Multiple malignant primary tumors (non-head and neck): Contemplation needed.

Background: The incidence of multiple malignant primary tumors (MMPT) is increasing which needs attention. Hence, we undertook this study to analyze clinico-demographic details and treatment outcomes in patients with non-head and neck MMPT.

Materials And Methods: Hospital case records of patients with histopathology proven MMPT registered in the radiation oncology department from January 1, 2008 to December 31, 2020 were retrospectively studied.

Multiple primary head and neck squamous cell cancer: Lessons learnt.

Aim: To analyze the demographic profile, treatment outcome, and factors affecting them in multiple primary head and neck squamous cell cancer (MPHNSCC) patients.

Materials And Methods: Hospital case records of patients with histopathology proven MPHNSCC registered in the radiation oncology department from January 2008 to December 2020 were retrospectively studied. Modified Warren-Gates criteria were used to define MPHNSCC.
