PURPOSE OF REVIEW: Shortages in intravesical Bacillus Calmette-Guérin (BCG) immunotherapy represent a challenge in the management of high-risk nonmuscle invasive bladder cancer (HR-NMIBC). This study aimed to review the efficacy and safety of intravesical gemcitabine (GEM) and docetaxel (DOCE) for BCG-naive and unresponsive HR-NMIBC. RECENT FINDINGS: We identified six studies eligible for quantitative analysis through a systematic search according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. In the two studies in the BCG-naive setting, 1-year and 2-year pooled recurrence-free survival (RFS) were 86 and 84%, respectively. In the two studies in the BCG unresponsive setting, 6-month, 1-year and 2-year pooled high-grade recurrence-free survival (HG-RFS) were 80, 66 and 51%, respectively. Cumulative data from four studies revealed that 2.3% of patients could not complete induction therapy and 6.9% experienced treatment delay or dose reduction due to adverse events. SUMMARY: Despite the preliminary data and based on a small sample size, intravesical GEM/DOCE therapy is a highly promising combination yielding an effective and well tolerated alternative to BCG when indicated. Further large, well designed comparative studies with BCG are needed.

Dlaždicobuněčné karcinomy dutiny ústní představují nejpočetnější skupinu malignit v této oblasti. V současné době existuje mnoho prognostických histopatologických faktorů, podle kterých je maxilofaciální chirurg ve spolupráci s onkologem schopen určit prognózu a následně také nastavit vhodnou terapii. V současné době se jako velmi důležitý prognostický faktor jeví vzor invaze dlaždicobuněčného karcinomu v oblasti „invazivní fronty nádoru”. Vzor invaze souvisí s metastatickým potenciálem (a s přítomností subklinických mikroskopických metastáz) a může být odpovědí na otázku, proč ani nádory v časném stadiu nereagují na standardní léčbu. To znamená, že na základě různého invazivního vzoru se dlaždicobuněčné karcinomy dutiny ústní se stejným TNM projevují různým klinickým chováním a růstovými tendencemi a různým metastatickým potenciálem.
Squamous cell carcinomas of the oral cavity represent the largest group of malignancies in this area. Currently, there are many prognostic histopathological factors, according to which the maxillofacial surgeon in collaboration with the oncologist is able to determine the prognosis and subsequently also set an appropriate therapy. Nowadays, the squamous cell carcinoma invasion pattern in the area of the “invasive tumor front” seems to be a very important prognostic factor. The invasion pattern is connected to metastatic potential (and to the presence of subclinical microscopic metastases) and may well be the answer to why even early-stage tumors do not respond to standard therapy. That is to say, based on varying invasion pattern, oral cavity squamous cell carcinomas with identical TNM manifest varying clinical behavior and growth tendencies and a varying metastatic potential.
This study aimed to assess both efficacy and safety outcomes of lowering the dose of BCG compared to intravesical chemotherapies in non-muscle-invasive bladder cancer (NMIBC) patients using a systematic review, meta-analysis, and network meta-analysis approach. A comprehensive literature search was performed through Pubmed®, Web of ScienceTM, and Scopus® in December 2022 to identify randomized controlled trials comparing the oncologic and/or safety outcomes of reduced dose intravesical BCG and/or intravesical chemotherapies according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement. The outcomes of interest were risk of recurrence, progression, treatment-related adverse events, and discontinuation. Overall, 24 studies were eligible for quantitative synthesis. Among 22 studies that adopted induction followed by maintenance intravesical therapy, with reference to the lower-dose BCG, epirubicin was associated with a significantly higher risk of recurrence (Odds ratio [OR]: 2.82, 95% CI: 1.54-5.15), but not other intravesical chemotherapies. There were no significant differences in risk of progression among the intravesical therapies. On the other hand, standard-dose BCG was associated with a higher risk of any AEs (OR: 1.91, 95% CI: 1.07-3.41) but other intravesical chemotherapies had a comparable risk of AEs compared to lower-dose BCG. The discontinuation rate did not significantly differ between lower-dose and standard-dose BCG (OR: 1.40, 95% CI: 0.81-2.43) as well as other intravesical. According to the surface under the cumulative ranking curve, gemcitabine, and standard-dose BCG were preferable to lower-dose BCG in terms of recurrence risk; gemcitabine was also preferable to lower-dose BCG in terms of risk of AEs. In patients with NMIBC, lowering the dose of BCG decreases the risks of AEs and discontinuation rate compared to standard-dose BCG, but there is no difference in these endpoints compared to other intravesical chemotherapies. Standard-dose of BCG is preferred for all intermediate and high-risk NMIBC patients based on oncologic efficacy; however, lower-dose BCG and intravesical chemotherapies, especially gemcitabine, could be considered a reasonable alternative to BCG in selected patients who suffer from significant AEs or in case standard-dose BCG is not available.

OBJECTIVE: To assess the association between cystoscopic findings and oncological outcomes in patients with non-muscle-invasive bladder cancer (NMIBC) given that the oncological impact of quantity and quality assessment of tumours with cystoscopy has not been well verified. METHODS: Multiple databases were queried in May 2022 for studies investigating the association of oncological outcomes, such as recurrence-free (RFS), progression-free (PFS), and cancer-specific survival (CSS), with cystoscopic findings, including multiplicity, size, and gross appearance of tumours in patients with NMIBC. RESULTS: Overall, 73 studies comprising 28 139 patients were eligible for the meta-analysis. Tumour multiplicity was associated with worse RFS (pooled hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.48-1.74) and PFS (pooled HR 1.44, 95% CI 1.18-1.76) in NMIBC patients (including both Ta and T1). Tumour size (≥3 cm) was associated with worse RFS (pooled HR 1.97, 95% CI 1.69-2.30) and PFS (pooled HR 1.81, 95% CI 1.52-2.15) in NMIBC patients. In patients with T1 bladder cancer (BCa), tumour multiplicity and size (≥3 cm) were also associated with worse RFS, PFS and CSS. By contrast, among patients treated with bacillus Calmette-Guérin (BCG), tumour multiplicity was not associated with worse RFS, and tumour size (≥3 cm) was not associated with worse PFS. Sessile tumours were associated with worse RFS (pooled HR 2.14, 95% CI 1.52-3.01) and PFS (pooled HR 2.17, 95% CI 1.42-3.32) compared to pedunculated tumours. Compared to papillary tumours, solid tumours were associated with worse RFS (pooled HR 1.84, 95% CI 1.25-2.72) and PFS (pooled HR 3.06, 95% CI 2.31-4.07) in NMIBC patients, and CSS in T1 BCa patients (pooled HR 2.32, 95% CI 1.63-3.30). CONCLUSIONS: Cystoscopic findings, including tumour multiplicity, size, and gross appearance, strongly predict oncological outcomes in NMIBC patients. Cystoscopic visual features can help in the decision-making process regarding the timeliness and extent of tumour resection as well as future management such as intravesical therapy.

CONTEXT: The European Association of Urology (EAU) has released an updated version of the guidelines on non-muscle-invasive bladder cancer (NMIBC). OBJECTIVE: To present the 2021 EAU guidelines on NMIBC. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise covering all areas of the NMIBC guidelines since the 2020 version was performed. Databases covered by the search included Medline, EMBASE, and the Cochrane Libraries. Previous guidelines were updated, and the level of evidence and grade of recommendation were assigned. EVIDENCE SYNTHESIS: Tumours staged as Ta, T1 and carcinoma in situ (CIS) are grouped under the heading of NMIBC. Diagnosis depends on cystoscopy and histological evaluation of tissue obtained via transurethral resection of the bladder (TURB) for papillary tumours or via multiple bladder biopsies for CIS. For papillary lesions, a complete TURB is essential for the patient's prognosis and correct diagnosis. In cases for which the initial resection is incomplete, there is no muscle in the specimen, or a T1 tumour is detected, a second TURB should be performed within 2-6 wk. The risk of progression may be estimated for individual patients using the 2021 EAU scoring model. On the basis of their individual risk of progression, patients are stratified as having low, intermediate, high, or very high risk, which is pivotal to recommending adjuvant treatment. For patients with tumours presumed to be at low risk and for small papillary recurrences detected more than 1 yr after a previous TURB, one immediate chemotherapy instillation is recommended. Patients with an intermediate-risk tumour should receive 1 yr of full-dose intravesical bacillus Calmette-Guérin (BCG) immunotherapy or instillations of chemotherapy for a maximum of 1 yr. For patients with high-risk tumours, full-dose intravesical BCG for 1-3 yr is indicated. For patients at very high risk of tumour progression, immediate radical cystectomy should be considered. Cystectomy is also recommended for BCG-unresponsive tumours. The extended version of the guidelines is available on the EAU website at https://uroweb.org/guideline/non-muscle-invasive-bladder-cancer/. CONCLUSIONS: These abridged EAU guidelines present updated information on the diagnosis and treatment of NMIBC for incorporation into clinical practice. PATIENT SUMMARY: The European Association of Urology has released updated guidelines on the classification, risk factors, diagnosis, prognostic factors, and treatment of non-muscle-invasive bladder cancer. The recommendations are based on the literature up to 2020, with emphasis on the highest level of evidence. Classification of patients as having low, intermediate, or and high risk is essential in deciding on suitable treatment. Surgical removal of the bladder should be considered for tumours that do not respond to bacillus Calmette-Guérin (BCG) treatment and tumours with the highest risk of progression.

PURPOSE: We investigated the pathological response rates and survival associated with 3 vs 4 cycles of cisplatin-based neoadjuvant chemotherapy (NAC) in patients with cT2-4N0M0 muscle invasive bladder cancer. MATERIALS AND METHODS: In this cohort study we analyzed clinical data of 828 patients treated with NAC and radical cystectomy between 2000 and 2020. A total of 384 and 444 patients were treated with 3 and 4 cycles of NAC, respectively. Pathological objective response (pOR; ypT0-Ta-Tis-T1 N0), pathological complete response (pCR; ypT0 N0), cancer-specific survival and overall survival were investigated. RESULTS: pOR and pCR were achieved in 378 (45%; 95% CI 42, 49) and 207 (25%; 95% CI 22, 28) patients, respectively. Patients treated with 4 cycles of NAC had higher pOR (49% vs 42%, p=0.03) and pCR (28% vs 21%, p=0.02) rates compared to those treated with 3 cycles. This effect was confirmed on multivariable logistic regression analysis (pOR OR 1.46 p=0.008, pCR OR 1.57, p=0.007). On multivariable Cox regression analysis, 4 cycles of NAC were significantly associated with overall survival (HR 0.68; 95% CI 0.49, 0.94; p=0.02) but not with cancer-specific survival (HR 0.72; 95% CI 0.50, 1.04; p=0.08). CONCLUSIONS: Four cycles of NAC achieved better pathological response and survival compared to 3 cycles. These findings may aid clinicians in counseling patients and serve as a benchmark for prospective trials. Prospective validation of these findings and assessment of cumulative toxicity derived from an increased number of cycles are needed.
