Prostate cancer (PCa) is the second most common cancer in men. Common treatments include active surveillance, surgery, or radiation. Androgen deprivation therapy and chemotherapy are usually reserved for advanced disease or biochemical recurrence, such as castration-resistant prostate cancer (CRPC), but they are not considered curative because PCa cells eventually develop drug resistance. The latter is achieved through various cellular mechanisms that ultimately circumvent the pharmaceutical’s mode of action. The need for novel therapeutic approaches is necessary under these circumstances. An alternative way to treat PCa is by repurposing of existing drugs that were initially intended for other conditions. By extrapolating the effects of previously approved drugs to the intracellular processes of PCa, treatment options will expand. In addition, drug repurposing is cost-effective and efficient because it utilizes drugs that have already demonstrated safety and efficacy. This review catalogues the drugs that can be repurposed for PCa in preclinical studies as well as clinical trials.

In this study, we report a case of a late-stage clival chordoma in a 29-year-old African American male and the unfortunate linear progression course since his initial diagnosis. Upon his initial encounter in 2020, radiation therapy did not offer any promising curative outcome. He was initially treated with a combination treatment of partial resection, radiation, and proposed oral imatinib, none of which modified the natural history and progression of his illness. Instead, these methods were performed as palliative measures to reduce the current size of the tumors and decrease growth rates to minimize his pain. Social issues acted as a contributory risk factor in his prognosis and due to the patient's socioeconomic barriers, he was not able to continue seeking available radiotherapy, leading to disease exacerbation. Poor adherence was noted with his follow-up. The risks of being affected by this disease are likely multifactorial and more reports of such cases need to be added to bridge this gap in the current literature. In addition, there is a gap in the current study of reports of such tumors found in diverse racial groups and in patients who are in their first few decades of life. Novel treatment strategies were reviewed, and it is expected they could generate assertive treatment guidelines.

Heterotopic mesenteric ossification (HMO) is abnormal bone formation in tissues which usually do not undergo ossification. There are approximately 75 cases reported worldwide. We present two cases of HMO. The first case is that of a 39-year-old man who presented with abdominal pain and a computerized tomography scan of the abdomen and pelvis revealed an apple core lesion resulting in small bowel obstruction. The second case is that of a 36-year-old woman who presented 2 months after undergoing robotic gastric sleeve resection complaining of weakness and emesis. An esophagogram revealed kinking at the distal esophagus. Surgical resection was performed in both, yielding the diagnosis of HMO. There are various theories as to the pathophysiology of HMO, but no clearly defined mechanism has been established. Management should be conservative whenever possible to prevent further ossification with subsequent surgical intervention.
