Pazopanib Hydrochloride Before Surgery in Treating Patients With Kidney Cancer

Inclusion

* Histologically or cytologically proven renal carcinoma with a clear cell component
* Need for optimized partial nephrectomy based on one or more of the following criteria (all applicable criteria should be recorded and one criterion designated as the primary reason):

  * Functional or anatomic solitary kidney, bilateral tumors, or pre-existing chronic kidney disease (CKD; estimated glomerular filtration rate (GFR) by Cockcroft-Gault formula \< 60 mL/min) and tumor amenable to partial nephrectomy, but partial nephrectomy would result in estimated GFR \< 30 mL/min; this estimation will be based on current estimated GFR, nuclear renal scan to estimate relative renal function (if 2 kidneys), tumor location(s), and amount of normal renal parenchyma that would need to be removed with nephrectomy
  * Radical nephrectomy is required for tumor excision; however, it would result in estimated GFR \< 30 mL/min; this estimation will be based on current estimated GFR, nuclear renal scan to estimate relative renal function (if 2 kidneys), tumor location(s), and amount of normal renal parenchyma that would need to be removed with radical nephrectomy
  * Greater than 30% likelihood that a partial nephrectomy would be associated with a high risk of significant morbidity (e.g. hemorrhage) due to proximity to the renal hilum (within 3 mm of main renal artery, renal vein or their primary branches) and/or other anatomic factors as determined by the operating surgeon
  * Renal nephrometry score of 10-12
* Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
* Karnofsky \>= 70%
* Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase \[SGOT\]) =\< 2.5 x laboratory upper limit of normal (ULN)
* Serum alanine transaminase (ALT; serum glutamic pyruvic transaminase \[SGPT\]) =\< 2.5 x laboratory upper limit of normal (ULN)
* Total serum bilirubin =\< 1.5 x ULN
* Absolute neutrophil count (ANC) \>= 1500/uL
* Platelets \>= 100,000/uL
* Hemoglobin \>= 9.0 g/dL (no transfusion permitted within 1 week)
* Serum creatinine =\< 2.5 mg/dL
* Urine to protein to creatinine (UPC) ratio \< 1; if UPC \> 1, then a 24-hour urine protein must be assessed; subjects must have a 24-hour urine protein value \< 1g to be eligible
* Prothrombin time (PT) or international normalized ratio (INR) and partial thromboplastin time (PTT) =\< 1.2 X upper limit of normal (ULN)
* Willingness and ability to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures; subjects must provide written informed consent prior to performance of study-specific procedures or assessments, and must be willing to comply with treatment and follow up
* A female is eligible to enter and participate in this study if she is of:
* Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who has had: a hysterectomy; a bilateral oophorectomy (ovariectomy); a bilateral tubal ligation; is post-menopausal
* Subjects not using hormone replacement therapy (HRT) must have experienced total cessation of menses for \>= 1 year and be greater than 45 years in age, OR, in questionable cases, have a follicle stimulating hormone (FSH) value \> 40 mIU/mL and an estradiol value \< 40pg/mL (\< 140 pmol/L)
* Subjects using HRT must have experienced total cessation of menses for \>= 1 year and be greater than 45 years of age OR have had documented evidence of menopause based on FSH and estradiol concentrations prior to initiation of HRT
* Childbearing potential, including any female who has had a negative serum pregnancy test within 2 weeks prior to the first dose of study treatment, preferably as close to the first dose as possible, and agrees to use adequate contraception; GlaxoSmithKlein (GSK) acceptable contraceptive methods, when used consistently and in accordance with both the product label and the instructions of the physician, are as follows: an intrauterine device with a documented failure rate of less than 1% per year; vasectomized partner who is sterile prior to the female subject's entry and is the sole sexual partner for that female; complete abstinence from sexual intercourse for 14 days before exposure to investigational product, through the dosing period, and for at least 21 days after the last dose of investigational product; or double-barrier contraception (condom with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide)

Exclusion

* Prior systemic treatment for RCC
* Evidence of any distant metastatic disease
* Evidence of bleeding diathesis or coagulopathy; patients with hematuria from the primary renal tumor are eligible provided all other eligibility criteria are met
* History of any one or more of the following cardiovascular conditions within the past 6 months: cardiac angioplasty or stenting; myocardial infarction; unstable angina; coronary artery bypass graft surgery; symptomatic peripheral vascular disease
* Class III or IV congestive heart failure, as defined by the New York Heart Association (NYHA)
* Prolongation of corrected QT interval (QTc) \> 480 msecs
* Hypertension that cannot be controlled by medications to \< 160/90 mmHg
* History of cerebrovascular accident, pulmonary embolism or untreated deep venous thrombosis (DVT) within the past 6 months (Note: subjects with recent DVT who have been treated with therapeutic anti-coagulating agents for at least 6 weeks are eligible)
* Prior major surgery or trauma within 28 days prior to first dose of study drug and/or presence of any non-healing wound, fracture, or ulcer (procedures such as catheter placement not considered to be major)
* Hemoptysis within 6 weeks of first dose of study drug
* Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures
* Unable or unwilling to discontinue use of prohibited medications for at least 14 days or five half-lives of a drug (whichever is longer) prior to the first dose of study drug and for the duration of the study
* Clinically significant gastrointestinal abnormalities that may increase the risk for GI bleeding including, but not limited to: active peptic ulcer disease; known intraluminal metastatic lesion/s with suspected bleeding; inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease), or other gastrointestinal conditions with increased risk of perforation; history of abdominal fistula, gastrointestinal perforation, or intra abdominal abscess within 28 days prior to beginning study treatment
* Clinically significant gastrointestinal abnormalities that may affect absorption of investigational product including, but not limited to: malabsorption syndrome; major resection of the stomach or small bowel
* Prior major surgery or trauma (NOT including biopsy of renal mass; also procedures such as catheter placement not considered to be major) within 28 days prior to first dose of study drug and/or presence of any non-healing wound, fracture, or ulcer
* Presence of uncontrolled infection
* Other severe acute or chronic medical or psychiatric conditions or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for entry into this study
