Summary
Wilms tumor, a common childhood cancer, can be effectively treated with preoperative chemotherapy and surgery. Early diagnosis through ultrasonography and CT scans, followed by SIOP-protocol treatment, led to successful outcomes in two young patients.
Area of Science:
- Pediatric Oncology
- Nephrology
- Diagnostic Imaging
Background:
- Wilms tumor is the most common pediatric malignancy.
- Delayed diagnosis and specific risk factors present challenges.
- Therapeutic successes highlight the need for improved management strategies.
Observation:
- Two young girls presented with nonspecific symptoms like constipation and psychomotor disturbances.
- Abdominal ultrasonography incidentally detected renal masses in both cases.
- CT scans confirmed solid, encapsulated tumors suggestive of Wilms tumor.
Findings:
- Both patients received preoperative chemotherapy followed by nephrectomy, adhering to SIOP protocols.
- Pathology revealed triphasic nephroblastoma (intermediary risk) and stage IIb nephroblastoma with focal epithelial anaplasia.
- Both patients achieved a stable cure with disease-free periods of 23 and 24 months, respectively.
Implications:
- Preoperative chemotherapy is effective, well-tolerated, and reduces tumor volume and surgical risks.
- Nonspecific symptoms in children can mask serious conditions like Wilms tumor.
- Multimodal treatment integrating chemotherapy and surgery offers a promising approach for pediatric Wilms tumor.

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Comparing the Survival Analysis of Two or More Groups
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and Cox...
