RESUMO

BACKGROUND: There are few data comparing health-related quality of life (HRQoL) after neoadjuvant chemotherapy alone (nCT) compared with neoadjuvant chemoradiotherapy (nCRT) in patients with oesophageal cancer. METHODS: In the NeoRes trial, patients were assigned randomly in a 1 : 1 ratio to receive either cisplatin 100 mg/m2 on day 1 and an infusion of 750 mg per m2 5-fluorouracil over 24 h on days 1-5 in three 21-day cycles (nCT) or the same chemotherapy regimen, but with the addition of 40 Gy radiotherapy (nCRT). HRQoL data were collected at baseline, after neoadjuvant therapy and at 1, 3 and 5 years after surgery. The European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 and disease-specific modules were used. RESULTS: Of 181 patients randomized, 165 were included in the analysis of HRQoL. In a direct comparison between the allocated treatments, odynophagia after completion of neoadjuvant therapy but before surgery (P = 0·047) and troublesome coughing at 3 years' follow-up (P = 0·011) were more pronounced in the nCRT arm. In the longitudinal analyses within each treatment arm, a large deterioration in HRQoL was noted at 1 year. Some recovery was seen in both arms over time but, after 3 and 5 years, patients in the nCRT arm reported more symptoms compared with baseline than patients in the nCT arm. CONCLUSION: HRQoL after multimodal treatment for cancer of the oesophagus or gastro-oesophageal junction was impaired and more pronounced in patients who underwent nCRT, with only partial recovery over time.


ANTECEDENTES: Se dispone de poca información sobre la calidad de vida relacionada con la salud (health-related quality of life, HRQOL) en pacientes con cáncer de esófago después de quimioterapia neoadyuvante sola en comparación con quimiorradioterapia neoadyuvante. MÉTODOS: En el ensayo NeoRes, los pacientes fueron asignados de forma aleatoria 1:1 a tratamiento con cisplatino 100 mg/m2 en el día uno y 5-Fluorouracilo 750 mg/m2 /infusión de 24 horas en los días 1-5 en tres ciclos de 21 días (nCT) o al mismo régimen de quimioterapia, pero con la adición de radioterapia 40 Gy (nCRT). Los datos de HRQOL se recogieron al inicio, tras el tratamiento neoadyuvante y al cabo de 1, 3 y 5 años tras la cirugía. Se utilizaron los cuestionarios QLQ-C30 de la European Organisation for Research and Treatment of Cancer (EORTC) y los módulos específicos para la enfermedad. RESULTADOS: De 181 pacientes aleatorizados, 165 fueron incluidos en el análisis de la HRQOL. En la comparación directa entre los tratamientos asignados, la odinofagia tras terminar nCRT pero antes de la cirugía (P = 0,047) y la tos molesta a los 3 años de seguimiento (P = 0,011), fueron más acentuadas en el brazo de nCRT. En el análisis longitudinal dentro de cada rama de tratamiento hubo un fuerte deterioro en la HRQOL al año. Se observó cierta recuperación en ambas ramas con el tiempo, pero a los 3 y 5 años de seguimiento, los pacientes de la rama de nCRT describieron más síntomas en comparación con la situación de inicio que los pacientes de la rama de nCT. CONCLUSIÓN: La HRQOL después del tratamiento multimodal del cáncer de esófago o de la unión gastroesofágica se ve afectada, siendo dicha afectación más pronunciada en pacientes que recibieron nCRT, recuperándose solo parcialmente con el tiempo.

RESUMO

OBJECTIVES: MUNIX (motor unit number index), derived from the compound muscle action potential (CMAP) and surface EMG interference pattern (SIP) has become popular as a substitute for motor unit number estimation (MUNE). This study was undertaken to determine why, in recent recordings from amyotrophic lateral sclerosis (ALS) patients and healthy controls, we found that MUNIX values resembled CMAP amplitudes more closely than MUNE values. METHODS: The relationship between MUNIX and CMAP and SIP amplitudes was investigated by a theoretical analysis and by reanalysing the data from the previous study. RESULTS: Theory indicates that when motor unit potentials overlap extensively, information about motor unit size and number is lost, and MUNIX depends only on CMAP area and power. Accordingly, MUNIX values were found to be sensitive to changes in CMAP amplitude but insensitive to changes in SIP amplitude. The reproducibility of MUNIX measurements in healthy controls was found to depend almost entirely on correlation with CMAP properties. CONCLUSIONS: MUNIX gives misleading information about motor unit numbers in healthy controls, and provides little information about loss of motor units in ALS patients beyond that given by simple CMAP amplitude measurements. SIGNIFICANCE: MUNIX should not be interpreted as a MUNE method.

RESUMO

Dysphagia is the most significant symptom in patients with esophageal cancer. There are different therapeutic interventions designed to relieve dysphagia, but few studies have addressed the effects of neoadjuvant therapy. The aim of this study is to compare the effects on dysphagia of neoadjuvant chemotherapy (nCT) versus neoadjuvant chemoradiotherapy (nCRT) and further to study the association between dysphagia response and histological response. Patient reported swallowing function was a secondary endpoint in the NeoRes trial, in which patients were randomized between neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy. Patients completed dysphagia questionnaires before the start and after neoadjuvant therapy, using the European Organization for Research and Treatment of Cancer (EORTC) esophageal cancer modules QLQ-OES24/OG25. Chirieac tumor regression grade (TRG) was used to assess the histological response. Out of 181 patients were randomized, of whom 87% completed the dysphagia questionnaires before and 73% after neoadjuvant treatment. Patient characteristics were similar between the treatment arms. Among patients reporting dysphagia at baseline, neoadjuvant therapy improved dysphagia in both arms. The mean dysphagia score after neoadjuvant treatment was significantly lower after nCT compared to after nCRT (P = 0.022). The reported dysphagia did not differ between those with a complete histological response (TRG 1) and those without any response at all (TRG 4) (P = 0. 583).

RESUMO

NeoRes I is a randomized phase II trial comparing neoadjuvant chemoradiotherapy with neoadjuvant chemotherapy in the treatment of resectable cancer of the esophagus or gastroesophageal junction. Patients with biopsy-proven adenocarcinoma or squamous cell carcinoma, T1N1 or T2-3N0-1 and M0-M1a (AJCC 6th ed.), were randomized to receive three 3-weekly cycles of cisplatin 100 mg/m2 day 1 and fluorouracil 750 mg/m2/24 hours, days 1-5 with or without the addition of concurrent radiotherapy 40 Gy, 2 Gy/fraction, 5 days a week, followed by esophageal resection with two-field lymphadenectomy. Primary endpoint was complete histopathological response rate in the primary tumor. Survival and recurrence patterns were evaluated as secondary endpoints. Between 2006 and 2013, 181 patients were enrolled in Sweden and Norway. All three chemotherapy cycles were delivered to 73% of the patients allocated to chemoradiotherapy and to 86% of the patients allocated to chemotherapy. 87% of those allocated to chemoradiotherapy received full dose radiotherapy. 87% in the chemoradiotherapy group and 86% in the chemotherapy group underwent tumor resection. Initial results showed that patients allocated to chemoradiotherapy more often responded with complete histopathological response in the primary tumor (28% vs. 9%). Treatment-related complications were similar between the groups although postoperative complications were more severe in the chemoradiotherapy group. This article reports the long-term results. Five-year progression-free survival was 38.9% (95% CI 28.9%-48.8%) in the chemoradiotherapy group versus 33.0% (95% CI 23.6%-42.7%) in the chemotherapy group, P = 0.82. Five-year overall survival was 42.2% (95% CI 31.9%-52.1%) versus 39.6% (95% CI 29.5%-49.4%), P = 0.60. There were no differences in recurrence patterns between the treatment groups. This is to our knowledge that the largest completed randomized trial comparing neoadjuvant chemotherapy with neoadjuvant chemoradiotherapy followed by esophageal resection in patients with cancer in the esophagus or gastroesophageal junction. Despite a higher tumor tissue response in those who received neoadjuvant chemoradiotherapy, no survival advantages were seen. Consequently, the results do not support unselected addition of radiotherapy to neoadjuvant chemotherapy as a standard of care in patients with resectable esophageal cancer.

RESUMO

OBJECTIVE: To compare the diagnostic utility of motor unit number estimation (MUNE) methods to motor unit potential (MUP) analysis in amyotrophic lateral sclerosis (ALS). METHODS: Twenty-five patients (1 definite, 11 probable, 9 possible ALS and 4 progressive muscular atrophy) and 22 healthy controls were prospectively included. Quantitative MUP analysis and three MUNE methods; Multiple Point Stimulation MUNE (MPS), Motor Unit Number Index (MUNIX) and MScanFit MUNE (MScan) were done in abductor pollicis brevis muscle. The sensitivities were compared by McNemar chi-square test. MUNE, MUP and revised ALS Functional Rating Scale (ALSFRS-R) parameters were correlated by regression analysis. RESULTS: The sensitivities of MPS (76%) and MScan (68%) were higher than MUP duration (36%) and amplitude (40%) in detecting motor unit loss (p < 0.05). MUNE methods increased the categorical probability from possible to probable ALS in 4 patients (16%). There was only significant correlation between ALSFRS-R and MScan (r = 0.443, p = 0.027) among the electrophysiological tests. MUNE methods did not correlate to MUP parameters. CONCLUSIONS: MUNE methods are more sensitive in showing abnormality than MUP analysis. SIGNIFICANCE: MUNE methods, in particular MScan, may have the potential to be implemented in the clinical practice for diagnosis and follow-up of neuromuscular disorders particularly ALS.

RESUMO

OBJECTIVE: To examine inter- and intra-rater reproducibility and sensitivity to motor unit loss of a novel motor unit number estimation (MUNE) method, MScanFit MUNE (MScan), compared to two traditional MUNE methods; Multiple point stimulation MUNE (MPS) and Motor Unit Number Index (MUNIX). METHODS: Twenty-two ALS patients and 20 sex- and age-matched healthy controls were included. MPS, MUNIX, and MScan were performed twice each by two blinded physicians. Reproducibility of MUNE values was assessed by coefficient of variation (CV) and intra class correlation coefficient (ICC). Ability to detect motor unit loss was assessed by ROC curves and area under the curve (AUC). The times taken for each of the methods were recorded. RESULTS: MScan was more reproducible than MPS and MUNIX both between and within operators. The mean CV for MScan (12.3%) was significantly lower than for MPS (24.7%) or MUNIX (21.5%). All methods had ICC>0.94. MScan and Munix were significantly quicker to perform than MPS (6.3mvs. 13.2m). MScan (AUC=0.930) and MPS (AUC=0.899) were significantly better at discriminating between patients and healthy controls than MUNIX (AUC=0.831). CONCLUSIONS: MScan was more consistent than MPS or MUNIX and better at distinguishing ALS patients from healthy subjects. SIGNIFICANCE: MScan may improve detection and assessment of motor unit loss.

RESUMO

BACKGROUND: Neoadjuvant therapy improves long-term survival after oesophagectomy, treating oesophageal cancer, but the evidence to date is insufficient to determine which of the two main neoadjuvant therapy types, chemotherapy (nCT) or chemoradiotherapy (nCRT), is more beneficial. We aimed to compare the effects of nCT with those of nCRT. PATIENTS AND METHODS: This multicentre trial, which was conducted in Sweden and Norway, recruited 181 patients with carcinoma of the oesophagus or the gastro-oesophageal junction who were candidates for curative-intended treatment. The primary end point was histological complete response after neoadjuvant treatment, which has been shown to be correlated with increased long-term survival. Study participants were randomized to nCT or nCRT, followed by surgery with two-field lymphadenectomy. Three cycles of platin/5-fluorouracil were administered in both arms, whereas 40 Gy of concomitant radiotherapy was added in the nCRT arm. RESULTS: The trial met the primary end point, histological complete response being achieved in 28% after nCRT versus 9% after nCT (P = 0.002). Lymph-node metastases were observed in 62% in the nCT group versus 35% in the nCRT group (P = 0.001). The R0 resection rate was 87% after nCRT and 74% after nCT (P = 0.04). There was no difference in overall survival between the treatment arms. CONCLUSION: The addition of radiotherapy to neoadjuvant chemotherapy results in higher histological complete response rate, higher R0 resection rate, and a lower frequency of lymph-node metastases, without significantly affecting survival.

RESUMO

OBJECTIVE: To compare the incidence and severity of postoperative complications after oesophagectomy for carcinoma of the oesophagus and gastro-oesophageal junction (GOJ) after randomized accrual to neoadjuvant chemotherapy (nCT) or neoadjuvant chemoradiotherapy (nCRT). BACKGROUND: Neoadjuvant therapy improves long-term survival after oesophagectomy. To date, evidence is insufficient to determine whether combined nCT, or nCRT alone, is the most beneficial. METHODS: Patients with carcinoma of the oesophagus or GOJ, resectable with a curative intention, were enrolled in this multicenter trial conducted at seven centres in Sweden and Norway. Study participants were randomized to nCT or nCRT followed by surgery with two-field lymphadenectomy. Three cycles of cisplatin/5-fluorouracil was administered in all patients, while 40 Gy of concomitant radiotherapy was administered in the nCRT group. RESULTS: Of the randomized 181 patients, 91 were assigned to nCT and 90 to nCRT. One-hundred-and-fifty-five patients, 78 nCT and 77 nCRT, underwent resection. There was no statistically significant difference between the groups in the incidence of surgical or nonsurgical complications (P-value = 0.69 and 0.13, respectively). There was no 30-day mortality, while the 90-day mortality was 3% (2/78) in the nCT group and 6% (5/77) in the nCRT group (P = 0.24). The median Clavien-Dindo complication severity grade was significantly higher in the nCRT group (P = 0.001). CONCLUSION: There was no significant difference in the incidence of complications between patients randomized to nCT and nCRT. However, complications were significantly more severe after nCRT. REGISTRATION TRIAL DATABASE: The trial was registered in the Clinical Trials Database (registration number NCT01362127).

RESUMO

In a retrospective review, in order to describe the palliative care and prognosis of patients with advanced cancer of the esophagus, the clinical characteristics and the treatment modalities applied were explored in relation to survival and symptom relief for 261 patients treated without curative potential. The data were obtained from a study of all patients with cancer of the esophagus treated at the Norwegian Radium Hospital in the 10-year period from 1990 to 1999. Medical data of the patients were reviewed and missing clinical information was retrieved from local hospitals and general practitioners. The patients were divided into three groups based upon the overall survival from start of treatment to death. Survival ≤3 months is in this paper, defined as 'short,' while survival > 6 months is defined as 'long.' Median survival for the total group of patients was 4 months. The 1-, 2-, and 3-year survival was 8%, 3%, and 1%, respectively. Patients with short survival (n= 107) had more advanced disease, lower performance status, and more dysphagia, weight loss, and pain and used more analgesics than patients with long survival (n= 91). Tumor characteristics such as localization, tumor length, and histology were not significantly associated with survival. This result was confirmed in a logistic regression analysis (with backward stepwise elimination) including sex, age, clinical stage, tumor length, tumor localization, histology, performance status, dysphagia, weight loss, and pain, where clinical stage, performance status, weight loss, and pain were included in the final model. A large variety of first-line palliative treatments were applied within the studied time period; external radiotherapy ± brachytherapy (n= 149), brachytherapy alone (n= 44), endoluminal stent (n= 28), laser evaporization (n= 8), chemotherapy (n= 5), and best supportive care only (n= 27). There were no clear differences in the effect on dysphagia between the modalities. Fourteen percent of the patients had treatment related complications. In conclusion, symptoms, performance status, and use of analgesics seemed to better prognosticate survival than tumor characteristics other than stage of disease. Our study reveals that knowledge about prognostic factors is crucial for the choice of palliative treatment. Even though all of the different treatment modalities seemed to provide relief of dysphagia, several other factors should be considered when deciding which treatment modality to offer. The time to onset of relief, duration of response, level of complications, and time spent in hospital should be a part of the decision-making process when selecting the appropriate treatment.

RESUMO

To be able to make suitable exercise intervention programmes for cancer survivors, we need more information about exercise preferences. The primary aim of the study was to investigate the interest and preferences for exercise among Norwegian cancer survivors. A secondary aim was to identify demographic and medical characteristics associated with interest in exercise counselling. A questionnaire was completed by 1284 cancer survivors. Overall, 76% of participants were interested or maybe interested in receiving exercise counselling at some point during their cancer experience. Logistic regression analyses indicated that the interest in exercise counselling in men was associated with younger age, presence of comorbidity and having received chemotherapy. In women, the interest was associated with younger age, higher education and change in physical activity level. The participants preferred face-to-face exercise counselling with an exercise specialist from a cancer centre, at a hospital, immediately after treatment. Most cancer survivors were interested in an exercise programme, walking as activity, at moderate intensity and they wanted to start immediately after treatment. The knowledge from this study can contribute to make suitable physical rehabilitation available to cancer patients in the future.

RESUMO

AIMS: To evaluate possible differences in effect on recurrence-free survival (RFS) and overall survival (OS) in node positive postmenopausal breast cancer patients receiving Tamoxifen or cyclic Tam and Megestrol acetate as adjuvant treatment. METHODS: Between 1989 and 1994, 489 patients with pT(1-2)pN+ hormone receptor positive or unknown tumours were included in a randomized national multicenter study to receive either Tam alone or cyclic Tam (8 weeks) and MA (8 weeks) for 2 years. Final follow-up was completed as of June 2002. Time from start of treatment to first recurrence and novel primary breast tumour, overall survival and cancer specific survival were estimated. RESULTS: No differences in RFS, OS or cancer specific survival were observed between the two treatment groups. CONCLUSIONS: Adjuvant treatment used as standard Tam alone, compared to Tam and MA, as employed in this group of patients gave similar outcomes. Side effects that led to cessation of study medication were observed in both arms.

RESUMO

BACKGROUND: To quantify the long-term risk of second cancers (SCs) up to 30 years after primary treatment for Hodgkin's disease (HD) Material and methods In the period 1968 to 1985, an unselected population of 1024 patients started treatment for HD at the Norwegian Radium Hospital (NRH) and were followed for SC from 1969 through 1998 by The Norwegian Cancer Registry. The median age at diagnosis of HD was 40 years, and the median time at follow-up was 14 years. RESULTS: Of 197 SCs, 14 were acute non-lymphocytic leukemia (ANLL), 31 non-Hodgkin's lymphoma (NHL) and 152 solid cancers. The standardized incidence ratio (SIR) was significantly increased for SCs as a group, and for the subgroups ANLL, NHL, lung cancer, breast cancer, stomach cancer and melanoma. ANLL was related to heavy treatment with chemotherapy (CT) and combined CT and radiotherapy (RT), NHL was not treatment related, and solid tumors were related to radiotherapy only or combined RT and CT. The SIR of ANLL and NHL reached a peak between 5 and 10 years after treatment. Solid and non-solid tumors increased with young age at diagnosis of HD and solid tumors increased with follow-up time up to 28 years CONCLUSION: In a long-term follow-up study of HD patients of all ages, the SIR of solid tumors was high in patients treated at young age and decreased with increasing age. Most solid tumors had started within or at the edge of the irradiated field, and SIR of solid tumors increased even 20-30 years after diagnosis.

RESUMO

AIMS: To evaluate possible differences in effect on time to recurrence and overall survival in node positive pre-menopausal breast cancer patients (age < or = 50 years) receiving LHRH analogue or tamoxifen as adjuvant endocrine treatment. METHODS: Between January 1989 and July 1994, 320 patients with node positive (pN(+)) and hormone receptor positive or receptor status unknown tumors were included and randomized in a national multicenter study to receive either tamoxifen or goserelin as adjuvant treatment for two years. Primary surgical treatment was employed according to current standards. Final follow-up was completed as of December 2000. Time to events were estimated by the Kaplan-Meier method, and compared by the log rank test. Relative risks were estimated by the Cox's proportional hazards model. RESULTS: No differences in time to first recurrence or overall survival were observed between treatment groups. Proportions of patients in each group having a second breast cancer were also similar. CONCLUSIONS: Standard adjuvant treatment with tamoxifen as compared to adjuvant LHRH analogue therapy employed in this group of breast cancer patients gave similar outcomes, but the number of patients was too small to formally exclude a potentially clinically relevant difference in survival.

RESUMO

Na sucrose octasulfate (Na SOS) was tested for ability to relieve radiation-induced acute skin and mucosal reactions in patients with head and neck cancer. Sixty patients were included in this prospective, double-blind, randomized study. Skin and mucosal reactions were scored using several variables. No statistically significant difference was found between the results with Na SOS and those with placebo for any of the variables, with the exception of skin desquamation, which showed a significant difference in the placebo group. The most likely explanation for this is that the Na SOS gel itself left behind a flaky layer that was difficult to distinguish from radiation-induced flaking. In conclusion, we cannot recommend Na SOS in the routine management of radiation-induced skin and mucosal reactions.

RESUMO

A retrospective comparison of treatment policies in two institutions revealed a change in the reliance on radiotherapy. Since 1978, high-energy, high-dosage radiotherapy has played a prominent role in the primary therapy of squamous cell carcinoma of the supraglottic larynx. Statistically, the overall determinate survival rate has improved compared with results during the preceding period, but the death rate from intercurrent disease and second primary cancers has remained unchanged. Improved cancer control and patient survival were restricted to clinical tumor stages III, T4N0, and T4N1. The choice of primary therapy and the radiation dose and fractionation pattern were important variables influencing the survival. A description of the data is followed by a critical analysis of the significance of the findings, in view of the fact that the treatments were performed in two different institutions at different time periods.

RESUMO

Retrospective analysis of patient records at two hospitals was performed with the principal goal of clarifying the role of primary radiotherapy ill patients with squamous cell carcinoma of the supraglottic larynx. Primary surgery was frequently performed during the first period from 1958 to 1978. Primary radiotherapy with surgery in reserve was the prevailing therapy during the second period from 1978 to 1993. Fewer recurrences were observed during the second period. The improved results were apparent mainly in patients with the more advanced stages (III, T4N0 and T4N1). Analysis of many factors suggest that the more frequent choice of primary radiotherapy with surgery in reserve, or applied as preoperative treatment, with optimal dosage and technique, might have contributed to the improved results.

RESUMO

In the ICD-9 system, carcinomas of the nasal vestibule are classified together with carcinomas in the nasal cavity. As a rule, however, they are squamous cell carcinomas derived from the skin, and thus prognosis is better than in the case of squamous cell carcinomas derived from the mucosa of the nasal cavity. The article highlights essential features of brachytherapy. The authors present a critical assessment of the criteria for staging, and describe a specific patient material. Based on clinical experience and theoretical considerations, brachytherapy alone is recommended for T1-3 N0 tumours. In the case of T4 tumours external radiation therapy and brachytherapy combined is recommended for the primary tumour, with prophylactical irradiation towards regional lymph nodes.

RESUMO

After completed radiotherapy, 24 in-patients and 25 out-patients enrolled at the Department of Otolaryngology, National Hospital, were randomised to either tailored dietary information and instruction by a clinical nutritionist or regular dietary information from a nurse. At the six weeks follow-up examination the incidence of malnutrition, as evaluated by anthropometry and routine blood analyses, was lower among the patients who had been given intensive information than those who had received regular information (p < 0.05). Out-patients lost more weight than in-patients did (p < 0.05). The in-patients randomised to intensive dietary information were the only ones who did not lose weight. This study indicates a beneficial effect of intensive dietary advice in order to improve nutritional status after radiation treatment.
