Management of Patients With Metastatic Renal Cell Cancer and Bone Metastases.

BACKGROUND/AIM: Previous research has suggested that patients with metastatic renal cell cancer (mRCC) and bone metastases have a poorer prognosis compared to their counterparts with no skeletal involvement. Therefore, we analyzed the management and outcomes of such patients in our center. PATIENTS AND METHODS: We performed a retrospective study of 35 consecutive patients who received systemic treatment, largely targeted therapy, for mRCC with bone metastases. RESULTS: The median overall survival was 25 months from the time of diagnosis of mRCC. The 5-year survival rate was 16%. Survival from diagnosis of mRCC was significantly worse in patients with bone metastases present at the start of first-line systemic therapy (median 13 months) compared to delayed metastases diagnosed later during the course of disease (46 months, p=0.01). Few patients (29%) were able to receive more than two lines of systemic therapy. Bone-only metastases were uncommon (11%). CONCLUSION: Most patients with mRCC and bone metastases have limited overall survival.

Presence of Brain Metastases at Initial Diagnosis of Cancer: Patient Characteristics and Outcome.

Objective To describe the characteristics of patients who present with brain metastases already at first diagnosis of cancer and to evaluate overall survival (OS) and long-term survival. Methods Retrospective uni- and multivariate analyses in a group of 84 patients treated with different approaches. Results With respect to primary cancer type, the largest entities were adenocarcinoma non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) (34.5 and 21.4%, respectively). The most common diagnostic setting was symptomatic brain metastases (64 patients, 76.2%). Median OS was 7.2 months (one-year survival rate 31%). Four patients survived for at least three years, all had solitary metastases. The best survival was observed in the group managed with neurosurgical resection, median 17.7 months. Systemic treatment was also associated with better survival (median 9.7 vs. 2.8 months, p = 0.0001). Multivariate analysis revealed two prognostic baseline factors for OS, Karnofsky performance status (KPS) and number of brain metastases. Neurologic cause of death was uncommon (n = 14, 17%). Conclusion Long-term survival was limited and observed exclusively in the setting of a solitary brain metastasis. In patients with good KPS and limited number of brain metastases, systemic treatment as well as effective local treatment, such as resection and/or radiotherapy with sufficiently high equivalent dose, is warranted.
