We present here the analysis of the subgroup of patients undergoing combined surgery from the Spanish Group of Surgery of Pulmonary Metastases (PM) from Colorectal Carcinoma (GECMP-CCR-SEPAR). We analyze characteristics, survival and prognostic factors of patients undergoing combined resection from March-2008 to February-2010 and followed-up during at least 3 years, from the prospective multicenter Spanish Registry. A total of 138 patients from a whole series of 543 cases from 32 thoracic surgery units underwent both procedures. Seventy-seven (43.8%) resected liver metastases were synchronic with colorectal tumor. Median disease specific survival (DSS) from first pulmonary metastasectomy was 48.9 months, being three and 5-year DSS 65.1% and 41.7%, respectively. From CRC-surgery median DSS was 97.2 months, with 3 and 5-year DSS rates of ...

The activities, treatment patterns and results achieved by assisted reproduction centres in Spain were examined, comparing public and private clinics. A retrospective study was carried out using the Assisted Reproductive Technology Register of the Spanish Fertility Society for 2002-2004. The results showed that 74%, 96% and 99% of IVF/intracytoplasmic sperm injection, oocyte donation and preimplantation genetic diagnosis cycles, respectively, were carried out in the private sector. Public clinics performed proportionally more transfers of three embryos than the private clinics (48.1% versus 41.7%). More elective transfers were performed in private clinics. Pregnancy rates per cycle started, per puncture and per transfer were significantly higher among private than public clinics (29.1%, 32.7% and 35.9% versus 25.2%, 28.5% and 32.6%, respectively) (P < 0.05). Implantation rate has risen year on year in both types of clinic and was significantly higher (P < 0.05), every year, among the private clinics. The multiple-pregnancy rate was significantly higher among the private clinics (30.8% versus 26.4%) (P < 0.05). In conclusion, differences exist between public and private clinics as regards to their volume of activity, the range of services offered, clinical practice and results achieved.

There exist various methods for comparing and analysing the results of clinical activity, with graphical methods being the most commonly used for this purpose. As yet, there is no general consensus as to how the poor performance (PP) or optimum performance (OP) of assisted reproductive technologies should be defined. METHODS: Data from the IVF/ICSI register of the Spanish Fertility Society were used to compare and analyse different definitions of PP or OP. The primary variable best reflecting the quality of an IVF/ICSI programme was taken to be the percentage of singleton births per IVF/ICSI cycle initiated. Of the 75 infertility clinics that took part in the SEF-2003 survey, data on births were provided by 58. A total of 25 462 cycles were analysed. The following graphical classification methods were used: ranking of the proportion of singleton births per cycles started in each centre (league table), Shewhart control charts, funnel plots, best and worst-case scenarios and state of the art methods. RESULTS: The clinics classified as producing PP or OP varied considerably depending on the classification method used. Only three were rated as providing 'PP' or 'OP' by all methods, unanimously. Another four clinics were classified as 'poor' or 'optimum' by all the methods except one. CONCLUSIONS: On interpreting the results derived from IVF/ICSI centres, it is essential to take into account the characteristics of the method used for this purpose.

A prospective observational study conducted in 164 patients aged ≥65years and diagnosed with myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML), multiple myeloma (MM), or chronic lymphocytic leukemia (CLL). Responsiveness of the GAH scales was studied by means of the Eastern Cooperative Oncology Group (ECOG) score, the Karnofsky performance status (KPS) score, the visual analog scale (VAS), and the physician's subjective assessment, used as clinical anchors to identify whether patients had changed clinically (either improved or worsened) or not since the baseline visit. Responsiveness was evaluated on the basis of effect size (ES). 164 patients (men, 63.7%; median age, 77.0 (72.8-81.4) participated. Statistically significant correlations were obtained between the inv...
