This study examines multiple malignant tumors, excluding skin and certain intestinal cancers. It suggests assessing a patient's immune defense mechanisms is crucial alongside traditional tumor staging.

Area of Science:

  • Oncology
  • Immunology

Background:

  • Multiple malignant tumors are documented in medical literature, often through case reports or registry data.
  • Previous studies have excluded specific cancer types like skin and certain gastrointestinal malignancies from multiple tumor analyses.

Purpose of the Study:

  • To present a series of 71 cases of multiple malignant tumors.
  • To review literature and explore potential etiological factors for multiple tumors.
  • To emphasize the role of the tumor surveillance mechanism and its potential depression.

Main Methods:

  • A personal series of 71 cases from hospital follow-up clinics.
  • Exclusion of multiple skin tumors and specific intestinal growths.
  • Literature review on etiological factors of multiple tumors.

Main Results:

  • A series of 71 cases of multiple malignant tumors were identified and analyzed.
  • Possible etiological factors were considered based on literature review.
  • The importance of the tumor surveillance mechanism was highlighted.

Conclusions:

  • Depression of the body's defense mechanisms, potentially by major surgery, may contribute to multiple tumors.
  • Assessing a patient's immune defense mechanisms is as critical as tumor grading and staging.
