Stereotactic body radiation therapy for liver metastasis from colorectal cancer: size matters.

PURPOSE: We analysed our initial experience with SBRT in liver metastasis from colorectal cancer at our institution. MATERIALS AND METHODS: Between January/2014 and December/2017, 22 patients with 31 LMCCR were treated. Local control (LC) was assessed using the Kaplan-Meier and log-rank tests. We analysed potential prognostic factors for LC: sex, PTV size, number of LM and the radiation scheme. RESULTS: Median age: 69 years. Prior chemotherapy or local liver treatments: 81.8% and 63.6% of patients, respectively. SBRT consisted of 3 × 20 Gy (42.9%) and 3 × 15 Gy (31.4%). There were 88.5% responses (57.1% CR and 31.4% PR). Median follow-up was 30 months. LC per lesion at 12 and 24 months was 85.3% and 61.8%, respectively. Tumour volumes > 30 cc correlated with worsened 2-year-control rates (90% vs 34.5%) (p = 0.005). There was only a patient with CTC-grade 3 toxicity. CONCLUSIONS: Liver SBRT is a safe and effective treatment that achieves high local control rates. We found a significant correlation between larger LMCRC and worse local control.

Reirradiación con radioterapia estereotáxica corporal (SBRT) en recidiva irresecable de cáncer de cabeza y cuello: a propósito de un caso / Re-irradiation with SBRT (Stereotactic Body Radiation Therapy) for locoregional unresectable relapse of head and neck cancer: a case report

Los pacientes con recidiva irresecable de un cáncer de cabeza y cuello (CCC) tienen un pronóstico desfavorable, con limitadas opciones de tratamiento. Los recientes avances técnicos permiten administrar la radioterapia (RT) con gran precisión, haciendo posible reirradiar tumores recidivados mediante radioterapia estereotáxica corporal (SBRT), administrando dosis elevadas de RT al mismo tiempo que se protegen los tejidos sanos próximos al tumor. Aunque esta técnica se ha utilizado para irradiar distintos tumores primarios y sus metástasis, la SBRT en cabeza y cuello ha tenido una evolución mucho más lenta que en otras localizaciones debido a las dificultades para reirradiar los CCC, por la toxicidad esperable al tratarse de una zona relativamente pequeña con gran vascularización e inervación, y donde se asientan varios sentidos. Presentamos el primer caso clínico de reirradiación con SBRT de una recidiva de un CCC en el Complejo Hospitalario de Navarra, que mostró respuesta completa y que permanece asintomático dieciséis meses después

Patients with an unresectable recurrence of head and neck carcinoma (HNC) have a poor prognosis, with limited treatment options. Recent technical advances allow radiotherapy (RT) to be handled with great precision, making it possible to re-irradiate recurrent tumors by means of stereotactic body radiotherapy (SBRT) with high doses of RT while protecting healthy tissues near the tumor. Although this technique has been used to irradiate different primary tumors and their metastases, SBRT in HNC has had a much slower evolution than in the mentioned locations. This is due to the difficulties in re-irradiating the HNC, because of the expected toxicity as it is a relatively small area with dense vascularization and innervation, and where several senses are located. We present the first case of a HNC re-irradiated with SBRT in the Complejo Hospitalario de Navarra; the patient showed a complete response and continues to be disease-free sixteen months after the irradiation

Quality of life in elderly breast cancer patients with localized disease receiving endocrine treatment: a prospective study.

PURPOSE: In this paper we study the quality of life (QoL) of elderly breast cancer patients receiving endocrine treatment (ET). More QoL data on elderly patients treated with ET are needed. Our aims are to study QoL in early-stage breast cancer patients throughout the treatment period and compare the QoL of ET groups. METHODS: 148 patients > 65 years who began ET with either tamoxifen or aromatase inhibitor (AI) completed the EORTC QLQ-C30 and QLQ-BR23 and the Interview for Deterioration in Daily Living Activities in Dementia (IDDD) questionnaires three times over 3 years of ET. Linear mixed-effect models were used to evaluate longitudinal QoL changes. ET group comparisons were conducted after 3 years of treatment via ANCOVA adjusted by basal QoL. RESULTS: QoL scores were high (> 80/100 points) in most QoL areas, with moderate limitations (> 30) in sexual functioning and enjoyment and in future perspective. After 3 years of ET, four QoL areas improved (< 6 points) compared to baseline and 3-month assessments. Hot flushes worsened (8 points) at the 3-month assessment but by 3 years had recovered. AI patients showed more hot flushes, pain and diarrhea and less sexual enjoyment than tamoxifen patients after 3 years of ET (differences 3-12 points). CONCLUSIONS: Results indicate that elderly early-stage breast cancer patients adapted well to their disease and ET treatment over the 3 years. Few QoL differences were observed between ET groups.

Fecal incontinence and radiation dose on anal sphincter in patients with locally advanced rectal cancer (LARC) treated with preoperative chemoradiotherapy: a retrospective, single-institutional study

Background. The objective of the study is to determine the correlations among the variables of dose and the sphincter function (SF) in patients with locally advanced rectal cancer treated with preoperative capecitabine/radiotherapy followed by low anterior resection (LAR) + TME. Methods. We retrospectively reviewed 92 consecutive patients with LARC treated at our center with LAR from 2006 and more than 2 years free from disease. We re-contoured the anal sphincters (AS) of patients with the help of the radiologist. SF was assessed with the Wexner scale (0-20 points, being punctuation inversely proportional to annal sphincter functionality). All questionnaires were filled out between January 2010 and December 2012. Dosimetric parameters that have been studied include V20, V30, V40, V50, mean dose (Dmean), minimum dose (Dmin), D90 (dose received by 90% of the sphincter) and D98. Statistical analysis. The correlations among the variables of dose and SF were studied by the Spearman correlation coefficient. Differences in SF relating to maximum doses to the sphincter were assessed by the Mann-Whitney test. Results. Mean Wexner score was 5.5 points higher in those patients with V20 > 0 compared to those for which V20 = 0 (p = 0.008). In a multivariate regression model, results suggest that the effect of V20 on poor anal sphincter control is independent of the effect of distance, with an adjusted OR of 3.42. Conclusions. In order to improve the SF in rectal cancer treated with preoperative radiotherapy/capecitabine followed by conservative surgery, the maximum radiation dose to the AS should be limited, when possible, to <20 Gy (AU)

Dolor irruptivo oncológico inducido por radioterapia: ¿es posible optimizar su tratamiento? / Radiotherapy-induced breakthrough cancer pain: is it possible to optimize its treatment?

Introducción: en el contexto de la radioterapia, el control del dolor irruptivo oncológico (DIO) supone un reto especial. El DIO ha sido definido por la Sociedad Española del Dolor (SED), la Sociedad Española de Oncología Médica (SEOM) y la Sociedad Española de Cuidados Paliativos (SECPAL) como una exacerbación del dolor súbita y transitoria, de gran intensidad (EVA > 7) y de corta duración (inferior a 20-30 minutos), que aparece sobre la base de un dolor persistente estable cuando este se encuentra reducido a un nivel tolerable (EVA < 5) mediante el uso de opioides mayores. Objetivos: el objetivo principal de este estudio fue evaluar la intensidad del DIO inducido por tratamientos oncológicos que incluyeran radioterapia (RT), tanto exclusiva como asociada a quimioterapia (RT/QT). Secundariamente, se evaluó la eficacia del tratamiento con fentanilo sublingual pautado para el control del DIO. Material y métodos: estudio observacional retrospectivo realizado en 110 pacientes reclutados en 19 Servicios de Radioterapia españoles. Los pacientes debían presentar DIO inducido por RT o RT/QT, con o sin medicación pautada y cuya intensidad fuera de una EVA > 6 en las últimas 24-48 h. Se establecieron controles en el momento basal, y a los 3, 7, 15 y 30 días. Resultados: se apreció un descenso en la media de los valores en la escala EVA según avanzó el estudio (EVA = 6 en el control 0 a EVA = 3 en el control 3), y las diferencias fueron significativas (p < 0,0001). La satisfacción con el tratamiento fue calificada como buena o excelente por el 85,3% de los pacientes y por el 92,7% de los investigadores. Conclusiones: los resultados de este estudio demuestran la eficacia del tratamiento del DIO con fentanilo sublingual en el contexto del tratamiento oncológico radioterápico, con un descenso significativo en los valores EVA frente al valor basal. La elevada satisfacción de los médicos y pacientes con este tratamiento refleja la eficacia y la comodidad del fentanilo sublingual en el control del DIO (AU)

Introduction: In the context of radiotherapy, control of breakthrough cancer pain (BTPc) is particularly challenging. BTPc has been defined by the Spanish Society of Pain (SED), the Spanish Society of Medical Oncology (SEOM) and the Spanish Society for Palliative Care (SECPAL) as a sudden and transient exacerbation of pain of great intensity (VAS > 7) and short (less than 20-30 minutes), which appears on the basis of a stable persistent pain when it is reduced to a tolerable level (VAS < 5) by using major opioids. Objectives: The main objective of this study was to assess the intensity of BTPc induced by cancer treatments that included radiotherapy (RT), both exclusive and associated with chemotherapy (RT/CT). Secondly, the efficacy of treatment was evaluated with fentanyl sublingual scheduled for BTPc control. Material and methods: Retrospective, observational study in 110 patients recruited in 19 Spanish Radiotherapy Services. Patients must have BTPc induced by RT or RT/CT, with or without medication prescribed and with an intensity outside a VAS > 6 in the last 24-48 h. Controls were established at baseline and at 3, 7, 15 and 30 days. Results: There was a decrease in mean values on the VAS scale as the study progressed (VAS = 6 in the control 0 to VAS = 3 in the control 3) and the differences were significant (p < 0.0001). Treatment satisfaction was rated as good or excellent by 85.3% of patients and 92.7% of researches. Conclusions: The results of this study demonstrate the efficacy of BTPc treatment with sublingual fentanyl in the context of the radiotherapy cancer treatment, with a significant decrease in VAS from baseline values . The high satisfaction among physicians and patients with this treatment reflects the efficacy and convenience of sublingual fentanyl in controlling BTPc (AU)

Impact of initial FDG PET/CT in the management plan of patients with locally advanced head and neck cancer

Objective. To determine the impact of initial FDG PET/CT staging on clinical stage and the management plan in patients with locally advanced head and neck cancer (LAHNC). Materials and methods. We retrospectively reviewed the records of 72 consecutive patients (2007–2010) staged with PET/CT and conventional CT with tumours of hypopharynx/larynx (26 patients, 36 %), oral cavity (17 patients, 24 %), oropharynx (16 patients, 22 %), nasopharynx (12 patients, 17 %), and others (2 %). The impact of PET/CT on management plans was considered high when PET/CT changed the planned treatment modality or treatment intent, and intramodality changes were considered as minor changes with low impact. Results. FDG PET/CT changed the stage in 27 patients and had high impact on the management plan in 12 % of patients (detection of distant metastases in 6 patients and stage II in 2 patients). Intramodality changes were more frequent: FDG PET/CT altered the TNM stage in 18/72 (25 %) of patients, upstaging N stage in 90 % of patients with low impact. Conclusions. Initial FDG PET/CT staging not only improves stage but also affects the management plan in LAHNC patients (AU)

Final results of a phase II single-institutional trial with hyperfractionated radiation therapy (HFX) and four-weekly continuous cisplatin in locally advanced head and neck carcinoma

BACKGROUND: To evaluate the efficacy and toxicity of hyperfractionated radiation therapy and continuous infusion of cisplatin on weeks 1 and 5 in locally advanced head and neck carcinoma. METHODS: There were 53 patients: 3 (5.7 %) T2 patients, 31 T3 patients (58.4 %), and 19 T4 patients (35.8 %). Forty-one patients (77.4 %) were N-positive. According to the AJCC, 40 (75.4 %) patients had stage IV and the rest stage III. Treatment consisted of hyperfractionated radiation therapy, 120 cGy bid to a dose of 76.8-81.6 Gy, and cisplatin 20 mg/m(2)/day administered by continuous infusion over 120 h during days 1-5 and 21-25 of radiation therapy. RESULTS: Tumor response and toxicity There were 40 (75.5 %) complete responses, 6 partial responses (11.3 %), and 5 (9.4 %) non-responses or progression. Two patients were non-evaluable for response due to toxic death. All patients had some acute toxicity grade, the most frequent being mucositis (grade 3-4 in 33 patients) and epithelitis (grade 3-4 in 30 patients). Regarding late toxicity, only 2/24 long-term survivors had tracheostomy, and none of them needed enteral nutrition. Survival and local control With a median follow-up of 66 months, the 5-year overall survival rate for all the series was 49.1 % (95 % CI 58.9-39.3 %) with a median survival duration of 32.83 months. Five-year local control was 68.4 % (95 % CI 81.3-55.5 %). CONCLUSIONS: Hyperfractionated radiation therapy and continuous infusion of cisplatin during weeks 1 and 5 are an active treatment in patients with LAHNC. Nevertheless, new strategies are necessary to increase the local control rates and reduce the incidence of distant metastasis and second tumors (AU)

Analysis of biomechanical data to determine the degree of users participation during robotic-assisted gait rehabilitation.

Recent studies have shown evidence indicating that effective robotic rehabilitation is only possible when the user actively participates during training. Providing a complete effective biofeedback to the patient representing his compliance to the therapy and his performance is thought that his active participation will be enhanced significantly, thus, improving his rehabilitation. We have performed a study with the driven gait orthosis (DGO) Lokomat (Hocoma AG, Volketswil, Switzerland). The objective of the present study is the analysis of the effect of different types of participation (attention to the functional task) from subjects receiving robotic assisted gait training on the kinematic and kinetic patterns. The obtained results provide useful evidence of specific biomechanical features that can be used to design more useful, robust, focused and intuitive biomechanical biofeedback during robotic assisted gait rehabilitation in stroke survivors.

The EORTC Quality of Life questionnaire for patients with colorectal cancer: EORTC QLQ-CR29 validation study for Spanish patients

INTRODUCTION: The EORTC Quality of Life (QL) Group has developed a questionnaire -the EORTC QLQ-CR29- for evaluating QL in colorectal cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQCR29 when applied to a sample of Spanish patients. MATERIALS AND METHODS: Eighty-four locally advanced rectal cancer patients in the treatment follow-up period after receiving surgery and neoadjuvant chemoradiotherapy were included in the study. Seventy subjects also had adjuvant chemotherapy. Patients completed both the EORTC QLQC30 and the QLQ-CR29 once. The psychometric evaluation of the questionnaire's structure, reliability, and convergent, divergent and known-groups validity was performed. RESULTS: Multitrait scaling analysis showed that three of the multi-item scales met the standards of convergent and discriminant validity. These same scales reached the 0.7 Cronbach's coefficient criterion or were close to it. In both analyses exceptions were observed in the blood and mucus in stool scale. Correlations between the scales of the QLQC30 and the module were low (r<0.02) in most cases. A few areas with more related content had higher correlations (r<0.05). Group comparison analyses showed differences in QL between groups of patients based on age, comorbidity, performance status, receipt of adjuvant chemotherapy and surgery modality. CONCLUSIONS: The EORTC QLQ-CR29 is a reliable and valid instrument when applied to a sample of Spanish rectal cancer patients. These results are in line with those of the EORTC validation study (AU)
