Movement-evoked Pain versus Pain at Rest in Postsurgical Clinical Trials and in Meta-analyses: An Updated Systematic Review.

BACKGROUND: Given the widespread recognition that postsurgical movement-evoked pain is generally more intense, and more functionally relevant, than pain at rest, the authors conducted an update to a previous 2011 review to re-evaluate the assessment of pain at rest and movement-evoked pain in more recent postsurgical analgesic clinical trials. METHODS: The authors searched MEDLINE and Embase for postsurgical pain randomized controlled trials and meta-analyses published between 2014 and 2023 in the setting of thoracotomy, knee arthroplasty, and hysterectomy using methods consistent with the original 2011 review. Included trials and meta-analyses were characterized according to whether they acknowledged the distinction between pain at rest and movement-evoked pain and whether they included pain at rest and/or movement-evoked pain as a pain outcome. For trials measuring movement-evoked pain, pain-evoking maneuvers used to assess movement-evoked pain were tabulated. RESULTS: Among the 944 included trials, 504 (53%) did not measure movement-evoked pain (vs. 61% in 2011), and 428 (45%) did not distinguish between pain at rest and movement-evoked pain when defining the pain outcome (vs. 52% in 2011). Among the 439 trials that measured movement-evoked pain, selection of pain-evoking maneuver was highly variable and, notably, was not even described in 139 (32%) trials (vs. 38% in 2011). Among the 186 included meta-analyses, 94 (51%) did not distinguish between pain at rest and movement-evoked pain (vs. 71% in 2011). CONCLUSIONS: This updated review demonstrates a persistent limited proportion of trials including movement-evoked pain as a pain outcome, a substantial proportion of trials failing to distinguish between pain at rest and movement-evoked pain, and a lack of consistency in the use of pain-evoking maneuvers for movement-evoked pain assessment. Future postsurgical trials need to (1) use common terminology surrounding pain at rest and movement-evoked pain, (2) assess movement-evoked pain in virtually every trial if not contraindicated, and (3) standardize movement-evoked pain assessment with common, procedure-specific pain-evoking maneuvers. More widespread knowledge translation and mobilization are required in order to disseminate this message to current and future investigators.

Nonopioid drug combinations for cancer pain: a systematic review.

Pain is highly prevalent in patients with cancer-nearly 40% report moderate-severe pain, which is commonly treated with opioids. Increasing cancer survivorship, opioid epidemics in some regions of the world, and limited opioid access in other regions have focused attention on nonopioid treatments. Given the limitations of monotherapy, combining nonopioids-such as antiepileptics and antidepressants-have shown promise in noncancer pain. This review seeks to evaluate efficacy of nonopioid combinations for cancer-related pain. Systematic searches of PubMed, EMBASE, and Cochrane CENTRAL were conducted for double-blind, randomized, controlled trials comparing a nonopioid combination with at least one of its components and/or placebo. This search yielded 4 randomized controlled trials, published between 1998 and 2019 involving studies of (1) imipramine + diclofenac; (2) mitoxantrone + prednisone + clodronate; (3) pentoxifylline + tocopherol + clodronate; and (4) duloxetine + pregabalin + opioid. In the first 3 of these trials, trends favouring combination efficacy failed to reach statistical significance. However, in the fourth trial, duloxetine + pregabalin + opioid was superior to pregabalin + opioid. This review illustrates recognition for the need to evaluate nonopioid drug combinations in cancer pain, although few trials have been published to date. Given the growing practice of prescribing more than 1 nonopioid for cancer pain and the need to expand the evidence base for rational combination therapy, more high-quality trials in this area are needed.

Redefining postmastectomy radiation contouring in the era of immediate breast reconstruction: An accurate assessment of local recurrence risk.

INTRODUCTION: Most studies report post-mastectomy local recurrences as chest wall recurrences without clarifying whether the recurrence is in the subcutaneous tissue, muscle or underlying rib. Post-mastectomy chest wall radiation is recommended in patients at increased risk of locoregional recurrence. Chest wall radiation-related fibrosis has become an important clinical consideration in the era of immediate implant-based breast reconstruction. In patients with commonly performed subpectoral implant-based reconstruction, the pectoralis major becomes relocated anterior to the implant and just deep to skin, therefore raising the question of value in radiating deep chest wall structures. This study assessed the rate of recurrence in each anatomical region of chest wall in post-mastectomy patients. METHODS: A comprehensive breast cancer database of 4287 patients at a single regional cancer center from 2006 to 2018 was retrospectively analyzed to identify 1571 mastectomy patients. Recurrences were classified as local skin/subcutaneous, pectoralis muscle (pectoralis major), deep chest wall (pectoralis minor, intercostal muscle or rib) or regional axillary recurrence. RESULTS: A total of 26 patients with locoregional recurrence were identified. Most recurrences were in the skin/subcutaneous level. Of 1571 mastectomy patients, only one patient developed a local recurrence posterior to pectoralis major. Our literature search and meta-analysis revealed that local recurrences post-mastectomy are much more likely to be in subcutaneous tissues/pectoralis major versus deeper chest wall. CONCLUSION: A reduced clinical target volume which encompasses skin/subcutaneous and pectoralis muscle layers without treating deep chest wall may be more appropriate to reduce radiation-associated toxicity since avoiding circumferential radiation of an implant may prevent capsular contracture without compromising treatment benefit.

Electronic forms for patient reported outcome measures (PROMs) are an effective, time-efficient, and cost-minimizing alternative to paper forms.

BACKGROUND: Patient reported outcome measures (PROMs) provide valuable insight on patients' well-being and facilitates communication between healthcare providers and their patients. The increased integration of the technology within the healthcare setting presents the opportunity to collect PROMs electronically, rather than on paper. The Childhood Health Assessment Questionnaire (CHAQ) and Quality of My Life (QoML) are common PROMs collected from pediatric rheumatology patients. The objectives of this study are to (a) determine the equivalence of the paper and electronic forms (e-form) of CHAQ and QoML questionnaires; (b) identify potential benefits and barriers associated with using an e-form to capture PROMs; and (c) gather feedback on user experience. METHODS: Participants completed both a paper and an e-form of the questionnaires in a randomized order, following which they completed a feedback survey. Agreement of the scores between the forms were statistically analyzed using the intraclass correlation coefficient (ICC) (95 % Confidence Interval (CI)) and bias was assessed using a Bland-Altman plot. Completion and processing times of the forms were compared using mean and median measures. Quantitative analysis was performed to assess user experience ratings, while comments were qualitatively analyzed to identify important themes. RESULTS: 196 patients participated in this project. Scores on the forms had high ICC agreement > 0.9. New patients took longer than returning patients to complete the forms. Overall, the e-form was completed and processed in a shorter amount of time than the paper form. 83 % of survey respondents indicated that they either preferred the e-form or had no preference. Approximately 10 % of respondents suggested improvements to improve the user interface. CONCLUSIONS: E-forms collect comparable information in an efficient manner to paper forms. Given that patients and caregivers indicated they preferred completing PROMs in this manner, we will implement their suggested changes and incorporate e-forms as standard practice for PROMs collection in our pediatric rheumatology clinic.

Modulating the endocannabinoid pathway as treatment for peripheral neuropathic pain: a selected review of preclinical studies.

Chemotherapy-induced neuropathic pain is a distressing and commonly occurring side effect of many commonly used chemotherapeutic agents, which in some cases may prevent cancer patients from being able to complete their treatment. Cannabinoid based therapies have the potential to manage or even prevent pain associated with this syndrome. Pre-clinical animal studies that investigate the modulation of the endocannabinoid system (endogenous cannabinoid pathway) are being conducted to better understand the mechanisms behind this phenomenon. Five recent pre-clinical studies identified from Medline published between 2013 and 2016 were selected for review. All studies evaluated the effect of small-molecule agonists or antagonists on components of the endocannabinoid system in rats or mice, using cisplatin or paclitax-el-induced allodynia as a model of chemotherapy-induced neuropathic pain. Activation of the cannabinoid receptor-2 (CB-2) receptor by AM1710 blocked paclitaxel-induced mechanical and cold allodynia in one study. Four studies investigating the activation of both cannabinoid receptor-1 (CB-1) and CB-2 receptors by dual-agonists (WIN55,21 and CP55,940), or by the introduction of inhibitors of endocannabinoid metabolisers (URB597, URB937, JZL184, and SA-57) showed reduction of chemotherapy-induced al-lodynia. In addition, their results suggest that anti-allodynic effects may also be mediated by additional receptors, including TRPV1 and 5-hydroxytryptamine (5-HT1A). Pre-clinical studies demon-strate that the activation of endocannabinoid CB-1 or CB-2 receptors produces physiological effects in animal models, namely the reduction of chemotherapy-induced allodynia. These studies also provide in-sight into the biological mechanism behind the therapeutic utility of cannabis compounds in managing chemotherapy-induced neuropathic pain, and provide a basis for the conduct of future clinical studies in patients of this population.

Symptom clusters using the Brief Pain Inventory in patients with breast cancer.

BACKGROUND: The purpose of this study was to assess symptom clusters in functional interference using the brief pain inventory (BPI) in patients with non-metastatic breast cancer (BC) during and after chemotherapy. METHODS: A principal component analysis with varimax rotation was conducted on data from 228 patients to identify two clusters at baseline and two intervals following treatment. RESULTS: Physical (general activity, normal work, walking ability) and psychosocial (mood, relationships, sleep, enjoyment of life) interference clusters were present at baseline. Clusters were observed at 1-month (cluster 1: general activity, normal work, enjoyment of life; cluster 2: relationships, sleep) and 3-month (cluster 1: general activity, normal work, relationships; cluster 2: sleep, enjoyment of life) post-treatment. CONCLUSIONS: Results from our study suggest dynamic symptom clusters in this patient population, and encourage continued symptom management following completion of treatment.

A selective review of medical cannabis in cancer pain management.

Insufficient management of cancer-associated chronic and neuropathic pain adversely affects patient quality of life. Patients who do not respond well to opioid analgesics, or have severe side effects from the use of traditional analgesics are in need of alternative therapeutic op-tions. Anecdotal evidence suggests that medical cannabis has potential to effectively manage pain in this patient population. This review presents a selection of representative clinical studies, from small pilot studies conducted in 1975, to double-blind placebo-controlled trials conducted in 2014 that evaluated the efficacy of cannabinoid-based therapies containing tetrahydrocannabinol (THC) and cannabidiol (CBD) for reducing cancer-associated pain. A review of literature published on Medline between 1975 and 2017 identified five clinical studies that evaluated the effect of THC or CBD on controlling cancer pain, which have been reviewed and summarised. Five studies that evaluated THC oil capsules, THC:CBD oromucosal spray (nabiximols), or THC oromucosal sprays found some evidence of cancer pain reduction associated with these therapies. A variety of doses ranging from 2.7-43.2 mg/day THC and 0-40 mg/day CBD were administered. Higher doses of THC were correlated with increased pain relief in some studies. One study found that significant pain relief was achieved in doses as low as 2.7-10.8 mg THC in combination with 2.5-10.0 mg CBD, but there was conflicting evidence on whether higher doses provide superior pain relief. Some reported side effects include drowsiness, hypotension, mental clouding, and nausea and vomiting. There is evidence suggesting that medical cannabis reduces chronic or neu-ropathic pain in advanced cancer patients. However, the results of many studies lacked statistical power, in some cases due to limited number of study subjects. Therefore, there is a need for the conduct of further double-blind, placebo-controlled clinical trials with large sample sizes in order to establish the optimal dosage and efficacy of different cannabis-based therapies.

An update in symptom clusters using the Edmonton Symptom Assessment System in a palliative radiotherapy clinic.

PURPOSE: To identify symptom clusters in advanced cancer patients attending a palliative radiotherapy clinic using the Edmonton Symptom Assessment System (ESAS). METHODS: Principal component analysis (PCA), exploratory factor analysis (EFA), and hierarchical cluster analysis (HCA) were used to identify symptom clusters among the nine ESAS items using scores from each patient's first visit. RESULTS: ESAS scores from 182 patients were analyzed. The PCA identified three symptom clusters (cluster 1: depression-anxiety-well-being, cluster 2: pain-tiredness-drowsiness, cluster 3: nausea-dyspnea-loss of appetite). The EFA identified two clusters (cluster 1: tiredness-drowsiness-loss of appetite-well-being-pain-nausea-dyspnea, cluster 2: depression-anxiety). The HCA identified three clusters similar to the PCA with an exception of the loss of appetite item being classified under cluster 1 rather than 3. Two to three symptom clusters were identified using three analytical methods, with similar patterns reported in the literature. Particular groups of items co-occurred consistently across all three analyses: depression and anxiety; nausea and dyspnea; as well as pain, tiredness, and drowsiness. CONCLUSION: Three similar symptom clusters were identified in our patient population using the PCA and HCA; whereas, the EFA produced two clusters: one physical and one psychological cluster. Given the implications of symptom clusters in the management of quality of life, clinicians should be aware of these clusters to aid in the palliative treatment of patients.

Use of urinary markers in cancer setting: A literature review.

INTRODUCTION: In bone metastases, the disruption of normal bone processes results in increased resorption and formation rates, which can often be quantitatively measured by biomarkers in the urine and blood. The purpose of this review is to summarize relevant studies of urinary markers used as a diagnostic and/or prognostic tool, as well as its potential and advances in directing therapy. METHODS: A literature search was conducted using Ovid MEDLINE (1950 to July 2014), EMBASE (1950 to 2014 week 30) and Cochrane Central Register of Controlled Trials (3rd Quarter 2014) to identify studies that detailed the use of urinary markers in the cancer setting, specifically involving markers for bone metastases. Search terms included "urinary markers", "cancer", and "bone metastases". RESULTS: A total of 35 articles, with 24 original studies, were identified. In general, urinary markers can be used to detect early signs of bone metastases prior to skeletal imaging, but still must be used in conjunction with imaging to avoid false positive results. The use of urinary markers, such as N-telopeptide, as a prognostic tool remains controversial, but can provide information on the relative risk of skeletal related events (SREs), disease progression, as well as death. Finally, while urinary markers have shown to be potentially useful in confirming the efficacy of bone metastases treatments, exploring the appropriate dosages for treatment, and directing therapy, it is still unclear to what extent urinary markers should be reduced by. CONCLUSION: The potential use of urinary markers in the management of bone metastases is promising as it can allow for earlier and more convenient detection of bone metastases in comparison to other techniques. However, additional studies involving prospective clinical trials are suggested to further examine the potential of urinary markers in developing appropriate treatment strategies and endpoints, especially in developing a clearer protocol on the extent urinary markers should be reduced by to correlate with achievement of clinical benefit.

Symptom clusters of gastrointestinal cancer patients undergoing radiotherapy using the Functional Living Index-Emesis (FLIE) quality-of-life tool.

OBJECTIVE: The Functional Living Index-Emesis (FLIE) instrument is a validated nausea and vomiting specific quality of life (QOL) tool originally created as a 3-day test of the impact of chemotherapy-induced nausea and vomiting on cancer patients' daily life. The primary objective of the present study was to retrospectively explore the use of the FLIE from data obtained in a previously published study of patients with gastrointestinal radiation-induced nausea and vomiting (RINV) and compare the extracted symptom clusters on a weekly basis for the entirety of gastrointestinal cancer patients' radiotherapy treatments. METHODS: QOL was assessed on a weekly basis using the 18-item FLIE questionnaire for patients' radiotherapy treatments. A principal component analysis with varimax rotation was performed at each visit. The internal consistency and reliability of the derived clusters was assessed with Cronbach's alpha. Robust relationship and correlation among symptoms was displayed with biplot graphics. RESULTS: A total of 460 FLIE assessments were completed for the 86 gastrointestinal patients who underwent radiotherapy. Two components were consistently identified except for week 5 where only one component was identified. Component 1 contained the items "Q10-Q18" which included all vomiting items. Component 2 included all nausea items from "Q1 to Q9". All the variables were well accounted for by two components for most weeks of treatment with excellent internal consistency. Biplots indicate that the two symptom clusters were evident at each week, with the exception of the first week of treatment. Strong correlations were seen between the effect of nausea on patients' ability to make meals, patients' ability to do tasks within the home, and patients' willingness to spend time with family and friends. CONCLUSION: The high internal consistency at all timepoints indicates that the FLIE QOL instrument is useful for the RINV population.

Inadequacy of Palliative Training in the Medical School Curriculum.

This report examines the literature on palliative training in the current medical school curriculum. A literature search was conducted to identify relevant articles. Physicians and medical students both report feeling that their training in end-of-life care and in palliative issues is lacking. The literature expresses concerns about the varied and non-uniform approach to palliative care training across medical schools. The authors recommend the development of more palliative training assessment tools in order to aid in the standardization of curriculum involving end-of-life care. In addition, increased exposure to dying patients will aid students in building comfort with palliative care issues. Such a goal may be accomplished through required clerkships or other similar programs.

Comparison of the EORTC QLQ-BN20 and the FACT-Br quality of life questionnaires for patients with primary brain cancers: a literature review.

PURPOSE: This review compares and contrasts the development, validity, and characteristics of two quality of life (QOL) assessment tools used in patients with primary brain cancers: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Brain Cancer Module (EORTC QLQ-BN20) and the Functional Assessment of Cancer Therapy-Brain (FACT-Br). METHODS: A literature search was conducted using the Cochrane Central Register of Controlled Trials (June 2013), Ovid EMBASE (1947 to 2013, week 27), and Ovid MEDLINE (1946 to July 2013, week 1) to identify studies that discussed the development, characteristics, validity, and reliability of the EORTC QLQ-BN20 or the FACT-Br. RESULTS: The EORTC QLQ-BN20 consists of 20 items that assess future uncertainty, visual disorder, motor dysfunction, and communication deficit. Items are presented as questions on a scale ranging from 1 = "not at all" to 4 = "very much." Reliability and validity testing of the QLQ-BN20 revealed a Cronbach's alpha coefficient that ranged from 0.71 to 0.90. The FACT-Br consists of 23 items that assess general well-being and brain cancer-specific concerns that include concentration, memory, seizures, eyesight, hearing, speech, personality, expression of thoughts, weakness, coordination, and headaches. These items are presented as statements on a scale ranging from 0 = "not applicable" to 4 = "extremely relevant." The FACT-Br underwent validity as well as test-retest reliability testing with 101 and 46 patients, respectively. Validity testing found low to moderate correlation with the FACT-G questionnaire, while reliability testing for the brain subscale revealed an acceptable correlation coefficient (r = 0.66; p < 0.001). CONCLUSIONS: The QLQ-BN20 and the FACT-Br are both valid and reliable tools that have been used extensively in the primary brain cancer population. Choice between the two tools should consider each instrument's individual strengths and weaknesses.

A prospective study of gastrointestinal radiation therapy-induced nausea and vomiting.

OBJECTIVE: Nausea and vomiting are common side effects from radiotherapy that can interfere with gastrointestinal (GI) cancer patients' quality of life (QOL). A prospective study among patients with GI cancers was conducted to document the timing, incidence and risk factors of radiation therapy-induced nausea and vomiting (RINV). METHODS: Forty-eight patients planned to receive curative or palliative intent abdominal and/or pelvic radiotherapy alone or with concomitant chemoradiotherapy were followed prospectively. All episodes of nausea, vomiting, retching and antiemetic use were recorded daily for the entire treatment period and for the week following completion of therapy. QOL was assessed weekly using the Functional Living Index--Emesis Quality of Life Tool and the EORTC QLQ-C30 core questionnaire. RESULTS: Nausea occurred in 83 % of patients and emesis in 54 %. Pancreatic cancer was significantly correlated to higher proportions of nausea and emesis (p = 0.002 and p = 0.0003) compared to other primary sites. There were no significant difference between concomitant chemoradiotherapy and radiotherapy only patients for nausea and emesis. Patients had significantly greater proportions of RINV during the first, second and fifth weeks of treatment and during the first week following treatment. Vomiting was found to impair patients' usual recreation or leisure activities and enjoyment of their meals. Worse physical, role and social functioning and greater fatigue and appetite loss over the course of treatment correlated directly with the timing of RINV symptoms. CONCLUSION: RINV worsened QOL and was experienced even after treatment was completed; physicians should therefore be cognizant and monitor patients in the week following radiotherapy. Concomitant chemoradiotherapy should potentially be included in the moderate emetogenic risk category.

Adverse events across generations of bone-modifying agents in patients with solid tumor cancers reported in Phase III randomized trials.

AIMS: The objective of this study is to compare adverse events experienced among different bone-modifying agents. METHODS: A literature search was conducted to identify Phase III bisphosphonate and bone-modifying agent trials reporting adverse effects. Thirty-seven adverse events of interest were identified for six different treatment options. Weighted linear regression modeling was performed on the adverse event proportions with treatment groups, normalized through applying natural log transformations. RESULTS: There were significant differences in adverse events of vomiting (p = 0.045) and osteonecrosis of the jaw (p = 0.017), and combined item events of nausea/vomiting (p = 0.048), hematological and lymphatic system toxicities (p = 0.020), and any respiratory system problem (p = 0.023) between bone-modifying agent and placebo trials. The significant toxicities were observed even after adjusting for the two confounding factors of age and primary cancer site. CONCLUSION: While adverse effects are consistently experienced more frequently in patients receiving bone-modifying agents when compared with placebos, we find that the majority of individual side effects are not significantly more frequent in patients receiving bone-modifying agents compared with placebo.

The impact of clinical and sociodemographic features on quality of life in patients with early stage cancers using the Functional Assessment of Cancer Therapy-General assessment tool.

PURPOSE: This study aims to compare the Functional Assessment of Cancer Therapy-General (FACT-G) quality of life (QOL) scores of patient groups with varying clinical and sociodemographic features in the early stage cancer population. METHODS: A literature search was conducted on both the Embase and OvidSP platforms. Weighted analysis of variance (ANOVA) was performed for binary predictors and weighted linear regression analysis was conducted for continuous predictors. RESULTS: Six binary features predicted at least one domain of QOL: primary cancer site (homogeneous versus heterogeneous), total per capita healthcare expenditures, mean age, previous chemotherapy, radiotherapy, and previous hormonal therapy. Two continuous factors had predictive value with respect to QOL: completion of postsecondary education and marital status. CONCLUSION: Although there are limitations of the current study, similar correlations to our own have been previously described between QOL and healthcare expenditures, mean age and education. Currently, the literature conflicts in its analysis of previous radiotherapy and chemotherapy as predictors of QOL. No published evidence exists describing the presently found relationships in primary cancer site, marital status and hormonal therapy. Future work may focus on determining cause and effect relationships between these predictors and QOL.

Quality of Life in Patients with Advanced Cancer Using the Functional Assessment of Cancer Therapy-General Assessment Tool: A Literature Review.

Quality of life (QOL) has become an increasingly meaningful endpoint in advanced cancer research. Clinicians assess QOL to help them select appropriate treatment options and regimens. The present review aims to compare QOL scores of the Functional Assessment of Cancer Therapy-General Assessment Tool (FACT-G) in relation to clinical and socio-demographic features in patients with advanced cancer. A literature search in MEDLINE and EMBASE was conducted; a total of 33 studies encompassing 39 study arms were identified that reported FACT-G scores. Four statistically significant parameters were identified with respect to FACT-G scores: education, national per capita healthcare expenditures, admittance status and previous radiation therapy. A greater percentage of patients completing higher education programs were correlated to significantly better emotional well-being and global QOL. Cohorts from countries with higher national per capita healthcare expenditures had better physical well-being, social/family well-being and improved relationships with their doctors. Patient samples comprised of purely outpatients had better levels of emotional well-being and global QOL when compared to samples with a mix of outpatients and inpatients. A greater percentage of patients previously receiving radiation therapy were correlated to a better relationship with doctor score. Although limitations of the present review exist, differences in QOL scores based on socio-demographic and clinical factors are observed; certain correlations described in the present work have been described previously in the literature while others have not. Future work aimed at either determining confounding parameters or cause and effect relationships is recommended.

The utilization of telephone follow-up in the advanced cancer population: a review of the literature.

BACKGROUND: Palliative cancer patients often require clinic or hospital follow-up after any treatment intervention they may have received. This is typically done in person at either a hospital or a clinic. In these advanced cancer patients, this may be burdensome and result in attrition. Telephone follow-up is becoming more frequently used as an adjunct to clinical follow-up. It can be conducted for both clinical trials, as well as interventional purposes. The purpose of this study was to review the literature and examine the utility and effectiveness of telephone follow-up in the advanced cancer population. METHODS: A literature search was conducted on Medline (1980 - April week 4 2012), Embase (1980 - week 17 2012), the Cochrane Central Register of Controlled Trials (April 2012) and CINAHL (1981-July 31 2012). RESULTS: A total of 11 studies were identified that were published between 2001 and 2011. All studies were in the clinical trial setting. Studies that utilized telephone follow-up in the advanced cancer population, as well as studies that compared the feasibility of telephone follow-up with hospital follow-up, were included in this review. Follow-up at week 4 (month 1) was the most common interval for patient contact. Information collected during the contact varied with the study; however, the most commonly used tool was the Edmonton Symptom Assessment System. Other information included analgesic diary, patient feedback, satisfaction with the care and post-treatment side effects, along with a variety of quality of life questionnaires. Some studies provided information to the patient about protocols for care, advice and coping strategies. Attrition was common even with the use of telephone contact in place of clinical follow-up. CONCLUSION: Telephone follow-up is a feasible alternative to traditional hospital follow-ups for assessment of symptom palliation. There are fewer burdens on the patient, allowing for a better maintenance of quality of life and lower rates of attrition in clinical trials. Patients had an overall positive opinion of the use of this alternative approach with no common disadvantages. A combination of follow-up strategies, such as clinic follow-up and telephone contact for those not attending, may result in a more comprehensive assessment.
