Background: Measuring effects of cancer on family caregivers is important to develop methods which can improve their quality of life (QOL). Nevertheless, up to now, only a few tools have been developed to be used in this group. Among those, the Caregiver Quality of Life Index-Cancer Scale (CQOLC) has met minimum psychometric criteria in different populations in spite of conflicting results. The present study was conducted to evaluate reliability and validity of CQOLC among Turkish cancer family caregivers. Materials and Methods: The CQOLC was administered to 120 caregivers, along with Beck Depression Inventory (BDI), Medical Outcome . . .s Study MOS 36- Item Short Form Health Survey (SF-36), State-Trait Anxiety Inventory (STAI), and Multidimensional Scale of Perceived Social Support (MSPSS). Internal consistency and test-retest stability were used to investigate reliability. Construct validity was examined by using known group method, convergent, and divergent validity. For the known group method, we hypothesized that CQOLC scores would differ between depressed and non-depressed subjects. We investigated convergent validity by correlating scores for CQOLC with scores for other similar measures including SF-36 and STAI. The MSPSS was completed at the same time as CQOLC to provide divergent validity. Results: The values for internal consistency and test-retest correlation were 0.88 and 0.96, respectively. The CQOLC discriminated those who were depressed from those who were not. Convergent validity supported strong correlations between CQOLC scores and two main component scores (PCS, MCS) in SF-36 although there was a weak correlation between CQOLC and STAI scores. Regarding divergent validity, the correlation between CQOLC and MSPSS was in the low range, as expected. Conclusions: The Turkish CQOLC is a reliable and valid tool and it can be utilized to determine QOL of family caregivers
Background: Effects of whole cell type immunization on mice Ehrlich tumours were evaluated. Materials and Methods: After preliminary study, mice were divided two major groups; 1x1000 and 100x1000 live Ehrlich cell transferred major groups, each divided into four subgroups (n: 10). Study groups were immunized with Ehrlich cell lysates in 0, 3, 7, 14th days and after 30 days of last immunization, live Ehrlich cells were transferred. Mice were observed for six months and evaluated for total and cancer free days. Results: Out of 100x1000 cell transferred solid type study group, all study group mean and tumour free periods were statistic . . .ally longer than control groups. All 1x1000 Ehrlich cell transferred study groups survived significantly longer than 100x1000 Ehrlich cell transferred groups. Conclusions: Ehrlich mice tumours were prevented and survival prolonged with whole cell type immunization. Effects are related to the number of transferred tumor cells
