Abstract
Background and aim Radiation pneumonitis (RP) is a critical pulmonary toxicity following dose delivery to the lung, and it is usually diagnosed after radiotherapy courses are completed. Because RP may result in a lethal complication, a practical method for detecting early-phase RP is awaited. In this article, we describe our experience through a variety of clinical cases and discuss treatment decisions and lessons we have made and learned. Materials and methods A daily cone-beam computed tomography (CBCT) scan was employed with a lung window setting to detect the early-phase RP during treatment courses. For the past five years, thirty patients were diagnosed with RP, and eight patients were detected during radiotherapy courses on the CBCT images. Our best efforts were made in detecting early ground-glass opacity and early RP on CBCT images prior to symptoms. The eight cases were described in more detail with CBCT or CT images. Results and discussion Initially, RP was detected at 50 Gy or greater. However, more careful CBCT observation resulted in earlier detection at around 40 Gy. Then, a new problem arose whether the treatment should be terminated. It was reported that early RP development was associated with higher-grade complications, and therefore it is preferable to terminate radiotherapy once we detect even early-phase RP. However, termination in the middle of the treatment course may significantly reduce the therapeutic effect. In our experience, patients with favorable clinical status may continue to receive radiotherapy with careful observation of lung parenchyma on CBCT images and clinical data, such as Krebs Von den Lungen-6 (KL-6) and C-reactive protein (CRP). Conclusion We have shown that early detection of RP may be feasible during radiotherapy courses by daily monitoring of CBCT lung images. Further studies are awaited to proceed.

Abstract
Dramatic progress in targeted therapy and immunotherapy has been changing clinical practices in lung cancer. With the accumulation of clinical practice, it has become clear that pre-existing interstitial pneumonia (IP) could be a risk factor for drug-induced lung injury, which has enhanced awareness regarding the difficulty in treating lung cancer with comorbid IP. Unfortunately, there is only low-grade evidence in the field of lung cancer with comorbid IP, because almost all clinical trials exclude such patients. There have been very few specialized clinical trials for patients with lung cancer and underlying IPs thus far. Therefore, it is necessary to treat such cases empirically or to give up on the treatment itself. Considering these circumstances, establishing how to treat lung cancer with comorbid IP is an urgent issue. This paper is a summary of the official statement reported by the Diffuse Lung Disease/Thoracic Oncology Assembly and the Japanese Respiratory Society (JRS) in 2017, which attempts to approach lung cancer with comorbid IP systematically.

Clin Lung Cancer 2017; 19:e269-e276. [PMID: 29208356 DOI: 10.1016/j.cllc.2017.11.004] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 10/19/2017] [Accepted: 11/10/2017] [Indexed: 10/18/2022]
Abstract
BACKGROUND We reviewed the population-based treatment patterns and outcomes for elderly patients with stage I non-small-cell lung cancer (NSCLC) treated from 2004 to 2012. PATIENTS AND METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database, we identified biopsy-proven stage I NSCLC cases diagnosed from 2004 to 2012. The patients were divided into 5-year age subsets (60-64, 65-69, 70-74, 75-79, 80-84, 85-89, and ≥ 90 years). The demographic data, therapy, and survival were compared by year. Trends in overall survival (OS), cancer-specific survival (CSS), and practice patterns were analyzed. RESULTS A total of 62,213 cases were identified. The use of surgery declined sharply with age. Patients aged 60 to 64 years had a surgical rate of 81% compared with 21% for those aged ≥ 90 years (P < .0001). Radiation use increased (from 11% to 39%; P < .0001), as did the receipt of neither surgery nor radiation (from 7% to 40%; P < .0001). When analyzing the annual trends, radiation use increased, with fewer patients forgoing treatment from 2004 to 2012 (P < .0001). From 2004 to 2011, CSS at 2 years improved significantly for patients treated with radiation alone (from 48% to 72%; P < .0001) and more subtly for those receiving surgery alone (from 87% to 91%; P < .0001). The outcomes were stable for those receiving neither surgery nor radiation (38% to 45%; P = NS). Surgical outcomes declined with advancing age (P < .0001); however, the radiation outcomes did not (P = NS). CONCLUSION With advancing age, radiation replaces surgery as the most used treatment for early-stage NSCLC. OS and CSS have improved significantly for elderly stage I NSCLC patients treated with radiation alone during a timeline concurrent with the widespread adoption of stereotactic body radiation therapy. Dedicated prospective studies are indicated, because these findings are limited by the inherent biases of using the SEER database alone.
