Objectives

Narrative objectives1

This study will be conducted in accordance with PRISMA 2020 guidelines as a systematic review and meta-analysis. A comprehensive search will be conducted in PubMed, Web of Science, and Ichushi for English-and Japanese language articles published since 2000 that report on the treatment and outcomes of cervical lymph node or parotid gland metastases from eyelid sebaceous carcinoma.

Basic objectives2

Others

Basic objectives -Others

The following data will be extracted:
Patient demographics and tumor characteristics, site of metastasis (cervical nodes, parotid gland), extent of parotidectomy (partial vs total), neck dissection (prophylactic vs therapeutic vs none), use of postoperative radiotherapy, time from primary tumor treatment to metastasis (short vs long), number of metastatic lesions (solitary vs multiple)

Trial characteristics_2


Developmental phase



Assessment

Primary outcomes

Meta-analysis will compare the following binary variables with respect to local recurrence rate, overall survival (OS), and disease-free survival (DFS), presenting relative risks (RR) or hazard ratios (HR):
solitary vs multiple metastases
short vs long interval from primary treatment to metastasis
partial vs total parotidectomy
with vs without postoperative radiotherapy
with vs without prophylactic neck dissection
Heterogeneity will be assessed using the I2 statistic. Random-effects models will be applied when appropriate. Publication bias will be evaluated using funnel plots and Egger's test. Where meta-analysis is not feasible, narrative synthesis will be provided.

Key inclusion criteria

Population
Patients with sebaceous carcinoma of the eyelid who developed cervical lymph node and/or parotid gland metastases.
Intervention / Exposure
Surgical management including parotidectomy, neck dissection, and/or postoperative radiotherapy.
Outcomes
Studies reporting at least one of the following:
Local recurrence rate
Overall survival (OS)
Disease-free survival (DFS)
Study Design
Case reports, case series, retrospective cohort studies, or other observational studies.
Language
Articles published in English and Japanese
Publication Year

Key exclusion criteria

Primary site other than eyelid
Studies on extraocular sebaceous carcinoma (e.g., trunk, scalp).
No relevant metastasis
Studies that do not describe cervical lymph node or parotid gland involvement.
Lack of treatment or outcome data
Articles that do not report surgical details or oncologic outcomes.
Non-human studies, reviews, conference abstracts, editorials, or letters without original patient data.
Duplicate publications
When multiple reports describe the same patient cohort, only the most comprehensive report will be included.
