The effect of four interventions on the
informational content of histopathologyreports
of resected colorectal carcinomas.Cross SS,
Feeley KM, Angel CA.
  • free text with no agreed guidelines
  • text guidelines
  • template proformas
  • All interventions produced some increase in
    inclusion rate for some features, but only with
    the introduction of template proformas did these
    rates approach 100 for all data items. Inclusion
    rates were 100 for all items in all cases
    reported using a proforma.

Valutazione tumore residuo
  • Rx presenza di tumore residuo non valutabile
  • R0 assenza di tumore residuo diagnosticabile
    (considera la situazione obiettiva dopo
    lintervento ad es. un paziente con metastasi a
    distanza rimosse radicalmente appartiene al IV
    stadio ma la resezione è R0).
  • R1 Presenza di neoplasia microscopica. A questa
    categoria appartengono anche quei pazienti il cui
    lavaggio peritoneale, appena dopo la laparotomia,
    è positivo per cellule neoplastiche anche se la
    resezione della neoplasia risulta poi curativa.
  • R2 Presenza di neoplasia residua macroscopica

Chemotherapy response scoring - Dworak
  • Grade 0 No regression
  • Grade 1 Minimal regression dominant tumor mass,
    obvious fibrosis and/or vasculopathy
  • Grade 2 Moderate regression dominantly fibrotic
    changes, few tumor cells or groups (easy to find)
  • Grade 3 Good regression very few (difficult to
    find) tumor cells in fibrotic tissue with or
    without mucin
  • Grade 4 Total regression no tumor cells, only
    fibrotic mass or mucin
  • Poor response grade 0-2
  • Good response grade 3-4

Conclusions from a study of venous invasion
instage IV colorectal adenocarcinoma A
Sternberg, M Amar, R Alfici and G Groisman
Journal of Clinical Pathology 20025517-21
  • The addition of an elastic fibre stain enables
    the identification of venous invasion in a large
    proportion of colorectal carcinomas that are
    falsely negative on haematoxylin and eosin alone
  • It is probable that only minimal venous invasion
    is needed to seed clinically important distant
    metastases
  • Both extramural and intramural venous invasion
    may seed clinically important haematogenous
    metastases

Valutazione dellescissione del mesoretto
  • ottimo il mesoretto è intatto o presenta solo
    irregolarità minori della fascia propria del
    retto (liscio, lucente). Le irregolarità non
    devono superare i 5mm, non deve esserci
    conizzazione del mesoretto.
  • moderato irregolarità della superficie della
    fascia propria del retto (gt a 5mm), conizzazione
    moderata. In nessun punto viene visualizzata la
    muscolare propria tranne che nel punto di
    inserzione dei muscoli elevatori. Sulle fette di
    3-5 mm si visualizzano solo irregolarità moderate
    del margine circonferenziale.
  • scarso evidenti difetti del mesoretto con
    esposizione della muscolare propria e /o
    accentuata irregolarità del margine
    circonferenziale alla sezione.

Histopathological detection of lymph
nodemetastases from colorectal carcinomaJ Clin
Pathol 2000 53685-687
  • 72 colorectal carcinoma resection specimens
  • Lymph nodes up to approximately 5 mm in maximum
    extent were processed in entirety, without prior
    sectioning, and assessed histologically at three
    levels
  • In one case, this led to the detection of the
    only nodal metastasis present and therefore
    "upstaged" the tumour from Dukes's B to C
  • The assessment of multiple sections of lymph
    nodes from colorectal specimens leads to the
    detection of only a small number of additional
    nodal metastases. The method involves increased
    workload for pathologists and laboratory staff.
