※ 引述《sun8 (popo)》之銘言：
: 今天在BBC 看了底下的新聞，不過是英文的。
: 大致上好像是說高劑量的維他命C用靜脈注射可以有效抗癌，
: 但是因為好像難從專利上獲利，所以這方面研究沒那麼吸引人進入。
: 有人可以翻譯一下嗎? 我的英文沒很好，怕有誤解

: High-dose vitamin C can boost the cancer-killing effect of chemotherapy in
: the lab and mice, research suggests.
: Given by injection, it could potentially be a safe, effective and low-cost
: treatment for ovarian and other cancers, say US scientists.
: Reporting in Science Translational Medicine, they call for large-scale

: Pharmaceutical companies are unlikely to run trials, as vitamins cannot be

: Vitamin C has long been used as an alternative therapy for cancer.
: In the 1970s, chemist Linus Pauling reported that vitamin C given

: However, clinical trials of vitamin C given by mouth failed to replicate the
: effect, and research was abandoned.
: It is now known that the human body quickly excretes vitamin C when it is
: taken by mouth.
: However, scientists at the University of Kansas say that when given by
: injection vitamin C is absorbed into the body, and can kill cancer cells
: without harming normal ones.
: The researchers injected vitamin C into human ovarian cancer cells in the
: lab, into mice, and into patients with advanced ovarian cancer.
: They found ovarian cancer cells were sensitive to vitamin C treatment, but
: normal cells were unharmed.
: The treatment worked in tandem with standard chemotherapy drugs to slow
: tumour growth in mouse studies. Meanwhile, a small group of patients reported
: fewer side-effects when given vitamin C alongside chemotherapy.
: No patent potential
: Co-researcher Dr Jeanne Drisko said there was growing interest in the use of
: vitamin C by oncologists.
: "Patients are looking for safe and low-cost choices in their management of
: cancer," she told BBC News. "Intravenous vitamin C has that potential based
: on our basic science research and early clinical data."
: One potential hurdle is that pharmaceutical companies are unlikely to fund
: trials of intravenous vitamin C because there is no ability to patent natural
: products.
: "Because vitamin C has no patent potential, its development will not be
: supported by pharmaceutical companies," said lead researcher Qi Chen.
: "We believe that the time has arrived for research agencies to vigorously
: support thoughtful and meticulous clinical trials with intravenous vitamin C."
: Dr Kat Arney, science communications manager for Cancer Research UK, said
: there was a long history of research into vitamin C for treating cancer.
: "It's difficult to tell with such a small trial - just 22 patients - whether
: high-dose vitamin C injections had any effect on survival, but it's
: interesting that it seemed to reduce the side-effects of chemotherapy," she
: said.
: "Any potential treatment for cancer needs to be thoroughly evaluated in large
: clinical trials to make sure it's safe and effective, so further studies are
: needed before we know for sure what benefits high dose vitamin C may have for
: patients."
