Аннотация
BACKGROUND: An increasing number of reports showed patients with bulky tumors after lattice radiation therapy (LRT) treatment achieved good local control. However, in these reports, LRT was previously used primarily for palliation. We reported a case that LRT plays a synergistic role in the radical treatment of locally advanced bulky cervical cancer (LABCC) combined with INTERLACE study protocol.
METHODS: The patient was a 54-year-old female with LABCC and treated with LRT combined with the INTERLACE study protocol. She received three fractions of 3 Gy each to the gross tumor volume (GTV) and three fractions of 9 Gy each to the lattice therapy volume (LTV), on an emergent basis, using volumetric modulated arc therapy (VMAT). Subsequently, according to the INTERLACE study protocol, chemotherapy and radiotherapy were carried out and the standard follow-up examinations were conducted. Adverse events (AEs) were assessed according to the Common Terminology Criteria for AEs (CTCAE) version 5.0.
RESULTS: The patient initially received LRT, which reduced the tumor burden and controlled bleeding. After this was combined with the INTERLACE study protocol, the complete clinical response (cCR) was achieved and they maintained this status for 13 months after the completion of concurrent chemoradiotherapy (CCRT), with only manageable grade IV hematological toxicity observed after the completion of CCRT. During this period, only manageable grade IV hematological toxicity (platelet count 16 × 109/L, white blood cell count 0.33 × 109/L) was observed.
CONCLUSIONS: In this case, LRT combined with INTERLACE study protocol appears to be a safe and effective for the treatment of LABCC which improved the patient's quality of life without uncontrolled treatment-related toxicity.
