20110072 Multiplicity Counter/Date Multiple Tumors--Bladder: How are these fields coded when multiple tumors were present at the time of diagnosis and another tumor diagnosed a year later is determined to be the same primary? See Discussion.
20071098 Multiplicity Counter/Date of Multiple Tumors/CS Tumor Size--Lung: How are these fields to be coded when work-up of a malignancy spans a couple of months and reveals developing nodules? See Discussion.
20071090 Multiplicity Counter/Type of Multiple Tumors--Breast: How are these data items coded for a single breast primary composed of both in situ and invasive disease when measurements are provided for both the invasive and in insitu components? See Discussion.
20091131 Multiplicity Counter/Type of Multiple Tumors--Breast: How are these fields coded when a patient underwent a lumpectomy demonstrating two measured foci of invasive ductal carcinoma (1.5 cm and 3 mm) and "focally seen" in situ ductal carcinoma (DCIS) followed by a re-excision that is positive for 1.5 mm focus of residual invasive carcinoma? See Discussion.
20081066 Multiplicity Counter/Type of Multiple Tumors--Breast: How should these fields be coded when path shows a 1.2 cm infiltrating carcinoma with lobular features and several foci of infiltrating lobular carcinoma [7 foci described as multifocal], 1 large focus, and numerous foci of LCIS and CIS with lobular and ductal features? Should we count the foci or separate tumor nodules, ignore them, or code unknown values for these fields? See Discussion.
20071043 Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
20081006 Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"?
20081069 Multiplicity Counter: Should this field be coded to 99 for cases of familial adenomatous polyposis (FAP)? See Discussion.
20061050 Neoadjuvant Treatment/Date Therapy Initiated--Breast: If Tamoxifen has been used since 2000 for the treatment of hyperplasia, should it be coded as neoadjuvant treatment for a 2004 diagnosis of breast cancer?
20041007 Other Cancer-Directed Therapy--Hematopoietic, NOS: How is this field coded when transfusions are used to treat acute leukemia or thrombocythemia?
