Which treatment is best for muscle-invasive bladder cancer?

Question

Hello doctor,

My 55-year-old father was recently diagnosed with high-grade muscle-invasive urothelial carcinoma. The doctors have presented two main treatment options: neoadjuvant chemotherapy followed by radical cystectomy or immediate surgery without chemotherapy. We are trying to determine which approach offers the best long-term survival. His computed tomography scan shows no metastasis, but the tumor is large and deeply invasive. He has diabetes and mild hypertension, so we are concerned about his ability to tolerate chemotherapy. However, we also worry that skipping chemotherapy might increase the risk of recurrence after surgery. Would genetic testing or biomarker analysis help determine whether he is more likely to respond well to chemotherapy? Additionally, if we proceed with radical cystectomy, what are the best urinary diversion options in terms of quality of life? We have heard that neobladders can have complications. How do they compare to ileal conduits in terms of long-term function?

Kindly suggest.

Hello,

Welcome to icliniq.com.

I understand your concerns.

Treatment options include neoadjuvant chemotherapy followed by radical cystectomy or immediate surgery without chemotherapy. Neoadjuvant chemotherapy is administered before surgery to shrink the tumor, making it easier to remove. Radical cystectomy involves removing the bladder, lymph nodes, and surrounding tissues. Immediate surgery without chemotherapy involves proceeding directly to radical cystectomy without prior chemotherapy.

Genetic testing and biomarker analysis can provide insights into the tumor’s biological characteristics. Genetic testing can identify mutations that may influence your father's response to chemotherapy, such as alterations in the ERCC2 (Excision Repair Cross-Complementation Group 2) gene, which can help predict response to cisplatin-based chemotherapy. Biomarker analysis can provide information on factors like PD-L1 (Programmed Death-Ligand 1) expression, which may influence response to immunotherapy.

Urinary diversion options after radical cystectomy include a neobladder or an ileal conduit. A neobladder is a surgically constructed bladder made from a segment of the intestine, allowing for more natural urination but with potential complications such as urinary incontinence, urinary tract infections, and metabolic changes. An ileal conduit is a passage that diverts urine to an external ostomy bag, offering a more straightforward and reliable option but requiring lifestyle adjustments due to the need for an external bag.

Quality of life considerations differ between the two options. A neobladder can provide a more natural urination experience but may require intensive follow-up care and management. An ileal conduit is generally easier to manage but involves adapting to an external ostomy bag. The choice depends on factors such as overall health, personal preferences, and long-term management considerations.

It is recommended to consult a multidisciplinary team, including a urologist, medical oncologist, and radiation oncologist, to determine the best treatment approach. Genetic testing and biomarker analysis should be considered to help inform treatment decisions. Discussing the pros and cons of neobladder and ileal conduit options with the healthcare team can help determine the best approach based on your father’s individual needs and preferences.

I hope this helps.

Thank you.
