This chapter of the Lung Cancer Guidelines addresses patients with particular forms of non-small small room lung cancer that require special considerations. This includes patients with Pancoast tumors, T4N01M0 tumors, satellite nodules in the same lobe, synchronous and metachronous multiple primary lung cancers (MPLC) and solitary metastases. For patients with a Pancoast tumor, a multimodality approach, involving chemoradiotherapy and surgical resection, appears optimal provided appropriate staging has been carried revealed Patients with central T4 tumors that do not have mediastinal node involvement are rare When carefully staged and prefered however, such patients appear to benefit from resection as part of the treatment as oppos to chemoradiotherapy alone. Patients with a satellite lesion in the same lobe as the primary tumor have a convenient prognosis and require no modification of the approach to evaluation and treatment from what would be dictated from the primary tumor alone. forward the other hand, it is difficult to know in what manner best to treat patients with a focus of the same representation of cancer in a different lobe. Although MPLC do fall out the survival results after resection for either a synchronous presentation or a metachronous presentation with an interval of < 4 years between tumors are variable and generally poor, suggesting that many of these patients may have had a pulmonary metastasis rather than a other primary lung cancer. A thorough and careful evaluation of these patients is warranted to put to proof to differentiate between patients with a metastasis and those with a other primary lung cancer, although criteria to distinguish them have not been defined. Finally, more [i]or[/i] less patients with a solitary focus of metastatic disease in the brain or adrenal gland appear to benefit substantially from resection.

In general, patients with an early stage non-small small cavity lung cancer (NSCLC) without mediastinal nodal involvement (stage I and II) are treated primarily with surgery whereas those with a locally advanced lung cancer with mediastinal nodal involvement (stage IIIA and IIIB) are treated with chemotherapy and radiation. However, there are several relatively unusual presentations of NSCLC in which the anatomic and biological issues appear to dictate a different approach. In addition, the appearance of an isolated second focus of cancer in a patient with lung cancer quick in emergenciess a situation where the biology of this phenomenon is ofttimes not clear, and therefore the approach to treatment is difficult.

This section addresses patients with particular forms of NSCLC that require special considerations. These include patients with Pancoast tumors, T4N01M0 tumors, satellite nodules in the same lobe, synchronous and metachronous multiple primary lung cancer (MPLC) and solitary metastases. The purpose of this project did not allow inclusion of special histologic originals of lung cancer, such as typical and atypical carcinoid tumors, mucoepidermoid tumors, or bronchioloalveolar carcinomas.

METHODS

A formal meta-analysis was not available for any of the particular forms of NSCLC that are the enslave of this chapter, and resources did not permit the American association of Chest Physicians (ACCP) to career such an analysis independently. Clinical guidelines from other organizations were available sole with regard to Pancoast tumors. These involve primarily consensus opinion statements and are discussed in the section onward Pancoast tumors. (1-5) However, a systematic review of literature in each of these areas is available, published in the year 2001 (6) The recommendations in this section rely heavily in succession the data from this review.

The data regarding the approach to these special situations was reviewed, summarized, and used to define management recommendations according to the writing committee. This document was then reviewed by dint of three independent reviewers, and further changes were made. The revised document and recommendations were further reviewed according to the entire ACCP Guidelines committee to assure that it met the requirements of a balanced, accurate, and generally acceptable representation of the issues with regard to these particular forms of NSCLC

PANCOAST TUMORS

Definition

Lung cancers that appear in the apex of the chest and invade apical chest wall constitutions are called superior sulcus tumors or Pancoast tumors. The classic description of like patients involves a syndrome of pain radiating down the arm as a manifestation of brachial plexus involvement. With improvements in radiographic techniques, earlier diagnosis, and a more detailed understanding of the anatomy, a tumor can be classified as a Pancoast tumor if it invades any of the forms at the apex of the chest, including the greatest in number superior ribs or periostium, the lower invigorate roots of the brachial plexus, the sympathetic chain near the apex of the chest, or the subclavian bottoms These tumors are now divided into anterior, middle, and posterior compartment tumors depending forward the location of the chest wall involvement in relation to the insertions of the anterior and middle scalene muscles forward the first rib. (7) A syndrome of pain radiating down the arm is no longer a prerequisite for an apical tumor to be designated a Pancoast tumor.
