RESUMO
OBJECTIVES: To create a new model for the prediction of overall survival in synchronous metastatic renal cell carcinoma. METHODS: Medical records of 158 patients with metastatic renal cell carcinoma diagnosed at the Yamagata University Hospital from August 2007 to February 2018 were reviewed. Among them, 77 with synchronous metastatic renal cell carcinoma were retrospectively analyzed using the univariate and multivariate analyses. A new prognostic model was constructed, followed by a bootstrap validation to estimate the model fitting. In addition, these prognostic factors were estimated in 67 metachronous metastatic renal cell carcinoma patients. RESULTS: Five independent prognostic factors were identified in synchronous metastatic renal cell carcinoma: cT3/4, cN1, high corrected calcium, >3.6 neutrophil-to-lymphocyte ratio and central nerve system metastasis. The number (%) and overall survival (95% confidence interval) in the favorable- (0 or 1 risk factor), intermediate- (2 risk factors) and poor-risk (≥3 risk factors) groups were 29 (45.3%) and 67.4 (31.8-NA), 21 (32.8%) and 16.8 (10.0-27.6), and 14 (21.9%) and 9.1 (7.3-13.7) months, respectively. The C-index was 0.72. Patients in the favorable-risk group had better overall survival with nephrectomy than without nephrectomy (hazard ratio 0.29, 95% confidence interval 0.09-0.91 with nephrectomy). In metachronous metastatic renal cell carcinoma, these prognostic factors showed no statistical differences in the overall survival. CONCLUSIONS: Prognostic factors are completely different between synchronous and metachronous metastatic renal cell carcinoma. The new model for synchronous metastatic renal cell carcinoma can predict a good candidate for cytoreductive nephrectomy.

The patient was a 61-year old male on maintenance dialysis who underwent transrectal prostate biopsy due to a high PSA level. The patient started suffering from intense pain in the anal region 1 hour after the biopsy, and in 7 hours, intense lower abdominal pain and bilious vomiting developed. Progressive anemia was observed with a giant retroperitoneal hematoma which had partially extended intraperitoneally on a non-contrast CT image. These findings might have been caused by arterial bleeding which occurred during the prostate biopsy. The general condition was stable, and the symptoms were improved by blood transfusion and conservative treatments.
RESUMO
(1) Background: Inflammatory responses induce the formation of both anti-tumor and pro-tumor neutrophils known as myeloid-derived suppressor cells (MDSCs). Intermittent intravesical infusion of Bacillus Calmette-Guérin (BCG) is an established cancer immunotherapy for non-muscle-invasive bladder cancer (NMIBC). However, the types of neutrophils induced via the inflammatory response to both tumor-bearing and BCG remain unclear. (2) Methods: We therefore analyzed neutrophil dynamics in the peripheral blood and urine of patients with NMIBC who received BCG therapy. Further, we analyzed the effects of BCG in a mouse intraperitoneal tumor model. (3) Results: BCG therapy induced the formation of CXCL10 and MHC class II-positive neutrophils in the urine of patients with NMIBC but did not induce MDSC formation. CXCL10- and MHC class II-expressing neutrophils were detected in peritoneal exudate cells formed after BCG administration. Partial neutrophil depletion using an anti-Ly6G antibody suppressed the upregulation of CXCL10 and MHC class II in neutrophils and reversed the anti-tumor activity of BCG in mouse models. (4) Conclusions: These results indicated that intracellular MHC class II- and CXCL10-expressing neutrophils indicate the state of anti-tumor activity induced via BCG. The status of neutrophils in mixed inflammation of immunosuppressive and anti-tumor responses may therefore be useful for evaluating immunological systemic conditions.
RESUMO
Urothelial carcinoma of the bladder (UCB) with glandular differentiation is a histological variant (HV) that is more likely to have positive extravesical tumors or nodes than those in pure UCB. Cisplatin-based neoadjuvant chemotherapy (NAC) prior to radical cystectomy (RC) is more effective for pure UCB; however, few reports are available on second-line chemotherapy for recurrence of UCB with HV. Here we report a 65-year-old Japanese male diagnosed with local recurrence UCB with HV after NAC + RC who safely achieved complete response with paclitaxel, carboplatin, and gemcitabine combination chemotherapy.
RESUMO
Cerebral venous sinus thrombosis (CVT) is rare but sometimes develops in association with malignant neoplasm. We report two cases of CVT that occurred during cisplatin-based chemotherapy for testicular cancer. A 46-year-old man with stage IIA non-seminomatous germ cell tumour was treated with conventional doses of etoposide and cisplatin (EP). On day 11 of the third treatment course, he developed a systemic seizure. Brain computed tomography (CT) and magnetic resonance (MR) imaging could not detect the cause. Enhanced chest-pelvic CT revealed pelvic thrombosis. Administration of phenytoin for epilepsy of unknown cause and heparin for thrombosis was started. He had completed 4 courses of EP therapy without seizure recurrence. After re-evaluating the brain CT images retrospectively, we found high density of superior sagittal sinus (SSS) and strongly suspected CVT. Another patient was a 47-year-old man with stage IIIB seminomatous germ cell tumour treated with bleomycin, etoposide, and cisplatin (BEP) therapy. On day 11 of the second treatment course, he developed a systemic seizure. Brain CT revealed subarachnoid haemorrhage localised in the right parietal lobe. CT venography revealed a filling defect in the superior sagittal sinus (SSS). MR venography revealed a SSS stenosis. We diagnosed the cause of the seizure as CVT and started administration of anticoagulant therapy. After the thrombus had diminished, chemotherapy was restarted and another 2 courses of BEP therapy was completed.
