Impact of preoperative body composition in patients with renal cell carcinoma submitted to surgical treatment.

Objective: To evaluate the impact of preoperative body composition in patients with renal cell carcinoma (RCC) undergoing surgical treatment.

Materials And Methods: This was a retrospective study of 52 patients with RCC undergoing total or partial nephrectomy. Body composition assessment was performed using the body mass index, together with computed tomography analysis at the level of the third lumbar vertebra to measure the area of visceral adipose tissue, as well as the area and density of skeletal muscle mass.

The Best Supportive Care in Stage III Non-Small-Cell Lung Cancer.

Lung cancer is a major cause of cancer deaths worldwide. Non-small-cell lung cancer (NSCLC) represents most lung cancer cases, and approximately one-third of patients present with stage III disease at diagnosis. As multiple treatment plans can be adopted for these patients depending on tumor size and nodal staging, stage III NSCLC management is challenging.

Analysis of muscle mass by computed tomography in patients with head and neck cancer: a prospective study.

Objective: To evaluate the preoperative muscle mass of patients with head and neck cancer (HNC) with computed tomography (CT), comparing the results obtained through analysis of cross-sectional areas at the level of the third lumbar vertebra (L3) with those obtained through analysis of cross-sectional areas at the levels of the third cervical and fourth thoracic vertebrae (C3 and T4, respectively).

Materials And Methods: A total of 63 patients with HNC were evaluated preoperatively. Using CT, we assessed muscle mass at L3, as well as at C3 and T4.

Preoperative evaluation of sarcopenia in patients with colorectal cancer: a prospective study.

Objective: Colorectal cancer is the third most diagnosed malignant neoplasm in the world and the fourth leading cause of cancer mortality. The loss of muscle mass in oncological patients is the main aspect of cancer-related malnutrition. Associations between sarcopenia and poor outcomes, such as high postoperative mortality, chemotherapy toxicity, and reduced survival, have been recently described.

Computed tomography assessment of body composition in patients with nonmetastatic breast cancer: what are the best prognostic markers?

Objective: To correlate body composition measures, based on computed tomography (CT) analysis of muscle mass and adipose tissue, with disease-free survival in breast cancer patients.

Materials And Methods: This single-center retrospective study included 262 female patients with nonmetastatic breast cancer. Body composition was assessed on a pretreatment CT scan (at the L3 level).

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Adults.

The nutritional status of patients submitted to hematopoietic stem cell transplant is considered an independent risk factor, which may influence on quality of life and tolerance to the proposed treatment. The impairment of nutritional status during hematopoietic stem cell transplant occurs mainly due to the adverse effects resulting from conditioning to which the patient is subjected. Therefore, adequate nutritional evaluation and follow-up during hematopoietic stem cell transplant are essential.

Computed tomography-measured body composition: correlation with postoperative morbidity and mortality in patients with gastroesophageal cancer.

Objective: To determine whether preoperative anthropometric and computed tomography (CT) measurements of body composition can predict postoperative morbidity and mortality in patients with gastric or esophageal cancer.

Materials And Methods: This was a retrospective study in which we reviewed the medical records and abdominal CT scans of patients with gastric or esophageal cancer who underwent surgery in 2015 at a cancer center. CT scans performed during routine preoperative evaluation were retrospectively assessed to measure the area of lean body mass at the level of the third lumbar vertebra, as well as the area of visceral and subcutaneous fat.
