Edward Yang, best director winner at the 2000 Cannes Film Festival, died Friday at his Beverly Hills home from complications of colon cancer. He had been battling the disease for seven years but kept his condition private. He was 59.

Yang, an American citizen born in Shanghai, first made a career for himself as a computer engineer. On his 30th birthday, he decided to change directions. He became a filmmaker.

Known for his realistic movie portrayals of modern Taiwan, Yang favored stories set in the Taiwanese capital, Taipei. He is responsible for the 1991 film A Brighter Summer Day. First-time actor Chang Chen worked on this film and then went on to star in Crouching Tiger, Hidden Dragon, the Ang Lee kung fu hit.

The lung cancer drug Gefitinib has been taken off shelves in the United States due to ineffectiveness. But it remains effective in some Taiwanese lung cancer patients, according to a study published in the journal Lung Cancer.

The study, conducted by the National Health Research Institutes, involved 65 non-small-cell lung cancer patients and found that more than 50 percent of participants responded to the drug therapy -- while only 10 percent respond in Western studies.

A genetic mutation of the epidermal growth factor receptor (EGFR) was found in most patients who responded to Gefitinib. The mutation is rare in Western countries but much more common in East Asian countries where the mutation increases the likelihood of developing adenocarcinoma.

About 6,800 Taiwanese patients develop non-small-cell lung cancer every year. Of these, 65 percent of cases are adenocarcinoma. Of this group, 57 percent will have the genetic mutation. And roughly half will respond to Gefitinib.

I think it's safe to say that a large amount of women in this world lack self confidence. Tack on a few incisions and scars, some lop-sided or altogether missing breasts, a handful of scattered blue tattoos, a head full of newly sprouting hair, swelling arms, drug-damaged fingernails and toenails, damaged veins, alien-like ports protruding from underneath skin, unpredictable hot flashes, and a foggy brain and it's clear that women surviving breast cancer may have a few of their own issues concerning self confidence. It doesn't take science to prove this reality -- although there are studies out there that do confirm and validate that breast cancer survivors struggle with positive self images.

Results of a study released Wednesday reveal that the vast majority of breast cancer patients in Taiwan lose self confidence after having their breasts removed. The study shows that 90 percent of participants feel they have lost their beauty and femininity following a mastectomy. Women worry about their partner's perception of them after such radical appearance changes. They doubt their roles in their workplace and families. They are even afraid of having sex with their partners. And if the patients' relationship with their spouses are not good in the first place, breast removal surgery will lead to divorce about 10 percent of the time.

There is no doubt that female roles vary from country to country -- and what studies show in Taiwan may not be completely applicable to women in the United States. But there is one universal truth that knows no boundaries -- all women recovering from the ravages of breast cancer will encounter struggles. Because breast cancer does not discriminate when it comes to compromising the self esteem of its targets.

Stomach cancer is hard to detect. It has no symptoms in its early stages, and there is no effective screening to detect its presence. So early detection and early treatment for this disease -- that attacks 800,000 people worldwide -- are hard to come by. In Taiwan, stomach cancer is the fifth most common cancer and the focus of study for researchers working to devise a method for detecting stomach cancer in its infancy.

A team of researchers at National Taiwan University Hospital have discovered a toxic factor -- GroES -- that causes stomach cancer. And they have discovered that a simple blood test will show either a positive or negative result for this substance, leading to immediate endoscopic exams for patients who may be at risk for stomach cancer. The test to identify GroES has already achieved a 65 percent accuracy rate.

Apparently, if the human body is infected with GroES, it produces antibodies to the factor and can cause chronic inflammation of the stomach, causing cells to rupture and proliferate. Long-term inflammation can cause stomach cancer. Researchers say about 45 percent of adults in Taiwan are infected with GroES -- and one percent will go on to develop stomach cancer.

Right now, patent applications are underway in the United States, Japan, and Taiwan. Once a kit is developed, a single drop of blood will be all it takes to determine the risk for stomach cancer.

Chemotherapy is a good remedy for killing cancer cells -- and I hope every day that it did its job and killed all cancer cells that may have floated away from my original breast cancer tumor. But one not-so-good side effect of this good remedy is the beating that healthy cells take in the process of this life-saving treatment. It will be a red-letter day when chemotherapy can target only cancer cells, while leaving healthy cells unaffected. And this day may be a bit closer for patients in Taiwan who find they are in the early stages of relapse with nasopharynx cancer.

On Wednesday, National Taiwan University Hospital introduced a new high-tech laser procedure -- potassium-titanyl-phosphate or KPT -- to vaporize cancer cells. Doctors use a small endoscopic camera and easily manipulate the laser to precisely eliminate the cancer cells in the back of the nose and the soft roof of the mouth -- without harming healthy cells. The procedure takes roughly 90 minutes and requires a two-day stay in the hospital. This procedure should only be used in the early stages of relapse, though, and first-time cancer patients should still seek chemotherapy. And while those in later stages of relapse can still receive the treatment, it will only relieve discomfort without solving the problem.

To date, there have been 16 successful KPT treatments for this disease that about 1,000 people in Taiwan contract each year.
