RESUMO
Inflammatory myofibroblastic tumor (IMT)is a potentially or low-grade malignant mesenchymal neoplasm, which is rare in clinic. Renomedullary interstitial cell tumor(RICT) is a clinically rare benign renal tumor. The combination of these two diseases in one patient has not been reported. A 25-year-old female patient was admitted to the hospital due to left back pain for 12 days and hematuria for 1 week. MRI of kidneys showed a mass in the left renal pelvis, which was considered as renal pelvic carcinoma. Urine cytopathological examination was negative. Robot-assisted laparoscopic radical left nephroureterectomy was performed. There was no tumor recurrence or metastasis during the follow-up for more than 6 months after operation.
RESUMO
Many clinical trials have shown that androgen deprivation therapy (ADT) combined with novel hormonal therapy or chemotherapy can improve the overall outcome of metastatic hormone-sensitive prostate cancer (mHSPC) patients. In this article, we report a patient with mHSPC diagnosed as stage T 3bN 0M 1b, who had a significant PSA decrease after receiving ADT combined with abiraterone acetate and underwent corticosteroid switch due to adverse events. This case suggest that ADT combined with abiraterone acetate could improve the overall survival of mHSPC patients, but clinicians should make individualized treatment plan based on patients special condition.
RESUMO
Objective:To investigate the experience and results of the modified lateral prostate capsule sparing robot-assisted radical cystectomy-orthotopic ileal neobladder (LPCS-RARC-OIN).Methods:From December 2018 to November 2020, 19 patients received LPCS-RARC-OIN by a single surgeon in Sun Yat-sen Memorial Hospital, Sun Yat-sen University. LPCS-RARC-OIN was performed on male patients with high-risk non-muscle-invasive bladder cancer or muscle-invasive bladder cancer cT 2N 0M 0 without tumour in the bladder neck or urethra, and prostate cancer was ruled out by MRI and serum PSA<2.5ng/ml. The average age was 57.6 years, the average IIEF-5 score was 20.4. Separating the prostatic adenoma and the lateral prostate capsule from the base to the apex of the prostate, and retaining the lateral prostate surgical capsule or lateral prostate capsule about 1-2mm thickness. Patients were followed up and urinary function, sexual function and oncological outcomes were recorded. Results:All 19 operations were finished successfully. The average operation time was 279.9 (225-345) min and average estimated blood loss was 88.9 (30-200) ml. The average postoperative hospital stays was 15.8 (9 -23) days. The average lymph node yields was 23.3 (11-42). All surgical margins were negative and no incidental prostate cancer was found. 2 weeks, 1 month, 3 months and 6 months after catheter removal, the daytime and nighttime continence were 42.1% (8/19)and 36.8% (7/19), 63.2% (12/19)and 63.2% (12/19), 78.9% (15/19) and 73.7% (14/19), 94.7% (18/19) and 89.5% (17/19), respectively. 3 months and 6 months after operation, the average IIEF-5 score was 7.2 and 10.1 points respectively. The average follow-up was 10.6 months (5.4-26.1 months)and no recurrence or distant metastasis was found in this study.Conclusions:LPCS-RARC-OIN could improve the urinary and sexual function in selected patients. However, the long-term follow up is needed for functional and oncological outcomes.
RESUMO
Objective To study the ultrastructural changes of 8 human fetus hearts of different months Method by TEM and SEM chemical digestion. Results The shape and ultrastructure of myocytes became complicated gradually with development. Conclusion All the changes are related to function of blood supply of human fetal heart.
