Follow-up and Surveillance – Curatively-Treated Lung Cancer

Follow-up and Surveillance Recommendations for Patients Treated Curatively for Lung Cancer.


Background:

Despite advances in the care of patients with NSCLC, the overall 5-year survival for patients treated with curative intent remains poor. The rationale for surveillance following the treatment of lung cancer is the detection of recurrent disease or a new primary lung cancer, no randomized data exist to support specific recommendations for surveillance modality and interval. Most recommendations are based on expert consensus and cohort studies, and the effect of surveillance on survival continues to be debated. Data extrapolated from screening trials does demonstrate a survival benefit to the detection of early stage cancers and most guideline-setting groups recommend a surveillance strategy involving regular clinical examinations and imaging. 1-8, 10-16

Recommendations

  • Surveillance for early recurrence or new primaries in patients treated with curative intent for NSCLC:
    • Low dose CT chest +/- contrast q6mo in years 1 and 2 1-5,9,17,18
    • Low dose CT chest +/- contrast q12mo years thereafter1-5,9,17,18
  • CT dose (i.e. Low dose vs Minimal dose) and the use of contrast is controversial. There are no data to suggest one dose over another. Extrapolation of data from the National Lung Cancer Screening Trial would suggest Low dose CT provides good sensitivity for the detection of early stage cancers.4,5,6
  • Surveillance for early recurrence or new primaries in patients treated with curative intent for SCLC:
  • Surveillance recommendations for surveillance post curative intent treatment of SCLC are based on expert consensus and parallel those for NSCLC.
  • Contrast enhanced CT chest may provide superior assessment of mediastinal nodal involvement18

Recommendations for Invasive Mediastinal Staging for Potentially Resectable NSCLC – Choice of Invasive Modality

Indications for Invasive Mediastinal Staging for Potentially Resectable NSCLC

A. When is invasive mediastinal staging indicated?

Background:

As a general rule, invasive staging is typically held to be indicated when the risk of mediastinal lymph node involvement is 10% or greater. There is significant agreement in the existing published guidelines based on moderate to high quality evidence for the following recommendations.

Recommendation

Invasive mediastinal staging is indicated in patients with:

  • Primary tumour >/= 3cm 1-15
  • Central tumour* 1-3, 7, 13, 16-19
  • CT evidence of enlarged N1/N2/N3 nodes 1, 2, 5, 10, 16, 17, 20-23
  • PET evidence of avid N1/N2/N3 nodes 1, 2, 5, 16, 17, 22-25

Note:   Emerging evidence in smaller series has also identified other factors that are associated with an increased risk of mediastinal lymph node involvement. It is not well established if the risk is high enough to justify invasive staging on the basis of these risk factors alone in the absence of the above indications. These additional factors may supplement decision making on a case by case basis:

  • Adenocarcinoma histology 3, 8, 13, 20, 27-29
  • High SUVmax of the primary tumour** 5, 12, 13, 30-34
  • Elevated serum CEA***4, 10, 11, 15, 35

*“Central” is inconsistently defined in the literature26. At the minimum, tumours within the central 1/3 of the chest should undergo invasive staging.
**The threshold value of SUVmax associated with increased risk varies between studies and is poorly defined.
***This test is not a routine part of the work-up of lung cancer in North America

Choice of Invasive Modality

B. Choice of invasive modality

Background

When invasive mediastinal staging is required. Various modalities maybe utilized including, but not limited to cervical mediastinoscopy (CM), endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS). This set of recommendations will compare these techniques and attempt to set some parameters regarding required nodal stations. In doing so, we are very cognizant of the variation in the technology and expertise available at the various Thoracic Surgery centres across the country.

Recommendations

  1. Both cervical mediastinoscopy (CM) and needle (FNA) techniques (EBUS with or without EUS) have excellent reported sensitivity, negative predictive value and accuracy.

Initial reports on the accuracy of EBUS and EUS in lung cancer staging yielded disappointing results with unacceptably high false negative rates. However, more contemporary reports have shown equivalence. Indeed, with wider access to mediastinal lymph node staging, needle techniques may prove to be superior to conventional surgical staging. Combined EBUS and EUS, for example, affords access at lymph nodes from station 2R, 2L, 3p, 4R, 4L, 5, 6, 7, 8R, 8L, 9R, 9L, 10R, 10L, 11R and 11L.

  1. We recommend that invasive mediastinal staging, whether with mediastinoscopy or needle techniques should include sampling of at least the right paratracheal lymph node station (station 4R), left paratracheal lymph node station (station 4L) and subcarinal lymph node (station 7), as well as any other suspicious lymph node station by CT or PET criteria

Conventional reports of adequate mediastinoscopy in invasive staging of the mediastinum stipulate that both lower paratracheal lymph node stations and the subcarinal lymph node station should be sampled. While there may not be a lot of evidence that support this convention, it does seem like a reasonable and valid recommendation. This same rule should apply to needle techniques for the same reasons. Therefore, regardless of procedure, an invasive mediastinal staging procedure should only be considered adequate if it samples lymphoid tissue from both lower paratracheal lymph nodes and subcarinal lymph node, and any lymph nodes that are considered suspicions by CT or PET. For example, in a patient with a right upper lobe tumor and a suspicious high paratracheal lymph node by PET, and adequate mediastinoscopy or EBUS would include lymphoid tissue sampled from at least stations 4R, 4L, 7 and 2R.

  1. If both procedures are readily available at an institution, then needle techniques (preferably under sedation in an endoscopy suite) should preferentially be selected to cervical mediastinoscopy

The most important factors in selecting which procedure to use is whether the selected procedure is performed adequately with good results, and whether the target lymph nodes are within reach of that procedure. For example, using mediastinoscopy alone in a patient with left lower lobe tumor and a suspicious lower paraesophageal lymph node (station 8L) would not be considered adequate even if lymph node tissue is adequately obtained from stations 4R, 4L and 7. However, in situations where both procedures can be used safely and adequately, the panel recommends a needle technique. This is because of the lower incidence of devastating complications and the lower cost associated with needle techniques. One should note, that the cost advantage of needle techniques is more pronounced when they are performed in an endoscopy suite.

  1. In an institution where needle techniques are available with high quality, there is no need to confirm negative results with a more invasive procedure.

Given the equivalent results obtained by both procedures in the right setting, the practice of routinely confirming negative EBUS or EUS resulted is not supported by the current literature and is not necessary. There are situations where a negative EBUS or EUS result may require confirmation with a more invasive technique, such as CM or thoracoscopy. This includes inadequate samples or highly suspicious lymph nodes by imaging criteria that are unexpectedly negative.
