Fast growing papillary renal cell carcinoma in first trimester pregnancy with postoperative inferior vena cava thrombosis: A case report

Renal cell carcinoma (RCC) is an extremely rare and fatal tumor for women of childbearing age. Consequently, the cases published in the literature are limited and medical experience with therapeutic management of newly diagnosed RCC in pregnant women is poor. We report our clinical experience with a renal tumor diagnosed in first-trimester pregnancy complicated in postoperative by an inferior vena cava thrombosis. Further reporting of such a case should help to collect more data in purpose to establish a clear, systematic and evidence guide-ligne in front of this unique situation.

Candidate SNP markers of reproductive potential are predicted by a significant change in the affinity of TATA-binding protein for human gene promoters

BACKGROUND

The progress of medicine, science, technology, education, and culture improves, year by year, quality of life and life expectancy of the populace. The modern human has a chance to further improve the quality and duration of his/her life and the lives of his/her loved ones by bringing their lifestyle in line with their sequenced individual genomes. With this in mind, one of genome-based developments at the junction of personalized medicine and bioinformatics will be considered in this work, where we used two Web services: (i) SNP_TATA_Comparator to search for alleles with a single nucleotide polymorphism (SNP) that alters the affinity of TATA-binding protein (TBP) for the TATA boxes of human gene promoters and (ii) PubMed to look for retrospective clinical reviews on changes in physiological indicators of reproductive potential in carriers of these alleles.

RESULTS

A total of 126 SNP markers of female reproductive potential, capable of altering the affinity of TBP for gene promoters, were found using the two above-mentioned Web services. For example, 10 candidate SNP markers of thrombosis (e.g., rs563763767) can cause overproduction of coagulation inducers. In pregnant women, Hughes syndrome provokes thrombosis with a fatal outcome although this syndrome can be diagnosed and eliminated even at the earliest stages of its development. Thus, in women carrying any of the above SNPs, preventive treatment of this syndrome before a planned pregnancy can reduce the risk of death. Similarly, seven SNP markers predicted here (e.g., rs774688955) can elevate the risk of myocardial infarction. In line with Bowles' lifespan theory, women carrying any of these SNPs may modify their lifestyle to improve their longevity if they can take under advisement that risks of myocardial infarction increase with age of the mother, total number of pregnancies, in multiple pregnancies, pregnancies under the age of 20, hypertension, preeclampsia, menstrual cycle irregularity, and in women smokers.

CONCLUSIONS

According to Bowles' lifespan theory-which links reproductive potential, quality of life, and life expectancy-the above information was compiled for those who would like to reduce risks of diseases corresponding to alleles in own sequenced genomes. Candidate SNP markers can focus the clinical analysis of unannotated SNPs, after which they may become useful for people who would like to bring their lifestyle in line with their sequenced individual genomes.

Hand-assisted laparoscopic radical nephrectomy in pregnancy

PURPOSE

To demonstrate the beneficial results of hand-assisted laparoscopic tumor nephrectomy in pregnancy and to emphasize the proper timing of such surgery for its crucial importance attempting to avoid fatal cancer-related outcomes as a result of late interventions of aggressive tumors.

METHODS

A report of a 32-year-old woman with a 61 × 41 mm chromophobe renal cell carcinoma (RCC) successfully treated with laparoscopic transperitoneal hand-assisted nephrectomy during the 20th week of gestation is presented.

RESULTS

The fetus was stable during the intervention; the postoperative period was uneventful; she had a normal vaginal delivery at term and gave birth to a healthy female child. The patient remained tumor-free at her 34-month follow-up.

CONCLUSION

Although the pure laparoscopic interventions have become recognized in the treatment of RCC over the last decade, these methods have their limitations and dangers as well. The hand-assistance method makes the procedure faster and safer which is especially important during second or third trimester. Renal biopsy may play a specifically important role in predicting the malignant potential of a renal tumor, whereas postponement of this surgery until after delivery, may lead to the mother's death. To our knowledge, this is the first report on hand-assisted laparoscopic nephrectomy in pregnancy.
