This will be a randomized, controlled pilot trial of patients with histological documentation of primary colon or rectal adenocarcinoma with resectable cancer, who have not received any treatments for cancer. If patient is a candidate for surgical resection, with no planned neoadjuvant chemotherapy, then the patient is eligible. All eligible subjects will be consented prior to surgery.

The PI is studying if sorafenib/hydroxychloroquine (HCQ) will have improved efficacy when compared to sorafenib alone and in patients progressing of sorafenib the addition of HCQ would lead to disease stability in patients with advanced hepatocellular cancer (HCC).

The purpose of this study is to test the safety of neratinib at different dose levels and to find out what effects, good and bad, it has on the patients and the cancer.

In a small study at Johns Hopkins, women were treated with partial breast irradiation and chemotherapy given at the same time. We are now testing in a bigger study whether giving partial breast irradiation and chemotherapy at the same time (our new method) has the same side effects and outcomes as giving partial breast irradiation and chemotherapy at different times(older method). In this study women who had their breast cancer removed but need radiation to the breast will be randomized to partial breast irradiation at the same time as chemotherapy or partial breast radiation at a different time than chemotherapy. Randomization is like flipping a coin but in this study about 2 of every 3 women will get the new method.

Create a living biobank of PDOs from Stage I-III lung cancer patients.

The first goal of this project is to validate the superiority of semi-permanent marks used in conjunction with specialized light-based surface imaging (SIGRT) in an effort to phase out the use of permanent tattoos for the investigator's patients. The secondary goal of this project is to validate the superiority of specialized light-based surface imaging for daily radiation set-up compared to standard-of-care imaging methods using ionizing radiation, such as weekly port films or cone-beam CT (CBCT) scans during a radiation therapy course for breast cancer.

The overall goals of this Multi-Investigator Research Proposal is to further the understanding of the development and identify prognostic characteristics of liver tumors in children, particularly hepatoblastoma and its variants through a combined genomic and molecular pathology approach.

The purpose of this study is to identify genetic variants that predict progression of prostate cancer.

A research study about factors that might increase the chance of getting breast and ovarian cancers. Eligible: female 18-80 yr old; diagnosed with breast cancer under age 50; diagnosed with ovarian cancer at any age; strong family history of breast and/or ovarian cancer.

The investigators hypothesize that the combination of eflornithine and sulindac will be effective in reducing a three-year event rate of adenomas and second primary colorectal cancers in patients previously treated for Stages 0 through III colon or rectal cancer.
