REGISTRY OF COMPLETE RESPONSES TO SUNITINIB IN SPANISH PATIENTS WITH METASTATIC RENAL CELL CARCINOMA

Pfizer62 enrolled

Overview

Observational, retrospective, multicentre study in spanish patients with metastatic Renal Cell Carcinoma (mRCC) treated with sunitinib as a first-line treatment (treatment with previous cytokine therapy is accepted) according to clinical practice who obtained a complete response (CR) to treatment in one of these 2 situations: 1. Complete response (CR) obtained exclusively with first-line sunitinib treatment (sunitinib CR). 2. Response obtained after a period of time on treatment with sunitinib in which local treatment was also performed (surgery of the residual metastasis/metastases, radiofrequency ablation or radiotherapy) to achieve the total macroscopic disappearance of the disease, according to the opinion of the physician responsible for the patient (CR + local treatment).

Eligibility

Sex: ALLMin age: 18 Days

Medical Language ↔ Plain English

Inclusion Criteria: 1. Patients who are 18 year-old or over who have been treated for metastatic renal cell carcinoma with sunitinib as first-line treatment (treatment with prior cytokine therapy is accepted) between 2007 and 30 September 2018 and who have obtained as a best treatment response the total remission of the disease in the opinion of the doctor in charge from a clinical, radiological and/or macroscopic point of view. This response must have been reached through two possible strategies: A) Systemic treatment with sunitinib alone. B) Treatment with sunitinib and subsequent local treatment for one or more residual lesions that have not responded to the drug (traditional surgery, radiotherapy, SBRT (Stereotactic Body Radiation Therapy)). 2. The duration of CR must have been confirmed with at least 2 consecutive imaging tests, without having a limit in the duration of this response. Although the patient had progressed subsequently, he/she may be included in this registry. 3. Patients from any risk group 4. Tumours of any histology Exclusion Criteria: 1. Patients treated with another drug other than Sunitinib. 2. Patients with no radiology reports proving CR. 3. Patients with no record of the dose and regimen received with Sunitinib. 4. Patients who achieved complete remission after 30 September 2018.

Outcomes

Primary Outcomes

Time to Complete Remission of Lesions

Time to complete remission of lesions was calculated as the difference between treatment start date and complete response (CR) confirmation date. As per response evaluation criteria in solid tumors (RECIST) version (v) 1.1, CR = disappearance of all known target and all non-target lesions and the absence of new lesions, normalization of tumor markers. Pathological lymph nodes must have short axis measures \<10 millimeter (mm). CR was confirmed with 2 consecutive computed tomography (CT) scans performed with at least 4 weeks between them during the follow-up of participants. Confirmation from the oncologist and radiologist was required at each site.

Time frame: From treatment initiation date to CR confirmation date, up to a maximum of approximately 13 years (from the data collected and observed retrospectively for approximately 10 months)

Duration of Complete Remission (DOR)

DOR was defined as the time from date on which the CR was identified until tumor progression, the change of treatment due to unacceptable toxicity, death from any cause or until the date of the last follow-up at the close of study. As per RECIST v1.1: CR = disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures \<10 mm. Tumor progression = at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including baseline) and an absolute increase of \>=5 mm or appearance of at least 1 new lesion. Unequivocal progression of existing non-target lesions.

Time frame: From first documented CR date until progression/death or change of treatment due to unacceptable toxicity or last follow-up date, up to a maximum of approximately 13 years (from the data collected and observed retrospectively for approximately 10 months)

Progression Free Survival (PFS)

PFS was calculated as the time from the date of CR confirmation (2nd CT scan) until the date of progression/death or change of treatment for unacceptable toxicity or censored on the date of the last follow-up. As per RECIST v1.1: CR = disappearance of target and non-target lesions and normalization of tumor markers. Pathological lymph nodes must have short axis measures \<10 mm. Tumor progression = at least a 20% increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including baseline) and an absolute increase of \>=5 mm or appearance of at least 1 new lesion. Unequivocal progression of existing non-target lesions. Analysis was performed using Kaplan-Meier method.

Time frame: From CR confirmation date until progression/death or change of treatment due to unacceptable toxicity/last follow-up date, up to maximum of approximately 13 years (data collected, observed retrospectively for approximately 10 months)
