PURPOSE: To understand how breast cancer is diagnosed in Gaza, and disease stage distribution, treatment, and survival.
MATERIALS AND METHODS: A clinical record case series study of women diagnosed in 2017 and 2018 was conducted with follow-up until December 31, 2020. Breast cancer crude incidence rates and age-specific incidence rates were calculated. Clinical characteristics, including investigation, diagnosis, and treatment methods by year of diagnosis, were compared using the chi-square test. The 2-year cumulative risk of death from any cause was estimated using the Kaplan-Meier method, and univariate and multivariate Cox proportional hazard regressions estimated hazard ratios and their 95% CIs.
RESULTS: Five hundred twenty-four new diagnoses (mean age, 53 years; range, 23-100) were recorded, giving a crude annual incidence rate of 27 per 100,000 population. Six percent (32/524) were diagnosed at stage I, 35% (185/524) at stage II, 33% (171/524) at stage III, and 19% (99/524) at stage IV. More than one half (52%, 271/524) underwent modified radical mastectomy. Seventy-seven percent (405/524) received chemotherapy, 70% (368/524) hormone therapy, and 39% (204/524) radiotherapy. Data on key prognostic factors were mostly available-stage (93%), estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2; 82%), tumor grade (77%), and tumor size (70%). The overall survival was 95.4% at 1 year and 86.6% at 2 years.
CONCLUSION: Women with breast cancer in Gaza have a high short-term survival after diagnosis. However, one half were diagnosed with advanced disease, and their investigations were incomplete. Better reporting on family history, tumor grade, size, and ER, PR, and HER2 receptor status is needed for future studies.
