Do Cancer Survivors Live Longer When In A Long-Term-Care Facility? -Possibility of Harmless Cancer In Oldest Old
We had an infant patient with advanced neuroblastoma who was reported by several pediatric surgeons with spontaneous remission . We also had a patient with advanced gastric cancer who underwent“Laughter therapy”inducing radical remission . There are many reports on cancer patients from the medical provider side, however, there are few reports available from long-term-care facilities. This report addressed oldest old cancer survivors from the perspective of long- termcare facilities. Furthermore, I had reported our experience on harmless cancer and advanced cancer that did not manifest any symptoms .
In April 2015, an analysis of cancer survivors of oldest old was carried out at Seiwaen, a long-term-care facility for the elderly. This facility is where the elderly or “guests” resided after discharge from a semi-acute care hospital. In the said facility, a routine laughter therapy was implemented with the guests who were already in various levels of dementia.
Cancer survivors who had dementia did not feel stress as much as the ordinary cancer survivors did. The guests without dementia, including cancer survivors, took not only routine laughter therapy, as well as study class with laughter. Thereafter, an exploratory research was carried out, and the effect of dementia and laughter in cancer survivors of the aged was evaluated.
In general, a patient with cancer had a poor prognosis, and the number of elderly cancer survivors was considered to be smaller in number among all age groups. However, our guests with cancer were oldest old and were living happily. By analyzing the “cancer survivors of oldest old”, we would like to explain the following two issues:
1. Why cancer survivors in an elderly facility showed asymptomatic?
2. Does the new“harmless cancer” hypothesis which can give explanations to these case examples, provide a stress-free state, dementia and laughter?
How should a malignant tumor be dealt with in an aging society?
We believe researches on tumor activities in relation to age and emotional status should be studied in cancer research. In order to contribute to its small basic data, we decided to write a manuscript for publication in the Jacobs Journal of Cancer Science and Research
The authors have obtained full informed consent from subjects and/or legal representatives of this study and got the approval from an ethical committee at Seiwakai Foundation.
The average age of the guests in Seiwaen was 86.3 years. As of April 2015, there were 15 resident subjects with a history of cancer at Seiwaen. One rectal cancer survivor with lung metastasis was counted as a single cancer. Several cases of multiple primary cancers were seen (Table 1).
All the residents in Seiwaen, ranked by dementia severity using the Hasegawa Dementia Scale (HDS) from 0 (complete dementia) to 30 (normal), were studied. HDS, a simple intelligence test, was often used along with the MMSE in Japan . The cutoff value was 20/21. There were two wards in the facility: one dementia ward for guests with under 11 points of HDS (mean
5.5 points) and one general ward for the guests with above 12 points of HDS (mean 22.3).
The guests were treated as well-beings not as patients. The guests were stimulated through laughter by praise and by experiencing fun during rehabilitation and recreation, either individually or as a group. The smile-sun method (SSM), were procedures used by well-trained staff to enhance interpersonal skills, as well as to produce affective change .
In the general ward, daily study sessions for participants and staff were actively held, including “Laughter therapy”. A wide range of a combination of medical matters and sociological issues were discussed with laughter. The sessions concluded with everyone in a positive mood. Even guests with behavioral and psychological symptoms of dementia (BPSD), i.e. schizophrenia or dementia with Lewy Bodies did not show disturbing behavior due to the warm care being provided and mild antipsychotics. Cancer survivors at Seiwaen were analyzed according to the relationship between dementia and laughter.
SPSS version 11 was used for the statistics analysis.

Epidemics and dementia
Fifteen out of the 90 patients (16.7%) were cancer survivors, and six had multiple primary cancers. Average ages were, 86.3years, 87.6 (SD9.0) years old with 11.00 (SD10.8) survival years, and 91.6 (SD6.0) with 15.7 (SD10.1) survival years, respectively. The average age of cancer survivors was high and that of multiple primary cancer survivors was higher(p < 0.05)compared to all the guests. The age diagnosed as a cancer was 77.3(SD12.8) years old and cancer history was 10.3 (SD11.5) years. The cancer survivors, one third of whom were with multiple primary cancers, lived longer and without any complaint symptom. The Hasegawa Dementia Scale showed 13.7(SD10.5) in cancer survivors. Seven cancer survivors (average HDS:4.7) were in the dementia ward while eight survivors (average HDS:20) were in the general ward. Six survivors with multiple primary cancers had more severe dementia than the single cancer survivors(t(20)=6.333, p<0.01). Six cases were not treated because the guests, themselves, or their families re-fused treatment due to severe dementia or age of the guests at the time of diagnosis. There is a significant difference in the number of years that had elapsed between treated and untreated survivors (t(15.133)=4.336, p<0.01). Since the onset of the disease was in the older, the untreated survivors had shorter survival years compared with the treated survivors(t(20) = 2.972, p<0.01).
Behavior and symptoms
Guests with reported resistance to nursing care or refusal to feed in the previous hospitals changed their outlook and behaviorafter staying in our facility.
By treatment as a well-being and by watching behavior of similar disability guests, they lived contentedly and confidently.Routine health check for all guests revealed no abnormal results except for changes in the age-appropriate.
An 85yo female guest with malignant lymphoma of stomach with severe anemia during admission improved to normal without any treatment. A 96yo male with rectal cancer with lung metastasis refused surgery even after several episodes of bloody stool. However, his anemia improved by eating well in the facility and living happily and enjoying music, i.e. singing songs. Currently all survivors live happily and without symptoms.
Multiple primary cancers
Six out of seven survivors in the dementia ward had multiple primary cancers (Table 2). The age of the first cancer diagnosedwas similar to those with single cancer and they had a second cancer after five years, although the expression time ofdementia is unknown.
Table 2. Comparison of cancer survivors in wards, number of cancers, and age at onset(diagnosed).
Effect of “Laughter Therapy”
Most guests in the general ward joined the study session of Laughter Therapy voluntarily. They changed to a cheerful characterwith laughter.
Survivors with/without dementia never complained of anxiety and worry of cancer. Unpaired t-tests were done from the onsetand according to age in both wards.
Age: t(13)=1.715, p>0.11 and survival years : t(13)=1.105, p>0.289.
One-way analysis about age and survival years proved no significant difference between both wards. We would like to suggestthe possibility that there is the same stress-free effect in the general ward, where laughter therapy is going on as in thedementia ward.
In general, patients with cancer had poor prognosis. In this series, cancer survivors did remarkably well, including survivorswith multiple primary cancers. This article highlights the importance of clinical evidence for further basic research as a role of tumor biology.
Why do cancer survivors live longer than the average life?
There were two possibilities: those who are in the advanced stage had already expired. It is well known that the later the onset of age of cancer, the lower the malignancy grade . Furthermore, there are three more issues to be discussed.
(1) There was some possibility that all survivors had early stage cancer cured before admission to our facility. Three-year-survival time for lung cancer in the elderly was considered as cured, such as our three survivors .
(2) There is a trend of reduction surgery or non-invasive anti- cancer agents for the elderly under the Japanese Cancer Society.Oncologists are less likely to offer trial participation to older patients . These procedures worked to preserve the physical fitness of survivors.
(3) Three out of six untreated cases had only CT diagnosis without biopsy.
It meant the possibility of insured diagnosis.
Characteristics of the elderly or disease
(1) There was the possibility of histologically slow progress cancer.
(2) The elderly survives easily to coexist with cancer. Previously, we reported four untreated cancer survivors . One of them was asymptomatic and expired by stroke, despite 90% of her liver growing cancerous. We call this a “harmless” cancer.
(3) Accompanying disease may seem asymptomatic, such as,complete paralysis due to Guillan-Ballet syndrome.
The association between diagnostic intervals and cancer survival was complex . Although we should take into account tumor biology and clinical practice, unnecessary reminder of the disease caused patient anxiety. Caregivers and healthcare providers had treated guests with fun and inactive follow-up patients with non-alert symptoms in the facility.
(1) Stress-free by dementia
Stress-free status in dementia may work for epigenetic factor to prevent progress of cancer, even for those with multiple primary cancers.
(2) Laughter and well-being might enhance epigenetic change
The smile-sun method (SSM) was used effectively . Well-being using “laughter therapy” may induce epigenetic change[10,11]. Laughter reduced stress . It was well known that immunity increases with laughter [13-15]. A recovery of post-stroke depression was reported in an acute care hospital where the entire staff had the laughter education . We had seven cases who had both paralysis and cancer. Survivors without dementia could have stress-free status by “laughter therapy” as those with dementia. The survivors in the dementia wards were older than survivors in the general ward. The difference of survival years between the two wards were less than one year and younger survivors in the general ward may survive longer in the future, as long as they did not show any major symptoms.
Description of new hypothesis
(1) Harmless cancer: Oldest old cancer survivors did not show any symptoms although the disease itself may progress. Sixuntreated cancer survivors had few symptoms and may possibly be categorized as harmless cancer.
(2) Dementia resulted in a completely stress-free status.
(3) Laughter therapy”may enhance free from stress.
Effect of psychotherapeutic support for cancer survivors have been reported [17,18]. There was a relationship between psychological work and duration of cancer survival [19,20].
Turner KA classified cancer remission into spontaneous remission and radical remission . A person who had a strongtendency to control life events by themselves and tried to live independently, had a strong tendency to achieve a radicalremission. Although most of our survivors were informed of their own cancers at some point in their life and were not shielded from heartbreaking ordinary life events, they all had bright personalities and were living happily without any problems at the facility. There is a possibility that the daily study sessions works as a psychotherapy.
Laughter therapy may have provided the positive attitude that contributed towards the survivors’ ability to keep themselvesfrom being adversely affected by cancer symptoms . Stressfree status by dementia or by “Laughter therapy” made the status of cancer harmless.
The exploratory research in the study could not explain scientifically the phenomenon that cancer-bearing patients live longer. A new idea of epigenetics is that the environment can change the expression of the gene. Having a positive mind allowedpeople to live happily . Stress-free with/without dementia and a positive mind by laughter therapy might be the key to epigenetic change.
Laughter had been proven to be effective enough to resemble an analgesic .
The effect of laughter might lead to spontaneous remission [15,20].
This study suffers from a very limited sample size and the number of patients is too small to make a conclusion. However,based on these clinical evidence, further research of larger cohort would greatly appreciated. A natural prevention mechanismof cancer cell growth involving immunological response related to psychological effect may serve to prolong life. The successful therapeutic applicability of this method depends on further research.
We would like to express our sincere appreciation to the staff of Seiwakai for their cooperation and warm reception, to Professor Hiroshi Matsuoka for his interest and full support by providing important information on statistics.
