Purpose: Primary bone lymphoma (PBL) represents less than 1% of all malignant lymphomas. In this study, we assessed the disease profile, outcome, and prognostic factors in patients with Stages I and II PBL. Patients and Methods: Thirteen Rare Cancer Network (RCN) institutions enrolled 116 consecutive patients with PBL treated between 1987 and 2008 in this study. Eighty-seven patients underwent chemoradiotherapy (CXRT) without (78) or with (9) surgery, 15 radiotherapy (RT) without (13) or with (2) surgery, and 14 chemotherapy (CXT) without (9) or with (5) surgery. Median RT dose was 40 Gy (range, 4-60). The median number of CXT cycles was six (range, 2-8). Median follow-up was 41 months (range, 6-242). Results: The overall response rate at the end of treatment was 91% (complete response [CR] 74%, partial response [PR] 17%). Local recurrence or progression was observed in 12 (10%) patients and systemic recurrence in 17 (15%). The 5-year overall survival (OS), lymphoma-specific survival (LSS), and local control (LC) were 76%, 78%, and 92%, respectively. In univariate analyses (log-rank test), favorable prognostic factors for OS and LSS were International Prognostic Index (IPI) score ≤1 (p = 0.009), high-grade histology (p = 0.04), CXRT (p = 0.05), CXT (p = 0.0004), CR (p < 0.0001), and RT dose >40 Gy (p = 0.005). For LC, only CR and Stage I were favorable factors. In multivariate analysis, IPI score, RT dose, CR, and CXT were independently influencing the outcome (OS and LSS). CR was the only predicting factor for LC. Conclusion: This large multicenter retrospective study confirms the good prognosis of early-stage PBL treated with combined CXRT. An adequate dose of RT and complete CXT regime were associated with better outcome. © 2012 Elsevier Inc. All rights reserved. Source

Background The incidence of esophageal cancer has grown over the recent decades and 30 % of esophageal cancer patients are now 75 years or older at the time of diagnosis. The aim of this study was to evaluate trends in management and survival of patients aged 75 years or older with esophageal cancer. Methods In the Netherlands cancer registry, we identified all patients aged 75 years or older who were diagnosed with esophageal cancer between 1989 and 2008. Trends in management and survival were analyzed by time period (1989-2001 vs. 2002-2008), TNM stage, and age (75-79, 80-84, and 85? years). X2 testing was used to analyze time trends in treatment, Kaplan-Meier analysis and log-rank testing to estimate survival, and Cox regression model to calculate hazard ratios for death. Results Some 7,253 patients were included in the study. The surgical resection rate increased over the 1989-2008 period from 8.9 to 12.6 % (p = 0.028), especially among patients aged 75-79 years (44.6 vs. 55.4 %, p <0.001) and patients with TNM stage I disease (12.7 vs. 22.0 %, p <0.001). The use of definitive chemoradiotherapy (CRT) also increased (0.19 vs. 2.20 %, p <0.001). Whereas the use of chemotherapy as a single-modality treatment more than doubled (0.64 vs. 1.54 %, p = 0.004), that of radiotherapy alone decreased (38.1 vs. 31.6 %, p <0.001). Although median survival time was marginally higher in the 2002-2008 period than in 1989-2001, overall 5 year survival rates remained low at 6 and 5 %, respectively (p <0.001). Five-year survival rate after surgery increased from 16 to 30 % (p <0.001). Conclusions In patients of 75 years or older, surgical treatment and use of definitive CRT have increased between 1989 and 2008. Also, an increase in the use of chemotherapy as a single modality was noted. Overall 5 year survival for all cancer patients was stable but remained poor, while survival of patients who underwent esophagectomy improved significantly in the Netherlands since 1989. © Société Internationale de Chirurgie 2012.

BACKGROUND: The objective of this study was to evaluate the role of reirradiation and hyperthermia in the treatment of radiation-associated sarcoma (RAS) in the thoracic region, which is an increasing, yet extremely rare condition with a poor prognosis. METHODS: Between 1979 and 2009, 16 patients with RAS in the thoracic region were treated in the Academic Medical Center and the Institute Verbeeten with reirradiation and hyperthermia. In 13 patients, this treatment was given for unresectable disease and 3 times after resection as adjuvant treatment. The median latency period between the original malignancy diagnosis and the RAS diagnosis was 86 months (range 19-212 months). Histology was angiosarcoma in 11 patients (69%). The literature on reirradiation with or without hyperthermia for RAS was reviewed. RESULTS: The median survival was 15.5 months (range, 3-204 months). Four patients were not evaluable for response. The response rate for the remaining 12 patients was 75% (7 complete responses and 2 partial responses). Six patients remained free of local failure until death (5 months and 7 months) or last follow-up (8 months, 11 months, 39 months, and 68 months). CONCLUSIONS: The current study indicates that combined reirradiation and hyperthermia for RAS in the thoracic region is feasible. The high response rate and the possibility of durable local control suggest that this treatment is promising. Copyright © 2011 American Cancer Society. Source

Background: Initial results of the ChemoRadiotherapy for Oesophageal cancer followed by Surgery Study (CROSS) comparing neoadjuvant chemoradiotherapy plus surgery versus surgery alone in patients with squamous cell carcinoma and adenocarcinoma of the oesophagus or oesophagogastric junction showed a significant increase in 5-year overall survival in favour of the neoadjuvant chemoradiotherapy plus surgery group after a median of 45 months' follow-up. In this Article, we report the long-term results after a minimum follow-up of 5 years. Methods: Patients with clinically resectable, locally advanced cancer of the oesophagus or oesophagogastric junction (clinical stage T1N1M0 or T2-3N0-1M0, according to the TNM cancer staging system, sixth edition) were randomly assigned in a 1:1 ratio with permuted blocks of four or six to receive either weekly administration of five cycles of neoadjuvant chemoradiotherapy (intravenous carboplatin [AUC 2 mg/mL per min] and intravenous paclitaxel [50 mg/m2 of body-surface area] for 23 days) with concurrent radiotherapy (41·4 Gy, given in 23 fractions of 1·8 Gy on 5 days per week) followed by surgery, or surgery alone. The primary endpoint was overall survival, analysed by intention-to-treat. No adverse event data were collected beyond those noted in the initial report of the trial. This trial is registered with the Netherlands Trial Register, number NTR487, and has been completed. Findings: Between March 30, 2004, and Dec 2, 2008, 368 patients from eight participating centres (five academic centres and three large non-academic teaching hospitals) in the Netherlands were enrolled into this study and randomly assigned to the two treatment groups: 180 to surgery plus neoadjuvant chemoradiotherapy and 188 to surgery alone. Two patients in the neoadjuvant chemoradiotherapy group withdrew consent, so a total of 366 patients were analysed (178 in the neoadjuvant chemoradiotherapy plus surgery group and 188 in the surgery alone group). Of 171 patients who received any neoadjuvant chemoradiotherapy in this group, 162 (95%) were able to complete the entire neoadjuvant chemoradiotherapy regimen. After a median follow-up for surviving patients of 84·1 months (range 61·1-116·8, IQR 70·7-96·6), median overall survival was 48·6 months (95% CI 32·1-65·1) in the neoadjuvant chemoradiotherapy plus surgery group and 24·0 months (14·2-33·7) in the surgery alone group (HR 0·68 [95% CI 0·53-0·88]; log-rank p=0·003). Median overall survival for patients with squamous cell carcinomas was 81·6 months (95% CI 47·2-116·0) in the neoadjuvant chemoradiotherapy plus surgery group and 21·1 months (15·4-26·7) in the surgery alone group (HR 0·48 [95% CI 0·28-0·83]; log-rank p=0·008); for patients with adenocarcinomas, it was 43·2 months (24·9-61·4) in the neoadjuvant chemoradiotherapy plus surgery group and 27·1 months (13·0-41·2) in the surgery alone group (HR 0·73 [95% CI 0·55-0·98]; log-rank p=0·038). Interpretation: Long-term follow-up confirms the overall survival benefits for neoadjuvant chemoradiotherapy when added to surgery in patients with resectable oesophageal or oesophagogastric junctional cancer. This improvement is clinically relevant for both squamous cell carcinoma and adenocarcinoma subtypes. Therefore, neoadjuvant chemoradiotherapy according to the CROSS trial followed by surgical resection should be regarded as a standard of care for patients with resectable locally advanced oesophageal or oesophagogastric junctional cancer.

Background Modest benefits from concurrent chemoradiotherapy in patients with locally advanced NSCLC warrant further clinical investigations to identify more effective treatment regimens. Cetuximab, a monoclonal antibody against the epidermal growth factor receptor has shown activity in NSCLC. We report on the safety and efficacy of the combination of daily dose Cisplatin and concurrent radiotherapy with or without weekly Cetuximab. Patients and methods Patients received high dose accelerated radiotherapy (66 Gy in 24 fractions) and concurrent daily Cisplatin (6 mg/m2) without (Arm A) or with (Arm B) weekly Cetuximab (400 mg/m2 loading dose one week prior to radiotherapy followed by weekly 250 mg/m2) the primary endpoint of the trial was objective local control rate (OLCR) determined at 6-8 weeks after treatment. Toxicity was reported as well. Results Between February 2009 and May 2011, 102 patients were randomized. Median follow up was 29 months the OLCR was 84% in Arm A and 92% in Arm B (p = 0.36) the one-year local progression free interval (LPFI) and overall survival (OS) were 69% and 82% for Arm A and 73% and 71% for Arm B, respectively (LPFI p = 0.39; OS p = 0.99). Toxicity compared equally between both groups. Conclusion The addition of Cetuximab to radiotherapy and concurrent Cisplatin did not improve disease control in patients with locally advanced NSCLC but increased treatment related toxicity. © 2013 Elsevier Ireland Ltd.
