Interstitial lung diseases (ILDs) constitute a group of more than 200 disorders, with idiopathic pulmonary fibrosis (IPF) being one of the most frequent. Telomere length (TL) shortening causes loss of function of the lung parenchyma. However, little is known about its role as a prognostic factor in ILD patients. With the aim of investigating the role of TL and telomerase activity in the prognosis of patients affected by ILDs, we analysed lung tissue samples from 61 patients. We measured relative TL and telomerase activity by conventional procedures. Both clinical and molecular parameters were associated with overall survival by the Kaplan–Meier method. Patients with IPF had poorer prognosis than patients with other ILDs (p = 0.034). When patients were classified according to TL, those with shortened telomeres reported lower overall survival (p = 0.085); differences reached statistical significance after excluding ILD patients who developed cancer (p = 0.021). In a Cox regression analysis, TL behaved as a risk-modifying variable for death associated with rheumatic disease (RD) co-occurrence (p = 0.029). Also, in patients without cancer, ferritin was significantly increased in cases with RD and IPF co-occurrence (p = 0.032). In relation to telomerase activity, no significant differences were detected. In conclusion, TL in lung tissue emerges as a prognostic factor in ILD patients. Specifically, in cases with RD and IPF co-occurrence, TL can be considered as a risk-modifying variable for death.

Introduction: Surgical resection is the most effective therapy for patients with early non-small cell lung cancer (NSCLC). Impact on quality of life (QoL) includes a period until return to work, perioperative complications and development of physical sequelae. Lobectomy is the standard procedure. However, sublobar resections have shown similar oncological outcomes preserving healthy parenchyma. We analyze if sublobar resection is associated wiht less deterioration of QoL. Methods: We performed a retrospective analysis of patients undergoing surgical resection for NSCLC between 2017 and 2019. Cases were classified according to type of resection (sublobar vs lobectomies, bilobectomies and pneumonectomies). A survey with questions related to outcomes and QoL and occupational issues was performed. Results: A total of 169 answered the survey and were followed for 36 months. Segmentectomy was performed in 69 patients (40.9%). Lobectomy was the main type of resection (56.2%). Fatigue during walking was less common in patients undergoing sublobar resections (55.1% vs 72.7%; p = 0.02). No other differences were detected in temrs of QoL between both groups. Changes in familiar relationship after surgery were higher in patients under 70 years old. Most patients had not resume their work activities at the time of consultation. Conclusion: Feeling of fatigue while walking was lower in patients undergoing sublobar resections. Changes in familiar relationship were higher in younger patients. QoL was similar in both groups.

Background/objectives: Second primary lung cancer frequently manifests in individuals who have survived head and neck cancer, with this occurrence often being attributed to shared risk factors. The objective of the present study is to compare the prognosis, in terms of survival rate, of patients who presented isolated bronchogenic carcinoma (BC) with that of patients who presented with a personal history of BC and associated oropharyngeal and oral cancer (OAOC). Methods: A retrospective longitudinal study was conducted, including all consecutive patients who underwent surgical resection with curative intent for BC in Hospital Clínico San Carlos (HCSC), Madrid, Spain, between December 1989 and December 2024. The survival rate was calculated and compared in two groups of patients: Group 1: 1594 patients with isolated BC and Group 2: 97 patients with BC and OAOC. Results: Group 2 did not show a significant difference in their 60-month survival rate in comparison to Group 1 (HR = 1.23, CI 95% 0.9–1.6) p = 0.14. But when comparing the 120-month survival rate, Group 1 showed a significantly higher survival rate (36.4%, CI 95% 33.9–39%) compared to Group 2, (25.54%, CI 95% 17.78–36.7%) HR= 1.28 (CI 95% 1–1.6), p = 0.04. Disease-free survival showed a non-significant trend of greater severity among patients with a previous history of OAOC. Conclusions: Lung cancer patients who presented with OAOC had worse overall survival compared to patients who presented with isolated lung cancer, and a significant difference was observed at 120 months of follow-up.

Interstitial lung diseases (ILDs) constitute a group of more than 200 disorders, being idiopathic pulmonary fibrosis (IPF) one of the most frequent. Telomere length (TL) shortening causes loss of function of the lung parenchyma. However, little is known about its role as prognostic factor in ILD patients. With the aim of investigating the role of TL and telomerase activity in the prognosis of patients affected by ILDs, we analysed lung tissue samples from 61 patients. We measured relative TL and telomerase activity by conventional procedures. Both clinical and molecular parameters were associated with overall survival by the Kaplan-Meier method. Patients with IPF had poorer prognosis than patients with other ILDs (p = 0.034). When patients were classified according to TL, those with shortened telomeres reported lower overall survival (p = 0.085); differences reached statistical significance after excluding ILD patients who developed cancer (p = 0.021). In a Cox regression analysis, TL behaved as a risk-modifying variable for death associated with rheumatological disorders (RD) co-occurrence (p = 0.029). Also, in patients without cancer, ferritin was significantly increased in cases with RD and IPF co-occurrence (p = 0.032). In relation to telomerase activity, no significant differences were detected. In conclusion, TL in lung tissue emerges as a prognostic factor in ILD patients, Specifically, in cases with RD and IPF co-occurrence, TL can be considered as a risk-modifying variable for death.
