With
“rapid transit”
a major everyday problem, her GP prescribed Codeine
Phosphate, utilising its constipating side effect.
This relatively
simple action fairly early in now in 1995, made a tremendous difference
on its own, for which she
was very
grateful. If an attack is indicated, she stops the Codeine Phosphate
until the
blockage has passed, then recommences when confident it is safe to
do so.
However, attacks of pain and vomiting were increasingly frequent by the later 1990's. So she felt that every avenue had to be explored, and with surgery ruled out, felt the time had come to draw a line under it and concentrate on management of the condition. She continues to see her consultant oncologist who treated her initially, and who has been so willing to suggest and prescribe medication to help manage the attacks and refer on as necessary. Dextromoramide was used for severe pain. Unfortunately this became unavailable, so Buprenorphine sublingual (Temgesic) was tried in Oct 2005. Buphenorphine is easy to take as it dissolves under the tongue, so no need for water when vomiting is likely or going on. But it was not nearly as good as Dextromoramide. In 2001 Janice was referred, by her oncologist, to a gastroenterologist with a special interest in fibrosis resulting from radiotherapy. He carried out a series of tests and scans initially, so he knew exactly what he was dealing with. His suggestions included some interesting ideas, such as Hyperbaric Oxygen Treatment (HBO). Both HBO and a drug called Pentoxifylline help to reduce fibrosis and HBO for difficult to heal wounds. (see HBO page for more on HBO). He was very keen for Janice to try these, but starting with antibiotics. If this was unsuccessful, Pentoxifylline, which is designed to improve blood flow to damaged areas and licensed for peripheral vascular disease and venous ulceration would be tried. She did not opt for the Hyperbaric Oxygen Treatment for various reasons. |

This
therapy consists of having
regular and repeated sessions breathing 100% oxygen in a recompression
chamber
at higher than atmospheric pressure. HBO is thought to be helpful for
radiation injuries to soft
tissue
and bone.

Codiene Phosphate
has been mentioned already and is very effective at slowing
"rapid
transit". It is purely for symptomatic relief and does nothing to
reverse the damage of course.
Pentoxifylline (PTX) and alpha-tocopherol (vit-E) is different (see next section). It has been trialled and used in various centres. The links below give some more information on this regime. Institute of Cancer Research & Royal Marsden Hospital :- This link to the Department of Health Register shows the Royal Marsden has been undertaking a double blind, placebo controlled, randomised drug trial for bowel symptoms after radiotherapy to end in December 2006. Janice was not able to take part in an earlier trial, but was permitted the drug regime (Pentoxifylline and Alpha-Tocopherol), so at least she knew it was not the placebo. The following also reports from New York on the same drug regime for Radiotherapy Induced Uterine Damage. A link to endometriosis, an inflammatory condition, also reports the use of Pentoxifylline [Trental] for this condition and mentions its use for fibrosis and chronic scarring from “a number of diseases”.

radiotherapy
damage in a clinical trial using PTX and vit-E
from a source in Paris
in 1999.

As
the antibiotic treatment was
ineffective, Janice started PTX + vit-E in February
2002. This had been shown to have a reversing effect on fibrosis
following
radiotherapy for breast cancer according to trials carried out by the
Royal
Marsden Hospital and others, though the effect on the bowel was unknown
at this time.
Initially it appeared to have no effect on Janice, indeed she was
hospitalised
with a series of attacks in July 2002 requiring rehydration, morphine
and a gastric nasal tube.
Undeterred, she continued with PTX + vit-E, as she had been advised that the process of fibrosis reversal, if it was going to work at all, would be very slow. Until recently it had been thought that fibrosis was irreversible, but this not the case, as these drug trials, and other therapies such as hyperbaric oxygen have indicated. Janice had been free of these major attacks since July 2002, but unfortunately, Christmas 2002 was ruined by a prolonged attack, though not hospitalised. Optimism remained, however, as the attacks had formerly been so frequent, so maybe the drugs were having the intended effect. There seemed to be no other reason for it. See Update page for times since 2002. |

| It
is very important that people suspected of having radiation damage,
with substantial problems such as faecal or urinary
leakage, bowel
blockages that occur regularly, bleeding, inability to retain weight,
or anything unusual,
should be
referred to a specialist who has a special interest in radiotherapy
injuries. For damage to the bowel as a result of radiotherapy to the
pelvic area, this will
usually be a gastroenterologist, but does need to be someone with a
specialist interest in radiation diseases. If the problems are
principally
bone related such as osteoradionecrosis then perhaps a different
specialist is appropriate. The more that people come forward with these problems, rather than suffer in silence, the more seriously this will be taken by GP's and other cancer specialists allowing more resources to be directed at the problem. Presently there are few doctors, even worldwide, dedicated to this specialty. A small but informative article on how gastrointestinal symptoms are diagnosed and treated, is published from the Royal Marsden here |
