This synthesis of the literature on radiotherapy for lung cancer is based on 80 scientific articles, including 2 meta-analyses, 29 randomized studies, 19 prospective studies, and 21 retrospective studies. These studies involve 28172 patients. Basic treatment for limited-stage small cell lung cancer (SCLC), is chemotherapy. Addition of radiotherapy to the primary tumor and mediastinum reduces local recurrence, prolongs long-term survival, and is often indicated. Current, and future, studies can be expected to show successive improvements in results for SCLC by optimizing the combination of radiotherapy and chemotherapy. Should these treatments be given simultaneously or sequentially, and in which order? Which fractionation is best? Probably, no change in resource requirements for radiotherapy will be necessary, with the possible exception of changes in fractionation. Surgery constitutes primary treatment for nonsmall cell lung cancer (NSCLC) stages I and II. Radiotherapy may provide an alternative for patients who are inoperable for medical reasons. The value of radiotherapy following radical surgery for NSCLC remains to be shown. It is not indicated based on current knowledge. For NSCLC stage III, radiotherapy shrinks tumors and prolongs survival at 2 and 3 years. Whether it influences long-term survival after 5 years has not been shown. Considering the side effects of treatment, one must question whether limited improvements in survival motivate routine radiotherapy in these patients. Earlier attempts to add chemotherapy to radiotherapy to improve treatment results of NSCLC have not yielded convincing results. Several studies are currently on-going. Prophylactic cranial irradiation (PCI) greatly reduces the risk for brain metastases from SCLC. However, it has little influence on survival. Many treatment centers give PCI to SCLC patients who have achieved complete remission. This practice may be questioned since PCI is associated with serious complications. PCI is not indicated in patients with NSCLC. In SCLC, where the disease is extensive, only palliative radiotherapy is appropriate. Radiotherapy is an important treatment alternative in special palliative situations involving severe cough, severe bleeding, pain, pulmonary obstructions, and vena cava superior syndrome. In these situations, good results may be achieved with few fractions.

Approximately one half of prescribed radiotherapy is given for palliation of symptoms due to incurable cancer. Distressing symptoms including pain, bleeding, and obstruction can often be relieved with minimal toxic effects. Painful osseous metastasis is common in oncologic practice. Ninety percent of patients with symptomatic bone metastases obtain some pain relief with a lowdose, brief course of palliative radiotherapy. One half of the responding patients may experience complete pain relief. A single dose of 800 cGy in the setting of painful bone metastasis may provide pain control comparable to more protracted treatment at a higher dose of radiation. Patients with lytic disease in weight-bearing bones, particularly in the presence of cortical destruction, should be considered for prophylactic surgical stabilization of their condition. Routinely a brief, fractionated course of radiotherapy is given postoperatively. Pain due to multiple bone metastases uncontrolled by analgesics can be managed with single doses of halfbody irradiation. Doses of 600 cGy delivered to the upper half-body (above the umbilicus) and 800 cGy to the lower half-body (from the umbilicus to the middle of the femur) will provide some pain relief in 73% of patients. Half-body techniques have been investigated as prophylactic treatment, as a complement to local-field irradiation, and as fractionated rather than singledose therapy. Although intravenous administration of strontium 89 has been associated with myelosuppression, this treatment has been shown (a) to relieve pain due to bone metastasis and (b) to delay development of new painful sites. Recent data from phase III trials demonstrated that bisphosphonates have a role in reducing skeletal morbidity due to bone metastasis. Bone pain was reduced, and the incidence of pathologic fracture and the need for future radiotherapy was decreased. Radiotherapy relieves clinical symptoms in 70% to 90% of patients with brain metastases. Brief treatment schedules (e.g., 2000 cGy in five fractions over 1 week) are as effective as more prolonged therapy. Patients with solitary brain metastasis and no extracranial disease or controlled extracranial disease should be considered for surgical resection, because phase III data indicate enhanced survival with such an approach. Whole-brain radiotherapy is routinely administered postoperatively. A phase III study is examining the impact of accelerated fractionated doses of radiotherapy (two treatments per day) on survival of patients with brain metastases. Stereotaxic radiosurgical treatment is becoming increasingly available and permits delivery of radiation to metastatic intracranial tumor with minimal exposure of normal surrounding brain This treatment is most commonly used at the time of a solitary recurrence of disease in patients who previously received whole-brain radiotherapy. A role for this modality in newly diagnosed brain metastases remains to be defined. Chest symptoms are common in patients with locally advanced lung cancer and are effectively palliated with one 1000 cGy or two 850 cGy one fraction doses of radiation to the thoracic inlet and mediastinum. Chest pain and hemoptysis are more effectively palliated than cough and dyspnea. In patients with stage III cancer there is no compelling evidence that radiotherapy confers a survival advantage, and it may be reasonable to administer thoracic radiotherapy only when the patient has significant symptoms and the goal is to achieve control of these symptoms. Approximately 75% of the cases of superior vena cava syndrome are due to lung cancer, and small-cell lung cancer is the most common histologic type. A histologic diagnosis should be obtained before treatment is started, because detection of lymphoma or small-cell carcinoma would necessitate systemic therapy. Eighty percent of the patients with vena cava syndrome due to malignant disease achieve symptom relief with a brief, fractionated, palliative course of rad

Interleukin (IL) 2 plays an important role in enhancing the immune response, whereas IL-4 has pluripotent activities which include affecting immune function. Preclinical data suggest that the combination might have enhanced immunomodulatory activity. In this Phase I trial in patients with advanced solid tumors, both IL-2 and IL-4 were given by separate s.c. injections simultaneously daily, 5 days in a row, Monday through Friday, for 3 consecutive weeks, followed by a 1-week break from treatment. Cycles could be repeated. The dose of IL-2 was kept constant at 9 x 10(6) IU/m2/injection while the dose of IL-4 was escalated beginning at 100 microgram/m2/injection and increasing by 100-microgram/m2 increments to a planned level of 400 microgram/m2/injection. Sixteen patients were entered in this study, with one patient being ineligible because of the presence of brain metastases. Of the 15 eligible patients, there were 14 males and 1 female, with a median age of 54 (range, 38-67) years and initial performance status of 0 in 5 patients and 1 in 10 patients. Patients were treated at levels of up to 300 microgram/m2/injection of IL-4 before the study was closed due to withdrawal of the drug by the manufacturer. The most commonly observed toxicities were fatigue, fever and chills, local reaction, nausea/vomiting and anorexia, headache and nasal stuffiness, and coughing, sometimes with the production of clear white sputum, more common in smokers. Duodenal ulcers occurred in one patient and one patient had grade 4 cardiac toxicity consisting of an asymptomatic minimal elevation of the creatinine phosphokinase MB isoenzyme (CPK-MB). Grade 3 hyponatremia occurred in two patients, and elevated liver function tests and creatinine occurred but were not dose limiting. Eosinophilia of unknown significance occurred in all patients. There were statistically significant elevations in absolute numbers of most T-cell subsets examined, without changes in circulating B cells. No antibodies to the IL-4 were found after one cycle. One patient with renal cell carcinoma showed a significant decrease in tumor burden after one cycle of treatment. Because of the IL-4 withdrawal, the maximum tolerated dose for this combination of drugs given by the route and schedule used here was not determined and will require additional testing. Subcutaneous IL-2 and IL-4 given simultaneously show important immunomodulatory and antitumor effects and should be tested further in cancer patients.

We describe two new resected cases of primary pulmonary hemangiopericytoma and the review of cases published in the period 1954-2002. The first patient has a large pulmonary mass of the right apex revealed by scapular pain. The right upper lobectomy with free margins reveals hemangiopericytoma. Pelvic and pulmonary metastases appear two years after surgery, treated by two series of chemotherapy without clinical response. After acute nephrotoxicity controlled by hemodialysis, the patient dies with distant metastases three years and an half after thoracotomy. The second patient develops dry cough and thoracic pain with discovery of a cavitary mass in the right pulmonary field. Fine needle aspiration cytology suggests a mesenchymatous lesion. Three months after extended pneumonectomy, the intrathoracic tumour relapses and regresses partially under chemotherapy. Femoral and brain metastases are irradiated. The patient dies 22 months after thoracotomy. Histology and immunohistochemistry of both tumours closely related to solitary fibrous tumour confirm malignant hemangiopericytoma. Primary pulmonary hemangiopericytoma is rare and may be benign or malignant. Radical resection is the best treatment. Chemotherapy and radiotherapy may improve the prognosis. Compared with lung cancer, the tumour is a slow growing mass, often voluminous, with delayed symptoms, very few lymph node dissemination, rare brain metastasis, more frequent cutaneous or retroperitoneal dissemination, often after long-term and requiring indeed a 10 to 20 years follow-up.

A 25-year-old man who suffered from cough, sputum, and swelling of left scrotal contents was admitted to our hospital. We found testicular choriocarcinoma with multiple lung, liver, and brain metastases. The patient received 5 courses of VIP therapy (cisplatin, etoposide, ifosfamide) and 1 course of high-dose chemotherapy (carboplatin, etoposide, cyclophospamide) with peripheral blood stem cell transplantation. One year later, the patient underwent surgery for resection of lung metastasis after 1 course of chemotherapy (cisplatin, etoposide). Pathological diagnosis showed a remnant of choriocarcinoma. Three years and three months after surgery, no recurrence of the choriocarcinoma has been found.

The noise produced by oscillatory movements of secretions in the oropharynx, hypopharynx, and trachea during inspiration and expiration in unconscious terminal patients is often described as "the death rattle." The secretions are produced by the salivary glands and bronchial mucosa. These patients are usually too weak to expectorate or swallow the migrating secretions. Sputum usually only accumulates in these areas if there is a significant impairment of the cough reflex, as in deep coma or near death. Reported incidence of death rattle in terminal patients varied between 6 and 92%. Death rattle was most commonly reported in patients dying from pulmonary malignancies, primary brain tumors, or brain metastases, and predicts death within 48 hours in 75% of the patients. After withdrawal of artificial ventilation from the intensive care unit, excessive respiratory secretion resulting in a rattling breathing during the last hours of life is not uncommon, especially not in pulmonary and neurological patients. The distressing experience and negative influence in the bereavement process indicates an ethical demand to treat this symptom from the perspective of others merely than that of the patient.

A 66-year-old female complained of cough, and was referred to our hospital. Chest radiography and computed tomography (CT) showed a tumor mass near the right hilum and atelectasis of the middle lobe. Bronchoscopy revealed a whitish polypoid tumor obstructing the middle lobe bronchus. Histology by punch biopsy suggested adenocarcinoma Right upper and middle lobectomy was performed, due to the direct invasion of the tumor from the middle lobe to the upper lobe. Histological findings showed adenocarcinoma comprised of spindle cell component, finally diagnosing as pleomorphic carcinoma of the lung. After the operation, systemic chemotherapy, including paclitaxel and carboplatin was performed. About 42 months after operation, the patient died of multiple brain metastases.

NUT midline carcinoma (NMC) is a poorly differentiated tumor typically driven by a t(15;19) rearrangement leading to a NUT fusion event. This rare and uniformly fatal tumor arises in multiple organ sites; however the clinical, radiographic, and pathologic characteristics of primary pulmonary NMC are poorly defined. We identified eight cases of primary pulmonary NMC in our consult practice over 4 years and, using a NUT immunohistochemistry screen, retrospectively identified one additional case from 166 (0.6%) consecutive in-house biopsies of lung carcinomas lacking glandular differentiation. Eight cases had available clinical and radiographic data and shared a remarkable degree of similarity. The median age at presentation was 30 (range 21-68). Six patients had little or no smoking history. All complained of 1 to 3 months of cough at presentation. Computed tomography scans showed a large, centrally located primary mass with confluent involvement of mediastinal lymph nodes, pleural disease, and sparing of the contralateral lung. Lytic bone metastases were common but brain metastases were absent in all cases. Pathologically, all cases showed primitive-appearing round to epitheloid cells growing in nests and sheets. All tumors expressed keratin, p63 or p40, and NUT protein. Eight cases had a fluorescence in situ hybridization-proven BRD4-NUT or BRD3-NUT rearrangement; one case was presumed to have a NUT-variant fusion event. Median overall survival was 2.2 months. Despite the rarity of primary pulmonary NMC, it is important to recognize this entity to counsel patients regarding outcome and to identify candidates for targeted BRD inhibitors currently in clinical trials.

Primary melanoma of the lung is an extremely rare clinical entity. We found only 32 cases reported in literature, and in two of these multiple brain metastases were present. We describe a case of primary lung melanoma with brain and skin metastases that presented with an initial clinical diagnosis of pneumonia. A 55-year-old white man presented with cough productive of dark sputum and fever. A chest x-ray showed a right lung infiltration. After failure to respond to usual treatment for pneumonia, bronchoscopy examination and CT scan revealed a right pulmonary mass. The CT-guided biopsy confirmed a diagnosis of malignant melanoma. The primary lung origin of the tumor was demonstrated by the characteristic junctional pattern of melanoma cells. Further evaluation revealed metastases in the brain and in skin. Primary lung melanoma is an uncommon neoplasm that may be confused with more conventional types of lung cancer. Careful interpretation of histopathological information in correlation with all other clinical, laboratory and imaging studies may be needed to establish a diagnosis. Evaluation for metastases should include looking at the eyes, brain, skin. Due to the small number of cases reported in literature, there is no experience on the management and the prognosis of the disease.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 54-year-old man with a former 15-pack-year smoking history presents with cough and dyspnea. Initial work-up with imaging demonstrates a right suprahilar mass measuring 4.7 cm as well as several enlarged hilar and ipsilateral mediastinal lymph nodes. Bronchoscopy with biopsy reveals adenocarcinoma consistent with a lung primary. Staging with positron emission tomography/computed tomography (PET/CT) reidentifies the primary mass and lymph nodes and shows several PET-avid bone metastases. Brain magnetic resonance imaging (MRI) demonstrates a 1.6-cm right parietal mass with mild vasogenic edema and four additional brain metastases measuring 4 to 9 mm in size. Molecular testing is positive for an anaplastic lymphoma kinase (ALK) gene rearrangement using fluorescence in situ hybridization and negative for EGFR, ROS1, RET, BRAF, KRAS, and other oncogenes. The patient denies any neurologic symptoms and has no significant findings on neurologic exam. He is referred to you for management options for newly diagnosed stage IV (T2aN2M1b) lung adenocarcinoma.
