Transdermal fentanyl (TDF) has been increasingly administered for the management of cancer pain. Occasionally, some patients fail to obtain poor analgesic effects with its dose escalation. We discuss a case of a 44-year-old male diagnosed with lung cancer with back pain caused by bone metastasis. He was administered a TDF of 75 microg/hr with good pain relief on admission. With time, the dose escalation to 300 microg/hr induced neuroexcitatory adverse effects without pain improvement. The conversion to 150 microg/hr TDF and sustained-release oral morphine 360 mg/day provided effective pain control. This clinical phenomenon demonstrated a possible association with the development of opioid tolerance. Although several experimental approaches regarding partial opioid substitution or combining different opioids for better pain control were suggested, the basic studies of opioid tolerance do not justify conclusions. In this case, partial opioid rotation and opioid combination were beneficial approaches to pain management.

Although small-cell lung cancer (SCLC) is a highly chemosensitive tumor, most patients relapse and have a poor prognosis. Relapsed patients become candidates for second-line or salvage chemotherapy. We report an effective case of weekly chemotherapy with carboplatin and paclitaxel in the treatment of a recurrent SCLC patient. A 58-year-old man diagnosed as SCLC received four courses of concurrent chemoradiotherapy with etoposide and cisplatin, and achieved a complete response. Solitary pulmonary metastasis was detected 9 months after chemoradiotherapy. He received second-line chemotherapy with irinotecan and cisplatin, but the mass remained as stable disease. Thus, thoracotomy was performed for the resection of the mass, and histological examination revealed a recurrence of SCLC. Pleural dissemination and multiple pulmonary metastases were detected, and he received third-line chemotherapy with amrubicin. However, there was evidence of recurrence, and he was given fourth-line chemotherapy with topotecan. Marked growth of pleural dissemination caused severe back pain, hence fifth-line chemotherapy using paclitaxel (70 mg/m(2); days 1, 8, and 15) and carboplatin (AUC 2; days 1, 8, and 15) was initiated. After three courses of chemotherapy, a good response was confirmed. The toxicity of chemotherapy was mild, and his symptoms including back pain completely disappeared. The patient has been alive now for 42 months after the initial therapy. Our result suggests that weekly chemotherapy with carboplatin and paclitaxel could be a well-tolerated and effective regimen for salvage chemotherapy of recurrent SCLC.

A 73-year-old woman who had been followed in our department of gynecology because of ovarian cancer since 2002, was admitted with liver dysfunction and complaining of back pain and light precordial chest pain. The chest radiograph on admission revealed a tumor in her left upper lung field, and chest CT revealed a tumor adjacent to the chest wall and mediastinum. FDG-positron emission tomography (PET) showed abnormal uptake in the tumor and Th6/7, and the subaortic lymph nodes. On the basis of these findings, primary lung cancer with bone metastasis was suspected. She had a high grade fever on admission, and blood cultures were positive for group G streptococcus. The treatment with intravenous penicillin was started. Percutaneous biopsy of the tumor in her left chest showed an abscess wall in the chest wall, but no evidence of malignancy. Transbronchial lung biopsy and CT-guided biopsy also showed no malignant cells. Since the tumor decreased in size and back pain improved gradually by only antibiotic treatment, a diagnosis of sepsis of group G streptococcus, chest wall abscess, and vertebral osteomyelitis was made. She was treated with intravenous penicillin for 4 weeks and oral amoxicillin for another 4 weeks. After 60 days of antibiotic treatment, the tumor vanished.

We present our experience with skeletal involvement of Pneumocystis jiroveci (ex P. carinii) infection in an HIV-seropositive patient. The objective of this study was to alert clinicians to the possibility that extrapulmonary P. jiroveci could affect the skeletal system in HIV-infected patients with extremely rapid progression. P. jiroveci infection of skeletal system has been rarely described elsewhere. A 51-year-old man complained of fever for six weeks, cough, anorexia, fatigue, and chest pain. He was found to be HIV seropositive. Repetitive (six samples) sputum and bronchoalveolar lavage fluid microbiologic tests were negative. High-resolution chest computed tomography (CT) scan revealed a small pulmonary mass. Abdominal CT scan revealed lesions in liver, spleen, kidneys, adrenal glands, lumbar vertebrae, and sacrum. Brain and skull CT scan was normal. A fine-needle biopsy of the lung mass was unrevealing. Cytological examination of sputum specimens showed findings consistent with non-small-cell lung carcinoma. Nineteen weeks post-presentation, the patient reported low-back pain. Within 24 hours after the onset of low-back pain, he developed focal neurological deficits, and a magnetic resonance imaging (MRI) of the skull and spine showed osteolytic lesions of the temporal bones bilaterally, multiple vertebral lesions, and lesions of sacrum and iliac bones. Radiotherapy of the lumbar spine and pelvis was given. Sternal aspiration was performed. Cytological examination revealed P. jiroveci. In conclusion, we describe a rare case of disseminated P. jiroveci infection in an HIV-seropositive patient, with multiple skeletal lesions, especially in the skull and in vertebrae region, and concomitant non-small-cell lung cancer, with a very poor prognosis.

A 68-year-old man complaining of hoarseness and back pain, with no history of exposure to asbestos, was referred to our hospital in June 2002. He was admitted because his chest X-ray and CT scan showed atelectasis and a tumor-like region in the right lower lobe of the lung. Serum-CYFRA was 2.8 ng/ml, elevated slightly; however, no other tumor markers for lung cancer were elevated. A diagnosis of squamous cell lung cancer was made based on bronchial washing cytology. Persistent high fever and WBC count elevation did not respond to antibiotics, and reduced only after chemotherapy. Both serum G-CSF (217.0 pg/ml) and CYFRA in the pleural effusion (107.1 ng/ml) were elevated. The biopsy of the growing tumor in the right lateral abdominal wall revealed carcinoma with sarcomatous component or biphasic-type malignant pleural mesothelioma (MPM). In spite of chemotherapy and radiation therapy for the abdominal wall tumor, the tumor rapidly progressed and the patient died three months after admission. The findings at autopsy suggested the tumor was a sarcomatous MPM. However, immunohistochemical staining and tissue HABP staining revealed biphasic type MPM. Although CYFRA elevation in the serum and/or the pleural effusion in MPM patients has been previously reported, it has not been reported in any of the 5 MPM patients reported to have G-CSF elevation. Therefore, this is the first reported case of G-CSF-producing MPM with CYFRA elevation in both serum and the pleural effusion.

A 78-year-old man was admitted to our hospital because of chest and back pain. Fourteen months previously his chest X-ray showed a tumor shadow with cavitation in the left middle field. On admission cardiomegaly was found. Chest CT without contrast enhancement did not detect an intra-myocardial tumor. The electrocardiogram and serological examination suggested acute onset of myocardial infarction. However, emergency coronary angiography detected neither significant stenosis nor occlusion. Thereafter, chest CT with contrast medium demonstrated an intra-myocardial tumor. There wes no pericardial effusion. We clinically diagnosed a myocardial tumor metastatic from lung cancer. He received symptomatic treatment, but died on the 31st hospital day. Autopsy revealed that most of the myocardium had been replaced by lung cancer cells. They did not invading the pericardium directly. These findings supported the clinical diagnosis that myocardial tumor was hematogenous metastasis from lung cancer.

A 60-year-old female smoker presented with bloody sputum and back pain. A computed tomographic (CT) scan of the chest revealed a mass lesion in S(1+2) of the left lung and hilarmediastinal lymphadenopathy. TBLB revealed small cell carcinoma. At first, we thought that the patient's clinical staging was c-T4N2M0 IIIB disease. However, it was pointed out she had had hilar-mediastinal lymphadenopathy 7 years previously. Though FDG-PET revealed an increased uptake in the hilar-mediastinal lymph node, she was determined to have surgery. The resected specimen revealed the swollen lymph nodes to be sarcoidosis, accompanying a large cell neuroendocrine carcinoma (LCNEL). She was treated with a combination chemotherapy consisting of cisplatin and VP-16 and radiotherapy concurrently. Chest CT revealed a partial response of the primary site after 3 courses of chemoradiotherapy. Information on concomitant malignancies accompanying sarcoidosis is limited. Although the main types of concomitant malignancy are lung cancer, and lymphoma, there has been no description of LCNEC as a concomitant malignancy. In sarcoidosis patients, clinicians should be alert to the possibility of concomitant malignancy.

A 56-year-old man visited another hospital complaining of hemoptysis. A chest radiograph showed expansion of the left upper mediastinum which seemed to be a mass-like lesion. He was referred to our hospital for further investigations. Before further examination, however, he presented to the emergency room with sudden onset of severe back pain. Rupture of a thoracic aortic aneurysm was suspected because of the clinical symptoms and the findings of emergency enhanced CT scanning. Emergency surgery was performed at the other hospital, and frozen section results indicated that the lesion was a non-small cell lung cancer. The pathology report of the surgical specimens revealed poorly differentiated adenocarcinoma of the lung with infiltration of the aortic wall. Postoperative chemotherapy was added, and the patient is doing well 10 months after operation. Some cases of tumor mimicking aortic aneurysm have been reported. We reported this case of lung cancer mimicking the rupture of a thoracic aortic aneurysm.

Neoplastic meningitis is a diffuse dissemination of tumour cells in the cerebrospinal fluid (CSF), leptomeninges, or both. It occurs in approximately 5-10% of malignant diseases, most often in breast cancer, lung cancer, melanoma, and B-cell lymphoma. Symptoms of neoplastic meningitis include head or back pain, cranial nerve palsies, diffuse radicular symptoms, and psychiatric disturbances. Magnetic resonance imaging shows nodular contrast enhancement lining the CSF spaces. Positive CSF cytology requires optimal sampling and processing, and the treatment of neoplastic meningitis must be individualized. The CSF dissemination can be treated with intrathecal chemotherapy with methotrexate or Ara-C. Radiotherapy should be applied only to symptomatic solid spinal manifestations or fast progressing cranial nerve palsies. Systemic chemotherapy is needed to control solid manifestations or, in the case of substances entering the CSF, to support intrathecal chemotherapy.

Lung cancer is rare disease in patients under 25 years of age. It typically occurs in older patients with a history of tobacco use. This case concerns a 20-year-old man with no history of tobacco use who complained of several months of cough and lower back pain and an 11.3-kg weight loss. He was treated for pneumonia after a chest radiograph showed total opacification of the right lung. Computed tomography imaging subsequently revealed a superior right hilar mass and mediastinal lymphadenopathy. Further imaging studies showed diffuse metastatic disease. Mediastinal biopsy showed poorly differentiated epithelioid tumour with desmoplastic stromal reaction, neutrophil infiltration, and squamous differentiation. Tissue immunostaining confirmed a non-small-cell lung cancer. Unfortunately, despite aggressive therapy, the patient's disease progressed, and he died within 9 months. In this paper, we hope to illustrate the unique challenges in diagnosing and treating young patients with metastatic lung cancer.
