Since the publication of the Revised European-American Classification of Lymphoid Neoplasms in 1994, subsequent updates of the classification of lymphoid neoplasms have been generated through iterative international efforts to achieve broad consensus among hematopathologists, geneticists, molecular scientists, and clinicians. Significant progress has recently been made in the characterization of malignancies of the immune system, with many new insights provided by genomic studies. They have led to this proposal. We have followed the same process that was successfully used for the third and fourth editions of the World Health Organization Classification of Hematologic Neoplasms. The definition, recommended studies, and criteria for the diagnosis of many entities have been extensively refined. Some categories considered provisional have now been upgraded to definite entities. Terminology for some diseases has been revised to adapt nomenclature to the current knowledge of their biology, but these modifications have been restricted to well-justified situations. Major findings from recent genomic studies have impacted the conceptual framework and diagnostic criteria for many disease entities. These changes will have an impact on optimal clinical management. The conclusions of this work are summarized in this report as the proposed International Consensus Classification of mature lymphoid, histiocytic, and dendritic cell tumors.

BACKGROUND: For patients with peripheral T-cell lymphoma (PTCL), outcomes using frontline treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapy are typically poor. The ECHELON-2 study demonstrated that brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP) exhibited statistically superior progression-free survival (PFS) per independent central review and improvements in overall survival versus CHOP for the frontline treatment of patients with systemic anaplastic large cell lymphoma or other CD30-positive PTCL.PATIENTS AND METHODS: ECHELON-2 is a double-blind, double-dummy, randomized, placebo-controlled, active-comparator phase III study. We present an exploratory update of the ECHELON-2 study, including an analysis of 5-year PFS per investigator in the intent-to-treat analysis group.RESULTS: A total of 452 patients were randomized (1 : 1) to six or eight cycles of A+CHP (N = 226) or CHOP (N = 226). At median follow-up of 47.6 months, 5-year PFS rates were 51.4% [95% confidence interval (CI): 42.8% to 59.4%] with A+CHP versus 43.0% (95% CI: 35.8% to 50.0%) with CHOP (hazard ratio = 0.70; 95% CI: 0.53-0.91), and 5-year overall survival (OS) rates were 70.1% (95% CI: 63.3% to 75.9%) with A+CHP versus 61.0% (95% CI: 54.0% to 67.3%) with CHOP (hazard ratio = 0.72; 95% CI: 0.53-0.99). Both PFS and OS were generally consistent across key subgroups. Peripheral neuropathy was resolved or improved in 72% (84/117) of patients in the A+CHP arm and 78% (97/124) in the CHOP arm. Among patients who relapsed and subsequently received brentuximab vedotin, the objective response rate was 59% with brentuximab vedotin retreatment after A+CHP and 50% with subsequent brentuximab vedotin after CHOP.CONCLUSIONS: In this 5-year update of ECHELON-2, frontline treatment of patients with PTCL with A+CHP continues to provide clinically meaningful improvement in PFS and OS versus CHOP, with a manageable safety profile, including continued resolution or improvement of peripheral neuropathy.

Background Despite the progress of research and treatment for breast cancer, still up to 30% of the patients afflicted will develop distant disease. Elongation of survival and maintaining the quality of life (QoL) become pivotal issues guiding the treatment decisions. One possible approach to optimise survival and QoL is the use of patient-reported outcomes (PROs) to timely identify acute disease-related burden. We present the protocol of a trial that investigates the effect of real-time PRO data captured with electronic mobile devices on QoL in female breast cancer patients with metastatic disease. Methods This study is a randomised, controlled trial with 1:1 randomisation between two arms. A total of 1000 patients will be recruited in 40 selected breast cancer centres. Patients in the intervention arm receive a weekly request via an app to complete the PRO survey. Symptoms will be assessed by study-specific optimised short forms based on the EORTC QLQ-C30 domains using items from the EORTC CAT item banks. In case of deteriorating PRO scores, an alarm is sent to the treating study centre as well as to the PRO B study office. Following the alarm, the treating breast cancer centre is required to contact the patient to inquire about the reported symptoms and to intervene, if necessary. The intervention is not specified and depends on the clinical need determined by the treating physician. Patients in the control arm are prompted by the app every 3 months to participate in the PRO survey, but their response will not trigger an alarm. The primary outcome is the fatigue level 6 months after enrolment. Secondary endpoints include among others hospitalisations, use of rescue services and overall QoL. Discussion Within the PRO B intervention group, we expect lower fatigue levels 6 months after intervention start, higher levels of QoL, less unplanned hospitalisations and less emergency room visits compared to controls. In case of positive results, our approach would allow a fast and easy transfer into clinical practice due to the use of the already nationwide existing IT infrastructure of the German Cancer Society and the independent certification institute OnkoZert.

CD26/Dipeptidyl Peptidase IV (DPPIV) is a 110-kDa glycoprotein that is expressed on numerous cell types and has multiple biological functions. A key facet of CD26/DPPIV biology is its enzymatic activity and its physical and functional interaction with other molecules. The substrates of CD26/DPPIV are proline-containing peptides and include growth factors, chemokines, neuropeptides, and vasoactive peptides. DPPIV plays an important role in immune regulation, signal transduction, and apoptosis. Furthermore, CD26 appears to play an important role in tumor progression. In the present review, we summarize key aspects of CD26/DPPIV involvement in tumor biology and its potential role in cancer development and behavior.

BACKGROUND: The current study was performed to determine the maximum tolerated dose (MTD), toxicity, and outcome of infusional 5 bromo-2'-deoxyuridine (bromodeoxyuridine; BUdR) given with accelerated fractionation whole brain radiation therapy (WBRT) after chemotherapy for the treatment of primary central nervous system lymphoma (PCNSL). METHODS: Twelve patients with untreated and histologically confirmed PCNSL were entered on the study between 1994 and 1996. Chemotherapy was comprised of one course of IDHAP plus high-dose methotrexate (HD-MTX). IDHAP is comprised of idarubicin at a dose of 1.5 mg/m(2)/day x 4 days intravenously by continuous infusion (i.v. CI), dexamethasone at a dose of 40 mg i.v. on Days 1-5, cytosine arabinoside at a dose of 2000 mg/ m(2) i.v. on Day 5 after cisplatin, and cisplatin at a dose of 25 mg/m(2)/day x 4 days i.v. CI. HD-MTX was given at a dose of 3.5 g/m(2) i.v. between Day 10 and Day 14 after IDHAP. BUdR was given as an i.v. CI over 48 hours, 2-3 days prior to WBRT and then weekly during WBRT. Dose escalation started at 1.5 g/m(2)/day for Cohort 1 with subsequent increments of 0.3 g/m(2)/day. The WBRT dose was 45 grays (Gy) at a dose of 1.5 Gy twice a day, 5 days per week. Neurocognitive testing was performed before, during, and after treatment. RESULTS: Nine of 12 patients entered on the study received BUdR. One of 3 patients in Cohort 1 developed leukoencephalopathy (LEP), a dose-limiting toxicity (DLT), within 2 months of the completion of therapy. Therefore, the next cohort received the same dose level. Because no toxicity was observed in Cohort 2, the third cohort received a BUdR dose of 1.8 g /m(2)/day. Shortly after completing enrollment in Cohort 3, 3 more patients developed LEP, including 2 from Cohort 1 who had received a dose of 1.5 g/m(2)/day. Thus, DLT occurred at a dose of 1.5 g/m(2)/day, the starting level in the current study. As a result, the trial was stopped. Eight of 12 patients achieved a complete response, 3 achieved a partial response, and 1 patient died before response assessment. CONCLUSIONS: Hyperfractionated WBRT with concurrent BUdR after chemotherapy was found to result in modest disease control but has unacceptable neurotoxicity. Cancer
