Over ten years, 70 patients with soft tissue sarcoma were treated for their primary tumors at the hospital of The Fox Chase Cancer Center. The clinical characteristics of these tumors are correlated with the outcome of various management efforts. The results of these evaluations identify three groups that can provide the basis for future treatment decisions and stratification for randomized studies of management options. The first group of patients, those with small well differentiated tumors, have no systemic spread regardless of the treatment modality used. The second group, those with large (greater than 5 cm) tumors that are moderately or poorly differentiated, do uniformly poorly despite the management techniques used. An intermediate group, those with high grade or large size but not both, have outcomes which may be correlated to treatment modalities.
Two hundred seventy‐five patients with breast cancer and no axillary metastases had mastectomies and axillary node dissection performed during the period between 1970 and 1979 at The Fox Chase Cancer Center. They had a mean age of 60 years (range, 21–91) and 38 (14%) patients have had recurrence to date. Poor histologic differentiation and skin involvement were related to a high risk of recurrence. Those patients with skin infiltration by tumor or a poorly differentiated tumor had a 53 ± 9% expected five‐year tumor‐free survival, whereas patients without these had a 90 ± 2% expected five‐year tumor‐free survival. Tumor involvement of the lymphatic vessels within the breast and estrogen receptor protein positivity or negativity were not helpful for identifying a subpopulation at increased risk of recurrence. Large tumor size was not a poor prognostic indicator for a patient subpopulation. These factors should be considered as indicators for inclusion in clinical trials and adjuvant therapy and used as stratification points for the analysis of the data developed in these trials.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
