We report a case of primary testicular leiomyosarcoma. A 76-year-old man, who complained of left scrotal swelling for 6 months, underwent radical orchiectomy. Microscopic examination revealed intratesticular leiomyosarcoma. The patient received no adjuvant therapy and at 12 months after surgery, there had been no recurrence. Primary leiomyosarcoma of the testis is extremely rare; this is the 9th case recorded worldwide.
We investigated time-dependent changes in the relapse features of renal cell carcinoma (RCC) after curative surgery. Between 1985 and 2015, 1398 patients with RCC (1226 clear cell RCC, 89 papillary RCC, and 53 chromophobe RCC) underwent curative surgery at Yokohama City University Hospital and its affiliated hospitals. We retrospectively reviewed the clinicopathologic factors of patients with relapse after surgery. Median follow-up was 56.3 months. Recurrence occurred in 245 patients (217 clear cell RCC, 12 papillary RCC, and 3 chromophobe RCC). Papillary RCC and chromophobe RCC had no recurrence beyond 5 years after surgery, but 20 cases of clear cell carcinoma had recurrence beyond 10 years after surgery. The typical recurrence sites of clear cell RCC were lung (46.6%), bone (17.9%), liver (7.6%), and lymph nodes (6.5%). The proportion of recurrences at these typical sites was 83.9% for recurrences within 5 years, 76.3% between 5 and 10 years, and 40.0% beyond 10 years. In contrast, the proportion of retroperitoneal organ recurrence, including contralateral kidney, pancreas, and adrenal glands, increased with increasing time after surgery. Interestingly, the hazard ratio of typical site relapse decreased whereas that of retroperitoneal organ relapse increased in a time-dependent manner. In summary, clear cell RCC showed potential to relapse beyond 10 years after surgery. Recurrence at typical sites decreased whereas retroperitoneal organ recurrence increased in a time-dependent manner. Clinicians should check for recurrence at various sites beyond 10 years, especially in clear cell RCC.
ObjectiveC-reactive protein (CRP) is considered a useful serum marker for patients with RCC. However, its clinical utility in advanced metastatic renal cell carcinoma (AM-RCC), particularly in deciding whether to perform nephrectomy at the onset, is not well studied.Patients and methodsWe retrospectively evaluated 181 patients with AM-RCC, including 18 patients underwent potentially curative surgery, 111 underwent cytoreductive nephrectomy, and 52 received medical treatment only. CRP cutoff points were determined by receiver operating characteristic (ROC) curve analysis. Kaplan-Meier and Cox regression analyses were used for survival tests.ResultsROC analysis suggested that grouping patients according to 3 CRP ranges was a rational model. Patients with highly elevated CRP (≥67.0 mg/L) presented remarkably poor prognosis despite treatment (nephrectomy or medical treatment only). Cox regression models demonstrated that risk factors of overall survival for patients who underwent nephrectomy were the CRP ranges defined in this study (≤18.0 mg/L, >18.0 and <67.0 mg/L, and ≥67.0 mg/L), ECOG PS (0, 1, and ≥2), and number of metastatic organ sites (0–1 and ≥2). The retrospective design is a limitation of this study.ConclusionOur study demonstrated that the serum CRP level is a statistically significant prognostic parameter for patients with AM-RCC. The data also indicated that pretreatment serum CRP level provides useful prognostic information that helps in deciding whether to perform initial nephrectomy for patients with AM-RCC.
In Japan, freeze-dried live attenuated mumps vaccine has been used optionally since 1981. The effectiveness of mumps vaccination has been established by worldwide research since 1971. On the other hand, because of it' s live activity several untoward effects have been reported. Vaccination-related mumps orchitis is a rare adverse effect of mumps vaccine. Only 9 cases of vaccination-related mumps orchitis have been reported in Japan. We describe a case of orchitis following mumps vaccination in adolescence. A 16 years-old male has admitted because of acute orchitis with high fever and painful swelling of right testis. The patient had received vaccination with freeze-dried live attenuated mumps vaccine 16 days before admission. After admission, the bed-rest had completely relieved the symptoms on 6th hospital day. The impaired testis has maintained normal size and consistency 6 months after discharge.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
