On the receiving end: have patient perceptions of the side-effects of cancer chemotherapy changed since the twentieth century?

Background Studies in 1983 and 1993 identified and ranked symptoms experienced by cancer patients receiving chemotherapy. We repeated the studies to obtain updated information on patient perceptions of chemotherapy-associated symptoms. Patients and methods A cross-sectional interview and patient-reported outcome questionnaires were administered to out-patients receiving chemotherapy. Patients selected from 124 cards to identify and rank the severity of physical and non-physical symptoms they had experienced and attributed to chemotherapy (primary endpoint). The patient’s medical oncologist and primary chemotherapy nurse were invited to rank the five symptoms they believed the patient would rank as their most severe. We analysed the association of symptoms and their severity with patient demographics, chemotherapy regimen, and patient-reported outcomes. Results were compared to the earlier studies. Results Overall, 302 patients completed the interview: median age 58 years (range 17–85); 56% female; main tumour types colorectal 81 (27%), breast 67 (22%), lung 49 (16%); 45% treated with curative intent. Most common symptoms (reported by >50%) were: alopecia, general weakness, effects on family/partner, loss of taste, nausea, fatigue, difficulty sleeping, effects on work/home duties, and having to put life on hold. The most severe symptoms (ranked by >15% in top five) were: concern about effects on family/partner, nausea, fear of the future, fatigue, not knowing what will happen, putting my life on hold, and general weakness. Perceptions of doctors and nurses of patients’ symptom severity closely matched patients’ rankings. Conclusions Compared to earlier studies, there was an increase in non-physical concerns such as effects on family and future, and a decrease in physical symptoms, particularly vomiting, but nausea, fatigue and general weakness remained bothersome. Highlights • Symptoms related to chemotherapy have changed over time, likely due to less toxic regimens and improvements in supportive care. • Effects on family/partner, fear of the future, not knowing what will happen, and “life on hold” were major issues for patients. • Vomiting has decreased but nausea, fatigue and general weakness remain common symptoms for chemotherapy patients.

Does Clear Aligner Treatment Result in Different Patient Perceptions of Treatment Process and Outcomes Compared to Conventional/Traditional Fixed Appliance Treatment: A Literature Review

This study sought to systematically review the literature to determine whether clear aligner treatment results in different patient perceptions of treatment process and outcomes compared with conventional fixed appliance treatment. A systematic review was conducted to identify studies that examined differences in patient perceptions between clear aligners and conventional fixed appliance treatment. Studies were identified through searching relevant terms using PubMed and Embase. Following review of identified articles, key information about the studies including study design, setting, comparison groups, sample size/response rate, study location, primary outcomes, and statistical tests used were extracted. A total of 13 articles were identified that met the inclusion criteria for this study. These studies described a variety of outcomes which were divided into two broad categories: treatment process (pain, chewing, speech, daily routine, etc.) and treatment outcomes (satisfaction level, smile outcome perceptions, etc.). There was the strongest evidence that clear aligners had a positive impact with respect to treatment process compared with fixed orthodontic appliances. This study highlights that clear aligners may be effective for improving treatment-process-related outcomes among orthodontic patients. More studies need to be conducted to determine whether clear aligners have a beneficial impact with respect to treatment outcomes.
