When we are talking about breaking bad news, we need to consider these factors: 1.What percentage of cancer patients know their diagnosis and what is the source of information? 2. What percentage of cancer patients preferred to know and what was their preferred source? 3. What percentage of oncologists tries to disclose the diagnosis and what is their preference? 4. What is the impact of diagnosis disclosure on patients?
Regarding the first question, it seems that, in several countries, physicians approaches are more towards breaking bad news to their patients, due to an increased emphasis on respecting patients’ rights and sense of autonomy, while in several other countries, physicians hesitate to inform their patients about the diagnosis of cancer (
1,
16-
18). In our study, we found that 60.3% of patients under different types of cancer treatment, in designated hospitals, were aware of the diagnosis, while, depending on the culture, this percentile could be different in various countries (
18,
19). For instance, a study conducted in Thailand showed 63.2% of patients under radiotherapy treatment knew about their disease diagnosis, which is a close percentile to our results in Tehran, Iran. Overall, patients’ awareness of cancer varied from 38% to 98%, in various countries (
16). For example, a study performed in Taiwan, in 1996, indicated that only 37.2% of patients were informed of their diagnosis (
20). Another study, undertaken on 96 patients, in 2006 in Nepal, showed that 20% were informed about both diagnosis and prognosis of their disease, while only 17% only knew the diagnosis and 63% were not aware of their disease (
13). Also, in Portugal, 68.9% of patients were told about their cancer diagnosis (
17). In a study conducted in Riyadh, Saudi Arabia, Bedikian et al. found that only 16% of patients were told they have “cancer” and 34% were told to have “tumors” (
21). A research done in Tehran Cancer Institute, Tehran, Iran, on gastrointestinal cancer patients under treatment, showed that 52% knew the diagnosis (
22).
Cancer treatments, such as radiotherapy and chemotherapy, require patients to be informed of the procedures and continuous follow-up sessions to be continued. Therefore, it was expected to have more patients aware of their diagnosis. In this study, the necessary information regarding treatments was given to 92% of patients, unaware of their diagnosis, without mentioning the word “cancer”. According to a study conducted by Rodriguez et al. many physicians employ implicit language when discussing cancer diagnosis and prognosis with patients (
23).
In this study, only 60.7% of patients aware of diagnosis were informed by their physicians and other patients found out by other means, such as family members or hospital staff. Another descriptive study in Iran indicated that 66% of cancer patients were informed about the diagnosis by their physicians, while others got the news from relatives. According to this research, cancer patient education, prior to treatment, was poor in Iran (
6). In our study 65.6% (57.8% + 7.8%) of informed patients stated that their physician gave them related information. Therefore, based on these two studies, on Iranian cancer patients, there is still a group of Iranian physicians who refuse to provide information regarding malignancy for their patients.
What percentage of cancer patients prefer to know and how much and which is their preferred source? In our study, we found that 92% of patients, with whom the diagnosis was discussed, preferred to know the diagnosis and 88% hoped to be given more information about their disease by physicians. Most patients (73.7%) would rather hear the bad news from their own physician (see
Table 5). Based on these results, it seems that most Iranian cancer patients would rather know the diagnosis of cancer. Moreover, it seems patients’ preference in Iran differs from what doctors might think about patients’ preference and their psychological reaction, following the disclosure. These results are close to what researchers have found in Iran and other countries. In a study conducted on 167 Iranian cancer patients and 143 family members, 97% stated they would like to have more information on cancer and possible treatments (
22). In a study conducted in Portugal, 74% of patients wished to know everything regarding their disease, in detail, and 85% preferred to be informed about the diagnosis, in case they had cancer. Also, 95% stated they would want to be told the best and worst circumstances of their disease and 92.7% wanted their physician to disclose the diagnosis (
17). Similarly, in a country with a completely different culture, such as Nepal, 80% of the general population preferred to be informed about their disease in, case of having cancer (13). Moreover, even among the terminally ill, as well as poor prognosis cancer patients, it was found that they significantly preferred disclosure (directly by a physician) and they preferred to choose palliative care options (
24).
What percentage of oncologists tries to disclose the diagnosis and what is their preference? Physicians’ preference on diagnostic disclosure and providing necessary information to patients has been found to be different, in various countries. In Northern Europe and America, most doctors prefer to disclose diagnosis and this approach is seen mostly during the past three decades (
19). Nonetheless, in several countries, physicians still do not follow this approach. In a survey done in 1987 on oncologists in Iran, Hungary, Panama, Portugal, France, Spain and African countries, only 40% would discuss the diagnosis with their patients and most physicians prefer to tell the diagnosis of malignancy to patients’ families (
25). In another survey done in 1998 in Japan, 40% of physicians reported to disclose diagnosis with patients, which had an uprising trend compared with several previous decades. However, this percentage is still much lower than United States and Northern European countries (
26). In a study conducted in 1998, in Lebanon, 47% of physicians were found to discuss patients’ diagnosis with them (
27).
Regarding the fact that there was a small percentage of patients, in our study, who did not wish to know the diagnosis, it seems necessary that, prior to having the precise results, physicians ask patients about their preferred method for discussing the diagnosis and to what extent they would like to know the diagnosis and its prognosis. This is one of the main principles of most proposed methods for breaking bad news (
28,
29). In other words, individualization or tailoring communication, according to each patient’s own personality characteristics, as well as his/her coping style, is necessary.
What is the impact of diagnosis disclosure on patients? Most physicians refuse to give bad news, to avoid psychological damage to their patients (
22). However, several studies indicated otherwise. A study performed in Japan, by Horikawa et al. on patients who were not aware of diagnosis and referred to psychiatrics, indicated a higher level of anxiety, irritability and suicidal ideations (
30). According to a research conducted by Hosaka et al. the occurrence of psychiatric disorders, found in patients aware of diagnosis, was not much different (42.9%) than in those who were not informed (48.3%) (
31). In a study from 2010, Jackson et al. showed that, following diagnostic disclosure, patients with prostate cancer had higher motivation for finding social support resources, which both ultimately led to an increase in positive emotions (
32). In addition, Lin et al. reported that Taiwanese patients, who were aware of their cancer, were more satisfied of their therapy sessions and pain control and had better quality of life (
33). Based on these results, it seems that hiding information from patients will not psychologically help them.
In this research, psychiatric assessment was not performed on patients and only subjective sense of suffering, reported by patients, was studied. The results indicate that, in 81.6% of cases reported, they had felt nervous, anxious and depressed, following being informed about their diagnosis. However, 57.9% reported that they could finally adjust with the new situation and seek help and treatment. In addition, 78.9% of patients mentioned that they would have been in bad psychological mental state, if they had not known about their diagnosis. However, following the diagnostic disclosure, 15.8% of patients were still found worried and preoccupied about their condition, at the time of interview, and 26.3% reported psychiatric symptoms, such as anxiety and depression. The prevalence of depression, anxiety and other psychiatric morbidity is found to be high among cancer patients (
34,
35). This is also the case in Iran and, in a research conducted by means of Hospital Anxiety and Depression Scale on gastrointestinal cancer patients, 47.2% reported high score for anxiety and 57% for depression. The scores were higher among patients who knew their diagnosis (
36).
In this study, we found that several patients are not able to cope with their illness, following the disclosure, and several require psychological and psychiatric support. For instance, participation in group therapy can reduce patients’ anxiety level to a great extent (
37). Therefore, it is important to monitor patients’ mental state, during specific cancer treatments and, if necessary, provide them with psychiatric help. On the other hand, we found that 68% of patients, who were not told the diagnosis, were still preoccupied by their disease and stated that they were in different emotional state, compared to the time prior to sickness. Also, 88% of these patients preferred to be informed about their disease by physicians. These results not only show that withholding cancer diagnosis, by physicians, does not necessarily decrease patients’ stress and anxiety, whereas most of them stated to be still under stress (
31). In any case, when it comes to disclose a terminal illness, patients should be psychologically prepared to hear about it. Otherwise, their psychological discomfort would be at high and intolerable level. This research suggests that it may be better to train physicians with proper communication and disclosure skills. Education about how to give bad news is not common in Iran and Middle Eastern countries (
18). Moreover, the other common problem is the lack of professional codes, as well as legislations, regarding the patients' rights in an informed consent (
18). Current legal norms, towards cancer disclosure, are also vague, even in several developed far eastern countries (
38). Considering rules and legislations about patients’ autonomy and providing training programs for physicians are needed in our society.
In this study, we were unable to employ cancer patients from total population; instead, patients were chosen from those under radiotherapy or chemotherapy treatment, in university hospitals. Tendency in knowing the diagnosis may be higher in patients under treatment (
16). Also, this study was conducted on patients with cancer, and, therefore, it may not be true for overall healthy population. The rate of preference for diagnostic disclosure, among Iranian patients in early stage of cancer, is unknown and could be the subject of future studies. To find out if Iranian healthy individuals would still prefer to know the diagnosis, if faced with cancer, more surveys among general population will be required. In addition, patients living in the capital city, Tehran, may differ in preference from those from other cities; however, 44% of our patients were living in cities other than the capital. We proposed further investigations in other cities and different cultural backgrounds. Moreover, our patients vary in type of cancer and its stage and we did not consider staging of cancer, as an important variable. It is found that the type of cancer and cancer stage could affect patients’ preference in knowing the diagnosis, as well as physicians approach to disclosure (
16,
19). Comparing attitudes toward disclosure, as well as psychological reactions, among different types of cancer, could be investigated in the future studies.
The results of this study indicated that Iranian patients undergoing radiotherapy or/and chemotherapy, like patients in most countries, prefer to be informed about their disease. Most of them would like their physicians to perform the diagnostic disclosure. However, despite this preference, several patients receiving therapy may never know the diagnosis. This shows that certain Iranian physicians would not like to give bad news directly to their patients. It seems that diagnostic disclosure may result in more pain and suffering, for a short period of time. Nevertheless, more patients prefer to know the diagnosis, despite their stress. Regarding patients who were aware of diagnosis, several of them can adapt themselves with the new condition. However, others may need psychiatric evaluation and psychological assistance.
