[Effects of Modified Ruji Recipe in Preventing Relapse and Metastasis of Breast Cancer Patients with Negative Hormone Receptor].

Abstract

Objective To observe the effect of Ruji Recipe (RR) (treated by syndrome typing) in preventing the relapse and metastasis of invasive ductal breast cancer patients with negative hormone receptor (HR) after surgery and chemotherapy. Methods Using a prospective, cohort method, 136 pa- tients with stage I - III C HR negative invasive ductal breast cancer were equally assigned to the treat- ment group (treated by RR in syndrome typing way) and the control group (routine follow-ups). Disease free survival (DFS) , overall survival (OS) , relapse and metastasis were observed in the two groups. Re- sults All patients were followed-up for 15 to 57 months, with the median follow-up of 44 months. The median DFS and OS had not reached. The 1. 0, 1. 5, 2. -0, and 3. 0 years DFS were 94.1 % (64/68) , 86. 4 % (51/59), 81. 8% (45/55), and 72. 0% (36/50) in the treatment group. They were 77. 9% (53/68), 67.2% (45)67), 60. 6% (40)66), and 54. 5% (36/66) in the control group. Significant difference existed in 1. 0, 1. 5, and 2. 0 years DFS between the two groups (X² = 7.403, 6.426, 6.459; P =0. 012, 0.013, 0. 016). No statistical difference existed in 1. 0, 1. 5, 2. 0, and 3. 0 years OS between the two groups (P >0. 05). Among triple negative breast cancer (TNBC) patients, 1. 0, 1. 5, 2. 0, and 3. 0 years DFS were 97. 0% (32/33), 92. 9% (26/28), 92.6% (2527), and 84. 6% (22/26) in the treatment group, 81. 5% (2227), 66. 7% (1827), 61. 5% (16/26), and 57. 7% (15/26) in the control group. Of them, significant difference existed in 1. 5, 2. 0, and 3. 0 years DFS between the two groups (X² =5. 893, 7. 293, 4. 591 ; P = 0. 015, 0. 007, 0. 032). At the end of follow-ups, relapse and metastasis occurred in 15 patients, local recur- rence in 2 patients, single organ metastasis in 6 patients, and multiple organs metastasis in 7 patients of the treatment group. The relapse and metastasis occurred in 30 patients , local recurrence in 2 patients , single organ metastasis in 12 patients, and multiple organs metastasis in 16 patients of the treatment group. Conclusions RR ( by syndrome typing) could improve DFS and delay progression of invasive ductal breast cancer patients with negative HR in the first 2 years after surgery. It also had certain value for relapse and metastasis of TNBC patients within 2 years.
