Are COVID-19 vaccines safe in cancer patients having immunotherapy?

Yes, Pfizer vaccine is safe.

A recent study published in the esteemed Lancet Oncology Journal shows that the vaccine is well tolerated in patients having immunotherapy.

Unlike cancer chemotherapy, immunotherapy works differently. It works by releasing the in-built brakes holding down the immune system thereby boosting the body’s immune system against cancer.

There has been some theoretical concerns whether this might lead to COVID vaccine causing more side effects.

Reassuringly, the Vaccine side effects were NO different from those seen in people not having immunotherapy. The Vaccine also did NOT increase the immunotherapy side effects.

Immunotherapy is increasingly used widely in treatment of cancer are often better tolerated than chemotherapy.

So the study is good news for tens of thousands of patients on immunotherapy and any cancer patient who has hesitated before, should seriously consider having the vaccine now

COVID infection could be very nasty in cancer patients and all evidence points to the benefits of vaccine far outweighing any risks from the Vaccine.

Does smoking cause Body pain ?

Yes. Smoking can cause body pain and make you miserable.

Smoking is bad for various obvious reasons including the risk of developing of cancer. As smoking can make you miserable with pain, it’s time to make a new year resolution to stop smoking.

A large study done in UK shows that current and ex-smokers have a higher degree of bodily pain.

The study involved 223,537 people who were surveyed between 2009 and 2013 by the British Broadcasting Corporation (BBC) Lab UK Study.

As it is such a big study, the conclusions do need to be taken seriously.

Definitely another reason for quitting smoking this new year !

Is the COVID-19 Coronavirus vaccine safe for use in patients having chemotherapy and immunotherapy?

Yes, the available indirect evidence indicates that the anticipated benefits overweigh the potential risks.

Cancer patients, particularly those on chemotherapy have compromised immune systems and hence more vulnerable to COVID-19 Coronavirus complications.

The guidelines indicate that anticipated benefits of vaccine are greater than unknown risks from the Coronavirus vaccines.

The Vaccine trials deliberately included lot of healthy people. Very few people with cancer, particularly cancer patients on active treatment, were included in the COVID-19 trials. So there is not much direct evidence regarding efficacy and safety of Vaccines in cancer patients. But indirect evidence significantly favours Coronavirus vaccination in cancer patients.

Flu vaccines are regularly used in cancer patients without any major side effects specific to cancer patients. No increase in incidence or severity of drug side effects were seen in immunotherapy patients having flu vaccines.

On balance, Vaccination is most likely to be of utmost benefit for most advanced cancer patients on active treatment.

Is it worth stopping smoking after a diagnosis of lung cancer ?

Yes.

It is not too late to stop smoking even after a diagnosis of lung cancer.

A Study presented at the American Society of Clinical Oncology meeting earlier this year reports that ” No matter when smokers quit, their chance of survival increases following a lung cancer diagnosis”.

A highly effective treatment for secondary brain cancer in some Lung cancer patients

Brain secondaries from many primary cancer is always difficult to treat.

Particularly brain secondaries from Lung cancer patients can be quite difficult to treat.

Whole Brain Radiotherpy was widely used in past to treat brain secondaries in Lung cancer patients until 2016.

In 2016, QUARTZ study reported that Radiotherapy provided“ little additional clinically significant benefit for this patient group”.

So very few treatment options existed for this group of patients.

So it’s reassuring to see that a new drug was found to be highly active in lung cancer patients with brain secondaries.

Data presented at ESMO ( European Society of Medical Oncology) shows that the Lorlatinib showed a staggering 82% response rate in a small sub-group of patients.
