- Objective To study how patients with urinary bladder cancer (UBC) with previous or concomitant other primary cancers (OPCs) were treated, and to investigate their prognosis. Patients And Methods Using nationwide population-based data in the Bladder Cancer Data Base Sweden (BladderBaSe), we analysed the probability of treatment with curative intent, and UBC-specific and overall survival (OS) in patients with UBC diagnosed in the period 1997-2014 with or without OPC. The analyses considered the patient's characteristics, UBC tumour stage at diagnosis, and site of OPC. Results There were 38 689 patients, of which 9804 (25%) had OPCs. Those with synchronous OPCs more often had T2 and T3 tumours and clinically distant disease at diagnosis than those with UBC only. Patients with synchronous prostate cancer, female genital cancer and lower gastro-intestinal cancer were more often treated with curative intent than patients with UBC only. When models of survival were adjusted for age at diagnosis, marital status, education, year of diagnosis, Charlson Comorbidity Index and T-stage, UBC-specific survival was similar to patients with UBC only, but OS was lower for patients with synchronous OPC, explained mainly by deaths in OPC primaries with a bad prognosis. Conclusions OPC is common in patients with UBC. Treatment for UBC, after or in conjunction with an OPC, should not be neglected and carries just as high a probability of success as treatment in patients with UBC only. The needs of patients with UBC and OPC, and optimisation of their treatment considering their complicated disease trajectory are important areas of research.

Fewer tumour draining sentinel nodes in patients with progressing muscle invasive bladder cancer, after neoadjuvant chemotherapy and radical cystectomy
- 2020

In: World journal of urology. - : Springer. - 0724-4983 .- 1433-8726. ; 38, s. 2207-2213

Journal article (peer-reviewed)abstract
- PURPOSE: To examine the relationship between the number of tumour draining sentinel nodes (SNs) and pathoanatomical outcomes, in muscle-invasive bladder cancer (MIBC), in patients undergoing neoadjuvant chemotherapy (NAC) and radical cystectomy (RC).MATERIALS AND METHODS: In an ongoing prospective multicenter study, we included 230 patients with suspected urothelial MIBC from ten Swedish urological centers. All underwent TURb and clinical staging. From the cohort, 116 patients with urothelial MIBC; cT2-cT4aN0M0, underwent radical cystectomy (RC) and lymphadenectomy with SN-detection (SNd). 83 patients received cisplatin-based NAC and 33 were NAC-naïve. The number and locations of detected SNs and non-SNs were recorded for each patient. The NAC treated patients were categorized by pathoanatomical outcomes post-RC into three groups: complete responders (CR), stable disease (SD) and progressive disease (PD). Selected covariates with possible impact on SN-yield were tested in uni -and multivariate analyses for NAC-treated patients only.RESULTS: In NAC treated patients, the mean number of SNs was significantly higher in CR patients (3.3) and SD patients (3.6) compared with PD patients (1.4) (p = 0.034). In a linear multivariate regression model, the number of harvested nodes was the only independent variable that affected the number of SNs (p = 0.0004).CONCLUSIONS: The number of tumor-draining SNs in NAC-treated patients was significantly lower in patients with progressive disease.

No increased risk of short-term complications after radical cystectomy for muscle-invasive bladder cancer among patients treated with preoperative chemotherapy : a nation-wide register-based study
- 2020

In: World journal of urology. - : Springer. - 0724-4983 .- 1433-8726. ; 38:2, s. 381-388

Journal article (peer-reviewed)abstract
- PURPOSE: Preoperative chemotherapy is underused in conjunction with radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) due to concerns for complications and delay of surgery. Prospective data on short-term complications from population-based settings with frequent use of preoperative chemotherapy and standardised reporting of complications is lacking.METHODS: We identified 1,340 patients who underwent RC between 2011 and 2015 in Sweden due to MIBC according to the Swedish Cystectomy Register. These individuals were followed through linkages to several national registers. Propensity score adjusted logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for complications and death within 90 days of surgery, comparing patients receiving preoperative chemotherapy or not.RESULTS: Minimum two cycles of preoperative chemotherapy were given to 519 (39%) of the patients, who on average tended to be younger, have higher education, better physical status, and more advanced bladder cancer than patients not receiving chemotherapy. After adjusting for these and other parameters, there was no association between treatment with preoperative chemotherapy and short-term complications (OR 1.06 95% CI 0.82-1.39) or mortality (OR 0.75 95% CI 0.36-1.55). We observed a risk reduction for gastrointestinal complications among patients who received preoperative chemotherapy compared with those who did not (OR 0.49 95% CI 0.30-0.81).CONCLUSION: This nation-wide population-based observational study does not suggest that preoperative chemotherapy, in a setting with high utilisation of such treatment, is associated with an increased risk of short-term complications in MIBC patients treated with radical cystectomy.

The increased risk for thromboembolism pre-cystectomy in patients undergoing neoadjuvant chemotherapy for muscle-invasive urinary bladder cancer is mainly due to central venous access : a multicenter evaluation

Journal article (peer-reviewed)abstract
- Purpose: To investigate if patients receiving neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) had an increased risk of thromboembolic events (TEE) and to evaluate when these events occur on a timeline starting from 6 months pre-cystectomy, during NAC-administration and 60 months post-cystectomy.Methods: Two hundred and fifty five patients undergoing radical cystectomy during 2009–2014 at three Swedish cystectomy centers (Umeå, Linköping and Sundsvall) were in-detail reviewed retrospectively, using individual medical records. One hundred and twenty nine patients were ineligible for analysis. NAC patients (n = 67) were compared to NAC-naïve NAC-eligible patients (n = 59). The occurrence of TEE was divided into different periods pre-cystectomy and post-cystectomy. Statistical analyses included Chi-squared and logistical regression tests.Results: Significant associations were found between receiving NAC and acquiring a TEE during NAC therapy pre-cystectomy. All but one pre-cystectomy event was venous and all but one of the patients received NAC. 31% (14/45) of TEEs occurred pre-cystectomy. The incidence of TEEs pre-cystectomy in NAC-naive NAC-eligible patients was only 10% (2/20), whereas the incidence of TEEs in NAC patients occurred pre-cystectomy in 48% (12/25) and 11/12 incidents were detected during NAC therapy—this including 7/11 (64%) incidents affecting veins in anatomical conjunction with the placement of central venous access for chemotherapy administration.Conclusions: There is a significantly increased risk for TEE pre-cystectomy during chemotherapy administration in MIBC patients receiving NAC, compared to the risk in NAC-naïve NAC-eligible MIBC patients. In 64% of the pre-RC TEEs in NAC patients, there was a clinical connection to placement of central venous access.
