Recently, metabolic syndrome (MetS) has become an important public health problem, and its prevalence is increasing. MetS is associated with multifactorial diseases. No reports have suggested a relationship between bladder cancer and high blood pressure, and hyperlipidemia has been reported as a possible risk factor. In the present study, we investigated the relationships between the stage and degree of malignancy of bladder cancer and MetS. Furthermore, we investigated the influence of the components of MetS on the results. We retrospectively analyzed the data of 169 patients who underwent transurethral resection of a bladder tumor in our department between Janurary 2005 and March 2011. MetS was significantly associated with a high histological grade (p < 0.05). MetS and low high-density lipo-protein were found to be significantly associated with the T stage; no other components of MetS were associated with a high stage or grade. Our results demonstrated that a lack of therapy for patients with low high-density lipoprotein levels could be riskier than was previously thought.
Abstract. There is no established standard second-line chemotherapy after the failure of the first-line cisplatin-based chemotherapy for patients with advanced or metastatic urothelial carcinoma. With regards to second-line chemotherapy, methotrexate, vinblastine, doxorubicin and cisplatin (MVAC) was used from July 2009 onwards, and paclitaxel and carboplatin (TC) was introduced in April 2014 at the National Kyushu Cancer Center. The present study aimed to assess the prognostic factors for overall survival (OS) in second-line treatment that included best supportive care (BSC), and the tolerability and efficacy of TC chemotherapy. In total, 52 patients who were confirmed to have disease progression with first-line gemcitabine and cisplatin (GC) between June 2009 and November 2016 were enrolled in the current study. In addition, 28 patients selected BSC as second-line treatment, while 24 patients received second-line chemotherapy (MVAC, n=8; TC, n=16). The median OS for BSC, MVAC and TC was 2.8, 5.4, and 12.7 months, respectively. The difference between BSC and MVAC was not statistically significant (P=0.596). However, the difference between BSC and TC was statistically significant after Bonferroni correction (P=0.002). Multivariate analyses revealed that anemia [hazard ratio (HR), 7.047; 95% confidence interval (CI), 1.553-35.636; P= 0.011], the presence of visceral metastasis (HR, 4.174; 95% CI, 1.506-13.429; P= 0.005) and second-line treatment (TC HR, 0.296; 95% CI, 0.124-0.636; P= 0.003) were independent prognostic factors. TC achieved an 18.7% overall response rate and a 56.2% disease control rate. Myelosuppression was the most common grade ≥3 toxicity, but no treatment-associated mortalities occurred during the study period. TC was associated with favorable benefits and safety, and may be considered a preferred regimen after the failure of GC.
Abstract. The aim of the present study was to investigate the association between clinical parameters and the overall survival (OS) of Japanese patients with metastatic renal cell carcinoma (mRCC). The medical records of 59 consecutive mRCC patients receiving molecular-targeted therapy were retrospectively assessed. Kaplan-Meier and log-rank analyses were used to evaluate the progression-free survival (PFS) and OS, and a multivariate Cox
Introduction
Radiation-associated sarcoma (RAS) is one of the most life-threatening complications associated with the treatment of malignant neoplasms. Because all RAS patients have a history of radiotherapy, there have been no effective treatment options when RAS is not completely resected.
Methods
We retrospectively reviewed 20 RAS patients, including 4 unresectable cases treated by carbon ion radiotherapy (CIRT).
Results
The primary diseases targeted by radiotherapy included malignant lymphoma (n=4), cervical cancer (n=3), pharyngeal cancer (n=3), breast cancer (n=2), lung cancer (n=1), rectal cancer (n=1), maxillary cancer (n=1), synovial sarcoma (n=1), and benign neoplasms (n=4). The histological diagnoses of RAS included osteosarcoma (n=8), leiomyosarcoma (n=3), undifferentiated pleomorphic sarcoma (n=3), rhabdomyosarcoma (n=1), angiosarcoma (n=1), malignant peripheral nerve sheath tumor (n=1), spindle cell sarcoma NOS (n=1), and sarcoma not further specified (n=2). The median survival time from the diagnosis of RAS was 26 months. Eleven patients underwent surgery. Five of these patients achieved a continuous disease free status or showed no evidence disease. Four patients underwent CIRT. One of these patients with leiomyosarcoma achieved a continuous disease free status, and the other patient with osteosarcoma achieved a partial response. On the other hand, 2 patients experienced Grade 3 toxicities that required surgical treatment.
Conclusion
RAS originates from various types of diseases that are treated by radiotherapy and shows diverse pathological features. Complete resection achieves a good prognosis. CIRT can be an effective and feasible option for unresectable RAS.
