From Cisplatin-Containing Sequential Radiochemotherapy towards Concurrent Treatment for Patients with Inoperable Locoregional Non-Small Cell Lung Cancer: Still Unanswered Questions.

Radiotherapy has been the mainstay of the treatment of stage III non-small cell lung cancer (NSCLC) patients. In the early nineties, combined treatment with chemotherapy was introduced. In 1995, a meta-analysis showed improved treatment outcome of the sequential use of radiochemotherapy (RCT) compared to radiotherapy alone, provided cisplatin was part of the chemotherapy course. Concurrent RCT compared to radiotherapy only yielded the same improvements of 4% in the 2-year and 2% in the 5-year overall survival rates. Just recently, two meta-analyses demonstrated that concurrent RCT is definitely superior to sequential RCT in terms of local control and 2-, 3-, and 5-year survival. However, several unanswered questions remain concerning the optimal chemotherapy regimen and radiotherapy doses and techniques in terms of treatment outcome and toxicity profile. Arguments supporting a daily low-dose cisplatin scheme are presented because of comparable radiosensitizing characteristics and favourable side effects. Increasing radiotherapy doses applied according to up-to-date techniques and combinations with new biologicals might lead to further treatment improvements.

Work ability and return-to-work in cancer patients.

The extent to which self-assessed work ability collected during treatment can predict return-to-work in cancer patients is unknown. In this prospective study, we consecutively included employed cancer patients who underwent treatment with curative intent at 6 months following the first day of sick leave. Work ability data (scores 0-10), clinical and sociodemographic data were collected at 6 months, while return-to-work was measured at 6, 12 and 18 months. Most of the 195 patients had been diagnosed with breast cancer (26%), cancer of the female genitals (22%) or genitourological cancer (22%). Mean current work ability scores improved significantly over time from 4.6 at 6 months to 6.3 and 6.7 at 12 and 18 months, respectively. Patients with haematological cancers and those who received chemotherapy showed the lowest work ability scores, while patients with cancer of urogenital tract or with gastrointestinal cancer had the highest scores. Work ability at 6 months strongly predicted return-to-work at 18 months, after correction for the influence of age and treatment (hazard ratio=1.37, CI 1.27-1.48). We conclude that self-assessed work ability is an important factor in the return-to-work process of cancer patients independent of age and clinical factors.

[Perspectives in the treatment of non-small cell lung cancer stage III with radiotherapy and concomitant low-dosage chemotherapy]. / Perspectieven in de behandeling van het niet-kleincellige longcarcinoom stadium III met radiotherapie en gelijktijdig gegeven laaggedoseerde chemotherapie.

Patients with a non-small cell lung cancer stage III should preferably be treated with a combination of concomitant radiotherapy and platinum-containing chemotherapy. Concomitant chemoradiation results in improved survival compared to sequential chemoradiation, although this type oftreatment is associated with higher oesophagus toxicity. With concomitant chemoradiation the chemotherapy can be added in several ways to high-dosage radiotherapy, for example in the form of 2 courses of high dose, platinum-containing polychemotherapy once every 3 weeks. Concomitant chemoradiation with just a daily low dose of cisplatin is a good alternative. In view of its low risk of haematological and renal toxicity and ototoxicity and smaller cardiac load this is the therapy of choice and is also highly suitable for elderly patients with comorbidity.

Cancer, fatigue and the return of patients to work-a prospective cohort study.

Fatigue is a highly prevalent and debilitating symptom in cancer survivors. The aim of this study was to assess the impact of fatigue and other cancer-related symptoms on the return to work of cancer survivors. A prospective inception cohort study with 12 months of follow-up was initiated. At 6 months following the first day of sick leave, levels of fatigue, depression, sleep problems, physical complaints, cognitive dysfunction and psychological distress were assessed, in addition to clinical, sociodemographic and work-related factors. Data were obtained from one academic hospital and two general hospitals in the Netherlands. 235 patients who had a primary diagnosis of cancer and underwent treatment with curative intent were included. The rate of return to work was measured at 6, 12 and 18 months. Hazard ratios (HRs) for the duration of sick leave up to 18 months following the first day of sick leave were calculated. The rate of return to work increased from 24% at 6 months to 64% at 18 months following the first day of sick leave. Fatigue, diagnosis, treatment type, age, gender, depression, physical complaints and workload were all related to the time taken to return to work. Fatigue scores were also strongly related to diagnosis, physical complaints, and depression scores. Fatigue at 6 months predicted a longer sick leave with a hazard ratio of 0.71 (95% Confidence Interval (C.I.) 0.59-0.85), adjusted for diagnosis, treatment type, age and gender. In a multivariate Cox regression analysis, diagnosis, treatment, age, physical complaints and workload remained the only significant predictors of duration of the sick leave. 64% of cancer survivors returned to work within 18 months. Fatigue levels predicted the return to work. This was independent of the diagnosis and treatment, but not of other cancer-related symptoms. Better management of cancer-related symptoms is therefore needed to facilitate the return to work of cancer patients.
