Protocol applies to malignant pleural mesothelioma.
Procedures
Cytology
This protocol is intended to assist pathologists in
providing clinically useful and relevant information as a result of the
examination of surgical specimens. Use of this protocol is intended to be
entirely voluntary. If equally valid protocols or similar documents are
applicable, the pathologist is, of course, free to follow those authorities.
Indeed, the ultimate judgment regarding the propriety of any specific procedure
must be made by the physician in light of the individual circumstances
presented by a specific patient or specimen.
It should be understood that adherence to this
protocol will not guarantee a successful result. Nevertheless, pathologists are
urged to familiarize themselves with the document. Where a physician chooses to
deviate from the protocol based on the circumstances of a particular patient or
specimen, the physician is advised to make a contemporaneous written notation
of the reason for the procedure followed.
The College recognizes that this document may be
used by hospitals, attorneys, managed care organizations, insurance carriers,
and other payers. However, the document was developed solely as a tool to
assist pathologists in the diagnostic process by providing information that
reflects the state of relevant medical knowledge at the time the protocol was
first published. It was not developed for credentialing, litigation, or
reimbursement purposes. The College cautions that any uses of the protocol for
these purposes involve considerations that are beyond the scope of this document.

EXPLANATORY NOTES
A. Special
Studies back Top Main Page
Immunohistochemistry and electron microscopy have
become important adjuncts to routine microscopic evaluation in the diagnosis
and classification of malignant mesothelioma.(1-7)
B. Histologic
Type back Top Main Page
For consistency in reporting, the histologic
classification published by the World Health Organization (WHO) is recommended.(8)
However, other classifications may be used. The more detailed histologic
classification of malignant mesothelioma by Hammar recognizes histologic
variations which might be confused with other neoplasms and points out light
microscopic similarities to benign pleural cells including the surface
mesothelial cell and the multipotential subserosal spindle cell.(9)
The localized fibrous tumor of the pleura
(previously referred to as localized fibrous mesothelioma) is not included in
this protocol since it is generally regarded as a benign tumor arising from the
subserosal fibrous tissue rather than to the mesothelium.(10)

C. Histologic
Grade back Top Main Page
There is no specific recommended histologic grading
system for malignant mesothelioma of the pleura.
The protocol recommends the American Joint
Committee (AJCC) and International Union Against Cancer (UICC) TNM Staging
System shown below.(11,12) However, the protocol does not preclude the use of
other staging systems such as the staging system of the International
Mesothelioma Interest Group Staging System which is also shown below.(13)
TNM
and Stage Groupings
By AJCC/UICC convention, the designation T
refers to a primary tumor that has not been previously treated. The symbol p
refers to the pathologic classification of the TNM, as opposed to the clinical
classification and is based on gross and microscopic examination. pT entails a resection of the primary tumor
or biopsy adequate to evaluate the highest pT category; pN entails removal of
nodes adequate to validate lymph node metastasis; and pM implies microscopic
examination of distant lesions.
Clinical classification (cTNM) is usually carried out by the referring
physician before treatment during initial evaluation of the patient or when
pathologic classification is not possible.
Tumor
Remaining in the Patient
Tumor remaining in a patient after therapy with
curative intent (e.g., surgical resection for cure) is categorized by a system
known as R classification, shown below.
RX Presence
of residual tumor cannot be assessed
R0 No
residual tumor
R1 Microscopic
residual tumor
R2 Macroscopic
residual tumor.
For the surgeon, the R classification may be
useful to indicate the known or assumed status of the completeness of a
surgical excision. For the pathologist,
the R classification is relevant to the status of the margins of a surgical
resection specimen. That is, tumor
involving the resection margin on pathologic examination may be assumed to
correspond to residual tumor in the patient and may be classified as
macroscopic or microscopic according to the findings at the specimen margin(s).
Tumor
Remaining in a Specimen
In contrast, tumor remaining in a resection
specimen from a patient who has undergone previous (neoadjuvant) treatment of
any type (radiation therapy alone, chemotherapy therapy alone, or any combined
modality treatment) is codified by the TNM using a prescript y (e.g.,
ypT1). Thus, yTNM indicates the
post-treatment status of the tumor. For
many neoadjuvant therapies, the classification of residual disease may be a
strong predictor of postoperative outcome.
In addition, the ypTNM classification provides a standardized framework
for the collection of data needed to accurately evaluate new neoadjuvant
therapies.
Locally
Recurrent Tumor
In contrast to residual tumor, classification
of a tumor as recurrent requires a documented disease-free interval after
definitive therapy. Recurrent tumor may
also be classified according to the TNM categories, but the prefix r (e.g.,
rpT1) is used to indicate the recurrent status of the tumor.
