The aim of this study was to analyze the quality of life of patients with advanced rectal cancer before and during the COVID-19 pandemic and to determine whether the pandemic affected patients’ quality of life. The study included 389 patients and was performed from May 2010 to June 2021. The fifteen months from March 2020 to June 2021 were categorized as the COVID-19 period. Patients were surveyed using the QLQ-C30 and QLQ-CR38 questionnaires. The questionnaires were used at different phases of radiochemotherapy: prior to RCT (day 1), during RCT (day 14), at the end of RCT (day 35), and prior to mesorectal surgery (day 70). Scores were formed from the questions. In addition, scores were analyzed for different age groups (64) and sexes (female and male). Overall, patients reported lower functional scores and higher symptom scores during the pandemic than before the pandemic. Although it had been expected that older and younger patients would differ clearly, there were only minor differences. The comparison between the two sexes showed very different scores, with female patients having lower functional scores and higher symptom scores than male patients before and especially during COVID-19. In conclusion, age does not play a major role in quality of life, but sex does play an important role in perception of functioning and symptoms. COVID-19 also had a major impact on patients’ lives, as it was a very isolating and stressful time for everyone, especially cancer patients, which was reflected in worsening scores.

Colorectal cancer remains one of the most commonly diagnosed cancers. Advanced rectal cancer patients receive neoadjuvant radiochemotherapy as well as surgery and suffer from reduced health-related quality of life due to various side effects. We were interested in the role of the COVID-19 pandemic and how it affected those patients’ quality of life. A total of 489 advanced rectal cancer patients from the University Hospital Erlangen in Germany were surveyed between May 2010 and March 2022 and asked to fill out the EORTC QLQ-C30 and QLQ-CR38 questionnaires over eight different time points: at the beginning, during and after radiochemotherapy, right before surgery, and in yearly intervals after surgery for up to four years. Answers were converted to scores to compare the COVID-19 period to the time before March 2020, focusing on the follow-ups, the developments over time—including by sex and age—and the influence of the TNM cT-stage. Overall, a trend of impaired functional and symptom scores was found across all surveys with few significances (body image −10.6 percentage points (pp) after one year; defecation problems +13.5 pp, insomnia +10.2 pp and weight loss +9.8 pp after three years; defecation problems +11.3 pp after four years). cT4-stage patients lost significantly more weight than their cT1-3-stage counterparts (+10.7 to 13.7 pp). Further studies should be conducted to find possible causes and develop countermeasures for future major infectious diseases.

Background/Objectives: Advanced rectal cancer is one of the most common cancers worldwide and has a significant impact on public health. Because favorable and long-term survival has been achieved with multimodal therapy, patient quality of life is very important. The intention of this study was to assess patients’ quality of life using various functioning and symptom scores from the years 2010 to 2022 and to examine changes over time. Methods: Data on health-related quality of life were collected from rectal cancer patients treated at the University Hospital Erlangen in Germany over a period of 13 years. The EORTC QLQ-C30 questionnaire and the rectal cancer-specific module QLQ-CR38 were completed in this study by a total of 516 patients. The questionnaires were collected before, during and at annual follow-up visits after treatment. Statistical significance was defined as p-values < 0.05 as well as a difference of 10 or more percentage points. Results: The deterioration in scores is most pronounced immediately after radiochemotherapy, especially for pain (+19.8 pp), fatigue (+16.1 pp) and diarrhoea (+24.8 pp). One year after the end of therapy, most of the values are again comparable to or better than those of the German general population and only role functioning (−19.8 pp), social functioning (−24.6 pp), diarrhoea (−21.6 pp) and financial difficulties (−16.3 pp) are considerably worse. Some baselines deteriorate clearly over time from 2010 to 2022; these are role functioning (−23.9 pp), social functioning (−17.3 pp), body image (−15.2 pp), fatigue (+13.8 pp) and nausea and vomiting (+10.5 pp). Conclusions: An improvement in therapy in terms of a reduction in side effects and, thus, an improvement in quality of life over time could not be proven. The deterioration in individual scores over time does not appear to be a problem specific to rectal cancer patients, but rather, is associated with social developments or systemic healthcare factors in German society that are not directly related to oncological diseases.

Background/Objectives: Quality of life (QoL) is a valuable tool for evaluating treatment outcomes and identifying patients who may benefit from early supportive interventions. This study aimed to determine whether specific QoL results in patients with advanced rectal cancer could identify groups with an unfavourable prognosis in long-term follow-up. Methods: A total of 570 patients with advanced rectal cancer were prospectively assessed, during and up to five years after neoadjuvant radiochemotherapy, using the QLQ-C30 and QLQ-CR38 questionnaires. We analysed 27 functional and symptom-related scores to identify associations with overall survival, once at baseline, three times during therapy, and annually from years one to five post-therapy. Results: Poor quality of life scores were consistently associated with shorter overall survival. The functional scores of physical functioning, role functioning, and global health, as well as the symptom scores of fatigue, dyspnoea, and chemotherapy side effects, were highly significant for overall survival at nearly all time points except for the immediate preoperative assessment. Patients over the age of 64 with lower QoL scores showed a significantly reduced probability of survival in the follow-up period, and patients who reported poor QoL in at least two of the first three questionnaires during the initial phase of treatment showed significantly reduced overall survival. Conclusions: Early and repeated QoL assessments, particularly within the first weeks of therapy, offer critical prognostic value in advanced rectal cancer. Identifying patients with an unfavourable prognosis might allow faster interventions that could improve survival outcomes. Integrating QoL monitoring into routine clinical practice could enhance individualised care and support risk stratification.
