Abstract

Insights

Patients with metastatic renal cell cancer (mRCC) and bone metastases face a poor prognosis. Survival is significantly worse if bone metastases are present at initial treatment.

Area of Science:

  • Oncology
  • Medical Research

Background:

  • Metastatic renal cell cancer (mRCC) with bone metastases is associated with poorer patient prognosis.
  • Skeletal involvement impacts survival outcomes in mRCC patients.

Purpose of the Study:

  • To analyze the management and outcomes of mRCC patients with bone metastases.
  • To evaluate the prognostic significance of bone metastasis timing in mRCC.

Main Methods:

  • Retrospective study of 35 consecutive mRCC patients with bone metastases.
  • Systemic treatment, primarily targeted therapy, was analyzed.

Main Results:

  • Median overall survival was 25 months from mRCC diagnosis; 5-year survival was 16%.
  • Patients with bone metastases at first-line therapy start had significantly worse survival (13 months) vs. delayed metastases (46 months).
  • Few patients (29%) received >2 lines of therapy; bone-only metastases were uncommon (11%).

Conclusions:

  • Most mRCC patients with bone metastases have limited overall survival.
  • Early bone metastasis presentation negatively impacts survival in mRCC.

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...
