AbstrakKanker payudara merupakan kanker yang paling sering mengenai perempuan dan menjadi penyebab kematian terbanyak akibat kanker pada perempuan. Angka kejadian kanker payudara bervariasi secara global dimana terjadi peningkatan insiden di negara berkembang tetapi cenderung menurun di negara maju. Gambaran klinikopatologi kanker payudara dapat bervariasi sesuai kelompok usia dan memiliki peran penting dalam faktor prognostik penyakit.Tujuan penelitian ini adalah untuk mengetahui hubungan usia dengan gambaran klinikopatologi kanker payudara.Gambaran klinikopatologi meliputi stadium klinis, subtipe histologi, dan gradasi histologi. Penelitian ini adalah penelitian analitik menggunakan metode cross sectional dengan teknik total sampling. Sampel penelitian yaitu data pasien kanker payudara primer di bagian bedah RSUP Dr. M. Djamil Padang periode Januari 2012 -Desember 2012.Dari 112 penderita kanker payudara primer hanya 46 yang memenuhi kriteria. Sampel penelitian dianalisis dengan uji chi square (p ≤ 0,05). Hasil penelitian ditemukan bahwa sebagian besar penderita berusia ≥ 40 tahun (78,3%) dan <50 tahun (67,4%), datang pada stadium lanjut (69,6%) dengan tipe invasive ductal carcinoma (87%) dan bergradasi rendah (78,3%). Analisis bivariat menunjukkan bahwa tidak terdapat hubungan yang bermakna antara usia dengan gambaran klinikopatologi kanker payudara.Kata kunci: kanker payudara, gambaran klinikopatologi, stadium klinis, subtipe histologi, gradasi histologi AbstractBreast cancer is now become the most common cancer diagnosed in women and the leading cause of deaths from cancer among women. The incidences of the disease vary globally, it has been reported to be increasing in developing countries while slightly down in developed countries. The clinicopathologic features of breast cancer may vary from each age groups and it has an important role as a prognostic factors. The objective of this study was to determine the relationship between age of the breast cancer patients and their clinicopathologic features. The clinicopathologic features i.e. staging, histologic subtypes, and histologic grades. This was an analythical study by using cross sectional method with total sampling technique. Samples were patients with primary breast cancer in Dr. M. Djamil GeneralHospital period January 2012 -December 2012. From 112 patients with primary breast cancer there were only 46 who fulfilled the criteria. The samples were analyzed by chi square test (p ≤ 0.05). The result of this study has revealed that most of the patients ≥ 40 years of age (78.3%) and < 50 years of age (67.4%), diagnosed in late stage (69.6%) with invasive ductal carcinoma (87%) and low histologic grade (78.3%). Bivariat analyze found that there is no significant relation between age and clinicopathologic features of breast cancer.
