Abstract

AIMS AND OBJECTIVES

To evaluate the pattern of chest radiographs findings in metastatic cancer patients at first presentation in a tertiary hospital in northern Nigeria with a view to contributing to existing literature and making recommendation for optimal patients care in Nigerian hospitals.

PATIENTS AND METHODS

From January 2002 to December 2007, 712 new patients were seen and 688 patients' chest radiographs excluding children (below 16 yr) were reviewed of which 118 were considered abnormal due to pathology arising from primary cancer. Those Chest radiographs showing pathology not related to cancer were excluded. Results were analysed using EPI-Info, version 3.4.1. 2007.

RESULTS

118 (17%) patients' chest radiographs (CXR) were having evidence of metastases from primary cancer. The sex ratio is M: F = 1: 1.7 with a mean age of 48.1 years (Range 16 - 82 yrs). Breast cancer was the commonest cause of metastatic spread to the lungs seen in 44 (37.3%) patients followed by colorectal 10 (8.5%), soft tissue sarcoma 9 (7.6%), and bone sarcoma 8 (6.8%). Cervical cancer which was the commonest type of malignancies seen at presentation accounted only for 8 (6.7%) cases. Both lungs were involved in 62 (52.5%) patients, followed by right lung alone in 42 (35.6%) cases and left lung alone in 14 (11.9%) cases. The mid zone was the commonest site of lung metastases 102 (86.4%) followed by lower zone 42 (35.6%). Pleural effusion seen in 26 (22%) patients affected both lungs equally. Multiple lung metastases were the predominant pattern of metastases seen in 94 (80%) cases. Majority 82 (69.5%) of lungs metastases were of sizes less than 2cm.

CONCLUSION

Multiple lung metastases were the commonest pattern of lung metastases. Both lungs and mid zone were mainly affected. Lung metastases were very common from breast, colorectal, bone sarcoma, prostate cancers but relatively rare from cervical, head and Neck cancers and lymphomas. Chest radiographs should be part of initial evaluation of all cancer patients.

摘要

目的与目标

评估尼日利亚北部一家三级医院初次就诊的转移性癌症患者的胸部X光片检查结果模式，以期为现有文献提供补充，并为尼日利亚医院的最佳患者护理提供建议。

患者与方法

2002年1月至2007年12月，共诊治712例新患者，对688例（不包括16岁以下儿童）患者的胸部X光片进行了复查，其中118例因原发性癌症引发的病变被视为异常。排除那些显示与癌症无关病变的胸部X光片。使用EPI-Info 3.4.1版本（2007年）对结果进行分析。

结果

118例（17%）患者的胸部X光片显示有原发性癌症转移的迹象。男女比例为1:1.7，平均年龄48.1岁（范围16 - 82岁）。乳腺癌是肺转移最常见的原因，44例（37.3%）患者出现这种情况，其次是结直肠癌10例（8.5%）、软组织肉瘤9例（7.6%）和骨肉瘤8例（6.8%）。初次就诊时最常见的恶性肿瘤类型宫颈癌仅占8例（6.7%）。62例（52.5%）患者双侧肺均受累，其次是仅右肺受累42例（35.6%），仅左肺受累14例（11.9%）。肺转移最常见的部位是中区102例（86.4%），其次是下区42例（35.6%）。26例（22%）患者出现胸腔积液，双侧肺受累情况相同。94例（80%）病例中，多发性肺转移是主要的转移模式。大多数82例（69.5%）肺转移灶大小小于2厘米。
