Background/Purpose:
In recent years, length of hospital stay has decreased, necessitating smoother discharge support. However, in patients with cancer receiving chemotherapy, longer hospital stays are associated with an increased incidence of adverse events. Moreover, no studies have examined indicators of the risk of prolonged hospitalization before treatment initiation. Specifically, reports clarifying the relationship between blood data, such as serum albumin (albumin) levels, and length of hospital stay are lacking. Therefore, this study aimed to investigate the characteristics of male patients with lung cancer undergoing chemotherapy and examine the factors related to length of hospital stay.
Materials And Methods:
This was a cohort study of 42 male patients with lung cancer undergoing chemotherapy (mean age: 70 ± 6 years; body mass index: 22 ± 3 kg/m²; Charlson comorbidity index: 4 ± 2 points; performance status (PS): 1 ± 0). Measurement items included comorbidities, frailty, PS, the functional independence measure, the Barthel Index, and biochemical data. Multiple regression analysis was used to examine the influence of each indicator on length of hospital stay, with a significance level of 5%.
Results:
Multiple regression analysis showed a significant association between albumin levels at admission and length of hospital stay (β = -0.512, t = -3.624, p < 0.001).
Conclusion:
The results of this study suggest that lower albumin levels at admission may lead to prolonged hospital stays in male patients with lung cancer undergoing chemotherapy. These findings indicate that a poor albumin status before chemotherapy may be related to length of hospital stay.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
02:49Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
