Metastasectomy (M) is an acceptable treatment option for selected patients. Our aim was to evaluate the effect of surgical resection (SR) of metastasis on disease recurrence and survival. Methods Using the Canadian Kidney Cancer Information System (CKCis), we identified patients who underwent surgical resection of metastatic Renal Cell Carcinoma (mRCC). We evaluated the histological features of the primary renal cancer, the sites of metastasis and whether M was complete or incomplete. The use of systemic therapy (ST) before or after M and its impact on the outcome of SR was evaluated. Kaplan Meier analysis was performed to assess the metastasis-free survival (MFS) and overall survival (OS) for patients who underwent complete or incomplete SR. Statistical analysis was performed using R. Results At the time of this analysis 624 patients with mRCC were present in the CKCis database. Of those, 127 patients underwent SR of their mRCC. Mean age at the time of M was 62 (range 26 – 87). The median time between diagnosis of RCC and mRCC was 1.46 (IQR 0 – 4.5) years. The median time between the diagnosis of mRCC and M was 0.15 (IQR 0- 0.4) years. The median follow up duration was 1.5 (IQR 0.6-3.4) years. The majority of our patients (64%) had clear cell carcinoma histology. The most common site of M was lung, bone, brain and adrenal gland in 31 (24%), 24 (19%), 14 (11%) and 11 (9%) patients respectively. Nineteen (15%) patients had ST before, 59 (46%) after surgery, and 49 (39%) did not receive any ST. Sixty-eight (54%) patient had complete resection of all visible disease (sNED), 39 (31%) had incomplete resection and 20 (16%) patients had unknown resection status. Complete SR was achieved in 13 (68%) patients who had initial ST and in 55 (51%) patients with no prior ST. Twenty-five (20%) patients developed a new site of metastasis during follow up, (23%) with incomplete resection and 19% with complete resection. At the last follow up, 22 (17%) patients were alive with no evidence of disease, 86 (68%) patients were alive with disease, 12 (9%) patients died of disease and 7 (6%) patients were lost to follow up. Conclusions SR of metastasis should be contemplated when feasible in order to increase cure rate in mRCC. ST prior to M could increase the rate of sNED. A larger patient population and longer follow up is needed to draw firm conclusions. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e648 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Ghassan A.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
