish the weight of evidence for antimicrobial treatment and identified 31 prospectively designed clinical trials of which 13 reported some benefit and 15 did not. No clear pattern was identified regarding patient type, cancer treatment, or type of antimicrobial agent used, and inconsistent assessment of oral mucositis made comparison of outcomes difficult. Newer drugs, such as the topical antimicrobial peptide iseganan HCl initially showed promise in reducing mucositis and the related oral pain but the results of a phase 3 trial were disappointing and the line of enquiry was abandoned altogether. Hence, there is a need to better understand the role of the microflora in the cause of oral mucositis if an antimicrobial agent for prevention and treatment of this disease is to be developed.

Abstract
BACKGROUND AND PURPOSE To determine the frequency of mucositis and associated outcomes in patients receiving radiotherapy (RT) for head and neck cancer through a systematic review of recently published literature. MATERIALS AND METHODS According to the study protocol, databases were searched for randomized clinical trials (English only, 1996-1999) of patients with head and neck cancer receiving RT with or without chemotherapy that reported one or more outcomes of interest. RESULTS Thirty-three studies (n=6181 patients) met inclusion criteria. Mucositis was defined using a variety of scoring systems. The mean incidence was 80%. Over one-half of patients (56%) who received altered fractionation RT (RT-AF) experienced severe mucositis (grades 3-4) compared to 34% of patients who received conventional RT. Rates of hospitalization due to mucositis, reported in three studies (n=700), were 16% overall and 32% for RT-AF patients. Eleven percent of patients had RT regimens interrupted or modified because of mucositis in five studies (n=1267) reporting this outcome. Data insufficiency or heterogeneity prohibited analysis of mucositis severity and other associated outcomes, such as oral pain, dysphagia and opioid use. CONCLUSIONS Mucositis is a frequent, severe toxicity in patients treated with RT for head and neck cancer. While it appears that mucositis may lead to hospitalization and treatment interruptions, its overall impact on outcomes has not been adequately investigated.

Abstract
Newer treatments for head and neck cancers, including altered fractionation and the use of concomitant radiotherapy and chemotherapy, may provide better local-regional tumor control rates; however, patients may experience more frequent and more severe acute toxicities that result in considerable suffering. Through this study, we sought a better understanding of patients' experiences when undergoing radiotherapy. Personal interviews were conducted with 33 individuals who had received radiotherapy for head and neck cancers. These individuals described their treatment experiences and identified the most troublesome and debilitating side effects of radiotherapy. Overall, lethargy and weakness, dry mouth, mouth sores and pain, taste changes, and sore throat were the most frequently reported troublesome or debilitating side effects. The single most debilitating side effect was oropharyngeal mucositis that was characterized by patients as sore throat, and mouth sores and pain; both negatively affected the patient's ability to eat and drink, causing many patients to experience significant weight loss. Trends toward more aggressive management of head and neck cancers underscore the need for new and effective therapies for oropharyngeal mucositis occurring in patients receiving radiotherapy.

Abstract
Oral Mucositis (OM) is a frequent cause of severe morbidity in patients receiving chemotherapy and/or radiotherapy. The pathophysiology of OM involves direct cytotoxic effects, local inflammatory responses, and alterations in oral microflora. There are currently no approved agents for the prevention or treatment of OM. In this review we briefly describe current knowledge of the pathophysiology, clinical presentation, and management of OM. We then discuss investigational agents being studied in OM with a particular focus on local antimicrobial agents, hemopoietic growth factors, and cytokines. Measures to reduce the incidence of OM and/or alleviate its clinical sequelae should be incorporated into all chemotherapy or radiotherapy studies.

Abstract
Oral mucositis (OM)-related outcomes constituting a meaningful clinical advance in bone marrow transplant patients were considered by an interdisciplinary panel. Meaningful outcomes are essential in product development for OM, a condition without effective prevention or treatment. The most important outcomes to measure, the feasibility of measuring these in a clinical trial, and clinically meaningful differences in these outcomes were determined by the panel. Most important are reduction in oral pain and use of opioid analgesics, improvement in oral intake and quality of life, and reduction of hospitalization duration. Reduction in the severity of OM measured by an objective evaluation of oral mucosa could provide insight regarding the biologic activity of an intervention. Further data are required to define the precise relationship between reduction in visible OM and improvement in outcome. Minimally, clinical trials for OM should assess oral pain, opioid use, oral intake, and include objective assessment of OM.

Abstract
Topical approaches to management of oral mucositis have the advantages of high local concentration and limited or no systemic absorption, reducing the risk of systemic complications. The acceptability of topical therapies in cancer patients has not been evaluated. Thirty-eight transplant patients assessed the acceptability of three formulations (rinse, thin gel, thick gel) of a new compound developed to prevent oral mucositis. The rinse was selected as the most acceptable formulation. The thick gel received the lowest rating. Consistency was a major determinant of overall acceptability. A neutral taste was desirable for most participants. Room temperature of the formulation was rated as completely acceptable. Most participants would be willing to use the rinse or thin gel several times per day, to retain each dose in the oral cavity for up to 5 min, and to swallow it. The support of caregivers may be needed to achieve compliance with such regimens.

Abstract
In recent years, significant improvements have been made in the management of neutropenia and thrombocytopenia and other potentially life-threatening complications of ablative chemotherapy. While these complications are of particular concern to physicians, patients receiving ablative therapy for bone marrow or blood stem cell transplants are often troubled by other side effects such as nausea, vomiting, diarrhea and mouth sores. The purpose of the study was to gain a better understanding of patients' experiences while undergoing a transplant. The same professional medical interviewer conducted in-depth interviews with 38 subjects (10 men, 28 women; mean age 46.9 years) who had received ablative therapy for bone marrow and/or peripheral blood stem cell transplants. Participants were consecutively identified through physician and patient referrals, cancer and BMT patient support groups, and newspaper advertisements. Twenty-eight patients (74%) received autologous stem cell transplants and 10 patients (26%) received allogeneic transplants. Participants reported mouth sores, nausea and vomiting, diarrhea, and fatigue as the most troubling side effects of their transplants. Mouth sores were selected as the single most debilitating side effect (42%), followed by nausea and vomiting (13%). Many patients mentioned that mouth sores made it difficult or impossible to eat (n = 23), swallow (n = 21), drink (n = 17), and/or talk (n = 8). Twenty patients reported pain in the mouth, throat, and/or esophagus. Two-thirds (66%) of patients reported receiving opioid analgesics, most frequently morphine, to relieve oral pain. For many, opioids caused incapacitating side effects, including hallucinations, a feeling of loss of control and a decrease in mental acuity. Patients receiving ablative chemotherapy identify oral mucositis as a significant cause of suffering and morbidity. Effective interventions to alleviate this complication are urgently needed.
