Low Bacterial Diet and Chemotherapy

What is the evidence of low bacterial diet in patients with chemotherapy for solid tumours? I could not really find anything conclusive in the data available.

Can someone help me out here.

Most of the data is anecdotal about a patient getting this illness or that illness, but the majority of the patients get along fine with clean, cooked food. This concept of scaring patients and their families into only eat this or that and avoid this and that…. it a complete overkill.

Now patients undergoing a bone marrow transplant with sustained neutropenia… that is a completely different story. I am talking only about patients with solid tumours undergoing chemotherapy. The period of neutropenia is relatively short and patients bouncy back fairly soon.

Eat well. Stay strong and healthy.

Australian Medicine

Medicine in Australia is top class. It may not be as cutting edge as some hospitals in the US or Western Europe, but for all practical purposes… medicine in Australia is fantastic.

There is a talk about dearth of the latest molecules, but in terms of being pragmatic and the true value for the dollar… there is almost everything available. When I talk about being available, I am talking about being funded by the government (which means free to the patient). Everything, which is not funded by the government, is available on the market (for a price).

The quality of care even in remote towns is great. If a facility is not available or there is a emergency, the Royal Flying Doctors help out.

Adjuvant Herceptin / Trastuzumab Treatment Duration

A few years ago when Herceptin (trastuzumab) was launched for the early stage of Her2+ breast cancer, the timing of treatment was fixed at one year. Why one year? No clue. Just a consensus figure decided by a few oncology investigators.

At the European Oncology meeting held in the end of Sep 2012 – data from large studies were presented. The two main studies were comparing one year versus six months of Herceptin – this showed that probably one year is better than six months. The other study of one year versus two years showed that one is probably enough.

So the consensus a few years ago, was right. Twelve months is the magic figure (for now).

Adjuvant GIST – Gastro Intestinal Stromal Tumours

GIST is classically operated upon and thought to be cured by surgery. Unfortunately more and more clinicians are finding that patients have recurrence of disease. Nowadays, there are way to find possible recurrence risk rates, and treat accordingly.

If a patient has a high to moderate risk of recurrence, then they must be offered Imatinib (Glivec or Gleevec). The duration of treatment continues to be a matter of discussion – most people agree for one (1) year of treatment, but there is now data to show that three (3) years of treatment is necessary.

I suspect that treatment would be needed for long term (much longer than three years), as the survival curves at one year and three year of treatment are quite similar, when treatment is stopped.

The important thing is to ask your surgeon to consider Imatinib therapy or refer you to a MedicalOncologist for discussion.

Driving and Brain Metastasis

People who have been driving their vehicles for several years (most times decades) are really upset when we tell them that they should not be driving their cars.

In Australia the onus is on the clinicians to get affected patients to stop driving their¬†cars. The treating clinician is meant to tell the patient to stop driving and send a letter to the Driving Authority¬†to withhold/revoke the patient’s driver’s license.

The number of clinicians who even know about this is minimal!!

If a patient’s cancer has spread to their brain, the chances of seizures or altered consciousness are quite high. There is no specific time or place when things can get out of control. Also these patients have had radiotherapy, surgery, are on high dose steroids, narcotics, etc… and thus the mental cognition and reaction time is dramatically altered.

The conversation is a difficult one. But a very important one. It could save the patient’s life and others on the road.

Urine Protein and Avastin / Bevacizumab

Avastin (Bevacizumab) is a good medication in metastatic bowel cancer (both colon and rectum). It is used for extended periods of time with chemotherapy to control and reduce the burden of cancer.

It is very important to check the urinary protein while on this medications, as it does have a potential to damage the functioning of the kidney. In case, the kidneys are secreting increased amounts of proteins, it is then important to check the quantity and then if needed to stop Avastin till the kidneys recover.

We have found that a significant number of doctors forget to check urine protein, while patients are on Avastin.

Infections from Doctors

Infections can be transmitted from doctors and nurses to patients. It is well known. Hospitals across the world are trying to convince medical staff to clean their hands – wash with soap and water or use rubbing alcohol.

The other common things which are sources of infections are doctors’ white coats (which are not washed very often), neck ties (never washed), stethoscopes (hardly ever cleaned), telephones, and the list goes on.

Think about it.

Doctors as Patients: VIP syndrome

One of the nightmares for medical units across the world is to have a doctor as a patient. Everything has to be extra-careful in the discussion, tests, planning and implementation. Each thing is checked and double-checked.

I know that I am a terrible patient. I do not quite remember completing a full course of antibiotics or doing the things recommended to me.

The problem is that for some strange reason (?Murphy’s law), when we are extra-careful; things go extra wrong. Some people term it the “VIP syndrome”.

Hindu Customs and Hair Loss

I have spent time doing oncology work in India and working with patients was very rewarding.

One day in the out-patient clinic, I met with three women consecutively who were to start chemotherapy. All three women would lose their hair and it was very distressing for each of them and their families.

Two days later, I suggested to one of these women to shave their hair and make a wig out of her own hair. It seemed like a good idea to me. It was NOT a good idea for her and her family. In traditional Hindu culture, a woman would shave her hair at the time of being widowed.

No more such suggestions. Ever!!

Hair loss and Chemotherapy

One of the biggest worries about chemotherapy is hair loss. It seems to be a bigger issue than even fatigue and reduced appetite. This is what I seem to find in clinical practice. The worry seems to be more in women than men, but both genders are worried.

A lot of people are really surprised when I tell them that they would not be losing their hair. All chemotherapy drugs are not the same. Some drugs cause hair loss, some do not.

Gastro Intestinal Stromal Tumours – GIST

GIST is a truly game changing cancer. It has been around for centuries, misdiagnosed as other types of cancers. In the past few years, GIST has found to have special markers and thus the diagnosis is definitive. The main markers are c-kit (CD117) and DOG1

Treatment is to completely remove the tumour by surgery. This is possible while it is in an early stage. Once the cancer has spread, surgery is not possible (most times). Chemotherapy was as good as useless. Nothing seemed to work.

A few years ago, a pharmaceutical company launched a molecule called Imatinib (Glivec). This has changed everything for GIST. Now people with metastatic GIST, pop a pill a day and continue with life. Quite amazing.

Recent data has shown that even after surgery, Glivec should be given for at least 3 years.

Once Glivec stops working, there are other medications (Sunitinib) available.

Game changer. Looking for more such miracles.

Research and Clinical Trials

Clinical Trials for medications and drugs are broadly divided in four groups or phases:

Phase 1: Very early type of research. In some types, it would be a “first in human” study
Phase 2: Studies would have shown the medication to be relatively safe and it is now being tested for efficacy
Phase 3: The safety and efficacy have been shown to be favourable, and now it is being tested against the present standard of care
Phase 4: This study is primarily to gain more information about the medication, as it has already been approved for routine use in the market

Enrolling onto clinical trials is a good thing. It gives access to newer molecules or different ways of using older molecules. It is possible that the full benefits of the study medication may never be seen in the patients enrolled on the study, bur future generations would benefit from the same.

All trials are governed via an Ethics Committees, which may be locally or centrally based. They are the guardians of patients and their families, and would not give permission to conduct a study, unless they are convinced about safety.

The first principle remains – “First do no harm”

Children and Cancer

I find it extremely difficult to deal with children who have cancer, and their families. It is the single biggest reason why I do not treat kids. Too hard. The doctors and nurses who treat paediatric malignancies are absolutely fantastic. More power to them.

The only favourable point about kiddie cancers are that they are relatively more treatable as compared to the adult cancers. The horrible part is failing.
