Cross-cultural adaptation, reliability and validity of the Spanish version of the long-term quality of life questionnaire.

Purpose: The aim of this study was to translate, culturally adapt, and evaluate the psychometric properties of the Spanish Long-Term Quality of Life (LTQL) questionnaire. Methods: The LTQL was initially translated into Spanish and cross-culturally adapted based on established guidelines. The Spanish LTQL was administered to patients with breast cancer who had completed their initial treatment 5 years earlier, along with other self-report measures: Quality of Life in Adult Cancer Survivors (QLACS), Hospital Anxiety and Depression Scale (HADS) and EORT-QLQ-BR23. Reliability was evaluated using internal consistency and test-retest. Convergent and known-groups validity were examined. Structural validity as determined by confirmatory factor analysis (CFA) and Rasch analyses was used to assess the unidimensionality and item-functioning of the LTQL domains. Results: Cronbach's alpha were above 0.7 in all domains. Test-retest coefficients were between 0.72 to 0.96 for LTQL domains. LTQL total score was correlated with others total scores of other measures: QLACS (r=-0.39), HADS depression (r=-0.57), HADS anxiety (-0.45) and EORTC-QLQ-BR23 (r=-0.50). CFA provided satisfactory fit indices, with RMSEA value of 0.077 and TLI and CFI values of 0.901 and 0.909, respectively. All factor loadings were higher than 0.40 and statistically significant (P<0.001). Rasch analysis showed that Somatic Concerns domain had 4 misfitting items, and Philosophical/Spiritual View of Life and social Support domains only 1 misfit item. However, unidimensionality was supported for the four domains. Conclusion: The findings support the validity and reliability of the Spanish version of LTQL questionnaire to be used in long-term cancer female survivors.

Factores predictivos de supervivencia a largo plazo del cáncer colorrectal tras la ablación de metástasis hepáticas con control ultrasonográfico / Predictive factors of long-term colorectal cancer survival after ultrasound-controlled ablation of hepatic metastases

Antecedentes y objetivo: Se evaluaron los factores de riesgo asociados a supervivencia a largo plazo en pacientes con metástasis hepáticas de carcinoma colorrectal sometidos a tratamientos ablativos. Pacientes y métodos: Estudio de cohorte unicéntrico, retrospectivo, analizando los pacientes consecutiva y prospectivamente, presentando metástasis hepáticas no resecables de carcinoma colorrectal, siendo tratados con procedimientos ablativos entre 1996 y 2013. Los factores asociados a supervivencia fueron identificados utilizando el modelo de Cox de riesgo proporcional con covariables dependientes del tiempo. También se realizó una selección de variables con el criterio de información de Akaike. Se calcularon el riesgo relativo y los intervalos de confianza al 95% para cada factor. La significación estadística se estableció en p<0,05. Resultados: Setenta y cinco pacientes con metástasis hepáticas de cáncer colorrectal, con una edad media de 65,6 (10,3) años, fueron sometidos a 106 tratamientos. Las variables seleccionadas fueron: extensión tumoral (RR 3,070, IC 95% 1,776-5,308) y buena calidad de vida (RR 0,308, IC 95% 0,150-0,632). La mediana de supervivencia global fue de 18,5 meses (IC 95% 17,4-24,4) y la mediana de pronóstico de supervivencia, de 13,5 frente a 23,4 meses para pacientes con y sin extensión del tumor, y de 23 frente a 12,8 meses para pacientes con buena y regular o mala calidad de vida, respectivamente. Conclusiones: La extensión tumoral y la buena calidad de vida fueron los únicos factores predictivos estadísticamente significativos de supervivencia a largo plazo en pacientes con carcinoma colorrectal con metástasis hepáticas sometidos a tratamiento ablativo con control ultrasonográfico (AU)

Background and objective: The risk factors associated to long-term survival were assessed in patients with liver metastases of colorectal carcinoma undergoing ablative therapies. Patients and methods: Single-centre cohort study, retrospectively analysed and prospectively collected consecutive patients with unresectable metastatic liver disease of colorectal carcinoma treated with ablative therapies between 1996 and 2013. Factors associated with survival time were identified using Cox's proportional hazard model with time-dependent covariates. A forward variable selection based on Akaike information criterion was performed. Relative risk and 95% confidence intervals for each factor were calculated. Statistical significance was set as P<.05. Results: Seventy-five patients with liver metastases of colorectal cancer, with a mean age of 65.6 (10.3) underwent 106 treatments. Variables selected were good quality of life (RR 0.308, 95% CI 0.150-0.632) and tumour extension (RR 3.070, 95% CI 1.776-5.308). The median overall survival was 18.5 months (95% CI 17.4-24.4). The survival prognosis in median was 13.5 vs. 23.4 months for patients with and without tumour extension, and 23.0 vs. 12.8 months for patients with good and fair or poor quality of life, respectively. Conclusions: Good quality of life and tumour extension were the only statistically significant predictors of long-term survival in patients of colorectal carcinoma with liver metastatic disease undergoing ablative treatment with ultrasound (AU)

Lumbar region intra-spinal primitive neuroectodermal tumour (PNET) combined with neurofibromatosis type 1

Primitive neuroectodermal tumours (PNET) are aggressive neoplasias that are diagnosed, usually, in infancy. Their appearance in adulthood is rare and, exceptionally, in association with neurofibromatosis type I (NF-1). We present a case of a 37 year-old man with NF-1 combined with PNET in the intra-arachidial lumbar region. Diagnosis was by Nuclear Magnetic Resonance (NMR) and biopsy of soft tissue mass which showed a PNET with undifferentiated round cells and immunohistochemically positive for CD99, neurone-specific enolase, synaptophysin and LEU-7. Surgery was performed with spine decompression and resection of 80% of the tumour, with symptoms improvement. Radiotherapy was administered on the lumbosacral column, but only up to 30 Gy because of severe actinic enteritis and pan-cytopenia grade III. Six months later, the patient was hospitalized with deterioration in his overall clinical status with multi-organ involvement. The patient died and an autopsy was performed. The initial treatment of the PNET is surgery and, if possible, the radical extirpation of the tumour. Administration of radiotherapy and chemotherapy appears to increase survival. We comment on the clinical, histological, cytological and immunohistochemical aspects together with a review of the literature. To the best of our knowledge this is the first documentation of such a case
