Hereditary Leiomyomatosis

383 Background: 2-(18F) fluoro-2 deoxy-D-glucose (FDG) PET/CT is a useful tool in the staging of malignancies. In patients with kidney cancer, the role of FDG is limited in those with clear-cell histology and remains to be evaluated with other subtypes. Kidney cancer associated with hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is characterized by a defect in the Krebs cycle rendering these tumors highly dependent on aerobic glycolysis (the ‘Warburg effect’) with high glucose uptake to fulfill their energy requirements; we hypothesized that FDG PET/CT may have excellent sensitivity for staging in this condition. Methods: We retrospectively reviewed patients with HLRCC kidney cancer that underwent FDG PET/CT in conjunction with anatomic imaging at our institution. The ability of FDG PET/CT to detect malignant lesions (defined using pathologic or radiologic criteria) was evaluated. Results: A total of 30 patients underwent 42 PET /CTs. Conventional imaging identified a total of 107 lesions. Both patient and lesion-based analyses were performed. A total of 90 lesions, including ten renal lesions, were classified as malignant. 76 of 80 extra-renal lesions were correctly identified as malignant by PET/CT (sensitivity, 95%, CI 88-98%). In contrast, only 4 of 10 renal lesions were correctly identified as malignant (sensitivity, 40%, CI 17-69%). 11 of 12 histologically confirmed extra-renal lesions were PET avid (sensitivity, 92%, CI-64-98%). 10 of 12 (83%) benign lesions associated with HLRCC including uterine/cutaneous leiomyomas and adrenal nodules were PET avid. In a patient based analysis, all 18 patients with extra-renal spread of kidney cancer were correctly identified (sensitivity 100%, CI 82-100%). Conclusions: FDG PET/CT is a highly sensitive diagnostic modality for identifying metastatic kidney cancer associated with HLRCC. Prospective studies evaluating the utility of PET/CT imaging to characterize response to systemic therapy are currently underway.

Hereditary Leiomyomatosis

Abstract Background The objective of this study is to discuss clinical characteristics and treatments of hereditary leiomyomatosis renal cell carcinoma on the basis of 2 cases and to review recent literature, in order to present medical advances. Methods A 29-year old male patient came to our hospital because of a huge tumour on the right kidney. Enhanced CT showed that the tumour was about 15.5*10.5 cm, and was considered to be malignant. Another case was a 38-year old female patient. She complained was found to have a right kidney tumour in a routine physical examination. Enhanced CT showed an early-stage tumour of about 4.3*3.7 cm on the lower pole of the right kidney. The male patient underwent open radical nephrectomy and the female patient underwent laparoscopic radical nephrectomy and extensive retroperitoneal lymph node dissection. The two patients underwent genetic testing and were diagnosed as having hereditary leiomyomatosis with renal cell carcinoma. Results The postoperative pathology in both patients revealed type 2 papillary renal cell carcinoma but with different prognosis. The male patient suffered multiple metastasis 10 months post-operation. The metastatic tumour of the abdominal wall was resected to confirm recurrence and hereditary leiomyomatosis renal cell carcinoma was diagnosed by the genetic test. While the female patient had a specific family history and uterine leiomyomas, the genetic test helped us to identify hereditary leiomyomatosis renal cell carcinoma pre-operation. Because of the early diagnosis and timely treatment, the female patient was considered to have a good prognosis. Conclusion Hereditary leiomyomatosis renal cell carcinoma is a rare hereditary disease resulting from FH gene mutation. There are currently no effective treatments.Our cases demonstrate that hereditary leiomyomatosis renal cell carcinoma is a very aggressive disease. Early screening and surveillance are recommended for patients with a family history or who are at risk of hereditary leiomyomatosis renal cell carcinoma. Surgical and palliative therapy still play an important role in clinical treatment.

Renal cell carcinoma is a term that represents multiple different disease processes, each driven by different genetic alterations, with distinct histology, and biological potential which necessitates divergent management strategies. This review discusses the genetic alterations seen in several forms of hereditary kidney cancer and how that knowledge can dictate when and how to intervene with a focus on the surgical management of these tumors.

Abstract Background BCL2L13 belongs to the BCL2 super family, with its protein product exhibits capacity of apoptosis-mediating in diversified cell lines. Previous studies have shown that BCL2L13 has functional consequence in several tumor types, including ALL and GBM, however, its function in kidney cancer remains as yet unclearly. Methods Multiple web-based portals were employed to analyze the effect of BCL2L13 in kidney cancer using the data from TCGA database. Functional enrichment analysis and hubs of BCL2L13 co-expressed genes in clear cell renal cell carcinoma (ccRCC) and papillary renal cell carcinoma (pRCC) were carried out on Cytoscape. Evaluation of BCL2L13 protein level was accomplished through immunohistochemistry on paraffin embedded renal cancer tissue sections. Western blotting and flow cytometry were implemented to further analyze the pro-apoptotic function of BCL2L13 in ccRCC cell line 786-0. Results BCL2L13 expression is significantly decreased in ccRCC and pRCC patients, however, mutations and copy number alterations are rarely observed. The poor prognosis of ccRCC that derived from down-regulated BCL2L13 is independent of patients’ gender or tumor grade. Furthermore, BCL2L13 only weakly correlates with the genes that mutated in kidney cancer or the genes that associated with inherited kidney cancer predisposing syndrome, while actively correlates with SLC25A4. As a downstream effector of BCL2L13 in its pro-apoptotic pathway, SLC25A4 is found as one of the hub genes that involved in the physiological function of BCL2L13 in kidney cancer tissues. Conclusions Down-regulation of BCL2L13 renders poor prognosis in ccRCC and pRCC. This disadvantageous factor is independent of any well-known kidney cancer related genes, so BCL2L13 can be used as an effective indicator for prognostic evaluation of renal cell carcinoma.
