Background: In Germany at present, 64% of women and 59% of men who receive a diagnosis of cancer are still alive five years later. 45% of men and 57% of women with cancer are still of working age. Cancer can markedly harm their ability to work.
Methods: We analyzed data from selected publications to calculate the percentage of cancer patients in Germany who are now returning to work.
Results: The efficacy of oncological rehabilitation has not been demonstrated by a randomized controlled trial, nor is it clear whether the existing studies have accounted for potentially confounding variables. A combined assessment of reports from various countries reveals that 63% of cancer patients who are of working age go back to work after being unable to work for an average of five months. The situation varies markedly across countries: In Germany, the percentage of women with breast cancer who return to work is only 59%, compared to 80% in the USA and 82% in the United Kingdom. Younger and better educated patients are more likely to return to work, as are those who have received less invasive treatment with fewer complications.
Conclusion: Most cancer patients of working age go back to work, but the percentages vary widely from one country to another, perhaps reflecting differences in social systems.
Along with cardiovascular disease, malignant tumors are by a long way the most frequent cause of death in Germany. From 1980 to 2006, the number of new cases of cancer went up by 35% in women and more than 80% in men. Every other man and 43% of women must expect to develop cancer at some point in their lives (1). This trend is likely to continue in 2012. In 2007, a total of 459 000 men and women developed cancer; in 2012 the figure will be over 486 000 (1).
The mean age at diagnosis among both men and women is 69 years, but 45% of cancers in men and 57% of those in women occur before the age of 65 (1). Although the absolute rate of new cases of cancer has increased markedly in the past few decades, age-adjusted mortality in the past 30 years has gone down (Figure 1). The drop in mortality is not sex-specific, but shows the greatest effect among patients below the age of 65—those still of working age (1).
The corollary of falling cancer mortality is an increase in rates of cure or an increase in overall survival time in terms of all cancer cases. Among women
Methods
This review article is based on a selective literature search on PubMed that aimed to establish the percentage of cancer patients who return to work. Factors shown in the literature to either promote or impede returning to work were also analyzed.
The literature search included original articles in the form of retrospective analyses, meta-analyses, and reviews published in the past 10 years, which either related to several types of cancer or evaluated particular tumor entities. No information regarding correction for confounding variables was given in the publications studied.
Returning to work after cancer
A meta-analysis of 36 studies—particularly from the USA and Europe, as well as some other countries—compared 20 366 long-term survivors of cancer with 157 603 healthy people in terms of occupation, without matching. While 15.2% of the healthy probands were unemployed, the unemployment rate among the long-term survivors was 33.8%, corresponding to a relative risk of 1.37 (95% confidence interval [95% CI]: 1.21 to 1.55) (2). This resulted in tumor patients’ having a 37% higher risk of unemployment than healthy probands.
In addition to this, another large meta-analysis recently showed that almost two-thirds of all tumor patients of working age (63.5%; range: 24% to 94%) can return to their previous occupation or another one (3). This meta-analysis included 64 studies published between January 2000 and November 2009. The mean duration of inability to work was 5 months. Between 26% and 53% of patients lost their job or gave up work in the 6 years after diagnosis. By comparison to healthy probands, many tumor patients changed jobs, worked a reduced number of hours, and experienced a drop in pay (3).
The percentages of patients who return to work varies in the different social systems. To allow comparisons, these are shown for breast cancer (Table 1) (4–11). The figures show Germany (59%) at the tail end with South Korea (58%) (4, 9). There are no confirmed data relating to this fact. The most likely reason is that the German social system makes it possible to make special allowance for the health sequelae of cancer, with up to 78 weeks sick pay from the employer, sickness benefit provided by health insurance, and a partial or complete disability pension. These options do not exist for many cancer patients in other countries, and therefore financial pressures probably lead to their returning to work early.
Prognostic factors that promote or impede the return to working life are shown in Table 2. This makes clear that it is not only tumor type, cancer therapy, and the resulting physical and mental impairments that play a part—sociodemographic and work-related factors do too (4, 11–22). In terms of the percentage of patients who return to work, there are no significant differences between patients with testicular tumors or malignant melanoma and non-tumor patients (7).

tal function (28). It is noteworthy that, according to Short et al., around 73% of patients in the USA are back at work as early as the first year after completing their tumor therapy; by the fourth year after tumor diagnosis, the percentage has gone up to 84% (29).For cancer survivors, the effects of unemployment are considerable. Loss of employment often leads to reduced quality of life, reduced self-respect, and financial problems (30).
Measures promoting a return to work
Medical cancer rehabilitation
In Germany, medical rehabilitation is an integral part of the social security system, and is laid down in law (31). This gives the patients concerned a legal right to an inpatient or outpatient rehabilitation program usually lasting 3 weeks (32). Medical rehabilitation in Germany is thus fundamentally different from the systems in other European countries (33).
Medical rehabilitation in Germany is largely paid for by the statutory pension insurance scheme (Deutsche Rentenversicherung, DRV) and by the health insurance companies. In 2010, 170 662 patients went through an inpatient or outpatient cancer rehabilitation program paid for by the DRV. This equates to 18% of all rehabilitation programs, putting cancer rehabilitation in third place among other programs such as rehabilitation due to psychological disorders and orthopedic conditions. Out of all cancer rehabilitation measures, 44% were carried out in people of working age, and 2% of these were in outpatient rehabilitation. In 2007, cancer rehabilitation measures were approved for 61 902 insurees with the objective of enabling them to return to work.
Out of this group, 52% were once again able to pay their statutory pension contributions regularly because they were in work, and 17% of patients made irregular contributions. Sixteen percent of the patient received disability pension (Figure 2) (34). The most frequent users of cancer rehabilitation were breast cancer patients (26%). In second place were those with malignancies of the digestive organs (19%), followed by malignant tumors of the male genital organs (18%). Most of the cases in the last group were men with prostate cancer (34).
For the DRV, successful rehabilitation into working life is the main criterion of success (the slogan is “Reha vor Rente,” rehab before pension) (35). Financially, the DRV comes out ahead if successful rehabilitation can postpone early retirement on grounds of disability by at least 4 months (Figure 3) (34). At present there are no independent studies outside the DRV’s own dataset on this subject.
Before starting a cancer rehabilitation program, it must be tested whether a need for rehabilitation exists. Examples of the criteria by which this is decided are shown in Table 3. According to § 8 of the Rehabilitation Guideline of the Joint Federal Committee (Gemeinsamer Bundesausschuss), a need for rehabilitation exists “when, for reasons of physical, mental, or psychological impairment, restrictions of everyday activity exist that are probably not temporary, which may be expected to restrict the ability to work in the foreseeable future, or already restrict it, and which require multidimensional and interdisciplinary medical rehabilitation in addition to curative care. Such restrictions include the need for nursing care.”
In terms of the therapeutic principles of cancer rehabilitation, ident
So far, the effectiveness of cancer rehabilitation has not been proven in either national or international randomized studies. This is largely due to the fact that the rehabilitation of cancer patients differs according to public health systems around the world, and is carried out in different ways (33). While in Germany a 3-week inpatient rehabilitation program is usually the norm, in Scandinavia and the Netherlands, rehabilitation is usually on an outpatient basis in the form of long-term care provided by a multiprofessional rehabilitation team (33, 39). In the USA, likewise, outpatient rehabilitation facilities with a small inpatient capacity have developed, mostly at the national tumor cen
One area in which there is good evidence strongly relevant to cancer rehabilitation is movement therapy. A systematic review of randomized studies showed that controlled physical activities adapted to patients’ abilities can significantly improve patients’ cardiovascular fitness and physical performance after chemotherapy (e6). In addition, for patients with colorectal, prostate, or breast cancer, it was shown that a program of movement therapy reduced tumor-specific mortality (e7–e9).
Because of the positive correlation between nutritional behavior and risk of recurrence, this area is particularly important in the educative component of cancer rehabilitation. For both patients with colon cancer and those with breast cancer, cohort studies have shown that a diet rich in animal fats significantly increases the risk of recurrence (e10, e11).
The use of physiotherapy in cancer rehabilitation is another area for which there are no published randomized studies, so the evidence for it is low. However, uncontrolled studies have been cited that show an improvement in respiratory function after lung surgery or optimization of shoulder mobility after breast surgery or neck dissection (e12–e15).
In the same way there is only limited evidence to support “psycho-oncologic” therapy. In two observation studies a reduction in anxiety and depression was shown, both immediately after cancer rehabilitation and six months later (e16, e17). An important reason for psycho-oncologic treatment for depression during rehabilitation is that a meta-analysis found a statistically significant correlation between depression, tumor progression, and mortality (e18).
In view of the data situation described above, the components of cancer rehabilitation in Germany today are a program of training in dealing with the sequelae of tumors and/or treatment, and in changing prognostically unfavorable lifestyles (e.g., nicotine and alcohol consumption, little physical activity, a fat-rich diet, psychological stress). These are an adjunct to the active therapy elements in the sequential rehabilitation of physical function (e19). To these, in medical therapy for work-oriented rehabilitation for patients of working age, are added counseling using, for example, the diagnostic instrument AVEM (Arbeitsbezogenes Verhaltens- und Erlebensmuster, Work-Related Behavior and Perception Patterns), and a structured work-oriented training program (e20).
Instruments of occupational rehabilitation
In cases where cancer rehabilitation cannot entirely achieve the desired results, other measures promoting the return to work come into play. These measures may be listed as:
In 2010, 40% of all measures promoting a return to work were for the purpose of helping cancer survivors keep or get a job, while support for vocational training made up 22%. Six years earlier, the ratio was 24% to 30%, which shows that the DRV is increasingly following the goal of maintaining existing jobs using the instruments of occupational rehabilitation (e21).
Gradual reintegration
One long-established, successful instrument is gradual reintegration (stufenweise Wiedereingliederung, STW) (e22). The purpose of this is to take patients after long, serious illness and guide them gradually back to full-time work at their previous job and reintegrate them there.
In cancer rehabilitation, it is important to tell patients who still have a job, and who will on medical grounds be able to return to it within the foreseeable future, about the gradual reintegration program. Taking only these patients into account, a survey of insurees showed that a total of 86% of insurees opt for gradual reintegration when it is recommended to them. Careful selection of candidates for gradual reintegration usually reaches those patients who themselves express a desire for gradual reintegration.
In addition, the attitude of the employer plays an important part in the return to work. If the employer supports it, the probability of a successful return to work increases markedly. The main reasons given by patients for not taking up the offer of gradual reintegration include:
However, there are no data from controlled randomized studies.
Summary
On the basis of the current literature, it can be postulated that more than half of all patients with breast cancer in Germany return to work after their illness. This percentage is quite low in comparison to other countries. The most likely reason is that in Germany there is good financial support from the state for those who are unable to work.
Whether and to what extent a patient is able to return to work, and in what form, depend on many factors relating to both the disease and its treatment. Commitment on the part of the employer in making use of measures supporting the return to work, and the personal motivation of the patient as regards continuing to work, are also important.
Supporting measures to assist rehabilitation after cancer can be significant for the return to work. This assumption, however, is still unsupported by high-quality studies. Measures supporting a return to work, which should be initiated before the end of a cancer rehabilitation program, can also be useful elements promoting reintegration into working life. This is another point on which the evidence base is poor. In our opinion, therefore, the current rehabilitation measures available to promote the return to social and working life need to be more intensively evaluated, their effectiveness needs to be underpinned by prospective randomized studies, and further educative and psychosocial care leading on from cancer rehabilitation should be established.
