Self-directed physical activity intervention in older adults undergoing adjuvant chemotherapy for colorectal cancer: Design of a randomized controlled trial

Evaluation of adverse events and health-related quality of life in patients with colorectal cancer receiving ambulatory home-based chemotherapy in Thailand

Aims

To compare adverse events and health‐related quality of life in ambulatory home‐based chemotherapy with those in inpatient.

Design

Prospective non‐randomized observational study.

Methods

Participants were divided into two groups according to patients’ preference receiving chemotherapy.

Results

Sixty‐four participants were enrolled in the inpatient, and 111 were in an ambulatory home‐based chemotherapy. The frequency of anaemia, neutropenia and thrombocytopenia was significantly higher in inpatient group than in ambulatory home‐based chemotherapy group (p < .001, <.001 and .002, respectively). Nausea, mucositis, and fatigue were more common in ambulatory home‐based chemotherapy group than in inpatient group (p < .001, .022, and .005, respectively). Patients in the ambulatory home‐based chemotherapy group showed higher social well‐being (SWB) scores than inpatient group (coefficient 1.92, 95% confidence interval [CI] 0.65 to 3.19, p .003).

The physical activity of colorectal cancer survivors during chemotherapy : Based on the theory of planned behavior

PURPOSE

The purpose of this study was to investigate the physical activity (PA) of colorectal cancer (CRC) survivors during chemotherapy and to explain it based on the theory of planned behavior (TPB). In addition, the effects of planning, past physical activity (P-PA), and self-efficacy on the PA of CRC survivors were analyzed.

METHODS

CRC survivors were recruited in a third-grade hospital of Changchun via a convenience sampling method. All survivors were asked to complete self-report questionnaires assessing medical and demographic variables, PA, constructs from the TPB, P-PA, planning, and self-efficacy.

RESULTS

A total of 174 CRC survivors were included in this study. Only 7.5% (13) of these CRC survivors had sufficient PA, and 32.2% (56) of CRC survivors were completely sedentary. Gender, education level, working status, residential location, method of payment for medical expenses, and cancer stage were all associated with PA in these patients (P < 0.05). The path model was able to explain 54% (R² = 0.54) of the PA variance in these CRC survivors. P-PA had the greatest impact on PA during chemotherapy, and P-PA affected PA both directly and indirectly through planning.

CONCLUSIONS

Insufficient PA in CRC survivors was associated with a variety of factors, with P-PA having the greatest impact on this outcome. The results of this study suggest that attention must be paid to survivors who had exhibited insufficient PA prior to initial diagnosis.

Dihydroartemisinin increases apoptosis of colon cancer cells through targeting Janus kinase 2/signal transducer and activator of transcription 3 signaling

As a derivative of artemisinin, dihydroartemisinin is effective in the treatment of malaria. Dihydroartemisinin has been identified to possess inhibitory effects in numerous types of animal model with tumors, indicating that it has an antineoplastic effect. The aim of the present study was to analyze the potential anticancer effects of dihydroartemisinin, particularly its effect on apoptosis of colon cancer cells. In the present study, it was identified that dihydroartemisinin inhibited cell viability, promoted cell apoptosis, increased B-cell lymphoma-2-associated X-protein expression, increased caspase-3/9 activities, decreased poly(ADP-ribose) polymerase levels, decreased phosphorylation of extracellular-signal-regulated kinase, and increased phosphorylation of c-Jun N-terminal kinase and p38 mitogen-activated protein kinase in colon cancer cells. Conversely, the phosphorylation of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) was suppressed by dihydroartemisinin in colon cancer cells. These results demonstrate that the potential anticancer effects of dihydroartemisinin may increase apoptosis of colon cancer cells through targeting JAK2/STAT3 signaling.
