Inter-rater reliability of the Oral Assessment Guide for oral cancer patients between nurses and dental hygienists: methodological issue


Are topical beta-blockers really effective "in real life" for targeted therapy-induced paronychia

Abstract

Paronychia and periungual pyogenic granuloma represent one of the most common and bothersome dermatologic toxicities observed with ErbB inhibitors. There is no standardized treatment, and management remains challenging. Moreover, conservative management with noninvasive treatment should be promoted for fragile patients in a metastatic setting. Over the last few years, the efficacy of topical blocking agents has been considered for managing cutaneous or mucosal pyogenic granulomas. Very recently, the use of topical propranolol or of timolol has been reported in several patients undergoing treatment with EGFR inhibitors and developing pyogenic granulomas of the nail. We performed a retrospective single-center review of patients with targeted therapy-related paronychia/periungual pyogenic granulomas who had been treated with topical timolol, either alone or in combination with other topical treatments. Nearly two thirds of patients showed at least a partial response after 1 month of therapy, and the use of a topical beta-blocker in our population was associated with a favorable safety profile. Finally, topical timolol may represent a promising treatment option for the management of cancer patients suffering from painful periungual lesions. Comparative clinical trials, however, are still needed.



Social support buffers against anxiety and depressive symptoms in patients with cancer only if support is wanted: a large sample replication


Combined exercise and nutritional rehabilitation in outpatients with incurable cancer: a systematic review

Abstract

Purpose

The optimal components for rehabilitation in patients with incurable cancer are unclear. However, principles of exercise and nutrition-based interventions used in cancer cachexia may be applied usefully to this population of cancer patients. This systematic review examines current evidence for rehabilitation combining exercise and nutritional support in patients with incurable cancer.

Methods

MEDLINE, EMBASE and Cochrane databases were searched. Eligible studies included patients with incurable cancer and rehabilitation programmes combining exercise and nutritional interventions. Studies of cancer survivors, curative treatments, reviews, case note reviews, protocols and abstracts were excluded. Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria were applied to patient-important outcomes.

Results

Of the 2424 search results, 67 abstracts were reviewed and 24 full texts examined. Eight studies (n = 685) were included comprising two randomised control trials, three prospective, one exploratory and two secondary analyses. All examined multi-modal outpatient programmes. GRADE analysis revealed moderate evidence (B) for improvements in depression and physical endurance, low-quality evidence (C) for quality of life and fatigue and very low–quality evidence (D) for overall function and nutritional status.

Conclusion

There are limited data for multi-modal rehabilitation programmes combining exercise and nutritional interventions in patients with incurable cancer. However, studies to date report improvements in multiple domains, most notably physical endurance and depression scores. This supports the concept that multi-modal rehabilitation incorporating principles of cachexia management may be appropriate for the wider group of patients with incurable cancer. Further, high-quality studies are needed to define the optimal approach and outcome measures.



Toward the development of a comprehensive cancer experience measurement framework

Abstract

A diagnosis of cancer and its treatment often have a profound impact on an individual's health-related quality of life—affecting physical, psychological, social, occupational, and financial domains. Person-centered care (PCC)—defined as a respectful, responsive, and tailored approach that meets patients' needs, values, and preferences—is becoming an integral part of comprehensive cancer care. The implementation of PCC into clinical practice provides benefits such as improvement in the quality of patient care, enhanced health-related outcomes, and significantly higher satisfaction with care. However, to guide and document more precisely the effects of PCC, various authors have argued that a more comprehensive measurement framework is needed. The primary goal of this paper is to present such an evolving framework based on extant evidence and developed in the context of a series of expert stakeholder meetings spearheaded by the Canadian Partnership Against Cancer (CPAC) that began in 2012. Developed collaboratively, the Cancer Experience Measurement Framework goes beyond existing patient experience frameworks by focusing on four key elements and related measures: the patient perspective, the family perspective, the combined patient-family perspective, and interactions with the healthcare system. In light of current healthcare trends promoting cancer self-management, patients as partners, and patient and family engagement in care, it is imperative that we conduct ongoing assessments using shared and psychometrically sound measures to ensure sound comparisons across settings, as well as better cancer-related processes and outcomes for indivduals affected by cancer.



Sensorimotor training and whole-body vibration training have the potential to reduce motor and sensory symptoms of chemotherapy-induced peripheral neuropathy—a randomized controlled pilot trial

Abstract

Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and clinically relevant side effect of chemotherapy. The symptoms diminish patients' quality of life and represent a decisive limiting factor for medical therapy. To date, effective treatment options are lacking. Specific exercise interventions have proven promising to target relevant symptoms. We conducted a prospective, four-armed, randomized, controlled trial, to evaluate the effects of sensorimotor training (SMT) and whole-body vibration training (WBV) on patients with CIPN. Participants (N = 40) were randomized to either one of two intervention groups (SMT N = 10 or WBV N = 10) or oncological control group (N = 10) and matched by gender and age with a healthy control (N = 10). The intervention groups exercised twice a week for 6 weeks. Primary endpoint was the reduction of CIPN-related symptoms (improve peripheral deep sensitivity, Achilles tendon reflex (ASR) and patellar tendon reflex (PSR), light-touch perception, sense of position, and lower leg strength). Secondary endpoints were nerve conduction velocity and amplitude, balance control, quality of life, and CIPN-related pain. Patients exercising improved sensory and associated motor symptoms. Significant intergroup differences were found for the tendon reflexes (ASR P = .017 and PSR P = .020), peripheral deep sensitivity (P = .010), and pain (P = .043). Furthermore, tendencies were found regarding the subjective improvement of symptoms (P = .075) and two subscales of the EORTC-QLQ-C30 questionnaire: pain (P = .054) and dyspnea (P = .054). The results for the SMT group were superior regarding the tendon reflexes, and a tendency regarding the subjective report of symptoms, while WBV was superior regarding pain. SMT and WBV behold a large potential to reduce CIPN-related symptoms and can be considered feasible and safe for patients with CIPN (compliance 97.5%, no adverse events).

Sexual desire of French representative prostate cancer survivors 2 years after diagnosis (the VICAN survey)

Abstract

Purpose

The prostate cancer impacts on the future life of survivors. The complexity of sexual health problems in prostate cancer survivors is underestimated or often reduced to the erectile dysfunction. Especially, factors influencing sexual desire of patients have to be more explored. This study aims to describe the therapeutic management of patients with prostate cancer and assess their sexual desire 2 years after diagnosis.

Methods

This study is part of the National VICAN survey (Vie après le CANcer) implemented in France in 2012. This analysis was performed on a population of 414 men who had prostate cancer. The questionnaire dealt with several topics including socioeconomic status, treatments received, and sexual desire.

Results

Prostatectomy (42.8%), radiotherapy + hormonotherapy (17.6%), and radiotherapy alone (12.8%) were the main treatments used. 41.3% of men stated that their sexual desire was all gone since disease. The "satisfying" perceived financial situation was significantly associated to a sexual desire loss (p = 0.008). Radiotherapy + hormonotherapy treatment only is significantly associated with a loss of sexual desire (P = 0.003).

Conclusions

Two years after diagnosis, the sexual desire of prostate cancer survivors is deteriorated with the cancer experience. However, clinical characteristics do not seem to be decisive unlike a "satisfying" financial situation. Research about the impact of socio economics characteristics on sexual health should probably be engaged. Programs have to be developed in France to have personalized sexual support progressed for survivors and take spouses into consideration in this context.



Early 7-day supplemental parenteral nutrition improves body composition and muscle strength in hypophagic cancer patients at nutritional risk

Abstract

Purpose

The international guidelines recommend the use of supplemental parenteral nutrition (SPN) in cancer patients when they are malnourished and hypophagic and where enteral nutrition is not feasible. However, there are limited data on the short-term effects of SPN in this patient population.

Methods

The aim of this bicentric single-arm clinical trial (NCT02828150) was to evaluate the effects of early 7-day SPN on bioimpedance vectorial analysis (BIVA)–derived body composition, handgrip strength (HG), and serum prealbumin (PAB) in 131 hypophagic, hospitalized cancer patients at nutritional risk, with contraindications for enteral nutrition.

Results

One hundred eighteen patients (90.1%) completed the 7-day SPN support regimen and 102 of them (86.4%) were in advanced disease stage.

SPN induced a significant improvement of phase angle (PhA, + 0.25 [95% CI 0.11, 0.39]; p = 0.001), standardized phase angle (SPA, + 0.33 [95% CI 0.13, 0.53]; p = 0.002), HG (+ 2.1 kg -95% CI 1.30, 2.81]; p < 0.001), and PAB (+ 3.8 mg/dL [95% CI 2.1, 5.6]; p < 0.001).

In multivariable analysis, the effects on BIVA parameters were more pronounced in patients (N = 90, 76.3%) in whom estimated protein and calorie requirements were both satisfied (adjusted difference: PhA, + 0.39 [95% CI 0.04, 0.73]; p = 0.030; SPA, + 0.62 [95% CI 0.16, 1.09]; p = 0.009).

No significant changes in hydration status were detected and no severe metabolic or other complications occurred.

Conclusions

Early 7-day SPN resulted in improved body composition, HG and PAB levels in hypophagic, and hospitalized cancer patients at nutritional risk in the absence of any relevant clinical complications. Further trials, aimed at verifying the efficacy of this early nutritional intervention on mid- and long-term primary clinical endpoints in specific cancer types, are warranted.



Early Skeletal Muscle Loss in Non-Small Cell Lung Cancer Patients Receiving Chemoradiation and Relationship to Survival

Abstract

Purpose

Sarcopenia is associated with reduced survival in cancer. Currently, data on sarcopenia at presentation and muscle loss throughout treatment are unknown in patients receiving chemoradiation therapy (CRT) for non-small cell lung cancer (NSCLC). This study evaluated skeletal muscle changes in NSCLC patients receiving CRT and relationship with survival.

Methods

Secondary analysis of 41 patients with NSCLC treated with CRT assessed for skeletal muscle area and muscle density by computed tomography pre-treatment and 3 months post-treatment. Images at week 4 of treatment were available for 32 (78%) patients. Linear mixed models were applied to determine changes in skeletal muscle over time and related to overall survival using Kaplan-Meier plots.

Results

Muscle area and muscle density decreased significantly by week 4 of CRT (− 6.6 cm2, 95% CI − 9.7 to − 3.1, p < 0.001; − 1.3 HU, 95% CI − 1.9 to − 0.64, p < 0.001, respectively), with minimal change between week 4 of CRT and 3 months post-CRT follow-up (− 0.2 cm2, 95% CI − 3.6–3.1, p = 0.91; − 0.27, 95% CI − 0.91–0.36, p = 0.36, respectively). Sarcopenia was present in 25 (61%) and sarcopenic obesity in 6 (14%) of patients prior to CRT, but not associated with poorer survival. Median survival was shorter in patients with low muscle density prior to treatment although not statistically significant (25 months + 8.3 vs 53 months + 13.0, log-rank p = 0.17).

Conclusion

Significant loss of muscle area and muscle density occurs in NSCLC patients early during CRT. A high proportion of patients are sarcopenic prior to CRT; however, this was not significantly associated with poorer survival.



Factors influencing neck and shoulder function after oral oncology treatment: a five-year prospective cohort study in 113 patients

Abstract

Background

The aim of this study was to identify factors influencing shoulder and/or neck function in patients up to five years after treatment.

Materials and methods

Lateral flexion of the neck, ipsilateral forward flexion, and abduction of the shoulder were measured. Potential factors were entered into a linear mixed model analysis to create a multivariate model for describing the results.

Results

Predicted neck and shoulder function was negatively influenced by higher age before intervention. Contralateral flexion of the neck was lower for patients undergoing surgery and radiotherapy compared to surgery. Ipsilateral flexion of the neck is influenced by a higher age at baseline. Ipsilateral shoulder abduction is lower for female gender, bone graft/flap reconstruction, and more extensive neck dissection. Ipsilateral forward flexion of the shoulder is lower for bone graft/flap reconstruction and better for patients with a T2 tumor in comparison to T3 and T4 tumors, as predicted.

Conclusion

By our five-year follow-up outcomes of this study, neck and/or shoulder impairments can be found for high-risk patients by physiotherapists.
