Abstract
In the event of a radiological accident or terrorist attack, whole- or partial-body exposure can injure the lungs. To simulate such an incident, we used a single fraction of total-body irradiation (TBI) or whole-thoracic irradiation to induce pneumonitis or pulmonary fibrosis, respectively, in a rat model. The superoxide dismutase and catalase mimetic EUK-207 was given by subcutaneous injection (20 mg/kg/day, 5 days per week, once daily) starting at 7 days after irradiation and stopping before pneumonitis developed. After TBI, morbidity and the increase in breathing rates associated with pneumonitis were significantly improved in rats treated with EUK-207 compared to rats receiving irradiation alone. At 42 days after TBI (the peak of pneumonitis) changes in vascular end points including pulmonary hemodynamics ex vivo and relative arterial density in lungs were also mitigated by EUK-207. At 7 months after whole-thoracic irradiation, EUK-207 reduced synthesis of collagen as assessed by the Sircol collagen assay and Masson's trichrome staining. Our results demonstrate promise for EUK-207 as a mitigator of radiation pneumonitis and fibrosis. We also demonstrate for the first time mitigation of multiple vascular injuries in the irradiated lung in vivo by EUK-207.

Abstract
OBJECTIVES A sleeve lobectomy is a widely accepted procedure for enabling the pulmonary parenchyma to be spared. Induction chemoradiotherapy (CRT) followed by surgery is one treatment option for locally advanced non-small cell lung cancer (NSCLC), but CRT is considered to have a negative effect on subsequent surgery, especially for anastomotic healing. In this study, we describe our experience performing sleeve lobectomies and the associated anastomotic complications after induction CRT. METHODS The medical records of NSCLC patients who underwent surgery after receiving CRT were reviewed. The relationships between anastomotic complications and clinicopathological factors were examined. RESULTS Between December 1998 and October 2011, a total of 104 patients received CRT followed by surgery. Among them, 14 NSCLC patients underwent a bronchial sleeve resection: nine patients underwent a right upper lobe resection, two patients underwent a left lingular division and lower lobe resection and one patient each underwent a right lower lobe, a right upper and middle lobe and a right middle and lower lobe resection. A bronchopleural fistula at the anastomosis occurred in two patients. A pulmonary arterial (PA) branch to the spared lobe had been sacrificed in both of these patients because of tumour involvement. In contrast, the PA branches to the spared lobes were preserved in 11 of the 12 patients who did not exhibit anastomotic complications (P = 0.033). CONCLUSIONS Our experience strongly suggests that the sacrifice of the PA branch to the spared lobe is a possible risk factor for anastomotic complications for a sleeve lobectomy after induction CRT.

Abstract
PURPOSE To investigate radiographic and computed tomography features of radiation-induced organizing pneumonia syndrome after breast-conserving surgery. MATERIALS AND METHODS The appearances and distribution of lung parenchymal abnormalities were retrospectively analyzed on chest radiographs (n = 12) and computed tomography scan images (n = 10) of 12 women (range 37-78 years, mean 55.8 years) with radiation-induced organizing pneumonia syndrome after breast-conserving surgery. RESULTS The principal radiographic feature was an airspace filling pattern in all patients that involved the middle and lower lung zones in 10 of the 12 patients. Multi-focal lesions manifesting airspace consolidation surrounded by ground-glass opacities were the predominant CT finding in all 10 of these patients. The main lesion was predominantly located in the lung periphery in nine patients and contiguously extended to the central portion of the lung in seven patients. Frequent ancillary findings were airway dilation within the consolidation and lobar volume loss in nine and eight patients, respectively. All had solitary (6/10) or multifocal (4/10) distant lung opacities, mostly consistent with the finding of ground-glass opacities (9/10). Migration of the lung disease was observed in ten patients on subsequent radiographs. CONCLUSION The cardinal radiologic feature of this syndrome is airspace consolidation surrounded by ground-glass opacification with airway dilation and volume loss, involving primarily the irradiated, subpleural area, along with distant opacities.

Abstract
Three-dimensional (3D) conformal radiation therapy (CRT) and stereotactic body radiation therapy (SBRT) are designed to deliver the maximum therapeutic radiation dose to the tumor, allowing improved local disease control, while minimizing irradiation of surrounding normal structures. The complex configuration of the multiple beams that deliver the radiation dose to the tumor in 3D CRT and SBRT produces patterns of lung injury that differ in location and extent from those seen after conventional radiation therapy. Radiation-induced changes in lung tissue after 3D CRT and SBRT occur within the radiation portals. The imaging appearance of irradiated tissues varies according to the time elapsed after the completion of therapy, with acute-phase changes of radiation pneumonitis represented by ground-glass opacities and consolidation and with late-phase changes of radiation fibrosis manifesting as volume loss, consolidation, and traction bronchiectasis. Knowledge of treatment timelines and radiation field locations, as well as familiarity with the full spectrum of possible radiation-induced lung injuries after 3D CRT and SBRT, is important to correctly interpret the abnormalities that may be seen at computed tomography (CT). Differential diagnoses in this context might include infections, lymphangitic carcinomatosis, local recurrence of malignancy, and radiation-induced tumors. The integration of morphologic information obtained at CT with metabolic information obtained at positron emission tomography is helpful in distinguishing radiation-induced parenchymal abnormalities from residual, recurrent, and new cancers. Thus, multimodality follow-up imaging may lead to substantial changes in disease management.

Abstract
We report a case of fever, dyspnea, respiratory failure and migratory, recurrent and bilateral lung opacities 4 months after radiotherapy and hormone therapy following surgery for breast cancer. Computerized tomography (CT) scans showed infiltrates outside the radiation fields. Bronchoalveolar lavage revealed lymphocytic alveolitis, whereas laboratory analysis demonstrated a mild systemic inflammation. Systemic steroids resulted in clinical and radiological improvement, but a disease relapse was evident at withdrawal of therapy, with definitive clinical and radiological normalization after a second cycle of therapy. This is a case of cryptogenic organizing pneumonia (COP) (previously known as bronchiolitis obliterans organizing pneumonia) primed by radiotherapy, as in previously reported cases. It is extremely important to be aware of the possibility of this complication, in order to optimize radiation and hormone treatment of breast cancer.

Abstract
Introduction Adjuvant local-regional radiotherapy (LRRT) is routinely recommended for breast cancer patients. It is well known being related to pulmonary side-effects. We studied post-RT radiological changes on X-ray and CT, and correlated the findings with Quality of Life (QoL), common dosimetric factors and co-variates. The results were compared with a previously reported cohort of 137 irradiated women. Methods 88 women underwent chest X-ray and CT pre-and 4-5 months after 3-D planned LRRT, minimizing the dose to the ipsilateral lung to V20 < 30%. The lung field was divided into 3 regions and the development of post-RT density changes were graded (0-3). Patients with radiological changes were compared with non-responders. Clinical symptoms were registered and data on patient and treatment related co-variates were gathered prospectively. The ipsilateral lung dosimetric factors V13, V20, V30 and mean dose were calculated and QoL was assessed before and 4 months after RT. Results The use of dose-volume constraints significally reduced moderate-severe radiological changes on chest X-ray compared with our earlier study (Chi square trend test: p < 0.001). Symptomatic pneumonitis was also rare in the present study. No agreement was found between CT and chest X-ray as diagnostic tools for post-RT pneumonitis. V13 correlated independently with radiological changes on CT (logistic regression: p = 0.04; ROC area: 0.7). The Co-variates smoking habits, age, chemotherapy, endocrine or trastuzumab therapy did not influence the outcome on multivariate analysis. QoL changes in physical function, i.e. fatigue, dyspnoea were not detected but there was a trend for a worse recovery after chemotherapy in patients with high V13 (Spearman Rank Correlation: p < 0.05). Conclusions The use of dose-volume constraints significantly reduced post-RT radiological changes on chest X-ray in LRRT for BC. The lung changes on CT were also generally limited when we used this strategy and was not always picked up on chest X-ray. Variation in V13 alone was correlated with occurrence of lung changes on CT.

Abstract
Studies of uranium miners on the US Colorado Plateau have identified associations between exposure to radon progeny and risk of lung cancer. This study added 15 years of mortality follow-up for the 4,137 miners (primarily white or American Indian) in the Colorado Plateau cohort. The cohort experienced 209 new lung cancer deaths. For white miners, the standardized mortality ratio for lung cancer compared with the regional population was 3.99 (95% confidence interval: 3.43, 4.62) for the period 1991-2005. For American Indian miners, the lung cancer standardized mortality ratio was 3.27 (95% confidence interval: 2.19, 4.73). These standardized mortality ratios have not declined substantially since the 1980s. Internally standardized rate ratios by radon exposure category over the entire follow-up period are similar to those based on earlier follow-up, although estimates within smoking categories demonstrated improved precision. The apparent interaction between radon and smoking in causing lung cancer remains submultiplicative but greater than additive. Mortality rates from silicosis remain highly elevated in the cohort. Elevated mortality rates were observed from interstitial pulmonary fibrosis, multiple myeloma, and non-Hodgkin lymphoma. Significant trends were observed with increased radon exposure in silicosis and pulmonary fibrosis mortality and in the incidence of diabetes-related end-stage renal disease among white miners.

Abstract
PURPOSE Radiotherapy (RT) after conservative surgery for breast cancer involves part of the pulmonary parenchyma with a potential detrimental effect of reducing the normal functional reserve. Such an effect deserves to be studied in depth, considering the given long life expectancy of these women. We prospectively analyzed high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs) with correlation with dosimetric data from RT. METHODS AND MATERIALS Lung HRCT and PFTs were performed in 41 women who had undergone conservative surgery for breast cancer before and 3 and 9 months after postoperative RT. The PFTs included forced vital capacity, forced expiratory volume in 1 s, total lung capacity, maximal expiratory flow at 50% and 25% of vital capacity, and the diffusion capacity of carbon monoxide. HRCT was matched with the RT treatment plan images to analyze the dosimetric correlation. RESULTS At 3 months after RT, the lung alterations were classified at HRCT as follows: 46.3% were Grade 1, 24.4% Grade 2, and 7.3% Grade 3, and at 9 months, 58.5% were Grade 1, 19.5% Grade 2, and 0% Grade 3. The PFTs showed a significant decrease at 3 months, with only partial recovery at 9 months. Chemotherapy, but not hormonal therapy, was associated with PFT changes. The grade of fibrosis increased with increasing lung volume treated to a dose > or = 25 Gy. CONCLUSION Lung changes, mainly related to damage to the alveolar-capillary barrier and smallest airway ramifications, were observed at 3 months, with only partial recovery at 9 months after RT. Minimizing the lung volume receiving > or = 25 Gy could reduce pulmonary toxicity.

Abstract
Breast cancer (BC) accounts for >30% of all new cancer patients among women but with increased early detection rates and improved adjuvant therapy, the 5-year survival rate presently reaches >85%. As the number of BC survivors increases, research into the sequelae of the cancer and its treatment on quality of life is a priority. Understanding the potential complications of treatment and developing effective rehabilitation techniques can reduce the impact of such effects on activities of daily life. The aim of this review is to discuss the major sequelae of treatment for BC, and the physiotherapist's role in the prevention and treatment of such complications. Breast cancer treatment can result in pulmonary and upper extremity morbidities that may manifest either early or late. Prevention and treatment of lymphoedema, scar adherence and pulmonary complications can be achieved. Additionally pain reduction and maintenance of range of movement, muscle strength and adequate posture are parts of physiotherapy, which is an important component in the rehabilitation of women with BC.

Abstract
Common complications of thoracic radiotherapy include esophagitis and radiation pneumonitis. However, it is important to be aware of uncommon post-radiotherapy complications such as bronchiolitis obliterans organizing pneumonia (BOOP). We report on two patients with carcinoma of the breast who developed an interstitial lung disease consistent with BOOP. BOOP responds to treatment with corticosteroids and the prognosis is generally good despite of the need for long-term administration of corticosteroids as relapses can occur during tapering of steroids. This report provides guidelines for the evaluation and treatment of patients with pulmonary infiltrates after radiotherapy.

Abstract
The aim of this study was to evaluate radiation-induced pulmonary abnormalities of breast cancer patients. Altogether 202 consecutive patients receiving postoperative radiotherapy entered the study. Plain chest radiographs taken at entry and 3, 6 and 12 months after radiotherapy were evaluated according to modified Arriagada classification. In addition, pulmonary symptoms were recorded. Supplementary high-resolution computed tomography (HRCT) was employed in a subgroup of patients (n?=?15). Plain radiographs were interpreted by a radiologist, and uncertain findings were re-evaluated by a radiologist together with a radiation oncologist. Grade 2 pneumonitis was the most common abnormality. The proportion of patients yielding a grade 2 finding was 22.5%, 28.1%, and 16.0% at three, six, and twelve months, respectively. There were 2 normal findings in HRCTscans, and 8 in plain radiographs of the same patients. Radiological lung abnormalities are common after radiotherapy, but they are usually reversible, and their significance for the patient's well-being is minor. No correlation between symptoms and lung or pleural reactions was seen.

Abstract
Although the beneficial effect of postoperative radiotherapy for breast cancer is well documented, this treatment may be related to a number of complications, which may affect patient quality of life and possibly survival. Among significant long-term irradiation sequelae are cardiac and lung damage, lymphoedema, brachial plexopathy, impaired shoulder mobility and second malignancies. The risk of these complications, particularly high with old, suboptimal irradiation techniques, has decreased with the introduction of modern technologies. In this paper, we review the contemporary knowledge on the toxicity of breast-cancer radiotherapy and discuss possible preventive measures.

Abstract
We report a case of lasting fever and cough with pulmonary infiltrates progressing 4 months after adjuvant radiotherapy following surgery for breast cancer. Chest radiography and computed tomography demonstrated alveolar opacities outside the irradiated pulmonary area. Laboratory data revealed neutrophilia and increased levels of C-reactive protein. Bronchoalveolar lavage fluid displayed increased lymphocyte counts, and transbronchial lung biopsy revealed histological patterns compatible with cryptogenic organizing pneumonia (COP). Corticosteroid therapy resulted in marked clinical improvement. From the histological and clinical findings, this case was judged to be a case of COP induced after radiotherapy for breast cancer, similar to those reported recently.

Abstract
BACKGROUND We previously reported that F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) response correlated strongly with survival after radical radiotherapy (RT)/chemoradiotherapy for non-small cell lung cancer (NSCLC). PET-response, survival and patterns of failure data are presented with long-term follow-up. METHODS Pre- and post-treatment FDG-PET scans were performed for 88 patients after concurrent platinum-based radical chemo/RT (n = 73) or radical RT alone (n = 15). PET responses were prospectively assessed as either complete metabolic response (CMR), partial metabolic response (PMR), stable metabolic disease (SMD), or progressive metabolic disease (PMD). RESULTS RT was 60 Gy in 30 fractions in 6 weeks. Follow-up PET was performed at a median of 70 days after treatment. PET responses were: CMR, n = 40 (45%); PMR, n = 32 (36%); SMD, n = 5 (6%) and PMD 11 (13%). Estimated median survival after follow-up PET was 23 months; median follow-up duration 35 months. One and 2 year survival after follow-up PET was 68% and 45%, respectively. Median survival for CMR and non-CMR patients was 31 and 11 months, respectively (p = 0.0001). One-year survival for CMR and non-CMR patients was 93% and 47%, respectively and 2 years survival was 62% and 30%, respectively. Excluding PMD patients, non-CMR patients had higher rates of local failure (HR 2.15, p = 0.009) and distant metastasis (HR 2.05, p = 0.041) than CMR patients. By last follow-up, 20 of 40 CR patients (50%) had PMD, with local failure (n = 8), distant metastasis (n = 2) or both (n = 10). CONCLUSIONS Attainment of CMR after radical RT/chemoRT for NSCLC bestows superior freedom from local and distant relapse; late local relapse is common.

Abstract
Radiation-induced lung disease (RILD) due to radiation therapy is common. Radiologic manifestations are usually confined to the lung tissue within the radiation port and are dependent on the interval after completion of treatment. In the acute phase, RILD typically manifests as ground-glass opacity or attenuation or as consolidation; in the late phase, it typically manifests as traction bronchiectasis, volume loss, and scarring. However, the use of oblique beam angles and the development of newer irradiation techniques such as three-dimensional conformal radiation therapy can result in an unusual distribution of these findings. Awareness of the atypical manifestations of RILD can be useful in preventing confusion with infection, recurrent malignancy, lymphangitic carcinomatosis, and radiation-induced tumors. In addition, knowledge of radiologic findings that are outside the expected pattern for RILD can be useful in diagnosis of infection or recurrent malignancy. Such findings include the late appearance or enlargement of a pleural effusion; development of consolidation, a mass, or cavitation; and occlusion of bronchi within an area of radiation-induced fibrosis. A comprehensive understanding of the full spectrum of these manifestations is important to facilitate diagnosis and management in cancer patients treated with radiation therapy.

Abstract
Iatrogenic respiratory disease is an important cause of patient morbidity and mortality. Clinical and radiologic findings are nonspecific and diagnosis can be difficult. Therefore, it is important for physicians to be familiar with the iatrogenic diseases for which their patients are at risk, as well as their common radiologic appearances. Causes of iatrogenic respiratory disease include drugs, transplantation, radiation, transfusion, or other miscellaneous therapies.

Abstract
A bronchosubcutaneous fistula is a communication between the subcutaneous tissues, the pleural cavity, and the bronchial system. It is a rare manifestation of primary pulmonary disease. The authors present a very unusual case of bronchosubcutaneous fistula that presented as subcutaneous emphysema after palliative radiation therapy for primary carcinoma of the lung.

Abstract
Fibrosis is a common outcome of chronic inflammation or injury. Pulmonary fibrosis may be the result of abnormal repair after an acute inflammatory response. The process of repair initiated by a tissue insult is largely a function of the activation of cells to produce important biological mediators such as cytokines, growth factors and chemokines, which orchestrate most aspects of the inflammatory response. Consequently, altered regulation of the production of inflammatory cell cytokines and chemokines after injury and repair likely contributes to the fibrosis. Our hypothesis is that chronic expression of specific chemokine and chemokine receptors during the fibrotic phase induced by thoracic irradiation may perpetuate the recruitment and activation of lymphocytes and macrophages, which may contribute to the development of fibrosis. Fibrosis-sensitive (C57BL/6) and fibrosis-resistant (C3H/HeJ) mice were irradiated with a single dose of 12.5 Gy to the thorax. Total lung RNA was prepared and hybridized using microarray analysis and RNase protection assays. At 26 weeks postirradiation, messages encoding the chemokines BLC (now known as Scyb13), C10 (now known as Scya6), IP-10 (now known as Scyb10), MCP-1 (now known as Scya2), MCP-3 (now known as Scya7), MIP-1gamma (now known as Scya9), and RANTES (now known as Scya5) and the chemokine receptors Ccr1, Ccr2, Ccr5 and Ccr6 were elevated in fibrosis-sensitive (C57BL/6) mice. In contrast, only the messages encoding SDF-1alpha (now known as Sdf1) and Ccr1 were elevated 26 weeks postirradiation in fibrosis-resistant (C3H/HeJ) mice. Our results point to the CC and CCR family members as the predominant chemokine responders during the development of fibrosis. These studies suggest that monocyte/macrophage and lymphocyte recruitment and activation are key components of radiation-induced fibrosis.

Abstract
Radiotherapy (RT) or radiochemotherapy is the treatment of choice for patients with medically or technically inoperable non-small cell lung cancer (NSCLC) localized to the primary site and regional lymph nodes. Radiation-induced damage has been recognized as a major complication in thoracic RT. The use of concurrent chemoradiation has been associated with an increase in acute and late toxicity. Amifostine (Ethyol) is an effective cytoprotective agent and also may have a role in protecting healthy lung tissue during radiation treatment. The purpose of these 2 clinical trials was to investigate whether daily pretreatment with amifostine could reduce the incidence of esophagitis, and acute and late lung toxicity without affecting the antitumor efficacy of the treatment. The first was a phase III randomized trial of 146 patients with locally advanced lung cancer. All patients received conventional RT to a total of 55 to 60 Gy, and they were assigned randomly to pretreatment with 340 mg/m(2) of amifostine (A). Acute and late toxicities were graded according to the Radiation Therapy Oncology Group (RTOG) grading system from grades 0 to 4. Ninety-seven patients were evaluated 2 months post-RT for the incidence of pneumonitis; 43% (23 of 53) of patients in the RT arm and 9% (9 of 44) in the A plus RT arm experienced grade > or = 2 pneumonitis (P <.001). Forty-nine percent (26 of 53) of patients in the RT arm and 16% (7/44) in the A plus RT arm showed changes that were representative of grade > or = 2 lung damage in the computed tomography (CT) scan. Fibrosis was present in 53% (19 of 36) of patients receiving RT versus 28% (9 of 32) in the A plus RT arm at 6 months (P < 0.05). The incidence of esophagitis grade > or = 2 during week 4 was 42% (31 of 73) in the RT arm versus 4% (3 of 73) in the A plus RT arm (P <.001). Among 97 patients evaluable for response 2 months after RT, complete or partial responses were present in 76% (40 of 53) of patients in the RT arm and 75% (33 of 44) in the A plus RT arm (P = 1.0). The second trial was a phase II randomized study of 45 patients with NSCLC. All patients had received platinum-based induction chemotherapy before being referred for conventional radiation treatment with or without A; a total dose of 55 to 60 Gy was administered at the primary site. Acute and late toxicities were evaluated and graded according the RTOG criteria from grades 0 to 4. Forty-five patients were evaluable for response 2 months after RT. Complete or partial responses were achieved in 78% (18 of 23) of patients in the RT arm and 82% (18 of 22) in the A plus RT arm (P =.278). By week 5, 74% (17 of 23) of patients in the RT group versus 36% (8 of 22) in the A plus RT group experienced grade > or = 2 esophagitis. (During the follow-up period, pulmonary toxicity was evaluated by CT scan.) Three months after RT, 65% (15/23) of patients in the RT group and 32% (7 of 22) in the A plus RT group presented with grade > or = 2 pneumonitis (P =.038). Amifostine reduces the incidence of acute and late radiation-induced toxicities.

Abstract
PURPOSE To evaluate the relationship between physician-identified radiographic fibrosis, lung tissue physical density change, and radiation dose after concurrent radiation therapy and chemotherapy for limited small cell lung cancer. MATERIALS AND METHODS Fibrosis volumes of different severity levels were delineated on computed tomography (CT) images obtained at 1-year follow-up of 21 patients with complete response to concurrent radiation therapy and chemotherapy for limited small cell lung carcinoma. Delivered treatments were reconstructed with a three-dimensional treatment planning system and geometrically registered to the follow-up CT images. Tissue physical density change and radiation dose were computed for each voxel within each fibrosis volume and within normal lung. Patient responses were grouped per radiation and chemotherapy protocol. RESULTS A significant correlation was noted between fibrosis grade and tissue physical density change and fibrosis grade. For doses less than 30 Gy, the probability of observing fibrosis was less than 2% with conventional fractionation and less than 4% with accelerated fractionation. Physical lung density change also showed a threshold of 30-35 Gy. For doses of 30-55 Gy and cisplatin and etoposide (PE) chemotherapy, fibrosis probability was 2.0 times greater for accelerated fractionation compared with conventional fractionation (P < .005) and was correlated to increasing dose for both fractionation schedules. CONCLUSION Lung tissue physical density changes correlated well with fibrosis incidence, and both increased with increasing dose greater than a threshold of 30-35 Gy. With concurrent PE chemotherapy, fibrosis probability was twice as great with accelerated fractionation as with once-daily fractionation.

Abstract
PURPOSE This multicenter trial investigated whether daily pretreatment with amifostine (A) could reduce the incidence of acute and late lung toxicity and esophagitis without affecting antitumor efficacy of radiation in advanced lung cancer. PATIENTS AND METHODS Radiotherapy (XRT) patients (n = 146) received a daily fraction of 2 Gy/5 days/week to a total of 55-60 Gy +/- amifostine 340 mg/m(2) administered daily 15 min before irradiation. Acute and late toxicities were graded from 0 to 4 according to the Radiation Therapy Oncology Group/European Organization for the Research and Treatment of Cancer system. RESULTS Ninety-seven patients were evaluated 2 months post-XRT for the incidence of pneumonitis; 43% (23/53) of patients in the XRT arm and 9% (4/44) in the A + XRT arm experienced > or = Grade 2 pneumonitis (p < 0.001) [corrected]. Forty-nine percent (26/53) of patients in the XRT arm and 16% (7/44) in the A+XRT arm demonstrated changes representative of > or = Grade 2 lung damage (p < 0.001). At 6 months, fibrosis was present in 53% (19/36) receiving XRT vs. 28% (9/32) receiving A+XRT (p < 0.05). Incidence of esophagitis > or = Grade 2 during Week 4 was 42% (31/73) in the XRT arm vs. 4% (3/73) in the A+XRT arm (p < 0.001). Among 97 patients evaluable for response 2 months after XRT, complete or partial response was present in 76% (40/53) of patients in the XRT arm and 75% (33/44) in the A+XRT arm (p = 1.0). CONCLUSION Amifostine reduces the incidence of pneumonitis, lung fibrosis, and esophagitis in radiotherapy patients with lung cancer without compromising antitumor efficacy.

Abstract
Airspace filling process is characterized on CT by the presence of one or more fairly homogeneous areas of consolidation with little or no volume loss. The consolidation may be segmental, subsegmental, lobular, or acinar (10 mm or less in diameter). Poorly defined centrilobular nodules may be associated. The margin of the consolidation usually is poorly defined except in the areas in which the consolidation abuts the pleura. Air-containing bronchi or bronchioles (CT air bronchograms or air bronchiolograms) are seen frequently. Many diseases can present with alveolar filling disorders. Because the HRCT findings overlap among various alveolar filling disorders, it may be impossible to make a definite diagnosis with HRCT findings alone. Integration of HRCT findings including disease pattern and distribution and time factors including evolution and resolution of the disease, however, may enable to narrow differential diagnosis of alveolar filling diseases. Furthermore, clinical and laboratory findings also may provide helpful clues to reach a reasonable diagnosis. The role of HRCT in alveolar filling disorders is not limited to diagnosis. HRCT also plays a useful role in determining the extent of disease and in identifying accompanying abnormalities, and complications of the primary disease.

Abstract
PURPOSE To prospectively study the effects of loco-regional radiotherapy in women with breast cancer. METHODS AND MATERIALS Thirty consecutive patients with breast resection underwent clinical, lung function, radiographic, and thoracic high-resolution computed tomography evaluation before and at 1, 3, 6, and 12 months after adjuvant radiotherapy. Chemotherapy was also administered to 15 patients. RESULTS Nineteen patients reported mild respiratory symptoms at 1 month, which resolved completely at 6 months after radiotherapy. Opacities were present on 80% of chest radiographs and in all patients on high-resolution computed tomography by 3 months. These opacities became compact and persisted on high-resolution computed tomography at 12 months. Lung function indices, including FEV1, FVC, TLC, and DLCO, progressively declined after radiotherapy, and was irreversible at 12 months (p < 0.05). Patients who received chemotherapy did not have significantly different lung function indices compared with their counterparts at all time points (p > 0.05). CONCLUSIONS Our results have shown that adjuvant loco-regional radiotherapy, a common practice in breast cancer treatment, is associated with irreversible reduction in lung function parameters. These changes are accompanied by radiological evidence of persistent lung injury. Further studies should be performed to evaluate the incidence and long-term pulmonary sequelae of current treatment for breast cancer.

Abstract
The biological effects of inhaled beta-particle-emitting radionuclides are not well known. The non-neoplastic diseases induced by an inhaled, relatively insoluble form of cerium-144 ((144)Ce) were studied in beagle dogs exposed to graded activity levels of (144)Ce in fused aluminosilicate particles by a single, brief inhalation exposure and observed for their life span. The initial lung burdens (ILBs) achieved ranged from 0.000093-7.6 MBq (144)Ce/kg body weight. The (144)Ce was retained in the lung with an effective half-life of about 190 days. Significant (144)Ce was translocated to the tracheobronchial lymph nodes, and the concentration exceeded that of the lung at about 400 days after inhalation exposure. Significant radiation doses were delivered to the lung and tracheobronchial lymph nodes and to the heart adjacent to the tracheobronchial lymph nodes. Radiation pneumonitis was the predominant non-neoplastic disease. The dose response for radiation pneumonitis indicated that an ILB of 1.4 MBq/kg would cause death from radiation pneumonitis in 50% of the exposed dogs. This ILB resulted in a pulmonary dose to death of about 350 Gy. The tracheobronchial lymph nodes developed lesions in dogs with ILBs lower than those causing radiation pneumonitis. The overall results of this study, however, showed that (144)Ce, inhaled in an insoluble form, did not cause any unique or inexplicable biological effects in dogs or cause effects at unusually low doses that might call current radiation protection guidelines into question.

Abstract
To assess the bronchoscopic and lung function changes induced by preoperative radiochemotherapy (30 Gy radiation and 5-fluorouracil) in patients with proximal esophageal cancer, we prospectively compared the findings in 77 consecutive patients before and after the therapy. All patients completed the radiochemotherapy protocol; toxicity was minimal. Sixty-four patients underwent surgery, 48 had total gross removal of disease, and six had a complete histologic response. Of the 13 patients who developed apparent direct macroscopic signs of tumor invasion into the airways during therapy, histologic proof of cancer was obtained in only one of the abnormalities. Bronchoscopy was falsely negative in six patients in whom airway invasion of the cancer was found at surgery. Neoadjuvant therapy led to no systematic changes in the appearance of the uninvolved tracheal mucosa; microscopically, an increase in postinflammatory changes, hyperplasia, and metaplasia was found. There was no significant change in the values of lung function parameters after the therapy. No patient developed symptoms suggestive of radiation-induced lung changes, although in one of them, subtle radiologic features consistent with radiation pneumonitis were found. No patient died of postoperative pulmonary complications. The interpretation of bronchoscopy in the assessment of airway invasion of esophageal cancer after radiochemotherapy is more difficult than at baseline staging; the positive predictive value of macroscopic abnormalities without microscopic proof of cancer is low, and even with extensive sampling for histology and cytology, the procedure was falsely negative in 9.4%. Neoadjuvant therapy did not induce radiation pneumonitis or changes in lung function that could be of concern at the following operation.

Abstract
AIMS To document serial high resolution computed tomography (HRCT) features of lung injury after 3-field radiotherapy for breast cancer. MATERIALS AND METHODS Thirty women who received opposing tangential chest wall and supraclavicular field (SCF) irradiation after breast surgery were recruited. Thoracic HRCT was performed before and at 1, 3, 6 and 12 months after radiotherapy (RT). Lung injury at 3 months was quantified by applying a scoring system to each HRCT section. Findings were correlated with spirometric lung function tests. RESULTS There was HRCT evidence of lung injury in 27 (90%) women at 1 month and in all 30 patients at 3 months. Spirometric lung function declined post-RT (P < 0.05), correlating with an increased SCF acute lung injury score at 3 months [r = -0.54 and -0.46, P = 0.01 and 0.03 for forced expiratory volume in 1st (FEV(1)) and forced vital capacity (FVC), respectively]. Lung injury on HRCT progressed from ground glass opacification at 1 month to nodular consolidation (3 months), increasing linear densities (6 months), and finally to residual subpleural linear and dense opacities (12 months). CONCLUSION There is a high incidence of lung injury associated with 3-field radiotherapy for breast cancer, with concurrent SCF irradiation increasing the risk of lung damage and functional impairment. A characteristic sequence of HRCT changes is seen in most patients receiving this type of radiotherapy.Ooi, G. C. (2000). Clinical Radiology55, 817-824.

Abstract
BACKGROUND Growing evidence indicates that unilateral lung irradiation for breast cancer may "prime" the development of migratory lung infiltrates with histologic features of bronchiolitis obliterans organizing pneumonia. OBJECTIVE Our purpose was to evaluate the cytologic and immunocytologic features of bronchoalveolar lavage in this condition. METHODS We analyzed the profile bronchoalveolar lavage cell differentials and lymphocyte subpopulations of 11 women with bronchiolitis obliterans organizing pneumonia syndrome after radiation therapy for breast cancer in comparison to 9 healthy women. RESULTS The bronchoalveolar lavage analysis demonstrated a significant increase in the percentage of lymphocytes (36.7% +/- 5.4% vs 8.6% +/- 1.1%, P =.0002), neutrophils (3.8% +/- 1.2% vs 0.6% +/- 0.2%, P =.005), eosinophils (2.4% +/- 1% vs 0.3% +/- 0.1%, P =.01), and mast cells (1.4% +/- 0.6% vs 0.1% +/- 0.02%, P =.05) with a significant decrease in the percentage of macrophages (56.1% +/- 6% vs 90.3% +/- 1.4%, P =.0002) in patients with bronchiolitis obliterans organizing pneumonia compared with the control subjects. The percentage of CD3(+) cells was significantly increased in patients with bronchiolitis obliterans organizing pneumonia (93.7% +/- 1.3% vs 70.9% +/- 4%, P =.0004), with a significant decrease in CD4(+) cells (32.7% +/- 4.7% vs 55.4% +/- 2. 6%, P =.002) and a significant increase in CD8(+) cells (61.2% +/- 4. 8% vs 37.5% +/- 2.9%, P =.003) in comparison to control subjects. The CD4/CD8 ratio was significantly reduced in patients with bronchiolitis obliterans organizing pneumonia compared with control subjects (0.6% +/- 0.1% vs 1.5% +/- 0.1%, P =.001). CONCLUSION These data add to the view that unilateral lung irradiation for breast cancer may "prime" the development of a syndrome quite similar to idiopathic bronchiolitis obliterans organizing pneumonia.

Although radiologic findings in radiation-induced lung disease are well described in the literature, the influence exerted on these findings by different radiation methods is not well understood. Radiation treatment of non-small cell lung cancer varies depending on the location and extent of disease. Irradiation with oblique beam angles results in unusual distribution of radiation-induced lung disease. Small cell lung cancer is treated with irradiation concurrent with or following chemotherapy, and portal arrangements are controversial. In breast cancer, use of tangential beam portals may induce radiation pneumonitis or fibrosis at the peripheral lung anterolaterally. Use of supraclavicular portals may produce lesions in the lung apex that appear similar to pulmonary tuberculosis. In esophageal cancer, radiation portals with a 5-6-cm margin above and below the tumor are generally recommended, and computed tomography (CT) frequently demonstrates radiation-related lung damage adjacent to the mediastinum. In mediastinal tumors, the mantle field includes all the major lymph node regions above the diaphragm. Radiation pneumonitis varies from minimal to extremely marked change in the paramediastinal areas and in both apices. CT is more sensitive to radiation-induced lung disease than chest radiography and demonstrates related changes earlier. Furthermore, it more clearly depicts the precise distribution and pattern of disease. Familiarity with the imaging findings in radiation-induced lung disease produced by different radiation methods will help radiologists interpret abnormalities seen at chest radiography and CT in affected patients.

Abstract
PURPOSE The purpose of this work was to demonstrate the variety of causes of crazy-paving appearance (CPA) on high resolution CT (HRCT). METHOD To identify cases exhibiting CPA (ground-glass opacity with superimposed interlobular septal thickening and intralobular interstitial thickening) on HRCT, we prospectively searched for them over a period of 29 months. RESULTS We identified 10 cases of CPA on HRCT, including 4 Pneumocystis carinii pneumonia, 1 alveolar proteinosis, 1 usual interstitial pneumonia, 1 pulmonary hemorrhage, 1 acute radiation pneumonitis, 1 adult respiratory distress syndrome, and 1 drug-induced pneumonitis. CONCLUSION CPA can result from a variety of diseases. When we encounter CPA on HRCT, clinical information is necessary for differentiation of these entities.

Abstract
Reports of bronchiolitis obliterans organizing pneumonia (BOOP) occurring in women after radiation therapy for breast cancer have suggested that radiation to the lung could participate in the development of BOOP. We now describe the clinical, radiographic, functional, and bronchoalveolar lavage characteristics of this syndrome in a series of 15 patients reported to the Groupe d'Etudes et de Recherche sur les Maladies "Orphelines" Pulmonaires (GERM"O"P) in France. All 15 women (60 +/- 6 yr of age) fulfilled the following inclusion criteria: (1) radiation therapy to the breast within 12 mo, (2) general and/or respiratory symptoms lasting for at least 2 wk, (3) lung infiltrates outside the radiation port, and (4) no specific cause. The patients presented with fever, nonproductive cough, mild dyspnea, and peripheral alveolar opacities on chest radiograph with a characteristic migratory pattern. In five patients, BOOP was found at lung pathologic analysis. In all the patients dramatic improvement was obtained with corticosteroids, but relapses occurred in 12 patients while tapering or after stopping corticosteroids. This report demonstrates that a characteristic BOOP syndrome may occur after radiation therapy to the breast, including tangential radiation to the lung, thus suggesting that radiation therapy may prime the development of BOOP.

Abstract
BACKGROUND AND PURPOSE Retrospective evaluation of the incidence of lethal pulmonary complications (LPC) with special emphasis on interstitial pneumonia (IP) in a large group of patients homogeneously treated with hyperfractionated total body irradiation (HTBI) before autologous bone marrow transplantation (ABMT) or peripheral blood stem cell transplantation (PBSCT) for hematological malignancy. The factors influencing IP are discussed. MATERIALS AND METHODS Of 260 patients (maximum follow-up 137 months) that were treated with ABMT or PBSCT for hematological neoplasms between 1982 and 1994, 209 patients received HTBI and could be evaluated with respect to lethal pulmonary complications and especially lethal interstitial pneumonia. For most patients (n = 155), the HTBI dose was 14.4 Gy (lung dose 9-9.5 Gy) given in 12 fractions over 4 days. Twenty-one patients received a total dose of > or =15 Gy with pulmonary doses of 9-10.5 Gy. RESULTS The actuarial overall 5-year survival for all 209 patients evaluated was 44 +/- 4%, enabling valid evaluation with respect to lethal pulmonary toxicity. The actuarial incidence of all LPC during the first year was calculated as being 8 +/- 2%. The actuarial incidence of lethal IP is certainly lower and was estimated to be between 3 and 5% for all patients. The overall treatment-related mortality was 12% in 188 patients that received a total dose of <15 Gy and 24% among the patients treated with a total dose of > or =15 Gy. CONCLUSION ABMT/PBSCT, like other transplant modalities without significant graft versus host disease (GvHD), has a low transplant-related mortality, a very small rate of overall LPC and a low incidence of lethal IP after HTBI. Doses up to 14.4 Gy with lung doses of 9-9.5 Gy can be administered safely. For total doses of > or =15 Gy with lung doses of 9-10.5 Gy, the risk of serious transplant-related complications cannot yet be finally assessed but such higher doses should be considered with caution because of the possibility of increasing toxicity in organs other than the lung.

Abstract
Many uranium miners have been disabled by and died of pulmonary fibrosis that was not recognized as an occupational disease. A review of animal studies, complications from whole body irradiation, pulmonary function, and mortality studies of uranium miners led us to suspect radiation-induced chronic diffuse interstitial fibrosis in miners who had inhaled excessive radon progeny. A selected group of uranium miners (22) with severe respiratory disease (but no rounded nodules in chest films) were studied. Lung tissue from five disclosed severe diffuse interstitial fibrosis, with "honeycomb lung" in all. Some also had small anthrasilicotic nodules and birefringent crystals. Although quartz crystals probably contributed, we concluded that the predominant injurious agent in these cases was alpha particles from radon progeny. This disease, after a long latent period, usually results in pulmonary hypertension, shortness of breath, and death by cardiopulmonary failure.

Abstract
PURPOSE Clinical observations often reveal individual differences in the severity of lung fibrosis after definitive radiation therapy for lung cancer. Recent experimental studies suggest that the risk of developing lung fibrosis may be genetically controlled. The present study was undertaken to examine the magnitude of individual variation in the incidence and severity of lung fibrosis in a well-defined patient population treated by concurrent chemoradiation for limited small-cell lung carcinomas (LSCLC). MATERIALS AND METHODS Between 1989 and 1994, 56 patients with LSCLC were enrolled in one of two controlled prospective studies of concurrent chemotherapy and concomitant conventional (45 Gy in 25 fractions q.d. over 5 weeks) or accelerated (45 Gy in 30 fractions b.i.d. over 3 weeks) radiotherapy. Chemotherapy consisted of cisplatin and etoposide (PE) or PE plus ifosfamide and mesna (PIE). Of the 56, a group of 25 patients who had serial computerized tomography (CT) examinations of the chest and were deemed to have unequivocal radiographic complete responses were selected for this study. The severity of lung fibrosis was recorded for each patient from the CT images using an arbitrary scale (0 to 3) at 1 year after treatment. Radiographic fibrosis scores were recorded on 1-3 CT slices in 3 different dose-areas (20-30 Gy; 30-40 Gy; and >40 Gy) that were defined using the corresponding CT slices from the patient's CT treatment plan. Of these patients, 23 (92%) had at least 2 slices scored; 11 patients had all 3 slices scored. RESULTS Among the clinical and treatment parameters investigated (including type of chemotherapy), only total dose and fractionation schedule were identified as significant and independent determinants of lung fibrosis. Radiographic fibrosis scores were higher in high-dose areas and among patients treated with the accelerated schedule. Using a fit of the proportional odds (PO) model based on the total dose and fractionation schedule, fibrosis score residuals were calculated for each patient. The residual for each score is defined as the difference between the observed and expected score based on the dose and treatment schedule received. Average residuals varied significantly among patients (p = 0.005, Kruskal-Willis test). Using a modified version of the PO model, the coefficient of variation in patient heterogeneity was estimated to be 10.1% (95% confidence interval: 6.2-14.9%). Inclusion of the heterogeneity factor, in addition to total dose and fractionation schedule, improved the fit of the PO model to an extremely high level of significance (p < 10(-7)). CONCLUSIONS Our data indicate that the risk and severity of lung fibrosis analyzed radiographically on CT images increases with total dose and with the use of an accelerated radiation schedule, for patients treated with chemoradiation for small-cell lung cancer. There was also demonstrable patient-to-patient heterogeneity, suggesting that the risk of lung fibrosis is strongly affected by inherent factors that vary among individuals.

Abstract
CT-assessed density changes in lung tissues were measured in 22 disease-free breast cancer patients 4 years after completion of radiation therapy. All patients had previously undergone similar CT-examinations before treatment, 3 months, and 9 months after radiotherapy. In patients with visible areas of increased lung density at earlier CT-examinations a decrease of focal findings was observed at 4 years. In patients without focal findings, an increase in density relative to that before therapy was observed. The difference between the mean lung density values among those with visible radiological findings and those without was statistically significant both at 3 and 9 months after therapy. However, this difference did not persist at 4 years. These results may indicate a 2-phase development of radiation-induced lung damages--an acute phase and a late phase; the late phase emerging slowly, and in this study detectable 4 years after completion of radiation therapy.
