    will support selecting novel agents for neoadjuvant or adjuvant strategies.

    Neoadjuvant MVAC or GC in cT2-T4N0 MIBC patients fit for cisplatin is still recommended based on OS benefit shown in meta-analyses, butreal-world adherence to NAC is low as ~40-50% ofpatients are unfit for cisplatin. The value of neoadjuvant treatment in node-positive MIBC is not clearly demonstrated requiring more accurate clinical staging and prospective studies. Adjuvant cisplatin-based chemotherapy may be considered in selected, chemo-naïve pT3-T4N+patients. Results from prospective checkpoint inhibitor immunotherapy RCTs are needed before immunotherapy becomes a recommended alternative for peri-operative treatment. Molecular tumour subtyping will support selecting novel agents for neoadjuvant or adjuvant strategies.

    With increasing survival from bladder cancer, quality of life, should be one of the main goals following radical cystectomy and bilateral pelvic lymph node dissection (PLND). This techniqueis associated with significant morbidity, which may have a critical effect on quality of life. Concerns about functional outcomes, such as continence, potency, and sexual function in women, play a role in decision making for urologists and younger patients with muscle-invasive bladder cancer. Several modifications to the classic radical cystectomy technique, include preservation of genital or pelvic organs, developing in the improvement of postoperative continence, potency rates and sexual functionin female patients.OBJECTIVE This review summarizes the organ-sparing cystectomy techniques and its functional and oncological outcomes.

    A PubMed-based literature search was conducted up to April 2020. We selected the most recent and relevant original articles, metanalysis and reviews that have provided relevant information tohout compromising oncological outcomes in well selected patients. But no one of these techniques can be recommended over the classical standard radical cystectomy. Large-scale of prospective and multi-institutional studies are needed to conclude which patients are suitable for these techniques.

    Bladder cancer is a frequent, chemosensitive disease and has shown good outcomes on several chemotherapy regimens over last 60 years. However, very little improvement has been shown in terms of overall survival and side-effects decrease.

    A review on manuscripts published in English and Spanish from 1949 including the terms chemotherapy and bladder cancer has been performed.

    Locally advanced or metastatic bladder cancer chemotherapy was initially introduced for metastasis management. The utilization of cisplatin base regimens has shown superiority over single therapy. The most commonly used regimens are cisplatine-metotrexate-vinblastine, metotrexate-vinblatine-adriamicine-cisplatin y gemcitabine-cisplatin. Neoadjuvant chemotherapy has shown to provide a minimal overall survival advantage, based on level 1 evidence. Neoadjuvant chemotherapy utilizes the same cisplatin-based regimens. Neoadjuvant chemotherapy is underutilized due to the inability to identify non-responders. Adjuvant chemotherapy is more ceatment.Non-muscle invasive bladder cancer (NMIBC) is a highly heterogeneous disease that hides classes of patients who behave significantly differently under a favorable overall prognosis facade. Individual risk stratification and good decision making improve the patient outcomes. To date, radical cystectomy remains the treatment of choice in particularly aggressive subsets of disease, also due to the lack of proven alternative bladder-sparing strategies.Cancer immunotherapy, by inhibiting the PD-1/PD-L1axis, has shown durable efficacy in the treatment of advanced and metastatic unresectable urothelial carcinoma, and is studied with great interest in early disease settings. The updated data of the KEYNOTE-057 study have recently promoted the United States (US) Food and Drug Administration (FDA) approval of pembrolizumabin patients with CIS-containing BCG-unresponsive NMIBC. This significant step forward paves the way to a new window of therapeutic opportunities, while underlining new needs and questions to be addressed.Non-muscle invasive bladder cancer has a high recurrence and progression rate. Endovesical administration of chemotherapy after transurethral resection of bladder tumors aims to minimize the recurrence and progression rates. Over last decades BCG and MMC have been gold standard treatments. Still alarge proportion of patients recur and progress. Altogether with periods of BCG shortage has facilitate the search for alternatives. In the current manuscript we review the current drug sunder study including chemotherapy, immunotherapy and gene therapy. We also updated results on recent findings on means of intravesical administration, including hyperthermia assisted by external devices. The objectives of our products are implementing new efficient and safe alternatives and the development of technologies that increase of currently used drugs. After years without improvements in the field, nowadays we have a myriad of options available. Some of those new devices will remain and reach general urologist for their applicability. Preliminary results are promising and a positive environment surrounds the urologist in charge of bladder cancer.BCG is currently the standard of care in intermediate and high risk non-invasive bladder tumors. In high-risk patients treated with BCG up to 30% will recurand 10% will progress within 2 years. click here Oncological outcomes with bladder preserving strategies are limited so radical cystectomy is recommended after BCG failure. Some promising treatments, such as check point inhibitors (PD1, PDL-1), are being studied for non-responders to BCG. Knowing the management of critical situations during BCG treatment its crucial in daily practice and clinical trials design. The aim of this study is to present these definitions and to remember some important aspect sof BCG management.Since its introduction more than 40 years ago, adjuvant treatment with BCG (Bacillus Calmette-Guérin) for non-muscle invasive bladder cancer (NMIBC) continues to be the treatment recommended in the highrisk group, and one of the most successful immunotherapies for cancer treatment. However, up to 20% of patients will progress to muscle-invasive disease after BCG treatment. On the other hand, we are facing a shortage of BCG supply worldwide. Despite its extensive clinical use, there is no clear certainty of the mechanism of action of BCG, and controversy persists regarding to the most effective dose and strains, as well as their usefulness in combined treatments with other drugs and with devices that could facilitate their action on the bladder. This article historically reviews the impact that has had BCG in the treatment of NMIBC, the current guidelines in terms of doses, strains and treatments combination, and the future that will happen with the results of the ongoing clinical trials with systemic immunotherapy, vaccines and gene therapy.
