Medical and rehabilitation interventions in pediatric central nervous system radiation necrosis: A case report.

Radiation necrosis is a potentially debilitating side effect of therapy necessary to treat pediatric central nervous system tumors. Clinical signs of cerebral radiation necrosis (CRN) are similar to symptoms of disease progression and require close monitoring. The case of an infant diagnosed with a malignant rhabdoid tumor is presented to describe the medical and rehabilitation interventions implemented to address CRN. Rehabilitation providers should routinely be consulted in children with CRN as they fill a critical role in treatment, neurological symptom monitoring, and intervention planning to address family-centered functional goals.

Evaluation of Stromal Vascular Fraction Properties and Histological Changes of Regenerating Tissue during Healing of Radiation-Induced Lesions in the Rectum.

We analyzed the main properties of autologous adipose-derived stromal vascular fraction (SVF) used for the treatment of radiation-induced lesions in the rectum. No statistically significant correlation between the main characteristics of the cell product (cell number, viability) and patient's age or donor area were revealed. The stages and peculiarities of histological changes in the regenerating tissue after injection of autologous adipose tissue cells were analyzed. Morphological changes at the stages of granulation, early and complete epithelialization, and tissue maturation were described.

Voice Quality in Laryngeal Cancer Patients: A Randomized Controlled Study of the Effect of Voice Rehabilitation.

OBJECTIVES: The study aimed to investigate the short-term and long-term effects of voice rehabilitation in patients treated with radiotherapy for laryngeal cancer as measured by both the acoustic measure smoothed cepstral peak prominence (CPPS) and perceptual measures. A secondary aim was to investigate the relationship between acoustic and perceptual measures. METHODS: In total, 37 patients received voice rehabilitation post-radiotherapy and 37 patients constituted the irradiated control group. Outcome measures were mean CPPS for connected speech and ratings with the auditory-perceptual Grade, Roughness, Breathiness, Asthenia and Strain (GRBAS) scale. Outcome measures were analyzed 1 (baseline), 6, 12, and 24 months post-radiotherapy, where voice rehabilitation was conducted between the first two time-points. Additional recordings were acquired from vocally healthy participants for comparison. RESULTS: CPPS values of the voice rehabilitation group and vocally healthy group were not significantly different at 24 months post-radiotherapy. Ten out of 19 patients who received voice rehabilitation yielded a CPPS value above the threshold for normal voice 24 months post-radiotherapy, compared to 11 out of 26 in the irradiated control group. No statistically significant correlations were found between CPPS and perceptual parameters of GRBAS. CONCLUSION: Voice rehabilitation for irradiated laryngeal cancer patients may have positive effects on voice quality up to 24 months post-radiotherapy. The relationship between CPPS and GRBAS as well as the applicability of CPPS for evaluation over several points of measurement needs to be studied further.

A case report on intensive, robot-assisted rehabilitation program for brainstem radionecrosis.

INTRODUCTION: Radiotherapy is a valid treatment option for nasopharyngeal carcinoma. However, complications can occur following irradiation of the closest anatomical structures, including brainstem radionecrosis (BRN). The rehabilitation is poorly described in patients with BRN, despite its usefulness in improving functional independence in patients with brain tumors. We aimed at testing the usefulness of intensive, robot-assisted neurorehabilitation program to improve functional independence in a 57-year-old male with BRN. PATIENT CONCERNS: A 57-year-old male diagnosed with a nasopharyngeal carcinoma, received a radiation total dose of 72 Gy. Owing to the appearance of a severe symptomatology characterized by dysphagia, hearing loss, and left sided hemiparesis, the patient was hospitalized to be provided with intensive pharmacological and neurorehabilitation treatment. DIAGNOSIS: Follow-up brain magnetic resonance imaging disclosed no residual cancer, but some brainstem lesions compatible with BRN areas were appreciable. INTERVENTION: The patient underwent a 2-month conventional, respiratory, and speech therapy. Given that the patient only mildly improved, he was provided with intensive robot-aided upper limb and gait training and virtual reality-based cognitive rehabilitation for other 2 months. OUTCOMES: The patient reported a significant improvement in functional independence, spasticity, cognitive impairment degree, and balance. CONCLUSION: Our case suggests the usefulness of neurorobotic intensive rehabilitation in BRN to reduce functional disability. Future studies should investigate whether an earlier, even multidisciplinary rehabilitative treatment could lead to better functional outcome in patients with BRN.

Cost-effectiveness analysis of voice rehabilitation for patients with laryngeal cancer: a randomized controlled study.

INTRODUCTION: Voice problems are common following radiotherapy for laryngeal cancer. Few studies exist covering the effect of voice rehabilitation, and no previous studies exist regarding the cost of said rehabilitation. This randomized controlled study aimed to analyze the cost-effectiveness of voice rehabilitation after radiotherapy for patients with laryngeal cancer. MATERIAL AND METHODS: A total of 66 patients with laryngeal cancer with follow-up data 12 months post-radiotherapy were included. Patients were randomized into receiving either voice rehabilitation (n = 32) or no voice rehabilitation (n = 34). The patient outcome was measured as quality-adjusted life years (QALYs). The index range between 0 and 1, where 0 equals death and 1 represents perfect health. The QALYs were assessed with the European Organization for Research and Treatment of Cancer questionnaire QLQ-C30 mapped to EuroQoL 5 Dimension values. The cost of rehabilitation and other healthcare visits was derived from hospital systems. The patients reported the total amount of sick leave days during the first 12 months following radiotherapy. The cost-effectiveness of the voice rehabilitation was compared with no rehabilitation intervention based on the incremental cost-effectiveness ratio. RESULTS: The cost per gained QALY with voice rehabilitation compared to no rehabilitation from a societal perspective was - 27,594 € (SEK - 250,852) which indicates that the voice rehabilitation is a cost-saving alternative compared to no rehabilitation due to lower costs and a slightly better health outcome. From a healthcare perspective, the voice rehabilitation indicates a cost 60,800 € (SEK 552,725) per gained QALY. CONCLUSION: From a societal perspective, i.e., including the costs of production loss, voice rehabilitation compared to no voice rehabilitation following radiotherapy for laryngeal cancer seems to be cost-saving. When analyzing only the healthcare costs in relation to health outcomes, voice rehabilitation indicates an incremental cost of 60,800 € per gained QALY, which is just above the threshold of the maximum willingness to pay level.

Voice rehabilitation for laryngeal cancer after radiotherapy: a systematic review and meta-analysis.

PURPOSE: We aimed to determine whether voice rehabilitation after radiotherapy improves the quality of life (QOL), voice function, and self-rated voice function in patients with laryngeal cancer. METHODS: We searched CENTRAL, MEDLINE, EMBASE, PEDro, and World Health Organization International Clinical Trials Registry Platform for randomized controlled trials published between inception and October 2018. The primary outcome was QOL, adverse events and mortality. Secondary outcomes included voice function and self-rated voice function. The quality of evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation approach. RESULTS: Three trials (enrolling 122 patients) compared voice rehabilitation to usual care or no intervention after radiotherapy. Voice rehabilitation did not significantly improve any QOL scores. Data on adverse events and mortality were not available in any of the trials. Voice rehabilitation did not improve any voice function scores, such as jitter (mean difference: - 0.48 [- 1.27 to 0.32]), shimmer (mean difference: - 0.04 [- 0.27 to 0.19]), maximum phonation time (mean difference: 1.54 [- 1.13 to 4.22]), and the grade, roughness, breathiness, asthenia, and strain scale (mean difference: - 0.39 [- 2.59 to 1.80]). Voice rehabilitation also did not improve the voice handicap index, which was used as a self-rated voice function score (mean difference: 5.54 [- 2.07 to 13.16]). The certainty of the evidence was graded as low for primary and secondary outcomes. CONCLUSION: Voice rehabilitation for patients with laryngeal cancer after radiotherapy might not improve QOL, voice function, and self-rated voice function. Pre-specified voice rehabilitation programs may not be necessary for all patients with laryngeal cancer after radiotherapy.

Submandibular function recovery after IMRT in head and neck cancer: A prospective dose modelling study.

PURPOSE: To estimate the dose response relationship for submandibular gland (SMG) recovery using salivary scintigraphy in patients diagnosed with head and neck cancer treated with curative image guided chemoradiation. MATERIAL AND METHODS: Ninety newly diagnosed head and neck cancer patients (T1-3, N0-2c, M0) treated with intensity modulated radiotherapy on a prospective clinical trial were assessed for salivary toxicity at predefined intervals using dynamic salivary scintigraphy. The SMG function was measured using salivary excretion fraction (SEF) ratios at baseline and 6 monthly. Tolerance dose (TD) 50 for submandibular gland was estimated from dose response curves. RESULTS: The mean SEF ratio of 180 SMGs decreased at 6 months with a nadir at 12 months after treatment (SEF ratio 15%) and progressively recovered over time reaching 38% over 24 months. There was significant inverse correlation between SEF ratio and mean SMG dose at 6 months (r = -0.18, p = 0.04); 12-months (r = -0.36, p < 0.001); 18-months (r = -0.48, p < 0.001); 24-months (r = -0.42, p < 0.001); and more than 24-months (r = -0.56, p < 0.001). The estimated TD 50 values at 1 year and 2 year post treatment were 36 Gy and 44 Gy respectively with SEF ratio of ≤45% used to define severe xerostomia. For every 1 Gy reduction in mean dose below 54 Gy, there is 2-2.5% reduction in the probability of severe xerostomia. CONCLUSION: The submandibular gland function declines after radiotherapy with a nadir at 12 months and there is incomplete recovery over time with continued improvement over 24 months. The TD 50 at 1 year and 2 year was 36 Gy and 44 Gy with a 2-2.5% reduction in the probability of severe xerostomia for every 1 Gy reduction in mean dose.

Speech-language therapy program for mouth opening in patients with oral and oropharyngeal cancer undergoing adjuvant radiotherapy: a pilot study. / Programa terapêutico fonoaudiológico para abertura de boca em pacientes com câncer de boca e orofaringe em radioterapia adjuvante: estudo piloto.

Purpose Assess the effectiveness of an orofacial myofunctional therapeutic program in patients with oral or oropharyngeal cancer submitted to adjuvant radiotherapy through pre- and post-program comparison of maximum mandibular opening. Methods Prospective study involving five adult patients and five elderly patients postoperatively to oral cavity/oropharynx surgery who were awaiting the beginning of radiotherapy or had undergone fewer than five treatment sessions. The study participants had their maximum jaw opening measured using a sliding caliper at the beginning and end of the program. Two mobility exercises and three mandibular traction exercises were selected and weekly monitored presentially for 10 weeks. Descriptive data and pre- and post-therapy comparative measures were statistically analyzed using the Wilcoxon test. Results Ten patients (two women and eight men) with mean age of 58.4 years, median of 57.0 years, completed the therapeutic program. They presented mean maximum mandibular opening of 31.6 ± 11.7 and 36.4 ± 8.0 mm pre- and post-therapy, respectively (p =0.021). Conclusion The proposed orofacial myofunctional therapeutic program increased the maximum jaw opening of patients referred to adjuvant radiotherapy for oral cavity or oropharynx cancer treatment.

Dilator Use After Vaginal Brachytherapy for Endometrial Cancer: A Randomized Feasibility and Adherence Study.

BACKGROUND: Vaginal brachytherapy, a common treatment of endometrial cancer, is associated with high rates of vaginal stenosis. Recommendations for vaginal dilator use to minimize stenosis generally include 3 times per week for approximately 10 minutes per use. However, adherence rates range widely and are generally well less than 50%. OBJECTIVES: The aims of this study were to assess feasibility of recruitment to a study of dilator use and test a theoretically driven enhanced educational program (EEP) to increase adherence. METHODS: Eligibility included women treated with postoperative vaginal brachytherapy for stage I to IIIc endometrial cancer. Patients were randomized to either nurse-delivered standard institutional instruction or EEP. RESULTS: Of eligible patients, 76% consented, 42 were randomized, and 69% completed the 6-month assessment. Mean age was 58.2 years; 48% were sexually active. There was no difference in adherence between arms. Overall, 20% and 8.3% were adherent to the prescribed use of 3 times per week, and 64% and 16% were adherent to use at least once per week at 6 weeks and 6 months, respectively. Adherence was greater among those motivated by vaginal health and having lower body mass index. Nonadherence was significantly higher among those who are college educated, in the EEP group, and with higher weight. CONCLUSIONS: Feasibility of recruitment into a study of vaginal dilator use was high. Adherence was low, and there was no difference between groups. Adherence to vaginal dilator use requires novel interventions to test. IMPLICATIONS FOR PRACTICE: Nursing education that includes how dilators may maintain vaginal health may improve use because it was a motivator for adherence in this study.

Voice Range Profile and Health-related Quality of Life Measurements Following Voice Rehabilitation After Radiotherapy; a Randomized Controlled Study.

PURPOSE: The aim of the present study was to investigate the effects of voice rehabilitation in patients treated with radiotherapy for laryngeal cancer. METHOD: A total of 42 patients with laryngeal cancer who are treated with radiotherapy with curative intent participated in a randomized controlled study. The collected data were voice range profiles (VPRs) and patient-reported outcome (PRO) instruments for measurement of self-perceived communication function (Swedish Self-Evaluation for Communication Experiences after Laryngeal cancer (S-SECEL)) and health related quality of life (HRQL) (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30/Head and Neck module). Data were collected 1 month (pre voice rehabilitation), 6 months, and 12 months postradiotherapy. Of the patients, 19 received voice rehabilitation, whereas 23 constituted a control group. RESULTS: There were several statistically significant improvements in the study group concerning the HRQL and self-perceived communication function. The largest improvements occurred between occasions 1 (prevoice rehabilitation) and 2 (6-month postradiotherapy) and then remained constant. VRP area demonstrated a statistically significant difference when comparing changes over time, where the study group improved more than the control group. CONCLUSION: HRQL and self-perceived communication function showed improvement in the study group and trends of impairment in the control group. This result might suggest that it would be beneficial for the patients as well as in a health economic perspecitve, to receive voice rehabilitatiom to make a faster improvement of the HRQL and self-perceived communication function.

A nurse-led sexual rehabilitation intervention after radiotherapy for gynecological cancer.

PURPOSE: Although vaginal dilator use after combined pelvic radiation therapy and brachytherapy (RT/BT) is recommended to prevent vaginal shortening and stenosis, women fail to use them and experience sexual problems. A nurse-led sexual rehabilitation intervention targeting sexual recovery and vaginal dilatation was developed. Its feasibility was investigated during a prospective, longitudinal, observational pilot study. METHODS: Four oncology nurses were specifically trained to conduct the intervention. Gynecologic cancer patients treated with RT/BT were assessed using (i) questionnaires on frequency of dilator use (monthly), sexual functioning, and sexual distress (at baseline and 1, 6, and 12 months) and psychological and relational distress (at 1, 6, and 12 months); (ii) semi-structured interviews (between 6 and 12 months); and (iii) consultation recordings (a random selection of 21 % of all consults). RESULTS: Twenty participants were 26-71 years old (mean = 40). Eight participants discontinued participation after 3 to 9 months. At 6 months after RT, 14 out of 16 (88 %), and at 12 months 9 out of 12 (75 %), participants dilated regularly, either by having sexual intercourse or by using dilators. Sexual functioning improved between 1 and 6 months after RT, with further improvement at 12 months. Most participants reported that the intervention was helpful and the nurses reported having sufficient expertise and counseling skills. CONCLUSIONS: According to the pilot results, the intervention was feasible and promising for sexual rehabilitation and regular dilator use after RT. Its (cost-)effectiveness will be investigated in a randomized controlled trial.

Clinical Evaluation and Management of Radiation Fibrosis Syndrome.

Radiation fibrosis syndrome describes the multiple neuromuscular, musculoskeletal, visceral, and other late effects that result from radiation-induced fibrosis. Radiation can damage the spinal cord, nerve roots, plexus, local peripheral nerves, and muscles within the radiation field. This constellation is known as a "myelo-radiculo-plexo-neuro-myopathy" and can result in pain, sensory loss, weakness, and other signs and symptoms. Although there is no curative treatment for radiation damage, supportive management of symptoms can be helpful in restoring and maintaining function and quality of life.

Krüppel-like Factor 4 Modulates Development of BMI1(+) Intestinal Stem Cell-Derived Lineage Following γ-Radiation-Induced Gut Injury in Mice.

In response to ionizing radiation-induced injury, the normally quiescent intestinal stem cells marked by BMI1 participate in the regenerative response. Previously, we established a protective role for Krüppel-like factor 4 (KLF4) in the intestinal epithelium where it reduces senescence, apoptosis, and crypt atrophy following γ-radiation-induced gut injury. We also described a pro-proliferative function for KLF4 during the regenerative phase post irradiation. In the current study, using a mouse model in which Klf4 is deleted from quiescent BMI1(+) intestinal stem cells, we observed increased proliferation from the BMI1(+) lineage during homeostasis. In contrast, following irradiation, Bmi1-specific Klf4 deletion leads to decreased expansion of the BMI1(+) lineage due to a combination of reduced proliferation and increased apoptosis. Our results support a critical role for KLF4 in modulating BMI1(+) intestinal stem cell fate in both homeostasis and the regenerative response to radiation injury.

Teleaudiometry as a screening method in school children

OBJECTIVE: To compare the efficacy and feasibility of teleaudiometry with that of sweep audiometry in elementary school children, using pure-tone audiometry as the gold standard. METHODS: A total of 243 students with a mean age of 8.3 years participated in the study. Of these, 118 were boys, and 125 were girls. The following procedures were performed: teleaudiometry screening with software that evaluates hearing at frequencies of 1,000, 2000 and 4000 Hz at 25 dBHL; sweep audiometry screening in an acoustic booth (20 dBHL at the same frequencies); pure-tone audiometry thresholds in an acoustic booth (frequencies of 500, 1000, 2000 and 4000 Hz); and acoustic immittance measurements. RESULTS: The diagnostic capacities of the teleaudiometry/sweep audiometry screening methods were as follows: sensitivity  ϝ  58%/65%; specificity  ϝ  86%/99%; positive predictive value  ϝ  51%/91%; negative predictive value  ϝ  89%/92%; and accuracy  ϝ  81%/92%. Teleaudiometry and sweep audiometry showed moderate agreement. Furthermore, the use of these methods in series with immittance testing improved the specificity, whereas parallel testing improved the sensitivity. CONCLUSION: Teleaudiometry was found to be reliable and feasible for screening hearing in school children. Moreover, teleaudiometry is the preferred method for remote areas where specialized personnel and specific equipment are not available, and its use may reduce the costs of hearing screening programs. .

Qualitative accounts of patients' determinants of vaginal dilator use after pelvic radiotherapy.

INTRODUCTION: Treatment with pelvic external beam radiotherapy with brachytherapy (EBRT/BT) for gynecological cancers may cause sexual dysfunction because of vaginal shortening and tightening. Regular vaginal dilator use is thought to reduce vaginal shortening and/or tightening, but compliance is poor. AIMS: This study identified determinants of patients' adherence with dilator use after EBRT/BT. METHODS: Semi-structured interviews were conducted with 30 women, aged 32-67 years, treated with EBRT/BT for gynecological cancers at two university medical centers in the past 36 months. Transcriptions were coded and analyzed with N-Vivo software. MAIN OUTCOME MEASURES: Determinants of dilator use were clustered based on the Health Action Process Approach, which describes (i) motivation processes that lead to a behavioral intention and (ii) volition processes that lead to the initiation or maintenance of actual behavior. RESULTS: Almost all women attempted to perform long-term regular vaginal dilator use. Intended dilator use was determined by the expectation that it would prevent the development of vaginal adhesions and stenosis. Planning dilator use and making it part of a routine, using it under the shower, using lubricants, a smaller dilator size, or vibrators helped women. Others reported a lack of time or privacy, forgetting, or feeling tired. Women self-regulated dilator use by rotating the dilator and timing dilator use. Influencing factors were negative emotions regarding dilator use or its hard plastic design, (being anxious for) pain or blood loss, and an association with EBRT/BT. Some women mentioned a lack of instrumental support, for example, lubricants. Others received reassurance through informational support or were supported socially. CONCLUSION: Motivation and volition processes that determined dilator use were identified and used in the development of a sexual rehabilitation intervention. It is important to provide sufficient patient information and support, and enlarge patients' perceived self-efficacy.

Survivors' experiences of dysphagia-related services following head and neck cancer: implications for clinical practice.

BACKGROUND: It is known that people with dysphagia experience a number of negative consequences as a result of their swallowing difficulties following head and neck cancer management (HNC). However their perceptions and experiences of adjusting to dysphagia in the post-treatment phase, and the services received to assist this process, has not been studied. AIMS: To explore the lived experience of people with dysphagia following non-surgical treatment for HNC and examine their perceptions of service needs. METHODS & PROCEDURES: A demographically diverse group of 24 people who had received radiotherapy for HNC in the past five years, and experienced dysphagia as a result of treatment, were recruited using maximum variation sampling. Each participant took part in a semi-structured, in-depth interview, where they reflected on their adjustment to, and recovery from dysphagia following treatment for HNC, as well as the dysphagia-related services they received during their treatment. Thematic analysis was used to analyse the transcripts and to identify key themes that emerged from the data. RESULTS: The main integrative theme was the desire for ongoing access to dysphagia-related services in order to adequately manage dysphagia. Within this integrative theme were five additional themes including: (1) entering the unknown: life after treatment for HNC; (2) making practical adjustments to live with dysphagia; (3) making emotional adjustments to live with dysphagia; (4) accessing support outside the hospital services; and (5) perceptions of dysphagia-related services. CONCLUSIONS & IMPLICATIONS: The interviews revealed the need for both greater access to services and a desire for services which address the multitude of issues faced by people with dysphagia following HNC in the post-treatment period. Speech and language therapists managing this caseload need to ensure post-treatment services are available and address not only the physical but also the emotional and psychosocial changes impacting people with dysphagia in order to assist them to adjust to, and live successfully with dysphagia. Further research should be conducted to support the development of innovative services and to highlight dysphagia-related survivorship issues to governing bodies/policy makers.

Voice outcome in patients treated for laryngeal cancer: efficacy of voice rehabilitation.

OBJECTIVE: To investigate the efficacy of voice rehabilitation regarding acoustically measured voice quality as well as self-perceived function after radiotherapy for laryngeal cancer. STUDY DESIGN: Prospective intervention study. METHODS: Twenty male patients irradiated for laryngeal cancer participated in the study. Voice recordings and self-assessment of voice function (hoarseness, vocal fatigue, and vocal loudness) were made one and 6 months after completion of radiotherapy. The recordings were analyzed with the program Praat. Ten of the patients received 10 sessions of structured voice rehabilitations between the recordings and 10 worked as a control group. RESULTS: Jitter and shimmer improved for both groups. Harmonics-to-noise-ratio and maximum phonation time improved for the patients who received voice rehabilitation while it deteriorated for the control group. The self-assessment questions about vocal fatigue and vocal loudness showed improvement for both groups while hoarseness showed no change. CONCLUSION: General improvement was seen for both the study group and the control group. Despite the lack of statistical significant difference, there are trends where greater improvement in perturbation and self-assessment measures are noted in the study group. The results suggest positive effects of voice rehabilitation in both voice quality and self-perceived function.

A randomized controlled trail of combination therapy of neuromuscular electrical stimulation and balloon dilatation in the treatment of radiation-induced dysphagia in nasopharyngeal carcinoma patients.

Dysphagia is a most common complication induced by radiotherapy in nasopharyngeal carcinoma (NPC) patients. This randomized controlled trail (RCT) was performed to evaluate the therapeutic effect of combination therapy of neuromuscular electrical stimulation (NMES) and balloon dilatation in the treatment of radiation-induced dysphagia in NPC patients. Sixty NPC patients with radiation-induced dysphagia were assigned to either the combination rehabilitation group (treatment group) or the routine rehabilitation group (control group) at random. Both groups were subjected to routine rehabilitation treatment, while the combination rehabilitation group also received combination therapy of NMES and balloon dilatation for 4 months. The water swallow test (WST) and videofluoroscopic swallowing study (VFSS) were used to evaluate the severity of dysphagia. The treatment group showed a significant improvement in swallowing function when compared with the control group. When the WST was used, the efficacy rate (percentage of patients with excellent and effective results) of treatment group was higher than that of control group (90.1 vs. 76.3%), and the difference was statistically significant (χ(2) = 8.55, p = 0.036). When the VFSS was used, the videofluoroscopy results in our study showed that the values of oral transit time (OTT), swallow reaction time (SRT), pharyngeal transit time (PTT) and laryngeal closure duration (LCD) in treatment group were notably improved when compared with those in control group. In conclusion, combination rehabilitation treatment can improve swallow function in the treatment of radiation-induced dysphagia in NPC patients.

Rehabilitación neuropsicológica en niños con tumores del sistema nervioso central y lecucemias irradiadas / No disponible

Actualmente la intervención e investigación en psicooncología pediátrica se dirige hacia la evaluación de las consecuencias de la enfermedad y los efectos secundarios de los tratamientos, y a los factores predictivos tanto de desajustes como de aspectos adaptativos a la enfermedad del paciente y de su familia. Las tasas de curación alcanzadas en la actualidad, nos permiten contar con un número considerable de supervivientes de cáncer infantil, susceptibles de ser evaluados y poder determinar así las secuelas a largo plazo de la enfermedad y sus procedimientos terapéuticos. Además de incrementar considerablemente la supervivencia, también se ha mejorado la calidad de vida de los niños, mediante el tratamiento de soporte que amortigua notablemente los efectos secundarios de los tratamientos y su toxicidad, permitiendo de este modo, junto con la intervención temprana de los equipos multidisciplinares, que el niño mantenga continuidad con sus actividades habituales, aún estando en el periodo de tratamiento. Durante la última década, diversos estudios ponen de manifiesto la ausencia de diferencias significativas entre niños enfermos oncológicos, en relación a la población de niños sanos, en cuanto al funcionamiento psicosocial se refiere. No obstante, los pacientes afectos de tumores cerebrales y leucemias u otros tumores que han recibido quimioterapia intratecal y/o irradiación cráneo-espinal, constituyen un grupo de riesgo que requiere de una evaluación y un tratamiento específico (AU)

Nowadays, intervention and research in pediatric psychooncology is leading towards evaluation of neoplastic disease and treatment consequences, as well as predictive factors of adaptative aspects related to disease and family. High rates of survival in pediatric oncology imply an important number of pediatric cancer survivors, whose psychological and neuropsychological evaluation is crucial to determine long term sequelae. Quality of survival has also improved considerably due to improvements in supportive treatment along years, decreasing acute side effects. This fact as well as early intervention by multidisciplinary teams let the child continue his/her daily activities, even during oncologic treatment. In the last decade, several studies have shown the absence of significative differences between cancer patients and their peers, as far as social functioning is concerned. Nevertheless, patients with brain tumors and leukemias treated with radiotherapy/intrathecal chemotherapy are a risk group that required a specific evaluation and treatment (AU)
