Breakthrough cancer pain is defined as transient pain exacerbation in patients with stable and controlled basal pain. Although variable, the prevalence of breakthrough cancer pain is high (33%–95%). According to the American Pain Foundation, breakthrough pain is observed in 50%–90% of all hospitalized cancer patients, in 89% of all patients admitted to homes for the elderly and terminal-patient care centers, and in 35% of all ambulatory care cancer patients. The management of breakthrough cancer pain should involve an interdisciplinary and multimodal approach. The introduction of new fentanyl formulations has represented a great advance and has notably improved treatment. Among these, the pectin-based intranasal formulation adjusts very well to the profile of breakthrough pain attacks, is effective, has a good toxicity profile, and allows for convenient dosing – affording rapid and effective analgesia with the added advantage of being easily administered by caregivers when patients are unable to collaborate.
Breakthrough cancer pain (BCP) is common in patients with cancer, causing a negative impairment in quality of life. Recent diagnostic criteria allow for differentiation of background chronic pain and BCP, for which proportion of unpredictable episodes is very high. Five characteristics define BCP: rapid onset, high intensity, maximum intensity (minutes), mean duration 30 min, and unpredictable onset. Fentanyl is a synthetic opioid characterized by rapid absorption and start of the analgesic effects. In addition to comparing some of the marked differences between the four pharmaceutical forms of fentanyl marketed in Spain, this paper discusses the data collected in a comprehensive clinical trial program with fentanyl pectin nasal spray (FPNS), a formulation that takes advantage of the intranasal route and the PecSys™ technology. The FPNS formulation achieves analgesic action 5 min after application and significant pain relief at 10 min. FPNS, therefore, has key features to be an optimal treatment for BCP.
ObjectivesPatients with cancer are at higher risk for severe COVID-19 infection. COVID-19 surveillance of workers in oncological centres is crucial to assess infection burden and prevent transmission. We estimate the SARS-CoV-2 seroprevalence among healthcare workers (HCWs) of a comprehensive cancer centre in Catalonia, Spain, and analyse its association with sociodemographic characteristics, exposure factors and behaviours.DesignCross-sectional study (21 May 2020–26 June 2020).SettingA comprehensive cancer centre (Institut Català d’Oncologia) in Catalonia, Spain.ParticipantsAll HCWs (N=1969) were invited to complete an online self-administered epidemiological survey and provide a blood sample for SARS-CoV-2 antibodies detection.Primary outcome measurePrevalence (%) and 95% CIs of seropositivity together with adjusted prevalence ratios (aPR) and 95% CI were estimated.ResultsA total of 1266 HCWs filled the survey (participation rate: 64.0%) and 1238 underwent serological testing (97.8%). The median age was 43.7 years (p25–p75: 34.8–51.0 years), 76.0% were female, 52.0% were nursing or medical staff and 79.0% worked on-site during the pandemic period. SARS-CoV-2 seroprevalence was 8.9% (95% CI 7.44% to 10.63%), with no differences by age and sex. No significant differences in terms of seroprevalence were observed between onsite workers and teleworkers. Seropositivity was associated with living with a person with COVID-19 (aPR 3.86, 95% CI 2.49 to 5.98). Among on-site workers, seropositive participants were twofold more likely to be nursing or medical staff. Nursing and medical staff working in a COVID-19 area showed a higher seroprevalence than other staff (aPR 2.45, 95% CI 1.08 to 5.52).ConclusionsAt the end of the first wave of the pandemic in Spain, SARS-CoV-2 seroprevalence among Institut Català d’Oncologia HCW was lower than the reported in other Spanish hospitals. The main risk factors were sharing household with infected people and contact with COVID-19 patients and colleagues. Strengthening preventive measures and health education among HCW is fundamental.
