肺癌部分性或完全性阻塞支气管时,在X线平片上常引起远侧肺的密度增高阴影。临床上它更是中央型肺癌的最初的X线表现之一,值得重视。自1949年Mc Dooald首次提出阻塞性肺炎名称以来,一直认为它是受侵肺的支气管内分泌物潴留后细菌继发感染所致。本文收集经手术、内镜、或分层、痰检证实的中央型肺癌180例,就胸部平片上呈现的X线表现进行分析发现:被阻塞支气管远端肺除有实变阴影外,尚有间质纤维增生,间质  相似文献

BACKGROUND: Breast cancer has been the subject of many recent studies because it is a significant cause of death in women. This study was performed to clarify whether solitary skeletal metastasis has clinical significance compared with multiple skeletal metastasis. PATIENTS AND METHODS: Seven hundred and three patients who developed metastatic bone lesions up to September 2002 after beginning treatment for breast cancer from 1988 to 1998 were included. The lesions were classified first as solitary or multiple based on bone scan results and then according to anatomical distribution. Next, solitary-to-multiple conversion was investigated in patients with solitary skeletal metastasis. Then factors related to solitary or multiple skeletal metastasis were analyzed. The prognosis of skeletal metastasis was compared between patients with solitary or multiple metastatic bone lesions. A Cox proportional hazards model was used to test whether solitary skeletal metastasis compared with multiple skeletal metastasis was an independent factor of survival. RESULTS: Two hundred and eighty-nine patients (41%) had solitary skeletal metastasis and 414 patients (59%) showed multiple skeletal metastasis. The sternum was a frequent site for solitary skeletal metastasis (98 of 289, 34%), while other skeletal sites were more frequent in patients with multiple metastatic bone lesions (P <0.001). Solitary sternal metastatic lesions remained solitary longer than solitary metastatic bone lesions to places other than the sternum (P <0.001), but did not lengthen patient survival times (P = 0.871). The factors related to solitary skeletal metastasis are TNM stage (tumor-node-metastasis) and histology. The patients with earlier stage and favorable histology tend to have solitary skeletal metastasis. The patients with solitary skeletal metastasis lived longer than those with multiple metastatic bone lesions (P <0.001). Multivariate analysis revealed that a solitary metastatic bone lesion (P = 0.002) is an independent favorable prognostic factor in patients with skeletal metastasis. CONCLUSIONS: Solitary skeletal metastasis has a different anatomical distribution and is an independent prognostic factor in patients with skeletal metastasis.  相似文献

The purpose of this preliminary study is to evaluate the characteristics of solitary pulmonary lesions in patients using extrapulmonary neoplasmas with 18F-fluoro-2-deoxyglucose positron emission tomography (FDG-PET). Thirty-two patients with extrapulmonary neoplasmas who had solitary pulmonary lesions and were suspected for pulmonary metastasis underwent an oncological survey with FDG-PET. Standard uptake value (SUV) and the ratio of lesion-to-background (L/B ratio) were used as parameters to differentiate and characterize the solitary pulmonary lesions. Using SUV > 2.5 or L/B ratio > 3 as the cutoff to diagnose malignancy, FDG-PET correctly identified 29 true-positive cases. However, FDG-PET failed to interpret two false-positive and one false-negative cases. The accuracy of FDG-PET was 91%. We concluded that FDG-PET is an accurate modality to differentiate solitary pulmonary lesions in patients with extrapulmonary neoplasmas.  相似文献

PURPOSE: To evaluate the efficacy and toxicity of hypofractionated stereotactic radiotherapy (HSRT) using noninvasive fixation of the skull on solitary or oligo brain metastatic patients as an alternative to stereotactic radiosurgery (SRS) using invasive fixation. PATIENTS AND METHODS: The subjects were 87 patients who had 4 or fewer brain metastases (50 solitary, 37 oligometastases). Treatment was conducted on 159 metastases by using a linac-based stereotactic system. The median isocentric dose was 35 Gy in 4 fractions. Whole-brain irradiation was not applied as an initial treatment. For the salvage treatment of metachronous brain metastases, repeat HSRT or whole-brain irradiation was applied. RESULTS: The actuarial 1-year local tumor control rate was 81%. Treatment-related complications were observed in 4 patients in the early period (<3 months) and in 2 patients in the late period. The median survival period was 8.7 months. Metachronous brain metastases occurred in 30 patients, and none of the 18 patients who were eligible for salvage HSRT refused to receive it again. CONCLUSIONS: Hypofractionated stereotactic radiotherapy achieved tumor control and survival equivalent to those of SRS reported in the literature. The results suggested that HSRT could be an alternative for solitary or oligo brain metastatic patients with less toxicity and less invasiveness compared to SRS.  相似文献

This study was conducted to determine prognostic factors for tumor response and patient survival after stereotactic radiosurgery (SRS) for brain metastasis. Eighty-four patients with brain metastasis underwent SRS at a single institution. After fixation of the head with a stereotactic frame, computed tomography treatment planning was performed. The metastatic lesion was treated with multiple arcs to a median dose of 19 Gy. Forty-seven patients (56%) had a solitary brain lesion. Fifty-nine patients (70%) had evidence of extracranial disease at the time of SRS. The median survival duration from SRS was 7 months. Sixty-three percent of the patients had an objective radiographic response to SRS, which in turn was associated with superior central nervous system control. Age, collimator size, number of arcs, tumor location, and histology did not influence objective response rates. Patients who had a solitary lesion or who received treatment within 2 weeks after diagnosis were more likely to have an objective response than were those who did not (P < 0.05). Progressive brain disease accounted for 37% of the deaths. Nineteen patients (23%) had an in-field relapse. Four severe complications were attributed to SRS. This study confirms the role of SRS as an acceptable treatment option for patients with solitary or limited brain metastases. Int. J. Cancer (Radiat. Oncol. Invest.) 90, 157-162 (2000).  相似文献

Objective: This study aimed to compare the clinico-pathologic features, recurrence rate and disease-free survival between colorectal cancers (CRCs) with synchronous advanced colorectal neoplasia (SCN) and solitary CRCs to determine the prognostic significance of SCN. Methods: A retrospective review of prospectively collected data of patients with CRCs was conducted in Phramongkutklao Hospital from January 2009 to December 2014. Patients were categorized in 3 groups: 1) solitary CRCs, 2) CRCs with advanced colorectal adenomas (ACAs) but having no another cancer and 3) synchronous colorectal cancers (S-CRCs) with or without ACAs. Patients undergoing curative resection and complete standard adjuvant treatment were recruited to evaluate the prognostic significance of SCN.  Clinicopathologic features, recurrence rate and disease-free survival were analyzed to compare among different groups.  Result: Among 328 recruited patients, 282 were classified as solitary CRCs (86%), 23 as CRCs with ACAs (7%) and 23 as S-CRCs (7%). Patients with CRCs with SCN (groups 2 and 3) were significantly older than patients with solitary CRCs (p <0.01), and SCN was found more commonly among males (15.2%) than females (12.3%) (p=0.045). In all, 288 patients achieved a curative resection and accomplished complete standard postoperative adjuvant treatment. Of these, the accumulative number of patients experiencing tumor recurrence was 11.8, 21.2, 24.6, 26.4 and 26.7% at the 1-, 3-, 5-, 7- and 10-year surveillance period, respectively. The disease-free survival of the groups with SCN was marginally higher than that of solitary CRCs groups (p=0.72) (solitary CRCs, 120.7±4.4 months; CRCs/ACAs, 127.4±13.9 months and S-CRCs: 126.2±13.6 months). Conclusion: CRCs with SCN were found at a more advanced age than those with solitary CRCs. SCN was found more often among males than females. After achieving curative resection and complete adjuvant treatment, the recurrence rate and disease-free survival of CRCs with SCN did not significantly differ from those of solitary CRCs.  相似文献

Solitary fibrous tumors are uncommon spindle cell neoplasms originally thought to be restricted to the pleura. We describe a 62-year-old woman who presented with stridor and an anterior mediastinal mass. At thoracotomy, a 10.5 x 6.5 x 5.5 cm, circumscribed, firm mediastinal mass demonstrated no direct cardiac or pulmonary involvement. The tumor consisted of spindle cells organized in a patternless pattern with collagenous stroma and hemangiopericytoma-like vessels. Spindle cells were immunoreactive for CD34, CD99, desmin, vimentin and bcl-2 protein and a diagnosis of mediastinal solitary fibrous tumor was confirmed. The differential diagnosis of mediastinal solitary fibrous tumors is extensive and includes spindle cell thymoma, sarcomatoid carcinoma, malignant mesothelioma, inflammatory myofibroblastic tumor, peripheral nerve sheath tumors and various sarcomas. Despite their rarity in the mediastinum, solitary fibrous tumors can be recognized by their classic patternless morphology and immunophenotypic pattern. Their accurate classification is important, as solitary fibrous tumors are intermediate (rarely metastasizing) neoplasms that require complete surgical excision and long-term clinical follow-up for optimum therapy.  相似文献

"Suddenly a solitary horseman appeared on the horizon, then another, then another...in a few moments a whole crowd of horsemen swooped down upon him."-Leacock The illusion of solitary metastases is counterintuitive but has generated a sizable literature on the subject. The reality is that there are more metastatic deaths each year than the total number of true long-term survivors of solitary metastases combining all organ sites in the literature of the past century up to the present time. The largest number of solitary metastases survivors had metastases primarily in the lung and/or liver. With innovations in molecular imaging and advances in molecular oncology, the stage is set to detect truly solitary metastases early. Then, aggressive treatment by surgical excision, stereotactic body radiosurgery, targeted chemotherapy, or immunotherapy could eradicate the lesion. A comprehensive review of solitary metastases in a large variety of anatomic sites is presented. A broader staging system is recommended to encompass a solitary metastasis (M1) and oligometastases (M2) as distinct from multiple metastases (M3).  相似文献

BACKGROUND: Solitary brain metastases occur in about 50% of patients with brain metastases from nonsmall cell lung cancer (NSCLC). The standard of care is surgical resection of solitary brain metastases, or stereotactic radiosurgery (SRS) plus whole brain radiation therapy (WBRT). However, the optimal treatment for the primary site of newly diagnosed NSCLC with a solitary brain metastasis is not well defined. The goal was to distinguish which patients might benefit from aggressive treatment of their lung primary in patients whose solitary brain metastasis was treated with surgery or SRS. METHODS: The cases of 84 newly diagnosed NSCLC patients presenting with a solitary brain metastasis and treated from December 1993 through June 2004 were retrospectively reviewed at The University of Texas M. D. Anderson Cancer Center. All patients had undergone either craniotomy (n = 53) or SRS (n = 31) for management of the solitary brain metastasis. Forty-four patients received treatment of their primary lung cancer using thoracic radiation therapy (median dose 45 Gy; n = 8), chemotherapy (n = 23), or both (n = 13). RESULTS: The median Karnofsky performance status score was 80 (range, 60-100). Excluding the presence of the brain metastasis, 12 patients had AJCC Stage I primary cancer, 27 had Stage II disease, and 45 had Stage III disease. The median follow-up was 9.7 months (range, 1-86 months). The 1-, 2-, 3-, and 5-year overall survival rates from time of lung cancer diagnosis were 49.8%, 16.3%, 12.7%, and 7.6%, respectively. The median survival times for patients by thoracic stage (I, II, and III) were 25.6, 9.5, and 9.9 months, respectively (P = .006). CONCLUSIONS: By applying American Joint Committee on Cancer staging to only the primary site, the thoracic Stage I patients in our study with solitary brain metastases had a more favorable outcome than would be expected and was comparable to Stage I NSCLC without brain metastases. Aggressive treatment to the lung may be justified for newly diagnosed thoracic Stage I NSCLC patients with a solitary brain metastasis, but not for locally advanced NSCLC patients with a solitary brain metastasis.  相似文献
