Distribution and association of cancer with mortality in end-stage renal disease patients receiving dialysis

Impact of peritoneal dialysis and hemodialysis on mortality in patients with end-stage renal disease: A systematic review and meta-analysis

INTRODUCTION

The mortality impact of peritoneal dialysis (PD) and hemodialysis (HD) in end-stage renal disease (ESRD) remains uncertain.

METHODS

A meta-analysis comparing mortality in ESRD patients on PD versus HD was conducted, including 9 studies with 7556 HD and 2651 PD patients.

RESULTS

No significant difference was found in all-cause mortality, cardiovascular-related mortality, or infection-related mortality between HD and PD patients. Hemoglobin, ferritin, and iron levels were similar in groups, but HD patients had higher albumin and BUN levels (p < 0.05). Regarding cardiovascular factors and bone minerals, total cholesterol and LDL levels were significantly lower, and calcium levels were significantly higher in the HD group compared with the PD group (p < 0.01).

CONCLUSION

Mortality does not significantly differ between HD and PD in ESRD patients, though HD is linked to higher serum albumin levels and lower levels of total cholesterol and LDL.

One-Step Robot-Assisted Complete Urinary Tract Extirpation in Man with End-Stage Renal Disease on Dialysis: The First Case Report

Urothelial carcinoma (UC) could be observed in urinary bladder (UBUC) and upper urinary tracts (UTUC). In the National Comprehensive Cancer Network guidelines for bladder cancer, extirpative surgery is indicated in certain cases. However, some extreme cases might also need the extirpation of the majority of the urinary tract, which is called complete urinary tract extirpation (CUTE). We present a patient diagnosed with high-grade UBUC and UTUC. He underwent dialysis for end-stage renal disease (ESRD) at the same time. Considering his non-functional kidneys and removing his high-risk urothelium at the same time, we performed robot-assisted CUTE to extirpate both his upper urinary tracts, urinary bladder, and prostate. In our experience, the console time was not significantly elongated, and the perioperative course was uneventful. To our knowledge, this is the first case report adopting a robotic system in such an extreme case. We conclude that robot-assisted CUTE is worth further study regarding its oncological survival outcomes and perioperative safety in patients with ESRD on dialysis.

Durable effect of pyrotinib plus capecitabine in HER-2+ breast cancer patient undergoing peritoneal dialysis: A case report and literature review

For patients with end-stage renal disease (ESRD), peritoneal dialysis (PD) and hemodialysis (HD) are important renal replacement treatments. Patients on dialysis usually have a high incidence rate of malignant tumors. In 2020, breast cancer has become the malignant tumor with the highest incidence rate in the world. Human epidermal growth factor receptor-2-positive (HER-2+) breast cancer accounts for 20%-30% of the total breast cancer patients. It is highly invasive and has a poor prognosis. Anti-HER-2 treatment is an important therapy for this type of cancer. There are few case reports of anti-HER2-targeted therapy in dialysis patients. We report a 56-year-old Chinese woman with breast cancer (cT3N1MX, Her-2+/HR-). She underwent peritoneal dialysis for 11 years since she had suffered end-stage renal disease. The clinician prescribed the regimen (pyrotinib 320mg qd + capecitabine 1g bid D1-D14 Q3W). The tumor was significantly reduced after 1 month of single administration of pyrotinib, and partially relieved after 2 months of pyrotinib + capecitabine. The main side effects were grade II hand foot syndrome and grade II diarrhea. This case shows that the combination of pyrotinib and capecitabine has potential therapeutic benefits in HER-2+ breast cancer patients with end-stage renal disease.
