Selected AbstractsPrognostic factors for classifying extranodal NK/T cell lymphoma, nasal type, as lymphoid neoplasiaEUROPEAN JOURNAL OF HAEMATOLOGY, Issue 1 2007Im I. Na Abstract This study evaluated the applicability of prognostic factors commonly used for diagnosis of classical lymphoma outcomes to extranodal NK/T cell lymphoma, nasal type (NTCL). Clinical features and their associations with lactate dehydrogenase (LDH) were evaluated in 70 patients. RLDH was defined as the ratio of LDH to the upper normal limit. RLDH was associated with stage (I,II vs. III,IV), lymph node involvement (LNI), and International Prognostic Index score (<2 vs. ,2). Poor performance status and advanced stage were common in patients with local tumor invasiveness (LTI). LDH level, classified into three levels (low, high, and very high) was associated with survival (P < 0.001). In multivariate analysis, the predictive values of LDH level, B symptom, performance status, and stage remained significant whereas those of LTI and LNI did not. Scoring was performed by weighting each factor with 0.5 or 1.0 according to its hazard ratio. Scores were classified into four groups. Groups with high scores were associated with unfavorable outcomes (P < 0.001). Current study suggests that prognostic factors for NHL may be useful to predict the outcome of NTCL but the model should take LDH level and the prognostic weight of each factor into account. [source] Clinical trial enrollment, patient characteristics, and survival differences in prospectively registered metastatic colorectal cancer patientsCANCER, Issue 20 2009Halfdan Sorbye MD Abstract BACKGROUND: Trial accrual patterns were examined to determine whether metastatic colorectal cancer (mCRC) patients enrolled in trials are representative of a general cancer population concerning patient characteristics and survival. METHODS: A total of 760 mCRC patients referred for their first oncological consideration at 3 hospitals in Scandinavia covering defined populations were registered consecutively during 2003 to 2006. Clinical trial enrollment, patient characteristics, and treatment were recorded prospectively, and the follow-up was complete. RESULTS: Palliative chemotherapy was initiated in 61% of the patients. Approximately one,third (36%) of patients receiving chemotherapy were included in a trial. The main reason for nonparticipation was failed eligibility criteria (69%). The median survival after chemotherapy was 15.8 months for all patients, and 18 months after combination chemotherapy. Trial patients had better prognostic characteristics and significantly longer survival than nontrial patients: 21.3 months versus 15.2 months when receiving combination chemotherapy. Poor performance status was the main reason for giving best supportive care only, and the median survival was then only 2.1 months. The median survival for all 760 nonresectable mCRC patients was 10.7 months. CONCLUSIONS: mCRC patients enrolled into clinical trials differ in characteristics from patients receiving chemotherapy outside protocol and have better survival, even when given the same treatment. Although trial patients have a median survival close to 2 years, survival is lower for all patients receiving chemotherapy and much lower for all patients diagnosed with mCRC. Studies that better accept the heterogeneity of the population with mCRC are needed. Cancer 2009. © 2009 American Cancer Society.

We present the results of treatment of Philadelphia chromosome-negative (Ph,) ALL patients over 55 yr treated in the PETHEMA ALL-96 trial. Patients and methods:,From 1996 to 2006, 33 patients 55 yr with Ph, ALL were included. Induction therapy was vincristine, daunorubicin, prednisone, asparaginase, and cyclophosphamide over 5 weeks. Central nervous system (CNS) prophylaxis involved triple intrathecal (IT) therapy, 14 doses over the first year. Consolidation-1 included mercaptopurine, methotrexate, teniposide and cytarabine, followed by one consolidation-2 cycle similar to the induction cycle. Maintenance consisted of mercaptopurine and methotrexate up to 2 yr in complete remission (CR) with monthly reinduction cycles (vincristine, prednisone and asparaginase) during the first year. Results:,Median (range) age was 65 yr (56,77). Phenotype (30 patients): early-pre-B 7, common/pre-B 18, T 5. Cytogenetics (28 patients): normal 12, complex 10, t(4;11) 2 and other 4. CR was achieved in 19/33 (57.6%) patients, early death occurred in 12 (36.4%) and 2 (6%) were resistant. Overall survival and disease-free survival probabilities (2 yr, 95% CI) were 39% (21%,57%) and 46% (22%,70%), respectively (median follow up of 24 months). Removal of asparaginase and cyclophosphamide from the induction decreased induction death (OR 0.119, CI 95% 0.022,0.637, P = 0.013) and increased survival (20% vs. 52%, P = 0.05). Conclusions:,The prognosis of elderly Ph, ALL patients is poor. In this study, less intensive induction decreased toxic death, allowing delivery of planned consolidation therapy and increased survival probability.

Low-profile second-generation THORP titanium plates combined with soft tissues free flaps (forearm or TRAM) can be used for oromandibular reconstruction in patients with SCC in advanced stage (stage III,IV). Methods. To evaluate long-term stability and possible complications of this reconstructive technique, we recorded, retrospectively, data of 25 patients with posterolateral oromandibular defects after tumor resection collected during a 5-year period. Results. All free flaps were successfully transferred, although eight patients were initially seen with delayed hardware-related reconstructive complications: plate exposure in four patients and plate fracture in four patients. Conclusions. Nowadays, the state-of-the-art treatment for mandibular defects is primary bone reconstruction with bone free flaps, but in selected cases (elderly patients, poor performance status, posterolateral oromandibular defects, soft tissue defects much more important than bone defects) the association with THORP plate-soft tissue free flaps represents a good reconstructive choice. © 2002 Wiley Periodicals, Inc.

Topoisomerase II, (Topo II,) is a marker of cell proliferation and a crucial target for anthracycline cytotoxicity, the mainstay of management employed in AML. We retrospectively investigated the prognostic roles of ,-catenin and topo II, in a cohort of 59 patients with newly diagnosed AML by immunohistochemistry. Aberrant ,-catenin expression was demonstrated in 13 patients (22%), and it was more likely to occur in those with unfavorable karyotypes. Advanced age and poor performance status adversely influenced the achievement of complete remission, while neither aberrant ,-catenin expression nor enhanced topo II, activity did. On multivariate survival analysis, four factors independently predicted a shortened overall survival: aberrant ,-catenin expression, high topo II, activity, poor-risk cytogenetics, and presence of at least one comorbidity factor. Our results suggest that both ,-catenin and topo II, independently predicted an adverse prognosis and might serve as new markers for risk stratification in AML patients. Am. J.

[source] Role of definitive radiotherapy in treating patients with inoperable Merkel cell carcinoma: The Westmead Hospital experience and a review of the literatureAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 4 2009Clare SL Koh ABSTRACT Merkel cell carcinoma (MCC) is an uncommon aggressive primary cutaneous neuroendocrine carcinoma with a propensity to spread to regional lymph nodes and distant sites. The head and neck is the commonest site for presentation (50,60%) and recent evidence suggests patients treated with excision (to achieve a negative microscopic margin) and adjuvant wide-field radiotherapy (RTx) have an improved survival compared with surgery alone. Surgery is often not possible in elderly patients with multiple co-morbidities and in patients with advanced lesions. Definitive RTx therefore remains an option in these inoperable patients, with data to report its benefit. We report the results of eight patients with inoperable MCC treated with RTx alone between 1993 and 2007 at Westmead Hospital, Sydney, Australia, and also review the relevant literature on definitive RTx in the treatment of MCC. The median age at diagnosis was 82.5 years in five women and three men. All patients were Caucasian and none were immunosuppressed. Seven of eight patients were clinically node-positive. The mean duration of follow up was 12 months. A median dose of 50 Gy was prescribed. Seven of eight patients with inoperable MCC achieved in-field control, with most eventually relapsing distantly. Treatment-related toxicity was acceptable. In keeping with our results, other studies also report high rates of in-field locoregional control following RTx alone. These findings highlight the radioresponsiveness of advanced MCC and support a recommendation of moderate-dose RTx alone in select cases. Lower-dose palliative dose fractionation schedules (e.g. 25 Gy in five fractions) may be considered in patients of very poor performance status. [source] Acute pulmonary failure during remission induction chemotherapy in adults with acute myeloid leukemia or high-risk myelodysplastic syndromeCANCER, Issue 1 2010Ali Al Ameri MD Abstract BACKGROUND: Acute pulmonary failure during remission induction therapy is a serious complication in patients with acute myeloid leukemia (AML). To the authors' knowledge, the course and prognosis of such patients is not well known. METHODS: A total of 1541 patients referred for remission induction chemotherapy of AML or high-risk myelodysplastic syndrome were retrospectively reviewed. RESULTS: A total of 120 (8%) patients developed acute pulmonary failure within 2 weeks of the initiation of chemotherapy; 87 of these patients (73%) died during remission induction, whereas 17 (14%) achieved a complete response. The median survival among the 120 patients with early acute pulmonary failure was 3 weeks. Predictive factors for the development of early acute pulmonary failure by multivariate analysis were: male sex (P = .00038), acute promyelocytic leukemia (P = .00003), poor performance status (P = .001), lung infiltrates at diagnosis (P = .000001), and increased creatinine (P = .000005). Patients who had 0 to 1, 2, 3, or 4 to 5 adverse factors were found to have estimated predictive incidences of acute pulmonary failure of 3%, 13%, 23%, and 34%, respectively. CONCLUSIONS: Preventive approaches at the start of induction therapy in patients at high risk of pulmonary failure may improve the outcome of these patients.

[source] Clinical implications of nodal marginal zone B-cell lymphoma among Japanese: study of 65 casesCANCER SCIENCE, Issue 1 2007Masaru Kojima To clarify the clinical presentation and outcome of nodal marginal zone B-cell lymphoma (NMZBL), 65 Japanese patients with this disease were studied and compared with the published literature from western countries. The clinical findings of our 65 cases were similar to those of their cases in some aspects: (1) 58% of the patients were >60 years old (median age, 64 years); (2) there was a slight female predominance; (3) 90% of the patients exhibited asymptomatic lymphadenopathy in the head and neck area; (4) only a minority of patients had B symptoms (6%) and poor performance status (8%); and (5) only 5% of patients were positive for M-protein. However, the 65 patients in this series exhibited relatively longer 5-year overall survival (85%) and failure-free survival (60%) than the NMZBL series published in western literature, suggesting that NMZBL should be classified as indolent lymphoma. Moreover, based on the histological findings, we further classified four histological subtypes as follows: (1) splenic type (n = 7); (2) floral type (n = 9); (3) mucosa-associated lymphoid tissue (MALT) type (n = 29); and (4) diffuse large B-cell lymphoma (DLBCL) + MALT type (n = 20). DLBCL + MALT type exhibited significantly poorer 5-year overall survival than the splenic variant. The recognition of DLBCL + MALT type appears important. No API2,MALT1 fusion transcript was detected in any of the 14 cases examined. (Cancer Sci 2007; 98: 44,49) [source] |
