Surgery can reduce the chance of death from lung cancer by a third, lung specialist Dr Manoon Leechawengwongs said on Monday.
He was citing the case of an 84-year-old man who was treated for third-stage lung cancer in 2019.
Dr Manoon explained that the patient had stopped smoking for 35 years, but still had high blood pressure and higher than normal carcinoembryonic antigen level.
“We decided to cut the patient’s lower left lung and lymph nodes in the chest cavity after a 5-centimetre tumour was found,” he said, adding that the tumour was a poorly differentiated nonkeratinizing squamous cell cancer.
He said cancer had spread to lymph nodes near the tumour but not to lymph nodes in the chest cavity.
“After the surgery, the patient recovered gradually without having to rely on chemotherapy or radiation,” he said, adding that the patient is healthy three years later.
Lung cancer, or lung carcinoma, usually involves a malignant tumour characterised by uncontrolled cell growth in the lung tissues.
Up to 85 per cent of the cases of lung cancer are due to long-term smoking, though 10-15 per cent of cases have occurred in persons who have never smoked.
These cases are often caused by a combination of genetic factors, exposure to radon gas, asbestos, second-hand smoke or other forms of air pollution.
In 2020, lung cancer was diagnosed in 2.2 million people across the world, resulting in 1.8 million deaths. It is the most common cancer among both men and women.
Type A influenza is rearing its head again after having disappeared for two years, a lung specialist warned on Friday.
In a Facebook post, Dr Manoon Leechawengwongs warned people to beware of the virus as their immunity may have dropped over the past two years. This is because there were no infections and most people will not have taken their annual flu vaccine.
Hence, he said, people in the high-risk group, namely the elderly, people with underlying diseases, small children and pregnant women should get their flu shots as soon as possible.
He also said that both Covid-19 and Type A influenza have similar symptoms, namely fever, coughing, sore throat and runny nose. Thus, he said, people with these symptoms should be tested for both Covid-19 and influenza and take relevant drugs immediately.
Dr Manoon cited the case of a 75-year-old patient who suffers from hypertension and hyperlipidaemia. She visited a doctor on Wednesday, complaining of high fever, phlegm, sore throat, dizziness and nausea for four days. She said she had been with her three grandchildren, who all caught the flu from May 14 onwards.
The patient had no fever when she visited the doctor, and her oxygen levels and chest X-ray were normal. She tested positive for Type A influenza but not Covid-19 and was prescribed the relevant medication.
Dr Manoon added that another family had been hit by Type A influenza at around the same time.
Monkeypox will continue spreading among humans for a while, the National Centre for Genetic Engineering and Biotechnology director Dr Anan Jongkaewwattana said on Thursday in response to new cases being detected in Europe and Canada.
Meanwhile, leading virologist Dr Yong Poovorawan said on Friday that monkeypox can only be transmitted through close contact, adding that a case was also detected in Singapore recently. As for the monkeypox case in Britain, he said the authorities are still checking to see if it was transmitted through sexual intercourse.
The first human case of monkeypox, a viral zoonotic disease, was recorded in 1970 in the Democratic Republic of Congo. It has since been found primarily in Central and West Africa, and occasionally in other parts of the world.
The symptoms typically are fever, rash and swollen lymph nodes, and may lead to a range of medical complications.
Dr Anan said the monkeypox variant found in Africa is far more severe than the one currently infecting people in Europe and Canada. He added that the virus comes from the same family as smallpox, which was eradicated by 1980 thanks to widespread vaccination.
When monkeypox was first detected in 1958 among monkeys kept for research, “it was not a big issue because many people had been vaccinated against smallpox”. He said that though the smallpox vaccine can effectively prevent monkeypox infection, “it may spread among humans again as it has been a long time since people have been jabbed against smallpox”.
Separately, Dr Yong supported Dr Anan’s belief that smallpox vaccines can prevent monkeypox, but also urged Thais not to worry about this issue as monkeypox has not been found in Thailand before.
However, he said, surveillance is necessary, especially among travellers from Central and West Africa as well as imported animals.

Covid-19 will soon be declared endemic in Thailand, leading virologist Dr Yong Poovorawan announced on Tuesday.
In a Facebook post, he pointed out that the number of Covid-19 infections in the country is declining and very soon this virus will become endemic like influenza.
For instance, he said, influenza spread widely in 2009 before becoming endemic in 2010. Influenza still exists and there is a regular outbreak, especially during the rainy season from May to September, he said.
Hence, Dr Yong said students should be given their flu shots now that schools have reopened and the rains have started.
He also said that if it becomes necessary to administer Covid-19 vaccines every year, jabs should be given before schools open.
Thailand has been advised to consider quarantining travellers from South Africa and Portugal after recent reports show that the more infectious BA.4 and BA.5 Omicron subvariants are fast spreading there.
The European Centre for Disease Prevention and Control (ECDC) recently named BA.4 and BA.5 as variants of concern.
Public Health Commission vice-chairman Chalermchai Boonyaleephan said on Monday that the Omicron BA.2 subvariant is the dominant strain in many countries, including Thailand.
However, both BA.4 and BA.5 that have been found in South Africa spread faster than the BA.1 subvariant and can infect people despite them being vaccinated or being infected with Covid-19 earlier.
He also predicted that the BA.5 subvariant will become the dominant strain in Portugal by Sunday (May 22) as 37 per cent of the population is already infected with the BA.5 subvariant.
“Thailand should consider quarantining tourists from Portugal and South Africa or at least having them undergo RT-PCR tests to prevent these subvariants from entering the country,” he said.
He added that ECDC has warned European countries to beware of these subvariants and has advised both countries to give the elderly and people with chronic diseases a fourth jab.
“The World Health Organisation, however, has not named BA.4 and BA.5 as variants of concern yet,” he added.
Separately, leading virologist Dr Yong Poovorawan said an mRNA booster for people whose first two jabs are inactivated vaccines helps boost immunity against Covid-19 effectively.
“The immunity provided by a Pfizer booster after receiving two Sinovac or Sinopharm jabs is similar to three Pfizer jabs,” he said, citing a study conducted by Chulalongkorn University’s Centre of Excellence in Clinical Virology, which he heads. He added that this combination should also provide high immunity to children.
The national drug system development committee included antiviral drugs for hepatitis B and C, both of which could trigger liver cancer, on the National List of Essential Medicines on Wednesday.
Food and Drug Administration deputy secretary-general Surachoke Tangwiwat said 916 drugs are mentioned on the list.
He said the move aimed to enable more people to access hepatitis B and C antiviral drugs as both diseases could trigger liver cancer.
The price of hepatitis C antiviral drugs will become cheaper as the Government Pharmaceutical Organisation is now able to produce them, he noted.
“Patients who have hepatitis B will receive new drugs which can treat the virus effectively,” he said.
Surachoke added that the rising median price of some drugs has been “improved” to facilitate procurement and enable more people to access the drugs, such as granulocyte colony-stimulating factor, a glycoprotein that stimulates bone marrow.
On Wednesday, the National Communicable Disease Committee approved a strategy to eliminate hepatitis B and C between 2022 and 2030 as these diseases are considered a global public health problem.
Separately, expert virologist Dr Yong Poovorawan pointed out on his Facebook page on Thursday that the number of children with chronic hepatitis has increased in more than 20 countries.
Almost one out of every five young children in Thailand has already been infected with Covid-19, a leading virologist said on Monday.
Dr Yong Poovorawan said about 8 per cent of children aged 5-6 were infected during the Delta outbreak, citing an infection survey conducted by Chulalongkorn University’s Centre of Excellence in Clinical Virology, which he heads.
“The infection among this group of children increased to 17 per cent during the Omicron outbreak,” he said in a Facebook post on Monday.
“More than half of them were asymptomatic,” Yong added, explaining that their previous infection was shown by the presence of Covid-19 virus antibodies in their blood.
He said that 8 per cent of children aged 6-11 years who participated in the centre’s research study had also shown previous infection with asymptomatic Covid-19.
“This proves that small children may have already been infected with Covid-19 and these infections are likely to increase.”
However, most of them were asymptomatic and will have generated immunity against the virus in future, Yong added.
He believes many teenagers and adults have already been infected with Covid-19 unknowingly after experiencing no or only mild symptoms.
However, this should help create herd immunity and reduce the virus’s severity in the future.
Meanwhile, the Chula centre’s Covid-19 infection survey was a useful tool for making disease-control plans, he said.
