Final results of the SAKK 16/00 trial: a randomized phase III trial comparing neoadjuvant chemoradiation to chemotherapy alone in stage IIIA/N2 non-small cell lung cancer (NSCLC).

Aim: One standard option in the treatment of stage IIIA/N2 NSCLC is neoadjuvant chemotherapy followed by surgery. We investigated in a randomized trial whether the addition of neoadjuvant radiotherapy would improve the outcome. Here we present the final results of this study. Methods: Patients (pts.) with pathologically proven, resectable stage IIIA/N2 NSCLC, performance status 0-1, and adequate organ function were randomized 1:1 to chemoradiation (CRT) with 3 cycles of neoadjuvant chemotherapy (cisplatin 100 mg/m2 and docetaxel 85 mg/m2 d1, q3weeks) followed by accelerated concomitant boost radiotherapy (RT) with 44 Gy in 22 fractions in 3 weeks, or neoadjuvant chemotherapy alone (CT), with subsequent surgery for all pts. The primary endpoint was event-free survival (EFS). Results: 232 pts. were randomized in 23 centers, the median follow-up was 53 months. Two thirds were men, median age was 60 years (range 37-76). Histology was squamous cell in 33%, adenocarcinoma in 43%. Response rate to CRT was 61% vs. 44% with CT. 85% of all pts. underwent surgery, 30-day postoperative mortality was 1%. The rate of complete resection was 91% (CRT) vs. 81% (CT) and the pathological complete remission (pCR) rate was 16% vs. 12%. The median EFS was 13.1 months (95% CI 9.9 - 23.5) for the CRT group vs. 11.8 months (95% CI 8.4 - 15.2) in the CT arm (p 0.665). The median overall survival (OS) with CRT was 37.1 months (95% CI 22.6 -50), with CT 26.1 months ( 95% CI 26.1 - 52.1, p 0.938). The local failure rate was 23% in both arms. In the CT arm 12 pts. were given postoperative radiotherapy (PORT) for R1 resection, 6 pts. received PORT in violation of the protocol. Pts. with a pCR, mediastinal downstaging to ypN0/1 and complete resection had a better outcome. Toxicity of chemotherapy was substantial, especially febrile neutropenia was common, whereas RT was well tolerated. Conclusions: This is the first completed phase III trial to evaluate the role of induction chemoradiotherapy and surgery, in comparison to neoadjuvant CT alone followed by surgery. RT was active, it increased response, complete resection and pCR rates. However, this failed to translate into an improvement of local control, EFS or OS. Notably, surgery after induction treatment was safe, including pneumonectomy. The overall survival rates of our neoadjuvant regimen are very encouraging, especially for a multicenter setting.

Long recognized as the standard general reference in the field, this completely revised edition of Grainger and Allison's Diagnostic Radiology provides all the information that a trainee needs to master to successfully take their professional certification examinations as well as providing the practicing radiologist with a refresher on topics that may have been forgotten. Organized along an organ and systems basis, this resource covers all diagnostic imaging modalities in an integrated, correlative fashion and focuses on those topics that really matter to a trainee radiologist in the initial years of training

Sleep problems among detainees are common. Appropriate evaluation and treatment remain challenging in correctional settings. However, this is not primarily a problem of resources; rather, it is, to a great extent, an issue of adequate training. Correctional health professionals need appropriate education regarding insomnia evaluation and management. Guidelines should be based on the principle of equivalence of care and should take into account all evidence from research in the community and in correctional settings. Educational material from outside prisons exists and should be made available to detainees and health professionals (Falloon et al., 2011; Sateia & Nowell, 2004). Priority should be given to changes in prison conditions and to nonpharmacological treatment. There is no evidence-based justification to replace BZD prescriptions with antipsychotics or antidepressants. In correctional settings, prescriptions of antipsychotics and antidepressants for sleep problems can increase risk due to polypharmacy and higher suicide risks. Correctional physicians should monitor and document the evaluation and treatment practice concerning insomnia complaints to improve safe, evidence-based treatment.

Ácido ent-16alfa,17-diidroxicauran-19-óico isolado de Ouratea semiserrata e os desafios estereoquímicos dos carbonos quirais C-4 e C-16

Phytochemical investigation of the leaves and branches of a specimen of Ouratea semiserrata led to the isolation and characterization of ent-16alpha,17-dihydroxykauran-19-oic acid, along with other natural products. This diterpenoid and its derivatives were used to unambiguous ¹H and 13C chemical shifts assignments and to indicate some mistake data described in the literature as consequence mainly of the stereochemicals of the chiral carbons C-4 and C-16. The HRMS spectra were also analysed.

Clinically occult metastases in patients with cutaneous melanoma. Detection with sentinel lymph node biopsy and whole body positron emission tomography

Objective: The aim of this study was to investigate the use of sentinel lymph node biopsy (SLNB) and whole body positron emission tomography (PET), with emphasis on surgical treatment and prognosis, in the detection of clinically occult metastases in patients with clinically localized cutaneous melanoma. Patients and methods: The study population consisted of 1255 patients with clinical stage I–II cutaneous melanoma, operated at Turku University Hospital between 1983 and 2007. 334 patients underwent SLNB and they were compared to 921 retrospective patients. A subgroup of 30 symptom-free patients with high risk melanoma underwent prospectively whole body PET 6–24 months postoperatively. Results: Overall, the disease-specific survival rate was 84.4 % at five years. Sex, Breslow thickness, age and nodal status were independent prognostic factors for survival. SLNB revealed occult nodal metastases in 17 % of the patients. There was no significant difference in disease-specific overall survival between SLNB patients and controls, but the nodal disease-free time was significantly longer suggesting better local control after SLNB and subsequent completion lymph node dissection. The followup time was different between the study cohorts and initial surgery was performed during different time periods. SLNB detected micrometastases in seven of 155 patients (4.5 %) with thin T1 primary melanoma and in four of 25 patients (16 %) with head and neck melanoma. In six of 30 asymptomatic patients with high risk melanoma (20 %), whole body PET detected occult distant metastases. Conclusion: Both SLNB and whole body PET were reliable methods to detect clinically occult metastases in patients with cutaneous melanoma. This upstaging altered the treatment in each case.

Sobre la Ley de Patrimonio Histórico. Ley 16/1985

Las leyes que han ido preservando el patrimonio a lo largo del tiempo han evolucionado según el significado que ha ido teniendo a lo largo de la historia, pasando de un concepto de propiedad y disfrute individual en sus inicios, a otro mucho más colectivo en los últimos tiempos. Esta evolución no sólo se ha limitado a la propiedad sino que también lo ha hecho como elemento identificador de una sociedad, proporcionando una secuencia histórica de las leyes relativas a la conservación y divulgación del patrimonio histórico.
