Optimal Management of Localized Renal Cell Carcinoma: Surgery, Ablation, or Active Surveillance

David Y. T. Chen and Robert G. Uzzo

Edited by Kerrin G. Robinson

Radical nephrectomy is historically accepted as standard treatment for localized renal cell carcinoma (RCC). However, the presentation of RCC has changed dramatically over the past 3 decades. Newer alternative interventions aim to reduce the negative impact of open radical nephrectomy, with the natural history of RCC now better understood. This article discusses current surgical and management options for localized kidney cancer.

Purpose: Characterize use of postprostatectomy radiation (PPRT) for patients with prostate cancer at an NCI-designated comprehensive cancer center. Methods: We queried our prospective prostate cancer database for patients treated with 60 to 68 Gy of radiation therapy (RT) to the prostate bed after prostatectomy from 2003 to 2011. Prostatectomy cases were obtained from billing records. Patients with an intact prostate treated with definitive RT served as a control for the change in volume of patients with prostate cancer treated in the department. Chi-square analysis assessed differences between adjuvant and salvage RT cohorts. Spearman correlation assessed yearly trends in prostate-specific antigen (PSA) level at the time of referral for RT. Linear regression models tested trends for number of PPRT cases, prostatectomies, and patients with intact prostate receiving radiation across years. Results: PPRT was used to treat 475 men at Fox Chase Cancer Center from 2003 to 2011 (83 adjuvant and 392 salvage). Over time, an increased proportion of patients receiving RT to the prostate were treated with PPRT. No increase was seen in the proportion of patients treated with adjuvant RT compared with salvage RT (P=.5). Patients receiving adjuvant RT were younger, had higher pathologic Gleason score, pathologic T stage, and rates of positive margins than those receiving salvage RT. Pre-RT PSA values were inversely correlated with year (P=.005). The number of patients referred for salvage RT with a PSA of 0.5 ng/mL or less increased significantly from 7.9% in 2003 to 26.6% in 2011 (P=.002). Conclusions: A larger proportion of patients treated with RT for localized prostate cancer are now receiving PPRT. No increase was seen in the proportion of patients treated with adjuvant RT. Over time, patients with lower PSAs were referred for salvage RT.

Background: Most safety and efficacy trials of the SARS-CoV-2 vaccines excluded patients with cancer, yet these patients are more likely than healthy individuals to contract SARS-CoV-2 and more likely to become seriously ill after infection. Our objective was to record short-term adverse reactions to the COVID-19 vaccine in patients with cancer, to compare the magnitude and duration of these reactions with those of patients without cancer, and to determine whether adverse reactions are related to active cancer therapy. Patients and Methods: A prospective, single-institution observational study was performed at an NCI-designated Comprehensive Cancer Center. All study participants received 2 doses of the Pfizer BNT162b2 vaccine separated by approximately 3 weeks. A report of adverse reactions to dose 1 of the vaccine was completed upon return to the clinic for dose 2. Participants completed an identical survey either online or by telephone 2 weeks after the second vaccine dose. Results: The cohort of 1,753 patients included 67.5% who had a history of cancer and 12.0% who were receiving active cancer treatment. Local pain at the injection site was the most frequently reported symptom for all respondents and did not distinguish patients with cancer from those without cancer after either dose 1 (39.3% vs 43.9%; P=.07) or dose 2 (42.5% vs 40.3%; P=.45). Among patients with cancer, those receiving active treatment were less likely to report pain at the injection site after dose 1 compared with those not receiving active treatment (30.0% vs 41.4%; P=.002). The onset and duration of adverse events was otherwise unrelated to active cancer treatment. Conclusions: When patients with cancer were compared with those without cancer, few differences in reported adverse events were noted. Active cancer treatment had little impact on adverse event profiles.
