Objectives: An increase in life expectancy is predicted for the general population and, by 2050, about one billion people will be older than 65 years. The Global Cancer Incidence, Mortality and Prevalence database estimates that 1.2 million people of this age will have cancer; this number represents 58% of new cases in the American population. This represents a challenge for diagnosis and treatment, given that some older people have multiple comorbidities and disabilities. Materials and Methods: This was a retrospective descriptive study of 204 patients aged 65 years and over. All had a solid tumor that was diagnosed in a private hospital from January 2015 to December 2017. Results: The median age was 72.2 years; the most frequent age group (48.5% of patients) was 65–75 years, and only a small percentage (4.4%) were aged > 85 years. The most common type of cancer was lung cancer (22.5%), followed by colorectal and urinary cancer. Most patients received cancer treatment after the disease diagnosis. Conclusion: There are no epidemiological studies of the older oncology population in Mexico. We believe it is necessary to perform larger studies to understand this population and to undertake actions to facilitate greater attention to patient diagnosis, treatment, and alleviation.

We report a case of metastases from a cancer of unknown primary whose primary site could not be identified during the appropriate pretreatment evaluation. The patient was a 58-year-old woman with a history of passive smoking and with no history of cancer in the family. Her current condition started with asthenia, adynamia, and pallor, followed by palpitations. An abdominopelvic computed tomography (CT) scan was performed, showing multiple osteolytic lesions distributed in all bone structures and axillary adenopathy on the left side. As part of the approach and given the high suspicion of multiple myeloma, tests were performed. The results were negative for multiple myeloma. A PET-CT scan was performed and showed left axillary adenopathy. The breasts and other organs were not affected. Left axillary lymph node resection revealed breast primary metastatic pleomorphic lobular carcinoma. Due to the metastatic disease (caused by the primary breast cancer), it was decided to start chemotherapy.

Introduction: Nephroblastoma, or Wilms’ tumor, is a malignant renal neoplasm commonly found in children, is extremely rare in adults representing only 0.5% of all renal neoplasms. Adult Wilms tumor is rare, to our knowledge fewer than 300 cases have been reported in the English literature to date. However, in older adults after 60 years of age, only less than 45 cases have been reported. For this reason, treatment guidelines in adults still are lacking. Prognosis in nephroblastoma for adult patients is found to be worse than in children. Case Presentation: We report the case of a 65-year-old female with lumbar fossa mass, flank pain and hematuria, and pathologic diagnosis of Wilms tumor. We performed nephrectomy. No adjuvant treatment was given. Our patient remains asymptomatic and without evidence of recurrence 12 months after the surgery. Conclusion: Nephroblastoma in the elderly presents different clinical behavior and prognosis compared to nephroblastoma in children.
