Fentanyl is used as an analgesic to treat pain in a variety of patients with cancer. Moreover, fentanyl may affect tumor growth in many cell lines. To gain better insight into the interaction between fentanyl and tumor, we investigated the effects of fentanyl on the growth of gastric carcinoma cells and the expression of some apoptosis-related genes including NF-kappaB and PTEN. A human gastric cancer cell line MGC-803 was used. The viability and proliferation of gastric cancer MGC-803 cells were detected by MTT assay and colony formation assay. The cell cycle progression and apoptosis were assessed by flow cytometry and the ultrastructure of cells was examined with transmission electron microscope. The migration of cells was investigated by wound healing assay. The expression of NF-kappaB and PTEN was evaluated by semiquantitative RT-PCR and Western blot. Our data showed that fentanyl could inhibit cell growth and proliferation and made cell cycle arrest at G2/M phase. Compared with control cells, MGC-803 cells that were incubated with fentanyl also had a higher apoptotic rate. Fentanyl could lead to morphological changes of gastric cancer cells and reduce the motility of MGC-803 cells. Moreover, fentanyl could downregulate NF-kappaB and upregulate PTEN, which might be the mechanism of fentanyl inhibiting gastric cancer progression in vitro.

Akathisia is a condition wherein sitting calmly and quietly is impossible, with a representative complaint of restless legs. It is generally assumed to be caused by anti-dopamine activity. In severe cases, it has been known to result in suicide attempt. We reported a case of drug-induced akathisia with difficulty in oral intake, in which fentanyl citrate sublingual tablets were found to be effective in relieving symptoms. The patient was a female aged 50's who had a gastric cancer with peritoneal dissemination causing pain and vomiting. Palliative care was requested for management of symptoms. Metoclopramide and haloperidol were administered for vomiting. However, because of the complaints of restless legs, the case was diagnosed as drug-induced akathisia. Fentanyl citrate sublingual tablets were then administered for pain management, resulting in temporary improvement of akathisia symptoms.

Cancer patients often suffer from severe pain related to bone metastasis. We encountered a patient in whom the addition of topical non-steroidal anti-inflammatory drugs (NSAIDs) for persistent pain related to bone metastasis during therapy with opioids and oral NSAIDs reduced pain, improving activities of daily living (ADL). Fentanyl patches, celecoxib, denosumab, and topical NSAIDs (loxoprofen tape, felbinac) were administered to a 72-year-old patient with gastric cancer and pain related to bone metastasis. Pain control was favorable, with a numerical rating scale (NRS) score of 2 and Japanese version Support Team Assessment Schedule (STAS-J) score of 1. Intervention by pharmacists for the use of topical NSAIDs decreased both the NRS and STAS-J scores to zero, improving ADL. The results suggest that topical NSAIDs relieve bone-metastasis-related pain, improving ADL. When bone-metastasis-related pain is localized, the prescription of topical NSAIDs should be considered, and positive intervention by pharmacists regarding their usage should be promoted.
