IASLC Multidisciplinary Recommendations
for Pathologic Assessment of Lung Cancer
Specimens Following Neoadjuvant Therapy1
Full abbreviations, accreditation, and disclosure information available at
PeerView.com/YRK40
Recommendation 1
The term “tumor bed” is the area where the original pretreatment tumor was considered to be located. It can be
challenging to determine whether necrosis and stromal inflammation and/or fibrosis are due to regression secondary to
neoadjuvant therapy, native tumor characteristics, or a combination. For this reason we favor the term tumor bed. It is
suggested to simply describe the major components of the tumor bed as (1) viable tumor, (2) necrosis, or (3) stroma
(which can include inflammation or fibrosis). See page 3 for an example.
Recommendation 2
It is essential that information be provided from the surgical team to the pathology laboratory on whether the patient
received neoadjuvant therapy in order for this specimen processing protocol to be followed. If there is more than one
tumor in the specimen, it is of critical importance to also provide this information. It is good clinical practice to correctly
label the specimen with the lobe(s) resected and to clarify any issues that may be needed for pathologic staging such
as the pericardium, diaphragm, or chest wall.
Recommendation 3
Lung cancer resection specimens following neoadjuvant therapy should be sampled to optimize comprehensive gross
and histologic assessment of the lung tumor bed for pathologic response. The tumor should be cut in its greatest
dimension to maximize the tumor bed cross section. In cases where identification and/or orientation of the tumor are
difficult, review of the preoperative CT scan can be helpful. Tumors 3 cm or less in size should be completely sampled.
For larger tumors greater than 3 cm, the tumor should be cut across in serial sections 0.5 cm thick, and after gross
inspection, the most representative cross section showing viable tumor should be sampled. At least one cross section
of the entire tumor (0.5 cm thick) with a gross photograph and histologic mapping should be made. Histologic sections
at the tumor periphery should include 1 cm of adjacent lung parenchyma. Pathologic response cannot be assessed in
small biopsies; a resection specimen is required.
Recommendation 4
To determine the border of the tumor bed, the edge of the tumor needs to be distinguished from the surrounding
non-neoplastic lung parenchyma. This can be facilitated by review of the gross specimen and the histologic slides
from the periphery of the tumor bed.
Recommendation 5
Determination of the pathologic response to therapy should be made after review of all HE slides of tumor by
estimating the percentages of (1) viable tumor, (2) necrosis, and (3) stroma, which includes both fibrosis and
inflammation, so each of these three components add up to 100%. Each component should be assessed in 10%
increments unless the amount is below 5% when an estimate of single percentages should be recorded. While this
is primarily done by review of histologic sections of the tumor bed, correlation with the gross findings, in some cases
facilitated by a gross photograph, may be important in markedly necrotic and/or cavitated tumors where it is not
possible to reflect this change in histologic sections.
Note: Although it may be useful to record the amount of each of these components on each individual histologic slide,
it needs to be kept in mind that the amount of tumor bed varies on each slide, so these percentages cannot be summed
and averaged as if they were in equal amounts. This is a semiquantitative process. There is no validated quantitative
method that is available that can be implemented in a timely fashion for clinical decisions.
A proposed synoptic template for reporting pathologic findings for resected lung cancers following neoadjuvant therapy
is summarized on page 2.

Recommendation 6
Definition of major pathologic response (MPR)
MPR is defined as the reduction of viable tumor to the amount beneath an established clinically significant cutoff based
on prior evidence according to the individual histologic type of lung cancer and a specific therapy.
The historical definition of MPR for all histologic types of lung cancer is ≤10% of viable tumor with no viable tumor
required for pathologic complete response (pCR). MPR is calculated as the estimated size of viable tumor divided by
the size of the tumor bed. For the moment, this is the cutoff being used in multiple active clinical trials. However, recent
data suggests the MPR in the conventional chemotherapy setting may differ according to histologic type: ie,
adenocarcinoma versus squamous cell carcinoma.
If after review of histologic sections, the percentage of viable tumor is near the cutoff for major pathologic response,
additional histologic sections should be submitted. The pathology report should record the total number of blocks of
tumor bed that were examined even if the blocks did not consist entirely of tumor bed but also included some
uninvolved lung.
For colloid adenocarcinomas, where tumor cells are only focal, the mucin pools should be included in the percentage
of viable tumor. However, if there are only areas of extracellular mucin without any apparent viable tumor cells within
the mucin, we suggest regarding this as stroma. Further study is needed to address this point.
Major pathologic response can also be classified for the lung primary in the setting where the lung primary shows
little or no viable tumor, but lymph nodes show viable metastatic carcinoma (ypT0, N1, 2 or 3). However, the prognostic
and therapeutic implications of this clinical setting are not known.
Recommendation 7
Definition of pathologic complete response (pCR)
pCR is defined as lack of any viable tumor cells on review of HE slides after complete evaluation of a resected lung
cancer specimen including all sampled regional lymph nodes. Such tumors would be staged as ypT0N0 according to
the 8th edition AJCC and UICC staging systems.
Note:
If no tumor is seen in the initial sections and tissue from the tumor bed remains, additional histologic sections should
be made. The number of additional sections should be whatever seems reasonable in the individual setting depending
on the size of the tumor bed and the capacity of the individual pathology laboratory. If the histologic changes in the initial
sections obtained do not show findings that fit for the effects of therapy, the possibility that the wrong area was sampled
should be considered. In such cases the gross specimen may need to be re-evaluated using radiologic pathologic
correlation and if additional lesions are identified, these should be sampled. The pathology report should record the
total number of blocks of tumor bed that were examined even if the entire block did not consist of tumor bed.
The identification of incidental lesions of squamous cell carcinoma in situ, atypical adenomatous hyperplasia,
adenocarcinoma in situ, or minimally invasive adenocarcinoma in the surrounding lung parenchyma that are clearly
separate from the main tumor for which neoadjuvant therapy was administered does not disqualify a case for
classification as MPR or CPR. This proposal is based on clinical judgement, as currently no clinical data exist to
make a specific recommendation.
In the setting of multiple tumors where a second invasive predominant lung carcinoma, is present that was regarded
preoperatively to be an intrapulmonary metastasis but, it is determined to be a second synchronous primary after
clinical, radiologic, pathologic, and/or molecular assessment, it is questionable whether the terms MPR or CPR should
be used if the main tumor otherwise meets the above criteria. No data exists currently to address this question.

Recommendation 8
In the absence of more systemic data regarding evaluation of tumors following immunotherapy and molecular targeted
therapy, the same approach to pathologic assessment of resected lung cancers in the neoadjuvant setting in evaluating
the percentage of viable tumor, necrosis, and stroma should be used regardless of the type of neoadjuvant therapy
administered whether it was radiation, chemotherapy, targeted therapy, immunotherapy, chemoradiation,
chemoimmunotherapy, or chemotherapy-targeted therapy. There also may be different features that can be addressed
depending on the type of therapy such as immune cell infiltrates in patients who received immunotherapy.
Recommendation 9
In most cases, the lymph nodes are small enough to completely sample, but if there is a very large metastasis or tumor
bed (2 cm), the lymph node can be bisected and the central slice through the tumor can be submitted in designated
cassettes. This should also be done during grossing of intraoperative frozen sections of lymph nodes. Depending on
individual laboratory resources, more extensive or even complete sampling can also be done. Then the same approach
can be used for histologic evaluation that is used for the resected lung cancer reporting percent viable tumor, necrosis,
and stroma. Complete pathologic response in a lymph node can be recognized if there is a well-defined scar and/or area
of tumor necrosis in the absence of identifiable viable tumor cells.
Recommendation 10
The following recommendations are made for T factor staging of neoadjuvant lung cancer resection specimens.
Tumor size:
If the viable tumor forms a discrete mass where the size can be measured with a ruler either grossly or microscopically
(where it can be measured on a single HE slide), this is the preferred approach (see figure). However, if the viable
tumor cannot be measured with a ruler either due to grossly indistinct borders, multiple foci interspersed among
necrosis and/or stroma, or if it is present on multiple slides, the viable invasive tumor size should be estimated using
the following formula.
Viable invasive tumor size (cm) = tumor bed size X percentage viable invasive tumor
Estimating invasive size by adjusting for lepidic component
In tumors that have a component of lepidic growth, tumor size estimation should use the principles introduced in the 8th
Edition TNM classification that record both total size and invasive size, but only use invasive size for T-factor
determination. Thus, in the neoadjuvant setting, viable tumor size estimation for such cases may need two adjustments:
one for invasive size excluding the lepidic component and a second for the percent viable tumor as outlined above.
However, the clinical implications of this adjustment for the lepidic component are not known in the neoadjuvant setting.
T3: multiple tumors considered to represent intrapulmonary metastases
If there is more than one tumor within a lobe, the pathological response or percent viable tumor should be reported for
each tumor unless the number of intrapulmonary metastases are too numerous to count.
Recommendation 11
Ongoing neoadjuvant studies with targeted therapies and immunotherapies in resectable NSCLC represent a unique
source of information, and the International Association for the Study of Lung Cancer strongly recommends and will
promote the design and implementation of an international database to collect uniformly clinical and pathologic
information with the ultimate goal of fostering collaboration and to facilitate the identification of surrogate end points
of long-term survival.

Guidance for Surgeons: Suspect, Detect, and Refer for Treatment5,6
• irAEs frequently occur in the perioperative setting, either before or after surgical intervention
• irAEs occurring during neoadjuvant immunotherapy are generally manageable and in most cases should not exclude
patients from surgery
• The onus is on the surgeon to have a high degree of suspicion for potential toxicities in patients treated with immunotherapy
• Vague symptoms should not be dismissed, because nonspecific ailments can be indicative of severe toxicity
– Rheumatologic toxicities and endocrinopathies are some of the most difficult to recognize, given their relatively
nonspecific presentation
» For example, fatigue, poor energy, and low mood could represent hypophysitis or adrenal insufficiency
– Other toxicities can be essentially asymptomatic
» For example, renal and hepatic toxicity are generally only detected on routine labs
– Pneumonitis is another relevant irAE requiring awareness by surgeons, as severe pneumonitis could potentially
exclude patients from operative therapy, but significant pneumonitis has been rare in trials to date
• A comprehensive workup for irAEs, with a thorough history specifically targeted to potential irAEs, should be conducted
• Coordinate and collaborate with oncologists and other multidisciplinary experts to optimally diagnose and manage irAEs
in patients who have received/are receiving perioperative immunotherapy
• The National Comprehensive Cancer Network (NCCN) and American Society of Clinical Oncology (ASCO) have issued
guidelines for recognition and management of immune-related adverse events

How Should irAEs Be Diagnosed and Managed?
Minimal or No Symptoms; Diagnostic Changes Only
• In general, immunotherapy should be continued with close monitoring, with the exception of some neurologic, hematologic, and
cardiac toxicities
Mild to Moderate Symptoms
• Hold checkpoint inhibitor therapy for most grade 2 toxicities
• Consider resuming immunotherapy when symptoms and/or lab values revert to grade 1
• Corticosteroids (initial dose of 0.5-1.0 mg/kg/day of prednisone or equivalent) may be administered
Severe or Life-Threatening Symptoms
Grade 3 toxicities
• Hold checkpoint inhibitor therapy
• Initiate high-dose corticosteroids (prednisone 1-2 mg/kg/day or methylprednisolone IV 1-2 mg/kg/day)
• If symptoms do not improve with 48-72 hours of high-dose corticosteroid, infliximab may be offered for some toxicities
• Taper corticosteroids over the course of at least 4-6 weeks
• When symptoms and/or laboratory values revert to grade 1, rechallenging with immunotherapy may be considered; however,
caution is advised, especially in those patients with early-onset irAEs; dose adjustments are not recommended
Grade 4 toxicities
• In general, permanent discontinuation of checkpoint inhibitor therapy is warranted, with the exception of endocrinopathies that have
been controlled by hormone replacement
irAEs are often
diagnosed by exclusion;
other causes should be
ruled out (including AEs
of other therapies used),
but immunotherapy-related
toxicity should always be
included in the differential
There should be a high
level of suspicion that
new symptoms are
treatment related; early
recognition, evaluation,
and treatment of irAEs
plus patient education
are essential for the
best outcome
Depending on severity
of irAE, management
may require
corticosteroid or other
immunosuppressive
treatment and
interruption or
discontinuation of therapy
If appropriate
immunosuppressive
treatment is
used, patients generally
recover from irAEs
Use of immunosuppressive
therapy to manage
irAEs does not appear to
impact response to
immunotherapy
Grade 1
Grade 2
Grade 3/4

 Hold immunotherapy with radiographic evidence of pneumonitis progression
 May offer one repeat CT in 3-4 weeks; in patients who have had baseline testing, may offer a repeat
spirometry/DLCO in 3-4 weeks
 May resume immunotherapy with radiographic evidence of improvement or resolution; if no improvement,
should treat as grade 2
 Monitor patients weekly with history, physical examination, and pulse oximetry; may also offer CXR
Grade 2: Symptomatic; 1 lobe
of lung or 25%-50% of lung
parenchyma; medical intervention
indicated; limiting instrumental ADL
Grade 3: Severe symptoms
requiring hospitalization; involves
all lung lobes or 50% of lung
parenchyma; limiting self care
Grade 4: Life-threatening
respiratory compromise; urgent
intervention indicated (intubation)
 Hold immunotherapy until resolution to grade ≤1
 Prednisone 1-2 mg/kg/day and taper by 5-10 mg/week over 4-6 weeks
 Consider bronchoscopy with BAL
 Consider empiric antibiotics
 Monitor patients every 3 days with history, physical examination, and pulse oximetry; consider CXR; if no clinical
improvement after 48-72 hours of prednisone, treat as grade 3
 Discontinue immunotherapy
 Empiric antibiotics; methylprednisolone IV 1-2 mg/kg/day; if no improvement after 48 hours, may add infliximab
5 mg/kg, or mycophenolate mofetil IV 1 g 2x/day, or IVIG x 5 days, or cyclophosphamide
 Taper corticosteroids over 4-6 weeks
 Pulmonary and infectious disease consults if necessary
 Bronchoscopy with BAL +/- transbronchial biopsy
 Patients should be hospitalized for further management
How Should Pulmonary irAEs Be Diagnosed and Managed?
 Pneumonitis: focal or diffuse inflammation of the lung parenchyma (typically identified on CT imaging)
 Diagnostic work-up: CXR, CT, pulse oximetry; for grade ≥2, may include infectious work-up
Grade 1: Asymptomatic; confined
to 1 lobe of lung or 25% of lung
parenchyma; clinical or diagnostic
observations only
Additional considerations
• GI and pneumocystis prophylaxis may be offered to patients on prolonged steroid use (12 weeks)
• Consider calcium and vitamin D supplementation with prolonged steroid use
• Bronchoscopy + biopsy; if clinical picture is consistent with pneumonitis, no need for biopsy

358 people from 14 different countries
The researchers

Who took part in this study?
What treatments were used?
Why is this study important?
Some people with non–small cell lung cancer (NSCLC)
have tumors that can be removed surgically. However,
the cancer often comes back or spreads to other parts
of the body, which may subsequently lead to death
Taking chemotherapy (chemo) before or after surgery
can reduce the risk of cancer coming back and may
help people live longer. However, this only works for
some people
Nivolumab (nivo) is an immunotherapy; it works by
activating a person’s immune system to fight back
against cancer cells
The goal of the CheckMate -816 study was to find out if
nivo plus chemo works better than chemo alone when
given before surgery for NSCLC

What were the adverse events?
What do these findings mean?
A serious adverse event is one that is life threatening, requires going to
the hospital, or results in death
In CheckMate -816, people who took nivo plus chemo instead of
chemo alone before their surgery:
Lived longer without
the cancer getting worse
or spreading
Were more likely to have
lungs and lymph nodes
clear of cancer cells
after surgery
Had a trend of living longer
in general, which needs
more time to be confirmed
Did not have more
