Autocrine and paracrine growth mediated by the platelet-derived growth factor (PDGF)/PDGF receptor (PDGFR)-signaling pathway plays an important role in the progression of solid tumors. The authors assessed the effect of STI571 on the tumor growth of gastric carcinoma in combination with 5-fluorouracil (5-FU) or paclitaxel targeting the PDGF/PDGFR-signaling pathway. ⋯ STI571 was an effective chemosensitizer of antitumor drugs, such as 5-FU and paclitaxel for gastric carcinoma, targeting the PDGF/PDGFR-signaling pathway of tumor cells and stromal cells in disease progression and angiogenesis.

It is challenging for clinicians to foster coping and allow hope when discussing prognosis and end-of-life (EOL) issues with terminally ill cancer patients and their caregivers. To the authors' knowledge, little research evidence is currently available to guide clinical practice. ⋯ The results of the current study demonstrated that most participants believed there were ways of fostering coping and maintaining hope and that HPs have a role in facilitating this with terminally ill cancer patients and their caregivers.

The difficulty of negotiating the concerns of family members while also respecting the needs of the patient adds complexity to the task of discussing prognosis and end-of-life (EOL) issues with terminally ill cancer patients. The informational needs of caregivers may be different from those of the patients themselves with regard to these topics. However, to the authors' knowledge, this issue has received relatively little research attention. ⋯ The results of the current study emphasized the importance of considering the distinct informational needs of caregivers, as well as those of the patient, when discussing prognosis and EOL issues.
