Bladder Cancer Newer Treatments

Several bladder cancer newer treatments are up for discussion here.

Carcinoma in situ

Notably, for early bladder cancer (carcinoma in situ lesions) treatment with a solution containing a live anti-tuberculous vaccine (called BCG) leads to superior survival figures.

The urologist does this through a bladder catheter. Specifically, the name of the procedure is “intravesical therapy with BCG” or “BCG treatment” for short. In essence, this local therapy for superficial bladder cancer is apparently superior to intravenous chemotherapy (Ref. 4). However, phase III and phase IV trials need to establish to see which dosage schedule gives the largest survival advantage.

Radical transurethral resection of the prostate (TURP)

It is important to realize that superficial disease (Tis and T1 stage) and also T2 (which invades the muscle) can be handled with radical TURP. There was no 10-year survival advantage for a group of patients who had a radical cystectomy (=cutting the bladder out) initially (see Ref. 5). This author, when reviewing the data of the Memorial Sloan-Kettering Cancer Centre in New York, found that the group with initial radical cystectomy had a 10-year cancer survival rate of 71%, whereas the radical TURP group had an overall cancer survival rate of 76%.

Long-term follow-up of bladder cancer patients

The key in this study is that the patients had initially 3-monthly and then 6-monthly follow-up examinations where they where the specialists scrutinized them for recurrences. If the physicians found a recurrence, they immediate acted to deal with this problem. The surgeons re-resected the tumor or did a radical cystectomy. Pathological examination of the surgical specimens followed. The pathologist restaged the bladder cancers based on pathology findings. On balance, this is much more accurate than clinical staging. Based on these findings patients were treated. 34% of the initial TURP group had a recurrence and were then restaged. Their 10-year survival with stage T0 ( no more tumor found) was 82%, whereas for patients with re-staged T1 bladder cancer it was 57% (Ref.5). This is a superb long-term result for bladder cancer!


Urologists often combine radiation with some other treatment modality. Notably, radiation has good effects on its own in terms of reducing bulk of the disease and in treating pelvic lymph nodes and paraaortic lymph nodes. But it is even more effective when the physician in this case combines radiation with surgery or chemotherapy.

In fact, some groups do pre-surgical radiation and remove the remaining cancer tissue 4 weeks after radiation. On the other hand, other groups prefer to do surgery and then radiate after that. The reason for this is to treat possible local cancer spread and/or pelvic and paraaortic lymph nodes that could not be removed technically. In any event, the patient needs to be informed why a certain combination would be more advantantageous in a certain situation than the other. The key is to individualize and do what is best for the patient.

Combination chemotherapy

By and large, combination chemotherapy has been found to be much more effective in delaying tumor growth than any single chemotherapeutic agent.

As an illustration, this has already been very successful with testicular cancer in improving survival rates. However, it is important to realize that bladder cancer is a type of cancer that is inherently more resistant to both radiation and chemotherapy. Indeed, the authors in Ref.7 have shown that even with “incurable” stage 4 bladder cancer patients it is possible to achieve survivals at 5-years with an aggressive protocol. However, even though short term responses can be obtained in 30 to 50 % of patients, the long-term survival has only marginally improved.

Increased cancer regression with stimulation of immune system

With this in mind, Ref. 6 explains that attempts concentrate presently on improving the survival rates by stimulating the immune system with granulocyte colony stimulating factor (colony-forming unit factor or CFU-C factor) and other immune stimulants in order to be able to treat with higher doses of combination chemotherapy.

Another key point, using a combination chemotherapy with trexall (=methotrexate), vinblastine, doxorubicin, and cisplatin (M-VAC) these urological oncologists from New York were able to cure 41% of these patients with chemotherapy alone. 33% of patients survived 5 years by treating with this combination regimen first and subsequently removing the remaining cancer tissue surgically. In addition they also found that the better 5-year survival rates were obtained in those patients who had localized, but non-operable primary tumors initially or who had metastases restricted to lymph node sites rather than those patients who had distant metastases.

Biological therapies

There is a tendency lately to explore less toxic modalities of treatment. However, one has to remain critical of the effectiveness (called “efficacy”) of these treatments. On the other hand the researchers are very much aware that many of the present therapies that improve survival were labeled in the past as “hoax therapies”. I would like to summarize some of the steps that could be taken right now.


What we can do now regarding bladder cancer prevention


Any smoker can quit smoking

This is a proven cancer preventing step. Also anybody who is presently inhaling second hand smoke should lobby for a smoke free work environment. Some jurisdictions have this law in place and the majority of people like it.

People can change their diet

Eating more vegetables and less refined carbohydrates increases the amount of natural anti-cancer substances in the food. This reduces the negative effect on the cyclic AMP from hyperinsulinism. This zone-type diet will lead to a much stronger immune system, which will prevent or reduce the development of many cancers (Ref.8).

Chromosomal abnormalities

Chromosomal abnormalities that have been found in many bladder cancers tend to lead to a higher resistance to treatment as the cells are deficient for the normal cell functions. In order to get a lasting break-through for the patients who do not respond to the standard treatment modalities, newer methods such as monoclonal antibodies that work with the patient’s own activated macrophages or genetic vaccines etc. can be incorporated in the treatment protocol. Several Cancer Agencies around the world are investigating these methods, but nothing concrete, which would stand up to the test of prolonging long-term survival has yet been found. Watch out though as it is there that break throughs will come from.
