Enhanced provider communication and patient education regarding return to work in cancer survivors following curative treatment: a pilot study

BACKGROUND: For employed cancer survivors, returning to work and maintaining employment is an important aspect of their quality of life. We developed an intervention aimed at enhancing this by means of (a) providing the patient with an educational leaflet on return to work and (b) enhancing communication between attending and occupational physicians. The purpose of this study is to test the feasibility of this intervention and to examine the relation of patient adherence to the advice of the leaflet and return to work. METHODS: A patient series of 35 employed cancer survivors was used to evaluate the intervention. Survivors completed a baseline questionnaire prior to their treatment. Survivors and occupational physicians were interviewed by telephone eight weeks following all curative treatment. Our measure of feasibility included satisfaction of survivors with the intervention, adherence to the advice, time to return to work, satisfaction of occupational physicians with the intervention, and perceived influence on their rehabilitation efforts. RESULTS: Interviews of 26 survivors and 24 occupational physicians, revealed that those groups perceived the leaflet as useful (i.e., 7 on a 0-10 scale. Also seven out of ten suggestions in the leaflet was adhered to and half of the occupational physicians perceived the guidance they provided was helpful. However there was no effect of level of adherence on actual return to work. CONCLUSION: This pilot study demonstrated the feasibility of the approach used. However level of adherence to educational leaflet was not associated with an improvement in return to work in cancer survivor

Intraperitoneal Photodynamic Therapy: Comparison of Red and Green Light Distribution and Toxicity

The aim of this study was to compare red (652 nm) and green (514 nm) light for photodynamic therapy (PDT) of the peritoneal cavity with emphasis on light distribution and toxicity. Red-light PDT was limited by intestinal toxicity and it was hypothesized that less penetrating green light would allow higher light doses to be used in the peritoneal cavity. Female non-tumor-bearing rats were photo-sensitized with mTHPC (meta-tetrahydroxyphenylchlorin, Foscan®) intravenously or intraperitoneally and the peritoneum was illuminated using a minimally invasive technique. For both red and green light, the time of illumination was varied to give the required dose. Light fluence rate was measured in situ at multiple sites within the abdominal cavity. The toxicity experiments were carried out with a total of 160 J incident red or 640 J incident green light and a drug dose of 0.15 mg/kg Foscan®. For red light a mean fluence rate of 55.2 ± 38.5 mW cm -2 was measured, with a peak fluence rate of 128 mW cm-2 on the intestines. For green light the mean and peak fluence rates were 8.2 ± 9.0 (i.e. including zero fluence rate measurements) and 28 mW cm-2 respectively. Intestines were most vulnerable to red light illumination. The intravenous injection route resulted in increased toxicity for red light, but for green light there were no major differences between intravenous and intraperitoneal routes. The 4 h interval between drug and illumination resulted in very little toxicity for both wavelengths. We conclude that for intraperitoneal PDT green light allows higher light doses than red light, but the light distribution over the peritoneum is much less favorable and may not be suitable for whole peritoneal illumination using a minimal-access technique
