Fatigue in cancer patients.

In this paper an overview is presented on what is currently known of fatigue in cancer. Fatigue is considered to be a multi-dimensional concept, that should be measured as such. However, fatigue has been assessed mostly by single items in general symptom checklists. The few specific instruments that have been used in cancer patient populations are discussed. The majority of cancer patients, about 70%, report feelings of fatigue during radio- or chemotherapy. Follow-up results show that, at least for some diagnoses, patients remain fatigued long after treatment has ended. Somatic and psychological mechanisms that have been proposed to explain fatigue are discussed. It is argued that the significance of the results obtained on fatigue as a symptom in cancer depends on comparison with other patient and non-patient populations. Also the occurrence of a response-shift has to be considered, leading to under reporting of fatigue. Finally, possible interventions to decrease feelings of fatigue are presented

Fatigue and radiotherapy: (B) experience in patients 9 months following treatment.

Little is known regarding the prevalence and course of fatigue in cancer patients after treatment has ended and no recurrence found. The present study examines fatigue in disease-free cancer patients after being treated with radiotherapy (n = 154). The following questions are addressed. First, how do patients describe their fatigue 9 months after radiotherapy and is this different from fatigue in a nonselective sample from the general population (n = 139)? Secondly, to what degree is fatigue in patients associated with sociodemographic, medical, physical and psychological factors? Finally, is it possible to predict which patients will suffer from fatigue 9 months after radiotherapy? Results indicated that fatigue in disease-free cancer patients did not differ significantly from fatigue in the general population. However, for 34% of the patients, fatigue following treatment was worse than anticipated, 39% listed fatigue as one of the three symptoms causing them most distress, 26% of patients worried about their fatigue and patients' overall quality of life was negatively related to fatigue (r = -0.46). Fatigue in disease-free patients was significantly associated with: gender, physical distress, pain rating, sleep quality, functional disability, psychological distress and depression, but not with medical (diagnosis, prognosis, co-morbidity) or treatment-related (target area, total radiation dose, fractionation) variables. The degree of fatigue, functional disability and pain before radiotherapy were the best predictors of fatigue at 9-month follow-up, explaining 30%, 3% and 4% of the variance respectively. These findings are in line with the associations found with fatigue during treatment as reported in the preceding paper in this issue. The significant associations between fatigue and both psychological and physical variables demonstrate the complex aetiology of this symptom in patients and point out the necessity of a multidisciplinary approach for its treatment

Accelerated high-dose radiotherapy alone or combined with either concomitant or sequential chemotherapy; treatments of choice in patients with Non-Small Cell Lung Cancer

<p>Abstract</p> <p>Background</p> <p>Results of high-dose chemo-radiotherapy (CRT), using the treatment schedules of EORTC study 08972/22973 or radiotherapy (RT) alone were analyzed among all patients (pts) with Non Small Cell Lung Cancer (NSCLC) treated with curative intent in our department from 1995–2004.</p> <p>Material</p> <p>Included are 131 pts with medically inoperable or with irresectable NSCLC (TNM stage I:15 pts, IIB:15 pts, IIIA:57 pts, IIIB:43 pts, X:1 pt).</p> <p>Treatment</p> <p>Group I: Concomitant CRT: 66 Gy/2.75 Gy/24 fractions (fx)/33 days combined with daily administration of cisplatin 6 mg/m²: 56 pts (standard).</p> <p>Group II: Sequential CRT: two courses of a 21-day schedule of chemotherapy (gemcitabin 1250 mg/m²d1, cisplatin 75 mg/m2 d2) followed by 66 Gy/2.75 Gy/24 fx/33 days without daily cisplatin: 26 pts.</p> <p>Group III: RT: 66 Gy/2.75 Gy/24 fx/33 days or 60 Gy/3 Gy/20 fx/26 days: 49 pts.</p> <p>Results</p> <p>The 1, 2, and 5 year actuarial overall survival (OS) were 46%, 24%, and 15%, respectively.</p> <p>At multivariate analysis the only factor with a significantly positive influence on OS was treatment with chemo-radiation (P = 0.024) (1-, 2-, and 5-yr OS 56%, 30% and 22% respectively).

Feasibility of transposition of the ovaries in the surgical and radiotherapeutical treatment of cervical cancer

Ovaries are seldom subject to metastases and therefore their preservation is possible in radical cervical cancer surgery. However, with postoperative radiotherapy they cannot be preserved unless they are placed outside the radiation field. The practicality of this transposition was analysed in a series of 126 patients with cervical cancer. The ovaries were transposed intraperitoneally in a lateral and cranial direction in 44 of the 64 women under the age of 50 years. In 16 of these 44 women, only one ovary could be preserved and transposed. A critical analysis was performed of the ovaries' new location by plotting their position, marked by 2 clips each, in a single pelvis. In 68% of the women at least one ovary was placed outside the radiation field. However, because of scattered radiation, i.e. 5% of the total radiation dose at a distance of 4 cm outside the radiation field, a substantial loss of ovarian function may occur. In 32% of the women at least one ovary received less than this 5%. Optimal transposition may be achieved after extension of the abdominal incision. However, this will be unnecessary in most cases, since postoperative radiotherapy will be indicated in only approximately 15% of the wome

Prognostic factors of inoperable localized lung cancer treated by high dose radiotherapy

A retrospective study was made of the results of high dose radiotherapy (greater than or equal to 50 Gy) given to 171 patients with inoperable, intrathoracic non small cell lung cancer from January 1971-April 1973. Local control was dependent on the total tumor dose: after one year local control was 63% for patients treated with greater than 65 Gy, the two year local control was 35%. If treated with less than 65 Gy the one year local control was less than or equal to 40%. Tumor doses correlated with the size of the booster field. If the size of the booster field was less than 100 cm2, the one year local control was 72%; the two year local control was 44%. Local control was also influenced by the performance status, by the localization of the primary tumor in the left upper lobe and in the periphery of the lung. Local control for tumors in the left upper lobe and in the periphery of the lung was about 70% after one year, and about 40% after two years. The one and two years survival results were correlated with the factors influencing local control. The dose factor, the localization factors and the performance influenced local control independently. Tumors localized in the left upper lobe did metastasize less than tumors in the lower lobe, or in a combination of the two. This was not true for the right upper lobe. No correlation between the TNM system, pathology and the prognosis were foun

Radiotherapy and cis-diammine dichloroplatinum (II) as a combined treatment modality for inoperable non-small cell lung cancer: a dose finding study

A dose finding study was carried out to establish the dose of cis-diammine dichloroplatinum (II), cDDP, that can be combined with high dose radiotherapy routinely in patients with inoperable non-small cell lung cancer. The patients were irradiated over a period of 2 weeks, 5 fractions a week, followed by a rest period of 14 days. Thereafter a second course of 2 weeks was given; a total dose of 55 Gy was achieved. The weekly cDDP administration in a 3 hour infusion with pre- and posthydration preceded the first day irradiation. Twenty patients were evaluable for acute toxicity. The dose limiting factor appeared to be severe nausea and vomiting, which was not responsive to anti-emetic therapy at a cDDP level of 35 mg/m2. No renal or significant hematological side effects were observed. Complete response was seen in 10 patients, using X rays and CT scans; this was confirmed by bronchoscopy with biopsies in 9 patients. Partial remission was scored in 7 patients and no change in 4 patients. cDDP as a radiosensitizer will be further studied at a dose level of 30 mg/m2 a week or 6 mg/m2 a day in a prospective, randomized EORTC Phase II stud

Feasibility of escalating daily doses of cisplatin in combination with accelerated radiotherapy in non-small cell lung cancer

The aim of this study was to determine whether it is feasible to reduce the overall treatment time from 7 to 4 weeks in patients with non-small cell lung cancer (NSCLC) receiving radiotherapy with cisplatin. This follows an EORTC phase III randomised trial (08844) in which cisplatin given before each radiation dose resulted in improved local control and survival, but which had a relatively long treatment period of 7 weeks [Schaake-Koning et al., N Engl J Med 1992, 326, 524-530]. 38 patients with confirmed NSCLC (2 stage I, 1 stage II, 18 stage IIIA, 17 stage IIIB) received a total tumour dose of 55 Gy/20 fractions/26 days, from January 1992 to March 1994. Daily fractions of 2 Gy (5 times/week) were given to the macroscopic tumour and the non-involved adjacent lymph node areas. During the same session, a dose of 0.75 Gy was given to the macroscopic tumour (simultaneous boost). Cisplatin 6 mg/m2 was administered 1-2 h before each fraction, in an escalating total dose, during week 1 in 3 patients, during weeks 1 and 2 in 6 patients, during weeks 1, 2 and 3 in 5 patients and during the whole treatment in 24 patients. 38 patients were evaluable for acute side-effects (WHO). Maximal therapy-related toxicity (WHO) was grade 3 (nausea/vomiting in 2 patients, oesophagitis in 3 patients, dyspnoea in 3 patients, cough in 1 patient). Late side-effects were evaluated in 34 patients. There was grade 2 oesophagitis in 2 patients; grade 3 toxicity in 8 patients (tiredness in 3 patients, dyspnoea in 3 patients, oesophagitis in 2 patients); grade 4 toxicity in 4 patients (dyspnoea in 3 patients, cough in 1 patient). Pulmonary fibrosis grade 3 occurred in 4 and grade 4 in 6 patients. One patient developed a severe (grade 3) radiation pneumonitis. The low incidence of acute and late side-effects with this treatment, combining daily administration of 6 mg cisplatin with radical radiotherapy using a simultaneous boost technique, indicates that escalation of the radiation dose seems feasibl
