Procedural pain in patients with cancer: a Delphi expert management consensus

OBJECTIVES

Diagnosis, treatment and care of cancer often involve procedures that may be distressing and potentially painful for patients. The PROCEDIO Study aimed to generate expert-based recommendations on the management of moderate to severe procedural pain in inpatients and outpatients with cancer.

METHODS

Using a two-round Delphi method, experts from pain and palliative care units, medical and radiation oncology and haematology departments expressed their agreement on 24 statements using a 9-point Likert scale, which were classified as appropriate (median 7-9), uncertain (4-6) or inappropriate (1-3). Consensus was achieved if at least two-thirds of the panel scored within the range containing the median.

RESULTS

With an overall agreement on the current definition of procedural pain, participants suggested a wider description based on evidence and their clinical experience. A strong consensus was achieved regarding the need for a comprehensive pre-procedural pain assessment and experts emphasised that healthcare professionals involved in procedural pain management should be adequately trained. Most panellists (98.2%) agreed that pharmacological treatment should be chosen considering the duration of the procedure. Transmucosal fentanyl (96.5%) and morphine (71.7%) were recommended as the most appropriate drugs. Oral and nasal transmucosal fentanyl were agreed as the most suitable for both outpatients and inpatients, while consensus was reached for intravenous and subcutaneous morphine for inpatients.

CONCLUSIONS

These results provide updated expert-based recommendations on the definition, prevention and treatment of moderate to severe procedural pain, which could inform specialists involved in pain management of patients with cancer.

Localized Drug Delivery Systems: An Update on Treatment Options for Head and Neck Squamous Cell Carcinomas

Head and neck squamous cell carcinoma (HNSCC) is one of the most common cancers in the world, with surgery, radiotherapy, chemotherapy, and immunotherapy being the primary treatment modalities. The treatment for HNSCC has evolved over time, due to which the prognosis has improved drastically. Despite the varied treatment options, major challenges persist. HNSCC chemotherapeutic and immunotherapeutic drugs are usually administered systemically, which could affect the patient's quality of life due to the associated side effects. Moreover, the systemic administration of salivary stimulating agents for the treatment of radiation-induced xerostomia is associated with toxicities. Localized drug delivery systems (LDDS) are gaining importance, as they have the potential to provide non-invasive, patient-friendly alternatives to cancer therapy with reduced dose-limiting toxicities. LDDSs involve directly delivering a drug to the tissue or organ affected by the disease. Some of the common localized routes of administration include the transdermal and transmucosal drug delivery system (DDSs). This review will attempt to explore the different treatment options using LDDSs for the treatment of HNSCC and radiotherapy-induced damage and their potential to provide a better experience for patients, as well as the obstacles that need to be addressed to render them successful.

Breakthrough cancer pain in the radiotherapy setting: a systematic and critical review

INTRODUCTION

Breakthrough pain (BP) is a complex phenomenon that has been reported to have a relevant role in the global management of cancer pain. Radiotherapy (RT) has a fundamental part in the treatment of many pain conditions, particularly oral mucositis and painful bone metastases.

AREAS COVERED

The literature regarding the phenomenon of BP in the radiotherapy setting was reviewed. Three areas were assessed, including epidemiology, pharmacokinetics, and clinical data.

EXPERT OPINION

Qualitative and quantitative data regarding BP in the RT setting are poor in terms of scientific evidence. Most papers assessed fentanyl products, particularly fentanyl pectin nasal spray, to resolve possible problems with transmucosal absorption of fentanyl due to mucositis of the oral cavity in patients with head and neck cancer or to prevent and treat procedural pain during RT sessions. According to the lack of clinical studies with large number of patients, BP should be included in the agenda of radiation oncologists.

Radiation-Induced Oral Mucositis in Head and Neck Cancer Patients. Five Years Literature Review

Backround: Radiation-induced oral mucositis consists of a series of relatively frequent side effects after head and neck cancer radiotherapy and has an adverse impact on both regular treatment process and the quality of life of patients.

OBJECTIVE

The purpose of the present review is to optimize the current management of radiation-induced oral mucositis in head and neck cancer patients.

METHODS

PubMed database research was performed on articles published since 2015 that demonstrated efficacy in the management of radiation-induced oral mucositis in head and neck cancer patients. The study selection included observational, prospective, comparative, randomized, double- blind, placebo-controlled or uncontrolled, and retrospective studies, as well as systematic reviews and metanalyses.

RESULTS

From the 931 citations obtained from the search, only 94 articles met the inclusion criteria, including mucosal protectants, anti-inflammatory agents, growth factors, and various miscellaneous and natural agents. Several methods, including both pharmacological and natural agents, have been proposed for the management of oral mucositis. In addition to the already known interventions with strong evidence, according to the Multinational Association of Supportive Care in Cancer and he International Society of Oral Oncology guidelines, further agents have been used. However, a great number of them lack clear evidence, which surely requires the design of more controlled clinical trials for a better assessment of the ideal methods.

CONCLUSION

The management of oral mucositis constitutes an active area of research. In light of these results, it is aimed to illustrate those treatment strategies that are most effective regarding the treatment approach of oral mucositis.

Effectiveness of fentanyl pectin nasal citrate in controlling episodes of breakthrough cancer pain triggered by routine radiotherapy procedures

PURPOSE

The aim of the study was to evaluate the effectiveness of fentanyl pectin nasal spray (FPNS) in controlling procedural breakthrough cancer pain (BTCP) in advanced cancer patients undergoing radiotherapy.

MATERIALS AND METHODS

This study involved 62 advanced cancer patients, with well-controlled background pain, who presented BTCP associated to routine radiotherapy procedures, treated with FPNS according to our protocol of administration. The BPE intensity was measured using a visual analog scale (VAS).

RESULTS

The BTCP was triggered during the computed tomography simulation (79.3%) or treatment delivery (20.7%). Patients indicated a mean VAS of 8.8 (range 7-10) when attempting the procedure. After 4.5 min (range 2-10) of the first FPNS dose, the majority of patients (85.5%) indicated a VAS of 4.3 (range 2-6). 15.5% of the patients did not respond after 15 min; requiring a second dose. All these patients responded, reporting a mean VAS of 4.2 (range 4-6) after 3.0 min (range 2-5) of the second dose. None of the patients required a third dose, nor reported an AE after the administration of FPNS.

CONCLUSIONS

In our knowledge, our study is the one of highest recruitment, and with the fastest response of BTCP treated with FPNS reported in advanced cancer patients undergoing radiotherapy. FPNS has proven to be highly effective in reducing the intensity of procedural BTCP in a very short period of time.

The use of fentanyl in pain management in head and neck cancer patients: a narrative review

Background

Head and neck (H&N) cancers account for about 5% of all malignant tumours. Pain is one of the most feared consequences of H&N neoplasms and is experienced by up to 80% of patients and worsens their quality of life inhibiting speaking, eating, drinking or swallowing. Nevertheless, pain is still often underestimated and undertreated.

Objectives

The role of opioids in cancer pain has been well established but evidences about the role and the relative effectiveness of opioids such as fentanyl in the context of H&N cancer pain remains unclear.

Methods

A literature review based on the guidance of the Centre for Reviews and Dissemination was conducted. An iterative approach was used starting with an electronic search in the MEDLINE database. The search terms (('Neoplasms'[Mesh]) AND 'Head and Neck Neoplasms'[Mesh]) AND 'Fentanyl'[Mesh] were used.

Results

A total of 18 publications were found by the first performed search on PubMed. Other publications concordant with our aim were found by cross-reference. Considering inclusion and exclusion criteria for our review, eight papers resulted eligible for analysis.

Conclusion

Fentanyl transdermal therapeutic system (TTS) seems to be an important option, thanks to the way of administration, the good safety and tolerability profiles to control baseline pain. For breakthrough cancer pain (BTcP), several formulations of transmucosal fentanyl are available. All the formulations seem to be active and safety but we lack head-to-head studies of fentanyl versus other strong opioids, as well as with different formulation of fentanyl, particularly for BTcP where H&N cancer population is very poorly represented.
