Quality of life in patients with breakthrough cancer pain in radiation oncology departments in Spain: the CAVIDIOR study.

Aim: The CAVIDIOR study evaluated quality of life (QoL) in patients with breakthrough cancer pain receiving palliative radiation therapy in radiation oncology departments (RODs) in Spain. Patients & methods: Prospective observational study at 11 Spanish RODs (July 2016-November 2017). QoL was assessed using Short Form Health Survey 12. Secondary end points were sleep quality, caregiver burden and patient/perception of improvement. Results: QoL improved according to the Short Form Health Survey 12 mental component. Sleep quality and caregivers' burden improved significantly. Conclusion: Breakthrough cancer pain is highly prevalent and can be substantially reduced with appropriate diagnosis and management in RODs. Along with the QoL questionnaire, sleep quality and caregiver burden provide a more comprehensive assessment of overall health status in patients receiving radiation therapy in RODs. Clinical trial registration: NCT02836379 (ClinicalTrials.gov).

Global radiation oncology waybill.

BACKGROUND/AIM: Radiation oncology covers many different fields of knowledge and skills. Indeed, this medical specialty links physics, biology, research, and formation as well as surgical and clinical procedures and even rehabilitation and aesthetics. The current socio-economic situation and professional competences affect the development and future or this specialty. The aim of this article was to analyze and highlight the underlying pillars and foundations of radiation oncology, indicating the steps implicated in the future developments or competences of each. METHODS: This study has collected data from the literature and includes highlights from discussions carried out during the XVII Congress of the Spanish Society of Radiation Oncology (SEOR) held in Vigo in June, 2013. Most of the aspects and domains of radiation oncology were analyzed, achieving recommendations for the many skills and knowledge related to physics, biology, research, and formation as well as surgical and clinical procedures and even supportive care and management. RESULTS: Considering the data from the literature and the discussions of the XVII SEOR Meeting, the "waybill" for the forthcoming years has been described in this article including all the aspects related to the needs of radiation oncology. CONCLUSIONS: Professional competences affect the development and future of this specialty. All the types of radio-modulation are competences of radiation oncologists. On the other hand, the pillars of Radiation Oncology are based on experience and research in every area of Radiation Oncology.

Two different scenarios of advanced basal cell carcinomas during the use of vismodegib: Cases of oral administration and administration directly to the stomach.

No effective therapy exists for locally advanced or metastatic basal cell carcinoma (BCC). Vismodegib is a small molecule that is an inhibitor of the hedgehog pathway. An oral treatment to inactivate Smoothened would be a new therapeutic approach to treat advanced BCC. We studied two patients with advanced BCC and analysed variables, including age and sex of the patient, tumour location and size, time of evolution and nature of the tumour (primary or recurrent), type of treatment, route of administration, treatment duration, and treatment response. The most important side effects were determined. The patients received oral vismodegib (150 mg) daily. The male patient experienced difficulty in swallowing, which necessitated administration of the drug using a percutaneous endoscopic gastrostomy tube. In the first few months of treatment, both patients displayed significant improvement with almost complete disappearance of the skin lesions in one case and more than 50% in the other case. The median duration of response was 7.6 months. The side effects observed were of slight relevance; alopecia, dysgeusia, asthenia, and fatigue were easily resolved with the appropriate treatments. Vismodegib appears to be well tolerated and effective in treating advanced and metastatic BCC. No serious adverse events were reported.

Myxoid liposarcoma associated with adalimumab treatment: A case report.

Biological agents that suppress inflammation, such as tumour necrosis factor (TNF-α) inhibitors, are being successfully used at an increasing frequency for the treatment of chronic inflammatory diseases, such as psoriasis. However, these drugs are not free of side effects, and although the general rates of malignancy in patients using anti-TNF-α therapies are not high, certain tumours of cutaneous origin, particularly carcinomas, have been reported. We herein present the case of a 47-year-old female patient with moderate-to-severe psoriasis for 20 years under treatment with adalimumab administered at the standard dose of 40 mg, injected subcutaneously each fortnight, with good efficacy. To the best of our knowledge, this is the first reported case of a low-grade (grade 1) myxoid liposarcoma in a patient receiving treatment with adalimumab since 2009. A review of the relevant literature was also conducted. Continuous investigation of such cases is crucial in order to elucidate the iatrogenic risk of rare cancers, such as myxoid liposarcoma, in patients undergoing treatment with currently available as well as future biological therapies.

Linear Accelerator Stereotactic Radiosurgery of Central Nervous System Arteriovenous Malformations: A 15-Year Analysis of Outcome-Related Factors in a Single Tertiary Center.

BACKGROUND: Linear accelerator stereotactic radiosurgery is one of the modalities available for the treatment of central nervous system arteriovenous malformations (AVMs). The aim of this study was to describe our 15-year experience with this technique in a single tertiary center and the analysis of outcome-related factors. METHODS: From 1998 to 2013, 195 patients were treated with linear accelerator-based radiosurgery; we conducted a retrospective study collecting patient- and AVM-related variables. Treatment outcomes were obliteration, posttreatment hemorrhage, symptomatic radiation-induced changes, and 3-year neurologic status. We also analyzed prognostic factors of each outcome and predictability analysis of 5 scales: Spetzler-Martin grade, Lawton-Young supplementary and Lawton combined scores, radiosurgery-based AVM score, Virginia Radiosurgery AVM Scale, and Heidelberg score. RESULTS: Overall obliteration rate was 81%. Nidus diameter and venous drainage were predictive of obliteration (P < 0.05), ruptured status and previous embolization were not related to rate of obliteration, and low-grade AVMs had higher obliteration rates. Posttreatment hemorrhage incidence was 8.72%; nidus diameter was the only predictor (P = 0.05). Symptomatic radiation-induced changes occurred in 11.79% of patients and were significantly associated with unruptured status (P < 0.05). Treatment success as a composite measure was obtained in 70.77% of patients. Receiver operating characteristic curves were presented for each scoring system and outcome measure; best area under the curve was 0.687 for Lawton combined score in the obliteration outcome. CONCLUSIONS: In the long-term, linear accelerator-based radiosurgery is a useful, valid, effective, and safe modality for treatment of brain AVMs.

Linear accelerator stereotactic radiosurgery for trigeminal neuralgia.

BACKGROUND: Stereotactic radiosurgery is accepted as an alternative for patients with refractory trigeminal neuralgia, but existing evidence is fundamentally based on the Gamma Knife, which is a specific device for intracranial neurosurgery, available in few facilities. Over the last decade it has been shown that the use of linear accelerators can achieve similar diagnostic accuracy and equivalent dose distribution. OBJECTIVES: To assess the effectiveness and safety of linear-accelerator stereotactic radiosurgery for the treatment of patients with refractory trigeminal neuralgia. METHODS: We carried out a systematic search of the literature in the main electronic databases (PubMed, Embase, ISI Web of Knowledge, Cochrane, Biomed Central, IBECS, IME, CRD) and reviewed grey literature. All original studies on the subject published in Spanish, French, English, and Portuguese were eligible for inclusion. The selection and critical assessment was carried out by 2 independent reviewers based on pre-defined criteria. In view of the impossibility of carrying out a pooled analysis, data were analyzed in a qualitative way. RESULTS: Eleven case series were included. In these, satisfactory pain relief (BIN I-IIIb or reduction in pain = 50) was achieved in 75% to 95.7% of the patients treated. The mean time to relief from pain ranged from 8.5 days to 3.8 months. The percentage of patients who presented with recurrences after one year of follow-up ranged from 5% to 28.8%. Facial swelling or hypoesthesia, mostly of a mild-moderate grade appeared in 7.5% - 51.9% of the patients. Complete anaesthesia dolorosa was registered in only study (5.3%). Cases of hearing loss (2.5%), brainstem edema (5.8%), and neurotrophic keratoplasty (3.5%) were also isolated. CONCLUSIONS: The results suggest that stereotactic radiosurgery with linear accelerators could constitute an effective and safe therapeutic alternative for drug-resistant trigeminal neuralgia. However, existing studies leave important doubts as to optimal treatment doses or the therapeutic target, long-term recurrence, and do not help identify which subgroups of patients could most benefit from this technique. LIMITATIONS: Paucity of literature and clear lack of clarification for clinical utilization of this technique.

Evaluación de la calidad de un servicio de voluntariado en oncología: un Análisis Importancia-Valoración (IPA) / Quality assessment of a volunteer service in oncology: an importance performance analysis (IPA)

Objetivo: Usando el Análisis de Importancia-Valoración (IPA), este artículo examina la importancia y valoración percibidas por pacientes oncológicos y sus acompañantes de un programa de humanización realizado por voluntarios en un servicio de Radioterapia de un hospital general en España. Método: Los autores identifican una lista de siete ítems que surgen de la revisión de literatura en Marketing Sanitario; cada ítem fue puntuado con una escala Likert de 5 puntos. Resultados: Los resultados se obtuvieron de las respuestas a 148 entrevistas. El gráfico fue corregido con las recomendaciones sugeridas en la literatura y en el caso de los pacientes, muestra tres factores que caen en el cuadrante de "Mantener el buen trabajo", cuatro atributos caen dentro del cuadrante de "Baja Prioridad" y ningún atributo se observa en los cuadrantes de "Posible dilapidación de recursos" y "Concentrarse aquí". Se encuentran diferencias entre medias de la muestra de pacientes (n=68) y de familiares acompañantes (n=80) en los atributos de catering (t=-2,38; g.l.=146; p<0,05), y en el de información (t=2,16; g.l.=146; p<0,05). Conclusiones: Los resultados parecen útiles para identificar áreas de interés para los gestores de los servicios de salud para desarrollar programas de humanización de servicios basados en el trabajo de voluntarios y dirigidos a diferentes tipos de usuarios. Las implicaciones para los gerentes de programas de voluntariado e investigadores son discutidas

Objective: Using an Importance-Performance Analysis (IPA), this paper examined a Radiotherapy and Oncological Patient and Non-patient perceived importance and performance of ten Humanization Volunteer Program selection factors in the General Hospital in Spain. Methods: The authors identified a list of seven items from the Health-marketing literature reviews, and each item was rated using a 5-point Likert scale. Responses were obtained of 148 usable interviews. Results: The importance-performance patient grid was corrected with literature recommendations and, in the patient sample, shows three items fall in the "Keep up the good work" quadrant, four items fall into the "Low priority" quadrant, zero items fall into the "Possible overkill" quadrant, and no items fall in the "Concentrate here" quadrant. Nonpatient (n=80) factors means shows statistical differences with patient (n=68) means in catering (t=-2.38; df.=146; p<0.05), and information (t=2.16; df146; p<0.05). Conclusions: The results are useful in identifying areas for strategic focus to help Health Services managers develop humanization programs with volunteer workers and different program users. Implication to volunteer programs managers and researchers were discussed

[Local recurrence after radical prostatectomy and salvage radiotherapy]. / Recidiva local después de la prostatectomía radical y radioterapia de rescate.

OBJECTIVE: To evaluate the efficacy of radiotherapy to the prostatic bed in patients with biochemical recurrence prostate cancer after radical prostatectomy. METHODS: We analyse the outcomes of 292 patients who underwent radical prostatectomy for localized prostate cancer T1-T2 between January 1992 and June 2003, with an average follow-up of 36 months (range 6 months to 12 years). We detected biochemical recurrence (PSA > 0.20 ng/ml) in 75 (26%) patients. 75 patients with biochemical recurrence, 9 (12%) were diagnosed of local recurrence by the following criteria: a) First PSA obtained 6 weeks after radical prostatectomy < 0.20 ng/ml. b) Time to biochemical recurrence > 6 months. c) Prostate specific antigen doubling time > 6 months. d) Prostate specific antigen velocity after radical prostatectomy < 0.75 ng/ml/year. e) Prostate specific antigen level after radical prostatectomy < 2.5 ng/ml. The 9 patients diagnosed of local recurrence received an average dose of 56.42 Gy to the prostate bed. RESULTS: Of all 9 patients with local recurrence, 8(88.8%) have complete response with a mean follow-up of 30 months (12-36 months). The time between the radiotherapy and the response, in patients with complete response, was lower than 3 months in 7 patients and 12 months in 1 patient. Significant adverse effects associated to radiotherapy were not observed. CONCLUSIONS: Salvage radiotherapy may be beneficial in selected patients with local recurrence. The characteristics of prostate specific antigen elevation are useful in distinguishing men with local recurrence from those with distant metastases.
