“…Future investigations might examine whether such diet-induced improvements in physical function might reduce morbidity and mortality. Although the MCS did not differ significantly between the two diet groups, scores in both groups were comparable if not higher than those observed in other samples of cancer patients as well as healthy cancer-free adults [ 19 , 22 , 33 , 34 ]. Thus, an increase in MCS may have been difficult to achieve due to a ceiling effect.…”

“…Responses to the questionnaire’s 12 items are scored to produce a physical component summary and a mental component summary on a scale from 0 to 100, with higher scores indicative of better functional status. The SF-12 is well validated and has been used in over 600 clinical trials in people with a variety of illnesses and health conditions, including cancer [ 21 , 22 ].…”

Favorable Effects of a Ketogenic Diet on Physical Function, Perceived Energy, and Food Cravings in Women with Ovarian or Endometrial Cancer: A Randomized, Controlled Trial

Ketogenic diets (KDs) are gaining attention as a potential adjuvant therapy for cancer, but data are limited for KDs’ effects on quality of life. We hypothesized that the KD would (1) improve mental and physical function, including energy levels, (2) reduce hunger, and (3) diminish sweet and starchy food cravings in women with ovarian or endometrial cancer. Participants were randomized to a KD (70:25:5 energy from fat, protein, and carbohydrate) or the American Cancer Society diet (ACS: high-fiber, lower-fat). Questionnaires were administered at baseline and after 12 weeks on the assigned diet to assess changes in mental and physical health, perceived energy, appetite, and food cravings. We assessed both between-group differences and within-group changes using ANCOVA and paired t-tests, respectively. After 12 weeks, there was a significant between-group difference in adjusted physical function scores (p < 0.05), and KD participants not receiving chemotherapy reported a significant within-group reduction in fatigue (p < 0.05). There were no significant between-group differences in mental function, hunger, or appetite. There was a significant between-group difference in adjusted cravings for starchy foods and fast food fats at 12 weeks (p < 0.05 for both), with the KD group demonstrating less frequent cravings than the ACS. In conclusion, in women with ovarian or endometrial cancer, a KD does not negatively affect quality of life and in fact may improve physical function, increase energy, and diminish specific food cravings. This trial was registered at as NCT03171506.

The aim of this study was to evaluate the clinical diagnostic value of combined detection of serum ferritin (SF), carcino-embryonic antigen (CEA) and C-reactive protein (CRP) in non-small cell lung cancer (NSCLC). Methods: The study included 70 patients with NSCLC, 50 patients with benign lung disease and 50 healthy subjects. The serum concentrations of SF, CEA and CRP were determined by ELISA. Results: The results showed that the serum levels of SF, CEA and CRP in the NSCLC group were significantly higher than those of the benign lung disease group and the control group. The expression of the above three indexes in the lung cancer group III+IV was higher than that in the I+II group (P<0.05), and the expression of SF, CEA and CRP in the adenocarcinoma group was higher than that in the squamous cell carcinoma group. The difference is statistically significant (P<0.01). When the serum CEA, SF and CRP levels were used alone for diagnosis of NSCLC, CRP had the best diagnostic value. The area under the curve was 0.795. The diagnostic sensitivity and specificity were 81.8% and 66.8%, respectivelyWhen combining these three factors, the area under the curve was 0.890, and the sensitivity and specificity were 80.3% and 82.5%, respectively. The parameters above were also significantly different (all P<0.01). Conclusion: This study indicated that the combined detection of serum SF, CEA and CRP could improve the early diagnostic sensitivity of NSCLC, and may be used as a potential diagnostic method for NSCLC.

“…A higher score corresponds to better physical HRQOL and mental HRQOL scales. The scale has good construct validity, convergent validity, discriminant validity and reliability (Bhandari, Kathe, Hayes, & Payakachat, 2018;Shou et al, 2016;Ware et al, 1996). The internal consistency value (Cronbach's α) for the total scale was 0.91, for the PCS, 0.89; and, for the MCS, 0.88 (Bhandari et al, 2018;Shou et al, 2016).…”
