Background: Malignant pleural effusion is a clinical problem that impairs Quality of Life in patients with advanced malignancies. An indwelling pleural catheter is an alternative treatment to palliate some of the symptoms. Aim: To evaluate the Quality of Life of outpatients with malignant pleural effusion who were treated with an indwelling pleural catheter. Questionnaire compliance, catheter patency time, and survival were analyzed. Design: A multicenter observational study was conducted across five hospitals in Spain. Quality of Life was assessed at three different time points (before catheter placement and at 30 and 60 days post-placement) using the European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire QLQ-C30. For lung cancer patients, the QLQ-LC13 was also used. Participants: Patients with recurrent malignant pleural effusion treated with an indwelling pleural catheter. Results: A total of 51 outpatients completed the baseline QLQ-C30 questionnaire. Of these, 28 completed the questionnaire at 30 days. Of these 28 patients, 13 completed the questionnaire at 60 days. Scores showed a significant improvement in symptoms scales at 30 days (p = 0.03). Global health status and functional scales showed a non-significant trend to improvement at 30 and 60 days. A total of 27 lung cancer patients completed the QLQ-LC13 questionnaire. Items assessing dyspnea showed a significant improvement following catheter placement (p = 0.002). Conclusion: Indwelling pleural catheter is useful for palliative management of recurrent malignant pleural effusion in that it benefits Quality of Life in outpatients with advanced malignancies. In lung cancer patients, scores indicated that indwelling pleural catheter also provides significant relief of dyspnea.©The Author(s) 2014. Source

Solitary plasmacytoma represents a heterogeneous group of patients; approximately half develop multiple myeloma (MM) in 2 or 3 years,whereas others remain disease-free at 10 years. By definition, these patients do not have morphologic bone marrow (BM) plasma cell (PC) infiltration. Here, we investigated whether sensitive BM evaluation of patients withsolitaryboneplasmacytoma(SBP; n = 35) andextramedullary plasmacytoma (EMP; n = 29) through multiparameter flow cytometry (MFC) would unravel the presence of clonal PCs in otherwise disease-free BM, and whether BMclonality predicted higher risk of progression. BMclonal PCs were detected in 17 of 35 SBP (49%) and 11 of 29 EMP (38%) patients. Seventy-one percent of flow-positive vs only 8% of flow-negative SBP patients evolved to MM (median time to progression of 26 months vs not reached; hazard ratio, 17.4; P < .001). No significant differences were observed among EMP cases. Our results highlight the importance of MFC for sensitive BM evaluation of SBP patients, to predict risk of developing treatment-requiring MM and to plan disease monitoring. © 2014 by The American Society of Hematology.

Results: At a median follow-up of 79.0 months (range 3–250 months), a total of 80 patients (24.7 %) relapsed. The observed 5- and 10-year overall survival (OS) was 83.2 and 74.9 %, respectively. The 5- and 10-year disease-free survival (DFS) was 75.1 and 71.4 %, respectively. A significant correlation was found between the TRG and survival (log rank, p < 0.001). The 10-year OS was 32.7 % for grade 1, 63.8 % for grade 2, 75.0 % for grade 3, 90.4 % for grade 3+, and 96.0 %,for grade 4. The 10-year DFS was 31.8 % for grade 1, 58.6 % for grade 2, 70.4 % for grade 3, 88.4 % for grade 3+, and 97.1 % for grade 4. In patients with PLVI, the TRG had no impact on survival. When excluding patients with PLVI, the TRG was an independent prognostic factor for OS and DFS.Background: The prognostic significance of perineural and/or lymphovascular invasion (PLVI) and its relationship with tumor regression grade (TRG) in patients with locally advanced rectal cancer (LARC) treated with neoadjuvant chemoradiotherapy (CRT) and surgery.Methods: A total of 324 patients with LARC were treated with CRT and operated on between January 1992 and June 2007. Tumors were graded using a quantitative 5-grade TRG classification and the presence of PLVI was histologically studied.Conclusions: The presence of PLVI is a more powerful prognostic factor than TRG in LARC patients treated with neoadjuvant CRT followed by surgery. PLVI denotes an aggressive phenotype, suggesting that these patients may benefit from adjuvant systemic therapy. © 2014, Society of Surgical Oncology. Source

Background: To assess whether deletions involving codons 557 and/or 558 (critical deletions) of exon 11 of KIT are relevant in the prognosis of relapse-free survival (RFS) in gastrointestinal stromal tumor (GIST) patients with a long follow-up. Patients and methods: A univariate and multivariate analysis for RFS were carried out on 162 localized GIST patients over the entire follow-up period and over the intervals 0-4 years and >4 years. Factors assessed among others were Fletcher/National Institutes of Health and Miettinen-Lasota/Armed Forces Institute of Pathology (M-L/AFIP) risk categories, critical deletions and non-deletion-type mutation (NDTM) within exon 11 of KIT. Results: Multivariate analyses revealed that M-L/AFIP [relative risk (RR) 11.45, confidence interval (CI) 4.40-29.76, for the high-risk subgroup and RR 5.97, CI 2.09-17.06, for the intermediate subgroup] and critical deletions (RR 3.05, CI 1.59-5.85) were independent prognostic factors for RFS for the first 4 years and for the entire follow-up period. Beyond 4 years, the high-risk M-L/AFIP subgroup (RR 8.12, CI 1.48-44.4) and NDTM (RR 6.42, CI 1.17-35.12) were independent prognostic factors for RFS. The median follow-up was 84 months. Conclusion: Critical deletions represent a time-dependent prognostic factor limited to the first 4 years after surgery, which could help identify a subset with higher and earlier risk for relapse in GIST patients. © The Author 2010.

The clinical value of multiparameter flow cytometry (MFC) immunophenotyping in primary or light chain amyloidosis (AL) remains unknown. We studied 44 consecutive bone marrow samples from newly diagnosed patients with amyloidosis; 35 patients with AL and 9 with other forms of amyloidosis. Monoclonal plasma cells (PCs) were identifiable by MFC immunophenotyping in 34 of 35 (97%) patients with AL, whereas it was absent from all but 1 of the 9 (11%) patients with other forms of amyloidosis. Quantification of bone marrow plasma cells (BMPCs) by MFC immunophenotyping was a significant prognostic factor for overall survival (OS) (≤ 1% vs > 1% BMPC cutoff; 2-year OS rates of 90% vs 44%, P = .02). Moreover, detecting persistent normal PCs at diagnosis identifies a subgroup of patients withAL with prolonged OS (> 5% vs ≤ 5% normal PC within all BMPC cutoff, 2-year rates of 88% vs 37%, P = .01). MFC immunophenotyping could be clinically useful for the demonstration of PC clonality in AL and for the prognostication of patients with AL. © 2011 by The American Society of Hematology. Source
