Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVE:
I. Determine the feasibility of using humidified phytoncides to simulate the forest greenspace immersion (simulated forest immersion therapy [SFIT]) in cancer patients with solid tumor who have completed surgery, chemo- and radiation therapy as an alternate method of access to the natural forest greenspace.
SECONDARY OBJECTIVE:
I. Determine the feasibility of collecting and analyzing immune system measures while deploying the simulated forest immersion therapy with forest oils (SFIT), as well as measuring natural killer (NK) cell number and activity, and perforin and granulysin.
OUTLINE:
Patients participate in SFIT, using humidified wood and fragrance oils, over 1 hour. Patients also undergo blood sample collection at baseline and on day 3 or 4 and participate in interviews at baseline and post-treatment.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Age >= 18 years. Both men and women and members of all races and ethnic groups will be included
- Participants must have histologically or cytologically confirmed hormone receptor positive (HR+) HER2 negative (-) breast cancer or prostate cancer (hormone therapy excepted) who are in Stage I-III with or without evidence of metastasis using the Cancer Therapy Evaluation Program (CTEP) Simplified Disease Classification
- Participants must be within 12 months of their first diagnosis of breast or prostate cancer
- Criteria for solid tumors: Participants must have measurable disease, per MD and data in medical record
- Participants must have no history of autoimmune disease
- Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria:
- If they have asthma. Rationale: forest oils may be a possible trigger for asthma)
- If they have a known allergy to citrus peel or pine forests. Rationale: forest oils may cause contact dermatitis and coughing
- If they are unable to detect common odors from commercial fragrances. Rationale, forest oils are humidified as an aroma to be inhaled in the simulate the forest greenspace immersion (SFIT)
- First diagnosis of breast or prostate cancer is longer than 12 months ago. Rationale, NK cell number recovery may be complete by this time after first treatment
- Febrile illness/infection within previous two weeks. Rationale, immune biomarkers will reflect previous febrile illness
- Current tobacco or tobacco use within 1 hour of start of SFIT. Rationale: forest oils may cause contact dermatitis and coughing
- Prior autoimmune disease, are on immune-modulating therapies (endocrine therapy allowed). Rationale, because of their poor prognosis rather than being in early stages of cancer
- Had surgery or invasive procedure in the past two months. Rationale, because of their poor prognosis rather than being in early stages of cancer
- Inability to complete study requisites

Intervention / Treatment |
---|---|
Experimental: Supportive care (SFIT, biospecimen, interview)
Patients participate in SFIT, using humidified wood and fragrance oils, over 1 hour.
Patients also undergo blood sample collection at baseline and on day 3 or 4 and participate in interviews at baseline and post-treatment.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Humidified phytoncides to simulate the forest greenspace immersion (SFIT)
Time Frame: Baseline/Day 1
|
Feasibility analysis will include qualitative interview data blinded by participant, CRC/research assistant and principal investigator.
Qualitative interview questions include ease of use/deployment of humidified forest oils by the CRC/research assistant and PI, the ability of the participants to tolerate SFIT.
The responses will be coded, themed and summarized will be used to determine the feasibility of intervention deployment and creation of a standardized procedure for future research.
To determine dose drop off between the start of SFIT and the end of SFIT of the humidified phytoncides a t-test with an alpha level of 0.05 will be used.

Baseline/Day 1

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Collecting and analyzing immune system measures while deploying the simulated forest immersion therapy with forest oils
Time Frame: Baseline and at day 3 or 4
|
Will measure natural killer (NK) cell number and activity, and perforin and granulysin.
NK cell number (NK CD3-/CD56+/) and activity (NK CD3-/CD56+/CD69+) will be tested with Flow Cytology.
Perforin and granulysin will be tested by ELISA.
Will use a t-test to determine the differences between these 4 variables collected at baseline and a Day 3-4.
An alpha level of 0.05 will be set.
Alternate analysis, the change NK cell number and activity will be determined from the mean of the standard range.
