To investigate the chance of discovery of metastatic lung tumors and the five-year survival rates of patients undergoing surgical resection, we followed 99 patients who underwent initial surgical treatment at our hospital between 1979 and 1996. With regard to primary organs or sites, 32 patients had rectal cancer, 27 patients had breast cancer, 19 patients had colon cancer and 21 patients had osteosarcoma. For 22 of 99 patients (22%), discovery was due to subjective symptoms such as cough and sputum (n = 12), chest (or back) pain (n = 7) or hemosputum (n = 5). Ten of 19 patients (53%) with colon cancer experienced subjective symptoms which led to the discovery of metastases. In 76 of 99 patients (78%), metastatic lung lesions were not discovered through subjective symptoms. In 63 of those 76 patients, such lesions were initially found by plain chest roentgenography or CT. In 20 of 21 patients (95%) who had osteosarcoma, metastatic lung tumors were discovered by chest roentgenography or CT. In 14 of 76 patients, all of whom had metastatic lung carcinomas, the lesions were discovered through elevated levels of tumor markers. Therefore the importance of periodic chest roentgenography and tumor marker testing was demonstrated. Disease-free interval (DFI) was over six years in five of 32 patients (16%) with rectal cancer and 13 of 27 (48%) with breast cancer. DFI was less than five years for 15 of 19 patients (79%) with colon cancer, and less than two years for 16 of 21 (75%) with osteosarcoma. Thus, DFI differed according to the sites of the tumors. The five-year survival rates of 97 patients were examined. Patients were divided according to the sites of their primary tumors, and then subdivided according to the type of surgery they received. Patients were thus divided into five categories: I) those who underwent incomplete resection of metastatic lung lesions, II) those who underwent complete resection of both pulmonary lesions and involved mediastinal lymph nodes, III) those who had undergone previous treatment for tumors in organs other than the lung, IV) those who underwent complete resection of multiple lung lesions, and V) those who underwent complete resection of solitary lung lesions. For all primary sites, none of the patients in group I) survived for more than two years. Therefore complete resection seems very important for the treatment of metastatic lung tumors. With regard to the other groups, several facts were noted. For rectal cancer, the five-year survival rate of groups V) and III) was 55.6% in either case. Therefore complete resection of rectal cancer metastatic to the lung may improve the five-year survival rate even for patients who have previously been treated for cancers in organs other than the lung. For colon cancer, the five-year survival rate of group V) was 51.4%. Complete resection of only a solitary lung lesion may improve the five-year survival rate for colon cancer. For breast cancer, the five-year survival rate of group V) was 37.5% and that of group II) was 60.0%. This may indicate that for patients who have both pulmonary lesions and mediastinal lymph node involvement, complete resection of both is important. For osteosarcoma the five-year survival rate of group IV) was 26.0%. Thus, osteosarcoma patients have a chance of survival if they undergo complete resection of lung metastases.

To analyze the possible adverse effects of low dose methotrexate (MTX) therapy, 276 patients with rheumatoid arthritis (RA) were examined retrospectively. One hundred and seven patients (39%) experienced 113 adverse events : 57 showed liver dysfunction, 24 gastrointestinal complaints, 13 cutaneous symptoms, 6 respiratory symptoms, and 6 malignancies. Interestingly, 3 patients developed a dry cough without infiltration nor interstitial shadow on chest X-ray. The cough was rapidly resolved by discontinuation of MTX, but it recurred in 1 patient when MTX was re-administered. This finding might suggest a close association between MTX administration and the occurrence of dry cough. Of the 6 patients with malignancies diagnosed during MTX therapy, 2 showed malignant lymphoma, 2 lung cancer, 1 breast cancer and 1 colon cancer. MTX might have an oncogenic potential in RA because the coincidence rate, especially with respect to lymphoma, was significantly higher than estimated in a normal population.

A 57-year-old woman who had been operated on for colon cancer and given chemotherapy, presented in September 1995 with worsening cough and abnormalities on her chest X-ray film. Acid-fast bacilli were isolated from the sputum. The organism was classified as M. gordonae by biochemical tests and DNA/DNA hybridization. The patient was treated with rifampicin and clarithromycin. Subsequently, sputum cultures became negative and the chest x-ray film showed a decrease infiltration. The findings in the present case suggest that M. gordonae may cause pulmonary infection and should be considered as an opportunistic pathogen.

A 77-year-old man was in good health until he complained of fatigue 3 weeks before presentation. Two weeks before admission, he developed gradually worsening shortness of breath. One week before admission, he developed a cough that initially was nonproductive but later was associated with hemoptysis.His past medical history was remarkable for a history of colon cancer (Dukes' stage III), for which he underwent a hemicolectomy and treatment with adjuvant chemotherapy in 1993. He had a myocardial infarction in 1986 and underwent coronary artery bypass surgery in 1999. He also had a history of hypertension, type 2 diabetes, and gout. He smoked in the past but had stopped more than 30 years ago.He was initially evaluated by his primary care physician, who noted that he complained of diaphoresis but denied fevers, chills, or contact with others who were ill. His physical examination was remarkable for bilateral crackles that were more pronounced on the right. A chest radiograph demonstrated bilateral pulmonary infiltrates (Figure 1). He was treated with amoxicillin. The next day, however, his physician noted that his dyspnea had worsened and that his oxygen saturation on room air was poor. He was therefore admitted for further evaluation. The amoxicillin was discontinued, and he was treated with levofloxacin, followed by ceftriaxone and azithromycin as his pulmonary status continued to deteriorate. He received intravenous diuretic agents, which failed to improve his respiratory status. During the initial phase of hospitalization, he was anemic, with a hematocrit of 21.3%. His serum creatinine level, which had been 1.0 mg/dL in 1999, was now 2.5 mg/dL. Urinalysis was remarkable for the presence of numerous red blood cells. His oxygen requirement increased, and he eventually required a 100% nonrebreather mask. A computed tomographic scan of the chest demonstrated prominent alveolar opacities throughout the right upper, middle, and lower lobes, with similar opacities in the left upper and left lower lobes (Figure 2). An echocardiogram showed an ejection fraction of 50%, as well as mild mitral regurgitation. Serologies were remarkable for an antinuclear antibody titer of 1:320 and a P-antineutrophil cytoplasmic antibody (P-ANCA) titer of greater than 1:320. C-ANCA was negative. Anti-glomerular basement membrane and anti-human immunodeficiency virus antibodies were undetectable.

Three cases of metastatic lung tumor from colorectal cancer with an ineffectual systemic chemotherapy were examined based on the therapeutic effectiveness and safety of bronchial infusion (BAI) as a symptomatic therapy. Two out of three cases were rectal cancer and the third case being ascending colon cancer. After the operations, each of the three cases showed a multiple lung metastases recurrence at the primary and metastatic lesions of the lung. The lung metastases became large in size and thoracic symptoms (severe cough, chest pain) appeared in spite of the systemic chemotherapy of CPT-11, 5-FU and CDDP. A low dosage of BAI was administered by using CPT-11 (40 mg/m2) + CDDP (40 mg/m2) as one shot, and was repeated (three and six times respectively) for the two cases. When the low dosage of BAI was administered, there were light side effects and no complications were observed. The average hospital stay was 7.8 days. All three patients were stable and showed improvement in the condition of the disease. The prognoses from the first BAI were 3, 6, and 9 months in all three cases, respectively. BAI using low dosage of anti-cancer agents was effective, as means of improving the chest condition and quality of life in patients with metastatic lung tumor from colorectal cancer, with an ineffectual systemic chemotherapy.

Mr A is a 68-year-old man with a history of melena who was found to have a mass in his colon that was suspicious for possible malignancy. His 75-pack-year smoking history has resulted in a chronic daily cough and the diagnosis of chronic obstructive pulmonary disease. On physical examination, he has wheezes, decreased breath sounds, and a prolonged expiratory phase; his forced expiratory volume in the first second (FEV1) is 1.34 L (47% predicted). Mr A needs surgery for potentially curative treatment for presumed colon cancer, but he is understandably worried about the effect of his lung disease on his surgical risk. In particular, he is worried that he may not be able to be weaned off the ventilator after surgery. This discussion reviews the important patient- and procedure-related risk factors for pulmonary complications after surgery, the role of preoperative testing, and the evidence supporting strategies to reduce the risk of pulmonary complications as they apply to Mr A.

Constrictive bronchiolitis (CB) is a rare disease with unclear etiology. We report a 37-year-old female with CB who developed progressive dyspnea and cough after completing a course of 5-fluorouracil (5-FU) for colon cancer. The patient had evidence of irreversible obstructive lung disease and lung biopsy showed typical findings of chronic inflammation, submucosal thickening and obliteration of bronchioles. To the best of our knowledge this is the first reported case of CB after treatment with 5-FU.

Information concerning the pulmonary toxicity of oxaliplatin with infusional 5-fluorouracil plus leucovorin (FOLFOX) is very limited. We herein report the case of a patient with FOLFOX-induced interstitial pneumonia. An 82-year-old man with unresectable colon cancer liver metastases was referred to our department for chemotherapy with the FOLFOX protocol. After the administration of ten cycles, he visited our outpatient clinic with a 2-week history of coughing and shortness of breath; he was afebrile. A chest radiograph showed reticular shadows with ground-glass opacities mainly involving the middle and lower zones of the right lung. Computed tomography depicted ground-glass opacities with superimposed reticulation in the right lung. A diagnosis of FOLFOX-induced interstitial pneumonia was made based on the clinical course and imaging findings. The symptoms disappeared within 3 days after the cessation of the FOLFOX regimen and the initiation of high-dose corticosteroid treatment. Two months after the initiation of the corticosteroid treatment, complete remission of the radiological abnormalities was confirmed; thereafter, interstitial pneumonia did not recur despite the reintroduction of 5-fluorouracil/leucovorin alone, suggesting that 5-fluorouracil/leucovorin alone was not responsible for the development of the interstitial pneumonia. Thus, oxaliplatin, alone or in combination with 5-fluorouracil/leucovorin, may have caused the interstitial pneumonia in this patient. Once interstitial pneumonia has occurred, cessation of the regimen is mandatory, and high-dose corticosteroid treatment is commonly given to rescue patients from this potentially lethal complication.

A 64 -year-old female received oral S-1 chemotherapy followed by mFOLFOX6 chemotherapy for postoperative liver and lung metastasis of sigmoid colon cancer. The tumor progression was observed after twelve courses of mFOLFOX6 chemotherapy, and then FOLFIRI+bevacizumab chemotherapy was performed. After two courses of FOLFIRI+bevacizumab chemotherapy, leucopenia was observed. The chemotherapy was then discontinued and G-CSF was administered. Two days later she complained of high fever and dry cough, and was admitted to the hospital. A diffuse ground-glass appearance of bilateral lung was observed on chest X-ray and CT. Drug-induced interstitial pneumonitis was suspected, and Pneumocystis carini pneumonia was considered in the differential diagnosis. Oral administration of prednisolone and sulfamethoxazole/trimethoprim did not improve the symptoms, so steroid pulse therapy was performed. Steroid pulse therapy improved respiratory symptoms, but CT findings did not change remarkably. After nine weeks in the hospital, she was discharged with home oxygen therapy. Interstitial pneumonitis induced by FOLFIRI+bevacizumab chemotherapy is rare, but the number of cases may increase with increased use of this regimen. The possibility of interstitial pneumonitis should always be considered when the patient presents with a respiratory disorder while receiving systemic chemotherapy.

An 82-year-old woman with a past history of a colectomy for colon cancer was admitted to our hospital because of fever and cough. Her chest radiologic images on admission showed bilateral pulmonary infiltration, which suggested community-acquired pneumonia. However, the results of gram and acid-fast staining demonstrated branching acid-bacilli, which suggested pulmonary nocardiosis. We administered sulfamethoxazole-trimethoprim, and her condition and radiology findings promptly improved. Nocardia cyriacigeorgica was identified from her sputum. One of the nocardial isolates, formerly identified as Nocardia asteroides, has recently been reclassified as Nocardia cyriacigeorgica by the 16S rRNA gene amplification method. Pulmonary nocardiosis may be misidentified as "aspiration pneumonia", especially in elderly people. It is important for patients with community-acquired pneumonia to be evaluated with sputum gram staining for accurate diagnosis.
