BACKGROUND: Breakthrough pain is transitory exacerbation of pain that occurs
in addition to otherwise stable persistent pain. The wide differences in
estimation of incidence reported in literature are probably because of different
settings and meanings attributed to the definition to breakthrough pain.
METHODS: A panel of experts met to establish the actual knowledge on
breakthrough pain, according to the evidence in literature and experience. They
agreed that episodic or transient pain could be a more simple and adequate term
in most languages, including English, France, Italian, and Spanish.
RESULTS: A specific assessment and precise pain characterization are essential to
plan the most appropriate treatments. Despite the relevance of this temporal
pain pattern for the influence on the outcome and quality of life, few controlled
studies have been performed to give evidence of a specific approach. Several
experiences have reported the possible efficacy of different drugs, route of
administration, and modalities of administration in different circumstances.
CONCLUSIONS: Prospective studies with previous treatments using similar
terminologies are necessary to find the most convenient therapeutic
intervention, according to the temporal pattern characteristics and the pain
mechanism involved.

Breakthrough pain… stories
Prima definizione:
“BTcP is a transitory increase in pain to greater than moderate intensity
which occurs on a baseline pain of moderate intensity or less
(Portenoy and Hagen, 1990).

?
Pain intensity should be severe (on a numerical scale 7/10), but the baseline
pain could be moderate (on a numerical scale 4-6/10) (Serlin et al., 1995). Thus,
the differences between the intensity of BTcP could be minimal (1-2 points on a
numerical scale).

Pts admitted in APRPC were divided in the following
classes, according to the level of background pain
intensity and analgesic drugs used at admission (T0):
a. Patients with no pain-mild pain NO opioids
b. Patients with mild pain receiving weak opioids
c. Patients with moderate pain receiving weak opioids
d. Patients with severe pain receiving weak opioids
e. Patients with mild pain receiving strong opioids
f. Patients with moderate pain receiving strong
opioids
g. Patients with severe pain receiving strong opioids
h. Patients with severe pain, receiving NO opioids
i. Patients with moderate pain, receiving NO opioids.
MEANINGFUL CUT-OFF PAIN INTENSITY FOR BTcP
CHANGES IN ADVANCED CANCER PATIENTS. Submitted
The meaningful pain intensity for asking for a BTcP
medication was 7.1/10. 77% of patients had a pain
intensity of 7-8 on a numerical scale 0-10.
The meaningful pain intensity for adequate analgesia
after a BTcP medication was 3.5/10. Similarly, 77% of
patients had a pain intensity of 3-4.
There was no relationship with the variables examined
for coping. Concerns about the use of BTcP medications
were minimal.
Dolore osseo: prognosi

Per la sua natura intermittente, il dolore è difficile da
controllare, e limita il malato ad evitare di muovere con
ovvie conseguenze sulla qualità di vita.
Il dolore incidente associato a metastasi ossee è
considerato un fattore prognostico negativo per il
controllo del dolore (Bruera et al,1989, Mercadante et
al,1992).
 La libertà di movimento è particolarmente difficile da
raggiungere (Banning et al,1991).

Short-acting opioids are the mainstay
of pharmacological treatment1
Due to its nature, breakthrough cancer pain requires a treatment that:
Has a fast onset of action2
Is appropriate in its potency3
Is easily administered3
The WHO analgesic ladder recommends background pain is controlled
with around-the-clock analgesia4
Issues with opioids:1
Only effective if breakthrough cancer pain is an opioid-responsive
pain1
Only effective if onset of action reflects the duration of the episode1

La necessità di ricorrere ad ulteriori dosi è stata maggiore nel
gruppo T per il primo episodio (P< 0.0005). In pazienti che
ricevevano dosi di morfina >120 mg/die, un numero
significativo di pazienti ottenne una riduzione del dolore

Conclusione
Il BTcP di tipo incidente al movimento richiede un’ accurata
valutazione sulle caratteristiche temporali di latenza e durata e
persistenza dello stimolo, che si presentano in maniera molto
diversa.
 Particolare attenzione dovrà essere posta sulle possibilità di
trattamento delle metastasi ossee
 Dovranno essere considerati anche obiettivi realistici rispetto alle
capacità di movimento ed alla prognosi.



In base a tali caratteristiche si sceglierà il potenziamento dell’
analgesia di base con i mezzi farmacologici disponibili, e il farmaco
al bisogno da utilizzare.
Considerata l’ eterogeneità del BTcP, si dovrà personalizzare il
trattamento
Breakthrough pain in elderly
 No studies performed with the primary
outcome of comparing adults and old
patients.
Experience provide infomation that that
opioid tolerant patients can be treated with
proportional doses safely.
 Perception of less tendency to call for
BTcP events
 Studies ongoing
