Bladder Cancer Treatment

As pointed out above there are many variables that play a role when it comes to surviving bladder cancer. Left alone, bladder cancer is deadly and would in many instances lead to death within 2 years. The following table is an attempt to summarize the information from Ref. 1 and 2 with regard to the 5 year survival rate, which is used as a tool to assess the effectiveness of the bladder cancer treatment. However, some comments are necessary to explain the data. The table shows that bladder surgery is superior to radiation therapy up to stage  T3a, where radiation is as effective as surgery. However, at stageT3b the best results come from initial chemotherapy followed by subsequent radiation, while with radiation alone the survival would be 31% less than the combination treatment.

5-year survival for bladder cancer with different treatments

TNM stage SurgeryRadiationRadical surgery and chemotherapyChemotherapy, then radiation
 Tis or  T1      66 %      66 %
 T2     59 %      46 %
 T3a     34 %      35 %
 T3b     16 %      23 % 54 %
 T4       0 %      13 % 36 %

In stageT4 the best results are obtained from initial radical bladder surgery followed by combination chemotherapy (which includes cisplatin). The best outcomes are highlighted in the table above by shading.

The reason there seems to be a wide variation between different centres, which reported these data, is that from stage T3 onward there is so much variation entering into the cancer staging (grade differences, chromosomal variations, hidden metastases) that the predictions for outcome are not that reliable. The reason that surgery does poorly at the T3b and T4 stages is that paraaortic and pelvic lymph nodes are left behind, which would subsequently kill the patient. This has to be addressed with chemotherapy, radiotherapy or both.

Similarly, with radiation alone only a certain proportion of cells gets eradicated, but the remaining cells are resistant to radiation and overcome the patient.

Even with the combination of surgery, which takes care of the local tumor, and with chemotherapy, which takes care of the metastases, there is a lot of room for improvements. The introduction of cisplatin many years back into the chemotherapy program has vastly improved survival of patients.

It appears that a more local cancer, low grade cancer and a cancer with less chromosomal abnormalities has the better 5-year survival rate. The same is true for chemotherapy followed by radiotherapy. For stage 4 Ref. 7 reported a 41% 5-year survival rate with chemotherapy alone and a 33% 5-year survival rate for more difficult cases where initial chemotherapy had to be followed by "salvage" surgery to remove surviving bladder cancer. For stage T3b and T4 it seems that surgery is not that successful and radiation is more successful, except perhaps when radical surgery where paraaortic lymph glands are removed, is combined with chemotherapy or radiation therapy. The Cancer Clinic will advise the patient as to what treatment approach will likely give the best long-term survival rate.
