Current status and future perspectives of wilms tumor treatment in Iran.

Wilms tumor (WT) is among the most common pediatric malignancies. In this study, the authors tried to evaluate the adherence to internationally-approved WT treatment protocols in our tertiary medical center in Iran. Methods: In this retrospective study, the medical records of 72 pathologically confirmed WT patients who underwent treatment from April 2014 to February 2020 were evaluated. Demographic characteristics, histologic features of the tumors and metastases, utilized treatments, and survival rates were subsequently investigated. Results: From the total of 72 patients, 31 (43.1%) and 41 (56.9%) were males and females, respectively. The median age at the time of diagnosis was 44.0 (interquartile range: 18.5, 72.0) months. Among the patients, favorable histology was observed in 68 (94.6%) patients, while 4 (5.4%) patients had unfavorable histology. Regarding chemotherapy, 34/56 (60.7%), 4/56 (7.1%), and 18/56 (32.2%) received adjuvant, neoadjuvant, and combined chemotherapy, respectively. The mean numbers of neoadjuvant and adjuvant chemotherapy sessions were 9.4±5.6 and 14.5±11.1, respectively. 32/72 (44.4%) of the patients received adjuvant radiotherapy with a mean number of 7.3±3.6 sessions. Overall survival rates were 86% at 1-year, 74% at 3-year, and 62% at 5-year. Conclusion: Our results suggested that while the demographic characteristics of WT patients in Iran resemble those in other countries, abidance to internationally recommended protocols is relatively low. Moreover, survival rates were rather dismal in our study compared to those from other developing countries, further signifying the need for the development of a nation-specific treatment protocol for WT.

Lack of visual endoscopic appearance of ureteropelvic urothelial cancer; is it a deterrence for nephroureterectomy? A case study and literature review.

Two case reports are presented with an important question what should be done when an endoscopic appearance of the urotherial lesion is unavailable. As seen in clinical practice, many patients choose nephroureterectomy with frequent follow up procedures. The other question raised is that what should be done when the lesions are ureteroscopically inaccessible. These patients can avail the advantages of radical treatment without accepting the probable as initial form of treatment to evade the risk and detriments of unnecessary additional endoscopic procedures.
