          Abstract

          This retrospective study investigated the effectiveness of percutaneous nerve electrical stimulation (PNES) for fatigue caused by chemotherapy for cervical cancer survivors.

          Totally, 83 cases of fatigue caused by chemotherapy for cervical cancer survivors were analyzed. All these cases were assigned to a treatment group (n = 43), and a control group (n = 40). Patients in the treatment group received PNES, while the subjects in the control group were on waiting list. The treatment was applied once daily for a total of 6 weeks. The primary endpoint was fatigue. It was evaluated by the Multidimensional Fatigue Inventory (MFI), and Fatigue Questionnaire (FQ). The secondary endpoints consisted of anxiety and depression. They were measured by the Hospital Anxiety and Depression Scale (HADS). All outcomes were measured before and after 6-week treatment.

          After treatment, PNES did not show significant difference in fatigue relief, measured by MFI (General fatigue, P = .31; Physical fatigue, P = .44; Activity, P = .36; Motivation, P = .55; Mental fatigue, P = .49), and FQ (Mental fatigue, P = .29; Physical fatigue, P = .35); and the reduction of anxiety and depression, measured by the HADS (Anxiety, P = .21; Depression, P = .17) after 6 weeks treatment between 2 groups.

          This study demonstrated that PNES may not benefit for cervical cancer survivors with fatigue caused by chemotherapy after 6-week treatment.

          Cohort Studies: Prospective versus Retrospective

          Cohort studies form a suitable study design to assess associations between multiple exposures on the one hand and multiple outcomes on the other hand. They are especially appropriate to study rare exposures or exposures for which randomization is not possible for practical or ethical reasons. Prospective and retrospective cohort studies have higher accuracy and higher efficiency as their respective main advantages. In addition to possible confounding by indication, cohort studies may suffer from selection bias. Confounding and bias should be prevented whenever possible, but still can exert unknown effects in unknown directions. If one is aware of this, cohort studies can form a potent study design in nephrology producing, in general, highly generalizable results.

            Cancer-related fatigue: a systematic and meta-analytic review of non-pharmacological therapies for cancer patients.

            Cancer-related fatigue (CRF) is a significant clinical problem for more than 10 million adults diagnosed with cancer each year worldwide. No "gold standard" treatment presently exists for CRF. To provide a guide for future research to improve the treatment of CRF, the authors conducted the most comprehensive combined systematic and meta-analytic review of the literature to date on non-pharmacological (psychosocial and exercise) interventions to ameliorate CRF and associated symptoms (vigor/vitality) in adults with cancer, based on 119 randomized controlled trials (RCTs) and non-RCT studies. Meta-analyses conducted on 57 RCTs indicated that exercise and psychological interventions provided reductions in CRF, with no significant differences between these 2 major types of interventions considered as a whole. Specifically, multimodal exercise and walking programs, restorative approaches, supportive-expressive, and cognitive-behavioral psychosocial interventions show promising potential for ameliorating CRF. The results also suggest that vigor and vitality are distinct phenomena from CRF with regard to responsiveness to intervention. With improved methodological approaches, further research in this area may soon provide clinicians with effective strategies for reducing CRF and enhancing the lives of millions of cancer patients and survivors.

              Side-effects of chemotherapy and quality of life in ovarian and breast cancer patients.

              Women diagnosed with ovarian cancer or breast cancer often face aggressive chemotherapy involving multiple treatment regimens. These treatments may be associated with significant side-effects that adversely impact patient quality of life. In this review, we will highlight recent research on side-effects of chemotherapy and the quality-of-life concerns of women with ovarian and breast cancer. Adjuvant chemotherapy has demonstrated efficacy in the management of ovarian and breast cancers. In addition to physical side-effects, a subset of women receiving chemotherapy will experience significant cognitive dysfunction that adversely affects their perceived quality of life. Variables including disease response, treatment indication and extent of the patient's social support also influence quality-of-life ratings. Although prolongation of survival remains the primary goal of chemotherapy, the palliation of symptoms and preservation of quality of life are also important treatment considerations. Chemotherapy may be associated with nausea, vomiting, hair loss, cognitive dysfunction, fatigue, changes in sexual functioning and reductions in quality-of-life ratings. Although rare to date, prospective, randomized, longitudinal studies that incorporate a pre-treatment assessment of symptom burden and perceived quality of life are necessary to define the severity and pattern of treatment-related change and subsequently guide intervention strategies. In some cases, quality-of-life issues may help to guide patient-care decisions.
