Bladder cancer: Are 3 cycles of chemotherapy as good as 6 cycles – when combined with immunotherapy maintenance?

Yes; 3 is as good as 6.

The annual congress of European Society for Medical Oncology is currently underway at Berlin. Lot of exciting studies are being presented.

One of the interesting studies relate to bladder cancer. The bladder study looked at the optimum number of chemotherapy cycles that needs to be given.

Chemotherapy do cause significantly more side effects the immunotherapy. If fewer cycles are given, treatment might be more tolerable.

This bladder trial looked at giving only 3 cycles of chemotherapy compared to the standard 6 cycles.

The study found that fewer cycles improved quality of life without compromising overall benefits from the treatment

Is it useful to monitor for cancer recurrence after treatment for bowel cancer ?

No; unfortunately routine tests not useful to prolong life.

Logic dictates that early detection of bowel cancer recurrence would lead to prompt treatment and prolong life.

But cancer doesn’t do logic !

A large trial looked at usefulness of routine blood tests and scans for early diagnosis of cancer recurrence in bowel cancer patients.

The trial found that blood tests and scans were useful to diagnose recurrence early; but this early detection of recurrence ultimately did NOT improve life expectancy.

The study used tumour markers in blood [carcinoembryonic antigen CEA ] and Scans [computed tomography CT-scans] during the 5 years after surgery for bowel cancer.

Extra scans and bloods are NOT always useful.

Is radiotherapy to prostate useful even after the cancer has escaped from prostate?

Yes, it can be helpful but only in certain circumstances.

Former US President Biden is in the news this week and multiple media outlets reports that Biden is having  radiation therapy to prostate along with hormone therapy.

The news outlets also indicate that Biden has aggressive prostate cancer which has spread to the bones.

Any spread of prostate cancer to bones is classified as stage 4 prostate cancer.

If cancer has NOT spread outside the prostate, the combination of radiation and hormones could be curative .

But, with stage 4 prostate cancer, radiation is generally not curative. This is because once the cancer cells have spread, it is extremely difficult to eradicate those cancer cells permanently. 

A large UK trial ( STAMPEDE trials) found that “Radiotherapy to the prostate did NOT improve overall survival for unselected patients with newly diagnosed metastatic prostate cancer”

So if radiation does not improve survival, why did the oncologists offer radiation therapy to Biden?

Full medical details are not available and so it is difficult to give a definitive answer in Biden’s case.

There are few possibilities.

In the above mentioned STAMPEDE trial , in a smaller select group of patients, Radiation therapy did improve overall survival in men with a low metastatic burden. ( ie fewer cells have spread).

One can only speculate whether that’s been the case with regards to Mr Biden.

Is radiotherapy needed for all lymphoma patients after completing a course of chemotherapy?

In previous decades, radiotherapy was routinely used to consolidate remission after completion of chemotherapy in Lymphoma patients.

Chemotherapy alone can cure a lot of these patients. Radiotherapy can be associated with long term side effects even 10 years after completion of treatment.

So increasingly there is a tendency to omit radiotherapy in those lymphoma patients who had responded extremely well to chemotherapy alone.

Long term trial results, in a group of lymphoma patients who had mediastinal (chest) lymphoma, confirms that radiotherapy can be safely omitted in those patients who had excellent response to chemotherapy alone.

A new blood test for cancer

Cancer cells can float in a person’s blood. But finding them, in the past, used to be like “looking for a needle in a haystack”.

But new smart technology promises to detect these cancer cells easily and much early before a person develops symptoms. Detection of cancer cells at an early stage may be helpful for some patients.

A recently published study in the journal “Annals of Oncology” reports exciting results.

A Californian company called Grail has developed a blood test which seems to have a high degree of accuracy for detection of multiple cancers.

Times newspaper reports that “The NHS will begin a pilot scheme of the test with 140,000 people this year. If that is successful it will be used for millions of patients by 2025”

A word of caution though.

Just because something could be diagnosed early does not always mean that it is a good thing.

The most important thing is whether the early diagnosis can lead to better cure rates and a better quality of life.

If a test detects a cancer early but has no meaningful effect on quantity or quality of life, then it is not a good thing.

For example. Up to 80% of men have prostate cancer which can now be detected by a simple blood test called PSA. There is a good reason why we are NOT using the simple PSA test in every 80 year old.

Most 80 year old men die WITH prostate cancer rather than DUE to prostate cancer.

So why diagnose a cancer that is not causing symptoms if it is not going to make person live longer !

Should chemotherapy be used before radiotherpy for bladder cancer?

Yes, chemotherapy given before surgery or radiotherapy for invasive bladder cancer improves cure rates and survival rates.

But there is also strong U.K. data to show that Chemotherapy given along with Radiotherapy is useful because it makes radiotherapy work better .

Should chemotherapy be given before radiotherapy and then followed by more chemotherapy along with radiotherapy ?

There is lot of scientific debate on this question and well known U.K. experts are favouring this “double chemo” approach in-spite of inconclusive new data published in the European Urology journal.

The NICE guidelines on bladder cancer also favours this approach of “double” chemotherapy ( before as well as along radiotherapy).

It is a question that ideally needs to addressed in clinical trials .
