Introduction objectives: Breakthrough cancer pain (BTcP) is an acute exacerbation of baseline pain. The clinicians involved in its management have different diagnostic and therapeutic criteria.In order to facilitate decision making in usual clinical practice, 8 reference experts from 4 scientific associations involved in the management of patients with cancer pain have developed this Consensus Document.Methods: After an initial search on the most relevant publications in BTcP literature, a set of preliminary recommendations were established. A working meeting was subsequently held with the experts, following the Metaplan® methodology -a structured brainstorming technique-that produced a first version of the Consensus Document which, after several review rounds, was validated by all the participants. Every statement and recommendation was sorted according to its degree of recommendation, following the categories in the SIGN (Scottish Intercollegiate Guidelines Network) system.Outcomes: The management of BTcP requires a full anamnesis, both of BTcP itself and of baseline pain, a physical examination and the supplementary tests that are deemed necessary.The drugs of choice for the treatment of BTcP must be those with a potent and rapid analgesic effect a short duration, minimal side effects and easy administration. Transmucosal fentanyl is currently the active ingredient most fitting to the analgesic needs of BTcP, regardless of the major opioid used for control of the baseline pain.Conclusion: This Consensus can be a very useful tool to improve the quality of life in cancer patients, because it guides the clinician towards a better diagnose and treatment of BTcP.
This randomized pilot study was designed to determine whether the addition of interferon alpha-2b to standard radiation therapy offered an advantage in loco-regional control and survival over radiation therapy alone in a homogeneous group of patients with stage IIIB carcinoma of the cervix. Thirty-six patients were treated with a combination of interferon alpha-2b plus radiation therapy, and 38 patients were treated with radiation therapy alone. Patients with evidence of ureteral obstruction were excluded from the study. Evaluation of loco-regional response was determined by pelvic examination, cervical cytology, biopsies and CT scans when indicated. Survival time was measured from initiation of treatment to date of death or last follow-up. Patient characteristics were comparable between both study arms. The objective complete response rate was 67% in the combined therapy group and 55% in the radiation alone group (P = 0.454). With a median follow-up of 17 months for all patients and 31 months for live patients, 50% of the combined group survived vs. 39.5% of the radiation alone group (P = 0.424). We conclude that the addition of interferon alpha-2b to standard radiation therapy did not significantly improve loco-regional response or survival, although such a trend was noted. We encourage the design of a larger randomized study with sufficient power to detect meaningful differences to prove whether the tendency observed in the present investigation holds any promise to improve the outcome of these patients.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
