Intraoperative parathyroid hormone levels dynamics of cured patients with impaired renal function following parathyroidectomy for primary hyperparathyroidism.

BACKGROUND: Intraoperative parathyroid hormones have been used to establish operative success in patients with primary hyperparathyroidism. This study's aim was to assess the impact of estimated glomerular filtration rate and serum creatinine levels on the fulfillment of >50% drop and normalization of intraoperative parathyroid hormone levels. METHODS: Patients successfully treated for primary hyperparathyroidism were analyzed. The samples for parathyroid hormone were collected at baseline, 5-, 10-, and 30-minutes postexcision. The patients were classified as follows: (1) estimated glomerular filtration rate >60 mL/min, (2) estimated glomerular filtration rate <60 mL/min and serum creatinine levels <1.2 mg/dL, and (3) estimated glomerular filtration rate <60 mL/min and serum creatinine levels >1.2 mg/dL. Comparative analysis of patients achieving the >50% parathyroid hormone drop criterion and normalization of intraoperative parathyroid hormone was performed. RESULTS: One hundred-fourteen patients were distributed as follows: 88 patients (77.2%), 14 (12.3%), and 12 (10.5%) for groups 1, 2 and 3, respectively. No difference between groups in the proportion of patients fulfilling the >50% parathyroid hormone drop criterion was found. An abnormally elevated intraoperative parathyroid hormone level at 30-minute postexcision was observed in 0, 14.3, and 16.6% in groups 1, 2, and 3, respectively (P ≤ .0001). CONCLUSION: In the study, >50% parathyroid hormone drop criterion was equally achieved despite normal or reduced estimated glomerular filtration rate. When serum creatinine levels increased >1.2 mg/dL and estimated glomerular filtration rate declined <60 mL/min, the likelihood of reaching normal intraoperative parathyroid hormone levels postexcision was significantly lower.

Anal cancer in older adults: A Young International Society of Geriatric Oncology review paper.

Anal cancer is an uncommon malignancy, however, its incidence has been increasing worldwide, including among older adults. The care of older patients with anal cancer requires a multidisciplinary and comprehensive team approach to ensure improved outcomes and maintenance of quality of life, and the geriatric assessment should be a key component in the evaluation of every older patient with anal cancer. Despite older adults representing a large proportion of patients with anal cancer, they were underrepresented in trials that defined currently accepted standard therapies, including definitive chemoradiotherapy. Nonetheless, data from retrospective studies suggest that fit older patients with anal cancer should receive standard treatment similarly to their younger counterparts. This review describes the current knowledge regarding the management of anal cancer in older adults, including geriatric assessment, localized, recurrent/persistent, and metastatic disease.

Prognostic factors in cancer patients infected with SARS-CoV-2: a Latin American country results.

PURPOSE: The aim of this study was to evaluate the demographic characteristics, clinical and pathological factors, and the outcome of cancer and COVID-19 patients in Mexico. PATIENTS AND METHODS: A prospective, multicentric study was performed through a digital platform to have a national registry of patients with cancer and positive SARS-CoV-2 test results through reverse transcription quantitative polymerase chain reaction (RT-qPCR). We performed the analysis through a multivariate logistic regression model and Cox proportional hazard model. RESULTS: From May to December 2020, 599 patients were registered with an average age of 56 years with 59.3% female; 27.2% had hypertension. The most frequent diagnoses were breast cancer (30.4%), lymphoma (14.7%), and colorectal cancer (14.0%); 72.1% of patients had active cancer and 23.5% of patients (141/599) were deceased, the majority of which were men (51.7%). This study found that the prognostic factors that reduced the odds of death were gender (OR = 0.42, p = 0.031) and oxygen saturation (OR = 0.90, p = 0.0001); meanwhile, poor ECOG (OR = 5.4, p = 0.0001), active disease (OR = 3.9, p = 0.041), dyspnea (OR = 2.5, p = 0.027), and nausea (OR = 4.0, p = 0.028) increased the odds of death. In the meantime, the factors that reduce survival time were age (HR = 1.36, p = 0.035), COPD (HR = 8.30, p = 0.004), having palliative treatment (HR = 10.70, p = 0.002), and active cancer without treatment (HR = 8.68, p = 0.008). CONCLUSION: Mortality in cancer patients with COVID-19 is determined by prognostic factors whose identification is necessary. In our cancer population, we have observed that being female, younger, non-COPD, with non-active cancer, good performance status, and high oxygen levels reduce the probability of death.
