AI Article Synopsis
- The study analyzed 180 breast cancer patients to determine the impact of serum albumin levels on survival rates from 1993 to 1999.
- Normal serum albumin levels (>3.5 g/dL) were associated with a 72% reduction in mortality risk, emphasizing their importance in prognosis.
- Low serum albumin levels were found to significantly reduce survival across all stages of breast cancer, accounting for 7.35% of the variability in patient survival times.
Article Abstract
Background: The medical literature shows several examples of an inverse relationship between serum albumin levels and survival in patients with advanced cancer.
Methods: We investigated the effect of baseline serum levels on 180 consecutively treated patients who were diagnosed with breast cancer from March 1993 to December 1999 at our institution. We investigated the effect of low levels of serum albumin (<3.5 g/dL) using univariate and the multivariate Cox regression model.
Results: Demographically, the median age of these patients was 51 years of age, with a range of 28 to 88 years. In this series, 28 patients have died and 9 have developed a recurrence of tumor. The patient distribution by tumor stage was 53, stage 1; 47, stage 2A; 29, stage 2B; 11, stage 3; 13, stage 4A; and 21, stage 4B. In this cohort, the overall 5-year survival was 69%. The Cox regression analysis found that normal levels of albumin (>3.5 g/dL) reduced the risk of death by 72% (p = .0033). Only tumor stage had a larger impact on survival (p < .0000). Other factors achieving statistical significance were overexpression of the HER2/Neu antigen (p = .0167) and breast antigen (p = .0116).
Conclusion: Univariate statistical analysis found that low levels of serum albumin adversely affected survival by a statistically significant level for all stages of breast cancer. We found that a baseline serum albumin level was a powerful prognostic variable, which accounted for 7.35% of the variation in patient survival time.

Dendrimers are a wide range of nanoparticles with desirable properties that can be used in many areas of medicine. However, little is known about their potential use in wound healing. This study examined the properties of phosphorus dendrimers that were built on a cyclotriphosphazene core and pyrrolidinium (DPP) or piperidinium (DPH) terminated groups, to be used as potential factors that support wound healing ().

Hepatic hydrothorax (HH) is a severe cirrhosis complication requiring early diagnosis and appropriate management. This study aimed to assess the impact of HH on the disease severity and mortality of cirrhotic patients and compare their clinical and biological profiles with those of patients without HH. This retrospective study involved 155 patients diagnosed with cirrhosis, of whom 31 had HH.

Background: Muscle depletion (MD) is a critical factor that influences clinical outcomes in patients with hepatocellular carcinoma (HCC). Although its role in cancer prognosis is recognized, its integration into widely used prognostic systems remains underexplored. This study aimed to evaluate the prognostic impact of MD on overall survival (OS) in HCC patients and to improve existing noninvasive prognostic models by incorporating MD-related metrics.

Amyloidosis is a rare pathology characterized by protein deposits in various organs and tissues. Cardiac amyloidosis (CA) can be caused by various protein deposits, but transthyretin amyloidosis (ATTR) and immunoglobulin light chain (AL) are the most frequent pathologies. Protein misfolding can be induced by several factors such as oxidative stress, genetic mutations, aging, chronic inflammation, and neoplastic disorders.

: Hemodialysis patients face a high mortality risk, requiring effective clinical assessments. In these patients, muscle wasting due to protein-energy wasting (PEW) leads to increased frailty, which is strongly associated with worse outcomes, including higher mortality. As muscle mass declines, so does functional capacity, making regular assessment of both muscle mass and function critical for prognostic evaluation.
