RationaleMultiple primary malignant neoplasms with tuberculosis are rare. The interaction between tuberculosis and tumor remains unclear. Moreover, the treatment of multiple primary tumors combined with tuberculosis is relatively complicated. Herein, we report a case of metachronous triple primary carcinoma complicated with pulmonary tuberculosis.ObjectiveThis report aims to analyze the clinical characteristics of 3 primary tumors combined with tuberculosis. We report the long-term survival of this patient after personalized treatment and this patient have a good quality of life.Diagnoses And InterventionsA 55-year-old male patient was diagnosed with squamous cell carcinoma of the lower thoracic esophagus (cT4bN1M0 IVA) and received concurrent chemoradiotherapy, followed by 2 cycles consolidate chemotherapy. During the follow-up, he was diagnosed with secondary tuberculosis (TB) and accepted anti-TB treatment. During anti-TB treatment, he was diagnosed with squamous cell carcinoma of the oropharynx (cT1N0M0 I P16(-)), then he received radical radiation therapy. However, within a year, the patient was diagnosed with oral squamous cell carcinoma (cT3N0M0 IIIA). He accepted an individualized chemotherapy with paclitaxel combined with capecitabine. Moreover, immunohistochemistry of the patient's 3 biopsies indicated positive P53 expression.OutcomesSince the patient suffered from esophageal cancer, oropharyngeal cancer, and oral floor cancer, no tumor recurrence or metastasis was observed. And he has a good quality of life. Tuberculosis, TP53 mutation, radiotherapy, smoking, and drinking history may be risk factors for multiple primary tumors.LessonsThe treatment of multiple primary tumors combined with pulmonary tuberculosis is complicated. Individualized treatment allows patients to achieve long-term survival while also having a good quality of life. Limitations in this case: surgery may be an alternative strategy for the patient, but the patient refused surgery.Copyright © 2024 the Author(s). Published by Wolters Kluwer Health, Inc.
