Survival Outcomes of Metastatic Non-small Cell Lung Cancer Patients With Limited Access to Immunotherapy and Targeted Therapy in a Cancer Center of a Low- and Middle-Income Country.

Objective: To describe the survival outcomes of metastatic non-small cell lung cancer patients with limited access to immunotherapy and targeted therapy in a cancer reference center in Colombia.

Methods: A retrospective analysis of metastatic non-small cell lung cancer patients treated between 2013 and 2018 was performed, majority diagnosed with adenocarcinoma. It was carried out in a public cancer reference center that provides care to patients of low and middle socioeconomic status.

Survival Outcomes of Patients With Mediastinal Germ Cell Tumors: Experience of a Cancer Center in South America.

Purpose: Mediastinal germ cell tumors (GCT) are rare neoplasms associated with poor survival prognosis. Due to their low incidence, limited information is available about this disease in South America. The objective of this study is to report the clinical characteristics and outcomes of patients with mediastinal GCT in a cancer center in Colombia.

Adult Wilms' Tumor: Case Report and Literature Review.

Wilms' tumor is childhood's most common renal tumor, and its presentation in the adult age is extremely rare. Due to the low frequency in adults, no standard management guidelines are available for this population, also the natural history of the disease and management is unclear. We present a case report of a 31-year-old woman with metastatic Wilms' tumor, with lymph node, lung and liver involvement; systemic treatment with chemotherapy was started, with complete clinical response.

Atypical Vascular Proliferation Secondary to Radiotherapy in a Patient With a History of Synovial Sarcoma.

We present the case of a 21-year-old male patient with a history of monophasic synovial sarcoma in his left thigh, which was treated with surgical resection, radiotherapy, and chemotherapy with mesna, doxorubicin, and Ifosfamide (MAI protocol). Approximately six years after the end of the oncological treatment, he presented a nodular, polypoid lesion in the left popliteal region, which was painless and fast growing. Ultimately, the biopsy was consistent with atypical vascular proliferation (AVP).
