Institution\u2010based real\u2010world data are limited in Bangladesh. This study aimed to describe the clinicopathological characteristics, molecular subtype distribution, documented treatment patterns, and progression\u2010related outcomes of breast cancer patients managed at a tertiary care center in Bangladesh.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective observational study was conducted at Bangladesh Specialized Hospital, Dhaka, Bangladesh. Hospital records of 1058 adult breast cancer patients were reviewed. Data on demographics, tumor characteristics, molecular subtype, documented treatment modalities, and follow\u2010up were analyzed. Progression\u2010free survival (PFS) was assessed using Kaplan\u2013Meier methods and Cox proportional hazards regression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Luminal A was the most common primary molecular subtype, accounting for 38.47% of cases, followed by TNBC at 23.53% and HER2\u2010positive disease at 11.91%. Documented metastatic or recurrent disease during the available records was present in 34.59% of patients, while Stage III or IV disease at diagnosis accounted for 33.65% of the cohort. Chemotherapy was the most frequently documented treatment modality, recorded in 79.02% of patients, followed by endocrine therapy in 53.78%, breast surgery in 56.52%, HER2\u2010directed therapy in 21.17%, and radiotherapy in 20.04%. Among luminal cases, endocrine therapy was documented in 86.61%, and among the HER2\u2010positive analytical subgroup, HER2\u2010directed therapy was documented in 85.96%. A total of 59 PFS events were recorded, comprising 58 progression events and one death. In multivariable Cox analysis, Luminal B, HER2\u2010negative disease, adjusted hazard ratio 2.97, 95% CI 1.41 to 6.23,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.004, and HER2\u2010positive disease, adjusted hazard ratio 2.70, 95% CI 1.39 to 5.26,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003, were associated with poorer PFS relative to Luminal A.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this institution\u2010based cohort, molecular subtype remained an important determinant of progression\u2010related outcome. Luminal A showed the most favorable progression\u2010related profile, whereas Luminal B, HER2\u2010negative, and HER2\u2010positive disease had poorer PFS.
